During the production and processing of photovoltaic panels, punching operations are required to facilitate subsequent installation or meet other functional requirements.

[0003] Chinese Patent with the authorization announcement number CN221912673U discloses a punching device for photovoltaic cells. By placing the photovoltaic cells on the workbench, the screw nut is driven to move directionally by the rotating threaded rod to achieve the longitudinal movement of the punching assembly, and the moving block is driven to move directionally by the second electric telescopic rod to achieve the lateral movement of the punching assembly.

[0044] Among them, such as Figures 12-13As shown in the figure, a rectangular accommodation opening 505 is formed on the upper surface of the lifting plate 502; the rotating mechanism 8 includes a fifth motor 801 vertically bolted to the upper surface of the movable plate 606 and a plurality of U-shaped blocks 802 respectively bolted to the other ends of a plurality of bearing rods 710; the fifth motor 801 is a conventional servo motor in the art; the fifth motor 801 is in clearance fit with the inner side of the accommodation opening 505; the output shaft of the fifth motor 801 penetrates through the movable plate 606 with clearance and is vertically bolted with a driving block 803 having a T-shaped vertical cross-section; when any one of the bearing rods 710 is vertically arranged directly below the fifth motor 801, the driving block 803 can be slidably fitted into the U-shaped block 802 on the bearing rod 710. During use, the arrangement directions of the two side arms of the U-shaped block 802 on any one of the bearing rods 710 are consistent with the arrangement directions of the two extending protrusions 708 at the position of the bearing rod 710. When any one of the bearing rods 710 is vertically arranged directly below the fifth motor 801, the fifth motor 801 is driven to move downward by the movable plate 606, so that the driving block 803 is slidably fitted into the U-shaped block 802 on the bearing rod 710. Then, the fifth motor 801 drives the driving block 803 to rotate, so that the driving block 803 drives the drill bit 9 to rotate through the U-shaped block 802 and the bearing rod 710, thereby realizing the hole opening treatment of the photovoltaic panel, effectively ensuring the hole opening effect of the photovoltaic panel; in addition, the number of turns of the fifth motor 801 driving the driving block 803 to rotate each time is a positive integer, so that after the driving block 803 drives the U-shaped block 802 to stop rotating, the arrangement directions of the two side arms of the U-shaped block 802 on the bearing rod 710 are still consistent with the arrangement directions of the two extending protrusions 708 at the position of the bearing rod 710, effectively ensuring the connection accuracy between the driving block 803 and the U-shaped block 802.

[0045] In addition, as Figures 5-11As shown, the second gear 605 is an incomplete gear; a first rotating shaft 610 is vertically arranged on one side of the second gear 605; the upper end of the first rotating shaft 610 is rotatably connected to the lifting plate 502; a third gear 611 is key-connected to the outer periphery of the first rotating shaft 610; the third gear 611 can be meshed with the second gear 605; a third pulley 612 is key-connected to the lower end of the first rotating shaft 610; the third pulley 612 is connected to a fourth pulley 613 through a synchronous belt; the fourth pulley 613 is key-connected to the upper end of a second rotating shaft 614 coaxially arranged with the positioning cylinder 704; the second rotating shaft 614 is inserted into the positioning cylinder 704, and the upper and lower ends of the second rotating shaft 614 are respectively rotatably connected to the upper end of the positioning cylinder 704 and the disc cam 711; a fourth gear 615 is key-connected to the lower end of the second rotating shaft 614; a fifth gear 616 is meshed with the fourth gear 615; the axle of the fifth gear 616 is rotatably connected to the lower surface of the disc cam 711; an internal gear ring 617 is meshed with the fifth gear 616; the internal gear ring 617 is coaxially bolted to the lower edge of the rotating ring 702.During use, when the first gear 604 meshes with the second gear 605, the second gear 605 and the third gear 611 are in a non-meshing state. At this time, the second gear 605 drives the first gear 604 to rotate, realizing that the cylindrical cam 603 drives the driven column 609 to move upward. When the driven column 609 moves to the highest point, the first gear 604 and the second gear 605 are separated, and the second gear 605 meshes with the third gear 611. That is, at this time, the cylindrical cam 603 stops rotating, and the first spring 607 supports the rotating mechanism 8 to prevent the rotating mechanism 8 from moving downward due to its own weight. As the second gear 605 drives the third gear 611 to rotate, the third gear 611 drives the rotating ring 702 to rotate through the first rotating shaft 610, the third pulley 612, the fourth pulley 613, the second rotating shaft 614, the fourth gear 615, the fifth gear 616 and the internal gear ring 617, prompting a driving sleeve 709 to gradually approach the position directly below the rotating mechanism 8. When the driving sleeve 709 is vertically arranged directly below the rotating mechanism 8, the second gear 605 and the third gear 611 are separated, and the first gear 604 meshes with the second gear 605. At this time, the second gear 605 drives the first gear 604 to rotate, realizing that the cylindrical cam 603 drives the driven column 609 to move downward. When the driven column 609 moves to the lowest point, the middle teeth of the first gear 604 and the second gear 605 are meshed. At this time, the driving block 803 is slidably fitted in the U-shaped block 802 on the bearing rod 710 directly below it. Then, the fifth motor 801 drives the driving block 803 to rotate, realizing that the driving block 803 drives the drill bit 9 to rotate through the U-shaped block 802 and the bearing rod 710. When different drill bits 9 need to be replaced, the second gear 605 drives the first gear 604 to rotate, realizing that the cylindrical cam 603 drives the driven column 609 to move upward. When the driven column 609 moves to the highest point, the first gear 604 and the second gear 605 are separated, and the second gear 605 meshes with the third gear 611. The driving block 803 is removed from the U-shaped block 802 directly below it. At this time, the second gear 605 continues to rotate, and the second gear 605 drives the third gear 611 to rotate, realizing the switching of the drill bit 9. This not only effectively improves the linkage of the entire device but also improves the switching efficiency of the drill bit 9.
