Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and in particular relates to a film tearing mechanism used in battery production. Background Art

[0002] In the prior art, a layer of film needs to be wrapped on the outer surface of the battery plastic shell before it comes off the production line to prevent scratches on the surface of the battery plastic shell due to friction or bumps during subsequent production and transportation, resulting in poor appearance; and, after the battery completes some production procedures, the film on the battery plastic shell needs to be torn off, so the film on the battery plastic shell must also be easy to tear off later.

[0003] In order to facilitate the subsequent tearing off of the film on the battery plastic shell, the conventional film wrapping method of the battery plastic shell is usually to first wrap a section of the film in a "[" shape on the side of the battery plastic shell, and then wrap another section of the film in a "]" shape on the side of the battery plastic shell, and the two sections of the film form a circle, thereby realizing the film wrapping operation of the battery plastic shell. However, the current film tearing method is still performed manually, which not only reduces the film tearing efficiency of the battery, but also is laborious and time-consuming, and also increases the labor intensity of the workers.
