Description

Technical Field

[0001] This invention relates to the field of edge silicon material processing technology, and particularly to a method for bonding edge silicon blocks to rods. Background Technology

[0002] With the development of the photovoltaic industry, the demand for silicon wafers for photovoltaic solar panels is increasing. Silicon wafers are typically manufactured from silicon rods through processes such as opening, grinding, and slicing. Simultaneously, with industry development, competition is intensifying, making cost reduction and efficiency improvement a trend for enterprises. During the silicon rod opening process, edge silicon material is generated. To fully utilize raw materials, this edge silicon material undergoes secondary processing, being cut into edge silicon blocks of different sizes. These blocks are then bonded together to form rods before subsequent slicing and other processing steps. However, in existing edge silicon block processing technologies, due to time constraints in adhesive application, two people typically work together to first bond the edge silicon blocks into segments, and then bond two segments together to form a rod. This bonding method is inefficient and cannot guarantee the perpendicularity of the bonded silicon rod. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention provides a method for bonding edge silicon blocks to rods. This method involves first initially positioning and bonding the edge silicon blocks, then pressing and fixing the sides of the edge silicon wafers, and finally bonding them into rods by pressing from the top. This method is simple to operate, uses inexpensive equipment, and effectively improves the efficiency of rod bonding and ensures the verticality of the bonded rods.

[0004] This invention provides a method for attaching rods to edge-skin silicon blocks, comprising the following steps:

[0005] S1. Place the first edge silicon block onto the base assembly, and then apply glue to its top surface;

[0006] S2. Place the second edge silicon block on the adhesive surface of the first edge silicon block, and apply adhesive to the top surface of the second edge silicon block. Repeat this process for the third edge silicon block, the fourth edge silicon block, and so on, until the placement space inside the base assembly is filled. Stop applying adhesive to the top surface of the top edge silicon block and complete the stacking of the edge silicon blocks.

[0007] S3. Press the stacked edge silicon blocks together from the width and length directions of the sides, and fix the side pressing assembly used for pressing.

[0008] S4. After pressing the stacked edge silicon blocks from the side, press them in the thickness direction through the top pressing component. After standing for a period of time, the edge silicon blocks are glued together.

[0009] A further optimization of the technical solution of the present invention is that the method for determining whether the placement space inside the base assembly is filled in step S2 is that the bottom height of the last edge silicon block is less than the top height of the base assembly.

[0010] In a further optimization of the technical solution of the present invention, the settling time in step S4 is 2-3 hours.

[0011] In a further optimization of the technical solution of the present invention, the base assembly includes two mutually perpendicular positioning bases, a first positioning plate and a second positioning plate, and in step S1, the first piece of edge silicon material is placed on the positioning base, and its two adjacent sides are aligned with the first positioning plate and the second positioning plate respectively.

[0012] In a further optimization of the technical solution of the present invention, the top view of the positioning base is horseshoe-shaped or U-shaped, and the bottom surface of the first edge silicon block is in contact with the positioning surface of the horseshoe-shaped or U-shaped block respectively.

[0013] A further optimization of the technical solution of the present invention is that the positioning base, the first positioning plate and the second positioning plate have silicon material contact plates, and the silicon material contact plates are made of nylon material.

[0014] In a further optimization of the technical solution of the present invention, the side clamping component is hinged to the first positioning plate and / or the second positioning plate, and a quick clamping device is provided between the corresponding positioning plate; the clamping method of the side clamping component in step S3 is as follows: rotate the side clamping component to the side of the stacked edge silicon blocks, and then fix it by quick clamping so that it is pressed tightly on all the edge silicon blocks.

[0015] In a further optimization of the technical solution of the present invention, the side clamping assembly includes a pressing plate and an L-shaped connecting plate. The pressing plate is hinged to the positioning plate through the connecting plate, and a quick clamp for pressing the pressing plate is provided between the pressing plate and the positioning plate.

[0016] In a further optimization of the technical solution of the present invention, the quick clamp includes a locking bolt and a locking clamp, and an L-shaped fixed mounting plate is provided on the pressing plate. The locking clamp is connected to the end of the fixed mounting plate away from the pressing plate by the locking bolt.

[0017] In a further optimization of the technical solution of the present invention, the locking clamp includes a clamp seat, a clamp pull rod, and a clamp connecting rod. The clamp seat is fixed on the positioning plate, the clamp pull rod is hinged to the clamp seat, and a power handle is provided at one end of the clamp connecting rod away from the clamp seat. One end of the clamp connecting rod is hinged to the middle of the clamp pull rod, and the other end is connected to the fixed mounting plate through the locking bolt.

