Description

[0001] This application is a divisional application filed pursuant to Article 48 of the Implementing Regulations of the Patent Law. The parent application is Chinese Utility Model Application No. CN202421486236.6, filed on June 26, 2024, with a priority date of July 14, 2023, and priority number 202310861990.7, entitled "Integrated Cutting and Grinding Equipment for Small-Density Rectangular Bars," filed by Shanghai Rijin Machine Tool Co., Ltd. The entire contents of the parent application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of silicon workpiece processing technology, and in particular to a half-rod grinding device. Background Technology

[0003] In the relevant processing technology for silicon rods, several processes are involved, such as squaring, grinding, and rounding / beveling. Generally, most existing silicon rods are cylindrical in shape. By squaring the silicon rod using a silicon rod squaring equipment, the cross-section of the silicon rod after squaring is shaped into a rectangular (including square) form, and the overall squared silicon rod becomes a cuboid (or possibly a cube) shape. Rectangular shapes include rectangles with adjacent sides orthogonal or within a predetermined angle, rectangles with rounded corners between adjacent sides, and rectangles with connecting short sides between adjacent sides.

[0004] Taking monocrystalline silicon rods as an example, in some related technologies, the process of forming monocrystalline silicon rods may include: first, using a silicon rod cutting machine to cut the original long silicon rod into multiple short silicon rod segments; after cutting, using a silicon rod squaring machine to square the short silicon rods to form monocrystalline silicon rods with a rectangular cross-section. For specific implementations of using a silicon rod cutting machine to cut the original long silicon rod into multiple short silicon rod segments, refer to patent publications such as CN105856445A, CN105946127A, and CN105196433A. For specific implementations of using a silicon rod squaring machine to square the short silicon rods to form monocrystalline silicon rods with a rectangular cross-section, refer to patent publications such as CN105818285A. However, the formation process of monocrystalline silicon rods is not limited to the aforementioned technologies. In optional examples, the formation process of monocrystalline silicon rods may also include: first, using a full silicon rod squaring machine to square the original long silicon rod to form a long monocrystalline silicon rod with a rectangular cross-section; after squaring, using a silicon rod cutting machine to cut the squared long monocrystalline silicon rod to form a short-crystal silicon rod. For a detailed implementation of using a full silicon rod squaring machine to square the original long silicon rod to form a rectangular long monocrystalline silicon rod, please refer to, for example, patent publications such as CN106003443A.

[0005] After a cylindrical single-crystal silicon rod is square-cut into a rectangular-shaped silicon rod using a squaring device, a grinding device can be used to perform operations such as grinding, rounding / beveling on the rectangular-shaped silicon rod. For specific implementation methods of grinding, rounding / beveling on the rectangular-shaped silicon rod using the aforementioned grinding device, please refer to, for example, patent publications such as CN105835247A.

[0006] With the development of battery technology, the demand for small silicon wafers is increasing, and the demand for thinner wafers is also relatively large. The thinner the silicon wafer, the more difficult it is to cut, and the harder it is to guarantee the cutting quality. For example, in current technology, slicing is performed on large square silicon rods. If the required thickness of the silicon wafer is to be cut, it undoubtedly increases the difficulty of silicon wafer slicing. During the slicing process, the cross-section of the silicon wafer is more prone to damage and defects. Moreover, for slicing large square silicon rods, in order to minimize the damage and defects of the silicon wafer, the slicing speed must be controlled, which reduces the slicing efficiency. Therefore, the industry has proposed certain improvements to the current technology. For example, the existing large square silicon rods are first cut, such as cutting the large square silicon rod in half to form two smaller square silicon rods, and then the smaller square silicon rods are subjected to subsequent processing such as grinding and slicing.

[0007] However, there is no suitable dedicated equipment for grinding smaller square silicon rods in the current technology. In existing equipment technology, the work required for each process (such as grinding, chamfering, etc.) is arranged independently, and the corresponding processing equipment is scattered in different production units or workshops, or multiple production workshops of the same production unit are distributed in different production areas. The conversion of workpieces for different processes requires handling and allocation, and pre-processing may be required before each process. This makes the process complicated, inefficient, and easily affects the quality of silicon rod processing. It requires more manpower or transfer equipment, and poses significant safety hazards. In addition, there are many flow links between the equipment of each process, which increases the risk of workpiece damage during workpiece transfer, easily leads to non-production factors causing defects, reduces the product pass rate, and causes unreasonable losses due to existing processing methods. Summary of the Invention

[0008] In view of the shortcomings of the above-mentioned related technologies, the purpose of this application is to provide a half-bar grinding equipment, which aims to solve the problem that the existing technology cannot perform integrated operations of multiple processes such as grinding and chamfering of half-bars.

[0009] To achieve the above and other related objectives, the first aspect of this application provides a half-bar grinding apparatus, comprising: a grinding machine base having a grinding platform, the grinding platform having a grinding surface area and a chamfering area; a grinding device disposed in the grinding surface area for grinding the side surface of the half-bar located in the grinding surface area; the grinding device including a grinding frame and a grinding unit movably disposed on the grinding frame or a pair of grinding units disposed opposite each other, each grinding unit having at least one grinding tool; a chamfering device disposed in the chamfering area, including at least one for chamfering the edge of the half-bar located in the chamfering area, the chamfering device including a chamfering frame and at least one chamfering unit movably disposed on the chamfering frame, each chamfering unit having at least one chamfering tool; and a half-bar transfer device disposed in the grinding machine base for transferring the half-bar between the various functional areas.

[0010] In summary, the semi-bar grinding equipment provided in this application uses a grinding device to grind the side surface of the semi-bar located in the grinding area, and a chamfering device to chamfer the edge of the semi-bar located in the chamfering area, thereby realizing the integrated operation of multiple processes such as grinding and chamfering of the semi-bar, improving production efficiency and product processing quality.

[0024] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. In view of the various deficiencies of the prior art, the applicant has previously proposed an integrated square silicon rod cutting and grinding machine, which combines a cutting device and a grinding device. The cutting device can perform a transverse cutting operation on a horizontally placed original square silicon rod to form two smaller square silicon rods (half rods). The grinding device can perform a grinding operation on the two square silicon rods (half rods) formed after transverse cutting, thereby completing the integrated operation of cutting and grinding the original square silicon rod in half, improving production efficiency and product processing quality. For specific implementation methods of the above-mentioned grinding equipment for transverse cutting and grinding operations on large square silicon rods, please refer to, for example, patent publications such as CN115946248A and CN115871115A. However, in the above technical solution, the original square silicon rod that has completed the square cutting operation is cross-cut to form two square silicon rods (half rods). The original square silicon rod with a circular cross section needs to be square-cut to form a rectangular (or square) original square silicon rod in other silicon rod square cutting equipment.

[0025] In view of this, this application proposes an integrated cutting and grinding equipment and a half-rod cutting and grinding method for small-sized rectangular rods. The integrated cutting and grinding equipment for small-sized rectangular rods includes a half-rod cutting device and a half-rod grinding device that are connected to each other. The half-rod cutting device is used to perform square cutting and halving operations on silicon rods with circular cross-sections to form at least two half-rods with rectangular cross-sections. The half-rod grinding device is used to perform grinding and chamfering operations on the half-rods, thereby completing the integrated operation of multiple processes such as square cutting, halving, grinding and chamfering of the original silicon rod with circular cross-sections. The equipment has a high degree of integration, simple structure, improves production efficiency and saves costs, and improves the quality of product processing.

[0026] In the embodiments disclosed in this application, to clarify the definition of directions and the operation between different structures, a three-dimensional space is defined by a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are all straight lines and are mutually perpendicular. The depth extension direction of the small-size rectangular bar cutting and grinding integration equipment, that is, the length direction when the silicon bar is placed on it, is defined as the first direction (i.e., the front-back direction or the transfer direction). The width extension direction of the small-size rectangular bar cutting and grinding integration equipment, that is, the left-right direction, is defined as the second direction (i.e., the left-right direction or the transposition direction). The vertical direction, that is, the vertical direction, the perpendicular direction, the up-down direction, or the lifting direction, is defined as the third direction.

[0027] In this application, the integrated cutting and grinding equipment for small-size rectangular rods can also be called a half-rod cutting and grinding machine; small-size rectangular rods are silicon rods with circular cross-sections that are square-cut and halved, so that the silicon rod is formed into two half-rods with rectangular cross-sections. Therefore, "half-rod" can also be referred to by other terms, such as "small-size rectangular rod", "sub-rod", "sub-rod", "small silicon rod", "small square rod", etc.

[0028] This application discloses a method for cutting and grinding a half-rod, comprising the following steps: performing square cutting and halving operations on a silicon rod with a circular cross-section, so that the silicon rod is formed into at least two half-rods with a rectangular cross-section; and performing grinding and chamfering operations on the half-rods.

[0029] The step of performing square root cutting and halving operations on a silicon rod with a circular cross-section to form at least two halves of a rectangular cross-section includes: performing a first cutting operation on the silicon rod with a circular cross-section along the length direction of the silicon rod to form two parallel first side cut surfaces; and performing a second cutting operation on the silicon rod with the two first side cut surfaces along the length direction of the silicon rod to form at least two halves of a rectangular cross-section after the silicon rod passes through two parallel second side cut surfaces and at least one slit surface located between the two second side cut surfaces, wherein the second side cut surfaces are perpendicular to the first side cut surfaces and the slit surface is parallel to the second side cut surfaces.

[0030] The steps for grinding and chamfering a half-bar include: grinding the two first sides of the half-bar; grinding the two second sides of the half-bar; and chamfering the four edges of the half-bar.

[0031] This application also discloses an integrated cutting and grinding equipment for small-sized rectangular rods, capable of performing multiple integrated operations such as squaring, halving, grinding, and chamfering of primary silicon rods with circular cross-sections. The following provides a detailed description of the integrated cutting and grinding equipment for small-sized rectangular rods of this application.

[0032] Please see Figure 1 The image shown is a schematic diagram of the integrated cutting and grinding equipment for small-sized rectangular bars in one embodiment of this application. Figure 1 As shown, the integrated cutting and grinding equipment for small rectangular rods in this application includes: a half-rod cutting device 1, a silicon rod loading and unloading device 17, and a half-rod grinding device 2 connected to each other. The half-rod cutting device 1 is used to perform square cutting and halving operations on silicon rods with circular cross-sections to form at least two half-rods with rectangular cross-sections. The half-rod grinding device 2 is used to perform grinding and chamfering operations on the half-rods transferred from the silicon rod loading and unloading device 17 in the half-rod cutting device 1.

[0033] Please see Figure 2 Displayed as Figure 1 A structural schematic diagram of a half-bar cutting device. Regarding half-bar cutting device 1, combined with... Figure 1 and Figure 2 The half-rod cutting device 1 includes: a cutting machine base 11, a first silicon rod transfer device 12, a first silicon rod cutting device 13, a second silicon rod transfer device 14, and a second silicon rod cutting device 15. It should be noted that, in the case of... Figure 1 In the illustrated embodiment, the settings of the first direction, the second direction, and the third direction are shown in the figure. Specifically, the first direction is... Figure 1 The second direction is the X-axis in the diagram. Figure 1 The Y-axis in the diagram, the third direction is... Figure 1 The Z-axis in the diagram.

[0034] The cutting machine base, as the main component of a half-bar cutting device, provides a processing platform. In practical applications, the cutting machine base is relatively large in size and weight to provide a large mounting surface and robust overall machine stability. It should be understood that the cutting machine base can serve as a seat for different structures or components performing processing operations within the half-bar cutting device, and its specific structure can be modified based on different functional or structural requirements. In some examples, the cutting machine base includes fixing or limiting structures for supporting different components within the half-bar cutting device, such as a base, column, or frame, all of which are cutting machine bases as described in this application.

[0035] Meanwhile, in some examples, the cutting base can be a single, integrated base, while in others, the cutting base can include multiple independent bases.

[0036] The cutting machine base has a cutting platform, which can be divided into multiple functional areas according to the specific work content of the silicon rod processing operation. In some embodiments, the cutting platform has one or more cutting station groups, each cutting station group including a first cutting station and a second cutting station arranged in parallel. Therefore, in such cases... Figure 1 and Figure 2 In the illustrated embodiment, the cutting processing platform has a cutting station group, which includes a first cutting station and a second cutting station arranged in parallel along a second direction. Each cutting station includes a loading / unloading area and a cutting area; that is, the first cutting station includes a first loading / unloading area and a first cutting area, and the second cutting station includes a second loading / unloading area and a second cutting area. However, this is not a limitation; please refer to [reference needed]. Figure 4 The diagram shows a schematic representation of a half-bar cutting device in another embodiment. Figure 4 In the illustrated embodiment, the cutting platform of the half-bar cutting equipment has two cutting station groups, wherein each cutting station group includes a first cutting station and a second cutting station arranged in parallel along a second direction. In such a way... Figure 1 and Figure 2 In the embodiments shown, or in such Figure 4 In the embodiment shown, a first silicon rod transfer device 12 and a first silicon rod cutting device 13 are configured for the first cutting station, and a second silicon rod transfer device 14 and a second silicon rod cutting device 15 are configured for the second cutting station.

[0037] The first cutting station includes a first loading / unloading area and a first cutting area. A first silicon rod transfer device is installed at the first cutting station. This device carries a circular silicon rod and transfers it between the first loading / unloading area and the first cutting area along a transfer direction. A first silicon rod cutting device is located at the first cutting area and includes at least one first wire saw. This wire saw is positioned within a vertical plane and is either arranged vertically or at an angle to the vertical. The first silicon rod cutting device and the first silicon rod transfer device move relative to each other along the transfer direction, allowing the at least one wire saw to perform a first cut on the circular silicon rod, resulting in two parallel first side cuts on the silicon rod. The vertical plane is formed by a first direction and a third direction.

[0038] The first silicon rod transfer device is used to carry silicon rods along a transfer direction between a first loading / unloading area and a first cutting area at a first cutting station. The silicon rod (with a circular cross-section) is horizontally placed on the first silicon rod transfer device, and the axis of the silicon rod is aligned with the transfer direction, which is the same as the first direction. In some embodiments, the first silicon rod transfer device may include: a first transfer channel, a first support platform, and a first transfer drive mechanism.

[0039] The first transfer channel is positioned along the transfer direction. In some implementations, the first transfer channel includes a first transfer guide. The length of the first transfer channel in the transfer direction is greater than the length of the silicon ingot to be cut.

[0040] The first support platform is located on the first transfer channel to support the silicon rod. After being supported by the first support platform, the silicon rod is horizontal, that is, the axis of the silicon rod is consistent with the transfer direction (i.e., the first direction).

[0041] The first transfer drive mechanism is used to drive the first carrier platform and the silicon rod it carries to move along the transfer direction in the first transfer channel.

[0042] In some embodiments, the first carrier platform includes at least two first carrier members spaced apart along the transfer direction.

[0043] In some embodiments, the first carrier includes a first carrier support and a first carrier structure, wherein the first carrier support is disposed on a first transfer guide rail of the first transfer channel, and the first carrier structure is used to carry the silicon rod to be cut and to contact the arc surface of the silicon rod to be cut.

[0044] For some implementation details, please refer to [link / reference]. Figure 6 The diagram shows a structural schematic including a first silicon rod transfer device. Figure 6 As shown, the first support member 121 is a Y-shaped support structure. The first support member can adopt a Y-shaped support structure. The bottom of the Y-shaped support structure serves as a support bracket, and the upper fork of the Y-shaped support structure serves as the first support structure, wherein the inner inclined surface of the upper fork contacts the arc surface of the silicon rod to be cut. The top of the upper fork of the Y-shaped support structure can also have a certain width. When the Y-shaped support structure supports a horizontally placed silicon rod to be cut, the upper fork (i.e., the V-shaped part) of the Y-shaped support structure supports the silicon rod to be cut, and the two inner inclined surfaces of the upper fork contact the arc surface of the silicon rod to be cut. This allows the silicon rod with a circular cross-section to be centered, that is, the axis of the silicon rod to be cut corresponds to the center of the upper intersection (i.e., the bottom groove of the V-shaped part).

[0045] As previously stated, the first carrier platform includes at least two first carrier members spaced apart along the transfer direction, and the carrier surface formed by these first carrier members is adapted to the length of the silicon rod to be carried.

[0046] In some embodiments, the first carrier platform further includes: a first carrier drive mechanism for driving at least one first carrier to move along the transfer direction to adjust the carrier spacing between the two first carriers to accommodate silicon rods of different lengths.

[0047] In some embodiments, the first carrier drive mechanism includes: a first carrier moving guide rail, arranged along the transfer direction; and a first carrier drive unit for driving at least one first carrier to move along the first carrier moving guide rail.

[0048] In some embodiments, the first carrier drive unit may include: an adjusting gear track disposed along the transfer direction; an adjusting gear associated with the first carrier to be moved, and the adjusting gear meshing with the adjusting gear track; and an adjusting drive source for driving the adjusting gear to rotate so that the associated first carrier moves along the transfer direction. Wherein, when at least two first carriers in the first carrier platform are to be configured with the carrier drive unit, the adjusting gear track may be shared. For example, when two first carriers are to be configured with the aforementioned first carrier drive unit, it may include a shared adjusting gear track, a first adjusting gear and a first adjusting drive source associated with the first first carrier, and a second adjusting gear and a second adjusting drive source associated with the second first carrier.

[0049] In some embodiments, the first carrier drive unit may include: an adjusting screw disposed along the transfer direction and associated with the first carrier; and a screw drive source for driving the transfer screw to rotate so that the associated first carrier moves along the transfer direction. When at least two first carriers in the first carrier platform are to be configured with the first carrier drive unit, the adjusting screw may be shared, for example, a bidirectional screw. When two first carriers are to be configured with the aforementioned first carrier drive unit, a bidirectional screw and a screw drive source may be included. The bidirectional screw has threads at both ends with opposite thread directions, and both ends are associated with two opposing first carriers. In practical applications, the bidirectional screw is driven to rotate by a screw drive source (e.g., a servo motor) so that the two associated opposing first carriers move towards each other (the two first carriers move closer to each other) or away from each other (the two first carriers move further apart) along the bidirectional screw. The first transfer drive mechanism is used to drive the first carrier platform and the silicon rod it carries to move along the transfer direction in the first transfer channel.

[0050] In some embodiments, the first transfer drive mechanism includes: a first platform transfer guide rail, arranged along the transfer direction; and a first transfer drive unit, used to drive the first carrier platform to move along the first platform transfer guide rail.

[0051] In some embodiments, the first transfer drive unit includes a transfer rack, a transfer gear, and a gear drive source. The transfer rack is arranged along the transfer direction. The transfer gear is associated with and meshes with the transfer rack of a first support platform. In some embodiments, the transfer gear is associated with at least two first support members in the first support platform. The association of the transfer gear with at least two first support members in the first support platform can be achieved by the at least two first support members being joined by a connecting structure (e.g., a frame, connecting plate, connecting bracket, etc.), and the drive gear being disposed on the connecting structure. The gear drive source is used to drive the transfer gear to rotate so that the associated first support platform moves along the transfer direction. The gear drive source may be, for example, a servo motor.

[0052] In some embodiments, the first transfer drive unit includes a transfer screw and a screw drive source. The transfer screw is disposed along the transfer direction and associated with a first support platform. In some embodiments, the transfer screw is associated with at least two first support members in the first support platform. The association of the transfer screw with at least two first support members in the first support platform can be achieved by the at least two first support members being joined by a connecting structure (e.g., a frame, connecting plate, connecting bracket, etc.), and the transfer screw being associated with the connecting structure. The screw drive source is used to drive the transfer screw to rotate, thereby moving the associated first support platform along the transfer direction. The screw drive source may be, for example, a servo motor.

[0053] In practical applications, the aforementioned first carrier drive mechanism and first transfer drive mechanism have some overlapping functions. Therefore, in some embodiments, the function of the first carrier drive mechanism in driving at least one first carrier to move along the transfer direction to adjust the carrier spacing between the two first carriers can be accomplished by the first transfer drive mechanism.

[0054] The first silicon rod cutting device is located at the first cutting station and is used to perform the first cutting operation on the silicon rod to be cut by the first silicon rod transfer device at the first cutting area of ​​the first cutting station, so as to remove the opposite two sides of the silicon rod with a circular cross section, so that the silicon rod forms two parallel first side cut surfaces.

[0055] The first silicon rod cutting device includes at least one first wire cutting unit, which includes multiple first cutting wheels and a first cutting wire. The first cutting wire is sequentially wound around the multiple first cutting wheels to form at least one first cutting wire saw. The at least one first cutting wire saw is located in the vertical plane and is arranged vertically or at an angle to the vertical. The first wire cutting unit moves relative to the first silicon rod transfer device and the silicon rod to be cut carried by it at the first cutting station, and the at least one first cutting wire saw performs the first cutting operation on the silicon rod to be cut carried by the first silicon rod transfer device. The first cutting wire is wound in a loop between the first cutting wheels in a continuous loop manner. In this case, the first cutting wire can also be called a closed-loop cutting wire.

[0056] In some embodiments, such as Figure 1 and Figure 2 (or Figure 4 As shown in the figure, the first silicon rod cutting device 13 includes two first wire cutting units 131 arranged in parallel. Each first wire cutting unit includes: a plurality of first cutting wheels and a first cutting line. The first cutting line is wound around the plurality of first cutting wheels to form at least one first cutting line saw. The first cutting line saw is arranged along the vertical direction or at an angle to the vertical direction.

[0057] Please see Figure 5 The image shows a schematic diagram of the structure of the first wire cutting unit in a first silicon rod cutting apparatus in one embodiment. Figure 5 In the illustrated embodiment, the first silicon rod cutting device 13 includes two first wire cutting units 131. Each first wire cutting unit 131 includes a plurality of first cutting wheels 132 and a first cutting wire 134. The first cutting wire 134 is wound around the plurality of first cutting wheels 132 to form at least one first wire saw 135, wherein the first wire saw 135 is arranged vertically or at an angle to the vertical. Furthermore, the first silicon rod cutting device 13 may also include a first cutting mounting structure 130, on which the aforementioned plurality of first cutting wheels 132 are mounted.

[0058] In some embodiments, multiple first cutting wheels in the first wire cutting unit are connected to the first cutting mounting structure. Alternatively, multiple first cutting wheels are mounted on the first cutting mounting structure via a bracket, connecting plate, or mounting frame. The first cutting mounting structure serves as a carrier that associates multiple first cutting wheels in the first wire cutting unit with the first cutting frame or the first cutting seat. The specific form of the first cutting mounting structure can be a beam, plate frame, bracket, etc., and this application does not impose any limitations.

[0059] In the integrated cutting and grinding equipment for small-sized rectangular rods in this application, the first wire saw in the first wire cutting unit of the first silicon rod cutting device is arranged vertically or at an angle to the vertical.

[0060] like Figure 5As shown, in some embodiments, the first cutting mounting structure 130 is a rectangular frame, and the first cutting unit includes a plurality of first cutting wheels 132, for example, four first cutting wheels 132. The four first cutting wheels 132 are respectively located near the four corners of the first cutting mounting structure 130, and the wheel surface of each first cutting wheel 132 is located in a vertical plane (the vertical plane is composed of a first direction and a third direction). Two first cutting wheels 132 are in front (relatively closer to the first loading and unloading area) and arranged in parallel vertically, and the other two first cutting wheels 132 are in the back (relatively farther from the first loading area) and arranged in parallel vertically. The first cutting line 134 is wound around these four first cutting wheels 132 to form at least one first cutting line saw 135 (for example, the first cutting line saw 135 is formed between the two first cutting wheels 132 that are in front and arranged in parallel vertically). The first cutting line saw 135 is arranged along a third direction (i.e., vertically). In addition, in order for the first wire saw 135 to effectively cut the silicon rod, the first wire saw 135 must interfere with the silicon rod in the vertical direction.

[0061] In some embodiments, the first cutting lines are wound end-to-end between the respective first cutting wheels to form a loop cutting line (also known as a closed-loop cutting line). Figure 2 (or Figure 4 )and Figure 5 In the embodiment shown, the first cutting line 134 is wound around the plurality of first cutting wheels 132 in a head-to-tail manner to form a ring cutting line (also known as a closed-loop cutting line).

[0062] In the first cutting unit, multiple first cutting wheels are wound around a circular cutting wire. In this example, the first silicon rod cutting device can eliminate the need for a wire storage spool. The circular cutting wire, driven by a cutting wire drive device, can maintain high-speed operation. Furthermore, the circular cutting wire can run in the same direction during the cutting operation. Thus, the first silicon rod cutting device can achieve high-precision first cutting operations, avoiding problems such as wavy cut surfaces caused by wire reversal or speed changes in existing cutting methods. Simultaneously, the circular cutting wire effectively reduces the total length of the cutting wire required for the first wire cutting unit, lowering production costs.

[0063] In some embodiments, the cutting wire drive device is a motor with a power output shaft connected to the first cutting wheel. Thus, the first cutting wire can be driven by the wound second cutting wheel to run along the winding direction. Of course, in specific implementations, the cutting wire drive device can also be other drive sources such as a hydraulic motor, as long as it drives the first cutting wire; this application does not impose any limitations.

[0064] The first wire cutting unit in this application may further include a first transition wheel, which is used to reverse or guide the first cutting line, or the first transition wheel can be used to adjust the tension of the first cutting line. The number of first transition wheels may be one or more depending on the layout requirements.

[0065] The first transition wheel guides and pulls the first cutting wire, and simultaneously acts as a tensioning wheel to adjust the tension of the first cutting wire. The tensioning wheel is used to adjust the tension of the first cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0066] like Figure 5 As shown, in the first wire cutting unit, the first cutting mounting structure 130 is a rectangular frame. Each first wire cutting unit 131 includes multiple first cutting wheels 132 and multiple first transition wheels 133, for example, two first cutting wheels 132 and two first transition wheels 133, which are respectively located near the four corners of the first cutting mounting structure 130. The wheel surfaces of the two first cutting wheels 132 and the two first transition wheels 133 are located in the vertical plane. The two first cutting wheels 132 are arranged in front and parallel vertically, and the two first transition wheels 133 are arranged in the back and parallel vertically. The first cutting line 134 is wound around the two first cutting wheels 132 and the two first transition wheels 133 to form at least one first cutting wire saw 135 (for example, the first cutting wire saw 135 is formed between the two first cutting wheels 132). The at least one first cutting wire saw 135 is arranged vertically.

[0067] As before, the first cutting line 134 is wound around a plurality of first cutting wheels 132 or a plurality of first cutting wheels 132 and a plurality of first transition wheels 133 to form a first cutting line saw 135 between the two preceding first cutting wheels 132. Therefore, to adjust the line length of the first cutting line saw 135, the spacing between the two first cutting wheels 132 can be adjusted, which can be achieved by changing the position of at least one of the two first cutting wheels 132.

[0068] The first wire saw is located in the vertical plane and is arranged along the vertical direction or at an angle to the vertical direction. The silicon rod to be cut, carried by the first silicon rod transfer device at the corresponding first cutting station, is placed horizontally (the axis of the silicon rod to be cut is arranged along the transfer direction). Therefore, in order to cut the silicon rod to be cut, the length of the first wire saw is adapted to the size of the end face of the silicon rod to be cut. For example, the length of the first wire saw should be greater than or equal to the diameter of the silicon rod to be cut or the chord length of the silicon rod to be cut at the cutting position.

