Germany’s Leoni, best known for automotive cables, reports that it was won a contract from Volkswagen to equip 1,300 robots with its LSH 3 dresspack solution for production of electric vehicles.
A press release said that Leoni has already fitted a hundred of the robots at the VW Group’s production site in Zwickau. The LSH 3 provides the power for various bonding methods such as welding, handling, laser bonding, clinching and also adhesive bonding. The project also involves the installation of floor cable harnesses, i.e. installing the cabling for the robots or from the stationary tool to the robot control unit. Leoni notes that it has taken a holistic system approach, supporting customers with preventive maintenance, repairs and the adaptation of existing energy supply systems.
In the course of the next two years, several Volkswagen models are to be produced in Zwickau based on the new MEB platform, the release said. The Zwickau site will be dedicated solely to electromobility as of the end of 2020.
The robotics field has very high requirements to ensure mechanical, chemical and thermal product properties as there are challenges posed by powerful acceleration, compression and torsion, for example, as well as millions of flexing cycles. Further, resilience is a must for high temperatures, welding beads, oil and various chemicals.
Leoni’s LSH 3, which is highly reliable, compact and flexible in use, reduces the likelihood of a collision with interference contours. This advantage, combined with extremely resilient materials and tried-and-tested components, provides great freedom while at the same time allowing the dresspack to be ducted closely to the robot arm.
