Description

TECHNICAL FIELD

[0001] The application relates to the technical field of polarizing plates, in particular to a polarizing plate sorting machine. BACKGROUND

[0002] The full name of a polarizing plate is a polarized light plate. Imaging of a liquid crystal display must rely on polarized light. All liquid crystals have front and back two polarizing plates closely attached to the liquid crystal glass to form a liquid crystal plate with a total thickness of about 1 mm.

[0003] A common polarizing plate sorting machine is composed of an entering plate machine, a cleaning machine, a detection machine and a plate collecting machine. When the polarizing plate is transported to the cleaning machine, the cleaning rollers in the cleaning machine adsorb the dust on the surface of the polarizing plate and paste the adsorbed dust on the dust collection paper.

[0004] According to the related technology in the above, the cleaning roller is usually a silica gel roller. When the silica gel roller has poor adsorption, the silica gel roller in the cleaning machine needs to be cleaned or replaced. Each replacement needs to take the silica gel roller out of the cleaning machine, so that the transmission, cleaning and detection of the polarizing plate need to be temporarily stopped, thereby affecting the sorting efficiency of the polarizing plate.

When the unqualified polarizer is detected, the piston rod of the cylinder 44 retracts, the turnover conveyor belt 43 turns down, the unqualified polarizer passes through the space between the turnover conveyor belt 43 and the first conveyor 5 and enters the storage assembly 42 at the bottom of the first conveyor 5, so that the sorting of the polarizer is completed.

[0059] As Figure 3 , the storage assembly 42 comprises a storage box 421 and a storage bottom plate 422, two second supporting rods 423 are arranged on the storage bottom plate 422, the two second supporting rods 423 are commonly connected with a supporting plate 424, the length of one second supporting rod 423 is greater than that of the other second supporting rod 423, the supporting plate 424 is arranged obliquely, the storage box 421 is obliquely placed on the supporting plate 424, and the storage bottom plate 422 is provided with a lifting adjusting part 9 for driving the two second supporting rods 423 to lift simultaneously.

[0060] As Figure 3 , the adjusting part 9 comprises a rotating sleeve 91 and a rotating handle 92, the rotating handle 92 is rotatably connected with the storage bottom plate 422, the rotating handle 92 is connected with a worm 93, two rotating sleeves 91 are rotatably connected with the storage bottom plate 422, a worm wheel 94 is sleeved on the rotating sleeve 91, the two worm wheels 94 are meshed with the worm 93, one end of the second supporting rod 423 away from the supporting plate 424 is provided with a thread, and the second supporting rod 423 is threadedly connected with the rotating sleeve 91.

[0061] When it is necessary to adjust the height of the storage box 421, the rotating handle 92 is rotated, the rotating handle 92 drives the worm 93 to rotate, the worm 93 drives the two worm wheels 94 to rotate, the two worm wheels 94 drive the rotating sleeves 91 to rotate, and the rotating sleeves 91 drive the second supporting rods 423 to stretch and retract, so that the two second supporting rods 423 stretch and retract simultaneously, and the height of the storage box 421 is adjusted conveniently.

[0062] The principle of the embodiment of the present application is that the polarizing sheet is transmitted to the first conveyor 5 by the first suction disc mechanical hand 13 and the second suction disc mechanical hand 14, then the polarizing sheet enters the cleaning shell 2 to be cleaned by the cleaning roller 27, then the polarizing sheet is transmitted to the AOI detection equipment 3 to be detected, when the detection is qualified, the polarizing sheet is transmitted to one of the storage boxes 421 by the second conveyor 41 and the first conveyor 5, when the detection is unqualified, the cylinder 44 drives the turnover conveyor belt 43 to turn over, the polarizing sheet is transmitted to the other storage box 421 through the space between the turnover conveyor belt 43 and the first conveyor 5, and the sorting of the polarizing sheet is completed.

[0063] When the cleaning roller 27 needs to be replaced, before the next polarizing sheet reaches the cleaning shell 2, the second motor 24 drives the rotating rod 25 to rotate, the rotating rod 25 drives the first rotating shaft 26 to turn over, so that the cleaning roller 27 that needs to be cleaned is turned into the cleaning shell 2, and the new cleaning roller 27 is turned out of the cleaning shell 2, then by pulling the pull rod 72, the first rack 73 of the pull rod 72 drives the gear 75 to rotate, the gear 75 drives the second rack 77 to move, so that the fixing rod 76 fixes the cleaning roller 27 and pulls out the cleaning roller 27 from the cleaning shell 2, so that the replacement of the cleaning roller 27 can be realized without stopping the transmission of the polarizing sheet, and the sorting efficiency of the polarizing sheet is improved.

[0064] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
