Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device for display screen production. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat panel display used in televisions and computers. Their advantages include low power consumption, small size, and low radiation. LCDs utilize a liquid crystal solution in two polarizing materials; when an electric current passes through the liquid, the crystals rearrange to achieve image formation. Currently, ultrasonic cleaning equipment is required in the production process of LCDs.

[0003] A search revealed Chinese patent CN215940878U, which discloses a cleaning device for LCD screen production. The device includes two sets of support plates, with a connecting plate fixedly connected between them. A first spring is fixedly connected to the inner side of each set of support plates, and a cleaning tank is fixedly connected between the two sets of first springs. An ultrasonic generator is fixedly connected to the bottom of the cleaning tank. A top plate is fixedly connected to the top of each support plate, and telescopic cylinders are fixedly connected to the left and right sides of the bottom of the top plate. A connecting plate is fixedly connected to the bottom of each telescopic cylinder. The advantages of this invention are: the display screen is adsorbed and fixed using an adsorption mechanism; activating the telescopic cylinder pushes the connecting plate to position the display screen inside the cleaning tank; activating the ultrasonic generator causes the motor to rotate the placement plate, making the display screen rotate within the cleaning tank. This ensures sufficient contact area between the display screen and the air bubbles in the cavity, thus guaranteeing the cleaning effect and not affecting subsequent work.

[0004] However, the above design still has shortcomings. Once the display screen is fixed, it is not easy to rotate it during the cleaning process, which makes it difficult to clean different sides of the display screen and reduces the cleaning efficiency of the display screen.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] Please see Figure 1-5This utility model provides an embodiment of a cleaning device for display screen production, comprising a cleaning tank 3, a control panel 2 fixedly installed on the upper left side of the cleaning tank 3, a cleaning chamber 31 inside the cleaning tank 3, an electric push rod 1 fixedly installed on the top of the cleaning tank 3, a lifting plate 10 fixedly connected to the output end of the electric push rod 1, and the lifting plate 10 movably disposed inside the upper part of the cleaning chamber 31, a plurality of through slots 9 being formed on the surface of the lifting plate 10, a plurality of first clamping frames 11 being rotatably disposed on the bottom of the lifting plate 10, ultrasonic generators 12 being detachably installed on both sides of the inner wall of the cleaning chamber 31, a servo motor 8 fixedly installed on the bottom of the cleaning tank 3, a first rotating rod 25 fixedly connected to the output end of the servo motor 8, and a first rotating rod 25 being fixedly sleeved on the outer wall of the first rotating rod 25. There is a first toothed disc 26, and a second toothed disc 29 is meshed with both sides of the first toothed disc 26. A second rotating rod 30 is fixedly connected inside the second toothed disc 29. A second clamping frame 24 is fixedly connected to the top of the first rotating rod 25 and the second rotating rod 30. A limit screw 28 is threaded through the outer wall of the first clamping frame 11 and the second clamping frame 24. A limit pad 27 is fixedly connected to the end of the two limit screws 28 that are close to each other. A connecting pipe 5 is fixedly installed at the top of the cleaning chamber 31. A limit plug 4 is movably installed at the opening of the connecting pipe 5. A drain pipe 13 is fixedly installed at the lower right side of the cleaning chamber 31. A valve 14 is installed on the drain pipe 13. A movable door 7 is rotatably installed on the front end face of the cleaning box 3. A transparent window 6 is fixedly installed on the front end face of the movable door 7.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, when cleaning the display screen, first open the movable door 7, then place the bottom of the display screen inside the second clamping frame 24. Next, start the electric push rod 1, which will drive the lifting plate 10 downward through its output end. The downward movement of the lifting plate 10 will drive the first clamping frame 11 downward until the inner side of the first clamping frame 11 contacts the top of the display screen. Then, close the electric push rod 1. Next, rotate the multiple limit screws 28 to move the limit pad 27 towards the display screen until it contacts the display screen, thus fixing the display screen. Then, pull out the limit plug 4 and add an appropriate amount of cleaning water into the cleaning chamber 31 through the connecting pipe 5. Then, insert the limit plug 4 into the connecting pipe 5. Next, start the ultrasonic generator 12 and the servo motor 8 respectively. The ultrasonic generator 12 can generate ultrasonic waves to clean the display screen, and the output of the servo motor 8 can drive the first rotating rod 25 to rotate slowly. The rotation of the first rotating rod 25 drives the first gear plate 26 to rotate, and the rotation of the first gear plate 26 drives the second rotating rod 30 to rotate through the second gear plate 29. The rotation of the first rotating rod 25 and the second rotating rod 30 drives the second clamping frame 24 to rotate. The rotation of the second clamping frame 24, in conjunction with the first clamping frame 11, drives the display screen to rotate. By facilitating the rotation and cleaning of the display screen, it is convenient to clean different surfaces of the display screen, thereby improving the cleaning efficiency of the display screen. This solves the problem that when the display screen is fixed, it is not convenient to rotate the display screen during the cleaning process, which makes it difficult to clean different surfaces of the display screen and reduces the cleaning efficiency of the display screen.

