The portfolio includes ergonomic handheld screwdrivers for manual use as well as stationary screwdriving tools for easy integration into automated PLC-controlled systems. Tools with EC servo technology ensure flexibility. Integrated sensor-controlled torque and rotation angle measurement enables precise control and regulation of screw tightening. Free programmability of the applications, documentation and evaluation options for process parameters as well as accuracy and safety in the process sequence are further features. Brushless EC motors ensure maintenance-free operation. Depending on the application, EC motors with torque measurement based on current consumption and pneumatically operated screwdrivers are also available. All screwdrivers are available in a straight design, angled design for confined spaces or with a pistol grip for horizontal use. Depending on the tool and requirements, you can work with torques from 0.008 to 500 Newton meters. The DFM feed module can even be used to fasten screws in hard-to-reach places; screws or nuts are held in place on the screwdriver by a vacuum until they are processed.

Various feeding technologies are available depending on the requirements for technical cleanliness or noise levels. High conveying speeds and high output rates can be achieved with vibratory bowl feeders, also known as vibratory conveyors. If low-wear, low-noise conveying that is gentle on components is required, a segment or lifting rail conveyor is used. The parts to be conveyed in the storage container are threaded by the swivel movement of a segment-shaped lifting rail and slide by gravity into the separator. This feeding system is suitable for applications with high demands on technical cleanliness.

Linear feeders are possible links between the feeder and the screwdriving tool. Like vibratory bowl feeders, they work according to the micro-throw principle and are used when larger distances need to be bridged in the assembly system, part buffers need to be provided or the flow of parts needs to be pulled apart. As the linear feeder conveys the parts faster than the feeder provides them, the components can be safely removed by grippers.

Preferably, the fasteners are fed directly from the feed system into the screwdriving unit via a feed hose. For screws with a short shank, rivets with a large collar diameter or parts with complex external geometries, a hose feed is often not possible; in this case, the pick-and-place method is ideal, with which the screws are "picked" using a vacuum, gripper system or magnetism. pb
