[0028] The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] The utility model discloses a device for air drying a liquid crystal panel. Figure 1 to Figure 7 As shown, it includes a mounting plate 1. When the liquid crystal panel 22 is processed, it is necessary to clean and polish the liquid crystal panel 22. When the liquid crystal panel 22 is processed after cleaning and polishing, it is necessary to ensure that the surface of the liquid crystal panel 22 is dry. Therefore, a liquid crystal panel air-drying device is provided, which is used to air-dry the surface of the liquid crystal panel 22 after cleaning and polishing.

[0030] Ginseng Figure 2 to Figure 4As shown, a pair of mounting plates 1 are symmetrically provided, a plurality of first rollers 2 and second rollers 3 are installed between the pair of mounting plates 1, a first bearing 5 is installed on the side wall of the mounting plate 1, a first mounting shaft 8 is fixedly connected to the side wall of the first roller 2, the first mounting shaft 8 is installed in the first bearing 5, a second bearing 7 is movably connected to the side wall of the mounting plate 1, a second mounting shaft 9 is fixedly connected to the side wall of the second roller 3, and the second mounting shaft 9 is installed in the second bearing 7. After the liquid crystal panel 22 is cleaned and polished, it needs to be transported by a conveying device. A plurality of first rollers 2 and second rollers 3 are installed between the pair of mounting plates 1, and the first rollers 2 and second rollers 3 are correspondingly arranged so that the liquid crystal panel 22 can be driven to move by the driving of the first rollers 2 and the second rollers 3.

[0031] Further, Figure 6 As shown, in order to facilitate the installation of the first roller 2 and the second roller 3, a first bearing 5 is installed on the side wall of the mounting plate 1, and a first mounting shaft 8 is fixedly connected to the side wall of the first roller 2, and the first mounting shaft 8 is installed in the first bearing 5. The first mounting shaft 8 can be rotated under the action of the first bearing 5, and the first mounting shaft 8 can drive the first roller 2 to rotate when it rotates. A second bearing 7 is movably connected to the side wall of the mounting plate 1, and a second mounting shaft 9 is fixedly connected to the side wall of the second roller 3, and the second mounting shaft 9 is installed in the second bearing 7. The second bearing 7 can be used to rotate the second mounting shaft 9, and the second mounting shaft 9 can rotate when it rotates. Therefore, when in use, the first roller 2 and the second roller 3 can be driven by the driving device to rotate so as to transport the liquid crystal panel 22.

[0032] Ginseng Figure 6 As shown, a protective layer 4 is provided on the outer side of the first roller 2 and the second roller 3, and the distance between the lowest point of the protective layer 4 on the first roller 2 and the highest point of the protective layer 4 on the second roller 3 matches the thickness of the liquid crystal panel. Since the first roller 2 and the second roller 3 are used to transport the liquid crystal panel 22, and the liquid crystal panel 22 is a fragile product, in order to protect the surface of the liquid crystal panel 22 when the liquid crystal panel 22 is transported, a protective layer 4 is provided on the surface of the first roller 2 and the second roller 3. The protective layer 4 is made of a flexible material, and the protective layer 4 contacts the surface of the liquid crystal panel 22, so as to protect the liquid crystal panel 22 during transportation. And the distance between the lowest point of the protective layer 4 on the first roller 2 and the highest point of the protective layer 4 on the second roller 3 matches the thickness of the liquid crystal panel, so that the liquid crystal panel 22 can be driven to move by the rotation of the first roller 2 and the second roller 3.

[0033] Ginseng Figure 2 , Figure 3 and Figure 6As shown, a slide groove 6 is provided on the side wall of the mounting plate 1, the second bearing 7 is slidably connected in the slide groove 6, a support block 10 is fixedly connected on the lower side wall of the second bearing 7, a third bearing 11 is installed in the support block 10, a threaded rod 12 is threadedly connected on the lower side wall of the mounting plate 1, the upper end of the threaded rod 12 passes through the slide groove 6 and is sleeved on the third bearing 11, and a compression spring 13 is installed between the upper end of the second bearing 7 and the upper side wall of the slide groove 6. In order to facilitate the transportation of liquid crystal panels 22 of different thicknesses, the second roller 3 is set to be movable so as to adjust the distance between the first roller 2 and the second roller 3 according to the thickness of the liquid crystal panel 22. By providing a slide groove 6 on the side wall of the mounting plate 1, the second bearing 7 is slidably connected in the slide groove 6, so that the second bearing 7 can slide up and down in the slide groove 6, and then the second roller 3 can move up and down, so as to achieve the adjustment of the distance between the first roller 2 and the second roller 3.

