Flexible welding robot system and welding method thereof

Abstract

The invention discloses a flexible welding robot system and a welding method thereof. The welding method comprises the following steps: a global vision unit recognizes image information of a to-be-welded workpiece and locates the position of the to-be-welded workpiece; a flexible welding robot unit precisely recognizes the position of a to-be-welded workpiece through a precise positioning visual assembly, an image processing control machine solves a welding path, and the flexible welding robot conducts welding operation. A flexible detection robot unit recognizes the geometric dimension and quality of the appearance of a welded workpiece through a stereoscopic vision detection assembly, generates a welding quality report according to parameter information set by a user, and transmits a position with the welding deviation exceeding a threshold value and deviation value information to the flexible welding robot for repair welding. A master control unit executes image processing, data communication and motion control of the welding robot and the detection robot; and a workbench unit is used for quickly clamping different types of welding workpieces. The harm of welding operation to the body of a worker is avoided, and high flexibility and intelligence of the flexible welding robot system are achieved.

Description

technical field [0001] The invention belongs to the technical field of welding robots, and in particular relates to a flexible welding robot system and a welding method thereof. Background technique [0002] In the manufacturing industry, welding is one of the most commonly used connection methods between various workpieces. When welding the workpieces, the workpieces need to be positioned in advance. Due to the large differences in the shapes of different workpieces, the on-site workers need to cut materials for the workpieces. It is extremely inconvenient to use a large amount of teaching work, group pairing, and clamping position deviation. In addition, the existing welding operations often require workers to cooperate with manual operations, and a large amount of heat, radiation, and toxic gases will be generated during the welding process. The body of the worker causes relatively large injuries. Therefore, it is the future trend of the welding industry to use welding ro...
