博士西門子家用電器(BSH)導入三套COMET 5作為快速檢測應用
BSH Bosch und Siemens Hausgeräte GmbH
(Traunreut, Germany) use robot-assisted
optical 3D measuring system COMET 5 4M
for automatic component inspection
BSH Bosch und Siemens Hausgeräte GmbH
is a manufacturer of household appliances
renowned worldwide for their quality,
design and performance. The Traunreut
production plant manufactures mainly electric
cookers and ovens as well as hubs, combination
microwave ovens and electric kettles.
Innovations are a tradition in Traunreut:
The first cooker with carriage oven door
and the first oven with automatic pot
roasting were developed here. Other significant
innovations include a cooker with built-in
microwave oven, the first fully electronic
cooker as well as hubs with cooking and
roasting sensors.
The excellent product quality is guaranteed
through the use of cutting edge measurement
technology. With an automatic optical
3D digitizing and inspection system, BSH
Traunreut recently added yet another technological
innovation to their quality assurance
department. A total of three fully robot-assisted
optical inspection cells featuring the
latest COMET 5 sensor generation from
Steinbichler Optotechnik are being successively
implemented. Each inspection cell is equipped
with a 4-megapixel sensor that is positioned
by a robot with extension arm. This configuration
ensures a particularly high measuring
efficiency.
The object to be measured (mounting frame,
fascia panel, adhesive profile, etc.)
is placed on a special rotary table, in
which reference points from photogrammatic
measurements are integrated. The measurement
is started by entering the ID number of
the component to be measured. After data
acquisition with the COMETplus Reference
measuring software, the COMETinspect inspection
software automatically evaluates and documents
the results.
The decision of the project managers at
BSH to change from the previous tactile
sensing method to the optical measurement
method was based on good reasons: The
COMET 5 sensor configuration not only
achieves high-speed measurements, but
allows taking a full 3D image of the object
under test. Another decisive advantage
is that the non-contact measurement allows
testing bonded parts even before the bond
has completely set. Besides comparing
single points and single dimensions, the
system supports surface comparisons between
the measured object and a reference component
(CAD model).
If a 3D measurement data set exists, the
dimensions can also be checked at a later
stage, if required. Particularly the possibility
to measure bonded components (e.g. adhesive
profiles on glass panes) while the bond
is still setting drastically cuts the
time until the measurement result (QA
test report) is available. As a consequence,
any required corrective action can be
made early on in the running production
process.
The three robot-assisted COMET 5 inspection
cells will be presented during the 7th
Steinbichler InfoForum “3D Digitizing”
held at BSH in Traunreut on November 13,
2008.
