Description

Film debris removal structure

The invention relates to a film scrap removal structure, in particular to a method for effectively removing partially fragmented film fragments during film rolling of a stripper.

In the manufacturing process of the printed circuit board, before the exposure, the photoresist layer and the film adhered to the surface of the photoresist layer are respectively formed on the upper surface and the lower surface of the substrate. After the exposure, the film is peeled off to make the photoresist The layers are exposed for subsequent development and etching procedures. The conventional stripping machine peels the film mainly by means of a front conveying section for conveying the thin plate such as the printed circuit board, so as to move along the front-back conveying direction, and the thin plate is blocked by a blocking unit. After rolling on the surface of the film through a set of embossing wheels, the thin plate continues to be conveyed backwards after the conveying section, and the film which wrinkles the leading edge is gradually peeled off by a set of sticky wheels.

With the above stripping machine structure, the efficiency of the peeling film can be improved. However, during the actual rolling of the film, it was found that since the thickness of the film was thin and fragile, most of the wrinkle film remained intact when the embossing wheel was rolled, but a small portion of the film was broken. Cracking and letting the broken film fragments fly around, so when the stripping machine works in the clean room, not only may the film fragments reattach to the surface of the photoresist layer, leaving the substrate facing the end of life. As a result, it may also affect the operation of other machinery and the precision of other products.

The front end of the 12 is blown upward toward the rear end, whereby after the upper embossing wheel set 21 and the lower embossing wheel set 31 simultaneously press the film 122, the film 122 of the upper and lower surfaces of the thin plate 12 is respectively lifted rearward by the front end edge.

The present film debris removal structure 1 includes an upper cover 4, a lower cover 5, and an air extracting device 6. The upper cover 4 is a frame body having an open side and a bottom surface respectively, and the rear side of the upper cover 4 is fixed on the upper seat 2 to cover the embossing wheel set 21, and the upper cover 4 includes a front plate 41, a left side plate 42, and a front plate The right side plate 43 and the top plate 44 are provided with a suction hole 441 on the plate surface of the top plate 44, and the air suction hole 441 is connected to the air suction device 6. The lower cover 5 is a frame on which the rear side and the top surface respectively form an opening, and the rear side of the lower cover 5 is fixed on the lower seat 3 to cover the lower embossing wheel set 31. The lower cover 5 includes a front end plate 51 and a left end. The plate 52, a right end plate 53 and a bottom end plate 54 are provided with at least one air inlet hole 541 on the surface of the bottom end plate 54, and a rectangular space is formed between the upper cover 4 and the lower cover 5, thereby extracting the upper embossing wheel. The group 21 and the lower embossing wheel set 31 press the chips generated by the film 122 and are discharged outward through the air vent 441.
