Denso Robotics launches new scara robot

Denso Robotics has launched its latest HSR four-axis scara – selective compliant assembly robot arm – robot. 

The company says the new robot uses advanced vibration control, a newly designed, highly rigid lightweight arm and improved heat dissipation in the base unit to achieve new levels of continuous high-speed performance and repeatability.

Peter Cavallo, robotics sales manager, Denso products and services Americas, says: “Our new HSR robot represents the culmination of 50 years of experience in developing industrial robot arms to meet our own manufacturing needs in the highly competitive automotive sector. 

“What sets the HSR apart is that it can run at its maximum speed and maintain its highest repeatability without interruption, not just in short bursts. That translates into more cycles per minute, which in turn means higher throughput.”

Reduced shaft whip and settling time, along with a lighter-weight arm and an optimized arm structure, make the HSR more efficient than previous models, enabling it to accelerate faster, run continuously at its highest rated speed and stop more precisely.

Denso says standard cycle time (with a 2-kg weight) of the HSR robot is from 0.28 to 0.31 sec. and repeatability is from ±0.01 to ±0.12 mm. Maximum payload capacity is 8 kg, with available reaches of 480, 550 and 650 mm.

Denso’s compact, space-saving design facilitates integration, while a high maximum moment of inertia allows a wide variety of end effectors and applications.

Electrical wiring and air piping are internally embedded in the robot arm, preventing interference with peripherals. The machine is also ANSI and CE compliant, which enables global deployment.

Applications include high-speed, high-precision pick and place in assembly processes, as well as packaging processes in the food, medical device, pharmaceutical and cosmetics sectors.
