Patented by Schunk, the coupling of the gripping and rotation gear allows continuous rotation without an electric loop feed-through. Since the module is equipped with only stationary, brushless and non-wearing 24 V DC motors – and requires no moving cables, slip rings or shock absorbers – it provides increased process stability and availability in assembly systems. Backlash-free, pre-loaded junction roller guides ensure precision gripping and virtually constant gripping forces over the entire finger length, says Schunk.
Regarding commissioning of the unit, both the angle of rotation and the gripping force can be adjusted independently, directly at the module, while inductive proximity switches allow monitoring.
The module is either controlled digitally or via a fieldbus distributor. The entire control and power electronics for the motors is integrated directly into the module.
