Abstract

The invention relates to a 3D weld seam scanning system based on weld seam 3D shape detection. The 3D weld seam scanning system comprises a welding robot. The welding robot comprises a welding gun anda camera. The welding robot is connected with a master control module. The master control module is used for receiving and analyzing images shot by the camera and transmitting an instruction to the welding gun. The master control module determines the material of a welding rod in a first weld seam area and then determining the welding mode and the weld seam standard of the first weld seam area according to the materials of a first workpiece to be welded and a second workpiece to be welded. Different welding modes and weld seam standards correspond to the preset weld seam shape. By comparing and judging the width difference value zk and the height difference value zh formed according to the actual weld seam shape of the first weld seam area and the preset weld seam shape, the material of awelding rod and the welding mode in a next weld seam area are adjusted, so that the actual weld seam shape of the weld seam area is in line with the preset shape.

Description

technical field [0001] The invention relates to the field of welding seam detection of robotic automatic welding seam, in particular to a 3D welding seam scanning system based on three-dimensional shape detection of welding seam. Background technique [0002] In recent years, with the vigorous development of the manufacturing industry, increasing the productivity of welding production, ensuring product quality, and realizing the automation and intelligence of welding production have attracted more and more attention from welding production enterprises. The integration of modern intelligent control technology, digital information processing technology, image processing and sensor technology, high-performance CPU chip and other modern high-tech has made great progress in modern welding technology. [0003] In welding, the shortcomings of manual welding are mainly reflected in the uneven welding level of workers, and the quality of products is difficult to guarantee. In additio...
