Suitable cartesian robot systems
Cartesian robots can be adapted very well to the respective application conditions due to their modularity. They require less space than articulated robots, for example, because they only have the functions that are actually needed.
IAI offers cartesian robots as 2-6 axis combinations with servo motors as standard or high-precision types. An equally extensive portfolio is also available of lower-cost cartesian RoboCylinders with stepper motors.
Cartesian robots with NSA linear actuators in combination with ball screw drives offer excellent machining capabilities. They are offered as standard as 6-axis robots with base mounted or slider mounted Z-axes.
NSA nut rotating axes are linear actuators with a servo motor integrated in the slider. Instead of moving a slider through a rotating ball screw, the integrated servo motor drives it through a rotating nut. The fixed spindle enables high-speed movements with long travels, resulting in shortened cycle times.
For more complex applications, double and multiple slider versions are available, with all slides being independently controllable.
The latest Cartesian RoboCylinders are based on the RCP6 series, which has slimmed down the design compared to previous versions and allows higher speeds to be achieved. All axis combinations are equipped with high-resolution battery-free absolute encoders as standard. This eliminates the need for homing, home sensor, battery maintenance and more.
All vertically used axes can be optionally equipped with a brake to prevent the carriage from sinking in the event of an interruption in the power supply.
Robot wrist units for maximum flexibility
With the robotic wrist (WU Wrist Unit), Cartesian systems have the same flexibility and degrees of freedom as articulated robots. IAI's unique design makes the components light and compact. Can also be used for an orthogonal axis system with interpolation function.
The wrist units are equipped with two joints: the tilting joint for inclination covers a working circle of ±100⁰, while the rotating joint for rotation can be rotated by ±360⁰. The two stepper motors used move these axes at speeds between 750 ⁰/s and 1,200 ⁰/s.
