[0018] 1. When processing the LCD screen, it is necessary to clean its surface and then dry it through the drying device. When drying, start the driving motor and the servo motor. The driving motor can drive the drying rack to rotate through the connecting shaft, and at the same time drive the large gear and the small gear to mesh. The small gear can drive the bevel gear set and the transmission rod to rotate. When the transmission rod rotates, it can drive the first toggle block to slide in the through groove inside the connecting plate, so that the connecting plate can move back and forth. When the connecting plate moves, the hair dryer head can be toggled through the movable groove at the bottom to swing back and forth, so that the hair dryer head can dry the LCD screen on the top drying rack. The swinging hair dryer head covers a larger range and evenly dries the LCD screen. The servo motor drives the transmission belt to move through the conveyor roller. The transmission belt can drive the second toggle block on its outer side to slide in the slide groove in the moving rod. The moving rod is toggled to move. After the sponge on one side of the moving rod contacts the display placed on the drying rack, the water droplets on the display will be evenly distributed to prevent the water droplets from gathering and prolong the drying time. In this way, the drying device can evenly dry the LCD screen through the above operation to improve the drying efficiency.

[0019] 2. When processing the LCD screen, it is necessary to clean its surface and then dry it through the drying device. By pulling the handle, the handle will move the cleaning brush. When the cleaning brush moves, the protrusion on one side will slide in the wave groove, and the wave groove can make the cleaning brush move up and down. The first limit rod and the second limit rod can limit the cleaning brush and the handle. In this way, when the cleaning brush moves along the direction of the first limit rod, the cleaning brush can also move in another direction, brushing the filter plate up and down during translation, increasing the movement form, and can clean the filter plate in multiple ranges and angles, thereby improving the cleaning effect. In this way, the filter plate at the bottom of the drying box in the drying device can be efficiently cleaned through the above operation.

[0020] 3. When processing the LCD screen, it is necessary to clean its surface and then dry it through the drying device. When fixing the LCD screen, put the LCD screen on the bracket inside the drying rack. After putting it in, start the electric push rod to push the first movable plate to move. When the first movable plate moves, the first connecting rods on both sides will pull the two groups of second movable plates to move. When the two groups of second movable plates move, the third movable plate can be pushed to move by the second connecting rod. The limiting column will limit the first movable plate, the second movable plate and the third movable plate. The limiting plate will contact the frame of the LCD screen through the internal "V"-shaped rubber block to flexibly limit the LCD screen. At this time, the drying rack can be rotated to dry the internal LCD screen. In this way, the LCD screen in the drying device can be quickly limited through the above operations.

A through groove matching the first toggle block 16 is provided inside the connecting plate 17. A fixed box 18 is welded and fixed to the top of the body 1, and a servo motor 19 is installed on one side of the fixed box 18. A conveying roller 20 is fixed to the output end of the servo motor 19, and a movable groove for sliding the bottom hose of the hair dryer 9 is provided inside the connecting plate 17; a transmission belt 21 is sleeved on the outer side of the conveying roller 20, and a second toggle block 22 is fixed to the outer side of the transmission belt 21, and a moving rod 23 is slidably connected to the outer side of the second toggle block 22, and a sliding groove matching the second toggle block 22 is provided inside the moving rod 23, and a sponge block is fixed to the side of the moving rod 23 close to the drying rack 3, and through holes for sliding the sliding rod 24 are provided on both sides of the moving rod 23, and the two ends of the sliding rod 24 are fixedly connected to the drying rack 3, the large gear 11 and the small gear 12 constitute a meshing transmission structure, and the first toggle block 16 and the connecting plate 17 constitute a sliding structure.

[0032] In specific implementation, when processing the liquid crystal display screen, it is necessary to clean its surface and then dry it through the drying device. When drying, the drive motor 2 and the servo motor 19 are started. The drive motor 2 can drive the drying rack 3 to rotate through the connecting shaft 10, and at the same time drive the large gear 11 and the small gear 12 to mesh. The small gear 12 can drive the first bevel gear 13 and the second bevel gear 14 to mesh, so that the transmission rod 15 in the second bevel gear 14 rotates. When the transmission rod 15 rotates, it can drive the first toggle block 16 to slide in the through groove inside the connecting plate 17. , so that the connecting plate 17 moves back and forth, and when the connecting plate 17 moves, the blowing head 9 can be toggled through the movable groove at the bottom to swing back and forth, so that the blowing head 9 dries the LCD screen on the top drying rack 3, and the swinging blowing head 9 can cover a larger range, and the LCD screen is evenly dried. Since the large gear 11 drives the small gear 12 to rotate, and the number of teeth of the large gear 11 is greater than that of the small gear 12, when the drying rack 3 rotates one circle, the first toggle block 16 can be driven to rotate multiple circles, so that the blowing head 9 swings multiple times, and the effect of uniform drying is achieved;

