[0023] When producing some electronic products, it is necessary to set protective sheets on the outside. Protective sheets, such as mica sheets used in the production of integrated batteries, can effectively reduce the risk of thermal runaway of batteries, improve the safety and stability of batteries, while reducing battery weight, reducing material costs, and improving battery life, ensuring that the battery still maintains good insulation properties in high temperature environments; during the transportation of mica sheets or during transportation between production lines, in order to protect their surfaces, it is necessary to stick a protective film on their surfaces. Before the protective film is attached to the product, a release paper is attached to it. When the existing film tearing equipment tears off the release paper, the protective film is generally adsorbed by the suction cup. In the process of grabbing the edge of the release paper and tearing off the release paper, the protective film is often torn off the suction cup, or wrinkles are formed on the end of the protective film, affecting the subsequent pasting effect.
