[0026] Workbench 100;

[0027] A first positioning assembly 200, the first positioning assembly 200 is detachably disposed on the workbench 100;

[0028] The clamping assembly 300 is movably arranged on the opposite surface of the first positioning assembly 200, and cooperates with the first positioning assembly 200 to form a space for placing the battery pack 600. The clamping assembly 300 includes a clamping member 310 that moves relative to the first positioning assembly 200, and a limit plate 320 that is detachably arranged on the clamping member 310, and the limit plate 320 is provided with a plurality of protrusions 321. When the limit plate 320 abuts against the battery pack 600, the protrusions 321 are embedded in the battery pack 600 to form a concave-convex fit therewith. On the one hand, the groove on the battery pack end cover 620 can be filled, thereby preventing the battery pack end cover 620 from being deformed during the clamping process, effectively ensuring the performance of the battery pack 600; on the other hand, the movement of the battery pack 600 in the Y-axis and Z-axis directions can be limited, ensuring the stability of the battery pack 600 during the clamping process.

[0029] Specifically, if Figures 1 to 3 As shown, in this embodiment, the workbench 100 is rectangular, and a placement surface 101 is provided on the side facing away from the ground for carrying components such as the first positioning assembly 200 and the pressing assembly 300.

[0030] In order to realize the pressing operation on the battery pack 600, in this embodiment, the placement surface 101 is provided with a first positioning assembly 200 and a pressing assembly 300 arranged opposite to each other, the first positioning assembly 200 is detachably connected to the placement surface 101, the pressing assembly 300 is movably connected to the placement surface 101, and the first positioning assembly 200 and the pressing assembly 300 cooperate to form a space for placing the battery pack 600, so as to press the battery pack 600 in the space. The movable design of the pressing assembly 300 enables it to be applicable to battery packs 600 of different sizes, thereby improving the flexibility and versatility of the device.
