Description

Technical Field

[0001] This invention relates to the field of processing high-hardness and brittle materials, and in particular to a method and system for processing edge skin. Background Technology

[0002] Silicon wafers are crucial materials for solar photovoltaic power generation. The manufacturing process of silicon wafers used in solar panels involves several steps: crystal pulling, cutting, squaring, polishing, and slicing. Crystal pulling involves chemically depositing cylindrical silicon rods in a crystal pulling furnace, with a maximum length of 11 meters. Cutting refers to cutting the pulled silicon rods into segments of varying lengths (100-950mm). Squaring involves cutting the cut silicon rods of different lengths into rectangular shapes. Polishing involves using a grinding wheel to polish the four surfaces of the squared rectangular monocrystalline silicon rods and rounding the four edges.

[0003] In the process of squaring crystal rods, in addition to producing usable cuboid crystal rods, four edge pieces with rounded surfaces and two side scraps (such as...) are also produced. Figure 1 (As shown). In traditional monocrystalline silicon rod processing, scraps such as edge pieces are usually treated as "waste," broken up, and recycled back into monocrystalline silicon rods. This process is complex and inefficient. To further improve the efficiency of silicon rod processing, existing crystal processing equipment can obtain usable silicon blocks by squaring the scraps again. After grinding and splicing the silicon blocks, they can be sliced ​​again to obtain usable wafer raw materials.

[0004] In the current technology, the reprocessing system for small and irregularly shaped silicon ingots such as edge skins is not perfect. It usually requires separate equipment for processing and production, and manual means to connect the various equipment and processes. This method has low automation, poor production efficiency, and high labor costs. Especially when it is necessary to perform full-process operations such as squaring, cutting, grinding and splicing of the edge skins, it is difficult for the various processes to cooperate in terms of efficiency, and the equipment cannot be automatically connected. Not only is the production capacity limited, but the quality of the finished product produced by silicon ingot reprocessing is also poor. Summary of the Invention

[0005] The purpose of this invention is to provide a method and system for processing edge skin, and to solve the problem in the prior art where the various processing steps cannot be automatically connected, resulting in low production efficiency and poor product quality. The specific technical solution is as follows:

[0006] One aspect of the present invention provides a method for processing edge skin, comprising:

[0007] Cut the two ends of the edge skin to obtain the arc-shaped middle material;

[0008] Cut the arc-shaped surface of the middle material at the top of the arc to obtain a long strip;

[0009] Long strips of material are cut into sections to obtain finished products;

[0010] Grinding is performed on all four sides of the finished material to obtain the material blocks to be assembled;

[0011] The material blocks are arranged into a block group and bonded and cured into a whole to form a material rod.

[0012] Furthermore, before cutting the two ends of the edge skin, the process also includes: pressing the two end faces of the edge skin to center the edge skin in the axial direction, while measuring the axial length of the edge skin.

[0013] Furthermore, before cutting the ends of the edge skin, the process includes: sliding support for the curved surface of the edge skin, squeezing the flat surface of the edge skin, allowing the curved surface of the edge skin to roll, leveling the flat surface of the edge skin, and clamping the curved surface and flat surface of the edge skin from top to bottom.

[0014] Furthermore, after clamping the curved and flat surfaces of the edge skin from the top and bottom, the process also includes: laterally clamping the two sharp corners of the edge skin end face to facilitate vertical cutting of the two ends of the edge skin and stably clamping the end material and the arc-top intermediate material obtained after cutting.

[0015] Furthermore, after cutting the ends of the edge skin, the process also includes: moving the end material so that the cut end material and the arc-shaped middle material form a gap, so that the cutting line can be moved out through the gap.

[0016] Furthermore, after cutting the ends of the edge skin, the process also includes:

[0017] The cut end material and the arc-top intermediate material are placed on the first conveying device;

[0018] When the material is moved to the feeding position of the middle material at the top of the cutting arc, the middle material at the top of the arc rises to disengage from the first conveying device.

[0019] When the material moves to the end point of the first transmission device, the end material falls off to detach from the first transmission device.

[0020] Furthermore, before cutting the arc-shaped surface of the arc-shaped intermediate material, the method further includes clamping the two sides of the arc-shaped intermediate material to facilitate transverse cutting of the arc-shaped end face of the arc-shaped intermediate material.

[0021] Furthermore, during the cutting process of the arc-shaped end face of the intermediate material at the top of the arc, the arc-shaped material obtained after cutting is simultaneously supported from one side of the arc-shaped surface.

[0022] Furthermore, after cutting the arc-shaped surface of the intermediate material at the top of the arc, the process also includes:

[0023] The long strip and the curved strip are rotated synchronously to the top of the second feeding conveyor, so that the curved strip is below the long strip;

[0024] Release the support for the curved material, allowing it to fall onto the second feeding conveyor.

[0025] After the curved material is removed, the clamping of the long strip is released, allowing the long strip to fall onto the second feeding conveyor.

[0026] Furthermore, after cutting the long strip of material, the process also includes:

[0027] Remove the finished material from the third cutting table;

[0028] Rotate the third cutting table to allow the cut scrap to slide off and detach from the third cutting table.

[0029] Furthermore, grinding operations are performed on the four sides of the finished material, including:

[0030] Place the finished material on the third clamping component and adjust its position so that the center of the finished material coincides with the clamping center of the third clamping component;

[0031] Rotate the third clamping assembly to the rough grinding station to rough grind the finished material;

[0032] Rotate the third clamping assembly to the fine grinding station to fine grind the finished material.

[0033] Furthermore, the process of coarse grinding and / or fine grinding of the finished material also includes:

[0034] The reference position for detecting the grinding wheel;

[0035] Move the grinding wheel toward the third clamping assembly;

[0036] Detect the actual position of the third clamping component;

[0037] The offset of the grinding wheel is calculated based on the reference position of the grinding wheel and the actual position of the third clamping assembly;

[0038] Adjust the relative position of the grinding wheel and the third clamping assembly so that the center position of the two grinding wheels coincides with the center position of the finished material.

[0039] Furthermore, the material blocks are arranged into material block groups, including:

[0040] The material blocks are fed in, and the material blocks are tested to see if they are qualified. The material blocks are then divided according to the test results.

[0041] The positions of the qualified material blocks are adjusted, and the adjusted material blocks are transferred to the stacking platform for discharging the material blocks.

[0042] Repeat the dispensing action until the number of material blocks reaches the preset requirement, forming a group of material blocks.

[0043] Furthermore, the positions of the qualified material blocks are adjusted, including:

[0044] Adjust the material block from a horizontal position to a vertical position;

[0045] Center and adjust the vertically placed material blocks;

[0046] Reduce the spacing between adjacent material blocks.

[0047] Furthermore, arranging the material blocks into a material block group and bonding and curing them together also includes: applying adhesive to the workpiece plate, moving the adhesive-coated workpiece plate to the curing station, moving the arranged material block group and placing it on the adhesive-coated workpiece plate, so that the material block group and the workpiece plate are bonded and cured together to form a material rod.

Figure 1 As shown in b), the cutting system provided by the invention is used to perform the square root operation 1c on the edge skin. After the square root operation, two end pieces, one arc-shaped piece and one long strip are obtained. The long strip is subjected to the truncation and cutting operation 1d to obtain multiple finished pieces. The finished pieces are subjected to the grinding operation to obtain the material block to be spliced ​​as shown in 1e. The multiple material blocks are spliced ​​and glued to obtain the material bar as shown in 1f.

[0127] like Figure 2 As shown, the processing system provided by the present invention specifically includes a cutting system A, a grinding system B, and a rod-jointing system C arranged in sequence. The following structural drawings provide a detailed description of the processing system provided by the present invention.

[0129] The cutting system provided by this invention can be used to cut edge strips, wherein the edge strip is a long strip structure with one side being an arc surface and the other side being a flat surface, making the end face of the edge strip arched. The specific cutting steps for cutting the edge strip are as follows: Figure 1 As shown, it specifically includes:

[0130] The first process: cut off the ends of the edge skin on both sides to form two end materials (first material) and one intermediate material with an arc-shaped surface on one side and three flat surfaces on the other side (first intermediate material);

[0131] The second process: cut the arc surface of the intermediate material at the top of the arc to form an arc-shaped material (second material) and a long strip material (second intermediate material);

[0132] The third step is to cut the long strip into multiple finished pieces of the same size and edge pieces (third material). The edge pieces are the scraps left after cutting, usually located at both ends of the long strip.

It can be understood that the first storage device 10 and the feeding and transfer device 20 are applicable not only to the cutting system A described above, but also to other types of cutting devices.

[0138] Furthermore, edge skins are generally placed in a curved or flat manner. The curved surface of the edge skin is not conducive to clamping, and when clamping the flat surface of the edge skin, the rolling of the curved surface will cause the flat surface of the edge skin to be unstable. Therefore, the existing transfer device cannot store and transfer the edge skin well. Based on the structural characteristics of the edge skin, the present invention designs a corresponding first storage device 10, a feeding and transfer device 20, and a leveling device that cooperates between the first storage device 10 and the feeding and transfer device 20. The first storage device 10, the feeding and transfer device 20, and the leveling device of the present invention will be described in detail below with reference to the accompanying drawings.

[0139] 1.1 First storage device 10

[0140] The first storage device 10 provided in this embodiment of the invention includes a transmission component and multiple sets of partition components 102 connected to the transmission component. The transmission component drives the partition components 102 to move along the transmission direction. One end of the partition component 102 is connected to the transmission component, and the other end extends away from the transmission component. The multiple sets of partition components 102 are arranged side by side along the extension direction of the transmission component, and a receiving interval is formed between two adjacent partition components 102. Each receiving space can hold one material.

[0141] In this embodiment of the invention, while stabilizing the position of the edge skin, the edge skin is placed between adjacent partition components 102 in a side-standing manner, so that the transmission component can deliver more edge skin at one time, increasing the number of edge skins that can be received in one transmission process and reducing the number of times manual loading is required.

[0142] Furthermore, the transmission assembly is a rotary transmission device 101, which includes rotary drive shafts disposed at both ends and rotary transmission components sleeved on the rotary drive shafts. At least one rotary drive shaft is equipped with a rotary drive device, which drives the rotary drive shaft to rotate, thereby causing the rotary transmission components to rotate along the rotary drive shafts at both ends. The rotary transmission device 101 causes each partition component 102 to reciprocate cyclically at the starting and ending ends of the transmission assembly.

[0143] In a specific embodiment of the present invention, the rotary transmission device 101 is a chain transmission device, the rotary transmission component is a chain, and the rotary drive shaft is a sprocket disposed at both ends of the chain transmission device. By driving one or two sprockets to rotate, the entire chain transmission device is driven to rotate. Optionally, the rotary transmission device 101 can also be a belt transmission device, the rotary transmission component is a belt, and the rotary drive shaft is a belt drive shaft disposed at both ends of the belt transmission device.

[0144] Furthermore, in an optional embodiment of the present invention, the partition components 102 are uniformly installed on the rotary transmission device 101, so that the upper partition components 102 move along the transmission direction, and the lower partition components 102 move in the opposite direction to the starting end of the rotary transmission device 101. Since only the upper edge material receiving space needs to be filled for the one-time feeding of the edge material, in another optional embodiment of the present invention, the partition components 102 are uniformly installed along a length greater than or equal to half the axial length of the rotary transmission device 101.

[0145] Furthermore, the partition component 102 of the present invention can be a lever. A protrusion 1021 for abutting the arc-shaped surface of the material is provided on one side of the lever away from the transmission component. The protrusion 1021 acts as a fulcrum to support the arc-shaped surface of the material and prevent the arc-shaped surface from rolling. Therefore, the material can be placed more stably on the partition component 102. During the process of the lever rotating laterally, the protrusion 1021 can prevent the edge arc-shaped surface from rolling on the lever, thereby preventing the edge from slipping off the lever.

[0146] In an optional embodiment of the present invention, the other side of the lever opposite to the protrusion 1021 is a smooth portion, which moves toward the transmission direction. The protrusion 1021 is provided at the end opposite to the transmission direction so that the edge arc surface moves toward the transmission direction.

[0147] Furthermore, to improve the stability of material transmission, a partition assembly 102 includes at least two levers, which are spaced apart perpendicular to the direction of movement of the partition assembly 102. When the rotary transmission device 101 of the transmission assembly is a chain drive, the transmission assembly includes at least two sets, which are spaced apart perpendicular to the transmission direction of the transmission assembly, and each chain drive has levers evenly installed, such that levers at the same position on at least two sets of transmission assemblies constitute a partition assembly 102. When the transmission assembly is a belt drive, at least two levers are arranged side by side on the transmission belt, and the at least two levers arranged side by side constitute a partition assembly 102.

[0148] Furthermore, the accompanying drawings show one side-standing method for the edge skin, in which the edge skin is placed horizontally. It can be understood that, to save horizontal transport space, the edge skin can also be transported vertically. In this case, the extension length of the partition assembly 102 needs to be appropriately increased according to the axial length of the edge skin. When the edge skin is transported vertically, the protrusion 1021 can be a roller structure. The roller structures at the front ends of the two parallel partition assemblies 102 are arranged adjacently to place the curved surface of the edge skin between the two adjacent rollers, preventing the edge skin from rolling sideways.

[0149] 1.2 Leveling device

[0150] The first material storage device 10 and the material feeding and transfer device 20 provided by this invention together constitute a leveling device for the edge skin. For example... Figures 5-6 As shown, the transmission terminal of the transmission component is also provided with a support component 103, which works in conjunction with the partition component 102 of the first storage device 10 and the pressure component of the feeding and transfer device 20 mentioned in the subsequent embodiment to achieve the leveling operation of the material, especially the edge skin.

[0151] Specifically, the supporting component 103 is provided with a leveling structure that can slide against the arc-shaped surface of the edge skin. This leveling structure can be a roller assembly arranged opposite to each other. The roller assembly lifts both sides of the arc-shaped surface of the edge skin, so that the edge skin can roll on the roller assembly to achieve leveling and adjustment.

[0152] Optionally, the leveling structure can also be a roller assembly arranged opposite to each other and a support platform located at the bottom of the roller assembly, with the roller assembly supporting both sides of the curved surface of the edge skin and the support platform supporting the bottom of the curved surface of the edge skin; or, the leveling structure can be a support block with a curved groove, the curved groove of the support block abutting against the curved surface of the edge skin, and the curved surface of the edge skin sliding in the curved groove to achieve leveling adjustment; or the leveling structure can be a semi-circular ring with a curved structure, the inner side of the semi-circular ring abutting against the curved surface of the edge skin.

[0153] Furthermore, the pressure component is positioned above the support component 103. The pressure component moves relative to the support component 103 to apply pressure to the edge skin on the leveling structure, causing the curved surface of the edge skin to slide relative to the leveling structure, thus adjusting the placement position of the edge skin. The pressure component applies pressure to the plane of the edge skin, making the edge skin plane flush with the lower surface of the pressure component, thereby adjusting the position of the curved surface of the edge skin on the leveling structure, thus achieving edge skin leveling. The detailed structure of the pressure component will be described in more detail in the subsequent section on the feeding and transfer device 20.

[0154] Furthermore, since the supporting component 103 is located at the transmission terminal of the first storage device 10, and the partition component 102 and the supporting component 103 are staggered, the partition component 102 can move relative to the supporting component 103, driving the edge skin to move onto the leveling structure of the supporting component 103, thereby realizing the transfer of the edge skin between the partition component 102 and the supporting component 103.

[0155] Specifically, when the rotary transmission device 101 drives the partition assembly 102 to rotate to the end of the rotary transmission device 101, the partition assembly 102 can rotate from the vertical direction to the horizontal direction, so that the edge skin on the partition assembly 102 remains on the support assembly 103. That is, when the partition assembly 102 falls below the support assembly 103, the support assembly 103 intercepts the edge skin on the partition assembly 102, and the support assembly 103 supports the arc-shaped surface of the edge skin.

[0156] In one specific embodiment of the present invention, the supporting component 103 is fixedly disposed at the feeding end, and the partition component 102 moves toward the supporting component 103. The partition component 102 slowly approaches the supporting component 103 by rotating downwards. When the partition component 102 moves below the supporting component 103, the supporting component 103 intercepts the edge material on its roller assembly. It can be understood that in an optional embodiment of the present invention, the relative movement between the partition component 102 and the supporting component 103 can also be such that the partition component 102 moves vertically downwards in a vertical transmission manner, while the supporting component 103 is fixed at a preset bottom position. When the partition component 102 moves below the supporting component 103, the supporting component 103 intercepts the edge material on its roller assembly. Correspondingly, the supporting component 103 can also achieve the function of intercepting the edge material through movement, which will not be elaborated here.

[0157] Furthermore, when the partition assembly 102 includes at least two sets of levers, the support assembly 103 is positioned between any two adjacent levers. In this case, there is no interference between the support assembly 103 and the levers.

[0158] In a specific embodiment of the present invention, two sets of levers are arranged side by side perpendicular to the transmission direction of the transmission component. A support component 103 is disposed at the end of the transmission component and correspondingly positioned with respect to the space between adjacent levers. The support component 103 is fixedly connected to the transmission support via a support bracket. Specifically, the support component 103 includes a support platform and a roller assembly on the support platform. The height of the support platform is lower than the transmission plane of the transmission component. Specifically, the support platform positions the support surface of the support component 103 within the vertical width of the rotary drive shaft, intercepting the edge material just before the lever reaches a horizontal position. This facilitates leveling the edge material under its own weight and prevents it from slipping off the lever. It is understood that the leveling device provided in this embodiment of the present invention can be applied to loading, unloading, and other edge material transfer scenarios.

[0159] 1.3, Material feeding and transfer device 20

[0160] like Figure 6 As shown, this embodiment of the invention also provides a feeding and transfer device 20 that works in conjunction with the first storage device 10. The feeding and transfer device 20 includes a transfer drive assembly and a gripping execution assembly disposed at the end of the transfer drive assembly. The gripping execution assembly includes a pressure assembly and a gripping assembly. The pressure assembly is retractably mounted on the gripping execution assembly. The pressure assembly extends out of the gripping execution assembly to compress the material to adjust its position. The transfer drive assembly drives the gripping assembly to grip and transfer the adjusted material. The pressure assembly cooperates with the support assembly 103 to adjust the placement position of the edge material.

[0161] Furthermore, the gripping component of the present invention is a suction cup component, which is used to pick up the material from a flat surface. The suction cup component consists of multiple suction cups spaced apart, and the pressure component is a pressure block component 205, which is disposed between any adjacent suction cups, wherein the pressure block component 205 is preferably disposed in the middle position of the gripping component. The lower surface of the pressure block component 205 is a flat surface, and by contacting and pressing down on the flat surface of the edge skin, the flat surface of the edge skin is adjusted to abut against the flat surface of the pressure block, thereby achieving leveling of the flat side of the edge skin.

[0162] It should be noted that the feeding and conveying device 20 provided by the present invention can not only convey edge skins, but also other materials that require adjustment of the gripping surface. In a specific embodiment of the present invention, the arc-shaped surface of the material is floating between adjacent rollers. During the process of the pressing block assembly 205 pressing down on the edge skin plane, the arc-shaped surface of the edge skin rolls between the two rollers to make the plane of the edge skin parallel to the lower surface of the pressing block assembly 205, thereby achieving the leveling of the edge skin.

[0163] Furthermore, the pressing block assembly 205 provided in this embodiment of the invention includes a pressing block and a pressing block driving device. The pressing block driving device is fixed on the gripping execution assembly. The driving end of the pressing block driving device is connected to the pressing block. The lower surface of the pressing block is a plane and parallel to the suction plane of the suction cup assembly.

[0164] Specifically, the pressing block driving device is an adjusting cylinder. The adjusting cylinder can drive the pressing block to move a short distance. Before the suction cup picks up the edge skin, the adjusting cylinder drives the pressing block to protrude from the suction surface of the suction cup to perform a leveling operation on the edge skin. After the leveling operation, the adjusting cylinder drives the pressing block to retract. At this time, the suction cup is controlled to move downward to pick up the material, which can more firmly and stably pick up the flat surface of the edge skin.

[0165] Furthermore, the transfer drive component provided in this embodiment of the invention includes a fixing component and a first transfer component. The fixing component fixes the entire transfer drive component to a preset feeding end, and the first transfer component drives the gripping execution component to move between the feeding end and the preset feeding station.

[0166] Specifically, the fixed component is a transfer bracket 201, which is fixed to the feeding end. The first transfer component includes a first rotating shaft 202, which is rotatably connected to the transfer bracket 201 and can drive the gripping execution component to rotate around the transfer bracket 201.

[0167] Furthermore, a first rotation drive assembly is fixed on the transfer bracket 201. This first rotation drive assembly includes a rotation drive motor and a drive gear, with the rotation drive motor driving the drive gear to rotate. A driven gear is fixed to the end of the first rotating shaft 202, meshing with the drive gear to achieve rotation of the first rotating shaft 202. Understandably, the transfer bracket 201 is positioned between the loading end and the loading station, and the rotation of the first rotating shaft 202 enables the gripping execution assembly at its end to rotate between the two stations.

[0168] Furthermore, the first transfer component also includes a longitudinally moving vertical shaft 203, which is located at the end of the first rotating shaft 202. The longitudinally moving vertical shaft 203 drives the gripping execution component to reciprocate in the longitudinal direction. The longitudinally moving vertical shaft 203 provides space for the gripping execution component to move longitudinally, allowing the gripping execution component to move up and down relative to the first rotating shaft 202, thereby driving the edge skin gripped by the gripping execution component at the end of the longitudinally moving vertical shaft 203 to move up and down.

[0169] Furthermore, the gripping execution component includes a gripping execution base plate 204, which is rotatably connected to the end of the longitudinally moving vertical shaft 203. In a specific embodiment of the present invention, multiple suction cups are evenly arranged on the axial side of the gripping execution base plate 204, and the axial midpoint of the gripping execution base plate 204 is connected to the end of the longitudinally moving vertical shaft 203. By controlling the rotation of the gripping execution base plate 204, the gripping or placement angle of the edge material can be adjusted. The gripping execution base plate 204, rotatably connected to the end of the first transfer component, can adapt to the picking and placing of materials at different angles, and can also adjust the angle of the material during the transfer process to avoid interference with other devices.

[0170] This invention comprises a material feeding system for edge skins using a first storage device 10 and a feeding and transfer device 20. The first storage device 10 allows the edge skins to be separated by a partition component 102 during transport, enabling them to be transported sideways. This increases the number of edge skins that can be handled in a single transport, reduces the number of manual reloading operations, saves labor costs, and improves the overall efficiency of the equipment. Utilizing the shape characteristics of the edge skins, the supporting component 103 intercepts the edge skins on the partition component 102, while the curved surface of the edge skin floats precisely between the rollers positioned opposite each other on the supporting component 103, facilitating leveling of the edge skins using their own weight. Before the feeding and transfer device 20 uses a gripping component to grip the material, it first compresses the material using a pressure component, making the gripping surface of the material fit more closely to the gripping component, thereby improving the stability of the material gripped by the feeding and transfer device 20.

[0171] 2. First cutting device 1

[0172] like Figures 7-13As shown, the first cutting device 1 provided in this embodiment of the invention specifically includes a first storage platform 11, a first cutting worktable 12, a first cutting head 13, and a first conveying device 14. The first storage platform 11 is located at the loading station of the first cutting device 1, the first cutting head 13 is located at the cutting station of the first cutting device 1, and the first conveying device 14 is located at the unloading station of the first cutting device 1. The first cutting worktable 12 is movably arranged and can move between the first storage platform 11 and the first cutting head 13 or between the first conveying device 14 and the first cutting head 13.

[0173] Specifically, the first cutting worktable 12 clamps the material on the first storage platform 11 and moves it to the first cutting head 13. The first cutting head 13 cuts the material on the first cutting worktable 12 along the cutting feed path. The first cutting worktable 12 drives the cut material to the first conveying device 14. The first conveying device 14 receives the cut material and diverts the cut material, for example, diverting the first intermediate material to the loading station of the second cutting device 2 and diverting the first material to the material collection device.

[0174] The structure of each part of the first cutting device 1 of the present invention will be further described in detail below with reference to the accompanying drawings.

[0175] 2.1 First storage platform 11

[0176] like Figure 8 As shown in the figure, the first storage platform 11 provided in this embodiment of the invention is located at the loading station on one side of the processing chamber of the first cutting device 1. Since the first cutting device 1 performs cutting operations on the edge skin through a cutting head with a cutting wire mesh, when the cutting wire mesh on the cutting head needs to be replaced, a worker needs to enter the processing chamber to complete the replacement operation. Traditional storage platforms are generally fixed at the loading station, requiring additional standing space in the processing chamber for workers to enter and perform cutting wire mesh replacement or other maintenance operations. This standing space is not needed when the equipment is operating normally, which increases the floor space occupied by the processing chamber and wastes space.

[0177] Therefore, this invention provides a space-saving processing workshop. The processing workshop is equipped with a waiting area, a clearance area, and a first storage platform 11. The first storage platform 11 includes a storage plate 111 and a storage plate driving device. The storage plate driving device drives the storage plate 111 to move between the waiting area and the clearance area. When the storage plate 111 moves to the waiting area, it can be used to store material, on which edge skin or other materials to be cut are placed for the subsequent first cutting table 12 to clamp the material. When the storage plate 111 moves to the clearance area, it is in a retracted state, creating a clearance space at the original waiting area. At this time, the storage plate 111 does not occupy the space of the processing workshop, thus making it more convenient for workers to enter the processing workshop to complete the maintenance operations.

