The Laser Processing Head RLSK
is a Pioneer of the Third Dimension
and Sets New Efficiency Standards
Among Solid-State Lasers
The HIGHYAG scanner based RLSK
combines the advantages of the remote
laser welding principle: a large working
distance and the capability to position the
beam in a 3D work space.
In its entire 3D work space, the RLSK allows
beam positioning within milliseconds and
it guarantees a uniform beam diameter.
This 3D capability permits the remote laser
processing head to accurately position
the beam along high speed robot motions
enabling short cycle times and a very
high utilization of the laser and the robot.
Therefore, the RLSK is perfectly prepared for
“Welding-on-the-fly”.
The RLSK can be controlled by offline
programming using the RLSK Studio or by
direct control using the robot via the CAN
bus interface.
The new version of the RLSK comes with
new optics enabling lower laser induced
focus shift and improved process monitoring
due to increased light efficiency in the
camera port. The control of the RLSK and
its communication with the robot has been
optimized by a modern bus system providing
feedback signals and an output rate of 1 ms.
In addition, the RLSK features a new cross
jet which enables a more flexible mounting
and control of the cross jet.
Three Dimensions
At the Speed of Light
The RLSK uses scanner technology to position
the laser light on the work piece. Two high speed
scanner mirrors and a linear axis (which holds the
collimation module) accurately position and move
the laser focus in a 3D work space of 200 x 300 x
200 mm³ within milliseconds.
The unique optical design of the lens systems
for collimation and focusing of the laser beam
guarantees a constant focus diameter for reliable
process results in the entire work space. The
integrated linear axis moves the focus position
in the Z dimension and positions two additional
laser pointer beams to the laser focus position.
This enables offline and pre-programming of the
welding process with pinpoint accuracy. The laser
welding process can be observed and analysed
online by coupling the imaging system of a CCD
camera to the linear axis of the RLSK.
Easy Process Set-Up
With the RLSK Studio
The RLSK Studio software enables the
user to leverage the capability of remote
laser processing as well as setting up the
entire process in an user friendly way.
The precise positioning of the laser focus
and the process features can easily be
visualized using the RLSK Studio. The
graphical user interface of the RLSK
Studio assists in synchronizing the focus
movement of the RLSK with the motion
sequence of a handling device such as
a robot.
Main Features of RLSK Studio:
• Downloading and uploading of work
pieces or component geometry
•Editing process sequences
•Editing process features such as seam
shapes, welding speed, laser power,
laser power ramping, defocussing etc.
•Visualizing and optimizing the laseron time
•Editing synchronization points and the
optimizing motion sequences
