Description

Technical Field

[0001] This utility model relates to the field of welding strip processing technology, specifically an adjustable photovoltaic circular welding strip processing device. Background Technology

[0002] Photovoltaic solder ribbon, also known as tin-plated copper ribbon or tin-coated copper ribbon, is divided into busbars and interconnecting strips. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity and collecting current. During the series connection of cells, the solder ribbon must be firmly welded to avoid the occurrence of cold solder joints or false solder joints. The quality of the solder ribbon will directly affect the current collection efficiency of the photovoltaic module and has a great impact on the power of the photovoltaic module.

[0003] However, existing welding ribbons are directly pulled into contact with the solar cells during welding. This means that if the welding ribbon has quality problems, the entire solar cell needs to be reprocessed. Designing a welding ribbon that is pre-processed to different lengths according to different needs can avoid this problem. An adjustable processing device can adapt to different solar panel spacing requirements, improving processing efficiency.

[0004] Therefore, it is necessary to design an adjustable photovoltaic circular welding strip processing device that is both practical and adaptable to different processing conditions. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable photovoltaic circular welding strip processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable photovoltaic circular welding strip processing device, comprising a base, a first support frame disposed above the base, a winding reel disposed above the first support frame, a central shaft disposed on the outer side of the first support frame, a first correction shaft disposed on the outer side of the first support frame, a second support frame disposed above the base, and a second correction shaft disposed above the second support frame.

[0007] According to the above technical solution, a processing table is provided above the base, an extension plate is provided on the outer side of the processing table, a slot plate is provided above the extension plate, a first roller is provided on the inner side of the processing table, a first cylinder is provided on the inner side of the processing table, a second roller is provided at the rod end of the first cylinder, a spring is welded to the outer shaft end of the second roller, the spring is welded to the first cylinder, a telescopic device is provided above the processing table, a cutting blade is provided at the sliding end of the telescopic device, and a second set of conveying components is provided above the processing table.

[0008] According to the above technical solution, a finished product plate is provided above the processing table, a push plate is slidably connected above the finished product plate, a first slide rail is provided above the base, a slider is slidably connected to the front end of the first slide rail, and a baffle is provided at the front end of the slider.

[0009] According to the above technical solution, a second slide rail is provided above the base, and a transfer compartment is provided at the sliding end of the second slide rail.

[0010] According to the above technical solution, a third slide rail is provided above the base, a shifting frame is slidably connected to the front end of the third slide rail, a second cylinder is provided at the front end of the shifting frame, a controller is provided at the rod end of the second cylinder, a gripping bracket is provided at the front end of the controller, a suction cup is provided at the bottom of the gripping bracket, and a conveyor belt is provided above the base.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) By providing a second set of conveying components, the second roller can slide up and down inside the processing table. When the welding strip is inserted into the gap, the second roller will rise, and then the welding strip will be subjected to downward pressure through the cooperation of the first cylinder and the spring. Then the first roller rotates, which can pull the welding strip inward. Due to the speed limitation of the take-up reel and the speed of the first roller being greater than that of the take-up reel, the welding strip will be in a taut state when pulled, thereby improving the processing quality. The second set of conveying components is the same as the front component but with a slightly higher rotation speed. Therefore, when the welding strip is conveyed into the second set of conveying components and pulled, the two conveying components are in a taut state. The section will be in a taut state, pulling the required length of welding strip according to the needs and letting it fall onto the finished board. Then, the cutting blade is controlled by the telescopic device to cut the welding strip, and the remaining welding strip is continued to be conveyed through the second set of conveying components to complete the cutting. The operation of the second set of conveying components realizes the pulling of the welding strip and can control the length of the pulled welding strip, so as to cut the welding strip into welding strips of different lengths. Afterwards, they can be inspected and collected in a unified manner for welding. Compared with the traditional operation of pulling and welding along with the solar panel, the quality of the welding strip can be detected in advance and the welding efficiency can be improved.

[0013] (2) A suction cup is provided and a conveyor belt is provided above the base. The second cylinder can drive the controller to descend through the air rod. At this time, the grabbing bracket falls close to the welding strip in the transfer chamber. By controlling the suction cup at the bottom of the grabbing bracket to suck air, the welding strip in the transfer chamber can be adsorbed. Then it rises and moves forward through the third slide rail to transfer the welding strip to the conveyor belt and put it down for transport. At this time, the worker can inspect each welding strip to observe whether it is damaged or does not meet the quality requirements. It is highly practical.

