Description

Screen display glass film tearing equipment Technical Field The invention belongs to the technical field of screen display glass treatment, and particularly relates to screen display glass film tearing equipment. Background A screen (display screen) is generally composed of a plurality of functional layers and a liquid crystal display panel, wherein the liquid crystal display panel is assembled with other components based on screen glass as a carrier, that is, the screen glass needs to be subjected to protective film tearing before assembly. At present, the step of uncovering the screen display glass protective film is specifically as follows: S1, lifting angle The method comprises the steps that a film tearing adhesive tape is adhered to one corner of a protective film of screen display glass, and then a film tearing clamping jaw is used for clamping the film tearing adhesive tape to move relative to the screen display 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 screen display glass based on the diagonal movement of the film tearing clamping jaw relatively away from the screen display 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 flip 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 flip 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 screen display glass substrate, so that an effective flip angle cannot be formed as a result, the adhesive tape is more directly caused to fall off, and the flip angle success rate of the process in the initial stage is lower; 2) In the tearing step, the screen display glass is in a static state, the tearing process is a simple stretching process with single point and one way, 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, when the tearing force exceeds the cohesive strength of the protective film, tearing occurs, or when the acting force direction deviates from the optimal tearing angle, the effective peeling force is insufficient, the tearing is interrupted, meanwhile, once local uneven adhesion or wrinkles occur, the static screen display glass cannot be adjusted in a matching way, all error correction only depends on clamping jaws, and the difficulty and the interruption risk of stable and continuous tearing are greatly increased.
