Problems solved by technology

[0005] An object of the present invention is to provide a structure for removing film debris, which can solve the problem of partially fragmented film fragments flying around in the film rolling process of the existing film stripping machine, and can make the fragmented film fragments It can be effectively removed after rolling to avoid material waste caused by substrate scrapping; and when working in a clean room, it can prevent film fragments from flying around and affecting the movement of other machines and the precision of other products

Abstract

A film scrap removal structure is used for removing film scraps generated after a sheet on a stripping machine is rolled through a knurling wheel group. The knurling wheel group comprises upper and lower seats in vertical opposite arrangement, and an upper knurling wheel group and a lower knurling wheel group are arranged on one sides of front ends of the upper and lower seats and synchronously and horizontally move to roll front end edges of films on upper and lower surfaces of the sheet. An upper cover is fixed to the upper seat to cover the upper knurling wheel group, a lower cover is fixedto a lower seat to cover the lower knurling wheel group, and in operating of an air suction device, the film scraps can be driven to move outwards through an air suction hole in the top end of the upper cover.

Description

technical field [0001] The invention relates to a structure for removing film debris, in particular to a structure which can effectively remove partially broken film debris during the film rolling process of a film stripping machine. Background technique [0002] 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 layer exposed for subsequent developing and etching procedures. And the mode of peeling film of existing film stripping machine, mainly is to convey the above-mentioned thin plate such as printed circuit board through a front conveying section, make along the conveying direction from front to back, and the thin plate passes through the blocking positioning of a blocking unit, After rolling on the surface of the film by a set...
