Background
At present, the paint spraying on the surface of the automobile mostly adopts an atomizer electrostatic spraying mode. In the spraying process, a certain flow of compressed air can form a complete and uniform spraying sector after flowing through the air ring component of the atomizer, so that the uniformity of a paint film sprayed on a vehicle body is ensured. Since the paint mist cannot be completely absorbed by the vehicle body during the spraying process, about 20% of the paint can be rebounded to the atomizer by the vehicle body to pollute and block part of holes in the air ring. The condition that the spraying sector is incomplete can occur when the polluted and blocked air ring is used, so that the thickness of paint film is uneven, paint is less in partial area, and the consequence that the partial area is sagging again causes a great deal of waste due to vehicle reworking. To avoid this, air ring cleaning and fan integrity testing are critical to controlling the quality of the coating.
At present, no particularly effective method is available for cleaning the air ring, and the cleaning is mainly realized by a light transmission method and a method for dredging a through needle. The test method mainly comprises the following steps: and (3) irradiating the hole from one side of the air ring by using a manual electric light, observing whether the other side has light transmitted out, if no light exists, indicating that the blockage of the hole needs to be dredged, and then dredging by using a through needle.