[0178] It should be noted that the first storage platform 11 provided in this embodiment of the invention can be applied not only to the first cutting device 1, but also to the processing chamber of other cutting equipment as needed. The cutting station and the waiting material position are arranged opposite each other. When the processing chamber is in working condition, the cutting station can pick up the material on the first storage platform 11 for cutting and processing. The clearance position is set away from the cutting station. The cutting station can be moved to a position close to the clearance space so that when the processing chamber is in maintenance condition, workers can stand in the clearance space or maintenance equipment can be placed in the clearance space. Therefore, the cutting station close to the clearance space can be maintained.

[0179] Furthermore, the first storage platform 11 also includes a storage bracket 113. One end of the storage bracket 113 is fixed to the base of the processing chamber, and the other end is connected to the mounting platform 114. One end of the storage plate 111 is rotatably connected to the mounting platform 114, and the other end of the storage plate 111 is used for storing material. The storage plate driving device can drive the storage plate 111 to rotate around the mounting platform 114. The storage bracket 113 supports the storage plate 111 at a suitable height for the first cutting worktable 12 to clamp the edge skin or other materials.

[0180] Furthermore, the storage plate 111 includes a connecting bracket and a supporting bracket connected to each other. The supporting bracket is used for storing materials. One end of the connecting bracket is rotatably connected to the mounting platform 114, and the other end is connected to the middle part of the supporting bracket. The connecting bracket and the supporting bracket are connected at a preset angle so that one end of the supporting bracket is flush with the end of the connecting bracket away from the supporting bracket. As shown in the figure, in this invention, the flush alignment of one end of the supporting bracket with the end of the connecting bracket away from the supporting bracket ensures that when the storage plate 111 moves to the clearance position, the supporting bracket will not interfere with the side wall of the processing chamber. Moreover, the connection of the connecting bracket to the middle part of the supporting bracket is more conducive to maintaining the force balance of the supporting bracket, making the supporting bracket more stably support the edge skin.

[0181] Understandably, in order to ensure that the support bracket does not interfere with the side wall of the processing chamber, in an optional embodiment of the present invention, the connecting bracket may also be connected to one end of the support bracket, and when the connecting end of the connecting bracket and the support bracket moves to the clearance position, it is close to the side wall of the processing chamber.

[0182] Furthermore, a rotating mounting shaft (not shown in the drawings) is fixedly connected to the storage plate 111. The storage plate 111 is rotatably connected to the mounting platform 114 via the rotating mounting shaft. A rotating drive bracket is mounted on the rotating mounting shaft, and the end of the rotating drive bracket away from the rotating mounting shaft is connected to the storage plate driving device. In a preferred embodiment of the present invention, the rotating drive bracket and the storage plate 111 are located on opposite sides of the mounting platform 114, thereby preventing the storage plate driving device from interfering with the storage plate 111.

[0183] Furthermore, in an optional embodiment of the present invention, the storage plate driving device is a driving cylinder 112. One end of the driving cylinder 112 is connected to the storage support 113, and the movable end of the driving cylinder 112 is connected to the storage plate 111 so as to drive the storage plate 111 to move through the movable end of the driving cylinder 112.

[0184] Furthermore, the drive cylinder 112 provided in this embodiment of the invention can drive the storage plate 111 to move in a straight line to complete the movement between the waiting position and the avoidance position. In a more preferred embodiment, the storage plate 111 can also be driven to rotate to complete the movement between the waiting position and the avoidance position. This method can further reduce the footprint of the first storage platform 11.

[0185] Specifically, the drive cylinder 112 is movably connected to the storage bracket 113. The movable end of the drive cylinder 112 is connected to the storage plate 111 at the first connection point, which is the end of the drive bracket away from the rotating mounting shaft. The storage plate 111 is connected to the storage bracket 113 at the second connection point, which is the rotating mounting shaft. The first connection point and the second connection point are kept at a preset distance so that the storage plate 111 rotates around the second connection point as the center.

[0186] Furthermore, when the drive cylinder 112 extends, the rotating drive bracket drives the storage plate 111 to rotate outward around the rotational mounting axis to reach the storage position. When the drive cylinder 112 retracts, the rotating drive bracket drives the storage plate 111 to rotate inward around the rotational mounting axis to reach the clearance position. Alternatively, in an alternative embodiment of the present invention, the storage plate driving device can also be a rotary drive motor, which drives the storage plate 111 to rotate between the storage position and the clearance position.

[0187] Furthermore, in a specific embodiment of the present invention, the storage plate 111 is used to place the edge skin to be cut, and therefore, support blocks are arranged opposite each other on the storage plate 111 to support the material. For materials with curved surfaces, such as edge skin, the support blocks include oppositely arranged inclined blocks so that the oppositely arranged inclined blocks support the curved surface of the material.

[0188] It should be noted that the first storage platform 11, in addition to its application in the first cutting device 1, can also be used in other processing workshops. The processing workshop is equipped with a cutting head, which has detachable cutting tools. By controlling the rotation of the storage plate 111 between the storage position and the clearance position, a working space is provided for workers to disassemble the cutting tools. Alternatively, it can provide other maintenance and operation space for workers. Furthermore, the first storage platform 11 can be placed at the unloading station, etc., as needed, aiming to provide a processing workshop that saves overall floor space.

[0189] 2.2 First Cutting Worktable 12

[0190] like Figure 9 As shown, the first cutting worktable 12 provided in this embodiment of the invention is mainly used to cooperate with the first cutting head 13 to complete the cutting of edge materials. It can be understood that the first cutting worktable 12 provided in this embodiment of the invention can also be applied to the clamping and transfer operations of other materials with similar requirements, and this invention does not limit this application. For ease of description, in this embodiment of the invention, the direction in which the first gripper assembly on the first cutting worktable 12 is relatively arranged is defined as the first direction, the direction in which the clamping bracket 121 and the first support assembly 122 are relatively arranged is defined as the second direction, and the direction in which the first gripper assembly moves as a whole along the second translational slide rail 128 is defined as the third direction. (Refer to...) Figure 7 The first direction is the y-axis direction, the second direction is the z-axis direction, and the third direction is the x-axis direction.

[0191] Furthermore, the first cutting worktable 12 provided in this embodiment of the invention includes a translation drive assembly and a first clamping assembly. The translation drive assembly can drive the first clamping assembly to move as a whole, and thus can drive the first clamping assembly to transfer between any two of the cutting station, loading station and unloading station of the first cutting device 1.

[0192] Furthermore, the first clamping assembly includes two sets of first gripper assemblies disposed on the translation drive assembly. As shown in the figure, the first gripper assemblies are disposed opposite each other along a first direction. The translation drive assembly can drive the two sets of first gripper assemblies to move along the first direction to move closer to or further away from each other, thereby clamping both ends of the material along the axial direction.

[0193] Furthermore, the first gripper assembly includes a main gripper, which can open or retract along a second direction to grip the upper and lower sides of one end of the material's axial direction. The first gripper assembly also includes a secondary gripper 123, which is disposed beside the main gripper. The secondary grippers 123 on the two sets of first gripper assemblies are arranged opposite each other in a first direction and can open or retract along the first direction to grip both ends of the material's axial direction. This invention uses oppositely arranged main grippers to grip the arc-shaped surface and horizontal side surface of one end of the edge skin's axial direction, which can stabilize the edge skin's position. Combined with the cutting head cutting the horizontal side surface of the edge skin, compared to cutting from the end face of the edge skin, this significantly reduces the cutting feed distance and improves cutting efficiency.

[0194] Furthermore, when the secondary grippers 123 are configured as a set, they are located on one side of the main gripper, clamping the end face of the edge material and cooperating with the cutting head to complete the cutting of one side of the material. When the secondary grippers 123 are configured as two sets, they are located on both sides of the main gripper, with the two secondary grippers 123 on the same first gripper assembly clamping the end material on both sides of the edge material respectively. This is particularly suitable for cutting heads with double-layer cutting wire mesh. During the edge material cutting operation, the main gripper clamps the position of the arc-shaped middle material, and the secondary grippers 123 clamp the position of the end material (i.e., lateral clamping of the two sharp corners of the edge material end face), which facilitates vertical cutting of both ends of the edge material and stably clamps the cut end material and arc-shaped middle material. Therefore, it can effectively prevent the cut end material from falling off and improve the stability of equipment operation.

[0195] Furthermore, the main gripper includes a clamping bracket 121 and a first support assembly 122 disposed opposite to each other. The clamping bracket 121 and / or the first support assembly 122 are movable to allow the clamping bracket 121 and the first support assembly 122 to move closer to or further away from each other. The first support assembly 122 is provided with a sliding structure. The clamping bracket 121 and the first support assembly 122, which are close to each other, press the material onto the sliding structure, allowing the material to slide along the sliding structure to adjust its position. In a specific embodiment of the present invention, the clamping bracket 121 and the first support assembly 122 are disposed opposite to each other along a second direction. The first support assembly 122 supports the arcuate surface of the edge skin, allowing the arcuate surface of the edge skin to slide upwards and downwards on the sliding structure. The clamping bracket 121 clamps the horizontal side surface of the edge skin. When the clamping bracket 121 presses down on the horizontal side surface of the edge skin, the position of the arcuate surface of the edge skin on the sliding structure is adjusted so that the horizontal side surface of the edge skin remains horizontal.

[0196] In a specific embodiment of the present invention, the first support component 122 is disposed below, and the clamping bracket 121 is disposed above. The cutting head completes the cutting of the edge material from top to bottom. At this time, the cutting wire mesh cuts the horizontal side of the edge material, avoiding the phenomenon of slippage when cutting the curved side, thus improving the cutting stability. It can be understood that in the above embodiment, the first support component 122 can also be disposed above, the clamping bracket 121 can be disposed below, and the cutting head or cutting wire can complete the cutting of the edge material from bottom to top.

[0197] Furthermore, the sliding structure includes two sets of spaced roller assemblies, which are arranged opposite each other along a third direction, forming a support space for the material between them. The material abuts against the roller assemblies on both sides, allowing the material to slide between the roller assemblies. Specifically, the curved surface of the edge skin is placed on the oppositely arranged roller assemblies, so that the two sides of the curved surface of the edge skin are in symmetrical line contact with the roller assemblies, which is beneficial for the leveling and sliding of the edge skin on the first support assembly 122.

[0198] Furthermore, the clamping bracket 121 also includes a first side plate and a second side plate connected to each other. The first side plates on the two sets of first gripper assemblies can approach each other along a first direction and abut against the axial end face of the material to detect the axial length of the material. In a specific embodiment of the present invention, when the first cutting worktable 12 moves to the position of the first storage platform 11, the two first gripper assemblies first approach each other along the first direction, and the first side plates contact the axial ends of the material. While performing the centering operation on the material, the distance between the axial ends of the material, i.e., the axial length of the material, is detected.

[0199] Furthermore, the second side plate and the first support component 122 are respectively arranged to form the second clamping surface of the clamping bracket 121. The second clamping surface of the clamping bracket 121 clamps the horizontal side of the edge skin. The second clamping surface, together with the first support component 122, further ensures that the horizontal side of the edge skin is in a horizontal state, thereby improving the stability and cutting accuracy of the edge skin end material cutting.

[0200] Furthermore, the first gripper assembly also includes a first bracket 125 and a first translational slide plate 124 movably connected to the first bracket 125. A first support assembly 122 is connected to the first translational slide plate 124, and the first translational slide plate 124 drives the first support assembly 122 to reciprocate relative to the clamping bracket 121. Specifically, the first translational slide plate 124 drives the first support assembly 122 to reciprocate along a second direction, achieving clamping of the edge arc surface and the horizontal side surface. The first side plate of the clamping bracket 121 is fixedly connected to the first bracket 125, and the second side plate extends to a position opposite to the first support assembly 122.

[0201] In a specific embodiment of the present invention, the clamping bracket 121 itself is relatively fixed in the second direction. The first support component 122, driven by the first translational sliding plate 124, moves closer to or away from the second side plate of the clamping bracket 121 along the second direction. The first side plate is located at the outer end of the clamping bracket 121 in the first direction and can therefore abut against the end face of the edge. It can be understood that in an optional embodiment of the present invention, the first support component 122 can be fixedly installed, and the clamping bracket 121 can move towards the first support component 122, or both the clamping bracket 121 and the first support component 122 can be moved to move closer to or away from each other.

[0202] Furthermore, the secondary gripper 123 includes an end-piece clamping plate and an end-piece clamping plate driving assembly. In this invention, the end-piece clamping plate driving assembly can drive the end-piece clamping plate to move a short distance in three-dimensional space. Specifically, the end-piece clamping plate driving assembly drives the end-piece clamping plate to reciprocate along a first direction so that the two secondary grippers 123, which are oppositely arranged on the two sets of first gripper assemblies, move closer to or further away from each other along the first direction. The end-piece clamping plate driving assembly can also drive the end-piece clamping plate to move closer to or further away from the first support assembly 122 so that the end material held by the secondary gripper 123 is moved away from the first intermediate material held by the main gripper, facilitating the wire retraction of the cutting head. In addition, the end-piece clamping plate driving assembly can also drive the end-piece clamping plate to reciprocate along a second direction to adjust the clamping position of the secondary gripper 123.

[0203] In a specific embodiment of the present invention, each main gripper is provided with a secondary gripper 123 on both sides. The clamping bracket 121 and the first support component 122 of the main gripper clamp the middle part of one end of the material along the second direction, that is, the part that clamps the first intermediate material. The end material clamping plates of the secondary gripper 123 clamp the two sides of the end face of the material, that is, the end face position of the edge material. After the end material is cut, the end material clamping plates are controlled to move away from the main gripper along the third direction, which can provide the cutting head with retraction space, avoid the cutting head from performing secondary cutting on the edge material when retracting the wire, and further ensure the cutting accuracy of the edge material.

[0204] Furthermore, the first cutting worktable 12 also includes a first translational base plate 126, on which a first translational slide rail 127 is provided, and a first gripper assembly is slidably connected to the first translational slide rail 127. The first translational slide rail 127 extends along a first direction, and the first support 125 of the first gripper assembly is slidably connected to the first translational slide rail 127. A first synchronous drive assembly is also provided on the first translational base plate 126, which is connected to two opposing sets of first gripper assemblies to drive the two sets of first gripper assemblies to move synchronously relative to each other along the first direction, thereby achieving edge skin centering and clamping operations or edge skin axial length detection. The first synchronous drive assembly provided in this embodiment can be a synchronous gear drive structure as shown in the attached figures, or a synchronous ball screw drive structure; this invention does not limit the specific type of drive assembly.

[0205] Furthermore, the translation drive assembly mentioned in this embodiment of the invention also includes a second translation slide rail 128, and the first clamping assembly is slidably connected to the second translation slide rail 128. The translation drive assembly drives the first clamping assembly to reciprocate along the second translation slide rail 128. Specifically, the second translation slide rail 128 extends along a third direction, and the first translation base plate 126 is slidably connected to the second translation slide rail 128. The second translation drive assembly can drive the first translation base plate 126 to reciprocate along a third direction. The second translation drive assembly can be a ball screw or a gear rack structure, etc., and the invention is not limited thereto.

[0206] In a specific embodiment of the present invention, the second translation slide rail 128 includes two slide rails spaced apart along a first direction. The two sides of the first translation base plate 126 are slidably connected to the two slide rails respectively. The loading station, cutting station and unloading station of the first cutting device 1 are arranged along the extension direction of the second translation slide rail 128, specifically between the two slide rails of the second translation slide rail 128. The loading station is provided with a first storage platform 11, and the unloading station is provided with a first transmission device 14. When the first translation base plate 126 drives the first clamping assembly to move to the first storage platform 11, the two first gripper assemblies of the first clamping assembly are respectively located on both sides of the first storage platform 11 to clamp the two ends of the material on the first storage platform 11. When the first translation base plate 126 drives the first clamping assembly to move to the first transmission device 14, the two first gripper assemblies of the first clamping assembly are respectively located on both sides of the first transmission device 14 to place the cut material on the first transmission device 14.

[0207] Furthermore, the second translation slide rail 128 can be disposed on the second translation base plate, and then the second translation base plate can be disposed on the base of the first cutting device 1. Alternatively, the second translation slide rail 128 can be directly disposed on the base of the first cutting device 1. The present invention does not limit this.

[0208] The first cutting worktable 12 provided in this embodiment of the invention has a secondary gripper 123 arranged beside the main gripper of the first gripper assembly, so that the main gripper and the secondary gripper 123 can respectively clamp a portion of the cut material, preventing the cut material from falling onto the equipment base, reducing the occurrence of edge chipping during the cutting process, improving cutting quality, and improving the stability of equipment operation. Furthermore, the first support assembly 122 of the main gripper is provided with a sliding structure. While the clamping bracket 121 and the first support assembly 122 clamp the material, the material slides on the sliding structure to adjust its position, facilitating stable control of the material's state during cutting.

[0209] 2.3, First cutting head 13

[0210] like Figures 10 to 11As shown, the first cutting head 13 for edge trimming provided in this embodiment of the invention has a double-layer wire mesh structure. This double-layer wire mesh structure allows for two cutting operations to be completed in a single cutting feed, improving the cutting efficiency of the cutting head. Especially for short-distance repetitive cutting operations such as edge trimming or severance cutting, if only a single-layer wire mesh is used, the cutting head needs to frequently complete short-distance feed operations, which obviously increases the working time for one cut. Furthermore, setting up multiple layers of wire mesh over short distances does not affect the stability between different wire meshes in the cutting head and can also improve the working efficiency of the cutting head.

[0211] Furthermore, the first cutting head 13 provided in this embodiment of the invention includes a first head frame 131 and a plurality of shaft box assemblies disposed on the first head frame 131. A wire wheel mounting shaft 132 is disposed on the shaft box assembly. The wire wheel mounting shaft 132 is disposed perpendicular to the first head frame 131. Each wire wheel mounting shaft 132 includes at least two levels of wire wheel mounting positions extending in the axial direction. The wire wheel mounting positions located at the same level on different shaft box assemblies form a cutting wire mesh mounting plane after the wire wheel is installed. In a specific embodiment of the invention, a double-layer wire mesh is adopted. For other specific embodiments, a multi-layer wire mesh can also be adopted to realize the cutting operation.

[0212] Furthermore, the axle box assembly provided in this embodiment of the invention is an independent axle box assembly in which the reels rotate independently of each other, such as... Figure 11 As shown, the axle box assembly includes an axle box 167, inside which a first bearing 163 is installed. The outer ring of the first bearing 163 is fixedly connected to the axle box 167, and the inner ring of the first bearing 163 is fixedly connected to a first rotating shaft 161, so that the first rotating shaft 161 rotates with the first bearing 163 inside the axle box 167.

[0213] Furthermore, the first rotating shaft 161 is hollow, and its outer ring is fixedly connected to the second bearing 164. The inner ring of the second bearing 164 is fixedly connected to the second rotating shaft 162, allowing the second rotating shaft 162 to rotate within the first rotating shaft 161 along with the second bearing 164. In other words, the spool mounting shaft 132 consists of the first rotating shaft 161 and the second rotating shaft 162, which rotate independently. The front ends of the first rotating shaft 161 and the second rotating shaft 162 are respectively connected to spools, allowing the spools connected to the first rotating shaft 161 and the second rotating shaft 162 to rotate independently, ensuring that the two layers of cutting wire mesh do not interfere with each other.

[0214] Specifically, in this embodiment of the invention, a front end cover 165 is provided at the front end of the first rotating shaft 161, and a rear end cover 166 is provided at the rear end of the first rotating shaft 161. The front end cover 165 is used to fix and connect with the spool, forming a first-stage spool mounting position. The second rotating shaft 162 extends away from the end face of the first rotating shaft 161, and the second rotating shaft 162 forms a second-stage spool mounting position. Furthermore, as shown in the accompanying drawings, the diameter of the first rotating shaft 161 is larger than the diameter of the second rotating shaft 162, thus facilitating the disassembly and installation of the inner spool.

[0215] Furthermore, the second-stage wire sheave mounting slot has a preset axial length. By installing wire sheaves at different axial positions within the second-stage wire sheave mounting slot, the distance between the first and second wire mesh mounting planes can be adjusted. For example, the distance between the two layers of cut wire mesh can be adjusted by installing shims in front of the wire sheaves. Additionally, the second rotating shaft 162 can also be configured to add a layer of wire mesh mounting plane by progressively decreasing in size along the extension direction, or the distance between the first and second-stage cut wire mesh can be adjusted by using wire sheaves with different mounting inner diameters.

[0216] In this embodiment of the invention, each layer of wire mesh mounting plane includes a drive wheel, which drives the entire wire mesh to rotate to achieve the cutting operation. Specifically, at least one axle box assembly is connected to a first rotation drive device, which drives a first rotating shaft to rotate, causing the wire wheel mounted on the first rotating shaft to rotate. At least one axle box assembly is connected to a second rotation drive device, which drives a second rotating shaft to rotate, causing the wire wheel mounted on the second rotating shaft to rotate. In this embodiment of the invention, the first and second rotation drive devices can be mounted on the same axle box assembly or on different axle box assemblies; this is not a limitation of the invention.

[0217] Furthermore, each layer of wire mesh mounting plane also includes a tension wheel, which can adjust the tension of the wire mesh during cutting. Specifically, at least one axle box assembly is connected to the first machine head frame 131 via a tension adjusting device (not shown in the figures). The tension adjusting device includes a rocker arm rotatably connected to the first machine head frame 131. One end of the rocker arm is connected to the axle box assembly. The position of the axle box assembly is adjusted by adjusting the angle of the rocker arm on the first machine head frame 131. A counterweight is connected to the end of the rocker arm away from the axial assembly. The rocker arm can be rotated by the weight of the counterweight, thereby adjusting the angle of the rocker arm on the first machine head frame 131.

[0218] Furthermore, in a specific embodiment of the present invention, in addition to the above-mentioned independent shaft shaft box assembly, the multiple shaft box assembly may also include a common shaft shaft box assembly. The reel mounting shaft 132 of the common shaft shaft box assembly is a third rotating shaft. The third rotating shaft is rotatably connected to the common shaft shaft box assembly. Each reel mounted on the third rotating shaft rotates synchronously. The structure of the third rotating shaft is the same as that of the first rotating shaft and the second rotating shaft, and will not be described in detail in the present invention.

[0219] It should be noted that the rotation drive device for the thread reel in this embodiment of the invention can be installed on an independent shaft axle box assembly or on a shared shaft axle box assembly. When installed on the shared shaft axle box assembly, a rotating shaft drive device is provided at the rear end of the shared shaft axle box assembly. The rotating shaft drive device drives a third rotating shaft to rotate, thereby driving the thread reel installed on the third rotating shaft to rotate. Furthermore, the tension adjusting device can also be installed on the shared shaft axle box assembly. This embodiment of the invention does not limit the installation position of the tension adjusting device and the rotation drive device for the thread reel, as long as each cutting wire mesh has one drive wheel and one tension wheel.

[0220] Furthermore, the first head frame 131 is provided with a groove on one side of the cutting position. The groove provides clearance space for the cutting position, specifically to avoid the material to be cut or the first clamping component.

[0221] Furthermore, in an optional embodiment of the present invention, in two adjacent shaft box assemblies located on one side of the cutting position, the wire wheel mounting shaft 132 of one shaft box assembly is lower than the wire wheel mounting shaft 132 of the other shaft box assembly. At this time, the cutting position of the cutting wire mesh forms a certain angle with the cutting plane to facilitate wire feeding.

[0222] Furthermore, the first cutting head 13 also includes a head drive assembly, which drives the first head frame 131 to reciprocate along the cutting feed direction.

[0223] Specifically, the first cutting head 13 provided in this embodiment of the invention is a gantry structure, which includes a feed assembly 134, a side column assembly 135 and a crossbeam 136. One side of the first head frame 131 is slidably connected to the side column assembly 135. The feed assembly 134 is equipped with a corresponding drive guide assembly, which can drive the first head frame 131 to move up and down to complete the cutting feed.

[0224] It should be noted that the first cutting head 13 provided in this embodiment of the invention only needs to realize the reciprocating motion in the cutting feed direction to complete the cutting operation. The third cutting head 33 in the third cutting device 3 also needs to realize the axial motion along the third cutting worktable 34 in order to select the cutting position of the long strip. The specific structure of the third cutting head 33 will be described in detail in subsequent embodiments.

[0225] 2.4 First Transmission Device 14

[0226] like Figure 12 , Figure 13 As shown, the first conveying device 14 is installed at the unloading station of the first cutting device 1 to unload the arc-shaped intermediate material and the end material. Since the arc-shaped intermediate material and the end material have different functions in subsequent processes, the arc-shaped intermediate material needs to enter the next cutting process for arc-shaped surface cutting, while the end material needs to be collected together with some materials from other cutting processes. Therefore, how to quickly and efficiently convey two materials with completely different shapes and uses becomes a problem that needs to be solved.

[0227] Furthermore, the first transmission device 14 includes a first transmission component 144 and at least one support assembly connected to the first transmission component 144. The support assembly includes a first support 141 for supporting materials and a second support 142 located on the side of the first support 141. The first support 141 is provided with a groove portion that matches the bottom of the transmitted material. The first transmission component 144 drives the support assembly to move as a whole.

