Battery film tearing device and method

Abstract

The invention relates to the technical field of battery production equipment, and provides a battery film tearing device and method. The battery film tearing device comprises two film tearing units and a cutting unit, wherein the two film tearing units are arranged to be fixed to the first tearing end and the second tearing end of an insulating film torn from one end of a battery respectively so as to tear the insulating film on the side part of the battery from the two sides of the battery in the length direction of the battery respectively; and the cutting unit is arranged to be capable of cutting the insulating film in the film tearing process of the two film tearing units so as to separate the insulating film at the bottom of the battery from the insulating film on the side part of thebattery. According to the battery film tearing device and method, the film tearing speed and the film tearing efficiency can be effectively improved, the convenience of film tearing is realized, thedifficulty of manual film tearing is reduced, the problems of battery collision and shell scratching caused by manual film tearing at present are solved, the secondary rework efficiency is improved, and subsequent film re-coating is facilitated.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to a battery tearing film device and a film tearing method. Background technique [0002] In the battery manufacturing process, in order to ensure the external safety performance, the insulating film is mainly used for insulation protection. However, in the process of battery coating, it is inevitable that there will be defective coating products such as bubbles, wrinkles, and unqualified insulation performance. Strict control, once there are air bubbles, wrinkles, and foreign matter, the coated battery needs to be re-coated, that is, it needs to be reworked twice. [0003] However, because the insulating film needs to meet the insulation requirements, it is firmly attached to the surface of the battery during the coating process, and its adhesiveness is relatively good. Cause problems such as battery bumps and scratches on the casing. In addition, there is c...

However, in the process of battery coating, it is inevitable that there will be defective coating products such as bubbles, wrinkles, and unqualified insulation performance. Strict control, once the coated battery with bubbles, wrinkles, foreign matter needs to be re-coated, that is, it needs to be reworked twice

[0003] However, because the insulating film needs to meet the insulation requirements, it is firmly attached to the surface of the battery during the coating process, and its adhesiveness is relatively good. Cause battery bumps, scratches and other problems

In addition, there is currently a lack of tooling equipment for battery tearing film on the market. Therefore, there is an urgent need for a film tearing equipment that can solve the bottleneck process of coating
