Visual automatic detection system and detection method thereof

Abstract

The invention relates to the technical field of automatic mechanical apparatuses, and concretely relates to a visual automatic detection system. The visual automatic detection system comprises a visual automatic detection device body (1), the device body (1) comprises a first camera (2) arranged at the upper part of the device body (1) and used for shooting, detecting and collating pictures of a bridge welding spot, the bottom of the device body (1) is provided with a lifting and rotating unit (3) for lifting and rotating a workpiece (9) to be detected, and the lifting and rotating unit (3) comprises a lower lifting cylinder (4) and an upper rotating platform (5). The detection method of the automatic visual inspection device has a higher detection efficiency than the prior art, and the detection device can automatically shoot and analyze the product and directly output a detection result without artificial intervention, so the defects of low efficiency and high misjudgement rate of traditional human eye detection are overcome in the invention.

Description

technical field [0001] The invention relates to the technical field of automatic mechanical equipment, in particular to a visual automatic detection system and a detection method thereof. Background technique [0002] With the development of society and the continuous progress of science and technology, coupled with the increasing consumption level, it will become a trend to use automation equipment to reduce labor intensity, improve product quality, and reduce risks in the manufacturing process. At present, the appearance and quality inspection of products are all detected by human eyes, because the judgment of human eyes is not easy to quantify and execute, human eyes are prone to fatigue, people are prone to emotional, and some high temperature or toxic environments cannot work for a long time, etc. Factors, resulting in the general misjudgment and misjudgment rate of the quality inspection of product appearance and shape.

Problems solved by technology

At present, the appearance and quality inspection of products are all detected by human eyes, because the judgment of human eyes is not easy to quantify and execute, human eyes are prone to fatigue, people are prone to emotional, and some high temperature or toxic environments cannot work for a long time, etc. Factors, resulting in the general misjudgment and misjudgment rate of product appearance and shape quality inspection are very high

Some places have tried to use cameras to obtain images to replace human eye detection, but they all manually put a single product directly on the workbench for photo inspection, take it away after inspection, and put a new one, so repeat, automation The degree is low, the detection efficiency is low, the work intensity of the detection personnel is high, and the detection accuracy is poor, which cannot meet the needs of modern high-speed automated production lines

[0003] The types and styles of automobiles are becoming more and more diverse. In the production process of existing generators, due to the large number of product models, parts will be mixed, missing, and assembled in the assembly process.

Detection by human eyes is inefficient, the standards are not uniform, and the detection results are difficult to guarantee; and long-term detection greatly increases the labor intensity of workers
