An automatic listing system and method

Abstract

This application discloses an automatic listing system and method. After the samples to be listed are packaged, the robot is controlled to move to the hollow area of ​​the sample to be listed, and the distance between the camera detected by the ranging sensor and the inner wall of the sample to be listed is received; When setting the distance, start the ring light source and camera, receive the first sample image taken by the camera; determine the packaging type and base point according to the first sample image; control the ring light source to turn off, start the structured light source, and receive the second sample image taken by the camera; According to the second sample image and the base point, calculate the best hanging point; control the movement of the robot, and hang the sign held by the grippers to the three-dimensional coordinates of the best hanging point; re-check the listing status, if the re-inspection result is listing failure , repeat the above steps until the listing is successful, and the re-inspection process ends. The application uses machine vision to automatically determine the best hanging point, and automatically executes the listing operation through the robot, which improves the listing efficiency.

Description

technical field [0001] The present application relates to the technical field of visual inspection, in particular to an automatic listing system and method. Background technique [0002] In the iron and steel industry, after being wound into coils, the steel wire rods currently produced on site are first transferred to the packing station through the hanging assembly line, automatically packed and bundled by multi-strand steel wires or steel strips, and then transferred to the weighing station, and the weighing is completed Afterwards, the printer prints the metal label in the manual operation table, and while waiting for the next finished coil to be weighed, the current coil operation is listed manually. When listing, take the label and the hook manually, first hang the label on the hook, and then hang the hook on different packaged steel wires or steel belts with a distance of about 300mm from the two ends of the inner coil of the wire coil, so as to complete the listing. ...

AI Technical Summary

Problems solved by technology

Since the assembly line is always in operation, the risk factor is high, and when the production volume of wire rod coils is large, manual running back and forth frequently and hanging signs, long-term work, high labor intensity, fatigue, and uncontrollable manual hanging signs There are inconsistencies in the suspension position (above or below) and the distance of the suspension, and manual long-term work is prone to the problem of hanging wrong signs and missing signs
