Description

Film stripping module

Technical Field

The present invention relates to a film peeling module, and more particularly to a film peeling module capable of peeling a film effectively and comprehensively.

Background

In the manufacturing process of the printed circuit board, before the exposure of the substrate, a photoresist layer and a film adhered to the surface of the photoresist layer are respectively formed on the upper surface and the lower surface of the substrate, and after the exposure, the film is stripped to expose the photoresist layer so as to carry out the subsequent developing and etching procedures. The conventional way of peeling the film from the film peeling machine is to transport the thin plate such as the printed circuit board or the like through a front transport section, move the thin plate along the transport direction from front to back, position the thin plate by a blocking unit, roll the thin plate on the front end edge surface of the thin film through a set of embossing wheels, then transport the thin plate continuously along a back transport section to back, and peel off the wrinkled thin film gradually through a set of adhesive wheels.

By the structure of the film stripping machine, the efficiency of stripping the film can be improved really. However, in the actual peeling process of the film, it is found that when the thickness of the substrate itself is not large, especially for the thin plate or soft plate with the thickness below 0.1mm, even 0.04mm, the bending phenomenon is easy to occur. When the long straight cylinder-shaped adhesive wheel with the same outer diameter adheres the front end edge of the film, the adhesive force of each adhering position is not completely the same, namely the front end edge of the film cannot be separated from the substrate firstly, and then the film can be peeled off comprehensively smoothly and effectively; moreover, since the film is thin and fragile, after the film is peeled off, a part of the film chip still adheres to the surface of the photoresist layer, and the area of the film chip is too small to be detected, which will cause the substrate to be scrapped and even cause the parts of the film peeling machine to be damaged in the whole manufacturing process of the printed circuit board.
