Description

Technical Field

[0001] The present application relates to the technical field of silicon material processing, and in particular to a device for cutting and square-cutting a silicon material. Background Art

[0002] When manufacturing various semiconductor and photovoltaic devices, it is necessary to cut semiconductor workpieces containing hard and brittle materials such as silicon, sapphire, or ceramics into wafers of required thickness. Taking silicon rod cutting as an example, generally, the general operation process includes: first using a cutter to cut the original long silicon rod to form multiple short silicon rods, and then using a squarer to square the cut short silicon rods to form a single crystal silicon cube, and then using a slicer to slice the silicon cube finished product to obtain silicon wafers.

[0003] Generally, for the cutting and squaring operations of silicon rods, the material for manufacturing silicon wafers, each process is arranged independently, and the operating equipment is scattered in different production units or production workshops or different production areas of production workshops. The conversion of workpieces for different process operations requires transportation and deployment. In this way, the process is complicated and inefficient, requiring more manpower or transfer equipment, and there are great safety hazards. In addition, there are many flow links between the operating equipment of each process, which increases the risk of damage to the workpiece during the transfer of the workpiece, and is prone to non-conformity caused by non-production factors, reducing the qualified rate of the product and causing unreasonable losses. Therefore, how to integrate the cutting and squaring operations of the workpiece into the same equipment to improve processing efficiency and product qualified rate is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] In view of the shortcomings of the related technologies mentioned above, the purpose of the present application is to provide an integrated cutting and squaring device to solve the problems of low independent processing efficiency and low product qualification rate of workpiece cutting and squaring operations.

[0005] To achieve the above-mentioned purpose and other related purposes, the present application provides an integrated cutting and squaring device, comprising: a machine base, comprising a cutting station extending longitudinally from the proximal end to the distal end, and a squaring station arranged on the distal side of the cutting station; the extension line of the axis line of the workpiece placed longitudinally on the cutting station is perpendicular to the axis line of the workpiece placed vertically on the squaring station; a cutting table, comprising a guide rail arranged on the cutting station and a carrier arranged on the guide rail for carrying the longitudinally placed workpiece; a squaring table, comprising a carrying table rotatably arranged on the squaring station for carrying the vertically placed workpiece; a cutting device, arranged on the base, comprising a frame movable longitudinally, a plurality of guide wheels arranged on the frame, and a cutting loop surrounding the plurality of guide wheels, the wire saw formed by the cutting loop being used to move longitudinally with the frame to sequentially perform cutting operations on the workpieces placed longitudinally on the cutting station, and to sequentially perform squaring operations on the workpieces placed vertically on the squaring station.

[0006] To sum up, the integrated cutting and squaring equipment provided by the present application integrates the workpiece cutting operation and the squaring operation on the same equipment, thereby reducing the number of times the workpiece is manually moved, thereby reducing the risk of workpiece damage, improving the product qualification rate, and improving the workpiece processing efficiency; in particular, the integrated cutting and squaring equipment of the present application sets the cutting station center and the squaring station center on the same axis, which not only simplifies the equipment footprint, but also allows two different cutting processes to share the same cutting frame without the need for additional adjustment of the cutting frame, thereby saving the space occupied by the operating equipment while also improving the cutting operation efficiency; furthermore, the present application utilizes the same cutting device loop to perform both cutting and squaring operations on the workpiece, thereby reducing the repeated winding of the cutting line, thereby simplifying the equipment structure and saving production costs.

[0020] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0021] In the following description, with reference to the accompanying drawings, several embodiments of the present application are described. It should be understood that other embodiments may also be used, and mechanical composition, structure, electrical and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used here are only to describe specific embodiments and are not intended to limit the present application. Spatially related terms, such as "upper", "lower", "left", "right", "below", "below", "lower", "above", "upper", etc., may be used in the text to facilitate the description of the relationship between an element or feature shown in the figure and another element or feature.

[0022] Although the terms first, second, etc. are used to describe various elements in this article in some instances, these elements should not be limited by these terms. These terms are only used to distinguish an element from another element. For example, the first carrier can be referred to as the second carrier, and similarly, the second carrier can be referred to as the first carrier, without departing from the scope of the various described embodiments. The first carrier, the second carrier are all describing a certain carrier, but unless the context clearly indicates otherwise, they are not the same carrier. Similar situations also include the first piece transport device and the second piece transport device.

[0023] As described in the background technology, when the workpiece is cut and squared, each process is arranged independently and the operation equipment is dispersed. The conversion of the workpieces for different process operations requires handling and deployment, so the processing efficiency is low and the workpiece is easily damaged, thereby reducing the qualified rate of the product. In view of this, the present application discloses a cutting and squaring integrated equipment, which integrates the workpiece cutting operation and the square opening operation on the same equipment, reduces the number of manual handling of the workpiece, thereby reducing the risk of workpiece damage, improving the qualified rate of the product, and improving the workpiece processing efficiency; in particular, the cutting and squaring integrated equipment of the present application sets the cutting station center and the square opening station center on the same axis, which not only simplifies the equipment space, but also allows two different cutting processes to share the same cutting frame without the need for additional adjustment of the cutting frame, thereby saving the space occupied by the operation equipment and improving the cutting operation efficiency; furthermore, the present application uses the same cutting device loop to cut and square the workpiece, reducing the repeated winding of the cutting line, thereby simplifying the equipment structure and saving production costs.

[0024] In order to clarify the definition of direction and the operation mode between different structures, a three-dimensional space defined by a horizontal direction (also called a first direction or X direction), a vertical direction (also called a second direction or Y direction), and a vertical direction (also called a third direction or Z direction) is defined in the embodiments disclosed in this application. The horizontal direction, the vertical direction, and the vertical direction are all straight lines and are perpendicular to each other. For example, the width extension direction of each station is also called the lateral direction and is defined as the horizontal direction (for example Figure 1 The X direction in the figure), the length extension direction of each station is defined as the longitudinal direction (for example Figure 1 The vertical direction is also called the lifting direction, the vertical line direction or the up-down direction, and is defined as the vertical direction (e.g. Figure 1 The Z direction in the figure).

[0025] In order to clearly illustrate the positional relationship between the various devices, components, structures or mechanisms in the embodiments of the present application, the side of the cut-off and square-cutting integrated device that is connected to the feeding and conveying device is defined as the proximal end or the near side, and the side of the cut-off and square-cutting integrated device where the workpiece is located when performing the square cutting operation at the square cutting station is defined as the distal end or the far side. It should be understood that when the workpiece moves from one side of the cut-off and square-cutting integrated device to the other side opposite to perform the cut-off operation and the grinding operation respectively, the proximal end or the near side and the far end or the far side correspond to the opposite sides of the cut-off and square-cutting integrated device, and the two are opposite and far away from each other.

[0026] The integrated cutting and squaring equipment of the present application can be used to cut and square semiconductor workpieces containing hard and brittle materials such as polycrystalline silicon or single crystal silicon ingots or silicon rods, sapphire, glass or ceramics, so that they can be cut into compliant structures (or remove non-compliant parts). For example, taking the cutting of single crystal silicon rods as an example, the general operation process includes: first cutting the original long silicon rod to form multiple short silicon rods, and after the cutting is completed, squaring the cut short silicon rods to form a compliant single crystal silicon cube. In the following embodiments, we choose the cutting operation of silicon-containing crystalline silicon workpieces to illustrate. The crystalline silicon workpiece can be either a single crystal silicon rod or a polycrystalline silicon rod, which should all fall within the scope of the claims of the present application.

[0027] In any embodiment provided in the present application, the single crystal silicon rod is a rod-shaped single crystal silicon grown from a melt by a Czochralski method or a floating zone melting method, such as a single crystal silicon rod of about 5000 mm (e.g., a specification of 5360 mm, etc.) in length or a single crystal silicon rod of about 800 mm in length, etc., which is common in silicon rod processing. The polycrystalline silicon rod is a silicon rod in which silicon is precipitated on the surface of a silicon core wire by a precipitation technique such as a chemical vapor deposition technique, but is not limited thereto.

[0028] See also Figure 1 to Figure 2 ,in, Figure 1 The diagram shows a schematic diagram of the structure of a cut-off integrated device in one embodiment of the present application. Figure 2 The figure shows a schematic diagram of the cut-off and square-off integrated device of the present application in a workpiece feeding embodiment. Figure 1 to Figure 2 As shown, the integrated cutting and squaring equipment of the present application comprises: a machine base 1, a cutting table 2, a squaring table 3, and a cutting device 4.

[0029] The following is a detailed description of the integrated device for cutting off the square of the present application.

