The invention relates to a protective film uncovering process based on corner lifting and rolling cooperation type screen display glass. The protective film uncovering process comprises the following steps: S1, corner lifting; s2, tearing off; and S3, collecting the film. On one hand, through cooperation of the film tearing clamping jaw and the rolling wheel, step-by-step peeling with the rolling position and the peeling position aligned is kept, meanwhile, the angle between the connecting section and the screen display glass is gradually increased on the basis that the connecting section is turned inwards under the condition that the adhesion section is not stressed, the success rate of forming an inwards-turned peeling angle is greatly increased, and the production efficiency is improved. The probability that the film-tearing adhesive tape is separated from the protective film or the corner of the protective film is torn is reduced; on the other hand, the complete tearing rate of the protective film is increased based on the relative movement of the glass and the film tearing clamping jaw, the tearing risk of the protective film is reduced, more labor-saving and faster diagonal tearing is achieved, meanwhile, based on pulling formed by the film collecting clamping jaw and the film tearing clamping jaw and airflow blowing cooperation formed by the film collecting clamping jaw and the film tearing clamping jaw, the completeness of film collecting is improved, and the production efficiency is improved. And the problem that the film tearing adhesive tape is adhered to the film tearing clamping jaw is solved, so that the continuity of peeling off the protective film is improved.
