Description

Technical Field

[0001] This utility model belongs to the field of coating device technology, and in particular relates to a coating device for a stretchable self-healing hydrophobic coating of flexible electronic screens. Background Technology

[0002] Flexible electronic screens are display devices made from flexible materials (such as flexible plastics, metal foils, and ultra-thin glass). Compared with traditional rigid screens (such as LCD or OLED screens with glass substrates), they are bendable, foldable, and stretchable. Because flexible electronic screens are repeatedly bent and stretched during use, micro-cracks and scratches are prone to appear on the surface. Furthermore, flexible electronic screens are often used in wearable devices, outdoor displays, medical patches, and other scenarios, and are easily exposed to rain, sweat, and moisture. Therefore, a hydrophobic coating needs to be applied to the screen surface to provide waterproofing, moisture resistance, dust and dirt protection, and enhance mechanical durability.

[0003] Before applying a hydrophobic coating to a flexible electronic screen, it is necessary to remove contaminants such as dust, grease, and oxides from the screen surface to enhance the adhesion between the coating and the substrate. Then, the hydrophobic coating is atomized by a spray gun and evenly sprayed onto the surface of the flexible electronic screen. Finally, a drying device is used to allow the coating to cross-link and cure.

[0004] Typically, cleaning and coating operations for flexible electronic screens are performed separately, with a predetermined time interval between the two operations. However, flexible electronic screens are made of polymer materials, which are prone to electrostatic adsorption of particles from the environment. Furthermore, some workshop environments are not strictly controlled, so dust, oil, fibers, and other contaminants in the air can re-adhere to the screen surface after cleaning, affecting the coating quality. Therefore, a flexible electronic screen stretchable self-healing hydrophobic coating device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a flexible electronic screen stretchable self-healing hydrophobic coating application device to solve the problems mentioned in the background art.

[0007] A flexible electronic screen stretchable self-healing hydrophobic coating application device includes:

[0008] Workbench;

[0009] The main body of the device includes a cleaning plate, a mounting frame, a rotating plate, and a coating roller.

[0016] This invention comprises a main body consisting of a cleaning plate, a mounting frame, a rotating plate, and a coating roller. The cleaning plate is mounted on a workbench with its lower end face positioned at a predetermined distance from the upper end face of the workbench. An antistatic fiber material is provided on the lower end face of the cleaning plate near the workbench. The mounting frame is L-shaped, with its lower end fixed to the upper end face of the cleaning plate. The upper end of the rotating plate is rotatably mounted to the upper end of the mounting frame, and the coating roller is rotatably mounted to the lower end of the rotating plate.

The rotating plate has a limiting groove on its side wall near the abutment plate, and a limiting block is located at the upper end of the abutment plate, slidably inserted into the limiting groove. The worker can rotate the rotating screw, causing the abutment plate, which is rotatably connected to the rotating screw, to move closer to or further away from the mounting frame. At this time, the limiting block slides along the limiting groove, changing the angle between the rotating plate and the rotating screw. The rotating plate increases the distance between the coating roller and the flexible electronic screen. By using a rotating screw, the distance between the coating roller and the flexible electronic screen can be adjusted, thereby achieving precise control of the coating thickness and ensuring stable and uniform product performance. Furthermore, flexible materials of different specifications and thicknesses can be used, expanding the applicability of the equipment.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 4 As shown, this utility model embodiment provides a flexible electronic screen stretchable self-healing hydrophobic coating application device, including:

[0027] Workbench 1;

[0028] The main body of the device 2 includes a cleaning plate 21, a mounting frame 22, a rotating plate 23, and a coating roller 24. The cleaning plate 21 is mounted on the workbench 1, and the lower end of the cleaning plate 21 is spaced at a predetermined distance from the upper end of the workbench 1. The cleaning plate 21 is provided with antistatic fiber material on the lower end near the workbench 1. The mounting frame 22 is L-shaped, and the lower end of the mounting frame 22 is fixedly mounted on the upper end of the cleaning plate 21. The upper end of the rotating plate 23 is rotatably mounted on the upper end of the mounting frame 22. The coating roller 24 is rotatably mounted on the lower end of the rotating plate 23.

