Background
In the manufacturing process of the printed circuit board, before the substrate is exposed, 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 substrate is exposed, the film is stripped to expose the photoresist layer so as to carry out the subsequent developing and etching procedures. The conventional film peeling machine mainly conveys a thin plate such as the printed circuit board through a front conveying section, moves the thin plate to a rear conveying section along a conveying direction from front to rear, and gradually peels off the thin film with wrinkles at the front end edge of the thin plate through a set of adhesive wheels or a pulley set. In the conveying process of the thin plate, in order to effectively guide and prevent the plate body of the thin plate from deforming or the front end edge from upwarping, a plurality of driven rolling wheels are correspondingly arranged above a plurality of driving rollers which are horizontally arranged at intervals in the front conveying section, so that the thin plate is clamped between the driving rollers and the driven rolling wheels to prevent the thin plate from being bent and deformed and to drive the thin plate to smoothly move backwards so as to peel off the thin film.
However, in the actual process of peeling off the film, it is found that when the gap between the plurality of driving rollers and the plurality of driven rolling wheels is fixed, although the thin plate can be effectively clamped and smoothly moved backwards, with the refinement of the process, a printed circuit board with a thinner thickness is required, and when the thickness is thinner, the printed circuit board is more easily bent, so that, according to the arrangement mode of the fixed gap between the conventional driving rollers and the driven rolling wheels, the front end of the printed circuit board is easily pressed against the rolling wheels due to upward bending in the advancing process of the printed circuit board, and is bent due to instant pressing, thereby affecting the subsequent film peeling operation. Furthermore, the gaps between the driving rollers and the driven rollers are fixed, so that the roller can only be applied to thin plates with a fixed thickness range during operation. For thicker or thinner sheets outside the thickness range, the height of the rolling wheels must be manually adjusted to allow proper clearance between the driving roller and the driven rolling wheel.
