The mounting plate 22 facilitates the installation and fixing of the first motor 23.

[0026] The first motor 23 has a first swing rod 24 fixedly connected to its front output shaft. The back of the first swing rod 24 is slidably connected to the front end of the sliding block 25. The outer wall of the sliding block 25 is slidably connected to the limiting plate 26. The first laser rangefinder 27 is fixedly connected to the left end of the first mounting box 21.

[0030] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0031] Second, before coating, the coating device 1 starts the first motor 23, which drives the first swing rod 24 to swing. The first swing rod 24 drives the sliding block 25 to move to the left within the limiting plate 26. The sliding block 25 drives the L-shaped rod 28 to move to the left, and the L-shaped rod 28 drives the second laser rangefinder 29 to move to the left. The second laser rangefinder 29 detects the thickness of the polarizer before coating and transmits the electrical signal to an external display screen so that the operator can observe the thickness of the polarizer before coating. Then, the coating device 1 is started, and the polarizer is coated by the coating device 1. Then, the first motor 23 is started, which drives the first swing rod 24 to swing. The above steps are repeated to detect the coating thickness of the polarizer, so that the staff can detect abnormal coating thickness in time, prevent the production of unqualified products, reduce the generation of waste and production costs. When the sliding block 25 moves, the first laser rangefinder 27 is activated to detect the moving distance of the sliding block 25 and transmit the electrical signal to the external display screen. By judging the moving distance of the sliding block 25, the misjudgment phenomenon caused by excessive movement is prevented.

[0038] In this embodiment:

[0039] When dust removal is required on the polarizer, cylinder 31 is activated, which moves the protective net 32 ​​to the right, positioning it above the polarizer. Then, the second motor 35 is activated, driving the screw 36 to rotate. The screw 36 then moves the moving block 37 to the right, which in turn moves the second swing rod 38. The second swing rod 38 moves the sliding plate 310 via the protruding rod 39. Simultaneously, the second swing rod 38 moves the third swing rod 311, which in turn rotates the fixed rod 313.

This prevents uneven coating, bubbles, scratches, and other defects from occurring later, improving the optical performance and appearance quality of the polarizer.