[0228] Specifically, when unloading the arc-top intermediate material and the end material, the first cutting worktable 12 clamps the arc-top intermediate material and the end material and moves them as a whole to above the first transmission device 14. At this time, the first translation slide plate 124 of the first clamping assembly drives the first support assembly 122 of the main gripper and the secondary gripper 123 to move downward as a whole, so that the arc-top intermediate material and the end material fall onto the support assembly, thus completing the material transfer between the first cutting worktable 12 and the first transmission device 14.

[0229] Furthermore, the first support platform 141 can be composed of a support block with a groove in the middle. Alternatively, it can be composed of two opposing support structures, with the height of the side of the two support structures closer to each other being lower than the height of the side further away from each other, so that the opposing support structures form a groove. Since the first support platform 141 needs to rotate at its end, to avoid the first support platform 141 being too wide and affecting its rotational flexibility on the first transmission assembly 144, a preferred embodiment of the present invention is that the first support platform 141 is composed of two opposing support structures.

[0230] Furthermore, the supporting structure can be wedge-shaped blocks, with the shorter sides of two wedge-shaped blocks arranged adjacently so that the inclined surfaces of the two opposing wedge-shaped blocks form a groove. The arc-shaped surface of the arc-top intermediate material is placed between the two wedge-shaped blocks, which can prevent the arc-top intermediate material from rolling on the first conveying device 14.

[0231] Furthermore, the second support platform 142 includes a flat block, the support height of which is lower than that of the first support platform 141 at the end of the flat block near the first support platform 141. Specifically, the horizontal plane of the flat block is lower than the highest point of the wedge block. When the arc-top intermediate material and the end material are placed together on the support platform assembly, the end material will naturally fall onto the second support platform 142, completing the separation of the end material and the arc-top intermediate material, facilitating subsequent operations. Understandably, the width of the first support platform 141 should be smaller than the width of the edge skin or the width of the arc-top intermediate material to facilitate the end material falling onto the second support platform 142.

[0232] Furthermore, the second support platform 142 also includes a baffle 143, which is connected to the end of the flat block away from the first support platform 141 and forms a preset angle with the horizontal plane of the flat block. Since the end material also contains a small arc surface, in order to prevent the end material from rolling off the second support platform 142, the present invention provides a baffle 143 structure to intercept the end material on the second support platform 142.

[0233] Furthermore, the first transmission component 144 includes a rotary transmission device with rotary shafts at both ends. At least one rotary shaft is equipped with a rotation drive device, which drives the rotary shafts to rotate, thereby causing the rotary transmission device to rotate as a whole. Specifically, the rotary transmission device is a chain drive device or a belt drive device. When it is a chain drive device, the rotary shaft is a rotary sprocket located at both ends of the chain drive device.

[0234] Furthermore, multiple platform assemblies can be provided on the first transmission component 144, with the multiple platform assemblies evenly installed on the first transmission component 144, so that the first transmission component 144 can simultaneously transmit multiple sets of materials. The platform assemblies located at the top move along the transmission direction, while the platform assemblies located at the bottom move in the opposite direction to the starting end of the rotary transmission device. This invention adopts a rotary transmission method, enabling the platform assemblies to circulate back and forth between the transmission start point and the transmission end point.

[0235] Furthermore, the first transmission device 14 provided in this embodiment of the invention also includes a lifting device 145. The lifting device 145 is disposed on the transmission path of the first transmission component 144. The lifting device 145 includes a lifting platform 146 and a lifting drive device. The lifting drive device drives the lifting platform 146 to protrude or retract from the transmission plane of the first transmission component 144. The function of the lifting device 145 is to lift the intermediate material at the arc top, serving as a waiting platform for the subsequent arc top material cutting device, which then clamps it. The remaining material remains on the first transmission device 14 and continues to move forward with it.

[0236] Furthermore, the lifting platform 146 is provided with a lifting support, the middle of which has a recessed structure to support materials with an arc-shaped surface. This recessed structure can be either opposing wedge blocks or opposing roller assemblies, supporting the arc-shaped surface of the material at the top of the arc while allowing the arc-shaped surface to slide on the lifting support to adjust its placement position; this invention does not limit the specific application of this feature.

[0237] Furthermore, the first transmission component 144 is provided with a second guide plate 147 and a material collection device at its transmission endpoint. The second guide plate 147 guides the first material into the material collection device. In a specific embodiment of the present invention, after the lifting device 145 lifts the intermediate material at the top of the arc, the end material remains on the first transmission component 144 and continues to move forward with the first transmission component 144. Since the end material is the first material in the current cutting process, it only needs to be transported to the material collection device.

[0238] Furthermore, in this embodiment of the invention, the first cutting device 1 also includes a first feeding and conveying device 15. The second guide plate 147 of the first conveying device 14 guides the end material onto the first feeding and conveying device 15, and then the first feeding and conveying device 15 guides the end material into the material collection device. This part of the structure will be described in detail in the subsequent feeding and conveying system section.

[0239] The first conveying device 14 provided in this embodiment of the invention uses a first support 141 and a groove on the first support 141 to support the bottom of one type of material produced after cutting, and uses a second support 142 on the side of the first support 141 to support another type of material produced after cutting, so as to achieve natural separation and simultaneous conveying of the two materials, simplify the material conveying operation process, and make the equipment structure more concise.

[0240] 2.5 Control method of the first cutting device 1

[0241] This invention also provides a control method for the first cutting device 1, the method specifically including:

[0242] S1. The first cutting workbench 12 clamps the material from the loading station and transfers it to the first cutting head 13.

[0243] S2. The first cutting head 13 cuts the material on the first cutting worktable 12 along the cutting feed path;

[0244] S3. The first cutting workbench 12 transfers the cut material to the first conveying device 14;

[0245] S4. The first conveying device 14 drives the cut material to move in order to complete the material feeding.

[0246] In a specific embodiment of the present invention, the cutting of the material on the first cutting worktable 12 along the cutting feed path specifically includes:

[0247] S21, the main gripper of the first gripper assembly clamps the middle part of one end of the material along the second direction, and the secondary gripper 123 of the first gripper assembly clamps the end face of the material along the first direction next to the main gripper.

[0248] In a specific embodiment of the present invention, the first clamping component clamps both ends of the edge skin along its axial direction, while the radial ends of the edge skin end face are clamped by the secondary jaws 123.

[0249] S22, The cutting wire mesh of the first cutting head 13 moves along the second direction between the main gripper and the auxiliary gripper 123 to cut the material.

[0250] In a specific embodiment of the present invention, the first cutting head 13 is a double wire mesh cutting head. At this time, the two wire meshes are respectively located at the end material cutting positions on both sides of the edge skin, so as to complete the cutting of the end material on both sides in one cutting feed.

[0251] Furthermore, after the edge material is cut, the first cutting head needs to be retracted first to transfer the arc-top middle material and the end material to the unloading station. Therefore, after the cutting wire mesh of the first cutting head 13 cuts the material by feeding along the second direction between the main gripper and the auxiliary gripper 123, the method further includes:

[0252] S23, the secondary gripper 123 moves away from the main gripper;

[0253] S24. The first cutting head 13 moves away from the first cutting worktable 12 in the second direction to perform the wire removal operation.

[0254] In a specific embodiment of the present invention, controlling the secondary gripper 123 to move away from the main gripper specifically means moving away from the main gripper along a third direction. At this time, the relatively arranged secondary gripper 123 can still stably hold the end material, so that a gap is formed between the end material and the arc-top intermediate material, allowing the first cutting head 13 to retract the wire.

[0255] Furthermore, the first conveying device 14 drives the cut material to move in order to complete the material unloading, specifically including:

[0256] S41. The first cutting worktable 12 moves the first gripper assembly to the first conveying device 14 and causes the cut material to fall onto the first conveying device 14.

[0257] In a specific embodiment of the present invention, when the first clamping assembly moves to the unloading station, the first clamping assembly clamps the arc-top intermediate material and the end material and moves them to the top of the first transmission device 14. At this time, the first translation slide plate 124 of the first clamping assembly drives the first support assembly 122 of the main gripper and the secondary gripper 123 to move downward as a whole, so that the arc-top intermediate material and the end material fall onto the support assembly, thus completing the material transfer between the first cutting workbench 12 and the first transmission device 14.

[0258] S42, the first transmission component 144 of the first transmission device 14 drives the entire support assembly on it to move along the transmission direction;

[0259] S43. When the first platform 141 supporting the first intermediate material moves to the lifting device 145 of the first transmission device 14, the lifting device 145 rises to lift the first intermediate material on the first platform 141.

[0260] S44, the first transmission component 144 of the first transmission device 14 continues to move along the transmission direction to drive the second platform 142 to the second guide plate 147 at the end of the transmission, and the second guide plate 147 guides the material on the second platform 142 to the preset material collection device.

[0261] In a specific embodiment of the present invention, the second support platform 142 carries the end material to the second guide plate 147, and the second guide plate 147 guides the end material to the first unloading conveyor 15, and finally enters the waste bin.

[0262] Furthermore, the control method of the first cutting device 1 in this embodiment of the invention also includes a feeding and clamping operation at the feeding station, specifically:

[0263] S01. The first cutting worktable 12 moves as a whole to the loading station, and the first gripper assembly moves synchronously relative to each other along the first direction to perform centering and / or measurement operations on the material through the clamping bracket 121 of the first gripper assembly.

[0264] In an optional embodiment of the invention, while the clamping bracket 121 performs a centering operation on the material, it can also measure the axial length of the material so as to know the size of the edge skin when performing subsequent cutting operations.

[0265] S02, the first gripper assembly moves synchronously to move the clamping bracket 121 away from the axial end face of the material, and the first support assembly 122 moves toward the clamping bracket 121 to lift the arc surface of the material and cooperate with the clamping bracket 121 to clamp the material.

[0266] In a specific embodiment of the present invention, since the first support component 122 is a roller assembly arranged opposite to each other, when the pressing bracket 121 presses down on the edge skin, the arc-shaped surface of the edge skin is adjusted between the roller assemblies to complete the leveling operation of the edge skin.

[0267] S03, the secondary gripper 123 of the first gripper assembly moves close to the end face of the material and clamps the end face of the material next to the main gripper.

[0268] In a specific embodiment of the present invention, after the main gripper grips the edge leather, the secondary gripper 123 moves close to the main gripper to cooperate with the main gripper in gripping the edge leather, thus completing the gripping operation of the edge leather.

[0269] The first cutting device 1 and its control method provided in this embodiment of the invention have the following advantages:

[0270] a. The first cutting worktable 12 drives the material to be transferred between the loading station, the first cutting head 13 and the first transmission device 14, which reduces the material transfer process and improves the overall cutting efficiency of the cutting device.

[0271] b. The two sets of first gripper assemblies of the first cutting worktable 12 are located on both sides of the first transmission device 14 and the first storage platform 11, so that the first cutting worktable 33 can control the two sets of first gripper assemblies to move to the position where they intersect with the first transmission device 14 and the first storage platform 11, and smoothly complete the transfer of materials.

[0272] c. A secondary gripper 123 is provided on the side of the main gripper of the first gripper assembly, so that the main gripper and the secondary gripper 123 can respectively hold the cut part of the material, prevent waste from falling onto the equipment base, reduce the occurrence of edge chipping during the cutting process, improve the cutting quality, and improve the stability of equipment operation.

[0273] d. The secondary gripper 123 can move away from the main gripper. By controlling the movement of the secondary gripper 123 away from the main gripper, it is convenient to retract the cutting head.

[0274] e. The first support component 122 is provided with a sliding structure. While clamping the material, the clamping bracket 121 and the first support component 122 allow the material to slide on the sliding structure to adjust the position of the material, so as to stabilize and control the state of the material when cutting it.

[0275] f. The first cutting head 13 of the double-layer wire mesh can cut both sides of the material at the same time, which improves the cutting efficiency of the cutting head.

[0276] g. The first platform 141 of the first conveying device 14 and the groove on the first platform 141 stably support the bottom of one material, and the second platform 142 on the side of the first platform 141 supports another material that has fallen, so as to achieve the separation and simultaneous conveying of the two materials.

[0277] 3. Second cutting device 2

[0278] like Figures 14-17 As shown, the second cutting device 2 provided in this embodiment of the invention specifically includes a second cutting worktable, a second cutting head 23, and a second unloading and conveying device 24.

[0279] The second cutting worktable includes a feed drive assembly 21 and a second clamping device 22. The feed drive assembly 21 drives the second clamping device 22 to move back and forth, and the second clamping device 22 can rotate relative to the feed drive assembly 21. The second cutting head 23 cuts the material clamped on the second clamping device 22, and the second unloading and conveying device 24 receives the cut material.

[0280] The second cutting worktable of the present invention cooperates with the second cutting head 23 and the second unloading and conveying device 24. While the second clamping device 22 moves along the feed direction, the cutting and unloading of materials are completed by controlling the rotation position of the second clamping device 22, reducing the operation steps of transferring materials and improving the cutting efficiency while increasing the space utilization of the equipment. The second cutting device 2 provided in the embodiment of the present invention will be further described in detail below with reference to the accompanying drawings.

[0281] 3.1 Second Cutting Worktable

[0282] In a specific embodiment of the present invention, the second cutting device 2 serves as an edge-skin arc-top material cutting device. It needs to clamp the arc-top intermediate material at the lower end of the edge-skin end material cutting device. Specifically, when the lifting device 145 of the first transmission device 14 is raised, it clamps the arc-top intermediate material on the lifting device 145. Therefore, the lifting device 145 serves as the second waiting platform of the second cutting device 2.

[0283] like Figures 14-16 As shown, the second cutting worktable provided in this embodiment of the invention includes a feed drive assembly 21 and a second clamping device 22. A loading station and / or unloading station are located near the feed drive assembly 21. The feed drive assembly 21 drives the second clamping device 22 to reciprocate between the loading station and the cutting station, and / or drives the second clamping device 22 to reciprocate between the unloading station and the cutting station. The second clamping device 22 is rotatably mounted on the feed drive assembly 21 to rotate between a cutting angle and a transfer angle. The cutting angle can be coordinated with the cutting station to cut the material, and the transfer angle can be coordinated with the loading station and / or the unloading station to transfer the material. It is understood that the transfer angle includes a pick-up angle and an unloading angle. At the pick-up angle, the second clamping device 22 cooperates with the second waiting platform to clamp the material; at the unloading angle, the second clamping device 22 cooperates with the second unloading conveyor 24 to complete the unloading.

[0284] Furthermore, the second clamping device 22 includes a clamping base 222 and a second clamping component disposed on the clamping base 222. The clamping base 222 is rotatably connected to the feed drive component 21, so that the second clamping component is rotated by controlling the rotation of the clamping base 222. During the rotation of the second clamping component with the clamping base 222, the orientation of the second clamping component is changed, thereby adapting to the directional layout of different devices such as the second waiting table, the second cutting head 23, and the second unloading conveying device 24. In addition, the feed drive component 21 drives the clamping base 222 to reciprocate along the cutting feed direction, thereby driving the second clamping component to move between different devices such as the second waiting table, the second cutting head 23, and the second unloading conveying device 24. That is, in the specific embodiment of the present invention, the cutting station, loading station, and unloading station of the second cutting device 2 are all set on the feed path of the second clamping device 22, making the overall structure of the equipment compact and the space utilization rate high.

[0285] In a specific embodiment of the present invention, the second waiting platform is disposed at one end of the feed drive assembly 21. After the clamping base 222 moves along the feed drive path to the position of the second waiting platform, the clamping base 222 drives the second clamping assembly to rotate to a position opposite to the second waiting platform, clamping the arc-shaped intermediate material on the second waiting platform. Then, the clamping base 222 is controlled to rotate to a position opposite to the second cutting head 23, and the arc-shaped intermediate material is cut along the cutting feed direction.

[0286] Furthermore, the feed drive assembly 21 includes a feed frame 211 and a transfer frame 212 slidably connected to the feed frame 211. A first rotating frame 221 is provided on the transfer frame 212, and a clamping base 222 is rotatably connected to the first rotating frame 221. The transfer frame 212 can reciprocate on the feed frame 211 to drive the clamping base 222 to reciprocate between the loading station and the cutting station, and / or reciprocate between the unloading station and the cutting station. By controlling the clamping base 222 to rotate on the first rotating frame 221, the second clamping assembly on the clamping base 222 is driven to rotate between different angles.

[0287] In a specific embodiment of the feed drive structure, this invention employs a ball screw. A screw extending along the cutting feed direction is mounted on the feed frame 211. An adapter frame 212 is connected to the screw via bolt assemblies. A drive motor rotates the screw, causing the adapter frame 212 to reciprocate along the screw, thus achieving the reciprocating motion of the adapter frame 212 in the cutting feed direction. For rotary drive, this invention uses a rotary drive motor to drive the clamping base 222 to rotate on the first rotary frame 221. It is understood that in practical applications, other drive methods can also be used to complete the feed drive and rotary drive; therefore, the above specific embodiments are not intended to limit the drive method in the embodiments of this invention.

[0288] Furthermore, in a specific embodiment of the present invention, the second clamping device 22 includes a second clamping component disposed on both sides of the clamping base 222. When the clamping base 222 is rotated to a direction perpendicular to the second cutting head 23, the arc-top intermediate material clamped on both sides of the clamping base 222 is cut simultaneously, thereby improving the cutting efficiency of the system.

[0289] Furthermore, the second clamping component on the second clamping device 22 includes a clamping reference surface and clamping devices 223 disposed on both sides of the clamping reference surface. The clamping reference surface abuts against the material, and the clamping devices 223 on both sides of the clamping reference surface move closer or further away from each other to clamp the opposite side of the material. A material support device 224 is disposed laterally on the clamping device 223. Specifically, the material support device 224 is disposed laterally on the clamping device 223 along the axial direction of the second clamping component. The material support device 224 includes a material support drive component and a material support jaw. The material support drive component drives the material support jaw to move to a position opposite to the clamping reference surface to clamp the bottom surface of the material. In a specific embodiment of the present invention, the clamping reference surface is one side of the clamping base 222.

[0290] Specifically, when cutting the material in the middle of the arc top, the second cutting head 23 cuts the material outside the clamping surface of the clamping device 223. During the cutting process, after the cutting line passes the material support device 224, the material support drive assembly drives the material support claws to extend to the outside of the clamping surface of the clamping device 223 to clamp the material. This not only ensures the stable cutting process but also effectively prevents the arc-shaped material from collapsing during the cutting process, thus improving the cutting quality.

[0291] Furthermore, the clamping device 223 includes a clamping drive assembly and clamping jaws. The clamping drive assemblies of the two clamping devices drive the two clamping jaws to move closer or further apart to clamp or release the material. In a specific embodiment of the present invention, the clamping drive assembly drives the two clamping jaws to move closer or further apart along the planes opposite sides of the material at the apex of the arc, clamping or releasing it.

[0292] Furthermore, the material-supporting gripper includes a first gripper 225 and a second gripper 226 connected to each other. The first gripper 225 is connected to the material-supporting drive assembly, and the second gripper 226 extends to a position opposite to the clamping reference surface to clamp the bottom surface of the material. The material-supporting drive assembly includes a material-supporting rotation drive assembly, which drives the material-supporting gripper to rotate outwards from the clamping reference surface. Additionally, the material-supporting drive assembly includes a clamping drive assembly, which clamps the material by driving the second gripper closer to or away from the clamping reference surface. Specifically, the clamping drive assembly can clamp the material by driving the relatively positioned material-supporting grippers to move relative to each other, or by driving the second gripper 226 to move closer to the bottom surface of the material.

[0293] Furthermore, since the axial length of the material at the top of the arc is relatively long, in a specific embodiment of the present invention, the clamping device 223 includes multiple sets, and the multiple sets of clamping devices 223 are arranged sequentially along the axial direction of the second clamping assembly. Correspondingly, the material-supporting device 224 also includes multiple sets, and the multiple sets of material-supporting devices 224 are arranged sequentially along the axial direction of the second clamping assembly. In a preferred embodiment, the multiple sets of clamping devices 223 and the multiple sets of material-supporting devices 224 are arranged sequentially at intervals along the axial direction of the clamping reference surface. The material-supporting device 224 in the present invention can be arranged opposite to the clamping device 223, or it can be arranged only on one side to ensure clamping of the arc-shaped material.

[0294] Furthermore, the second clamping assembly also includes a positioning plate, which is disposed on the clamping reference surface of the clamping base 222 and located between the clamping devices 223 disposed opposite to each other. In a specific embodiment of the present invention, when the second clamping assembly clamps the arc-shaped intermediate material, the positioning plate abuts against the horizontal side of the arc-shaped intermediate material, which can ensure the position of the arc-shaped intermediate material on the second clamping assembly and control the cutting accuracy when cutting the arc-shaped material.

[0295] The second cutting workbench provided in this embodiment of the invention, together with the second cutting head 23, can simultaneously cut the intermediate material of two arc tops, which improves the cutting efficiency of the equipment. In order to avoid the arc material from falling off during the cutting process, a material support device 224 is used to clamp the arc material, which improves the cutting quality and the operational stability of the equipment.

[0296] 3.2, Second cutting head 23

[0297] like Figure 17 As shown, the second cutting head 23 provided in this embodiment of the invention includes a second head frame, which includes a first head bracket 231 and a second head bracket 232 that are separately disposed. A feed space is formed between the first head bracket 231 and the second head bracket 232. At least one wire wheel is provided on both the first head bracket 231 and the second head bracket 232. The wire wheels on the second head frame form a wire mesh mounting plane for mounting the cutting wire mesh. The cutting wire mesh is hung on the wire wheels to form a cutting wire mesh. The cutting position of the cutting wire mesh is located between the first head bracket 231 and the second head bracket 232. In this embodiment of the invention, since the first head bracket 231 and the second head bracket 232 are separately disposed, the cutting wire located between the second head frames will not be blocked by the second head frames. When the cutting wire mesh between the second head frames is used as the cutting position of the cutting head, the position of the cutting head will not affect the installation position of the wire wheels or the installation position of the second clamping device 22. The installation and layout of other devices in the equipment are more flexible and reasonable, improving the overall rationality of the equipment layout.

[0298] Furthermore, in a preferred embodiment of the present invention, the second cutting head 23 includes two sets of second head frames that are separately arranged. The two sets of second head frames are arranged opposite each other to form two opposite wire mesh mounting planes, as shown in the figure. The second head frames of the second cutting head 23 provided in the embodiment of the present invention are arranged on both sides of the feed frame 211, so that a cavity is formed between the two second head frames. The clamping base 222 moves in the cavity between the two second head frames. When the clamping base 222 rotates to a position perpendicular to the second head frames, it simultaneously cuts the arc-shaped intermediate material clamped on both sides of the clamping base 222, thereby improving the cutting efficiency.

[0299] Furthermore, in a specific embodiment of the present invention, the wire reels are located on both sides of the two sets of second head frames, so that the second head frames are positioned between the two wire mesh mounting planes. Installing the wire reels on both sides of the two second head frames provides space for worker maintenance, which is more conducive to equipment maintenance.

[0300] Furthermore, in a specific embodiment of the present invention, the second cutting head 23 is fixed on the cutting feed path, while the second clamping components on both sides of the clamping base 222 move relative to the second cutting head 23 along the cutting feed direction with the feed frame 211. Therefore, the first head support 231 and the second head support 232 of the second head frame are both fixedly arranged. Specifically, the first head support 231 is fixed on the upper side of the feed frame 211, and the second head support 232 is fixed on the base. By fixing the first head support 231 and the second head support 232 in a preset position, the overall mechanical stability of the second head frame is ensured while the first head support 231 and the second head support 232 are separated.

[0301] Furthermore, in this embodiment of the invention, the wire spool is mounted on the second head frame via a wire spool mounting shaft. The position of the wire spool on the wire spool mounting shaft is adjustable to adjust the distance between the wire mesh mounting plane and the second head frame. The cutting thickness of the arc-shaped material in the arc-shaped middle material can be adjusted by adjusting the position of the wire spools on both sides on the wire spool mounting shaft.

[0302] In a specific embodiment of the present invention, two thread wheels are provided on both the first head support 231 and the second head support 232, forming a wire mesh mounting plane with four thread wheels. Each thread wheel includes at least one drive thread wheel. By controlling the rotation of the drive thread wheel, the cutting wire mesh on the wire mesh mounting plane is driven to rotate. Specifically, a thread wheel driving device is provided on the first head support 231 or the second head support 232. The thread wheel driving device is connected to a thread wheel to drive the thread wheel to rotate to form a drive thread wheel. The drive thread wheel drives the cutting wire mesh mounted on each thread wheel to rotate as a whole.

[0303] Accordingly, each reel also includes at least one tension reel. The tension of the cut wire mesh on the wire mesh mounting plane is adjusted by adjusting the position of the tension reel. Specifically, a tension adjustment mechanism is provided on the first head support 231 or the second head support 232. The tension adjustment mechanism is connected to a reel to adjust the position of the reel on the head frame, thereby changing the tension of the cut wire mesh. The tension adjustment mechanism includes a rocker arm, which is rotatably connected to the head frame. One end of the rocker arm is connected to the reel. The position of the reel on the head frame is adjusted by adjusting the angle of the rocker arm. The specific structure of the reel is described in detail in the prior art.

[0304] In a specific embodiment of the present invention, the cutting of the arc-top intermediate material is achieved by fixing the second cutting head 23 and moving the second clamping assembly along the cutting feed direction. It can be understood that, as an optional embodiment, the cutting of the arc-top intermediate material can also be achieved by setting both the first cutting head support 231 and the second cutting head support 232 to reciprocate along the cutting feed direction. In this case, the first cutting head support 231 and the second cutting head support 232 are slidably connected to the corresponding feed slide rails. By ensuring the synchronous operation of the first cutting head support 231 and the second cutting head support 232 on the feed slide rails, the stability of the cutting wire mesh is guaranteed.

