Six axles for reaching into the box
Reliable gripping without having to determine the exact position and orientation of the gripped object beforehand - the Schunk AGE-U universal compensation unit should now also make this possible with robots.
Its complex design combines angular, lateral and rotational compensation and detects as soon as a deflection occurs, as Schunk explained. For example, ferromagnetic blanks can be picked up by a magnetic gripper when reaching into the box without having to know their exact position and orientation. Instead, a rough and therefore cost-effective localization is sufficient, for example using a simple 2D scanner, which reduces both the hardware and software costs as well as the programming effort. The module can also compensate for tolerances and positional deviations in six axes during automated assembly.
Component contact is detected
While compensation units previously available on the market only compensate angularly, laterally or rotationally, the AGE-U has combined rotational and angular compensation so that the end effector can freely adapt to the undefined position of components or perform joining operations with gripped components. The maximum possible compensation in the X and Y directions is plus/minus 2.7 millimetres, and plus/minus 6.1 millimetres in the Z direction. Lateral compensation around the X-axis and Y-axis is up to plus/minus three degrees, rotational compensation around the Z-axis is up to plus/minus eight degrees.
By returning to the home position both via springs and actively via compressed air, the flexibility of the unit can be individually adjusted by regulating the air pressure. At a pressure of six bar, the unit is completely rigid so that uncontrolled movements are ruled out when the handling system is moved.
The inductive sensing of the locking piston allows both the locked state and a deflection of the unit from the home position to be sensed. This makes it possible to precisely detect when the component is touched when approaching an object without knowing its exact position. The EMH magnetic gripper from Schunk mounted on the compensation unit can then be activated, for example, to pick up the part.
ISO flange for industrial and lightweight robots
The compensation module is recommended for handling weights of up to five kilograms and can be quickly and easily connected to various industrial and lightweight robots using the standardized ISO 50 flange without an adapter plate. The anodized aluminium housing and hardened steel functional parts ensure a long service life and reliable operation with minimal maintenance. The AGE-U is designed for one million balancing cycles. as
