Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a processing device for lithium battery film pasting. Background Art

[0002] Membrane materials are important materials for lithium batteries. Membrane materials include base film and release film on the surface. The base film and release film need to be separated before use.

[0003] Chinese utility model patent CN221835620U discloses a lithium battery film laminating device. The device is equipped with a battery cell conveying module, a storage bin module, a film laminating module, a membrane separation module, and a waste material recovery module. The storage bin module includes an adsorption component and a storage bin component. The storage bin component stores the film material. The adsorption component absorbs the film material from the storage bin component and transfers it to the film laminating module. The tray component supports the remaining film material. After the film laminating module takes the film material, it uses the membrane separation module to tear off the release paper and put it into the waste material recovery module, then rotates 90 degrees to apply the bottom film to the battery cell. An anti-fool plate is also provided inside the storage bin to prevent the film material from being placed in the wrong direction. Although this technical solution sets an anti-fool plate to prevent the film material from being placed in the wrong direction, the anti-fool plate cannot correct the position deviation of the film material during the adsorption and material transfer stages, thereby affecting the efficiency of subsequent release paper separation.
