Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery tab cutting technology, and in particular to a battery tab cutting device. Background Technology
[0002] Battery tab cutting equipment is a specialized piece of equipment used in the lithium battery production process to precisely cut battery tabs. Battery tabs are the parts that extend from the positive and negative electrode plates of a battery, used to connect to external circuits.
[0003] Chinese patent CN220073420U discloses a lithium battery tab cutting device. It includes a base plate with support frames on both sides and a base in the middle. A support plate is mounted on the base, and a limit block is installed on the support plate. A blade is lifted and positioned on the support plate, located at the bottom center of the lifting plate. The two sides of the lifting plate are mounted on the support frames via sliders. The middle of the lifting plate is connected to the extension end of a cylinder. A clamping assembly is movably mounted on the side of the blade. This utility model provides a lithium battery tab cutting device that solves the problems of insufficient dimensional accuracy and low production efficiency in manual tab cutting.
[0004] However, when manufacturing battery tabs, the size and width of the battery tabs need to be determined according to the specific design requirements of the battery. The support plate and the limiting block of this device are connected by bolts, which has certain limitations. It can only limit the tabs of one width and cannot limit them according to the size and width of the battery tabs. Moreover, the clamping component of this device is only set on one side of the blade, which can only fix one side of the battery tab. During the cutting process, the other side that is not fixed may lift or curl up, resulting in poor stability and affecting the cutting of the battery tabs. Therefore, it is urgent to improve this device. Utility Model Content

[0064] Reference Figures 1 to 4 In a preferred embodiment, two moving mechanisms are provided, symmetrically arranged on the rotating mechanism and slidably connected to the U-shaped plate 3; the moving mechanism includes:
[0065] Two limiting rings 10 are provided, and the two limiting rings 10 are symmetrically arranged on the bidirectional screw 9 and rotatably connected to the bidirectional screw 9; they are used to drive the two connecting keys 5 to move towards each other, thereby driving the connecting mechanism and the lifting mechanism to move.
[0066] Two first movable posts 11 are provided, and the two first movable posts 11 are fixedly mounted on the limiting ring 10. The first movable posts 11 are slidably connected to the U-shaped plate 3. They are used to limit the rotation of the limiting ring 10, allowing the limiting ring 10 to move on the bidirectional screw 9.
[0067] Two connecting keys 5 are provided and fixedly mounted on the moving mechanism; they are used to connect the moving mechanism and the connecting mechanism, thereby causing the limiting ring 10 to drive the connecting mechanism and the lifting mechanism to move.
[0068] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, two connecting mechanisms are provided, each disposed on the connecting key 5 and fixedly connected to it; the connecting mechanism includes:
[0069] Two first fixing plates 12 are provided, and the two first fixing plates 12 are fixedly mounted on the connecting key 5; they are used to fix the position of the lifting mechanism and to drive the connecting column 13 to move, thereby driving the limiting mechanism to move, so that the limiting mechanism limits the battery tabs;

[0072] Two first electric telescopic rods 14 are provided, and the two first electric telescopic rods 14 are fixedly installed on the first fixed plate 12;
[0073] Two hollow sliding keys 15 are provided, and the two hollow sliding keys 15 are disposed on the first electric telescopic rod 14 and fixedly connected to the first electric telescopic rod 14.
[0074] Two first springs 16 are provided, and the two first springs 16 are disposed inside the hollow sliding key 15. The end of the first spring 16 near the first electric telescopic rod 14 is fixedly connected to the hollow sliding key 15.