[0305] Furthermore, in addition to completing the cutting operation of the arc-top intermediate material in the specific embodiment, the second cutting device 2 provided in this embodiment is also applicable to the cutting of other similar materials. Therefore, the cutting of the arc-top intermediate material is not used as a basis for limiting the protection scope of the second cutting device 2 of this invention.

[0306] 3.3 Second feeding conveyor device 24

[0307] Reference Figure 4 and Figure 23 In a specific embodiment of the present invention, the second feeding conveyor 24 is disposed on the base between the feed frames 211, and the second feeding conveyor 24 is located between two opposing second head frames. When the second clamping assembly on the clamping base 222 rotates to a position opposite to the second feeding conveyor 24, both the arc-shaped material and the long strip material on the second clamping assembly are fed onto the second feeding conveyor 24. Furthermore, the second feeding conveyor 24 extends to the loading station of the third cutting device 3 in this embodiment of the present invention, facilitating loading by the third cutting device 3. The second feeding conveyor 24 is a conveyor belt structure; by controlling the rotation of the conveyor belt, the material on the conveyor belt moves along the feeding conveyor direction.

[0308] In a specific embodiment of the present invention, the feeding frame 211 consists of two opposing frames, the adapter frame 212 is mounted above the space between the two frames, and the second unloading conveyor device 24 is located below the space between the two frames. The front ends of the two frames are equipped with loading devices, and the rear ends of the two frames are equipped with second cutting heads 23. That is, the loading, cutting, and unloading operations of the second cutting device 2 are all completed within the space between the two frames, resulting in a compact system with high space utilization.

[0309] 3.4 Control method of the second cutting device 2

[0310] This invention also provides a control method for the second cutting device 2, which specifically includes:

[0311] S1. After the second clamping device 22 clamps the material, it rotates to a cutting angle that matches the second cutting head 23;

[0312] S2. The second clamping device 22 moves along the feed path to cooperate with the second cutting head 23 to achieve material cutting;

[0313] S3. After the material is cut, the second clamping device 22 rotates to the feeding angle that matches the second feeding conveying device 24 to complete the feeding.

[0314] In a specific embodiment of the present invention, the second clamping device 22 includes a second clamping assembly, which includes a clamping device 223 and a material support device 224. The second clamping device 22 moves along the feed path to cooperate with the second cutting head 23 to achieve material cutting, specifically including:

[0315] S21, The clamping device 223 of the second clamping assembly clamps the material;

[0316] S22, the second clamping device 22 drives the second clamping assembly to move along the feed path, so that the second cutting head 23 cuts the material outside the clamping surface of the clamping device 223.

[0317] In a specific embodiment of the present invention, the second cutting head 23 cuts the arc-shaped bottom of the arc-shaped middle material to obtain a long strip and an arc-shaped material, wherein the clamping device 223 clamps the long strip and provides a wire inlet space for the cutting wire mesh.

[0318] S23. After the cutting surface of the second cutting head 23 passes the material support device 224, the material support drive assembly of the material support device 224 drives the material support claws to extend so as to hold the material that has been cut off.

[0319] In a specific embodiment of the present invention, to prevent the curved material from falling, after the cutting surface of the second cutting head 23 passes through the material support device 224, that is, after the cutting line on the front side of the second cutting head 23 passes through the material support device 224, the material support gripper is controlled to extend, thus preventing the cutting line from cutting into the material support gripper and preventing the curved material from falling. The cutting surface of the second cutting head 23 is the cutting line between the first head support 231 and the second head support 232, near the loading station.

[0320] Furthermore, embodiments of the present invention also include a material feeding operation, specifically comprising:

[0321] S31. After the cutting is completed, the second clamping device 22 drives the second clamping assembly to rotate to a position opposite to the second unloading conveying device 24;

[0322] S32, Control the material support claw to retract so that the material held by the material support claw falls onto the second feeding conveyor 24;

[0323] S33, control the clamping device 223 to open so that the material held by the clamping device 223 falls onto the second feeding conveyor 24.

[0324] In a specific embodiment of the present invention, the second feeding conveyor 24 is a conveyor belt. After the clamping base 222 drives the second clamping component on one side toward the second feeding conveyor 24, the material-supporting jaws are first controlled to retract, and the arc-shaped material falls onto the second feeding conveyor 24. After the second feeding conveyor 24 moves a certain distance, the clamping device 223 is controlled to open, and the cut strip material falls onto the second feeding conveyor 24. At this time, the clamping base 222 is controlled to drive the second clamping component on the other side toward the second feeding conveyor 24, completing the feeding of the arc-shaped material and the strip material on the other side. The second feeding conveyor 24 continues to move forward, and the first transfer device on the cutting device completes the classification operation of different materials.

[0325] The second cutting device 2 and its control method provided in this embodiment of the invention have the following advantages:

[0326] a. The second cutting worktable cooperates with the second cutting head 23 and the second unloading and conveying device 24. While the second clamping device 22 moves along the feed direction, the cutting and unloading of materials are completed by controlling the angle of the second clamping device 22. This reduces the operation steps of transferring materials and improves the cutting efficiency while increasing the space utilization of the equipment.

[0327] b. By simultaneously installing second clamping components on both sides of the clamping base 222 and setting two sets of cutting wire mesh, two materials can be cut at the same time, improving cutting efficiency;

[0328] c. The second waiting platform is set on one side of the feed frame so that the material on the second waiting platform can be clamped by the second clamping component on the clamping base. No other clamping device is needed to connect the material for feeding, which further improves the cutting efficiency.

[0329] d. The material to be cut is clamped by the clamping device 223. During the cutting process, the material support drive assembly drives the material support jaws to clamp the material to be cut off. This not only avoids the cutting tool during the cutting process and ensures the stability of the cutting, but also effectively prevents the material to be cut off from falling off during the cutting process and improves the cutting quality.

[0330] e. The second head frame is composed of a first head support 231 and a second head support 232 that are separately set up, so that a feed space is formed between the first head support 231 and the second head support 232. The cutting position of the wire mesh is located between the first head support 231 and the second head support 232. Therefore, other devices can pass through the feed space through the second head frame, making the installation and layout of other devices in the equipment more flexible and reasonable.

[0331] f. The reel is positioned on the outside of the two second head frames to facilitate maintenance and reel replacement during repairs.

[0332] 4. Third cutting device 3

[0333] like Figures 18-22 As shown, the third cutting device 3 provided in this embodiment of the invention specifically includes a transfer device 31, a third storage platform 32, a third cutting head 33, a third cutting worktable 34, a third unloading conveyor 35, and a finished product unloading conveyor 36. The third unloading conveyor 35 and the finished product unloading conveyor 36 are disposed to the side of the third cutting worktable 34. The third cutting head 33 is disposed perpendicular to the axial direction of the third cutting worktable 34 and is used to cut the second intermediate material on the third cutting head 33 to obtain multiple small pieces of finished material. The transfer device 31 is movably disposed between the third cutting worktable 34 and the finished product unloading conveyor 36, and can clamp the cut finished material and transfer it to the finished product unloading conveyor 36. The third cutting worktable 34 can rotate toward the third unloading conveyor 35. When it rotates to a position close to the third unloading conveyor 35, the cut waste material slides onto the third unloading conveyor 35. Furthermore, it should be noted that in this embodiment of the invention, the finished material feeding and conveying device 36 is also referred to as the first conveying device of the third cutting device 3, and the third feeding and conveying device 35 is also referred to as the second conveying device of the third cutting device 3. The third cutting device 3 provided in this embodiment of the invention will now be described in detail with reference to the accompanying drawings.

[0334] 4.1 Transfer device 31

[0335] like Figure 19 As shown, the transfer device 31 provided in this embodiment of the invention specifically includes a three-dimensional driving component 311 and a clamping bracket 312 disposed at the end of the three-dimensional driving component 311. The end of the clamping bracket 312 is provided with multiple grippers. Each gripper can cooperate to clamp a whole piece of material or clamp a small piece of material after the cutting operation. Specifically, it can be used to cooperate to clamp long strips and curved materials, or to clamp the finished material after cutting.

[0336] Furthermore, the three-dimensional driving component 311 specifically includes a first-direction crossbeam arranged opposite to each other, a second-direction longitudinal beam mounted on the first-direction crossbeam, and a third-direction vertical beam mounted on the second-direction longitudinal beam. The second-direction longitudinal beam reciprocates along the first direction on the first-direction crossbeam, and the third-direction vertical beam reciprocates along the second direction on the second-direction longitudinal beam. The third-direction vertical beam itself can also reciprocate along the third direction, thus the clamping bracket 312 connected to the end of the third-direction vertical beam can move in three-dimensional space. Since the truss three-dimensional structure in the three-dimensional driving component 311 is prior art, it will not be described in detail here.

[0337] Furthermore, the clamping bracket 312 is rotatably mounted at the end of the three-dimensional drive assembly 311, thus the direction of the material clamped by the clamping bracket 312 can be changed by controlling its rotation. Specifically, in this embodiment of the invention, the three-dimensional drive assembly 311 is mounted entirely above the third cutting device 3. The three-dimensional drive assembly 311 can drive the clamping bracket 312 to transfer between the second unloading conveyor 24, the third waiting platform 32, the main conveyor 57, the third cutting workbench 34, and the finished material unloading conveyor 36. Since the suitable material placement directions on each device are not the same, the present invention's rotatable mounting of the clamping bracket 312 at the end of the three-dimensional drive assembly 311 is more suitable for different material placement directions on different devices.

[0338] Furthermore, the multiple grippers at the end of the clamping bracket 312 are multiple suction cups, which are arranged sequentially along the axial direction of the clamping bracket 312. The multiple suction cups on the clamping bracket 312 can work together to pick up long strips of material on the waiting table, or they can work separately to pick up small pieces of finished material on the third cutting worktable 34. Therefore, the multiple suction cup assembly further improves the applicability of the transfer device 31 of this embodiment of the invention.

[0339] It should be noted that the transfer device 31 provided by this invention is mounted above the third cutting device 3, and its movement range includes above the third storage platform 32, the third cutting worktable 34, the finished material unloading and conveying device 36, and the subsequent total conveying device 57. It can complete the transfer of various materials, such as transferring the processed materials from the third storage platform 32 to the third cutting worktable 34. Because the second cutting device 2 takes a relatively long time to cut the arc-shaped middle material during the edge cutting process, the transfer device 31 can complete the transfer of other materials while satisfying the work of each cutting device, making the system structure simpler.

[0340] 4.2, Third Storage Platform 32

[0341] The third storage platform 32 provided in this embodiment of the invention consists of a platform support and a storage pad, and can simultaneously store at least two long strips of material produced by the second cutting device 2. Specifically, the third storage platform 32 is located on one side of the second feeding and conveying device 24. After the transfer device 31 picks up the long strip of material from the second feeding and conveying device 24, it moves a small distance to reach the third storage platform 32, saving the transfer time of the transfer device 31.

[0342] Specifically, when the second cutting device 2 feeds both the curved material and the long strip material onto the second feeding conveyor 24, the second feeding conveyor 24 drives the curved material and the long strip material to move along the conveying direction. At this time, the transfer device 31 transfers the curved material to the main conveyor 57 and the long strip material to the third storage platform 32. When the third cutting device 3 needs to feed material, the transfer device 31 then transfers the long strip material on the third storage platform 32 to the third cutting worktable 34.

[0343] Understandably, if the working cycle between the second cutting device 2 and the third cutting device 3 allows, the transfer device 31 can also directly pick up the long strip material from the second unloading transfer device 24 and transfer it to the third cutting worktable 34.

[0344] 4.3, Third Cutting Head 33

[0345] like Figure 20 As shown, the third cutting head 33 and the first cutting head 13 provided in this embodiment of the invention have similar structures, both being double-layer wire mesh structures, and the distance between adjacent cutting wire mesh layers is adjustable. The double-layer or multi-layer wire mesh structures of the third cutting head 33 and the first cutting head 13 are similar, and this invention will not elaborate further.

[0346] Furthermore, the head drive assembly of the third cutting head 33 provided in this embodiment of the invention includes a head support frame. The head support frame is provided with an axial drive assembly 331 and an axial guide rail. The third head frame 333 is slidably connected to the axial guide rail. The axial drive assembly 331 drives the third head frame 333 to reciprocate along the axial direction, specifically reciprocate along the axial direction of the third cutting worktable 34, so as to facilitate the selection of the cutting position of the third cutting head 33 for cutting long strips.

[0347] Furthermore, the head drive assembly of the third cutting head 33 also includes a cutting feed drive assembly 332 and a cutting feed device. The cutting feed device includes a head base plate, and the third head frame is slidably connected to an axial guide rail via the head base plate. A cutting feed rail is provided on the head base plate, and the third cutting head 33 is slidably connected to the cutting feed rail. The cutting feed drive assembly 332 drives the third cutting head 33 to reciprocate along the cutting feed rail to cut the long strip of material on the third cutting worktable 34. In a specific embodiment of the present invention, the cutting feed direction of the third cutting head 33 is perpendicular to the direction of the third cutting worktable 34.

[0348] The third cutting head 33 provided in this embodiment of the invention adopts a double wire mesh structure, which improves the cutting efficiency of the third cutting device 3, and the distance between the double wire meshes is adjustable, thereby adjusting the cutting length.

[0349] 4.4, Third Cutting Workbench 34

[0350] like Figures 21-22 As shown, the third cutting workbench 34 provided in this embodiment of the invention includes a support and clamping assembly. The support and clamping assembly specifically includes a rotating bracket 342. A support pad 343 is provided on the rotating bracket 342. A clamping and positioning device 344 and a backing plate 345 are respectively provided on opposite sides of the support pad 343. When a long strip is placed on the support pad 343, the clamping and positioning device 344 and the backing plate 345 move relative to each other to clamp and position the long strip, moving the long strip to a fixed position on the support pad 343.

[0351] In a specific embodiment of the present invention, the backing plate 345 is fixed on one side of the support pad 343, and the clamping and positioning device 344 is movably disposed on the other side of the support pad 343. By driving the clamping and positioning device 344 to move closer to the backing plate 345, the long strip is moved to a position where it abuts against the backing plate 345. Then, the clamping and positioning device 344 is driven to move away from the backing plate 345, waiting for the subsequent third cutting head 33 to cut the long strip on the support pad 343.

[0352] Furthermore, the clamping and positioning device 344 provided in this embodiment of the invention includes a plurality of clamping heads, which are arranged along the axial direction of the support pad 343 and can avoid the cutting path of the cutting tool. Correspondingly, the backing plate 345 is provided with a plurality of grooves in the axial direction for the cutting tool to pass through the grooves. Specifically, the cutting line of the third cutting head 33 passes through the grooves, thereby avoiding damage to the backing plate 345.

[0353] Furthermore, an auxiliary support device 346 is also provided on the support pad 343. The auxiliary support device 346 reciprocates along the support direction of the support pad 343 to protrude or retract the support surface of the support pad 343. After the clamping and positioning device 344 and the abutment plate 345 position the long strip, the auxiliary support device 346 extends until it comes into contact with the long strip and then stops moving. During the cutting operation of the long strip, the auxiliary support device 346 supports one small piece of finished material after cutting, providing stable support for each small piece of finished material and avoiding the phenomenon of silicon block breakage caused by uneven contact between the long strip and the support pad 343 during the cutting process.

[0354] Furthermore, the support plate 343 is provided with multiple slots, the distance between which corresponds to different cutting sizes, so that the cutting tool can pass through the slots. Specifically, the cutting line of the third cutting head 33 can pass through the slots without damaging the support plate 343. Understandably, each auxiliary support device 346 should have a slot on both sides so that a small piece of finished material can be fed in from both sides.

[0355] Furthermore, the third cutting workbench 34 provided in this embodiment of the invention also includes a support frame 341, and a support clamping assembly is rotatably disposed on the support frame 341. When the support clamping assembly rotates to a preset position, the material on the support pad 343 slides off, specifically the edge material placed on the support pad 343 slides off.

[0356] Specifically, a third unloading conveyor 35 is also provided on the side of the third cutting worktable 34. The support clamping assembly rotates outward to tilt the edge material on the third clamping assembly onto the third unloading conveyor 35. Since small pieces of finished material are produced during the cutting operation of long strips, small pieces of waste material are also generated on both sides of the long strips. The waste material is small and difficult to clamp. Therefore, the small pieces of waste material are tilted onto the third unloading conveyor 35, which not only improves the working efficiency of the third cutting device 3, but also helps to clean up the various waste materials on the third cutting device 3.

[0357] Furthermore, in order to prevent the support and clamping assembly from rotating during the cutting operation, the present invention also provides a locking device 348 at one axial end of the support and clamping assembly, the locking device 348 fixing the support and clamping assembly at the material receiving position.

[0358] Furthermore, the locking device 348 includes a locking platform and a locking drive assembly. A lock and a platform corresponding to the shape of the locking platform are provided on the rotation shaft of the supporting clamping assembly. When the locking drive assembly drives the locking platform and the lock and platform to abut, the rotation shaft of the supporting clamping assembly is locked. Specifically, the lock and platform can be notches provided on the rotation shaft, and the locking platform includes a locking flat block whose shape corresponds to the notch on the rotation shaft.

[0359] Furthermore, to improve cutting efficiency, the support and clamping assembly of the present invention includes two sets, which are arranged opposite to each other on the support frame 341. Accordingly, a third unloading conveying device 35 is provided on both sides of the support and clamping assembly, and the support and clamping assembly can rotate outward synchronously in opposite directions to dump waste material onto the third unloading conveying device 35.

[0360] Furthermore, the present invention employs a gear drive assembly 347 to drive two sets of support and clamping assemblies to rotate synchronously in opposite directions. The other ends of the two sets of support and clamping assemblies are meshed with each other through the gear drive assembly 347, which drives the oppositely arranged support and clamping assemblies to rotate synchronously in opposite directions. Specifically, the rotating brackets 342 of the two support and clamping assemblies are mounted in parallel on the support frame 341. Each rotating bracket 342 is connected to a gear at one end, and the two gears mesh with each other and are mounted at one end of the support frame 341. One gear is the driving gear, and the other is the driven gear. Under the drive of the servo motor, the two gears rotate in opposite directions, and therefore the rotating brackets 342 also rotate in opposite directions.

[0361] The third cutting worktable 34 provided in this embodiment of the invention has a support clamping assembly rotatably mounted on a support frame 341. When the support clamping assembly rotates to a preset position, the material on the support pad 343 slides off, improving the working efficiency of the equipment. In particular, for small-shaped waste materials, there is no need to use the transfer device 31 for transfer; they can directly fall to the waste collection device by sliding off, reducing the waste transfer process and thus improving the cutting efficiency. In addition, by using two sets of support clamping assemblies to clamp long strips, the cutting efficiency of the third cutting device 3 is further improved.

[0362] 4.5 Control method of the third cutting device 3

[0363] This invention also provides a control method for the third cutting device 3, which specifically includes:

[0364] S1. The transfer device 31 clamps the long strip material and transfers it to the third cutting worktable 34 of the third cutting device 3;

[0365] S2. The third cutting head 33 moves along the axial direction of the third cutting table 34 to adjust the cutting position of the third cutting head 33.

[0366] S3, the third cutting head 33 moves in a direction perpendicular to the third cutting table 34 to cut the long strip on the third cutting table 34.

[0367] After the third cutting head 33 completes the cutting, the control method of the third cutting device 3 also includes:

[0368] S34, the transfer device 31 transfers the small pieces of finished material on the third cutting workbench 34 to the finished material unloading and conveying device 36.

[0369] S35, the support and clamping assembly of the third cutting worktable 34 rotates outward to tilt the edge material on the support and clamping assembly to the third unloading and conveying device 35.

[0370] The third cutting device 3 provided in this embodiment of the invention, with its third cutting worktable 34 consisting of a double-wire mesh cutting head and a double support clamping assembly, increases the quantity of finished material after one cut, thereby improving the cutting efficiency.

[0371] 5. Material feeding and conveying system

[0372] like Figure 3 , Figure 4 as well as Figure 23 As shown, each cutting device of the cutting system A provided in this embodiment of the invention is equipped with a material feeding and conveying device, and each material feeding and conveying device constitutes the material feeding and conveying system provided in this embodiment of the invention.

[0373] It should be noted that, since the edge skin generates other materials in addition to intermediate materials during each cutting process, setting up a separate material collection device for each cutting device would not only increase the complexity of the equipment, but also be detrimental to the unified collection of materials. Therefore, the material feeding and conveying system provided in this embodiment of the invention combines the material feeding and conveying devices of each cutting device into a systematic material feeding and conveying system, making the entire equipment structure compact and simple, and facilitating the unified collection and management of waste materials.

[0374] Specifically, as can be seen from the foregoing embodiments, the first cutting device 1 further includes a first feeding conveyor 15, the second cutting device 2 further includes a second feeding conveyor 24, and the third cutting device 3 further includes a third feeding conveyor 35 and a finished product feeding conveyor 36. The cutting system A also includes a main conveyor 57 and a material collection device, wherein the material collection device is a waste collection box 58 located at the end of the main conveyor 57 on the side of the base. The main conveyor 57 collects all waste into the waste collection box 58, realizing unified collection and management of waste.

[0375] Furthermore, the first feeding conveyor 15 is disposed above the main conveyor 57, and the first feeding conveyor 15 is provided with a first guide plate 151, which guides the first material on the first feeding conveyor 15 to the main conveyor 57.

[0376] Furthermore, the first feeding conveyor 15 is used to convey end material, and the first guide plate 151 is a partition plate disposed on the conveying surface of the first feeding conveyor 15. The partition plate connects the two sides of the first feeding conveyor 15, so that the end material on the first feeding conveyor 15 is gradually guided by the partition plate to the main conveyor 57.

[0377] Furthermore, the second feeding conveyor 24 is arranged above the main conveyor 57. The second feeding conveyor 24 conveys the second intermediate material and the second material obtained by the second cutting device. The transfer device 31 transfers the second intermediate material to the third waiting platform 32 of the third cutting device 3 and transfers the second material 04 to the main conveyor 57.

[0378] Furthermore, the transmission end of the third feeding transmission device 35 is located above the main transmission device 57. The third feeding transmission device 35 may include two sets for conveying the third material generated by the third cutting device 3 to the main transmission device 57.

[0379] Furthermore, the main conveying device 57 conveys each material to the material collection device to complete the collection of all materials. As shown in the attached figure, the width of the main conveying device 57 is greater than that of other feeding conveying devices, which facilitates the collection of waste materials from different directions onto the main conveying device. Moreover, the first feeding conveying device 15 and the third feeding conveying device 35 can automatically convey materials to the main conveying device without additional operation.

[0380] It should be noted that the above-mentioned conveying devices are preferably belt conveyors, which mainly include a driving roller, a driven roller, and an annular belt sleeved on the driving roller and the driven roller. The driving roller is driven by a drive motor to rotate, thereby driving the annular belt to rotate as a whole. Generally, baffles are also provided on both sides of the belt, and the baffles are set higher than the plane of the belt to prevent materials from falling off the sides of the belt. The specific structure of the belt conveyor is prior art, and will not be described in detail in this invention.

[0381] The material feeding and conveying system provided by this invention has the following advantages:

[0382] a. The feeding and conveying devices of each cutting unit all convey waste to the main conveying device 57, so as to achieve unified collection of waste in each process, simplify the equipment structure and improve the waste collection efficiency.

[0383] b. The second cutting worktable of the second cutting device clamps the first intermediate material at the lifting device of the first cutting device, avoiding the transfer of the first intermediate material and improving the material transfer efficiency of the cutting system A.

[0384] c. After the second cutting workbench completes the cutting of the first intermediate material, it feeds the second intermediate material and the second waste material onto the second feeding conveyor 24, which further improves the material conveying efficiency of the cutting system A.

[0385] d. The transfer device 31 can complete the transfer of the second waste material between the main transfer device 57, the transfer of the second intermediate material between the third cutting device 3, and the transfer of the finished material between the third cutting device 3 and the finished material unloading transfer device 36. While making reasonable use of the cutting operation time cycle, it reduces the complexity of the equipment and makes the system structure simpler.

[0386] 6. Control method of cutting system A

[0387] The present invention also provides a control method based on the above-described cutting system A, which specifically includes:

[0388] S1. The first cutting device 1 performs a cutting operation on the two ends of the edge skin to obtain the middle arc top 01;

[0389] S2. The second cutting device 2 cuts off the arc-shaped surface of the material at the top of the arc to obtain a long strip.

[0390] S3, the third cutting device 3 cuts the long strip of material to obtain multiple finished materials.

[0391] Furthermore, the cutting operation of the first cutting device 1 on the two ends of the edge skin specifically includes the following steps:

[0392] S11. After the first cutting worktable 12 picks up the edge skin at the loading station of the first cutting device 1, it moves to the cutting station of the first cutting device 1.

[0393] S12, The first cutting head 13 performs a cutting operation on both ends of the edge skin to obtain the arc-top intermediate material and the end material;

[0394] S13. The first cutting workbench 12 clamps the arc-top intermediate material and the end material and transfers them to the first transmission device 14.

[0395] S14, the lifting device 145 of the first conveying device 14 lifts the arc top intermediate material and conveys the end material to the first unloading conveying device.