[0030] The machine base 1 is the main component of the cut-off and squared-off integrated device, and is used to provide a workpiece processing platform and bear the working parts. In practical applications, the machine base is large in size and weight to provide a large mounting surface and a strong stability of the whole machine. It should be understood that the machine base 1 can be used as the base for different structures or components that perform processing operations in the cut-off and squared-off integrated device, and the specific structure of the machine base can be changed based on different functional requirements or structural requirements. In some examples, the machine base 1 includes a fixed structure or a limiting structure such as a base, a column, a frame, etc. for receiving different components in the cut-off and squared-off integrated device, which are all the machine bases described in this application. At the same time, in some examples, the machine base can be used as an integrated base, and in some examples, the machine base can include multiple independent bases.

[0031] The machine base has a workpiece processing platform, and the workpiece processing platform can be divided into a plurality of functional areas according to the specific work content of the workpiece processing operation. For example, in some embodiments, the workpiece processing platform includes a truncation area and a square opening area. In some embodiments, the workpiece processing platform includes a truncation area, a square opening area, and a loading area. In some embodiments, the workpiece processing platform includes a truncation area, a square opening area, a loading area, and a unloading area.

[0032] It should be noted that in each example provided in this application, the functional location is defined by the travel path and range of the processing device at the functional location. For example, the cutting device of the cutting and squaring integrated device is located at the cutting location, and the range of the cutting location is the range occupied by the cutting device in the process of completing the cutting operation; similarly, the squaring device of the cutting and squaring integrated device is located at the squaring location, and the range of the squaring location is the range occupied by the squaring device in the process of completing the squaring operation. The shape of the workpiece processing platform can be determined based on the machine base, or can be determined based on the processing needs of the machine base, the cutting device, and the squaring device.

[0033] exist Figure 1 to Figure 2 In the embodiment shown, a workpiece processing platform is provided on the machine base 1, and the workpiece processing platform is provided with functional areas such as a truncation area and a squaring area. A truncation device is provided at the truncation area for truncation of the workpiece located at the truncation area. A squaring device is provided at the squaring area for squaring the workpiece located at the squaring area. Specifically, the machine base 1 includes a truncation station 11 and a squaring station 12.

[0034] like Figure 1As shown, the cutting station 11 extends longitudinally from the proximal end to the distal end of the machine base 1, and the squaring station 12 is arranged on the distal side of the cutting station 11. The extension line of the axis of the workpiece A placed longitudinally on the cutting station 11 is perpendicular to the axis of the workpiece placed vertically on the squaring station 12 and intersects in a plane, that is, the extension line of the axis of the workpiece A located on the cutting station 11 and the axis of the workpiece located on the squaring station 12 are perpendicular to each other in the plane where Y and Z are located. It is not difficult to understand that when the extension line of the axis of the workpiece A and the axis of the workpiece located on the squaring station are perpendicular to each other in the plane where Y and Z are located, after the cutting device completes the cutting operation on the workpiece A, when performing the squaring operation on the workpiece located on the squaring station, it only needs to move longitudinally from the cutting station 11 to the squaring station 12 without generating a lateral displacement.

[0035] In the present application, since the center of the cutting station 11 of the integrated cutting and squaring equipment, that is, the long cylindrical workpiece is placed at the cutting station 11 after centering, the axis line of the cutting station 11 is orthogonal to the vertical axis line of the squaring station and is located on the same plane, when the cutting device 4 moves in the Y direction to switch the cutting process, there is no need to adjust the angle of the cutting device 4 in the X direction, and the cutting angle of the wire saw can be consistent with the expected angle required by the process. In this way, the two different cutting processes, cutting operation and squaring operation, share the same cutting frame without the need for additional adjustment of the cutting frame, thereby saving the space occupied by the operating equipment while also improving the cutting operation efficiency.

[0036] See also Figures 3 to 5 , and combined with Figure 1 to Figure 2 ,in, Figure 3 Show this application Figure 1 The schematic diagram of the structure of the carrier in the embodiment shown, Figure 4 Show this application Figure 3 The schematic diagram of the structure of the vehicle in the embodiment shown in FIG. 1 is shown in FIG. 1 from another perspective. Figure 5 The diagram shows the structure of the cutting station in the cutting and square-cutting integrated device of the present application at a certain viewing angle. Figure 1 to Figure 2 As shown, in order to realize the cutting operation of the workpiece, the cutting station 11 includes a cutting table 2, and the cutting table 2 is longitudinally arranged on the cutting station 11, including a guide rail and a carrier 21.

[0037] like Figure 1 to Figure 2As shown, the carrier 21 is arranged on the guide rail for carrying the workpiece A placed longitudinally. In some embodiments, the carrier 21 is configured in plurality, and the plurality of carriers are arranged at intervals in the longitudinal direction, so as to support the plurality of workpiece segments formed after the workpiece is cut. Generally, each workpiece segment can be supported by at least one carrier. In some embodiments, a workpiece segment can be supported by one carrier, and when the carrier supports the workpiece segment, it is located in the center area of ​​the workpiece segment, that is, the carrier supports the workpiece segment corresponding to the center area of ​​the workpiece segment. In some embodiments, a workpiece segment can be supported by two or more carriers, and the two or more carriers are arranged at intervals.

[0038] like Figure 3 to Figure 4 As shown, each carrier 21 includes a support frame 211, a support frame shifting mechanism 212, a workpiece transfer mechanism 213, and a support mechanism 214. The support frame 211 is the main structure of the carrier 21. In some embodiments, the support frame shifting mechanism 212 is located at the bottom of the support frame 211. The support frame shifting mechanism 212 can be used to drive the support frame 211 (i.e., the carrier 21) to move in the longitudinal direction. The workpiece transfer mechanism 213 is arranged at the top of the support frame 211 to drive the supported workpiece A to move in the longitudinal direction relative to the support frame 211. The movement of the workpiece A in the longitudinal direction can be achieved not only by driving the support frame shifting mechanism 212 to drive the support frame 211 (i.e., the carrier 21) to move (at this time, the carrier 21 supports the workpiece A), but also by directly driving the workpiece A through the workpiece transfer mechanism 213.

[0039] In some embodiments, the guide rail (not shown) is longitudinally arranged on the cutting table 2. In some embodiments, the cutting station 11 is provided with a shift groove arranged along the longitudinal direction, and the shift groove can run through the entire cutting station 11. The guide rail is longitudinally arranged on opposite sides of the shift groove, and the shift groove is also equipped with a rack arranged in parallel with the guide rail. Through the rack and the guide rail, the carrier 21 can be moved along the longitudinal direction in the entire cutting station.

[0040] In some embodiments, the support frame shifting mechanism includes a slider and a mobile driving unit, the slider is located at the bottom of the support frame and is mounted on the guide rail, the mobile driving unit may include a driving gear and a gear driving motor associated with the driving gear, the driving gear is meshed with the rack, and the gear driving motor drives the connected driving gear to rotate, and through the meshing of the driving gear and the rack, the carrier is driven to move on the guide rail in the longitudinal direction at the cutting station.

[0041] In actual applications, when the workpieces are placed horizontally on each carrier, the support frame shifting mechanism in each carrier drives the respective carrier to move in the longitudinal direction, thereby driving the workpieces supported by each carrier to move in the longitudinal direction.

[0042] Of course, the support frame shifting mechanism may still be modified in other ways. For example, in other embodiments, the support frame shifting mechanism includes a chain conveying mechanism or a conveyor belt mechanism.

[0043] The workpiece transfer mechanism is used to drive the workpiece to move along the longitudinal direction. In some embodiments, the workpiece transfer mechanism includes a roller group and a roller group driving unit.

[0044] like Figure 3 to Figure 4 As shown, the workpiece transfer mechanism 213 includes two rows of roller groups arranged in parallel on the carrier 21 along the transverse direction, which are used to drive the workpiece A to move longitudinally. Each row of roller groups includes a plurality of rollers arranged along the longitudinal direction. For example, each row of roller groups may include two rollers arranged along the longitudinal direction. This embodiment is only an exemplary description, and other changes may be made according to the actual length of the entire workpiece or workpiece section to be supported. For example, if the length of the workpiece section to be supported is longer, the number of rollers in each row of roller groups may be more (for example, three, four or more, etc.) to provide support within a larger length range and provide greater rolling friction when driving the workpiece section to move; if the length of the workpiece section to be supported is shorter, the number of rollers in each row of roller groups may be less (for example, one). In addition, the number of rollers included in the two rows of roller groups may also be inconsistent. For example, in some embodiments, one row of roller groups includes one roller and the other row of roller groups includes two rollers, or one row of roller groups includes two rollers and the other row of roller groups includes three rollers, or one row of roller groups includes three rollers and the other row of roller groups includes four rollers. It should be noted that the above examples are not exhaustive and can be adjusted according to actual production needs. Furthermore, in some embodiments, the rollers in the two rows of roller groups are aligned with each other (regardless of whether the number of rollers in the two rows of roller groups is the same), but it is not limited to this. For example, in some embodiments, the rollers in the two rows of roller groups can also be staggered with a spacing of half a roller (regardless of whether the number of rollers in the two rows of roller groups is the same).

