PRODUCTS FOR LASER BEAM ANALYSISIN AUTOMOTIVE INDUSTRY

Laser Beam Diagnostics
for Industry 4.0
Tomorrows production will face high demands: It will have to be intelligent,flexible, efficient, and sustainable. But isn’t it already like that today?
Ever briefer product life cycles are satisfying ever more rapidly changing
demands and correspondingly bring with them high demands for processsystem flexibility. Top-notch quality is a key factor here and detecting deviations is an integral part.
Stopping machines embedded in a 24/7 network of interrelated steps
is often an economic disaster. Maintaining consistent quality of the laser
beam is a basic prerequisite to ensure reliable cycle times in production.
The laser is a tool vulnerable to wear, however, and even the smallest
irregularity could result in lower workpiece quality or unnecessary excess
waste. With regular focus analysis, you can track even gradual changes
in the laser beam, interfere in a targeted manner, and perform predictive
maintenance: Is it caused by the beam waist location, beam symmetry,an alignment error, or thermal effects?
Harsh production environments, limited construction space and constantmechanical stress: This too can be a face of state-of-the-art Industry 4.0.
PRIMES offers solutions suited to these and many other challenges in laser
beam diagnostics. For heavily polluted production environments, we use
particularly robust components to protect the valuable lenses and mirrorsof the measuring devices. When space is limited, we use especially compact measuring devices or adapt special optical elements to widen theincoming laser spot. Almost everyone along the value chain of high power
lasers, including laser manufacturers and the automotive industry, trusts inthe quality of PRIMES devices for laser beam diagnostics – as part of theirstrategy for efficiency and flexibility.

Fast, reliable and highly accurate –PowerMeasuringModule PMM
The industrial standard for power measurements of high power lasers, fully integrated
in your automated process.

The PRIMES PowerMeasuringModule PMM is
the industry standard for measuring high power
lasers in industrial processes. It offers fast andreliable quality assurance in rough and synchronized production environments. With standardized interfaces, it‘s easy to integrate anddelivers highly accurate measurement results
to the machine interface. Using the calorimetricprinciple, it provides extremely fast measurements within 3 seconds, allowing for qualification during production line part exchanges.
Fast laser power measurement enables precise
process control, quickly identifying irregularprocesses due to defective components.
This reduces scrap production and allows
for better planning of service calls, saving
time and costs in a price-sensitive production
environment. New: The PMM‘s field ofapplication was extended to low average
powers as well as pulsed beam sources.
The use in the blue and green spectral range
is particularly suitable for laser processingof copper materials and in battery production
for e-mobility.
Additionally, the PMM AP3sM, features anintegrated Micro Lens Array for measurements up to 200 kW/cm² close to the focus,
optimizing space usage even further.

with all common interfaces. The PRIMES PMM is your reliable partner for process control inindustrial laser applications, proven by more than 5.000 units installed worlwide.

Autonomous and durable –FocusParameterMonitor FPM
2-in-1 online beam characterisation, measuring power and caustic, designed for­seamless integration into production environments.

The FPM is a compact, autonomous sensor
that measures laser power, power density
distribution and caustic online. It is designed
for the integration in a production line andcan perform measurements during partchanges or other down times within a fractionof a second. The FPM is the ideal tool tomonitor the overall performance of your laser
station.
The FPM can perform caustic measurements
conform to ISO 11146. It is easy to integrate
and requires no cooling. Measurements require short laser pulses only, which resembles

the welding process of high precision tasks(remote welding of e.g. battery packs or
hairpin welding). This allows to detect irregular beam properties before they can lead toa defective part. With the FocusParameterMonitor, seamless documention of the laser
performance is possible – which is crucial
for costly value chains like the production ofbatteries and fuel cells.

Conclusion
The FocusParameterMonitor measures laser power, captures the power density distribution
and calculates the characteristics of the focussed laser spot autonomously. The data is
automatically transfered to the machine PLC and can thus be easily checked and stored.
By setting upper and lower boundaries, it is possible to detect a drifting process and towarn the operator. The measurement results can be documented for quality assurance.
The FMP has a compact and robust design, features field proven PRIMES technology andis nearly maintenance free.
