Abstract

The invention discloses a laser vision locating correction method for a welding seam gap of an industrial robot. The method particularly comprises the following steps of respectively detecting S1 andS2 point position information on a first workpiece by using a sensor. The invention relates to the technical field of laser vision locating correction. Compared with a traditional laser vision weldingseam locating system, according to the laser vision locating correction method for the welding seam gap of the industrial robot, the laser vision sensor is used for detecting the welding seam gap onthe workpiece, different subprograms and welding processes are selected according to the size of the gap, when the workpiece is the first workpiece and the gap value S is smaller than A, a first welding program is called, a first process parameter is called, when the workpiece is a second workpiece and the gap value S is larger than A, a second welding program and a second process parameter are called, the number of welding passes and the number of layers can be judged automatically, the problem of welding defects caused by workpiece welding seam gap changes is solved, the production percent of pass can be effectively increased, and defective products are reduced.

Description

technical field [0001] The invention relates to the technical field of laser vision positioning correction, in particular to a laser vision positioning correction method for industrial robot welding weld seam gaps. Background technique [0002] Today's industrial production has higher and higher requirements for automation, and automation has become a trend in modern industrial production; automation adopts automatic control, automatic adjustment, detection, and processing machinery, equipment, and instruments, and automatically performs operations according to prescribed procedures or instructions. Technical measures are aimed at increasing production, improving quality, reducing costs and labor intensity, and ensuring production safety. The degree of automation has become one of the important symbols to measure the level of scientific, technological and economic development in a modern country. [0003] For the future welding process, on the one hand, it is necessary to de...
