The inner ring of the bearing 16 is fixedly sleeved on the first slide 15. The first slide 15 is slidably sleeved on the guide rod 19. A second slide 17 is slidably sleeved on the guide rod 19 between the two first slides 15. The two second slides 17 are divided into The guide rod 19 is fixed on the left and right ends of the thin plate 5, and a limit plate 18 is fixed on the guide rod 19. The limit plate 18 is located below the thin plate 5. A plurality of fan fixing mechanisms 2 are installed on the top surface of the wind guide plate 3 below. A scale line 20 is provided on the top of the guide rod 19, and the scale line 20 is located above the limit plate 18. The left and right ends of the top surface of the thin plate 5 are threadedly connected with the first limit screw 13. The top of the first limit screw 13 is fixed with a limit block 4, and the first limit screw 13 is sleeved with a pressure plate 14.

[0025] The fan fixing mechanism 2 includes a bracket 205, which is fixedly connected to the air guide plate 3. An air guide duct 204 is fixedly arranged on the top of the bracket 205. The air guide duct 204 is located on the front side of the thin plate 5. The air guide duct 204 is located between the two air guide plates 3. A second splint 202 is fixedly arranged on both sides of the air guide duct 204. A second limiting screw 203 is threadedly connected to the second splint 202. The two second limiting screws 203 are fixedly arranged on one end close to each other with a first splint 201.

[0026] Working principle: Place the optical film on the top surface of the thin plate 5, then rotate the first limiting screw 13 so that the limiting block 4 presses the edge of the optical film through the pressure plate 14, then insert the air outlet end of the fan into the air duct 204, rotate the second limiting screw 203, so that the two first clamping plates 201 are close to each other to clamp the fan and fix the fan. For the optical film with bulging top surface, the optical film and the thin plate 5 are combined into a wing-like structure, and then use the fan to blow air to the optical film to make the optical film and the thin plate 5 rise, so as to judge whether the surface of the optical film is bulging based on whether the optical film and the thin plate 5 rise.

[0027] Example 2

[0028] like Figure 1As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: multiple motors 12 are fixed on the left and right sides of the base 1, the power output end of the motor 12 is fixedly connected to the support plate 10, and the top surface of the support plate 10 is connected to the counterweight 7 through multiple springs 9.
