Background

With the development of technology, the application electronics industry is being updated and upgraded, and Printed Circuit Boards (PCBs) are resin substrates made of acrylic resin, polycarbonate, and polyester amide. Since the surface of the resin substrate is easily attached by dust or contaminants, a thin film (protective film) such as Polyethylene (PE) or Polyethylene Terephthalate (PET) is disposed on the surface of the resin substrate, so as to prevent the printed circuit board from being contaminated by dust during the production process or during the circulation, and the protective film on the surface of the printed circuit board needs to be torn off during the next process production and assembly.

The process of tearing the membrane is accomplished on the market and is divided into two kinds of modes mostly, one kind is artifical tear film, and this kind of mode leads to intensity of labour great, and is high to operating personnel's dependency. The working efficiency is low, secondary pollution or product damage is easily caused to the product, the high-efficiency production requirement cannot be met, and the level of automatic production is reduced; the other is to realize automatic film tearing through a film tearing mechanism, the commonly used film tearing mechanism is directly pressed down through an adsorption component or an adhesive tape, so that the protective film is easily not torn completely, and even a product is driven to shift; in addition, the film tearing mechanism adopts a copybook mode, a driving mechanism is additionally required, the material cost of the copybook is high, the film tearing time is long, the whole mechanism occupies large space, and the follow-up maintenance is not facilitated.
