Traceability Solutions for the Automotive (Laser Marking)

Auto-focus function

Our built in camera makes it possible to perform automatic focusing without the use of any external devices. This makes it possible to mark parts that are not at the same focal distance, and eliminates the need for external tooling. Additional production costs can be kept to a minimum while increasing efficiency and throughput.

* The built-in camera is used to monitor the focal distance using the laser pointer.
Automatic focusing is performed by calculating the focal distance from the pointer position. This measurement may not be possible in some cases due to the material, shape, and surface of the workpiece.

Marking verification

Images are captured by the built-in camera before and after marking in order to verify marking. The contrast differences between the two images are compared and thresholds can be set in order to automate marking confirmation. This, in turn, prevents mis-marking.
