Description

Technical Field

[0001] The utility model relates to the field of lithium battery assembly, in particular to a battery core shell inserting tool. Background Art

[0002] When assembling a lithium battery, the cell needs to be pushed into the casing.

[0003] Due to the low assembly precision of the battery cell and the shell, the assembly process is prone to problems such as tape stuck in the shell, Mylar film stuck in the shell, the battery cell being pinched by the shell, and the battery cell being damaged by the shell mouth deforming and entering the shell.

[0004] In the related technology, through personnel training, rework of the tape and high-temperature film sandwiched cells, high-temperature film guides are added around the shell insertion tooling, and a suction nozzle is used to expand the shell at the shell opening, thereby reducing the possibility of assembly problems. However, the high-temperature film is damaged and added to the shell, becoming a foreign object in the cell. At the same time, there is still a risk of the cell being pinched after the cell is offset.
