Abstract

The invention discloses a plane material surface defect detection device which comprises a main body frame, a linear light source mounted on the main body frame and at least one detection module mounted on the main body frame, wherein the main body frame comprises two upright posts positioned on the two sides, and a crossbeam fixedly mounted on the two upright posts; a sliding guide rod is arranged on the crossbeam; the detection module comprises a mounting seat mounted on the sliding guide rod in a slide fit manner; a CCD image sensor and a point group type laser respectively positioned on the two sides of the crossbeam are mounted on the mounting seat; a linear light source mounting seat is respectively arranged on each of the two upright posts; two ends of the linear light source are respectively mounted on the two linear light source mounting seats; an adjusting mechanism used for adjusting the position of the linear light source in the direction perpendicular to the crossbeam is arranged between the linear light source mounting seats and the linear light source. The plane material surface defect detection device can realize defect detection of the surface of the plane material in a fully covering manner.

Description

technical field [0001] The invention belongs to the technical field of surface defect detection, and in particular relates to a detection device and a detection module for detecting surface defects of planar materials. Background technique [0002] In recent years, with the large-scale introduction and transformation of semi-automatic and fully automatic production lines, coupled with the gradual advancement of school-enterprise cooperation and the strong support of local policies, the production and preparation process of flat materials has been injected with fresh blood of science and technology, and the product quality has been improved. greatly improved. But in terms of quality monitoring and management, because it not only cannot be directly used to improve productivity, but also reduces the yield of products, the development of related automation and intelligent monitoring and management equipment is very slow. Especially in the aspect of surface defect detection, alm...
