Four-Joint Hinge Assembly

The system is based on a rotary transfer machine with four process stations and a separate end-of-line test and labeling system (EOLT), and is fully enclosed to ensure safe, repeatable operation.

System Design and Functions

Manual assembly station with ergonomic parts feeding, illuminated work area, integrated control panel, and certified NIO tray.
An optional operator assistance system with laser projection is available, which projects assembly instructions directly onto the work surface and supports comprehensive placement verification. A two-hand start ensures maximum safety.

Flanging process using a high-performance servo press at a fixed position to ensure consistently high process stability.

Riveting station with a CNC cross table for performing multiple riveting processes. Integrated process monitoring (including lubrication, length measurement, and protrusion measurement) ensures the quality of the joints.

End-of-Line Testing and Laser Marking:
A handling robot retrieves the components, transfers them to testing and marking stations, and sorts them into transport containers.
The EOLT uses a multi-axis gantry to access any test position, including force/displacement measurement and geometric position checks.
Marking is performed using a fiber laser, which produces a high-contrast color change on the surface without damaging the coating. An extraction system ensures clean and safe working conditions.

The system combines ergonomic manual assembly, automated joining technologies, comprehensive quality inspection, and traceable component marking into a compact, scalable integrated system—designed for high process reliability and production readiness.
