Description

Technical Field

[0001] The invention relates to the technical field of automobile spray painting, and more particularly to an automobile interior decoration spray painting system. Background Art

[0002] Automotive interior parts are affected by various factors during daily use, such as friction, light and temperature changes. The paint film formed after painting can improve the surface hardness, impact strength, wear resistance, heat resistance and cold resistance of the interior parts, thereby extending the service life of the interior parts and protecting them from direct influences of the surrounding environment. Painting can provide automotive interior parts with different colors and surface effects, such as high gloss, matte, metallic texture, etc., to meet consumers' demand for the aesthetics and personalization of automotive interiors, and enhance the overall quality and comfort of the car interior.

[0003] Local fixed-point spraying, by precisely controlling the trigger of the spray gun, sprays the paint briefly and accurately at a specific local position, so that the paint only covers the small area that needs to be treated. Its advantages are that it can retain the paint surface of the original interior parts to the greatest extent, reduce the impact on the surrounding areas, save paint, and has a good effect on repairing small defects; linear continuous spraying is that the paint is sprayed evenly onto the surface of the interior parts in a continuous linear form. This spraying method can achieve rapid spraying of a large area, form a uniform paint film, and improve work efficiency; at the same time, due to continuous spraying, the integrity and continuity of the paint film are better, and the appearance quality is higher.
