Description

Technical Field

[0001] The present application relates to the technical field of silicon workpiece processing, and in particular to an integrated device for cutting and grinding small rectangular bars, a method for cutting and grinding small rectangular bars, a cutting device for small rectangular bars, and a grinding device for small rectangular bars. Background Art

[0002] In order to improve the conversion efficiency of photovoltaic modules, shingled modules came into being. Shingled modules refer to multiple cells connected in series in the form of front-to-back stacking. There is no gap between the cells, and no welding strips to block the cells. Therefore, more cells can be accommodated under the same area of ​​the module, expanding the effective power generation area. In the current related technology, in order to obtain silicon wafers for making shingled modules, it is necessary to first make silicon rods that can be sliced ​​into silicon wafers. Silicon rods are usually made by re-cutting and grinding the square silicon rods made in the original process.

[0003] In the relevant processing technology for silicon rods, several processes such as squaring, grinding, rounding / chamfering are involved. Generally, most of the existing silicon rods are cylindrical structures. The silicon rods are squared by silicon rod squaring equipment, so that the cross-section of the silicon rods after squaring is rectangular (including square), and the squared silicon rods are rectangular as a whole (may also include cube-like shapes). Quasi-rectangles include rectangles with adjacent sides orthogonal or angles within a predetermined angle, rectangles with rounded corners between adjacent sides, rectangles with connecting short sides between adjacent sides, etc.

[0004] Taking a single crystal silicon rod as an example, in some related technologies, the process of forming a single crystal silicon rod may include: first using a silicon rod cutter to cut the original long silicon rod to form multiple short silicon rods; after the cutting is completed, using a silicon rod squarer to square the short silicon rod to form a single crystal silicon rod with a rectangular cross section. Among them, the specific implementation method of using a silicon rod cutter to cut the original long silicon rod to form multiple short silicon rods can refer to patent disclosures such as CN105856445A, CN105946127A, and CN105196433A, and the specific implementation method of using a silicon rod squarer to square the short silicon rod to form a single crystal silicon rod with a rectangular cross section can refer to patent disclosures such as CN105818285A. However, the process for forming a single crystal silicon rod is not limited to the aforementioned technology. In an optional example, the process for forming a single crystal silicon rod may also include: first, using a full silicon rod squaring machine to square the original long silicon rod to form a long single crystal silicon rod with a rectangular cross section; after the square is cut, using a silicon rod cutting machine to cut the squared long single crystal silicon rod to form a short silicon rod. Among them, the specific implementation method of using a full silicon rod squaring machine to square the original long silicon rod to form a rectangular long single crystal silicon rod can be referred to, for example, patent disclosures such as CN106003443A.

[0005] After the cylindrical single crystal silicon rod is cut into a silicon rod with a rectangular cross section by using a squaring device, the rectangular silicon rod can be ground, rounded, chamfered, etc. by using a grinding device. The specific implementation of the grinding, rounding, chamfering, etc. of the rectangular silicon rod by the grinding device can refer to patent disclosures such as CN105835247A.

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

[0007] However, there is no good dedicated equipment for cutting and grinding original silicon rods in the prior art. In the existing equipment technology, the operations required for each process (such as cutting in half, grinding, etc.) are arranged independently, and the corresponding processing equipment is scattered in different production units or production workshops or different production areas of production workshops. The conversion of workpieces performing different process operations requires transportation and allocation, and pretreatment may be required before performing each process operation. In this way, the process is complicated and inefficient, and it is easy to affect the quality of silicon rod processing operations, 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 workpiece damage during the workpiece transfer process, and is prone to non-production factors. Unqualified products reduce the product qualification rate and the unreasonable losses caused by the existing processing methods. Summary of the invention

[0008] In view of the shortcomings of the related technologies mentioned above, the purpose of the present application is to provide an integrated cutting and grinding device for small-sized rectangular rods, which is used to solve the problems existing in the existing related technologies such as complex equipment, inconvenient operation, poor cutting quality and low efficiency.

[0034] The cutting machine base is the main component of the half-rod cutting equipment and is used to provide a processing platform. In practical applications, the cutting machine base is large in size and weight to provide a large mounting surface and a firm overall stability. It should be understood that the cutting machine base can be used as a base for different structures or components that perform processing operations in the half-rod cutting equipment, and the specific structure of the cutting machine base can be changed based on different functional requirements or structural requirements. In some examples, the cutting machine base includes a fixed structure or a limiting structure such as a base, a column, a frame, etc. for receiving different components in the half-rod cutting equipment, which are all the cutting machine bases of the present application.

In some embodiments, the cutting processing platform is provided with one or more cutting station groups, each of which includes a first cutting station and a second cutting station arranged in parallel.

However, this is not limited to this, please refer to Figure 4 , which is a schematic diagram of the structure of the half-rod cutting device in another embodiment. Figure 4 In the embodiment shown, the cutting processing platform of the half-rod cutting device is provided with two cutting station groups, wherein each cutting station group includes a first cutting station and a second cutting station arranged in parallel along the second direction. Figure 1 and Figure 2 In the embodiment shown, or in the Figure 4 In the illustrated embodiment, a first silicon rod transfer device 12 and a first silicon rod cutting device 13 are arranged corresponding to the first cutting station, and a second silicon rod transfer device 14 and a second silicon rod cutting device 15 are arranged corresponding to the second cutting station.

[0037] The first cutting station includes a first loading and unloading area and a first cutting area. The first cutting station is equipped with a first silicon rod transfer device, which is used to carry a silicon rod with a circular cross section and transfer it between the first loading and unloading area and the first cutting area along a transfer direction. The first silicon rod cutting device is arranged in the first cutting area. The first silicon rod cutting device is provided with at least one first cutting wire saw, which is located in a vertical plane and arranged along the vertical direction or arranged at an angle to the vertical direction. The first silicon rod cutting device and the first silicon rod transfer device are relatively moved along the transfer direction so that the silicon rod with a circular cross section is first cut by at least one first cutting wire saw, so that the silicon rod forms two parallel first side cut surfaces. The vertical plane is composed of the first direction and the third direction.

[0038] The first silicon rod transfer device is used to carry the silicon rod and transfer it between the first loading and unloading area and the first cutting area of ​​the first cutting station along the transfer direction, wherein the silicon rod (circular in cross section) is placed horizontally on the first silicon rod transfer device and the axis of the silicon rod is consistent with the transfer direction, and the transfer direction is consistent with the first direction.

[0040] The first carrying platform is arranged on the first transfer channel for carrying the silicon rods. After being carried by the first carrying platform, the silicon rods are in a horizontal position, that is, the axis of the silicon rods is consistent with the transfer direction (that is, the first direction).

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

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

[0044] In some implementations, see Figure 6 , which is a schematic diagram showing a structure including a first silicon rod transfer device. Figure 6 As shown, the first carrier 121 is a Y-shaped carrier structure as a whole. The first carrier can adopt a Y-shaped carrier structure. The bottom of the Y-shaped carrier structure serves as a bearing bracket, and the upper fork of the Y-shaped carrier structure serves as a first bearing structure, wherein the inner inclined surface of the upper fork contacts the arc surface of the silicon rod to be cut. Among them, the top of the upper fork of the Y-shaped carrier structure may also have a certain width. When the Y-shaped carrier structure is used to carry the silicon rod to be cut placed horizontally, the upper fork of the Y-shaped carrier structure (i.e., the V-shaped part) carries the silicon rod to be cut, and the two inner inclined surfaces of the upper fork contact the arc surface of the silicon rod to be cut. In this way, the silicon rod to be cut with a circular cross-section can also be centered, that is, the axis of the silicon rod to be cut corresponds to the center of the upper intersection (i.e., the bottom groove of the V-shaped part).

Wherein, when at least two first carriers in the first carrier platform are to be configured with the carrier driving unit, the adjustment rack may be shared. For example, when there are two first carriers to be configured with the above-mentioned first carrier driving unit, it may include a shared adjustment rack, a first adjustment gear and a first adjustment drive source associated with the first first carrier, and a second adjustment gear and a second adjustment drive source associated with the second first carrier.

When there are two first carriers to be equipped with the above-mentioned first carrier driving unit, it may include a bidirectional screw and a screw driving source, and the two ends of the bidirectional screw are respectively provided with threads and the thread directions are opposite, and the two ends of the bidirectional screw are respectively associated with the two opposite first carriers. In practical applications, the bidirectional screw is driven to rotate by a screw driving source (such as a servo motor) so that the two associated opposite first carriers move toward each other (the two first carriers approach each other) or move away from each other (the two first carriers move away from each other) along the bidirectional screw. The first transfer driving mechanism is used to drive the first carrier platform and the silicon rods it carries to move on the first transfer channel along the transfer direction.

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

[0051] In some embodiments, the first transfer drive unit includes: a transfer rack, a transfer gear, and a gear drive source. The transfer rack is arranged along the transfer direction. The transfer gear is associated with the first load-bearing platform and meshes with the transfer rack. In some embodiments, the transfer gear is associated with at least two first load-bearing members in the first load-bearing platform. The transfer gear can be associated with at least two first load-bearing members in the first load-bearing platform in the following manner: at least two first load-bearing members are connected by a connecting structure (such as a frame, a connecting plate, a connecting frame, etc.), and the driving gear is arranged on the connecting structure. The gear drive source is used to drive the transfer gear to rotate so that the associated first load-bearing platform moves along the transfer direction. The gear drive source can be, for example, a servo motor.

[0052] In some embodiments, the first transfer drive unit includes: a transfer screw and a screw drive source. The transfer screw is arranged along the transfer direction and is associated with the first bearing platform. In some embodiments, the transfer screw is associated with at least two first bearing members in the first bearing platform.

Therefore, in some embodiments, the function of the first carrier driving mechanism for driving at least one first carrier to move along the transfer direction to adjust the bearing spacing between the two first carriers can be accomplished by the first transfer driving mechanism.

[0058] In some embodiments, multiple first cutting wheels in the first wire cutting unit are connected to the first cutting mounting structure, or, multiple first cutting wheels are arranged on the first cutting mounting structure through a bracket, a connecting plate, or a mounting frame. The first cutting mounting structure serves as a carrier for associating the multiple first cutting wheels in the first wire cutting unit with the first cutting frame or the first cutting seat.

[0062] In some embodiments, the first cutting line is wound between the first cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Figure 2 (or Figure 4 )and Figure 5 In the illustrated embodiment, the first cutting line 134 is wound between the plurality of first cutting wheels 132 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0063] The multiple first cutting wheels in the first cutting unit are wound by a circular cutting wire. In this example, the first silicon rod cutting device can omit the wire storage drum, and the circular cutting wire can be driven by the cutting wire driving device to maintain high-speed operation. At the same time, the circular cutting wire can run in the same direction during the cutting operation. In this way, the first silicon rod cutting device can achieve high-precision first cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire operation or the running speed in the existing cutting method; at the same time, the circular cutting wire can effectively reduce the total length of the cutting wire required by the first wire cutting unit, thereby reducing production costs.

[0064] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to the first cutting wheel, so that the first cutting line can be driven by the wound second cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the first cutting line to run, and this application does not limit it.

[0065] The first wire cutting unit in the present application may further include a first transition wheel, which is used to change direction or guide the first cutting wire, or the first transition wheel may be used to adjust the tension of the first cutting wire. The number of the first transition wheels may be one or more according to layout requirements.

[0066] The first transition wheel, while guiding and pulling the first cutting line, also serves as a tension wheel for adjusting the tension of the first cutting line. The tension wheel is used to adjust the tension of the first cutting line, which can reduce the probability of the first cutting line breaking and reduce consumables.

[0067] like Figure 5 As shown, in the first wire cutting unit, the first cutting installation structure 130 is a rectangular frame as a whole, and each first wire cutting unit 131 includes a plurality of first cutting wheels 132 and a plurality of first transition wheels 133, for example, two first cutting wheels 132 and two first transition wheels 133, which are respectively arranged near the four corners of the first cutting installation structure 130, and the wheel surfaces of the two first cutting wheels 132 and the two first transition wheels 133 are both located in the vertical plane, wherein the two first cutting wheels 132 are in the front and arranged in parallel up and down, and the two first transition wheels 133 are in the back and arranged in parallel up and down, and the first cutting wire 134 is wound around the two first cutting wheels 132 and the two first transition wheels 133 to form at least one first cutting wire saw 135 (for example, a first cutting wire saw 135 is formed between the two first cutting wheels 132), and at least one first cutting wire saw 135 is arranged vertically.

[0068] As before, the first cutting line 134 is wound around multiple first cutting wheels 132 or multiple first cutting wheels 132 and multiple first transition wheels 133 to form a first cutting line saw 135 between the two preceding first cutting wheels 132. Therefore, to adjust the line length of the first cutting line saw 135, the spacing between the two first cutting wheels 132 can be adjusted, and the implementation method includes changing the position of at least one of the two first cutting wheels 132.

[0069] The first cutting wire saw is located in the vertical plane and is arranged along the vertical direction or at an angle to the vertical direction, and the silicon rod to be cut carried by the first silicon rod transfer device at the corresponding first cutting station is placed horizontally (the axis of the silicon rod to be cut is arranged along the transfer direction). Therefore, in order to achieve the cutting of the silicon rod to be cut, the length of the first cutting wire saw is adapted to the size of the end face of the silicon rod to be cut. For example, the length of the first cutting wire saw must be greater than or equal to the diameter of the silicon rod to be cut or the chord length of the silicon rod to be cut at the cutting position.

[0070] The direction of the first cutting wheel surface corresponds to the direction of the first cutting wire saw. It should be understood that the first cutting wheel surface is parallel to the plane where any first cutting wire groove in the first cutting wheel is located. In order to control the cutting accuracy and the stability of the cutting process, the first cutting wire saw should be located in the plane where the first cutting wire groove for winding the first cutting wire is located; at the same time, during the cutting process, the force direction of the silicon rod on the first cutting wire must be parallel to the cutting wire groove, that is, the cutting wheel surface is parallel to the cutting direction. The cutting direction in the first cutting operation is the direction of the silicon rod axis, that is, the transfer direction (that is, the first direction X-axis).

[0071] The first silicon rod cutting device includes two first wire cutting units arranged in parallel, each of which has a first cutting wire saw, so the two first wire cutting units form two parallel cutting wire saws. Figure 5 In the illustrated embodiment, the first silicon rod cutting device comprises two first wire cutting units arranged in parallel along the second direction, each first wire cutting unit has a first cutting wire saw, and the first cutting wire saw is arranged vertically. Thus, the two first cutting wire saws belonging to the two first wire cutting units are arranged vertically.

[0072] In fact, the first cutting wire saw may still have other changes. In some embodiments, the first cutting wire saw is arranged along the vertical direction, but it is not limited to this. In other embodiments, the position of the first cutting wire saw may be located in the vertical plane and arranged at an angle to the vertical direction (i.e., the third direction). The vertical plane is composed of the first direction and the third direction, and the angle is less than or equal to 10 degrees (≤10°), or the angle is less than or equal to 5 degrees (≤5°), or the angle is less than or equal to 3 degrees (≤3°). That is, the routing direction of the first cutting wire saw may be located in the vertical plane with the third direction (i.e., the vertical direction) and form an angle of less than or equal to 10 degrees (≤10°), less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°) with the third direction (i.e., the vertical direction). The angle here is not limited to an integer angle, and it may be any angle within a limited range, for example, 0.09°, 1.3°, 2.5°, 3°, etc. In some embodiments, when forming two first cutting wheels arranged up and down to form a first cutting wire saw, the upper first cutting wheel is in front in the first direction and the lower first cutting wheel is in the back in the first direction, and the first cutting wire saw formed can form a positive deflection angle with the vertical. In some embodiments, when forming two first cutting wheels arranged up and down to form a first cutting wire saw, the upper first cutting wheel is in the back in the first direction and the lower first cutting wheel is in the front in the first direction, and the first cutting wire saw formed can form a negative deflection angle with the vertical. The deflection angle (including positive deflection angle and negative deflection angle) can be changed according to the cutting process requirements and the size specifications of the silicon rod, for example, the angle of the deflection angle can be adjusted by changing the position of one or both of the two first cutting wheels arranged up and down related to the first cutting wire saw.

[0073] In some embodiments, the first wire cutting unit further includes a first tension adjustment mechanism. In wire cutting processing, the cutting wire tension affects the yield and processing accuracy of cutting, and the first tension adjustment mechanism performs tension detection and adjusts the tension so that the tension of the first cutting wire reaches a certain threshold value set and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0074] In an embodiment, the first tension adjustment mechanism is associated with the first transition wheel 133 or the first cutting wheel. The first transition wheel 133 in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while guiding and traction of the first cutting wire 134 .

[0075] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, current wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0076] In some embodiments, taking the tensioning wheel as the transition wheel as an example, the tension adjustment mechanism at least includes: a tension sensor, a servo motor and a screw rod; the tension sensor is arranged on the transition wheel, continuously senses the tension value of the cutting line on the transition wheel, 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 transition wheel, and the other end is connected to the servo motor, and when the servo motor is working, it pulls the transition wheel for unidirectional displacement to adjust the tension of the cutting line.

[0077] In some embodiments, the tension adjustment mechanism includes: a connecting rod assembly and a tension driving unit, the connecting rod assembly is associated with a transition wheel serving as a tensioning wheel 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 transition wheel to change its position to adjust the tension of the closed-loop cutting line.

[0078] Regarding the tension driving unit, in certain implementations, the tension driving unit may include a counterweight portion, and the counterweight portion may be associated with a connecting rod assembly. For example, taking a certain transition wheel as a tensioning wheel, when the tension of the closed-loop cutting line is to be increased, the counterweight portion is released, the counterweight portion is lowered, and the connecting rod assembly is driven by the gravity of the counterweight portion to move the associated tensioning wheel, thereby expanding the circumference of the figure surrounded by each cutting wheel and the transition wheel, and increasing the tension of the closed-loop cutting line. When the tension of the closed-loop cutting line is to be reduced, the counterweight portion is lifted, and the connecting rod assembly is driven by the gravity of the counterweight portion to move the associated tensioning wheel in the opposite direction, thereby expanding the circumference of the figure surrounded by each cutting wheel and the transition wheel, and reducing the tension of the closed-loop cutting line.

[0079] The counterweight part may include counterweight blocks, wherein the number of counterweight blocks may vary according to the requirements of closed-loop cutting line tension adjustment. For example, when the tension of the closed-loop cutting line is increased, the number of counterweight blocks may be increased, and when the tension of the closed-loop cutting line is reduced, the number of counterweight blocks may be reduced.

[0080] In some embodiments, the counterweight may include a locking mechanism for locking the counterweight so that the counterweight is stationary relative to the cutting mounting structure, so that the counterweight and the cutting mounting structure are switched from an active state to a locked state. In some examples, the locking mechanism may be, for example, a latch.

[0081] The tension driving unit may still be modified in other ways. For example, in some implementations, the tension driving unit may include a tension cylinder.

[0082] In some embodiments, the first silicon rod cutting device further comprises: at least one first distance adjustment mechanism, provided in at least one first wire cutting unit, for driving a plurality of first cutting wheels in the first wire cutting unit to move in a direction perpendicular to the wheel surface of the cutting wheel. The first silicon rod cutting device can realize the switching of the first cutting wire between different cutting grooves of the first cutting wheel based on the distance adjustment mechanism, or adjust the position of the first cutting wire saw to change the cutting position (or processing specification) relative to the silicon rod.

[0083] In certain implementations, a first wire cutting unit in a first silicon rod cutting device is used as an example for description, and the first wire cutting unit includes a plurality of first cutting wheels and a plurality of first transition wheels. The carrier for carrying the plurality of first cutting wheels and the first transition wheel is, for example, a first cutting mounting structure, and the first distance adjustment mechanism can be used to drive the first cutting mounting structure as a whole to move along the perpendicular direction of the wheel surface of the cutting wheel, and the first transition wheel and the first cutting wheel move together with the first cutting mounting structure along the perpendicular direction of the wheel surface of the first cutting wheel (i.e., the transposition direction or the second direction Y axis). In this state, the plurality of first cutting wheels and the first transition wheel are relatively stationary, that is, the positional relationship between the first transition wheel and the first cutting wheel remains unchanged. At this time, the first distance adjustment mechanism is used to adjust the cutting position of at least one first wire cutting wire saw in at least one first wire cutting unit relative to the silicon rod.

[0084] In some implementations, each first cutting wheel has at least two first cutting grooves, different first cutting grooves are parallel to each other and there is a cutting offset in the direction perpendicular to the wheel surface of the first cutting wheel between different first cutting grooves. When the first distance adjustment mechanism is used to drive the multiple first cutting wheels in the first wire cutting unit to move relative to the first cutting mounting structure, the position of the groove around which the first cutting wire is wound on the first cutting wheel can be changed. In some implementations, the multiple first cutting wheels in the first wire cutting unit can be connected to a bracket, for example, wherein the bracket is movably arranged on the first cutting mounting structure and driven by the first distance adjustment mechanism to move along the direction perpendicular to the wheel surface of the first cutting wheel.

