Robotic screwing unit SEV

modularvacuumelectronically controlled

Product overview
The fixtured screwdriver SEV enables process-reliable screwdriving at recessed and hard-to-reach locations. Closed construction and wear-resistant surfaces extend service life and maintenance intervals even during dry running without oil. Available with pneumatic drive or EC motor; suitable for automatic feeding and for shank-heavy screws.

Key features

• Screwdriving spindle with vacuum technology for access to recessed and deep screw locations
• Compatible with automatic feeding systems (feeding during screwdriving / swivel arm principle)
• Automatic feeding for screws and pins
• Suitable for interference contours up to 150 mm
• Modular design for flexible configuration
• Pneumatic or electric (EC) drive options
• Designed for shank-heavy screws and technical cleanliness (particulate reduction)
• Vacuum bit and vacuum module for screw fixation during feeding
• Swivel arm option for short cycle times

Customer-provided drives
The open system design of the SEV allows integration of customer-provided drives and controllers, facilitating installation into existing assembly lines. Subsequent conversion to WEBER components is possible.
