Description

Floating roller structure

This creation is about a floating rolling wheel structure, especially a kind of rolling wheel that can be automatically raised or lowered to adjust the gap between the rolling wheel and the driving roller below it according to the thickness of the sheet that is clamped and passed through. By.

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 printed circuit boards and other thin plates, so as to move to a rear conveying section along the conveying direction from the front to the rear, and then use a set of The sticky pulley or the pulley set gradually peels off the wrinkled film at the front edge of the sheet. During the conveying process of the thin plate, in order to effectively guide and prevent the deformation of the plate body of the thin plate or the upward warping of the front edge of the thin plate, a plurality of driving rollers arranged at horizontal intervals in the front conveying section will be correspondingly arranged above a plurality of slave rollers. A moving rolling wheel is used to sandwich the sheet between a plurality of driving rollers and a plurality of driven rolling wheels to prevent the sheet from being flexed and deformed, and to drive the sheet to move backward smoothly to peel off the 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 rollers is fixed, although the thin plate can be effectively clamped and the thin plate can be moved smoothly backward, but with the The refinement of the process requires a printed circuit board with a thinner thickness. When the thickness is thinner, it is easier to cause the printed circuit board to flex. In this way, according to the fixed gap arrangement of the existing driving roller and the driven roller, during the advancement of the printed circuit board, the printed circuit board The front end is easily pressed against the rolling wheel due to upward bending, and is bent due to the instantaneous pressing, which affects the subsequent film peeling operation. Furthermore, the gaps between the plurality of driving rollers and the plurality of driven rollers are fixed, which can only be applied to thin plates with a fixed thickness range during operation. For thicker or thinner sheets beyond the thickness range, the height of the rolling wheel must be manually adjusted to make the gap between the driving roller and the driven rolling wheel appropriate.