[0085] When at least one first distance adjustment mechanism is used to realize the change of the cutting wire grooves of the first cutting wire wound around the multiple first cutting wheels in the at least one first wire cutting unit, in an actual scenario, the first cutting wire grooves corresponding to the cutting wires before and after the groove change can be predetermined, for example, the position of the first cutting wire before the groove change is the first cutting wire groove a1, and the first cutting wire is wound around the first cutting wire groove a2 after the groove change, and the displacement amount of the multiple first cutting wheels in the first wire cutting unit driven by the first distance adjustment mechanism is determined based on the cutting offset between the first cutting wire groove a1 and the first cutting wire groove a2, that is, the displacement amount is set as the first cutting wire groove The cutting offset between groove a1 and the first cutting wire groove a2 can be used to realize the replacement of the first cutting wire from the first cutting wire groove a1 to the first cutting wire groove a2; it should be noted that at least one first distance adjustment mechanism drives the multiple first cutting wheels in the first wire cutting unit to move in the direction perpendicular to the wheel surface of the first cutting wheel in the direction in which the cutting wire groove a2 points to the cutting wire groove a1. After the groove is changed, the cutting position of the first cutting wire saw in space remains unchanged, and the step of further calibrating the position of the first cutting wheel or other components is omitted, and the silicon rod can be cut according to the preset cutting amount, so that the groove changing process is simplified.

[0086] To further illustrate the implementation method of at least one first distance adjustment mechanism to move multiple first cutting wheels in the first wire cutting unit in a direction perpendicular to the wheel surface of the first cutting wheel, the present application discloses the following embodiments. When the number of first wire cutting units in the first silicon rod cutting device is different, the specific form of the at least one first distance adjustment mechanism can be changed accordingly.

[0087] In some embodiments, the first silicon rod cutting device includes a single-wire cutting unit, and the single-wire cutting unit is a first wire cutting unit. The first distance adjustment mechanism includes: a screw, which is arranged along the orthogonal direction of the first cutting wheel surface and is threadedly connected to the single-wire cutting unit; and a screw driving source, which is used to drive the screw to rotate.

[0088] The single-wire cutting unit in the first silicon rod cutting device includes a plurality of first cutting wheels, and the first cutting wire is wound around the plurality of first cutting wheels to form at least one first cutting wire saw. The screw of the first distance adjustment mechanism has a distal end and a proximal end. In a specific implementation, for example, the proximal end of the screw can be connected to a screw drive source and rotated under the drive of the screw drive source, and the distal end of the screw is connected to the first single-wire cutting unit by a thread. Through the connection method at both ends of the screw, the screw can rotate based on the transmission of the screw drive source and convert the screw rotation into axial displacement by means of the threaded connection. The axial displacement direction is the setting direction of the screw, that is, the orthogonal direction of the cutting wheel surface; the displacement of the single-wire cutting unit in the orthogonal direction of the first cutting wheel surface can be achieved by driving the screw drive source in the first distance adjustment mechanism to rotate. The first cutting wheel of the single-wire cutting unit can be moved forward or backward in the orthogonal direction of the first cutting wheel surface by driving the screw to rotate in different directions.

[0089] In some embodiments, the first silicon rod cutting device includes a single-wire cutting unit, and here, the single-wire cutting unit is a first wire cutting unit. The first distance adjustment mechanism includes: a telescopic member, which is arranged along the orthogonal direction of the first cutting wheel surface and is associated with the single-wire cutting unit; a telescopic member driving source, which is used to drive the telescopic member to perform telescopic movement along the orthogonal direction of the first cutting wheel surface. Here, the telescopic member can be set as a rod body structure and the extension direction of the rod body is the orthogonal direction of the first cutting wheel surface. The telescopic member can be telescopically moved along its extension direction under the drive of the telescopic member driving source. One end of the telescopic member can be connected to the telescopic member driving source, and the retractable free end is associated with the single-wire cutting unit, that is, the first cutting wheel of the single-wire cutting unit can be driven to move in the orthogonal direction of the first cutting wheel surface under the action of the telescopic member driving source. The telescopic member is, for example, an electric telescopic rod, or a connecting rod connected to a cylinder. The cylinder can be used as a telescopic member driving source, and this application does not limit it. The telescopic rod can be connected to the single-wire cutting unit in a linear connection or an indirect connection, for example, it can be directly connected to the first cutting mounting structure of the single-wire cutting unit, or indirectly connected to the first single-wire cutting unit through a support or a bearing. It should be understood that the extension or contraction of the telescopic member can correspond to the advancement or retreat of the single-wire cutting unit along the orthogonal direction of the first cutting wheel surface.

[0090] Here, in some embodiments, the association can be achieved by one or more of snap-fit, screw-locking, bonding, and welding. For example, in the above embodiments, the telescopic rod can be associated with the first wire cutting unit by one or more of snap-fit, screw-locking, bonding, and welding; of course, the implementation method of the association is not limited to this, but is intended to achieve transmission in the second direction.

[0091] In some embodiments, the first silicon rod cutting device includes a single-wire cutting unit, and the single-wire cutting unit is a wire cutting unit. The first distance adjustment mechanism includes: a rack, which is arranged on the first single-wire cutting unit along the orthogonal direction of the first cutting wheel surface; a transmission gear, which is meshed with the rack; and a gear driving source, which is used to drive the transmission gear to rotate. The transmission gear rotates under the drive of the gear driving source, and the rack meshed with the transmission gear moves accordingly along the step direction of the rack. In this example, the rotational motion driven by the gear driving source can be converted into a wire transport along the direction of the rack by cooperating with the transmission gear. The rack is arranged on the first single-wire cutting unit along the orthogonal direction of the first cutting wheel surface, which can drive the first cutting wheel of the single-wire cutting unit to move along the orthogonal direction of the first cutting wheel surface. At the same time, the gear driving source controls the switching of the rotation direction of the transmission gear, so that the multiple first cutting wheels of the single-wire cutting unit can move forward or backward along the orthogonal direction of the first cutting wheel surface.

[0092] In certain embodiments, such as Figure 5As shown, the first silicon rod cutting device includes two first wire cutting units arranged in parallel and opposite to each other, and at least one of the two first wire cutting units can be driven to move along the orthogonal direction of the first cutting wheel surface by at least one distance adjustment mechanism, so as to adjust the wire cutting wire saw spacing between the first cutting wire saws in the two first wire cutting units, or change the first cutting wire winding around the cutting wire grooves of multiple first cutting wheels in a certain first wire cutting unit.

[0093] At least one first distance adjustment mechanism can be configured to be connected to a first wire cutting unit, or to be associated with two first wire cutting units at the same time, so as to drive multiple first cutting wheels in the connected or associated one or two first wire cutting units to move along the orthogonal direction of the first cutting wheel surface.

[0094] In certain embodiments, the first distance adjusting mechanism includes: a screw, which is arranged along the orthogonal direction of the first cutting wheel surface and is threadedly connected to a first wire cutting unit; and a screw driving source for driving the screw to rotate. The manner in which the multiple first cutting wheels in the first wire cutting unit to which the screw is driven and connected to the screw driving source move in the orthogonal direction of the first cutting wheel surface is similar to the aforementioned embodiment. The first cutting unit driven by the distance adjusting mechanism can be regarded as a single-wire cutting unit, which will not be described in detail here. It should be understood that by providing a first distance adjusting mechanism on any first wire cutting unit, the spacing between the parallel first cutting wire saws formed between the two first wire cutting units can be increased or decreased, and the first silicon rod cutting device can cut the silicon rods into different specifications.

[0095] In some embodiments, the first distance adjustment mechanism includes: a telescopic member, which is arranged along the orthogonal direction of the first cutting wheel surface and is associated with a first wire cutting unit; and a telescopic member driving source, which is used to drive the telescopic member to perform telescopic movement along the orthogonal direction of the first cutting wheel surface. Here, the first cutting unit provided with the first distance adjustment mechanism can be regarded as a single wire cutting unit, and the specific implementation method can refer to the above embodiment, which will not be repeated here.

[0096] In some embodiments, the first spacing mechanism includes: a spacing rack, which is along the orthogonal direction of the first cutting wheel surface and is associated with a first linear cutting unit; a transmission gear, which is meshed with the spacing rack; and a gear driving source, which is used to drive the transmission gear to rotate. Through the meshing transmission gear and the spacing rack, the gear driving source can control the spacing rack to move along the rack direction line, and the first linear cutting unit associated with the spacing rack can drive multiple first cutting wheels to move along the orthogonal direction of the first cutting wheel surface through the rack.

[0097] In some embodiments, the distance adjustment mechanism includes: a bidirectional screw, which is arranged along the orthogonal direction of the first cutting wheel surface and is threadedly connected to the two first wire cutting units; and a screw drive source, which is used to drive the screw to rotate so that the two first wire cutting units move toward or away from each other along the orthogonal direction of the first cutting wheel surface. In one embodiment, the bidirectional screw is a double-threaded screw, and the two ends of the bidirectional screw are respectively provided with threads and the thread directions are opposite. The screw drive source can be set at either end of the bidirectional screw to drive the bidirectional screw to rotate along the screw shaft. Through the threads with opposite directions at both ends of the bidirectional screw, when the bidirectional screw rotates under the drive of the screw drive source, the movement of the two ends of the bidirectional screw is converted into axial linear motion in opposite directions. The axial direction is the orthogonal direction of the first cutting wheel surface where the bidirectional screw is set. Driven by the screw drive source, the multiple first cutting wheels corresponding to the two first wire cutting units can move toward or away from each other.

[0098] In some embodiments, the first distance adjustment mechanism includes a servo motor provided on at least one first wire cutting unit. In actual scenarios, a servo motor is provided on at least one first wire cutting unit or each first wire cutting unit of the first silicon rod cutting device, and the servo motor controls the displacement of the corresponding first wire cutting unit in the orthogonal direction of the first cutting wheel surface. The first wire cutting unit can predetermine the cutting offset of the slot change or the adjustment amount of the cutting line change cutting position, and drive the multiple first cutting wheels in the first wire cutting unit to move along the orthogonal direction of the first cutting wheel surface with a preset displacement through the precise positioning function of the servo motor. For example, two first wire cutting units are provided in the first silicon rod cutting device, and at least one of the two first wire cutting units moves relatively independently along the orthogonal direction of the first cutting wheel surface under the drive of its corresponding servo motor. In some examples, the servo motor can also be replaced with a travel motor and a travel screw. It should be understood that the first distance adjustment mechanism is a driving device for driving the multiple first cutting wheels in the first wire cutting unit to move relative to each other, and its specific form is not limited in this application.

[0099] As mentioned above, in the first silicon rod cutting device, the first cutting wire saws of the two first wire cutting units arranged in parallel are arranged along the vertical direction or at an angle to the vertical direction, driving the first silicon rod transfer device and the silicon rod carried by it to move along the transfer direction, and the first wire cutting unit and the first silicon rod transfer device move relatively along the transfer direction, and the first cutting wire saws in the two first wire cutting units perform the first cutting operation on the silicon rod carried by the first silicon rod transfer device. The first wire cutting unit is used to cut the silicon rod to be cut, so that the silicon rod forms a cutting surface and a side skin, that is, the silicon rod is cut by a cutting wire saw in a first wire cutting unit, so that the silicon rod forms a cutting surface and leaves a side skin. Therefore, the first cutting wire saws in the two first wire cutting units arranged in parallel in the first silicon rod cutting device perform the first cutting operation on the silicon rod with a circular cross section, so that the silicon rod forms two parallel first side cut surfaces.

[0100] The half-rod cutting device comprises a first edge skin anti-collapse device cooperating with the first silicon rod transfer device, which is used to stabilize the edge skin when the first silicon rod cutting device performs the first cutting operation on the silicon rod.

[0101] It should be understood that the silicon rods carried by the first silicon rod transfer device are horizontal, that is, the axis of the silicon rods is consistent with the transfer direction (i.e., the first direction X axis). Therefore, the edge skin formed by the first silicon rod cutting device performing the first cutting operation on the silicon rods is also horizontal.

[0102] In some embodiments, the first edge skin collapse prevention device includes a clamping support and an edge skin clamp, wherein the edge skin clamp is arranged on the clamping support and is used to clamp the edge skin.

[0103] The edge skin clamp comprises: a clamp seat, at least a pair of end face clamps, and a clamp driving mechanism.

[0104] At least one pair of end face clamps are arranged opposite to each other along the transfer direction and are used for clamping two end faces of the silicon rod.

[0105] The first silicon rod transfer device includes a first edge skin anti-collapse device, which cooperates with the first silicon rod transfer device and is used to clamp the end face of the silicon rod during the first cutting operation to prevent edge collapse.

[0106] In some embodiments, the first edge skin anti-collapse device comprises: a clamping support and an edge skin clamp. Figure 5 and Figure 6 In the illustrated embodiment, the first edge skin anti-collapse device 16 includes a clamping support 161 and an edge skin clamp 162 .

[0107] In some embodiments, the clamping support of the first edge skin anti-collapse device is associated with the first supporting platform of the first silicon rod transfer device, that is, the clamping support of the first edge skin anti-collapse device and the first supporting platform of the first silicon rod transfer device can move forward and backward together.

[0108] The edge skin clamp is arranged on the clamping support. In some embodiments, the edge skin clamp includes a clamping seat, at least one pair of end face clamps, and a clamp driving mechanism. Figure 6 In the illustrated embodiment, the edge skin clamp 162 includes a clamp seat 1621, a pair of end face clamps 1622 arranged opposite to each other along the clamping direction, and a clamp driving mechanism.

[0109] The chuck driving mechanism is used to drive at least one end face chuck of at least one pair of end face chucks to move along the clamping direction to adjust the clamping distance between the at least one pair of end face chucks.

[0110] In some embodiments, the chuck driving mechanism includes: a chuck moving guide rail arranged along the clamping direction; and a chuck driving unit for driving at least one end face chuck of at least one pair of end face chucks to move along the chuck moving guide rail.

[0111] In some embodiments, a chuck moving guide rail may be provided between the first end face chuck and the second end face chuck in at least one pair of end face chucks. Figure 6 As shown, a movable guide assembly is provided between the first end face chuck and the second end face chuck in at least one pair of end face chucks, and the movable guide assembly includes one or more movable guide rods or movable guide beams 1623, and a movable guide rail is provided on the movable guide rods or movable guide beams 1623.

[0112] In some embodiments, the chuck drive unit includes at least one chuck telescoping assembly. Figure 6As shown, the chuck telescopic assembly includes: a chuck telescopic rod and a chuck telescopic cylinder, the chuck telescopic rod is arranged along the clamping direction and is associated with a corresponding end face chuck, and the chuck telescopic cylinder is associated with the chuck telescopic rod. In some embodiments, the chuck driving mechanism is used to drive two end face chucks in a pair of end face chucks to move toward or away from each other along the clamping direction, and the chuck driving mechanism includes a pair of chuck telescopic assemblies, wherein each chuck telescopic assembly corresponds to an end face chuck, the chuck telescopic rod in the chuck telescopic assembly is arranged along the clamping direction and is associated with a corresponding end face chuck, and the chuck telescopic cylinder in the chuck telescopic assembly is associated with the chuck telescopic rod. By using the chuck telescopic cylinders in a pair of chuck telescopic assemblies to control the corresponding chuck telescopic rod to retract or extend, a pair of end face chucks can be driven to move toward or away from each other along the movable guide rails on the movable guide rod or movable guide beam. In certain embodiments, the chuck driving mechanism is used to drive one end face chuck of a pair of end face chucks to move toward or away from the other end face chuck along the clamping direction, and the chuck driving mechanism includes a chuck telescopic assembly corresponding to the end face chuck to be moved, wherein the chuck telescopic rod in the chuck telescopic assembly is arranged along the clamping direction and associated with the corresponding end face chuck, and the chuck telescopic cylinder in the chuck telescopic assembly is associated with the chuck telescopic rod. The chuck telescopic cylinder in the chuck telescopic assembly is used to control the corresponding chuck telescopic rod to retract or extend, so that the corresponding end face chuck can be driven to move along the movable guide rail on the movable guide rod or movable guide beam toward or away from the other end face chuck.

[0113] In some embodiments, the chuck driving unit includes: at least one pair of clamping racks, a driving gear, and a gear driving source. The at least one pair of clamping racks are respectively associated with the at least one pair of end face chucks, that is, the first clamping rack of the at least one pair of clamping racks is arranged along the clamping direction and is associated with the first end face chuck of the at least one pair of end face chucks, the second clamping rack of the at least one pair of clamping racks is arranged along the clamping direction and is associated with the second end face chuck of the at least one pair of end face chucks, and the first clamping rack and the second clamping rack of the at least one pair of clamping racks are arranged in a manner that the teeth are opposite to each other. The driving gear is meshed with the pair of clamping racks, that is, the driving gear is located between the first clamping rack and the second clamping rack of the pair of clamping racks and is respectively meshed with the first clamping rack and the second clamping rack. The gear driving source is used to drive the driving gear to rotate so that at least one pair of meshing clamping racks drives at least one pair of associated end face chucks to move toward or away from each other along the clamping direction, wherein the gear driving source may be, for example, a servo motor, and the output shaft of the servo motor is associated with the driving gear. In practical applications, the servo motor as the gear driving source rotates forward, driving the associated driving gear to rotate forward, so that the first clamping rack meshing with the driving gear and the second clamping rack are moved toward each other, that is, the first end face chuck associated with the first clamping rack and the second end face chuck associated with the second clamping rack are moved toward each other, and the clamping distance between the first end face chuck and the second end face chuck is reduced. The servo motor as the gear driving source rotates reversely, driving the associated driving gear to rotate reversely, so that the first clamping rack meshing with the driving gear and the second clamping rack are moved away from each other, that is, the first end face chuck associated with the first clamping rack and the second end face chuck associated with the second clamping rack are moved away from each other, and the clamping distance between the first end face chuck and the second end face chuck is increased.

[0114] In some embodiments, the chuck driving unit includes: at least one pair of clamping racks, a linkage gear, and a chuck driving source. The at least one pair of clamping racks are respectively associated with the at least one pair of end face chucks, that is, the first clamping rack of the at least one pair of clamping racks is arranged along the clamping direction and is associated with the first end face chuck of the at least one pair of end face chucks, the second clamping rack of the at least one pair of clamping racks is arranged along the clamping direction and is associated with the second end face chuck of the at least one pair of end face chucks, and the first clamping rack and the second clamping rack of the at least one pair of clamping racks are arranged in a manner that the teeth are opposite to each other. The linkage gear is meshed with the pair of clamping racks, that is, the linkage gear is located between the first clamping rack and the second clamping rack of the pair of clamping racks and is respectively meshed with the first clamping rack and the second clamping rack. The chuck driving source is associated with at least one pair of end face chucks, and is used to cooperate with at least one pair of clamping racks and linkage gears to drive at least one pair of end face chucks to move toward or away from each other along the clamping direction, wherein the chuck driving source can be, for example, a telescopic cylinder, and the two ends of the telescopic cylinder are respectively connected to the first end face chuck and the second end face chuck. In practical applications, the telescopic cylinder as the chuck driving source contracts, and the contracted cylinder can drive the first clamping rack or the second clamping rack to move, and through the first clamping rack, the second clamping rack and the linkage gear between the first clamping rack and the second clamping rack, the associated first end face chuck and the second end face chuck are driven to move toward each other, thereby reducing the clamping distance between the first end face chuck and the second end face chuck. The telescopic cylinder serving as the driving source of the chuck is extended, and the extended cylinder can drive the first clamping rack or the second clamping rack to move, and through the first clamping rack, the second clamping rack and the linkage gear between the first clamping rack and the second clamping rack, the associated first end face chuck and the second end face chuck are driven to move away from each other, thereby increasing the clamping distance between the first end face chuck and the second end face chuck.

[0115] In some embodiments, the chuck driving unit includes: at least one chuck clamping assembly, the chuck clamping assembly includes: a clamping screw and a screw driving source, the clamping screw is arranged along the clamping direction and is associated with a corresponding end face chuck, and the screw driving source is associated with the clamping screw. In some embodiments, the chuck driving mechanism is used to drive two end face chucks in a pair of end face chucks to move toward or away from each other along the clamping direction, and the chuck driving mechanism includes a pair of chuck clamping assemblies, wherein each chuck clamping assembly corresponds to an end face chuck, the clamping screw in the chuck clamping assembly is arranged along the clamping direction and is associated with a corresponding end face chuck, and the screw driving source in the chuck clamping assembly is associated with the clamping screw. In some embodiments, the chuck driving mechanism is used to drive one end face chuck of a pair of end face chucks to move toward or away from the other end face chuck along the clamping direction, and the chuck driving mechanism includes a chuck clamping assembly corresponding to the end face chuck to be moved, wherein the clamping screw in the chuck clamping assembly is arranged along the clamping direction and associated with the corresponding end face chuck, and the screw driving source in the chuck clamping assembly is associated with the clamping screw. The screw driving source can be, for example, a servo motor.

