Abstract

The invention discloses a wire rod section shape defect detection system and a detection method thereof, comprising: a light source unit for projecting light sources at different angles on the wire rod cross section; and a projection area for receiving the projection of the wire rod cross section diameter by the light source unit Imaging; an acquisition unit, configured to acquire a projected imaging image formed by the projection area; a calculation unit, configured to receive and calculate and process the image acquired by the acquisition unit. The invention can not only monitor the interface size and shape changes in the wire production process online, but also monitor the abnormal surface profile of the wire surface through the shape difference, and provide a quality accident prevention method for the online safe production of the wire.

Description

technical field [0001] The invention relates to the field of wire rod production quality monitoring and control, and more particularly, to a wire rod cross-sectional shape defect detection system and a detection method thereof. Background technique [0002] In the production process of wire rods such as steel wire and copper wire, the diameter of the wire rod is a key indicator of wire rod production. The measurement of the wire rod diameter can not only monitor the diameter of the product to avoid the production of out-of-tolerance products, but also have a dimensional effect on the surface of the wire rod. Unusual defects are also monitored for defects such as wear, inclusions, and lead entrapment. In the production process of wire rod, not only need to pay attention to the diameter of the wire rod, but also some surface defects will occur during the processing process, some of which are not only reflected in the difference in appearance and color, but also have abnormal c...
