This cutting device consists of an upper cutter and a lower cutter, with multiple lower cutters fixed in place by bolts. Therefore, when the sharpness of the lower cutter decreases, it needs to be replaced, requiring loosening of multiple bolts and tightening again after replacing the lower cutter. This makes replacing the lower cutters in this cutting device quite cumbersome. To address this, we provide a cutting structure for silicon wafers after welding. Utility Model Content

[0026] like Figures 1-4As shown, this utility model provides a technical solution: a silicon wafer post-welding cutter structure, comprising: a main body mechanism 1, the main body mechanism 1 including a bracket 11, a fixed plate 12 fixedly connected to the top of the bracket 11, a lower cutter 13 provided in a placement groove on the fixed plate 12, a pressure plate 14 provided at the top of the fixed plate 12, an upper cutter 15 provided at the bottom of the pressure plate 14, an auxiliary mechanism 2 provided inside the fixed plate 12, the auxiliary mechanism 2 including a threaded rod 21, the threaded rod 21 being sleeved inside the fixed plate 12, a threaded block 22 being sleeved on the outer surface of the threaded rod 21, the threaded block 22 being threadedly connected to the threaded rod 21, a threaded rod 23 being provided on one side of the threaded rod 21, the threaded rod 23 being sleeved inside the fixed plate 12, a threaded block 24 being sleeved on the outer surface of the threaded rod 23, the threaded block 24 being threadedly connected to the threaded rod 23, and a movable plate 25 being fixedly connected to the top of both the threaded block 22 and the threaded block 24. A locking post 26 is fixedly connected to the outer surface of the plate 12. The locking post 26 is sleeved inside the lower cutter 13 and is slidably connected to the lower cutter 13. A transmission gear 27 is sleeved on the outer surface of threaded rod 1 21 and threaded rod 23. The transmission gear 27 is fixedly connected to threaded rod 1 21 and threaded rod 23. A transmission belt 28 is sleeved on the outer surface of the transmission gear 27. Threaded block 1 22 and threaded block 24 are sleeved inside the fixed plate 12 and are slidably connected to the fixed plate 12. Bearings 29 are sleeved on the outer surface of threaded rod 1 21 and threaded rod 23. The bearings 29 are placed in a groove opened inside the fixed plate 12 and are fixedly connected to the inner wall of the fixed plate 12. The bearings 29 are fixedly connected to the outer surface of threaded rod 1 21 and threaded rod 23. A motor 201 is fixedly connected to one end of threaded rod 1 21. The motor 201 is sleeved inside the fixed plate 12 and is fixedly connected to the fixed plate 12.

[0027] In this embodiment, a threaded rod 21 is provided, which can drive the threaded block 22, while a threaded rod 23 can drive the threaded block 24. This allows the threaded blocks 22 and 24 to reciprocate, thereby controlling the positions of the moving plate 25 and the locking post 26. This enables the moving plate 25 and the locking post 26 to simultaneously control multiple lower cutters 13 and ensure the stability of the lower cutter 13's position. Transmission gears 27 are provided, with two gears 27 respectively sleeved on the outer surfaces of the threaded rod 21 and the threaded rod 23. With the cooperation of the transmission belt 28, the threaded rod 21 and the threaded rod 23 can rotate simultaneously, driving the threaded blocks 22 and 24. Furthermore, an upper cutter 15 is provided, which can cooperate with the lower cutter 13 to cut the solder strips of the welded solar cells.

[0028] Example 2

[0029] like Figures 1-4 As shown, a cylinder 16 is fixedly connected inside the bracket 11. A floating joint 17 is fixedly connected to one end of the cylinder 16. A pull rod 18 is fixedly connected to the end of the floating joint 17 away from the cylinder 16. The pull rod 18 is fixedly connected to the pressure plate 14. A linear guide rail 19 is provided on one side of the pull rod 18. The linear guide rail 19 is fixedly connected to the fixed plate 12. A slider 101 is sleeved on the outer surface of the linear guide rail 19. The slider 101 is slidably connected to the linear guide rail 19. The slider 101 is fixedly connected to the pull rod 18. Bolts 102 are sleeved inside the pressure plate 14 and the upper cutter 15. The bolts 102 are slidably connected to the upper cutter 15. The bolts 102 are threadedly connected to the pressure plate 14.

[0030] In this embodiment, by setting up a cylinder 16, a floating joint 17, and a pull rod 18, and by using the three together, the pressure plate 14, which is fixedly connected to the pull rod 18, can drive the upper cutter 15 to move up and down, thereby achieving the purpose of cutting the welding strip. A linear guide rail 19 is set up, and the slider 101 is sleeved on the outer surface of the linear guide rail 19. In this way, the linear guide rail 19 can guide the movement of the pull rod 18 by guiding the slider 101, ensuring that the pull rod 18 does not deviate from the driving of the pressure plate 14.

[0031] Working principle:

[0032] like Figures 1-4 As shown, in use, multiple lower cutters 13 can be installed in the placement slots on the fixed plate 12, and the lower cutters 13 can be kept stable. Then, the motor 201 is started, which drives the threaded rod 21 to rotate. When the threaded rod 21 rotates, it drives the transmission gear 27 fixedly connected to it to rotate. The transmission gear 27, in turn, drives the transmission gear 23 fixedly connected to it to rotate simultaneously with the transmission belt 28. Thus, the threaded rod 21 and the threaded rod 23 can rotate simultaneously, allowing the threaded block 22 and the threaded block 24 to move simultaneously, and causing the moving plate 25 and the locking post 26 to gradually approach the lower cutter. 13. Continue until the clamping post 26 is fully inserted into the lower cutter 13 and the lower cutter 13 is fixed to ensure its stability. Then, place the solder strips from the strings of solar cells to be cut on top of the fixing plate 12 and the lower cutter 13. Then, start the cylinder 16. With the cooperation of the floating joint 17, the cylinder 16 will drive the pull rod 18 to move. At the same time, the pull rod 18 will drive the pressure plate 14 and the upper cutter 15 to move down until the upper cutter 15 and the lower cutter 13 work together to cut the solder strips appropriately. If the upper cutter 15 needs to be replaced, the threaded connection between the bolt 102 and the pressure plate 14 can be released, and the upper cutter 15 can be replaced.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
