[0002] With the rapid development of deep space exploration and imaging systems, there is an urgent need for larger-aperture optical systems in observation and imaging systems to meet the requirements of people to see farther and more clearly. For this reason, humans have been constantly trying to improve the process level and break through the current processing limit to make the aperture of the prepared mirrors continuously increase to meet this urgent need. However, this also brings technical challenges to the manufacturing, processing, and coating of large-aperture mirrors.

[0003] For large-aperture mirrors, before coating, the mirror surface has to go through processes such as machining, grinding, and polishing. There are a large number of pollutants such as dust particles and polishing powders remaining on the mirror surface during the processing. It is necessary to effectively clean the substrate surface to remove dust and impurities on the substrate surface in order to improve the film quality and firmness and ensure a high reflectivity and durability of the film. In traditional cleaning processes, for mirrors with relatively small apertures, ultrasonic immersion cleaning and manual wiping methods can be used for treatment, and good cleaning effects can be achieved to meet the requirements of subsequent coating. However, when the mirror aperture is larger than 2m, the traditional cleaning process is not very suitable and it is difficult to meet the cleaning requirements and efficiency.

[0004] Based on the above problems, this application document proposes an automatic cleaning device for the coated surface of a silicon carbide mirror to improve the above problems. Summary of the Invention

[0023] Please refer to Figure 1-2 As shown, an automatic cleaning device for a coated surface of a silicon carbide mirror includes a fixed frame 1. The fixed frame 1 can be made of stainless steel. A cleaning chamber is provided inside the fixed frame. Corresponding limiting grooves 8 are respectively provided at the bottom and the top of the cleaning chamber. The inner wall of the limiting groove 8 is provided with a rubber pad to avoid damaging the surface of the mirror body 5. A spray pipe 6 and spray nozzles 7 are provided at the top of the cleaning chamber. The spray pipe 6 is connected to a water storage tank through a hose joint and a hose. Pure water is stored in the water storage tank and is sprayed for cleaning through a pump. The spray pressure is 0.2 - 0.5 MPa, and the spray flow rate is 8 - 15 L / min. Cleaning rollers 4 are provided on both sides of the cleaning chamber. Soft hairs for facilitating the cleaning of the surface of the mirror body 5 are provided on the side of the cleaning roller 4 facing the mirror body 5. The soft hairs can not only brush the mirror body 5 but also avoid damaging the mirror body 5. The cleaning roller 4 is connected to a motor 2 outside the cleaning chamber through a rotating shaft 3. When the cleaning roller 4 is driven by the motor 2 to rotate for cleaning the mirror body 5, its rotation speed is 50 - 60 r / min.

[0024] In a preferred embodiment, two groups of spray nozzles 7 are provided. The two groups of spray nozzles 7 respectively correspond to the two surfaces of the mirror body 5, and the angles of the spray nozzles 7 can be adjusted. The two surfaces of the mirror body 5 can be cleaned simultaneously through the two groups of spray nozzles 7, which not only improves the efficiency but also avoids the danger brought by flipping the mirror body 5. In order to improve the spray efficiency, the spray nozzles 7 can be designed to be adjustable within a range of 5 - 15 degrees for the spray angle.

[0025] In a preferred embodiment, the mirror body 5 is placed vertically in the cleaning chamber.
