Lasit has developed a complete laser system for marking die castings

A few years ago, a German company contacted Lasit to create a complete laser system for laser marking Datamatrix codes and text strings on die castings. The company, which produces Automotive components, requested a complete, high-productivity system that was able to work with robots and verify quality after code marking.
The FlySwap was therefore designed according to these specific requirements and is a marker with a Fiber laser technology, equipped with XYZ axes.
To mask the robot loading time and increase machine productivity, the latter was equipped with a double loading station.
In this way, while marking is in progress on one station, the robot can load the next piece in the free station. These operations are facilitated by the upper pneumatic door, which frees the work area from obstructions so that the robot can position large pieces on the template without any difficulty.

Engraving process
This marker is equipped with an inspection system that is able to perform auto-centering of the pieces to prevent any positioning errors by the robot. The two stations are equipped with sensor that allow the software to recognize the piece and automatically load the correct marking layout.
Another distance sensor automatically focuses so as to manage the height variations of the pieces due to the limits of die-cast printing.
The laser head has a rotation greater than ±100°: this, together with the internal Cartesian axis system, allows us to reach and mark any position in the work area.
Once the laser marking process is completed, the camera checks and performs grading of the marked Datamatrix, the cabin and the head move to the other station and the cycle can start again.
Before concluding, it is worth focusing on the automation potential of this machine, which can easily be placed in a robotic cell.
