Abstract

The invention discloses automatic positioning equipment for visual inspection of car body covering parts for solving the problems that the traditional manual detection speed is low, the precision is low and the detection range is narrow. The automatic positioning equipment comprises a base, a power device, an image acquisition device and a laser transmitter assembly, wherein the base comprises a base frame, an image acquisition system support and a laser transmitter assembly support, the lower ends of a camera height adjustment pole 1 and a camera height adjusting pole 2 of the image acquisition system support are fixedly connected with the base frame, the lower ends of a camera height adjustment pole 3 and a camera height adjusting pole 4 of the image acquisition system support are fixedly connected with the base frame, the lower ends of a laser height adjustment pole 1 and a laser height adjusting pole 2 of the laser transmitter assembly support are fixedly connected with the outer sides of a length control rod 1 and a length control rod 2 of the base frame, the power device is arranged on a power guide rail 1 and a power guide rail 2 of the base frame, the image acquisition device is arranged on the image acquisition system support and the laser transmitter assembly is arranged on the laser transmitter assembly support.

Description

technical field [0001] The invention relates to an automatic workpiece fixing device in the field of computer vision detection, more specifically, the invention relates to an automatic positioning device applied to the visual detection of the outer cover of an automobile body. Background technique [0002] As the main means of transportation for people's daily travel, automobiles are not only responsible for carrying functions, but also a handicraft that integrates art and beauty. The equipment and methods used in paint film quality inspection have a decisive effect on the accuracy and speed of car body paint film defect detection. [0003] refer to figure 1 , shown in the figure is the front view of a car door outer panel. At present, most of the car outer panels are detected by manual visual inspection, but manual inspection cannot accurately detect the small differences in car body paint film defects. In addition, the various types of paint film defects and the differen...
