Spraying apparatus for highly uniform coating of space electric field detector, and spraying method thereof

Abstract

The invention provides a spraying apparatus for highly uniform coating of a space electric field detector. The apparatus can realize highly uniform spraying of the surface coating of the electric field detector, and includes a spraying gun, a mechanical arm, a homogenization plate, a support bar, a bearing (6), a bearing mounting support, a motor, a motor mounting support and a baseboard; and the homogenization plate is arranged between the spraying gun and the electric field detector, and the shape of the opening of the homogenization plate is arranged to make the spraying gun uniformly spray the coating on the electric field detector. The structure of the spraying apparatus is simple and can be easily realized; and the concentration of the coating, the height of the spraying gun, the discharging speed of the spraying gun, a distance between the homogenization plate and the spraying gun, and a distance between the homogenization plate and the electric field detector can be fixed, and the surface spraying uniformity of the electric field detector can be guaranteed by changing the shape of the opening of the homogenization plate, so the spraying apparatus has the advantages of stable process, good repeatability and high quality coating, and is also suitable for the coating spraying of other crafts with rotational symmetry.

AI Technical Summary

Problems solved by technology

[0003] The uniformity of the sensor surface coating (DAF 213) of the space electric field detector has a great influence on the measurement accuracy. It is difficult to achieve uniform spraying by manual spraying, and the manual spraying process is unstable, and there is no consistency between different sensors. Therefore, a process-stable spraying method is required to achieve uniform spraying
