Description

Technical Field

[0001] This utility model belongs to the technical field of welding strip processing equipment, specifically relating to a wear-resistant structure for copper wire feeding in welding strip processing. Background Technology

[0002] Solder strip, also known as tin-plated copper strip or tin-coated copper strip, is divided into busbars and interconnect strips. It is used to connect the cells of photovoltaic modules, playing an important role in conducting and concentrating electricity. During the processing of solder strip, copper wires are fed into solder strip processing equipment for quenching, fluxing, and tin plating. During the feeding of copper wires, it is necessary to guide and feed the copper wires to ensure their orderly movement.

[0003] Most existing welding strip guiding structures use rings for guidance. Since the inner side of the ring is bent and the ring and the equipment are connected in a fixed manner, the ring will scrape the moving copper wire during the copper wire feeding process, thereby abrading the surface of the copper wire. This not only causes material loss, but may also reduce the qualification rate of the welding strip, greatly reducing its practicality. Summary of the Invention

[0004] This utility model provides a wear-resistant structure for copper wire feeding in welding strip processing. Its purpose is to solve the problem that most existing welding strip guiding structures use rings for guidance. Since the inner side of the ring is bent and the ring and the equipment are connected in a fixed way, the ring will scrape the moving copper wire during the copper wire feeding process, thus wearing down the surface of the copper wire. This not only causes material loss, but may also reduce the qualification rate of the welding strip and greatly reduce its practicality.

[0005] This utility model embodiment provides a wear-resistant structure for copper wire feeding in welding strip processing, including a welding strip processing equipment. A feeding trough is provided on one side of the welding strip processing equipment. A guide wheel is provided inside the feeding trough. Two bases are symmetrically fixedly connected to the upper end of the feeding trough. A roller is installed on the front side between the two bases. The two ends of the roller are rotatably connected to the bases through bearings. A roller is installed on the rear side between the two bases. A mounting plate is fixedly connected to one side of the base. A motor is fixedly connected to the upper end of the mounting plate. The output end of the motor is connected to one end of the adjacent roller.

[0006] By adopting the above technical solution, the rotation direction of the first roller is consistent with the movement direction of the copper wire. At the same time, the first roller is cylindrical, which greatly reduces the friction between the first roller and the copper wire, avoids wear caused by scratching during the feeding process of the copper wire, ensures the qualification rate of the welding strip processing, and greatly improves the practicality of the equipment. Furthermore, the second roller can limit the movement of the copper wire, prevent the copper wire from jumping out of the first roller during the movement, and ensure the normal movement and processing of the copper wire.

[0007] Furthermore, a sealing ring is provided between the two sides of the base and the end of the first roller.

[0008] By adopting the above technical solution and setting the sealing ring, the sealing between the roller and the base is ensured, thereby preventing oil leakage.

[0009] Furthermore, a maintenance structure is provided on the base.

[0010] By adopting the above technical solution and setting up the maintenance structure, the bearing installed between the roller and the base is lubricated, ensuring the smoothness of the bearing.

[0011] Furthermore, the maintenance structure includes an oil injection assembly, which includes an oil storage chamber and a flow hole opened on the outer ring of the bearing. The oil storage chamber and the flow hole are connected through an oil injection port. The oil injection assembly also includes a sealing ball tightly attached to the oil injection port. A connecting rod is fixedly connected to the upper end of the sealing ball. An L-shaped plate is fixedly connected to the upper end of the connecting rod through the oil storage chamber. A spring is sleeved on the outer side of the connecting rod. The two ends of the spring are respectively fixedly connected to the upper end of the base and the inner wall of the L-shaped plate. A slide rail is slidably connected to the outer side of the L-shaped plate. The lower end of the slide rail is fixedly connected to the upper wall of the base.

[0012] By adopting the above technical solution, during oil injection, the L-shaped plate moves upward, the spring extends, the connecting rod moves upward with the L-shaped plate, and the connecting rod moves upward with the sealing ball, thereby opening the oil injection port and connecting the oil reservoir to the flow hole. This allows the oil in the oil reservoir to be injected into the bearing for lubrication, thus achieving the maintenance effect of the bearing. After oil injection is completed, under the tension of the spring, the L-shaped plate is driven downward, the L-shaped plate moves downward with the connecting rod, and the connecting rod moves downward with the sealing ball. This seals the oil injection port stably, preventing excessive oil from flowing into the bearing, thereby achieving quantitative oil injection.