[0116] In some embodiments, the chuck driving unit includes: a bidirectional screw and a screw driving source, wherein the bidirectional screw is arranged along the clamping direction, two ends of the bidirectional screw are respectively provided with threads and the thread directions are opposite, the two ends of the bidirectional screw are respectively associated with at least one pair of end face chucks, and the screw driving source is associated with the bidirectional screw. In practical applications, the bidirectional screw is driven to rotate by the screw driving source (such as a servo motor) so that the two associated opposite end face chucks move toward or away from each other along the clamping direction.

[0117] At least one pair of end face clamps are arranged opposite to each other along the clamping direction, and are used for correspondingly clamping the two end faces of the silicon rod.

[0118] In some embodiments, for any one of at least a pair of end face chucks, the end face chuck includes a clamping base and a side skin pressing piece provided on the clamping base, and the side skin pressing piece is used to press the side skin to be cut in the silicon rod.

[0119] The clamping base serves as the main body of the end face chuck and is used to provide a foundation for the edge skin pressing piece. In some embodiments, the clamping base may be, for example, a clamping substrate whose size is adapted to the edge skin to be cut, that is, the clamping substrate at least partially or completely covers the edge skin to be cut.

[0120] In the end face chuck, the edge skin pressing member includes an edge skin pressing screw provided on the clamping base plate, and the number of the edge skin pressing screws can be one or more. In practical applications, the edge skin pressing screw is used to press the edge skin to be cut, so as to ensure that the edge skin to be cut in the silicon rod remains stable during the first cutting operation.

[0121] Of course, in some embodiments, in the end face chuck, the edge skin pressing member may also include an edge skin pressing elastic member disposed on the clamping base. For example, in some embodiments, the edge skin pressing elastic member includes an edge skin pushing rod, which is sleeved with a compression spring.

[0122] In this way, when the first silicon rod cutting device is used to perform the first cutting operation on the silicon rod, the first silicon rod transfer device carries the silicon rod to be cut, and the chuck driving mechanism in the first edge skin collapse prevention device drives at least one end face chuck of at least one pair of end face chucks to move along the clamping direction, so that at least one pair of end face chucks clamps the two end faces of the silicon rod, wherein the edge skin pressing piece in the end face chuck presses on the edge skin to be cut in the silicon rod, which can ensure that the edge skin to be cut in the silicon rod remains stable during the first cutting operation, and can avoid the edge skin falling off or the edge skin and the silicon rod body being offset to cause edge collapse when the first cutting wire saw in the first wire cutting unit penetrates the silicon rod to completely cut it off.

[0123] In an embodiment, for any one of at least one pair of end face chucks, the end face chuck includes a silicon rod pressing piece, a side skin pressing piece and a side skin clamping reinforcement piece, wherein the silicon rod pressing piece is used to press the main body of the silicon rod, the side skin pressing piece is used to press the side skin to be cut in the silicon rod, and the side skin clamping reinforcement piece is used to apply additional clamping force to the side skin. In the present application, a silicon rod with a circular cross-section is formed into a square silicon rod with a rectangular cross-section after a square cutting operation, wherein the main body of the silicon rod refers to a portion that at least includes the square silicon rod, that is, the main body of the silicon rod is relative to the side skin, the main body of the silicon rod is the portion that includes the square silicon rod, and the main body of the silicon rod changes in different square cutting operations. In the following description, the main body of the silicon rod is referred to as the silicon rod main body.

[0124] See also Figure 7 , displayed as Figure 6 A schematic diagram of the structure of the middle edge skin clamp in one embodiment. Figure 6 and Figure 7 In the illustrated embodiment, the end face chuck includes a clamping base 1624, a silicon rod pressing member 1625 and a side skin pressing member 1626 provided on the clamping base 1624, and a side skin clamping reinforcement member 1627 which moves forward and backward along the clamping direction relative to the clamping base 1624.

[0125] The clamping base 1624 serves as the main body of the end face chuck, and is used to provide a foundation for the silicon rod pressing piece 1625, the edge skin pressing piece 1626, and the edge skin clamping reinforcement piece 1627. In some embodiments, the clamping base may be, for example, a clamping substrate, the size of which is adapted to the end face of the silicon rod and the edge skin to be cut, that is, the clamping substrate at least covers part of the silicon rod body and part of the edge skin. The clamping substrate should cover part of the silicon rod body so that the silicon rod pressing piece arranged thereon can act on the silicon rod body. The clamping substrate should also cover part of the edge skin so that the edge skin pressing piece and the edge skin clamping reinforcement piece arranged thereon can act on the edge skin.

[0126] In such Figure 7 In the illustrated embodiment, in the end face chuck, the silicon rod pressing member 1625 includes a silicon rod pressing screw disposed on the clamping substrate 1624, and the edge skin pressing member 1626 includes an edge skin pressing screw disposed on the clamping substrate 1624. The number of silicon rod pressing screws may be one or more, and the number of edge skin pressing screws may be one or more. In practical applications, the silicon rod pressing screw is used to press the main body of the silicon rod, and the edge skin pressing screw is used to press the edge skin to be cut. Under the condition that the silicon rod pressing screw presses the main body of the silicon rod and the edge skin pressing screw presses the edge skin to be cut, it can ensure that the main body of the silicon rod and the edge skin remain relatively stable, and it can be avoided that the edge skin falls off when the cutting wire saw in the wire cutting unit passes through the silicon rod to completely cut off, or the edge skin and the main body of the silicon rod are offset to cause edge collapse.

[0127] It is easy to know that in some cases, the end surface of the silicon rod is not an ideal flat surface, and it may happen that one of the silicon rod pressing piece and the side skin pressing piece cannot effectively resist and press the corresponding silicon rod body or side skin.

[0128] In order to make the silicon rod pressing piece and the side skin pressing piece arranged on the clamping base adapt to the end face of the silicon rod to achieve effective pressing, in some embodiments, the end face clamp also includes an offset fine-tuning structure for adjusting the position of the clamping base. The offset fine-tuning structure can be used to partially adjust the position of the clamping base, thereby changing the position of the silicon rod pressing piece and the side skin pressing piece arranged on the clamping base. Figure 7 In the illustrated embodiment, the end face chuck also includes an offset fine-tuning structure for adjusting the clamping substrate 1624. The offset fine-tuning structure can be used to partially adjust the position of the clamping substrate 1624, thereby changing the position of the silicon rod pressing screw and the side skin pressing screw arranged on the clamping substrate 1624.

[0129] In some embodiments, the offset fine-tuning structure adopts a ball head structure or a similar structure, and the clamping base is arranged by the ball head structure. Figure 7As shown, the clamping substrate 1624 as a clamping base is arranged on the mounting structure through a ball head structure 1629. In this way, the clamping substrate 1624 can be fine-tuned to a certain extent relative to the mounting structure through the ball head structure 1629, and the positions of the clamping substrate 1624 and the silicon rod pressing screws 1625 and the side skin pressing screws 1626 arranged thereon are changed, so as to adapt to the end face of the silicon rod, even if the end face of the silicon rod is uneven to a certain extent. In some embodiments, the ball head structure is a spherical steel ball, which is embedded in a storage cavity and exposes a small half of the contact with the clamping substrate. In some embodiments, the ball head or hemispherical head, the ball head or hemispherical head is connected to the clamping substrate through a connecting rod, and the ball head or hemispherical head is embedded in a storage cavity.

[0130] In some embodiments, the deflection fine-tuning structure adopts a hinge structure, and the clamping base is arranged by the hinge structure. For example, the clamping base is associated with the mounting structure by the hinge structure, and can deflect to a certain extent relative to the mounting structure.

[0131] In addition, in some embodiments, in the end face chuck, the silicon rod pressing member includes a silicon rod pressing elastic member provided on the clamping base, and the side skin pressing member includes a side skin pressing elastic member provided on the clamping base. For example, in some embodiments, the silicon rod pressing elastic member includes a silicon rod push rod, which is sleeved with a compression spring; the side skin pressing elastic member includes a side skin push rod, which is sleeved with a compression spring. In some embodiments, the silicon rod pressing elastic member includes a silicon rod push block, whose rear end is provided with a compression spring; the side skin pressing elastic member includes a side skin push block, whose rear end is provided with a compression spring.

[0132] The end face chuck also includes a side skin clamping reinforcement member, which can move forward and backward relative to the clamping base along the clamping direction. When the side skin clamping reinforcement member moves forward relative to the clamping base, the side skin clamping reinforcement member can provide a strong clamping force on the corresponding side skin. Generally, the clamping force applied by the side skin clamping reinforcement member on the side skin is greater than the top pressure applied by the silicon rod pressing member on the silicon rod body and the top pressure applied by the side skin pressing member on the side skin.

[0133] In some embodiments, the edge skin clamping reinforcement member includes a telescopic top rod or a telescopic top block that is controlled to move forward and backward relative to the clamping base. Figure 7In the illustrated embodiment, the edge skin clamping reinforcement member includes a telescopic top rod or a telescopic top block 1627 and a telescopic driving source 1628, and the telescopic driving source 1628 drives the telescopic top rod or the telescopic top block 1627 to move forward and backward relative to the clamping base plate 1624. In some embodiments, a through hole is provided on the clamping base plate 1624, and the telescopic driving source 1628 and the telescopic top rod or the telescopic top block 1627 are arranged on the mounting structure, and the telescopic driving source 1628 can drive the telescopic top rod or the telescopic top block 1627 to extend out of the clamping base plate 1624 and press against the corresponding edge skin, or drive the telescopic top rod or the telescopic top block 1627 to retract into the clamping base plate 1624. The telescopic driving source can be, for example, a telescopic cylinder.

[0134] The end face chuck can still be changed in other embodiments. In some embodiments, the end face chuck includes: a first clamping base and a second clamping base, wherein a silicon rod pressing piece is arranged on the first clamping base, and a side skin pressing piece and a side skin clamping reinforcement piece that moves forward and backward relative to the second clamping base along the clamping direction are arranged on the second clamping base.

[0135] In some embodiments, the first clamping substrate may be, for example, a clamping substrate, whose size is adapted to the end face of the silicon rod body, that is, the first clamping substrate at least covers a portion of the silicon rod body, so that the silicon rod pressing piece disposed thereon can act on the silicon rod body. The second clamping substrate may be, for example, a clamping substrate, whose size is adapted to the end face of the edge skin to be cut, that is, the first clamping substrate at least covers a portion of the edge skin, so that the edge skin pressing piece disposed thereon can act on the edge skin.

[0136] In the end face chuck, the silicon rod pressing member includes a silicon rod pressing screw provided on the first clamping substrate, and the number of the silicon rod pressing screws can be one or more. The edge skin pressing member includes an edge skin pressing screw provided on the second clamping substrate, and the number of the edge skin pressing screws can be one or more. In practical applications, the silicon rod pressing screw is used to press the silicon rod body, and the edge skin pressing screw is used to press the edge skin to be cut. Under the condition that the silicon rod pressing screw presses the silicon rod body and the edge skin pressing screw presses the edge skin to be cut, it can ensure that the silicon rod body and the edge skin remain relatively stable, and it can be avoided that the edge skin falls off when the cutting wire saw in the wire cutting unit passes through the silicon rod to completely cut off, or the edge skin and the silicon rod body are offset to cause edge collapse.

[0137] In addition, in some embodiments, in the end face chuck, the silicon rod pressing member includes a silicon rod pressing elastic member provided on the first clamping base, and the side skin pressing member includes a side skin pressing elastic member provided on the second clamping base. For example, in some embodiments, the silicon rod pressing elastic member includes a silicon rod push rod, which is sleeved with a compression spring; the side skin pressing elastic member includes a side skin push rod, which is sleeved with a compression spring. In some embodiments, the silicon rod pressing elastic member includes a silicon rod push block, whose rear end is provided with a compression spring; the side skin pressing elastic member includes a side skin push block, whose rear end is provided with a compression spring.

[0138] The end face chuck also includes a side skin clamping reinforcement member, which can move forward and backward relative to the second clamping base along the clamping direction. When the side skin clamping reinforcement member moves forward relative to the second clamping base, the side skin clamping reinforcement member can provide a strong clamping force on the corresponding side skin. Generally, the clamping force applied by the side skin clamping reinforcement member to the side skin is greater than the top pressure applied by the silicon rod pressing member to the silicon rod body and the top pressure applied by the side skin pressing member to the side skin.

[0139] In some embodiments, the side skin clamping reinforcement includes a telescopic top rod or a telescopic top block that is controlled to advance and retreat relative to the second clamping base. For example, the side skin clamping reinforcement includes a telescopic top rod or a telescopic top block and a telescopic driving source, and the telescopic driving source drives the telescopic top rod or the telescopic top block to advance and retreat relative to the second clamping base. In some embodiments, a through hole is provided on the second clamping base, and the telescopic driving source and the telescopic top rod or the telescopic top block are arranged on a mounting structure. The telescopic driving source can drive the telescopic top rod or the telescopic top block to extend out of the second clamping base and press against the corresponding side skin, or drive the telescopic top rod or the telescopic top block to retract into the second clamping base. Among them, the telescopic driving source can be, for example, a telescopic cylinder.

[0140] In this way, when the first silicon rod cutting device is used to perform the first cutting operation on the silicon rod, the first silicon rod transfer device carries the silicon rod to be cut, and the clamp driving mechanism in the first edge skin collapse prevention device drives at least one end face clamp of at least one pair of end face clamps to move along the clamping direction, so that at least one pair of end face clamps clamps the two end faces of the silicon rod, wherein the silicon rod pressing piece in the end face clamp presses on the main body of the silicon rod, and the edge skin pressing piece in the end face clamp presses on the edge skin to be cut in the silicon rod, and the end face clamp The edge skin clamping reinforcement is in a retracted state (in the retracted state, the edge skin clamping reinforcement is recessed in the clamping base, or protrudes from the clamping base but the protrusion height relative to the clamping base is also smaller than the protrusion height of the silicon rod pressing piece and the edge skin pressing piece relative to the clamping base), so that the edge skin and the silicon rod body remain relatively still, which can prevent the edge skin from falling off or the edge skin and the silicon rod body from shifting and causing edge collapse when the cutting wire saw in the wire cutting unit passes through the silicon rod to be cut to completely cut it off. After the edge skin is cut, the edge skin clamping reinforcement in the driving end face chuck extends relative to the clamping base and presses against the cut edge skin. The clamping force applied by the edge skin clamping reinforcement on the edge skin is greater than the pressing force applied by the silicon rod pressing piece on the silicon rod body and the pressing force applied by the edge skin pressing piece on the edge skin. At this time, at least one pair of end face chucks can be operated to move the cut edge skin.

[0141] In the present application, the first edge skin collapse prevention device may further include an edge skin clamp advance and retreat mechanism for driving the edge skin clamp to advance and retreat along an advance and retreat direction.

[0142] In an embodiment in which the end face chuck includes a clamping base and a side skin pressing piece arranged on the clamping base, after the side skin cutting is completed, the side skin clamp is driven to withdraw in the forward and backward direction by the side skin clamp advance and retreat mechanism, and the pressing pressure applied to the side skin by the pressing piece can drive the clamped side skin to separate from the silicon rod body.

[0143] In an embodiment in which the end face chuck includes a clamping base, a silicon rod pressing piece and a side skin pressing piece arranged on the clamping base, and a side skin clamping reinforcement piece which advances and retreats relative to the clamping base in a clamping direction, after the side skin cutting is completed, the side skin clamping reinforcement piece in the end face chuck is driven to extend relative to the clamping base and press against the cut side skin. At this time, the side skin clamp is driven to retreat in the advance and retreat direction by the side skin clamp advance and retreat mechanism. The clamping force applied by the side skin clamping reinforcement piece on the side skin is greater than the pressing force applied by the silicon rod pressing piece on the silicon rod body and the pressing force applied by the side skin pressing piece on the side skin, thereby driving the clamped side skin to separate from the silicon rod body.

[0144] In some embodiments, the edge skin clamp advance and retreat mechanism includes: a clamp advance and retreat guide rail, arranged along the advance and retreat direction; and an edge skin clamp advance and retreat unit, used to drive the edge skin clamp to move along the clamp advance and retreat guide rail. Figure 6In the illustrated embodiment, the edge skin clamp advance and retreat mechanism 163 includes: a clamp advance and retreat guide rail 1631 and an edge skin clamp advance and retreat unit.

[0145] In some embodiments, the edge skin clamp advance and retreat unit includes: a clamp seat telescopic rod and a clamp seat telescopic cylinder, the clamp seat telescopic rod is arranged along the advance and retreat direction and is associated with the clamp seat of the edge skin clamp, and the clamp seat telescopic cylinder is associated with the clamp seat telescopic rod. Figure 6 In the illustrated embodiment, the skin clamp advance and retreat unit includes: a clamp seat telescopic rod 1633 and a clamp seat telescopic cylinder 1635, wherein the clamp seat telescopic rod 1633 is arranged along the advance and retreat direction and is associated with the clamp seat 1621 of the skin clamp, and the clamp seat telescopic cylinder 1635 can be arranged on a mounting structure and is associated with the clamp seat telescopic rod 1633. In some embodiments, the clamp seat telescopic cylinder 1635 drives the clamp seat telescopic rod to extend, driving the skin clamp 162 to move toward the first silicon rod transfer device, so that the skin clamp 162 can clamp the end face of the silicon rod. In some embodiments, the clamp seat telescopic cylinder 1635 drives the clamp seat telescopic rod to contract, driving the skin clamp 162 to move away from the first silicon rod transfer device, so that the skin clamp 162 drives the clamped skin to withdraw to separate from the silicon rod body.

[0146] In some embodiments, the edge skin clamp advance and retreat unit includes: the edge skin clamp advance and retreat mechanism includes: a clamp seat rack, arranged along the advance and retreat direction and associated with the clamp seat of the edge skin clamp; a clamp seat gear, meshing with the clamp seat rack; a gear drive source, associated with the clamp seat gear, used to drive the clamp seat gear to rotate so that the meshed edge skin clamp moves along the advance and retreat direction. Wherein, the gear drive source can be, for example, a servo motor. In practical applications, the servo motor as the gear drive source rotates forward, driving the associated clamp seat gear to rotate forward, so that the edge skin clamp associated with the clamp seat gear moves toward the silicon rod transfer device on the meshed clamp seat rack, so that the edge skin clamp can clamp the silicon rod end face. Conversely, the servo motor as the gear drive source rotates in the reverse direction, driving the associated clamp seat gear to rotate in the reverse direction, so that the edge skin clamp associated with the clamp seat gear moves away from the silicon rod transfer device on the meshed clamp seat rack, so that the edge skin clamp drives the clamped edge skin to withdraw to separate from the silicon rod body.

[0147] In certain embodiments, the side skin clamp advance and retreat unit includes: a withdrawal screw and a screw drive source, wherein the withdrawal screw is arranged along the advance and retreat direction and is associated with the clamp seat of the side skin clamp, and the screw drive source is associated with the withdrawal screw. The screw drive source may be, for example, a servo motor. In practical applications, the servo motor serving as the screw drive source rotates forward to drive the withdrawal screw to rotate forward, so that the side skin clamp associated with the withdrawal screw moves toward the silicon rod transfer device, so that the side skin clamp can clamp the end face of the silicon rod. Conversely, the servo motor serving as the screw drive source rotates in the reverse direction to drive the withdrawal screw to rotate in the reverse direction, so that the side skin clamp associated with the withdrawal screw moves away from the silicon rod transfer device, so that the side skin clamp drives the clamped side skin to withdraw to separate from the silicon rod body.

[0148] In the present application, the first edge skin anti-collapse device may also include a clamp lifting mechanism for driving the edge skin clamp to move up and down in the vertical direction. In some embodiments, the edge skin clamp is moved up or down in the vertical direction by the clamp lifting mechanism to adapt to the size of the silicon rods carried by the silicon rod transfer. For example, if the size of the silicon rod to be cut is large, the edge skin clamp is driven to move up in the vertical direction by the clamp lifting mechanism, and if the size of the silicon rod to be cut is small, the edge skin clamp is driven to move down in the vertical direction by the clamp lifting mechanism.

[0149] In some embodiments, the fixture lifting mechanism includes: a fixture lifting rail and a fixture lifting unit, wherein the fixture lifting rail is arranged vertically. The fixture lifting unit is used to drive the edge skin fixture to move up and down along the fixture lifting rail. Figure 6 In the illustrated embodiment, the fixture lifting mechanism 164 includes a fixture lifting guide rail 1641 and a fixture lifting unit.

[0150] In some embodiments, the edge clamp lifting unit includes: a lifting screw and a screw drive source, the lifting screw is arranged vertically and associated with the clamp seat of the edge clamp, and the screw drive source is associated with the lifting screw. Figure 6 In the illustrated embodiment, the edge clamp lifting unit includes: a lifting screw 1643 and a screw drive source, wherein the lifting screw 1643 is arranged vertically and associated with the mounting structure of the clamp seat on which the edge skin clamp is provided, and the screw drive source is associated with the lifting screw 1643. The screw drive source may be, for example, a servo motor. In practical applications, the servo motor serving as the screw drive source rotates forward, driving the lifting screw to rotate forward, so that the edge skin clamp associated with the lifting screw moves upward. Conversely, the servo motor serving as the screw drive source rotates reversely, driving the lifting screw to rotate reversely, so that the edge skin clamp associated with the lifting screw moves downward.

