Abstract

The invention relates to an on-line detection system and method for internal defects of a cold-rolled aluminum alloy plate strip. Internal defects are displayed and stored in time while on-line detection and plate strip conveying are carried out synchronously, the plate strip conveying efficiency is not affected, conveying equipment is not damaged, and meanwhile the internal defect detection efficiency is improved. A detection strategy is determined according to matching of a plate strip scanning graph and a plate strip model in a material library, so that the plate strip internal defect detection efficiency is further improved; the plate strip and each piece of detection equipment are adjusted according to a display result, so that internal defects of the plate can be more conveniently and intuitively known, the detection efficiency is further improved, and the plate quality is improved; the third detection equipment and the fourth detection equipment synchronously and preferentially detect the plate strip, and for an aluminum alloy plate strip with the rectangular section, the internal defects of the plate strip can be detected in the direction parallel to the width direction of the plate strip, and meanwhile, the smoothness defects easily existing on the top surface and the bottom surface of the plate strip can be preferentially detected.

Description

technical field

[0001] The invention relates to the technical field of defect detection of cold-rolled aluminum alloy strips, in particular to an on-line detection system and method for internal defects of cold-rolled aluminum alloy strips. Background technique

[0002] In recent years, due to various advantages such as conductivity, ductility, ease of production, low cost, and high efficiency, the production method of aluminum alloy plate, strip, and foil production to provide high-quality blanks has been widely used in related industries. With the improvement of quality and process requirements for downstream products, the quality requirements for aluminum alloy strips are also getting higher and higher. Therefore, it is necessary to detect internal defects of strips in time and make corresponding corrections during the production process. However, in the existing In the testing process, one of the schemes is to set a sampling inspection port at the conveying outlet of the...
