This invention discloses a polarizer film tearing device, comprising a polarizer positioning unit, a corner lifting unit, and a film tearing power unit. On one hand, this invention utilizes the coordinated rotation and forward movement of the rubber roller. Through switching between first and second modes of the rotation power unit, the film corners are lifted in stages and aligned with the curved protruding surface. This facilitates clamping with the lifted corners flat, effectively reducing the probability of film folding or deformation, ensuring smooth film tearing, and minimizing polarizer pulling. On the other hand, the film tearing is performed by aligning the convex surface of the curved protrusion with the roller surface. This not only increases the lifting width of the film corners but also avoids the risk of breakage due to misalignment during clamping, significantly improving tearing quality and efficiency.
