Description

Technical Field

[0001] The utility model relates to the field of photovoltaic solder ribbon processing, in particular to a positioning device for photovoltaic solder ribbon processing. Background Technique

[0002] Photovoltaic solder ribbon is a core material in photovoltaic module manufacturing, mainly used to connect photovoltaic cells to achieve current collection and transmission. It consists of a copper substrate and a surface-coated tin-based solder layer, which are tightly combined through a special process. This material not only has good electrical conductivity but also excellent welding performance, ensuring stable connection between cells and thus improving the overall power generation efficiency of photovoltaic modules.

[0003] During the processing of photovoltaic solder ribbon, it is necessary to coat the tin-based solder on the surface of the copper substrate. After coating, the photovoltaic solder ribbon needs to be wound for packaging and handling. To ensure that the photovoltaic solder ribbon can be stably wound on the winding roller, a positioning device for photovoltaic solder ribbon processing is required.

[0004] Currently, when winding photovoltaic solder ribbon, due to the relatively smooth surface of the photovoltaic solder ribbon, it is difficult to be directly wound by the winding roller through friction in the first few turns. Current equipment usually directly fixes and connects the photovoltaic solder ribbon to the winding roller through a clamping device or glue. However, after winding, it is difficult to remove the photovoltaic solder ribbon from the winding roller, which is inconvenient for subsequent packaging and handling. Therefore, a positioning device for photovoltaic solder ribbon processing is proposed to solve the above problems. Summary of the Utility Model

The ramp block 3 can limit the left and right movement of the photovoltaic ribbon during winding and play a positioning role. The outer periphery of the left ramp block 3 is fixedly connected to the left end of the winding roller 2, the outer periphery of the right ramp block 3 is slidably connected to the right end of the winding roller 2, and the right ramp block 3 is fixedly connected to the left side of the right disk 4. Prismatic blocks 5 are fixedly connected to the outer sides of the left disk 1 and the right disk 4, and the prismatic blocks 5 can be connected to the bearing seats on the support frame to facilitate fixing the positioning device. A fixing port 6 is opened inside the winding roller 2, a limiting groove 7 is opened inside the winding roller 2, there are two sets of limiting grooves 7, which are symmetrically arranged front and back on the front and back inner walls of the fixing port 6. A spring groove 8 is opened inside the limiting groove 7, there are two sets of spring grooves 8, which are symmetrically arranged left and right on the left and right sides of the limiting groove 7. A limiting block 10 is elastically connected to the inside of the spring groove 8 through a limiting spring 9. When the limiting block 10 is not stressed, the limiting spring 9 will push the limiting block 10 backward. One end of the limiting spring 9 is fixedly connected to the inside of the spring groove 8, and the other end of the limiting spring 9 is fixedly connected to the inside of the limiting block 10. The outer periphery of the limiting block 10 is slidably connected to the inside of the limiting groove 7, and the limiting groove 7 restricts the limiting block 10 to only slide back and forth along the inner wall of the limiting groove 7. A fixing block 11 for conveniently fixing the photovoltaic ribbon is fixedly connected to the inside of the limiting block 10. A transverse groove is provided inside the fixing block 11 to increase friction. The outer periphery of the fixing block 11 is slidably connected to the inside of the limiting groove 7, and the limiting groove 7 restricts the fixing block 11 to only slide back and forth along the inner wall of the limiting groove 7.

[0033] Referring to Figures 4 - 5 , a triangular block 12 is in contact with the right side of the limiting block 10. The right end of the limiting block 10 is provided with an inclined surface, and the inner side of the triangular block 12 is an inclined surface, which fits with the inclined surface at the right end of the limiting block 10. When the triangular block 12 moves to the left, it can squeeze the limiting block 10 forward. A limiting component is arranged inside the right disk 4, and the limiting component is used to fix the right disk 4 and the winding roller 2. The limiting component includes a threaded column 13. There are six sets of threaded columns 13, which are evenly distributed in a ring inside the right disk 4. The outer periphery of the threaded column 13 is rotatably connected to the inside of the right disk 4. A tensioning block 14 is threadedly connected to the outer periphery of the threaded column 13. The outer side of the tensioning block 14 is in contact with the inner wall of the ramp block 3, and the ramp block 3 prevents the tensioning block 14 from rotating. When the threaded column 13 is rotated, the threaded column 13 will drive the tensioning block 14 to move left and right. A tensioning groove 15 is opened on the right side of the winding roller 2. The outer side of the tensioning block 14 is provided with an inclined surface, and the shape of the tensioning block 14 is adapted to the shape of the tensioning groove 15. The outer periphery of the tensioning block 14 is slidably connected to the inside of the tensioning groove 15. When the tensioning block 14 moves to the left, it will tighten along the inclined surface with the inner wall of the tensioning groove 15, and at the same time provide friction and clamping force to fix the right disk 4 and the winding roller 2.

[0034] Refer to Figure 1 , a rotating ring groove 16 is provided on the left side of the left disk 1. A sliding column 17 is slidably connected inside the rotating ring groove 16. The rotating ring groove 16 restricts the sliding of the sliding column 17 inside the rotating ring groove 16. A connecting rod 18 is fixedly connected to the outer periphery of the sliding column 17. One end of the outer side of the connecting rod 18 is rotatably connected to a positioning roller 19. The positioning roller 19 is parallel to the winding roller 2. The two ends of the positioning roller 19 are thicker and the middle is thinner, which can position the photovoltaic solder ribbon and prevent the photovoltaic solder ribbon from flipping. A support block 20 is fixedly connected to the left side of the positioning roller 19. The support block 20 can be connected to the bearing seat on the support frame, which is convenient for fixing the positioning device.

[0035] Working principle: When it is desired to conveniently fix the photovoltaic solder ribbon, one end of the photovoltaic solder ribbon is inserted into the inside of the fixing port 6, between the two fixing blocks 11, and then the right disk 4 is inserted. The triangular block 12 on the left side of the right disk 4 contacts the right inclined surface of the limiting block 10, squeezing the right inclined surface of the limiting block 10, causing the limiting block 10 to move inwards. The limiting block 10 drives the fixing block 11 to move inwards to clamp the photovoltaic solder ribbon. Then, the threaded column 13 is rotated to make the tensioning block 14 tighten along the inner wall of the tensioning groove 15 to fix the right disk 4. When the winding is completed, the threaded column 13 is rotated, the right disk 4 is removed, the fixing block 11 releases the photovoltaic solder ribbon inside the fixing port 6, and the wound photovoltaic solder ribbon is rotated one circle in the opposite direction of the winding direction, and then the photovoltaic solder ribbon can be conveniently removed. When winding the photovoltaic solder ribbon again, first fix the prism block 5 and the support block 20 inside the bearing seats of a group of support frames. During winding, ensure that the photovoltaic solder ribbon first passes through the bottom end of the positioning roller 19. The arc surface of the positioning roller 19 makes the photovoltaic solder ribbon located in the center of the positioning roller 19, preventing deviation. At the same time, the positioning roller 19 can prevent the photovoltaic solder ribbon from rotating and affecting the winding effect.