[0045] In some embodiments, the plurality of rollers each have an inner inclination angle, so that the roller surface of the roller contacts the circumferential surface of the workpiece, thereby increasing the contact area and being more conducive to driving the workpiece to move.

[0046] The roller group driving unit is used to drive the rollers in the corresponding roller group to rotate so as to drive the workpieces on the two rows of roller groups to move in the longitudinal direction. In some embodiments, the two rows of roller groups share a roller group driving unit, and the roller group driving unit drives the rollers in the two rows of roller groups to rotate simultaneously. In some embodiments, each row of roller groups in the two rows of roller groups corresponds to a roller group driving unit, and each roller group driving unit is used to drive the rollers in the corresponding row of roller groups to rotate. In some embodiments, the roller group driving unit may include a roller driving motor.

[0047] In actual applications, when the workpiece is placed horizontally on each carrier, the rollers in the roller group in each carrier are in contact with the workpiece, and the rollers in the respective roller groups are driven by the roller group driving units in each carrier, and the friction between the rollers and the workpiece drives the workpiece to move in the longitudinal direction relative to the carrier.

[0048] Of course, the workpiece transfer mechanism may still be modified in other ways. For example, in other embodiments, the workpiece transfer mechanism includes a roller conveying mechanism, a chain conveying mechanism, or a conveyor belt mechanism.

[0049] like Figure 3 and Figure 4 As shown, the carrier 21 also includes a support mechanism 214, which is used to support the bottom of the workpiece A when the workpiece A is cut. The support mechanism 214 is arranged on the support frame 211 and is located between the two rows of roller groups, and includes a support block and a support drive unit. When the support block is driven by the support drive unit, it can move upward and support the workpiece A after contacting the workpiece A. In some embodiments, the support block has an arc, so that the support surface of the support block (the support surface is located at the top of the support block) contacts the circumferential surface of the workpiece, increasing the contact area, and further ensuring the stability of the workpiece after being supported.

[0050] In some embodiments, the top supporting surface of the support block in the support mechanism 214 may also be provided with a supporting pad to avoid damaging the surface of the workpiece.

[0051] The support drive unit may be, for example, a brake cylinder (also referred to as a locking cylinder or a clamping cylinder), and the brake cylinder is provided with a brake device, which can control the control object with high precision, that is, can control the support block to brake or lock at the corresponding position. This embodiment is only an exemplary description, and as long as the workpiece supporting surface formed by the support blocks in each support mechanism can ensure the stability of the workpiece after supporting it, the number and layout of each support mechanism are not limited. For example, the number of support mechanisms can be changed according to the actual length of the entire workpiece or workpiece section that needs to be supported. If the length of the workpiece section to be supported is longer, the number of support mechanisms between each carrier can be more (for example, two, three, four, or more, etc.) to provide support within a larger length range. In addition, in some implementations, each carrier includes two rows of support mechanisms arranged in parallel along the lateral direction, and each of the support mechanisms has an inner inclination angle or arc surface, so that the top supporting surface of the support block (the top supporting surface is located at the top of the support block) contacts the circumferential surface of the workpiece to increase the contact area, further ensuring the stability of the workpiece after being supported.

[0052] like Figure 5 As shown, for the sake of distinction, the support mechanism disposed on the carrier on the proximal side of the guide rail is referred to as the tail support mechanism 2141, which is used to carry the tail workpiece segment after the truncation operation; the support mechanism disposed on the carrier on the distal side of the guide rail is referred to as the head support mechanism 2142, which is used to carry the head workpiece segment after the truncation operation. Since workpiece A is grown by the straight-pull method, the head of workpiece A is a tapered tip or a conical end. If there is a gap between the head support mechanism 2142 and the head of workpiece A, a jig can be used to pad between the head support mechanism 2142 and the head of workpiece A. Similarly, if there is a gap between the tail support mechanism 2141 and the tail of workpiece A, a jig can be used to pad between the tail support mechanism 2141 and the tail of workpiece A. In this way, the workpiece A can be stably supported by multiple support mechanisms.

[0053] In order to avoid the occurrence of edge collapse during the subsequent cutting of the workpiece, Figures 3 to 5 As shown, the carrier 21 also includes a first clamping mechanism 215, which is used to cooperate with the support mechanism 214 to clamp the workpiece A for subsequent cutting operation. The first clamping mechanism 215 is used to clamp the top of the workpiece A during the cutting operation. In some embodiments, the first clamping mechanism 215 includes a clamping member and a clamping driving unit, and the clamping member is driven by the clamping driving unit so that the clamping member clamps the top of the workpiece.

[0054] In certain embodiments, such as Figure 3 As shown, the pressing member includes a telescopic rod 2151 and a pressing rod 2152 .

[0055] The clamping member has a telescopic rod 2151 controlled by the clamping drive unit. In some embodiments, the clamping drive unit includes but is not limited to a cylinder. In practical applications, the telescopic rod 2151 can be driven by the cylinder to perform a telescopic movement so that the telescopic rod drives the clamping member to actuate. Specifically, the telescopic rod 2151 is associated with a clamping rod 2152. In this way, when the cylinder drives the telescopic rod 2151 to perform a contraction movement, the contracted telescopic rod 2151 pulls the clamping rod 2152 toward the supported workpiece and presses it against the workpiece; when the cylinder drives the telescopic rod 2151 to perform an extension movement, the extended telescopic rod 2151 pushes the clamping rod 2152 to move away from the supported workpiece.

[0056] The clamping member has a clamping rod 2152 for clamping the workpiece. In some embodiments, the clamping rod 2152 has a certain downward curvature, which can match the curvature of the circumferential surface of the workpiece to expand the force range of the workpiece on the circumferential surface. In some embodiments, an elastic element is also added to the clamping rod 2152, and the elastic element can be attached to the circumferential surface of the workpiece, and while clamping the workpiece, it has a buffering effect on the workpiece to prevent damage to the workpiece.

[0057] In some embodiments described in the present application, a lifting mechanism is further provided between the two rows of roller groups, and the lifting mechanism is used to lift the workpiece to adjust the horizontality of the axis of the workpiece. The lifting mechanism includes a lifting block and a lifting drive unit, and the lifting block is located between the two rows of roller groups and is configured as a plurality of blocks along the longitudinal direction, and the plurality of lifting blocks can be moved upward when being driven by the lifting drive unit. In some embodiments, the lifting drive unit includes but is not limited to a cylinder with a telescopic rod. In practical applications, the telescopic rod can be driven by the cylinder to perform a telescopic movement so that the telescopic rod drives the lifting block to move. When the cylinder drives the telescopic rod to extend, the extended telescopic rod pushes the lifting block to rise to lift the workpiece, and when the cylinder drives the telescopic rod to retract, the retracted telescopic rod drives the lifting block to descend so that the workpiece falls back to the supporting position of the two rows of roller groups. At this time, the horizontality of the axis of the workpiece can be adjusted manually or by a manipulator.

[0058] Taking silicon rods as an example, the position of the crystal lines on the silicon rods directly affects the processing quality of the silicon rods. For example, if the cutting device first contacts the crystal lines on the silicon rods during cutting or contacts the crystal lines last when passing through the silicon rods, it will cause edge collapse, and in severe cases, it will directly lead to the scrapping of the silicon rods. To prevent this phenomenon from happening, in some embodiments, the carrier also includes an adjustment mechanism for rolling and adjusting the crystal line position of the workpiece. The adjustment mechanism includes an adjustment component and an adjustment drive source. In some embodiments, the adjustment component is disposed on the carrier to drive the workpiece to roll. In some implementations, the adjustment component is two rows of rollers arranged in the transverse direction, and the axis lines of the two rows of rollers are arranged in the longitudinal direction and are parallel to the axis line direction of the workpiece, so that the workpiece can be driven to roll in the plane where X and Z are located to achieve the purpose of adjusting the crystal line position on the circumferential surface of the workpiece. For details, please refer to Figure 6 , which is a schematic diagram of the structure of the adjustment component in the carrier of the present application in one embodiment. As shown in the figure, the axis of the adjustment component 216 is along the longitudinal direction and is perpendicular to the axis of the workpiece transfer mechanism 213. In some embodiments, the adjustment drive source can be, for example, a rotary motor, which drives the associated adjustment component 216 to rotate to drive the workpiece to be cut to rotate, so that the position of the crystal line can be adjusted, thereby avoiding the cutting device from contacting the crystal line on the workpiece first or last during the cutting operation.

[0059] By using the multiple carriers in the present application, the loading operation of the workpiece to be cut can be realized. The loading operation is defined as the process of transferring the workpiece to be cut to the cutting station. At the same time, the end of the cutting station used for loading is defined as the loading end.

