By spraying water mist on the LCD panel assembly station, the dust particles are captured by the water mist particles and fall to the ground together, reducing the floating dust particles; In the prior art, the related technology for dust removal of liquid crystal panels can refer to the Chinese patent with announcement number CN220160757U, which discloses a dust prevention device for adding COF to liquid crystal panels, including a conveying device, a pair of mounting blocks are fixedly connected to the conveying device, a pair of the mounting blocks are provided with slide rails, a slider is slidably connected to the slide rail, a support block is fixedly connected to the slider, a plurality of suction nozzles are installed on the support block, a liquid crystal panel is arranged on the plurality of suction nozzles, a pair of connecting blocks are fixedly connected to the conveying device, a dust removal roller is rotatably connected between the pair of connecting blocks, and a dust removal layer is arranged on the outer wall of the dust removal roller. The utility model arranges a nozzle on the conveying device at the front end of the COF process of adding COF to the liquid crystal panel, and the compressed air sprayed from the nozzle can clean the dust and other particles on the surface of the liquid crystal panel, and then the liquid crystal panel will pass through the dust removal roller, and the dust removal roller will remove the dust and other particles on the surface of the liquid crystal panel, so that the surface of the liquid crystal panel is clean and dust-free when the COF is added; Existing LCD panel dust removal devices often only clean and dust the LCD panel by spraying water mist onto the LCD panel assembly station or using a dust removal roller. After the dust removal roller wipes off the dust on the surface of the LCD panel, the static electricity carried by the dust may interact with the static electricity on the surface of the cleaned LCD panel, thereby causing the dust to be adsorbed onto the LCD panel again. After dust removal by the cleaning structure, frequent manual cleaning is required to ensure that the dust adsorbed on the surface will not be adsorbed to the LCD panel. Summary of the invention

In this way, the liquid crystal panel can be conveyed to facilitate continuous dust removal work on multiple groups of liquid crystal panels. The conveyor belt is a prior art that drives the conveyor belt to carry out conveying work by driving the transmission roller driven by a motor. The positive dust suppression structure can achieve a certain dust suppression effect in the dust removal frame. The air filtered by the air filter is extracted into the air duct by the blower and then transported to the air inlet, and then transmitted to the dust removal frame, so that the air pressure inside the dust removal frame is slightly higher than the outside, thereby forming a positive pressure environment, thereby preventing external dust from entering the frame, thereby achieving a dust-free environment in the dust removal frame. When the liquid crystal panel is transported to the bottom position of the spray head through the conveyor belt, the water in the water tank can be pumped into the guide pipe through the water pump, and then transported to the diversion pipe through the guide pipe and then to the spray head.

The high-definition camera 47 can perform a certain degree of detection on the surface of the LCD panel and then transmit the signal to the data processor 48 to determine whether the surface is cleaned. When it is detected that there are still impurities remaining on the surface of the panel, the signal is transmitted to the controller 50 through the data processor 48. The controller 50 controls the alarm 49 to light up to remind the staff to repeat the dust removal of the LCD panel to avoid residual phenomena.

[0034] The implementation principle of the embodiment of the present application is as follows: first, the assembled LCD panel is placed on the surface of the conveyor belt 2 and conveyed by the conveyor belt 2. The dust suction end of the vacuum cleaner 45 can perform a certain adsorption treatment on the dust on the surface of the LCD panel to facilitate subsequent cleaning. When the LCD panel is conveyed to the bottom position of the spray head 12 by the conveyor belt 2, the water in the water tank 8 can be pumped into the guide pipe 9 by the water pump 10, and then transported to the diversion pipe 11 through the guide pipe 9 and then transmitted to the spray head 12. The panel surface is sprayed to a certain extent by the spray head 12, and the dust particles are captured by the water mist particles so that the dust on the panel surface is merged with the water mist particles to facilitate subsequent dust removal work. At the same time, the positive dust suppression structure 4 can perform a certain dust suppression effect on the dust removal frame 3. The air filtered by the air filter 5 is extracted into the air duct 7 by the blower 6 and then transported to the air inlet 71, thereby being transmitted to the dust removal frame 3, so that the air pressure inside the dust removal frame 3 is slightly higher than that outside, thereby forming a positive pressure environment, thereby preventing external dust from entering the frame, thereby achieving a dust-free environment in the dust removal frame 3, and the servo motor 21 drives the drive shaft 19 to rotate, thereby driving the No. 2 gear 20 to rotate synchronously, and the rotation of the No. 2 gear 20 drives the No. 1 gear 18 on both sides to rotate in opposite directions, thereby driving the two groups of screw rods 13 to rotate synchronously, and the two groups of screw rods 13 rotate in opposite directions, thereby driving the moving blocks 14 on both sides to perform translational movements in different directions, and the movement of the moving blocks 14 can drive the fixed frame 23 and the top frame 24 to perform synchronous translational movements, and when the electric telescopic rod 25 is pushed to the bottom, the cleaning cotton strips 27 can contact the liquid crystal panel, so that the surface of the liquid crystal panel is dusted, and during the transportation of the liquid crystal panel, the two groups of cleaning cotton strips 27 are used to perform reciprocating cleaning and wiping in different directions to achieve a good dust removal effect; When the cleaning cotton strip 27 needs to be cleaned after cleaning the water mist particles and impurities on the surface of the liquid crystal panel, the driving mechanism 16 drives the cleaning cotton strip 27 to move to the top of the water collecting tank 40 at the edge of the dust removal frame 3, and the electric telescopic rod 25 pulls the connecting plate 26 to move upward in translation, thereby driving the cleaning cotton strip 27 to move to the center of the fixed frame 23. At the same time, during the upward translation of the connecting plate 26, the connecting rod 39 and the top rod 37 can be driven to move upward in synchronization, thereby driving the pushing block 36 to move upward in synchronization, and the pushing block 36 moves to push the sliding block 29 to move in translation, thereby driving the connecting frame 34 and the squeezing roller 35 to squeeze toward the middle of the fixed frame 23, thereby squeezing and cleaning the cleaning cotton strip 27 moving upward, so that the cleaning cotton strip 27 adsorbed by the cleaning cotton strip 27 Water droplets and dust impurities fall into the water collection tank 40 for collection, and the cleaning cotton strips 27 are squeezed and cleaned to achieve a self-cleaning function, avoiding the need for manual cleaning of the cleaning cotton strips 27 during the dust removal process of the LCD panel. A pipe is provided at the bottom of the water collection tank 40 to facilitate the discharge of waste water. When the dust removal of the LCD panel is completed, it is moved to the bottom of the detection frame 46 through the conveyor belt 2. The high-definition camera 47 can perform a certain degree of detection on the surface of the LCD panel and then transmit the signal to the data processor 48 to determine whether the surface is cleaned. When it is detected that there are still impurities remaining on the surface of the panel, the signal is transmitted to the controller 50 through the data processor 48. The controller 50 controls the alarm 49 to light up to remind the staff to repeat the dust removal of the LCD panel to avoid residual phenomena.
