[0024] Furthermore, a connecting seat 14 is connected to the bottom of the placement platform 1 , and the lifting drive member 5 is a lifting cylinder whose driving end is connected to the connecting seat 14 .

[0025] like Figure 2 and 3 As shown, the centering and positioning assembly 2 includes two side clamps 21 arranged opposite to each other, a rotating arm 22 and a first driving member 23, wherein the side clamps 21 are connected to a first slide 24 having a slide groove 241, and the first slide 24 is slidably connected to the bottom surface of the base plate 11 through a slide rail arranged along the second direction; the rotating arm 22 is rotatably arranged on the connecting seat 14, and the two ends of the rotating arm 22 are connected to slide rods 25, and the two slide rods 25 are respectively slidably arranged in two slide grooves 241; the first driving member 23 drives the rotating arm 22 to rotate relative to the placement platform 1, so that the two slide rods 25 drive the two first slides 24 to slide toward or away from each other along the second direction, thereby driving the two side clamps 21 to move toward or away from each other along the second direction. In this embodiment, the first driving member 23 is preferably a servo motor.

[0026] In the centering and positioning assembly 2, the connection position of the side clamping plate 21 on the first slide 24 is adjustable along the second direction. A long first adjustment hole is provided on the side clamping plate 21, and a first locking screw is provided in the first adjustment hole, and the first locking screw is screwed to the first slide 24. In this embodiment, the two side clamping plates 21 are arranged rotationally symmetrically along the rotation center axis of the rotating arm 22; the two first slides 24 are also arranged rotationally symmetrically along the rotation center axis of the rotating arm 22; and the two slide bars 25 are symmetrically arranged along the rotation center axis of the rotating arm 22.

[0027] In the centering and positioning assembly 2 , a first hollow groove 211 is formed on the positioning surface of the side clamping plate 21 to prevent the side clamping plate 21 from being adsorbed and attached to the battery cell 100 , which is not conducive to the separation of the two.

[0028] When in use, driven by the first driving member 23 , the rotating arm 22 rotates, driving the two first slide seats 24 to move toward each other, so that the two side clamping plates 21 move toward each other together to center and position the battery cell 100 .