Figure 7 As shown, the cutting and square-cutting integrated device of the present application also includes a feeding conveying device 5 connected to the feeding end. The feeding conveying device 5 also includes a carrier frame 51, a bearing seat 52 is provided on the top of the carrier frame 51, and two rows of roller groups 53 are provided on opposite sides of the bearing seat 52. The two rows of roller groups 53 include a plurality of rollers arranged in sequence along the length of the carrier frame 51, and each roller can be connected to the bearing seat 52 through a bearing seat and protrude from the bearing seat 52. The rollers in the two rows of roller groups can form a supporting surface for supporting the workpiece A. After the workpiece A is horizontally placed on the two rows of roller groups of the bearing seat 52, the workpiece A can be directly pushed by the two rows of roller groups to convey the workpiece A and complete the workpiece feeding operation.

[0061] In some embodiments, the loading and conveying device 5 also includes a workpiece pushing mechanism. The workpiece pushing mechanism can be used to push the workpiece to move on the two rows of rollers alone or in cooperation with manpower. In some embodiments, the workpiece pushing mechanism can be, for example, a chain drive mechanism, including an endless chain, an ejector member provided on the endless chain, and a chain drive unit for the movement of the endless chain, the ejector member may include an ejector block or an ejector rod, and the chain drive unit may include a driving gear meshed with the endless chain and a driving motor associated with the driving gear. In practical applications, the driving motor drives the driving gear to rotate, and the driving gear drives the endless chain and the ejector block or ejector rod thereon, and the moving ejector block or ejector rod pushes the workpiece to move along the endless chain. In some embodiments, in the two-row roller group, in the transverse direction, the rollers in the first row of roller groups and the rollers in the second row of roller groups are opposite to each other to form a roller pair, and the two rollers in a roller pair can be connected through a rotating shaft, and the workpiece pushing mechanism includes a cascade chain driving mechanism, including a plurality of cascade chains and a driving motor. Specifically, the workpiece pushing mechanism is arranged on one side of the two-row roller group as a driving side, and the roller on the driving side in each roller pair is configured with a double driving gear. The cascade of all rollers in the two-row roller group is achieved by connecting two adjacent rollers in the longitudinal direction through a cascade chain (for example, a short ring chain) on a corresponding driving rack. The driving motor is also connected to the two-row roller group through a short ring chain and a driving gear. In actual application, the driving motor drives the driving gear to rotate, and drives all rollers in the two-row roller group to roll through the cascade chain, and drives the workpiece to move by means of the friction between the roller and the workpiece. Compared with ordinary chain drive mechanisms, cascade chain drive mechanisms can generate greater power, and all rollers rotate synchronously, ensuring smoother and more stable movement of workpieces.

[0062] In some embodiments, the lifting mechanism may also be arranged on the feeding conveying device, such as Figure 7 As shown, the loading and conveying device 5 also includes a lifting mechanism 54 for lifting the workpiece A to adjust the horizontality of the axis line.

[0063] In some embodiments, the adjustment mechanism may also be configured on the feeding conveying device, such as Figure 7 As shown, the loading and conveying device 5 also includes an adjustment mechanism 55, and its specific structure and function can be found in the above description, which will not be repeated here.

[0064] Under the coordinated action of the lifting mechanism 54 and the adjusting mechanism 55 , the crystal line of the workpiece A is in a suitable position.

[0065] In certain other embodiments, the adjustment mechanism may not be provided, and the crystal line position of the workpiece A can be adjusted manually. As long as the crystal line is in a suitable position and does not make the first and last contact with the cutting device, the present application does not impose any restrictions on this.

[0066] In actual application, after the workpiece A is transferred to the cutting station 11 by the loading and conveying device 5 and each carrier is moved to its respective supporting position, the lifting mechanism and the adjusting mechanism are used to lift the workpiece A and adjust the crystal line position on the workpiece A to a suitable position, and then the lifting mechanism is driven to make the workpiece A fall back to the supporting position of the two rows of roller groups; then, the clamping member in the first clamping mechanism 215 is controlled by the clamping drive unit to actuate and clamp the workpiece A supported by the carrier 21, and the roller group in the clamping member and the workpiece transfer mechanism is used to lift the workpiece A and adjust the crystal line position on the workpiece A to a suitable position. The workpiece A is positioned by cooperation; thereafter, the support block in the support mechanism 214 is controlled by the brake cylinder to rise and move until it touches the bottom of the workpiece A. At this time, the brake cylinder stops and locks the support block. The workpiece A is stably fixed under the support of the support block in the support mechanism 214 and the clamping of the clamping member of the first clamping mechanism 215, and is completely passed through by the cutting line segment of the cutting device 4 to realize the subsequent cutting operation. In this way, the edge collapse phenomenon in the cutting process can be effectively prevented, the flatness of the cut surface can be ensured, and the quality of the workpiece cutting can be improved.

[0067] Specifically, when the loading operation is performed, the support frame shifting mechanism 212 of the plurality of carriers 21 drives some or all of the carriers to converge to the loading end of the cutting station. Figure 2 As shown, all the carriers 21 are gathered at the feeding end to form an integral feeding and conveying group. In some embodiments, part of the carriers 21 are gathered at the feeding end to form an integral feeding and conveying group. For the carrier to be moved, the carrier is driven to move toward the feeding end in the longitudinal direction through the support frame shifting mechanism 212.

[0068] For example, in certain embodiments, when the length of the workpiece to be cut is certain and the workpiece will undergo head and tail truncation operations, the first carrier near the squaring area and the last carrier near the loading end can be fixedly arranged on the machine base, and the other carriers except the first carrier and the last carrier are sequentially moved along the longitudinal direction toward the loading end and converged to the loading end through their own support frame shifting mechanisms. Since the last carrier is fixedly arranged at the loading end of the machine base, when the other carriers converge to the loading end, in fact, the other carriers and the last carrier converge together. In the present application, the convergence includes each carrier being close to each other or each carrier being arranged in sequence at a certain distance. In other words, during the loading process, each carrier independently controls the gradual pulling and moving distance. As the workpiece moves on the truncation station, each carrier is finally evenly spaced relative to the length of the workpiece, as shown in the figure. Figure 5 The structural composition and working principle of the support bracket displacement mechanism can be found in the previous description, which will not be repeated here.

[0069] Subsequently, the workpiece transfer mechanisms of some or all of the carriers are driven to transfer the horizontally placed workpiece to be cut to some or all of the carriers, and the support frame shifting mechanisms of some or all of the carriers are driven to drive some or all of the carriers to move along the longitudinal direction toward the squaring position until the workpiece is transferred to the cutting position and each carrier is moved to its respective supporting position.

[0070] For example, in some embodiments, first, the workpiece transfer mechanisms of some or all of the carriers gathered together are driven, that is, for each carrier gathered together, the rollers in the roller group are driven to rotate by the roller group driving unit in the workpiece transfer mechanism; the horizontally placed workpiece is transported by a loading and conveying device and its head is transferred to the roller group of the workpiece transfer mechanism in the carrier closest to the loading end (that is, the last carrier) among the multiple carriers gathered together, and then, with the help of the loading and conveying device and the workpiece transfer mechanisms in each carrier, the workpiece to be cut can be transported to the subsequent carriers in sequence until the workpiece is transported as a whole to each of the gathered carriers; for each carrier gathered together, the roller group driving unit in the workpiece transfer mechanism of the carrier continues to drive the rollers in the roller group to rotate, and at the same time, the support frame shifting mechanism drives the corresponding support frame (that is, the carrier) to move along the longitudinal direction toward the square opening position, so that, on the one hand, the workpiece continues to be transported along the longitudinal direction toward the square opening position, and on the other hand, each carrier gradually disperses from each other while moving along the longitudinal direction. Finally, each carrier is moved to a corresponding supporting position and the workpiece is moved to a corresponding cutting position.

[0071] Next, the lifting drive unit is used to drive the lifting block to lift the workpiece A, and the horizontality of the axis line of the workpiece is adjusted manually or by a robot; the adjustment drive source is used to drive the adjustment component to drive the workpiece to rotate in the lateral direction, so as to adjust the position of the crystal line on the workpiece A to a suitable position. After the adjustment is completed, the lifting drive unit is used to drive the lifting block to make the workpiece fall back to the supporting position of the two rows of roller groups. Subsequently, the clamping member in the first clamping mechanism 215 is controlled by the clamping drive unit to actuate and clamp the workpiece supported on the carrier 21, and the workpiece is positioned through the cooperation of the clamping member and the roller group in the workpiece transfer mechanism 213; thereafter, the support block in the support mechanism 214 is controlled by the brake cylinder to move upward until it touches the bottom of the workpiece A. At this time, the brake cylinder stops and locks the support block. The workpiece A is stably fixed under the support of the support block in the support mechanism 214 and the clamping of the clamping member of the first clamping mechanism 215, and is completely passed through by the cutting line segment of the cutting device 4 to realize the subsequent cutting operation.

