Description

Technical Field

[0001] This utility model relates to the field of thin film coating technology, and in particular to a self-cleaning thin film coating device. Background Technology

[0002] Thin film coating refers to the process of depositing one or more layers of metal or dielectric thin film on the surface of a thin film. The purpose of coating the surface of a thin film is to improve the structural effect of the thin film. There are many ways to coat thin films. The most common method is spraying, which involves melting the material at high temperature and spraying it onto the surface of the substrate to form a coating. After cooling, the coating layer is formed.

[0003] During the coating process, the glass substrate needs to be continuously transported to the designated position. Then, the operator turns on the spraying switch to spray the molten material onto it. This process requires the operator to constantly observe and operate the equipment. If the operator makes a mistake, the coating will fail, which can result in serious losses. Therefore, a self-cleaning thin film coating device is proposed. Utility Model Content

[0012] Preferably, a bracket is fixedly installed on the top of the equipment base plate, the coating tank is installed on the bracket, and a top addition pipe is provided on the coating tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This self-cleaning thin film coating device places the glass substrate in the placement tank, starts the drive motor on the rotary drive assembly to drive the rotating shaft to rotate, thereby driving multiple placement plates to rotate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Refer to Figure 1-5 A self-cleaning thin film coating device includes a base plate 1, a coating tank 3 above the base plate 1, a heating box 5 above the base plate 1, and a pick-and-place port 6 on one side of the heating box 5. The material to be coated is placed in the coating tank 3 and heated to melt. A glass substrate is placed in a placement slot 11. The pick-and-place port 6 allows the operator to stand at the port to place and remove the glass substrate. A rotary drive assembly is located on the top of the base plate 1. The output end of the rotary drive assembly is connected to a rotating shaft 8. The top end of the rotating shaft 8 rotates through the heating box 5 and extends into the coating tank 3. Multiple placement plates 10 are fixedly installed on the rotating shaft 8 located in the heating box 5. A spraying assembly is installed on the coating tank 3 and extends into the heating box 5. A spraying trigger assembly is provided on the placement plate 10.

[0023] Preferably, the top of the placement plate 10 is provided with a placement groove 11, and one side of the placement groove 11 is open. The rotation drive assembly includes a drive motor 7 fixedly installed on the top of the equipment base plate 1. The output end of the drive motor 7 is fixedly connected to the bottom end of the rotation shaft 8. The spraying assembly includes a conveying pipe 13 installed on the coating tank 3. The bottom end of the conveying pipe 13 extends into the heating box 5. The conveying pipe 13 is arranged in an L-shape. Multiple atomizing nozzles 14 are provided at the bottom end of the conveying pipe 13. The spraying triggering assembly includes a component fixedly installed on the side of the conveying pipe 13. The mounting block 15 has a mounting box 16 fixedly mounted on one side. A pressing push rod 17 is movably mounted on the mounting box 16. An arc-shaped trigger head 19 is fixedly mounted on one end of the pressing push rod 17. An arc-shaped trigger block 12 is fixedly mounted on the top of the placement plate 10. The arc-shaped trigger block 12 is electrically connected to the arc-shaped trigger head 19. One end of the pressing push rod 17 extends into the mounting box 16. A pressing spring 18 is fixedly mounted between one end of the pressing push rod 17 and the inner wall of the mounting box 16. After the glass substrate is placed, the rotation drive assembly is activated. The drive motor 7 operates, causing the rotating shaft 8 to rotate, which in turn causes multiple placement plates 10 to rotate. During the rotation of the placement plates 10, the arc-shaped trigger block 12 of the spraying trigger assembly rotates and comes into contact with the arc-shaped trigger head 19, pressing against it. This pressing action moves the pressing push rod 17, thereby compressing the pressing spring 18. The pressing push rod 17 and the pressing spring 18 ensure that the arc-shaped trigger head 19 and the arc-shaped trigger block 12 have a certain pressing contact force, ensuring the stability of the contact. The arc-shaped trigger block 12 and the arc-shaped trigger head 19 are in contact with... Upon contact, the high-temperature melt pump inside the coating tank 3 is powered on and operates. The high-temperature melt pump can withstand high temperatures to ensure that the molten liquid is delivered. The delivered molten liquid is sprayed evenly onto the glass substrate through the atomizing nozzle 14 on the spraying assembly. It is slowly cooled in the heating box 5 to form a coating. The arc-shaped trigger head 19 and arc-shaped trigger block 12 are continuously rotated. After the placement plate 10 is delivered to the bottom, automatic spraying can be achieved without the need for manual operation of the switch by the staff, and precise spraying can be performed.

[0024] Preferably, a plurality of stirring rods 9 are installed on the rotating shaft 8 located inside the coating tank 3, and a bracket 2 is fixedly installed on the top of the equipment base plate 1. The coating tank 3 is installed on the bracket 2, and a top addition pipe 4 is provided on the coating tank 3. During the rotation, the rotating shaft 8 rotates and drives the plurality of stirring rods 9 to rotate, which can stir the solution inside the coating tank 3. Stirring can prevent the solution inside from cooling or condensing locally.

[0025] In this solution, a D263 glass substrate is used as the glass substrate, and a TiO2 base film layer is deposited on the glass substrate. D263 glass is selected as the substrate material because this substrate has excellent optical performance and mechanical strength, making it suitable for the high-end smart application market. By depositing a TiO2 base film layer on this substrate, high-performance self-cleaning filters can be prepared to meet the needs of high-end markets such as smartphones, automotive equipment applications, and smart TVs.

[0026] By introducing SiO2 into TiO2 for modification, the initial contact angle of the film surface can be effectively reduced, thereby improving the self-cleaning effect. This modification method can not only enhance the hydrophilicity of the film, but also improve its photocatalytic activity, enabling the self-cleaning glass to remove surface contaminants more effectively under light conditions.

[0027] By introducing polymer additives, such as polyethylene glycol, into the coating material, the porosity and roughness of the film surface can be increased during subsequent heat treatment. This structural increase helps to improve the hydrophilicity of the film, making it easier for water molecules to form a water film on the surface, thereby more effectively removing pollutants and achieving a self-cleaning effect.

[0028] In use: The glass substrate is placed in the placement slot 11, and the placement port 6 is provided for placing and removing the glass substrate. The drive motor 7 on the rotary drive assembly is started, which drives the rotating shaft 8 to rotate, thereby driving multiple placement plates 10 to rotate. During the rotation of the placement plates 10, the arc-shaped trigger block 12 of the spraying trigger assembly rotates and comes into contact with the arc-shaped trigger head 19 for compression. The high-temperature melt pump in the coating tank 3 is powered on and runs. The molten liquid delivered is evenly sprayed onto the glass substrate through the atomizing nozzle 14 on the spraying assembly. It is slowly cooled in the heating box 5 to form a coating. The arc-shaped trigger head 19 and the arc-shaped trigger block 12 are connected to the spraying mechanism. After continuous rotation, the placement plate 10 is conveyed to the bottom, enabling automatic spraying without the need for manual operation of the switch. It can spray precisely. During the rotation, the rotating shaft 8 drives multiple stirring rods 9 to rotate, which can stir the solution in the coating tank 3. Stirring avoids the problem of local cooling or condensation of the solution inside. By introducing polymer additives, such as polyethylene glycol, into the coating material, the porosity and roughness of the film surface can be increased during the subsequent heat treatment process. This structural increase helps to improve the hydrophilicity of the film, making it easier for water molecules to form a water film on the surface, thereby more effectively removing pollutants and achieving a self-cleaning effect.
