The HeiDetect FlexCT is a fully automated X-ray test system for workpieces. The system mainly consists of a 7-axis system, a 6-axis robot and the test technology including a powerful SIEMENS tube as well as the ISAR and PIDA evaluation software. The glass scales and robust granite substructure of the axis system ensure the high precision and accuracy as well as excellent temperature stability of the test system. As a result, the workpieces can be measured not just with absolute accuracy but also with repeatability. The 6-axis robot ensures a high degree of flexibility regarding the test pieces. Furthermore, the use of the robot allows the inline operation of the system. Depending on the test task, the robot can carry out the loading of the axis system or the positioning of the test specimens in the beam path.
The ISAR image acquisition and evaluation software for 2D tests and PIDA software for 3D tests as well as the XEye detector allow the reference-free parametrized evaluation of images. The ISAR and PIDA evaluation software and XEye detector are tested and proven developments of the Fraunhofer X-Ray Development Centre (Entwicklungszentrum für Röntgentechnik, EZRT) who is the development partner of Erhardt + Abt. The powerful SIEMENS tube, in particular, allows new and very fast operating modes, such as DRAGONFLY as well as imaging and evaluating during the movement.
The system's fully enclosed design enables its integration in the manufacturing process even under the extreme conditions of a mass production environment. The robot's gripper fingers and the workpiece retainer of the axis system must be adapted to the respective product and are therefore the only parts that need to be replaced during a product change-over. Naturally, additional functions such as laser machining and labelling can be integrated easily.
Since the detector by Fraunhofer EZRT features exceptionally low degradation, it only needs to be replaced at the earliest after approximately ten years in operation.