[0396] The specific control methods for the first cutting device 1 have been described in the foregoing embodiments and will not be repeated here.

[0397] Furthermore, the second cutting device 2 removes the arc-shaped surface of the intermediate material at the arc apex, specifically including the following steps:

[0398] S21, the feed drive assembly 21 of the second cutting worktable drives the second clamping device 22 to move to the loading station of the second cutting device 2, and the clamping base 222 of the second clamping device 22 drives the second clamping assembly to rotate to the position facing the middle material at the top of the arc, and the middle material at the top of the arc is clamped by the second clamping assembly.

[0399] S22, the clamping base 433 drives the second clamping assembly to rotate to a direction perpendicular to the second cutting head, and the feed drive assembly 21 drives the second clamping device 22 to move toward the second cutting head along the cutting feed direction to obtain arc-shaped material and long strip material;

[0400] S23, the clamping base 433 drives the second clamping assembly to rotate to a position facing the second feeding conveyor 24, the material support device 224 of the second clamping assembly retracts to allow the arc-shaped material to fall to the second feeding conveyor 24, and the clamping device 223 of the second clamping assembly opens to allow the long strip material to fall to the second feeding conveyor 24.

[0401] The specific control method for the second cutting device 2 has been described in the foregoing embodiments and will not be repeated here. Furthermore, the specific control method for the third cutting device 3 in step S3 has also been described in the foregoing embodiments and will not be repeated here.

[0402] The cutting system A provided by this invention also has the following advantages:

[0403] a. The first cutting device 1, the second cutting device 2 and the third cutting device 3 work together to cut the edge skin into small pieces of finished material, so as to realize the reuse of the edge skin and avoid waste of resources.

[0404] b. The material transfer system of cutting system A is composed of the first cutting worktable 12, the first transmission device 14, the second cutting worktable and the transfer device 31, which makes the material transfer between each cutting device smooth and convenient, avoids the use of too many transfer devices, simplifies the equipment structure and improves the working efficiency of the equipment.

[0405] II. Grinding System B

[0406] The grinding system B provided by this invention is used for grinding rectangular silicon blocks, specifically grinding the finished material obtained by the cutting system A to achieve the target dimensions between the processed surfaces and a better surface roughness. The equipment specifically includes a loading and unloading conveyor, a turret clamping mechanism 4, and a sliding grinding wheel mechanism 6.

[0407] like Figures 24-25As shown, the turret clamping mechanism 4 is equipped with multiple sets of third clamping components 5. By controlling the rotation of the turret clamping mechanism 4, the multiple sets of third clamping components 5 can be switched between multiple different workstations to cooperate in completing the grinding and loading / unloading operations of the silicon block. The multiple workstations include at least one loading / unloading workstation and at least one grinding workstation. The loading / unloading conveyor is set at the loading / unloading workstation to complete the loading / unloading of the silicon block at the loading / unloading workstation. The slide table grinding wheel mechanism 6 is set on the grinding workstation. The slide table grinding wheel mechanism 6 reciprocates along the radial direction of the turret clamping mechanism 4 on the grinding workstation to perform grinding operations on the silicon block.

[0408] The grinding system B provided in this embodiment of the invention uses a turret clamping mechanism 4 to clamp and rotate the silicon block to complete the conversion of the silicon block at different workstations. This enables continuous material preparation and continuous processing of silicon blocks with high processing efficiency. Moreover, the vertical turret design results in a small footprint and higher silicon block processing output per unit area of ​​the equipment.

[0409] The loading and unloading conveying device, turret clamping mechanism 4, and sliding grinding wheel mechanism 6 of the grinding system B of the present invention will be described below. It should be noted that the grinding system B of the present invention can be applied not only to grinding silicon blocks, but also to processing other materials. Therefore, silicon block grinding is not used as a basis for limiting the scope of protection of the grinding system B provided by the present invention.

[0410] Furthermore, since each workstation is arranged around the turret clamping mechanism (circumferential direction), this invention defines a separate coordinate system for each workstation to describe each component. Figure 28 For example, in this invention, the vertical direction of each workstation is taken as the third direction of the current workstation, namely the z-axis direction; the radial direction of the central turret 41 of the current workstation is taken as the second direction of the current workstation, namely the y-axis direction; and the tangential direction of the central turret 41 of the current workstation is taken as the first direction of the current workstation, namely the x-axis direction.

[0411] 1. Loading and unloading conveyor system:

[0412] The loading and unloading conveying device provided in this embodiment of the invention includes a conveying and transfer mechanism 30, a second storage device 40, and a transfer and centering mechanism 50.

[0413] like Figure 26 As shown, the conveying and transfer mechanism 30 provided in this embodiment of the invention includes a second transmission component 301 and a third transmission component 302. The second transmission component 301 is rotatably disposed between the first preset work station and the third transmission component 302, and the end of the third transmission component 302 away from the second transmission component 301 is disposed at the second preset work station.

[0414] In a specific embodiment of the present invention, the first preset station is the unloading station of the cutting system A, which is connected to the grinding system B, and the second preset station is the loading station of the grinding system B. Since the material transmission directions between the first preset station and the second preset station may be different, the present invention uses a conveying transfer mechanism 30, which can transmit materials between two stations with the same transmission direction, as well as between two stations with different transmission directions.

[0415] That is, the material transfer direction between the first preset station and the second preset station can be at any angle. By controlling the rotation of the second transfer component 301, the material is transferred between the first preset station and the third transfer component 302. This allows the material to be transferred between the first preset station and the second preset station via the second transfer component 301 and the third transfer component 302. As a result, when the two types of equipment are laid out as a whole, it is not necessary to consider that the transfer direction of the unloading station of the upstream processing equipment and the loading station of the downstream processing equipment must be the same. This improves the layout flexibility between different equipment in the same processing system and increases the utilization rate of factory space.

[0416] In a specific embodiment of the present invention, when the transfer mechanism 30 is disposed at the loading end of the grinding system B, that is, when it is connected to the second storage device 40, the first preset station is the unloading end of the upstream edge cutting equipment, and the second preset station is the second storage device 40. The second storage device 40 can receive material from any direction of the edge cutting equipment. The edge cutting equipment and the grinding system B are not limited by the transmission direction of loading and unloading, making the layout of different equipment more flexible. Therefore, the transfer mechanism 30 can make the installation of the entire edge material processing system more flexible. The transfer mechanism 30 provided in this embodiment of the present invention can realize 0° and 90° docking, and can also realize docking at other angles.

[0417] Understandably, the conveying and transfer mechanism 30 provided in this embodiment of the invention can also be set at the unloading end of the grinding system B, or between two processing devices in other large processing systems, to complete the material transfer between processing devices with different material conveying directions.

[0418] Furthermore, both the second transmission component 301 and the third transmission component 302 are transmission belts, and the delivery of materials is accomplished by controlling the rotation of the transmission belts along the transmission direction. Figure 26 As shown, the third transmission component 302 includes a second transmission belt and a second belt drive component, the second belt drive component driving the second transmission belt to rotate.

[0419] Specifically, the second transmission component 301 in this embodiment of the invention includes a rotary drive platform 3011 and a first transmission belt assembly disposed on the rotary drive platform 3011. By controlling the rotation of the rotary drive platform 3011, the first transmission belt assembly is driven to rotate as a whole. The first transmission belt assembly includes a first transmission belt and a first belt drive assembly. By controlling the rotation of the first transmission belt, the material placed on the first transmission belt is driven to move.

[0420] Furthermore, in one embodiment of the present invention, a preset clearance distance is maintained between the second transmission component 301 and the third transmission component 302 in the transmission direction of the third transmission component 302 to avoid interference between the second transmission component 301 and the third transmission component 302. Specifically, this can prevent interference between the second transmission component 301 and the third transmission component 302 during rotation. Since the second transmission component 301 is rotatable, to avoid interference between the second transmission component 301 and the third transmission component 302 during rotation, a first preset distance can be set between the second transmission component 301 and the third transmission component 302. This distance should be less than the length of the material being transmitted to ensure that the material can be smoothly transferred between the second transmission component 301 and the third transmission component 302.

[0421] In another embodiment of the present invention, a first translation drive assembly (not shown in the figures) is provided below the rotary drive platform 3011. The first translation drive assembly controls the second transmission assembly 301 to reciprocate along the transmission direction of the third transmission assembly 302, so as to avoid interference between the second transmission assembly 301 and the third transmission assembly 302 by controlling the translation of the first translation drive assembly. Specifically, when the second transmission assembly 301 rotates, the first translation drive assembly is controlled to translate away from the third transmission assembly 302 to avoid interference between the second transmission assembly 301 and the third transmission assembly 302. As an alternative embodiment, when the third transmission assembly 302 needs to rotate, the third transmission assembly 302 is controlled to move away from the third transmission assembly 302 to avoid interference with the third transmission assembly 302. After the second transmission assembly 301 finishes rotating, the second transmission assembly 301 is controlled to move closer to the third transmission assembly 302 to prevent the transmitted material from falling during the delivery between the second transmission assembly 301 and the third transmission assembly 302.

[0422] Furthermore, a second translation drive assembly (not shown in the attached figure) is provided below the rotary drive platform 3011. The second translation drive assembly controls the second transmission assembly 301 to reciprocate in the vertical direction. This allows the second transmission assembly 301 to adapt to materials of different transmission heights, while also preventing interference between the second transmission assembly 301 and other equipment such as the third transmission assembly 302 when the second transmission assembly 301 rotates by raising the second transmission assembly 301.

[0423] Furthermore, a second support 3012 is provided below the second transmission component 301, and a third support 3021 is provided below the third transmission component 302. The height of the second support 3012 is lower than that of the third support 3021, so that the transmission height of the second transmission component 301 can switch between above, flush with, and below the third transmission component 302.

[0424] Furthermore, a liftable foot device 303 is provided below the second support 3012 and the third support 3021. The lifting and lowering of the transmission and transfer mechanism 30 is controlled by controlling the lifting and lowering of the foot device 303 to adapt to different heights of the grinding system B.

[0425] In a specific embodiment of the present invention, one end of the third transmission component 302 is disposed at the loading station and / or unloading station of the grinding system B, and the second transmission component 301 is disposed at the unloading end of the upstream processing equipment (edge ​​cutting integrated machine) and / or the loading end of the downstream processing equipment (silicon block bonding equipment) of the grinding system B. It can be understood that the second transmission component 301 can also be disposed at the loading end or the unloading end of the grinding system B. Since the second transmission component 301 is rotatable, the grinding system B can adapt to incoming or unloading materials from different directions, making the entire edge material processing system more adaptable to the spatial environment.

[0426] The conveying and transfer mechanism 30 provided in this embodiment of the invention is not only applicable to the grinding system B of the present invention, but also applicable to various material processing systems. By being set between various processing equipment in the system, the layout of various equipment in the processing system is more flexible, and the processing system has lower requirements for factory space.

[0427] like Figure 27 As shown in the figure, the second storage device 40 provided in this embodiment of the invention is disposed at the loading end of the grinding system B, including a transverse conveying device 402 and a storage bin 401. One end of the transverse conveying device 402 is connected to the conveying transfer mechanism 30 to receive the silicon block conveyed by the conveying transfer mechanism 30, and the other end extends into the interior of the grinding system B to cooperate with the transfer centering mechanism 50 to complete the loading and centering of the silicon block. The transverse conveying device 402 passes through the interior of the storage bin 401, and the storage bin 401 is provided with multiple sets of lifting and lowering storage positions 4011. By controlling the lifting and lowering of the storage positions 4011, the storage and discharge of materials in the storage bin 401 can be realized.

[0428] Furthermore, the lateral conveying device 402 conveys the material to the storage bin 401 along the first direction. The storage bin 401 is provided with a plurality of storage positions 4011. The plurality of storage positions 4011 reciprocate along the third direction to transfer the material on the lateral conveying device 402 to the storage position 4011 or transfer the material in the storage position 4011 to the lateral conveying device 402.

[0429] Furthermore, the lateral conveying device 402 includes a conveyor belt and a drive assembly for controlling the rotation of the conveyor belt. After receiving the silicon block, the lateral conveying device 402 drives the silicon block to the storage bin 401 by controlling the rotation of the conveyor belt.

[0430] Furthermore, the storage bin 401 includes multiple sets of opposing storage racks 4013. Two opposing storage racks 4013 are respectively arranged on both sides of the transverse conveyor 402 to form a storage position 4011. As shown in the attached figure, the transverse width of the material placed on the transverse conveyor 402 is greater than the width of the transverse conveyor 402 (the width of the conveyor belt), so that the two ends of the material protrude from the transverse conveyor 402 and are located above the storage racks 4013. When storage is required, the storage racks 4013 on both sides are controlled to rise simultaneously, and the storage racks 4013 carry the material away from the transverse conveyor 402 to complete the storage of the material; when unloading is required, the storage racks 4013 on both sides are controlled to fall simultaneously, so that the material is placed back on the transverse conveyor 402. At this time, the transverse conveyor 402 is controlled to move the material horizontally to the loading station to complete the loading of the material.

[0431] The second storage device 40 provided in this embodiment of the invention can serve as an incoming material buffer for the entire automated production line, used to store silicon blocks from the upstream production line, thereby increasing the automation level of the entire system. Furthermore, since the storage bin 401 is arranged perpendicular to the horizontal conveying device 402, it does not occupy the space of the horizontal conveying device during storage. This results in a smaller footprint for the entire second storage device 40 while simultaneously storing silicon blocks, making the equipment structure more compact.

[0432] Furthermore, the storage bin 401 provided in this embodiment of the invention also includes lifting components 4012 disposed on both sides of the transverse conveying device 402, and storage racks 4013 are evenly disposed on the lifting components 4012. By controlling the two opposing lifting components 4012 to reciprocate synchronously in a third direction, the opposing storage racks 4013 are driven to reciprocate synchronously in a third direction. Specifically, the lifting component 4012 can be a lifting chain assembly. The storage racks 4013 are fixedly disposed on the lifting components 4012. In order to maintain stability, two or more lifting components 4012 are disposed on one side of the transverse conveying device 402, and the storage racks 4013 are evenly fixed on the lifting components 4012 so that the storage racks 4013 remain stable during lifting movement.

[0433] Furthermore, the storage bin 401 provided in this embodiment of the invention also includes a lifting drive assembly 4014, which is used to drive the lifting assembly 4012 to move upward or downward. Specifically, the lifting drive assembly 4014 includes a first driven gear and a second driven gear that mesh with each other. A chain drive assembly is respectively fitted on the first driven gear and the second driven gear. The other end of the chain drive assembly is connected to the lifting assemblies 4012 on both sides of the transverse transmission device 402, so as to drive the lifting assemblies 4012 on both sides simultaneously to achieve lifting and lowering movements through a set of motors, ensuring the synchronous lifting and lowering of the storage rack 4013 and preventing the material from tipping over due to the asynchronous movement of the two storage racks 4013 during the rising or falling process.

[0434] The second material storage device 40 provided in this embodiment of the invention is not only applicable to the grinding system B of the present invention, but also applicable to the material buffer device of other processing equipment. For the edge material processing system, since multiple silicon blocks are generated at one time after the edge material is cut in the previous process, the grinding system B cannot process multiple silicon blocks generated at one time at the same time during the grinding process. Therefore, the second material storage device 40 enables the grinding system B to be more compatible with the upstream processing equipment, eliminating the need for manual material preparation and making the automation level of the entire system higher.

[0435] like Figures 28-30 As shown, the transfer and centering mechanism 50 provided in this embodiment of the invention is disposed at the loading and unloading station, including a second transfer component and a centering component. The second transfer component includes a spatial transfer device and a gripping execution device at the end of the spatial transfer device, so as to drive the gripping execution device to transfer materials at the loading station through the spatial transfer device. The centering component includes a second gripper component arranged opposite to each other. The second gripper component moves synchronously relative to each other along a first direction to perform a centering operation on the material. Specifically, the second gripper component performs a centering operation on the silicon block placed on the third clamping component 5 at the loading station.

[0436] In a specific embodiment of the present invention, the loading and unloading of the grinding system B are located at the same station, so the second transfer component can simultaneously complete the loading and unloading of the silicon block. After the second transfer component places the silicon block on the fourth chuck 521 of the third clamping component 5 of the turret clamping mechanism 4, the centering component performs a centering clamping operation on the silicon block, so that the center of the silicon block coincides with the center of the third clamping component 5, that is, the center of the material coincides with the material clamping center of the loading station, so as to facilitate subsequent grinding operations.

[0437] Furthermore, the transfer centering mechanism 50 also includes a second support component 501, one end of which is fixed to the loading station, and the other end is connected to the spatial transfer device of the second transfer component; the second support component 501 is also provided with a centering component sliding guide rail 506 extending in a third direction, and the second gripper assembly also includes a centering gripper base plate 5010, one side of which is slidably connected to the centering component sliding guide rail 506, and the other side of which is connected to the second gripper assembly.

[0438] Specifically, the second support assembly 501 is provided with a centering screw extending in a third direction, and the centering gripper base plate 5010 is provided with a centering bolt. The centering bolt is connected to the centering screw so that by controlling the rotation of the centering assembly screw, the second gripper assembly as a whole can be controlled to reciprocate in a third direction.

[0439] In this embodiment of the invention, the spatial transfer device and the centering component are designed coaxially, coordinating the clamping, transfer, and centering operations of the material at the loading station, saving space at the loading station and making the equipment structure compact. The centering component as a whole can reciprocate along a third direction, facilitating the centering and clamping operations of materials with different thicknesses and heights.

[0440] In a specific embodiment of the present invention, the second support component 501 is a support frame extending along a third direction. One end of the frame is fixed to the base of the grinding system B, and the other end is connected to the first direction crossbeam 502 of the spatial transfer device. The spatial transfer device provided in this embodiment includes the first direction crossbeam 502 and the first direction drive component. A third direction vertical beam 503 is slidably connected to the first direction crossbeam 502. A third direction drive component is provided on the third direction vertical beam 503. The first direction drive component drives the third direction vertical beam 503 to reciprocate on the first direction crossbeam 502. A suction cup component is connected to the end of the third direction vertical beam 503. The third direction drive component drives the suction cup component to reciprocate on the third direction vertical beam 503. The suction cup component serves as the gripping execution device of the second transfer component to pick up materials.

[0441] Specifically, the first direction crossbeam 502 is provided with a first direction lead screw and a lead screw drive motor for driving the first direction lead screw to rotate. The third direction vertical beam 503 is connected to the first direction lead screw by bolts, and the rotation direction of the first direction lead screw is controlled by the lead screw drive motor, thereby realizing the reciprocating motion of the third direction vertical beam 503 in the first direction.

[0442] Furthermore, a vertical beam cylinder is provided on the third-party vertical beam 503, and the suction cup assembly is located at the end of the vertical beam cylinder. By controlling the extension and retraction of the vertical beam cylinder, the reciprocating motion of the suction cup assembly in the third-party direction is realized.

[0443] The spatial transfer device provided in this embodiment of the invention has a simple structure for spatial motion control, enabling it to quickly transfer silicon blocks between the second storage device 40 and the loading station, thereby improving the overall operating efficiency of the equipment.

[0444] In a specific embodiment of the present invention, since the suction cup assembly needs to place the silicon block on the fourth chuck 521 of the third clamping component 5 of the turret clamping mechanism 4, in order to avoid interference with the third clamping component 5 of the turret clamping mechanism 4, the suction cup assembly provided in this embodiment of the present invention includes a second direction extension plate 504. One end of the second direction extension plate 504 is connected to the end of the third direction vertical beam 503, and the other end is connected to at least one suction cup 505. The second direction extension plate 504 maintains a preset extension distance between the suction cup 505 and the end of the third direction vertical beam 503, thereby avoiding interference between the second transfer component and the third clamping component 5 on the turret clamping mechanism 4.

[0445] Furthermore, the second gripper assembly provided in this embodiment of the invention includes a first centering gripper 507 and a second synchronous drive assembly arranged opposite to each other along a first direction. The second synchronous drive assembly can drive the two first centering grippers 507 to move synchronously relative to each other along the first direction, thereby realizing the centering operation of the silicon block at the loading station, so that the center of the silicon block coincides with the clamping center of the loading station.

[0446] Specifically, the second synchronous drive assembly can be a gear and rack structure, a ball screw structure, or other device capable of achieving synchronous reverse movement of the two first centering jaws 507. In a specific embodiment of the present invention, the second synchronous drive assembly includes a centering drive motor, a bidirectional lead screw, and a centering guide rail. The bidirectional lead screw and the centering guide rail are arranged parallel to each other along a first direction. The two first centering jaws 507 are respectively mounted on the positive thread section and the negative thread section of the bidirectional lead screw, and are slidably arranged on the centering guide rail. The centering drive motor is connected to the bidirectional lead screw for transmission. By driving the bidirectional lead screw to rotate through the centering drive motor, the oppositely arranged first centering jaws 507 are driven to move synchronously in opposite directions. The synchronous reverse movement of the first centering jaws 507 in the present invention ensures that the stroke of the oppositely arranged first centering jaws 507 is the same each time, thereby guaranteeing the accuracy of the centering operation.

[0447] Furthermore, the second gripper assembly is also provided with a centering probe assembly 508, as shown in the attached figure. Figure 31As shown, the centering probe assembly 508 is positioned in front of the first centering jaw 507 and operates synchronously with it. As the first centering jaw 507 approaches the material, the centering probe assembly 508 detects the position of the material's side surface, allowing the first centering jaw 507 to control its movement speed based on its distance from the material. This provides a mechanism where, when the centering probe assembly 508 is not in contact with the material, the first centering jaw 507 moves rapidly; and when it contacts the material, the centering probe retracts, and the first centering jaw 507 performs the centering operation slowly. This improves centering and clamping efficiency while preventing the first centering jaw 507 from bumping into the material due to excessive speed. Furthermore, by simultaneously detecting the material's position using the centering probe assemblies 508 on both sides, the distance between the material and its side surface can be obtained, thereby determining the grinding allowance of the material.

[0448] Furthermore, the alignment probe assembly 508 includes an alignment probe and a probe driving assembly. The probe driving assembly drives the alignment probe to reciprocate along a first direction to control the alignment probe to protrude or retract from the clamping surface of the first alignment jaw 507. This allows for position detection and measurement of the material when the alignment probe protrudes from the clamping surface of the first alignment jaw 507, and for controlling the first alignment jaw 507 to complete the alignment and clamping operation of the silicon block when the probe retracts from the clamping surface, thus preventing the probe from interfering with the alignment and clamping operation of the first alignment jaw 507.

[0449] Understandably, in addition to driving the centering probe to protrude or retract from the clamping surface of the first centering jaw 507 via the probe driving component, the centering probe can also be connected to the first centering jaw 507 via an elastic element. When the first centering jaw 507 performs the centering clamping operation, the centering probe retracts under the action of material pressure. When the first centering jaw 507 releases the material, the centering probe extends out from the clamping surface of the first centering jaw 507 under the action of elastic force, so as to facilitate the measurement and detection of the material.

[0450] Furthermore, the first centering jaw 507 provided in this embodiment of the invention includes a clamping block disposed on the opposite side of the first centering jaw 507, and the clamping surface of the clamping block maintains a preset length and width to adapt to clamping materials of different sizes.

[0451] Furthermore, the centering assembly provided in this embodiment of the invention also includes a second direction driving assembly 509. The centering gripper base plate 5010 is connected to the second direction driving assembly 509, and the second direction driving assembly 509 controls the centering gripper base plate 5010 to drive the second gripper assembly to reciprocate along the second direction. By controlling the centering assembly to reciprocate along the second direction, the first centering gripper 507 is driven to move towards the material.

[0452] Specifically, the second direction drive assembly 509 is a rack extending along the second direction on the second gripper assembly and a rack drive assembly fixed on the base. The gear at the drive end of the rack drive assembly meshes with the rack on the second gripper assembly, and the rack reciprocates along the second direction by rotating the drive gear.

[0453] Furthermore, the centering component also includes a centering calibration device. The centering calibration device and the loading station are in a relatively fixed position. The centering probe component 508 determines the material clamping center of the loading station by detecting the centering calibration device.

[0454] The control process of the loading and unloading conveyor is briefly introduced below:

[0455] S1. The conveying and transfer mechanism 30 transfers the material to the second storage device 40;

[0456] S2, the storage bin 401 of the second storage device 40 stores the material to the storage position 4011;

[0457] S3. When the grinding system B needs to be fed, the storage bin 401 will transfer the material to the transverse conveying device 402 of the second storage device 40, and the transverse conveying device 402 will transfer the material to the material gripping position of the second transfer component.

[0458] S4. After the gripping execution device of the second transfer component grips the material, the space transfer device transfers the material to the loading and unloading station.

[0459] S5. The centering component detects the position and size of the materials at the loading and unloading stations and completes the centering displacement operation of the materials.

[0460] S6. When the grinding system B needs to unload material, the gripping execution device of the second transfer component grips the material at the loading and unloading station and then the space transfer device transfers the material to the unloading end.

[0461] The above steps constitute the complete operation flow of the loading and unloading conveyor device. Specifically, step S5, where the centering component completes the material centering operation, further includes:

[0462] S51, the turret clamping mechanism 4 drives a third clamping component 5 to rotate to the loading and unloading station, and the second transfer component clamps the material and places it on the fourth chuck 521 of the third clamping component 5.