[0072] See also Figure 8 Combined with Figure 1 to Figure 2 , which is a schematic diagram of the structure of the cutting device of the present application in one embodiment. Figure 1 to Figure 2 As shown, the cutting device 4 is arranged on the machine base 1, and includes a frame and a line cutting unit. The frame is arranged on the machine base 1 and can move longitudinally relative to the machine base, and includes a support frame 41 and a cutting frame 42.

[0073] The support frame 41 is arranged on the machine base 1, and its specific form includes but is not limited to a beam, a column, a plate frame, a bracket, etc., which is used to drive the frame to move longitudinally. In some implementations, the support frame 41 is arranged across both sides of each carrier 21 and is arranged perpendicular to the truncation table 2. In order to ensure that there is no collision with each carrier, the shape of the support frame 41 can be configured as an "n" shape with an internal hollow, and the height of the hollow is greater than the height of each carrier to ensure that the support frame 41 can move longitudinally on the truncation table 2 without any hindrance.

[0074] In some implementations, the workpiece processing platform is provided with a translation rail arranged in the longitudinal direction, and a translation rack arranged in parallel with the translation rail. The translation rail runs through the entire truncation station 11 and the squaring station 12, and is located on opposite sides of the shifting groove. Through the translation rack and the translation rail, the support frame 41 can drive the entire frame to move longitudinally in the entire truncation area and the squaring area. In some implementations, the support frame 41 is arranged on the translation rail through a translation mechanism, and the translation mechanism includes a translation slider and a translation drive unit. The translation slider is located at the bottom of the support frame 41 and is mounted on the translation rail. The translation drive unit may include a translation drive gear and a translation gear drive motor associated with the translation drive gear. The translation drive gear is meshed with the translation rack. The translation gear drive motor drives the connected translation drive gear to rotate, and drives the engagement of the translation gear with the translation rack, thereby driving the support frame 41 to drive the entire frame body to move on the translation rail along the longitudinal direction in the entire truncation position and the squaring position.

[0075] Of course, the translation mechanism may still be modified in other ways. For example, in other implementations, the translation mechanism includes a chain conveying mechanism or a conveyor belt mechanism.

[0076] In one embodiment, the cutting frame 42 can be movably connected to the support frame 41 through a swing arm, and when the swing arm swings, the cutting frame 42 is driven to move up and down relative to the support frame. Here, the cutting frame 42 serves as a carrier for setting the wire cutting unit configured on the frame body, and its specific form can be a beam body, a column body, a plate frame, a bracket, etc. In some implementations, in conjunction with the labor-saving setting of the swing arm, a lifting mechanism is provided at one end of the swing arm connected to the support frame 41, and the other end is fixedly connected to the cutting frame.

[0077] The lifting mechanism may include a lifting rail, a slider, and a lifting drive unit, wherein the lifting rail is arranged on the support frame in a vertical direction, the slider is arranged on the support frame and is adapted to the corresponding lifting rail, and the lifting drive unit is used to drive the swing arm to drive the cutting frame to move up and down along the lifting rail. In actual applications, in order to enable the cutting frame to be stably lifted and lowered on the support frame, a three-rail design may be adopted, that is, three lifting rails are adopted, and the three lifting rails are arranged in parallel. In addition, the lifting drive unit may further include a lifting screw and a lifting motor, wherein the lifting screw is along the vertical direction and connected to the cutting frame, and the lifting motor (the lifting motor may be, for example, a servo motor) is connected to the lifting screw. In this way, the lifting motor drives the lifting screw to rotate, so that the cutting frame can be lifted and lowered along the lifting rail. The implementation method of the lifting drive unit is not limited to this. Other components that can drive the swing arm to drive the cutting frame to move up and down along the lifting guide rail are still applicable. For example, the lifting drive unit may include a lifting rack, a driving gear meshing with the lifting rack, and a driving motor that drives the gear to rotate.

[0078] In another embodiment of the present application, the connection assembly between the lifting mechanism and the lifting guide rail further includes a limit block for limiting excessive displacement of the lifting mechanism during the lifting movement.

[0079] In order to realize the cutting operation, the wire cutting unit is arranged on the cutting frame 42, and the workpiece is cut as the cutting frame 42 moves up and down relative to the support frame 41. The wire cutting unit is arranged on a mounting structure, and includes a plurality of cutting wheels, at least one transition wheel, and a cutting loop, and the cutting loop is sequentially wound around the cutting wheel and the transition wheel to form a cutting wire saw, which is used to perform the cutting operation and the squaring operation on the workpiece in sequence.

[0080] In such Figure 8 In the illustrated embodiment, the wire cutting unit includes two cutting wheels 421a, 421b, a tensioning wheel 422a, a driving wheel 422b, and a cutting loop 423. The cutting loop 423 is wound around the two cutting wheels 421a, 421b and the tensioning wheel 422a and the driving wheel 422b in an annular winding manner connected end to end, and then forms a cutting wire saw between the two cutting wheels 421a, 421b. The cutting wire saw is arranged in the transverse direction. The two cutting wheels 421a, 421b, the tensioning wheel 422a, the driving wheel 422b and the cutting loop 423 form a quadrilateral, which can be a rectangle or any quadrilateral.

[0081] The cutting loop 423 can maintain high-speed rotation during the entire cutting process, and at the same time, the cutting loop 423 can run in the same direction during the cutting process. In this way, the cutting device 4 of the present application can achieve high-precision cutting operations, avoiding the problems of the cutting surface having waviness or low flatness due to the reversal of the cutting line or the running speed in the existing cutting method; at the same time, the cutting loop can effectively reduce the total length of the cutting line required by the wire cutting unit and eliminate components such as the wire reel and the wire unwinding reel, reduce production costs and avoid the problem of uneven tension of the cutting line. The cutting wire saw formed by the cutting loop can move downward with the lifting mechanism to achieve cutting of the workpiece to be processed below the wire cutting unit. In the truncation operation of a lifting movement, the cutting wire saw completely passes through the workpiece to be truncation to truncate and form a workpiece segment. When the cutting loop moves longitudinally with the frame to the squaring position, in the squaring operation of a lifting movement, the cutting wire saw completely passes through the workpiece to be squaring to complete the squaring operation of the workpiece.

[0082] The cutting device 4 also includes a cutting line driving device for driving the cutting line 423 to run at high speed. In some embodiments, the cutting line driving device is a servo motor having a power output shaft and the power output shaft is connected to a cutting wheel or a transition wheel, so that the cutting line 423 can be driven by the wound cutting wheel and transition wheel to run at high speed along the winding direction. Of course, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the cutting line 423 to run, and this application does not limit it.

[0083] In some implementations, the driving wheel 422b is associated with a cutting line driving device. In some examples, the cutting line driving device includes a driving motor, the motor shaft of the driving motor is directly connected to the axle of the driving wheel 422b, and when the driving motor rotates, the motor shaft of the driving motor drives the driving wheel 422b to rotate, and the cutting line 423 is driven to run and the two cutting wheels 421a, 421b and the tensioning wheel 422a are rotated to achieve high-speed operation of the cutting line 423. In some examples, the cutting line driving device includes a driving motor and a transmission belt, and the transmission belt is sleeved on the motor shaft of the driving motor and the axle of the driving wheel 422b. When the driving motor rotates, the motor shaft of the driving motor drives the transmission belt to run and then drives the driving wheel 422b to rotate, and the cutting line 423 is driven to run and the two cutting wheels 421a, 421b and the tensioning wheel 422a are rotated to achieve high-speed operation of the cutting line 423.

[0084] In some embodiments, the tension wheel 422a also includes a tension adjustment mechanism. In the wire cutting process, the cutting line tension affects the yield and processing accuracy of the cutting process. The tension adjustment mechanism detects the tension and adjusts the tension so that the tension of the cutting line reaches a set threshold value and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value. The tension wheel 422a adjusts the tension of the cutting line 423 while guiding and traction the cutting line 423, which can reduce the probability of the cutting line breaking and reduce consumables.

[0085] In some embodiments, the tension adjustment mechanism at least includes: a vertical guide rail 424, a tension sensor, a servo motor and a screw rod; the vertical guide rail is vertically arranged on the cutting frame 42, and is used to drive the tension wheel 422a to move vertically. The tension sensor is arranged on the tension wheel 422a, and continuously senses the tension value of the cutting loop 423 on the tension wheel 422a, and sends a driving signal when the tension value is less than a preset value; the servo motor is electrically connected to the tension sensor, and is used to start working after receiving the driving signal sent by the tension sensor; one end of the screw rod is connected to the tension wheel 422a, and the other end is connected to the servo motor, and when the servo motor is working, the tension wheel 422a is pulled along the vertical guide rail 424 for unidirectional displacement to adjust the tension of the cutting loop 423.

