Description

Technical Field

[0001] This utility model relates to the field of solar cell manufacturing technology, specifically a device for improving crystal desiccation caused by wear of the support teeth. Background Technology

[0002] In the production of solar cells, the support teeth are key components that support the silicon wafers. They are usually plastic or metal components with toothed protrusions. The densely arranged toothed structure fixes the position of the solar cells and prevents them from shifting during welding or transportation.

[0003] In the production process, the support teeth drive the solar cells to move between different production stations. For example, on an automated production line for solar cells, the support teeth move with the conveyor belt. During this movement, the support teeth need to maintain a stable speed and positional accuracy to ensure that the silicon wafers can accurately reach each station and meet the requirements of the production process.

[0004] However, during operation, mechanical wear, residual solar cell fragments, and uneven stress can all cause local support failure of the support teeth, ultimately leading to the solar cells falling off or being damaged (i.e., "de-crystallization").

[0005] Therefore, a device is proposed to address the above-mentioned problem by improving the decrystallization caused by wear of the support teeth. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The device for improving the decrystallization caused by wear of the support tooth, as described in this utility model, includes a support beam; the support beam is fixedly connected to the bottom side of the support tooth; a winch mechanism is fixedly connected to the bottom of both ends of the support beam; a wear-resistant belt is provided between the two winch mechanisms; the wear-resistant belt passes over the top surface of the support beam; the winch mechanism includes a housing fixedly connected to the bottom surface of the end of the support beam; a winding wheel is rotatably installed inside the housing; the two ends of the wear-resistant belt are respectively wound around the outer ring of the two winding wheels.

[0008] Preferably, a support rod is rotatably mounted inside the housing on the side near the end of the support beam; the winding wheel is fixedly connected to the outer ring of the support rod; a driven gear is fixedly connected to the outer ring of the support rod near the tooth; a drive rod is rotatably mounted inside the housing on the side near the middle of the support beam; a drive gear is fixedly connected to the outer ring of the drive rod; and the drive gear meshes with the driven gear.

[0009] Preferably, the outer ring of the drive rod is fixedly connected with a plurality of protruding strips; the outer ring of the drive rod is provided with a limiting cylinder; one end of the limiting cylinder is fixedly connected to the inner wall of the housing; the inner ring of the limiting cylinder is fixedly connected with a plurality of elastic strips; the elastic strips and the protruding strips can be squeezed and slidably engaged.

[0010] Preferably, the winding wheel has slots on both sides; a pressure strip is bolted between the slots on both sides; the pressure strip can press and fix the end of the wear-resistant belt.

[0011] Preferably, a support beam is bolted to the top of the side of the housing near the end of the support beam; rollers are installed on both sides of the end of the support beam away from the housing; the rollers slide in contact with the outer wall of the wear-resistant belt; and a convex ring is fixedly connected to the outer ring of the side of the roller away from the support beam.

[0012] Preferably, both ends of the support beam are bolted with vertical walls; a pressure plate that can be pressed down is slidably installed on the top of the side of the vertical wall near the support beam.

[0013] The advantages of this utility model are: 1. The device for improving the desiccation caused by wear of the support teeth according to this utility model is configured with a support beam, a wear-resistant belt, a housing, and a winding wheel. The edge of the solar cell contacts the wear-resistant belt on the top surface of the support beam, avoiding contact between the edge of the solar cell and the bottom of the tooth groove, thereby reducing the wear of the support teeth. When the surface of the wear-resistant belt is worn by the edge of the solar cell, the winding wheel on one side is rotated to wind the worn wear-resistant belt on the top surface of the support beam onto the winding wheel. At the same time, the winding wheel on the other side is driven to rotate by the wear-resistant belt, moving the outer ring of the new wear-resistant belt to the top surface of the support beam. This reduces the maintenance time of the support teeth and effectively reduces the occurrence of solar cell detachment or damage.

