OnRobot launches ‘intelligent screwdriver’ for collaborative robots

OnRobot, the maker of tools for collaborative robots, has released a screwdriver end-effector for collaborative robots. (See video below.)

OnRobot says its “smart, complete-out-of-the-box” Screwdriver allows manufacturers to automate a wide range of assembly processes quickly, easily, and flexibly.

The company says this provides welcome relief 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 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 35mm 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 1.6mm to 6mm diameter, and up to 50mm 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 minimizes downtime and improves productivity.

Enrico Krog Iversen, CEO of OnRobot, says: “This is one of our most advanced products to date.

“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 includes the following features:

  • embedded axis for accuracy and easy programming;
  • precise torque control from 0.15 Nm to 5 Nm;
  • screw sizes from 1.6mm to 6mm diameter, and up to 50mm 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.

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 return on investment.
