Volkswagen installs first robot to collaborate directly with employees

30 August 2013

Volkswagen has installed its first robot to collaborate directly with employees in an engine production plant at Salzgitter, Germany

Odense (Denmark)/Salzgitter, August 29, 2013 - The car manufacturing group Volkswagen has integrated an industrial robotic arm from Danish manufacturer Universal Robots into mass production at its engine production plant in Salzgitter. The lightweight robot UR5 is installed in the cylinder head assembly section, where it is responsible for handling delicate glow plugs. What is special about this is that it is the first collaborative robot in use at Volkswagen worldwide. Due to its integrated safety mode the six-axis robotic arm is able to collaborate directly with people without any safety guards. It thus contributes significantly towards optimising healthy working processes.

The Volkswagen plant in Salzgitter, with an area of 2,800,000 square metres, is one of the largest engine production plants in the world. Some 6,000 employees manuacture approximately 7,000 petrol and diesel engines in over 370 variants there every day. The 3- to 16-cylinder engines are installed in the various models and brands of the Volkswagen group. The car manufacturer recently deployed a collaboative industrial robotic arm of the Danish manufacturer, Universal Robots, with people in the cylinder head assembly section of the plant for the purpose of insertng glow plugs into the cylinder heads.

By reason of its integrated safety mode (matching Standard EN ISO 10218), the industrial robot is able to work in the close vicinity of humans. It is equipped with a collaborative gripper, which the system integrator Faude Automatisierungstechnik has developed exclusively for Volkswagen and which meets the safety requirements of ISO/TS 15066, the specification standard for collaborating robots. Thus the robot was able to be integrated into the production line without additional protective housing.

‘We would like to enure an ergonomic workplace layout to benefit our employees in all areas of our company. By using robots without guards they can work together hand in hand with the robot. In this way, the robot becomes a production assistant in manufacture and as such can release staff from ergonomically unfavourable work’, explains Jürgen Häfner, project manager at Volkswagen’s Salzgitter plant.

The project was implemented over a period of two years in close collaboration with Universal Robots’ distributor partner Faude Automatisierungstechnik. Previously glow plugs had to be inserted manually in a stooping posture into difficult to view cylinder head drill holes.

This process has now been taken over by the six-axis UR5 lightweight robot from Universal Robots. It carefully picks up the delicate glow plugs, which are provided by a specially designed separation system, and puts them into the hard-to-reach drill holes. An employee is then responsible for tightening the glow plugs and for insulating the cylinder head, which is required for the next step in production. Thanks to the direct joint working with the robot, which acts as an assistant, he can carry out these activities in an upright, healthy posture. In doing so, he is able to keep a constant watch over the process, so as to be able to intervene quick-ly when necessary.

‘We are delighted with the successful implementation of this unprecedented project and with the fact that our robots can contribute towards ergonomic work processes,’ says Thomas Visti, Vice President and Chief Commercial Officer at Universal Robots.

‘This was able to be accomplished mainly due to the result-oriented and constructive cooperation between Volkswagen and our partner Faude Automatisierungstechnik.’
