Assisting process devices (autofocus)

The RemoWeld project aimed to an extended, sustainable and competitive use of remote laser welding systems promoting the development of competitive manufacturing procedures. CRF has been involved in the realisation of the autofocus prototype. CRF after preliminary tests has realised the prototype.

The prototype employs:
- CCD camera mounted in front off the remote black box;

- Two laser He-Ne mounted in front off the focussing lens;

- The acquisition system.

Two spots He-Ne laser are coincident in the focus position and during the len movement the spots increases or decreases the distance. The software evaluated in real time the spot distance (z position) and optimised the focus position onto the workpiece.