[0086] In some embodiments, the tension adjustment mechanism includes: a connecting rod assembly and a tension driving unit, wherein the connecting rod assembly is associated with the tensioning wheel 422a and the tension driving unit, and the connecting rod assembly is controlled by the tension driving unit, that is, the tension driving unit drives the connecting rod assembly to drive the tensioning wheel 422a to change its position to adjust the tension of the cutting loop.

[0087] In some implementations, the tension driving unit may include a counterweight, which may be associated with a connecting rod assembly. When the tension of the cutting loop is to be increased, the counterweight is released, the counterweight is lowered, and the connecting rod assembly drives the tension wheel 422a to move under the action of the gravity of the counterweight, thereby expanding the circumference of the figure surrounded by the two cutting wheels 421a, 421b and the tension wheel 422a and the driving wheel 422b, and increasing the tension of the cutting loop 423. When the tension of the cutting loop is to be reduced, the counterweight is lifted, and the connecting rod assembly drives the associated tension wheel to move in the opposite direction under the action of the gravity of the counterweight, thereby reducing the circumference of the figure surrounded by the two cutting wheels 421a, 421b and the tension wheel 422a and the driving wheel 422b, and reducing the tension of the cutting loop 423. The counterweight part may include a counterweight block, wherein the number of the counterweight blocks may vary according to the requirement of adjusting the tension of the cutting loop. For example, when the tension of the cutting loop is increased, the number of the counterweight blocks may be increased, and when the tension of the cutting loop is reduced, the number of the counterweight blocks may be reduced. In some implementations, the tension driving unit may include a tension cylinder, and the tension cylinder is associated with a movable tension wheel. The tension cylinder is used to drive the associated tension wheel to move, and the tension of the cutting loop is adjusted by changing the position of the tension wheel.

[0088] In some embodiments, the tension adjustment mechanism may include a torsion motor and a torsion shaft, wherein the torsion motor is disposed on the cutting mounting structure, and the torsion shaft is associated with the torsion motor and the tension wheel 422a. When the tension of the cutting loop is to be increased, the torsion motor is driven to rotate in a first direction to drive the tension wheel 422a to make a first movement through the torsion shaft, thereby expanding the circumference of the figure surrounded by the two cutting wheels 421a, 421b and the tension wheel 422a and the driving wheel 422b, and increasing the tension of the cutting loop 423. When the tension of the cutting loop is to be reduced, the torsion motor is driven to rotate in a second direction to drive the tension wheel 422a to make a second movement through the torsion shaft, thereby reducing the circumference of the figure surrounded by the two cutting wheels 421a, 421b and the tension wheel 422a and the driving wheel 422b, and reducing the tension of the cutting loop 423.

[0089] When the workpiece is cut off, the cutting device 4 is driven by the translation mechanism to move longitudinally to the preset cutting position, and the cutting frame 42 is lowered along the support frame 41 through the swing arm, thereby driving the cutting loop 423 to descend. The cutting loop 423 is driven by the cutting wire driving device to run at high speed and continuously lower the cutting wire saw until the horizontally placed workpiece A is completely cut off to form a workpiece segment, and each workpiece segment is supported by at least one carrier 21.

[0090] After completing the cutting operation of a section of the workpiece, the carrier 21 and the cutting device 4 are moved to the far end to adjust the distance so as to leave a wire retreat space for the cutting wire saw.

[0091] Specifically, the distance that the carrier carrying the current workpiece section moves toward the distal end is greater than the distance that the cutting device moves toward the distal end, and the time when the carrier carrying the current workpiece section moves toward the distal end is earlier than the time when the cutting device moves toward the distal end.

[0092] by Figure 1 and Figure 2 Taking the embodiment shown as an example, the integrated cutting and squaring device of the present application includes a cutting device 4. When the cutting device 4 is used to cut the workpiece A, the cutting wire saw in the cutting device 4 completely passes through the workpiece A. In this way, after each cutting and forming a workpiece segment, the cutting wire saw in the cutting device 4 must be completely withdrawn. Therefore, the cutting device 4 and the carrier 21 corresponding to the workpiece segment formed by cutting are driven to move toward the distal end in the longitudinal direction to adjust the spacing, wherein the supporting distance of the carrier 21 corresponding to the workpiece segment formed by cutting moving toward the distal end in the longitudinal direction is greater than the cutting distance of the cutting device 4 moving toward the distal end in the longitudinal direction.

[0093] In certain embodiments, driving the cutting device 4 and the carrier 21 corresponding to the workpiece segment formed by the cutoff to move longitudinally toward the distal end for spacing adjustment may specifically include: starting from the distal end, first driving the carrier 12 corresponding to the workpiece segment formed by the cutoff to move longitudinally toward the distal end, and after a preset time interval, driving the cutting device 4 to move longitudinally toward the distal end, wherein a supporting distance of the carrier corresponding to the workpiece segment formed by the cutoff moving longitudinally toward the distal end (the distance moved by the carrier 21 is equal to the distance moved by the workpiece segment) is greater than a cutting distance of the cutting device 4 moving longitudinally toward the distal end, thereby leaving a wire withdrawal space for the cutting wire saw of the cutting device 4 (the distance between the workpiece segment and the workpiece body is greater than the distance between the cutting wire saw and the workpiece body, that is, the cutting wire saw is located between the workpiece segment and the workpiece body).

[0094] After the spacing adjustment is completed, the swing arm between the cutting frame 42 and the supporting frame 41 is used to drive the wire cutting unit of the cutting device 4 to move upward with the cutting wire saw relative to the frame body, and the wire withdrawal is completed through the wire withdrawal space.

[0095] When the workpiece segment is a head workpiece segment or a tail workpiece segment, the head workpiece segment or the tail workpiece segment placed horizontally can be transported away from the cutting table by manual or mechanical hands. Other workpiece segments formed by cutting can be transported away from the cutting table by the first transport device and placed on a forklift or other places where workpiece segments can be placed.

[0096] In some embodiments, the first transport device may be, for example, a robot. Fig. 9 , Fig. 9The diagram shows the structure of the first transport device in the integrated device of the present application. Fig. 9 As shown, the first piece transport device 6 is arranged on the machine base 1, and includes a first clamp, a second clamp, a clamp seat, and a clamp driving mechanism. The first clamp and the second clamp are arranged at opposite ends of the clamp seat, and are used to clamp the workpiece segment from the length direction of the workpiece segment. The clamp driving mechanism is used to drive at least one of the first clamp and the second clamp to move to adjust the clamping distance between the two clamps.

[0097] In some embodiments, the clamp driving mechanism may include: a screw rod and a driving source; wherein the screw rod is arranged along the length direction of the clamp seat and is associated with at least one of the first clamp and the second clamp; the driving source is used to drive the screw rod to rotate so that at least one associated clamp moves along the length direction of the clamp seat.

[0098] In some embodiments, the clamp driving mechanism may include a bidirectional screw and a driving source: the bidirectional screw is arranged along the length direction of the clamp seat and is associated with the first clamp and the second clamp at both ends; the driving source is used to drive the bidirectional screw to rotate so that the first clamp and the second clamp move toward or away from each other along the length direction of the clamp seat. The clamp driving mechanism is not limited to this, and it can also adopt a structure such as a telescopic rod and a driving cylinder or a driving hydraulic cylinder.

[0099] In order to realize the lifting and lowering movement of the first piece transporting device 6, and further realize the extraction action of the first clamp and the second clamp holding the workpiece segment at the cutting station and the placing action on a forklift or other place where the workpiece segment can be placed, the first piece transporting device also includes a piece transporting lifting mechanism, which is used to drive the first clamp and the second clamp to move up and down relative to the machine base in the vertical direction.

[0100] In some embodiments, the transport lifting mechanism may include a transport lifting guide rail and a transport lifting drive unit, wherein the transport lifting guide rail is arranged on the machine base in the vertical direction, and the transport lifting drive unit may include a transport lifting screw and a transport lifting motor, and the transport lifting screw is associated with the clamp seat. The transport lifting motor and the transport lifting screw can be used to drive the first clamp and the second clamp arranged on the clamp seat to move vertically along the transport lifting guide rail. For example, the transport lifting motor drives the transport lifting screw to rotate forward, and drives the transport fixture to move vertically upward along the transport lifting guide rail; the transport lifting motor drives the transport lifting screw to reverse, and drives the transport fixture to move vertically downward along the transport lifting guide rail. In some embodiments, the transport lifting mechanism may include a transport lifting guide rail, a transport lifting slider, and a transport lifting drive unit.

[0101] In order to realize the longitudinal movement of the first piece transport device 6 relative to the machine base 1, and then cooperate with the lifting and lowering movement of the first piece transport device 6 to realize the transportation of the clamped workpiece segment, a longitudinally extending piece transport translation guide rail is provided on the machine base, and matchingly, a piece transport translation slider is provided on the first piece transport device, and the piece transport translation slider is arranged on the clamping base and corresponds to the longitudinal guide rail.

