Cool Tools: New OnRobot Screwdriver for cobots/robot arms

Automated precision assembly using cobots and robot arms just got easier with the introduction of an impressive new screwdriver unit from OnRobot.

The OnRobot Screwdriver allows manufacturers to automate a wide range of assembly processes quickly, simply, and flexibly. It provides a solid solution for manufacturers who are eager to automate repetitive, unergonomic, and often inconsistent manual screwdriving processes, but who struggle to integrate and program typical piecemeal screwdriving systems.

Programming the OnRobot Screwdriver is as easy as entering the appropriate screw length and torque value into the user interface that is integrated into the teach pendant of any leading 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 even detect incorrect screw length, which can help improve overall quality and reduce scrap.

With the screwdriver's unique "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. A screw feeder is available.

The OnRobot Screwdriver can handle a wide range of screw sizes and lengths, from M1.6 to M6, and up to 50 mm long. With its simple programming and easily exchangeable bit system, the smart unit can be changed over quickly to a different screw size, length, or product line in minutes, which minimizes downtime and improves productivity.

"This is one of our most advanced products to date," says Enrico Krog Iversen, CEO of OnRobot. "We've designed an automated screwdriving tool that simplifies a highly complex process for our users, making it cost effective and easy for manufacturers to see fast results in terms of higher uptime, output, consistency, and quality."

The OnRobot Screwdriver's feature set includes:

• Embedded axis for accuracy and easy programming;
• Precise torque control from 0.15 Nm to 5 Nm;
• Screw sizes from M1.6 to M6, and up to 50 mm long;
• Available screw feeders;
• ESD-safe for electronics assembly; and
• Mounting via OnRobot Quick Changer.

The screwdriver is compatible with OnRobot's award-winning One System Solution, a platform that provides a unified mechanical and electrical interface between leading robot arms and any OnRobot product.

With the OnRobot Quick Changer, a single cable provides a universal interface for tools and communications -- so there is no need to disconnect cables when changing tools. Extended communications options support a full range of robotic platforms.

The One System Solution has been newly expanded to include integration with robots from ABB Robotics and Hanwha Precision Machinery. Users of those robots can now also take advantage of the unified mechanical and electrical interface of any OnRobot product for easier integration and faster ROI.
