Description

Protective film uncovering process based on lifting angle and rolling cooperative screen display glass Technical Field The invention belongs to the technical field of screen display, and particularly relates to a protection film uncovering process based on lifting angle and rolling cooperative screen display glass. Background A screen display (display screen) is generally composed of a plurality of functional layers and a liquid crystal display panel, wherein the liquid crystal display panel performs assembly of other components based on glass as a carrier, that is, the glass needs to be subjected to protective film peeling before assembly. At present, the step of removing the glass protective film is specifically as follows: S1, lifting angle The film tearing adhesive tape is adhered to one corner of the glass protective film, and then the film tearing clamping jaw is used for clamping the film tearing adhesive tape to move relative to the glass, so that the film tearing adhesive tape drives the protective film to tilt from the corner to form a lifting angle; S2, tearing off Then gradually tearing the protective film away from the surface of the glass based on the diagonal movement of the film tearing clamping jaw relatively far away from the glass and towards the corner; s3, film collection Adopt receipts membrane clamping jaw motion and centre gripping protection film, simultaneously based on receipts membrane clamping jaw and tear cooperation of membrane clamping jaw in order to break away from the tear film clamping jaw with the tear film sticky tape, by the unclamping of receipts membrane clamping jaw simultaneously, will take off the protection film of separating and drop to receipts membrane material frame. However, in the process of peeling off the protective film, there are the following technical drawbacks: 1) In the initial lifting angle process, acting force is concentrated on the film tearing adhesive tape, when the interfacial adhesion force between the adhesive tape and the protective film is smaller than the peeling force required by lifting angle, peeling failure is easy to occur between the adhesive tape and the protective film, and interfacial separation is not performed between the protective film and the glass substrate, so that an effective lifting angle cannot be formed as a result, the adhesive tape is more directly caused to fall off, and the lifting angle forming success rate of the working procedure in the initial stage is lower; 2) In the tearing step, the glass is in a static state, the tearing process is a simple single-point and unidirectional stretching process, the tearing angle and the tearing force cannot be adjusted, so that the tearing force direction and the tearing force cannot be controlled, stress concentration is easily formed in the protective film, and tearing occurs when the tearing force exceeds the cohesive strength of the protective film; 3) Because the dyestripping sticky tape can produce deformation and more coincide and attach on the dyestripping clamping jaw in driving the dyestripping in-process, in case receive the collaborative power that the clamp jaw formed and break away from the dyestripping clamping jaw with the dyestripping sticky tape, lead to the dyestripping sticky tape to break away from the protection film and attach on the dyestripping clamping jaw, and the dyestripping clamping jaw that has the dyestripping sticky tape directly influences the continuity that the protection film of next glass was uncovered. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide an improved protective film uncovering process based on lifting angles and rolling cooperative screen display glass. In order to achieve the above purpose, the invention adopts the following scheme: a protection film uncovering process based on lifting angle and rolling cooperative screen display glass comprises the following steps: S1, lifting angle Firstly, the screen display glass is horizontally arranged downwards from a film to be torn, a part of the film tearing adhesive tape is clamped by a film tearing clamping jaw, the rest of the film tearing adhesive tape is partially exposed and is adhered to one corner of the protective film from the adhesive surface upwards, wherein the film tearing adhesive tape is divided into an adhesion section, a connection section and a clamping section; S2, tearing off Based on the opposite movement cooperation of the screen display glass and the film tearing clamping jaw, the film tearing clamping jaw moves diagonally from the corner to the corner, so that the tearing angle is kept unchanged or gradually reduced; the screen display glass moves along the length and/or width direction of the screen display glass; s3, film collection In the cooperation of tearing film pulling based on film collecting clamping jaw and tearing film clamping jaw and blowing based on the air flow formed in the opening of the tea
