Abstract

The invention provides a full-automatic laser welding method and a full-automatic laser welding device. The method is divided into a preparatory stage and a welding stage. The preparatory stage comprises the following steps: storing track information of to-be-welded welding seams into a computer; marking any one or multiple positions in a pick-up head photographing range which includes a to-be-welded region; setting a welding seam search region based on marks by taking the marks as reference. The welding stage comprises the following steps: collecting image information; searching the mark quantity and position information in images; performing linear detection to obtain the position and angle information of the welding seams and finally generating the actual position and outline tracks of the welding seams. The method can be used for realizing full-automatic laser welding, not only is automatic welding of straight welding seams realized, but also the automatic welding of random welding seam tracks such as circular arcs and curves is realized, to-be-welded workpieces are positioned without fixtures, multiple workpieces on the top of a workbench can be randomly placed each time and automatic welding is realized; track welding can be realized without special mechanical parts.

Description

technical field [0001] The invention relates to the field of automatic production and processing, in particular to the field of fully automatic laser welding of any straight line or curve and its combined trajectory, specifically a fully automatic laser welding method and device. Background technique [0002] Laser welding technology is widely used in industrial electronics, automobile manufacturing, aerospace and other fields, and is an efficient, high-precision, and highly reliable connection method. In order to improve welding efficiency and quality consistency, some fully automatic laser welding methods have been developed. From the retrieved information, there are two basic technologies utilized by the fully automatic laser welding method, the first is based on image recognition technology, and the second is based on automatic fixtures. [0003] The Shenyang Institute of Automation of the Chinese Academy of Sciences and Japan's IHI Corporation jointly developed a laser...
