ON THE POINT - THE SMALLEST SPOT SIZES FOR THE LARGEST FIELDS
Many laser beam deflection units can weld and cut – but only a handful can do so “on the fly”. The AXIALSCAN FIBER-50 (AS F-50) ensures that the laser process is highly dynamic and precise, even when the workpiece is passing under the deflection unit at varying speed.
This puts the AXIALSCAN FIBER-50 in a class of its own for you as a machine manufacturer, commercial vehicle manufacturer, shipbuilder or rail vehicle manufacturer. The pre-focussing deflection unit can, among other things, separate the contours of electrical connection surfaces (tabs) on batteries with precision during the foil winding process. This benefit is possible thanks to the pulsed laser beam – highly dynamic with position accuracy – that is directed from the AXIALSCAN FIBER-50 deflection unit onto the workpiece.
Another ingenious feature of the AS F-50 is that it works with the smallest spot size on processing field sizes of between 300 x 300 mm and 850 x 850 mm. This makes the pre-focussing deflection unit the no. 1 choice for seamless laser processing – and for ensuring sharp edges without noticeable heat affected zones when separating electrode foils. Another area of application is the welding of bipolar plates for fuel cells with very thin, stainless steel plates with a thickness of less than 100 μm and a complex capillary structure. For this purpose, the AS F-50 uses a high level of position accuracy and creates fine weldseams with stable penetration depth to prevent damage to the bipolar plate.
The smallest spot sizes for the largest fields
The AXIALSCAN FIBER-50 can be equipped with various fibre sockets – including a QD socket (LLK-D) – making it compliant with the strict regulatory requirements in the automotive industry. In combination with protection rating 64, it stands for the very best in process reliability.
We strive, above all, to achieve usability, quality and productivity. That’s why all our products are developed, built and tested in our own laboratories and production facilities. We make our complex, pre-focussing deflection units and welding modules in our ISO Class 7 clean room to ensure an unrivalled level of optical cleanliness and strength. We guarantee fast service and expert maintenance by means of our global support network.
Thanks to its structural design and compact dimensions, the AXIALSCAN FIBER-50 deflection unit with integrated collimator is easily integrated into existing machine configurations.
The horizontally arranged QBH interface – which can alternatively be implemented as QD – prevents the entry of dust particles when the laser fibre is connected. A second protective window that can be replaced in a matter of seconds minimizes maintenance. This increases productivity and process reliability.
The AXIALSCAN FIBER-50 deflection unit makes chromatic aberrations a thing of the past! The elimination of the need for F-Theta lenses guarantees the best possible light quality, which in turn opens up a wide range of options for coaxial inline process control. The unaltered spectrum of the process light ensures precise capture of a huge amount of reliable data, which you can use to evaluate and reproduce the quality of your components at any time using suitable sensors and analysis software.
The structural design of the AXIALSCAN FIBER-50 also offers extensive monitoring of a wide range of manufacturing parameters. Which means that process monitoring can be customized to meet any in-dividual requirements. For you as machine and plant manufacturer with a focus on automotive manu-facturing, a commercial vehicle manufacturer or a rail vehicle manufacturer, this adds up to complete control over the quality of the bipolar plates for your fuel cells – to name just one classic component in your production line.
At any time and at any point. You benefit from valid information about component quality and about the manufacturing process itself. This makes the pre-focussing AXIALSCAN FIBER-50 the technology that enables quality assessment during the manufacturing process itself thanks to powerful sensors. As a result, both incorrect measurements due to excessively refracted light and costly software adjustments for camera monitoring are no longer a concern.
Guarantees fast and easy interactions for customised programming. User-friendly set-up and calibration of the deflection unit and effortless automation.
Can be used universally as well as specifically for individual requirements. The laser system can thus be op- timally controlled, optimised during development and monitored during operation.