[0013] Furthermore, the maintenance structure also includes a drive assembly, which includes a cam fixedly connected to one end of the roller and a push block fixedly connected to the outside of the L-shaped plate. The cam can rotate with the roller, and the push block is located on the rotation trajectory of the sharp part of the cam.

[0014] By adopting the above technical solution, the rotation of the drum drives the cam to rotate. When the cam rotates to contact the push block, the cam squeezes the push block. When the cam continues to move, it causes the push block to move upward, thereby driving the oil injection component to open for oil injection. When the cam leaves the push block, the oil injection component resets and seals, thereby driving the oil injection component to intermittently inject oil for maintenance.

[0015] Furthermore, the push block has a wedge-shaped structure.

[0016] By adopting the above technical solution, the wedge structure facilitates the upward movement of the cam-driven block.

[0017] Furthermore, a gap is left between the guard plates on both sides of the first roller and the guard plates on both sides of the second roller.

[0018] By adopting the above technical solution, gaps are left between the guard plates, which can prevent the second roller from affecting the first roller when the first roller is rolling.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model, through the setting of roller one, the rotation direction of roller one is consistent with the movement direction of copper wire. At the same time, roller one is cylindrical, which greatly reduces the friction between roller one and copper wire, avoids wear caused by scratching of copper wire during feeding, ensures the qualification rate of welding strip processing, and greatly improves the practicality of equipment. Furthermore, through the setting of roller two, the moving copper wire can be limited to prevent the copper wire from jumping out of roller one during movement, ensuring the normal movement and processing of copper wire.

[0021] 2. During oil injection, the L-shaped plate moves upward, the spring extends, and the connecting rod moves upward along with the L-shaped plate. The connecting rod, along with the sealing ball, moves upward, thereby opening the oil injection port and connecting the oil storage chamber with the flow hole. This allows the oil in the oil storage chamber to be injected into the bearing for lubrication, thus achieving the maintenance effect on the bearing. After oil injection is completed, the L-shaped plate moves downward under the tension of the spring. The L-shaped plate moves downward, and the connecting rod moves downward, causing the sealing ball to move downward. The sealing ball then stably blocks the oil injection port, preventing excessive oil from flowing into the bearing, thereby achieving quantitative oil injection.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Reference Figures 1-4This utility model embodiment proposes a wear-resistant structure for copper wire feeding in welding strip processing, including a welding strip processing equipment 8. A feeding trough 1 is provided on one side of the welding strip processing equipment 8. A guide wheel 7 is installed inside the feeding trough 1. Two bases 2 are symmetrically fixedly connected to the upper end of the feeding trough 1. A roller 5 is installed on the front side between the two bases 2. The two ends of the roller 5 are rotatably connected to the bases 2 via bearings 3. A roller 6 is installed on the rear side between the two bases 2. The rotation direction of the roller 5 is consistent with the movement direction of the copper wire. Simultaneously, the roller 5 is cylindrical, which greatly reduces the friction between the roller 5 and the copper wire, avoiding wear caused by scraping during the feeding process, ensuring the qualification rate of welding strip processing, and greatly improving the practicality of the equipment. Furthermore, the roller 6 can limit the movement of the copper wire, preventing it from jumping out of the roller 5 during movement, ensuring normal movement and processing of the copper wire.

[0034] Reference Figure 2 and Figure 6 A sealing ring 301 is provided between the two sides of the base 2 and the end of the roller 5. The sealing ring 301 ensures the sealing between the roller 5 and the base 2, thereby preventing oil leakage.

[0035] Reference Figures 1-7 The base 2 is equipped with a maintenance structure 4, which lubricates the bearing 3 installed between the roller 5 and the base 2, ensuring the smooth operation of the bearing 3.

