[0023] Refer to Figures 1-4 , a clamping and controlling device for a photovoltaic solder ribbon, including a bottom frame 1. Clamping grooves 2 are opened on the left and right sides of the bottom frame 1. A limiting groove 3 is opened on the top of the bottom frame 1. First motors 4 are fixedly connected to the front and back of the bottom frame 1. The first motors 4 are drivingly connected to a first threaded rod 5 at a position close to the center of the bottom frame 1. The first threaded rod 5 is provided to adjust the position of the control frame 6 for adapting to the model of the photovoltaic panel. The first threaded rod 5 is connected to the limiting groove 3 by a bearing. An adjusting block 9 is threadedly connected to the outer surface of the first threaded rod 5. A control frame 6 is fixedly connected to the top of the adjusting block 9. Stabilizing blocks 7 are fixedly connected to the bottom of the control frame 6 at positions close to the left and right sides. The stabilizing blocks 7 are provided to improve the stability of the control frame 6 during use and can provide a certain supporting effect. Movable wheels 8 are connected to the stabilizing blocks 7 by bearings at positions close to the center of the bottom frame 1. The movable wheels 8 are movably sleeved inside the clamping grooves 2. A second motor 10 is fixedly connected to the front of the control frame 6 at a position close to the right side. A rubber conveying wheel 14 is drivingly connected to the back of the second motor 10. A fitting wheel 15 is provided on the top of the rubber conveying wheel 14. The top of the rubber conveying wheel 14 is in contact with the bottom of the photovoltaic solder ribbon 11. A restricting groove 12 is opened inside the control frame 6. A conveying block 13 is movably sleeved inside the restricting groove 12.

[0024] Refer to Figures 1-4As described above, a second threaded rod 16 is connected to the inner bearing of the limiting groove 12. The outer surface of the second threaded rod 16 is threadedly connected to the conveying block 13. An arc-shaped groove 19 is formed inside the conveying block 13. A photovoltaic solder ribbon 11 is movably sleeved inside the arc-shaped groove 19. A connecting plate 20 is fixedly connected to a position near the middle on the left side of the conveying block 13. Limiting frames 22 are fixedly connected to the front and back of the connecting plate 20. The provision of the limiting frames 22 can also limit the photovoltaic solder ribbon 11. A rolling wheel 21 is connected to the inner side of the limiting frame 22 near the top on the left side of the connecting plate 20 by a bearing. The outer surface of the rolling wheel 21 is in contact with the top on the left side of the connecting plate 20. An arc-shaped opening 18 is formed at a position near the left side of the arc-shaped groove 19.

[0025] In the present utility model, during use, the photovoltaic solder ribbon 11 can be inserted into the limiting groove 12 through one side of the control frame 6 for feeding. Then, according to the model of the photovoltaic panel, the first motor 4 is controlled to drive the first threaded rod 5 to rotate.

After adjusting to a suitable position, the third motor 17 can be driven to drive the second threaded rod 16 to rotate. Through the limiting effect of the limiting groove 12 on the conveying block 13, the conveying block 13 is moved to the rightmost end. Then, the second motor 10 drives the rubber conveying wheel 14 to convey the photovoltaic solder ribbon 11. Due to the provision of the arc-shaped opening 18, the situation that the photovoltaic solder ribbon 11 gets stuck outside the conveying block 13 is avoided. The photovoltaic solder ribbon 11 then enters the arc-shaped groove 19 through the arc-shaped opening 18, and then moves to the top of the rolling wheel 21 through the arc-shaped groove 19. Then, the third motor 17 drives the second threaded rod 16 to control the conveying block 13 to move leftward. At the same time, the second motor 10 drives the matching wheel 15 to push the photovoltaic solder ribbon 11. Then, the welding equipment welds the photovoltaic solder ribbon 11 on the top of the rolling wheel 21 to the photovoltaic panel. At the same time, the third motor 17 drives the second threaded rod 16 to control the conveying block 13 to gradually move rightward to achieve stable welding first.