[0463] S52, The centering component performs a centering operation on the first processed side of the material and detects the first processed side by a centering detection probe to determine the processing allowance of the first processed side;

[0464] S53 and the fourth chuck 521 drive the material to rotate as a whole so that the second processing side is positioned opposite to the centering component. The centering component performs a centering operation on the second processing side of the material, and the centering detection probe detects the second processing side to determine the processing allowance of the second processing side.

[0465] The loading and unloading conveying device provided in this embodiment of the invention can not only receive materials from different conveying directions, but also store materials through the second storage device 40. At the same time, it can complete the loading and unloading of materials, as well as the centering operation and size detection of materials. The entire system has a compact structure and a higher degree of automation, which simplifies the workflow for subsequent processing operations and also simplifies the structural complexity of the equipment.

[0466] 2. Turret clamping mechanism 4:

[0467] The turret clamping mechanism 4 provided in this embodiment of the invention is rotatably mounted on a base, including a central turret 41 and a plurality of third clamping components 5 arranged along the circumferential direction of the central turret 41. The central turret 41 can rotate along its central axis. In a specific embodiment of the invention, the central axis of the central turret 41 is a rotation axis perpendicular to the base direction. The central turret 41 rotates along the central axis to drive each third clamping component 5 to rotate between different workstations. Correspondingly, the base is provided with workstations corresponding to the third clamping components 5 on the turret clamping mechanism. Therefore, after one silicon block clamping and alignment, multiple processing workstations can simultaneously perform grinding operations such as rough grinding and fine grinding of the silicon block, so as to achieve the purpose of processing multiple silicon blocks simultaneously in one processing cycle, thereby improving the grinding efficiency of the silicon block.

[0468] like Figures 32-34 As shown, in a specific embodiment of the present invention, the turret clamping mechanism 4 includes a central turret 41 and three third clamping components 5 evenly arranged along the circumferential direction of the central turret 41, that is, the included angle between two adjacent third clamping components 5 is 120°. Corresponding to the turret clamping mechanism 4, the base of the grinding system B is provided with a loading and unloading station, a rough grinding station and a fine grinding station, and the included angle between each station is also 120°. Therefore, after the silicon block completes the centering and clamping operation at the loading and unloading station, the rough grinding and fine grinding processes can be completed sequentially by controlling the rotation of the turret clamping mechanism 4. Finally, it is rotated to the loading and unloading station and the silicon block is unloaded by the transfer centering mechanism 50.

[0469] Furthermore, a second rotary drive assembly 42 is provided on the base, which drives the central turret 41 to rotate as a whole. A rotary gear is provided at one axial end of the central turret 41, and the turret clamping mechanism 4 also includes a gear drive assembly that meshes with the rotary gear. The gear drive assembly drives the rotary gear to rotate, thereby driving the central turret 41 to rotate as a whole. In a specific embodiment of the present invention, the rotary gear is located at the bottom end of the central turret 41, and the gear drive assembly includes a drive gear meshing with the rotary gear on the base and a gear drive motor located within the base to drive the drive gear to rotate. The present invention uses a gear drive to control the rotation angle of the central turret 41, which can ensure the rotational accuracy of the central turret 41, thereby ensuring the processing accuracy of silicon ingot grinding.

[0470] Furthermore, a slip ring bracket 43 and a slip ring assembly are provided at one axial end of the central turret 41. The slip ring bracket 43 fixes the slip ring assembly to a preset position on the central turret 41. The fixed end of the slip ring assembly is connected to a preset external power source. The external power source is connected to the rotating end of the slip ring assembly through the interior of the slip ring assembly. The rotating end of the slip ring assembly is connected to the power equipment inside the turret clamping mechanism 4 to transmit the external power source to the power equipment inside the turret clamping mechanism 4. The external power source can be a power source, a gas source, or an oil source. The power equipment can be not only a rotational power equipment, but also other equipment that is suitable for gas or oil.

[0471] In a specific embodiment of the present invention, the turret clamping mechanism 4 includes a slip ring bracket 43 at the top and a slip ring assembly. The slip ring assembly is fixed above the central turret 41 of the turret clamping mechanism 4 via the slip ring bracket 43. The slip ring assembly delivers electricity, gas, and lubricating oil into the interior of the central turret 41. The present invention uses an electric slip ring device to provide power to the electrical, gas, and lubrication equipment of the central turret 41, while also avoiding the wiring entanglement problem caused by continuously providing power to the electrical equipment of the rotating material loading unit.

[0472] The turret clamping mechanism 4 rotates along the central axis via the central turret 41 to drive each third clamping component 5 to rotate between different workstations, enabling simultaneous processing of multiple materials within one work cycle and improving the processing efficiency of the equipment.

[0473] like Figures 34-36 As shown, the third clamping assembly 5 on the turret clamping mechanism 4 includes a first clamping assembly 51 and a second clamping assembly 52 arranged opposite to each other along the axial direction of the central turret 41. The first clamping assembly 51 and the second clamping assembly 52 reciprocate along the axial direction of the central turret 41 to clamp or release materials.

[0474] It should be noted that the third clamping component 5 provided in this embodiment of the invention can be applied not only to the turret clamping mechanism 4 of the grinding system B, but also to other second rotating frames or moving frames.

[0475] Furthermore, the first chuck assembly 51 includes a clamping chamber and a third chuck 511. The clamping chamber is provided with a clamping drive assembly 513. The clamping chamber forms an internally sealed space, thus the clamping chamber isolates the clamping drive assembly 513 from the external environment and prevents dust and water mist generated during the equipment processing from entering the interior of the clamping drive assembly 513.

[0476] Furthermore, the clamping chamber includes a cover 541 and a clamping drive assembly 513 within the cover 541. The cover 541 is connected to the side wall of the central turret 41. A third chuck 511 extends through a first opening on the cover 541 to the outside of the cover 541. The clamping drive assembly 513 drives the third chuck 511 to reciprocate along the axial direction of the central turret 41. This invention uses a clamping chamber to protect the clamping drive assembly 513 within the cover 541, preventing silicon powder and water mist from affecting the clamping drive assembly 513 during processing and ensuring the operational stability of the equipment.

[0477] Furthermore, the first chuck assembly 51 also includes a first chuck bracket 512 and a third chuck 511. A clamping slide rail is provided inside the cover 541 of the clamping chamber. Specifically, the clamping slide rail is provided on the side wall of the central turret 41. One end of the first chuck bracket 512 is slidably connected to the clamping slide rail, and the other end extends radially away from the central turret 41 and connects to the third chuck 511. The clamping drive assembly 513 drives the first chuck bracket 512 to reciprocate on the clamping slide rail, so as to drive the third chuck 511 located at the end of the first chuck bracket 512 to reciprocate along the clamping direction.

[0478] Furthermore, the clamping drive assembly 513 also includes a clamping screw and a clamping screw drive motor. The first chuck bracket 512 is connected to the clamping screw, and the clamping screw is driven to rotate by the clamping screw drive motor, which in turn drives the first chuck bracket 512 to reciprocate along the axial direction of the clamping screw.

[0479] In a specific embodiment of the present invention, the third chuck 511 is disposed at the upper end of the central turret 41, and the fourth chuck 521 is disposed at the lower end of the central turret 41. The silicon block is placed on the fourth chuck 521. The clamping and releasing of the silicon block is achieved by controlling the reciprocating motion of the third chuck 511. This ensures the stable placement of the silicon block on the fourth chuck 521 and avoids the position of the silicon block on the fourth chuck 521 being affected by the movement of the fourth chuck 521 during the clamping process, thereby improving the stability of the clamping operation.

[0480] Furthermore, since the third chuck 511 needs to reciprocate at the first opening of the clamping chamber, to prevent silicon powder and water mist from entering the cover 541 through the first opening, the clamping chamber provided in this embodiment of the invention also includes a chuck accordion cover 542. The chuck accordion cover 542 is a closed annular cover, with one axial end connected to the first chuck support 512 and the other end connected to the first opening. The chuck accordion cover 542 ensures the reciprocating motion of the third chuck 511 while preventing dust and water mist from entering the cover 541 through the first opening, further improving the protection level of the clamping chamber.

[0481] Furthermore, the cover 541 is provided with a second opening 543, which is connected to an external air source to blow air into the clamping chamber, so that the inner cavity of the clamping chamber is in a slightly positive pressure state. The slightly positive pressure state increases the resistance of external dust and water mist to entering the clamping chamber, further improving the protection level of the clamping chamber.

[0482] Furthermore, the fourth chuck 521 includes a second chuck bracket 522 and a fourth chuck 521. One end of the second chuck bracket 522 is connected to the side wall of the second rotating frame, and the other end extends radially away from the second rotating frame and is connected to the fourth chuck 521 at the end of the second chuck bracket 522.

[0483] Furthermore, the fourth chuck 521 can rotate around its central axis to drive the material placed on the fourth chuck 521 to rotate as a whole, so that the material can be rotated by the fourth chuck 521 to cooperate with the processing device to process different sides of the material.

[0484] Specifically, the second chuck assembly 52 also includes a chuck rotation drive assembly, which includes a chuck rotation motor 524 and a chuck bearing 523. The fourth chuck 521 is connected to the rotation shaft of the chuck rotation motor 524 through the chuck bearing 523. The fourth chuck 521 is driven to rotate by the chuck rotation motor 524, so as to drive the material on the fourth chuck 521 to rotate.

[0485] Furthermore, the first chuck assembly 51 also includes a driven bearing 515 and a floating chuck 514. The floating chuck 514 is connected to the third chuck 511 via the driven bearing 515, so that the floating chuck 514 rotates with the fourth chuck 521. By providing a floating chuck 514 on the third chuck 511, the present invention allows the third clamping assembly 5 to clamp the material while simultaneously rotating the entire material along the central axis of the third clamping assembly 5, preventing the material from shifting on the clamping assembly during rotation and ensuring that the center of the material remains aligned with the center of the third clamping assembly 5.

[0486] Since grinding silicon blocks requires grinding in both the 0° and 90° directions, in order to ensure that the silicon block can be rotated while being clamped, this invention adopts a method in which the fourth chuck 521 actively rotates and the third chuck 511 passively rotates. This method ensures that the silicon block will not shift its position while rotating, thereby ensuring that the clamping center always coincides with the center of the silicon block and thus ensuring grinding accuracy.

[0487] During the grinding operation, the grinding wheel 624 rotates at high speed between the third chuck 511 and the fourth chuck 521. Therefore, the third clamping assembly 5 needs to provide grinding clearance space for the grinding wheel 624. Specifically, the present invention connects the central turret 41 through the first chuck bracket 512 and the second chuck bracket 522, so that the clamping centers of the third chuck 511 and the fourth chuck 521 maintain a certain distance from the side wall of the central turret 41, providing machining clearance space for the grinding wheel to perform the grinding operation.

[0488] Furthermore, the third chuck 511 has a preset first axial length in the axial direction, and the fourth chuck 521 has a second axial length in the axial direction, so as to provide processing clearance space when the third clamping assembly 5 clamps the material.

[0489] In a specific embodiment of the present invention, since the silicon block is small in size and the grinding wheel used to grind the silicon block is larger in size than the silicon block, the present invention provides clearance space for the grinding wheel during grinding operation by extending the axial length of the third chuck 511 and the fourth chuck 521.

[0490] The turret clamping mechanism 4 provided in this embodiment of the invention is applicable not only to the grinding system B of the present invention, but also to other processing equipment. The turret clamping mechanism 4 can cooperate to complete the simultaneous processing operations at different workstations, making the entire equipment structure compact, improving processing efficiency, and ensuring the stable operation of the equipment.

[0491] 3. Slide table grinding wheel mechanism 6

[0492] In this embodiment of the invention, both the rough grinding station and the fine grinding station of the grinding system B are equipped with a sliding grinding wheel mechanism 6. By controlling the grinding wheel assembly 62 of the sliding grinding wheel mechanism 6 to reciprocate along the radial direction of the central turret 41, the grinding operation of the silicon block is realized.

[0493] like Figures 37-39 As shown, the slide table grinding wheel mechanism 6 provided in this embodiment of the invention includes a slide table feed guide rail 63 arranged along the second direction of the grinding station, a grinding wheel slide 61 slidably connected to the slide table feed guide rail 63, and a slide table feed drive assembly. Two grinding wheel assemblies 62 are arranged opposite to each other on the grinding wheel slide 61. The slide table feed drive assembly drives the grinding wheel slide 61 to reciprocate along the second direction to move closer to or away from the third clamping assembly 5.

[0494] Furthermore, a grinding wheel feed guide and a grinding wheel feed drive assembly are arranged opposite each other on the grinding wheel slide 61 along the first direction of the grinding station. The grinding wheel assemblies 62 are slidably arranged on the grinding wheel feed guide. The grinding wheel feed drive assembly drives the grinding wheel assemblies 62 to reciprocate along the first direction so that the two opposite grinding wheel assemblies 62 move closer or further away from each other.

[0495] The slide grinding wheel mechanism 6 provided in this embodiment of the invention controls the grinding wheel assembly 62 to move closer to the third clamping assembly 5 via the grinding wheel slide 61, ensuring that the left and right grinding wheels are fed synchronously during high-speed grinding, making the grinding process more stable.

[0496] Furthermore, during the grinding operation of the grinding wheel assembly 62, the grinding wheel 624 rotates at high speed and feeds along the grinding direction. This can cause the grinding wheel to overheat. If the grinding wheel 624 is under such conditions for a long time, defects will appear on its surface, ultimately affecting the quality of the ground silicon block surface. Therefore, in this embodiment of the invention, a corresponding cooling system is designed for the grinding wheel.

[0497] Specifically, the grinding wheel assembly 62 includes a grinding wheel drive assembly 623, a grinding wheel 624, and a spindle unit. The spindle unit includes a rotating spindle (not shown in the figure) and a spindle housing 621 coaxially arranged with the rotating spindle. The rotating spindle is enclosed inside the spindle housing 621, and the rotating spindle and the spindle housing 621 are relatively independent. While the rotating spindle maintains high-speed rotation, the spindle housing remains relatively stationary. Therefore, the grinding wheel drive assembly 623 drives the rotating spindle to rotate, thereby driving the grinding wheel 624 connected to the end of the rotating spindle to rotate. A grinding wheel cooling assembly 625 is provided at one end of the spindle housing 621 to cool the grinding wheel.

[0498] Furthermore, the grinding wheel cooling assembly 625 includes a liquid inlet and a nozzle extending to the side of the grinding wheel 624. The liquid inlet is connected to external coolant, and the coolant is sprayed onto the grinding wheel 624 through the nozzle. The grinding wheel cooling assembly 625 provided in this embodiment of the invention can effectively reduce the temperature of the grinding wheel 624 by spraying coolant onto the grinding wheel separately, thereby improving grinding efficiency and grinding quality.

[0499] Furthermore, since silicon powder and water mist are generated during the grinding process, the slide grinding wheel mechanism 6 also includes a grinding wheel drive chamber. A grinding wheel drive assembly 623 is disposed inside the grinding wheel drive chamber. One end of the spindle unit extends into the grinding wheel drive chamber to connect the rotating spindle to the grinding wheel drive assembly 623, and the other end extends out of the grinding wheel drive chamber and is connected to the grinding wheel at the end. The grinding wheel drive chamber includes a grinding wheel cover 641, which protects each drive assembly in a sealed internal space, preventing water mist and silicon powder from affecting the drive assemblies.

[0500] Furthermore, a bellows-shaped protective cover 642 is installed on the main shaft unit outside the grinding wheel drive chamber. One end of the bellows-shaped protective cover 642 is fixedly connected to the grinding wheel drive chamber, and the other end is connected to the end of the main shaft housing 621. The bellows-shaped protective cover 642 prevents water mist and silica powder from entering the grinding wheel drive chamber through the gaps in the main shaft unit, further ensuring the stable operation of the equipment.

[0501] Furthermore, the grinding wheel drive chamber is provided with an air inlet 643 to blow air into the grinding wheel drive chamber. The air inlet 643 is connected to an external air source, which makes the grinding wheel drive chamber present a slightly positive pressure state, providing resistance to the entry of external dust and water mist, and playing a secondary auxiliary sealing role.

[0502] Furthermore, the grinding wheel drive assembly 623 includes a grinding wheel rotation drive motor and a tension belt. The rotating shaft of the grinding wheel rotation drive motor is connected to the rotating main shaft through the tension belt. The grinding wheel rotation drive motor drives the tension belt to rotate, thereby driving the rotating main shaft to rotate.

[0503] Furthermore, the grinding wheel drive assembly 623 also includes a belt adjustment device, which includes a belt shaft mounting plate and multiple elongated holes on the belt shaft mounting plate. The rotating shaft at one end of the tension belt is mounted in the elongated hole by a bolt assembly, and the other end of the tension belt is connected to the rotating spindle. The tension of the tension belt is adjusted by adjusting the position of the bolt assembly in the elongated hole.

[0504] This invention utilizes a motor to drive a synchronous belt, which in turn drives a main shaft unit, which in turn drives a grinding wheel 624, ultimately achieving high-speed rotation of the grinding wheel 624. The device incorporates a belt tensioning mechanism to adjust the belt tension and ensure stable operation. The overall structure is compact and highly space-efficient.

[0505] In addition, the grinding wheel drive assembly also includes a calibration probe assembly 65, which is used to detect the position of the material to be ground. The calibration probe assembly 65 includes a calibration probe and a calibration probe drive assembly, which drives the calibration probe to reciprocate along a first direction to protrude or retract onto the grinding surface of the grinding wheel 624. The calibration probe assembly 65, together with the turret clamping mechanism 4, constitutes the machining position correction system of the machining equipment provided in this embodiment of the invention. The machining position correction system will be further described below.

[0506] 4. Machining position correction system

[0507] like Figure 40As shown, in this embodiment of the invention, a calibration device 54 is also provided on the third clamping component 5. In order to avoid the rotation error of the central turret 41 during the rotation process from affecting the grinding accuracy of the silicon block, this embodiment of the invention introduces a calibration probe on the grinding wheel component 62 and a position calibration component on the third clamping component 5, which can calibrate the rotation angle of the central turret 41 and further improve the grinding accuracy of the silicon block.

[0508] The present invention comprises a machining position correction system provided in the embodiment of the present invention, consisting of a turret clamping mechanism 4, a third clamping component 5 and a calibration device 54 on the turret clamping mechanism 4, a calibration probe component 65 on the slide grinding wheel mechanism 6, and a positioning device 44 on the grinding station.

[0509] It should be noted that this position correction system can be applied not only to grinding system B, but also to other processing equipment with similar structures to the present invention, such as a slide mechanism with a structure similar to the slide grinding wheel mechanism 6, and the slide mechanism is provided with corresponding processing components. By setting corresponding calibration probe components 65 on the processing components, the processing position correction of the above embodiment can be achieved.

[0510] Specifically, the system includes a base, a turret clamping mechanism 4, and a slide mechanism (corresponding to the slide grinding wheel mechanism of grinding system B). The base is provided with at least one processing station. The processing station is provided with a positioning device 44 and a slide mechanism. The slide mechanism includes a processing component and a calibration probe component 65. The slide mechanism reciprocates along the second direction of the processing station so that the processing component performs processing operations on the material at the processing station. The turret clamping mechanism 4 is provided with a third clamping component 5. The third clamping component 5 is provided with a calibration device 54. The turret clamping mechanism 4 drives the third clamping component 5 to rotate to the processing station. The calibration probe component 65 detects the positioning device 44 and the calibration device 54 respectively to determine the positional offset of the third clamping component 5 relative to the processing station.

[0511] Furthermore, the calibration device 54 is a position calibration reference plate, the positioning device 44 is a position positioning reference plate, and the calibration probe assembly 65 detects the positions of the position positioning reference plate and the position calibration reference plate in the first direction of the machining station, respectively, and determines the displacement difference between the position positioning reference plate and the position calibration reference plate in the first direction of the machining station, so as to determine the position difference between the third clamping assembly 5 on the turret clamping mechanism 4 and the machining station.

[0512] Furthermore, the processing position correction system provided in this embodiment of the invention also includes a transfer centering mechanism 50 provided at the loading and unloading station as described in the foregoing embodiment, so as to complete the centering of the material center with the clamping center of the third clamping component 5 during loading, as the basis for subsequent processing correction. Since it has been described in detail in the foregoing embodiment, it will not be repeated here.

[0513] The correction method of the processing position correction system of the processing equipment in the above embodiment will be described in detail below. The method includes:

[0514] S1. The turret clamping mechanism 4 drives the third clamping assembly 5 to rotate to the processing station corresponding to the third clamping assembly 5;

[0515] S2, the detection and calibration probe assembly 65 of the slide mechanism and the detection and positioning device 44 are used to determine the reference position of the slide mechanism;

[0516] S3. The slide mechanism moves in the radial direction of the turret clamping mechanism 4 toward the third clamping assembly 5 so as to detect the calibration device 54 through the calibration probe assembly 65 to determine the actual position of the third clamping assembly 5.

[0517] S4. Calculate the offset of the slide mechanism based on the reference position of the slide mechanism and the actual position of the third clamping component 5.

[0518] S3. Control the processing components of the slide mechanism to move along the first direction to compensate for the positional offset of the third clamping component 5 at the current processing station, so that the center positions of the two processing components of the slide mechanism coincide with the center position of the material held by the third clamping component 5.

[0519] Specifically, controlling the movement of the processing component of the slide mechanism along the first direction to compensate for the positional offset of the clamping component at the current processing station involves controlling the entire processing component of the slide mechanism to move in the opposite direction of the positional offset along the first direction at the current processing station by a corresponding positional offset. At this time, the distance between the two processing components on the slide mechanism remains fixed, and the distance between the two processing components is the target processing distance of the material to be processed relative to the processing side. Furthermore, the centering operation at the loading and unloading station included in this method has already been described in the foregoing embodiments, and it may further include:

[0520] S01, the turret clamping mechanism 4 drives a third clamping component 5 to rotate to the loading and unloading station, and the second transfer component transfers the material to a third clamping component 5;

[0521] S02, the centering component at the loading and unloading station moves toward a third clamping component 5 along the radial direction of the turret clamping mechanism, and detects the material position through the centering probe component 508.

[0522] S03. The centering component moves synchronously relative to the material along the first direction of the loading and unloading station to perform centering operation on the material.

[0523] S04, The centering probe assembly 508 of the centering component extends to detect the relative distance between the two processing sides of the material.

[0524] The machining position correction system provided in this embodiment of the invention, after the turret clamping mechanism drives the third clamping component 5 to rotate to the machining station, the calibration probe component 65 on the slide mechanism detects the positioning device 44 of the machining station and the calibration device 54 on the third clamping component 5 respectively, to determine the position offset of the third clamping component 5 at the current machining station, so as to compensate for the position offset of the third clamping component 5 by controlling the machining component as a whole to move and offset along the first direction, thereby compensating for the control accuracy of the rotation angle of the turret clamping mechanism 4, and thus improving the machining accuracy of the machining equipment.

[0525] 6. Knife Repair System

[0526] like Figure 41 As shown, in this embodiment of the invention, a tool dressing device 53 is also provided laterally on the third clamping component 5 on the turret clamping mechanism 4. The turret clamping mechanism 4, the third clamping component 5 on the turret clamping mechanism 4, the tool dressing device 53, and the slide grinding wheel mechanism 6 described in the foregoing embodiments together constitute the tool dressing system provided in this embodiment. This tool dressing system can perform tool dressing operations on the grinding device while the slide grinding wheel mechanism 6 is performing a grinding operation on the material clamped by the third clamping component 5, without needing to drive the slide grinding wheel mechanism 6 to the tool dressing position for tool dressing operations. This not only simplifies the equipment structure but also improves grinding efficiency.

[0527] Specifically, in a specific embodiment of the present invention, the second chuck bracket 522 includes a first support portion and a second support portion. The first support portion is connected to the central turret 41, and the second support portion is located radially away from the central turret 41 and connected to the fourth chuck 521. The axial length of the first support portion is greater than that of the second support portion, and the tool trimming device is disposed on the first support portion.

[0528] In a preferred embodiment of the present invention, the horizontal height of the first support is located at the clamping plane of the second clamp, and the tool trimming device 53 is disposed on the first support and is flush with the clamping plane of the second clamp. The tool trimming device 53 includes an oilstone assembly, which includes oilstones disposed opposite to each other on both sides of the first support. The oppositely disposed oilstones can simultaneously perform tool trimming operations on the oppositely disposed grinding wheel assembly 62.

[0529] Furthermore, in a specific embodiment of the present invention, the grinding station includes a rough grinding station and a fine grinding station. At least one third clamping assembly 5 is laterally provided with a rough grinding dressing device, and at least two third clamping assemblies 5 are laterally provided with fine grinding dressing devices. Therefore, in a preferred embodiment of the present invention, a rough grinding dressing device is provided on both sides of one of the third clamping assemblies 5, and a fine grinding dressing device 53 is provided on at least two third clamping assemblies 5, so that the dressing operation of different grinding wheels can be realized simultaneously during the grinding operation.

[0530] 5. Control method of grinding system B

[0531] This invention also provides a control method based on the above-described grinding system B, which specifically includes the following steps:

[0532] S1. The turret clamping mechanism 4 drives the third clamping component 5 to rotate to the corresponding grinding station, and the sliding table grinding wheel mechanism 6 performs grinding operation on the first processing side of the material at the current grinding station.

[0533] S2. The third clamping component 5 drives the material to rotate as a whole, so that the second processing side of the material is set relative to the grinding surface of the slide grinding wheel mechanism 6.

