The bottom of the electric telescopic rod 11 is fixedly connected to the top of the fixed block 13, the bottom of the fixed block 13 is fixedly connected to the top of the fixed pipe 14, the bottom of the fixed pipe 14 is fixedly connected to the suction cup 13, and the fixed pipe 14 is connected to the air suction pipe 15.

[0024] In this embodiment, the electric telescopic rod 11 can drive the fixed block 12 to move when it is extended, the fixed block 12 drives the fixed tube 14 to move, and the fixed tube 14 drives the suction cup 13 to move. When the electric telescopic rod 11 is extended, it drives the fixed block 11, the fixed tube 14 and the suction cup 13 to descend, and when the suction pipe 15 extracts air from the fixed tube 14, the suction cup 14 absorbs the polarizer and grabs the polarizer.

[0025] The reverse thrust assembly 2 includes a support plate 21 , an air blowing pipe 22 and a branch pipe 23 . The air blowing pipe 22 is connected to one end of the branch pipe 23 , and the other end of the branch pipe 23 is fixedly connected to a through hole 211 on the support plate 21 .

[0026] In the present embodiment, preferably, the support plate 21 is placed on a workbench, and during the process of sucking the polarizer by the suction cup 14, the air in the blowing pipe 22 enters the branch pipe 23 and is sprayed from the branch pipe 23 to the bottom of the polarizer, thereby avoiding close contact between the lower surface of the polarizer and the support plate 21, and allowing air to enter between the polarizer and the support plate 21, making it easier for the suction cup 14 to grab the polarizer and avoiding grabbing failure. Embodiment 2

[0027] Reference Figures 1 to 6 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that.

[0028] It also includes a support assembly 3, which includes a slide groove 31 and a movable rod 32. The movable rod 32 is fixedly connected to the top of the electric telescopic rod 11, and both ends of the movable rod 32 are slidably connected to the inner wall of the slide groove 31.

[0029] In the present embodiment, preferably, the slide groove 31 is fixed by the existing support frame during installation, the slide groove 31 can support the movable rod 32, so that the movable rod 32 maintains a certain height, and the movable rod 32 can slide on the inner wall of the slide groove 31. When the movable rod 32 moves, it can drive the electric telescopic rod 11 to move, and the electric telescopic rod 11 drives the fixed block 11, the fixed tube 14 and the suction cup 13, as well as the polarizer adsorbed on the suction cup 13 to move.

[0030] The two sides of the fixed block 12 are fixedly connected to the fixed rails 121 , and the fixed rails 121 are slidably connected to the sliding sleeves 122 . The suction cups 13 and the fixed tubes 14 are provided in plurality, and the bottom of the sliding sleeves 122 is fixedly connected to the fixed tubes 14 .

[0031] Preferably in this embodiment, the sliding sleeve 122 can slide on the fixed sliding rail 121, and a fixed tube 14 is fixedly connected under each sliding sleeve 122. The fixed tube 14 is fixedly connected to the suction cup 13, and the fixed tube 14 is connected to the suction pipe 15. By setting a plurality of suction cups 13 and fixed tubes 14, a plurality of polarizers can be adsorbed and grasped at the same time, which is conducive to improving efficiency.

[0032] When the sliding sleeve 122 slides on the fixed sliding rail 121, the distance between each suction cup 13 can be adjusted to facilitate adaptation to different types of polarizers. The distance between the center points of a large polarizer is farther than that of a small polarizer, so the distance between each suction cup 13 needs to be adjusted.

[0033] Reference Figure 4 The sliding sleeve 122 is provided with a screw hole 123 , and the screw hole 123 is threadedly connected with a bolt 124 .

[0034] Preferably, in this embodiment, when the bolt 124 is tightened, the end of the bolt 124 is pressed against the upper surface of the fixed slide rail 121 , so as to fix the position of the slide sleeve 122 and prevent the slide sleeve 122 from moving after the position is adjusted.

[0035] It also includes a driving component 4 , which includes an air pump 41 . The air pump 41 has an air inlet end 42 and an air outlet end 43 . The air inlet end 42 is connected to the air suction pipe 15 , and the air outlet end 43 is connected to the air blowing pipe 22 .