[0014] (3) A photovoltaic circular welding strip is wound on the take-up reel by setting a second correction shaft. The worker pulls it from the left side, through the right side of the central shaft, through the left side of the first correction shaft, and through the bottom of the second correction shaft. The take-up reel controls the speed of wire feeding by controlling the rotation speed of the motor. The welding strip will be corrected by the first correction shaft so that it can enter the subsequent processing device in the center position. The second correction shaft will correct it again to prevent deviation. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: an adjustable photovoltaic circular welding strip processing device, including a base 1, a first support frame 2 above the base 1, a take-up reel 3 above the first support frame 2, a central shaft 4 on the outer side of the first support frame 2, a first correction shaft 5 on the outer side of the first support frame 2, a second support frame 6 above the base 1, and a second correction shaft 7 above the second support frame 6. The photovoltaic circular welding strip is wound on the take-up reel 3. The worker pulls it from the left, passing through the right side of the central shaft 4, through the left side of the first correction shaft 5, and through the bottom of the second correction shaft 7. The take-up reel 3 controls the winding speed by controlling the rotation speed of the motor. The welding strip is corrected by the first correction shaft 5 so that it can enter the subsequent processing device in the center position. The second correction shaft 7 corrects it again to prevent deviation.

[0022] A processing table 8 is mounted above the base 1. An extension plate 9 is mounted on the outer side of the processing table 8, and a slot plate 10 is mounted above the extension plate 9. A first roller 11 and a first cylinder 12 are mounted on the inner side of the processing table 8. A second roller 14 is mounted on the rod end of the first cylinder 12, and a spring 13 is welded to the outer shaft end of the second roller 14. The spring 13 is welded to the first cylinder 12. A telescopic device 15 is mounted above the processing table 8, and a cutting blade 16 is mounted on the sliding end of the telescopic device 15. A second set of conveying components 17 is mounted above the processing table 8. The welding strip passes through the bottom of the slot plate 10 to prevent it from rotating or shifting, and then is inserted into the first roller 11 and the second roller 14. The second roller 14 can slide up and down inside the processing table 8. When the welding strip is inserted, the second roller 14 will rise, and then the first cylinder 12 and the spring 13 will work together to create downward pressure on the welding strip. Then the first roller 11 will rotate, pulling the welding strip inward. In the first conveyor assembly, due to the speed limitation of the take-up reel 3 and the higher rotation speed of the first roller 11 than the take-up reel 3, the welding strip will be in a taut state during the pulling process, thereby improving the processing quality. The second conveyor assembly 17 is the same as the first assembly but with a slightly higher rotation speed. Therefore, when the welding strip is conveyed into the second conveyor assembly 17 and pulled, the inside of both conveyor assemblies will be in a taut state. The required length of welding strip is pulled according to the needs and placed on the finished plate 18. Then, the cutting blade 16 is controlled by the telescopic device 15 to cut the welding strip. The remaining welding strip is then conveyed through the second conveyor assembly 17 to complete the cutting. The second conveyor assembly 17 is used to pull the welding strip and can control the length of the pulled welding strip, thereby enabling the cutting of welding strips of different lengths. The strips can then be inspected and collected for welding. Compared with the traditional operation of pulling and welding along with the solar panel, the welding strip quality can be detected in advance and the welding efficiency can be improved.

[0023] A finished plate 18 is provided above the processing table 8. A push plate 19 is slidably connected above the finished plate 18. A first slide rail 20 is provided above the base 1. A slider 21 is slidably connected to the front end of the first slide rail 20. A baffle 22 is provided at the front end of the slider 21. The cut welding strip is on the finished plate 18. Then the push plate 19 starts to slide backward on the finished plate 18, pushing the welding strip backward until it falls into the transfer chamber 24. At the same time, in order to prevent the round welding strip from falling into the transfer chamber 24 and continuing to roll down due to inertia when pushed in, the slider 21 is displaced on the first slide rail 20 and is flush with the transfer chamber 24. The baffle 22 prevents the welding strip from continuing to roll.

[0024] A second slide rail 23 is provided above the base 1. A transfer chamber 24 is provided at the sliding end of the second slide rail 23. When the welding strip in the transfer chamber 24 reaches the maximum quantity, it can slide backward on the second slide rail 23 to drive the welding strip to the next area.

[0025] A third slide rail 26 is provided above the base 1. A transfer frame 27 is slidably connected to the front end of the third slide rail 26. A second cylinder 28 is provided at the front end of the transfer frame 27. A controller 29 is provided at the air rod end of the second cylinder 28. A gripping bracket 30 is provided at the front end of the controller 29. A suction cup 31 is provided at the bottom of the gripping bracket 30. A conveyor belt 25 is provided above the base 1. The second cylinder 28 can drive the controller 29 to descend through the air rod. At this time, the gripping bracket 30 falls close to the welding strip in the transfer chamber 24. By controlling the suction cup 31 at the bottom of the gripping bracket 30 to suck air, the welding strip in the transfer chamber 24 can be adsorbed. Then it rises and moves forward through the third slide rail 26 to transfer the welding strip onto the conveyor belt 25 for conveying. At this time, the worker can inspect each welding strip to observe whether it is damaged or has quality problems that do not meet the requirements. It is highly practical.