[0534] S3, the sliding table grinding wheel mechanism 6 performs grinding operations on the second processing side of the material at the current grinding station until the grinding operation of the material at the current grinding station is completed.

[0535] The grinding system B provided in this embodiment of the invention, by setting at least two grinding stations on the base and setting a third clamping component 5 on the turret clamping mechanism 4 corresponding to the grinding stations, allows materials at different grinding stations to be ground, thereby improving the processing efficiency of the equipment.

[0536] In a specific grinding operation, the silicon block is ground through one rough grinding and one fine grinding. Therefore, the control method of grinding system B can also specifically include the following steps:

[0537] S11. Control the turret clamping mechanism 4 to rotate, driving a third clamping component 5 to rotate to the rough grinding station. At this time, a third clamping component 5 is located at the fine grinding station, and a third clamping component 5 is located at the loading and unloading station.

[0538] S12. The material on a third clamping assembly 5 is subjected to rough grinding operation at the rough grinding station; the material on a third clamping assembly 5 is subjected to fine grinding operation at the fine grinding station; the transfer and centering mechanism 50 located at the loading and unloading station performs material transfer and centering operation on a third clamping assembly 5.

[0539] S13. Control the turret clamping mechanism 4 to rotate, driving a third clamping component 5 to rotate to the fine grinding station. At this time, a third clamping component 5 is located at the loading and unloading station, and a third clamping component 5 is located at the rough grinding station.

[0540] S14. The material on a third clamping assembly 5 is subjected to rough grinding operation at the rough grinding station; the material on a third clamping assembly 5 is subjected to fine grinding operation at the fine grinding station; the transfer and centering mechanism 50 located at the loading and unloading station unloads the processed material on a third clamping assembly 5 and performs material transfer and centering operations.

[0541] The control method of the grinding system B provided in this embodiment of the invention, by setting at least two grinding stations on the base and setting a third clamping component 5 on the turret clamping mechanism 4 corresponding to the grinding stations, allows the materials at different grinding stations in a processing cycle to be ground, thereby improving the processing efficiency of the equipment.

[0542] III. Plugging and Adhesive System C

[0543] like Figure 42 and Figure 43 As shown, the rod-joining and gluing system C in this invention is used to automatically arrange, glue, and cure small and thin silicon blocks so that multiple small silicon blocks can be automatically integrated into a larger, integral silicon block rod, preparing for the subsequent slicing process.

[0544] These small, thin silicon blocks can be cut from the scrap material generated during the squaring process of silicon rods, or from the head and tail materials generated during the cutting process of silicon rods. Since these scrap materials are typically small and irregularly shaped, the silicon blocks cut from them are characterized by their small size and thinness. To improve subsequent slicing efficiency, multiple small silicon blocks can be spliced ​​and integrated using the splicing and bonding system C of this invention to form a large, long silicon rod, which is then automatically sliced ​​using automated slicing equipment. Of course, similar small silicon blocks generated through other methods can also be spliced ​​and integrated using the splicing and bonding system C of this invention, not limited to those made from scrap material or head and tail materials. Besides silicon rods, other high-hardness and brittle materials, such as sapphire and ceramics, can also be spliced ​​and integrated using the splicing and bonding system C of this invention.

[0545] Specifically, such as Figure 42 and Figure 43 As shown, the silicon ingot bonding system C includes a bonding unit 7, an adhesive coating unit 8, and a curing unit 9 arranged in a cooperative manner. The bonding unit 7 detects whether the silicon ingot size is up to standard and arranges the qualified silicon ingots into a row of silicon ingots of a certain length. The adhesive coating unit 8 transports workpiece plates for bonding small silicon ingots and automatically applies adhesive to the workpiece plates. The curing unit 9 picks up the arranged silicon ingot groups and the adhesive-coated workpiece plates respectively, and bonds and cures them to form silicon ingot rods. The bonding unit 7, adhesive coating unit 8, and curing unit 9 can work simultaneously and in parallel, thereby quickly and automatically integrating multiple silicon ingots into silicon ingot rods that are easy to slice.

[0546] Preferably, the aforementioned splicing and gluing system C is used for the automatic arrangement of multiple small silicon blocks at equal intervals. For silicon blocks assembled from these blocks, gaps form between adjacent blocks. Therefore, during slicing, the dicing mesh used for slicing requires special configuration to ensure its cutting position matches the multiple gaps on the silicon block. The automatic, equally spaced arrangement method makes it easier to configure suitable dicing meshes on the silicon blocks, especially during batch slicing, eliminating the need for repeated readjustment of the dicing mesh, thus further improving production efficiency and ensuring slicing quality.

[0547] Furthermore, such as Figure 44 and Figure 45 As shown, the stacking unit 7 includes a feeding mechanism, a centering platform, and a stacking assembly. The feeding mechanism feeds silicon blocks and automatically detects their thickness during the feeding process. Silicon blocks that meet the thickness standard are transported to the centering platform. The centering platform can hold multiple silicon blocks and can adjust their placement for the first time, transferring multiple silicon blocks simultaneously to the stacking assembly. The stacking assembly picks up multiple silicon blocks from the centering platform and adjusts their placement a second time, reducing the spacing between the silicon blocks. The stacked silicon blocks with adjusted spacing are then placed on the stacking platform. When the stacking assembly adjusts the next group of silicon blocks, it sequentially places the next group in front of or behind the previous group, ensuring continuous placement of the two groups. By repeating the above operations, the feeding mechanism, centering platform, and stacking assembly can arrange multiple small silicon blocks into a row of silicon blocks long enough to be stacked into a complete stack.

[0548] Furthermore, such as Figures 46 to 47 As shown, the material sorting mechanism includes a sorting fixture 71, a detection component 72, a feeding conveyor line 73, and an NG conveyor line 74. The detection component 72 is positioned close to the feeding conveyor line 73. The sorting fixture 71 is movably positioned above the feeding conveyor line 73 and the NG conveyor line 74. The silicon block is placed on the feeding conveyor line 73, which can move the silicon block. When the silicon block moves to the detection component 72, the detection component 72 can detect the thickness of the silicon block and determine whether the thickness is within a preset error range. After the thickness detection is completed, the feeding conveyor line 73 continues to move the silicon block to the sorting fixture 71, which clamps the silicon block, causing it to detach from the feeding conveyor belt. According to the detection results of the detection component 72, if the thickness of the silicon block exceeds the preset error range, it means that the silicon block does not meet the requirements for rod bonding. At this time, the material distribution fixture 71 carries the silicon block to the top of the NG conveyor line 74 and places the silicon block on the NG conveyor line 74. The NG conveyor line 74 can remove the silicon block whose size does not meet the requirements from the material distribution mechanism. If the thickness of the silicon block is within the preset error range, the material distribution fixture 71 will carry the silicon block into the subsequent rod stacking process.

[0549] Furthermore, the material distribution fixture 71 includes a material distribution truss 711, a material distribution slide rail 712, and a material distribution gripper 713. The material distribution truss 711 extends horizontally, the material distribution slide rail 712 extends vertically, and the material distribution gripper 713 is slidably mounted on the material distribution slide rail 712. The material distribution slide rail 712 is slidably mounted on the material distribution truss 711. The material distribution gripper 713 can move vertically up and down along the material distribution slide rail 712, and the material distribution slide rail 712 can drive the material distribution gripper 713 to move horizontally along the material distribution truss 711. The material distribution truss 711 is located above the loading conveyor line 73 and the NG conveyor line 74, so that the material distribution gripper 713 can grip the silicon block on the loading conveyor line 73 and transfer the silicon block to the NG conveyor line 74 or to the centering platform of the assembly unit 7.

[0550] Furthermore, such as Figures 48 to 50 As shown, the material dispensing gripper 713 includes a gripper body 714, a rotating assembly 715, and a third gripper assembly 716. The third gripper assembly 716 is connected to the gripper body 714 via the rotating assembly 715. The third gripper assembly 716 can grip objects, and the rotating assembly 715 can cause the third gripper assembly 716 to rotate, thereby changing the placement direction of the gripped object on the third gripper assembly 716. The gripper body 714 is slidably connected to the material dispensing slide rail 712, which can drive the gripper body 714 and the gripped object on the gripper body 714 to slide up and down along the material dispensing slide rail 712. Specifically, the third gripper assembly 716 includes a first base 717, on which a centering cylinder is provided. A fifth gripper is provided at each end of the centering cylinder. The centering cylinder can drive the two fifth grippers to move closer or further apart to grip objects such as silicon blocks. The rotating assembly 715 includes a rotating shaft, which is connected to the gripper body 714 via a bushing. The first base 717 of the third gripper assembly 716 is fixedly connected to the rotating shaft. The gripper body 714 is also provided with a drive mechanism, such as a motor. The drive mechanism is connected to the rotating shaft via a belt. The drive mechanism can drive the rotating shaft to rotate via the belt, thereby causing the first base 717 and the fifth gripper on the first base 717 to rotate, changing the placement position of the object gripped on the fifth gripper. Preferably, the third gripper assembly 716 is provided with... Figure 48 The first clamping position shown and Figure 49 The second clamping position shown forms a 90-degree angle between the first clamping position and the second clamping position. The first clamping position is set in the horizontal direction, and the second clamping position is set in the vertical direction. The rotating component 715 can drive the third clamping head component 716 to rotate, so as to switch between the first clamping position and the second clamping position.

[0551] The reason why the third chuck assembly 716 in the aforementioned material-separating gripper 713 is set to be rotatable is that the rod-jointing unit 7 and the rod-jointing and sticking system C in this solution are particularly suitable for small silicon blocks processed from scraps such as edge pieces and head / tail materials. Figure 1 As shown, these silicon blocks are typically thin and long, therefore, during the feeding process, a method is used... Figure 51 Transporting silicon blocks in the flat position shown in the diagram provides greater stability. However, during the splicing process, to meet the requirements of wafer slicing, the silicon blocks need to be positioned as follows: Figure 1 As shown, the silicon blocks are arranged vertically along their long sides before being spliced. In this scheme, the silicon blocks are laid flat on the feeding conveyor line 73 for transportation and thickness detection, as shown. Figure 48 As shown, the material distribution gripper 713 picks up the flat silicon block. If the thickness of the silicon block does not meet the preset error range, the material distribution gripper 713 moves directly to the NG conveyor line 74 and places the silicon block down. If the thickness of the silicon block meets the preset error range, then... Figure 49 As shown, the rotating component 715 in the material distribution gripper 713 drives the third gripper component 716 to rotate 90 degrees, so that the silicon block changes from a flat position to a vertical position, and transports the vertically placed silicon block to the centering platform of the splicing unit 7, so as to facilitate the subsequent splicing and sticking operation.

[0552] Furthermore, such as Figures 51 to 56 As shown, the detection component 72 is located near the feeding conveyor line 73 and includes a first detection element 721 and a second detection element 722. The first detection element 721 is located above the feeding conveyor line 73, and the second detection element 722 is located below the feeding conveyor line 73. The positions of the first detection element 721 and the second detection element 722 correspond in the vertical direction. A detection gap 723 is provided on the feeding conveyor line 73. The first detection element 721 and the second detection element 722 are positioned opposite to the detection gap 723. When no silicon block is placed on the conveyor belt, the first detection element 721 and the second detection element 722 are positioned opposite each other through the detection gap 723, and the distance between them can be measured. When the silicon block is placed on the feeding conveyor line 73 for transportation, the silicon block moves to the position of the detection component 72 and blocks the detection gap 723. The second detection element 722 identifies the distance between the lower surface of the silicon block and the second detection element 722 from below the feeding conveyor line 73 through the detection gap 723. At the same time, the first detection element 721 identifies the distance between the upper surface of the silicon block and the first detection element 721 from above the feeding conveyor line 73. The distance between the first detection element 721 and the second detection element 722 is h, the distance between the first detection element 721 and the upper surface of the silicon block is h1, and the distance between the second detection element 722 and the lower surface of the silicon block is h2. The actual thickness H of the silicon block can then be calculated using the data measured by the detection component 72: H = h - h1 - h2. The first detection element 721 and the second detection element 722 are preferably laser sensors.

[0553] Specifically, such as Figure 51 and Figure 54As shown, the feeding conveyor line 73 includes a feeding platform 731, on which two sets of conveyor belts are arranged side by side and move synchronously, forming a detection gap 723 between the two sets of conveyor belts. The feeding platform 731 also has two sets of feeding rollers 732, which are respectively located on both sides of the feeding platform 731, at the outer edges of the two sets of conveyor belts. The distance between the two sets of feeding rollers 732 roughly matches the width of the silicon block. The two sets of rollers extend outwards from the feeding end of the conveyor belt, forming a flared structure. When the silicon block begins to be transported from the feeding end of the conveyor belt, the two sides of the silicon block can slide into contact with the feeding rollers 732 on both sides of the conveyor belt during the movement of the conveyor belt. The two sets of rollers can adjust and restrict the position of the silicon block on the conveyor belt, ensuring that the silicon block is located in the middle position between the two sets of conveyor belts, preventing the silicon block from being tilted or shifted. The flared structure at the ends of the two sets of rollers facilitates the entry of the silicon block into the feeding conveyor line 73.

[0554] During transport, the silicon blocks on the feeding conveyor line 73 have their thickness checked by the detection component 72, and then continue to move to the dispensing fixture 71 for dispensing and gripping. To prevent the silicon blocks from continuously moving out of the gripping position on the feeding conveyor line 73, such as... Figure 54 As shown, a limit block 733 is also provided at the end of the conveyor belt. The limit block 733 is mounted above the two sets of conveyor belts and can prevent the silicon blocks on the conveyor belt from continuing to move.

[0555] Furthermore, since the first detection element 721 and the second detection element 722 in the detection assembly 72 need to cooperate with each other to complete the detection of silicon block thickness, the accuracy requirements for their relative positions are high. In order to facilitate adjustment, the first detection element 721 and / or the second detection element 722 are set to be movable so as to adjust the relative positions between the first detection element 721 and the second detection element 722.

[0556] Specifically, such as Figure 52 and Figure 55 As shown, the detection assembly 72 also includes a fourth bracket 725 and a fifth bracket 724. A first detection element 721 is disposed on the fourth bracket 725, and a second detection element 722 is disposed on the fifth bracket 724. The fourth bracket 725 and the fifth bracket 724 are L-shaped. One end of the fourth bracket 725 is connected to the loading platform 731 of the loading conveyor line 73, and the other end extends from above the loading conveyor line 73 toward the detection gap 723 between the two sets of conveyor belts. One end of the fifth bracket 724 is connected to the loading platform 731 of the loading conveyor line 73, and the other end extends from below the loading conveyor line 73 toward the detection gap 723 between the two sets of conveyor belts, thereby making the first detection element 721 and the second detection element 722 respectively disposed above and below the loading conveyor line 73.

[0557] Preferably, the fifth support 724 is fixedly mounted to the loading platform 731, and the second detection element 722 is fixedly mounted to the fifth support 724, so that the second detection element 722 serves as a fixed reference position. The fourth support 725 includes a first connecting rod and a second connecting rod. The first connecting rod is movably connected to the loading platform 731 and can move along the material transport direction of the loading conveyor line 73 to adjust the connection position. The second connecting rod is perpendicular to the material transport direction. One end of the second connecting rod is connected to the first connecting rod, and the other end is connected to the first detection element 721. The first detection element 721 is movably mounted on the second connecting rod and can move along the second connecting rod to adjust its position. The position of the first detection element 721 can be freely adjusted by the first and second connecting rods so that the first detection element 721 and the second detection element 722 have a suitable relative position for detection, achieving precise control of position and accuracy, and accurately detecting whether the thickness of the silicon block is qualified. Setting the first detection element 721 located at the top to be movable and adjustable makes it easier to adjust the position. Of course, the second detection element 722 can also be set to be movable and adjustable, and the first detection element 721 can be set as the positioning reference position.

[0558] The detection component 72 installed on the feeding conveyor line 73 will automatically detect the thickness of the silicon block moving on the feeding conveyor line 73 and check whether the thickness of the silicon block is within the error range. When the silicon block reaches the detection position of the detection component 72, the laser sensor will automatically calculate the thickness of the silicon block and compare the detected thickness with the required size. If it is within the required size range, it meets the requirements. The silicon block that meets the requirements will be picked up by the sorting fixture 71 and transported to the centering platform. The silicon block that does not meet the requirements will be picked up by the sorting fixture 71 and transported to the NG conveyor line 74.

[0559] The material distribution mechanism in the aforementioned bar-jointing and bonding system C, through the rational design of the distribution fixture, detection component 72, and feeding conveyor line's structure and coordination, enables the material distribution mechanism to automatically complete material feeding, detection, and classified transfer. This high degree of automation improves equipment efficiency and reduces labor costs. By making the detection component 72 position-adjustable, calibration and debugging of the component are facilitated, improving the accuracy of material detection. The rotatable distribution fixture enhances the flexibility of the distribution mechanism, enabling automatic material position adjustment for subsequent material discharge and joining / bonding operations.

[0560] Furthermore, such as Figure 57 As shown, one end of the centering platform is located near the material distribution mechanism, and the other end is located near the rod assembly. The centering platform can receive qualified silicon blocks from the material distribution mechanism, adjust the position of the silicon blocks, and transfer the adjusted silicon blocks to the rod assembly to prepare for the subsequent rod splicing and bonding process.

[0561] Specifically, the centering platform includes a platform support 75, on which two sets of movable slides 76 are mounted. The movable slides 76 can reciprocate on the platform support 75 under the drive of the drive assembly. For example... Figure 58 and Figure 59 As shown, the movable slide table 76 includes a slide table base 761, on which three sets of second centering grippers 762 are arranged side by side. The spacing between adjacent sets of second centering grippers 762 is equal. Each set of second centering grippers 762 is equipped with a detection device 763, preferably a sensor. The dispensing fixture 71 in the dispensing mechanism places the qualified silicon block vertically onto any of the second centering grippers 762 of the movable slide table 76. When the detection device 763 on the second centering gripper 762 detects the silicon block, the second centering gripper 762 starts to work. The two clamps on the second centering gripper 762 push and squeeze the silicon block from both sides, respectively, to achieve the centering operation of the silicon block. The dispensing fixture 71 starts placing silicon blocks from the first set of second centering grippers 762 until all three sets of second centering grippers 762 have silicon blocks placed on them. Figure 57 As shown, two sets of movable slides 76 on the platform support 75 transport silicon blocks in parallel. After the silicon block positions on the three sets of second alignment grippers 762 of the first movable slide 76 are adjusted, the first movable slide 76 slides towards the bar assembly, waiting for the bar assembly to grip the silicon block. At this time, the second movable slide 76 can simultaneously adjust the alignment of the silicon block. After all the silicon blocks on the second movable slide 76 have completed their position adjustments, the second movable slide 76 slides towards the bar assembly, and the first movable slide 76 returns. The two sets of movable slides 76 can move independently without interfering with each other. This setup, with two sets of movable slides 76 transporting silicon blocks alternately and three sets of second alignment grippers 762 adjusting the silicon block positions at multiple stations, significantly improves the working efficiency of the alignment platform.

[0562] During the transfer of the silicon ingot from the dispensing mechanism to the centering platform, the dispensing fixture 71 places the silicon block in the middle position of the second centering jaw 762. The two jaws of the second centering jaw 762 clamp the silicon block from both sides. It can be understood that if the clamped surface of the silicon block is parallel to the clamping surface of the second centering jaw 762, the second centering jaw 762 can completely fit with the clamped surface of the silicon block and push the silicon block when it moves. However, if there is an angular deviation between the dispensing fixture 71 and the second centering jaw 762, causing the clamped surface of the silicon block to be non-parallel and the clamping surface of the second centering jaw 762 to have a large angular deviation, the second centering jaw 762 will push the silicon block off-center during the movement and then clamp it. This will cause the silicon block to be misaligned during the transfer process.

[0563] To solve the above problems, such as Figure 58As shown, the second centering gripper 762 is mounted on the adjusting plate 764, which is rotatably adjustable on the slide base 761. By adjusting the mounting angle of the adjusting plate 764 on the slide base 761, the clamping position of the second centering gripper 762 can be made parallel to the delivery position of the silicon block transferred by the splicing rod fixture, thereby preventing misalignment of the silicon block during centering adjustment. Specifically, the adjusting plate 764 is provided with an arc-shaped connecting hole 765, and a pin is provided in the connecting hole 765. The adjusting plate 764 is connected to the slide base 761 through the cooperation of the pin and the connecting hole 765. The fixed connection position of the connecting hole 765 and the pin can be adjusted. Since the connecting hole 765 is arc-shaped, the adjusting plate 764 can rotate within a certain angle range, realizing fine adjustment of the mounting angle of the adjusting plate 764. Preferably, two connecting holes 765 are provided on the adjusting plate 764, symmetrically arranged at both ends of the adjusting plate 764. Two pins are provided in each connecting hole 765. This arrangement facilitates angle adjustment and ensures the stability of the adjusting plate 764 during installation.

[0564] Specifically, such as Figure 57 As shown, two sets of linear guide rails are arranged side by side on the platform support 75. A slider is provided below the slide base 761 of the movable slide 76, and the slider is slidably connected to the linear guide rails so that the slide base 761 is slidably mounted on the platform support 75. A conveyor belt is also provided on the linear guide rails, and a corresponding conveyor belt clamping member 766 is provided on the slide base 761. Two sets of clamping members 766 are provided, located at both ends of the slide base 761. The clamping members 766 can clamp onto the conveyor belt of the linear guide rails. The conveyor belt can move along the extension direction of the linear guide rails under the drive of the drive component, thereby driving the movable slide 76 to slide back and forth along the linear guide rails. The clamping member 766 includes a fixed plate fixedly connected to the slide base 761 and an adjusting plate movably connected to the fixed plate. A clamping space for clamping the conveyor belt is formed between the adjusting plate and the fixed plate. By adjusting the distance between the adjusting plate and the fixed plate, the clamping strength of the clamping member 766 in clamping the conveyor belt can be adjusted.

[0565] Preferably, each set of linear guides includes two parallel tracks, and two sets of sliders are correspondingly arranged on the slide base 761. The conveyor belt on the linear guide is located above the two tracks and is positioned in the middle of the two tracks. The clamping member 766 is located in the middle of the end of the slide base 761. This arrangement helps to improve the stability of the moving slide 76 during the sliding process.

[0566] Preferably, the width of the adjusting plate and the fixed plate is greater than the width of the conveyor belt on the linear guide rail, and the clamping surfaces of the adjusting plate and / or the fixed plate are provided with anti-slip textures, thereby improving the clamping strength of the clamping member 766.

[0567] Preferably, the second centering grippers 762 on the two sets of movable slides 76 are positioned opposite each other; that is, the second centering grippers 762 on the first movable slide 76 are oriented towards the direction of the second movable slide 76, and the second centering grippers 762 on the second movable slide 76 are oriented towards the direction of the first movable slide 76. This arrangement allows the centering stations on the two sets of movable slides 76 to be closer together at the material distribution mechanism or rod stacking assembly, thereby reducing the distance the material distribution mechanism and rod stacking assembly need to move when transferring silicon rods on the centering platform, further improving work efficiency.

[0568] In the specific implementation of the above-mentioned centering platform, a preferred embodiment is to configure the centering platform with two sets of movable slides 76, each set of movable slides 76 equipped with three sets of second centering grippers 762. This configuration can improve the working efficiency of the equipment while ensuring that the equipment has a smaller size and occupies less space, and at the same time, it can form an efficient working relationship with the upstream material distribution mechanism and the downstream bar stacking assembly. Of course, depending on the actual production needs, three or more movable slides 76 can also be set on the platform support 75, and each movable slide 76 can also be equipped with two or more sets of second centering grippers 762 to improve production efficiency.

[0569] The centering platform in the aforementioned rod-jointing and sticking system C improves transfer efficiency through the alternating reciprocating sliding of dual moving slides 76, enabling better and faster connection between upstream and downstream processes. The multiple centering stations allow for simultaneous position adjustment of multiple clamped objects, further enhancing the platform's efficiency. The second centering gripper is adjustable via an adjustment plate, facilitating angle adjustment and improving the accuracy of position adjustment. The movable connection structure of the slide base on the platform support ensures stable and smooth operation of the moving slides 76 while maintaining work efficiency.

[0570] Furthermore, such as Figure 60 As shown, the bar assembly includes a bar clamp 77 and a bar assembly table 78, as... Figure 63 As shown, multiple silicon blocks are placed side by side on the stacking table 78. The spacing between these silicon blocks is fixed and very small. The function of the stacking clamp 77 is to clamp a group of silicon blocks that have been initially positioned on the centering platform and further reduce the spacing between adjacent silicon blocks. Then, this group of silicon blocks is arranged on the stacking table 78 until they are arranged in a straight line to form a complete rod (the complete rod can be composed of approximately 20 to 30 silicon blocks).

[0571] Specifically, the splicing clamp 77 includes a splicing truss 771, a splicing slide rail 772, and a splicing gripper 773. The splicing truss 771 extends horizontally, the splicing slide rail 772 extends vertically, and the splicing gripper 773 is slidably mounted on the splicing slide rail 772. The splicing slide rail 772 is slidably mounted on the splicing truss 771. The splicing gripper 773 can move up and down vertically along the splicing slide rail 772, and the splicing slide rail 772 can drive the splicing gripper 773 to move horizontally along the splicing truss 771. The splicing truss 771 is located above the splicing table 78 and the centering platform, so that the splicing gripper 773 on the splicing clamp 77 can grip the silicon blocks on the centering platform, adjust the position between the silicon blocks to maintain a certain distance between adjacent silicon blocks, and then transfer and place them on the splicing table 78. The splicing clamp 77 repeats the placement action until a complete splice is formed.