[0036] In this embodiment, the air inlet end 42 of the air pump 41 is preferably used to suck air, and the air outlet end 43 of the air pump is used to blow out air. The air pump 41 can provide negative pressure for the air intake pipe 15 to extract the air inside the air intake pipe 15. The air is blown out to the air outlet end 43 by the air pump 41, and the air at the air outlet end 43 enters the blowing pipe 22. The air in the blowing pipe 22 enters the branch pipe 23 and is sprayed from the branch pipe 23 to the bottom of the polarizer, so as to avoid close contact between the lower surface of the polarizer and the support plate 21, so that air enters between the polarizer and the support plate 21, so as to facilitate the suction cup 14 to grab the polarizer and avoid grabbing failure.

[0037] The air outlet end 43 is provided with an air outlet hole 431 .

[0038] In this embodiment, it is preferred to prevent excessive air from entering the air blowing pipe 22, which would cause the air to blow the polarizer and cause the polarizer to bump.

[0039] Reference Figure 4 The blowing pipe 22 is fixedly connected to the fixed cylinder 221, and the inner wall of the fixed cylinder 221 is slidably connected to the piston column 222.

[0040] In this embodiment, preferably, the piston rod 222 can slide on the inner wall of the fixed cylinder 221. Figure 5 When the piston rod 222 moves to the top of the fixed cylinder 221, the air blowing tube 22 is opened and air can be blown out.

[0041] The top of the fixed cylinder 221 is connected to the telescopic rod 224 through the connecting tube 223 . The top of the telescopic rod 224 is fixedly connected to the movable rod 32 , and the bottom of the telescopic rod 224 is fixedly connected to the fixed slide rail 121 .

[0042] When the polarizer is adsorbed and grasped, the electric telescopic rod 11 is controlled to extend, and the electric telescopic rod is controlled to drive the fixed block 11, the fixed tube 14 and the suction cup 13 to descend, the fixed block 11 drives the fixed slide rail 121 to descend, the fixed slide rail 121 stretches the telescopic rod 224, the air pressure inside the telescopic rod 224 becomes smaller, and the inside of the telescopic rod 224 is connected to the top of the fixed cylinder 221 through the connecting tube 223. At this time, the piston column 222 is driven to move to the top of the fixed cylinder 221 under the action of air pressure. At this time, the blowing pipe 22 is opened and air can be blown out. When the suction cup 13 moves to the position of the polarizer, the air in the blowing pipe 22 enters the branch pipe 23 and is sprayed from the branch pipe 23 to the bottom of the polarizer, so as to avoid close contact between the lower surface of the polarizer and the support plate 21, so that air enters between the polarizer and the support plate 21, so as to facilitate the suction cup 14 to grasp the polarizer and avoid grasping failure.

[0043] After the polarizer is grabbed, the electric telescopic rod 11 contracts, driving the fixed block 11, the fixed tube 14 and the suction cup 13 to rise, the fixed block 11 drives the fixed slide rail 121 to rise, the fixed slide rail 121 compresses the telescopic rod 224, the air pressure inside the telescopic rod 224 reaches, the inside of the telescopic rod 224 is connected to the top of the fixed cylinder 221 through the connecting tube 223, and the piston rod 222 is moved to the top under the action of the air pressure. Figure 5 In the middle position, the piston column 222 closes the air blowing tube 22, and no air can be blown out. At this time, it is convenient to place a new polarizer on the support plate 21, and there is no need to perform additional control on the opening and closing of the air blowing tube 22, which is convenient to use. Push the movable rod 32 to move toward the automatic inspection machine until the polarizer is placed in the inspection area of ​​the automatic inspection machine, and then the polarizer can be inspected by the automatic inspection machine.

[0044] The support plate 21 is provided with a placement groove 212 .

[0045] In this embodiment, the polarizer is preferably placed in the placement groove 212 to prevent the polarizer from sliding on the support plate 21, resulting in the suction cup 14 not being aligned with the center point of the polarizer, resulting in a grasping failure.
