Detection method and system for material surface detects of wide-range high-speed production line

Abstract

The invention provides a detection method and a detection system for material surface defects of a wide-range high-speed production line. The system comprises image acquiring equipment, image processing equipment and system lighting equipment, wherein the image acquiring equipment is used for acquiring the information of the original image of the material surface of the production line; the image processing equipment is used for processing the original image information acquired by the image acquiring equipment; and the system lighting equipment is used for providing the imaging light to the image acquiring equipment. The detection system provided by the invention is conveniently arranged on the production line of a productive material without requiring changing the conventional production process, thus the real-time online detection on the production material surface can be realized, and the production efficiency of the manufacturer is improved; and the system is high in detection precision, low in omission factor, low in production cost, and capable of releasing lots of manpower as well as improving the industrial automation level of a plant.

Description

technical field [0001] The invention relates to the fields of machine vision detection and industrial automation, in particular to a method and system for detecting surface defects of materials in a wide-format high-speed production line. Background technique [0002] At present, many manufacturers of wide-format high-speed production lines in China mainly rely on the naked eye recognition of workers or detection after cutting for the detection of material surface defects. However, due to the subjective factors of limited people, the situation of missed detection often occurs during the detection process, which brings great economic losses to the manufacturer. Moreover, with the continuous increase of labor costs and the continuous increase of production line speed, this purely manual detection method is becoming less and less desirable. [0003] To sum up, the existing wide-format high-speed production line surface inspection technology has the following deficiencies: [...

AI Technical Summary

Problems solved by technology

[0004] 1. High missed detection rate: Subjective factors of limited people, the probability of missed detection in the material testing process is very high;

[0005] 2. High cost: the missed detection rate is high, and the manufacturer will suffer a large economic loss; moreover, with the increase of workers' wages, the labor cost of the manufacturer will also become higher and higher;

[0006] 3. Low detection accuracy: relying solely on manual detection, the detection accuracy is bound to be very low;

[0007] 4. Low production efficiency: manual inspection restricts the increase of production line speed