[0029] A mounting box 15 is fixedly connected to the lower left side of the cleaning box 3. The mounting box 15 has a mounting cavity 20 inside. An air pump 22 is installed on the right side of the mounting cavity 20. The input end of the air pump 22 is connected to the inside of the mounting cavity 20 through a pipe. A nozzle 21 is fixedly connected to the output end of the air pump 22. A heating wire 23 is installed inside the mounting cavity 20. An air inlet 16 is opened on the left side of the mounting cavity 20. A threaded cap 19 is threadedly connected to the inner wall of the air inlet 16. A fixing hole 18 is opened through the surface of the threaded cap 19. A dustproof net 17 is fixedly installed inside the fixing hole 18.

[0030] Specifically, such as Figure 2 and Figure 3As shown, during use, after the display screen is cleaned, the valve 14 can be opened, and the cleaning water can be discharged through the drain pipe 13. After the cleaning water is discharged, the limit plug 4 can be pulled out again, and then the air pump 22 and heating wire 23 can be started respectively. The heating wire 23 can heat the air in the mounting cavity 20, and the air pump 22 can draw the heated air into the nozzle 21. Finally, the air is sprayed out through the nozzle 21 to dry the cleaned display screen, thereby shortening the display screen production process and improving the display screen production efficiency. During the process, air containing high humidity will be discharged through the connecting pipe 5, which facilitates the exchange of humidity inside the chamber with the outside air, thereby improving the drying efficiency. At the same time, the dustproof net 17 can prevent external dust from entering the installation cavity 20. After a period of time, the threaded cover 19 can be rotated until it is detached from the air inlet 16, and then the dustproof net 17 can be cleaned. After cleaning, the threaded cover 19 can be screwed back into the air inlet 16. The dustproof net 17 can be easily disassembled, cleaned and installed, thus ensuring its filtration efficiency.

[0031] Working principle: In this application, when the display screen needs to be cleaned, first open the movable door 7, then place the bottom of the display screen inside the second clamping frame 24, then start the electric push rod 1, which drives the lifting plate 10 to move downward through the output end of the electric push rod 1. The downward movement of the lifting plate 10 drives the first clamping frame 11 to move downward until the inner side of the first clamping frame 11 contacts the top of the display screen. Then close the electric push rod 1, then rotate multiple limit screws 28, causing the limit pad 27 to move in the direction close to the display screen until it contacts the display screen, thus completing the fixation of the display screen. Then pull out the limit plug 4 and add an appropriate amount of cleaning water into the cleaning chamber 31 through the connecting pipe 5. Then insert the limit plug 4 into the connecting pipe 5. Then start the ultrasonic generator 12 and the servo motor 8 respectively, which can generate ultrasonic waves to clean the display screen through the ultrasonic generator 12, and drive the first rotating rod 25 to rotate slowly through the output end of the servo motor 8. The rotation of the first rotating rod 25 drives the first gear plate 26 to rotate, and the rotation of the first gear plate 26 drives the first gear plate 26 to rotate. The second gear plate 29 drives the second rotating rod 30 to rotate. The rotation of the first rotating rod 25 and the second rotating rod 30 drives the second clamping frame 24 to rotate. The rotation of the second clamping frame 24, in conjunction with the first clamping frame 11, drives the display screen to rotate. By facilitating the rotation and cleaning of the display screen, it is possible to clean different surfaces of the display screen, thereby improving the cleaning efficiency of the display screen. Secondly, after the display screen is cleaned, the valve 14 can be opened, and the cleaning water can be discharged through the drain pipe 13. After the cleaning water is discharged, the limit plug 4 is pulled out again, and then the air pump 22 and the heating wire 23 are started respectively. The air in the mounting cavity 20 is heated by the heating wire 23, and the heated air is pumped into the nozzle 21 by the air pump 22. Finally, the air is sprayed out through the nozzle 21 to dry the cleaned display screen, thereby shortening the display screen production process and improving the production efficiency of the display screen. During this process, the air containing a large amount of moisture will be discharged through the connecting pipe 5, thereby facilitating the exchange of moisture in the chamber with the outside air and improving the drying efficiency.
