[0057] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] like Figures 1 to 5 As shown, this embodiment proposes a busbar punching device for a photovoltaic pressure-proof lead welding machine, including a support platform 1, a support seat 2, a pressing mechanism, a punching mechanism, a punching tool 3, a feeding mechanism, a guide assembly and a limit plate 4. The support seat 2 is fixedly connected to the support platform 1, the pressing mechanism is installed on the support platform 1, the punching mechanism is installed on the support platform 1, the punching mechanism is located below the pressing mechanism, the punching tool 3 is located above the support platform 1, the feeding mechanism is installed on the support platform 1, the guide assembly is installed on the support seat 2, and the limit plate 4 is slidably connected to the support seat 2. Through the pressing mechanism and the punching mechanism, the punching mechanism and the punching tool 3 can be pressed onto the busbar to punch out holes of appropriate sizes, and at the same time, right angles on both sides of the busbar head are punched out, and circular arc edges are punched out on both sides of the entire busbar head to prevent the right angles on both sides of the busbar head from being easily scratched with the holes in the back glass, causing the busbar to be skewed and pressed into the component, affecting the quality of the component. The feeding mechanism can improve the loading efficiency and also improve the punching efficiency.

[0059] Among them, such as Figure 1-2 As shown, the pressing mechanism includes a mounting frame 5, a threaded rod 6 and a motor 7. The mounting frame 5 is fixedly connected to the support platform 1. There are multiple threaded rods 6, and the multiple threaded rods 6 are rotatably connected between the mounting frame 5 and the support platform 1. There are multiple motors 7, and the multiple motors 7 are fixedly connected to the top of the mounting frame 5. The output ends of the multiple motors 7 are respectively fixedly connected to the multiple threaded rods 6. The pressing mechanism drives the threaded rods 6 to rotate through the motor 7, and drives the fixed plate 8 to move in the vertical direction.

[0060] Secondly, if Figure 2 As shown, the punching mechanism includes a fixed plate 8, a tool assembly and a punching matching assembly. The fixed plate 8 is threadedly connected to a plurality of threaded rods 6, the tool assembly is installed at the bottom end of the fixed plate 8, and the punching matching assembly is installed on the fixed plate 8. The punching mechanism punches out suitable holes through the tool assembly, as well as punches out arc-shaped edges for the busbars. The punching matching assembly is used to ensure that the direction of the punching process does not deviate and to ensure the quality of punching and edge punching.

[0061] Again, as Figure 4As shown, the tool assembly includes an optical axis 9, a tool limit block 10, a punching tool 3 and a chamfering tool 12. The optical axis 9 is fixedly connected to the fixed plate 8, the tool limit block 10 is fixedly connected to the end of the optical axis 9, the punching tool 3 is fixedly connected in the tool limit block 10, and the chamfering tool 12 is fixedly connected in the tool limit block 10. The punching tool 3 is used for punching, and the chamfering tool 12 processes the arc edge of the busbar while punching to avoid skewness of the busbar during use, and with high efficiency.

[0062] Among them, such as Figure 2 As shown, the punching fitting assembly includes a sleeve fixing block 13 and a backing plate 14 . The sleeve fixing block 13 is fixedly connected to the bottom end of the tool limiting block 10 , and the backing plate 14 is detachably connected to the fixing plate 8 .

[0063] Secondly, if Figure 2-3 As shown, the loading mechanism includes a mounting plate 15, a transmission component and a loading limit component. The mounting plate 15 is fixedly connected to the support platform 1, the transmission component is installed on the support platform 1, and the loading limit component is installed on the support seat 2. The loading mechanism transmits the busbar to the support seat 2 through the transmission component. The loading limit component and the guide component cooperate to make the position of the busbar after loading more accurate.

[0064] Again, as Figure 3 As shown, the transmission component includes a transmission shaft 16, a conveyor belt 17 and a second motor 18. There are two transmission shafts 16. The two transmission shafts 16 are rotatably connected to the mounting plate 15. The conveyor belt 17 is transmission-connected between the two transmission shafts 16. The second motor 18 is fixedly connected to the mounting plate 15. The output end of the second motor 18 is fixedly connected to the transmission shaft 16. When the second motor 18 is started, it drives the transmission shaft 16 to rotate, thereby driving the conveyor belt 17 to work and transport the busbar.

[0065] Among them, such as Figure 5 As shown, the loading limit assembly includes a limit groove and a spring 19. The limit groove is opened on the support seat 2, and the limit plate 4 is slidably connected to the support seat 2. There are multiple springs 19, and one end of the multiple springs 19 is fixedly connected to the bottom end of the limit groove, and the other end of the multiple springs 19 is fixedly connected to the limit plate 4. The conveyor belt 17 conveys the bus bar to the support seat 2. When the bus bar presses against the limit plate 4, it is a suitable chamfer position. When punching, the limit plate 4 can be retracted into the limit groove under the action of the spring 19 without affecting the punching operation.

[0066] Secondly, if Figure 3As shown, the guide assembly includes an electric telescopic rod 20 and a guide plate 21. There are multiple electric telescopic rods 20, and the multiple electric telescopic rods 20 are divided into two groups. Two groups of electric telescopic rods 20 are fixedly connected to both sides of the support base 2. There are two guide plates 21, and the two guide plates 21 are slidably connected to the support base 2. The two guide plates 21 are respectively fixedly connected to the output ends of the two groups of electric telescopic rods 20. The electric telescopic rods 20 are continuously pushed from both sides to the middle according to the size of the busbar, and can be corrected when the busbar moves in the wrong direction, thereby ensuring the accuracy of the punching hole position.

[0067] Finally, if Figure 3 As shown, when the chamfering tool 12 is pressed down, a part of the chamfering tool 12 contacts the limit plate 4, so that the chamfering tool 12 pushes the limit plate 4 down while punching the arc-shaped edge. After playing a positioning role, the limit plate 4 is received into the limit groove without affecting the arc-shaped edges pressed out on both sides of the busbar head.

[0068] In this embodiment, during operation, the busbar is first conveyed to the support seat 2 via the conveyor belt 17, the electric telescopic rod 20 is started, and the guide plate 21 is used to move it in the center, and finally it supports the limit plate 4. At this time, the motor 7 is started, driving the threaded rod 6 to rotate, thereby driving the fixed plate 8 and the tool and other structures to move downward. After the sleeve fixing block 13 contacts the busbar, the punching tool 3 and the chamfering tool 12 continue to press down to punch the hole, and continue downward along the knife hole position until a suitable hole is punched out in the busbar. At the same time, the right angles on both sides of the busbar head are also punched out, and circular arc edges are punched out on both sides of the entire busbar head.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
