AuCA - Automated Cable Assembly

Motivation

Handling and automated assembly of a wiring harness consisting of multiple cables with different lengths, cross-sections, and end contacts is extremely difficult for a robotic system to manage. For this reason, solutions typically involve a significant amount of cameras, software, and processing. In the AuCA system, cable laying has been completely rethought and combined with 3D printing technology, so that the flexible cables no longer need to be "gripped" but are laid from an endless reservoir

Technology description

The AuCA system consists of two tools (cable placement and contacting) that can be guided by collaborative robots. The end effector "Cable Deposition" enables cable feeding from an endless roll, automatic assembly, positioning, and mechanical attachment (thermoplastic extrusion) on the component. Up to 4 cables can be laid simultaneously. The end effector "Contacting" allows for independent gripping, stripping, crimping, and plugging of the laid cable ends into connector housings. The system has an automatic change option for crimp applicators, allowing different crimp elements from an endless roll to be attached according to DIN standards. This technology enables the flexible, fully automatic production of various wiring harnesses on the workpiece.

Wire Deposition

  • 450 x 500 x 660 mm; 18 kg, work at stationary points
  • Crimping tool head with certified standard crimping tools
  • Stripped wires are picked up from the part at the last fastening point and processed in the tool head
  • Crimping is force-controlled with an electric stroke cylinder
  • the crimped contacts can be inserted into connector housings in various orientations
  • several connector housings for different connections are stored in the tool head
  • the crimping tools can be changed automatically on a ramp within a workpiece
  • finished connector housings are placed on the workpiece