[0151] In certain embodiments, the clamp lifting unit includes: a lifting rack, a lifting gear, and a gear driving source, wherein the lifting rack is arranged vertically and associated with the clamp seat of the side skin clamp, the lifting gear is meshed with the lifting rack, and the gear driving source is associated with the lifting gear, and is used to drive the lifting gear to rotate so that the meshed side skin clamp is lifted and lowered vertically. The gear driving source may be, for example, a servo motor. In practical applications, the servo motor as the gear driving source rotates forward, driving the associated lifting gear to rotate forward, so that the side skin clamp associated with the clamp seat gear moves upward on the meshed clamp seat rack. Conversely, the servo motor as the gear driving source rotates reversely, driving the associated clamp seat gear to rotate reversely, so that the side skin clamp associated with the clamp seat gear moves downward on the meshed clamp seat rack.

[0152] So, when applying Figure 6 When the first edge skin anti-collapse device 16 is shown, the silicon rod is placed horizontally on the silicon rod carrying platform of the silicon rod transfer device; the edge skin clamp 162 is driven by the clamp lifting mechanism 164 in the first edge skin anti-collapse device 16 to move up and down vertically to adjust the position; the edge skin clamp advance and retreat mechanism 163 in the first edge skin anti-collapse device 16 drives the edge skin clamp to advance in the advance and retreat direction and approach the silicon rod; the clamp driving mechanism 162 in the first edge skin anti-collapse device 16 drives at least one of the at least one pair of end face clamps to move in the clamping direction until the silicon rod pressing piece on the end face clamp presses against the silicon rod body and the edge skin pressing piece on the end face clamp presses against the edge skin to be cut (for details, see Figure 8 Afterwards, the silicon rod cutting device performs a square cutting operation on the silicon rod to form a silicon rod body and a side skin (for details, see Fig. 9 After the edge skin 101 is cut, the edge skin clamping reinforcement member in the driving end face chuck extends relative to the clamping base and presses against the cut edge skin 101. At this time, the edge skin clamp 162 is driven to withdraw along the advance and retreat direction by the edge skin clamp advance and retreat mechanism 163. The clamping force applied by the edge skin clamping reinforcement member to the edge skin is greater than the pressure applied by the silicon rod pressing member to the silicon rod body and the pressure applied by the edge skin pressing member to the edge skin, thereby driving the clamped edge skin 101 to separate from the silicon rod body (for details, see Fig.10 The status diagram shown).

[0153] In the present application, the first edge skin collapse prevention device also includes an edge skin unloading and conveying mechanism, which is connected to the edge skin clamp advance and retreat mechanism.

[0154] In some embodiments, the edge skin unloading conveying mechanism may include an edge skin bearing structure and a conveying drive mechanism. Figure 5 As shown, the edge skin unloading mechanism may include an edge skin supporting structure 167 and a conveying drive mechanism 168.

[0155] The edge skin bearing structure 167 is used to bear the edge skin. As mentioned above, the edge skin clamped by the edge skin clamp is withdrawn in the forward and backward direction by using the edge skin clamp advance and retreat mechanism to drive the edge skin to separate from the silicon rod body, and then the chuck driving mechanism in the edge skin clamp drives the chuck to move to release the clamped edge skin and make it fall on the edge skin bearing structure. In some embodiments, the edge skin bearing structure can be, for example, an edge skin placement groove. The edge skin placement groove can be, for example, a U-shaped structure.

[0156] In some embodiments, the conveyor drive mechanism is used to drive the edge skin bearing structure to move along the transfer direction to move between the first loading and unloading position and the first cutting position. Figure 5 In the illustrated embodiment, the edge skin unloading mechanism device includes two edge skin bearing structures 167 and a conveying drive mechanism 168, and the conveying drive mechanism 168 is associated with the two edge skin bearing structures 167, and is used to drive the two edge skin bearing structures 167 to move between the first loading and unloading area and the first cutting area. In some embodiments, the conveying drive mechanism 168 can be, for example, a chain conveying mechanism. Of course, in the edge skin unloading conveying mechanism, a conveying drive mechanism can be configured for each edge skin bearing device, and the conveying drive mechanism drives the corresponding edge skin bearing structure. Taking the conveying drive mechanism as a chain conveying mechanism as an example, it includes a ring chain, a chain driving source, and a connecting piece, wherein the ring chain is a closed-loop chain, which is wound around multiple movable gears to form a preset shape, for example, an inverted triangle, a rectangle, or a trapezoid, etc. The side skin bearing structure is connected to the ring chain through a connecting piece, and the chain driving source can be, for example, a servo motor, and the servo motor is associated with one of the movable gears. For example, the output shaft of the servo motor is connected to the gear shaft of the movable gear. When the ring chain is driven by the servo motor, the side skin bearing structure and the side skin it carries can be driven to move in the transfer direction through the connecting piece. In actual applications, the servo motor works to drive the associated movable gear to rotate forward (or reversely), and the movable gear that rotates forward (or reversely) drives the meshing circular chain to move forward (or reversely), and the circular chain that moves forward (or reversely) can drive the side skin bearing structure to move from the first loading and unloading position to the first cutting position through the connecting piece; conversely, the servo motor works to drive the associated movable gear to rotate reversely (or forwardly), and the movable gear that rotates reversely (or forwardly) drives the meshing circular chain to move reversely (or forwardly), and the circular chain that moves reversely (or forwardly) can drive the side skin bearing structure and the side skin it carries from the first cutting position to the first loading and unloading position through the connecting piece.

The ejector member may be, for example, a lever or a bump.

[0158] In the present application, the edge skin unloading and conveying mechanism also includes an edge skin flipping mechanism, which is used to drive the edge skin bearing structure to flip.

In practical applications, the telescopic cylinder 1692 drives the telescopic rod 1691 to perform a contraction action, and the telescopic rod 1691 pulls the side skin bearing structure 167 to flip vertically through the pivot axis and be arranged vertically; the telescopic cylinder 1692 drives the telescopic rod 1691 to perform an extension action, and the telescopic rod 1691 pushes the side skin bearing structure 167 to flip vertically away from the pivot axis and be arranged flat or obliquely, so that the side skin carried by the side skin bearing structure 167 is lying flat or obliquely, so as to facilitate the subsequent unloading of the side skin.

[0160] The second cutting station includes a second loading and unloading position and a second cutting position. The second cutting station is provided with a second silicon rod transferring device. The second silicon rod transferring device is used to carry the silicon rod having two first side cut surfaces and transfer between the second loading and unloading position and the second cutting position along the transfer direction.

[0166] In some embodiments, the second transfer drive unit includes: a transfer screw and a screw drive source. The transfer screw is arranged along the transfer direction and is associated with the second bearing platform. The screw drive source is used to drive the transfer screw to rotate so that the associated second bearing platform moves along the transfer direction. The screw drive source can be, for example, a servo motor.

[0167] The second silicon rod cutting device is arranged on the second cutting station, and is used for performing a second cutting operation on the silicon rod at the second cutting position of the second cutting station and from the second silicon rod transferring device, so that the silicon rod is formed with two parallel second side cutting surfaces and at least one dividing surface located between the two second side cutting surfaces to obtain at least two half rods with a rectangular cross-section.

[0168] The second silicon rod cutting device includes at least one second wire cutting unit, which includes a plurality of second cutting wheels and a second cutting wire. The second cutting wire is sequentially wound around the plurality of second cutting wheels to form at least one second cutting wire saw. The second wire cutting unit moves relative to the second silicon rod transfer device at the second cutting station and the silicon rods carried by the second silicon rod transfer device, and the at least one second cutting wire saw performs a second cutting operation on the silicon rods carried by the second silicon rod transfer device. In some embodiments, the second cutting wire is wound between each second cutting wheel in a ring-shaped winding manner connected end to end. In this case, the second cutting wire can also be called a closed-loop cutting wire.

[0169] like Figure 1 As shown, the second silicon rod cutting device 15 includes two second wire cutting units 151 arranged in parallel, each of which includes: a plurality of second cutting wheels and a second cutting wire, the second cutting wire is wound around the plurality of second cutting wheels to form at least one second cutting wire saw, wherein the second cutting wire saw is arranged vertically or at an angle to the vertical.

[0170] See also Fig.13 , which is a schematic diagram of the structure of the second silicon rod cutting device in one embodiment. Fig.13 In the illustrated embodiment, the second silicon rod cutting device 15 includes two second wire cutting units 151. The second wire cutting unit 151 includes: a plurality of second cutting wheels 152 and a second cutting wire 154, the second cutting wire is wound around the plurality of second cutting wheels 152 to form at least one second cutting wire saw 155, wherein the second cutting wire saw 155 is arranged along the vertical direction or at an angle to the vertical direction. In addition, the second wire cutting unit 151 may also include a second cutting installation structure 150, on which the plurality of second cutting wheels 152 are arranged.

[0171] In some embodiments, the multiple second cutting wheels in the second wire cutting unit are connected to the second cutting mounting structure, or the multiple second cutting wheels are arranged on the second cutting mounting structure through a bracket, a connecting plate, or a mounting frame. The second cutting mounting structure serves as a carrier for associating the multiple second cutting wheels in the second wire cutting unit with the second cutting frame or the second cutting seat. The specific form of the second cutting mounting structure can be a beam body, a plate frame, a bracket, etc., which is not limited in this application.

[0172] In the integrated equipment for cutting and grinding small-sized rectangular rods of the present application, the second silicon rod cutting device includes a second cutting wire saw in a second wire cutting unit, which is arranged along the vertical direction or at an angle to the vertical direction.

[0173] In the second wire cutting unit, the second cutting wheel is provided with at least one second cutting wire groove for winding the cutting wire, and the second cutting wire groove can limit the position of the second cutting wire to control the cutting accuracy. Any second cutting wire saw is formed between the two second cutting wheels after the second cutting wire is wound around two second cutting wheels arranged opposite to each other. The positions of the two second cutting wheels and the positional relationship between the second cutting wheels can be used to determine the direction of the second cutting wire saw.

[0174] like Fig.13 As shown, in some embodiments, the second cutting installation structure 150 is a rectangular frame as a whole, and the second cutting unit includes a plurality of second cutting wheels 152, for example, four second cutting wheels 152, and the four second cutting wheels 152 are respectively arranged near the four corners of the second cutting installation structure 150, and the wheel surface of each second cutting wheel 152 is located in the vertical plane (the vertical plane is composed of the first direction and the third direction), wherein two second cutting wheels 152 are in the front (relatively closer to the second loading and unloading position) and arranged in parallel up and down, and the other two second cutting wheels 152 are in the back (relatively farther away from the second loading position) and arranged in parallel up and down, and the second cutting line 154 is wound around the four second cutting wheels 152 to form at least one second cutting wire saw 155 (for example, a second cutting wire saw 155 is formed between the two second cutting wheels 152 in the front and arranged in parallel up and down), and the second cutting wire saw 155 is arranged along the third direction (i.e., vertically). In addition, in order for the second cutting wire saw 155 to effectively cut the silicon rod, the second cutting wire saw 155 must interfere with the silicon rod in the vertical direction.

[0175] In some embodiments, the second cutting line is wound between the second cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Fig.13 In the illustrated embodiment, the second cutting line 154 is wound between the plurality of second cutting wheels 152 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0176] The multiple second cutting wheels in the second cutting unit are wound by a circular cutting wire. In this example, the second silicon rod cutting device can omit the wire storage drum, and the circular cutting wire can be driven by the cutting wire driving device to maintain high-speed operation. At the same time, the circular cutting wire can run in the same direction during the cutting operation. In this way, the second silicon rod cutting device can achieve high-precision second cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire operation or the running speed in the existing cutting method; at the same time, the circular cutting wire can effectively reduce the total length of the cutting wire required by the second wire cutting unit, reducing production costs.

[0177] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to the second cutting wheel, so that the second cutting line can be driven by the wound second cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the second cutting line to run, and this application does not limit it.

[0178] The second wire cutting unit in the present application may further include a second transition wheel, which is used to change the direction or guide the second cutting wire, or the second transition wheel may be used to adjust the tension of the second cutting wire. The number of the second transition wheels may be one or more according to the layout requirements.

[0179] The second transition wheel, while guiding and pulling the second cutting line, also serves as a tension wheel for adjusting the tension of the second cutting line. The tension wheel is used to adjust the tension of the second cutting line, which can reduce the probability of the second cutting line breaking and reduce consumables.

[0180] like Fig.13 As shown, in the second wire cutting unit, the second cutting installation structure 150 is a rectangular frame as a whole, and each second wire cutting unit 151 includes a plurality of second cutting wheels 152 and a plurality of second transition wheels 153, for example, two second cutting wheels 152 and two second transition wheels 153, which are respectively arranged near the four corners of the second cutting installation structure 150, and the wheel surfaces of the two second cutting wheels 152 and the two second transition wheels 153 are both located in the vertical plane, wherein the two second cutting wheels 152 are in the front and arranged in parallel up and down, and the two second transition wheels 153 are in the back and arranged in parallel up and down, and the second cutting wire 154 is wound around the two second cutting wheels 152 and the two second transition wheels 153 to form at least one second cutting wire saw 155 (for example, a second cutting wire saw 155 is formed between the two second cutting wheels 152), and at least one second cutting wire saw 155 is arranged vertically.

[0181] As before, the second cutting line 154 is wound around multiple second cutting wheels 152 or multiple second cutting wheels 152 and multiple second transition wheels 153 to form a second cutting line saw 155 between the two preceding second cutting wheels 152. Therefore, to adjust the line length of the second cutting line saw 155, the spacing between the two second cutting wheels 152 can be adjusted, and the implementation method includes changing the position of at least one of the two second cutting wheels 152.

[0182] The second cutting wire saw is located in the vertical plane and is arranged along the vertical direction or at an angle to the vertical direction, and the silicon rod carried by the second silicon rod transfer device at the corresponding second cutting station is placed horizontally (the axis of the silicon rod is arranged along the transfer direction). Therefore, in order to achieve the cutting of the silicon rod, the length of the second cutting wire saw is adapted to the size of the end face of the silicon rod. For example, the length of the second cutting wire saw must be greater than or equal to the diameter of the silicon rod or the chord length of the silicon rod at the cutting position.

[0183] The direction of the second cutting wheel surface corresponds to the direction of the second cutting wire saw. It should be understood that the second cutting wheel surface is parallel to the plane where any second cutting wire groove in the second cutting wheel is located. In order to control the cutting accuracy and the stability of the cutting process, the second cutting wire saw should be located in the plane where the second cutting wire groove for winding the second cutting wire is located; at the same time, during the cutting process, the force direction of the silicon rod on the second cutting wire must be parallel to the cutting wire groove, that is, the cutting wheel surface is parallel to the cutting direction. The cutting direction in the second cutting operation is the direction of the silicon rod axis, that is, the transfer direction (that is, the first direction X-axis).

[0184] The second silicon rod cutting device includes two second wire cutting units arranged in parallel, each of which has a second cutting wire saw, so the two second wire cutting units form two parallel cutting wire saws. Fig.13 In the illustrated embodiment, the second silicon rod cutting device comprises two second wire cutting units arranged in parallel along a second direction, each second wire cutting unit has a second cutting wire saw, and the second cutting wire saw is arranged vertically. Thus, the two second cutting wire saws belonging to the two second wire cutting units are arranged vertically.

[0185] In fact, the second cutting wire saw may still have other changes. In some embodiments, the second cutting wire saw is arranged along the vertical direction, but it is not limited to this. In other embodiments, the position of the second cutting wire saw may be located in the vertical plane and arranged at an angle to the vertical direction (i.e., the third direction), the vertical plane is composed of the first direction and the third direction, the angle is less than or equal to 10 degrees (≤10°), or the angle is less than or equal to 5 degrees (≤5°), or the angle is less than or equal to 3 degrees (≤3°), that is, the routing direction of the second cutting wire saw may be located in the vertical plane with the third direction (i.e., the vertical direction) and form an angle of less than or equal to 10 degrees (≤10°), less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°) with the third direction (i.e., the vertical direction). The angle here is not limited to an integer angle, and it may be any angle within a limited range, for example, 0.09°, 1.3°, 2.5°, 3°, etc. In some embodiments, in forming the second cutting wire saw, the upper second cutting wheel is in front in the first direction and the lower second cutting wheel is in the back in the first direction, and the second cutting wire saw formed can form a positive deflection angle with the vertical. In some embodiments, in forming the second cutting wire saw, the upper second cutting wheel is in the back in the first direction and the lower second cutting wheel is in the front in the first direction, and the second cutting wire saw formed can form a negative deflection angle with the vertical. The deflection angle (including positive deflection angle and negative deflection angle) can be changed according to the cutting process requirements and the size specifications of the silicon rod, for example, the angle of the deflection angle can be adjusted by changing the position of one or both of the two second cutting wheels arranged up and down related to the second cutting wire saw.

[0186] In some embodiments, the second wire cutting unit further includes a second tension adjustment mechanism. In wire cutting processing, the cutting wire tension affects the yield and processing accuracy in cutting. The second tension adjustment mechanism performs tension detection and adjusts the tension so that the tension of the second cutting wire reaches a certain threshold value set and maintains a constant value during cutting or a certain range allowed by the center of the value. In some embodiments, the second tension adjustment mechanism is associated with the second transition wheel 153 or the second cutting wheel. The second transition wheel 153 in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while realizing the guiding and traction of the second cutting wire 154.

[0187] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, current wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0188] In some embodiments, taking the tensioning wheel as the transition wheel as an example, the tension adjustment mechanism at least includes: a tension sensor, a servo motor and a screw rod; the tension sensor is arranged on the transition wheel, continuously senses the tension value of the cutting line on the transition wheel, 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 transition wheel, and the other end is connected to the servo motor, and when the servo motor is working, it pulls the transition wheel for unidirectional displacement to adjust the tension of the cutting line.

[0189] In some embodiments, the tension adjustment mechanism includes: a connecting rod assembly and a tension driving unit, the connecting rod assembly is associated with a transition wheel serving as a tensioning wheel 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 transition wheel to change its position to adjust the tension of the closed-loop cutting line.

[0190] Regarding the tension driving unit, in certain implementations, the tension driving unit may include a counterweight portion, and the counterweight portion may be associated with a connecting rod assembly. For example, taking a certain transition wheel as a tensioning wheel, when the tension of the closed-loop cutting line is to be increased, the counterweight portion is released, the counterweight portion is lowered, and the connecting rod assembly is driven by the gravity of the counterweight portion to move the associated tensioning wheel, thereby expanding the circumference of the figure surrounded by each cutting wheel and the transition wheel, and increasing the tension of the closed-loop cutting line. When the tension of the closed-loop cutting line is to be reduced, the counterweight portion is lifted, and the connecting rod assembly is driven by the gravity of the counterweight portion to move the associated tensioning wheel in the opposite direction, thereby expanding the circumference of the figure surrounded by each cutting wheel and the transition wheel, and reducing the tension of the closed-loop cutting line.

[0191] The counterweight part may include counterweight blocks, wherein the number of counterweight blocks may vary according to the requirements of closed-loop cutting line tension adjustment. For example, when the tension of the closed-loop cutting line is increased, the number of counterweight blocks may be increased, and when the tension of the closed-loop cutting line is reduced, the number of counterweight blocks may be reduced.

[0192] In some embodiments, the counterweight may include a locking mechanism for locking the counterweight so that the counterweight is stationary relative to the cutting mounting structure, so that the counterweight and the cutting mounting structure are switched from an active state to a locked state. In some examples, the locking mechanism may be, for example, a latch.

[0193] Still other changes may be made to the tension driving unit. For example, in some implementations, the tension driving unit may include a tension cylinder.

[0194] In some embodiments, the second silicon rod cutting device further comprises: at least one second distance adjustment mechanism, which is provided in at least one second wire cutting unit, and is used to drive a plurality of second cutting wheels in the second wire cutting unit to move in a direction perpendicular to the wheel surface of the cutting wheel. The second silicon rod cutting device can realize the switching of the second cutting wire between different cutting grooves of the second cutting wheel based on the distance adjustment mechanism, or adjust the position of the second cutting wire saw to change the cutting position (or processing specification) relative to the silicon rod.

[0195] In certain implementations, a second wire cutting unit in a second silicon rod cutting device is used as an example for description, and the second wire cutting unit includes a plurality of second cutting wheels and a plurality of second transition wheels. The carrier for carrying the plurality of second cutting wheels and the second transition wheel is, for example, a second cutting mounting structure, and the second distance adjustment mechanism can be used to drive the second cutting mounting structure as a whole to move along the perpendicular direction of the cutting wheel surface, and the second transition wheel and the second cutting wheel move along the perpendicular direction of the second cutting wheel surface (i.e., the transposition direction or the second direction Y axis) together with the second cutting mounting structure. In this state, the plurality of second cutting wheels and the second transition wheel are relatively stationary, that is, the positional relationship between the second transition wheel and the second cutting wheel remains unchanged. At this time, the second distance adjustment mechanism is used to adjust the cutting position of at least one second wire cutting wire saw in at least one second wire cutting unit relative to the silicon rod.