[0018] In a further optimization of the technical solution of the present invention, the side pressing assembly further includes a pressure roller assembly, which is disposed on the pressing plate. Correspondingly, in step S3, after the side pressing assembly presses the stacked edge silicon material, the pressure roller assembly presses and fixes each edge silicon block to ensure that the side of the edge silicon block is aligned with the first positioning plate and the second positioning plate.

[0019] In a further optimization of the technical solution of the present invention, the pressure roller assembly includes a control handle, an adjusting stud, a control shaft, a telescopic frame, and a pressure roller mechanism. The control handle is connected to the adjusting stud. One end of the control shaft is threaded onto the adjusting stud, and the other end is connected to the telescopic frame. Under the control of the control handle, the control shaft can move on the adjusting stud to adjust the extension and retraction of the telescopic frame. The pressure roller mechanism is fixed to the telescopic frame via a guide shaft.

[0020] In a further optimization of the technical solution of the present invention, the pressure roller mechanism includes a positioning handle, a guide shaft, and a pressure roller unit. The positioning handle and the pressure roller unit are respectively disposed at both ends of the guide shaft, and the positioning handle is located on the outside of the pressing plate. The pressure roller unit is located on the inside of the pressing plate and contacts the edge silicone block. A rectangular spring is disposed on the guide shaft between the pressure roller unit and the pressing plate.

[0021] In a further optimization of the technical solution of the present invention, the top pressing assembly includes a support base, a pressure bearing plate, and a linear motion module. The linear motion module is vertically movable and is mounted on the support base, and the pressure bearing plate is fixedly mounted at the bottom end of the linear motion module.

[0022] In a further optimization of the technical solution of the present invention, the linear motion module includes a floating support plate, a support rod, and a moving lead screw. The floating support plate is parallel to the support base, and the support rod is parallel to the moving lead screw. The moving lead screw is mounted on the floating support plate and the support base via a power handle. The power handle can control the moving lead screw to move up and down on the support base, thereby driving the movement of the pressure bearing plate mounted at the bottom of the moving lead screw and the support rod.

[0023] Compared with the prior art, the advantages of the technical solution of the present invention are as follows:

[0024] By initially positioning the edge silicon blocks on the base assembly and then applying adhesive to stack them, work efficiency is improved and the difficulty of the bonding process is reduced. In addition, by pressing and fixing the stacked edge silicon blocks from the sides and top, the firmness of the bonded silicon rod can be improved, and the verticality of the bonded silicon rod can be guaranteed, thereby reducing the difficulty of subsequent processing.

[0057] The following will be combined with the appendix Figure 1-19 The present invention will be further described below.

[0058] To address the problems existing in the prior art, this technical solution is as follows: Figure 1 As shown, a method for attaching rods to edge silicon blocks is proposed, which specifically includes the following steps:

[0059] S1. Place the first edge silicon block onto the base assembly, aligning its two sides with the first and second positioning plates of the base assembly, and then apply glue to its top surface.

[0060] S2. Based on step S1, place the second edge silicon block on the adhesive surface of the first edge silicon block, and apply adhesive to the top surface of the second edge silicon block. Place the third edge silicon block, the fourth edge silicon block, and so on until the placement space inside the base assembly is filled. Specifically, when the bottom height of the last edge silicon block is less than the height of the top of the positioning plate in the base assembly, stop applying adhesive to the top surface of the top edge silicon block and complete the stacking of edge silicon blocks.

[0061] S3. Press the stacked edge silicon blocks together from the width and length directions of the sides, and fix the side pressing assembly used for pressing.

[0062] S4. After pressing the stacked edge silicon blocks from the side, press them in the thickness direction using the top pressing component. After standing for 2-3 hours, the edge silicon blocks are successfully glued.

[0063] Specific examples Figure 2 As shown, the base assembly 1 used in the above-mentioned edge silicon block adhesive rod method includes a fixed base plate 17 and a positioning device. The positioning device is fixedly mounted on the fixed base plate 17, and the positioning device includes a first positioning plate 11 and a second positioning plate 12 that are perpendicular to each other. The first positioning plate 11 and the second positioning plate 12 are both perpendicular to the fixed base plate 17. When the edge silicon block is placed in step S1, the sides of its two beams are aligned with the first positioning plate 11 and the second positioning plate 12 respectively. The second block, the third block, etc. are aligned with the positioning plates corresponding to the positioning device in sequence, ensuring the verticality of the adhesive rod.