[0014] 2. The device for improving the desiccation caused by wear of the support teeth described in this utility model is provided with a vertical wall and a pressure plate. The vertical wall and the pressure plate effectively prevent the wear-resistant belt on the top surface of the support beam from detaching during movement. After the wear-resistant belt on the top surface of the support beam is moved and replaced, the pressure plate presses down on the wear-resistant belt on the top surface of the support beam, pressing the wear-resistant belt tightly against the top surface of the support beam, thereby preventing the wear-resistant belt from moving when placing and removing solar cells.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] like Figures 1 to 4As shown, a device for improving desiccation caused by wear of the support teeth includes a support beam 1; the support beam 1 is fixed to the bottom side of the support teeth; a winch mechanism is fixed to the bottom of both ends of the support beam 1; a wear-resistant belt 2 is arranged between the two winch mechanisms; the wear-resistant belt 2 passes over the top surface of the support beam 1; the winch mechanism includes a housing 3 fixed to the bottom surface of the end of the support beam 1; a winding wheel 4 is rotatably installed inside the housing 3; the two ends of the wear-resistant belt 2 are respectively wound around the outer ring of the two winding wheels 4. Specifically, the bottom of the support tooth is a long strip-shaped support plate, and multiple teeth are evenly fixed to the top surface of the support plate. The teeth have a sword-point-shaped structure, and the thickness of the solar cell is matched between two adjacent teeth. The bottom of the support beam 1 has a groove on the side away from the support tooth, and multiple straight slots are evenly provided inside the groove. Bolts are used to pass through the straight slots and fix it to the side of the support plate at the bottom of the support tooth. The length of the support beam 1 matches the length of the support tooth. Both ends of the support beam 1 are provided with rounded corners. Hangers 5 are fixed to the bottom surfaces of both ends of the support beam 1. The top of the hanger 5 is a hanger rod, and a flange is fixed to the outer ring of the top of the hanger rod. The flange is fixed to the bottom surfaces of both ends of the support beam 1 by multiple screws. The bottom of the hanger 5 is an inverted U-shaped seat, and a through hole is opened in the middle of the inverted U-shaped seat. The top surface of the housing 3 is fixedly connected to a protruding plate that matches the inverted U-shaped seat at the bottom of the hanger 5, and the protruding plate is fixedly installed in the middle of the inverted U-shaped seat by bolts through the through hole of the inverted U-shaped seat, so that the housing 3 is fixedly locked to the bottom of the hanger 5. The side of the housing 3 away from the support tooth is open and is fixed with a cover plate by bolts; a through groove is opened on the side of the housing 3 away from the middle of the support beam 1, the winding wheel 4 is rotatably installed inside the housing 3, and the wear-resistant belt 2 passes through the through groove on the side of the housing 3. In use, fix the two ends of the wear-resistant belt 2 onto the two winding wheels 4, install the two winding wheels 4 into the housing 3 at both ends of the support beam 1 respectively, and place the wear-resistant belt 2 into the through groove on the side of the housing 3; wrap the wear-resistant belt 2 around the top surface of the support beam 1 from both ends; fix and lock one winding wheel 4, and rotate the other winding wheel 4 to tighten the wear-resistant belt 2 so that the wear-resistant belt 2 is in close contact with the top surface of the support beam 1; When the solar cell is placed between the teeth of the support tooth, the edge of the solar cell contacts the wear-resistant belt 2 on the top surface of the support beam 1, which avoids the edge of the solar cell contacting the bottom of the tooth groove, thereby reducing the wear of the support tooth. When the surface of the wear-resistant belt 2 is worn by the edge of the solar cell, the winding wheels 4 inside the two side housings 3 are loosened, and one winding wheel 4 is rotated to wind the worn wear-resistant belt 2 on the top surface of the support beam 1 onto the winding wheel 4. At the same time, the other winding wheel 4 is rotated by the wear-resistant belt 2, moving the new wear-resistant belt 2 around the outer ring of the winding wheel 4 to the top surface of the support beam 1. Then, the winding wheels 4 are fixed again. This reduces the maintenance time of the support teeth and effectively reduces the occurrence of solar cell detachment or damage.

