Automatic screw insertion and fastening using a collaborative robot

Streamlining model maintenance.

As part of a model update (facelift), this project involved giving front frame assemblies a redesign. WEBER adapted an assembly line with an end-of-line test station, integrating an automatic screw-setting unit with a collaborative robot (cobot) at one of the workstations.

Human-robot cooperation
Technical  description
  • Automatic screwing of components – for consistent assembly quality
  • Gripping and positioning of the screwdriver – via gripper system on the UR10 cobot
  • Screwdriving process – with force-controlled feed from the cobot
  • Freely configurable screwing sequence and screw programs – for flexible adaptation to different variants
  • Placing down the screwdriver and repositioning components – as part of the automated workflow
  • Connection to host computer system – for higher-level process control
  • Storage of screwdriving data – in the host computer system
  • Cycle time – 30 seconds
