iRSF – integratedRobotScanFlex

The robotic arm (SCARA) of the integratedRobotScanFlex (iRSF) has been developed to ensure a more efficient, reproducible, and higher quality measurement process. In isolators and RABS, the robot cannot be placed on the floor and therefore has to be attached to the walls or doors of the isolated area. The system differs from RobotScanFlex (RSF) only with regard to the mounting and the length of the robot arm segments. The robot arm of the iRSF can be mounted directly to the doors of an isolator or RABS and can then be removed residue-free after the measurement. During the entire measurement process, the doors remain closed and sealed (isolator). Thus, the airflow and pressure in the isolator are not affected and a measurement can be carried out under production conditions.

In an automatic filter integrity measurement with iRSF, the particles downstream of the filter unit are automatically detected using a particle counter and a measuring probe and the results are displayed in real-time on the tablet screen using the ScanWare control software with a 2D-heatmap. During the entire measurement process, a constant distance between the filter surface and the probe is maintained and a constant scan velocity is guaranteed. A report can then be created with the post-processing feature using the integrated ScanWorx analysis and evaluation software package.

The robotic arm (SCARA) has a maximum reach of 1400mm and is controlled by the ControlBox (CBOX) while mounted on a bracket that can be attached to an isolator or RABS door. The particle counter is attached directly to the mounting plate in order to minimize the required tube length to the probe to avoid any measurement inaccuracies.

A round probe is attached to the end of the SCARA robot arm, which is moved in a meandering pattern across the filter surface with an overlap of at least 10% of the probe diameter according to the standards.

The length of the probe extension is variable and can be selected to fit the spatial requirements for each filter element respectively. Thus avoiding potential obstacle collisions below a filter unit while maintaining the required distance of 3-5cm between the probe and filter surface.