[0020] Furthermore, such as Figures 2 to 4 As shown, a support rod 6 is rotatably mounted inside the housing 3 near the end of the support beam 1; the winding wheel 4 is fixedly connected to the outer ring of the support rod 6; a driven gear 7 is fixedly connected to the outer ring of the support rod 6 near the tooth; a drive rod 8 is rotatably mounted inside the housing 3 near the middle of the support beam 1; a drive gear 9 is fixedly connected to the outer ring of the drive rod 8; the drive gear 9 meshes with the driven gear 7. Specifically, the housing 3 has an elliptical structure, and the diameter of one end of the housing 3 located at the winding wheel 4 is larger than the diameter of the other end; the diameter of the drive gear 9 is smaller than the diameter of the driven gear 7; one end of the drive rod 8 rotates through the cover plate of the housing 3, and a rotating cap is fixed to the end of the drive rod 8. In use, rotating the drive rod 8 drives the drive gear 9 to rotate. Since the drive gear 9 meshes with the driven gear 7, the drive gear 9 drives the driven gear 7 to rotate, which in turn drives the support rod 6 to rotate, and then drives the winding wheel 4 to rotate, thereby realizing the winding and unwinding of the wear-resistant belt 2. Furthermore, since the diameter of the drive gear 9 is smaller than that of the driven gear 7, the drive gear 9 drives the driven gear 7 in a force-saving manner, thereby reducing the force required to wind up the wear-resistant belt 2, which in turn helps to straighten and tighten the wear-resistant belt 2 on the top surface of the support beam 1.

[0021] In some embodiments, such as Figures 3 to 5 As shown, the outer ring of the drive rod 8 is fixedly connected with a plurality of protruding strips 10; the outer ring of the drive rod 8 is provided with a limiting cylinder 11; one end of the limiting cylinder 11 is fixedly connected to the inner wall of the housing 3; the inner ring of the limiting cylinder 11 is fixedly connected with a plurality of elastic strips 12; the elastic strips 12 and the protruding strips 10 can be squeezed and slidably engaged. Specifically, the protruding strip 10 is a semi-circular strip structure, and multiple protruding strips 10 are fixedly connected to the outer ring of the drive rod 8; the limiting cylinder 11 is fixedly connected to the cover plate of the housing 3 by screws, and the elastic strip 12 has a semi-circular ring cross section; after the elastic strip 12 is squeezed by the protruding strip 10, the elastic strip 12 will be compressed towards the inner wall of the limiting cylinder 11, so that the protruding strip 10 slides over the elastic strip 12; When in use, when the drive rod 8 is rotated, the protrusion 10 on the outer ring of the drive rod 8 rotates, causing the protrusion 10 to squeeze the elastic strip 12 on the inner ring of the limiting cylinder 11, causing the elastic strip 12 to be compressed. The protrusion 10 can slide over the compressed elastic strip 12, thereby driving the winding wheel 4 to rotate. When the drive rod 8 stops rotating, the protrusion 10 on the outer ring of the drive rod 8 gets stuck between two adjacent elastic strips 12. The elastic strips 12 block the protrusion 10 on the outer ring of the drive rod 8, thereby effectively blocking the rotation of the drive rod 8 and locking the winding wheel 4 in place. This prevents the winding wheel 4 from rotating accidentally and causing the wear-resistant belt 2 on the top surface of the support beam 1 to loosen.

