Film tearing device

The invention discloses a film tearing device which comprises a carrying mechanism, a feeding mechanism, a film sticking mechanism, a pressure maintaining mechanism, a clamping mechanism and a discharging mechanism. The carrying mechanism is used for bearing and driving a workpiece to pass through a feeding position, a film sticking position, a pressure maintaining position and a film tearing position; the feeding mechanism is arranged at the feeding position and used for placing the workpieces on the carrying mechanism. The film sticking mechanism is arranged at the film sticking position and used for sticking the film sticking piece to the film piece; the pressure maintaining mechanism is arranged at the pressure maintaining position and used for maintaining the pressure of the joint of the film part and the film sticking part on the workpiece; the clamping mechanism is arranged at the film tearing position and is used for clamping the film sticking piece; the discharging mechanism corresponds to the film t
