A local OEM customer was installing a new-model vehicle and planned robot guidance and nut runners to install the doors, lift gates, fenders, and hoods for the first time.
Diverse Automation worked with the auto manufacturer to develop the vision-guided robot programming standard that was used to install all hinges, doors, lift gates, fenders, and hoods, using a new process called Best Fit. Best Fit requires tightening and loosening of all hinges to the body and hinge to parts, as well as several separate vision fitting processes during the tightening and loosening of the parts. The system did more than put these parts on the car; it measured the openings and put the parts in the middle of the openings, because every car varied dimensionally.
The system included over $4 million in automated nut runners and vision equipment. Full traceability of bolting and fitting errors were developed, so if a problem arose, the line could continue to run, and the manual repair team downstream would know exactly which bolt or fitting process had an error, and what the specific error was.
