DETAILED DESCRIPTION

[0017] The following is a further specific description of the technical solution of the present invention through embodiments in combination with the attached Figure 1-3 drawings.

[0018] A cleaning device for processing liquid crystal display screens includes two sets of frames 1 and a conveyor belt 2 arranged between the two sets of frames 1. The top of the conveyor belt 2 is evenly provided with bases 3. A groove 4 for accommodating the display screen 5 is provided on the top of the base 3. Locking mechanisms 6 for fixing the display screen 5 are provided on both sides of the base 3;

[0019] A U-shaped frame 7 is mounted on the frame 1. A hydraulic rod 8 is provided at the top of the U-shaped frame 7. An installation plate 9 is provided at the bottom of the hydraulic rod 8. A box body 11 buckling on one set of bases 3 is fixed at the bottom of the installation plate 9 through a vertical rod 10. An aggregate box 12 located outside the corresponding base 3 is provided on one side inside the box body 11. A round pipe 13 sequentially penetrating through the top wall and the installation plate 9 is further provided in the middle of the box body 11. The round pipe 13 is connected to a suction fan through a flexible pipe 14. Cross bars 15 and a cross pipe 16 communicated with the inside of the round pipe 13 are respectively provided on both sides of the round pipe 13 inside the box body 11. Suction holes 17 are evenly provided on the side wall of the cross pipe 16. A cleaning layer 18 made of materials such as dust-free cloth is sleeved on the cross bar 15;

[0020] A motor 19 is provided at the bottom of the installation plate 9. A gear 20 is provided on the output shaft of the motor 19. A toothed disc 21 meshing with the gear 20 is provided on the round pipe 13.

[0021] As Figure 2 、 3 shown, a scraper 22 connected to the corresponding inner wall of the box body 11 is provided directly above the opening of the aggregate box 12. The scraper 22 is located below the cross bar 15 and the cross pipe 16. The top end of the scraper 22 is not lower than the bottom horizontal plane of the cleaning layer 18. The bottom end surface of the cleaning layer 18 is attached to the top end surface of the corresponding display screen 5. The top end of the display screen 5 extends to the outside of the top of the groove 4.

[0022] In this embodiment, the ends of the cross pipe 16 and the bottom end of the round pipe 13 are both hermetically arranged. Bearings for fixing the round pipe 13 are provided on both the top wall of the box body 11 and the side wall of the installation plate 9.

[0023] In the present embodiment, the cleaning layer 18 is covered on the screw tube, and the screw tube is fixedly screwed with the cross bar 15. The side wall of the box body 11 is provided with a mounting hole corresponding to the cross bar 15, and a sealing plug is provided in the mounting hole. When the cleaning layer 18 needs to be replaced, it is only necessary to open the mounting hole and rotate the screw tube, so that the screw tube is separated from the cross bar 15, and the cleaning layer 18 is driven to slide out of the mounting hole, and then it is removed to replace a new component. When the bottom end face of the cleaning layer 18 is seriously worn during use, the screw tube can be rotated to rotate on the cross bar 15 to adjust the bottom end face direction at this time, so that different end faces of the cleaning layer outside the screw tube can clean the display screen 5. In this process, it is necessary to ensure that even after the cleaning layer 18 changes its direction, the rotating round tube 13 can cover the entire top end face of the corresponding display screen 5 when the rotating round tube 13 drives the cross bar 15 and the cleaning layer 18 to rotate in the box body 11.

[0024] In this embodiment, a connecting pipe 23 is disposed in the top opening of the circular tube 13, the pipeline 14 is connected to the connecting pipe 23, and a bracket 24 for fixing the connecting pipe 23 is disposed on the top of the mounting plate 9. When the motor 19 drives the circular tube 13 to rotate through the gear 20 and the toothed disc 21, the circular tube 13 will rotate on the connecting pipe 23, and at this time, the mounting plate 9 is fixed to the connecting pipe 23 and the pipeline 14 through the bracket 24 to prevent the two from rotating together with the circular tube 13, thereby preventing the pipeline 14 from rotating and finally being twisted off.

