Vision inspection of NOX holder with thread gauging
System can inspect different models of NOX holders. The system uses cameras to inspect all external measurements of the piece size and the minimum diameter of the internal thread. The centricity of the inner hole is inspected and the absence of shavings in the thread is checked. The edges and surfaces of each piece are also checked. If the piece meets all the criteria, the robot transfers it to the gauging station where we automatically gauge the GO calibre to a certain depth. When gauging, we measure the torque, maximum torque, average torque, gauge depth, number of steps, and thread clearance.
