The setting of the guide plate 71 facilitates the collection of polarizers that have completed the inspection.

[0035] A loading structure 2 is provided on the top of the placement table 1, and the loading structure 2 includes a fixed seat 21 fixedly connected to the front and rear ends of both sides of the top of the placement table 1, and a rotating roller is rotatably connected between the fixed seats 21. The fixed seat 21 on the rear end side of the top of the placement table 1 is fixedly installed with a motor 22, and the output end of the motor 22 is fixedly connected to the rotating roller. A conveyor belt 23 is fixedly sleeved on the outer side of the rotating roller. The motor 22 is used to drive the rotating roller to rotate, and the rotating roller drives the conveyor belt 23 to rotate. Then, the staff only needs to place the polarizer on one side of the conveyor belt 23 in turn, and the conveyor belt 23 will automatically transport and load the polarizer.

[0036] A detection structure 3 is provided on the front and rear sides of the feeding structure 2. The detection structure 3 includes a cylinder 31 fixedly connected to the four corners of the bottom inner wall of the groove 11. The top of the output end of the cylinder 31 is fixedly connected to a mounting plate 32. The top of the mounting plate 32 close to the conveyor belt 23 is fixedly connected to a fixing block. A light source outlet 33 is provided on the fixing block at the front end of the placing table 1, and a light source receiving port 34 is provided on the fixing block at the rear end of the placing table 1. An infrared light emitter 35 is fixedly installed on the front end of the top of the mounting plate 32 at the front end of the placing table 1, and an infrared light receiver 36 is fixedly installed on the rear end of the top of the mounting plate 32 at the rear end of the placing table 1. An alarm 37 is provided on the top of the infrared light receiver 36, wherein the infrared light emitter 35, the infrared light receiver 36 and the alarm 37 are all existing products on the market, and their connection methods and control methods are all existing technologies. No further details are given, and the alarm 37 is electrically connected to the controller 6. When in use, by using tools such as a steel ruler, according to the warping standard of the polarizer, the cylinder 31 is used to drive the mounting plate 32 up and down, thereby adjusting the distance between the light emitted by the infrared light emitter 35 and the upper surface of the conveyor belt 23. The light emitted by the infrared light emitter 35 will first pass through the light source emission port 33 and then through the light source receiving port 34 to be received by the infrared light receiver 36, and judge whether the warping of the polarizer exceeds the standard based on the received light source. If the infrared light received by the infrared light receiver 36 is 100%, it means that the warping is within the standard and the polarizer meets the requirements. When the infrared light receiver 36 cannot receive 100% of the light from the emission source, it means that the warping of the polarizer exceeds the standard and needs to be picked out. The alarm 37 transmits an alarm signal to the controller 6.

[0037] A moving structure 4 is provided on the top of the detection structure 3. The moving structure 4 includes a vertical rod 41 fixedly connected to one side of the top of the fixed block, a horizontal rod 42 fixedly connected to one side of the top of the vertical rod 41, a slide groove 43 is provided on one side of the horizontal rod 42, and screws 44 are rotatably connected to the front and rear sides of the inner wall of the slide groove 43. A motor 2 45 is fixedly installed on the front end of the horizontal rod 42, and the output end of the motor 2 45 is fixedly connected to the screw 44. The screw 44 is threadedly connected to the moving block 46. The motor 2 45 is used to drive the screw 44 to rotate, thereby driving the moving block 46 to move back and forth in the slide groove 43.

[0038] The mobile structure 4 is provided with a sorting structure 5, which includes an electric telescopic rod 51 fixedly connected to one side of the mobile block 46. The bottom of the output end of the electric telescopic rod 51 is fixedly connected to a connecting block 52. The connecting block 52 is a hollow structure. The four corners of the bottom of the connecting block 52 are fixedly connected to connecting pipes 53. The bottom of the connecting pipe 53 is connected to a suction cup 54. An air pump 55 is fixedly installed on the top of the mobile block 46. The air inlet of the air pump 55 is fixedly connected to an air extraction pipe 56. One end of the air extraction pipe 56 is connected to the inside of the connecting block 52, and the air extraction pipe 56 is connected to an air inlet pipe 57. An electromagnetic valve 58 is provided on the air inlet pipe 57. The air between the polarizer and the suction cup 54 is sucked into the suction pump 55 through the connecting pipe 53 and the air suction pipe 56, and then flows out from the air outlet of the suction pump 55. Due to the effect of atmospheric pressure, the suction cup 54 will fix the polarizer at this time. When the polarizer needs to be removed, the electromagnetic valve 58 is opened. Due to the effect of atmospheric pressure, the air flows back between the polarizer and the suction cup 54 through the air inlet pipe 57. When the pressure between the polarizer and the suction cup 54 is equal to the atmospheric pressure, the suction cup 54 will no longer suck the polarizer.

[0039] When the utility model is implemented, the motor 22 is first started to drive the conveyor belt 23 to rotate, and the infrared light emitter 35 is turned on, so that the light emitted by the infrared light emitter 35 will first pass through the light source outlet 33 and then through the light source receiving port 34 to be received by the infrared light receiver 36. Then, the polarizer is placed on one side of the conveyor belt 23 in sequence, and the polarizer is conveyed by the conveyor belt 23 to between the light source outlet 33 and the light source receiving port 34. At this time, it is judged whether the warping of the polarizer exceeds the standard according to the received light source. If the infrared light received by the infrared light receiver 36 is 100%, it means that the warping is within the standard. , the polarizer meets the requirements and is then conveyed by the conveyor belt 23 to the finished product collection box 7 on the side of the placement table 1 for collection. When the infrared light receiver 36 cannot receive 100% of the light from the emission source, it means that the polarizer is warped beyond the standard and needs to be picked out. The alarm 37 sends an alarm signal to the controller 6, and the controller 6 controls the motor 22 to turn off, and then controls the electric telescopic rod 51 to start, and the electric telescopic rod 51 drives the connecting block 52 to move downward, thereby driving the suction cup 54 to contact the polarizer. After that, the controller 6 controls the vacuum pump 55 to start and start to pump air, and the air between the polarizer and the suction cup 54 is connected to the vacuum pump through the connecting pipe 53. The tube 56 is sucked into the vacuum pump 55 and then flows out from the air outlet of the vacuum pump 55. Due to the effect of atmospheric pressure, the suction cup 54 will fix the polarizer at this time, and then the vacuum pump 55 stops pumping air. Then the controller 6 controls the electric telescopic rod 51 to reset, and then the controller 6 controls the motor 2 45 to start, driving the screw 44 to rotate, and then driving the moving block 46 to move, so as to move the unqualified polarizer to the top of one of the waste collection boxes 8. When the polarizer needs to be removed later, the controller 6 controls the solenoid valve 58 to open. Due to the effect of atmospheric pressure, the air flows back between the polarizer and the suction cup 54 through the air inlet pipe 57. When the pressure between the polarizer and the suction cup 54 is equal to the atmospheric pressure, the suction cup 54 will no longer hold the polarizer, and the polarizer will fall into the waste collection box 8. Then the moving block 46 will be reset. After the unqualified polarizer is sorted out, the infrared light received by the infrared light receiver 36 is restored to 100%. At this time, the controller 6 controls the motor 22 to restart and continue the above-mentioned inspection for the subsequent polarizer. The entire inspection process does not require manual observation and repeated loading and unloading, which speeds up the inspection, saves time and effort, and can realize the automatic warpage inspection of large quantities of polarizers, thereby improving the inspection efficiency of the inspection device.

[0040] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components.
