The limiting assembly plays a role in preventing the automatic film tearing mechanism from being damaged due to the fact that the transverse positioning assembly is out of order. The limiting piece 29 limits the moving range of the bearing plate 23, when the bearing plate 23 moves to the foremost end, the limiting baffle 20 at the front end of the bearing plate 23 will abut against the limiting piece 29 at the front end of the slide rail 21; when the receiving plate 23 moves to the rearmost end, the limit stop 20 at the rear end of the receiving plate 23 will abut against the limit stop 29 at the rear end of the slide rail 21.
Referring to fig. 1 to 3, further, the automatic film tearing mechanism further includes a lifting device, and the lifting device includes a lifting driver 31, a lifting ball nut 32 and a guiding assembly;
the fixed end of the lifting driver 31 is connected with the output end of the transverse moving device 2, the lifting ball nut 32 is arranged in the middle of the fixed plate 11, and the screw rod of the lifting driver 31 is in threaded connection with the lifting ball nut 32;
the guide assembly comprises a guide rod 33 and a movable piece 34, the movable piece 34 is arranged on the fixed plate 11, and the lower end of the guide rod 33 is connected with the output end of the transverse moving device 2; the upper end of the guide rod 33 passes through the movable member 34 and is slidably connected to the movable member 34.
The part glues the double faced adhesive tape on the product surface viscosity height, relies on clamping jaw 133 centre gripping hand to tear the piece and drives from type membrane rotation, is difficult to tear out from type membrane from the product surface. Therefore, when the clamping jaw 133 moves forwards and rotates forwards, the lifting driver 31 drives the clamping jaw 133 to lift upwards, so that the action that the hand lifts upwards when tearing the release film of the double-sided adhesive tape with higher viscosity is simulated by the hand, and the automatic film tearing mechanism can tear the release films of the double-sided adhesive tapes with various viscosities.
The lifting driver 31 is a driving device for converting a rotational motion into a linear motion, and may be a screw stepping motor. Since the lifting driver 31 is a precision mechanism and the film tearing device 1 has a certain weight, the film tearing device 1 may be deflected during the lifting process. Therefore, a guide structure is arranged, the guide structure plays a role in guiding, and the film tearing device 1 can be prevented from shifting in the lifting process.
Furthermore, the lifting device further comprises a height limiting assembly, wherein the height limiting assembly comprises a connecting bracket 35, a high-position sensor 36, a low-position sensor 37, a high-position baffle 38 and a low-position baffle 39;

The height limiting component plays a role in limiting the height of the position of the film tearing device 1 and prevents the fixed plate 11 from moving beyond the moving range to cause damage to the film tearing device 1. When the lifting device drives the fixing plate 11 to move, if the fixing plate 11 moves to the lowest point of the moving range, the low-level baffle 39 will shield the sensing end of the low-level sensor 37, and the low-level sensor 37 controls the lifting driver 31 through an electric signal to prevent the fixing plate 11 from continuously moving downwards; if the fixed plate 11 moves to the highest point of the movable range, the high-position baffle 38 will block the sensing end of the high-position sensor 36, and the high-position sensor 36 controls the lifting driver 31 through an electric signal, so as to avoid the problem that the movable member 34 is separated from the guide rod 33 because the fixed plate 11 continues to move upwards, and prevent the film tearing device 1 from being damaged.