[0034] Furthermore, since the stability of the second roller 3 needs to be ensured when in use, it is necessary to ensure the stability of the second roller 3 after adjustment. A support block 10 is fixedly connected to the lower end of the second bearing 7, and the side of the support block 10 in contact with the second bearing 7 is set to an arc shape that matches the second bearing 7, so that the support block 10 can stably support the second bearing 7. The side of the support block 10 away from the second bearing 7 is horizontally arranged, and a third bearing 11 is installed on this side. A threaded rod 12 is threadedly connected to the lower side wall of the mounting plate 1, and the upper end of the threaded rod 12 is passed through the slide groove 6 and installed in the third bearing 11. Since the threaded rod 12 can move up and down on the mounting plate 1 when the thread is rotated on the mounting plate 1, the threaded rod 12 can drive the third bearing 11 to move up and down when it moves up and down, so as to drive the support block 10 to move up and down, thereby driving the second bearing 7 to move up and down, and driving the second roller 3 to move up and down. The movement of the threaded rod 12 requires rotation, so the threaded rod 12 is required to drive the second roller 3 to move by the threaded rod 12. When the threaded rod 12 stops rotating, the lower end of the second roller 3 can be supported to stabilize the lower end. A compression spring 13 is installed between the upper end of the second bearing 7 and the upper side wall of the slide 6. Since the compression spring 13 has a downward elastic force on the second bearing 7, the upper end of the second roller 3 can be supported by the compression spring 13 to stabilize the upper end. Therefore, under the action of the threaded rod 12 and the compression spring 13, the second roller 3 can be stable when in use, and the position of the second roller 3 can be adjusted under the rotation of the threaded rod 12.

[0035] Ginseng Figure 1 and Figure 2As shown, a pair of air pipes 14 are installed between the mounting plates 1, and a plurality of nozzles 15 are installed on each of the pair of air pipes 14. When the liquid crystal panel 22 is transported by the first roller 2 and the second roller 3, in order to facilitate the cleaning of the moisture on the liquid crystal panel 22, a pair of air pipes 14 are installed between the mounting plates 1, and the pair of air pipes 14 are arranged at the upper and lower ends of the liquid crystal panel 22. When the liquid crystal panel 22 passes through the air pipes 14, the mounting plate 1 on the air pipes 14 will blow compressed air, and the moisture on the surface of the liquid crystal panel 22 is blown to the end of the liquid crystal panel 22 by the compressed air until it falls from the liquid crystal panel 22, so as to achieve the cleaning of the moisture on the surface of the liquid crystal panel 22.

[0036] Ginseng Figure 1 As shown, an interface 16 is provided at one end of the air delivery pipe 14, and the interface 16 passes through the mounting plate 1 and is placed on the outside of the mounting plate 1. The air delivery pipe 14 delivers compressed air to the nozzle 15, and the compressed air is sprayed out through the nozzle 15 to dry the moisture on the liquid crystal panel 22. An interface 16 is provided at one end of the air delivery pipe 14, and the interface 16 is connected to the compressed air pipe to deliver the compressed air to the air delivery pipe 14. And during delivery, the pressure of the compressed air needs to be adjusted according to the specific working conditions, so that the pressure of the compressed air can dry the moisture without damaging the surface of the liquid crystal panel 22.