[0196] In some implementations, each second cutting wheel has at least two second cutting grooves, and different second cutting grooves are parallel to each other and have a cutting offset in the direction perpendicular to the wheel surface of the second cutting wheel. When the second distance adjustment mechanism is used to drive the multiple second cutting wheels in the second wire cutting unit to move relative to the second cutting mounting structure, the position of the groove around which the second cutting wire is wound on the second cutting wheel can be changed. In some implementations, the multiple second cutting wheels in the second wire cutting unit can be connected to a bracket, for example, wherein the bracket is movably arranged on the second cutting mounting structure and driven by the second distance adjustment mechanism to move along the direction perpendicular to the wheel surface of the second cutting wheel.

[0197] When at least one second distance adjusting mechanism is used to realize the change of the cutting wire grooves of the second cutting wire wound around the plurality of second cutting wheels in the at least one second wire cutting unit, in an actual scenario, the second cutting wire grooves corresponding to the cutting wires before and after the groove change can be predetermined, for example, the position of the second cutting wire before the groove change is the second cutting wire groove a1, and the second cutting wire is wound around the second cutting wire groove a2 after the groove change, and the displacement amount of the plurality of second cutting wheels in the second wire cutting unit driven by the second distance adjusting mechanism is determined based on the cutting offset between the second cutting wire groove a1 and the second cutting wire groove a2, that is, the displacement amount is set as the second cutting wire groove The cutting offset between groove a1 and the second cutting wire groove a2 can be used to realize the replacement of the second cutting wire from the second cutting wire groove a1 to the second cutting wire groove a2; it should be noted that at least one second distance adjustment mechanism drives the multiple second cutting wheels in the second wire cutting unit to move in the direction perpendicular to the second cutting wheel surface in the direction in which the cutting wire groove a2 points to the cutting wire groove a1. After the groove is changed, the cutting position of the second cutting wire saw in space remains unchanged, and the step of further calibrating the position of the second cutting wheel or other components is omitted, and the silicon rod can be cut according to the preset cutting amount, so that the groove changing process is simplified.

[0198] To further illustrate the implementation method of at least one second distance adjustment mechanism to move multiple second cutting wheels in the second wire cutting unit in a direction perpendicular to the wheel surface of the second cutting wheel, the present application discloses the following embodiments. When the number of second wire cutting units in the second silicon rod cutting device is different, the specific form of the at least one second distance adjustment mechanism can be changed accordingly.

[0199] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, and the single-wire cutting unit is a second wire cutting unit. The second distance adjustment mechanism includes: a screw, which is arranged along the orthogonal direction of the second cutting wheel surface and is threadedly connected to the single-wire cutting unit; and a screw driving source, which is used to drive the screw to rotate.

[0200] The single-wire cutting unit in the second silicon rod cutting device includes a plurality of second cutting wheels, and the second cutting wire is wound around the plurality of second cutting wheels to form at least one second cutting wire saw. The screw of the second distance adjustment mechanism has a distal end and a proximal end. In a specific implementation, for example, the proximal end of the screw can be connected to a screw drive source and rotated under the drive of the screw drive source, and the distal end of the screw is threadedly connected to the second single-wire cutting unit. Through the connection method at both ends of the screw, the screw can rotate based on the transmission of the screw drive source and convert the screw rotation into axial displacement by means of the threaded connection. The axial displacement direction is the setting direction of the screw, that is, the orthogonal direction of the cutting wheel surface; the displacement of the single-wire cutting unit in the orthogonal direction of the second cutting wheel surface can be achieved by driving the screw drive source in the second distance adjustment mechanism to rotate. The second cutting wheel of the single-wire cutting unit can be moved forward or backward in the orthogonal direction of the second cutting wheel surface by driving the screw to rotate in different directions.

[0201] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, and here, the single-wire cutting unit is a second wire cutting unit. The second distance adjustment mechanism includes: a telescopic member, which is arranged along the orthogonal direction of the second cutting wheel surface and is associated with the single-wire cutting unit; a telescopic member driving source, which is used to drive the telescopic member to perform telescopic movement along the orthogonal direction of the second cutting wheel surface. Here, the telescopic member can be set as a rod body structure and the extension direction of the rod body is the orthogonal direction of the second cutting wheel surface. The telescopic member can be telescopically moved along its extension direction under the drive of the telescopic member driving source. One end of the telescopic member can be connected to the telescopic member driving source, and the retractable free end is associated with the single-wire cutting unit, that is, the second cutting wheel of the single-wire cutting unit can be driven to move in the orthogonal direction of the second cutting wheel surface under the action of the telescopic member driving source. The telescopic member is, for example, an electric telescopic rod, or a connecting rod connected to a cylinder. The cylinder can be used as a telescopic member driving source, and this application does not limit it. The telescopic rod can be connected to the single-wire cutting unit in a linear connection or an indirect connection, for example, it can be directly connected to the second cutting mounting structure of the single-wire cutting unit, or indirectly connected to the second single-wire cutting unit through a support or a bearing. It should be understood that the extension or contraction of the telescopic member can correspond to the advancement or retreat of the single-wire cutting unit in the orthogonal direction of the second cutting wheel surface.

[0202] In the disclosed embodiments, the association can be achieved, for example, by one or more of snap-fit, screw-locking, bonding, and welding. For example, in the above embodiments, the telescopic rod can be associated with the second wire cutting unit by one or more of snap-fit, screw-locking, bonding, and welding; of course, the implementation method of the association is not limited to this, but is intended to achieve transmission in the second direction.

[0203] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, in which the single-wire cutting unit is a wire cutting unit. The second distance adjustment mechanism includes: a rack, which is arranged on the second single-wire cutting unit along the orthogonal direction of the second cutting wheel surface; a transmission gear, which is meshed with the rack; and a gear driving source, which is used to drive the transmission gear to rotate. The transmission gear rotates under the drive of the gear driving source, and the rack meshed with the transmission gear moves accordingly along the step direction of the rack. In this example, the rotational motion driven by the gear driving source can be converted into a wire transport along the direction of the rack by cooperating with the transmission gear. The rack is arranged on the second single-wire cutting unit along the orthogonal direction of the second cutting wheel surface, which can drive the second cutting wheel of the single-wire cutting unit to move along the orthogonal direction of the second cutting wheel surface. At the same time, the gear driving source controls the switching of the rotation direction of the transmission gear, so that the multiple second cutting wheels of the single-wire cutting unit can move forward or backward along the orthogonal direction of the second cutting wheel surface.

[0204] In certain embodiments, such as Fig.13As shown, the second silicon rod cutting device includes two second wire cutting units arranged in parallel and opposite to each other. At least one of the two second wire cutting units can be driven to move along the orthogonal direction of the second cutting wheel surface by at least one distance adjustment mechanism, so as to adjust the wire cutting wire saw spacing between the second cutting wire saws in the two second wire cutting units, or change the second cutting wire winding around the cutting wire grooves of multiple second cutting wheels in a second wire cutting unit.

[0205] At least one second distance adjustment mechanism can be configured to be connected to a second wire cutting unit, or to be associated with two second wire cutting units at the same time, so as to drive multiple second cutting wheels in the connected or associated one or two second wire cutting units to move along the orthogonal direction of the second cutting wheel surface.

[0206] In an embodiment, the second distance adjusting mechanism includes: a screw, which is arranged along the orthogonal direction of the second cutting wheel surface and is threadedly connected to a second wire cutting unit; and a screw driving source, which is used to drive the screw to rotate. The manner in which the multiple second cutting wheels in the second wire cutting unit to which the screw is driven and connected to the screw driving source move in the orthogonal direction of the second cutting wheel surface is similar to the aforementioned embodiment. The second cutting unit driven by the distance adjusting mechanism can be regarded as a single-wire cutting unit, which will not be described in detail here. It should be understood that by providing a second distance adjusting mechanism on any second wire cutting unit, the spacing between the parallel second cutting wire saws formed between the two second wire cutting units can be increased or decreased, and the second silicon rod cutting device can cut the silicon rods into different specifications.

[0207] In some embodiments, the second distance adjustment mechanism includes: a telescopic member, which is arranged along the orthogonal direction of the second cutting wheel surface and is associated with a second wire cutting unit; and a telescopic member driving source, which is used to drive the telescopic member to perform telescopic movement along the orthogonal direction of the second cutting wheel surface. Here, the second cutting unit provided with the second distance adjustment mechanism can be regarded as a single wire cutting unit, and the specific implementation method can refer to the above embodiment, which will not be repeated here.

[0208] In some embodiments, the second spacing mechanism includes: a spacing rack, which is along the orthogonal direction of the second cutting wheel surface and is associated with a second linear cutting unit; a transmission gear, which is meshed with the spacing rack; and a gear driving source, which is used to drive the transmission gear to rotate. Through the meshing transmission gear and the spacing rack, the gear driving source can control the spacing rack to move along the rack direction line, and the second linear cutting unit associated with the spacing rack can drive multiple second cutting wheels to move along the orthogonal direction of the second cutting wheel surface through the rack.

[0209] In some embodiments, the distance adjustment mechanism includes: a bidirectional screw, which is arranged along the orthogonal direction of the second cutting wheel surface and is threadedly connected to the two second wire cutting units; and a screw drive source, which is used to drive the screw to rotate so that the two second wire cutting units move toward or away from each other along the orthogonal direction of the second cutting wheel surface. In one embodiment, the bidirectional screw is a double-threaded screw, and the two ends of the bidirectional screw are respectively provided with threads and the thread directions are opposite. The screw drive source can be set at either end of the bidirectional screw to drive the bidirectional screw to rotate along the screw shaft. Through the threads with opposite directions at both ends of the bidirectional screw, when the bidirectional screw rotates under the drive of the screw drive source, the movement of the two ends of the bidirectional screw is converted into axial linear motion in opposite directions. The axial direction is the orthogonal direction of the second cutting wheel surface where the bidirectional screw is set. Driven by the screw drive source, the multiple second cutting wheels corresponding to the two second wire cutting units can move toward or away from each other.

[0210] In some embodiments, the second distance adjustment mechanism includes a servo motor provided on at least one second wire cutting unit. In actual scenarios, a servo motor is provided on at least one second wire cutting unit or each second wire cutting unit of the second silicon rod cutting device, and the servo motor controls the displacement of the corresponding second wire cutting unit in the orthogonal direction of the second cutting wheel surface. The second wire cutting unit can predetermine the cutting offset of the slot change or the adjustment amount of the cutting line changing the cutting position, and drive the multiple second cutting wheels in the second wire cutting unit to move along the orthogonal direction of the second cutting wheel surface with a preset displacement through the precise positioning function of the servo motor. For example, two second wire cutting units are provided in the second silicon rod cutting device, and at least one of the two second wire cutting units moves relatively independently along the orthogonal direction of the second cutting wheel surface under the drive of its corresponding servo motor. In some examples, the servo motor can also be replaced with a travel motor and a travel screw. It should be understood that the second distance adjustment mechanism is a driving device for driving the multiple second cutting wheels in the second wire cutting unit to move relative to each other, and its specific form is not limited in this application.

[0211] As before, in the second silicon rod cutting device, the second cutting wire saws of the two second wire cutting units arranged in parallel are arranged along the vertical direction or at an angle to the vertical direction, driving the second silicon rod transfer device and the silicon rod carried by it to move along the transfer direction, and the second wire cutting unit and the second silicon rod transfer device move relatively along the transfer direction, and the second cutting wire saws in the two second wire cutting units perform the second cutting operation on the silicon rod carried by the second silicon rod transfer device. The silicon rod is cut by the second wire cutting unit so that a cutting surface and a side skin are formed on the silicon rod, that is, a cutting wire saw in a second wire cutting unit cuts the silicon rod so that a cutting surface is formed on the silicon rod, and a side skin is cut off, therefore, the second cutting wire saws in the two second wire cutting units arranged in parallel in the second silicon rod cutting device perform the second cutting operation on the silicon rod with a circular cross section so that two parallel second side cut surfaces are formed on the silicon rod.

[0212] In addition to the second wire cutting unit, the second silicon rod cutting device also includes at least one third wire cutting unit, wherein the at least one third wire cutting unit is formed with at least one third cutting wire saw, and the at least one third cutting wire saw is located in the vertical plane and arranged along the vertical direction or arranged at an angle to the vertical direction. The at least one third cutting wire saw is used to perform a second cutting operation on the silicon rod carried by the second silicon rod carrying device so that the silicon rod is formed with at least one cutting surface to obtain at least two half rods with a rectangular cross-section.

[0213] The third wire cutting unit includes a plurality of third cutting wheels and a third cutting wire, and the third cutting wire is sequentially wound around the plurality of third cutting wheels to form at least one third cutting wire saw arranged vertically or at an angle to the vertical. The third wire cutting unit moves relative to the second silicon rod transfer device at the second cutting station and the silicon rods carried by the third cutting wire saw, and the silicon rods carried by the second silicon rod transfer device are cut by the third cutting wire saw. In some embodiments, the third cutting wire is wound between the third cutting wheels in a ring-shaped winding manner with the ends connected. In this case, the third cutting wire can also be called a closed-loop cutting wire.

[0214] In certain embodiments, such as Fig.13 As shown, the second silicon rod cutting device 15 includes a third wire cutting unit 156 located between the two second wire cutting units 151, and the third wire cutting unit includes: a plurality of third cutting wheels and a third cutting wire, the third cutting wire is wound behind the plurality of third cutting wheels to form at least one third cutting wire saw, wherein the third cutting wire saw is arranged along the vertical direction or at an angle to the vertical direction.

[0215] like Fig.13 As shown, the second silicon rod cutting device 15 includes a third wire cutting unit 156 between two second wire cutting units 151. The third wire cutting unit 156 includes: a plurality of third cutting wheels 157 and a third cutting wire 158, the third cutting wire 158 is wound around the plurality of third cutting wheels 157 to form at least one third cutting wire saw 159, wherein the third cutting wire saw 159 is arranged along the vertical direction or at an angle to the vertical direction. Fig.13As shown, the second silicon rod cutting device 15 may include two second wire cutting units 151 and a third wire cutting unit 156, each second wire cutting unit 151 has a second cutting wire saw 155, and each third wire cutting unit 156 has a third cutting wire saw 159. Therefore, the second silicon rod cutting device 15 may include two second cutting wire saws 155 and one third cutting wire saw 159, and the two second cutting wire saws 155 and one third cutting wire saw 159 are arranged along the vertical direction or at an angle to the vertical direction. Among them, the third cutting wire saw 159 is located between the two second cutting wire saws 155 and is centrally arranged. The third cutting wire saw 159 performs a second cutting operation on the silicon rod, and the silicon rod can be cut into two half rods of the same size. However, this is not limited to this. In some embodiments, the third cutting wire saw 159 is located between the two second cutting wire saws 155 but is not centrally arranged. The third cutting wire saw 159 performs a second cutting operation on the silicon rod, and the silicon rod can be cut into two half rods of different sizes. In some embodiments, the second silicon rod cutting device includes a third wire cutting unit, the wire cutting unit includes two or more third cutting wire saws, the two or more third cutting wire saws are parallel to each other and are arranged vertically or at an angle to the vertical. In some embodiments, the second silicon rod cutting device includes two or more third wire cutting units, and two or more third cutting wire saws in the two or more third wire cutting units are parallel to each other and are arranged vertically or at an angle to the vertical. The silicon rod is cut into three or more half rods of the same or different sizes by two or more third cutting wire saws. In this application, for the convenience of description, the cut parts of the silicon rod are all referred to as half rods. In fact, when the number of third cutting wire saws is two or more, the cut part of the silicon rod is likely to be less than 1 / 2 of the whole silicon rod. Therefore, "half rod" can also use other terms, such as "small rectangular rod", "divided rod", "sub-rod", "small silicon rod", "small square rod" and so on.

[0216] In addition, it should be noted that, since the second silicon rod cutting device includes at least one third wire cutting unit, in the second silicon rod transfer device, the second carrying platform is provided with at least one wire receiving groove corresponding to the at least one third cutting wire saw. Fig.13In the illustrated embodiment, the second silicon rod cutting device 15 includes a third wire cutting unit 156 between two second wire cutting units 151, and the third wire cutting unit 156 has a third cutting wire saw 159. Therefore, the second carrying platform 141 in the second silicon rod transfer device 14 is provided with a wire accommodating groove 142 corresponding to the third cutting wire saw 159. The wire accommodating groove 142 is arranged along the transfer direction (i.e., the first direction), and the width of the wire accommodating groove 142 is greater than the third cutting wire saw 159 to accommodate the third cutting wire saw 159. In some embodiments, the width of the wire accommodating groove is much greater than the wire diameter of the third cutting wire saw (for example, greater than or equal to 5 times or 10 times the wire diameter of the third cutting wire saw) to provide displacement of the third cutting wire saw in the width direction of the wire accommodating groove (i.e., the transposition direction or the second direction Y axis). In some embodiments, the second silicon rod cutting device includes two or more third cutting wire saws (in some embodiments, the second silicon rod cutting device includes a third wire cutting unit, and the wire cutting unit includes two or more third cutting wire saws; or, in some embodiments, the second silicon rod cutting device includes two or more third wire cutting units, and each third wire cutting unit includes at least one third cutting wire saw), then, two or at least two wire accommodating grooves corresponding to the two or more third cutting wire saws are provided on the second supporting platform.

[0217] In such Fig.13 In the illustrated embodiment, each third cutting wheel 157 in the third wire cutting unit 156 is coaxially arranged with each second cutting wheel 152 in a second wire cutting unit 151 next to it, that is, the third cutting wheel 157 in the third wire cutting unit is coaxially arranged with the corresponding second cutting wheel 152 in a second wire cutting unit 151 next to it and is arranged on the second cutting installation structure 150. However, this is not limited to this, in some embodiments, the third wire cutting unit 156 may include a third cutting installation structure, and the aforementioned plurality of third cutting wheels 157 may be arranged on the third cutting installation structure.

[0218] In the integrated equipment for cutting and grinding small-sized rectangular rods of the present application, the third cutting wire saw in the third wire cutting unit included in the second silicon rod cutting device is arranged along the vertical direction or at an angle to the vertical direction.

[0219] In the third wire cutting unit, the third cutting wheel is provided with at least one third cutting wire groove for winding the cutting wire, and the third cutting wire groove can limit the position of the third cutting wire to control the cutting accuracy. Any third cutting wire saw is formed between the two third cutting wheels after the third cutting wire is wound around two third cutting wheels arranged opposite to each other. The positions of the two third cutting wheels and the positional relationship between the third cutting wheels can be used to determine the direction of the third cutting wire saw.

[0220] like Fig.13As shown, in some embodiments, the third cutting unit includes a plurality of third cutting wheels 157, for example, four third cutting wheels 157, the four third cutting wheels 157 are arranged in a rectangular shape, and the wheel surface of each third cutting wheel 157 is located in a vertical plane (the vertical plane is composed of the first direction and the third direction), wherein two third cutting wheels 157 are in front (relatively closer to the second loading and unloading area) and arranged in parallel up and down, and the other two third cutting wheels 157 are in the back (relatively farther from the second loading area) and arranged in parallel up and down, and the third cutting wire 158 is wound around the four third cutting wheels 157 to form at least one third cutting wire saw 159 (for example, the third cutting wire saw 159 is formed between the two third cutting wheels 157 in front and arranged in parallel up and down), and the third cutting wire saw 159 is arranged along the third direction (i.e., vertical direction). In addition, in order to enable the third cutting wire saw 159 to effectively cut the silicon rod, the third cutting wire saw 159 should interfere with the silicon rod in the vertical direction.

[0221] In some embodiments, the third cutting line is wound between the third cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Fig.13 In the illustrated embodiment, the third cutting line 158 is wound between the plurality of third cutting wheels 157 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0222] The multiple third cutting wheels in the third cutting unit are wound by a circular cutting wire. In this example, the second silicon rod cutting device can omit the wire storage drum, and the circular cutting wire can be driven by the cutting wire driving device to maintain high-speed operation. At the same time, the circular cutting wire can run in the same direction during the cutting operation. In this way, the second silicon rod cutting device can achieve high-precision second cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire operation or the running speed in the existing cutting method; at the same time, the circular cutting wire can effectively reduce the total length of the cutting wire required by the third wire cutting unit, reducing production costs.

[0223] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to the third cutting wheel, so that the third cutting line can be driven by the wound third cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the third cutting line to run, and this application does not limit it. As mentioned above, in some embodiments, each third cutting wheel in the third wire cutting unit is coaxially arranged with each second cutting wheel in a second wire cutting unit next to it. Therefore, each third cutting wheel in the third wire cutting unit can be driven by the cutting line driving device in the second wire cutting unit, and it is unnecessary to configure a corresponding cutting line driving device for the third wire cutting unit.

