n PRECISION ENGINEERING production line,” says supply chain manager, Jan Schwarzwälder. “To this end, we integrate quality assurance into several sub-steps. We fully document the quality produced, of course, and can guarantee traceability on an individual part basis.” Each connector is subjected to a mating force test, in which specified tolerances must be met precisely. Any missing or duplicate components are detected. At the end of the line, a camera-based final inspection takes place. “To keep cycle times to a minimum, we have equipped the station where the pass/fail parts inspection takes place with two modules,”Wiech explains. “A camera system measures the inner diameter and checks the number of pins on the Multilam.” At this station, the completed parts are handled by one of the six-axis robots, whose dynamic operation ensures compliance with the tight cycle time. When products need to be changed over, the processes are optimised down to the last detail. “Depending on the complexity of the end-product, the changeover time varies from two to a maximum of 20 minutes,” says Schwarzwälder. To help achieve this, an MPS 025 robotic tool-changer from Stäubli Fluid Connectors is used, operating with a precision of ±1.5μm and eliminating the need for time-consuming manual changes. Currently, the line is producing seven variants for use in e-mobility and welding automation applications. Further variants will follow. Similarly, the integration of an automated packaging line is planned. “That’s the beauty of this pioneering system,” says John Dallapiccola. “Thanks to its immense flexibility, we are no longer subject to any restrictions. We can produce any number of variants and integrate further processes as required. The synergy effects of Stäubli’s Robotics, Fluid and Electrical Connectors business units have played a major role in the realisation of this unique assembly plant.” n While the CombiTac connector ensures the simultaneous connection of all energy and media circuits, a quick-release coupling ensures the correct fit of the module on the assembly line. A four-axis Scara robot with a small footprint is used for duties such as fitting socket rings