[0064] like Figure 3 As shown, a fixing device is provided on the fixed base plate 17, which can be used to adjust the counterweight of the fixed floor and fix it to the ground or counterweight plate with screw sleeves, thereby increasing the stability of the device; preferably, the fixing device is a fixing screw 171, and the number of fixing screws 171 is at least two.

[0065] Lifting screws 16 are also provided on the fixed base plate 17. There are at least two lifting screws 16, which facilitates lifting during equipment operation and reduces the difficulty of handling. Correspondingly, lifting screws 16 are also provided at the top of the position where the first positioning plate 11 and the second positioning plate 12 intersect perpendicularly, which can improve the stability of the lifting process.

[0066] like Figure 2 and Figure 4As shown, the first positioning plate 11 and the second positioning plate 12 are integrally formed to reduce installation errors and increase the strength, rigidity, and stability of the device. Preferably, the positioning base 15, the first positioning plate 11, and the second positioning plate 12 are integrally formed. A first silicon material contact plate 13 is provided on each of the two on opposite sides. The first silicon material contact plate 13 has silicon material contact convex surfaces on both sides in the vertical direction to facilitate the positioning of the edge silicon material. Preferably, the first silicon material contact plate 13 is a nylon plate, which has a lower hardness and a smaller coefficient of friction than metal, thus reducing damage to the edge silicon material.

[0067] In addition, the positioning device also includes a positioning base 15, which is disposed on the fixed base plate 17 and located between the first positioning plate 11 and the second positioning plate 12. The top view of the positioning base 15 is horseshoe-shaped or U-shaped, and the height of the positioning base 15 facilitates the placement and removal of the edge silicon material. Similar to the design of the positioning plate, a second silicon material contact plate 14 is provided on the positioning base 15. Preferably, the second silicon material contact plate 14 is made of nylon material.

[0068] The method of using the base assembly 1 in this device is as follows: fix the base plate 17 on the bottom surface to make it stable, then place the edge silicon material on the positioning base 15, aligning its two sides with the first positioning plate 11 and the second positioning plate 12 respectively, then apply glue to the upper surface of the edge silicon material, place the second edge silicon material in the same way, and so on, until the placed edge silicon material is close to the height of the positioning device, thus completing the sticking process.

[0069] Based on the base assembly 1, in order to increase the firmness and verticality of the adhesive stick, the technical solution of the present invention also provides, as follows: Figure 5 The device shown is a silicone sticking device with a base assembly 1, which has a pressing component on it. The pressing component can be set on the top of the positioning device or on the side opposite to the first positioning device and the second positioning device. Preferably, the pressing component is set on both the top and the side.

[0070] like Figure 6 As shown, the side pressing component 2 of the pressing assembly in this invention is hinged to the positioning device. Specifically, the side pressing component 2 includes a pressing component in the length direction and a pressing component in the width direction. Specifically, the pressing component in the length direction is hinged to the outer surface of the first positioning plate 11, and the pressing component in the width direction is hinged to the outer surface of the second positioning plate 12. Furthermore, the pressing plate 23 of the width direction pressing component 21 is parallel to the first positioning plate 11, and the pressing plate 23 of the length direction pressing component 22 is parallel to the second positioning plate 12.

[0071] like Figure 8As shown, the side clamping assembly 2 includes a pressing plate 23 and a connecting plate 26. The pressing plate 23 is hinged to the corresponding positioning plate of the positioning device via the connecting plate 26. The connecting plate 26 can be an L-shaped plate or an arc-shaped plate, and the connecting plate 26 is fixed to the positioning plate via a hinge base. A quick clamp 4 is provided between the pressing plate 23 and the positioning plate to press the pressing plate 23 tightly.

[0072] The hinge base is a U-shaped seat mounted on a vertical positioning plate. A hinge shaft is provided on the opening of the U-shaped seat. The connecting plate 26 is rotatably connected to the hinge shaft to facilitate the movement of the side clamping assembly 2 away from and towards the positioning device. The hinge base is fixed to the corresponding positioning plate by countersunk screws.