[0224] The third wire cutting unit in the present application may further include a third transition wheel, which is used to change direction or guide the third cutting wire, or the third transition wheel may be used to adjust the tension of the third cutting wire. The number of the third transition wheels may be one or more according to the layout requirements.

[0225] The third transition wheel, while guiding and pulling the third cutting line, also serves as a tension wheel for adjusting the tension of the third cutting line. The tension wheel is used to adjust the tension of the third cutting line, which can reduce the probability of the third cutting line breaking and reduce consumables.

[0226] like Fig.13 As shown, for example, in some embodiments, the third wire cutting unit 156 includes multiple third cutting wheels 157 and multiple third transition wheels 157', for example, two third cutting wheels 157 and two third transition wheels 157', and the wheel surfaces of the two third cutting wheels 157 and the two third transition wheels 157' are both located in the vertical plane, wherein the two third cutting wheels 157 are in the front and arranged in parallel up and down, and the two third transition wheels 157' are in the back and arranged in parallel up and down, and the third cutting wire 158 is wound around the two third cutting wheels 157 and the two third transition wheels 157' to form at least one third cutting wire saw 159 (for example, a third cutting wire saw 159 is formed between the two third cutting wheels 157), and at least one third cutting wire saw 159 is arranged vertically.

[0227] As before, the third cutting line 158 is wound around multiple third cutting wheels 157 or multiple third cutting wheels 157 and multiple third transition wheels 157' to form a third cutting line saw 159 between the two preceding third cutting wheels 157. Therefore, to adjust the line length of the third cutting line saw 159, the spacing between the two third cutting wheels 157 can be adjusted, and the implementation method includes changing the position of at least one of the two third cutting wheels 157.

[0228] The third cutting wire saw is arranged vertically or at an angle to the vertical, and the silicon rod carried by the second silicon rod transfer device at the corresponding second cutting station is placed horizontally (the axis of the silicon rod is arranged along the transfer direction). Therefore, in order to achieve the cutting of the silicon rod, the length of the third cutting wire saw is adapted to the size of the end face of the silicon rod. For example, the length of the third cutting wire saw must be greater than or equal to the diameter of the silicon rod or the chord length of the silicon rod at the cutting position.

[0229] The direction of the third cutting wheel surface corresponds to the direction of the third cutting wire saw. It should be understood that the third cutting wheel surface is parallel to the plane where any third cutting wire groove in the third cutting wheel is located. In order to control the cutting accuracy and the stability of the cutting process, the third cutting wire saw should be located in the plane where the third cutting wire groove used for winding the third cutting wire is located; at the same time, during the cutting process, the force direction of the silicon rod on the third cutting wire must be parallel to the cutting wire groove, that is, the cutting wheel surface is parallel to the cutting direction. The cutting direction in the second cutting operation is the direction of the silicon rod axis, that is, the transfer direction (that is, the first direction X-axis).

[0230] The second silicon rod cutting device includes a third wire cutting unit located between the two second wire cutting units and arranged in parallel with the two second wire cutting units. The third wire cutting unit has a third cutting wire saw, which is arranged along the vertical direction or at an angle to the vertical direction.

[0231] In fact, the third cutting wire saw may still have other changes. In some embodiments, the third cutting wire saw is arranged along the vertical direction, but it is not limited to this. In other embodiments, the position of the third cutting wire saw may be located in the vertical plane and arranged at an angle to the vertical direction (i.e., the third direction). The vertical plane is composed of the third direction and the third direction, and the angle is less than or equal to 10 degrees (≤10°), or the angle is less than or equal to 5 degrees (≤5°), or the angle is less than or equal to 3 degrees (≤3°). That is, the routing direction of the third cutting wire saw may be located in the vertical plane with the third direction (i.e., the vertical direction) and form an angle with the third direction (i.e., the vertical direction) of less than or equal to 10 degrees (≤10°), less than or equal to 5 degrees (≤5°), or less than or equal to 3 degrees (≤3°). The angle here is not limited to an integer angle, and it may be any angle within a limited range, for example, 0.09°, 1.3°, 2.5°, 3°, etc. In some embodiments, in the two third cutting wheels arranged up and down to form the third cutting wire saw, the upper third cutting wheel is in front in the first direction and the lower third cutting wheel is in the back in the first direction, and the third cutting wire saw formed can form a positive deflection angle with the vertical. In some embodiments, in the two third cutting wheels arranged up and down to form the third cutting wire saw, the upper third cutting wheel is in the back in the first direction and the lower third cutting wheel is in the front in the first direction, and the third cutting wire saw formed can form a negative deflection angle with the vertical. The deflection angle (including positive deflection angle and negative deflection angle) can be changed according to the cutting process requirements and the size specifications of the silicon rod, for example, the angle of the deflection angle can be adjusted by changing the position of one or both of the two third cutting wheels arranged up and down related to the third cutting wire saw.

[0232] In some embodiments, the third wire cutting unit further includes a third tension adjustment mechanism. In wire cutting processing, the cutting wire tension affects the yield and processing accuracy of cutting, and the third tension adjustment mechanism performs tension detection and adjusts the tension so that the tension of the third cutting wire reaches a certain threshold value set and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0233] In some embodiments, the third tension adjustment mechanism is associated with the third transition wheel or the third cutting wheel. The third transition wheel in the wire cutting unit not only guides and pulls the third cutting wire 158, but also serves as a tensioning wheel for adjusting the tension of the cutting wire.

[0234] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, current wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0235] In some embodiments, taking the tensioning wheel as the transition wheel as an example, the tension adjustment mechanism at least includes: a tension sensor, a servo motor and a screw rod; the tension sensor is arranged on the transition wheel, continuously senses the tension value of the cutting line on the transition wheel, 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 transition wheel, and the other end is connected to the servo motor, and when the servo motor is working, it pulls the transition wheel for unidirectional displacement to adjust the tension of the cutting line.

[0236] In some embodiments, the tension adjustment mechanism includes: a connecting rod assembly and a tension driving unit, the connecting rod assembly is associated with a transition wheel serving as a tensioning wheel 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 transition wheel to change its position to adjust the tension of the closed-loop cutting line.

[0237] Regarding the tension driving unit, in certain implementations, the tension driving unit may include a counterweight portion, and the counterweight portion may be associated with a connecting rod assembly. For example, taking a certain transition wheel as a tensioning wheel, when the tension of the closed-loop cutting line is to be increased, the counterweight portion is released, the counterweight portion is lowered, and the connecting rod assembly is driven by the gravity of the counterweight portion to move the associated tensioning wheel, thereby expanding the circumference of the figure surrounded by each cutting wheel and the transition wheel, and increasing the tension of the closed-loop cutting line. When the tension of the closed-loop cutting line is to be reduced, the counterweight portion is lifted, and the connecting rod assembly is driven by the gravity of the counterweight portion to move the associated tensioning wheel in the opposite direction, thereby expanding the circumference of the figure surrounded by each cutting wheel and the transition wheel, and reducing the tension of the closed-loop cutting line.

[0238] The counterweight part may include counterweight blocks, wherein the number of counterweight blocks may vary according to the requirements of closed-loop cutting line tension adjustment. For example, when the tension of the closed-loop cutting line is increased, the number of counterweight blocks may be increased, and when the tension of the closed-loop cutting line is reduced, the number of counterweight blocks may be reduced.

[0239] In some embodiments, the weight portion may include a locking mechanism. In some examples, the locking mechanism may be, for example, a latch.

[0240] The tension driving unit may still be modified in other ways. For example, in some implementations, the tension driving unit may include a tension cylinder.

[0241] In some embodiments, the second silicon rod cutting device further includes: at least one third distance adjustment mechanism, which is provided in at least one third wire cutting unit, and is used to drive a plurality of third cutting wheels in the third wire cutting unit to move in a direction perpendicular to the wheel surface of the cutting wheel. The second silicon rod cutting device can realize the switching of the third cutting wire between different cutting grooves of the third cutting wheel based on the distance adjustment mechanism, or adjust the position of the third cutting wire saw to change the cutting position (or processing specification) relative to the silicon rod.

[0242] In some implementations, a third wire cutting unit in the second silicon rod cutting device is used as an example for explanation, and the third wire cutting unit includes a plurality of third cutting wheels and a plurality of third transition wheels. The third distance adjustment mechanism can be used to drive the plurality of third cutting wheels and the plurality of third transition wheels to move along the vertical direction of the cutting wheel surface (i.e., the transposition direction or the second direction Y axis). In this state, the third cutting wheel and the third transition wheel are relatively stationary, that is, the positional relationship between the third transition wheel and the third cutting wheel remains unchanged. At this time, the third distance adjustment mechanism is used to adjust the cutting position of at least one third wire cutting wire saw in the third wire cutting unit relative to the silicon rod.

[0243] Each third cutting wheel has at least two third cutting grooves, different third cutting grooves are parallel to each other and there is a cutting offset in the vertical direction of the third cutting wheel surface between different third cutting grooves. When the third distance adjustment mechanism is used to drive the movement of multiple third cutting wheels in the third wire cutting unit, the position of the groove on the third cutting wheel where the third cutting wire is wound can be changed.

[0244] When at least one third distance adjusting mechanism is used to realize the change of the cutting wire grooves of the plurality of third cutting wheels in the at least one third wire cutting unit around which the third cutting wire is wound, in an actual scenario, the third cutting wire grooves corresponding to the cutting wires before and after the groove change can be predetermined, for example, the position of the third cutting wire before the groove change is the third cutting wire groove a1, and the third cutting wire is wound around the third cutting wire groove a2 after the groove change, and the displacement amount of the plurality of third cutting wheels in the third wire cutting unit driven by the third distance adjusting mechanism is determined based on the cutting offset amount between the third cutting wire groove a1 and the third cutting wire groove a2, that is, the displacement amount is set as the third cutting wire groove The cutting offset between groove a1 and the third cutting line groove a2 can be used to realize the replacement of the third cutting line from the third cutting line groove a1 to the third cutting line groove a2; it should be noted that at least one third distance adjustment mechanism drives multiple third cutting wheels in the third wire cutting unit to move in the direction perpendicular to the wheel surface of the third cutting wheel in the direction in which the cutting line groove a2 points to the cutting line groove a1. After the groove is changed, the cutting position of the third cutting wire saw in space remains unchanged, and the step of further calibrating the position of the third cutting wheel or other components is omitted, and the silicon rod can be cut according to the preset cutting amount, so that the groove changing process is simplified.

[0245] To further illustrate the implementation method of at least one third distance adjustment mechanism to move multiple third cutting wheels in the third wire cutting unit in a direction perpendicular to the wheel surface of the third cutting wheel, the present application discloses the following embodiments. When the number of third wire cutting units in the second silicon rod cutting device is different, the specific form of the at least one third distance adjustment mechanism can be changed accordingly.

[0246] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, and the single-wire cutting unit is a third wire cutting unit. The third distance adjustment mechanism includes: a screw, which is arranged along the orthogonal direction of the wheel surface of the third cutting wheel and is threadedly connected to the single-wire cutting unit; and a screw driving source, which is used to drive the screw to rotate.

[0247] The single-wire cutting unit in the second silicon rod cutting device includes a plurality of third cutting wheels, and the third cutting wire is wound around the plurality of third cutting wheels to form at least one third cutting wire saw. The screw of the third distance adjustment mechanism has a distal end and a proximal end. In a specific implementation, for example, the proximal end of the screw can be connected to a screw drive source and rotated under the drive of the screw drive source, and the distal end of the screw is threadedly connected to the third single-wire cutting unit. Through the connection method at both ends of the screw, the screw can rotate based on the transmission of the screw drive source and convert the screw rotation into axial displacement by means of threaded connection. The axial displacement direction is the setting direction of the screw, that is, the orthogonal direction of the cutting wheel surface; the displacement of the single-wire cutting unit in the orthogonal direction of the third cutting wheel surface can be achieved by driving the screw drive source in the third distance adjustment mechanism to rotate. The rotation direction of the screw driven to rotate is different, so that the third cutting wheel of the single-wire cutting unit can be moved forward or backward in the orthogonal direction of the third cutting wheel surface.

[0248] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, and here, the single-wire cutting unit is a third-wire cutting unit. The third distance adjustment mechanism includes: a telescopic member, which is arranged along the orthogonal direction of the wheel surface of the third cutting wheel and is associated with the single-wire cutting unit; a telescopic member driving source, which is used to drive the telescopic member to perform telescopic movement along the orthogonal direction of the wheel surface of the third cutting wheel. Here, the telescopic member can be set as a rod body structure and the extension direction of the rod body is the orthogonal direction of the wheel surface of the third cutting wheel. The telescopic member can be telescopically moved along its extension direction under the drive of the telescopic member driving source. One end of the telescopic member can be connected to the telescopic member driving source, and the retractable free end is associated with the single-wire cutting unit, that is, the third cutting wheel of the single-wire cutting unit can be driven to move in the orthogonal direction of the wheel surface of the third cutting wheel under the action of the telescopic member driving source. The telescopic member is, for example, an electric telescopic rod, or a connecting rod connected to a cylinder. The cylinder can be used as a telescopic member driving source, and this application does not limit it. The telescopic rod can be connected to the single-wire cutting unit in a linear connection or an indirect connection, for example, it can be directly connected to the third cutting mounting structure of the single-wire cutting unit, or indirectly connected to the third single-wire cutting unit through a support or a bearing. It should be understood that the extension or contraction of the telescopic member can correspond to the advancement or retreat of the single-wire cutting unit along the orthogonal direction of the third cutting wheel surface.

[0249] Here, the association can be achieved, for example, by one or more of snap-fitting, screw locking, bonding, and welding. For example, in the above embodiment, the telescopic rod can be associated with the third wire cutting unit by one or more of snap-fitting, screw locking, bonding, and welding; of course, the implementation method of the association is not limited to this, but is intended to achieve transmission in the second direction.

[0250] In some embodiments, the second silicon rod cutting device includes a single-wire cutting unit, in which the single-wire cutting unit is a wire cutting unit. The third distance adjustment mechanism includes: a rack, which is arranged on the third single-wire cutting unit along the orthogonal direction of the wheel surface of the third cutting wheel; a transmission gear, which is meshed with the rack; and a gear driving source, which is used to drive the transmission gear to rotate. The transmission gear rotates under the drive of the gear driving source, and the rack meshed with the transmission gear moves accordingly along the step direction of the rack. In this example, the rotational motion driven by the gear driving source can be converted into wire transport along the direction of the rack by cooperating with the transmission gear. The rack is arranged on the third single-wire cutting unit along the orthogonal direction of the wheel surface of the third cutting wheel, which can drive the third cutting wheel of the single-wire cutting unit to move along the orthogonal direction of the wheel surface of the third cutting wheel. At the same time, the gear driving source controls the switching of the rotation direction of the transmission gear, so that the multiple third cutting wheels of the single-wire cutting unit can move forward or backward along the orthogonal direction of the wheel surface of the third cutting wheel.

[0251] In certain embodiments, the second silicon rod cutting device includes two third wire cutting units arranged in parallel and opposite to each other, and at least one of the two third wire cutting units can be driven to move along the orthogonal direction of the third cutting wheel surface by at least one distance adjustment mechanism, so as to adjust the wire cutting wire saw spacing between the third cutting wire saws in the two third wire cutting units, or change the third cutting wire wound around the cutting wire grooves of multiple third cutting wheels in a third wire cutting unit.

[0252] At least one third distance adjustment mechanism can be configured to be connected to a third wire cutting unit, or simultaneously associated with two third wire cutting units, to drive multiple third cutting wheels in the connected or associated one or two third wire cutting units to move along the orthogonal direction of the third cutting wheel surface.

[0253] The third distance adjustment mechanism includes: a screw, which is arranged along the orthogonal direction of the wheel surface of the third cutting wheel and is threadedly connected to a third wire cutting unit; and a screw drive source, which is used to drive the screw to rotate. The way in which the multiple third cutting wheels in the third wire cutting unit to which the screw is driven and connected to the screw drive source move in the orthogonal direction of the wheel surface of the third cutting wheel is similar to the aforementioned embodiment. The third cutting unit driven by the distance adjustment mechanism can be regarded as a single-wire cutting unit, which will not be described in detail here. It should be understood that by providing a third distance adjustment mechanism on any third wire cutting unit, the spacing between the parallel third cutting wire saws formed between the two third wire cutting units can be increased and decreased, and the second silicon rod cutting device can cut the silicon rods into different specifications.

[0254] In some embodiments, the third distance adjustment mechanism includes: a telescopic member, which is arranged along the orthogonal direction of the third cutting wheel surface and is associated with a third wire cutting unit; and a telescopic member driving source, which is used to drive the telescopic member to perform telescopic movement along the orthogonal direction of the third cutting wheel surface. Here, the third cutting unit provided with the third distance adjustment mechanism can be regarded as a single wire cutting unit, and the specific implementation method can refer to the above embodiment, which will not be repeated here.

[0255] The third spacing mechanism includes: a spacing rack, which is along the orthogonal direction of the third cutting wheel surface and is associated with a third linear cutting unit; a transmission gear, which is meshed with the spacing rack; and a gear driving source, which is used to drive the transmission gear to rotate. Through the meshing transmission gear and the spacing rack, the gear driving source can control the spacing rack to move along the rack direction line, and the third linear cutting unit associated with the spacing rack can drive multiple third cutting wheels to move along the orthogonal direction of the third cutting wheel surface through the rack.

[0256] In some embodiments, the distance adjustment mechanism includes: a bidirectional screw, which is arranged along the orthogonal direction of the third cutting wheel surface and is threadedly connected to the two third wire cutting units; and a screw drive source, which is used to drive the screw to rotate so that the two third wire cutting units move toward or away from each other along the orthogonal direction of the third cutting wheel surface. In one embodiment, the bidirectional screw is a double-threaded screw, and the two ends of the bidirectional screw are respectively provided with threads and the thread directions are opposite. The screw drive source can be set at either end of the bidirectional screw to drive the bidirectional screw to rotate along the screw shaft. Through the threads with opposite directions at both ends of the bidirectional screw, when the bidirectional screw rotates under the drive of the screw drive source, the movement of the two ends of the bidirectional screw is converted into axial linear motion in opposite directions. The axial direction is the orthogonal direction of the third cutting wheel surface where the bidirectional screw is set. Driven by the screw drive source, the multiple third cutting wheels corresponding to the two third wire cutting units can move toward or away from each other.

[0257] In some embodiments, the third distance adjustment mechanism includes a servo motor provided on at least one third wire cutting unit. In actual scenarios, a servo motor is provided on at least one third wire cutting unit or each third wire cutting unit of the second silicon rod cutting device, and the servo motor controls the displacement of the corresponding third wire cutting unit in the orthogonal direction of the third cutting wheel surface. The third wire cutting unit can predetermine the cutting offset of the slot change or the adjustment amount of the cutting line change cutting position, and drive the multiple third cutting wheels in the third wire cutting unit to move along the orthogonal direction of the third cutting wheel surface with a preset displacement through the precise positioning function of the servo motor. For example, two third wire cutting units are provided in the second silicon rod cutting device, and at least one of the two third wire cutting units moves relatively independently along the orthogonal direction of the third cutting wheel surface under the drive of its corresponding servo motor. In some examples, the servo motor can also be replaced with a travel motor and a travel screw. It should be understood that the third distance adjustment mechanism is a driving device for driving the multiple third cutting wheels in the third wire cutting unit to move relative to each other, and its specific form is not limited in this application.

[0258] As before, in the second silicon rod cutting device, a third wire cutting unit is arranged between the two second wire cutting units. The third cutting wire saw in the third wire cutting unit is arranged vertically or at an angle to the vertical, driving the second silicon rod transfer device and the silicon rod it carries to move along the transfer direction. The third wire cutting unit and the second silicon rod transfer device are relatively moved along the transfer direction, and the third cutting wire saw in the third wire cutting unit performs a second cutting operation on the silicon rod carried by the second silicon rod transfer device, so that the silicon rod forms a cutting surface and two half rods are obtained. In the second silicon rod cutting device, two or more third wire cutting units are arranged between the two second wire cutting units. The third cutting wire saw in each third wire cutting unit is arranged vertically or at an angle to the vertical. In this way, the second silicon rod transfer device and the silicon rods it carries are driven to move along the transfer direction. The two or more third wire cutting units and the second silicon rod transfer device are relatively moved along the transfer direction. The third cutting wire saws in the two or more third wire cutting units perform a second cutting operation on the silicon rods carried by the second silicon rod transfer device, so that the silicon rods are formed with two or more cutting surfaces to obtain three or more half rods with rectangular cross-sections.

[0259] The half-rod cutting device comprises a second edge skin anti-collapse device cooperating with the second silicon rod transferring device, which is used to stabilize the edge skin when the second silicon rod cutting device performs the second cutting operation on the silicon rod.

[0260] It should be understood that the silicon rods carried by the second silicon rod transfer device are horizontal, that is, the axis of the silicon rods is consistent with the transfer direction (i.e., the first direction X axis). Therefore, the edge skin formed by the second silicon rod cutting device performing the second cutting operation on the silicon rods is also horizontal.

