Description

film tearing machine

This creation relates to a film tearing machine, especially one that can effectively shorten the length so that it can be smoothly installed in a workshop with a smaller indoor length.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the upper and lower surfaces of the substrate, respectively. After exposure, the film is peeled off to make the photoresist layer. The layers are exposed for subsequent development and etching procedures. The existing method of peeling off the film by a film tearing machine is mainly to use an embossing wheel to roll the film on the surface of the film, and then use a sticky wheel to peel off the film. However, during the rolling process of the embossing wheel, it is easy to damage the photoresist layer and the substrate due to the excessive force of the rolling force.

Therefore, as shown in the patent case of "Automatic Film Peeling Machine and Film Peeling Method" No. I647987 of the Republic of China Announcement, an automatic film peeling machine for peeling films is provided, which mainly includes a conveying unit, a blocking unit, a clamping unit, and a clamping unit. unit, rolling unit, first blowing unit and stripping unit.
