RSF – RobotScanFlex

The RobotScanFlex (RSF) was developed for automated filter integrity tests on cleanroom ceilings and walls in order to guarantee a more efficient, reproducible, and higher quality measurement process compared to manual procedures. A particle counter and a measuring probe are used to automatically detect particles downstream of the filter unit and the results are displayed in real-time on the tablet screen using the ScanWare control software via 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 measurement report can then be created in post-processing using the integrated ScanWorx analysis and evaluation software package.

The robotic arm (SCARA) has a maximum reach of 1850mm and is controlled by the ControlBox (CBOX) while mounted on a height-adjustable tripod. The stand can be used to adjust the probe height between 1800mm and 4000mm above the floor level. Different sizes of the stand are also available on request. The particle counter is attached directly to the stand in order to minimize the required tube length to the probe to avoid any measurement inaccuracies. The CBOX, to which the stand is fixed, is mounted on castors so that the entire system can be moved freely around the room. The RSF is placed firmly on the floor under the filter element to be scanned.

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.