[0069] The direction of the first cutting wheel surface corresponds to the direction of the first cutting wire saw. It should be understood that the first cutting wheel surface is parallel to the plane where any of the first cutting wire grooves in the first cutting wheel are located. In order to control the cutting accuracy and the stability of the cutting process, the first cutting wire saw should be located in the plane where the first cutting wire groove is used to wind the first cutting wire. At the same time, during the cutting process, the direction of the force applied by the silicon rod to the first cutting wire should be parallel to the cutting wire groove, that is, the cutting wheel surface is parallel to the cutting direction. The cutting direction in the first cutting operation is the direction of the silicon rod axis, that is, the transfer direction (i.e., the first direction X-axis).

[0070] The first silicon rod cutting apparatus includes two first wire cutting units arranged in parallel, each first wire cutting unit having a first wire saw; therefore, the two first wire cutting units form two parallel wire saws. Figure 5 In the embodiment shown, the first silicon rod cutting device includes two first wire cutting units arranged in parallel along a second direction. Each first wire cutting unit has a first wire saw, which is arranged vertically. Thus, the two first wire saws belonging to the two first wire cutting units are both arranged vertically.

[0071] In fact, the first cutting wire saw can still have other variations. In some embodiments, the first cutting wire saw is arranged vertically, but this is not a limitation. In other embodiments, the position of the first cutting wire saw can be located in the vertical plane and arranged at an angle to the vertical (i.e., the third direction). The vertical plane is formed by the first direction and the third direction, and the angle is less than or equal to 10 degrees (≤10°), or less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). That is, the wire cutting direction of the first cutting wire saw can be located in the vertical plane with the third direction (i.e., the vertical) and form an angle of less than or equal to 10 degrees (≤10°), or less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). The angle here is not limited to integer angles, and can be any angle within a limited range, such as 0.09°, 1.3°, 2.5°, 3°, etc. In some embodiments, the two first cutting wheels arranged vertically above and below the first cutting saw form a first cutting wire saw, with the upper first cutting wheel in front in a first direction and the lower first cutting wheel in a first direction behind in a first direction, resulting in a first cutting wire saw that forms a positive deflection angle with the vertical. In some embodiments, the two first cutting wheels arranged vertically above and below the first cutting saw form a first cutting wire saw, with the upper first cutting wheel in a first direction behind in a first direction and the lower first cutting wheel in front in a first direction, resulting in a first cutting wire saw that forms a negative deflection angle with the vertical. The deflection angle (including positive and negative deflection angles) can be varied according to the cutting process requirements and the size specifications of the silicon rod. For example, the angle can be adjusted by changing the position of one or both of the two vertically arranged first cutting wheels associated with the first cutting wire saw.

[0072] In some embodiments, the first wire cutting unit further includes a first tension adjustment mechanism. During wire cutting, the tension of the cutting wire affects the yield and processing accuracy. The first tension adjustment mechanism detects and adjusts the tension so that the tension of the first cutting wire reaches a set threshold and remains at a constant value or within a certain range allowed by the constant value during cutting.

[0073] In the embodiment, the first tension adjustment mechanism is associated with the first transition wheel 133 or the first cutting wheel. The first transition wheel 133 in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while guiding and pulling the first cutting wire 134.

[0074] Tensioners are used to adjust the tension of the cutting wire, reducing the probability of wire breakage and thus reducing material consumption. The cutting wire plays a crucial role in cutting operations, but even the best wire has limitations in elongation and wear resistance. This means that the wire gradually thins during continuous operation until it eventually breaks. Therefore, modern wire EDM equipment generally incorporates a wire tension compensation mechanism to compensate for the wire's elongation during its reciprocating motion; the tensioner is one such mechanism.

[0075] In some embodiments, the first silicon rod cutting apparatus further includes: at least one first adjustment mechanism disposed in at least one first wire cutting unit, for driving a plurality of first cutting wheels in the first wire cutting unit to move in a direction perpendicular to the wheel surface. The first silicon rod cutting apparatus can realize the switching of the first cutting line between different cutting grooves of the first cutting wheel based on the adjustment mechanism, or adjust the position of the first cutting wire saw to change the cutting position (or processing specifications) relative to the silicon rod.

[0076] In some implementations, a first wire cutting unit in a first silicon rod cutting apparatus is used as an example. The first wire cutting unit includes multiple first cutting wheels and multiple first transition wheels. The carrier supporting the multiple first cutting wheels and first transition wheels is, for example, a first cutting mounting structure. A first adjusting mechanism can be used to drive the entire first cutting mounting structure to move along the perpendicular direction of the cutting wheel surface. The first transition wheels and the first cutting wheels move together along the perpendicular direction of the first cutting wheel surface (i.e., the transposition direction or the second direction Y-axis) following the first cutting mounting structure. In this state, the multiple first cutting wheels and the first transition wheels are relatively stationary; that is, the positional relationship between the first transition wheels and the first cutting wheels remains unchanged. At this time, the first adjusting mechanism is used to adjust the cutting position of at least one first wire saw in at least one first wire cutting unit relative to the silicon rod.

[0077] In some implementations, each first cutting wheel has at least two first cutting grooves, which are parallel to each other and have a cutting offset perpendicular to the wheel surface. When the first adjusting mechanism drives the plurality of first cutting wheels in the first wire cutting unit to move relative to the first cutting mounting structure, the position of the grooves around the first cutting wire on the first cutting wheel can be changed. In some implementations, the plurality of first cutting wheels in the first wire cutting unit may be connected to a bracket, wherein the bracket is movably disposed on the first cutting mounting structure and driven by the first adjusting mechanism to move along the perpendicular direction of the wheel surface.

[0078] When at least one first adjustment mechanism is used to change the cutting groove of the first cutting line wound around multiple first cutting wheels in at least one first wire cutting unit, in a practical scenario, the first cutting grooves corresponding to the cutting lines before and after the groove change can be predetermined. For example, before the groove change, the position of the first cutting line is the first cutting groove a1, and after the groove change, the first cutting line is wound around the first cutting groove a2. The displacement amount that the first adjustment mechanism drives the multiple first cutting wheels in the first wire cutting unit to move is determined based on the cutting offset between the first cutting groove a1 and the first cutting groove a2. That is, the displacement amount is set as the first cutting line. The cutting offset between slot a1 and the first cutting line slot a2 can be used to change the first cutting line from the first cutting line slot a1 to the first cutting line slot a2. It should be noted that at least one first adjustment mechanism drives multiple first cutting wheels in the first wire cutting unit to move in the direction perpendicular to the surface of the first cutting wheel, which is the direction from the cutting line slot a2 to the cutting line slot a1. After the slot is changed, the cutting position of the first cutting wire saw in space remains unchanged, thus eliminating the need for further calibration of the position of the first cutting wheel or other components. The silicon rod can be cut according to the preset cutting amount, which simplifies the slot changing process.

[0079] To further illustrate how at least one first adjustment mechanism enables the movement of multiple first cutting wheels in the first wire cutting unit along a direction perpendicular to the wheel surface, this application discloses the following embodiments. The specific form of the at least one first adjustment mechanism can vary depending on the number of first wire cutting units in the first silicon rod cutting apparatus.

[0080] In some embodiments, the first silicon rod cutting apparatus includes a single-wire cutting unit, which is a first wire cutting unit. The first pitch adjustment mechanism includes: a lead screw, which is arranged in an orthogonal direction to the surface of the first cutting wheel and threadedly connected to the single-wire cutting unit; and a lead screw drive source for driving the lead screw to rotate.

[0081] The single-wire cutting unit in the first silicon rod cutting device includes multiple first cutting wheels, and a first cutting wire is wound around the multiple first cutting wheels to form at least one first cutting wire saw. The lead screw of the first adjustment mechanism has a distal end and a proximal end. In a specific implementation, for example, the proximal end of the lead screw can be connected to a lead screw drive source and rotated under the drive of the lead screw drive source. The distal end of the lead screw is threaded to the first single-wire cutting unit. Through the connection method of the two ends of the lead screw, the lead screw can rotate based on the transmission of the lead screw drive source, and the rotation of the lead screw is converted into axial displacement through the threaded connection. The axial displacement direction is the setting direction of the lead screw, that is, the orthogonal direction of the cutting wheel surface. By driving the lead screw to rotate through the lead screw drive source in the first adjustment mechanism, the displacement of the single-wire cutting unit in the orthogonal direction of the first cutting wheel surface can be realized. Different rotation directions of the lead screw can realize the forward or backward movement of the first cutting wheel of the single-wire cutting unit in the orthogonal direction of the first cutting wheel surface.

[0082] In some embodiments, the first silicon rod cutting device includes a single-wire cutting unit, which is a first wire cutting unit. The first adjustment mechanism includes: a telescopic member, arranged along the orthogonal direction of the first cutting wheel surface and associated with the single-wire cutting unit; and a telescopic member drive source for driving the telescopic member to extend and retract along the orthogonal direction of the first cutting wheel surface. Here, the telescopic member can be configured as a rod structure, with the rod extending in the orthogonal direction of the first cutting wheel surface. Driven by the telescopic member drive source, the telescopic member can extend and retract along its extension direction. One end of the telescopic member can be connected to the telescopic member drive source, and the extendable free end is associated with the single-wire cutting unit, thus driving the first cutting wheel of the single-wire cutting unit to move in the orthogonal direction of the first cutting wheel surface under the action of the telescopic member drive source. The telescopic member can be, for example, an electric telescopic rod, or a connecting rod connected to a cylinder, in which case the cylinder can serve as the telescopic member drive source; this application does not impose any limitations. The telescopic rod can be connected to the single-wire cutting unit via a straight connection or an indirect connection. For example, it can be directly connected to the first cutting mounting structure of the single-wire cutting unit, or indirectly connected to the first single-wire cutting unit via a support or bearing. It should be understood that the extension or retraction of the telescopic member corresponds to the forward or backward movement of the single-wire cutting unit along the orthogonal direction of the first cutting wheel surface.

[0083] In some embodiments, the association can be achieved by one or more of engagement, screwing, bonding, and welding. For example, in the above embodiments, the telescopic rod can be associated with the first wire cutting unit by one or more of engagement, screwing, bonding, and welding. Of course, the method of association is not limited to this, but is intended to achieve transmission in the second direction.

[0084] In some embodiments, the first silicon rod cutting device includes a single-wire cutting unit, which is a single wire cutting unit. The first pitch adjustment mechanism includes: a rack disposed in the first single-wire cutting unit along the orthogonal direction of the first cutting wheel surface; a transmission gear meshing with the rack; and a gear drive source for driving the transmission gear to rotate. The transmission gear rotates under the drive of the gear drive source, and the rack meshing with the transmission gear moves accordingly along the rack's direction. In this example, by engaging the rack with the transmission gear, the rotational motion driven by the gear drive source can be converted into linear transport along the rack direction. Since the rack is disposed in the first single-wire cutting unit along the orthogonal direction of the first cutting wheel surface, it can drive the first cutting wheel of the single-wire cutting unit to move along the orthogonal direction of the first cutting wheel surface. Simultaneously, by controlling the switching of the rotation direction of the transmission gear by the gear drive source, the multiple first cutting wheels of the single-wire cutting unit can move forward or backward along the orthogonal direction of the first cutting wheel surface.

[0085] In some embodiments, such as Figure 5 As shown, the first silicon rod cutting device includes two first wire cutting units arranged in parallel and opposite directions. At least one of the two first wire cutting units can be driven to move in the orthogonal direction of the first cutting wheel surface by at least one pitch adjustment mechanism, which is used to adjust the wire cutting saw spacing between the first cutting wire saws in the two first wire cutting units, or to change the cutting wire grooves of the first cutting wires wound around the multiple first cutting wheels in a certain first wire cutting unit.

[0086] The first silicon rod transfer device includes a first edge-skin anti-splitting device, which cooperates with the first silicon rod transfer device to clamp the end face of the silicon rod during the first cutting operation to prevent edge splitting. In some embodiments, the first edge-splitting anti-splitting device includes a clamping support and an edge-splitting clamp. Figure 5 and Figure 6 In the embodiment shown, the first edge-skin anti-splitting device 16 includes a clamping support 161 and an edge-skin clamp 162.

[0087] In some embodiments, the clamping support of the first edge anti-splitting device is associated with the first bearing platform of the first silicon rod transfer device, that is, the clamping support of the first edge anti-splitting device and the first bearing platform of the first silicon rod transfer device can move forward and backward together.

[0088] The edge clamp is mounted on a clamping support. In some embodiments, the edge clamp includes a clamping base, at least one pair of end face chucks, and a chuck drive mechanism. Figure 6 In the embodiment shown, the edge clamp 162 includes a clamp base 1621, a pair of end face clamps 1622 arranged opposite each other along the clamping direction, and a clamp drive mechanism.

[0089] A chuck driving mechanism is used to drive at least one end face chuck of at least one pair of end face chucks to move along the clamping direction to adjust the clamping distance between the at least one pair of end face chucks. In some embodiments, the chuck driving mechanism includes: a chuck moving guide rail arranged along the clamping direction; and a chuck driving unit for driving at least one end face chuck of at least one pair of end face chucks to move along the chuck moving guide rail.

[0090] In some embodiments, a chuck moving guide rail may be provided between the first end face chuck and the second end face chuck in at least one pair of end face chucks. For example... Figure 6 As shown, a moving guide assembly is provided between the first end face chuck and the second end face chuck in at least one pair of end face chucks. The moving guide assembly includes one or more moving guide rods or moving guide beams 1623, and a moving guide rail is provided on the moving guide rods or moving guide beams 1623.

[0091] In some embodiments, the chuck drive unit includes at least one chuck telescopic assembly. For example... Figure 6 As shown, the chuck telescopic assembly includes a chuck telescopic rod and a chuck telescopic cylinder. The chuck telescopic rod is arranged along the clamping direction and associated with a corresponding end-face chuck. The chuck telescopic cylinder is associated with the chuck telescopic rod. In some embodiments, the chuck driving mechanism is used to drive two end-face chucks in a pair to move towards each other or away from each other along the clamping direction. The chuck driving mechanism includes a pair of chuck telescopic assemblies, wherein each chuck telescopic assembly corresponds to one end-face chuck. The chuck telescopic rod in the chuck telescopic assembly is arranged along the clamping direction and associated with a corresponding end-face chuck. The chuck telescopic cylinder in the chuck telescopic assembly is associated with the chuck telescopic rod. By controlling the corresponding chuck telescopic rod to retract or extend using the chuck telescopic cylinder in the pair of chuck telescopic assemblies, the pair of end-face chucks can be driven to move towards each other or away from each other along the moving guide rail on the moving guide rod or moving guide beam. In some embodiments, the chuck driving mechanism is used to drive one of a pair of end-face chucks to move towards or away from the other end-face chuck along the clamping direction. The chuck driving mechanism includes a chuck telescopic assembly corresponding to the end-face chuck to be moved. A chuck telescopic rod in the chuck telescopic assembly is arranged along the clamping direction and associated with the corresponding end-face chuck. A chuck telescopic cylinder in the chuck telescopic assembly is associated with the chuck telescopic rod. By controlling the corresponding chuck telescopic rod to retract or extend using the chuck telescopic cylinder in the chuck telescopic assembly, the corresponding end-face chuck can be moved along a moving guide rail on a moving guide rod or moving guide beam towards or away from the other end-face chuck.

[0092] Please see Figure 7 Displayed as Figure 6 A schematic diagram of the structure of the edge clamp in one embodiment. Figure 6 and Figure 7In the embodiment shown, the end face chuck includes a clamping base 1624, a silicon rod pressing member 1625 and an edge pressing member 1626 disposed on the clamping base 1624, and an edge clamping reinforcement member 1627 that moves forward and backward relative to the clamping base 1624 along the clamping direction.

[0093] The clamping base 1624 serves as the main body of the end face chuck, providing a foundation for the silicon ingot pressing member 1625, the edge pressing member 1626, and the edge clamping reinforcement 1627. In some embodiments, the clamping base may be, for example, a clamping substrate, the size of which is adapted to the end face of the silicon ingot and the edge to be cut; that is, the clamping substrate must cover at least a portion of the silicon ingot body and a portion of the edge. The clamping substrate must cover a portion of the silicon ingot body so that the silicon ingot pressing member disposed thereon can act on the silicon ingot body. The clamping substrate must also cover a portion of the edge so that the edge pressing member and the edge clamping reinforcement disposed thereon can act on the edge.

[0094] In such Figure 7 In the illustrated embodiment, in the end face chuck, the silicon rod pressing member 1625 includes a silicon rod pressing screw disposed on the clamping substrate 1624, and the edge pressing member 1626 includes an edge pressing screw disposed on the clamping substrate 1624. The number of silicon rod pressing screws and the number of edge pressing screws can be one or more. In practical applications, the silicon rod pressing screw is used to press the silicon rod body, and the edge pressing screw is used to press the edge to be cut. With the silicon rod pressing screw pressing the silicon rod body and the edge pressing screw pressing the edge to be cut, relative stability between the silicon rod body and the edge can be ensured. This avoids edge chipping or other phenomena that occur when the wire saw in the wire cutting unit passes through the silicon rod to completely remove it, causing the edge to fall off or the edge to shift from the silicon rod body.

[0095] It is easy to see that in some cases, the end face of the silicon rod is not an ideal flat surface, and one of the silicon rod pressing component and the edge pressing component may not be able to effectively abut and press against the corresponding silicon rod body or edge.

[0096] To ensure that the silicon rod pressing elements and edge pressing elements arranged on the clamping substrate can adapt to the end face of the silicon rod to achieve effective pressing, in some embodiments, the end face chuck also includes an offset fine-tuning structure for adjusting the position of the clamping substrate. Using the offset fine-tuning structure, the position of the clamping substrate can be locally adjusted, thereby changing the position of the silicon rod pressing elements and edge pressing elements arranged on the clamping substrate. In such cases... Figure 7 In the embodiment shown, the end face chuck also includes a biasing fine-tuning structure for adjusting the clamping substrate 1624. The biasing fine-tuning structure can be used to locally adjust the position of the clamping substrate 1624, thereby changing the position of the silicon rod pressing screw and the edge pressing screw arranged on the clamping substrate 1624.

[0097] In some embodiments, the biasing fine-tuning structure employs a ball-head structure or a similar structure, and the substrate is clamped via the ball-head structure. For example... Figure 7 As shown, the clamping substrate 1624, serving as the clamping base, is mounted on the mounting structure via a ball-head structure 1629. Thus, the clamping substrate 1624 can be finely adjusted relative to the mounting structure via the ball-head structure 1629, changing the position of the clamping substrate 1624 and the silicon rod pressing screws 1625 and edge pressing screws 1626 arranged thereon, thereby adapting to the end face of the silicon rod, even if the end face of the silicon rod has a certain degree of unevenness. In some embodiments, the ball-head structure is a spherical steel ball, which is embedded in a receiving cavity and has a small portion protruding to contact the clamping substrate. In some embodiments, a ball head or a hemispherical head is used, which is connected to the clamping substrate via a connecting rod and is embedded in a receiving cavity.

[0098] In some embodiments, the offset fine-tuning structure employs a hinged structure, and the clamping substrate is configured via the hinged structure. For example, the clamping substrate is associated with the mounting structure via the hinged structure, allowing it to offset relative to the mounting structure to a certain extent.

[0099] Furthermore, in some embodiments, in the end face chuck, the silicon rod pressing member includes a silicon rod pressing elastic member disposed on the clamping base, and the edge pressing member includes an edge pressing elastic member disposed on the clamping base. For example, in some embodiments, the silicon rod pressing elastic member includes a silicon rod push rod sleeved with a compression spring; the edge pressing elastic member includes an edge push rod sleeved with a compression spring. In some embodiments, the silicon rod pressing elastic member includes a silicon rod push block with a compression spring at its rear end; the edge pressing elastic member includes an edge push block with a compression spring at its rear end.

[0100] The end-face chuck also includes an edge clamping reinforcement, which can move forward and backward relative to the clamping substrate along the clamping direction. When the edge clamping reinforcement moves forward relative to the clamping substrate, it can provide a strong clamping force on the corresponding edge. Generally, the clamping force applied to the edge by the edge clamping reinforcement is greater than the top pressure applied to the silicon rod body by the silicon rod top pressure member and the top pressure applied to the edge by the edge top pressure member.

[0101] In some embodiments, the edge clamping reinforcement includes a telescopic rod or telescopic block that controls the forward and backward movement relative to the clamping substrate. In such... Figure 7In the illustrated embodiment, the edge clamping reinforcement includes a telescopic rod or telescopic block 1627 and a telescopic drive source 1628, which drives the telescopic rod or telescopic block 1627 to move forward and backward relative to the clamping base plate 1624. In some embodiments, the clamping base plate 1624 has through holes. The telescopic drive source 1628 and the telescopic rod or telescopic block 1627 are disposed on the mounting structure. The telescopic drive source 1628 can drive the telescopic rod or telescopic block 1627 to extend out of the clamping base plate 1624 and press against the corresponding edge, or drive the telescopic rod or telescopic block 1627 to retract into the clamping base plate 1624. The telescopic drive source may be, for example, a telescopic cylinder.

[0102] The end face chuck can still be modified in other embodiments. In some embodiments, the end face chuck includes: a first clamping base and a second clamping base, wherein a silicon rod pressing member is provided on the first clamping base, and an edge pressing member and an edge clamping reinforcement member that moves forward and backward relative to the second clamping base along the clamping direction are provided on the second clamping base.

[0103] In some embodiments, the first clamping base may be, for example, a clamping substrate, the size of which is adapted to the end face of the silicon rod body, that is, the first clamping substrate shall cover at least a portion of the silicon rod body, such that a silicon rod pressing member disposed thereon can act on the silicon rod body. The second clamping base may be, for example, a clamping substrate, the size of which is adapted to the end face of the edge skin to be cut, that is, the first clamping substrate shall cover at least a portion of the edge skin, such that an edge skin pressing member disposed thereon can act on the edge skin.

[0104] In the end-face chuck, the silicon rod pressing component includes silicon rod pressing screws disposed on the first clamping substrate, and the number of silicon rod pressing screws can be one or more. The edge pressing component includes edge pressing screws disposed on the second clamping substrate, and the number of edge pressing screws can be one or more. In practical applications, the silicon rod pressing screws are used to press the silicon rod body, and the edge pressing screws are used to press the edge to be cut. When the silicon rod pressing screws press the silicon rod body and the edge pressing screws press the edge to be cut, it can ensure that the silicon rod body and the edge remain relatively stable. This can prevent the edge from falling off or the edge from shifting from the silicon rod body and causing chipping when the wire saw in the wire cutting unit passes through the silicon rod to completely cut it off.

[0105] Furthermore, in some embodiments, in the end face chuck, the silicon rod pressing member includes a silicon rod pressing elastic member disposed on the first clamping base, and the edge pressing member includes an edge pressing elastic member disposed on the second clamping base. For example, in some embodiments, the silicon rod pressing elastic member includes a silicon rod push rod sleeved with a compression spring; the edge pressing elastic member includes an edge push rod sleeved with a compression spring. In some embodiments, the silicon rod pressing elastic member includes a silicon rod push block with a compression spring at its rear end; the edge pressing elastic member includes an edge push block with a compression spring at its rear end.

[0106] The end face chuck also includes an edge clamping reinforcement, which can move forward and backward relative to the second clamping base along the clamping direction. When the edge clamping reinforcement moves forward relative to the second clamping base, it can provide a strong clamping force to the corresponding edge. Generally, the clamping force applied to the edge by the edge clamping reinforcement is greater than the top pressure applied to the silicon rod body by the silicon rod top pressure member and the top pressure applied to the edge by the edge top pressure member.

[0107] In some embodiments, the edge clamping reinforcement includes a telescopic rod or telescopic block that is controlled to move forward and backward relative to the second clamping base. For example, the edge clamping reinforcement includes a telescopic rod or telescopic block and a telescopic drive source, which drives the telescopic rod or telescopic block to move forward and backward relative to the second clamping base. In some embodiments, the second clamping base has a through hole, and the telescopic drive source and the telescopic rod or telescopic block are disposed on a mounting structure. The telescopic drive source can drive the telescopic rod or telescopic block to extend out of the second clamping base and press against the corresponding edge, or drive the telescopic rod or telescopic block to retract into the second clamping base. The telescopic drive source may, for example, be a telescopic cylinder.

[0108] Thus, when performing the first cutting operation on the silicon rod using the first silicon rod cutting device, the silicon rod to be cut is carried by the first silicon rod transfer device, and the chuck driving mechanism in the first edge anti-chipping device drives at least one of the at least one pair of end face chucks to move along the clamping direction, so that the at least one pair of end face chucks clamps both ends of the silicon rod. The silicon rod pressing member in the end face chuck presses against the main body of the silicon rod, and the edge pressing member in the end face chuck presses against the edge to be cut in the silicon rod. The edge clamping reinforcement is in a retracted state (in the retracted state, the edge clamping reinforcement is recessed into the clamping base, or protrudes from the clamping base, but its protrusion height relative to the clamping base is less than that of the silicon rod pressing component and the edge pressing component relative to the clamping base), keeping the edge skin relatively stationary with respect to the silicon rod body. This prevents the edge skin from falling off or shifting from the silicon rod body, which could lead to chipping, when the wire saw in the wire cutting unit passes through the silicon rod to be cut for complete removal. After the edge skin is cut, the edge clamping reinforcement in the drive end face chuck extends relative to the clamping base and presses against the cut edge skin. The clamping force applied to the edge skin by the edge clamping reinforcement is greater than the pressing force applied to the silicon rod body by the silicon rod pressing component and the pressing force applied to the edge skin by the edge pressing component. At this time, at least one pair of end face chucks can be operated to move the cut edge skin.

[0109] In this application, the first edge-skin anti-scratching device may further include an edge-skin clamping mechanism for driving the edge-skin clamp to move forward and backward in the forward and backward direction.

[0110] In an embodiment where the end face chuck includes a clamping base and an edge skin pressing member disposed on the clamping base, after the edge skin is cut, the edge skin clamp is driven to exit in the advancing and retreating direction by the edge skin clamp advancing and retreating mechanism. The pressing force applied to the edge skin by the pressing member can drive the clamped edge skin to detach from the silicon rod body.

[0111] In an embodiment where the end face chuck includes a clamping base, a silicon rod pressing member and an edge pressing member disposed on the clamping base, and an edge clamping reinforcement member that moves forward and backward relative to the clamping base in the clamping direction, after the edge is cut, the edge clamping reinforcement member in the end face chuck is driven to extend relative to the clamping base and press against the cut edge. At this time, the edge clamp is driven to withdraw in the forward and backward direction by the edge clamping mechanism. Taking advantage of the fact that the clamping force applied to the edge by the edge clamping reinforcement member is greater than the pressing force applied to the silicon rod body by the silicon rod pressing member and the pressing force applied to the edge by the edge pressing member, the clamped edge can be disengaged from the silicon rod body.

[0112] In some embodiments, the edge leather clamp advance / retreat mechanism includes: a clamp advance / retreat guide rail, arranged along the advance / retreat direction; and an edge leather clamp advance / retreat unit for driving the edge leather clamp to move along the clamp advance / retreat guide rail. Figure 6In the embodiment shown, the edge clamp advance and retreat mechanism 163 includes: clamp advance and retreat guide rail 1631 and edge clamp advance and retreat unit.

