Fully automated wheel test facility "HeiDetect Wheel Robot"
|
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 for an almost
pseudo error-free evaluation with stable image quality. Due to the
efficient processing of images, casting errors such as
shrink holes, pores, cavities and foreign matter can be
detected and classified in the
range of 3% of the radiographed wall thickness. Large areas of oxide can be
detected from a size of 1% of the wall thickness.
Further benefits are the automatic wheel
detection and the incorporation of 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.
Reliable and efficient
systems engineering
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.
