The HeiDetect Wheel Robot wheel test facility achieves an extremely high throughput thanks to its industrial robot and is therefore ideal for inline operation in the mass production of cast aluminium wheels. Several areas of the wheel can be tested in one testing position by using a larger detector. This benefit means that the number of handling steps can be reduced, thus shortening the test time for each wheel.
HeiDetect Wheel Robot is a fully automatic wheel test facility and, through the integration of the ISAR image evaluation software and the XEye detector developed by the Fraunhofer Institute for Integrated Circuits, allows almost pseudo error-free evaluation with stable image quality. The efficient processing of images allows casting errors such as shrink holes, pores, cavities and foreign matter in the range of 3% of the radiographed wall thickness to be detected and classified. Large areas of oxide can be detected from a size of 1 % of the wall thickness.
Further benefits are offered by the automatic wheel detection and by incorporating barcodes. This enables the alignment of the wheels to be specified and monitor the test results. The HeiDetect Wheel Robot wheel test facility from HEITEC PTS GmbH meets the latest requirements for the group of wheels and handles wheel sizes from 13” to 24”.
The ISAR evaluation software offers an ergonomic Windows-based graphic user interface via which the test parameters can be set specifically for customers. Key data can be transmitted via an existing operating data acquisition system.
Specially prepared test results are transmitted to production in real-time, thereby enabling trend analysis and continuous product quality optimization, aiming to minimize scrapping.
The small installation space and full enclosure mean that incorporation into the production process is possible, even in extreme conditions in mass production. The wheel gripper is designed so that wheels with a faulty rim flange can also be tested. Further functions such as lasing and labelling can also be incorporated without any problems. As the detector from the Fraunhofer Institute for Integrated Circuits shows an extremely low rate of degradation, a replacement will not be required for at least 10 years or so.
