Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paint film thickness detection, in particular to a device for detecting the thickness of automobile paint surfaces. Background Art
[0002] Currently, to beautify and protect car bodies, cars are often sprayed with paint. In the field of automobile inspection, the thickness of the paint film can not only reflect whether the paint film is sprayed evenly and completely, but also whether the car body has been scratched or damaged, or whether the car body has been repaired by spraying. Therefore, measuring the paint film thickness is one of the more important inspection items in automobile quality inspection, especially in the quality inspection of recycled cars.
[0003] Most of the existing paint film meters are manually operated. The paint film meter is used to detect at various sampling points on the car to measure the average thickness of the paint surface. For the same car, the closer the paint thickness is, the more stable the overall car condition is. Sampling and testing at different positions of the car paint surface is relatively cumbersome and labor-intensive. In addition, some positions on the roof are difficult to reach manually, which reduces the detection efficiency. It is easy to cause hand shaking during use and the stability is poor. The thickness value of the car paint is small, which easily leads to a large difference in detection accuracy, increasing measurement errors and low reliability. Utility Model Content