[0033] The servo motor 19 will drive the transmission belt 21 to move through the conveyor roller 20. The transmission belt 21 can drive the second toggle block 22 on its outer side to slide in the slide groove in the moving rod 23, and the moving rod 23 is toggled to move. The two sides of the moving rod 23 are limited by the slide bar 24 and can only move in the horizontal direction. The moving rod 23 will reciprocate once driven by the servo motor 19. After the sponge on one side of the moving rod 23 contacts the display screen placed on the drying rack 3, it will evenly distribute the water droplets on the display screen to prevent the water droplets from gathering and extend the drying time. When the moving rod 23 finishes one reciprocating movement, it will contact the outer side of the drying rack 3, thereby squeezing out the water on the sponge on one side of the moving rod 23. In this way, the drying device can evenly dry the LCD screen through the above-mentioned operation, thereby improving the drying efficiency.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 A first limiting rod 25 is welded and fixed to the bottom of the drying box 4, and a cleaning brush 26 is slidably connected to the outer side of the first limiting rod 25, and a moving groove matching the first limiting rod 25 is provided inside the cleaning brush 26; a protrusion 27 is welded and fixed to one side of the cleaning brush 26, and a wave groove 28 for the protrusion 27 to slide is provided on one side of the drying box 4, and a rectangular groove for the handle 29 to slide is provided on one side of the cleaning brush 26; balls 30 are rollingly connected on all sides of the handle 29, and a round hole for the second limiting rod 31 to slide is provided inside the handle 29, and both ends of the second limiting rod 31 are fixedly connected to the drying box 4, and the handle 29 and the second limiting rod 31 form a sliding structure.

[0035] In specific implementation, when processing the LCD screen, it is necessary to clean its surface and then dry it through a drying device. When the fan 6 in the drying box 4 is running, one side needs to exhaust air to the outside. In order to prevent dust from being sucked into the fan 6, a filter plate 5 needs to be set on one side of the air inlet of the fan 6. The filter plate 5 needs to be cleaned after long-term use. By pulling the handle 29, the handle 29 will move the cleaning brush 26, and the ball 30 will replace the handle 29 to roll with the inside of the cleaning brush 26, thereby reducing the friction when the handle 29 moves. When the cleaning brush 26 moves, the protrusion 27 on one side will be in the wave groove 28 The wavy groove 28 can slide and move the cleaning brush 26 up and down, so that the handle 29 can continuously extend and retract in the rectangular groove inside the cleaning brush 26. The first limiting rod 25 and the second limiting rod 31 can limit the cleaning brush 26 and the handle 29. In this way, when the cleaning brush 26 moves along the direction of the first limiting rod 25, the cleaning brush 26 can also move in another direction, and brush the filter plate 5 up and down during translation, thereby increasing the movement form, and can clean the filter plate 5 in multiple ranges and angles, thereby improving the cleaning effect. In this way, the filter plate 5 at the bottom of the drying box 4 in the drying device can be efficiently cleaned through the above operation.

[0037] In specific implementation, when processing the LCD screen, it is necessary to clean its surface and then dry it through the drying device. When fixing the LCD screen, the drying rack 3 can be driven by the driving motor 2 to rotate to a position parallel to the ground, and then the LCD screen is placed on the bracket inside the drying rack 3. After placing it, the electric push rod 32 is started, and the electric push rod 32 can push the first movable plate 33 to move. When the first movable plate 33 moves, the first connecting rods 34 on both sides will pull the two sets of second movable plates 35 to move. When the two sets of second movable plates 35 move, they can also be moved by the second The connecting rod 36 pushes the third movable plate 37 to move, and the limiting column 38 will limit the first movable plate 33, the second movable plate 35 and the third movable plate 37. When the four groups of movable plates move synchronously, the limiting plates 39 on each side will gradually approach the LCD screen, and the limiting plates 39 will contact the frame of the LCD screen through the internal "V"-shaped rubber block 40 to flexibly limit the LCD screen. At this time, the drying rack 3 can be rotated to dry the internal LCD screen. In this way, the LCD screen in the drying device can be quickly limited through the above operations.
