Powerful like acamera system,simple like a sensor
In automation technology visions sensors
are today an integral part of assembly,
production and quality control and last
not least increase efficiency.
They are cameras with application-specific
evaluation, i.e. reliable electronic eyes
at low cost with a high degree of integra-
tion.
From the camera to the sensor.
A few years ago high-price camera sys-
tems were needed. Due to technical
developments and continuously falling
prices for components ever more intelli-
gent functions could be implemented
at low cost in an ever smaller space.
Compact vision sensors not only replace
camera systems but also offer additional
application options. For the variable
position detection of objects or scenes
they replace, for example, complex prox-
imity sensors or multiple sensor solutions
such as sensor bridges, when pallets or
crates are monitored for completeness.
Easy to integrate
One of the distinguishing features of
vision sensors is their simplicity. Whereas
image processing systems can usually only
be integrated into the production process
by qualified personnel or cost-intensive
external integrators, vision sensors can be
used without previous knowledge due to
their application-specific nature.
Easy “parameter setting” instead of com-
plex “programming” is the motto. Ready-
to-use function blocks support the
integration into the PLC. An Ethernet
process interface is used for data transmis-
sion, parameter setting and remote main-
tenance. Also, all units have switching
outputs to signal successful testing.
So vision sensors offer the same ease of
use as binary sensors.
Robust and compact
Another advantage: Due to their high
protection ratings and wide temperature
ranges ifm vision sensors can in the truest
sense of the word be brought very close
to what is actually going on. They are also
distinguished by a particularly high de-
gree of integration. In contrast to com-
plex camera solutions, all necessary
components such as illumination, optics,
evaluation and output logic are integrat-
ed into the industrially compatible
housing. Tasks such as quality control,
monitoring completeness or reading 1D
and 2D codes can easily be performed at
low cost using ifm vision sensors.

For industrialapplications
As for a toy box: The O2D vision sensorcan recognise and assign previouslydefined objects and their contours orstructures in order to check complete-ness, position and orientation.
Contour sensor
Comparable to a counting frame or sliderule, the O2V vision sensor counts allpixels of the areas of identical grey-scale values of an image.Furthermore, it can group accumulationsof certain grey-scale values to individualobjects and assess by different criteria.
Pixel counter
Today bar codes are widely used andcan be understood as font styles to beread from right to left.2D codes encode the information inthe area. Similar to a domino puzzle,unambiguous information is conveyedwhich is read by the O2I vision sensor.
Code reader
Similar to a bed of nails, theO3D 3D sensor scans the current scenein depth.These more than 23,000 measureddistance values can be used to createa multitude of virtual sensors, forexample to check that a crate is com-plete with any kind of bottles.

Presence monitoring in automatedassembly: In this application, threebody clips are positioned on a panel.By monitoring the contours of severalclips, the missing parts are identified.Applications that otherwise could onlybe solved using several photoelectricsensors can now easily and reliably beadjusted and controlled by means ofonly one system.

Monitoring presence or completenessfor assembly steps carried out manu-ally or by machine.The choice is yours: field of view sizesof 14 x 20 mm to 960 x 1280 mm for alarge range of applications from fineto rough processes.Objects can also be detected irrespec-tive of the position like the clip in thisexample.
With an intuitivestep-by-step inter-face and good /bad parts the usercan simply createa model of theobject to be recog-nised. The recog-nition softwarecompares theobject with thesaved ideal,
regardless oforientation, andtransmits theresults (good orbad, position,orientation) to thehigher-level PLC.The sensor canmanage up to32 separate taskswith a maximumof 24 models each.

Whereas commonvision sensorscheck parts on thebasis of definedcontours (like thecontour sensorO2D) the newO2V pixel countercompares on thebasis of variablefeatures.
Object inspection O2VChecking variable
features ofobjects and scenes
The pixel counter checks the presenceor position of weld seams, weld spotsor areas that went blue in variablydegrees due to the high weldingtemperature. Even irregularly appliedmaterials such as glues or greases aredetected.

The vision sensor checks the presenceof adhesive labels or imprints, such asproduction or best before date.The sensor also reliably detects colourmarks such as mounting points ordefect marks – applied by machine orby hand.
Instead of a de-fined contour theuser determinesrelative featuresused by the sensorto assess an objector a scene. Withinfreely selectabletolerances thesensor determinesfeatures such asarea, size, round-ness or compact-ness of an object.
Furthermore, thegrey-scale valuescan also be usedfor assessment.
The O2V visionsensor is reliablyused for the full /empty control oftransport andproduction vessels.
The photo on theleft, for example,shows a 100 %empty control of achocolate mould.

Award winning:The first industrial 3D sensor thatdetects objects in three dimen-sions at a glance. The sensoroperates on the principle of timeof flight measurement based onPMD technology.
Precise:The resolution of 176 x 132 pixelsresults in 23,232 distance valuesper measurement for the detailedassessment of the application.
Independent:Illumination, time of flightmeasurement and evaluation areintegrated into an industriallycompatible housing.
Easy:Switching outputs and analogueoutputs for the simple integrationinto the control environment.
Far sight:Range up to 5 m irrespective ofthe object colour, robust againstextraneous light.
Levelmeasurement:
The sensor is suit-able for contin-uous level measu-rements of non-transparent solidsand bulk materialsin tanks, silos,hoppers or inheaps. Monitoringconveyors for levelor belt usage isalso possible. Inthe measuringrange the sensordetermines thelevel via the de-fined backgroundand transmits theanalogue levelvalue or has thefunction of a pointlevel switch.

Monitoringcompleteness:
Consumer goodsand industrialproducts are oftendelivered inhomogeneouspackaging.If a pallet withonly one incom-plete handlingunit reaches thecustomer, theyoften return thewhole pallet.
This causes a lot ofadditional cost, inparticular in caseof perishablegoods. On thebasis of colour thesensor checks thehandling units forunderfill and over-fill. As opposed toconventional solu-tions, there isflexibility inchanging the typeor size of thehandling unit.
Objectdimensioning:
Size determinationfor volume calcu-lations or sortingapplications.Warehouse, postroom, logistics dis-tribution centre ortransport system:optimisation ofthe storage area isneeded every-where.
The sensor has thefunction of a sim-ple thresholdswitch or transmitsobject size, orien-tation and positionto the warehousemanagement orERP system.In addition, qualityparameters helpdetect damaged ordeformed object.

3D object recognition for conveyingand packaging technologies
Package dimensioningToday countless courier services chargenot only according to the actualweight of an object to be sent but alsoaccording to the object's bulkiness, i.e.according to strap length or dimension-al weight. If the dimensional weight orthe strap length exceeds the actualweight, the shipping or freight costsare calculated on this basis.
Full crate inspectionThe sensor checks handling units forcompleteness, e.g. workpiece carriers,bottle crates, outer packaging, blisterpacks or pallets.Automatic position and orientationadjustment guarantees a stablefunction even with a variable objectposition.
