Application

Applications for verification span across almost all sectors. To

maximize read rates in production and logistics and to make

them predictable, it is essential to measure the marking quality.

The following sectors and applications are a particular focus for

MV440 verification systems:

Automobile industry

• Needle marking (DPM): e.g. cylinder heads, cylinder blocks,

etc.

• Laser marking (DPM): Cylinder pistons, gearbox components,

etc.

• Laser markings on electronic components, printed circuit

boards, or enclosures

Pharmaceutical industry

• Print or laser markings on medicines (DPM, OCR)

• Aerospace industry

• Needle or laser markings on gas turbine blades (DPM)

• Needle or laser markings on jet engine components (DPM)

Medical equipment

• Laser markings on implants (DPM)

• Laser markings on medical devices (DPM).

Electronics

• Needle or laser markings on hard disk components

• Lasered or etched markings on hard disk components (DPM)

Semiconductors

• Laser markings on rigid and flexible circuit boards (DPM)

• Laser markings on enclosed semiconductor components,

heat sinks or heat exchangers (DPM)

"Veri-Genius" can be used anywhere where environmental con-

ditions permit the use of MV440 code readers - for details, see

SIMATIC MV440. Standard ring lights and lenses are designed

to achieve IP67 degree of protection by means of the protective

barrel, and for glass-free use in the food and beverages industry.

If light sources or lenses are used outside the protective barrel,

they must be used in compliance with their specification.

Any host and HMI systems required must be selected sector-

specifically and project-specifically. The range of application of

the selected test method is defined in the specification of the test

method and compliance is essential if universally valid results

are to be obtained.

Design

All SIMATIC MV440 stationary code readers are basic units un-

der the terms of the license. The verification functionality is en-

abled by transferring the license key from the USB flash drive on

which it is supplied to the MV440 code reader by means of

SIMATIC License Manager.

Verification with MV440 verification systems is suitable for both

inline and offline measurements. In both cases, the specification

of the verification standard used must be observed to ensure a

robust measurement result. This means, for example, that the

lighting and alignment of the light source, camera and test ob-

ject must be in accordance with the definitions of the respective

standard.

If only one light source is used, the MV440 can control an exter-

nal light source using the existing image-synchronized digital

output, or the external light source can be operated continu-

ously.

If more lighting directions are required, an external controller can

be used to activated the desired lighting and to start each indi-

vidual measurement by means of triggering. The result from the

quality measurement or the relevant partial measurement is out-

put directly by the MV440 after completion of the measurement.

In the case of more than one measurement, it is the task of the

external controller to combine the partial results into an overall

result and to visualization this.

If the test method requires calibration, the calibration card in-

cluded in the scope of supply can be used in most cases. In

cases with extreme imaging requirements (e.g. with very small

or very large codes), the task of calibration must be resolved ap-

plication-specifically.