[0036] Reference Figures 1-7The maintenance structure 4 includes an oil injection assembly 41, which includes an oil storage chamber 411 and a flow hole 302 opened on the outer ring of the bearing 3. The oil storage chamber 411 and the flow hole 302 are connected through an oil injection port 412. The oil injection assembly 41 also includes a sealing ball 413 tightly attached to the oil injection port 412. A connecting rod 414 is fixedly connected to the upper end of the sealing ball 413. An L-shaped plate 415 is fixedly connected to the upper end of the connecting rod 414 through the oil storage chamber 411. A spring 416 is sleeved on the outside of the connecting rod 414. The two ends of the spring 416 are respectively fixedly connected to the upper end of the base 2 and the inner wall of the L-shaped plate 415. A slide rail 423 is slidably connected to the outside of the L-shaped plate 415. The lower end of the slide rail 423 is fixedly connected to the upper wall of the base 2. When oil is applied, the L-shaped plate 415 moves upward, the spring 416 extends, and the connecting rod 414 moves upward along with the L-shaped plate 415. The connecting rod 414 moves upward with the sealing ball 413, thereby opening the oil inlet 412 and connecting the oil reservoir 411 with the flow hole 302. This allows the oil in the oil reservoir 411 to be injected into the bearing 3 for lubrication, thus achieving the maintenance effect of the bearing 3. After the oil is injected, the L-shaped plate 415 moves downward under the tension of the spring 416. The L-shaped plate 415 drives the connecting rod 414 to move downward, and the connecting rod 414 drives the sealing ball 413 to move downward. The sealing ball 413 then stably blocks the oil inlet 412, preventing excessive oil from flowing into the bearing 3, thereby achieving quantitative oil injection.

[0037] Reference Figures 1-7 The maintenance structure 4 also includes a drive assembly 42, which includes a cam 421 fixedly connected to the end of the roller 5 and a push block 422 fixedly connected to the outside of the L-shaped plate 415. The cam 421 can rotate with the roller 5, and the push block 422 is on the rotation trajectory of the sharp part of the cam 421. The rotation of the roller 5 drives the cam 421 to rotate. When the cam 421 rotates to contact the push block 422, the cam 421 squeezes the push block 422. When the cam 421 continues to move, it causes the push block 422 to move upward, thereby driving the oil injection assembly 41 to open for oil injection. When the cam 421 leaves the push block 422, the oil injection assembly 41 resets and seals, thereby driving the oil injection assembly 41 to intermittently inject oil for maintenance.

[0038] Reference Figure 7 The push block 422 has a wedge-shaped structure, which facilitates the upward movement of the push block 422 by the cam 421.

[0039] Reference Figures 1-4 There is a gap between the guard plates on both sides of roller 5 and roller 6. The gap between the guard plates can prevent roller 6 from affecting roller 5 when roller 5 is rolling.

[0040] Reference Figures 1-3A mounting plate is fixedly connected to one side of the base 2, and a motor 9 is fixedly connected to the upper end of the mounting plate. The output end of the motor 9 is connected to one end of the adjacent roller 5. The motor 9 drives the roller 5 to rotate, so that the cam 421 on the roller 5 can smoothly squeeze and push the block 422 to move. At the same time, the roller 5 and the copper wire can maintain the same speed in the same direction, thereby further reducing the friction between the roller 5 and the copper wire, avoiding wear caused by scratching of the copper wire during the feeding process, ensuring the qualification rate of the welding strip processing, and greatly improving the practicality of the equipment.

[0041] The specific implementation method is as follows: When the copper wire is fed, it is threaded between roller 5 and roller 6, and then passes around the guide wheel 7 into the welding strip processing equipment 8. The operation of the motor 9 drives roller 5 to rotate. Roller 5 and the copper wire move synchronously, reducing the friction between the copper wire and the surface of roller 5 during movement. This avoids wear caused by scratching during the feeding process, ensuring the qualification rate of welding strip processing and greatly improving the practicality of the equipment. At the same time, the rotation of roller 5 will drive the cam 421 on roller 5 to rotate. When the cam 421 rotates to contact the push block 422, since the push block 422 is on the rotation trajectory of the sharp part of the cam 421, the cam 421 squeezes the push block 422. When the cam 421 continues to move, it causes the push block 422 to move upward, thereby driving the oil injection component 41 to open. During oil injection, the push block 422 moves the L-shaped plate 415 upward, the spring 416 extends, and the connecting rod 414 moves upward with the L-shaped plate 415. The connecting rod 414 moves upward with the sealing ball 413, thereby opening the oil injection port 412 and connecting the oil storage chamber 411 with the flow hole 302, thus injecting the oil in the oil storage chamber 411 into the bearing 3. After the oil injection is completed, the cam 421 continues to rotate, causing the cam 421 to leave the push block 422. Under the tension of the spring 416, the L-shaped plate 415 moves downward, which in turn moves the connecting rod 414 downward. The connecting rod 414 moves the sealing ball 413 downward, thus stably blocking the oil injection port 412 through the sealing ball 413, thereby preventing excessive oil from flowing into the bearing 3. This achieves quantitative oil injection, thereby completing the lubrication of the bearing 3 and ensuring the smooth flow of the bearing 3.
