Abstract

The invention provides a deformed steel bar appearance defect detection device. The deformed steel bar appearance defect detection device comprises an image acquisition unit, two light sources, an image processing unit and a sound-light alarm unit;the image acquisition unit is used for acquiring an image of the surface of a deformed steel bar; the two light sources are used for reducing the influence of shadows and light reflection; the image processing unit is used for analyzing whether the appearance of the deformed steel bar has defects or not; and the sound-light alarm unit is used for giving an alarm when it is is analyzed that the appearance of the deformed steel bar has defects. The deformed steel bar appearance defect detection device provided by the invention has the advantages of being capable of automatically detecting appearance defects of deformed steel bars, replacing a manual screening process, being not limited by conditions such as experience of workers and labor intensity, and being high in detection efficiency and detection precision and good in stability.

Description

technical field [0001] The invention relates to the technical field of visual image detection, in particular to a detection device for appearance defects of threaded steel. Background technique [0002] Rebar is widely used in the construction of houses, bridges, roads and other civil engineering, ranging from highways, railways, bridges, culverts, tunnels, flood control, dams and other public facilities, to small foundations, beams, columns, walls, and boards of house construction. Rebar is an indispensable structural material. [0003] The appearance defects of rebar can be mainly divided into shape and size defects and surface defects. For size defects, if the relevant dimensions of the transverse ribs and longitudinal ribs do not meet the national standards, it is considered a substandard product; for surface defects, It mainly includes various defects such as convex hulls, pits, pits, etc. In the process of rebar rolling, due to the fast pace of production, once a pro...
