[0040] An arc-shaped block 3 is fixedly connected to the outer surface of the second fixed block 2. A groove 31 is provided in the arc-shaped block 3, and a support hole 32 is provided in the groove 31.

[0041] Folding cloth 33, one end of the groove 31 is fixedly connected, the other end of the folding cloth 33 is provided with a first magnet 34, the folding cloth 33 is uniformly provided with a perforated hole 35, the folding cloth 33 has elasticity;

[0042] Slide rail 4, provided on the upper surface of the workbench 8, is in sliding connection with the sliding block 22;

[0043] The placing groove 6 is uniformly arranged on the upper surface of the workbench 8 and is located in the vertical direction of the slide rail 4;

[0044] The lifting cylinder 61 is fixedly connected with the bottom surface of the placing groove 6 at the input end, and is provided with a second magnet 62 at the output end. The slide rail 4 is provided with a through hole 41, and the diameter of the output end of the lifting cylinder 61 is less than or equal to the diameters of the through hole 41, the supporting hole 32 and the perforated hole 35.

[0045] The second air pump 92 is arranged in the cavity 9 and is controlled by a controller. The second fixed block 2 is provided with a second cavity 23, and the bottom of the second suction cup 21 is in communication with the second cavity 23. The second cavity 23 is provided with a second air pipe 24 at the bottom surface, and the second air pipe 24 is a flexible pipe. A pipe penetrating slot 42 is formed in one side of the slide rail 4.

[0046] The elastic cloth 36 is arranged between two adjacent grooves 31, and the end of the elastic cloth 36 extends into the groove 31 and is fixedly connected with the folding cloth 33.

[0047] Specifically, the polarizing plate to be edged is divided into two categories. The first type of polarizing plate has a size smaller than the initial state of the second fixed block 2 forming a circular ring, and the second type of polarizing plate has a size larger than the initial state of the second fixed block 2 forming a circular ring.

[0048] When the first type of polarizer needs to be edged, the staff directly places the polarizer in the middle on the first fixed block 1, controls the first air pump 91 to exhaust through the controller, and exhausts the air in the first cavity 12 along the first air pipe 13, so that the negative pressure is generated in the first cavity 12, and the adsorption of the first suction cup 11 to the polarizer is realized; then, the controller controls the jacking air cylinder 61 to output outward, the output end of the jacking air cylinder 61 passes through the through hole 41, the supporting hole 32 and the perforation 35 in turn, until the second magnet 62 is adsorbed with the first magnet 34 on the folded cloth 33, in the process of rising of the jacking air cylinder 61, the folded cloth 33 in the groove 31 slowly stretches upward from the folded state, and drives the elastic cloth 36 to rise, and the polarizer is surrounded in a ring; again, the controller starts the polishing device 82, and the edge of the polarizer is polished through the movement of the polishing device 82, at the same time, the water pump connected with the water spraying pipe 83 is started, the water spraying pipe 83 sprays water on the polarizer, after the polishing is completed, the controller closes the polishing device 82, the air pump and the water pump, and moves the polishing device 82 away from the polarizer, then, the controller controls the jacking air cylinder 61 to retract the output end, the first magnet 34 drives the folded cloth 33 to move downward, the folded cloth 33 is folded along the output end of the jacking air cylinder 61 in the perforation 35, is retracted into the groove 31, until the first magnet 34 and the second magnet 62 are separated, the output end of the jacking air cylinder 61 is retracted to the placement groove 6; then the air pump is closed to adjust the air pressure of the suction cup, and the polarizer is taken down;

[0049] When the second type of polarizer needs to be polished, first, the polarizer is placed in the middle on the first fixed block 1, and the first fixed block 1 is adsorbed to the polarizer by controlling the first air pump 91 to exhaust; then the second fixed block 2 is moved to the edge of the polarizer by controlling the electric telescopic rod 5 to extend outward, and the second air pump 92 is controlled to exhaust to remove the air in the second cavity 23 along the second air pipe 24, so that a negative pressure is formed in the second cavity 23, realizing the fixation of the second suction cup 21 to the edge of the polarizer. In this process, the hose is stretched outward through the sliding block 22 in the pipe hole 42; after the polarizer is fixed, the lifting cylinder 61 under the support block is started, and the output end of the lifting cylinder 61 passes through the through hole 41, the support hole 32 and the through hole 35 in turn, until the second magnet 62 is adsorbed to the first magnet 34 on the folded cloth 33, driving the folded cloth 33 in the groove 31 to rise, wherein when the electric telescopic rod 5 needs to be extended outward to adapt to the size of the polarizer, the distance between adjacent grooves 31 also increases, and the adjacent folded cloths 33 are fixedly connected through the elastic cloth 36, so that the folded cloth 33 and the elastic cloth 36 can still form an integral whole. For polarizers of different sizes, the folded cloth 33 can cooperate with the lifting cylinder 61 to shield the dust generated during edge polishing, further reducing the harm of dust to the health of workers; again, the polishing device 82 is started through the controller, and the edge of the polarizer is polished by moving the polishing device 82. At the same time, the water pump connected with the water spraying pipe 83 is started to spray water on the polarizer. After polishing is completed, the polishing device 82, the air pump and the water pump are turned off through the controller, and the polishing device 82 is moved away from the polarizer. Then, the output end of the lifting cylinder 61 is controlled to retract, the first magnet 34 drives the folded cloth 33 to move downward, the folded cloth 33 is folded along the output end of the lifting cylinder 61 in the through hole 35, retracted into the groove 31, until the first magnet 34 and the second magnet 62 are separated, and the output end of the lifting cylinder 61 is retracted to the placement groove 6; then the air pressure of the suction cup is adjusted by turning off the air pump, and the polarizer is taken off. Finally, the polarizer with polished edges is stored for the next operation.

