Ceramic surface defect detection device and method

Abstract

The invention relates to the technical field of ceramic defect detection, and particularly discloses a ceramic surface defect detection device and a ceramic surface defect detection method. The ceramic surface defect detection device comprises a light source, an image collector and a data processor, wherein the light source is located above to-be-detected ceramic and sample ceramic, and is used for generating light and irradiating the to-be-detected ceramic or the sample ceramic; the image collector is positioned above the to-be-detected ceramic and the sample ceramic, and is used for collecting an image of the sample ceramic under light irradiation and collecting an image of the to-be-detected ceramic under light irradiation; and the data processor is electrically connected with the imagecollector, and is used for acquiring the image of the sample ceramic as a sample image, acquiring the image of the ceramic to be detected as a detection image and calculating and extracting a defectpart in the detection image according to the sample image. The ceramic surface defect detection device and the ceramic surface defect detection method have the advantages of low cost, very low misjudgment probability and very low missed detection possibility.

Description

technical field [0001] The invention relates to the technical field of ceramic defect detection, in particular to a ceramic surface defect detection device and detection method. Background technique [0002] With the development of society and the improvement of people's living standards, people's pursuit of material has also increased. The unique luster and beauty of ceramic products are more and more sought after and loved by people. At the same time, people have higher and higher requirements for the quality of ceramic products. Usually, after the ceramic products are produced, the surface of some finished products has defects such as scratches, glaze cracks, chipped edges, missing corners, caves, pits, bumps, etc., and these products often cannot meet people's use requirements, so These defective products need to be screened out by some method. At present, the most commonly used method in ceramic factories is the visual inspection method, that is, an assembly line is e...

Problems solved by technology

At present, the most commonly used method in ceramic factories is the visual inspection method, that is, an assembly line is equipped with 2-4 people for manual defect inspection. The assembly line generally works 24 hours a day and requires 2-3 shifts. The labor cost of manual inspection is high and misjudgment High probability, high possibility of missed detection, etc.
