AI Technical Summary
In the current lithium battery coating process, manual operation cannot ensure that the blue film is completely attached to the surface of the battery aluminum shell. There are air bubbles that are difficult to eliminate, and there is a risk of damaging the aluminum shell, which cannot meet the needs of mass production.
The battery cell surface coating fixture uses an unwinding assembly to release the film and a roller pressing assembly to roll the film tightly onto the battery cell surface, eliminating air bubbles. The positioning assembly and cutting groove ensure complete film adhesion and cutting, adapting to battery cells of different sizes.
It achieves efficient adhesion between the membrane and the battery cell, eliminates air bubbles, improves production efficiency, meets the needs of mass production, and avoids damage to the aluminum shell.
