Description In case of an emergency, emergency-stops are crucial. Thus, quality has top priority for manufacturers. To be able to completely cover every safety-relevant parameter, the company Georg Schlegel has designed a fully automated test system. For 225 variants the robot is measuring the threads, the forcedistance ratio and the torque, a visual inspection is done simultaneously by cameras. Using the serial number, which the robot prints on automatically, and the inspection record, the result’s traceability is always guaranteed. With this innovation Schlegel has set quality standards and increased traceability. Furthermore, the profitability has been raised significantly thanks to the inspection volume of 450 buttons per hour.