[0022] In some embodiments, such as Figures 3 to 6 As shown, the winding wheel 4 has slots 13 on both sides; a pressure strip 14 is bolted between the slots 13 on both sides; the pressure strip 14 can press and fix the end of the wear-resistant belt 2. Specifically, the winding wheel 4 has a cylindrical center, with circular plates fixed to both ends. Slots 13 are formed on the circular plates on both sides of the winding wheel 4, with corresponding slots on both sides. Screw holes are formed at the bottom of the slots 13, and countersunk holes corresponding to the screw holes are formed at both ends of the pressure strip 14. The pressure strip 14 is fixedly installed between the slots 13 on both sides by a countersunk screw passing through the countersunk hole of the pressure strip 14 and engaging with the screw hole of the slot 13. The pressure strip 14 engages with the outer wall of the winding wheel 4 in the middle, clamping and locking the end of the wear-resistant belt 2, thereby locking the end of the wear-resistant belt 2 to the winding wheel 4, facilitating the winding of the wear-resistant belt 2 onto the outer ring of the winding wheel 4.

[0023] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a support beam 15 is bolted to the top of the side of the housing 3 near the end of the support beam 1; rollers 16 are installed on both sides of the end of the support beam 15 away from the housing 3; the rollers 16 slide in contact with the outer wall of the wear-resistant belt 2; a convex ring 17 is fixedly connected to the outer ring of the side of the rollers 16 away from the support beam 15. Specifically, a block is fixed to the top of the side of the housing 3 near the end of the support beam 1, and a screw is fixed to one end of the block. A through hole is opened at one end of the support beam 15, and the screw slides through the through hole at the end of the support beam 15. A locking nut is threaded on the outer ring of the screw. The locking nut and the screw work together to compress the support beam 15. With the blocking of the block, the support beam 15 is locked and fixed. At the same time, the orientation of the support beam 15 can be adjusted. A rotating shaft is rotatably installed at the middle of the end of the support beam 15 away from the housing 3. Two rollers 16 are respectively rotatably installed on the outer rings of the two ends of the rotating shaft. In use, after the wear-resistant belt 2 passes over the top surface of the support beam 1, loosen the locking nut at the end of the support beam 15, push the support beam 15 to rotate around the screw, so that the roller 16 presses against the wear-resistant belt 2, making the wear-resistant belt 2 taut, and the convex rings 17 on both sides block the two sides of the wear-resistant belt 2, preventing the wear-resistant belt 2 from falling off. Then tighten the locking nut to lock and fix the support beam 15. This not only improves the tautness of the wear-resistant belt 2, but also reduces the possibility of the wear-resistant belt 2 falling off the top surface of the support beam 1.

[0024] In some embodiments, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, both ends of the support beam 1 are bolted with vertical walls 18; a pressure plate 19 that can be pressed down is slidably installed on the top of the side of the vertical wall 18 near the support beam 1. Specifically, multiple threaded holes are provided at both ends of both sides of the support beam 1, and the multiple threaded holes are arranged around the beam. A positioning square hole is provided in the middle of the multiple threaded holes. Multiple stepped holes are provided around the bottom of the vertical wall 18, and multiple screws pass through the stepped holes and engage with the threaded holes to fix and lock the vertical wall 18 to the support beam 1. A positioning block that matches the positioning square hole is fixed to the bottom of the vertical wall 18 to facilitate accurate installation. The top of the vertical wall 18 is evenly provided with three vertically arranged sliding grooves 20. A top plate is bolted to the top surface of the vertical wall 18. Guide rods 21 are fixedly connected inside the sliding grooves 20 on both sides. A lead screw 22 is rotatably installed inside the sliding groove 20 in the middle, and the top end of the lead screw 22 rotatably passes through the top plate. Three protrusions are fixedly connected to the side of the pressure plate 19 near the vertical wall 18. The protrusions slide with the sliding grooves 20. The guide rods 21 on both sides slide through the protrusions on both sides. The lead screw 22 is threaded with the protrusion in the middle. The bottom of both sides of the pressure plate 19 is provided with arc-shaped chamfers. In use, when it is necessary to move the wear-resistant belt 2 on the top surface of the support beam 1, the screw 22 is rotated to drive the pressure plate 19 to slide upward along the slide groove 20. At the same time, since the guide rod 21 passes through the protrusion of the pressure plate 19, it prevents the pressure plate 19 from detaching from the vertical wall 18 and ensures that the pressure plate 19 is always in a horizontal state. After the pressure plate 19 rises to a certain height, it separates from the wear-resistant belt 2 on the top surface of the support beam 1. Through the obstruction of the vertical wall 18 and the pressure plate 19, the wear-resistant belt 2 on the top surface of the support beam 1 is effectively prevented from detaching when it moves. After the wear-resistant belt 2 on the top surface of the support beam 1 has been moved and replaced, the screw 22 is rotated in the opposite direction, causing the pressure plate 19 to slide down along the slide groove 20. This causes the pressure plate 19 to press down on the wear-resistant belt 2 on the top surface of the support beam 1, pressing the wear-resistant belt 2 tightly against the top surface of the support beam 1. This prevents the wear-resistant belt 2 from moving when placing and removing solar cells.