[0113] In some embodiments, the edge clamp advance / retreat unit includes: a clamping seat telescopic rod and a clamping seat telescopic cylinder. The clamping seat telescopic rod is arranged along the advance / retreat direction and associated with the clamping seat of the edge clamp, and the clamping seat telescopic cylinder is associated with the clamping seat telescopic rod. Figure 6 In the illustrated embodiment, the edge clamp advance / retreat unit includes a clamping seat telescopic rod 1633 and a clamping seat telescopic cylinder 1635. The clamping seat telescopic rod 1633 is arranged along the advance / retreat direction and associated with the clamping seat 1621 of the edge clamp. The clamping seat telescopic cylinder 1635 can be mounted on a mounting structure and associated with the clamping seat telescopic rod 1633. In some embodiments, the clamping seat telescopic cylinder 1635 drives the clamping seat telescopic rod to extend, driving the edge clamp 162 to move towards the first silicon rod transfer device, allowing the edge clamp 162 to clamp the end face of the silicon rod. In some embodiments, the clamping seat telescopic cylinder 1635 drives the clamping seat telescopic rod to retract, driving the edge clamp 162 to move away from the first silicon rod transfer device, causing the edge clamp 162 to pull the clamped edge out to detach from the silicon rod body.

[0114] In some embodiments, the edge clamp advance / retreat unit includes: an edge clamp advance / retreat mechanism comprising: a clamping rack, arranged along the advance / retreat direction and associated with the clamping seat of the edge clamp; a clamping gear, meshing with the clamping rack; and a gear drive source, associated with the clamping gear, for driving the clamping gear to rotate so that the meshing edge clamp moves along the advance / retreat direction. The gear drive source may be, for example, a servo motor. In practical applications, the servo motor, acting as the gear drive source, rotates forward, driving the associated clamping gear to rotate forward, causing the edge clamp associated with the clamping gear to move towards the silicon rod transfer device on the meshing clamping rack, allowing the edge clamp to hold the end face of the silicon rod. Conversely, the servo motor, acting as the gear drive source, rotates in the opposite direction, driving the associated clamping gear to rotate in the opposite direction, causing the edge clamp associated with the clamping gear to move away from the silicon rod transfer device on the meshing clamping rack, causing the edge clamp to pull the clamped edge out to disengage from the silicon rod body.

[0115] In some embodiments, the edge clamp advance / retreat unit includes: an exit screw and a screw drive source. The exit screw is arranged along the advance / retreat direction and associated with the clamping seat of the edge clamp, and the screw drive source is associated with the exit screw. The screw drive source can be, for example, a servo motor. In practical applications, the servo motor, acting as the screw drive source, rotates forward, causing the exit screw to rotate forward, thus moving the edge clamp associated with the exit screw toward the silicon rod transfer device, allowing the edge clamp to hold the end face of the silicon rod. Conversely, the servo motor, acting as the screw drive source, rotates in the opposite direction, causing the exit screw to rotate in the opposite direction, causing the edge clamp associated with the exit screw to move away from the silicon rod transfer device, thus causing the edge clamp to pull the clamped edge out to detach from the silicon rod body.

[0116] In this application, the first edge-stripping prevention device may further include a clamping lifting mechanism for driving the edge-stripping clamp to move vertically up and down. In some embodiments, the edge-stripping clamp moves vertically upward or downward via the clamping lifting mechanism to accommodate the size specifications of the silicon rod being transferred. For example, if the size of the silicon rod to be cut is large, the edge-stripping clamp is driven to move vertically upward via the clamping lifting mechanism; and if the size of the silicon rod to be cut is small, the edge-stripping clamp is driven to move vertically downward via the clamping lifting mechanism.

[0117] In some embodiments, the clamp lifting mechanism includes a clamp lifting guide rail and a clamp lifting unit, wherein the clamp lifting guide rail is arranged vertically. The clamp lifting unit is used to drive the edge clamp to move up and down along the clamp lifting guide rail. Figure 6 In the embodiment shown, the clamp lifting mechanism 164 includes a clamp lifting guide rail 1641 and a clamp lifting unit.

[0118] In some embodiments, the edge clamp lifting unit includes: a lifting screw and a screw drive source, the lifting screw being arranged vertically and associated with the clamp seat of the edge clamp, and the screw drive source being associated with the lifting screw. Figure 6 In the illustrated embodiment, the edge clamp lifting unit includes a lifting screw 1643 and a screw drive source. The lifting screw 1643 is arranged vertically and associated with the mounting structure of the clamp seat on which the edge clamp is mounted. The screw drive source is associated with the lifting screw 1643. The screw drive source can be, for example, a servo motor. In practical applications, the servo motor, acting as the screw drive source, rotates forward, driving the lifting screw to rotate forward, causing the edge clamp associated with the lifting screw to move upward. Conversely, the servo motor, acting as the screw drive source, rotates in the opposite direction, driving the lifting screw to rotate in the opposite direction, causing the edge clamp associated with the lifting screw to move downward.

[0119] In some embodiments, the clamp lifting unit includes a lifting rack, a lifting gear, and a gear drive source. The lifting rack is arranged vertically and associated with the clamping seat of the edge clamp. The lifting gear meshes with the lifting rack. The gear drive source is associated with the lifting gear and drives the lifting gear to rotate, causing the meshing edge clamp to move vertically up and down. The gear drive source may be, for example, a servo motor. In practical applications, the servo motor, acting as the gear drive source, rotates forward, driving the associated lifting gear to rotate forward, causing the edge clamp associated with the clamping seat gear to move upward on the meshing clamping rack. Conversely, the servo motor, acting as the gear drive source, rotates in the opposite direction, driving the associated clamping seat gear to rotate in the opposite direction, causing the edge clamp associated with the clamping seat gear to move downward on the meshing clamping rack.

[0120] Thus, when the application Figure 6 When the first edge-skin anti-splitting device 16 is shown, the silicon rod is horizontally placed on the silicon rod carrying platform of the silicon rod transfer device; the clamp lifting mechanism 164 in the first edge-skin anti-splitting device 16 drives the edge-skin clamp 162 to move vertically to adjust its position; the edge-skin clamp advancing and retreating mechanism 163 in the first edge-skin anti-splitting device 16 drives the edge-skin clamp to move forward and approach the silicon rod in the advancing and retreating direction; the chuck driving mechanism 162 in the first edge-skin anti-splitting device 16 drives at least one of the at least one pair of end-face chucks to move in the clamping direction until the silicon rod pressing member on the end-face chuck presses against the silicon rod body and the edge-skin pressing member on the end-face chuck presses against the edge to be cut (see details). Figure 8 (See the schematic diagram shown). Afterwards, the silicon rod is square-cut by a silicon rod cutting device to form the silicon rod body and edge skin (see details...). Figure 9 (See the schematic diagram shown). After the edge skin 101 is cut, the edge skin clamping reinforcement in the drive end face chuck extends relative to the clamping base and presses against the cut edge skin 101. At this time, the edge skin clamp 162 is driven to retract in the forward and backward direction by the edge skin clamping mechanism 163. Taking advantage of the fact that the clamping force applied to the edge skin by the edge skin clamping reinforcement is greater than the top pressure applied to the silicon rod body by the silicon rod top pressure member and the top pressure applied to the edge skin by the edge skin top pressure member, the clamped edge skin 101 can be disengaged from the silicon rod body (see details). Figure 10 The diagram shows the state.

[0121] In this application, the first edge-breaking prevention device also includes an edge-feeding conveying mechanism, which is connected to the edge-feeding clamping advance and retreat mechanism.

[0122] In some embodiments, the edge skin feeding and conveying mechanism may include an edge skin bearing structure and a conveying drive mechanism. For example... Figure 5 As shown, the edge skin feeding mechanism may include an edge skin bearing structure 167 and a conveying drive mechanism 168.

[0123] The edge skin support structure 167 is used to support the edge skin. First, the edge skin held by the edge skin clamp is withdrawn in the forward / backward direction using the edge skin clamping mechanism, thereby detaching the edge skin from the silicon rod body. Then, the chuck drive mechanism in the edge skin clamp drives the chuck to move, releasing the clamped edge skin and allowing it to fall onto the edge skin support structure. In some embodiments, the edge skin support structure may be, for example, an edge skin placement groove. The edge skin placement groove may, for example, be U-shaped.

[0124] In some embodiments, a conveying drive mechanism is used to move the drive edge bearing structure along the transfer direction to move it between a first loading / unloading area and a first cutting area. In such... Figure 5 In the illustrated embodiment, the edge skin feeding mechanism includes two edge skin support structures 167 and a conveying drive mechanism 168. The conveying drive mechanism 168 is associated with the two edge skin support structures 167 and is used to drive the two edge skin support structures 167 to move between a first loading / unloading area and a first cutting area. In some embodiments, the conveying drive mechanism 168 may be, for example, a chain conveyor mechanism. Of course, in the edge skin feeding conveying mechanism, a conveying drive mechanism can be configured for each edge skin support structure, and the conveying drive mechanism drives the corresponding edge skin support structure. Taking a chain conveyor as an example, the conveyor drive mechanism includes a ring chain, a chain drive source, and connectors. The ring chain is a closed-loop chain that is wound around multiple movable gears to form a preset shape, such as an inverted triangle, rectangle, or trapezoid. The edge bearing structure is connected to the ring chain through the connectors. The chain drive source can be, for example, a servo motor, which is connected to one of the movable gears. For example, the output shaft of the servo motor is connected to the gear shaft of the movable gear. When the ring chain is driven by the servo motor, the edge bearing structure and the edge it carries can move in the transfer direction through the connectors. In practical applications, when the servo motor operates, it drives the associated movable gear to rotate forward (or backward). The forward (or backward) rotating movable gear drives the meshing annular chain to move forward (or backward). The forward (or backward) moving annular chain can drive the edge-bearing structure to move from the first loading / unloading area to the first cutting area through the connector. Conversely, when the servo motor operates, it drives the associated movable gear to rotate backward (or forward). The reverse (or forward) rotating movable gear drives the meshing annular chain to move backward (or forward). The reverse (or forward) moving annular chain can drive the edge-bearing structure and the edge it carries to move from the first cutting area to the first loading / unloading area through the connector.

[0125] In some embodiments, a conveying drive mechanism is used to convey the edge skin from the edge skin bearing structure.

[0126] In this application, the edge skin feeding and conveying mechanism further includes an edge skin flipping mechanism for driving the edge skin supporting structure to flip. Each edge skin supporting structure is equipped with an edge skin flipping mechanism, which drives the corresponding edge skin supporting structure and the edge skin it carries to flip. In some embodiments, please refer to... Figure 11 and Figure 12 In such Figure 11 and Figure 12 In the illustrated embodiment, the edge skin flipping mechanism includes a pivot shaft and a telescopic assembly. The telescopic assembly includes a telescopic rod 1691 and a telescopic cylinder 1692. The edge skin bearing structure 167 is pivotally mounted via the pivot shaft. One end of the telescopic rod 1691 is associated with the corresponding edge skin bearing structure 167, and the other end of the telescopic rod 1691 is associated with the telescopic cylinder 1692. In practical applications, the telescopic cylinder 1692 drives the telescopic rod 1691 to retract, causing the telescopic rod 1691 to pull the edge skin bearing structure 167 to flip vertically via the pivot shaft and position it vertically. The telescopic cylinder 1692 also drives the telescopic rod 1691 to extend, causing the telescopic rod 1691 to push the edge skin bearing structure 167 to flip vertically away via the pivot shaft and position it flat or at an angle. This allows the edge skin carried by the edge skin bearing structure 167 to lie flat or at an angle, facilitating subsequent unloading of the edge skin.

[0127] When performing the first silicon rod cutting operation using the first silicon rod cutting device in the small-size rectangular rod cutting and grinding integrated equipment of this application, the silicon rod to be cut is placed horizontally on the first silicon rod transfer device located at the first loading and unloading area; the first silicon rod carrying device and the silicon rod it carries are driven to transfer from the first loading and unloading area to the first cutting area along the transfer direction; the edge clamp is driven to move forward along the forward and backward direction to the silicon rod by the edge clamp advance mechanism; the edge clamp of the first edge anti-chipping device is driven to clamp the silicon rod to be cut; at this time, the two first cutting wire saws arranged in parallel in the first silicon rod cutting device are located between the first edge clamp and the silicon rod; the first silicon rod transfer device is driven to carry the silicon rod forward towards the first cutting area along the transfer direction; the two first cutting wire saws arranged in parallel in the first silicon rod cutting device move relative to each other along the transfer direction so that the cross-section is circular by the two first cutting wire saws arranged in parallel in the first silicon rod cutting device. The silicon rod is subjected to a first cutting operation, resulting in the removal of two edge skins to form two parallel first side cut surfaces. The edge skin clamping mechanism in the first edge skin anti-breakage device is used to retract the edge skin clamp along the retraction direction, thereby detaching the clamped edge skin from the silicon rod body. A clamp lifting mechanism lowers the edge skin clamp and the edge skin it holds, releasing the clamp and placing the edge skin onto the edge skin support structure. A conveying drive mechanism moves the edge skin support structure from the first cutting area to the first loading / unloading area along the transfer direction. A edge skin flipping mechanism flips the edge skin support structure and the edge skin it carries, unloading the flipped edge skin. Finally, the first silicon rod support device and the silicon rod body it carries are moved along the transfer direction from the first cutting area to the first loading / unloading area, completing the first cutting operation of the silicon rod.

[0128] The second cutting station includes a second loading / unloading area and a second cutting area. A second silicon rod transfer device is configured on the second cutting station. The second silicon rod transfer device is used to carry silicon rods with two first side cuts and transfer them between the second loading / unloading area and the second cutting area along the transfer direction. The second silicon rod cutting device is located in the second cutting area. The second silicon rod cutting device is equipped with at least one second cutting wire saw and at least one third cutting wire saw. The at least one second cutting wire saw and the at least one third cutting wire saw are located in the vertical plane and are arranged along the vertical or at an angle to the vertical. The second silicon rod cutting device and the second silicon rod transfer device move relative to each other along the transfer direction so that the second cutting wire saw and the third cutting wire saw can perform a second cutting operation on the silicon rod with two first side cuts to obtain at least two half rods with rectangular cross sections.

[0129] The second silicon rod transfer device is used to carry silicon rods along the transfer direction between the second loading / unloading area and the second cutting area of ​​the second cutting station. The silicon rod (having two first side cut surfaces) is placed horizontally on the second silicon rod transfer device and the axis of the silicon rod is consistent with the transfer direction, which is consistent with the first direction.

[0130] The second silicon rod cutting device is located at the second cutting station and is used to perform a second cutting operation on the silicon rod transferred by the second silicon rod at the second cutting area of ​​the second cutting station, so that the silicon rod is cut into at least two half rods with a rectangular cross section after forming two parallel second side cut surfaces and at least one cutting surface located between the two second side cut surfaces.

[0131] The second silicon rod cutting device includes at least one second wire cutting unit, which includes multiple second cutting wheels and a second cutting wire. The second cutting wire is sequentially wound around the multiple second cutting wheels to form at least one second wire saw. The second wire cutting unit moves relative to the second silicon rod transfer device and the silicon rod it carries at the second cutting station, and the at least one second wire saw performs a second cutting operation on the silicon rod carried by the second silicon rod transfer device. In some embodiments, the second cutting wire is wound in a loop between the second cutting wheels, where the ends are connected. In this case, the second cutting wire can also be referred to as a closed-loop cutting wire.

[0132] like Figure 1 As shown, the second silicon rod cutting device 15 includes two second wire cutting units 151 arranged in parallel. Each second wire cutting unit includes: a plurality of second cutting wheels and a second cutting line. The second cutting line is wound around the plurality of second cutting wheels to form at least one second wire saw. The second wire saw is arranged along the vertical direction or at an angle to the vertical direction.

[0133] Please see Figure 13 The diagram shows a schematic representation of the second silicon rod cutting device in one embodiment. Figure 13 In the illustrated embodiment, the second silicon rod cutting device 15 includes two second wire cutting units 151. Each second wire cutting unit 151 includes a plurality of second cutting wheels 152 and a second cutting wire 154. The second cutting wire is wound around the plurality of second cutting wheels 152 to form at least one second wire saw 155, wherein the second wire saw 155 is arranged vertically or at an angle to the vertical. Furthermore, the second wire cutting unit 151 may also include a second cutting mounting structure 150, on which the aforementioned plurality of second cutting wheels 152 are disposed.

[0134] In some embodiments, multiple second cutting wheels in the second wire cutting unit are connected to the second cutting mounting structure. Alternatively, multiple second cutting wheels are mounted on the second cutting mounting structure via a bracket, connecting plate, or mounting frame. The second cutting mounting structure serves as a carrier that associates multiple second cutting wheels in the second wire cutting unit with the second cutting frame or second cutting seat. The specific form of the second cutting mounting structure can be a beam, plate frame, bracket, etc., and this application does not impose any limitations.

[0135] In the small-size rectangular rod cutting and grinding integrated equipment of this application, the second wire saw in the second wire cutting unit of the second silicon rod cutting device is arranged along the vertical direction or at an angle to the vertical direction.

[0136] In the second wire cutting unit, the second cutting wheel is provided with at least one second cutting wire groove for winding the cutting wire. The second cutting wire groove can define the position of the second cutting wire, thereby controlling the cutting accuracy. Any second wire saw is formed between two opposing second cutting wheels after the second cutting wire is wound around it. The positions of the two second cutting wheels and the positional relationship between the second cutting wheels can be used to determine the direction of the second wire saw.

[0137] like Figure 13 As shown, in some embodiments, the second cutting mounting structure 150 is a rectangular frame, and the second cutting unit includes a plurality of second cutting wheels 152, for example, four second cutting wheels 152. The four second cutting wheels 152 are respectively located near the four corners of the second cutting mounting structure 150, and the wheel surface of each second cutting wheel 152 is located in a vertical plane (the vertical plane is composed of a first direction and a third direction). Two second cutting wheels 152 are in front (relatively closer to the second loading and unloading area) and arranged in parallel vertically, and the other two second cutting wheels 152 are in the back (relatively farther from the second loading area) and arranged in parallel vertically. The second cutting line 154 is wound around these four second cutting wheels 152 to form at least one second cutting wire saw 155 (for example, a second cutting wire saw 155 is formed between the two second cutting wheels 152 that are in front and arranged in parallel vertically). The second cutting wire saw 155 is arranged along a third direction (i.e., vertically). In addition, in order for the second wire saw 155 to effectively cut the silicon rod, the second wire saw 155 must interfere with the silicon rod in the vertical direction.

[0138] In some embodiments, the second cutting lines are wound around the respective second cutting wheels in an end-to-end manner to form a loop cutting line (also known as a closed-loop cutting line). Figure 13 In the embodiment shown, the second cutting line 154 is wound around the plurality of second cutting wheels 152 in a head-to-tail manner to form a ring cutting line (also known as a closed-loop cutting line).

[0139] In the second cutting unit, multiple second cutting wheels are wound around a circular cutting wire. In this example, the second silicon rod cutting device can eliminate the need for a wire storage spool. The circular cutting wire, driven by a cutting wire drive device, can maintain high-speed operation. Furthermore, the circular cutting wire can run in the same direction during the cutting operation. Thus, the second silicon rod cutting device can achieve high-precision second cutting operations, avoiding problems such as wavy cut surfaces caused by wire reversal or speed changes in existing cutting methods. Simultaneously, the circular cutting wire effectively reduces the total length of the cutting wire required for the second wire cutting unit, lowering production costs.

[0140] In some embodiments, the cutting wire drive device is a motor with a power output shaft connected to the second cutting wheel. Thus, the second cutting wire can be driven by the wound second cutting wheel to run along the winding direction. Of course, in specific implementations, the cutting wire drive device can also be other drive sources such as a hydraulic motor, as long as it drives the second cutting wire; this application does not impose any limitations.

[0141] The second wire cutting unit in this application may further include a second transition wheel, which is used to reverse or guide the second cutting line, or, alternatively, to adjust the tension of the second cutting line. The number of second transition wheels may be one or more, depending on the layout requirements.

[0142] The second transition wheel guides and pulls the second cutting wire while simultaneously acting as a tensioning wheel to adjust the tension of the second cutting wire. The tensioning wheel is used to adjust the tension of the second cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0143] like Figure 13 As shown, in the second wire cutting unit, the second cutting mounting structure 150 is a rectangular frame. Each second wire cutting unit 151 includes multiple second cutting wheels 152 and multiple second transition wheels 153. For example, two second cutting wheels 152 and two second transition wheels 153 are respectively located near the four corners of the second cutting mounting structure 150. The wheel surfaces of the two second cutting wheels 152 and the two second transition wheels 153 are located in the vertical plane. The two second cutting wheels 152 are arranged in front and parallel vertically, and the two second transition wheels 153 are arranged in the back and parallel vertically. The second cutting line 154 is wound around the two second cutting wheels 152 and the two second transition wheels 153 to form at least one second cutting wire saw 155 (for example, a second cutting wire saw 155 is formed between the two second cutting wheels 152). The at least one second cutting wire saw 155 is arranged vertically.

[0144] As before, the second cutting line 154 is wound around a plurality of second cutting wheels 152 or a plurality of second cutting wheels 152 and a plurality of second transition wheels 153 to form a second cutting line saw 155 between the two preceding second cutting wheels 152. Therefore, to adjust the line length of the second cutting line saw 155, the spacing between the two second cutting wheels 152 can be adjusted, which can be achieved by changing the position of at least one of the two second cutting wheels 152.

[0145] The second wire saw is located in the vertical plane and is arranged along the vertical direction or at an angle to the vertical direction. The silicon rod carried by the second silicon rod transfer device at the corresponding second cutting station is placed horizontally (the axis of the silicon rod is arranged along the transfer direction). Therefore, in order to cut the silicon rod, the length of the second wire saw is adapted to the size of the end face of the silicon rod. For example, the length of the second wire saw must be greater than or equal to the diameter of the silicon rod or the chord length at the position where the silicon rod is to be cut.

[0146] The direction of the second cutting wheel surface corresponds to the direction of the second cutting wire saw. It should be understood that the second cutting wheel surface is parallel to the plane where any of the second cutting wire grooves in the second cutting wheel are located. In order to control the cutting accuracy and the stability of the cutting process, the second cutting wire saw should be located in the plane where the second cutting wire groove is used to wind the second cutting wire. At the same time, during the cutting process, the direction of the force applied by the silicon rod to the second cutting wire should be parallel to the cutting wire groove, that is, the cutting wheel surface should be parallel to the cutting direction. The cutting direction in the second cutting operation is the direction of the silicon rod axis, that is, the transfer direction (i.e., the first direction X-axis).

[0147] The second silicon rod cutting device includes two parallel second wire cutting units, each with a second wire saw; therefore, the two second wire cutting units form two parallel wire saws. Figure 13 In the embodiment shown, the second silicon rod cutting device includes two second wire cutting units arranged in parallel along a second direction. Each second wire cutting unit has a second wire saw, which is arranged vertically. Thus, the two second wire saws belonging to the two second wire cutting units are both arranged vertically.

[0148] In fact, the second wire saw can still have other variations. In some embodiments, the second wire saw is arranged vertically, but this is not a limitation. In other embodiments, the position of the second wire saw can be located in the vertical plane and arranged at an angle to the vertical (i.e., the third direction). The vertical plane is formed by the first direction and the third direction, and the angle is less than or equal to 10 degrees (≤10°), or less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). That is, the wire cutting direction of the second wire saw can be located in the vertical plane with the third direction (i.e., the vertical) and form an angle of less than or equal to 10 degrees (≤10°), or less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). The angle here is not limited to integer angles, but can be any angle within a limited range, such as 0.09°, 1.3°, 2.5°, 3°, etc. In some embodiments, the two second cutting wheels arranged vertically above and below the second cutting saw form a second cutting wire saw, with the upper second cutting wheel in front in a first direction and the lower second cutting wheel in a first direction behind in a first direction. The resulting second cutting wire saw can form a positive deflection angle with the vertical. In some embodiments, the two second cutting wheels arranged vertically above and below the second cutting saw form a second cutting wire saw, with the upper second cutting wheel in a first direction behind in a first direction and the lower second cutting wheel in front in a first direction. The resulting second cutting wire saw can form a negative deflection angle with the vertical. The deflection angle (including positive and negative deflection angles) can be varied according to the cutting process requirements and the size specifications of the silicon rod. For example, the angle can be adjusted by changing the position of one or both of the two upper and lower second cutting wheels associated with the second cutting wire saw.

[0149] In some embodiments, the second wire cutting unit further includes a second tension adjustment mechanism. During wire cutting, the tension of the cutting wire affects the yield and processing accuracy. The second tension adjustment mechanism detects and adjusts the tension so that the tension of the second cutting wire reaches a set threshold and remains constant during cutting, or within a certain range allowed by the constant value. In some embodiments, the second tension adjustment mechanism is associated with a second transition wheel 153 or a second cutting wheel. The second transition wheel 153 in the wire cutting unit, while guiding and pulling the second cutting wire 154, also serves as a tensioning wheel for adjusting the cutting wire tension.

[0150] In some embodiments, the second silicon rod cutting device further includes: at least one second adjustment mechanism disposed in at least one second wire cutting unit, for driving a plurality of second cutting wheels in the second wire cutting unit to move in a direction perpendicular to the wheel surface. The second silicon rod cutting device can realize the switching of the second cutting line between different cutting grooves of the second cutting wheel based on the adjustment mechanism, or adjust the position of the second cutting wire saw to change the cutting position (or processing specifications) relative to the silicon rod.

[0151] In some implementations, a second wire cutting unit within a second silicon rod cutting apparatus is used as an example. This second wire cutting unit includes multiple second cutting wheels and multiple second transition wheels. The carrier supporting the multiple second cutting wheels and second transition wheels is, for example, a second cutting mounting structure. A second adjusting mechanism can be used to drive the entire second cutting mounting structure to move along the perpendicular direction of the cutting wheel surface. The second transition wheels and second cutting wheels move together along the perpendicular direction of the second cutting wheel surface (i.e., the transposition direction or the second direction Y-axis) following the second cutting mounting structure. In this state, the multiple second cutting wheels and second transition wheels are relatively stationary; that is, the positional relationship between the second transition wheels and the second cutting wheels remains unchanged. At this time, the second adjusting mechanism is used to adjust the cutting position of at least one second wire saw in at least one second wire cutting unit relative to the silicon rod.

[0152] In some implementations, each second cutting wheel has at least two second cutting grooves, which are parallel to each other and have a cutting offset perpendicular to the wheel surface. When the second adjusting mechanism drives the plurality of second cutting wheels in the second wire cutting unit to move relative to the second cutting mounting structure, the position of the grooves around the second cutting wires on the second cutting wheels can be changed. In some implementations, the plurality of second cutting wheels in the second wire cutting unit may, for example, be connected to a bracket, wherein the bracket is movably disposed on the second cutting mounting structure and driven by the second adjusting mechanism to move along the perpendicular direction of the wheel surface.

[0153] When at least one second adjusting mechanism is used to change the cutting groove of the second cutting line around multiple second cutting wheels in at least one second wire cutting unit, in a practical scenario, the second cutting grooves corresponding to the cutting lines before and after the groove change can be predetermined. For example, before the groove change, the position of the second cutting line is the second cutting groove a1, and after the groove change, the second cutting line is around the second cutting groove a2. The displacement amount that the second adjusting mechanism drives the multiple second cutting wheels in the second wire cutting unit to move is determined based on the cutting offset between the second cutting groove a1 and the second cutting groove a2. That is, the displacement amount is set as the second cutting line... The cutting offset between slot a1 and the second cutting line slot a2 can be used to change the second cutting line from the second cutting line slot a1 to the second cutting line slot a2. It should be noted that at least one second adjustment mechanism drives multiple second cutting wheels in the second wire cutting unit to move in the direction perpendicular to the surface of the second cutting wheel, with the direction from cutting line slot a2 to cutting line slot a1. After the slot is changed, the cutting position of the second cutting wire saw in space remains unchanged, thus eliminating the need for further calibration of the position of the second cutting wheel or other components. The silicon rod can be cut according to the preset cutting amount, which simplifies the slot changing process.

