SCHUNK has launched a compact, mechatronic 24V gripper for small components, allowing flexible processes during a fast-paced pick and place operation. The SCHUNK EGB with IO-link, based on the tried-and-tested SCHUNK EGP, scores with a high speed and high gripping force, satisfies the IO-Link Class B Standard suitable for increased power consumption, and can be directly connected with an IO-Link Class B Master. Its gripper fingers can be freely positioned within every cycle, providing the highest level of flexibility.
Due to the gripper’s pre-positioning, the shortest cycle times can be ensured. As the gripping force can be adapted to the respective workpiece using software settings in four stages, handling scenarios with deformation-sensitive parts can also be achieved. Within the permissible finger length, both the gripping force and the gripping speed remain virtually constant over the entire stroke. The position of the gripper fingers is detectable using the integrated measuring system over the entire stroke, and no external sensors are required for monitoring.
On the other hand, intermediate positions or varying workpiece sizes can be monitored at any time. An integrated diagnosis tool permanently monitors the voltage, current, temperature, and condition of the gripper, and transmits errors automatically to the superior control system. If needs be, systems operators can also store maintenance intervals for the system on the tool. As the entire electronics of the SCHUNK EGP is space-saving in its interior, the gripper doesn’t take up any space at all in the control cabinet. Brushless servomotors and a clearance-free junction roller guide ensure a high level of efficiency, constant gripping forces across the entire finger length and make the SCHUNK EGP with IO-Link a dynamic, precise, and powerful expert for challenging handling of small and mid-sized parts.
Just like its predecessor the pneumatic SCHUNK MPG-plus, SCHUNK EGP takes screws on the side or at the base, increasing its flexibility within a system design. In order to increase the dynamics and the energy efficiency of higher-level systems, the gripper housing consists of a special high-performance aluminium. In addition, the design is rigorous in eliminating superfluous materials. It fulfils protection class IP30 and is suitable for the most various applications in the area of small component handling and assembly. SCHUNK EGP will initially be available in sizes 40, 60, and 64 with a finger stroke of 6/8/10mm, and maximum gripping forces of 140N/210N/300N. The repeat accuracy during the gripping operation amounts to 0.02mm, and during positioning of the gripper fingers, it amounts to 0.1mm to 0.2mm. However, this depends on the fact whether the finger position is reached from one or two directions. The gripper is suitable for handling parts up to 0.7kg/1.05kg/1.25kg. In addition to the version with IO-link, the 24V gripper is again available with actuation via digital I/O.