[0029] In this embodiment, during use, the worker first lays the flexible electronic screen to be coated flat on the upper surface of the workbench 1; then, the cleaning plate 21 is placed on the workbench 1 so that the fixing rod 11 is placed in the slide groove 211. At this time, the lower end surface of the cleaning plate 21 with antistatic fiber material is in contact with the upper end surface of the flexible electronic screen, and the rotating plate 23 is rotated until the circumferential side of the coating roller 24 is in contact with the upper end surface of the flexible electronic screen; the position of the cleaning plate 21 relative to the workbench 1 remains unchanged; the pulling or winding device slides the flexible electronic screen along the axial direction of the moving groove 12 and from the cleaning plate 21 toward the coating roller 24; during the sliding process of the flexible electronic screen, the flexible electronic screen is first cleaned by the lower end surface of the cleaning plate 21, and then, via the side of the coating roller 24, the sliding flexible electronic screen drives the coating roller 24 to rotate, and the rotating coating roller 24 evenly coats the coating on the surface of the flexible electronic screen; by setting the cleaning plate 21 and the coating roller 24, the cleaning and coating operations are carried out almost simultaneously, avoiding the flexible electronic screen being exposed to the air for a long time after cleaning and becoming contaminated with pollutants, thus ensuring the coating quality;

[0030] Specifically, the lower end faces of both ends of the cleaning plate 21 have grooves 211, and the opposite side walls of the workbench 1 are provided with fixing rods 11, which are adapted to the grooves 211.

[0031] Specifically, the workbench 1 has movable slots 12 on opposite side walls that are coaxial with the fixed rods 11. A pair of fixed rods 11 are placed between a pair of movable slots 12. The main body 2 of the device also includes a pair of movable blocks 25 and a pair of electric telescopic rods 26. The movable blocks 25 have insertion slots 251. The cleaning plate 21 has insertion blocks 212 on opposite side walls. The insertion blocks 212 are adapted to the insertion slots 251. Each movable block 25 is slidably placed in each movable slot 12. The two ends of the electric telescopic rods 26 are connected to the workbench 1 and the movable blocks 25.

[0032] In this embodiment, while the cleaning plate 21 is placed on the workbench 1, the insertion blocks 212 at both ends of the cleaning plate 21 are inserted into the insertion slots 251 on the moving block 25, at which point the flexible electronic screen is fixed on the workbench 1. Subsequently, the activated electric telescopic rod 26 drives the moving block 25 to slide along the moving groove 12, thereby driving the cleaning plate 21 to slide axially along the fixed rod 11. The sliding cleaning plate 21 first cleans the surface of the flexible electronic screen, and then, through the side of the coating roller 24, the rotating coating roller 24 evenly coats the surface of the flexible electronic screen with coating. In this way, by setting the cleaning plate 21 and the coating roller 24, the cleaning and coating operations are carried out almost simultaneously, avoiding the flexible electronic screen being exposed to the air for a long time after cleaning and becoming contaminated with pollutants, thus ensuring the coating quality.

[0033] Specifically, the rotating plate 23 is hollow, and multiple discharge holes 231 are spaced apart on one end face of the rotating plate 23 near the coating roller 24. A mist-making structure is installed inside the hollow rotating plate 23. The main body 2 of the device also includes a storage tank 27, which is mounted on the mounting frame 22. The storage tank 27 is connected to the rotating plate 23 through a hose.

[0034] In this embodiment, the paint in the storage tank 27 enters the interior of the rotating plate 23 through a hose and is made into mist by the mist-making structure inside the rotating plate 23. The mist is then sprayed onto the coating roller 24 through the discharge hole 231.

[0035] Specifically, the main body 2 of the device also includes a rotating screw 28 and an abutment plate 29. The side wall of the mounting bracket 22 has a threaded hole 221. The rotating screw 28 is threadedly connected to the threaded hole 221. One end of the rotating screw 28 is rotatably connected to the abutment plate 29. The abutment plate 29 is slidably mounted on the side wall of the rotating plate 23.