[0154] To further illustrate how at least one second adjustment mechanism enables the movement of multiple second cutting wheels in the second wire cutting unit along a direction perpendicular to the wheel surface, this application discloses the following embodiments. The specific form of the at least one second adjustment mechanism can vary depending on the number of second wire cutting units in the second silicon rod cutting apparatus.

[0155] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, which is a second wire cutting unit. The second pitch adjustment mechanism includes: a lead screw, which is arranged in an orthogonal direction to the surface of the second cutting wheel and threadedly connected to the single-wire cutting unit; and a lead screw drive source for driving the lead screw to rotate.

[0156] In some embodiments, such as Figure 13 As shown, the second silicon rod cutting device includes two second wire cutting units arranged in parallel and opposite directions. At least one of the two second wire cutting units can be driven to move in the orthogonal direction of the second cutting wheel surface by at least one pitch adjustment mechanism, which is used to adjust the wire cutting saw spacing between the second wire saws in the two second wire cutting units, or to change the cutting wire grooves of the second cutting wires wound around the multiple second cutting wheels in a certain second wire cutting unit.

[0157] At least one second adjustment mechanism can be configured to be connected to a certain second wire cutting unit, or simultaneously associated with two second wire cutting units, so as to drive multiple second cutting wheels in the connected or associated one or two second wire cutting units to move in the orthogonal direction of the wheel surface of the second cutting wheel.

[0158] As previously described, in the second silicon rod cutting device, the second wire saws of two parallel second wire cutting units are arranged vertically or at an angle to the vertical, driving the second silicon rod transfer device and the silicon rod it carries to move along the transfer direction. Through the relative movement of the second wire cutting units and the second silicon rod transfer device along the transfer direction, the second wire saws in the two second wire cutting units perform a second cutting operation on the silicon rod carried by the second silicon rod transfer device. Using the second wire cutting units to cut the silicon rod results in a cut surface and an edge. That is, cutting the silicon rod with one wire saw in one second wire cutting unit creates a cut surface and leaves an edge. Therefore, by using the second wire saws in the two parallel second wire cutting units in the second silicon rod cutting device to perform a second cutting operation on a silicon rod with a circular cross-section, the silicon rod can form two parallel second side cut surfaces.

[0159] In addition to the second wire cutting unit, the second silicon rod cutting device also includes at least one third wire cutting unit, wherein the at least one third wire cutting unit is formed with at least one third wire saw. The at least one third wire saw is located in the vertical plane and is arranged along the vertical or at an angle to the vertical. The at least one third wire saw is used to perform a second cutting operation on the silicon rod carried by the second silicon rod carrying device so that the silicon rod is obtained as at least two half rods with a rectangular cross-section after forming at least one cutting surface.

[0160] The third wire cutting unit includes multiple third cutting wheels and a third cutting wire. The third cutting wire is sequentially wound around the multiple third cutting wheels to form at least one third wire saw arranged vertically or at an angle to the vertical. The third wire cutting unit moves relative to the second silicon rod transfer device and the silicon rod it carries at the second cutting station, and at least one third wire saw performs a second cutting operation on the silicon rod carried by the second silicon rod transfer device. In some embodiments, the third cutting wire is wound in a loop between the third cutting wheels, where the first and last ends are connected. In this case, the third cutting wire can also be called a closed-loop cutting wire.

[0161] In some embodiments, such as Figure 13 As shown, the second silicon rod cutting device 15 includes a third wire cutting unit 156 located between two second wire cutting units 151. The third wire cutting unit includes a plurality of third cutting wheels and a third cutting wire. The third cutting wire is wound around the plurality of third cutting wheels to form at least one third wire saw. The third wire saw is arranged vertically or at an angle to the vertical.

[0162] like Figure 13 As shown, the second silicon rod cutting device 15 includes a third wire cutting unit 156 between two second wire cutting units 151. The third wire cutting unit 156 includes a plurality of third cutting wheels 157 and a third cutting wire 158. The third cutting wire 158 is wound around the plurality of third cutting wheels 157 to form at least one third wire saw 159, wherein the third wire saw 159 is arranged vertically or at an angle to the vertical. Figure 13As shown, the second silicon rod cutting device 15 may include two second wire cutting units 151 and one third wire cutting unit 156. Each second wire cutting unit 151 has a second wire cutting saw 155, and each third wire cutting unit 156 has a third wire cutting saw 159. Therefore, the second silicon rod cutting device 15 may include two second wire cutting saws 155 and one third wire cutting saw 159. Both the two second wire cutting saws 155 and the one third wire cutting saw 159 are arranged vertically or at an angle to the vertical. The third wire cutting saw 159 is located between the two second wire cutting saws 155 and is centrally positioned. The third wire cutting saw 159 performs a second cutting operation on the silicon rod, which can cut the silicon rod into two halves of the same size. However, this is not a limitation. In some embodiments, the third wire cutting saw 159 is located between the two second wire cutting saws 155 but is not centrally positioned. The third wire cutting saw 159 performs a second cutting operation on the silicon rod, which can cut the silicon rod into two halves of different sizes. In some embodiments, the second silicon rod cutting device includes a third wire cutting unit, which includes two or more third wire saws. These three wire saws are parallel to each other and arranged vertically or at an angle to the vertical. In some embodiments, the second silicon rod cutting device includes two or more third wire cutting units, where the two or more third wire saws in these units are parallel to each other and arranged vertically or at an angle to the vertical. The silicon rod is cut into three or more halves of the same or different sizes by two or more third wire saws performing a second cutting operation. In this application, for ease of description, the cut portion of the silicon rod is referred to as a half-rod. In reality, when the number of third wire saws is two or more, the cut portion of the silicon rod is likely to be less than half the total size of the silicon rod. Therefore, "half-rod" can also use other terms, such as "small rectangular rod," "sub-rod," "sub-rod," "small silicon rod," "small square rod," etc.

[0163] Furthermore, it should be noted that because the second silicon rod cutting device includes at least one third wire cutting unit, the second supporting platform in the second silicon rod transfer device is provided with at least one wire receiving groove corresponding to at least one third wire saw. In such a case... Figure 13In the illustrated embodiment, the second silicon rod cutting device 15 includes a third wire cutting unit 156 between two second wire cutting units 151. The third wire cutting unit 156 has a third wire saw 159. Therefore, the second support platform 141 in the second silicon rod transfer device 14 is provided with a wire receiving groove 142 corresponding to the third wire saw 159. The wire receiving groove 142 is arranged along the transfer direction (i.e., the first direction), and the width of the wire receiving groove 142 is greater than that of the third wire saw 159 to accommodate the third wire saw 159. In some embodiments, the width of the wire receiving groove is much greater than the wire diameter of the third wire saw (e.g., greater than or equal to 5 or 10 times the wire diameter of the third wire saw) to provide displacement of the third wire saw in the width direction of the wire receiving groove (i.e., the transposition direction or the second direction Y-axis). In some embodiments, the second silicon rod cutting device includes two or more third wire saws (in some embodiments, the second silicon rod cutting device includes a third wire cutting unit, and the wire cutting unit includes two or more third wire saws; or, in some embodiments, the second silicon rod cutting device includes two or more third wire cutting units, and each third wire cutting unit includes at least one third wire saw), then the second support platform is provided with two or at least two wire receiving grooves corresponding to the two or more third wire saws.

[0164] In such Figure 13 In the illustrated embodiment, each third cutting wheel 157 in the third wire cutting unit 156 is coaxially arranged with each second cutting wheel 152 in a adjacent second wire cutting unit 151. That is, the third cutting wheel 157 in the third wire cutting unit is coaxial with the corresponding second cutting wheel 152 in the adjacent second wire cutting unit 151 and is disposed on the second cutting mounting structure 150. However, this is not a limitation. In some embodiments, the third wire cutting unit 156 may include a third cutting mounting structure, and the aforementioned plurality of third cutting wheels 157 may be disposed on the third cutting mounting structure.

[0165] In the integrated cutting and grinding equipment for small-sized rectangular rods in this application, the third wire saw in the third wire cutting unit of the second silicon rod cutting device is arranged along the vertical direction or at an angle to the vertical direction.

[0166] In the third wire cutting unit, the third cutting wheel is provided with at least one third cutting groove for winding the cutting wire. The third cutting groove can define the position of the third cutting wire, thereby controlling the cutting accuracy. Any third wire saw is formed between two opposing third cutting wheels after the third cutting wire is wound around it. The positions of the two third cutting wheels and the positional relationship between the third cutting wheels can be used to determine the direction of the third wire saw.

[0167] like Figure 13As shown, in some embodiments, the third cutting unit includes multiple third cutting wheels 157, such as four third cutting wheels 157, arranged in a rectangular shape, with the wheel surface of each third cutting wheel 157 located in a vertical plane (the vertical plane is formed by a first direction and a third direction). Two third cutting wheels 157 are positioned in front (relatively closer to the second loading / unloading area) and arranged vertically in parallel, while the other two third cutting wheels 157 are positioned behind (relatively farther from the second loading area) and arranged vertically in parallel. A third cutting line 158 is wound around these four third cutting wheels 157 to form at least one third cutting wire saw 159 (for example, a third cutting wire saw 159 is formed between the two front and vertically parallel third cutting wheels 157). The third cutting wire saw 159 is arranged along a third direction (i.e., vertical). Furthermore, to enable the third cutting wire saw 159 to effectively cut the silicon rod, the third cutting wire saw 159 must interfere with the silicon rod in the vertical direction.

[0168] In some embodiments, the third cutting line is wound around each of the third cutting wheels in an end-to-end manner to form a loop cutting line (also known as a closed-loop cutting line). Figure 13 In the embodiment shown, the third cutting line 158 is wound around the plurality of third cutting wheels 157 in a continuous manner to form a ring cutting line (also known as a closed-loop cutting line).

[0169] In the third cutting unit, multiple third cutting wheels are wound around a circular cutting wire. In this example, the second silicon rod cutting device can eliminate the need for a wire storage spool. The circular cutting wire, driven by a cutting wire drive device, can maintain high-speed operation. Furthermore, the circular cutting wire can run in the same direction during the cutting operation. Thus, the second silicon rod cutting device can achieve high-precision second cutting operations, avoiding problems such as wavy cut surfaces caused by wire reversal or speed changes in existing cutting methods. Simultaneously, the circular cutting wire effectively reduces the total length of the cutting wire required for the third wire cutting unit, lowering production costs.

[0170] In some embodiments, the cutting wire drive device is a motor with a power output shaft connected to the third cutting wheel. Thus, the third cutting wire can be driven by the wound third cutting wheel to run along the winding direction. Of course, in specific implementations, the cutting wire drive device can also be other drive sources such as a hydraulic motor, as long as it drives the third cutting wire; this application does not impose any limitations. As mentioned above, in some embodiments, each third cutting wheel in the third wire cutting unit is coaxially arranged with each second cutting wheel in an adjacent second wire cutting unit. Therefore, each third cutting wheel in the third wire cutting unit can be driven by the cutting wire drive device in the second wire cutting unit, eliminating the need to configure a corresponding cutting wire drive device for the third wire cutting unit.

[0171] The third wire cutting unit in this application may further include a third transition wheel, which is used to reverse or guide the third cutting line, or, alternatively, to adjust the tension of the third cutting line. The number of third transition wheels may be one or more depending on the layout requirements.

[0172] The third transition wheel guides and pulls the third cutting wire while simultaneously acting as a tensioning wheel to adjust the tension of the third cutting wire. The tensioning wheel is used to adjust the tension of the third cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0173] like Figure 13 As shown, for example, in some embodiments, the third wire cutting unit 156 includes a plurality of third cutting wheels 157 and a plurality of third transition wheels 157', for example, two third cutting wheels 157 and two third transition wheels 157', and the wheel surfaces of the two third cutting wheels 157 and the two third transition wheels 157' are all located in the vertical plane. The two third cutting wheels 157 are arranged in front and parallel vertically, and the two third transition wheels 157' are arranged in the back and parallel vertically. The third cutting line 158 is wound around the two third cutting wheels 157 and the two third transition wheels 157' to form at least one third cutting wire saw 159 (for example, a third cutting wire saw 159 is formed between the two third cutting wheels 157). The at least one third cutting wire saw 159 is arranged vertically.

[0174] As before, the third cutting line 158 is wound around multiple third cutting wheels 157 or multiple third cutting wheels 157 and multiple third transition wheels 157' to form a third cutting line saw 159 between the two preceding third cutting wheels 157. Therefore, to adjust the line length of the third cutting line saw 159, the spacing between the two third cutting wheels 157 can be adjusted, which can be achieved by changing the position of at least one of the two third cutting wheels 157.

[0175] The third wire saw is arranged vertically or at an angle to the vertical, while the silicon rod carried by the second silicon rod transfer device at the corresponding second cutting station is placed horizontally (the axis of the silicon rod is arranged along the transfer direction). Therefore, in order to cut the silicon rod, the length of the third wire saw is adapted to the size of the end face of the silicon rod. For example, the length of the third wire saw must be greater than or equal to the diameter of the silicon rod or the chord length at the position where the silicon rod is to be cut.

[0176] The direction of the third cutting wheel surface corresponds to the direction of the third cutting wire saw. It should be understood that the third cutting wheel surface is parallel to the plane where any of the third cutting wire grooves in the third cutting wheel are located. In order to control the cutting accuracy and the stability of the cutting process, the third cutting wire saw should be located in the plane where the third cutting wire groove is used to wind the third cutting wire. At the same time, during the cutting process, the direction of the force applied by the silicon rod to the third cutting wire should be parallel to the cutting wire groove, that is, the cutting wheel surface should be parallel to the cutting direction. The cutting direction in the second cutting operation is the direction of the silicon rod axis, that is, the transfer direction (i.e., the first direction X-axis).

[0177] The second silicon rod cutting device includes a third wire cutting unit located between and parallel to the two second wire cutting units. The third wire cutting unit has a third wire saw, which is arranged vertically or at an angle to the vertical.

[0178] In fact, the third wire saw can still have other variations. In some embodiments, the third wire saw is arranged vertically, but this is not a limitation. In other embodiments, the position of the third wire saw can be located in the vertical plane and arranged at an angle to the vertical (i.e., the third direction). The vertical plane is composed of the third direction and the third direction, and the angle is less than or equal to 10 degrees (≤10°), or less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). That is, the wire cutting direction of the third wire saw can be located in the vertical plane with the third direction (i.e., the vertical) and form an angle of less than or equal to 10 degrees (≤10°), or less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). The angle here is not limited to integer angles, but can be any angle within a limited range, such as 0.09°, 1.3°, 2.5°, 3°, etc. In some embodiments, the two third cutting wheels arranged vertically above and below the third cutting saw form a third cutting wire saw, with the upper third cutting wheel in front in a first direction and the lower third cutting wheel in a first direction behind in a first direction. The resulting third cutting wire saw can form a positive deflection angle with the vertical. In other embodiments, the two third cutting wheels arranged vertically above and below the third cutting saw form a third cutting wire saw, with the upper third cutting wheel in a first direction behind in a first direction and the lower third cutting wheel in front in a first direction. The resulting third cutting wire saw can form a negative deflection angle with the vertical. The deflection angle (including positive and negative deflection angles) can be varied according to the cutting process requirements and the size specifications of the silicon rod. For example, the angle can be adjusted by changing the position of one or both of the two vertically arranged third cutting wheels associated with the third cutting wire saw.

[0179] In some embodiments, the third wire cutting unit further includes a third tension adjustment mechanism. During wire cutting, the tension of the cutting wire affects the yield and processing accuracy. The third tension adjustment mechanism detects and adjusts the tension so that the tension of the third cutting wire reaches a set threshold and remains at a constant value or within a certain range allowed by the constant value during cutting.

[0180] In some embodiments, the third tension adjustment mechanism is associated with a third transition wheel or a third cutting wheel. The third transition wheel in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while guiding the third cutting wire 158.

[0181] In some embodiments, the second silicon rod cutting apparatus further includes: at least one third adjustment mechanism, disposed in at least one third wire cutting unit, for driving a plurality of third cutting wheels in the third wire cutting unit to move in a direction perpendicular to the wheel surface. The second silicon rod cutting apparatus can switch the third cutting line between different cutting slots of the third cutting wheel based on the adjustment mechanism, or adjust the position of the third cutting wire saw to change the cutting position (or processing specifications) relative to the silicon rod.

[0182] In some implementations, a third wire cutting unit within a second silicon rod cutting apparatus is used as an example. This third wire cutting unit includes multiple third cutting wheels and multiple third transition wheels. A third adjustment mechanism can be used to drive the multiple third cutting wheels and multiple third transition wheels to move along the perpendicular direction of the cutting wheel surface (i.e., the transposition direction or the second direction Y-axis). In this state, the third cutting wheels and third transition wheels are relatively stationary; that is, the positional relationship between the third transition wheels and the third cutting wheels remains unchanged. At this time, the third adjustment mechanism is used to adjust the cutting position of at least one third wire saw in the third wire cutting unit relative to the silicon rod.

[0183] Each third cutting wheel has at least two third cutting grooves, which are parallel to each other and have a cutting offset perpendicular to the wheel surface. When the third adjusting mechanism is used to drive the multiple third cutting wheels in the third wire cutting unit to move, the position of the grooves around the third cutting wire on the third cutting wheel can be changed.

[0184] When at least one third adjustment mechanism is used to change the cutting groove of the third cutting line around multiple third cutting wheels in at least one third wire cutting unit, in a practical scenario, the third cutting grooves corresponding to the cutting lines before and after the groove change can be predetermined. For example, before the groove change, the position of the third cutting line is the third cutting groove a1, and after the groove change, the third cutting line is wrapped around the third cutting groove a2. The displacement amount that the third adjustment mechanism drives the multiple third cutting wheels in the third wire cutting unit to move is determined based on the cutting offset between the third cutting groove a1 and the third cutting groove a2. That is, the displacement amount is set as the third cutting line. The cutting offset between slot a1 and the third cutting slot a2 can be used to change the third cutting line from the third cutting slot a1 to the third cutting slot a2. It should be noted that at least one third adjustment mechanism drives multiple third cutting wheels in the third wire cutting unit to move in the direction perpendicular to the surface of the third cutting wheel, with the direction from cutting slot a2 to cutting slot a1. After the slot change, the cutting position of the third cutting wire saw in space remains unchanged, thus eliminating the need for further calibration of the position of the third cutting wheel or other components. The silicon rod can be cut according to the preset cutting amount, which simplifies the slot change process.

[0185] To further illustrate how at least one third adjustment mechanism enables the movement of multiple third cutting wheels in the third wire cutting unit along a direction perpendicular to the wheel surface, this application discloses the following embodiments. The specific form of the at least one third adjustment mechanism can vary depending on the number of third wire cutting units in the second silicon rod cutting apparatus.

[0186] As before, in the second silicon rod cutting device, a third wire cutting unit is configured between the two second wire cutting units. The third wire saw in the third wire cutting unit is arranged vertically or at an angle to the vertical, driving the second silicon rod transfer device and the silicon rod it carries to move along the transfer direction. By moving the third wire cutting unit relative to the second silicon rod transfer device along the transfer direction, the third wire saw in the third wire cutting unit performs a second cutting operation on the silicon rod carried by the second silicon rod transfer device, so that the silicon rod can be divided into two halves after forming a slit surface. In the second silicon rod cutting device, two or more third wire cutting units are arranged between two second wire cutting units. The third wire saw in each third wire cutting unit is arranged vertically or at an angle to the vertical. In this way, the second silicon rod transfer device and the silicon rod it carries are driven to move along the transfer direction. By having two or more third wire cutting units move relative to the second silicon rod transfer device along the transfer direction, the third wire saw in the two or more third wire cutting units performs a second cutting operation on the silicon rod carried by the second silicon rod transfer device. This allows the silicon rod to form two or more slit surfaces and obtain three or more half rods with rectangular cross sections.

[0187] The half-rod cutting equipment includes a second edge-skin anti-splitting device that works in conjunction with the second silicon rod transfer device to stabilize the edge skin when the second silicon rod cutting device performs the second cutting operation on the silicon rod.

[0188] It should be understood that the silicon rod carried by the second silicon rod transfer device is horizontal, meaning that the axis of the silicon rod is aligned with the transfer direction (i.e., the first direction X-axis). Therefore, the edge formed by the second silicon rod cutting device performing the second cutting operation on the silicon rod is also horizontal.

[0189] In some embodiments, the second edge-skin anti-splitting device includes a clamping support and an edge-skin clamp, wherein the edge-skin clamp is disposed on the clamping support and is used to clamp the edge-skin.

[0190] When performing a second cutting operation on a silicon rod using the second silicon rod cutting device in the small-size rectangular rod cutting and grinding integrated equipment of this application, the silicon rod with two first side cut surfaces is placed horizontally on the second silicon rod transfer device located in the second loading and unloading area (the first side cut surfaces of the silicon rod are in contact with the second silicon rod transfer device); the second silicon rod carrying device and the silicon rod it carries are driven to transfer from the second loading and unloading area to the second cutting area along the transfer direction; the edge clamp advance and retraction mechanism drives the edge clamp to advance along the advance and retraction direction to the silicon rod, and the second edge clamp anti-breakage mechanism is activated. The edge clamp of the edge device holds the silicon rod. At this time, the two parallel second wire saws and the central third wire saw in the second silicon rod cutting device are positioned between the edge clamp and the silicon rod. The second silicon rod transfer device is driven to carry the silicon rod forward along the transfer direction toward the second cutting area. The relative movement between the second silicon rod cutting device and the second silicon rod transfer device along the transfer direction allows the two parallel second wire saws and the central third wire saw in the second silicon rod cutting device to perform a second cut on the circular silicon rod. The process involves using two second-cutting wire saws to remove two edge strips from the silicon rod, creating two parallel second-side cut surfaces perpendicular to the first side cut surface. A third-cutting wire saw is then used to cut the silicon rod again, creating a slit surface that yields two halves of the rod, with the slit surface parallel to the second side cut surfaces. The edge strip anti-chipping device utilizes an edge strip clamping mechanism; this mechanism drives the edge strip clamp to retract in the forward / backward direction, thus detaching the clamped edge strip from the silicon rod body. The process involves: 1) Lowering the edge clamp and its gripped edge via a clamp lifting mechanism to release the edge clamp and place the edge onto the edge support structure; 2) Transferring the edge support structure from the second cutting area to the second loading / unloading area via a conveying drive mechanism; 3) Flipping the edge support structure and its gripped edge via an edge flipping mechanism to unload the flipped edge; 4) Transferring the second silicon rod support device and its gripped silicon rod body from the second cutting area to the second loading / unloading area along the transfer direction to complete the second cutting operation of the silicon rod.

[0191] The integrated cutting and grinding equipment for small rectangular rods in this application also includes a silicon rod loading and unloading device, which is used to load a silicon rod with a circular cross-section onto a first silicon rod transfer device, unload the silicon rod that has completed the first cut from the first silicon rod transfer device and load it onto a second silicon rod transfer device, and unload the half rod that has completed the second cut from the second silicon rod transfer device and load it onto a half rod grinding device.

[0192] In some embodiments, the silicon rod loading and unloading device includes: a silicon rod mounting frame, a silicon rod clamp, and a clamp repositioning mechanism, wherein the silicon rod mounting frame is mounted across the cutting machine base along the repositioning direction, the silicon rod clamp is used to clamp the two end faces of the silicon rod, and the clamp repositioning mechanism is used to drive the silicon rod clamp to move along the repositioning direction to move the silicon rod clamp on the silicon rod mounting frame.

[0193] In such Figure 1 and Figure 2 In the embodiment shown, the half-rod cutting equipment includes a silicon rod loading and unloading device 17, which includes a silicon rod mounting frame 171, a silicon rod clamp 172, and a clamp repositioning mechanism.

[0194] The silicon rod mounting bracket spans across the cutting machine base along the transposition direction. In some embodiments, the silicon rod mounting bracket spans across the cutting machine base along the transposition direction, which is consistent with the second direction. The length of the silicon rod mounting bracket should be sufficient to cover the entire cutting processing platform of the cutting machine base. When multiple cutting stations along the second direction are provided on the cutting processing platform, the length of the silicon rod mounting bracket should be long enough to cover the multiple cutting stations.

[0195] Silicon rod clamps are used to hold the two end faces of a silicon rod. In some embodiments, the silicon rod clamp includes a clamp mounting bracket and a silicon rod holding element. See also... Figure 2 The image shows a schematic diagram of a silicon rod clamp in one embodiment. Figure 1 and Figure 2 In the embodiment shown, the silicon rod clamp 172 includes a clamp mounting frame 173 and a silicon rod holder 174.

[0196] The fixture mounting frame is installed on the silicon rod mounting frame. The fixture mounting frame is used to set up silicon rod clamping components. Here, the specific structure of the fixture mounting frame can be set in different forms according to the arrangement requirements of the silicon rod clamping components, such as beams, frames, plate frames, etc.

[0197] The silicon rod holder is mounted on a fixture mounting frame. In some embodiments, the silicon rod holder moves up and down relative to the fixture mounting frame via a fixture lifting mechanism.

[0198] A silicon rod clamp is used to clamp silicon rods. In some embodiments, the silicon rod clamp includes: a clamp arm mounting base, at least one pair of clamp arms, and a clamp arm drive mechanism; the clamp arm mounting base is disposed on a fixture mounting frame.

[0199] As previously mentioned, in some embodiments, the silicon rod holder moves up and down relative to the fixture mounting frame via a fixture lifting mechanism.

[0200] In some embodiments, the clamp lifting mechanism includes a lifting guide rod and a lifting drive unit. The lifting guide rod is arranged along the lifting direction and is used to set the silicon rod clamping member. Specifically, the lifting guide rod is associated with a clamping arm mounting base. The lifting drive unit is used to drive the silicon rod clamping member to move up and down along the lifting guide rod. In some implementations, the lifting drive unit includes a drive motor and a lead screw assembly arranged along the lifting direction and driven by the drive motor. The drive motor may be located at one end of the lead screw assembly and mounted on the clamp mounting frame. The lead screw assembly is controlled by the drive motor and screwed to the clamping arm mounting base of the silicon rod clamping member. Thus, when the clamp lifting mechanism is used, the drive motor drives the lead screw assembly to rotate forward, thereby causing the silicon rod clamping member connected to the lead screw assembly to move upward along the lifting guide rod; or, the drive motor drives the lead screw assembly to rotate in the reverse direction, thereby causing the silicon rod clamping member connected to the lead screw assembly to move downward along the lifting guide rod.

[0201] At least one pair of clamping arms are disposed opposite each other on the clamping arm mounting base along the transfer direction, for clamping the two end faces of the silicon rod. Each of the at least one pair of clamping arms has a clamping portion for directly contacting and clamping the silicon rod. In some embodiments, the clamping arm extends downward from the clamping arm mounting base; that is, the bottom of the clamping arm is disposed on the clamping arm base, and the top of the clamping arm has a clamping portion for contacting and clamping the end faces of the silicon rod. In this application, for the silicon rod to be cut, the silicon rod to be cut is a cylindrical structure with a certain length, and its length direction is placed along the transfer direction (i.e., the first direction), with the end faces being the faces at both ends of the length direction. For the cut half-rod, the half-rod is a cuboid structure with a certain length (its cross-section is rectangular or quasi-rectangular), and its length direction is placed along the transfer direction (i.e., the first direction), with the end faces being the faces at both ends of the length direction.

[0202] The silicon rod clamp also includes a clamping arm drive mechanism, which drives at least one of the at least one pair of clamping arms to move along the transfer direction to adjust the clamping distance between the pair of opposing clamping arms. Thus, the clamping portions of at least one pair of clamping arms can move closer or further apart under the action of the clamping arm drive mechanism to perform clamping or releasing actions on the silicon rod.