[0037] Preferably, the plurality of nozzles 15 are all tilted, and the nozzles 15 on a pair of air pipes 14 are tilted symmetrically. In order to make the nozzles 15 have a better blowing effect on the liquid crystal panel 22, so as to ensure that the surface of the liquid crystal panel 22 can be air-dried, the nozzles 15 are tilted, and the tilt direction of the nozzles 15 is the opposite direction of the liquid crystal panel 22, so as to blow the moisture on the liquid crystal panel 22 to the end of the liquid crystal panel 22. And the nozzles 15 on the upper and lower air pipes 14 are symmetrically arranged, and the nozzles 15 at the upper end are tilted to blow downward, and the nozzles 15 at the upper end are tilted to blow upward, so as to complete the blowing of the upper and lower surfaces of the liquid crystal panel 22.

[0038] Ginseng Figure 2 and Figure 5As shown, a first baffle plate 17 is fixedly connected between the mounting plates 1, and a second baffle plate 18 is movably connected between the mounting plates 1, and the first baffle plate 17 is arranged above the second baffle plate 18. A protective cover 19 is installed on the side wall opposite to the first baffle plate 17 and the second baffle plate 18, and a groove body 20 is opened on the side wall of the second baffle plate 18 close to the mounting plate 1. A limiting screw 21 is threadedly connected to the side wall of the mounting plate 1, and the front end of the limiting screw 21 passes through the mounting plate 1 and is placed in the groove body 20. When the liquid crystal panel 22 is air-dried, in order to prevent the residual moisture on the liquid crystal panel 22 from entering the subsequent process, the first baffle plate 17 and the second baffle plate 18 are installed between the mounting plates 1, and the first baffle plate 17 and the second baffle plate 18 are respectively installed at the upper and lower ends of the liquid crystal panel 22, and are arranged on the rear side of the gas supply pipe 14. When the first baffle plate 17 and the second baffle plate 18 are used to process moisture, they need to contact the surface of the liquid crystal panel 22. In order to avoid damaging the surface of the liquid crystal panel 22 during the contact, a protective cover 19 is installed at one end on the opposite side of the first baffle plate 17 and the second baffle plate 18 so that the protective cover 19 can contact the surface of the liquid crystal panel 22, thereby protecting the surface of the liquid crystal panel 22.

[0039] Further, Figure 5 As shown, when the area of ​​the liquid crystal panel 22 after air drying passes through the first baffle plate 17 and the second baffle plate 18, the protective cover 19 will intercept the residual moisture on the upper and lower surfaces of the liquid crystal panel 22 so as to process the residual moisture. Since the position of the second roller 3 can be adjusted, when air drying liquid crystal panels 22 of different thicknesses, it is necessary to make the distance between the first baffle plate 17 and the second baffle plate 18 match the thickness of the liquid crystal panel 22. The second baffle plate 18 is movably connected between the mounting plates 1 so that the second baffle plate 18 can move up and down between the mounting plates 1. By opening a groove body 20 on the side wall of the second baffle plate 18, by threading a limiting screw 21 on the side wall of the mounting plate 1, the front end of the limiting screw 21 is passed through the groove body 20 and abutted against the side wall of the second baffle plate 18, so that the movement of the second baffle plate 18 between the mounting plates 1 can be limited by the limiting screw 21. Thereby, the movement and fixation of the second baffle plate 18 can be realized.

[0040] During use, when the liquid crystal panel 22 is cleaned and polished and then transported by the first roller 2 and the second roller 3, when the liquid crystal panel 22 passes through the air pipe 14, the nozzles 15 on the air pipe 14 on the upper and lower sides of the liquid crystal panel 22 will blow compressed air to the surface of the liquid crystal panel 22 so as to quickly dry the surface of the liquid crystal panel 22, so that the surface of the liquid crystal panel 22 is clean and dry after passing through the air pipe 14, so as to facilitate processing in subsequent steps.

[0041] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0042] The utility model provides an air drying device after the cleaning and polishing process of the liquid crystal panel. When the cleaned and polished liquid crystal panel is conveyed by rollers, the liquid crystal panel passes through a nozzle, and the compressed air sprayed from the nozzle can dry the residual moisture on the surface of the liquid crystal panel. Since nozzles are provided on both the upper and lower sides of the liquid crystal panel, the upper and lower surfaces of the liquid crystal panel can be air dried when the liquid crystal panel is conveyed, so that the surface of the liquid crystal panel is dry when the subsequent process is carried out.
