Technical Field
[0001] This utility model relates to the technical field of silicon wafer string bonding, and in particular to a wire positioning structure. Background Technology
[0002] Photovoltaic silicon wafers are the core and most valuable component of a solar power system. Their function is to convert solar energy into electrical energy, which is then stored in batteries or used directly as a power source. In BC cells (back-contact cells, which can be combined with various circuits), the welding wires need to be positioned appropriately before string bonding. This requires cutting the long welding wires into segments and adjusting the distance between the segments according to the positions of the subsequent silicon wafers. Utility Model Content
[0003] One objective of this invention is to provide a welding wire positioning structure that cuts and separates longer welding wires according to the requirements for subsequent welding wire placement, thereby improving the efficiency of silicon wafer string bonding.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A welding wire positioning structure includes a welding wire positioning bracket. A welding wire positioning motor and a welding wire positioning driven wheel are mounted on both sides of the welding wire positioning bracket. A welding wire positioning drive wheel is connected to the drive end of the welding wire positioning motor. A welding wire positioning timing belt connects the welding wire positioning drive wheel on one side to the corresponding welding wire positioning driven wheel on the other side. Several welding wire positioning seats are arranged in the middle of the welding wire positioning bracket. Each welding wire positioning timing belt is connected to one welding wire positioning seat on both sides. A welding wire positioning clamp is hinged to each welding wire positioning seat. A hook plate moves laterally on the welding wire positioning seat in the middle. A welding wire cutter is arranged on one side of the hook plate, and the welding wire cutter moves vertically.
[0006] As a preferred technical solution, each side of the welding wire positioning bracket has three sets of welding wire positioning motors, and the number of welding wire positioning seats is twelve.
[0007] As a preferred technical solution, a positioning seat slide rail is fixed on the welding wire positioning bracket, and a positioning seat slider is fixed at the lower end of each welding wire positioning seat, and the positioning seat slider slides on the positioning seat slide rail.
[0008] As a preferred technical solution, a welding wire positioning cylinder is installed at the upper end of the welding wire positioning seat. A connecting rod is connected to the piston end of the welding wire positioning cylinder. A welding wire positioning plate is connected to the upper end of the connecting rod. A V-groove is provided on the welding wire positioning plate. The lower end of the welding wire positioning clamp is engaged in the V-groove.
[0009] As a preferred technical solution, a guide cylinder is installed inside the welding wire positioning seat, and a guide post is fixed at the lower end of the welding wire positioning plate, with the guide post moving within the guide cylinder.
[0010] As a preferred technical solution, a hook cylinder is laterally connected inside the welding wire positioning seat. A connecting arm is hinged to the driving end of the hook cylinder. The upper end of the connecting arm is connected to one end of the hook strip. The hook strip moves laterally on the welding wire positioning seat.
[0011] As a preferred technical solution, a wire guide plate is fixed on the wire positioning seat, and a wire guide groove is provided on the wire guide plate.
[0012] The beneficial effects of this utility model are as follows: It provides a welding wire positioning structure, which clamps and fixes the welding wire pulled out by the wire clamping structure and cuts it to an appropriate length. According to the subsequent placement position, the motors at both ends of the positioning bracket drive the positioning seat to perform position separation adjustment, which pre-processes the welding wire position during string welding.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1 to 6 As shown in this embodiment, a welding wire positioning structure includes a welding wire positioning bracket 1. Welding wire positioning motors 2 and welding wire positioning driven wheels 3 are installed on both sides of the welding wire positioning bracket 1. A welding wire positioning drive wheel 4 is connected to the drive end of the welding wire positioning motor 2. A welding wire positioning timing belt 5 connects the welding wire positioning drive wheel 4 on one side to the corresponding welding wire positioning driven wheel 3 on the other side. Several welding wire positioning seats 6 are provided in the middle of the welding wire positioning bracket 1. Each welding wire positioning timing belt 5 is connected to a welding wire positioning seat 6 on both sides. A welding wire positioning clamp 7 is hinged to the welding wire positioning seat 6. A hook strip 8 moves laterally on the welding wire positioning seat 6 in the middle. A welding wire cutter 9 is provided on one side of the hook strip 8 and moves vertically.
[0024] Specifically, in this embodiment, each side of the welding wire positioning bracket 1 has three sets of welding wire positioning motors 2, and the number of welding wire positioning seats 6 is twelve. Each set of welding wire positioning motors 2 pulls one welding wire positioning seat 6 on each side of the welding wire positioning synchronous belt 5. There are a total of six sets of welding wire positioning motors 2 on the left and right sides, which jointly control the movement of the twelve welding wire positioning seats 6.
[0025] After the long welding wire is pulled out, it is placed on the welding wire positioning seat 6. After the welding wire positioning clamp 7 clamps the welding wire, the horizontally moving hook plate 8 hooks the welding wire. Then the welding wire cutter 9 rises to cut the hooked welding wire. Then the welding wire positioning motor 2 provides power. Under the linkage of the welding wire positioning drive wheel 4 and the welding wire positioning driven wheel 3, the clamped and fixed welding wire segment is separated by each welding wire positioning seat 6 at a fixed distance to prepare for the subsequent removal of welding wire.
[0026] The welding wire positioning bracket 1 is fixed with a positioning seat slide rail 10, and the lower end of the welding wire positioning seat 6 is fixed with a positioning seat slider 11. The positioning seat slider 11 slides on the positioning seat slide rail 10. When the welding wire positioning seat 6 moves laterally, it is guided and friction is reduced by the sliding between the positioning seat slide rail 10 and the positioning seat slider 11.
[0027] A welding wire positioning cylinder is installed on the upper end of the welding wire positioning seat 6. The piston end of the welding wire positioning cylinder is connected to a connecting rod 12. The upper end of the connecting rod 12 is connected to a welding wire positioning plate 13. A V-groove 14 is provided on the welding wire positioning plate 13. The lower end of the welding wire positioning clamp 7 is engaged in the V-groove 14. The welding wire positioning cylinder controls the welding wire positioning plate 13 to move downward. As the V-groove 14 moves downward, the lower end of the welding wire positioning clamp 7 can be opened, while the upper end of the welding wire positioning clamp 7 will clamp the welding wire. The reverse action is the same.
[0028] The welding wire positioning seat 6 has a guide cylinder 15 installed inside, and a guide post 16 is fixed at the lower end of the welding wire positioning plate 13. The guide post 16 moves inside the guide cylinder 15 and is guided by the movement of the guide post 16 inside the guide cylinder 15 when the welding wire positioning plate 13 moves up and down.
[0029] The welding wire positioning seat 6 is connected to a hook cylinder in the middle. The drive end of the hook cylinder is hinged to a connecting arm 17. The upper end of the connecting arm 17 is connected to one end of the hook strip 8. The hook strip 8 moves laterally on the welding wire positioning seat 6. Under the action of the hook cylinder, the connecting arm 17 drives the hook strip 8 to move laterally, which hooks the welding wire that is clamped and fixed on the left and right in the upper and lower directions, making it easy to cut.
[0030] A wire guide plate 18 is fixed on the wire positioning seat 6. A wire guide groove 19 is provided on the wire guide plate 18. The wire can be easily aligned in the wire guide groove 19.
[0031] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
