ASSEMBLY DEVICE FOR BATTERY CELL

The present application provides an assembly device for a battery cell, and relates to the technical field of battery manufacturing. The assembly device for a battery cell comprises a supporting member and a pressing-down mechanism. The supporting member is configured to support an end cap of the battery cell. The pressing-down mechanism is arranged above the supporting member, and the pressing-down mechanism is configured to press down a housing of the battery cell to enable the housing to fit with the end cap, so that the end cap closes off an opening. The supporting member is configured to support the end cap, so that an open end of the housing covers over the end cap, and the pressing-down mechanism above the supporting member presses down a wall of the housing opposite the opening to enable the open end of the housing to fit with the end cap, and thus the end cap closes off the opening of the housing. Therefore, during assembly of the end cap and the housing, the opening of the housing is downward, so that dust does not easily fall into the housing, thus ensuring the cleanliness of a battery interior and improving the quality of the battery cell. In addition, the supporting member supports the end cap, so that the structure of the assembly device for a battery cell can be simplified, and the equipment cost can be reduced.
