About
Resolves the shortcomings of previous SCARA and parallel-link robots. Offers both superior positioning accuracy and high speed. YAMAHA'S Next-Generation SCARA Robot: The YK-TW Omnidirectional Type.
Feature
User: We want a smaller equipment footprint.
Layout design freedom
The YK-TW can move anywhere through the full 1000 mm* downward range.
Featuring a ceiling-mount configuration with a wide arm rotation angle, the YK-TW can access any point within the full 1000 mm downward range. This eliminates all motion-related restrictions with regard to pallet and conveyor placement operations, while dramatically reducing the equipment footprint.
Improvement of productivity
The standard cycle time for moving 1-kg load horizontally 300 mm and up/down 25 mm is shortened by approximately 36 % compared to existing YAMAHA models.
User: We want a higher quality assembly system.
Higher quality
The YK-TW offers a repeated positioning accuracy of +/-0.01 mm* (XY axes).
This is a much higher repeated positioning accuracy than that offered by a parallel-link robot. This was accomplished by optimizing the robot's weight balance through an extensive re-design of its internal construction. The lightweight yet highly rigid arm has also been fitted with optimally tuned motors to enable high accuracy positioning.
User: We need to reduce our tact times.
Higher productivity
The YK-TW offers a standard cycle time of 0.29 secs.*※
The Y-axis (arm 2) passes beneath the X-axis (arm 1) and it has a horizontal articulated structure, allowing it to move along the optimal path between points.