[0025] The locking mechanism 6 includes an L-shaped plate 61 disposed on the outside of the base 3. The vertical end of the L-shaped plate 61 and the side wall of the groove 4 are both provided with through holes for the slide bar 62 to pass through. One end of the slide bar 62 abuts against the side wall of the display screen 5. The other end of the slide bar 62 is provided with a pull ring. The slide bar 62 is also provided with a convex seat 63 abutting against the outer wall of the base 3. The slide bar 62 between the convex seat 63 and the side wall of the vertical end of the L-shaped plate 61 is also covered with a spring 64. The surface of the slide bar 62 is provided with a flexible protective layer. Figure 3 As shown, the driving force generated by the expansion of the spring 64 drives the slide bar 62 to move into the groove 4 through the convex seat 63, so that the end of the slide bar 62 abuts against the side wall of the display screen 5, and then the display screen 5 is locked and fixed in the groove 4 to prevent the display screen 5 from sliding out of the groove 4 for subsequent processing. When the display screen 5 needs to be taken out, it is only necessary to pull the slide bar 62 outward to make it slide in the through hole, while it squeezes the spring 64 through the convex seat 63 and the vertical end of the L-shaped plate 61, so that the end of the slide bar 62 is separated from the side wall of the display screen 5. At this time, the display screen 5 can be conveniently taken out of the groove 4.

[0026] The method of using the present invention is as follows: the display screen 5 is fixed in the base 3 at the upstream of the conveyor belt 2, and the conveyor belt 2 sequentially conveys the display screen 5 in the base 3 above it to the position directly below the mold frame 7 to be cleaned;

[0027] like Figure 2 As shown, when the base 3 is displaced to the position just below the opening of the box 11, the conveyor belt 2 stops moving, and the hydraulic rod 8 drives the box 11 and the collection box 12 and other components to move downward through the mounting plate 9 and the vertical rod 10, so that the box 11 is buckled on the corresponding base 3 and contacts the top surface of the conveyor belt 2, and the collection box 12 is located on one side of the base 3. At this time, the bottom end surface of the cleaning layer 18 is set in contact with the top surface of the display screen 5 on the base 3, and the motor 19 drives the round tube 13 to rotate on the connecting tube 23 through the gear 20 and the gear ring 21. The circular tube 13 also drives the horizontal tube 16 and the horizontal rod 15 to rotate, wherein the horizontal rod 15 drives the cleaning layer 18 to contact the top surface of the display screen 5 to wipe the end surface, thereby removing impurities on the end surface, and when the horizontal tube 16 is driven by the circular tube 13 to rotate above the display screen 5, the strong suction force generated by the exhaust fan through the pipeline 14, the connecting tube 23, the circular tube 13, the horizontal tube 16 and the suction hole 17 can clean the top surface of the wiped display screen 5 again, so as to improve the cleaning efficiency and effect of the display screen 5;

[0028] The scraper 22 will scrape off the impurities adhered to the bottom of the cleaning layer 18 and drop them into the collecting box 12 for silting up, so that the cleaning layer 18 can continue to clean the display screen 5. When the horizontal tube 16 moves to the top of the collecting box 12, the suction force generated by it can also extract the fine impurities in the collecting box 12 and the fine particles that may be diffused in the box body 11, so as to improve the working environment in the box body 11. After the cleaning is completed, the hydraulic rod 8 drives the box body 11 and other components to move up and reset, and the conveyor belt 2 transports the next group of bases 3 and display screen 5 to the bottom of the box body 11. Then the box body 11 and other components move down to clean them, so as to realize uninterrupted cleaning of the product, thereby effectively improving the work efficiency and effect. At the same time, after a certain period of time, the impurities in the collecting box 12 are cleaned and the cleaning layer 18 can be replaced.

[0029] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
