Flexible, non-destructive X-ray testing

HeiDetect FlexCT is a fully automatic X-ray test machine for workpieces. The system essentially consists of a 7-axis system, 6-axis robot and test technology featuring a high-performance SIEMENS tube and evaluating software components such ISAR and PIDA. The glass scales and stable granite base of the axis system enable the test system to achieve high accuracy and maintain very good temperature stability. This allows both absolutely accurate and repeatable measurement of the workpieces. The 6-axis robot provides for high degree of flexibility with regard to the test pieces. As for the robot, the system can be operated inline as well. Depending on the test task, the robot can load the axis system or positioning the specimen in the beam path.

The image acquisition and evaluation software ISAR for 2D tests and PIDA for 3D tests as well as the detector XEye enable reference-free, parametrizable evaluation of the images. The evaluation software ISAR and PIDA as well as the detector XEye are proven and tested developments of the Fraunhofer Development Centre for X-ray Technology (EZRT), the development partner of HEITEC PTS GmbH. In particular, the powerful SIEMENS tube enables new and very fast modes of operation such as DRAGONFLY to take images and recording and evaluate them during movement.

The following operating modes are available with HeiDetect FlexCT

  • PIDA Axial CT: The turntable rotates the workpiece on a fixed position at a programmed speed (rpm).
  • PIDA Axial CT Robot: The robot holds the workpiece in the beam path and rotates it continuously.
  • PIDA Helix CT: The turntable rotates the workpiece continuously while the source and detector move in parallel to the rotary axis.
  • PIDA Helix CT Robot: The robot holds the workpiece in the beam path and rotates it continuously while the source and detector move in parallel to the rotary axis.
  • ISAR Stop and Go: The robot approaches to any number of predefined positions. Whenever any of the positions is reaching, an imagine is taken.
  • ISAR DRAGONFLY: The robot moves to any number of positions and slows down the velocity while approaching to the positions. The image is taken while moving to save valuable cycle time.

Safe and efficient system technology

The full enclosure enables integration into the manufacturing process, even under extreme conditions in mass production. The gripper fingers of the robot and, if necessary, the component fixture of the axis system are to be adapted to the respective product and thus, are the only parts to be replaced during product changeover. Moreover, further functions such as lasering and labelling can be incorporated without any problems.

Since the detector of the Fraunhofer EZRT is characterized by an extremely low degradation, replacement is necessary after about ten years at the earliest.
