Abstract:In order to realize the automation of welding tag on the end face of bundled round steel,an automatic tag welding system was designed based on industrial robot,guided by binocular vision measurement.The whole system was mainly composed of industrial robot,binocular vision recognition system,welding nail supplying system,tag preparation system,end-effector and control system.In the binocular recognition system,a binocular camera was used to scan the end face of bundled round steel in three dimensions,to obtain the welding position coordinate.The welding nail supplying system realized the distribution and transmission of welding nails,and the tag preparation system could realize the information preparation of tags.Driven by the industrial robot,the end-effector could grasp welding nail,hold tag,position and break welding nail.The industrial computer established communication with the robot,PLC and binocular vision measurement system,etc.So the automatic process of welding tag is realized.
