The defects in the prior art can be overcome, and the welding seam quality detection speed is increased.

Description

technical field [0001] The invention relates to the technical field of automatic welding, in particular to an automatic welding machine based on machine vision and a control method thereof. Background technique [0002] Automatic welding is a welding technology that has developed rapidly in recent years. It can effectively replace manual welding in some fields, save manpower and improve work efficiency. By introducing machine vision technology into the field of automatic welding, it is possible to realize the automatic inspection of welding quality by automatic welding equipment. However, the existing machine vision technology needs to perform complex calculation processing on the weld image when detecting the weld, which consumes a long time and has poor real-time monitoring of welding quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic welding machine based on machine vision and its control m...
