Description

Partial film peeling structure (2)

This creation is related to a part of the film peeling structure, especially one that can peel off the front edge of the film smoothly and effectively.

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. However, the existing method of peeling the film by the peeling machine mainly uses a front conveying section to convey the above-mentioned sheets such as printed circuit boards, so as to move along the conveying direction from front to back, and the sheets are blocked and positioned by a blocking unit. After rolling on the surface of the film through a set of embossing wheels, the sheet will continue to be conveyed backward along a rear conveying section, and a set of sticky wheels will gradually peel off the wrinkled film at the front edge.

With the above-mentioned structure of the peeling machine, the efficiency of peeling the film can indeed be improved. However, in the actual process of peeling off the film, it is found that because the thickness of the substrate itself is not large, it is easy to bend unevenly. When the long straight cylindrical adhesive wheel with the same outer diameter adheres the film, the adhesive force of each adhesive position will not be completely. Similarly, it is often impossible to gradually peel off the film smoothly and comprehensively; 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 often due to the thin film The area of the chip is too small to be detected, and this phenomenon will result in the substrate being scrapped throughout the PCB manufacturing process. Therefore, at present, different models are used to separate the front edge of the film and the subsequent complete film peeling, so as to make the construction more professional through an effective division of labor, thereby improving the output quality of the film peeling operation.

The wrinkled film is gradually peeled off, and due to the different adhesive force of each position of the adhesive film of the straight-shaped sticky wheel, the front edge of the film cannot be peeled off smoothly, and at least one film peeling unit can be provided on a frame. At least one hook on at least one film peeling unit presses against the surface of the substrate, thereby peeling off the structure of the front edge of the film, so that the front edge of the film can be separated from the substrate smoothly and effectively, so as to facilitate the subsequent overall film peeling operation.