[0025] Working principle: The two ends of the wear-resistant belt 2 are fixed to the two winding wheels 4. The countersunk screws pass through the countersunk holes of the pressure strip 14 and engage with the screw holes of the slot 13 to fix the pressure strip 14 between the slots 13 on both sides. The pressure strip 14 engages with the middle outer wall of the winding wheel 4 to clamp and lock the end of the wear-resistant belt 2. The two winding wheels 4 are respectively installed inside the housing 3 at both ends of the support beam 1, and the wear-resistant belt 2 is placed in the through groove on the side of the housing 3. The wear-resistant belt 2 is wrapped around the top surface of the support beam 1 from both ends. Loosen the locking nut at the end of the support beam 15 and push the support beam 15 to rotate around the screw, so that the roller 16 presses against the wear-resistant belt 2, making the wear-resistant belt 2 taut, and the convex rings 17 on both sides block the two sides of the wear-resistant belt 2 to prevent the wear-resistant belt 2 from falling off. Then tighten the locking nut to lock and fix the support beam 15. Rotate the screw 22 in the opposite direction to drive the pressure plate 19 to slide down along the slide groove 20, so that the pressure plate 19 presses down on the wear-resistant belt 2 on the top surface of the support beam 1, pressing the wear-resistant belt 2 tightly on the top surface of the support beam 1. When the solar cell is placed between the teeth of the support tooth, the edge of the solar cell contacts the wear-resistant belt 2 on the top surface of the support beam 1, which avoids the edge of the solar cell contacting the bottom of the tooth groove, thereby reducing the wear of the support tooth. When the surface of the wear-resistant belt 2 is worn by the edge of the solar cell, the screw 22 is rotated, causing the pressure plate 19 to slide upward along the groove 20. At the same time, since the guide rod 21 passes through the protrusion of the pressure plate 19, it prevents the pressure plate 19 from detaching from the vertical wall 18 and ensures that the pressure plate 19 is always in a horizontal state. After the pressure plate 19 rises to a certain height, it separates from the wear-resistant belt 2 on the top surface of the support beam 1. Rotating one side of the drive rod 8 drives the drive gear 9 to rotate. Since the drive gear 9 meshes with the driven gear 7, the drive gear 9 drives the driven gear 7 to rotate, which in turn drives the support rod 6 to rotate, and then drives the winding wheel 4 to rotate. The wear-resistant belt 2 worn on the top surface of the support beam 1 is wound onto the winding wheel 4. At the same time, the winding wheel 4 on the other side is driven to rotate by the wear-resistant belt 2, moving the new wear-resistant belt 2 around the outer ring of the winding wheel 4 to the top surface of the support beam 1. Then, the winding wheels 4 are fixed after both rotations. This reduces the maintenance time of the support teeth and effectively reduces the occurrence of solar cell detachment or damage.
