Vitronic presents the third generation of sensors in the VIROwsi
camera-based weld seam inspection system. Weld seams on aluminum
components can now also be inspected safely thanks to greater dynamics
and depth of focus and improved evaluation software.
Extreme reflectivity and darker residue traces which reflect less light
back to the camera: automated weld seam inspection for aluminum
presents a much greater challenge to automated inspection systems than
for steel. The third generation of sensors in the VIROwsi weld seam
inspection system from VITRONIC offers significantly higher dynamics,
allowing weld seams in aluminum with very dark areas to be inspected
just as safely as in steel.
Optimum data quality thanks to combined 2D/3D acquisition: The
combination of 2D and 3D acquisition of the weld seams in the VITRONIC
VIROwsi is also new. Therefore, it is even possible to detect whether
or not welding has taken place at all, such as in laser welding. This
enables further evaluation options in the 2D range if geometric
information is missing.
The depth of focus has also been optimized thanks to improved camera
technology. The benefit: the entire depth view area of the sensor can
be used for inspecting, depending on the part and the accessibility. A
predefined distance no longer has to be strictly maintained.
Optimized software has also allowed the resolution to be increased
significantly: inspection can now be done at full resolution and the
highest inspection quality even at high cycle times.
More flexible assembly, easier commissioning: The third generation of
the VITRONIC VIROwsi weld seam inspection system has a standardized
interface and a gigabit ethernet cable suitable for use with robots.
The sensor can be mounted alternatively from both sides. This offers
benefits in the copy of system cells, which in turn prevents once again
simulation and makes both construction and commissioning easier. The
optimized design with a slimmer construction also allows easier access
to the part and the weld seam.
Profile - VITRONIC VIROwsi weld seam inspection system: VIROwsi
determines the size and position of all relevant defects in weld seams,
such as pores, holes and undercuts, in real time. All geometric
features of the seam, such as the length, width, height etc., can also
be recorded. All results are fed into a log and are saved for tracking.
The seam quality is thus documented completely. The data recorded forms
the basis for manual and automatic re-working of the seam and for
targeted process optimization.VITRONIC at Automatica 2012, May 22-25, 2012: Hall 2, Booth 203