[0203] In some embodiments, the clamping arm driving mechanism includes a moving guide rail and a clamping arm driving unit. The moving guide rail is arranged along a transfer direction (i.e., a first direction) and is used to mount at least one pair of clamping arms. In some implementations, at least one of the clamping arms has a guide groove structure at its bottom that matches the moving guide rail. The clamping arm driving unit is associated with at least one of the clamping arms and is used to drive the associated clamping arm to move along the moving guide rail.

[0204] In some embodiments, the clamping arm drive unit includes: a movable rack and pinion, disposed on the clamping arm mounting base along the transfer direction; a drive gear, disposed on the associated clamping arm and meshing with the movable rack and pinion; and a gear drive source for driving the drive gear to rotate, thereby moving the associated clamping arm along the transfer direction. The movable rack and pinion may be a rack and pinion structure, and the gear drive source may be, for example, a servo motor. In the above embodiments, the movable rack and pinion, drive gear, and gear drive source in the clamping arm drive unit may be implemented in different ways.

[0205] In some implementations, when driving a clamping arm, a clamping arm drive unit can be provided. This unit includes a moving toothed track, a drive gear, and a gear drive source. In practical applications, the gear drive source drives the drive gear to rotate, causing the associated clamping arm to move along the moving toothed track, for example, moving closer to another clamping arm (reducing the clamping distance between the two clamping arms) or moving away from another clamping arm (increasing the clamping distance between the two clamping arms).

[0206] In some implementations, when driving a pair of grippers, two gripper drive units can be provided. Each gripper drive unit includes a moving toothed track, a drive gear, and a gear drive source. In practical applications, for each gripper, the drive gear is driven to rotate by the gear drive source, causing the associated gripper to move along the moving toothed track. Thus, by using two gripper drive units to drive their respective grippers, the two grippers can be driven to move towards each other (the two grippers move closer together to reduce the clamping distance) or away from each other (the two grippers move away from each other to increase the clamping distance).

[0207] In some embodiments, the clamping arm drive unit includes: a movable rack and pinion, disposed on the associated clamping arm along the transfer direction; a drive gear, disposed on the clamping arm mounting base and meshing with the movable rack and pinion; and a gear drive source for driving the drive gear to rotate, thereby moving the associated clamping arm along the transfer direction. The movable rack and pinion may be a rack and pinion structure, and the gear drive source may be, for example, a servo motor. In the above embodiments, the movable rack and pinion, drive gear, and gear drive source in the clamping arm drive unit may be implemented in different ways.

[0208] In some implementations, when driving a clamping arm, a clamping arm drive unit can be provided. This unit includes a moving toothed track, a drive gear, and a gear drive source. In practical applications, the gear drive source drives the drive gear to rotate, causing the associated clamping arm to move along the moving toothed track, for example, moving closer to another clamping arm (reducing the clamping distance between the two clamping arms) or moving away from another clamping arm (increasing the clamping distance between the two clamping arms).

[0209] In some implementations, when driving a pair of grippers, two gripper drive units can be provided. Each gripper drive unit includes a moving toothed track, a drive gear, and a gear drive source. In practical applications, for each gripper, the drive gear is driven to rotate by the gear drive source, causing the associated gripper to move along the moving toothed track. Thus, by using two gripper drive units to drive their respective grippers, the two grippers can be driven to move towards each other (the two grippers move closer together to reduce the clamping distance) or away from each other (the two grippers move away from each other to increase the clamping distance).

[0210] In some implementations, when driving a pair of clamping arms, a clamping arm drive unit can be provided. This unit includes two moving toothed rails, a drive gear, and a gear drive source. Each moving toothed rail is associated with a corresponding clamping arm, and the drive gear is mounted on the clamping arm mounting base and positioned between the two moving toothed rails, meshing with both rails simultaneously. In practical applications, a servo motor drives the drive gear to rotate, causing the associated, opposing clamping arm mounting bases and their clamping arms to move towards each other (the two clamping arms move closer together to reduce the clamping distance) or away from each other (the two clamping arms move further apart to increase the clamping distance).

[0211] The clamping arm drive unit includes: a movable lead screw, arranged along the transfer direction and associated with a corresponding clamping arm; and a lead screw drive source for driving the movable lead screw to rotate, thereby moving the associated clamping arm along the transfer direction. The lead screw drive source can be, for example, a servo motor. In embodiments, the movable lead screw and the lead screw drive source in the clamping arm drive unit can be implemented in different ways.

[0212] In some implementations, when driving a clamping arm, a clamping arm driving unit can be provided. This unit includes a movable lead screw and a lead screw drive source, wherein the movable lead screw is positioned along the transfer direction and associated with the corresponding clamping arm. In practical applications, the lead screw drive source drives the movable lead screw to rotate, causing the associated clamping arm to move along the transfer direction, for example, moving it closer to another clamping arm (reducing the clamping distance between the two clamping arms) or moving it away from another clamping arm (increasing the clamping distance between the two clamping arms).

[0213] In some implementations, when driving a pair of clamping arms, two clamping arm driving units can be provided. Each clamping arm driving unit includes a movable lead screw and a lead screw drive source, wherein each movable lead screw is associated with a corresponding clamping arm. In practical applications, for each clamping arm, the movable lead screw is driven to rotate by the lead screw drive source to move the associated clamping arm along the transfer direction. In this way, by using two clamping arm driving units to drive their respective corresponding clamping arms to move, the two clamping arms can be driven to move towards each other (the two clamping arms move closer to each other to reduce the clamping distance between the two clamping arms) or away from each other (the two clamping arms move away from each other to increase the clamping distance between the two clamping arms) along the moving toothed track.

[0214] To drive a pair of clamping arms, a clamping arm drive unit can be provided. This unit includes a movable lead screw and a lead screw drive source. The movable lead screw can be, for example, a bidirectional lead screw with threads at both ends in opposite directions. Each end of the bidirectional lead screw is associated with a pair of opposing clamping arms. In practical applications, the lead screw drive source drives the bidirectional lead screw to rotate, causing the two opposing clamping arms to move towards each other (the two clamping arms move closer together to reduce the clamping distance) or away from each other (the two clamping arms move further apart to increase the clamping distance) along a movable toothed track.

[0215] Of course, the clamping arm drive unit can still be modified in other ways. For example, in some embodiments, the clamping arm drive unit may include a telescopic cylinder, with each end of the telescopic cylinder associated with a pair of clamping arms disposed opposite to each other. Alternatively, in some embodiments, the clamping arm drive unit may include a clamping arm telescopic assembly, which includes a clamping arm telescopic rod and a clamping arm telescopic cylinder, with the clamping arm telescopic rod associated with a corresponding clamping arm and the clamping head telescopic cylinder associated with the clamping head telescopic rod.

[0216] Furthermore, in some embodiments, the clamping arms have a rotating structure. For example, the silicon rod clamp also includes a clamping arm rotation mechanism for driving the clamping arms to rotate. In some implementations, the clamping arm rotation mechanism is provided on at least one of the at least one pair of clamping arms, and any one of the clamping portions of the at least one pair of clamping arms or both clamping portions of a pair of clamping arms are provided with a rotatable structure. Under the drive of the clamping arm rotation mechanism, the clamping portion of the clamping arm rotates about the axis of the silicon rod, and the clamped silicon rod rotates accordingly about the axis of the silicon rod. For example, in some examples, the clamping arm rotation mechanism may be a rotary motor, and the clamping parts of both clamping arms in a pair of clamping arms are provided with rotatable structures. The clamping parts of the two clamping arms or one of the clamping arms are connected to the output shaft of the rotary motor. For example, the clamping parts of the two clamping arms are respectively connected to a rotary motor, and the two rotary motors drive the clamping parts of the corresponding clamping arms to rotate. Alternatively, the clamping part of one clamping arm is connected to a rotary motor, and the rotary motor drives the clamping part of that corresponding clamping arm to rotate. By using friction, through the conduction of the clamped silicon rod, the clamping part of the other clamping arm is also driven to rotate accordingly.

[0217] In some embodiments, at least one pair of clamping arms has a clamping portion with a contact surface for clamping a silicon rod or half-rod. The contact surface is disposed on a rotatable platform, the cross-section of which can be configured as a custom regular geometry or an irregular geometry.

[0218] In some embodiments, the rotatable platform may be configured as a single unit hinged together by a locking hinge mechanism, capable of rotating along an axis in the direction of transfer. The axis of rotation is connected to a clamping arm rotating mechanism.

[0219] In some embodiments, the clamping portion of the clamping arm can be configured as a rotatable frustum, the circular plane of which contacts the end face of the silicon rod, and remains relatively stationary after being pressed against the end face of the silicon rod. The clamping portion also includes a locking structure, which keeps the clamping portion in a locked state when performing corresponding processing operations on the silicon rod (such as cutting). During the switching of the silicon rod, such as the switching of the cutting position, the clamping portion rotates around the center of the frustum under the drive of the clamping arm rotation mechanism.

[0220] In some embodiments, the clamping portion of the clamping arm includes a rotatable frustum and a series of protruding contacts disposed on the frustum, each contact having a contact plane. The frustum rotates under the drive of the clamping arm rotation mechanism. In one implementation of this embodiment, the protrusion length of the contacts, i.e., their position in the transfer direction, is adjustable. This allows the protrusion length of the contacts to be adjusted according to the end face of the silicon rod during clamping, especially for silicon rods with low end face flatness, ensuring that each contact surface is in close contact with the end face of the silicon rod. The protrusion length is the length in the transfer direction from the circular plane of the frustum to the contact plane of the contact.

[0221] In some embodiments, the clamping portion of the silicon rod clamp is equipped with a pressure sensor to adjust the protrusion length of the contact points based on the detected pressure state. Typically, during the clamping of the silicon rod, a pair of clamping arms of the silicon rod clamp approach each other along the transfer direction under the drive of the clamping arm drive mechanism until the contact surface of the clamping portion contacts the end face of the silicon rod to be clamped. When the clamping portion is provided with multiple contacts and the pressure value detected when some contacts are in contact with the end face of the silicon rod is less than a set value or a set area, the clamping tightness can be changed by adjusting the protrusion length of the contact points (generally in the direction of approaching the end face of the silicon rod). Alternatively, each clamping portion of a pair of clamping arms of the silicon rod clamp is provided as a contact surface. During the clamping of the silicon rod, the clamping arm drive mechanism drives the pair of clamping arms to approach each other facing the end faces of the silicon rod. After the clamping portion contacts the end face of the silicon rod, the pressure sensor detects the degree of clamping of the silicon rod. When the set pressure range is reached, the clamping arm drive mechanism controls the pair of clamping arms to stop moving towards each other.

[0222] The clamping arm rotation mechanism can be installed on one of the clamping arms in a pair of clamping arms (the other clamping arm only has a rotation function) to drive the clamping parts of the pair of clamping arms to rotate with the silicon rod or half rod being clamped; or the clamping arm rotation mechanism can be installed on each clamping arm of a pair of clamping arms and coordinately control the two clamping parts of the pair of clamping arms to rotate at the same angle and in the same direction. In some implementations, the clamping arm rotation mechanism may include a drive motor.

[0223] When a silicon rod is cut by a silicon rod cutting device, the clamping part can be rotated by a clamping arm rotation mechanism. Typically, when cutting a single crystal silicon rod, the clamping arm rotation mechanism controls the clamping part to rotate by a certain angle, such as 90°, so that the silicon rod cutting device can cut one side or two opposite sides of the silicon rod.

[0224] In the integrated cutting and grinding equipment for small-sized rectangular rods of this application, the silicon rod loading and unloading device further includes a centering adjustment mechanism for adjusting the position of the silicon rod so that the axis of the silicon rod corresponds to a predetermined center line. In such cases... Figure 2 (or Figure 4In the embodiment shown, the centering adjustment mechanism 175 includes at least two clamping assemblies spaced apart along the transfer direction. Each clamping assembly includes two clamping members disposed opposite each other on the clamping arm mounting base along the clamping direction and a telescopic drive unit associated with the two clamping members. The telescopic drive unit is used to telescopically move the two clamping members relative to the clamping arm mounting base in the clamping direction. The clamping direction is perpendicular to the transfer direction and forms a horizontal plane, i.e., the clamping direction is a second direction. The clamping members may be, for example, clamping plates or clamping bars, and the telescopic drive unit may be, for example, a telescopic cylinder or a servo motor with a lead screw. In practical applications, when a silicon rod needs to be centered before being horizontally placed on the first silicon rod transfer device for the first cutting operation or before being placed on the second silicon rod transfer device for the second cutting operation, the at least two clamping assemblies in the centering adjustment mechanism can be operated. That is, the telescopic drive unit in the clamping assembly drives the two clamping members to retract relative to the clamping arm mounting base in the clamping direction, clamping the silicon rod between them to complete the centering operation. The operation is simple and fast.

[0225] A fixture shifting mechanism is used to drive the silicon rod fixture to move along the shifting direction. In some embodiments, the fixture shifting mechanism includes a fixture shifting guide rail and a fixture shifting drive unit. The fixture shifting guide rail is arranged on the silicon rod mounting bracket along the shifting direction, and the fixture shifting drive unit is associated with the silicon rod fixture and is used to drive the associated silicon rod fixture to move along the fixture shifting guide rail. The shifting direction is perpendicular to the transfer direction and forms a horizontal plane. Figure 1 The second direction, the Y-axis.

[0226] In some embodiments, the fixture shifting drive unit includes: a shifting gear, a drive gear, and a gear drive source. The shifting gear is arranged along the shifting direction, the drive gear is disposed on the silicon rod fixture and meshes with the shifting gear, and the gear drive source is used to drive the drive gear to rotate so that the associated silicon rod fixture moves along the shifting direction.

[0227] In such Figure 1 and Figure 2 (or Figure 4In the embodiment shown, the fixture shifting drive unit includes: a shifting gear, a drive gear, and a gear drive source. The shifting gear is arranged along the shifting direction, and its length in the shifting direction covers at least all the corresponding cutting stations and silicon rod cutting devices in the half-bar cutting equipment to ensure that the silicon rod fixture can be transferred to cover each cutting station. The shifting gear can adopt a rack structure. The drive gear is mounted on the fixture mounting frame of the silicon rod fixture and meshes with the shifting gear. The gear drive source is mounted on the fixture mounting frame of the silicon rod fixture and is associated with the drive gear. In practical applications, the gear drive source can be used to drive the drive gear to rotate, thereby moving the silicon rod fixture along the shifting direction via the shifting gear. For example, the gear drive source drives the drive gear to rotate forward, and through the engagement of the drive gear and the shifting gear, the associated silicon rod fixture moves forward along the shifting direction; the gear drive source drives the drive gear to rotate in the reverse direction, and through the engagement of the drive gear and the shifting gear, the associated silicon rod fixture moves backward along the shifting direction.

[0228] Of course, the structure of the fixture shifting drive unit can still be varied. For example, in some embodiments, the fixture shifting drive unit may include: a shifting screw, arranged along the shifting direction and associated with the fixture mounting frame of the silicon rod fixture; and a screw drive source for driving the shifting screw to rotate so that the associated silicon rod fixture moves along the shifting direction. In some embodiments, the chain conveying mechanism includes a ring chain and a chain drive source. The ring chain is associated with the fixture mounting frame of the silicon rod fixture. The ring chain may be, for example, a closed-loop chain, which is wound around a plurality of movable gears to form a preset shape. The chain drive source may be, for example, a servo motor.

[0229] In this application, the half-bar cutting equipment includes an edge unloading device for unloading the cut edge.

[0230] In some embodiments, the edge skin unloading device includes: an edge skin mounting frame, an edge skin adsorption component, and an adsorption component repositioning mechanism, wherein the edge skin mounting frame is mounted across the cutting machine base along the repositioning direction, the edge skin adsorption component is used to adsorb the edge skin, and the adsorption component repositioning mechanism is used to drive the adsorption component to move on the edge skin mounting frame along the repositioning direction.

[0231] In such Figure 1 and Figure 3 or Figure 4 In the illustrated embodiment, the half-bar cutting device 1 includes an edge unloading device 18, which can be located in the loading and unloading area of ​​the cutting processing platform to unload the cut edge from the cutting station (first cutting station or second cutting station) of the cutting processing platform. The loading and unloading area is located on the side of the cutting processing platform.

[0232] The edge unloading device 18 includes: an edge mounting bracket 181, an edge adsorption component 182, and an adsorption component repositioning mechanism.

[0233] The edge mounting bracket spans across the cutting machine base along the transposition direction. In some embodiments, the edge mounting bracket spans across the cutting machine base along the transposition direction, which is consistent with the second direction. The length of the edge mounting bracket is sufficient to cover the entire cutting platform of the cutting machine base. When the cutting platform has one or more cutting station groups, each cutting station group includes a first cutting station and a second cutting station along the second direction, the length of the edge mounting bracket is sufficient to cover each cutting station.

[0234] Edge skin adsorption components are used to adsorb edge skin. In some embodiments, the edge skin unloading device includes an adsorption component mounting structure, on which multiple edge skin adsorption components are provided along the transfer direction (i.e., the length direction of the edge skin). The edge skin adsorption component includes a suction cup. The edge skin adsorption component moves up and down relative to the edge skin mounting frame via an adsorption component lifting mechanism.

[0235] In some embodiments, the suction device lifting mechanism includes a lifting guide rod and a lifting drive unit. The lifting guide rod is arranged along the lifting direction and is used to mount the edge skin suction device. Specifically, the lifting guide rod is associated with the suction device mounting structure of the edge skin suction device. The lifting drive unit is used to drive the edge skin suction device to move up and down along the lifting guide rod. The lifting drive unit includes a drive motor and a lead screw assembly arranged along the lifting direction and driven by the drive motor. The drive motor and the lead screw assembly can be mounted on the suction device mounting structure. The drive motor can be located at one end of the lead screw assembly, which is controlled by the drive motor and associated with the suction device mounting frame of the edge skin suction device. Thus, when the edge skin lifting mechanism is used, the drive motor drives the lead screw assembly to rotate forward, thereby causing the suction device mounting frame and the edge skin suction device on it to move upward along the lifting guide rod; or, the drive motor drives the lead screw assembly to rotate in the reverse direction, thereby causing the suction device mounting frame and the edge skin suction device on it to move downward along the lifting guide rod. The suction device repositioning mechanism is used to drive the edge skin suction device to move along the repositioning direction to switch between multiple cutting stations.

[0236] In some embodiments, the adsorption element repositioning mechanism includes: an adsorption element repositioning guide rail and an adsorption element repositioning drive unit. The adsorption element repositioning guide rail is arranged on the edge skin mounting bracket along the repositioning direction. The adsorption element repositioning drive unit is associated with the edge skin adsorption element and is used to drive the associated edge skin adsorption element to move along the adsorption element repositioning guide rail. The repositioning direction is perpendicular to the transfer direction and forms a horizontal plane. Figure 1 The second direction, the Y-axis.

[0237] In some embodiments, the adsorption element repositioning drive unit includes: a repositioning gear, a drive gear, and a gear drive source. The repositioning gear is arranged along the repositioning direction, disposed on the edge skin adsorption element and meshing with the repositioning gear. The gear drive source is used to drive the drive gear to rotate so that the associated edge skin adsorption element moves along the repositioning direction.

[0238] In such Figure 1 and Figure 3 (or Figure 4 In the embodiment shown, the adsorption element repositioning drive unit includes: a repositioning gear rail, a drive gear, and a gear drive source. The repositioning gear rail is arranged along the repositioning direction, and its length in the repositioning direction covers at least the positions of the corresponding cutting stations and silicon rod cutting devices in the integrated cutting and grinding equipment for small-sized rectangular rods, ensuring that the adsorption element can be transferred to each cutting station. The moving gear rail can adopt a rack structure. The drive gear is located on the adsorption element mounting frame of the edge adsorption element and meshes with the repositioning gear rail. The gear drive source is located on the adsorption element mounting frame of the edge adsorption element and is associated with the drive gear. In practical applications, the gear drive source can be used to drive the drive gear to rotate, thereby moving the edge adsorption element along the repositioning direction via the repositioning gear rail. For example, the drive gear is driven to rotate forward by a gear drive source, and through the cooperation of the drive gear and the transposition gear, the associated silicon rod clamp moves forward in the transposition direction; the drive gear is driven to rotate in reverse by a gear drive source, and through the cooperation of the drive gear and the transposition gear, the associated silicon rod clamp moves backward in the transposition direction.

[0239] Of course, the structure of the adsorption element repositioning drive unit can still be varied. For example, in some embodiments, the adsorption element repositioning drive unit may include: a repositioning screw, arranged along the repositioning direction and associated with the adsorption element mounting bracket of the edge adsorption element; and a screw drive source for driving the repositioning screw to rotate so that the associated edge adsorption element moves along the repositioning direction. The chain conveying mechanism includes a ring chain and a chain drive source. The ring chain is associated with the adsorption element mounting bracket of the edge adsorption element. The ring chain may be, for example, a closed-loop chain, which is wound around a plurality of movable gears to form a preset shape. The chain drive source may be, for example, a servo motor.

[0240] In some embodiments, the half-bar cutting device of this application may also include an edge skin recycling box or an edge skin recycling vehicle, and the edge skin is unloaded into the edge skin recycling box or edge skin recycling vehicle by the edge skin unloading device 18.

[0241] The half-bar cutting equipment of this application may further include a feeding conveyor device located at the unloading area for conveying the ground half-bar. In some embodiments, the feeding conveyor device may be, for example, a conveyor belt device, including a conveyor belt wound around two front-to-back conveyor rollers, at least one of the two conveyor rollers being shaft-connected to a feeding drive source, which may be, for example, a servo motor. Figure 1 and Figure 2 (or Figure 4 In the embodiment shown, the half-bar grinding equipment further includes a feeding conveyor 179.

[0242] The integrated cutting and grinding equipment for small-sized rectangular rods in this application also includes a crystal wire detection device. In some embodiments, the crystal wire detection device includes: at least two support structures spaced apart, each support structure having a set of support rollers arranged along the transfer direction for supporting the silicon rod to be cut; a roller drive source for driving each support roller in the support roller set to rotate, thereby causing the silicon rod to be cut to rotate; and a crystal wire probe located between the at least two support structures.

[0243] At least two support structures are spaced apart along the transfer direction. Each support structure has a support roller assembly, wherein the support roller assembly includes two or more rollers arranged along the transfer direction. Rollers belonging to the same support roller assembly are connected by a rotating shaft arranged along the transfer direction. When the support roller assembly supports the silicon rod to be cut, the wheel surface of each roller in the support roller assembly contacts the silicon rod to be cut. Alternatively, in this embodiment, the at least two support structures spaced apart along the transfer direction can also be movable; that is, at least one of the bearing structures can move along the transfer direction to adjust the support spacing between the at least two support structures, adapting to support silicon rods of various sizes and specifications to be cut.

[0244] A roller drive source is used to drive the rotation of each support roller in the support roller assembly. The roller drive source may be, for example, a servo motor, which may be associated with at least one support roller assembly via, for example, a chain (set) or a gear set.

[0245] In practical applications, when a silicon rod with a circular cross-section is placed horizontally on the support structure of the crystal wire detection device, the axis of the silicon rod to be cut is aligned with the transfer direction. Then, the roller drive source can drive each support roller in the support roller group to rotate, so as to use the friction between the support roller and the silicon rod to be cut to drive the silicon rod to be cut to rotate, thus completing the crystal wire detection operation.

[0246] When using Figure 1 When the half-bar cutting device in the integrated cutting and grinding equipment for small-sized rectangular bars in the illustrated embodiment performs square cutting and halving operations, the specific process can be roughly as follows:

[0247] First, the silicon rod to be cut, which has a circular cross-section, is placed horizontally on the crystal wire detection device. The crystal wire detection device then rotates the silicon rod to be cut to complete the crystal wire detection operation.

[0248] Next, the silicon rod to be cut is picked up from the crystal line detection device and transferred to the first silicon rod transfer device corresponding to the first loading and unloading area of ​​the first cutting station using the silicon rod loading and unloading device. The silicon rod to be cut is placed horizontally and the axis of the silicon rod is consistent with the transfer direction.

[0249] Next, the edge clamping mechanism drives the edge clamping device to move forward along the forward and backward direction to the silicon rod, and drives the edge clamping device of the edge anti-breakage device corresponding to the first silicon rod transfer device to hold the silicon rod to be cut; the first silicon rod transfer device is driven to carry the silicon rod from the first loading and unloading area to the first cutting area along the transfer direction. The first silicon rod cutting device and the first silicon rod transfer device move relative to each other along the transfer direction. The two first cutting wire saws (the first cutting wire saws are arranged vertically or at an angle to the vertical) arranged opposite to each other in the first silicon rod cutting device perform the first cutting operation on the silicon rod to be cut carried by the first silicon rod transfer device, so that the silicon rod to be cut forms two parallel first side cut surfaces and two edge clamps.

[0250] Next, the edge skin clamping mechanism in the edge skin anti-breakage device is used to drive the edge skin clamp to retract in the forward and backward direction, thereby removing the edge skin held by the edge skin clamp in the forward and backward direction and causing the clamped edge skin to detach from the silicon rod body; the chuck driving mechanism in the edge skin clamp drives the chuck to move to release the clamped edge skin and place it on the edge skin bearing structure, driving the edge skin bearing structure to move the edge skin bearing structure and the edge skin it carries from the first cutting area to the first loading and unloading area; the edge skin flipping mechanism drives the edge skin bearing structure to flip; and the edge skin unloading device unloads the cut edge skin.

[0251] Next, the first silicon rod transfer device carries the silicon rod after the first cutting operation and moves away from the first cutting area along the transfer direction to the first loading and unloading area. The silicon rod loading and unloading device is used to clamp the silicon rod from the first silicon rod transfer device and move it along the conversion direction to the second cutting station. After rotating the silicon rod 90°, the silicon rod is placed on the second silicon rod transfer device located in the second loading and unloading area. The silicon rod is placed horizontally and the axis of the silicon rod is consistent with the transfer direction.

[0252] Next, the position of the silicon rod is adjusted using the centering adjustment mechanism in the silicon rod loading and unloading device so that the axis of the silicon rod corresponds to the predetermined center line.

[0253] Next, the edge clamp is driven by the edge clamp advance and retraction mechanism to advance to the silicon rod in the advance and retraction direction, and the edge clamp of the edge anti-breakage device corresponding to the second silicon rod transfer device is driven to hold the silicon rod; the second silicon rod transfer device is driven to carry the silicon rod from the second loading and unloading area to the second cutting area in the transfer direction. The second silicon rod cutting device and the second silicon rod transfer device move relative to each other in the transfer direction. The two second cutting wire saws (the second cutting wire saws are arranged vertically or at an angle to the vertical) and one third cutting wire saw (the third cutting wire saw is arranged vertically or at an angle to the vertical) arranged opposite to each other in the second silicon rod cutting device perform the second cutting operation on the silicon rod carried by the second silicon rod transfer device, so that the silicon rod is obtained by forming two parallel second side cut surfaces and at least one cutting surface located between the two second side cut surfaces, resulting in at least two half rods with a rectangular cross section.

[0254] Next, the edge skin clamping mechanism in the edge skin anti-breakage device is used to drive the edge skin clamp to retract in the forward and backward direction, thereby removing the edge skin held by the edge skin clamp in the forward and backward direction and causing the clamped edge skin to detach from the silicon rod body; the chuck driving mechanism in the edge skin clamp drives the chuck to move to release the clamped edge skin and place it on the edge skin bearing structure, driving the edge skin bearing structure to move the edge skin bearing structure and the edge skin it carries from the second cutting area to the second loading and unloading area; the edge skin flipping mechanism drives the edge skin bearing structure to flip; and the edge skin unloading device unloads the cut edge skin.