[0050] It should be noted that the polishing device 82 is controlled by the controller to realize multi-angle polishing of the polarizer. The polishing device 82 is composed of a controller, a polishing blade and a moving device. The polishing device 82 is a prior art and will not be described in detail here.

[0051] Compared with the prior art, first, the present application realizes the adaptation of the polaroid polishing system to different sizes of polaroids by moving the second fixed block 2 driven by the electric telescopic rod 5, and improves the polishing efficiency; second, the cooperation of the jacking air cylinder 61, the folding cloth 33, the first magnet 34 and the second magnet 62 forms a package for dust, reduces the phenomenon of dust overflowing during polishing, and further reduces the harm of dust overflowing to the health of the operator; when a larger size of polaroid needs to be processed, the uniformly arranged placing groove 6 cooperates with the jacking air cylinder 61, the folding cloth 33 and the elastic cloth 36 to better adapt to different sizes of polaroids and package the dust generated during polishing; third, the cooperation of the sliding block 22 and the track improves the stability of the second fixed block 2; fourth, the hose passes through the pipe joint 42 to communicate with the second air pump 92, so that the second suction disc 21 better adsorbs the polaroid and improves the work efficiency; finally, compared with the prior art, the present application meets the fixing needs of the polaroid polishing system for different sizes of polaroids through a simple structure, reduces the phenomenon of dust overflowing, and improves the work efficiency.

[0052] As a preferred embodiment of the present application, the sliding rail 4 is provided with a folding cover 7, one end of the folding cover 7 is fixedly connected with the end of the sliding rail 4 away from the arc-shaped block 3, and the other end of the folding cover 7 is fixedly connected with the arc-shaped block 3.

[0053] Specifically, when the output end of the electric telescopic rod 5 extends outward, the folding cover 7 fixedly connected with the arc-shaped block 3 is folded outward, and when the output end of the electric telescopic rod 5 is retracted inward, the arc-shaped block 3 moves towards the first fixed block 1, driving the folding cover 7 to unfold to cover more of the sliding rail 4; the setting of the folding cover 7 reduces the dust generated by edge grinding from drifting into the sliding rail 4, further reducing the influence of dust on the sliding rail 4 and improving the work efficiency;

[0054] As a preferred embodiment of the present application, the first fixed block 1 is uniformly provided with threaded holes at the edges, the upper surface of the workbench 8 is provided with threaded grooves, and the first fixed block 1 is threadedly connected with the upper surface of the workbench 8 through bolts 14. Specifically, when the first fixed block 1 needs to be repaired and replaced, the threaded connection improves the work efficiency, thereby minimizing production interruption and repair time; at the same time, the first fixed block 1 is fixed at the edges through the bolts 14, avoiding the influence of threaded connection on the adsorption effect of the first suction disc 11 on the polaroid.

[0055] As a preferred embodiment of the present application, the second fixed block 2 is provided with a shielding cover 25, and the height of the shielding cover 25 is greater than that of the first fixed block 1.

[0056] When the size of the polarizing sheet is small and can only be adsorbed by the first adsorbing disc 11 on the first fixing block 1, the shielding cover 25 is placed on the second fixing block 2, at this time, the second adsorbing disc 21 is made to work by the controller, and the shielding cover 25 is firmly fixed on the second fixing block 2 by the adsorption of the second adsorbing disc 21, wherein the height of the shielding cover 25 is higher than that of the first fixing block 1, so that the shielding cover 25 forms a small surrounding ring, further increasing the shielding effect on the dust generated during polishing, and effectively preventing the dust generated during polishing of the edge of the polarizing sheet from falling on the second fixing block 2 and the second adsorbing disc 21, preventing the phenomenon that the second adsorbing disc 21 is obstructed by the dust when the polarizing sheet is fixed subsequently; and when a polarizing sheet with a larger size needs to be adsorbed, only the second adsorbing disc 21 needs to be stopped, and the shielding cover 25 can be manually removed, so that the second adsorbing disc 21 can be used to adsorb the polarizing sheet subsequently, further improving the work efficiency.

[0057] As a preferred embodiment of the present application, the water spraying pipe 83 is made of a telescopic pipe for adjusting the angle. Specifically, before polishing the polarizing sheet, the angle of the water spraying pipe 83 is manually adjusted so that the water spraying pipe 83 can more accurately spray water on the edge polishing position of the polarizing sheet, cool and lubricate the edge polishing of the polarizing sheet, and further improve the quality of the edge polishing of the polarizing sheet.

[0058] As a preferred embodiment of the present application, the folding cloth 33 and the elastic cloth 36 are both made of elastic soft shell fabric. Specifically, the elastic soft shell fabric facilitates the folding of the folding cloth 33, while meeting the horizontal and vertical stretching effect.
