Description

Low-damage lifting angle and motion tearing-off cooperative film tearing process of screen display glass protective film Technical Field The invention belongs to the technical field of screen display, and particularly relates to a low-damage lifting angle and movement tearing-off cooperative film tearing process of a screen display glass protective film. Background A screen display (display screen) is generally composed of a plurality of functional layers and a liquid crystal display panel, in which the liquid crystal display panel is assembled with other components based on glass as a carrier, that is, the glass needs to be peeled off with protective films (front and back) before assembly. At present, for the peeling off of the single-sided protection film, the following steps are adopted: 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, based on the inversion of the screen display glass, the film tearing of the front and back protective films is completed in sequence, and therefore, the film tearing process has the following technical defects: 1) For a single-sided film tearing, when the interfacial adhesion between the film tearing adhesive tape and the protective film is smaller than the peeling force required by a lifting angle in the process of forming the tearing angle, the breaking or failure rate of the lifting angle of the protective film can be increased, and the difficulty and loss of the film tearing are increased due to the fact that the film tearing adhesive tape is broken or broken accidentally; 2) For the film tearing reversing, the adopted glass is turned over, so that not only is the accidental rubbing rate of the glass increased, but also the turning over requires a movement space and a corresponding equipment structure, so that the film tearing equipment is complex in structure, large in occupied space and unfavorable for transmission. Disclosure of Invention The invention aims to overcome the defects of the prior art and provide an improved low-damage lifting angle and movement tearing-off cooperative film tearing process for a screen display glass protective film. In order to achieve the aim, the invention adopts the scheme that the low-damage lifting angle and movement tearing-off cooperative film tearing process of the screen display glass protective film comprises the following steps of: s1, tearing films on the surface A, wherein the adopted film tearing structure on the surface A sequentially lifts corners and tears away; s2, screen display glass transshipment; S3, tearing off the B surface by adopting a B surface tearing film structure, particularly, In the lifting angle of the step S1, firstly, sucking reversely by adopting an adsorption platform, enabling the A mask to face downwards and transferring the A mask to a film tearing area of the A mask, attaching a film tearing adhesive tape to the corner of the A mask from an adhesive section, and simultaneously enabling the film tearing adhesive tape to extend from the corner to form an extension section; secondly, clamping the tail end of the epitaxial section by using a film tearing clamping jaw, wherein the epitaxial section is divided into a clamping part and a connecting part, simultaneously the film tearing clamping jaw turns inwards to gradually enlarge the angle between the connecting part and the screen display glass, and rolling the film tearing clamping jaw at an adhesive section by using a roller to finish film tearing preparation; finally, under the inward turning and inward moving of the film tearing clamping jaw, the roller synchronously shifts along with the film tearing clamping jaw and moves upwards in a jacking mode so as to keep the same gradual inward turning of the rolling abutting position of the roller and the inward turning tearing position of the corner, meanwhile, the film tearing clamping jaw is blown to the screen display glass along the connecting part and is refracted to the position between the A mask and the screen display glass to cooperatively t
