[0069] In the above-mentioned implementation process, when the material transport structure 110 transports the battery assembly 30 to the top of the shell 40, the material transport structure 110 is first fixed to the combined table through the cooperation of the support column 2101 and the locking member 2102 to ensure the positioning and fixation of the battery assembly 30 before entering the shell, which is beneficial to the assembly accuracy of the battery assembly 30 and the shell 40, reduces the possibility of collision when the battery assembly 30 is placed in the shell 40, and has high assembly efficiency and high assembly consistency.

The shell 40 is fixed by the fixing block 2104, and the material transport structure 110 is fixed by the support column 2101 and the locking member 2102, which is beneficial to the positioning between the shell 40 and the battery assembly 30, improves the assembly accuracy of the battery assembly 30 and the shell 40, reduces the possibility of collision when the battery assembly 30 is placed in the shell 40, and has high assembly efficiency and high assembly consistency.

[0071] The principle of the battery assembly 30 box-entering assembly device is that after the transport mechanism 10 and the support mechanism 20 are combined and positioned, the battery assembly 30 in the form of CTP is ensured by the clamping structure to ensure that the size of the battery assembly 30 remains unchanged during transportation and movement, and the battery assembly 30 can be squeezed to achieve the clearance of the battery assembly 30 into the shell. The transport structure 110 ensures that the battery assembly 30 is pressed downward by controlling the pressure to achieve the height control of the battery assembly 30 into the shell, thereby meeting the design requirements for shell entry and satisfying the manual assembly conditions.
