Description

technical field [0001] The invention belongs to the technical field of scanning and cutting control systems in the steel material processing industry, and relates to a steel plate edge scanning and cutting control system based on a laser ranging sensor. Background technique [0002] The large-size (such as length, width and thickness: 33m*2m*15mm) steel plates produced by the rolling mill of the steelmaking plant are usually not regular rectangles, and their front, rear, left, and right edges have a certain degree of curvature, which needs to be cut off by a gantry flame plasma cutting machine The irregular part of the edge of the steel plate is cut into several small steel plates in the shape of "tofu block", which are used by downstream industries. Due to the large size of the steel plate produced by the rolling mill, at present, there is no suitable automatic detection system to identify its outline. The conventional two-dimensional outline recognition scheme can identify...

Problems solved by technology

Due to the large size of the steel plate produced by the rolling mill, at present, there is no suitable automatic detection system to identify its outline. The conventional two-dimensional outline recognition scheme can identify the outline of the steel plate. The structure of the two-dimensional outline recognition scheme includes wired laser, two-dimensional dimensional camera to take pictures, etc., but they can only recognize the outline of small-sized objects. Therefore, before the gantry flame plasma cutting machine cuts the steel plate, the edge of the steel plate can only be positioned manually by using measuring tools or by visual inspection. Cutting is time-consuming and labor-intensive and the cutting accuracy is low
