OnRobot Screwdriver

OnRobot has released a screwdriver robot attachment designed to allow manufacturers to automate a wide range of assembly processes quickly, easily and flexibly.

Programming the OnRobot Screwdriver involves entering the appropriate screw length and torque value into the user interface that is integrated into the teach pendant of any typical robot. With precise torque control and embedded axis, the OnRobot Screwdriver automatically calculates the speed and force required for consistent, accurate screwdriving. The Screwdriver can detect incorrect screw length, which can help improve overall quality and reduce scrap. With the Screwdriver’s z-axis, screws are retracted inside the tool and driven automatically once the robot arm moves into position, which reduces robot arm movement and additional programming. Screws up to 35 mm long are retracted completely inside the Screwdriver when moving until the screwdriving process is safely initiated, enhancing its collaborative capabilities.

The Screwdriver can handle a wide range of screw sizes and lengths, from 1.6 to 6 mm diameter, and up to 50 mm long. With its simple programming and easily exchangeable bit system, the Screwdriver can be quickly changed over to a different screw size, length or product line in minutes, which minimises downtime and improves productivity.

Offering precise torque control from 0.15 to 5 Nm, the Screwdriver is compatible with OnRobot’s One System Solution, a platform that provides a unified mechanical and electrical interface between robot arms and any OnRobot device.
