Denso announces HSR high-speed four-axis robot

Oct. 6, 2017 – Denso Robotics says its new HSR high-speed four-axis SCARA robot features advanced vibration control, a newly designed, highly rigid lightweight arm, and improved heat dissipation in the base unit for performance and repeatability.

Denso says the 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. Standard cycle time (with a 2-kg weight) of the HSR robot is from 0.28 to 0.31 second 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. Electrical wiring and air piping are internally embedded in the robot arm, preventing interference with peripherals, notes the company. Suitable applications for the robot 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.
