Abstract

The invention discloses a plate detection method, device and system for a blanking line, and aims to solve the problems of low speed, low efficiency and low accuracy of manual testing. The plate detection method for the blanking line comprises the following steps: acquiring an image of a plate on the blanking line on line; processing the acquired plate image to obtain a to-be-detected plate pattern; and performing pattern comparison and measurement on the pattern of the to-be-measured plate. The problems that time and labor are wasted, efficiency is low and complete detection cannot be achieved in manual detection are solved, errors existing in manual observation and judgment are avoided, the precision of plate detection of the laser blanking production line is improved, and the qualified rate of machining is increased.

Description

technical field [0001] The invention relates to a sheet material detection method, device and system of a blanking line, and belongs to the technical field of visual recognition and measurement of metal processing technology. Background technique [0002] At present, the demand for steel plates in various industries is increasing, and the use of blanking lines is becoming more and more extensive. However, the quality inspection of the blanking line is all manual inspection, and the inspection accuracy also depends on the level of the inspection personnel. And this can't be done for all the current sheet metal inspections, only random inspections, and there is no way to find out the problems in time, resulting in a high scrap rate. [0003] In the laser uncoiling blanking production, whether the blanking sheet is qualified or whether there is a size error exceeding the standard, the laser head's own feedback is difficult to achieve this closed-loop control, so it is necessar...
