RoboDEX - 7th Robot Development & Application Expo

NTN Corporation (hereafter, NTN) will exhibit at the “RoboDEX - 7th Robot Development & Application Expo” held from January 25 to 27 in Tokyo Big Sight, Tokyo, Japan.

This is an exhibition where robot manufacturers and robot-related companies around the world introduce the latest robots and related technologies which realize DX (Digital Transformation) at manufacturing sites. While many companies have been accelerating the utilization of robots at manufacturing sites to improve productivity and realize labor saving, NTN will introduce products such as Wrist Joint Module “i-WRIST™” and other products that contribute to function enhancement of robots and automation/labor saving at manufacturing sites.

“i-WRIST™” is a compact positioning module that achieves a wide range of angle movement while saving space. It can move smoothly like human wrist at high-speed to perform minor position (angle) changes, which vertically articulated robots are not good at doing, and can replace the various processes that were carried out by human with high-speed and high-accuracy.

At the booth, we will exhibit demonstration units of appearance inspection, grease dispensing as examples of system configuration using “i-WRIST™.” For appearance inspection application, we will also propose image processing system and equipment configuration in collaboration with System Integrator (SIer). In addition, we will introduce “i-WRIST™ Starter-Package” for the first time. It is an assembly product that consists of main unit of “i-WRIST™,” and peripheral parts/equipment so that customers can start the use of “i-WRIST™” easily.

In addition, NTN will exhibit “Multi Track Magnetic Ring” and “Multi Track Magnetic Encoder Integrated Rolling Bearing” as products that contribute to angle detection of vertically articulated robot joints. “Multi Track Magnetic Ring” can detect rotational speed and absolute angle with industry's highest level in angle detection resolution (maximum 20bit, resolution of approximately 0.00034°) by combining with a dedicated sensor, and can be used under usage conditions with oil and dust. “Multi Track Magnetic Encoder Integrated Rolling Bearing” is a product that integrates a bearing with “Multi Track Magnetic Ring” and a dedicated sensor. It contributes to reduction of the number of components, and downsizing/lightweighting of robot joints.

We look forward to seeing you at the event.

Main exhibits

Wrist Joint Module “i-WRIST™”

It is a compact positioning module that achieves a wide range of angle movement while saving space. This can move smoothly like human wrist at high-speed to perform minor position (angle) changes, which vertically articulated robots are not good at doing.

The maximum weight capacity is 3kg. It adapts to various mounting postures including upward, sideways, and inclined directions. By attaching end effectors such as camera, lightning, dispenser, and cleaning nozzle, it can contribute to automation, improvement in efficiency, and saving labor of various processes such as appearance inspection, grease dispensing, and cleaning.

Wrist Joint Module “i-WRIST™”

“Multi Track Magnetic Ring”

This is a ring-shaped product used to detect angle of robot joints. When combined with a dedicated magnetic sensor, it can detect absolute angle with high resolution.

As it is a magnetic product, it has superior resistance against vibrations, high temperatures, dust, oil mist. Since it is thin, lightweight, and has a hollow shape with a large diameter so that cables can be passed, it contributes to downsizing and improvement of design flexibly of robots.

In addition to the 64/63 pole pairs series, the compact and lightweight type, the 32/31 pole pairs series is also available.


							“Multi Track Magnetic Ring”

“Multi Track Magnetic Encoder Integrated Rolling Bearing”

This is a unit product integrating bearing with magnetic type encoder. By reading changes in magnetic poles of “Multi Track Magnetic Ring” attached to inner ring of bearing with magnetic sensor IC equipped with outer ring, it can detect rotational speed, direction, and absolute angle.

The product eliminates the need for transmission devices like couplings that connect joint shaft and rotary encoder, achieving downsizing/lightweighting of robot joint. The operation for mounting/setting up couplings is also eliminated, making assembly of robot easier. Dimensions and load capacity of the bearing in the product are the same as those of conventional bearings, and can be applied to a wide range of robots.