[0036] Specifically, the rotating plate 23 has a limiting groove 232 on the side wall near the abutting plate 29, and the upper end of the abutting plate 29 has a limiting block 291, which is slidably inserted into the limiting groove 232.

[0037] In this embodiment, the worker can rotate the rotating screw 28, which in turn drives the abutment plate 29, which is rotatably connected to the rotating screw 28, to move closer to or further away from the mounting frame 22. At this time, the limiting block 291 slides along the limiting groove 232, causing the included angle between the rotating plate 23 and the rotating screw 28 to change. The rotating plate 23 increases the distance between the coating roller 24 and the flexible electronic screen. By setting the rotating screw 28, the distance between the coating roller 24 and the flexible electronic screen can be adjusted, thereby achieving precise control of the coating thickness and ensuring stable and uniform product performance. In addition, flexible materials of different specifications and thicknesses can be used to expand the applicability of the equipment.

[0038] The working principle of this utility model is as follows:

[0039] When in use, the worker first lays the flexible electronic screen to be coated on the upper surface of the workbench 1; then the cleaning plate 21 is placed on the workbench 1 so that the fixing rod 11 is placed in the slide groove 211. At this time, the lower surface of the cleaning plate 21 with antistatic fiber material is in contact with the upper surface of the flexible electronic screen, and the rotating plate 23 is rotated until the circumferential side of the coating roller 24 is in contact with the upper surface of the flexible electronic screen.

[0040] In one embodiment, the cleaning plate 21 remains in a fixed position relative to the worktable 1; the pulling or winding device slides the flexible electronic screen along the axial direction of the moving groove 12 and from the cleaning plate 21 toward the coating roller 24; at the same time, the paint in the storage tank 27 enters the interior of the rotating plate 23 through the hose and is made into mist by the mist-making structure inside the rotating plate 23, and the mist is sprayed onto the coating roller 24 through the discharge hole 231; during the sliding process of the flexible electronic screen, the flexible electronic screen is first cleaned by the lower end face of the cleaning plate 21, and then passes through the side of the coating roller 24. The sliding flexible electronic screen drives the coating roller 24 to rotate, and the rotating coating roller 24 evenly coats the paint onto the surface of the flexible electronic screen.

[0041] In another embodiment, while the cleaning plate 21 is placed on the workbench 1, the insertion blocks 212 at both ends of the cleaning plate 21 are inserted into the insertion slots 251 on the conveyor block 25, at which point the flexible electronic screen is fixed on the workbench 1. At the same time, the paint in the storage tank 27 enters the interior of the rotating plate 23 through the hose and is made into mist by the mist-making structure inside the rotating plate 23. The mist is sprayed onto the coating roller 24 through the discharge hole 231. Subsequently, the electric telescopic rod 26, after being started, drives the conveyor block 25 to slide along the moving groove 12, thereby driving the cleaning plate 21 to slide axially along the fixed rod 11. The sliding cleaning plate 21 first cleans the surface of the flexible electronic screen, and then the rotating coating roller 24 evenly coats the surface of the flexible electronic screen through the side of the coating roller 24. In this way, by setting the cleaning plate 21 and the coating roller 24, the cleaning and coating operations are carried out almost simultaneously, avoiding the flexible electronic screen from being exposed to the air for a long time after cleaning and becoming contaminated with pollutants, thus ensuring the coating quality.

[0042] In addition, the worker can rotate the rotating screw 28, which in turn drives the abutment plate 29, which is rotatably connected to the rotating screw 28, to move closer to or further away from the mounting frame 22. At this time, the limiting block 291 slides along the limiting groove 232, which changes the angle between the rotating plate 23 and the rotating screw 28. The rotating plate 23 drives the distance between the coating roller 24 and the flexible electronic screen. By setting the rotating screw 28, the distance between the coating roller 24 and the flexible electronic screen can be adjusted, thereby achieving precise control of the coating thickness and ensuring stable and uniform product performance. In addition, flexible materials of different specifications and thicknesses can be used to expand the applicability of the equipment.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
