[0002] A battery pack is an essential component of a new energy automobile, and the battery pack of the new energy automobile mainly comprises battery monomers and a shell. A plurality of battery monomers are combined into a module, and the plurality of modules are combined and fixed in the shell to form the battery pack. At present, the material of the battery pack shell of the new energy automobile is aluminum alloy or steel, and a protective coating needs to be coated on the surface of the battery pack shell.

[0003] When the battery pack shell is sprayed with a coating, the battery pack shell needs to be clamped and positioned. However, the specifications of the battery pack shell are various, such as a blade battery pack and a square shell battery pack. Different clamps are needed to clamp different battery pack shells, so that it is more troublesome to spray different battery pack shells. SUMMARY

[0006] By adopting the technical scheme, the battery pack shell is placed between the fixed seat and the moving seat and is positioned against the fixed seat and the base, then the driving assembly drives the moving seat and the clamping seat to approach the fixed seat, in the initial state, i.e. before the clamping seat contacts the battery pack shell, the elastic buffer assembly is in the elongated state, thus the clamping seat can contact and press the battery pack shell earlier, then the moving seat continues to approach the battery pack shell, the moving seat moves and presses the elastic buffer assembly, thereby increasing the clamping force of the clamping seat on the battery pack shell, and after the clamping force reaches a certain value, the driving assembly stops driving the moving seat to move and positions the moving seat and the clamping seat, thus various battery pack shells can be clamped by the detection of the clamping force, and the clamping force is stable, thereby improving the convenience and stability of the battery pack shell during spraying.

[0007] The elastic buffer assembly can buffer when the clamping seat clamps the battery pack shell, reduces the risk of damaging the battery pack shell due to excessive impact force, and also reduces the risk of damaging the pressure detection structure when the clamping seat clamps the battery pack shell, making the clamping process more convenient and stable, and further improving the convenience and stability during spraying.

[0008] Meanwhile, the moving speed of the moving seat and the clamping seat is adjusted according to the clamping force of the clamping seat on the battery pack shell, when the clamping seat is not in contact with the battery pack shell, no pressure is generated, in this process, the moving speed of the clamping seat and the moving seat is fast, which can save time, when the clamping seat generates a clamping force on the battery pack shell, the moving speed of the clamping seat and the moving seat is slowed down, and the impact force generated on the battery pack shell and the pressure detection structure is greatly reduced by the buffering of the elastic buffer assembly, thereby improving the convenience of the battery pack shell during spraying and reducing the risk of damage to the battery pack shell.
