Problems solved by technology

[0004] The present invention aims to solve the problem that after the knurling of FPC, under the pressure of the knurling wheel in the rolling process, the release film in the filming area is still relatively close to the surface of the FPC. Static electricity is a technical problem that brings difficulties to the film tearing work. A film tearing device and its working method based on the knurling film-lifting mechanism are provided. Adhesive paper is used to increase the damage surface of the release film in the knurling film-lifting area. Adhesive area of ​​adhesive tape, improve adhesion to release film, good tearing effect

Abstract

The invention discloses film-tearing equipment based on a knurling film-removing mechanism and a working method thereof. By using glue paper and using the broken surface of a release film in a knurling film-removing area, the adhesive area of the adhesive paper is increased, the adhesion force to the release film is improved, and the film-tearing effect is good. The film-tearing equipment based onthe knurling film-removing mechanism includes a roller film-removing device and a propulsion device, and the roller film-removing device is installed on the propulsion device, the roller film-removing device is provided with a set of knurl wheels, and the set of the knurl wheels rolls over the release film during forward movement of the propulsion device in the X-axis direction; the roller film-removing device is installed at the movable end of a third power device, the fixed end of the third power device is installed at the movable end of the propulsion device, the fixed end of the propulsion device is installed on a shaping base, and a shaping platform is further arranged on the shaping base; and the shaping base and the film-tearing device are installed on a machine frame, the film-tearing device is provided with a power device moving up and down in the Z-axis direction, and adhesive paper is arranged at the moving end of the power device. The invention relates to the technical field of the film tearing of flexible printed circuit.

Description

technical field [0001] The invention relates to the technical field of film tearing of flexible circuit boards, in particular to a film tearing device based on a knurling film raising mechanism and a working method thereof. Background technique [0002] In the prior art, the flexible circuit board is referred to as FPC for short. FPC is the abbreviation of Flexible Printed Circuit in English. In the production of FPC, at least one side will use a release film to isolate and protect the surface of the board to prevent the board from being worn and dusty. situation occurs; the release film needs to be removed prior to subsequent development and etching. Among them, the removal of the release film generally requires two processes, one is to remove the film, so that part of the release film is separated from the FPC surface, destroying its electrostatic bonding, and facilitates the tearing action of the subsequent process; the other is to tear the film, using The external force...
