Automatic film tearing mechanism for FPC (Flexible Printed Circuit) protective film

Abstract

The invention provides an automatic film tearing mechanism for an FPC (Flexible Printed Circuit) protective film, which is used for separating backing paper on the FPC protective film and comprises a film feeding mechanism, a double-sided overturning film tearing platform, a backing paper pulling mechanism and a film transfer platform which are arranged in sequence, and the film feeding mechanism comprises a suction plate and feeds a film material to the double-sided overturning film tearing platform; the double-sided overturning film tearing platform comprises a first platform, a second platform, a first driving mechanism, a film sticking roller and a first vacuum mechanism arranged between the first platform and the second platform, the suction plate adsorbs backing paper, the first driving mechanism drives the film sticking roller to do reciprocating motion, a film is rolled on the film sticking roller, and the first vacuum mechanism is arranged between the first platform and the second platform. One corner of the backing paper is separated; the automatic film tearing machine has the advantages that the machine automatically completes the film tearing process, the labor cost is saved, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic tearing of protective film, in particular to an automatic tearing mechanism of FPC protective film. Background technique [0002] Flexible printed circuit (Flexible Printed Circuit, FPC), also known as flexible circuit board, flexible circuit board, is favored for its light weight, thin thickness, free bending and folding and other excellent characteristics. With the rapid development of the electronics industry, the design of circuit boards is becoming more and more high-precision and high-density, and the development of the FPC industry has become an inevitable trend. In the FPC flexible circuit board industry, the FPC needs to be covered with a layer of FPC protective film. The main functions of the protective film are: 1. To protect the copper foil from being exposed to the air and avoid the oxidation of the copper foil; 2. To carry out the subsequent surface treatment. Covering; 3. In the ...

AI Technical Summary

Problems solved by technology

However, most domestic fpc manufacturers are relatively small in scale, and the number of single products produced per day is relatively small (dozens to hundreds of sheets). Using roll film will cause cost waste, so these factories give priority to single-sheet, die-cut protective film , by manually tearing the film and pasting it on the copper foil

Few of the existing equipment have automatic single-sheet protective film tearing, and manual completion has the problems of low labor efficiency and high production costs. It is urgent to study an equipment that can complete single-sheet protective film tearing to solve the existing problems. The problem
