[0051] The cross-section of the guide sleeve 222 is rectangular, and the guide sleeve 222 is rotatably installed with a guide roller 25. In the embodiment of the present application, there are two groups of guide rollers 25 distributed along the length direction of the guide sleeve 222.

The vertical movement of the steel cable of the electric hoist 23 is mainly automatically controlled by the end limiter located on the steel cable winding drum, which fully ensures the safety of use and is conducive to realizing the precise control of the vertical movement of the clamping fixed seat 1. With the setting that the guide roller 25 is easy to disassemble and assemble, it is convenient for the guide roller 25 to always stably guide the vertical guide rod 24, so as to fully ensure the smooth stability of the clamping fixed seat 1 when moving in the vertical direction.

[0054] The horizontal moving mechanism includes a horizontal guide rail 36, a horizontal slider 37 and a horizontal roller 38, wherein two horizontal guide rails 36 are arranged in parallel.

One of the horizontal sliders 37 is provided with a rotating motor (not shown in the figure) that drives one of the horizontal rollers 38 to rotate, so that when the rotating motor drives one of the horizontal rollers 38 to rotate, the horizontal slider 37 drives the vertical fixing part 221 to move horizontally along the x-axis direction.

[0055] In order to fully ensure the stability of the vertical fixing part 221 when it moves along the x-axis direction to the position where it is clamping the formed battery pack, the horizontal slider 37 is provided with a pressing assembly, which includes a pressing cylinder 39 and a pressing block 40, wherein the pressing cylinder 39 is vertically mounted on the horizontal slider 37, and the pressing block 40 is fixedly mounted on the piston rod of the pressing cylinder 39.
