Description

Technical Field

[0001] The invention belongs to the technical field of battery box film tearing, and in particular relates to a film removing device for battery box film tearing. Background Art

[0002] During the battery production process, in order to prevent the battery shell from being scratched and affecting the appearance and product quality, a protective film is usually wrapped around the side of the battery. When the battery that has completed the charging process on the production line is to be packaged and boxed, it is necessary to pre-process the battery before packaging and boxing. Among them, one of the processes in the pre-processing is to tear off the protective film on the side of the battery. Since it is difficult to find the film head in the film package during film tearing, it is difficult for mechanical equipment to perform the film tearing operation, so the film tearing work in this process is usually done manually.

[0003] Among them, if the film tearing operation is done manually, it is not only difficult to find the film head, but also the efficiency of manual operation is not high, resulting in the need for multiple workers on each battery production line to complete the battery film tearing work in time; resulting in problems such as low efficiency and high labor costs in the film tearing process. Although the existing film tearing equipment can also achieve the function of film tearing, it has problems such as overly complex structure, cumbersome operation, and low efficiency.

[0004] In view of the above-mentioned problems of low film tearing efficiency, complex equipment structure and high cost, the present invention designs a film removal device for battery box film tearing for battery boxes with half-side film application on both sides. Summary of the invention

[0005] The purpose of the present invention is to provide a film removal device for battery box film removal. Through the action of the film removal device, the negative pressure film suction assembly is moved to the film head of the film at the front end and the rear end surface of the battery box for negative pressure adsorption.