[0255] Next, the second silicon rod transfer device carries the two half rods after the second cutting operation and moves away from the first cutting area along the transfer direction to the first loading and unloading area. The silicon rod loading and unloading device is used to clamp the half rods from the second silicon rod transfer device and move them along the conversion direction to load the half rods into the half rod grinding equipment.

[0256] Regarding the half-bar grinding equipment, the half-bar grinding equipment 2 of this application includes: a grinding machine base, a grinding device, a chamfering device, and a half-bar transfer device.

[0257] The grinding machine base, as the main component of a semi-bar grinding machine, provides a processing platform. In practical applications, the grinding machine base is relatively large in size and weight to provide a large mounting surface and robust overall machine stability. It should be understood that the grinding machine base can serve as a seat for different structures or components performing processing operations within the semi-bar grinding machine, and the specific structure of the grinding machine base can be modified based on different functional or structural requirements. In some examples, the grinding machine base includes fixing or limiting structures for supporting different components within the semi-bar grinding machine, such as a base, column, or frame, all of which are grinding machine bases as described in this application.

[0258] Meanwhile, in some examples, the grinding base can be a single, integrated base, while in others, the grinding base can include multiple independent bases.

[0259] The grinding machine base has a grinding platform, which can be divided into multiple functional areas according to the specific work content of the half-bar grinding operation. For example, in some embodiments, the grinding platform includes a grinding area and a chamfering area. In some embodiments, the grinding platform includes a loading area, a grinding area, a chamfering area, and an unloading area. In some embodiments, the grinding platform includes a loading / unloading area, a grinding area, and a chamfering area. It should be noted that in the examples provided in this application, the functional areas are defined by the travel path and range of the processing device at the functional area. For example, the grinding device of the half-bar grinding equipment is located at the grinding area, and the range of the grinding area is the range occupied by the grinding device during the grinding operation; similarly, the chamfering device of the half-bar grinding equipment is located at the chamfering area, and the range of the chamfering area is the range occupied by the chamfering device during the chamfering operation. The shape of the grinding platform can be determined based on the grinding machine base, or it can be determined jointly based on the processing needs of the grinding machine base, the grinding device, and the chamfering device.

[0260] In some embodiments, the grinding platform includes a grinding area and a chamfering area. A grinding device, comprising at least one grinding tool, is located in the grinding area, and a chamfering device, comprising at least one chamfering tool, is located in the chamfering area. The grinding device, situated in the grinding area of ​​the grinding platform, is used to grind the sides of a half-bar located in the grinding area. Since the half-bar has four sides, the grinding device is used to grind all four sides of the half-bar.

[0261] In this application, the half-bar is placed horizontally in the grinding area of ​​the grinding platform. To ensure that the half-bar is stably placed in the grinding area, the half-bar grinding equipment of this application includes a first half-bar clamping device.

[0262] The first half-bar clamping device is located in the grinding area and is used to clamp the end of the half-bar along the length direction.

[0263] The first half-bar clamping device is intended to clamp the half-bar.

[0264] In some embodiments, the first half-bar clamping device includes: a first bearing mounting base and a first half-bar clamp.

[0265] A first support mounting base is disposed on the grinding machine base. In some embodiments, the first support mounting base is disposed on the grinding machine base along a first direction and is used to mount the first half-bar clamp.

[0266] The first half-bar clamp is used to clamp the half-bar. In some embodiments, the first half-bar clamp may include a first clamping base, at least one pair of first clamping members, and a first clamping member driving mechanism. The at least one pair of first clamping members are provided with a first clamping portion and a first clamping portion rotation mechanism. The at least one pair of first clamping members are disposed on opposite sides of the first clamping base and arranged along a first direction. The at least one pair of first clamping members are controlled by the first clamping member driving mechanism to clamp the two end faces of the half-bar, so that the clamped half-bar is placed horizontally along the first direction.

[0267] A first clamping member driving mechanism is used to drive at least one of a pair of first clamping members to move along a first direction to adjust the clamping distance between the pair of first clamping members. In some embodiments, two of the first clamping members in a pair are arranged opposite each other along the first direction, and the first clamping member driving mechanism can drive at least one of the first clamping members in the pair to move along the first direction to adjust the clamping distance between the oppositely arranged pair of first clamping members.

[0268] In some embodiments, the first clamping member driving mechanism may include an opening / closing guide rod and an opening / closing driving unit. The opening / closing guide rod is disposed on the clamping seat along a first direction for arranging a pair of first clamping members. The opening / closing driving unit is used to drive two of the pair of first clamping members to move towards each other or away from each other along the opening / closing guide rod disposed along the first direction. To ensure the stability of the first clamping members' horizontal movement along the first direction, the number of opening / closing guide rods may be multiple, for example, there may be two opening / closing guide rods. Of course, the number of opening / closing guide rods may also be other, for example, three, five, six, or more. Taking three as an example, the three opening / closing guide rods may be arranged in an isosceles triangle or an equilateral triangle, for example.

[0269] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder. One end of the horizontal telescopic rod is associated with a first clamping member, and the other end is associated with the telescopic cylinder, which is mounted on a first clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend or retract. For example, the telescopic cylinder can drive the horizontal telescopic rod to retract inward, causing one of the first clamping members in a pair to move towards the other first clamping member along an opening and closing guide rod arranged in a first direction, or causing the two first clamping members in a pair to move towards each other along the opening and closing guide rod arranged in the first direction, thereby reducing the clamping distance between the two first clamping members to clamp the half-rod located between the two first clamping members. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, causing one of the first clamping members in a pair to move away from the other first clamping member along an opening and closing guide rod arranged in the first direction, or causing the two first clamping members in a pair to move away from each other along the opening and closing guide rod arranged in the first direction, thereby increasing the clamping distance between the two first clamping members to release the clamped half-rod. Among them, telescopic cylinders can also be telescopic hydraulic cylinders.

[0270] In some embodiments, the opening / closing drive unit includes a lead screw and an opening / closing motor. One end of the lead screw (e.g., a threaded end) is associated with a first clamping member, and the other end of the lead screw is associated with the opening / closing motor, which is mounted on a first clamping seat. In practical applications, the opening / closing motor can drive the lead screw to rotate. For example, the opening / closing motor can drive the lead screw to rotate in the forward direction (or in the reverse direction), causing one of the first clamping members in a pair to move towards the other first clamping member along an opening / closing guide rod arranged in a first direction, or causing the two first clamping members in a pair to move towards each other along the opening / closing guide rod arranged in the first direction, thereby reducing the clamping distance between the two first clamping members to clamp the half-rod located between the two first clamping members. Correspondingly, the opening and closing motor drives the lead screw to rotate in the opposite direction (or drives the lead screw to rotate in the forward direction), driving one of the first clamping members in a pair of first clamping members to move away from the other first clamping member along the opening and closing guide rod set in the first direction, or driving the two first clamping members in a pair of first clamping members to move away from each other along the opening and closing guide rod set in the first direction, thereby increasing the clamping distance between the two first clamping members to release the clamped half rod.

[0271] In some embodiments, the opening and closing drive unit includes a bidirectional lead screw and an opening and closing motor. The bidirectional lead screw is arranged along a first direction and is a left-hand and right-hand lead screw. It has two threads on its body with opposite directions of rotation, i.e., one thread is a left-hand thread and the other thread is a right-hand thread. One thread can be associated with one first clamping member and the other thread can be associated with another first clamping member (e.g., the left-hand thread is associated with the first first clamping member and the right-hand thread is associated with the second first clamping member, or the right-hand thread is associated with the first first clamping member and the left-hand thread is associated with the second first clamping member). The opening and closing motor is associated with the bidirectional lead screw and is used to drive the bidirectional lead screw to rotate so that the two associated first clamping members move towards each other or away from each other along the opening and closing guide rod arranged along the first direction. In practical applications, for example, by using an opening and closing motor to drive the bidirectional lead screw to rotate forward (or reverse), the two associated first clamping members are driven to move towards each other (i.e., move closer to each other) along the opening and closing guide rod arranged in the first direction, reducing the clamping distance between the two first clamping members to clamp the half-bar located between the two first clamping members; or, by using an opening and closing motor to drive the bidirectional lead screw to rotate in the reverse direction (or forward), the two associated first clamping members are driven to move away from each other (i.e., move further apart) along the opening and closing guide rod arranged in the first direction, increasing the clamping distance between the two first clamping members to release the clamped half-bar. The opening and closing motor can be located in the middle section or at one end of the bidirectional lead screw. Thus, in this application, after the end of the half-bar along the length direction is clamped by the first half-bar clamping device, at least one side of the surface to be ground can be exposed.

[0272] In some embodiments, in the first half-bar clamping device, a first bearing mounting base is located at the bottom, and the clamping seat of the first half-bar clamp is located above the first bearing mounting base. At least one pair of first clamping members are located on the first clamping seat and face upwards. In some embodiments, after the at least one pair of first clamping members clamp the half-bar, the uppermost side can be fully exposed. The uppermost side serves as the side of the surface to be ground. Therefore, the grinding device at the grinding area may include at least one grinding wheel (e.g., one grinding wheel or two parallel grinding wheels), with the grinding surface of the at least one grinding wheel facing downwards. In some embodiments, after at least one pair of first clamping members clamp the half rod, the other three sides, except for the bottommost side adjacent to the clamping seat, are fully exposed. That is, the topmost side and its two adjacent left and right sides. Therefore, the three exposed sides are the sides of the surface to be ground. Thus, the grinding device at the grinding area may include multiple grinding tools. Some grinding tools have their grinding surfaces facing downwards, while others have their grinding surfaces facing left or right.

[0273] In some embodiments, in the first half-bar clamping device, a first bearing mounting base is located at the bottom and extends upward or is located on the side, and a first clamping seat of the first half-bar clamp is located on one side of the first bearing mounting base. At least one pair of first clamping members are located on the first clamping seat and are arranged facing left or right. In some embodiments, after at least one pair of first clamping members clamp the half-bar, the leftmost (or rightmost) side can be fully exposed. The leftmost (or rightmost) side is the side of the surface to be ground. Therefore, the grinding device at the grinding area may include at least one grinding tool (e.g., one grinding tool or two parallel grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing right (or horizontally facing left). In some embodiments, after at least one pair of first clamping members clamp the half bar, the other three sides, except for the rightmost (or leftmost) side adjacent to the clamping seat, are fully exposed. That is, the leftmost side and its two adjacent upper and lower sides. Therefore, the three exposed sides are the sides to be ground. Thus, the grinding device at the grinding area may include multiple grinding tools. Some grinding tools have their grinding surfaces horizontally facing to the right, while others have their grinding surfaces horizontally facing down or up.

[0274] In the foregoing description, regarding the side of the half-bar that is not exposed, in some embodiments, the position of the half-bar placed on the first half-bar clamping device can be changed by rotating or flipping it using other auxiliary fixtures (such as a half-bar transfer device) to expose the side that was not previously exposed.

[0275] Furthermore, in this application, the first half-bar clamping device may still have other variations. For example, in some embodiments, the first half-bar clamping device includes: a first clamping part disposed on the first clamping member and a first clamping part rotation mechanism for driving the first clamping part of the first clamping member to rotate. The first clamping part rotation mechanism can drive the first clamping part to rotate, thereby causing the half-bar clamped between the first clamping members to rotate to adjust the position of each side.

[0276] In some embodiments, in the first half-bar clamping device, a first bearing mounting base is located at the bottom, and a first clamping seat of the first half-bar clamp is located above the first bearing mounting base. At least one pair of first clamping members are located on the first clamping seat and face upwards. In some embodiments, after the at least one pair of first clamping members clamp the half-bar, the uppermost side can be fully exposed. The uppermost side serves as the side to be ground. Therefore, the grinding device at the grinding area may include at least one grinding wheel (e.g., one grinding wheel or two parallel grinding wheels), with the grinding surface of the at least one grinding wheel facing downwards. After the uppermost side has been ground by the grinding wheel, the first clamping part can be rotated (e.g., 90° or 180°) by the first clamping part rotation mechanism, which can then rotate the half-bar (e.g., 90° or 180°) to expose the other sides. The exposed other sides can still be ground by the grinding wheel. Thus, without changing the position of the grinding wheel, the first clamping part rotating mechanism drives the rotation of the half-bar to complete the grinding operation on each side of the half-bar.

[0277] In some embodiments, in the first half-bar clamping device, a first bearing mounting base is located at the bottom and extends upward or is located on the side. A first clamping seat of the first half-bar clamp is located on one side of the first bearing mounting base. At least one pair of first clamping members are located on the first clamping seat and are positioned to the left or right. In some embodiments, after the at least one pair of first clamping members clamp the half-bar, the leftmost (or rightmost) side can be fully exposed. The leftmost (or rightmost) side is the side to be ground. Therefore, the grinding device at the grinding area may include at least one grinding wheel (e.g., one grinding wheel or two parallel grinding wheels), with the grinding surface of the at least one grinding wheel facing horizontally to the right (or horizontally to the left). After the leftmost (or rightmost) side has been ground by the grinding wheel, the first clamping part can be rotated (e.g., 90° or 180°) by the first clamping part rotation mechanism, which in turn rotates the half-bar (e.g., 90° or 180°) to expose the other sides. The other exposed sides can still be ground by the grinding wheel. In this way, without changing the position of the grinding wheel, the grinding of each side of the half-bar is completed by rotating the first clamping part through the rotation mechanism.

[0278] In some embodiments, the first clamping part is a multi-point contact clamping head. Understandably, the contact method between the multi-point contact clamping head and the end face of the half rod is not limited to point contact. For example, the first clamping part may have multiple protrusions to contact the end face of the half rod, wherein each protrusion and the end face of the half rod may be in surface contact.

[0279] In some embodiments, the portions of one pair of first clamping members that contact the half-bar are configured as rigid structures to prevent the clamped half-bar from being disturbed during the grinding operation and affecting the machining accuracy.

[0280] In practical applications, the first clamping part rotation mechanism may include a rotatable structure disposed on two first clamping parts of a pair of first clamping members and a drive source for driving at least one of the two rotatable structures to rotate.

[0281] In some embodiments of this application, the first clamping part of the first clamping member may be configured as a rotatable frustum, the circular plane of which contacts the end face of the half-bar and remains relatively stationary after being pressed against the end face of the half-bar. The first clamping part also includes a locking structure, which locks the first clamping part when grinding a selected surface. During the switching between different grinding surfaces, the first clamping part rotates around the center of the frustum under the drive of the first clamping part rotation mechanism.

[0282] In some implementations, the first clamping part of the first clamping member includes a rotatable frustum and a series of protruding contacts disposed on the frustum. Each contact has a contact plane for contacting the clamped half-bar. The frustum rotates under the drive of the first clamping part's rotating mechanism. Regarding the contacts, in some implementations, the protrusion length of the contacts, i.e., their position on the horizontal line, is adjustable. This allows, during the clamping of the half-bar, for half-bars with low end-face flatness, the protrusion length of the contacts can be adjusted according to the half-bar's end face, ensuring that the contact surface of each contact is in close contact with the half-bar's end face. The protrusion length is the length of the horizontal line from the circular plane of the frustum to the contact plane of the contact.

[0283] The first clamping part rotation mechanism can be disposed on one of the first clamping members of a pair of first clamping members to drive the first clamping part of the pair of first clamping members to rotate with the clamped half rod; or, the first clamping part rotation mechanism can be disposed on both first clamping members of a pair of first clamping members and coordinately control the two first clamping parts of the pair of first clamping members to rotate at the same angle and in the same direction. In some implementations, the drive source in the first clamping part rotation mechanism can be, for example, a drive motor.

[0284] Regarding the grinding apparatus, the grinding apparatus includes a grinding frame and a grinding unit movably mounted on the grinding frame, or a pair of grinding units facing each other, each grinding unit having at least one grinding tool. In some embodiments, if the half-bar placed on the first half-bar clamping device exposes only one side, or if the half-bar exposes multiple sides but only one side needs to be ground at a time, then the grinding apparatus may include a grinding frame and a grinding unit movably mounted on the grinding frame, the grinding unit corresponding to the exposed side or the side to be ground. In some embodiments, if the half-bar placed on the first half-bar clamping device exposes at least a pair of facing sides, and both of these sides can be ground, then the grinding apparatus may include a grinding frame and a pair of grinding units movably mounted on the grinding frame facing each other, the pair of grinding units corresponding to the exposed pair of sides.

[0285] For a given grinding unit, the grinding unit includes a grinding support movably mounted on the grinding frame and at least one grinding tool mounted on the grinding support. In some embodiments, the grinding surface of the grinding tool is horizontally downward (or horizontally upward), then the grinding unit includes a grinding support movably mounted vertically on the grinding frame and at least one grinding tool mounted on the grinding support, the at least one grinding tool being used to perform grinding operations on the side surface of the half-bar held by the first half-bar clamping device.

[0286] A grinding support can be mounted vertically (i.e., in a third direction) on the grinding frame via a grinding support lifting mechanism. Using the grinding support lifting mechanism, the grinding support can move up and down relative to the grinding frame. In some embodiments, the grinding support lifting mechanism may include a grinding lifting guide rail and a grinding lifting drive unit, wherein the grinding lifting guide rail is vertically mounted on the grinding frame, and the grinding lifting drive unit is used to drive the grinding support and at least one grinding tool mounted thereon to move up and down along the grinding lifting guide rail. In some embodiments, the grinding lifting drive unit may include a grinding lifting screw and a drive source, the grinding lifting screw being vertically mounted and associated with the grinding support, and the drive source being used to drive the grinding lifting screw to rotate, causing the associated grinding support and at least one grinding tool mounted thereon to move up and down along the grinding lifting guide rail. In some examples, the drive source may be, for example, a drive motor. In some embodiments, the grinding support lifting mechanism may include a grinding lifting rack, a drive gear, and a drive source. The grinding lifting rack is vertically mounted on the grinding frame and parallel to the grinding lifting guide rail. The drive gear is mounted on the grinding support (e.g., at the bottom of the grinding support) and meshes with the grinding lifting rack. The drive source is associated with a drive wheel and is used to drive the drive wheel to rotate, causing the associated grinding support and at least one grinding tool mounted on it to move vertically along the grinding lifting guide rail. In some examples, the drive source may be, for example, a drive motor.

[0287] In some embodiments, the grinding surface of the grinding tool is vertically oriented to the left (or vertically oriented to the right), and the grinding unit includes a grinding support that is horizontally movably disposed on the grinding frame and at least one grinding tool disposed on the grinding support. The at least one grinding tool is used to perform grinding operations on the side of the half rod held by the first half rod clamping device.

[0288] A grinding support can be horizontally (e.g., in a second direction) mounted on a grinding frame via a grinding support advance / retreat mechanism. Using this mechanism, the grinding support can move forward and backward relative to the grinding frame. In some embodiments, the grinding support advance / retreat mechanism may include a grinding advance / retreat guide rail and a grinding advance / retreat drive unit, wherein the grinding advance / retreat guide rail is horizontally mounted on the grinding frame, and the grinding advance / retreat drive unit is used to drive the grinding support and at least one grinding tool mounted thereon to move forward and backward along the grinding advance / retreat guide rail. In some embodiments, the grinding advance / retreat drive unit may include a grinding lifting screw and a drive source, the grinding advance / retreat screw being horizontally mounted and associated with the grinding support, and the drive source being used to drive the grinding advance / retreat screw to rotate, causing the associated grinding support and at least one grinding tool mounted thereon to move forward and backward along the grinding advance / retreat guide rail. In some examples, the drive source may be, for example, a drive motor. In some embodiments, the grinding support retraction mechanism may include a grinding retraction rack, a drive gear, and a drive source. The grinding retraction rack is horizontally mounted on the grinding frame and parallel to the grinding retraction guide rail. The drive gear is mounted on the grinding support (e.g., at the bottom of the grinding support) and meshes with the grinding retraction rack. The drive source is associated with a drive wheel and is used to drive the drive wheel to rotate, causing the associated grinding support and at least one grinding tool mounted on it to move forward and backward along the grinding retraction guide rail. In some examples, the drive source may be, for example, a drive motor.

[0289] A grinding wheel includes at least one grinding wheel. For example, in some embodiments, a grinding apparatus includes a grinding wheel, which is either a coarse grinding wheel or a fine grinding wheel. In some embodiments, the grinding apparatus may include two grinding wheels arranged along a first direction, each grinding wheel including a grinding wheel; for example, the preceding grinding wheel includes a coarse grinding wheel, and the following grinding wheel includes a fine grinding wheel. In some embodiments, the grinding apparatus includes a grinding wheel comprising nested coarse and fine grinding wheels; for example, the coarse grinding wheel is nested within the fine grinding wheel, or the fine grinding wheel is nested within the coarse grinding wheel. The abrasive grain size of the fine grinding wheel is smaller than that of the coarse grinding wheel, and the abrasive grain density of the fine grinding wheel is greater than that of the coarse grinding wheel.

[0290] When a grinding wheel includes a coarse grinding wheel and a fine grinding wheel, it can be used to perform both coarse and fine grinding operations on the side of a half-bar. Therefore, at least one of the coarse grinding wheel and the fine grinding wheel is equipped with a telescopic drive mechanism. For example, when the coarse grinding wheel is nested within the fine grinding wheel, the coarse grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the coarse grinding wheel to extend and protrude beyond the fine grinding wheel, allowing the protruding coarse grinding wheel to perform coarse grinding on the side of the half-bar. During fine grinding, the telescopic drive mechanism drives the coarse grinding wheel to retract and recess into the fine grinding wheel, allowing the fine grinding wheel to perform fine grinding on the side of the half-bar. Alternatively, when a coarse grinding wheel is nested within a fine grinding wheel, the fine grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the fine grinding wheel to retract and recess into the coarse grinding wheel, allowing the coarse grinding wheel to perform coarse grinding on the side of the half-bar. During fine grinding, the telescopic drive mechanism drives the fine grinding wheel to extend and protrude from the coarse grinding wheel, allowing the protruding fine grinding wheel to perform fine grinding on the side of the half-bar. For example, when a fine grinding wheel is nested within a coarse grinding wheel, the coarse grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the coarse grinding wheel to extend and protrude from the fine grinding wheel, allowing the protruding coarse grinding wheel to perform coarse grinding on the side of the half-bar. During fine grinding, the telescopic drive mechanism drives the coarse grinding wheel to retract and recess into the fine grinding wheel, allowing the fine grinding wheel to perform fine grinding on the side of the half-bar. Alternatively, when the fine grinding wheel is nested inside the coarse grinding wheel, the fine grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the fine grinding wheel to retract and recess into the coarse grinding wheel, so that the coarse grinding wheel can be used to perform coarse grinding on the side of the half-bar. During fine grinding, the telescopic drive mechanism drives the fine grinding wheel to extend and protrude from the coarse grinding wheel, so that the protruding fine grinding wheel can be used to perform fine grinding on the side of the half-bar.

[0291] In this application, when grinding the side surface of a half-bar, the grinding device grinds the side surface of the half-bar held by the first half-bar clamping device by driving the grinding device and the first half-bar clamping device to move relative to each other in a first direction. Therefore, in some embodiments, the grinding device is a movable grinding device and the first half-bar clamping device is a fixed half-bar clamping device. In some embodiments, the grinding device is a fixed grinding device and the first half-bar clamping device is a movable half-bar clamping device. In some embodiments, the grinding device is a movable grinding device and the first half-bar clamping device is a movable half-bar clamping device. Taking a movable grinding device as an example, the grinding device includes a grinding frame traveling mechanism, which drives the grinding frame and its grinding units to move along the first direction.

[0292] In some embodiments, the grinding frame traveling mechanism includes a grinding traveling guide rail and a grinding traveling drive unit, wherein the grinding traveling guide rail is disposed on the grinding machine base along a first direction, and the grinding traveling drive unit is used to drive the grinding frame and the grinding unit thereon to move along the grinding traveling guide rail.

[0293] In some embodiments, the grinding travel drive unit includes a grinding travel rack, a drive gear, and a drive source. The grinding travel rack is disposed on the grinding machine base along a first direction and parallel to the grinding travel guide rail. The drive gear is disposed on the grinding frame (e.g., at the bottom of the grinding frame) and meshes with the grinding travel rack. The drive gear is driven to rotate by the drive source, and its teeth mesh with the grinding travel rack, traveling in accordance with the grinding travel rack. The grinding frame connected to the drive gear and the grinding units it houses move along the grinding travel guide rail. The drive source is, for example, a drive motor.

[0294] In some embodiments, the grinding travel drive unit includes a grinding travel screw and a drive source, wherein the grinding travel screw is arranged along a first direction and associated with the grinding frame, and the drive source is used to drive the grinding travel screw to rotate so that the associated grinding frame and its grinding unit move along the grinding travel guide rail. The drive source is, for example, a drive motor.

[0295] When the grinding device is used to grind the side of the half rod in the grinding area, the grinding frame and its grinding unit are driven by the grinding frame traveling mechanism to move in the first direction so as to achieve relative movement with the half rod held by the first half rod clamping device in the grinding area so that the grinding wheel in the grinding unit can grind the side of the half rod held by the first half rod clamping device in the grinding area.

[0296] Taking a mobile half-bar clamping device as an example, the first half-bar clamping device includes a first clamping travel mechanism, which drives the first half-bar clamping device and the half-bar it clamps to move along a first direction.

[0297] In some embodiments, the first clamping travel mechanism includes: a first clamping travel guide rail and a first clamping travel drive unit, wherein the first clamping travel guide rail is disposed on the first bearing mounting base along a first direction, and the first clamping travel drive unit is used to drive the first half-bar clamp and the half-bar it clamps to move along the first clamping travel guide rail.

[0298] In some embodiments, the first clamping travel drive unit includes a first clamping travel rack, a drive gear, and a drive source. The first clamping travel rack is disposed on a first bearing mounting base along a first direction and parallel to a first clamping travel guide rail. The drive gear is disposed on a first half-bar clamp and meshes with the first clamping travel guide rail. The drive gear is driven to rotate by the drive source, and its teeth mesh with the first clamping travel guide rail, causing it to travel along the first clamping travel guide rail. The first half-bar clamp connected to the drive gear and the half-bar it clamps move along the first clamping travel guide rail. The drive source is, for example, a drive motor.

[0299] In some embodiments, the first clamping travel drive unit includes a first clamping travel screw and a drive source, wherein the first clamping travel screw is arranged along a first direction and associated with a first half-bar clamp, and the drive source is used to drive the first clamping travel screw to rotate so that the associated first half-bar clamp and the half-bar it clamps move along the first clamping travel guide rail.

[0300] When the grinding device is used to grind the side of the half rod in the grinding area, the first clamping and traveling mechanism drives the first half rod clamp and the half rod it clamps to move along the first direction so as to achieve relative movement with the grinding unit in the grinding device so that the grinding wheel in the grinding unit can grind the side of the first half rod clamp and the half rod it clamps.

[0301] The chamfering device is located in the chamfering area of ​​the grinding platform and is used to chamfer the edges of the half-bar located in the chamfering area. The half-bar has four edges, therefore, the chamfering device is used to chamfer the four edges of the half-bar.

[0302] In this application, the half-bar is placed horizontally in the chamfered area of ​​the grinding platform.

[0303] In some embodiments, the half-bar grinding apparatus of this application includes a third half-bar clamping device. The third half-bar clamping device is located in the chamfering area and is used to clamp the end of the half-bar along its length.

