[0028] A positioning plate 11, the positioning plate 11 is fixedly arranged on the lower outer wall of the side of the clamping plate 10, a limiting frame 12 is fixedly connected to the outer wall of the side of the positioning plate 11, a knob 13 is movably connected to the outer wall of the side of the limiting frame 12, a transmission frame 14 is sleeved on the outer wall of the knob 13, an end of the transmission frame 14 is fixedly connected to a clamping block 15, and a limiting roller 16 is installed on the inner wall of the limiting frame 12 on the side of the clamping block 15. The limiting frame 12 and the knob 13 form a rotating structure, which is convenient for the user to rotate the knob 13.

[0029] In one of the embodiments, the limiting mechanism 5 includes a sleeve 501 and a movable vacuum chuck 502, and the sleeve 501 is sleeved on the outer wall of the transmission rod 4, and a movable vacuum chuck 502 is fixedly connected to the upper surface of the sleeve 501, which is convenient for the limiting mechanism 5 to move when the transmission rod 4 rotates, so as to facilitate the device to process polarizers with different lengths fixed thereon.

[0030] In one embodiment, the sleeve 501 is threadedly connected to the transmission rod 4, and the movable vacuum chuck 502 is slidably arranged on the base 1, and the upper surfaces of the movable vacuum chuck 502 and the fixed vacuum chuck 2 are on the same horizontal plane, which facilitates the rotation of the sleeve 501 with the transmission rod 4 to drive the movable vacuum chuck 502 to slide relative to the base 1, thereby adjusting the distance between the movable vacuum chuck 502 and the fixed vacuum chuck 2, and facilitating the stable fixation of the polarizer on the device for processing.

[0034] The working principle of the present utility model is as follows: When using the film tearing device for the polarizer, first as Figures 1-2 shown, the user adjusts the device according to the length of the polarizer. At this time, the user starts the adjustment servo motor 3, and then the adjustment servo motor 3 drives the transmission rod 4 to rotate. Next, the sleeve 501 moves along the transmission rod 4, and as the sleeve 501 moves, the sleeve 501 drives the movable vacuum chuck 502 to slide relative to the base 1, thereby adjusting the distance between the movable vacuum chuck 502 and the fixed vacuum chuck 2.

Therefore, the device is convenient for fixing polarizers of different lengths, thereby facilitating the film tearing processing of polarizers of different lengths by the device, improving the versatility of the device. Then as Figures 1-4As shown, the user tears a corner of the film on the polarizer and winds the torn corner of the film around the limiting roller 16. Then the user rotates the knob 13. Next, the transmission frame 14 moves relative to the limiting frame 12 along the knob 13. Subsequently, the transmission frame 14 drives the clamping block 15 to move. And with the continuous movement of the clamping block 15, finally the clamping block 15 fits the film on the limiting roller 16, so as to stably limit a corner of the film through the limiting roller 16 and the clamping block 15. Then the user starts the film tearing servo motor 7. Next, the film tearing servo motor 7 drives the driving rod 8 to rotate. Then the sleeve 9 moves along the driving rod 8 and the sleeve 9 drives the clamping plate 10 to slide relative to the bracket 6. Subsequently, the sleeve 9 drives the positioning plate 11 to move so that the limiting frame 12 moves. At this time, the limiting frame 12 drives a corner of the film to continuously move, thereby tearing the film on the polarizer.
