TASK

Robot-assisted X-ray inspection of vehicle locking systems

Kiekert is the world’s biggest manufacturer of automotive locking systems. At its largest plant in Prelouc, Czech Republic, a workforce of some 2,400 produces around 180,000 side door latches a day on 60 assembly lines.

Among the numerous automated assembly and testing tasks involved is the 100% inspection of soldered connections. A high-precision Stäubli robot has the job of manipulating the latches as they pass through a compact X-ray inspection cell.

The latest development in the design of these locking systems is the incorporation of convenience functions such as Kiekert’s proprietary Kiekert “Soft-Close” mechanism. As with all motor vehicle locks, the zero-defect principle applies. Consequently, the production engineers at Prelouc sought a way to subject th
