A mounting frame 6 is fixed at the output end of the adjusting cylinder 5. A material picking component 7 for picking up the polarizer is provided at the bottom of the mounting frame 6. A protective plate 8 for covering the placement slot 3 is provided on the placement slot 3. The size of the protective plate 8 is larger than that of the placement slot 3 to ensure that the protective plate 8 can completely cover the placement slot 3. An auxiliary component 9 for opening the protective plate 8 is provided on the workbench 1.

[0022] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings: Please refer to Figure 1-Figure 8 In this embodiment: by placing the polarizer and the substrate in a placement slot 3 at a specific position, the polarizer is taken out by using the material taking component 7, and then the polarizer is moved to the substrate by the rodless cylinder 4 for patching, and the patching accuracy is high.

[0023] Among them, the material taking component 7 includes a fixed box 10, which is fixed at the bottom of the mounting frame 6, and a partition 11 is symmetrically fixed in the fixed box 10, and a sealing plate 12 is fixed at the bottom between the two partitions 11. The sealing plate 12 is provided with evenly distributed through holes 13, and a piston plate 14 is slidably arranged between the two partitions 11. A piston rod 15 is fixed on the top of the piston plate 14. The top of the piston rod 15 passes through the top of the fixed box 10 and is fixed with a bracket 16. The piston rod 15 is slidably connected to the top of the fixed box 10, and an auxiliary cylinder 17 is fixed in the mounting frame 6, and the output end of the auxiliary cylinder 17 is fixed to the top of the bracket 16; It is worth noting that the bottom of the sealing plate 12 protrudes from the bottom of the fixing box 10, and the bottom of the sealing plate 12 matches the size of the placement groove 3, so that the sealing plate 12 is accurately positioned above the polarizer. After the polarizer is taken out by using the sealing plate 12, the polarizer can be accurately placed on the substrate later. The principle of the material taking component 7 driving the polarizer to be taken out from the placement slot 3 is as follows: the mounting frame 6 and the fixed box 10 are moved to the top of the placement slot 3 where the polarizer is placed by the rodless cylinder 4, and the mounting frame 6 and the fixed box 10 are driven to move downward as a whole by the adjusting cylinder 5 until the sealing plate 12 at the bottom of the fixed box 10 is against the polarizer, and then the bracket 16 is driven to move upward by the auxiliary cylinder 17, and then the piston plate 14 in the fixed box 10 is driven upward by the piston rod 15, so that the air pressure between the two partitions 11 in the fixed box 10 is reduced, and the polarizer is adsorbed to the bottom of the sealing plate 12 by atmospheric pressure through the through hole 13 on the sealing plate 12, and then the mounting box and the polarizer are driven to move upward as a whole by the adjusting cylinder 5 to take the polarizer out of the placement slot 3.

[0024] At the same time, the auxiliary component 9 includes a fixed frame 18, and there are two fixed frames 18. The two fixed frames 18 are respectively arranged on the outside of the two placement grooves 3. The fixed frame 18 is fixed to the workbench 1, and an upper rotating shaft 19 and a lower rotating shaft 20 are rotatably arranged in the fixed frame 18. An upper gear 21 is fixed on the upper rotating shaft 19, and a lower gear 22 is fixed on the lower rotating shaft 20. Evenly distributed external teeth 23 are fixed on the top of the protective plate 8, and the lower gear 22 is meshed and connected with the external teeth 23. A gear shaft 24 is fixed on the same side of the upper rotating shaft 19 and the lower rotating shaft 20, and a toothed belt 25 is meshed between the two gear shafts 24. The two gear shafts 24 are driven by the toothed belt 25. Auxiliary plates 26 are symmetrically arranged on the outside of the mounting frame 6, and evenly distributed tooth grooves 27 are arranged on the outside of the auxiliary plate 26. The tooth grooves 27 are meshed and matched with the upper gear 21; It is worth noting that a limit plate 28 is provided on the outside of the fixing frame 18, and the limit plate 28 is symmetrically arranged on the outside of the protection plate 8. The limit plate 28 is fixed to the workbench 1, and the protection plate 8 is slidably connected to the limit plate 28. The symmetrically arranged limit plates 28 are used to limit the travel path of the protection plate 8 to prevent the protection plate 8 from deviating from the predetermined path during the movement. In addition, the upper gear 21 is the same as the lower gear 22, and the auxiliary plate 26 moves downward along with the fixed box 10, and the protective plate 8 moves out of the placement slot 3 by the same distance, so as to facilitate the control of the movement range of the protective plate 8; The principle of the auxiliary component 9 driving the protective plate 8 to move away from the placement slot 3: when the adjusting cylinder 5 drives the mounting frame 6 and the fixed box 10 to move downward, the auxiliary plate 26 drives the upper rotating shaft 19 to rotate through the meshing of the tooth groove 27 with the upper gear 21, thereby driving the lower rotating shaft 20 to rotate synchronously through the cooperation of the gear shaft 24 and the toothed belt 25, thereby driving the lower gear 22 to rotate, and driving the protective plate 8 on the placement slot 3 to gradually move away from the placement slot 3 through the meshing of the lower gear 22 and the external teeth 23, until the protective plate 8 is completely separated from the placement slot 3, at which time the auxiliary plate 26 is no longer in contact with the upper gear 21, thereby facilitating the normal subsequent material removal or patch operations.