[0261] In some embodiments, the second edge skin anti-collapse device includes a clamping support and an edge skin clamp, wherein the edge skin clamp is arranged on the clamping support and is used to clamp the edge skin.

[0264] The second silicon rod transfer device includes a second edge skin anti-collapse device, which cooperates with the second silicon rod transfer device and is used to clamp the end face of the silicon rod during the second cutting operation to prevent edge collapse.

[0265] In the present application, the second edge skin anti-collapse device may be the same as the first edge skin anti-collapse device mentioned above. Therefore, for the specific structure and working principle of the second edge skin anti-collapse device, please refer to the description of the first edge skin anti-collapse device mentioned above, and only a brief description is given here.

[0266] In some embodiments, the second edge skin anti-collapse device includes: a clamping support and an edge skin clamp.

[0267] In some embodiments, the clamping support of the second edge skin anti-collapse device is associated with the second supporting platform of the second silicon rod transfer device, that is, the clamping support of the second edge skin anti-collapse device and the second supporting platform of the second silicon rod transfer device can move forward and backward together.

[0269] The chuck driving mechanism is used to drive at least one end face chuck of at least one pair of end face chucks to move along the clamping direction to adjust the clamping distance between the at least one pair of end face chucks.

[0270] In some embodiments, the chuck driving mechanism includes: a chuck moving guide rail arranged along the clamping direction; and a chuck driving unit for driving at least one end face chuck of at least one pair of end face chucks to move along the chuck moving guide rail.

[0271] In certain embodiments, a chuck moving guide rail may be provided between the second end face chuck and the second end face chuck in at least one pair of end face chucks.

[0272] In some embodiments, the chuck driving unit includes at least one chuck telescopic assembly. The chuck telescopic assembly includes: a chuck telescopic rod and a chuck telescopic cylinder, the chuck telescopic rod is arranged along the clamping direction and is associated with a corresponding end face chuck, and the chuck telescopic cylinder is associated with the chuck telescopic rod. In some embodiments, the chuck driving mechanism is used to drive two end face chucks in a pair of end face chucks to move toward or away from each other along the clamping direction, and the chuck driving mechanism includes a pair of chuck telescopic assemblies, wherein each chuck telescopic assembly corresponds to an end face chuck, the chuck telescopic rod in the chuck telescopic assembly is arranged along the clamping direction and is associated with a corresponding end face chuck, and the chuck telescopic cylinder in the chuck telescopic assembly is associated with the chuck telescopic rod. By using the chuck telescopic cylinders in a pair of chuck telescopic assemblies to control the corresponding chuck telescopic rod to retract or extend, a pair of end face chucks can be driven to move toward or away from each other along the movable guide rails on the movable guide rod or movable guide beam. In certain embodiments, the chuck driving mechanism is used to drive one end face chuck of a pair of end face chucks to move toward or away from the other end face chuck along the clamping direction, and the chuck driving mechanism includes a chuck telescopic assembly corresponding to the end face chuck to be moved, wherein the chuck telescopic rod in the chuck telescopic assembly is arranged along the clamping direction and associated with the corresponding end face chuck, and the chuck telescopic cylinder in the chuck telescopic assembly is associated with the chuck telescopic rod. The chuck telescopic cylinder in the chuck telescopic assembly is used to control the corresponding chuck telescopic rod to retract or extend, so that the corresponding end face chuck can be driven to move along the movable guide rail on the movable guide rod or movable guide beam toward or away from the other end face chuck.

[0273] In certain embodiments, the chuck drive unit includes: at least one pair of clamping racks, a drive gear, and a gear drive source.

[0274] In certain embodiments, the chuck driving unit includes: at least one pair of clamping racks, a linkage gear, and a chuck driving source.

[0275] In some embodiments, the chuck driving unit includes: at least one chuck clamping assembly, and the chuck clamping assembly includes: a clamping screw and a screw driving source.

[0276] In some embodiments, the chuck drive unit includes: a bidirectional screw and a screw drive source, wherein the bidirectional screw is arranged along the clamping direction, and both ends of the bidirectional screw are respectively provided with threads and the thread directions are opposite, and the two ends of the bidirectional screw are respectively associated with at least one pair of end face chucks, and the screw drive source is associated with the bidirectional screw.

[0277] At least one pair of end face clamps are arranged opposite to each other along the clamping direction, and are used for correspondingly clamping the two end faces of the silicon rod.

[0278] In some embodiments, for any one of at least a pair of end face chucks, the end face chuck includes a clamping base and a side skin pressing piece provided on the clamping base, and the side skin pressing piece is used to press the side skin to be cut in the silicon rod.

[0279] In some embodiments, the clamping base may be, for example, a clamping substrate, the size of which is adapted to the edge skin to be cut, that is, the clamping substrate at least partially or completely covers the edge skin to be cut.

[0280] In some embodiments, the edge skin pressing member includes an edge skin pressing screw disposed on the clamping substrate, and the number of the edge skin pressing screws may be one or more. In practical applications, the edge skin pressing screw is used to press the edge skin to be cut, which can ensure that the edge skin to be cut in the silicon rod remains stable during the second cutting operation.

[0281] Of course, in some embodiments, in the end face chuck, the edge skin pressing member may also include an edge skin pressing elastic member disposed on the clamping base. For example, in some embodiments, the edge skin pressing elastic member includes an edge skin pushing rod, which is sleeved with a compression spring.

[0282] In this way, when the second silicon rod cutting device is used to perform the second cutting operation on the silicon rod, the second silicon rod transferring device carries the silicon rod, and the chuck driving mechanism in the second edge skin collapse prevention device drives at least one end face chuck of at least one pair of end face chucks to move along the clamping direction, so that at least one pair of end face chucks clamps the two end faces of the silicon rod, wherein the edge skin pressing piece in the end face chuck presses on the edge skin to be cut in the silicon rod, which can ensure that the edge skin to be cut in the silicon rod remains stable during the second cutting operation, and can avoid the edge skin falling off or the edge skin and the silicon rod body being offset to cause edge collapse when the second cutting wire saw in the second wire cutting unit penetrates the silicon rod to completely cut it off.

[0283] In some embodiments, for any one of at least one pair of end face chucks, the end face chuck includes a silicon rod pressing piece, a side skin pressing piece, and a side skin clamping reinforcement piece, wherein the silicon rod pressing piece is used to press the main body of the silicon rod, the side skin pressing piece is used to press the side skin to be cut in the silicon rod, and the side skin clamping reinforcement piece is used to apply additional clamping force to the side skin. In the present application, a silicon rod with a circular cross-section is formed into a square silicon rod with a rectangular cross-section after a square cutting operation, wherein the main body of the silicon rod refers to the portion that at least includes the square silicon rod, that is, the main body of the silicon rod is relative to the side skin, and the main body of the silicon rod is the portion that includes the square silicon rod, and the main body of the silicon rod changes in different square cutting operations.

[0284] In some embodiments, the clamping base may be, for example, a clamping substrate, the size of which is adapted to the end face of the silicon rod and the side skin to be cut, that is, the clamping substrate at least covers part of the silicon rod body and part of the side skin. The clamping substrate covers part of the silicon rod body so that the silicon rod pressing piece disposed thereon can act on the silicon rod body. The clamping substrate also covers part of the side skin so that the side skin pressing piece and the side skin clamping reinforcement disposed thereon can act on the side skin.

[0285] In certain embodiments, the silicon rod pressing member includes a silicon rod pressing screw disposed on a clamping substrate, and the edge skin pressing member includes an edge skin pressing screw disposed on a clamping substrate. The number of silicon rod pressing screws may be one or more, and the number of edge skin pressing screws may be one or more. In practical applications, the silicon rod pressing screw is used to press the main body of the silicon rod, and the edge skin pressing screw is used to press the edge skin to be cut. Under the condition that the silicon rod pressing screw presses the main body of the silicon rod and the edge skin pressing screw presses the edge skin to be cut, it can ensure that the main body of the silicon rod and the edge skin remain relatively stable, and it can be avoided that the edge skin falls off when the cutting wire saw in the wire cutting unit passes through the silicon rod to completely cut off, or the edge skin and the main body of the silicon rod are offset to cause edge collapse.

[0286] It is easy to know that in some cases, the end surface of the silicon rod is not an ideal flat surface, and it may happen that one of the silicon rod pressing piece and the side skin pressing piece cannot effectively resist and press the corresponding silicon rod body or side skin.

[0287] In order to make the silicon rod pressing piece and the side skin pressing piece arranged on the clamping base adapt to the end face of the silicon rod to achieve effective pressing, the end face clamp also includes an offset fine-tuning structure for adjusting the position of the clamping base. The offset fine-tuning structure can be used to partially adjust the position of the clamping base, thereby changing the position of the silicon rod pressing piece and the side skin pressing piece arranged on the clamping base.

[0288] In some embodiments, the deflection fine-tuning structure adopts a ball head structure or a similar structure, and the clamping base is arranged by the ball head structure. In some embodiments, the ball head or the hemispherical head is connected to the clamping base through a connecting rod, and the ball head or the hemispherical head is embedded in a receiving cavity.

[0289] In some embodiments, the deflection fine-tuning structure adopts a hinge structure, and the clamping base is arranged by the hinge structure. For example, the clamping base is associated with the mounting structure by the hinge structure, and can deflect to a certain extent relative to the mounting structure.

[0290] In addition, in some embodiments, in the end face chuck, the silicon rod pressing member includes a silicon rod pressing elastic member provided on the clamping base, and the side skin pressing member includes a side skin pressing elastic member provided on the clamping base. For example, in some embodiments, the silicon rod pressing elastic member includes a silicon rod push rod, which is sleeved with a compression spring; the side skin pressing elastic member includes a side skin push rod, which is sleeved with a compression spring. In some embodiments, the silicon rod pressing elastic member includes a silicon rod push block, whose rear end is provided with a compression spring; the side skin pressing elastic member includes a side skin push block, whose rear end is provided with a compression spring.

[0291] The end face chuck also includes a side skin clamping reinforcement member, which can move forward and backward relative to the clamping base along the clamping direction. When the side skin clamping reinforcement member moves forward relative to the clamping base, the side skin clamping reinforcement member can provide a strong clamping force on the corresponding side skin. Generally, the clamping force applied by the side skin clamping reinforcement member on the side skin is greater than the top pressure applied by the silicon rod pressing member on the silicon rod body and the top pressure applied by the side skin pressing member on the side skin.

[0292] In some embodiments, the edge skin clamping reinforcement includes a telescopic top rod or a telescopic top block and a telescopic driving source, and the telescopic top rod or the telescopic top block is controlled by the telescopic driving source to move forward and backward relative to the clamping base. In some embodiments, a through hole is provided on the clamping base plate, and the telescopic driving source and the telescopic top rod or the telescopic top block are arranged on a mounting structure, and the telescopic driving source can drive the telescopic top rod or the telescopic top block to extend out of the clamping base plate and press against the corresponding edge skin, or drive the telescopic top rod or the telescopic top block to retract into the clamping base plate. The telescopic driving source can be, for example, a telescopic cylinder.

[0293] The end face chuck can still be changed in other embodiments. In some embodiments, the end face chuck includes: a second clamping base and a second clamping base, wherein a silicon rod pressing piece is arranged on the second clamping base, and a side skin pressing piece and a side skin clamping reinforcement piece that moves forward and backward relative to the second clamping base along the clamping direction are arranged on the second clamping base.

[0294] In some embodiments, the second clamping base may be, for example, a clamping substrate, whose size is adapted to the end face of the silicon rod body, that is, the second clamping substrate at least covers a portion of the silicon rod body so that the silicon rod pressing piece disposed thereon can act on the silicon rod body. The second clamping base may be, for example, a clamping substrate, whose size is adapted to the end face of the edge skin to be cut, that is, the second clamping substrate at least covers a portion of the edge skin so that the edge skin pressing piece disposed thereon can act on the edge skin.

[0295] In the end face chuck, the silicon rod pressing member includes a silicon rod pressing screw provided on the second clamping substrate, and the number of the silicon rod pressing screws can be one or more. The edge skin pressing member includes an edge skin pressing screw provided on the second clamping substrate, and the number of the edge skin pressing screws can be one or more. In practical applications, the silicon rod pressing screw is used to press the silicon rod body, and the edge skin pressing screw is used to press the edge skin to be cut. Under the condition that the silicon rod pressing screw presses the silicon rod body and the edge skin pressing screw presses the edge skin to be cut, it can ensure that the silicon rod body and the edge skin remain relatively stable, and it can avoid the edge skin falling off or the edge skin and the silicon rod body offset and causing edge collapse when the cutting wire saw in the wire cutting unit passes through the silicon rod to completely cut off.

[0296] In addition, in some embodiments, in the end face chuck, the silicon rod pressing member includes a silicon rod pressing elastic member provided on the second clamping base, and the side skin pressing member includes a side skin pressing elastic member provided on the second clamping base. For example, in some embodiments, the silicon rod pressing elastic member includes a silicon rod push rod, which is sleeved with a compression spring; the side skin pressing elastic member includes a side skin push rod, which is sleeved with a compression spring. In some embodiments, the silicon rod pressing elastic member includes a silicon rod push block, whose rear end is provided with a compression spring; the side skin pressing elastic member includes a side skin push block, whose rear end is provided with a compression spring.

[0297] The end face chuck also includes a side skin clamping reinforcement member, which can move forward and backward relative to the second clamping base along the clamping direction. When the side skin clamping reinforcement member moves forward relative to the second clamping base, the side skin clamping reinforcement member can provide a strong clamping force on the corresponding side skin. Generally, the clamping force applied by the side skin clamping reinforcement member to the side skin is greater than the top pressure applied by the silicon rod pressing member to the silicon rod body and the top pressure applied by the side skin pressing member to the side skin.

[0298] In some embodiments, the side skin clamping reinforcement includes a telescopic top rod or a telescopic top block that is controlled to advance and retreat relative to the second clamping base. For example, the side skin clamping reinforcement includes a telescopic top rod or a telescopic top block and a telescopic driving source, and the telescopic driving source drives the telescopic top rod or the telescopic top block to advance and retreat relative to the second clamping base. In some embodiments, a through hole is provided on the second clamping base, and the telescopic driving source and the telescopic top rod or the telescopic top block are arranged on a mounting structure. The telescopic driving source can drive the telescopic top rod or the telescopic top block to extend out of the second clamping base and press against the corresponding side skin, or drive the telescopic top rod or the telescopic top block to retract into the second clamping base. Among them, the telescopic driving source can be, for example, a telescopic cylinder.

[0299] In this way, when the second silicon rod cutting device is used to perform the second cutting operation on the silicon rod, the second silicon rod transferring device carries the silicon rod, and the chuck driving mechanism in the second edge skin anti-collapse device drives at least one end face chuck of at least a pair of end face chucks to move along the clamping direction, so that at least a pair of end face chucks clamp the two end faces of the silicon rod, wherein the silicon rod pressing piece in the end face chuck presses on the main body of the silicon rod, the edge skin pressing piece in the end face chuck presses on the edge skin to be cut in the silicon rod, and the edge skin clamping reinforcement piece in the end face chuck is in a retracted state (in the retracted state, the edge skin clamping reinforcement piece is recessed in the clamping base, or protrudes from the clamping base but the protruding height relative to the clamping base is also smaller than the protruding height of the silicon rod pressing piece and the edge skin pressing piece relative to the clamping base), so that the edge skin and the main body of the silicon rod remain relatively still, which can avoid the edge skin falling off or the edge skin and the main body of the silicon rod being offset when the cutting wire saw in the wire cutting unit passes through the silicon rod to completely cut off, resulting in edge collapse. After the edge skin is cut, the edge skin clamping reinforcement in the driving end face chuck extends relative to the clamping base and presses against the cut edge skin. The clamping force applied by the edge skin clamping reinforcement on the edge skin is greater than the pressing force applied by the silicon rod pressing piece on the silicon rod body and the pressing force applied by the edge skin pressing piece on the edge skin. At this time, at least one pair of end face chucks can be operated to move the cut edge skin.

[0300] In the present application, the second edge skin collapse prevention device may further include an edge skin clamp advance and retreat mechanism for driving the edge skin clamp to advance and retreat along an advance and retreat direction.

[0301] In an embodiment in which the end face chuck includes a clamping base and a side skin pressing piece arranged on the clamping base, after the side skin cutting is completed, the side skin clamp is driven to withdraw in the forward and backward direction by the side skin clamp advance and retreat mechanism, and the pressing pressure applied to the side skin by the pressing piece can drive the clamped side skin to separate from the silicon rod body.

[0302] In an embodiment in which the end face chuck includes a clamping base, a silicon rod pressing piece and a side skin pressing piece arranged on the clamping base, and a side skin clamping reinforcement piece which advances and retreats relative to the clamping base in a clamping direction, after the side skin cutting is completed, the side skin clamping reinforcement piece in the end face chuck is driven to extend relative to the clamping base and press against the cut side skin. At this time, the side skin clamp is driven to retreat in the advance and retreat direction by the side skin clamp advance and retreat mechanism. The clamping force applied by the side skin clamping reinforcement piece on the side skin is greater than the pressing force applied by the silicon rod pressing piece on the silicon rod body and the pressing force applied by the side skin pressing piece on the side skin, thereby driving the clamped side skin to separate from the silicon rod body.

[0303] In some embodiments, the edge skin clamp advance and retreat mechanism includes: a clamp advance and retreat guide rail, arranged along the advance and retreat direction; and an edge skin clamp advance and retreat unit, used to drive the edge skin clamp to move along the clamp advance and retreat guide rail.

[0304] In some embodiments, the edge skin clamp advance and retreat unit includes: a clamp seat telescopic rod and a clamp seat telescopic cylinder, the clamp seat telescopic rod is arranged along the advance and retreat direction and is associated with the clamp seat of the edge skin clamp, and the clamp seat telescopic cylinder is associated with the clamp seat telescopic rod.

[0305] In some embodiments, the edge skin clamp advance and retreat unit includes: the edge skin clamp advance and retreat mechanism includes: a clamp seat rack, arranged along the advance and retreat direction and associated with the clamp seat of the edge skin clamp; a clamp seat gear, meshing with the clamp seat rack; a gear driving source, associated with the clamp seat gear, used to drive the clamp seat gear to rotate so that the meshed edge skin clamp moves along the advance and retreat direction. The gear driving source can be, for example, a servo motor.

[0306] In some embodiments, the edge skin clamp advance and retreat unit includes: an exit screw and a screw drive source, wherein the exit screw is arranged along the advance and retreat direction and is associated with the clamp seat of the edge skin clamp, and the screw drive source is associated with the exit screw. The screw drive source may be, for example, a servo motor.

[0307] In the present application, the second edge skin anti-collapse device may also include a clamp lifting mechanism for driving the edge skin clamp to move up and down in the vertical direction. In some embodiments, the edge skin clamp is moved up or down in the vertical direction by the clamp lifting mechanism to adapt to the size of the silicon rods carried by the silicon rod transfer. For example, if the size of the silicon rod is large, the edge skin clamp is driven to move up in the vertical direction by the clamp lifting mechanism, and if the size of the silicon rod is small, the edge skin clamp is driven to move down in the vertical direction by the clamp lifting mechanism.

[0308] In some embodiments, the fixture lifting mechanism includes: a fixture lifting rail and a fixture lifting unit, wherein the fixture lifting rail is arranged vertically. The fixture lifting unit is used to drive the edge skin fixture to move up and down along the fixture lifting rail.

[0309] In some embodiments, the edge clamp lifting unit includes: a lifting screw and a screw drive source, the lifting screw is arranged vertically and associated with the clamping seat of the edge skin clamp, and the screw drive source is associated with the lifting screw.

[0310] In some embodiments, the clamp lifting unit includes: a lifting rack, a lifting gear, and a gear driving source, wherein the lifting rack is arranged vertically and associated with the clamp seat of the edge skin clamp, the lifting gear is meshed with the lifting rack, and the gear driving source is associated with the lifting gear, and is used to drive the lifting gear to rotate so that the meshed edge skin clamp moves vertically. The gear driving source can be, for example, a servo motor.

[0311] Thus, when the second edge skin anti-collapse device is used, the silicon rod is placed horizontally on the silicon rod carrying platform of the silicon rod transfer device; the edge skin clamp is driven by the clamp lifting mechanism in the second edge skin anti-collapse device to move vertically up and down to adjust the position; the edge skin clamp advance and retreat mechanism in the second edge skin anti-collapse device drives the edge skin clamp to advance in the advance and retreat direction and approach the silicon rod; the clamp driving mechanism in the second edge skin anti-collapse device drives at least one end face clamp of at least one pair of end face clamps to move in the clamping direction until the silicon rod pressing piece on the end face clamp presses against the silicon rod body and the edge skin pressing piece on the end face clamp presses against the edge skin to be cut. Afterwards, the silicon rod cutting device performs a square cutting operation on the silicon rod to form the silicon rod body and the edge skin. After the edge skin is cut, the edge skin clamping reinforcement in the driving end face chuck extends relative to the clamping base and presses against the cut edge skin. At this time, the edge skin clamp is driven to withdraw along the advance and retreat direction through the edge skin clamp advance and retreat mechanism.

