Screwdriver for robots from OnRobot

Multifunctional robot screwdriver with screw feeder


› Quick and easy set-up and changeover
› built-in protections
› embedded axis
› large selection of screw sizes and lengths
› accurate torque control
› ESD certified


With the new intelligent OnRobot screwdriver for light industrial, cooperation and assembly robot you can easily automate processes. Intelligent error detection and handling of multiple screw sizes ensures consistent results and drastically reduces your cycle time.

Seamless integration with the robot of your choice. For example Universal Robots, Nachi, Doosan, Yaskawa, TM Robot, Kawasaki, ABB, Kuka, Hanwha, Fanuc.

Due to the simple connection of the screwdriver and the operation and programming via the own URCap (only applies to Universal Robots) the grippers are ready for use in the shortest time.
In addition, the connection time is reduced by the OnRobot quick-change system Quick Changer and Dual Quick Changer.

Features of the Screwdriver
Automated bolting to increase productivity and quality has never been easier, smarter or more cost effective. The intelligent OnRobot screwdriver speeds setup and programming and gives you everything you need right out of the box. Simply mount the screwdriver on any assembly robot and install the appropriate bit, then enter screw length and torque directly into the robot’s user interface.

The precise torque control and embedded axis eliminate the time and cost of additional integration and ensure consistent, accurate screw insertion. Switching to a different screw type or size takes only minutes, reducing downtime and increasing ROI.

The OnRobot screwdriver and available screw feeders handle a wide range of screw sizes. This ranges from M1.6 to M6 and up to 50 mm in length. The precise torque control ranges from 0.15 Nm to 5 Nm. The OnRobot screwdriver is more versatile and intelligent than conventional tools. During the tightening process it detects whether the screw has been removed, is the correct length or has been inserted correctly.

The OnRobot screwdriver has protective functions that make it suitable for cooperative robot applications for screws up to 35 mm in length. During movement, the screws are fully retracted into the screwdriver.

The safety stop is automatically activated if a screw is subjected to excessive force along its axis. An alarm light indicates the problem.