[0077] Two pressure plates 19 are provided, which are disposed on the sliding cylinder 18 and fixedly connected to the sliding circular plate 17.
[0078] During operation, the first electric telescopic rod 14 is activated, releasing kinetic energy to lower the hollow sliding key 15. The hollow sliding key 15 then lowers the first spring 16, sliding disc 17, sliding cylinder 18, and pressure plate 19. When the pressure plate 19 contacts the battery tab, it experiences resistance, pushing the sliding cylinder 18 upward. The sliding cylinder 18 then causes the sliding disc 17 to slide within the hollow sliding key 15. The sliding disc 17 and the hollow sliding key 15 compress the first spring 16. When the first electric telescopic rod 14 is closed, the first spring 16 releases elastic potential energy, applying a downward force to the sliding disc 17, sliding cylinder 18, and pressure plate 19, thus fixing the battery tab with the pressure plate 19. The force generated by the elastic potential energy released by the first spring 16 is relatively small, thus reducing damage to the battery tab while effectively fixing it.
[0079] A fixing block 6 is fixedly mounted on the U-shaped plate 3; the fixing block 6 is rotatably connected to the bidirectional screw 9; it is used to fix the position of the cutting mechanism.

[0083] The cutting blade 22 is disposed on the second fixing plate 21 and is fixedly connected to the second fixing plate 21.
[0084] When in operation, the second electric telescopic rod 20 is activated. The second electric telescopic rod 20 releases kinetic energy to drive the second fixed plate 21 to descend. The fixed plate is used to transfer kinetic energy to drive the cutting blade 22 to move downward. The cutting blade 22 is used to cut the battery tabs.
[0085] Two second moving slots 7 are provided, and the two second moving slots 7 are symmetrically arranged on the cutting table 2; they are used to limit the position of the second moving column 23, thereby limiting the movement position of the limiting mechanism.
[0086] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, two limiting mechanisms are provided, which are disposed on the cutting table 2 and slidably connected to the cutting table 2. The limiting mechanisms include:
[0087] There are two second moving columns 23, which are disposed in the second moving groove 7 and are slidably connected to the cutting table 2;
[0088] Two limiting plates 24 are provided, and two limiting posts are fixedly mounted on the second movable post 23. The limiting plates 24 are fixedly connected to the connecting post 13. They are used to limit the position of the battery tabs.
[0089] Working principle: By placing the battery tabs on the cutting table 2, the first motor 8 is started. The first motor 8 drives the bidirectional screw 9 to rotate, which in turn drives the two limiting rings 10 to move towards each other. The two limiting rings 10 drive the two connecting keys 5 to move towards each other, which in turn drive the two first fixing plates 12 to move towards each other. The two first fixing plates 12 drive the two connecting columns 13 to move towards each other, which in turn drive the two limiting plates 24 to move towards each other, thus limiting the battery tabs. At the same time, the two first fixing plates 12 drive the two connecting columns 13 to move towards each other, and simultaneously drive the two lifting mechanisms to move towards each other. Among them, the first fixing plate 12 drives the first electric telescopic rod 14 to move, the first electric telescopic rod 14 drives the hollow sliding key 15 to move, the hollow sliding key 15 drives the first spring 16, the sliding circular plate 17 and the sliding cylinder 18 to move, and the sliding cylinder 18 drives the pressure plate 1... 9. Movement; Activate the first electric telescopic rod 14, which drives the hollow sliding key 15 to descend. The hollow sliding key 15 drives the first spring 16, sliding disc 17, sliding cylinder 18, and pressure plate 19 to descend. When the pressure plate 19 contacts the battery tab, the pressure plate 19 experiences resistance, pushing the sliding cylinder 18 upward. The sliding cylinder 18 drives the sliding disc 17 to slide within the hollow sliding key 15. The sliding disc 17 and the hollow sliding key 15 cooperate to compress the first spring 16. Activate the first electric telescopic rod 14. The first spring 16 releases its elastic potential energy, applying a downward force to the sliding disc 17, sliding cylinder 18, and pressure plate 19, thus fixing the battery tab with the pressure plate 19. Activate the second electric telescopic rod 20, which drives the second fixing plate 21 to descend. The second fixing plate 21 drives the cutting blade 22 to descend, cutting the battery tab.
