New 2-Finger Parallel Grippers from SCHUNK

New 2-Finger Parallel Grippers from SCHUNK

Added to MTDCNC by MTDCNC on 10 July 2013

Versatile, sensitive and extremely simple – this is the best description of the WSG series of servo-electric 2-Finger Parallel Grippers from SCHUNK. The competence leader for clamping technology and gripping systems has designed the new mechanical grippers for handling and assembly processes, where high flexibility or sensitivity are required. A whole range of possibilities for achieving more efficiency in production automation is hidden under its simple appearance. SCHUNK has significantly expanded the series with a long-stroke version and a compact small parts gripper.

The WSG is convincing in many aspects. There is a long, flexibly definable stroke that allows alternated and reliable handling of different components with a gripping force that can be precisely controlled via the power supply. Moreover, the gripper is the first one of its kind that incorporates an integrated gripped part detection and an integrated gripping force control system.

Via standardized sensor interfaces in the base jaws (UART, SPI and analog), sensors are directly integrated into the gripping process without any additional cabling or interfering contours. By using the optionally available force-measuring fingers type ABF WSG050-DV from SCHUNK, forces that occur upon the gripped component, can be precisely recorded and controlled to allow the process-reliable handling of fragile components. But the WSG can also score in terms of dynamics and precision. It has specially developed belt kinematics that ensure high chuck jaw speeds that reduce cycle times at a long stroke. The compact WSG32 achieves gripping speeds of 400mm/s. Since the detection of the gripped component is already integrated in the WSG and is not monitored via attached end position switches, the gripper itself achieves a high positional accuracy.

Intuitive operation – minimum programming effort

In view of the comprehensive possibilities offered by the WSG, it is more surprising how easy the talented gripper can be programmed via the intuitive configuration. Without having to install any software, it can be quickly and easily commissioned via Ethernet TCP/IP through a conventional web browser that is integrated as standard in the gripper. Moreover, it can also be used for remote diagnosis and for sending out status e-mails. Since many common operations are already deposited in the unit as intelligent gripping commands, the programming effort is reduced to a minimum.

On request, the range of functions can be individually adjusted to the application by using the integrated, and easy to learn script language. This allows even complex tasks to be solved reliably and easily. The issued script can be stored on a MicroSD card, which can also be used for updates or replicating configuration data for other grippers.

Three variants are available

The WSG is available in three variants: As WSG 50, it can be controlled via Ethernet TCP/IP, Profibus, CAN-Bus, RS232 or via eight virtual digital I/Os. For simplifying commissioning via Profibus, an additional Profibus monitor is integrated.

In addition to the basic version, the WSG 050-110 with a stroke of 55mm per finger, there is a long-stroke type, the WSG 050-210 with a stroke of 110mm per finger. Both grippers achieve gripping forces between 5N and 120N. The WSG 32 however, is very compact and has been particularly designed for handling small parts. Via an Ethernet connection, it is directly network-compatible and on option, it can be equipped with a CAN-Bus interface. Its stroke per finger amounts to 34mm, and the gripping force ranges between 5N and 50N.
