A control method of a robot for detecting and remediating spraying on the inner surface of an automobile

Abstract

The invention provides a control method of a robot for detecting and remediating spraying on the inner surface of an automobile. The invention is used to detect and fill the interior of the automobile frame. The invention quickly and accurately identifies the type of the target vehicle frame through the identification information provided on the target vehicle frame. The present invention generates the second three-dimensional contour model through the first three-dimensional contour model inside the target vehicle frame and the first spraying data information, so as to facilitate manual or robot general judgment on the internal spraying condition of the target vehicle frame after spraying. The present invention obtains the pictures of each spraying area, and the shooting range of the picture is slightly larger than the range of the corresponding spraying area, so that it is convenient to accurately extract the outline of the spraying area from the picture, and at the same time, it reduces other spraying areas when the shooting range is too large. Excessive shooting into the target picture causes errors in the range and color recognition of the sprayed area, which improves the accuracy of detection.

Description

technical field [0001] The invention relates to the field of automatic control of intelligent machines, in particular to a control method of a robot for detecting and remediating spraying on the inner surface of an automobile. Background technique [0002] After the end of the Cold War, a large number of spraying processes and equipment were converted to civilian use. In order to pursue greater flexibility and higher efficiency in the spraying process, the automobile industry began to introduce robots to replace spraying machines from the 1990s, and at the same time began to use robots. Automatic spraying of the inner surface instead of manual spraying. As a result, a variety of spraying processing lines composed of intelligent robots have emerged. [0003] At present, the spraying process plays a key role in some devices such as refrigerators and automobiles. Different spray paints play an important role in improving temperature resistance, corrosion resistance, and aesthe...

Problems solved by technology

[0005] However, in the actual spraying process, especially for some privately customized vehicles, since there are many spraying areas on the outer surface and the inner surface, and each spraying area also needs to be sprayed with patterns of different colors, even a spraying robot It is also often prone to leaks or mis-sprays

At the same time, the inner surface of the car is difficult to detect due to problems such as the angle of light and the narrow space.

However, manual detection is time-consuming and labor-intensive, and the existing machine detection often has the problem of missed detection.