[0336] In some implementations, when a pair of clamp arms are to be driven, two clamp arm driving units may be provided, each of which includes a moving rack, a driving gear, and a gear driving source. In practical applications, for each clamp arm, the gear driving source drives the driving gear to rotate so that the associated clamp arm moves along the moving rack. In this way, the two clamp arm driving units are used to drive the corresponding clamp arms to move, and the two clamp arms can be driven to move toward each other (the two clamp arms are moved closer to each other to reduce the clamping distance between the two clamp arms) or move away from each other (the two clamp arms are moved away from each other to increase the clamping distance between the two clamp arms) along the moving rack.

In practical applications, the driving gear is driven by a servo motor to rotate so that the associated two relative clamp arm mounting seats and their clamp arms move toward each other (the two clamp arms move closer to each other to reduce the clamping distance between the two clamp arms) or move away from each other (the two clamp arms move away from each other to increase the clamping distance between the two clamp arms) along the moving racks.

[0338] The clamp arm driving unit includes: a movable screw rod, which is arranged along the transfer direction and associated with the corresponding clamp arm; and a screw rod driving source, which is used to drive the movable screw rod to rotate so that the associated clamp arm moves along the transfer direction.

In practical applications, the moving screw is driven by the screw driving source to rotate so that the associated clamp arm moves along the transfer direction, for example, moves closer to the other clamp arm (reducing the clamping distance between the two clamp arms) or moves away from the other clamp arm (increasing the clamping distance between the two clamp arms).

[0340] In certain implementations, when a pair of clamp arms are to be driven, two clamp arm driving units may be provided, each clamp arm driving unit including a moving screw and a screw driving source, wherein each moving screw is associated with a corresponding clamp arm. In practical applications, for each clamp arm, the screw driving source drives the moving screw to rotate so that the associated clamp arm moves along the transfer direction. In this way, the two clamp arm driving units are used to drive the corresponding clamp arms to move, and the two clamp arms can be driven to move toward each other (the two clamp arms are moved closer to each other to reduce the clamping distance between the two clamp arms) or move away from each other (the two clamp arms are moved away from each other to increase the clamping distance between the two clamp arms) along the moving rack.

[0341] When a pair of clamp arms need to be driven, a clamp arm driving unit may be provided, the clamp arm driving unit comprising a moving screw and a screw driving source, wherein the moving screw may be, for example, a bidirectional screw, with threads at both ends of the bidirectional screw respectively provided and with threads in opposite directions, and the two ends of the bidirectional screw are respectively associated with a pair of relative clamp arms. In practical applications, the bidirectional screw is driven to rotate by the screw driving source so that the two relative clamp arms associated with each other move toward each other (the two clamp arms approach each other to reduce the clamping distance between the two clamp arms) or move away from each other (the two clamp arms move away from each other to increase the clamping distance between the two clamp arms) along the moving rack.

[0342] Of course, the clamp arm driving unit can still be changed in other ways. For example, in some embodiments, the clamp arm driving unit may include a telescopic cylinder, and the two ends of the telescopic cylinder are respectively associated with a pair of clamp arms arranged opposite to each other. Alternatively, in some embodiments, the clamp arm driving unit includes a clamp arm telescopic assembly, and the clamp arm telescopic assembly includes: a clamp arm telescopic rod and a clamp arm telescopic cylinder, the clamp arm telescopic rod is associated with a corresponding clamp arm, and the clamp head telescopic cylinder is associated with the clamp head telescopic rod.

[0343] In addition, in some embodiments, the clamp arm is a rotating structure, for example, the silicon rod clamp further includes a clamp arm rotating mechanism, which is used to drive the clamp arm to rotate. In some implementations, the clamp arm rotating mechanism is provided on at least one clamp arm of at least one pair of clamp arms, and any one clamping portion of at least one pair of clamp arms or two clamping portions of a pair of clamp arms are provided with a rotatable structure, and the clamping portion of the clamp arm is driven by the clamp arm rotating mechanism to rotate in the direction of the axis of the silicon rod, and the clamped silicon rod rotates accordingly about the axis of the silicon rod. For example, in some examples, the clamping arm rotation mechanism may be a rotating motor, and the clamping parts of the two clamping arms in a pair of clamping arms are provided with a rotatable structure, and the clamping parts of the two clamping arms or the clamping parts of one of the clamping arms are connected to the output shaft of the rotating motor. For example, the clamping parts of the two clamping arms are respectively connected to a rotating motor, and the two rotating motors respectively drive the clamping parts of the corresponding clamping arms to rotate, or the clamping part of one of the clamping arms is connected to the rotating motor, and the rotating motor drives the clamping part of the corresponding clamping arm to rotate, and utilizes the friction force to conduct through the clamped silicon rod, so as to drive the clamping part of the other clamping arm to rotate.

[0344] In some embodiments, the clamping portion of at least one pair of clamping arms has a contact surface for clamping a silicon rod or a half rod. The contact surface is arranged on a rotatable platform, and the cross section of the platform can be arranged in a custom regular geometric shape or irregular geometric shape.

[0345] In some embodiments, the rotatable platform can be configured as a whole hinged by a hinge device with a locking function, and can rotate along the axis of the transfer direction. The axis of the rotation axis is connected to the clamp arm rotation mechanism.

[0346] In some embodiments, the clamping portion of the clamping arm may be configured as a rotatable truncated cone, the circular plane of which contacts the end face of the silicon rod and remains relatively still with the end face of the silicon rod after being pressed against the end face of the silicon rod. The clamping portion also includes a locking structure, and the clamping portion is in a locked state when the silicon rod is subjected to corresponding processing operations (the processing operations may be, for example, cutting, etc.). When the silicon rod is switched, such as when the cutting position is switched, the clamping portion rotates along the center of the truncated cone driven by the clamping arm rotation mechanism.

[0347] In some embodiments, the clamping portion of the clamping arm includes a rotatable truncated cone and a series of protruding contacts arranged on the truncated cone, and each contact has a contact plane. The truncated cone rotates under the drive of the clamping arm rotation mechanism. In one implementation of this embodiment, the protruding length of the contact, that is, the position in the transfer direction, can be adjusted, so that in the process of clamping the silicon rod, for the silicon rod with a low end surface flatness, the protruding length of the contact can be adjusted according to the end surface of the silicon rod, so that each contact surface is in a close contact state with the end surface of the silicon rod. The protruding length is the length in the transfer direction from the circular plane of the truncated cone to the contact plane of the contact.

[0348] In some embodiments, the clamping portion of the silicon rod clamp is provided with a pressure sensor to adjust the protruding length of the contact based on the detected pressure state. Generally, in the process of clamping the silicon rod, a pair of clamping arms of the silicon rod clamp are driven by the clamping arm driving mechanism to approach each other along the transfer direction until the contact surface of the clamping portion contacts the end face of the silicon rod to be clamped. When the clamping portion is provided with multiple contacts and the pressure value detected that the contact between some contacts and the end face of the silicon rod is less than a set value or a set area, the protruding length of the contact can be adjusted (generally in the direction of approaching the end face of the silicon rod) to change the clamping degree; or, each clamping portion of a pair of clamping arms of the silicon rod clamp is provided with a contact surface. In the process of clamping the silicon rod, the clamping arm driving mechanism drives the end faces of the pair of clamping arms facing the two ends of the silicon rod to approach each other to achieve that after the clamping portion contacts the end face of the silicon rod, the clamping degree of the silicon rod is detected by the pressure sensor. When the set pressure range is reached, the clamping arm driving mechanism controls the pair of clamping arms to stop moving toward each other.

[0349] The clamp arm rotation mechanism may be disposed on one of the pair of clamp arms (the other clamp arm only has a rotation function) to drive the clamping parts of the pair of clamp arms and the clamped silicon rod or half rod to rotate; or the clamp arm rotation mechanism may be disposed on each clamp arm of the pair of clamp arms and coordinately control the two clamping parts of the pair of clamp arms to rotate at the same angle and direction. In some implementations, the clamp arm rotation mechanism may include a drive motor.

[0350] When the silicon rod cutting device is used to cut the silicon rod, the clamping part can be driven to rotate by the clamping arm rotating mechanism. Usually, when cutting a single crystal silicon rod, the clamping arm rotating mechanism controls the clamping part to rotate a certain angle, such as 90°, so that the silicon rod cutting device can be used to cut one side or two opposite sides of the silicon rod.

[0351] In the integrated equipment for cutting and grinding small rectangular rods of the present application, the silicon rod loading and unloading device further includes a centering adjustment mechanism for adjusting the position of the silicon rod so that the axis of the silicon rod corresponds to the predetermined center line. Figure 2 (or Figure 4), the centering adjustment mechanism 175 includes at least two clamping assemblies arranged at intervals along the transfer direction, each clamping assembly includes two clamping members arranged relatively on the clamping arm mounting seat along the clamping direction and a telescopic drive unit associated with the two clamping members, and the telescopic drive unit is used for the two clamping members to telescopically move relative to the clamping arm mounting seat in the clamping direction, wherein the clamping direction is perpendicular to the transfer direction and forms a horizontal plane, that is, the clamping direction is the second direction. The clamping member can be, for example, a clamping plate or a clamping strip, and the telescopic drive unit can be, for example, a telescopic cylinder or a servo motor with a screw. In practical applications, when the silicon rod is horizontally placed on the first silicon rod transfer device for the first cutting operation or placed on the second silicon rod transfer device for the second cutting operation, the silicon rod needs to be centered by operating at least two clamping assemblies in the centering adjustment mechanism, that is, the telescopic drive unit in the clamping assembly drives the two clamping members to retract relative to the clamping arm mounting seat in the clamping direction, and the silicon rod between the two can be clamped to complete the centering operation, which is simple and fast to operate.

[0352] The fixture transposition mechanism is used to drive the silicon rod fixture to move along the transposition direction.

The transposition rack is arranged along the transposition direction, the driving gear is arranged on the silicon rod fixture and meshes with the transposition rack, and the gear drive source is used to drive the driving gear to rotate so that the associated silicon rod fixture moves along the transposition direction.

[0354] In such Figure 1 and Figure 2 (or Figure 4) In the embodiment shown in FIG. 1 , the fixture transposition drive unit includes: a transposition rack, a driving gear, and a gear drive source. The transposition rack is arranged along the transposition direction, and the length range of the transposition guide in the transposition direction at least covers the positions of the respective cutting stations and the silicon rod cutting device in the half-rod cutting equipment, so as to ensure that the silicon rod fixture can be transferred to each cutting station. The movable rack can adopt a rack structure. The driving gear is arranged on the fixture mounting frame of the silicon rod fixture and meshes with the transposition rack. The gear drive source is arranged on the fixture mounting frame of the silicon rod fixture and is associated with the driving gear. In practical applications, the gear drive source can be used to drive the driving gear to rotate so as to drive the silicon rod fixture to move along the transposition direction through the transposition rack.

The transposition direction is perpendicular to the transfer direction and forms a horizontal plane, that is, Figure 1 The second direction is the Y axis.

[0364] In some embodiments, the adsorption member transposition drive unit includes: a transposition rack, a driving gear, and a gear drive source. The transposition rack is arranged along the transposition direction, is arranged on the side skin adsorption member and is meshed with the transposition rack. The gear drive source is used to drive the driving gear to rotate so that the associated side skin adsorption member moves along the transposition direction.

[0365] In such Figure 1 and Figure 3 (or Figure 4 ) In the embodiment shown in FIG. 1 , the adsorption member transposition drive unit includes: a transposition rack, a driving gear, and a gear driving source. The transposition rack is arranged along the transposition direction, and the length range of the transposition guide rail in the transposition direction at least covers the positions of the corresponding cutting stations and silicon rod cutting devices in the integrated equipment for cutting and grinding small-sized rectangular rods, so as to ensure that the adsorption member can be transferred to cover each cutting station. The movable rack can adopt a rack structure. The driving gear is arranged on the adsorption member mounting frame of the edge skin adsorption member and meshes with the transposition rack. The gear driving source is arranged on the adsorption member mounting frame of the edge skin adsorption member and is associated with the driving gear. In actual applications, the gear driving source can be used to drive the driving gear to rotate to drive the edge skin adsorption member to move along the transposition direction through the transposition rack. For example, the driving gear is driven by the gear driving source to rotate forward, and the driving gear and the transposition rack cooperate to drive the associated silicon rod clamp forward in the transposition direction; the driving gear is driven by the gear driving source to rotate reversely, and the driving gear and the transposition rack cooperate to drive the associated silicon rod clamp backward in the transposition direction.

[0366] Of course, the structure of the adsorption component transposition drive unit can still be changed in other ways. For example, in some embodiments, the adsorption component transposition drive unit may include: a transposition screw, which is arranged along the transposition direction and associated with the adsorption component mounting frame of the side skin adsorption component; a screw drive source, which is used to drive the transposition screw to rotate so that the associated side skin adsorption component moves along the transposition direction. The chain conveying mechanism includes an annular chain and a chain drive source, and the annular chain is associated with the adsorption component mounting frame of the side skin adsorption component. The ring chain can be, for example, a closed-loop chain, which is wound around a plurality of movable gears to form a preset shape, and the chain drive source can be, for example, a servo motor.

[0367] In certain embodiments, the half-rod cutting device of the present application may further include a peel edge recovery box or a peel edge recovery vehicle, and the peel edge unloading device 18 is used to unload the peel edge into the peel edge recovery box or the peel edge recovery vehicle.

[0368] The half-rod cutting device of the present application may also include a material unloading conveying device, which is arranged at the unloading area and is used to convey the ground half-rods. In some embodiments, the material unloading conveying device may be, for example, a conveyor belt device, including a conveyor belt, which is wound around two conveyor rollers arranged opposite to each other in the front and rear directions, and at least one of the two conveyor rollers is connected to a material unloading drive source, which may be, for example, a servo motor. Figure 1 and Figure 2 (or Figure 4 ) In the embodiment shown in FIG. 1 , the half-rod grinding equipment also includes a material unloading conveying device 179.

[0369] The integrated equipment for cutting and grinding small rectangular rods of the present application also includes a crystal line detection device. In some embodiments, the crystal line detection device includes: at least two support structures arranged at a distance, the support structure having a support roller group arranged along the transfer direction for supporting the silicon rod to be cut; a roller driving source for driving each support roller in the support roller group to rotate so as to drive the silicon rod to be cut to rotate; and a crystal line measuring probe located between the at least two support structures.

[0370] At least two supporting structures are arranged at intervals along the transfer direction, and each supporting structure has a supporting roller group, wherein the supporting roller group includes two or more rollers arranged along the transfer direction, and each roller belonging to the same supporting roller group is connected by a rotating shaft arranged along the transfer direction, and when the supporting roller group is used to support the silicon rod to be cut, the wheel surface of each roller in the supporting roller group contacts the silicon rod to be cut. In addition, in this embodiment, the at least two supporting structures arranged at intervals along the transfer direction can also be movable, that is, at least one bearing structure of the at least two supporting structures can be moved along the transfer direction to adjust the support spacing of the at least two supporting structures, so as to be suitable for supporting silicon rods of various specifications and sizes to be cut.

[0371] The roller driving source is used to drive each supporting roller in the supporting roller group to rotate, wherein the roller driving source can be, for example, a servo motor, and the servo motor can be associated with at least one supporting roller group through, for example, a chain (group) or a gear group.

[0372] In actual applications, when a silicon rod to be cut with a circular cross-section is placed in a horizontal state on the supporting structure of a crystal line detection device, the axis of the silicon rod to be cut is consistent with the transfer direction. After that, the roller driving source can drive each supporting roller in the supporting roller group to rotate so as to utilize the friction between the supporting roller and the silicon rod to be cut to drive the silicon rod to be cut to rotate, thereby completing the crystal line detection operation.

[0373] When using Figure 1 When the half-rod cutting device in the integrated cutting and grinding device for small-sized rectangular rods in the embodiment shown performs square cutting and half cutting operations, the specific process can be roughly as follows:

After the silicon rod is rotated 90°, the silicon rod is placed on the second silicon rod transfer device located at the second loading and unloading position. The silicon rod is placed horizontally and the axis of the silicon rod is consistent with the transfer direction.

[0379] Next, the position of the silicon rod is adjusted by using a centering adjustment mechanism in the silicon rod loading and unloading device so that the axis of the silicon rod corresponds to the predetermined center line.

[0381] Next, the edge skin clamp advance and retreat mechanism in the edge skin collapse prevention device is utilized, that is, the edge skin clamp is driven to retreat in the advance and retreat direction by the edge skin clamp advance and retreat mechanism, so that the edge skin clamped by the edge skin clamp can be retreated in the advance and retreat direction to drive the clamped edge skin to separate from the silicon rod body; the chuck driving mechanism in the edge skin clamp drives the chuck to move to release the clamped edge skin and make it fall on the edge skin bearing structure, and drives the edge skin bearing structure to drive the edge skin bearing structure and the edge skin carried by it to move from the second cutting position to the second loading and unloading position; the edge skin flipping mechanism is utilized to drive the edge skin bearing structure to flip; and the cut edge skin is unloaded by the edge skin unloading device.

[0383] Regarding the half-rod grinding equipment, the half-rod grinding equipment 2 of the present application includes: a grinding machine base, a grinding device, a chamfering device, and a half-rod transporting device.

[0384] The grinder seat is the main component of the half-rod grinding equipment and is used to provide a processing platform. In practical applications, the grinder seat 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 grinder seat can be used as the seat of different structures or components that perform processing operations in the half-rod grinding equipment, and the specific structure of the grinder seat can be changed based on different functional requirements or structural requirements. In some examples, the grinder seat includes a fixed structure or a limiting structure such as a base, a column, a frame, etc. for receiving different components in the half-rod grinding equipment, which are all grinder seats of the present application.

[0385] Meanwhile, in some examples, the grinding machine base may be an integrated base, and in some examples, the grinding machine base may include a plurality of independent bases.

[0386] The grinding machine base has a grinding processing platform, and the grinding processing platform can be divided into multiple functional areas according to the specific operation content of the half-rod grinding operation. For example, in some embodiments, the grinding processing platform includes a grinding area and a chamfering area. In some embodiments, the grinding processing platform includes a loading area, a grinding area, a chamfering area, and an unloading area. In some embodiments, the grinding processing platform includes a loading and unloading area, a grinding area, and a chamfering area. It should be noted that in each example provided in the present application, the functional area is defined by the travel path and range of the processing device at the functional area. For example, the grinding device of the half-rod grinding device is located at the grinding area, and the range of the grinding area is the range occupied by the grinding device in the process of completing the grinding operation; similarly, the chamfering device of the half-rod grinding device is located at the chamfering area, and the range of the chamfering area is the range occupied by the chamfering device in the process of completing the chamfering operation. The shape of the grinding processing platform can be determined according to the grinding machine base, or it can be determined jointly according to the processing needs of the grinding machine base and the grinding device and the chamfering device.

[0387] In some embodiments, the grinding platform is provided with a grinding area and a chamfering area. A grinding device is provided at the grinding area, and the grinding device includes at least one grinding tool. A chamfering device is provided at the chamfering area, and the chamfering device includes at least one chamfering tool. The grinding device is provided at the grinding area of ​​the grinding platform, and is used to perform a grinding operation on the side surface of the half rod located at the grinding area. The half rod has four side surfaces, and therefore, the grinding device is used to perform a grinding operation on the four side surfaces of the half rod.

[0388] In the present application, the half rod is placed horizontally at the grinding surface area of ​​the grinding processing platform. In order to ensure that the half rod can be stably placed at the grinding surface area, the half rod grinding device of the present application includes a first half rod clamping device.

[0389] The first half-rod clamping device is arranged at the grinding surface area and is used for clamping the end of the half-rod along the length direction.

[0390] The first half-rod clamping device is intended to clamp a half-rod.

[0391] In some embodiments, the first half-rod clamping device includes: a first load-bearing mount and a first half-rod clamp.

[0392] The first bearing mounting seat is arranged on the grinding machine seat. In some embodiments, the first bearing mounting seat is arranged on the grinding machine seat along the first direction for arranging the first half rod clamp.

[0394] The first clamping member driving mechanism is used to drive at least one of the at least one pair of first clamping members to move along the first direction to adjust the clamping distance between the pair of first clamping members. In some embodiments, two first clamping members of the pair of first clamping members are arranged opposite to each other along the first direction, and the first clamping member driving mechanism can drive at least one of the pair of first clamping members to move along the first direction to adjust the clamping distance between the pair of first clamping members arranged opposite to each other.

In order to ensure the stability of the first clamping member being able to move horizontally along the first direction, the number of the opening and closing guide rods may be multiple, for example, there are two opening and closing guide rods. Of course, the number of the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, drives one of the pair of first clamping members to move away from the other first clamping member along the opening and closing guide rod arranged in the first direction, or drives two of the pair of first clamping members to move away from each other along the opening and closing guide rod arranged in the first direction, thereby increasing the clamping distance between the two first clamping members, so as to release the clamped half rod. Among them, the telescopic air cylinder can also adopt a telescopic oil cylinder.