[0102] In some embodiments, the transport mechanism further includes a transport translation drive unit, which may include: a transport translation rack, a transport translation gear and a transport translation drive motor, wherein the transport translation rack is longitudinally arranged on the machine base, the transport translation gear is arranged on the clamp seat and meshes with the transport translation rack, and the transport translation drive motor is used to drive the transport translation gear to rotate so that the associated clamp seat moves along the transport translation rack, thereby realizing the longitudinal movement of the first clamp and the second clamp. For example, the transport translation drive motor drives the transport translation gear to rotate forward, driving the first clamp and the second clamp to move longitudinally to the left along the transport translation rack; the transport translation drive motor drives the transport translation gear to rotate reversely, driving the first clamp and the second clamp to move longitudinally to the right along the transport translation rack.

[0103] In some embodiments, the workpiece translation drive unit may include a workpiece translation screw and a workpiece translation drive motor, wherein the workpiece translation screw is longitudinally arranged and associated with the clamp seat, and the workpiece translation drive motor is associated with the workpiece translation screw. The workpiece translation drive motor is used to drive the workpiece translation screw to rotate forward and reversely to drive the clamp seat to move left and right along the workpiece translation guide rail in the longitudinal direction, thereby realizing the longitudinal movement of the first clamp and the second clamp. For example, the workpiece translation drive motor drives the workpiece translation screw to rotate forward, and drives the first clamp and the second clamp to move to the left along the workpiece translation guide rail in the longitudinal direction; the workpiece translation drive motor drives the workpiece translation screw to reversely drive the first clamp and the second clamp to move to the right along the workpiece translation guide rail in the longitudinal direction.

[0104] Thereafter, the second transport device is used to transport the workpiece segments from the stacker or other places where the workpiece segments can be placed to the squaring table and transform the horizontal placement state into a vertical placement state. Fig.10, which is a schematic diagram of the structure of the second piece transport device in the cut-off integrated device of the present application. As shown in the figure, the second piece transport device 7 is arranged on the machine base 1, and is used to clamp the two end faces of the workpiece section B and change it from a horizontal state to a vertical state. In one embodiment, in order to stably clamp the two end faces of the workpiece section, the second piece transport device 7 may include four clamps evenly distributed along the outer circumference of the workpiece section B. The rest of the working methods and structures for transportation can refer to the description of the first piece transport device, and the present application will not repeat them here.

[0105] In other feasible embodiments, the first piece transport device 6 and the second piece transport device 7 can be configured as the same piece transport device, as long as the transfer of the workpiece segment B can be achieved, that is, whether it is transferred from the cut-off table to a forklift or other place where the workpiece segments are placed, or from a forklift or other place where the workpiece segments are placed to a square table, or directly from the cut-off table to an open table, the present application does not impose any restrictions on this.

[0106] like Figure 1 to Figure 2 As shown, in order to realize the squaring operation of the workpiece section, the squaring station in the cutting and squaring integrated equipment of the present application includes a squaring table 3. Fig.10 As shown, the squaring table includes a carrier 31 rotatably arranged on the squaring station for carrying a vertically placed workpiece segment. In one embodiment, the carrier 31 includes a rotating support, a rotating shaft, and a rotating drive source, the rotating support is fixedly connected to the rotating shaft, and the rotating drive source is associated with the rotating shaft, thereby driving the rotating support and the vertically placed workpiece segment B to rotate. In some implementations, the rotating drive source can be, for example, a rotating motor.

[0107] In order to protect the carrier from damage by the cutting loop during the squaring process of the workpiece, a cutting gasket 32 ​​is provided on the carrier 31, which is used to be cut together with the vertically placed workpiece segment B by the cutting loop 423 during the squaring operation. The material of the cutting gasket 32 ​​includes but is not limited to cheap materials such as polyvinyl chloride, so that it can be directly replaced when damaged. The size and dimensions of the cutting gasket 32 ​​match the end face of the workpiece segment B. It can be placed on the carrier 31 in advance before the squaring operation, or it can be attached to the end face of the workpiece segment B at the bottom, and then placed on the carrier 31 with the workpiece segment B. As long as it can be ensured that the cutting loop 423 completely passes through the end face of the workpiece segment B during squaring and does not contact the carrier 31, the present application does not impose any restrictions on this.

[0108] As mentioned above, in order to prevent the cutting loop on the cutting device from directly contacting the crystal line on the workpiece segment during the squaring operation to avoid edge collapse, in one embodiment, a crystal line mark is provided on the carrier 31 to indicate the crystal line position of the workpiece segment B placed vertically on the carrier 31, thereby prompting the cutting device 4 to avoid the crystal line position during the squaring operation, thereby preventing edge collapse and damage to the workpiece segment B during the squaring process. In another embodiment, the crystal line mark can also be directly provided on the cutting gasket 32 ​​and updated as the cutting gasket 32 ​​is replaced.

[0109] like Figure 8 As shown, in order to fix the workpiece segment B for squaring operation, a second clamping mechanism 43 is suspended on the cutting device 4, and the second clamping mechanism 43 corresponds to the supporting platform 31 and is used to clamp the workpiece segment B from the top during squaring operation.

[0110] For the convenience of description and distinction, the squaring operation of the workpiece segment B is divided into initial squaring and secondary squaring. The initial squaring refers to the process of removing the edges of the workpiece segment with a circular surface generated by the truncation operation to obtain a square rod and four edges, and the square rod is defined as a first-specification workpiece; the secondary squaring refers to the process of re-cutting the first-specification workpiece to obtain four small square rods, and the small square rods are defined as a second-specification workpiece.

[0111] See also Figure 11 to Figure 12 ,in, Fig.11 This is a schematic diagram showing the initial prescription at the prescription station for this application. Fig.12 The display is a schematic diagram of the status of re-opening the prescription at the prescription station for this application. Fig.11 As shown, when the workpiece segment B is initially squared to form a workpiece C of the first specification, the clamping position of the second clamping mechanism 43 is located at a position where the edge skin will be formed and does not affect the cutting of the cutting loop 423, and can prevent the edge skin from falling while fixing the workpiece segment B; Fig.12 As shown, when the first-specification workpiece C is squared again to form a second-specification workpiece, the second clamping mechanism 43 moves longitudinally by a certain distance to clamp the first-specification workpiece C without affecting the cutting of the cutting loop 423 .

[0112] In order to realize the longitudinal movement of the second clamping mechanism, the second clamping mechanism 43 includes a longitudinal adjustment structure for longitudinally adjusting the position of the top clamping the workpiece segment B or the first specification workpiece C. The longitudinal adjustment mechanism includes a longitudinal movement guide rail, a longitudinal movement slider, and a longitudinal movement drive unit.

[0113] The longitudinal movable guide rail is longitudinally arranged on the cutting device 4, the longitudinal movable slider is located at the top of the second clamping mechanism 43 and is mounted on the longitudinal movable guide rail, and matchingly, the cutting device 4 is also equipped with a longitudinal movable rack arranged in parallel with the longitudinal movable guide rail, and the longitudinal movable guide rail and the longitudinal movable rack enable the second clamping mechanism 43 to be longitudinally moved by the drive of the longitudinal movable driving unit through the longitudinal movable guide rail and the longitudinal movable rack. The longitudinal movable driving unit may include a driving gear and a gear driving motor associated with the driving gear, the driving gear is meshed with the longitudinal movable rack, and the gear driving motor drives the connected driving gear to rotate, and the meshing of the driving gear with the longitudinal movable rack drives the second clamping mechanism 43 to move longitudinally on the longitudinal movable guide rail.

[0114] In order to realize the clamping or lifting of the second clamping mechanism relative to the workpiece segment B or the first specification workpiece C, the second clamping mechanism 43 also includes a vertical adjustment structure, and the vertical adjustment mechanism includes a vertical movable guide rail, a vertical movable slider, and a vertical movable drive unit. The vertical movable guide rail is vertically arranged on the cutting device 4, and the vertical movable slider is mounted on the vertical movable guide rail. Matchingly, the cutting device 4 is also equipped with a vertical movable rack arranged in parallel with the vertical movable guide rail. Through the vertical movable guide rail and the vertical movable rack, the second clamping mechanism 43 can be driven by the vertical movable drive unit to achieve vertical movement. The vertical movable drive unit may include a driving gear and a gear drive motor associated with the driving gear, the driving gear is meshed with the vertical movable rack, and the gear drive motor drives the connected driving gear to rotate, and through the meshing of the driving gear and the vertical movable rack, the second clamping mechanism 43 is driven to move vertically on the vertical movable guide rail.

[0115] When performing the squaring operation, the cutting device 4 moves longitudinally to the preset squaring position, allowing the cutting loop 423 to run and continuously descend, and the cutting wire saw cuts from the end face of the workpiece segment B until the workpiece segment B is completely cut. After the cutting wire saw is reset, the support platform 31 is rotated to a preset angle to perform cutting on the other side.

