Background

Fine electronic devices are generally protected by being covered with a film, and different electronic devices have different requirements on film quality. In the production of the film pasting production line, a plurality of layers of materials with required functions need to be pasted together firstly, and the composite film is cut into a corresponding shape through a cutter.
