Automatic body welding spot eddy current inspect system

DESCRIPTION

1、Finished welded body in white, transported to the inspection platform, in place
2、At this time, the 4-arm robot controlled by PLC enters the working mode at the same time
3、After the solder joint position teaching robot, according to the user set the solder joint quickly position
4、The PLC activates the vision device located on the front detection module of the robot
5、The visual device checks the position of the target solder joint, and transmits the position signal after the check to the robot
6、The robot sends the probe mounted on the most front end of the inspection module to the target solder joint 40mm
7、The probe, driven by compressed air, accurately locates the target solder joint
8、The vortex coil on the probe detects the weld core and sends the signal back to the controller located on the robot
9、After analyzing and calculating the detection signal by the controller, the detection results are fed back to the PLC in the form of numbers and curves
10、The PLC forms the inspection report and feeds the results back to the welding system
