Automatic screwing unit SER/SEB

modularelectronically controlledfor screw assembly

Overview
The SER and SEB fixtured screwdrivers are modular, industrial screwdriving units supplied with automatic screw feeding. SER provides a screwdriver stroke with external feeding via slide or robot; SEB integrates the feed stroke. Both are designed for fully automated assembly processes with short cycle times and easy integration into automation cells.

Flexible drive concept
Both models support pneumatic drives and electronically controlled EC motors. EC motors can be fitted with a dynamic transducer for torque and angle measurement; an optional redundant transducer is available for safety-critical (category A) applications in accordance with VDI/VDE 2862. The modular drive concept enables selection of the appropriate drive and sensor package for the application.

Flexible drive modules
Quick reconfiguration between drive modules and heads reduces downtime. Units are suitable for mounting on Cartesian axes, robots or swivel-arm feeders. Configurable bit strokes and tool holding couplers adapt the screwdriver to a wide range of fastener types and assembly geometries.