[0304] The third half-bar clamping device is intended to clamp a half-bar. In some embodiments, the third half-bar clamping device includes a third bearing mounting base and a third half-bar clamp. In some embodiments, the third half-bar clamping device clamps the half-bar such that the half-bar is placed horizontally and its length direction is aligned with a first direction. In some embodiments, the third half-bar clamping device clamps the half-bar such that the half-bar is placed horizontally and its length direction is aligned with a second direction.

[0305] In the following description, an example is given where a half-bar is placed horizontally in the chamfered area and the length direction of the half-bar is consistent with the first direction.

[0306] The third support mounting base is disposed on the grinding machine base. In some embodiments, the third support mounting base is disposed on the grinding machine base along the first direction and is used to mount the third half-bar clamp.

[0307] The third half-bar clamp is used to hold the half-bar. In some embodiments, the third half-bar clamp may include a third clamping base, at least one pair of third clamping members, and a third clamping member driving mechanism. The at least one pair of third clamping members are provided with a third clamping portion and a third clamping portion rotation mechanism. The at least one pair of third clamping members are disposed on opposite sides of the third clamping base and arranged along a first direction. The at least one pair of third clamping members are controlled by the third clamping member driving mechanism to clamp the two end faces of the half-bar, so that the clamped half-bar is placed horizontally along the first direction.

[0308] The third clamping member driving mechanism is used to drive at least one of the at least one pair of third clamping members to move along a first direction to adjust the clamping distance between the pair of third clamping members. In some embodiments, two of the third clamping members in a pair are arranged opposite each other along the first direction, and the third clamping member driving mechanism can drive at least one of the third clamping members in the pair to move along the first direction to adjust the clamping distance between the oppositely arranged pair of third clamping members.

[0309] In some embodiments, the third clamping member driving mechanism may include an opening / closing guide rod and an opening / closing driving unit. The opening / closing guide rod is disposed on the clamping seat along a first direction for mounting a pair of third clamping members. The opening / closing driving unit is used to drive two of the pair of third clamping members to move towards each other or away from each other along the opening / closing guide rod disposed along the first direction. To ensure the stability of the third clamping members' horizontal movement along the first direction, the number of opening / closing guide rods may be multiple, for example, there may be two opening / closing guide rods. Of course, the number of opening / closing guide rods may also be other, for example, three, five, six, or more. Taking three as an example, the three opening / closing guide rods may be arranged in an isosceles triangle or an equilateral triangle, for example.

[0310] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder. One end of the horizontal telescopic rod is associated with a third clamping member, and the other end is associated with the telescopic cylinder, which is mounted on a third clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend or retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, causing one of the third clamping members in a pair to move towards the other third clamping member along an opening and closing guide rod arranged in a first direction, or causing the two third clamping members in a pair to move towards each other along the opening and closing guide rod arranged in the first direction, thereby reducing the clamping distance between the two third clamping members to clamp the half-rod located between the two third clamping members. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, causing one of the third clamping members in a pair to move away from the other third clamping member along an opening and closing guide rod arranged in the first direction, or causing the two third clamping members in a pair to move away from each other along the opening and closing guide rod arranged in the first direction, thereby increasing the clamping distance between the two third clamping members to release the clamped half-rod. Among them, telescopic cylinders can also be telescopic hydraulic cylinders.

[0311] In some embodiments, the opening / closing drive unit includes a lead screw and an opening / closing motor. One end of the lead screw (e.g., a threaded end) is associated with a third clamping member, and the other end of the lead screw is associated with the opening / closing motor, which is mounted on a third clamping seat. In practical applications, the opening / closing motor can drive the lead screw to rotate. For example, the opening / closing motor drives the lead screw to rotate in the forward direction (or in the reverse direction), causing one of the third clamping members in a pair to move towards the other third clamping member along an opening / closing guide rod arranged in a first direction, or causing the two third clamping members in a pair to move towards each other along the opening / closing guide rod arranged in the first direction, thereby reducing the clamping distance between the two third clamping members to clamp the half-rod located between the two third clamping members. Correspondingly, the opening and closing motor drives the lead screw to rotate in the opposite direction (or drives the lead screw to rotate in the forward direction), driving one of the third clamping members in a pair to move away from the other third clamping member along the opening and closing guide rod set in the first direction, or driving the two third clamping members in a pair to move away from each other along the opening and closing guide rod set in the first direction, increasing the clamping distance between the two third clamping members to release the clamped half rod.

[0312] In some embodiments, the opening and closing drive unit includes a bidirectional lead screw and an opening and closing motor. The bidirectional lead screw is arranged along a first direction and is a left-hand and right-hand lead screw. It has two sections of threads on its body with opposite directions of rotation, i.e., one section of thread is a left-hand thread and the other section of thread is a right-hand thread. One section of thread can be associated with one third clamping member and the other section of thread can be associated with another third clamping member (for example, the left-hand thread is associated with the first third clamping member and the right-hand thread is associated with the second third clamping member, or the right-hand thread is associated with the first third clamping member and the left-hand thread is associated with the second third clamping member). The opening and closing motor is associated with the bidirectional lead screw and is used to drive the bidirectional lead screw to rotate so that the two associated third clamping members move towards each other or away from each other along the opening and closing guide rod arranged along the first direction. In practical applications, for example, by using an opening and closing motor to drive the bidirectional lead screw to rotate forward (or reverse), the two associated third clamping members are driven to move towards each other (i.e., move closer to each other) along the opening and closing guide rod set in the first direction, reducing the clamping distance between the two third clamping members to clamp the half-bar located between the two third clamping members; or, by using an opening and closing motor to drive the bidirectional lead screw to rotate in the reverse direction (or forward), the two associated third clamping members are driven to move away from each other (i.e., move further apart) along the opening and closing guide rod set in the first direction, increasing the clamping distance between the two third clamping members to release the clamped half-bar. The opening and closing motor can be located in the middle section or at one end of the bidirectional lead screw.

[0313] Thus, in this application, after the end of the half-bar along the length direction is clamped by the third half-bar clamping device, at least one edge to be chamfered can be exposed. In some embodiments, in the third half-bar clamping device, the third bearing mounting base is located at the bottom, the clamping seat of the third half-bar clamp is located above the third bearing mounting base, and at least one pair of third clamping members are located on the third clamping seat and face upwards. In some embodiments, after the at least one pair of third clamping members clamp the half-bar, the uppermost edge can be fully exposed, and the uppermost edge is the edge to be chamfered. Therefore, the chamfering device at the chamfering area may include at least one chamfering tool (e.g., one chamfering tool or two parallel chamfering tools), and the chamfering surface of the at least one chamfering tool faces downwards. In some embodiments, after at least one pair of third clamping members clamp the half-bar, the two edges arranged horizontally and vertically above are fully exposed (at this time, the sides of the half-bar are arranged horizontally or vertically). That is, the two exposed edges serve as the edges to be chamfered. Therefore, the chamfering device at the chamfering area may include a pair of chamfering tools arranged at an angle. For example, in one example, one of the chamfering tools is at a 45° angle to the horizontal or vertical line, and the other chamfering tool is at a 45° angle to the horizontal or vertical line. Of course, the above-mentioned angle is not limited to this. In different embodiments, other angles may be selected. For example, the angle may be any angle from 40° to 60°, and is not limited to integer degrees.

[0314] In some embodiments, in the third half-bar clamping device, the third bearing mounting base is located at the bottom and extends upward or is located on the side, and the third clamping seat of the third half-bar clamp is located on one side of the third bearing mounting base. At least one pair of third clamping members are located on the third clamping seat and are arranged facing left or right. In some embodiments, after at least one pair of third clamping members clamp the half-bar, the leftmost (or rightmost) edge is fully exposed. The leftmost (or rightmost) edge is the edge to be chamfered. Therefore, the chamfering device at the chamfering area may include at least one chamfering tool (e.g., one chamfering tool or two parallel chamfering tools), and the chamfering surface of the at least one chamfering tool faces horizontally to the right (or horizontally to the left). In some embodiments, after at least one pair of third clamping members clamp the half-bar, two vertically arranged edges located on the left (or right) side are fully exposed (in this case, the sides of the half-bar are arranged horizontally or vertically). That is, the two exposed edges serve as the edges to be chamfered. Therefore, the chamfering device at the chamfering area may include a pair of chamfering molds arranged at an angle. For example, in one example, one of the chamfering molds is at a 45° angle to the horizontal or vertical line, and the other chamfering mold is at a 45° angle to the horizontal or vertical line. Of course, the above-mentioned angle is not limited to this. In different embodiments, other angles may be selected. For example, the angle may be any angle from 40° to 60°, and is not limited to integer degrees.

[0315] In the foregoing description, for the edges that are not exposed in the half-bar, in some embodiments, the position of the half-bar placed on the third half-bar clamping device can be changed by rotating or flipping the half-bar through other auxiliary fixtures (such as half-bar transfer device, etc.) so as to expose the edges that were not previously exposed.

[0316] Furthermore, in this application, the third half-bar clamping device may still have other variations. For example, in some embodiments, the third half-bar clamping device includes: a third clamping part disposed on the third clamping member and a third clamping part rotation mechanism for driving the third clamping part of the third clamping member to rotate. By using the third clamping part rotation mechanism to drive the third clamping part to rotate, the half-bars clamped between the third clamping members can be rotated to adjust the position of each edge.

[0317] In some embodiments, in the third half-bar clamping device, the third bearing mounting base is located at the bottom, and the third clamping seat of the third half-bar clamp is located above the third bearing mounting base. At least one pair of third clamping members are located on the third clamping seat and face upwards. In some embodiments, after the at least one pair of third clamping members clamp the half-bar, the uppermost edge can be fully exposed. The uppermost edge serves as the edge to be chamfered. Therefore, the chamfering device at the chamfering area may include at least one chamfering tool (e.g., one chamfering tool or two parallel chamfering tools), with the chamfering surface of the at least one chamfering tool facing downwards. After the uppermost edge has been chamfered by the chamfering tool, the third clamping part can be rotated by the third clamping part rotation mechanism to rotate the half-bar, thereby exposing the other edges. The exposed other edges can still be chamfered by the chamfering tool. Thus, without changing the position of the chamfering die, the rotation of the half-bar is driven by the rotation mechanism of the third clamping part to complete the chamfering operation of each edge of the half-bar.

[0318] In some embodiments, in the third half-bar clamping device, the third bearing mounting base is located at the bottom and extends upward or is located on the side. The third clamping seat of the third half-bar clamp is located on one side of the third bearing mounting base, and at least one pair of third clamping members are located on the third clamping seat and are arranged facing left or right. In some embodiments, after at least one pair of third clamping members clamp the half-bar, the leftmost (or rightmost) edge can be fully exposed. The leftmost (or rightmost) edge is the edge to be chamfered. Therefore, the chamfering device at the chamfering area may include at least one chamfering tool (e.g., one chamfering tool or two parallel chamfering tools), with the chamfering surface of the at least one chamfering tool facing horizontally to the right (or horizontally to the left). After the leftmost (or rightmost) edge has been chamfered by the chamfering tool, the third clamping part can be rotated by the third clamping part rotation mechanism to rotate the half-bar, thereby exposing the other edges. The exposed other edges can still be chamfered by the chamfering tool. Thus, without changing the position of the chamfering die, the rotation of the half-bar is driven by the rotation mechanism of the third clamping part to complete the chamfering operation of each edge of the half-bar.

[0319] In some embodiments, the third clamping part is a multi-point contact clamping head. Understandably, the contact method between the multi-point contact clamping head and the end face of the half rod is not limited to point contact. For example, the third clamping part may have multiple protrusions to contact the end face of the half rod, wherein each protrusion and the end face of the half rod may be in surface contact.

[0320] In some embodiments, the portions of one of the third clamping members that contact the half-bar are configured as rigid structures to prevent the clamped half-bar from being disturbed during the chamfering operation and affecting the machining accuracy.

[0321] In practical applications, the third clamping part rotation mechanism may include a rotatable structure disposed on two third clamping parts in a pair of third clamping members, and a drive source for driving at least one of the two rotatable structures to rotate.

[0322] In some embodiments of this application, the third clamping part of the third clamping member can be configured as a rotatable frustum, the circular plane of which contacts the end face of the half-bar and remains relatively stationary after being pressed against the end face of the half-bar. The third clamping part also includes a locking structure, which locks the third clamping part when a selected plane is chamfered. During the switching of different chamfers, the third clamping part rotates around the center of the frustum under the drive of the third clamping part rotation mechanism.

[0323] In some implementations, the third clamping part of the third clamping member includes a rotatable frustum and a series of protruding contacts disposed on the frustum. Each contact has a contact plane for contacting the clamped half-bar. The frustum rotates under the drive of the rotating mechanism of the third clamping part. Regarding the contacts, in some implementations, the protrusion length of the contacts, i.e., their position on the horizontal line, is adjustable. This allows the protrusion length of the contacts to be adjusted according to the end face of the half-bar during clamping, especially for half-bars with low end face flatness, ensuring that the contact surface of each contact is in close contact with the end face of the half-bar. The protrusion length is the length of the horizontal line from the circular plane of the frustum to the contact plane of the contact.

[0324] The third clamping part rotation mechanism can be disposed on one of the third clamping members in a pair of third clamping members, so as to drive the third clamping part of the pair of third clamping members and the clamped half rod to rotate; or, the third clamping part rotation mechanism can be disposed on both third clamping members of a pair of third clamping members, and coordinately control the two third clamping parts of the pair of third clamping members to rotate at the same angle and in the same direction. In some implementations, the drive source in the third clamping part rotation mechanism can be, for example, a drive motor.

[0325] Regarding the chamfering device, the chamfering device includes a chamfering frame and a chamfering unit movably mounted on the chamfering frame, or a pair of chamfering units facing each other, each chamfering unit having at least one chamfering die. In some embodiments, if the half-bar placed on the third half-bar clamping device exposes only one edge, or if the half-bar exposes multiple edges but only one edge needs to be chamfered at a time, then the chamfering device may include a chamfering frame and a chamfering unit movably mounted on the chamfering frame, the chamfering unit corresponding to the exposed edge or the edge that needs to be chamfered. In some embodiments, if the half-bar placed on the third half-bar clamping device exposes at least one pair of edges (i.e., two edges adjacent to a certain side) and both of these edges can be chamfered, then the chamfering device may include a chamfering frame and a pair of chamfering units movably mounted on the chamfering frame at an angle, the pair of chamfering units corresponding to the exposed pair of edges.

[0326] For a given chamfering unit, the chamfering unit includes a chamfering support movably mounted on the chamfering frame and at least one chamfering tool mounted on the chamfering support. In some embodiments, the chamfering surface of the chamfering tool is horizontally downward or horizontally upward (or, if there is a pair of chamfering tools, the chamfering tools are angled downward or angled upward), then the chamfering unit includes a chamfering support movably mounted vertically on the chamfering frame and at least one chamfering tool mounted on the chamfering support, the at least one chamfering tool being used to chamfer the edge of the half-bar held by the third half-bar clamping device.

[0327] A chamfering support can be mounted vertically (i.e., in the third direction) on a chamfering frame via a chamfering support lifting mechanism. Using this lifting mechanism, the chamfering support can move vertically relative to the chamfering frame. In some embodiments, the chamfering support lifting mechanism may include a chamfering lifting guide rail and a chamfering lifting drive unit, wherein the chamfering lifting guide rail is vertically mounted on the chamfering frame, and the chamfering lifting drive unit drives the chamfering support and at least one chamfering die mounted thereon to move vertically along the chamfering lifting guide rail. In some embodiments, the chamfering lifting drive unit may include a chamfering lifting screw and a drive source, wherein the chamfering lifting screw is vertically mounted and associated with the chamfering support, and the drive source drives the chamfering lifting screw to rotate, causing the associated chamfering support and at least one chamfering die mounted thereon to move vertically along the chamfering lifting guide rail. In some examples, the drive source may be, for example, a drive motor. In some embodiments, the chamfering support lifting mechanism may include a chamfering lifting rack, a drive gear, and a drive source. The chamfering lifting rack is vertically mounted on the chamfering frame and parallel to the chamfering lifting guide rail. The drive gear is mounted on the chamfering support (e.g., at the bottom of the chamfering support) and meshes with the chamfering lifting rack. The drive source is associated with a drive wheel and is used to drive the drive wheel to rotate, causing the associated chamfering support and at least one chamfering die mounted on it to move vertically along the chamfering lifting guide rail. In some examples, the drive source may be, for example, a drive motor.

[0328] In some embodiments, the chamfering face of the chamfering tool is perpendicular to the left or right (if it is a pair of chamfering tools, the chamfering face of the chamfering tool is angled to the left or angled to the right). The chamfering unit includes a chamfering support that is horizontally movably disposed on the chamfering frame and at least one chamfering tool disposed on the chamfering support. The at least one chamfering tool is used to chamfer the edge of the half rod held by the third half rod clamping device.

[0329] A chamfering support can be horizontally (e.g., in a second direction) mounted on a chamfering frame via a chamfering support retraction mechanism. Using this mechanism, the chamfering support can move forward and backward relative to the chamfering frame. In some embodiments, the chamfering support retraction mechanism may include a chamfering retraction guide rail and a chamfering retraction drive unit, wherein the guide rail is horizontally mounted on the chamfering frame, and the drive unit drives the chamfering support and at least one chamfering die mounted thereon to move forward and backward along the guide rail. In some embodiments, the drive unit may include a chamfering lifting screw and a drive source, the screw being horizontally mounted and associated with the chamfering support, and the drive source driving the screw to rotate so that the associated chamfering support and at least one chamfering die mounted thereon move forward and backward along the guide rail. In some examples, the drive source may be, for example, a drive motor. In some embodiments, the chamfering support retraction mechanism may include a chamfering retraction rack, a drive gear, and a drive source. The chamfering retraction rack is horizontally mounted on the chamfering bracket and parallel to the chamfering retraction guide rail. The drive gear is mounted on the chamfering support (e.g., at the bottom of the chamfering support) and meshes with the chamfering retraction rack. The drive source is associated with a drive wheel and is used to drive the drive wheel to rotate, causing the associated chamfering support and at least one chamfering die mounted on it to move forward and backward along the chamfering retraction guide rail. In some examples, the drive source may be, for example, a drive motor.

[0330] In some embodiments, the chamfered surface of the chamfering tool is angled. The chamfering unit includes a chamfering support and at least one chamfering tool disposed on the chamfering support. The chamfering unit can be translated by a horizontal (e.g., a second direction) chamfering support translation mechanism, or moved vertically by a vertical chamfering support lifting mechanism, or moved forward and backward by a chamfering support retraction mechanism perpendicular to the chamfered surface. For details regarding the chamfering support translation mechanism, chamfering support lifting mechanism, and chamfering support retraction mechanism, please refer to the description of the aforementioned related structures; further details will not be repeated here.

[0331] A chamfering tool includes at least one grinding wheel. For example, in some embodiments, a chamfering device includes a chamfering tool, which includes a grinding wheel, either a coarse grinding wheel or a fine grinding wheel. In some embodiments, a chamfering device may include two chamfering tools arranged along a first direction, each chamfering tool including a grinding wheel; for example, the preceding chamfering tool includes a coarse grinding wheel, and the following chamfering tool includes a fine grinding wheel. In some embodiments, a chamfering device includes a chamfering tool comprising nested coarse and fine grinding wheels; for example, the coarse grinding wheel is nested within the fine grinding wheel, or the fine grinding wheel is nested within the coarse grinding wheel. The abrasive grain size of the fine grinding wheel is smaller than that of the coarse grinding wheel, and the abrasive grain density of the fine grinding wheel is greater than that of the coarse grinding wheel.

[0332] When a chamfering abrasive includes a coarse grinding wheel and a fine grinding wheel, it can be used to perform both coarse and fine chamfering operations on the edges of a half-bar. Therefore, at least one of the coarse grinding wheel and the fine grinding wheel is equipped with a telescopic drive mechanism. For example, when the coarse grinding wheel is nested within the fine grinding wheel, the coarse grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the coarse grinding wheel to extend and protrude beyond the fine grinding wheel, allowing the protruding coarse grinding wheel to perform coarse chamfering on the edges of the half-bar. During fine grinding, the telescopic drive mechanism drives the coarse grinding wheel to retract and recess into the fine grinding wheel, allowing the fine grinding wheel to perform fine chamfering on the edges of the half-bar. Alternatively, when a coarse grinding wheel is nested within a fine grinding wheel, the fine grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the fine grinding wheel to retract and recess into the coarse grinding wheel, allowing the coarse grinding wheel to perform a rough chamfer on the edges of the half-bar. During fine grinding, the telescopic drive mechanism drives the fine grinding wheel to extend and protrude from the coarse grinding wheel, allowing the protruding fine grinding wheel to perform a fine chamfer on the edges of the half-bar. For example, when a fine grinding wheel is nested within a coarse grinding wheel, the coarse grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the coarse grinding wheel to extend and protrude from the fine grinding wheel, allowing the protruding coarse grinding wheel to perform a rough chamfer on the edges of the half-bar. During fine grinding, the telescopic drive mechanism drives the coarse grinding wheel to retract and recess into the fine grinding wheel, allowing the fine grinding wheel to perform a fine chamfer on the edges of the half-bar. Alternatively, when the fine grinding wheel is nested inside the coarse grinding wheel, the fine grinding wheel can be equipped with a telescopic drive mechanism. During coarse grinding, the telescopic drive mechanism drives the fine grinding wheel to retract and recess into the coarse grinding wheel, so that the coarse grinding wheel can be used to perform a rough chamfering operation on the edge of the half-bar. During fine grinding, the telescopic drive mechanism drives the fine grinding wheel to extend and protrude from the coarse grinding wheel, so that the protruding fine grinding wheel can be used to perform a fine chamfering operation on the edge of the half-bar.

[0333] In this application, when chamfering the edge of a half-bar, the chamfering device performs the chamfering operation on the edge of the half-bar held by the third half-bar clamping device by driving the chamfering device and the third half-bar clamping device to move relative to each other in a first direction. Therefore, in some embodiments, the chamfering device is a movable chamfering device and the third half-bar clamping device is a fixed half-bar clamping device. In some embodiments, the chamfering device is a fixed chamfering device and the third half-bar clamping device is a movable half-bar clamping device. In some embodiments, the chamfering device is a movable chamfering device and the third half-bar clamping device is a movable half-bar clamping device. Taking a movable chamfering device as an example, the chamfering device includes a chamfering frame traveling mechanism, which drives the chamfering frame and its chamfering units to move along the first direction.

[0334] In some embodiments, the chamfering frame traveling mechanism includes a chamfering traveling guide rail and a chamfering traveling drive unit, wherein the chamfering traveling guide rail is disposed on the grinding machine base along a first direction, and the chamfering traveling drive unit is used to drive the chamfering frame and the chamfering unit disposed thereon to move along the chamfering traveling guide rail.

[0335] In some embodiments, the chamfering travel drive unit includes a chamfering travel rack, a drive gear, and a drive source. The chamfering travel rack is disposed on the grinding machine base along a first direction and parallel to the chamfering travel guide rail. The drive gear is disposed on the chamfering frame (e.g., at the bottom of the chamfering frame) and meshes with the chamfering travel rack. The drive gear is driven to rotate by the drive source, and its teeth mesh with the chamfering travel rack, moving in accordance with the chamfering travel rack. The chamfering frame connected to the drive gear and the chamfering units thereon move along the chamfering travel guide rail. The drive source is, for example, a drive motor.

[0336] In some embodiments, the chamfering travel drive unit includes a chamfering travel screw and a drive source, wherein the chamfering travel screw is arranged along a first direction and associated with a chamfering frame, and the drive source is used to drive the chamfering travel screw to rotate so that the associated chamfering frame and its chamfering units move along the chamfering travel guide. The drive source is, for example, a drive motor.

[0337] When using a chamfering device to chamfer the edge of a half-bar in the chamfering area, the chamfering frame and its chamfering unit are driven by the chamfering frame traveling mechanism to move in the first direction so as to achieve relative movement with the half-bar held by the third half-bar clamping device in the chamfering area so that the chamfering die in the chamfering unit can chamfer the edge of the half-bar held by the third half-bar clamping device in the chamfering area.

[0338] Taking a movable half-bar clamping device as an example, the third half-bar clamping device includes a third clamping travel mechanism, which drives the third half-bar clamping device and the half-bar it clamps to move along a first direction. In some embodiments, the third clamping travel mechanism includes a third clamping travel guide rail and a third clamping travel drive unit, wherein the third clamping travel guide rail is disposed on a third bearing mounting base along the first direction, and the third clamping travel drive unit is used to drive the third half-bar clamp and the half-bar it clamps to move along the third clamping travel guide rail.

[0339] In some embodiments, the third clamping travel drive unit includes a third clamping travel rack, a drive gear, and a drive source. The third clamping travel rack is disposed on a third bearing mounting base along a first direction and parallel to the third clamping travel guide rail. The drive gear is disposed on the third half-bar clamp and meshes with the third clamping travel guide rail. The drive gear is driven to rotate by the drive source, and its teeth mesh with the third clamping travel guide rail, causing it to travel along the guide rail. The third half-bar clamp connected to the drive gear and the half-bar it clamps move along the third clamping travel guide rail. The drive source is, for example, a drive motor.

[0340] In some embodiments, the third clamping travel drive unit includes a third clamping travel screw and a drive source, wherein the third clamping travel screw is arranged along a first direction and associated with a third half-bar clamp, and the drive source is used to drive the third clamping travel screw to rotate so that the associated third half-bar clamp and the half-bar it clamps move along the third clamping travel guide.

[0341] When the chamfering device is used to chamfer the edge of the half rod in the chamfering area, the third clamping and traveling mechanism drives the third half rod clamp and the half rod it clamps to move along the first direction so as to achieve relative movement with the chamfering unit in the chamfering device so that the chamfering grinding wheel in the chamfering unit can chamfer the edge of the third half rod clamp and the half rod it clamps.

[0342] The aforementioned third half-bar clamping device and chamfering device may still have other variations.

[0343] In some embodiments, the half-bar grinding apparatus of this application includes a half-bar support device.

[0344] In some embodiments, the half-rod support device supports the half-rod so that the half-rod is placed horizontally and its length direction is aligned with a first direction. In some embodiments, the half-rod support device supports the half-rod so that the half-rod is placed horizontally and its length direction is aligned with a second direction.

[0345] In the following description, an example is given of a half-bar horizontally placed at a chamfered area with its length direction aligned with a first direction. The half-bar support device may include a half-bar support platform, which is disposed along the first direction on the grinding machine base and located at the chamfered area, for supporting at least one horizontally placed half-bar. If one half-bar is horizontally placed on the half-bar support platform, the length of the support platform is related to the length of the half-bar, and the width of the support platform may be related to the width of the half-bar. If two half-bars are horizontally placed side-by-side on the support platform, the length of the support platform matches the length of the half-bar, and the width of the support platform matches the sum of the widths of the two half-bars.

[0346] In some embodiments, the half-bar support device supports the half-bar in such a way that the half-bar is placed in contact with the slope support platform on one side (which may be referred to as the support bottom surface), so that the half-bar is placed horizontally and at least the top surface opposite the support bottom surface and the two edges adjacent to the top surface are exposed.

[0347] To ensure the half-bar is stably placed on the half-bar support platform, the half-bar support device may also include a half-bar positioning mechanism for positioning the half-bar supported by the platform. Thus, when the grinding device performs grinding operations on the half-bar supported by the platform, the positioning mechanism can fix the half-bar, preventing relative displacement between the half-bar and the platform during grinding, which would affect the grinding quality. The half-bar positioning mechanism can be, for example, an edge clamping mechanism located at the front and rear ends of the platform along its length to clamp the two ends of the half-bar; or, the edge clamping mechanism can be located on the left and right sides of the platform along its relative length to clamp the two sides of the half-bar.

