[0002] The structure of an LCD is to place liquid crystals between two parallel pieces of glass. There are many thin vertical and horizontal wires between the two pieces of glass. By energizing or not, it controls the rod-shaped crystal molecules to change directions, refracts light to generate an image. When an LCD screen is produced, its composite screen board needs to be subjected to glue coating processing.

[0003] Traditional glue coating equipment mostly adsorbs glue by a glue roller, and then rolls back and forth on the screen to apply glue. However, during actual operation, when the glue coating equipment needs to stop for a long time or after the glue coating is completed, the glue roller needs to be cleaned to prevent the glue remaining on the glue roller from sticking to impurities and dust and drying out, generating additional accumulations and crusts. Conventional glue coating equipment generally sets the glue roller in a detachable manner. When cleaning is required, the glue roller is disassembled, cleaned, and then reinstalled. Such an operation is rather troublesome and the labor cost is relatively high.

[0004] Therefore, it is necessary to design a glue coating device for the outer surface of an LCD screen that can be quickly cleaned. Content of the Utility Model

Detailed implementation mode

[0020] The following specifically introduces the present utility model in conjunction with the attached drawings and specific embodiments.

[0021] Embodiment 1

[0022] As Figure 1 and Figure 2 shown, the present utility model provides a glue - applying device for the outer surface of an LCD screen, which specifically includes a workbench 1, a glue - applying assembly 2, a driving rod 3, a first gear 4, a first rotating brush 5, a driven rod 6, a second gear 7, a second rotating brush 8 and a handwheel 9;

[0023] Among them, a glue - applying assembly 2 is arranged on the top of the workbench 1. The glue - applying assembly 2 includes a glue - applying roller, a glue tank and an electric push rod, and is used for applying glue to the LCD screen;

[0024] Among them, circular grooves are symmetrically and rotatably penetrated through the front side of the inner wall of the workbench 1. A driving rod 3 is rotatably arranged in one of the circular grooves. One end of the driving rod 3 is rotatably in contact with the groove of the inner wall of the workbench 1. A first gear 4 is fixedly arranged on the driving rod 3 near the inner wall of the workbench 1. A first rotating brush 5 is fixedly arranged at the central position of the driving rod 3 close to the roller. The width of the first rotating brush 5 is greater than that of the roller. A driven rod 6 is rotatably arranged in the other circular groove. A second gear 7 is fixedly arranged on the driven rod 6. The second gear 7 meshes with the first gear 4. A second rotating brush 8 is fixedly arranged at the central position of the driven rod 6 close to the roller. A handwheel 9 is fixedly arranged at the outer end of the driving rod 3 and is used for cleaning the glue - applying roller.

[0025] In the present utility model, the staff can clean the used glue - applying roller. First, the staff use the electric push rod to lower the glue - applying roller between the first rotating brush 5 and the second rotating brush 8. Subsequently, the staff rotate the handwheel 9, so that the handwheel 9 drives the driving rod 3 to rotate. The driving rod 3 drives the first rotating brush 5 to rotate to clean the glue - applying roller. In addition, since the first gear 4 meshes with the second gear 7, the first gear drives the second gear 7 to rotate in the reverse direction. The driven rod 6 fixedly matched with the second gear 7 rotates in the reverse direction, and the second rotating brush 8 located on the driven rod 6 and the first rotating brush 5 located on the driving rod 3 clean together. In this way, it is ensured that after the staff use the glue - applying device, they can complete the cleaning operation of the glue - applying roller without disassembling the glue - applying roller, which is convenient for the staff to operate and continuous glue - applying operation.

[0026] Example 2

[0027] As Figures 2 to 5 shown, on the basis of Example 1, it specifically further includes a helical gear part 11. At the lower left and right sides of the rear side of the inner wall of the workbench 1, fixing grooves 10 are symmetrically opened. One end of the helical gear part 11 is in snap-fit with the fixing groove 10, and the other end is arranged in the groove opened in the workbench 1. The bottom surface of the helical gear part 11 is slightly higher than the bottom surface of the workbench 1; a plug pin 12 is slidably arranged between the helical gear part 11 and the groove.

[0028] A helical gear part 11 is arranged below the first rotating brush 5 and the second rotating brush 8. When the burrs of the first rotating brush 5 and the second rotating brush 8 carry glue and rotate to the lower part, they pass through the helical teeth on the helical gear part 11, and then the glue on the burrs is scraped off by the helical teeth on the helical gear part 11. When too much glue accumulates on the helical gear part 11 and needs to be replaced and cleaned, the staff only needs to slide the plug pin 12 so that the plug pin 12 leaves the hole in the helical gear part 11, and then one end of the helical gear part 11 can be removed. Since the other end is in snap-fit with the fixing groove 10, it can be directly slid out. In this way, the helical gear part 11 can be replaced when needed, and in this way, the functions of the first rotating brush 5 and the second rotating brush 8 will not be affected.

[0029] It further includes a collector 14. First sliding grooves 13 are symmetrically and fixedly arranged on the left and right sides of the bottom surface of the workbench 1, and the collector 14 is slidably arranged between the two first sliding grooves 13.

[0030] The collector 14 is slidably arranged between the two second sliding grooves 15, and can collect the waste generated by cleaning the glue application roller. By sliding the collector 14 out of the first sliding groove 13, it is convenient for the staff to discharge the waste.

[0031] As Figure 1 shown, on the basis of Example 1, it specifically further includes a top cover 16. Second sliding grooves 15 are symmetrically opened at the front and rear of the concave part of the tabletop of the workbench 1, and the top cover 16 is slidably arranged between the two second sliding grooves 15.

[0032] The top cover 16 is slidably arranged between the two first sliding grooves 13. When the cleaning function is not used, the sliding cover slides to the upper part of the first rotating brush 5 and the second rotating brush 8. When the glue application device applies glue, if there is glue dripping, the glue will dry on the first rotating brush 5 and the second rotating brush 8. When the cleaning function needs to be used, the top cover 16 can be slid open. In addition, since the surface position of the top cover 16 is lower than the bottom surface position of the LCD fixture, even if there is glue dripping onto the top cover 16, it will not affect the use of the fixture.

[0033] As Figure 2 shown, on the basis of Example 1, it specifically further includes a splash guard 17. The splash guard 17 is arranged outside the upper part of the first rotating brush 5 and the second rotating brush 8 in the workbench 1.

[0034] The splash guard 17 is located outside the first rotating brush 5 and the second rotating brush 8 to block the glue flying out when the first rotating brush 5 and the second rotating brush 8 rotate.

[0035] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
