Industrial robots are used at factories and other sites around the world. Their use is expected to increase even more, due to work place automation, progress in streamlining and decreasing labor forces. The basic functions of industrial robots include positioning, grasping objects, assembling and providing surface treatments such as painting. Along with the evolution of related technologies, such as sensing and IoT, advanced functions are also evolving. High performance to meet the needs of trending technologies is required for the bearings, linear motion rolling guides, and mechatronic parts used in industrial robots.
Industrial Robots
Welding Robot
Welding robots have joints and arms like a human. They can be manipulated to combine motions such as extension, bending, stretching, left/right movement, and turning to perform welding work from any position. Since welding work is carried out in harsh environments where high heat, dust and fumes are generated, the rotating bearings and linear motion rolling guides must be able to perform effectively under these conditions.
Remote Operation Work Robot
A remote operation work robot is operated from a remote location using electrical signals or other transmission, typically in environments where it is difficult for a human to do the work. The bearings used must have high rigidity and be compact, as well as provide dustproof and rustproof performance for outdoor work.
Power Assist Suit
The power assist suit is a device that reduces the burden on the human body when raising and lowering heavy objects. It is most often used in manufacturing, agriculture, logistics, nursing care, or other jobs that require heavy lifting. In order to enhance and assist human function using the power of the drive units, the bearings must have high rigidity and be capable of balancing loads from any direction. They must also be compact to reduce the load on the user without impairing operation.
Automatic Setting for Mobile Devices
A mobile automatic setting device can automate specific initial settings on mobile devices, such as smart phones and tablets, that previously had to be done manually. It is mainly used at corporations where a large number of settings must be made on various devices. Since accurate touch pen operation is required on multiple devices, and the surrounding environment must remain uncontaminated, high rigidity, high accuracy and cleanliness are required for the linear motion rolling guide and mechatronics products.
Human-Collaborative Robot
Human-collaborative robots play an important role at production sites in many factories. They can detect the position and movement of workers, enabling the worker and robot to work in the same space safely. Since human-collaborative robots perform multi-jointed and complex movements, moment is applied to the arm, with the robot itself subject to a complex load. Bearings that can withstand large, complex loads are necessary for human-collaborative robots.
Reduction Gear
A reduction gear is a device that obtains torque proportional to the reduction ratio by outputting power from a power source, such as a motor, while reducing rotational speed. Bearings in reduction gears, must support the high precision and high performance required of these mechanical devices.
