Thin steel plate narrow welding joint online visual inspection and control device

Abstract

The invention discloses a thin steel plate narrow welding joint online visual inspection and control device which comprises three major modules including a welding joint image collection module, an image processing module and a control module based on visual feedback information. The welding joint image collection module is connected with the image processing module through a USB (universal serial bus) interface line, and the image processing module is connected with the control module based on the visual feedback information through a standard industrial bus. The thin steel plate narrow welding joint online visual inspection and control device can overcome the defect that existing welding joint tracking task forms are relatively unitary, can be used for multi-welding-machine concentrated visual detection and control of narrow welding joints of thin steel plates on a production line, and has the advantages of simple structure, stability in working, high detection accuracy, good control effect and the like.

Description

technical field [0001] The invention relates to thin steel plate welding technology, in particular to an on-line visual detection and control device for narrow weld seams of thin steel plates. Background technique [0002] Welding quality of thin-plate butt narrow welds is critical. However, welding of thin steel sheets with narrow seams is currently performed almost entirely by hand. During the welding process, the welder constantly observes the position of the welding torch and the welding seam, and constantly manually adjusts the position of the machine head so that the welding torch is centered on the welding seam. Manual welding often leads to two problems: one is that human visual limitations can cause inaccurate seam tracking, and repair welding is often required after welding; the other is that workers need to observe the deviation between the welding torch and the seam in real time , according to the tracking effect manual correction in real time. Apparently, thi...