[0116] Specifically, when the first squaring is performed, the second clamping mechanism 43 clamps the position where the edge of the workpiece segment B is about to be formed to prevent the edge from falling. The cutting device 4 is driven by the translation mechanism to move longitudinally to the preset squaring position. The cutting frame 42 descends along the support frame 41 through the swing arm, thereby driving the cutting loop 423 to descend. The cutting loop 423 runs at a high speed and continues to descend under the drive of the cutting line driving device. The cutting wire saw completely passes through the end face of the bottom of the vertically placed workpiece segment B to form a piece of edge. The second clamping mechanism 43 is in The vertical adjustment mechanism is driven to rise to loosen the edge skin, and the edge skin is taken away manually or by a robot; then, the cutting device 4 moves longitudinally for a certain distance to stay away from the remaining unsquared workpiece segment, and the cutting frame 42 rises along the support frame 41 through the swing arm, thereby driving the cutting loop 423 to rise to complete the withdrawal; the support platform 31 rotates 90° under the drive of the rotary drive source, and the second clamping mechanism 43 clamps the position of the second edge skin to be produced under the drive of the vertical adjustment mechanism, and then the cutting device 4 cuts to obtain the second edge skin. Repeat the above operation until the workpiece segment B is completely squared to obtain the first specification workpiece C.

[0117] When squaring again, the second clamping mechanism 43 moves longitudinally for a certain distance under the drive of the longitudinal adjustment mechanism, and presses one side of the first specification workpiece C under the drive of the vertical adjustment mechanism. The cutting device 4 moves longitudinally to the preset squaring position under the drive of the translation mechanism, and the cutting frame 42 descends along the support frame 41 through the swing arm, thereby driving the cutting loop 423 to descend. The cutting loop 423 runs at high speed and continues to descend under the drive of the cutting line driving device until the cutting wire saw completely penetrates the end surface of the bottom of the vertically placed first specification workpiece C and divides the first specification workpiece C into two; then, the two workpieces formed by manual longitudinal movement are cut to form a wire withdrawal space, and the cutting frame 42 rises along the support frame 41 through the swing arm, thereby driving the cutting loop 423 to rise to complete the wire withdrawal; the carrier 31 rotates 90° under the drive of the rotary drive source. Repeat the above operation until the first specification workpiece C is cut to obtain four second specification workpieces.

[0118] The following is a description of the execution process of the cut-off integrated device in the above embodiment with reference to the accompanying drawings:

[0119] First use the feeding conveyor device and Figure 3 and Figure 4The carriers shown in the figure cooperate to load the workpiece, and the support frame shifting mechanism of the multiple carriers drives some or all of the carriers to gather at the loading end of the cutting station to form an integrated loading and conveying group; then, the workpiece transfer mechanism of some or all of the carriers is driven to transfer the horizontally placed workpiece to be cut to some or all of the carriers, and the support frame shifting mechanism of some or all of the carriers is driven to drive some or all of the carriers to move along the longitudinal direction toward the squaring position until the workpiece is transferred to the cutting position and each carrier is moved to its respective supporting position; then, the lifting drive unit is used to drive the lifting block to lift the workpiece, and the horizontality of the axis line of the workpiece is adjusted manually or by a robot; The adjustment driving source drives the adjustment component to drive the workpiece to rotate in the lateral direction, so as to adjust the position of the crystal line on the workpiece to a suitable position. After the adjustment is completed, the workpiece falls back to the initial supporting position on each carrier under the drive of the adjustment driving source; the clamping member in the first clamping mechanism is controlled by the clamping driving unit to actuate and clamp the workpiece supported by the carrier, and the workpiece is positioned through the cooperation of the clamping member and the roller group in the workpiece transfer mechanism; thereafter, the support block in the support mechanism is controlled by the brake cylinder to rise and move until it touches the bottom of the workpiece, at which time the brake cylinder stops and locks the support block, and the workpiece is stably fixed under the top support of the support block in the support mechanism and the clamping of the clamping member of the first clamping mechanism, and then the workpiece is fixed by the clamping member of the first clamping mechanism. Figure 8 The cutting device shown performs a cutting operation on the workpiece. The cutting device is driven by the translation mechanism to move longitudinally to a preset cutting position. The cutting frame is lowered along the support frame through the swing arm, thereby driving the cutting wire to descend. The cutting wire is driven by the cutting wire driving device to run at a high speed and continuously lower the cutting wire saw until the horizontally placed workpiece is completely cut off to form a workpiece section. Each workpiece section is supported by at least one carrier. After completing the cutting operation of a section of the workpiece, the carrier and the cutting device are moved to the far end to adjust the spacing so as to leave a wire withdrawal space for the cutting wire saw. The cutting device uses the swing arm between the cutting frame and the support frame to drive the wire cutting unit to move upward with the cutting wire saw relative to the frame body, and complete the wire withdrawal through the wire withdrawal space.

[0120] After the head is cut off, the head workpiece segments are cut manually or by a robot, and the remaining workpiece segments are cut using Fig. 9 The first transport device shown in the figure is transported away from the cutting table and placed on a forklift or other place where the workpiece section can be placed. Thereafter, the first transport device is used as shown in the figure. Fig.10The second transport device shown transports the workpiece segment from a stacker or other place where the workpiece segment can be placed to the support platform of the squaring table and changes it from a horizontal placement state to a vertical placement state. The cutting device is moved longitudinally to the preset squaring position, the crystal line is adjusted to a suitable position according to the crystal line mark on the support platform, and the edge position of the workpiece segment is clamped by the second clamping device. Since the center of the cutting station 11 is orthogonal to the vertical axis of the squaring station and is located on the same plane, it is not necessary to adjust the angle of the cutting device in the X direction before the initial squaring operation. The cutting frame can be directly lowered along the support frame through the swing arm, thereby driving the cutting loop to descend. The cutting loop is driven by the cutting line driving device to run at high speed and continuously descend the cutting wire saw until the workpiece is lowered from the vertical position. The end surface of the cut bottom is completely penetrated to form a side skin, and the second clamping mechanism is driven by the vertical adjustment mechanism to rise to loosen the side skin, and the side skin is taken away manually or by a robot; then, the cutting device moves longitudinally for a certain distance to stay away from the remaining unsquared workpiece segment, and the cutting frame rises along the support frame through the swing arm, thereby driving the cutting loop to rise to complete the withdrawal; the support platform rotates 90° under the drive of the rotary drive source, and the second clamping mechanism is driven by the vertical adjustment mechanism to clamp the position of the second side skin to be produced, and then the cutting device cuts to obtain the second side skin. After four cuts, the first square of the workpiece segment is completed to obtain a workpiece of the first specification.

[0121] Then, the first specification workpiece is squared again. The second clamping mechanism moves longitudinally for a certain distance under the drive of the longitudinal adjustment mechanism, and presses one side of the first specification workpiece under the drive of the vertical adjustment mechanism. The cutting device moves longitudinally to the preset squared position under the drive of the translation mechanism. The cutting frame descends along the support frame through the swing arm, thereby driving the cutting loop to descend. The cutting loop runs at high speed and continues to descend under the drive of the cutting line driving device until the cutting wire saw completely penetrates the end surface at the bottom of the vertically placed first specification workpiece and divides the first specification workpiece into two. The two workpieces formed by manual longitudinal movement cutting are used to form a wire withdrawal space. The cutting frame rises along the support frame through the swing arm, thereby driving the cutting loop to rise to complete the wire withdrawal. The bearing table rotates 90° under the drive of the rotary drive source. After two cuts, the first specification workpiece is squared again to obtain four second specification workpieces.

[0122] Finally, the second specification workpiece is cut manually or by a robot after the squaring operation is completed.

[0123] To summarize, in order to overcome the technical problems existing in the related art that when cutting and squaring the workpiece, each process operation is arranged independently and the operating equipment is scattered, and the conversion of workpieces performing different process operations requires transportation and allocation, resulting in low processing efficiency and low product qualification rate, the integrated cutting and squaring equipment provided by the present application integrates the workpiece cutting operation and the squaring operation on the same equipment, thereby reducing the number of manual handling of the workpiece, thereby reducing the risk of workpiece damage, improving the product qualification rate, and improving the workpiece processing efficiency; in particular, the integrated cutting and squaring equipment of the present application sets the cutting station center and the squaring station center on the same axis, which not only simplifies the equipment footprint, but also allows two different cutting processes to share the same cutting frame without the need for additional adjustment of the cutting frame, thereby saving the space occupied by the operating equipment while also improving the cutting operation efficiency; furthermore, the present application uses the same cutting device loop to perform both cutting and squaring operations on the workpiece, thereby reducing the repeated winding of the cutting line, thereby simplifying the equipment structure and saving production costs.

[0124] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