[0073] like Figure 7 and Figure 8 As shown, the quick clamp 4 includes a fixed mounting plate 45, a locking bolt 44, and a locking clamp. The fixed mounting plate 45 is integrally formed with the pressing plate 23 and is located in the middle of the pressing plate 23. Pulling the fixed mounting plate 45 facilitates the overall balanced force on the pressing plate 23. The locking clamp is connected to the fixed mounting plate 45 through the locking bolt 44, and the locking clamp controls the fixed mounting plate 45 to drive the pressing plate 23 to press in the direction corresponding to the vertical plane of the silicon material.

[0074] Preferably, the mounting plate 45 is an L-shaped plate, and the locking bolt 44 is fixed to the side of the mounting plate 45 perpendicular to the pressing plate 23 by threads. By pulling the locking bolt 44 with locking clamps, the side plate of the mounting plate 45 is subjected to force. Due to its own rigidity, the other side of the L-shaped mounting plate 45 will generate a lateral rotation force, so that the pressing plate 23 is pressed tightly against the surface of the edge silicon rod.

[0075] like Figure 7 As shown, the locking clamp includes a clamp seat 41, a clamp pull rod 42, and a clamp connecting rod. The clamp seat 41 is fixed to the positioning plate, the clamp connecting rod is hinged to the clamp seat 41, and the clamp pull rod 42 is hinged to the middle of the clamp connecting rod. A power handle 31 is provided at the end of the clamp connecting rod away from the clamp seat 41, and a locking bolt 44 is fixed to the clamp pull rod 42. Its working principle is as follows: by pushing the power handle 31, the clamp connecting rod rotates around the hinge axis with the clamp seat 41. During the rotation, the clamp pull rod 42 is displaced in a direction parallel to the positioning plate, thereby driving the fixed mounting plate 45 through the locking bolt 44 to provide a directional pressing force to the pressing plate 23.

[0076] For the side clamping assembly 2, in order to vertically process the bonded edge silicone rod, such as... Figure 9 and Figure 10 As shown, a pressure roller assembly is also provided on the side pressing assembly 2. The pressure roller assembly is adjustablely set on the pressing plate 23 via the first guide groove 232. Each pressure roller assembly is provided with several pressure roller mechanisms 25, and each pressure roller mechanism 25 corresponds to a piece of edge silicon material. By pulling / pushing the pressure roller mechanism 25, the corresponding piece of edge silicon material can be adjusted to align with the upper and lower pieces of edge silicon material and be close to the positioning plate.

[0077] Specifically, the pressure roller assembly includes a tension adjustment mechanism 24 and at least two pressure roller mechanisms 25. All the pressure roller mechanisms 25 are slidably disposed in the first guide groove 232 along the height direction via the tension adjustment mechanism 24, so as to align the pressure roller mechanism 25 with the center of a single edge silicon material.

[0078] like Figure 9 and Figure 12 As shown, the tension adjustment mechanism 24 includes a control device 241 and a multi-bar device 242. All the pressure roller mechanisms 25 are mounted on the multi-bar device 242. The multi-bar device 242 is a structure that can extend and retract vertically. The control device 241 is used to control the multi-bar device 242 to extend and retract vertically in the height direction, thereby driving the pressure roller mechanism 25 to adjust its displacement in the vertical direction.

[0079] like Figure 13 and Figure 14 As shown, the multi-bar device 242 includes a telescopic frame 2422 and a support base 2421. The telescopic frame 2422 includes an even number of telescopic connecting rods 2422a, and each telescopic connecting rod 2422a has a hinge hole 2422c in the middle for mounting the pressure roller mechanism 25. Two telescopic connecting rods 2422a form a telescopic unit through the hinge hole 2422c, and all the telescopic units are hinged together. That is, each telescopic unit consists of two telescopic connecting rods 2422a hinged in the middle. After the pressure roller mechanism 25 is installed, the guide shaft 254 of the pressure roller mechanism 25 serves as the central hinge shaft of the two telescopic connecting rods 2422a. For ease of description, the two telescopic links 2422a in the telescopic unit are named the first link and the second link. Specifically, the upper end of the first link of the lower telescopic unit is hinged to the lower end of the second link of the upper telescopic unit, and the upper end of the second link of the lower telescopic unit is hinged to the lower end of the first link of the upper telescopic unit, and so on.

