Abstract

According to the cold-rolled coil section bar code and defect detection device in the iron and steel industry, end detection intelligent robots are arranged on the two sides of operation and transmission near a saddle at a unit inlet, and the defect detection and size measurement functions of the end faces of the two sides of a steel coil can be completed on the two sides of the saddle at the same time. When end face defect detection is carried out, the tail end of the robot carries the three-dimensional sensor to carry out circular motion in the radius direction of the steel coil, and the three-dimensional contour surface type of the end face of the steel coil is obtained through the laser three-dimensional sensor. The sensor can output a scanning gray level image while scanning, and defects which cannot be determined by three-dimensional scanning are judged. The bar code and character recognition adopts a 10 million pixel industrial camera for imaging.

Description

technical field [0001] The invention relates to a barcode and defect detection device for cold-rolled coil sections in the iron and steel industry, and relates to the technical field of detection and identification. Background technique [0002] There are a large number of steel coils in the warehouse of a large steel factory. In order to facilitate the transportation, turnover, inventory management, and production control of the steel coils in the warehouse area, a labeling machine is often used to paste barcodes on the surface of the steel coils to identify the steel coil Reel number, size and other necessary information. In the detection stage or uncoiling stage of the steel coil, it is necessary to identify the barcode on the surface of the steel coil to verify whether the target coil is consistent with the information of the incoming coil in the production system. By comparing the barcode information with the incoming steel coil information, it is beneficial to timely ...
