Abstract

The invention discloses a copper foil defect detection system, which comprises: an acquisition module used for acquiring an initial image corresponding to a to-be-detected copper foil; a processing module, which is used for carrying out image preprocessing on the initial image to obtain a standard initial image; a matching module, which is used for carrying out contour matching on the standard initial image to obtain a detection image of the to-be-detected copper foil; a comparison module, which is used for generating a defect label associated with the to-be-detected copper foil on the basis that the difference coefficient of the detection image and a standard copper foil image is greater than a threshold value, extracting the detection image of the to-be-detected copper foil, and comparing the detection image with the standard copper foil image; in the detection process, the pixel unit of the detection image is used as the minimum comparison unit, so that the comparison speed can be increased, and the detection of the copper foils on the two sides can be completed in a short time.

Description

technical field [0001] The invention relates to a technique in the field of copper foil processing, in particular to a copper foil defect detection system. Background technique [0002] Copper foil is an important material for the manufacture of copper clad laminates, printed circuit boards, and lithium-ion batteries. With the rapid development of the electronic information industry, the demand for copper foil is increasing, especially high-quality copper foil. Therefore, it is very important to improve the quality of copper foil, especially the appearance quality seriously affects the service life and performance. [0003] At present, most of the detection of copper foil appearance defects at home and abroad rely on manual detection. Due to the large area of ​​copper foil, there are many types of defects and the characteristics are not obvious. Therefore, the detection results lack objectivity, low efficiency and labor intensity. Large; and due to the complexity of copper...