[0080] In this embodiment, one end of the telescopic frame 2422 is fixedly mounted on the pressing plate 23 via the bracket 2421, while the other end of the telescopic frame 2422 is freely disposed. Figure 15As shown, the support base 2421 includes a body 2421a and two fixing blocks 2421b. The two fixing blocks 2421b are respectively disposed on two opposite corners of the body 2421a, corresponding to the first and second connecting rods of the bottom telescopic unit, facilitating connection. The inner sides of the two fixing blocks 2421b are respectively provided with mounting grooves 2421c, and the bottom ends of the first and second connecting rods are respectively provided with miniature cam bearings 2422b adapted to the mounting grooves 2421c. The miniature cam bearings 2422b are disposed within the mounting grooves 2421c to achieve a rotatable connection between the telescopic connecting rod 2422a and the support base 2421.

[0081] like Figure 16 As shown, in order to increase the stability of the bracket 2421 installation, one end of the pressing plate 23 extends inward to a support plate 231 perpendicular to it. The body 2421a is fixedly mounted on the support plate 231. The body 2421a of the bracket 2421 is connected to the support plate 231 by screws, and the fixing direction is consistent with the force direction, which can ensure the stability of the installation.

[0082] See attached document Figure 11 As shown, the control device 241 includes a control handle 2411, an adjusting stud 2412, and a control shaft 2413. The adjusting stud 2412 is fixedly mounted on the pressing plate 23 via a fixing seat, specifically including a bottom fixing seat 2415 and an upper fixing seat 2414. The control handle 2411 is located at the upper end of the adjusting stud 2412. One end of the control shaft 2413 is threadedly connected to the adjusting stud 2412, and the other end is fixedly mounted on the multi-bar device 242. The specific working principle is that by rotating the adjusting stud 2412 with the control handle 2411, the control shaft 2413 moves up and down on the adjusting stud 2412, thereby driving the extension and retraction of the multi-bar device 242. Specifically, the control shaft 2413 is mounted on the hinge shaft of any one of the first and second connecting rods in the multi-bar device 242. The control handle 2411 includes a handle and a control linkage. The handle is mounted on one end of the control linkage via a bearing, and the other end of the control linkage is connected to the adjusting stud 2412. The handle is located on the side away from the adjusting stud 2412, and the extension direction of the handle is parallel to the extension direction of the adjusting stud 2412 to facilitate manual control.

[0083] Since the multi-bar device 242 is located inside the pressing plate 23, a second guide groove 233 is provided on the pressing plate 23 to facilitate the connection between the control shaft 2413 and the multi-bar device 242. The control shaft 2413 passes through the second guide groove 233 and connects to the telescopic connecting rod 2422a of the multi-bar device 242.

[0084] See attached document Figure 17 and Figure 18 As shown, the pressure roller mechanism 25 includes a positioning handle 251, a guide shaft 254, and a pressure roller unit 252. The guide shaft 254 is disposed in the first guide groove 232. The positioning handle 251 and the pressure roller unit 252 are respectively disposed at both ends of the guide shaft 254. The positioning handle 251 is located on the outside of the pressing plate 23, and the pressure roller unit 252 is located on the inside of the pressing plate 23. An elastic device is provided on the guide shaft 254 between the pressure roller unit 252 and the pressing plate 23. The preferred elastic device is a rectangular spring 253. The rectangular spring 253 can elastically press the edge silicon material, and the silicon block will not be damaged due to the hard pressure of the pressure roller unit 252.

[0085] The positioning handle 251 includes a pull rod 2511 and a positioning block 2512. Limiting strips 234 are respectively provided on both sides of the pressing plate 23 corresponding to the first guide groove 232. The positioning block 2512 is located between the two limiting strips 234, which can prevent the pressure roller mechanism 25 from rotating relative to the edge silicon material during operation and improve the stability of pressing. The length of the pull rod 2511 is greater than the distance between the two limiting strips 234, which facilitates operation by the user.

[0086] See attached document Figure 18 As shown, the bottom surface of the positioning block 2512 is provided with a bottom hole 2512a for the guide shaft 254 to pass through. At least one side of the positioning block 2512 is provided with a threaded hole 2512b, preferably two threaded holes 2512b, respectively located on opposite sides of the positioning block 2512. Fixing bolts are respectively installed in the threaded holes 2512b. A fixing groove 2541 is provided at the end of the guide shaft 254 connected to the positioning block 2512. The fixing groove 2541 matches the fixing bolt, thereby fixing the guide shaft 254 on the positioning block 2512. Furthermore, a locking nut 255 is provided on the guide shaft 254 between the positioning block 2512 and the pressing plate 23. The locking nut 255 is threadedly connected to the guide shaft 254, facilitating the fixing of the guide shaft 254 and ensuring a stable connection between it and the positioning block 2512.

