When producing electronic products, this layer of film needs to be removed. The existing tear film device generally first lifts the film at a corner of the sheet material, then clamps the film with a clamping device and tears the film. If the product size is large, the single tear film head is diagonal, which requires more space for tearing the film. The tear film equipment occupies a large working space, causing unnecessary waste of working space. At the same time, the tear film component of the existing tear film equipment is at the same angle as the edge of the product, especially the corner, which increases the difficulty of film lifting.
