Cartesian Robots in Hundreds of Standard Configurations
On account of their modularity, cartesian robot systems can be more easily adapted to the respective applications conditions than classic robot solutions. In addition, these energy-efficient systems frequently offer further benefits, such as a low space requirement and only precisely the function that is actually required in the respective application.
IAI supplies Cartesian robots as 2 to 6-axis combinations in hundreds of standard configurations, firstly with a 230 V servo motor as a standard and precision version. Secondly, there is an equally extensive range of inexpensive Cartesian RoboCylinders with a 24 V stepping motor and in some cases with a 230 V servo motor, for which there are 396 combination possibilities (in fact there are 7056 if one includes the cable chain selection). All models can be adapted to suit the individual customer if necessary.
Complete systems - standard or precision type
The most frequently requested configurations are the 2 or 3-axis complete systems in a standard or precision type. All systems are compact, highly-stable units with a low weight and high rigidity. Each one is delivered with the associated connecting parts and cabling and can be installed immediately in a production line. A wide range of configurations ensures that all the special requirements of every user can be met.
Cartesian system with nut rotation servo motor
Combined axes with a nut rotation servo motor offer outstanding transport. The servo motor built into the slider moves the slider along the fixed ball screw. This allows heavy loads to be transported at a very high speed, even with a long stroke.
Inexpensive cartesian RoboCylinder
The latest cartesian RoboCylinder is based on the new generation of linear systems from the RCP6 series. Just like them, these cartesian robots also feature high-resolution battery-less absolute encoders and thus have the same advantages: the elimination of reference drives and a home sensor, the elimination of battery maintenance, easy restarting after an emergency stop, etc.
In comparison with the predecessor series, the new generation of Cartesian robots has a 2.4-fold faster maximum speed in combination with a PCON controller. As a result, the cycle times could be significantly reduced and productivity noticeably increased.
The repeatability of all Cartesian robot systems is +/- 0.01 mm. All vertically used axes can also be equipped with a brake so that the slider is prevented from sinking down in the event of an interruption of the power supply.
New robotic wrist unit for cartesian robot systems
The new robotic wrist for cartesian robot systems now allows for a kind of flexibility and all degrees of freedom for Cartesian systems which have previously only been possible with articulated robots. A substantial benefit of the Cartesian robot in many applications is the very much smaller working area compared to articulated robots.
The innovative wrist unit has two joints: The tilting joint for swivelling has a working circle of ±100⁰ while the rotary joint can be rotated around ±360⁰. The two pulse motors accelerate these cylinders at speeds of between 750 ⁰/s and 1,200 ⁰/s.
