Description

Film rolling device

This creation relates to a film rolling device of a film peeler, especially a type that can work through the cooperation of electric and pneumatic pushing mechanisms when processing thin plates of different thicknesses to increase film rolling efficiency and ensure processing quality.

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 formed on the upper and lower surfaces of the substrate. After the exposure, the film is peeled to make the photoresist. The layer is exposed for subsequent development and etching processes. The existing method of peeling the film by the peeling machine mainly uses a front conveying section to convey the thin plates such as the printed circuit board described above, so that the thin plates are moved in the conveying direction from front to back, and the thin plates are positioned by a blocking unit. After rolling on the surface of the film through the upper embossing wheel set and the lower embossing wheel set, the sheet will continue to be conveyed backward along a rear conveying section, and the film with wrinkles at the front edge will be gradually peeled off with a set of sticky wheels.

With the above peeling machine structure, the efficiency of the peeling film can be improved. In the process of rolling the film, the upper seat connected to the embossing wheel set is mainly driven by air pressure for the thin plate with a fixed thickness. Therefore, the upper embossing wheel set can be rolled on the surface of the film with elasticity, so that the front edge of the film is wrinkled, but the substrate surface is not damaged due to too rigid force.
