Film withdrawing device and manufacturing method of flexible printed circuit board

Abstract

The invention provides a film withdrawing device and a manufacturing method of a flexible printed circuit board. The provided film withdrawing device can take out a plurality of film like members at the same time without generating any deformation on the film like members. The film withdrawing device (10) comprises a first attracting member (30) that can attract and hold one edge of a film like member (S); a second attracting member (130) that can attract and hold the other edge of the film like member (S); a first elevating member (60) that can lift or lower the first attracting member (30);a second elevating member (160) that can lift or lower the second attracting member (130); and a control part (210) that controls the movement of the first attracting member (30) and the second attracting member (130). The control part (210) controls the first attracting member (30) and the second attracting member (130) to attract and hold the uppermost film like member (S1) of a laminate (PS) and then makes any one of the first attracting member (30) and the second attracting member (130) go up or down relative to the other.

Description

technical field [0001] The present invention relates to a film take-out device and a method for manufacturing a flexible printed circuit board. Background technique [0002] In the manufacturing process of the flexible printed wiring board, there is a process of taking out one film-shaped member from a site where a plurality of film-shaped members such as copper foils are stacked, and providing it to another processing site. There is an apparatus disclosed in Patent Document 1 as an apparatus for taking out such a film-like member used in the manufacture of a flexible printed wiring board. In the structure disclosed in Patent Document 1, as a mechanism for preventing two film-like members from being taken out at the same time, it is specifically as follows: in a stacked state of a plurality of film-like members, the film at the end of the stacking order is sucked by a vacuum chuck. After the film-like part in the upper position, the first air cylinder is operated to raise t...

AI Technical Summary

Problems solved by technology

Therefore, sometimes the film-shaped member is bent and twisted

In particular, copper foil is prone to deformation such as bending or creases. Therefore, if one side of the moving frame is raised while being pressed by a vacuum chuck, it will cause the above-mentioned distortion.

[0007] Such distortion is not ideal because it causes defects in the manufacture of flexible printed circuit boards.