[0025] In this technical solution, reference Figure 4-Figure 6, the fixed box 10 is symmetrically provided with pressure rollers 29, the two pressure rollers 29 are respectively arranged on the outside of the two partitions 11, the outer side of the partition 11 is slidably provided with a movable frame 30, the pressure rollers 29 are rotatably connected with the inside of the movable frame 30, the top of the movable frame 30 is fixedly provided with a spring telescopic frame 31, the top of the spring telescopic frame 31 is fixedly provided with an auxiliary rod 32, the auxiliary rod 32 passes through the top of the fixed box 10 and is fixed to the bracket 16; The length of the pressing roller 29 is greater than the width of the sealing plate 12; After the polarizer is placed on the substrate, the bracket 16 is driven downward by the auxiliary cylinder 17, thereby releasing the polarizer from the bottom of the sealing plate 12. As the auxiliary cylinder 17 continues to drive the bracket 16 downward, the pressure roller 29 moves out from the bottom of the fixed box 10, and the rodless cylinder 4 drives the fixed box 10 to move toward the placement slot 3 where the polarizer is placed, driving the pressure roller 29 to roll on the polarizer and the substrate to press the polarizer and the substrate together.

[0026] The polarizer mounting method of the polarizer mounting machine of the technical solution comprises the following steps: S1, placing the polarizer and the substrate in two placement slots 3 respectively, sliding the protection plate 8 to the top of the placement slots 3 to cover the placement slots 3; S2, the mounting frame 6 is driven by the rodless cylinder 4 to move to the top of the placement slot 3 where the polarizer is placed, and the adjusting cylinder 5 is started to drive the mounting frame 6 and the fixing box 10 to move downward. At this time, the auxiliary plate 26 drives the upper rotating shaft 19 to rotate through the meshing of the tooth groove 27 with the upper gear 21, thereby driving the lower rotating shaft 20 to rotate synchronously through the cooperation of the gear shaft 24 and the toothed belt 25, thereby driving the lower gear 22 to rotate, and driving the protection plate 8 on the placement slot 3 to gradually move away from the placement slot 3 through the meshing of the lower gear 22 and the external teeth 23, until the protection plate 8 is completely separated from the placement slot 3, and at this time, the auxiliary plate 26 is no longer in contact with the upper gear 21; S3, the sealing plate 12 at the bottom of the fixed box 10 contacts the polarizer in the placement slot 3, and the auxiliary cylinder 17 drives the bracket 16 to move upward, thereby driving the piston rod 15 and the piston plate 14 to move upward, reducing the air pressure between the two partitions 11 in the fixed box 10, and using the atmospheric pressure to adsorb the polarizer on the bottom of the sealing plate 12; S4, using the rodless cylinder 4 to drive the fixed box 10 with the polarizer to move to the top of the placement slot 3 where the substrate is placed, repeat the operation process of the adjustment cylinder 5 in S2, remove the protection plate 8 on the placement slot 3 where the substrate is placed, and then place the polarizer on the substrate; S5. Use the auxiliary cylinder 17 to drive the bracket 16 to move downward, so as to release the polarizer from the bottom of the sealing plate 12, and place the polarizer on the substrate. As the auxiliary cylinder 17 continues to drive the bracket 16 to move downward, the pressure roller 29 moves out from the bottom of the fixed box 10, and drives the fixed box 10 to move toward the placement slot 3 where the polarizer is placed through the rodless cylinder 4, driving the pressure roller 29 to roll on the polarizer and the substrate, pressing the polarizer and the substrate together to complete the patch operation.
