Description

Technical Field

[0001] The invention relates to the technical field of vehicle logo paint spraying, and in particular to a device for spraying acid-resistant paint for automobile logos. Background Art

[0002] As an important part of the vehicle's appearance, the car logo not only carries the function of displaying the brand image, but also needs to have good weather resistance and corrosion resistance. In order to protect the car logo from external environmental factors, such as ultraviolet rays, acid rain, etc., a layer of acid-resistant paint is usually applied to the surface of the car logo; due to the fixed spraying angle, it is difficult to ensure that the paint can evenly cover the entire surface of the car logo, especially for car logos with complex shapes or subtle concave and convex structures, so a spray gun is needed to complete the horizontal and vertical cross-spraying of the car logo to achieve the above-mentioned spraying effect.

[0003] Some existing spraying devices mostly use a group of spray guns to complete horizontal and vertical cross-spraying. A group of spray guns has to perform multiple spraying steps for each group of car logos, which is time-consuming and affects the conveying efficiency of the production line. In addition, when changing the spraying direction, extra time is required to adjust the position of the spray gun or wait for the car logo to rotate into place, resulting in low overall efficiency of the car logo spray coating production line.
