Schunk GmbH last week released its EGL-C long-stroke gripper, which it said “represents a milestone in the road to achieving comprehensive human-robot collaboration.” The gripper is designed to achieve high gripping forces while complying with global safety standards.

The company claimed that the EGL-C is the world’s first long-stroke gripper for collaborative operation. It achieves high gripping forces up to 450 N, combined with a long stroke of 42.5 mm per finger.

智能24V动力室适用于处理高达2.25千克的工件砝码，并可用于各种应用中，说明Schunk。作为额外的加点，该组件将由DGUV认证，用于在2019年底的市场推出及时的人员机器人协作（HRC）应用。

While the gripping force of the DGUV-certifiedSchunk夹子迄今为止已限制为每根手指140 n公司现在正在上升to a new league of components with the Co-act EGL-C. For the first time, it said, HRC will be opened up with the potential for handling weights beyond small parts assembly.

The gripping and clamping technology leader said it is focusing its attention primarily on the automotive-related supplier industry, as well as the automotive manufacturers themselves, since they are working intensively on HRC scenarios.

此外，Schunk共同行动团队的专家还将专注于其他工业应用，如机械工程。强大的夹具可能成为HRC应用的有效加速器，由于在载荷范围内没有可靠的致动器，因此预先是不可能的。

Combining measurements for safety

为了遵守所定义的生物力学精确限制ISO / TS 15066尽管其高夹持力，但Schunk Co-Act EGL-C夹具配备了组合的力和位移测量。在基础钳口中集成的力测量钳口和增量编码器永久地监测相应的夹持力以及夹持器手指的位置。

据解释Schunk。Up to a theoretical distance of 4 mm to the taught workpiece, which is much less than the thickness of a finger, the gripping force is limited to 30 N.

如果在该方法期间发生碰撞，则例如，与操作者的手接触，夹具立即呈现牢固的保持，没有受伤的风险。

It is only in the second phase, such as with a workpiece distance of less than 4 mm, that the fingers close with the user-definable maximum force of up to 450 N. If the system measures flexibility in this closing phase, for example, because a workpiece is being gripped that is too small and the operator wants to remove it by hand, then this motion will also stop automatically. The same applies if the workpiece dimensions expected are exceeded by 2 mm due to reasons such as the absence of a part.

在第三阶段，robotic gripperthen detects whether the part has been safely gripped and then activates the integrated maintenance of gripping force by clamping the brake. That means that the gripped part can never be dropped, even in the event of an emergency shutdown. In addition, no referencing is required in the event of a power failure.

Plug & Work for Co-act EGL-C

The powerful long-stroke gripper from the Schunk Co-act series is delivered completely preassembled and is available with the corresponding interfaces for HRC robots, including those from FANUC, KUKA, Nachi, Universal Robots, and Yaskawa, enabling fast and simple commissioning via Plug & Work. A commissioning wizard simplifies the programming process.

In addition, a diagnosis interface allows access to the most important process and status data of the gripper during operation. To make collaboration with the user smooth and intuitive, the gripper is equipped with LED traffic light colored lighting which can be used to signal the appropriate status of the module.

The intelligent Schunk Co-act EGL-C can be optionally controlled and operated via PROFINET, EtherCAT, EtherNet/IP, Modbus/TCP or TCP/IP. As a space-saving solution, the complete control and regulation electronics are installed inside the housing, making decentralized use possible. Due to its 24 V DC operating voltage, the gripper can also be used in mobile applications.
