Description

Film peeling module (1)

This creation is about a film stripping module, especially one that can effectively and comprehensively strip the film.

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, and after exposure, the film is peeled off to make the photoresist Layers are exposed for subsequent development and etching procedures. The way of peeling the film of the existing film peeling machine is mainly to transport the thin plate such as the above-mentioned printed circuit board through a front conveying section, so that it moves along the conveying direction from front to back, and the thin plate is blocked and positioned by a blocking unit. After a set of embossing wheels is rolled on the front edge surface of the film, the thin plate will continue to be conveyed backward along a rear conveying section, and the wrinkled film will be peeled off gradually by a set of sticking wheels.

With the above film stripping machine structure, the efficiency of stripping the film can indeed be improved. However, in the process of actually peeling off the film, it is found that when the thickness of the substrate itself is not large, especially for thin or flexible boards with a thickness of less than 0.1mm, or even 0.04mm, it is easy to have unevenness. When the long straight cylindrical adhesive roller with the same outer diameter sticks to the front edge of the film, since the adhesion force of each sticking position will not be exactly the same, that is, it is impossible to separate the front edge of the film from the substrate first, and then smoothly and effectively make the film comprehensive. and because the thickness of the film is very thin and fragile, after the film is peeled off, some film chips will still adhere to the surface of the photoresist layer, and cannot be detected because the area of the film chips is too small It is known that this kind of phenomenon will cause the substrate to be scrapped during the entire manufacturing process of the printed circuit board, and even damage the parts of the film stripping machine.

In view of this, in order to provide a structure different from the conventional technology and improve the above-mentioned shortcomings, the author has accumulated many years of experience and continuous research and development, so this creation is produced.
