New wrist

IAI Industrieroboter presents a robot wrist for Cartesian robot systems for the handling sector. With this product, the specialist for pneumatic electric automation aims to provide the same flexibility and all degrees of freedom that were previously only possible with articulated robots.

The new unit has two joints: the tilting joint for inclination covers a working circle of plus/minus 100 degrees, and the swivel joint for rotation can be rotated by plus/minus 360 degrees. (Image: IAI)

The advantage of Cartesian robots in many applications is the smaller working area compared to articulated robots. The unit has two joints: the tilting joint for tilting covers a working circle of plus/minus 100 degrees, and the swivel joint for rotation can be rotated by plus/minus 360 degrees. The two stepper motors used accelerate the axes at speeds of 750 to 1,200 degrees per second. The series will initially start with two variants that can each move one and two kilograms of payload and are therefore aimed at small parts production.

For next year, IAI is promising two further variants with payloads of five and ten kilograms. The wrist unit is programmed and controlled by the IAI MSEL controller, which can store up to 255 programs and 30,000 positions. It is controlled via discrete inputs and outputs or via a standard fieldbus system. At 195 x 130 millimetres and an installation depth of 125 millimetres, the unit is compact. The 1.4 kilogram controller can be mounted on a top-hat rail and installed in the control cabinet. pb
