Laser Processing Heads

Laser Processing Head RLSK

As a pioneer of the third dimension, the laser processing head RLSK sets new efficiency standards for laser welding. The 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.

 

 

Function

The Optics of 3D Precision

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-programing 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.

 

NEW
The RLSK features now a new vision system with high precision seam tracking capabilities that enable filet welds, which, compared to conventional overlap welds, save material and produce vehicles that are lighter and therefore more fuel efficient. The combination of precision, working range, and speed delivers high quality welds that can be produced in any direction at the rapid rate of more than 10 meters per minute, the fastest ever for the RLSK.

  • Now with 2x faster scanners for faster focus positioning
  • Superior weld quality due to f-Theta technology
  • Extended software suite with new features and enhanced robot communication
  • More options for process observation available

Optional seam tracking feature for full position control

  • 360° omni-directional
  • "Welding on the fly" across the entire workspace
  • High processing speeds of more than 10 m/min


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 laser-on time
  • Editing synchronization points and the optimizing motion sequences