[0572] The splicing bar clamp 773 in the splicing bar clamp 77 includes a second base 774. The second base 774 is provided with a fixed clamp and a movable clamp for clamping the objects. The fixed clamp is fixedly connected to the second base. The movable clamp includes two sets, which are respectively arranged on both sides of the fixed clamp. The two sets of movable clamps can slide on the second base 774 and move from both sides of the fixed clamp toward the fixed clamp to reduce the distance between the objects being clamped.

[0573] Specifically, such as Figures 61 to 62 As shown, the second base 774 is provided with a sixth clamp 775 and two seventh clamps 776. The sixth clamp 775 is fixedly connected to the second base 774 and located in the middle of the second base 774. The two seventh clamps 776 are respectively located on both sides of the sixth clamp 775. The second base 774 is also provided with a bar guide rail, and the two seventh clamps 776 are movably connected to the bar guide rail. The seventh clamps 776 can slide along the bar guide rail to move closer to or further away from the sixth clamp 775. Of course, the seventh clamps 776 can also be slidably connected to the second base 774 using other common sliding structures.

[0574] Preferably, the two seventh chucks 776 form a set of second centering jaws 762, which are driven by a servo centering drive mechanism. The two seventh chucks 776 are centered on the sixth chuck 775 and move towards or away from the sixth chuck 775 in a centering manner. The servo centering drive mechanism can accurately control and position the center position of the two seventh chucks 776 relative to the center position of the sixth chuck 775, thereby accurately controlling the center position of the silicon block on the sixth chuck 775 and the relative position of the two silicon blocks on the seventh chucks 776.

[0575] Preferred, such as Figure 61 and Figure 62As shown, the sixth chuck 775 includes a first driving part and two first clamping parts connected to each other. The first driving part can drive the two first clamping parts to move closer or further apart, thereby clamping or placing the silicon block. The seventh chuck 776 includes a second driving part and two second clamping parts connected to each other. The second driving part can drive the two second clamping parts to move closer or further apart, thereby clamping or placing the silicon block. The second clamping parts of the seventh chuck 776 are provided with extensions 777, which extend toward the location of the first clamping parts of the sixth chuck 775, so that the second clamping parts can be closer to the first clamping parts in the sliding direction of the seventh chuck 776. Preferably, the second clamping parts on the two seventh chucks 776 located on both sides of the sixth chuck 775 adopt this arrangement, that is, the extensions 777 on the two second clamping parts extend toward the first clamping parts from opposite sides of the sixth chuck 775. The above configuration facilitates the adjustment of the minute spacing between adjacent silicon blocks on the bar clamp 773. At the same time, the driving parts between the adjacent sixth clamp 775 and seventh clamp 776 will not interfere with each other during the movement, which is more conducive to the arrangement of silicon blocks.

[0576] The preferred configuration of the ingot clamping jaws 773 is as described above, comprising a fixed sixth clamp 775 located in the center and two movable seventh clamps 776 located on either side, capable of simultaneously clamping three silicon blocks on the centering platform. This configuration improves the efficiency of silicon block stacking, facilitates precise control of the spacing between adjacent silicon blocks, and makes it easier to adjust the spacing between adjacent silicon blocks. Of course, in addition to the preferred configuration described above, the second and third clamps on the ingot clamping jaws 773 can also be movable, and the number of clamps used to hold the silicon blocks can be two or more.

[0577] Furthermore, both the sixth chuck 775 and the seventh chuck 776 are equipped with detection devices, preferably sensors. When the bar clamping jaws 773 in the bar clamping fixture 77 move to the centering platform, the detection devices on the sixth chuck 775 and the seventh chuck 776 detect the silicon block, and the jaws start to work. The first clamping part and the second clamping part clamp the silicon block from the two narrow sides to realize the clamping operation of the silicon block.

[0578] Specifically, such as Figures 63 to 64As shown, the ingot mounting platform 78 includes a support frame 781, on which an ingot mounting substrate 782 for placing silicon blocks is mounted. A buffer pad 783 is mounted on the ingot mounting substrate 782, preferably a nylon buffer pad. The buffer pad 783 can prevent damage to the silicon blocks from impacts while ensuring surface precision. A fixing device is also provided on the ingot mounting substrate 782 to position and fix each silicon block placed on the ingot mounting substrate 782, ensuring the position of the silicon blocks remains constant and preventing them from shaking, tilting, or collapsing.

[0579] The fixing device is preferably an adsorption device 784, which includes multiple vacuum suction cups and a suction cup fixing plate for fixing the vacuum suction cups. When the splicing bar gripper 773 transports the silicon block from the centering platform to the splicing bar stage 78, the multiple vacuum suction cups in the adsorption device 784 can adsorb the bottom of the multiple silicon blocks respectively, thereby positioning and fixing the silicon blocks. After the vacuum suction cups complete the adsorption, the splicing bar gripper 773 releases the silicon block and performs the next round of gripping. After the silicon block assembly on the splicing bar stage 78 is completed, it waits for the adhesive clamp in the curing unit 9 to clamp it to the curing unit 9 for bonding and curing.

[0580] Specifically, a buffer pad 783 is located in the middle of the splicing rod substrate 782. The middle part of the buffer pad 783 has a long strip-shaped hollow structure. Multiple vacuum suction cups are arranged side by side in the hollow structure of the buffer pad 783. The adsorption surface of the vacuum suction cups is roughly flush with the upper surface of the buffer pad 783. When the silicon block is moved to the splicing rod stage 78, the two ends of the lower surface of the silicon block can abut against the buffer pad 783 to ensure that the silicon block is placed stably. The middle part of the lower surface of the silicon block can be adsorbed and fixed by the vacuum suction cups to prevent the silicon block from shifting or tipping over.

[0581] The aforementioned fixing device can also be multiple fixed partitions arranged side by side and spaced apart. The silicon blocks are placed in the gaps between adjacent fixed partitions, and the fixed partitions are used to achieve positioning and discharge and prevent tipping.

[0582] Furthermore, a quantity detection device 785 is also provided on the stacking table 78. The quantity detection device 785 is used to detect the number of silicon blocks placed on the stacking table 78. When the number of silicon blocks reaches the required number of whole rods, the adhesive clamp in the curing unit 9 can clamp and transfer the silicon block assembly. Preferably, the quantity detection component 72 includes a mounting frame 786. One end of the mounting frame 786 is connected to the support frame 781, and the other end extends away from the support frame 781. The sensor for detecting the quantity is located at the end of the mounting frame 786 away from the support frame 781, so that a gap space is formed between the sensor and the support frame 781. The gap space can prevent the stacking claw 773 or the adhesive clamp from interfering with the sensor when placing or clamping silicon blocks.

[0583] In the rod-arranging assembly of the aforementioned rod-jointing system C, two sets of movable clamps are positioned relative to a central fixed clamp, which improves the accuracy of the spacing between the clamped objects and allows for precise control of their relative positions. The specific structural design of the clamps facilitates the adjustment of minute distances between adjacent clamped objects, while preventing interference between adjacent clamps during movement, further enhancing the arrangement of the clamped objects. The fixing device on the rod-jointing platform positions and fixes the material blocks placed on the rod-jointing substrate, ensuring their position remains constant and preventing them from shaking, tilting, or collapsing. A space is created between the quantity detection device on the rod-jointing platform and the platform itself, preventing positional interference between the material block clamps and the detection device when placing or picking up material blocks.

[0584] Furthermore, such as Figure 42 and Figure 43 As shown, the gluing unit 8 includes a workpiece board conveyor line and a gluing device. The workpiece board conveyor line is used to transport the workpiece board, and the gluing device can automatically apply glue to the workpiece board placed on the workpiece board conveyor line. The adhesive clamp in the curing unit 9 can clamp the glued workpiece board onto the curing stage in the curing unit 9, and then clamp the arranged silicon block group and place it on the workpiece board, thereby bonding and curing the workpiece board and the silicon block group to form a silicon block rod that is convenient for subsequent slicing processing.

[0585] Furthermore, such as Figure 65 As shown, the curing unit 9 is located on one side of the adhesive application unit 8, and includes a curing table 91, an adhesive clamp 92, and a curing clamp 93. The adhesive clamp 92 can move to the adhesive application unit 8 to clamp the adhesive-coated workpiece plate, place the workpiece plate on the curing table 91, and then move to the assembly table 78 in the assembly bar unit 7 to grab a set of arranged silicon blocks, place the silicon block set on the adhesive-coated workpiece plate on the curing table 91, and thus bond the silicon block set to the workpiece plate. The adhesive clamp 92 holds the upper part of the silicon block assembly. When the adhesive clamp 92 places the silicon block assembly, the curing clamp 93 set on the curing stage 91 first clamps the lower side of the silicon block assembly. After the curing clamp 93 clamps the silicon block assembly, the adhesive clamp 92 releases the silicon block assembly. This operation is to avoid the problem of each silicon block shifting or tilting on the workpiece plate when the adhesive clamp releases the silicon block assembly. The curing clamp 93 can continuously clamp the silicon blocks during the process of bonding and curing the silicon block assembly with the workpiece plate, ensuring that each silicon block is combined with the workpiece plate at the preset position, and finally obtains a silicon block rod that meets the requirements.

[0586] Specifically, such as Figure 68As shown, the curing table 91 includes a support base 911, on which a curing station and a pressure block placement platform are provided. A curing fixture 93 is positioned at the curing station, and a pressure block 912 is placed on the pressure block placement platform. After the curing fixture 93 clamps the silicon block assembly, the adhesive fixture 92 releases the silicon block and then picks up the pressure block 912 from the pressure block placement platform, placing it on top of the silicon block assembly to press down on the silicon block. Under the gravity of the pressure block 912, the silicon block makes full contact with the adhesive on the workpiece plate, completing the bonding and curing process. The curing table 91 is also equipped with positioning pins that mate with the workpiece plate for positioning the workpiece plate during placement. The support base 911 has two or more curing stations to facilitate the simultaneous bonding and curing of multiple sets of silicon blocks, improving work efficiency.

[0587] like Figure 65 and Figure 66 As shown, the adhesive clamp 92 includes an adhesive truss 921, an adhesive slide rail 922, and an adhesive gripper 923. The adhesive truss 921 extends horizontally, the adhesive slide rail 922 extends vertically, and the adhesive gripper 923 is slidably mounted on the adhesive slide rail 922. The adhesive slide rail 922 is slidably mounted on the adhesive truss 921. The adhesive gripper 923 can move up and down vertically along the adhesive slide rail 922, and the adhesive slide rail 922 can drive the adhesive gripper 923 to move horizontally along the adhesive truss 921. The adhesive truss 921 is located above the curing stage 91 and the splicing stage 78, so that the adhesive gripper 923 on the adhesive clamp 92 can pick up the silicon block assembly on the splicing stage 78 and place it on the curing stage 91, or pick up the pressure holding block 912 on the curing stage 91 to perform pressure holding operation, or remove the silicon block rod that has been bonded and cured on the curing stage 91.

[0588] Specifically, such as Figure 67 , Figures 70 to 76 As shown, the adhesive clamp can be used to clamp two or more different objects. The adhesive gripper 923 in the adhesive clamp 92 includes a first clamping mechanism and a second clamping mechanism. The first clamping mechanism is driven by a first driving member and can open or close in a first direction to clamp objects, forming a first clamping space for clamping objects. The second clamping mechanism is driven by a second driving member and can open or close in a second direction to clamp objects, forming a second clamping space for clamping objects. The first direction and the second direction are different directions. Preferably, the first direction and the second direction are perpendicular to each other in the horizontal direction. The first clamping space and the second clamping space are overlapped, and the first clamping mechanism and the second clamping mechanism can clamp different objects.

[0589] Due to differences in clamping direction and specific clamping structure, the first clamping mechanism and the second clamping mechanism can be used to clamp two or more different objects. In this embodiment, the first clamping mechanism is used to clamp multiple silicon blocks arranged side by side, and the second clamping mechanism is used to clamp the workpiece plate, the pressure holding block 912, and the silicon block rod formed by bonding and curing the workpiece plate and multiple silicon blocks together. The first clamping space and the second clamping space overlap, allowing the adhesive gripper 923 to fully utilize the clamping space on the adhesive gripper 923 while being able to clamp multiple objects. This increases the gripping function of the adhesive gripper 923 while reducing its size and space occupation.

[0590] Furthermore, the first clamping mechanism is used to clamp multiple silicon blocks simultaneously. Since the dimensions of the multiple silicon blocks are different, in order to ensure that the multiple silicon blocks can be clamped stably and not damaged, the first clamping mechanism includes a first fixed clamping part 924 and a plurality of first elastic clamping parts 925. The first fixed clamping part 924 and the plurality of first elastic clamping parts 925 are positioned opposite each other, and each silicon block corresponds to one first elastic clamping part 925. The first fixed clamping part 924 is provided with a positioning reference surface, and the first elastic clamping part 925 is elastically clamped. Under the drive of the first driving member, the first fixed clamping part 924 and the first elastic clamping part 925 can move relative to each other. One side of the silicon block abuts against the positioning reference surface of the first fixed clamping part 924 to realize the positioning of the relative positions of multiple silicon blocks. The other side of the silicon block abuts against the first elastic clamping part 925. Since the first elastic clamping part 925 is elastically clamped, each first elastic clamping part 925 will apply appropriate clamping force according to the actual size of its corresponding silicon block to ensure that multiple silicon blocks are stably clamped at the same time and are not damaged.

[0591] Specifically, such as Figure 67 and Figure 71 As shown, the first fixed clamping part 924 includes an elongated first pad, the clamping surface of which is a plane, which can form a positioning reference plane. The first clamping mechanism also includes a clamping base plate 926, which is positioned opposite to the first fixed clamping part 924. The first elastic clamping part 925 includes a second pad 927 and a spring, one end of which is connected to the clamping base plate 926 and the other end is connected to the second pad 927. The springs of the multiple first elastic clamping parts 925 and the second pads 927 are arranged side by side on the clamping base plate 926. When the first clamping mechanism clamps the silicon block assembly, the spring in the first elastic clamping part 925 can provide elastic buffering when the second pad 927 squeezes the sidewall of the silicon block, providing corresponding clamping force compensation for different sizes of different silicon blocks.

[0592] Preferred, such as Figure 67As shown, each first elastic clamping part 925 includes two sets of springs, which are arranged vertically and vertically to connect to the upper and lower ends of the second pad 927 respectively. This arrangement helps to improve the clamping force compensation effect and the clamping stability.

[0593] Preferably, the first pad and the second pad 927 are nylon pads.

[0594] In addition to the preferred configuration described above, the spring in the first elastic clamping part 925 can also be replaced with an elastic metal spring, or the spring and the second pad 927 can be replaced with a silicone pad that can provide elastic clamping, etc.

[0595] Specifically, such as Figure 70 As shown, the second clamping mechanism in the adhesive gripper 923 includes two opposing fourth grippers 928. A second driving member can drive the two fourth grippers 928 to move relative to each other to achieve a clamping action. The two fourth grippers 928 are respectively located at the two ends of the first clamping mechanism; that is, the two fourth grippers 928 face the silicon blocks located at both ends of the silicon block assembly on the first clamping mechanism. Figure 75 As shown, the extension length of the lower end of the fourth gripper 928 exceeds the extension length of the lower end of the first gripping mechanism. This arrangement can increase the gripping range of the second gripping mechanism, making it convenient to grip various objects such as workpiece plates and pressure holding blocks 912, and avoid motion interference with the first gripping mechanism.

[0596] Preferably, a protruding structure 929 is also provided on the inner side of the lower end of the fourth gripper 928. The middle part of the protruding structure 929 is concave and the two ends are convex to form a clamping groove. When the fourth gripper 928 clamps the workpiece plate or the pressure plate, the clamped object can be clamped in the clamping groove, thereby improving the clamping stability and avoiding the clamped object from loosening and causing processing accidents.

[0597] In the aforementioned adhesive gripper 923, the first driving member and the second driving member can be a cylinder guide rod mechanism, that is, a drive system consisting of a gear linkage assembly, a connecting rod and a cylinder; or, a servo centering drive mechanism, that is, a drive system consisting of a servo motor, a reducer and a ball screw.

[0598] The adhesive gripper 92 in the aforementioned rod-bonding system C is a composite robotic arm. By simultaneously setting up a first gripping mechanism and a second gripping mechanism, it achieves the technical effect of individually picking up and placing multiple silicon blocks, workpiece boards, pressure-holding blocks 912, and bonded and cured silicon rods. The composite configuration of the two grippers allows the adhesive gripper to be used to grip two or more different objects, and the two grippers share a single gripping space, greatly reducing the size and space occupied by the adhesive gripper, and making it easier to move within the rod-bonding system C. The combination of a fixed gripping part and an elastic gripping part ensures that when gripping multiple material blocks simultaneously, it can accurately position the gripping position, adapt to dimensional deviations between material blocks, provide clamping force compensation, ensure gripping stability, and prevent damage to the material blocks.

[0599] Furthermore, the curing fixture 93 in the curing unit 9 is set on the curing stage 91, and a corresponding curing fixture 93 is set at each curing station on the curing stage 91. The curing fixture 93 is used to connect with the adhesive stick fixture, and to take the multiple silicon blocks to be spliced ​​and bonded from the adhesive fixture 92, ensuring that the multiple silicon blocks do not shift or tip over during the transfer process. The curing fixture 93 continuously holds the silicon blocks during the bonding and curing process between the multiple silicon blocks and the workpiece board until curing is completed.

[0600] Similar to the adhesive clamp 92, the curing clamp 93 also needs to clamp multiple silicon blocks simultaneously. Since the dimensions of the silicon blocks differ, to ensure that all silicon blocks are stably clamped and not damaged, such as... Figures 77 to 80 As shown, the curing fixture 93 includes a second fixed clamping part 931 and a plurality of second elastic clamping parts 932. The second fixed clamping part 931 and the plurality of second elastic clamping parts 932 are positioned opposite each other, with each silicon block corresponding to one second elastic clamping part 932. The second fixed clamping part 931 is provided with a positioning reference surface. The second elastic clamping parts 932 are elastic clamps, and the second fixed clamping part 931 and the second elastic clamping parts 932 can move relative to each other to clamp the silicon block. One side of the silicon block abuts against the positioning reference surface of the second fixed clamping part 931 to achieve positioning of the relative positions of the plurality of silicon blocks. The other side of the silicon block abuts against the second elastic clamping part 932. Since the second elastic clamping part 932 is elastic, each second elastic clamping part 932 will apply an appropriate clamping force according to the actual size of its corresponding silicon block to ensure that the plurality of silicon blocks are stably clamped at the same time without being damaged.

[0601] Furthermore, such as Figure 77As shown, a curing platform is provided between the second fixed clamping part 931 and the plurality of second elastic clamping parts 932. The workpiece plate coated with adhesive is placed on the curing platform, and the silicon block assembly is placed on the workpiece plate. Since the adhesive usually has a certain degree of fluidity, the thickness of the adhesive on the workpiece plate may be uneven. In order to ensure that each silicon block in the silicon block assembly can make full and tight contact and bond with the workpiece plate and the adhesive, it is necessary to push and compress the silicon block from the top, for example, by using a pressure plate to press the silicon block. Based on this, the second fixed clamping part 931 and the second elastic clamping part 932 move relative to each other in the horizontal direction to clamp the silicon block. The second fixed clamping part 931 and the second elastic clamping part 932 are configured to roll and clamp in the vertical direction. When the silicon block is subjected to its own weight, the pressure of the pressure block 912, or other forces, the silicon block can move slightly downward in the vertical direction while keeping its position relatively unchanged in the horizontal direction, so as to enhance the tight contact with the workpiece plate and the adhesive.

[0602] Specifically, such as Figure 78 As shown, the second clamping mechanism includes a first substrate 933 and a second substrate 934 disposed opposite to each other. A second fixed clamping part 931 is disposed on the first substrate 933, and a second elastic clamping part 932 is disposed on the second substrate 934. The second fixed clamping part 931 includes an elongated roller 935 disposed on the first substrate 933. The axis of the roller 935 extends in the transverse direction so that the roller 935 can roll in the vertical direction. Since the position between the first substrate 933 and the roller 935 is relatively fixed, the surface of the roller 935 tangent to the silicon block can form a positioning reference surface. The second elastic clamping part 932 includes a roller 936 and a spring. One end of the spring is connected to the second substrate 934, and the other end is connected to the roller 936. The springs and rollers 936 of the multiple second elastic clamping parts 932 are arranged side by side on the second substrate 934. When the second clamping mechanism clamps the silicon block assembly, the spring in the second elastic clamping part 932 can provide elastic buffer when the roller 936 squeezes the side wall of the silicon block, and provide corresponding clamping force compensation for different sizes of different silicon blocks. At the same time, the silicon block can be slightly adjusted in the vertical direction under the clamping of the roller 935 and the roller 936.

[0603] Preferred, such as Figure 79 As shown, each second elastic clamping part 932 includes two sets of springs, which are arranged vertically and vertically to connect to the upper and lower ends of the roller 936 respectively. This arrangement helps to improve the clamping force compensation effect and the clamping stability.

[0604] In addition to the preferred configuration described above, the spring in the second elastic clamping part 932 can also be replaced with an elastic metal spring, or the spring and roller 936 can be replaced as a whole with a silicone roller 936 that can provide elastic clamping, etc.

[0605] Preferred, such as Figure 78 and Figure 80 As shown, the second fixing clamping part 931 has two or more rollers 935, and a roller is provided at the joint between adjacent rollers 935. Because the second fixing clamping part 931 is relatively long, when the rollers 935 are set as a single unit, the middle of the roller 935 is prone to deformation when clamping the silicon block, resulting in insufficient clamping of the silicon block. Therefore, the rollers 935 are set as two or more, with their ends connected to form a long strip-shaped roller assembly. This arrangement allows each individual roller 935 to be shorter, reducing deformation and ensuring sufficient clamping of the silicon block. To ensure that the joint between two adjacent rollers 935 does not affect the clamping effect, a roller is provided at the joint, which avoids the problem of insufficient clamping force at the joint.

[0606] Preferably, in order to accommodate the arrangement and clamping of silicon blocks of different specifications, the second elastic clamping part 932 is configured as a detachable and replaceable structure, and the number of rollers and the roller spacing distance on different second elastic clamping parts 932 are different to match silicon blocks of different specifications.

[0607] The curing fixture in the aforementioned stick-binding system C employs a combination of fixed and elastic clamping parts. This ensures accurate positioning of the clamping position when simultaneously gripping multiple material blocks, while also accommodating dimensional deviations between the blocks, providing clamping force compensation, guaranteeing clamping stability, and preventing damage to the material blocks. The fixed and elastic clamping parts utilize a rolling clamping method in the vertical direction, allowing the material blocks to remain relatively stationary horizontally while moving slightly downwards vertically to enhance the tight contact between the material blocks and the workpiece plate and adhesive.

[0608] Furthermore, such as Figure 42 and Figure 43As shown, the pegboard system C also includes a truss assembly 60, which is mounted above the pegboard unit 7, the adhesive application unit 8, and the curing unit 9. The truss assembly 60 extends horizontally along the X-axis. The pegboard truss 771 in the pegboard clamp 77 and the adhesive truss 921 in the adhesive clamp 92 are mounted on the truss assembly 60 and can slide back and forth along the truss assembly 60 in the X-axis direction. The pegboard truss 771 and the adhesive truss 921 extend horizontally along the Y-axis. The pegboard slide rail 772 is mounted on... On the piecing bar truss 771, a sliding bar slide rail 922 is mounted on the piecing bar truss 921 and can slide back and forth along the Y-axis. The piecing bar slide rail 772 and the piecing bar slide rail 922 extend vertically along the Z-axis. The piecing bar gripper 773 is mounted on the piecing bar slide rail 772 and can slide back and forth along the Z-axis. The piecing bar gripper 923 is mounted on the piecing bar slide rail 922 and can slide back and forth along the Z-axis. The X, Y, and Z axes are perpendicular to each other, allowing the piecing bar gripper 773 and the piecing bar gripper 923 to move independently or in parallel in three-dimensional space, flexibly gripping objects.

[0609] The rod-jointing and bonding system C in this solution, through a rational configuration of the material distribution mechanism, centering platform, rod-arranging assembly, curing stage, adhesive clamps, and curing clamps, can automatically, quickly, and efficiently achieve the positioning and arrangement of silicon blocks. This prevents the silicon blocks from shifting or tipping over on the workpiece plate when the adhesive clamps release them. The curing clamps continuously hold the silicon blocks during the bonding and curing process, ensuring that each silicon block is bonded to the workpiece plate at its preset position, ultimately resulting in silicon rods that meet the requirements. Furthermore, the rod-jointing and bonding system C can automatically arrange silicon rods at equal intervals, making it easier to configure suitable cutting meshes during subsequent slicing processing. The cutting meshes do not need repeated readjustments, further improving production efficiency and ensuring slicing quality.

[0610] This solution also discloses a method for attaching and splicing sticks, such as... Figure 81 As shown, it specifically includes:

[0611] S1. Feed the material blocks, check whether the material blocks are qualified, and divide the material blocks according to the test results.

[0612] Material blocks are fed through a feeding conveyor line. During the feeding process, the thickness of the material blocks is checked. Material blocks that do not meet the thickness requirements are remo...
