OnRobot launches new gripper for handling cylindrical objects

OnRobot, the makers of robotics tools for collaborative applications, has released a compact, large-stroke three-finger gripper.

OnRobot says its 3FG15 makes previously hard-to-automate precision handling of cylindrical parts “easy to program and deploy, and provides flexibility for a wide range of part sizes”.

CEO of OnRobot, Enrico Krog Iversen, says: “Our new 3FG15 three-finger gripper was developed as a response to existing pneumatic three-finger grippers that are bulkier and less flexible.

“We have long defined the market for electric parallel grippers with the RG2 and RG6 series, and we look forward to addressing new market segments and applications with a new three-finger gripper that allows users to deploy applications faster even with highly accurate, fixed positioning.”

The 3FG15 gripper has a maximum stroke of 150 mm that can easily handle multiple processes. The innovative three-finger design with a 15 kg (33 lb) payload provides a strong, stable grip for both form fit (internal) or friction fit (external) gripping, adding flexibility to any implementation.

Suitable for CNC machine tending

The gripper’s design, specifically developed for machine-tending tasks, automatically centers workpieces, resulting in a strong, stable grip and precise placement in machine chucks. With a gripping force from 20 N to 250 N, the 3FG15 competes with much less flexible finger grippers.

OnRobot says the gripper is also “ideal” for packaging and palletizing applications, and is seamlessly compatible with any major collaborative or light industrial robot arm through OnRobot’s new One System Solution, the company’s platform that provides a unified mechanical and electrical interface between the robot arms and any OnRobot EoAT.

OnRobot says the 3FG15’s features include:

  • Precise stable grip with automatic centering
  • Large 150mm stroke for parts from 20 mm to 150 mm
  • Form fit (internal) and friction fit (external) gripping
  • 15 kg payload
  • Weight 1.15 kg, gripping force 20-240 N
  • Fast, flexible deployment
