[0022] Specifically, battery 4 is placed on placing frame 31 in fixed assembly 3, placing frame 31 can stabilize and support and fix battery 4, ensure that the position of battery 4 and tab body 41 on it is relatively fixed in subsequent operation, provide a basis for accurate bending operation, bending assembly 6 can move along slide rod two 52 in vertical adjustment assembly 5 in the vertical direction, by slide rod two 52, adjust bending frame 61 to the appropriate height position, so that it can accurately contact tab body 41, in order to carry out bending operation;

[0023] When the bending frame 61 is in place, the tab body 41 is located on one side of the limiting rod 62, and the electric telescopic rod 65 on the corresponding side is started to push the push plate 63 to move towards the limiting rod 62. Because the guide rod 64 on one side of the push plate 63 slides through the side wall of the bending frame 61, this enables the push plate 63 to move stably in the predetermined direction without deviation, and the push plate 63, under the push of the electric telescopic rod 65, exerts pressure on the tab body 41 located on both sides of the limiting rod 62, so that the tab body 41 is bent around the limiting rod 62, thereby realizing the bending operation of the tab. The limiting rod 62 serves as a support and reference for tab bending, ensuring the consistency of the bending angle and shape;

[0024] The electric telescopic rod 65 serves as the driving source of the push plate 63, and its output force and stroke can be accurately adjusted and controlled through the control system. This enables accurate application of appropriate bending force and control of the bending degree when bending tab bodies 41 of different materials, thicknesses and sizes according to actual needs, further improving the bending accuracy.