[0087] The pressure roller unit 252 includes a pressure roller bracket 2521 and at least one pressure roller. Preferably, there are two pressure rollers, and the two pressure rollers are located on the same horizontal line to ensure balanced force on the edge silicon material, allowing it to press firmly against the corresponding positioning plate under pressure. All the pressure rollers are fixedly mounted at the end of the pressure roller bracket 2521 away from the guide shaft 254, and the pressure rollers are rubber-coated bearings 2522, which can buffer the pressure between the pressure roller and the edge silicon material. To increase the stability of the fixation between the guide shaft 254 and the pressure roller bracket 2521, a long-direction limiting groove 2523 is provided in the middle of the pressure roller bracket 2521, and a cuboid mounting structure corresponding to the limiting groove 2523 is provided at one end of the guide shaft 254. With the screw connection structure between the guide shaft 254 and the limiting groove 2523, the two are firmly connected, and relative rotation between the guide shaft 254 and the pressure roller bracket 2521 can be avoided. The screw connection method can also be a snap-fit ​​connection or a tenon connection.

[0088] like Figure 5 As shown, the pressing component of the edge silicon material bonding device also includes a top pressing component 3, which is fixed on the positioning device and used to press from the top after the edge silicon material is bonded, so as to cure the bonded silicon rod.

[0089] Combined with appendix Figure 19 As shown, the top clamping assembly 3 includes a support base 36, a pressure bearing plate 37, and a linear motion module. The linear motion module is vertically movable and mounted on the support base 36. The support base 36 is an L-shaped welded piece made of two steel plates and is fixed to the base assembly 1 by bolts. The pressure bearing plate 37 is fixedly mounted at the bottom end of the linear motion module. During clamping, the pressure bearing plate 37 directly contacts the uppermost edge silicon material and applies pressure to the bonded edge silicon rod under the action of the linear motion module. Specifically, the linear motion module includes a guide unit and a motion unit. The motion unit is mounted on the guide unit to control the movement of the guide unit in a fixed direction, and the pressure bearing plate 37 is fixed at the bottom end of the guide unit.

[0090] Reference Figure 19As shown, the guide unit includes a floating support plate 32 and at least one support rod 34, preferably two support rods 34. The two support rods 34, the floating support plate 32, and the pressure bearing plate 37 together form a rectangular guide support frame. All the support rods 34 are arranged parallel to each other between the floating support plate 32 and the pressure bearing plate 37, and the support rods 34 are slidably mounted on the support seat 36 through bushings 35. That is, there is no specific connection between the support rods 34 and the support seat 36. The support seat 36 only limits the support rods 34 to ensure their movement in the vertical direction.

[0091] The motion unit includes a power handle 31 and a motion screw 33. The power handle 31 is connected to the motion screw 33 to control the rotation of the motion screw 33. The upper part of the motion screw 33 is connected to the floating support plate 32 via a bearing, and the motion screw 33 is connected to a screw nut fixed on the support base 36. The bottom of the motion screw 33 can be connected to the pressure bearing plate 37 via a mounting base. Preferably, the threads on the motion screw 33 and the screw nut are trapezoidal threads. Since the helix angle of the trapezoidal thread is less than the static friction force, it has a certain self-locking performance, so that the top pressing assembly 3 will not fall under the action of gravity when it is raised to the highest position.

[0092] The edge silicon material bonding device designed in this invention is manually operated. The first edge silicon material is placed on the second silicon material contact plate 14 of the base assembly 1, with its rear and right sides in contact with the first silicon material contact plate 13. A layer of adhesive is applied to the top surface of the edge silicon material. The second edge silicon material is then placed on the adhesive-coated surface of the first edge silicon material. Subsequent silicon materials are bonded in the same manner. No adhesive is needed on the surfaces of the first and second silicon material contact plates 14, or on the surface of the last edge silicon material in contact with the top pressing assembly 3. After all the edge silicon materials are stacked, they are pressed together in the length and width directions using the length pressing assembly 22 and width pressing assembly 21, respectively. Locking clamps are used to hold the two side pressing assemblies 2 in place. Finally, the thickness direction of the edge silicon material is pressed together using the top pressing assembly 3. After pressing, the adhesive is allowed to cure for a certain period to complete the bonding process.