[0348] Since the aforementioned half-bar support device can support the half-bar and expose the top surface opposite the support bottom surface and two edges adjacent to the top surface, the chamfering device may include a chamfering frame and at least one pair of chamfering units movably disposed on the chamfering frame, the at least one pair of chamfering units corresponding to the exposed pair of edges. Each chamfering unit has at least one chamfering die.

[0349] For a given chamfering unit, the chamfering unit includes a chamfering support movably mounted on the chamfering frame and at least one chamfering tool mounted on the chamfering support. In some embodiments, the chamfering surface of the chamfering tool faces downward at an angle, then the chamfering unit includes a chamfering support movably mounted vertically on the chamfering frame and at least one chamfering tool mounted on the chamfering support, wherein the at least one chamfering tool is used to chamfer the edge of the half-bar supported by the half-bar support device.

[0350] A chamfering support can be mounted vertically (i.e., in the third direction) on a chamfering frame via a chamfering support lifting mechanism. Using this lifting mechanism, the chamfering support can move vertically relative to the chamfering frame. In some embodiments, the chamfering support lifting mechanism may include a chamfering lifting guide rail and a chamfering lifting drive unit, wherein the chamfering lifting guide rail is vertically mounted on the chamfering frame, and the chamfering lifting drive unit drives the chamfering support and at least one chamfering die mounted thereon to move vertically along the chamfering lifting guide rail. In some embodiments, the chamfering lifting drive unit may include a chamfering lifting screw and a drive source, wherein the chamfering lifting screw is vertically mounted and associated with the chamfering support, and the drive source drives the chamfering lifting screw to rotate, causing the associated chamfering support and at least one chamfering die mounted thereon to move vertically along the chamfering lifting guide rail. In some examples, the drive source may be, for example, a drive motor. In some embodiments, the chamfering support lifting mechanism may include a chamfering lifting rack, a drive gear, and a drive source. The chamfering lifting rack is vertically mounted on the chamfering frame and parallel to the chamfering lifting guide rail. The drive gear is mounted on the chamfering support (e.g., at the bottom of the chamfering support) and meshes with the chamfering lifting rack. The drive source is associated with a drive wheel and is used to drive the drive wheel to rotate, causing the associated chamfering support and at least one chamfering die mounted on it to move vertically along the chamfering lifting guide rail. In some examples, the drive source may be, for example, a drive motor.

[0351] Furthermore, the chamfer supports in at least one pair of chamfering units can also be shared. For example, the first chamfer support in the first chamfering unit and the second chamfer support in the second chamfering unit of a pair of chamfering units can share the same chamfer support, and the shared chamfer support drives the pair of chamfers to move vertically in the chamfering frame through the chamfer support lifting mechanism.

[0352] Taking a pair of chamfering units as an example, the pair of chamfering units can be set at an angle. For example, in one example, the chamfering tool in the first chamfering unit is at a 45° angle to the horizontal or vertical line, and the chamfering tool in the second chamfering unit is at a 45° angle to the horizontal or vertical line. Of course, the above-mentioned angle is not limited to this. In different embodiments, other angles can be selected. For example, the tilt angle can be any angle from 40° to 60°, and is not limited to integer degrees.

[0353] The chamfering tool includes at least one grinding wheel. In some embodiments, the grinding wheel is a coarse grinding wheel or a fine grinding wheel. In some embodiments, the chamfering tool includes nested coarse grinding wheels and fine grinding wheels, for example, the coarse grinding wheel is nested within the fine grinding wheel, or the fine grinding wheel is nested within the coarse grinding wheel.

[0354] In this application, when chamfering the edges of a half-bar, at least one pair of chamfering units in the chamfering device chamfers the two edges of the half-bar supported by the half-bar support by driving relative movement of the chamfering device and the half-bar support device in a first direction. Therefore, in some embodiments, the chamfering device is a movable chamfering device and the half-bar support device is a fixed half-bar support device. In some embodiments, the chamfering device is a fixed chamfering device and the half-bar support device is a movable half-bar support device. The chamfering device is a movable chamfering device and the half-bar support device is a movable half-bar support device.

[0355] Taking a mobile chamfering device as an example, the chamfering device includes a chamfering frame traveling mechanism, which drives the chamfering frame and at least one pair of chamfering units thereon to move along a first direction.

[0356] In some embodiments, the chamfering frame traveling mechanism includes a chamfering traveling guide rail and a chamfering traveling drive unit, wherein the chamfering traveling guide rail is disposed on the grinding machine base along a first direction, and the chamfering traveling drive unit is used to drive the chamfering frame and at least one pair of chamfering units disposed thereon to move along the chamfering traveling guide rail.

[0357] In some embodiments, the chamfering travel drive unit includes a chamfering travel rack, a drive gear, and a drive source. The chamfering travel rack is disposed on the grinding machine base along a first direction and parallel to the chamfering travel guide rail. The drive gear is disposed on the chamfering frame (e.g., at the bottom of the chamfering frame) and meshes with the chamfering travel rack. The drive gear is driven to rotate by the drive source, and its teeth mesh with the chamfering travel rack, moving in accordance with the chamfering travel rack. The chamfering frame connected to the drive gear and at least one pair of chamfering units thereon move along the chamfering travel guide rail. The drive source is, for example, a drive motor.

[0358] In some embodiments, the chamfering travel drive unit includes a chamfering travel screw and a drive source, wherein the chamfering travel screw is disposed along a first direction and associated with a chamfering frame, and the drive source is used to drive the chamfering travel screw to rotate so that the associated chamfering frame and at least one pair of chamfering units thereon move along a chamfering travel guide. The drive source is, for example, a drive motor.

[0359] When using a chamfering device to chamfer the edges of a half-bar in a chamfering area, the chamfering frame and at least one pair of chamfering units are driven by the chamfering frame traveling mechanism to move in a first direction to achieve relative movement with the half-bar supported by the half-bar support device in the chamfering area, so that the chamfering abrasive in the at least one pair of chamfering units can chamfer the two edges of the half-bar supported by the half-bar support device in the chamfering area.

[0360] Taking a mobile half-bar support device as an example, the half-bar support device includes a support and travel mechanism, which drives the half-bar support device and the half-bar it supports to move along a first direction.

[0361] In some embodiments, the supporting travel mechanism includes a supporting travel guide rail and a supporting travel drive unit, wherein the supporting travel guide rail is disposed on the half-bar supporting device along a first direction, and the supporting travel drive unit is used to drive the half-bar supporting device and the half-bar it supports to move along the supporting travel guide rail.

[0362] In some embodiments, the supporting travel drive unit includes a supporting travel rack, a drive gear, and a drive source. The supporting travel rack is disposed on the half-bar supporting device along a first direction and parallel to the supporting travel guide rail. The drive gear is disposed on the half-bar supporting device and meshes with the supporting travel guide rail. The drive gear is driven to rotate by the drive source, and its teeth mesh with the supporting travel guide rail, causing it to travel in accordance with the supporting travel guide rail. The half-bar supporting device connected to the drive gear and the half-bar it supports move along the supporting travel guide rail. The drive source is, for example, a drive motor.

[0363] In some embodiments, the supporting travel drive unit includes a supporting travel screw and a drive source, wherein the supporting travel screw is arranged along a first direction and associated with a half-bar supporting device, and the drive source is used to drive the supporting travel screw to rotate so that the associated half-bar supporting device and the half-bar it supports move along a supporting travel guide. The drive source is, for example, a drive motor.

[0364] When using a chamfering device to chamfer the edges of a half-bar in a chamfering area, the half-bar support device and the half-bar it supports are driven by a supporting travel mechanism to move in a first direction to achieve relative movement with at least one pair of chamfering units in the chamfering device so that the chamfering abrasive in at least one pair of chamfering units can chamfer the two edges of the half-bar support device and the half-bar it supports.

[0365] The half-bar grinding equipment of this application may also include a cleaning device. The cleaning device may be installed on the grinding machine base and is used to clean the half-bar.

[0366] The half-bar grinding equipment of this application may further include a feeding and conveying device, located at the loading area, for conveying the half-bar to be ground. In some embodiments, the feeding and conveying device may be, for example, a conveyor belt device, including a conveyor belt wound around two conveyor rollers arranged opposite each other, at least one of the two conveyor rollers being shaft-connected to a feeding drive source, which may be, for example, a servo motor.

[0367] The half-bar grinding equipment of this application may further include a feeding conveyor device located at the unloading area for conveying the ground half-bar. In some embodiments, the feeding conveyor device may be, for example, a conveyor belt device, including a conveyor belt wound around two conveyor rollers arranged opposite each other, at least one of the two conveyor rollers being shaft-connected to a feeding drive source, which may be, for example, a servo motor.

[0368] In some embodiments, the feeding conveyor and the unloading conveyor share a common structure.

[0369] The half-bar grinding equipment of this application may also include a half-bar transfer device for transferring the half-bar between various functional areas.

[0370] In some embodiments, the half-bar transfer device includes: a transfer mounting frame, a transfer clamp, a transfer lifting mechanism, and a transfer translation mechanism.

[0371] A transfer mounting frame is mounted on the grinding machine base. In some embodiments, the functional areas are arranged in parallel along a second direction, and the transfer mounting frame spans across the grinding machine base in the second direction. The transfer mounting frame may correspond to the entire width of the grinding machine base to cover the functional areas within the width of the grinding machine base. In some embodiments, the functional areas are arranged sequentially along a first direction, and the transfer mounting frame spans across the grinding machine base in the first direction. The transfer mounting frame may correspond to the entire depth of the grinding machine base to cover the functional areas within the depth of the grinding machine base. It should be noted that the following description of the half-bar transfer device is based on the example of the functional areas being arranged in parallel along the second direction.

[0372] The transfer clamp is used to hold the half-bar. In some embodiments, the transfer clamp may further include: a clamping base, at least a pair of clamping arms disposed on opposite sides of the clamping base along a first direction, and a clamping arm drive mechanism.

[0373] At least one pair of clamping arms are arranged opposite each other on the clamping seat along the first direction by a clamping arm driving mechanism, for clamping two end faces of the half rod along the length direction, so that the clamped half rod is in a horizontal state.

[0374] A clamping arm drive mechanism is used to drive at least one clamping arm in at least one pair of clamping arms to move along a horizontal line to adjust the clamping distance between the pair of clamping arms. In some embodiments, two clamping arms in a pair are arranged opposite each other along a first direction, and the clamping arm drive mechanism can drive at least one clamping arm in the pair to move along the first direction. For example, the clamping arm drive mechanism can drive one clamping arm in the pair to move towards or away from the other clamping arm along the first direction, or drive two clamping arms in the pair to move towards or away from each other along the first direction to adjust the clamping distance between the oppositely arranged pair of clamping arms.

[0375] In some embodiments, the clamping arm driving mechanism may include an opening / closing guide rod and an opening / closing driving unit. The opening / closing guide rod is disposed on the clamping seat along a first direction for arranging a pair of clamping arms. The opening / closing driving unit is used to drive at least one of the clamping arms in the pair to move along the opening / closing guide rod disposed along the first direction. For example, it drives one of the clamping arms in the pair to move towards or away from the other clamping arm along the opening / closing guide rod, or it drives two of the clamping arms in the pair to move towards or away from each other along the opening / closing guide rod. To ensure the stability of the clamping arms moving horizontally along the first direction, the number of opening / closing guide rods may be multiple, for example, two. Of course, the number of opening / closing guide rods may also be other, for example, three, five, six, or more. Taking three as an example, the three opening / closing guide rods may be arranged in an isosceles triangle or an equilateral triangle, for example.

[0376] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder. One end of the horizontal telescopic rod is associated with a clamping arm, and the other end is associated with the telescopic cylinder, which is mounted on a clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend or retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, driving the associated clamping arm to move along an opening and closing guide rod arranged in a first direction, reducing the clamping distance between the two clamping arms to clamp the half-rod located between the two clamping arms. Alternatively, two telescopic cylinders associated with the two clamping arms can each drive their respective horizontal telescopic rods to retract inward, driving the associated clamping arms to move towards each other along an opening and closing guide rod arranged in the first direction, reducing the clamping distance between the two clamping arms to clamp the half-rod located between the two clamping arms. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, driving the associated clamping arm to move along an opening and closing guide rod arranged in the first direction, increasing the clamping distance between the two clamping arms to release the clamped half-rod. Alternatively, the two telescopic cylinders associated with the two clamping arms can drive their respective horizontal telescopic rods to extend outward, thereby driving the associated clamping arms to move in opposite directions along the opening and closing guide rods set in the first direction, increasing the clamping distance between the two clamping arms to release the clamped half rod.

[0377] In some embodiments, the opening / closing drive unit includes a lead screw and an opening / closing motor. One end of the lead screw (e.g., the threaded end) is associated with a clamping arm, and the other end is associated with the opening / closing motor, which is mounted on a clamping seat. In practical applications, the opening / closing motor can drive the lead screw to rotate. For example, the opening / closing motor drives the lead screw to rotate forward (or backward), causing one of the clamping arms in a pair to move towards the other clamping arm along an opening / closing guide rod arranged in a first direction, or causing both clamping arms in a pair to move towards each other along the opening / closing guide rod arranged in the first direction, thereby reducing the clamping distance between the two clamping arms to clamp the half-bar located between the two clamping arms. Correspondingly, the opening / closing motor drives the lead screw to rotate in the reverse direction (or forward), causing one of the clamping arms in a pair to move away from the other clamping arm along an opening / closing guide rod arranged in the first direction, or causing both clamping arms in a pair to move away from each other along the opening / closing guide rod arranged in the first direction, thereby increasing the clamping distance between the two clamping arms to release the clamped half-bar.

[0378] In some embodiments, the opening and closing drive unit includes a bidirectional lead screw and an opening and closing motor. The bidirectional lead screw is arranged along a first direction and is a left-hand and right-hand lead screw. It has two sections of threads on its body with opposite directions of rotation, i.e., one section of thread is a left-hand thread and the other section of thread is a right-hand thread. One section of thread can be associated with one clamping arm and the other section of thread can be associated with another clamping arm (e.g., the left-hand thread is associated with the first clamping arm and the right-hand thread is associated with the second clamping arm, or the right-hand thread is associated with the first clamping arm and the left-hand thread is associated with the second clamping arm). The opening and closing motor is associated with the bidirectional lead screw and is used to drive the bidirectional lead screw to rotate so that the associated first clamping arm and second clamping arm move toward each other or away from each other along the opening and closing guide rod arranged along the first direction. In practical applications, for example, by using an opening and closing motor to drive the bidirectional lead screw to rotate forward (or reverse), the two associated clamping arms are driven to move towards each other along the opening and closing guide rod set in the first direction, reducing the clamping distance between the two clamping arms to clamp the half-bar located between the two clamping arms; or, by using an opening and closing motor to drive the bidirectional lead screw to rotate in the reverse direction (or forward), the two associated clamping arms are driven to move away from each other along the opening and closing guide rod set in the first direction (i.e., moving away from each other), increasing the clamping distance between the two clamping arms to release the clamped half-bar. The opening and closing motor can be located in the middle section or at one end of the bidirectional lead screw.

[0379] In some embodiments, the clamping portion of the clamping arm is designed to rotate. The transfer fixture includes a clamping portion rotation mechanism for driving the clamping portion on the clamping arm to rotate. In some implementations, driven by the clamping portion rotation mechanism, the clamping portion of the clamping arm rotates about a clamping centerline (e.g., the line connecting the centers of the clamping portions of the two clamping arms is used as the clamping centerline), and the clamped half-bar rotates accordingly about the clamping centerline. In actual machining operations, by driving the half-bar to rotate along the clamping centerline through the clamping portion rotation mechanism, the positional relationship of the clamped half-bar relative to the grinding device (e.g., including a grinding device or a chamfering device) can be adjusted.

[0380] In some embodiments, the clamping part is a multi-point contact clamping head. Understandably, the contact method between the multi-point contact clamping head and the end face of the half-bar is not limited to point contact. For example, the clamping part may have multiple protrusions to contact the end face of the half-bar, wherein each protrusion can have surface contact with the end face of the half-bar. In one implementation, the protrusions of the clamping part can also be connected to the clamping part body via a spring along a horizontal line, thereby forming multi-point floating contact, allowing the transfer fixture to adapt to the flatness of the end face of the half-bar when clamping it to secure the half-bar.

[0381] In some embodiments, the portion of a pair of clamping parts of the transfer fixture that contacts the half-bar is configured as a rigid structure to prevent the clamped half-bar from being disturbed during grinding operations (e.g., including grinding operations, chamfering operations) and affecting the machining accuracy.

[0382] In practical applications, the clamping part rotation mechanism may include two rotatable structures disposed on two clamping parts in a pair of clamping arms, and a drive source for driving at least one of the two rotatable structures to rotate.

[0383] In some embodiments of this application, the clamping portion of the clamping arm can be configured as a rotatable frustum, the circular plane of which contacts the end face of the half-bar and remains relatively stationary after being pressed against the end face of the half-bar. The clamping portion also includes a locking structure, so that the clamping portion of the clamping arm is in a locked state when grinding a selected surface. During the switching between different grinding surfaces, the clamping portion rotates around the center of the frustum under the drive of the clamping portion rotation mechanism.

[0384] In some implementations, the clamping part of the gripper arm includes a rotatable frustum and a series of protruding contacts disposed on the frustum. Each contact has a contact plane for contacting the clamped half-bar. The frustum rotates under the drive of the clamping part's rotating mechanism. Regarding the contacts, in some implementations, the protrusion length of the contacts, i.e., their position on the horizontal line, is adjustable. This allows for adjustment of the protrusion length of the contacts during the clamping of the half-bar, especially for half-bars with low end-face flatness, ensuring that the contact surface of each contact is in close contact with the end face of the half-bar. The protrusion length is the length of the horizontal line from the circular plane of the frustum to the contact plane of the contact.

[0385] The clamping part rotation mechanism can be disposed on one of the clamping arms of a pair of clamping arms to drive the clamping parts of the pair of clamping arms and the clamped half rod to rotate; or the clamping part rotation mechanism can be disposed on both clamping arms of a pair of clamping arms and coordinately control the two clamping parts of the pair of clamping arms to rotate at the same angle and in the same direction. In some implementations, the drive source in the clamping part rotation mechanism can be, for example, a drive motor.

[0386] Thus, in this embodiment of the application, the transfer clamp configured in the half-bar transfer device can horizontally clamp the half-bar and drive the clamped half-bar to rotate at a predetermined angle around the clamping center line.

[0387] The transfer lifting mechanism is used to drive the transfer fixture to move vertically up and down on the transfer mounting frame. In some embodiments, the transfer lifting mechanism may include: a vertical lifting guide rail and a vertical lifting drive unit.

[0388] The vertical lifting guide rail can be mounted on the transfer mounting frame in the vertical direction (i.e., the third direction). For example, a mounting structure (e.g., a mounting plate) is provided on the transfer mounting frame, and the vertical lifting guide rail can be mounted on the mounting structure in the vertical direction (i.e., the third direction). Alternatively, the vertical lifting guide rail can be mounted on the transfer fixture in the vertical direction (i.e., the third direction). For example, a mounting structure (e.g., a mounting plate) is provided on the transfer fixture, and the vertical lifting guide rail can be mounted on the mounting structure in the vertical direction (i.e., the third direction). To ensure the stability of the transfer fixture's lifting movement along the vertical lifting guide rail, the number of vertical lifting guide rails can be multiple; for example, two vertical lifting guide rails may be included.

[0389] In some embodiments, the vertical lifting drive unit includes a vertical lead screw and a lifting motor. One end of the vertical lead screw is associated with the clamp of the transfer fixture or the mounting structure of the transfer fixture, and the other end is associated with the lifting motor, which is mounted on the transfer mounting frame or the mounting structure of the transfer mounting frame. In practical applications, the lifting motor can drive the vertical lead screw to rotate in both directions. For example, the lifting motor drives the vertical lead screw to rotate in the forward direction (or in the reverse direction), driving the transfer fixture to rise along the vertical lifting guide rail provided in the vertical direction. Correspondingly, the lifting motor can drive the vertical lead screw to rotate in the reverse direction (or in the forward direction), driving the transfer fixture to descend along the vertical lifting guide rail provided in the vertical direction.

[0390] In some embodiments, the transfer lifting mechanism may include: a vertical lifting guide rod and a vertical lifting drive unit.

[0391] The vertical lifting guide rod can be mounted on the transfer mounting frame in a vertical direction (i.e., a third direction). For example, the transfer mounting frame has a mounting structure (e.g., a mounting plate), and the vertical lifting guide rod can be mounted on the mounting structure in a vertical direction (i.e., a third direction). To ensure the stability of the transfer fixture's vertical movement along the vertical lifting guide rod, there can be multiple vertical lifting guide rods; for example, there can be two vertical lifting guide rods.

[0392] In some embodiments, the vertical lifting drive unit includes a vertical telescopic rod and a telescopic cylinder. One end of the vertical telescopic rod is associated with a clamp, and the other end is associated with the telescopic cylinder, which is mounted on a transfer mounting frame or structure. In practical applications, the telescopic cylinder can drive the vertical telescopic rod to extend or retract. For example, the telescopic cylinder can drive the vertical telescopic rod to retract inward, driving the transfer clamp to rise along the vertical lifting guide rod. Correspondingly, the telescopic cylinder can drive the vertical telescopic rod to extend outward, driving the transfer clamp to descend along the vertical lifting guide rod.

[0393] In some embodiments, the vertical lifting drive unit includes a vertical lead screw and a lifting motor. One end of the vertical lead screw is associated with a clamp, and the other end is associated with the lifting motor, which is mounted on a transfer mounting frame or structure. In practical applications, the lifting motor can drive the vertical lead screw to rotate in both directions. For example, the lifting motor drives the vertical lead screw to rotate in the forward direction (or in the reverse direction), driving the transfer clamp to rise along the vertical lifting guide rod. Correspondingly, the lifting motor can drive the vertical lead screw to rotate in the reverse direction (or in the forward direction), driving the transfer clamp to descend along the vertical lifting guide rod.

[0394] The transfer and translation mechanism is used to drive the transfer fixture to translate along the transfer mounting frame. The transfer and translation mechanism is also used to drive the transfer fixture to move along the transfer mounting frame in a second direction. The transfer and translation mechanism includes a transfer and translation guide rail and a translation drive unit. The transfer and translation guide rail is disposed on the transfer mounting frame along the second direction, and the translation drive unit is used to drive the transfer fixture to move along the transfer and translation guide rail disposed in the second direction.

[0395] In some embodiments, the translation drive unit includes a transfer translation rack, a drive gear, and a drive source. The transfer translation rack is disposed on a transfer mounting frame along a second direction and parallel to the transfer translation guide rail. The drive gear is disposed on the mounting structure and meshes with the transfer translation rack. The drive gear is driven to rotate by the drive source, and its teeth mesh with the transfer translation rack, moving in accordance with the transfer translation rack. The mounting frame connected to the drive gear and its provided transfer clamp move along the transfer translation guide rail. The drive source is, for example, a drive motor.

[0396] In some embodiments, the cutting travel drive unit includes a transfer translation screw and a drive source, wherein the transfer translation screw is arranged along a second direction and associated with a mounting structure, and the drive source is used to drive the transfer translation screw to rotate so that the associated mounting structure and its provided transfer fixture move along the transfer translation guide rail. The drive source is, for example, a drive motor.

[0397] Using the half-bar transfer device in this application, both ends of the half-bar can be clamped, and the half-bar can be driven to rotate, lift, and translate.

[0398] As previously mentioned, in some embodiments, the functional areas may be arranged along a first direction or a second direction. Taking parallel arrangement along the second direction as an example, when the half-bar grinding equipment includes a loading area, a grinding area, a chamfering area, and an unloading area, the loading area, grinding area, chamfering area, and unloading area are arranged in parallel along the second direction (e.g., in the manner of loading area, grinding area, chamfering area, and unloading area, or in the manner of grinding area, loading area, unloading area, and chamfering area, etc.). However, the placement method of the half-bar in each functional area can still vary. For example, in some embodiments, the half-bars in each functional area are all placed horizontally along the first direction, that is, the half-bars are placed horizontally and the length direction of the horizontally placed half-bars is consistent with the first direction. In some embodiments, although the half-bars in each functional area are placed horizontally, their placement directions are not completely consistent. For example, the half-bars in the grinding area are placed horizontally along the first direction, while the half-bars in the chamfering area are placed horizontally along the second direction.

[0399] In embodiments where the half-bars are placed in different orientations in various functional areas, the half-bar transfer device may further include a vertical rotation mechanism for driving the transfer fixture to rotate vertically, thereby causing the half-bars held by the transfer fixture to change their placement orientation.

[0400] In some embodiments, the vertical rotation mechanism may include a shaft and a rotary motor, one end of which is associated with a transfer fixture (e.g., a clamp of the transfer fixture), and the other end of which is associated with the rotary motor. In practical applications, the rotary motor can drive the shaft to rotate. For example, the rotary motor drives the shaft to rotate forward (or backward), driving the transfer fixture to rotate forward (or backward) to rotate the half-bar located between the two clamping arms forward (or backward), changing its placement orientation. Correspondingly, the rotary motor drives the shaft to rotate backward (or forward), driving the transfer fixture to rotate backward (or forward) to rotate the half-bar located between the two clamping arms backward (or forward), changing its placement orientation. Assuming there are multiple placement directions for the half-bar, such as a placement direction along a first direction and a placement direction along a second direction, the rotary motor driving the shaft in the vertical transfer mechanism rotates forward or backward (e.g., the turning angle can be 90°) to drive the transfer fixture to rotate vertically to switch between the first and second directions. However, this is not a limitation. For example, multiple placement directions for the half-bar can be set, and the rotary motor driving the shaft in the vertical transfer mechanism rotates forward or backward. The angle difference between the initial placement direction and the target placement direction is used to drive the transfer fixture to rotate vertically to switch between the first and second directions. Generally, in the vertical rotation mechanism of the half-bar transfer device, the rotary motor driving the shaft in the vertical transfer mechanism can be limited to rotation in only one direction (e.g., forward or backward rotation) and the rotation angle range can be limited to within 90° (inclusive).

[0401] In some embodiments, the half-bar transfer device includes a half-bar centering mechanism disposed on a clamp, used to ensure that the centerline of the horizontally placed half-bar is aligned with the centerline of the half-bar clamp in the width direction. In some embodiments, the half-bar centering mechanism may include at least one pair of clamping members and a clamping member driving mechanism. The at least one pair of clamping members are arranged opposite each other along a second direction and are movable. In this case, when the clamping member driving mechanism drives the at least one pair of clamping members to move in opposite directions, it can clamp the half-bar between them and ensure that the centerline of the half-bar is located in the exact center of the half-bar clamp, thereby achieving centering of the half-bar.

[0402] The following describes the execution process of the half-bar grinding equipment in the aforementioned embodiments:

[0403] First, the half-bar to be ground is transferred and placed in the grinding area using the feeding conveyor and half-bar transfer device so that the end of the half-bar along the length direction is held by the first half-bar clamping device.

[0404] A grinding device is used to grind the four sides of a half-bar at a grinding location. Specifically, through the relative movement of the grinding device and the first half-bar clamping device, at least one grinding wheel in the grinding device grinds at least one exposed side of the half-bar held by the first half-bar clamping device. After grinding at least one side is completed, the half-bar can be rotated using the first half-bar clamping device to change its position and expose other unground sides. The grinding process continues with at least one grinding wheel in the grinding device grinding the new sides until all four sides are ground.

[0405] Alternatively, a half-bar that has completed grinding is transferred using a half...
