The film tearing device provided by the invention comprises a winding barrel 3, a film tearing mechanism 4, a material receiving mechanism 5 and a conveying mechanism 2. The winding drum 3 is used for releasing the adhesive tape, the film tearing mechanism 4 comprises a pressing roller 41 and a tearing-starting roller 42, the adhesive tape for sticking the protective film starts from the winding drum 3 and sequentially winds through the pressing roller 41, the tearing-starting roller 42 and finally enters the material receiving mechanism 5. In the film tearing process, under the transmission action of the conveying mechanism 2, workpieces sequentially pass through the space between the pressing roller 41 and the conveying mechanism 2 and the space between the tearing-starting roller 42 and the conveying mechanism 2; the pressing roller 41 is used for pressing the adhesive tape on the surface of the workpiece, so that the adhesive tape is attached to the surface of the workpiece, and further the adhesive tape is attached to the protective film on the surface of the workpiece; the function of the tearing roller 42 is to guide the adhesive tape adhered with the protective film away from the surface of the workpiece, so that the protective film is separated from the surface of the workpiece. In order to ensure good film tearing effect, the diameter of the tearing-starting roller 42 is required to be smaller than that of the pressing roller 41, because the smaller the diameter is, the larger the curvature of the roller wheel is, and the larger the bending degree is; in the pressing process, in order to ensure the tightness of the adhesion between the adhesive tape and the surface of the workpiece, the curvature of the pressing roller 41 should be small and the bending degree should be small. After the pressing process is completed, the protective film needs to be torn off the surface of the workpiece by using the adhesive tape, and the adhesive tape sequentially winds the pressing roller 41 and the tearing start roller 42, so that the diameter of the tearing start roller 42 is smaller than that of the pressing roller 41, the extending direction of the adhesive tape is matched with the curvature changing direction of the tearing start roller 42, and a good peeling effect can be achieved between the protective film and the workpiece. This is also because the work of the present invention is a glass substrate, which is thin and large in size, and if the turning angle of the tape is small, the glass substrate and the protective film are both taken off the surface of the conveying mechanism 2 by the tape. Therefore, in the invention, the diameter of the tearing-starting roller 42 is smaller than that of the pressing roller 41, so that the film tearing mechanism 4 can achieve a good film tearing effect, the rejection rate is low, and the working efficiency is high.
As an embodiment of the present invention, the pressing roller 41 may be arranged on the frame 1 in a liftable manner.

The setting of first inductor 45 can improve the accuracy and the validity of dyestripping device dyestripping, promptly, only when the inductor senses the existence of work piece, just can control stitching roller 41 and carry out the pressfitting process, and then carry out the dyestripping process, reduces the emergence of invalid action.
Preferably, the first sensor 45 can be connected with the material receiving mechanism 5 through a third control circuit, when the first sensor 45 senses that a workpiece is conveyed from the conveying mechanism 2, the first sensor 45 transmits a signal to the third control circuit, the material receiving mechanism 5 is controlled to start material receiving movement through the third control circuit, the adhesive tape is driven to move around each roller, and the adhesive tape is matched with the descending movement of the pressing roller 41 to start a film tearing process.
