Laser head assembly for laser processing system

摘要

The present invention relates to a head assembly for a laser processing system, preferably a fiber laser processing system. An assembly system allows a secure and a slidingly focusing displacement of a focusing lens assembly relative to a beam path in a laser processing system. The assembly system provides easy replacement of desired focusing lens assemblies. Adaptive modifications are operative to provide computerized processor control of the focusing displacement and detection of an installed optical assembly and position thereof.

主权项

1. A head assembly for a laser processing system, comprising:
an operative lens assembly interposed along a beam path of said laser; a monolithic cover plate securing said operative lens assembly in a sealed arrangement with a bounded lens receiver bounding said beam path; an adjustment system operative to adjust said lens assembly along a direction transverse to said beam path in said sealed arrangement therewith, said adjustment system being configured with a first and second pivot arm pivotally secured to said cover plate about a common pivot axis parallel to said beam path; a focus system operative to focus said lens assembly in an axial direction parallel to said beam path in said sealed arrangement; andwherein said lens assembly includes a lens barrel in a relative sliding arrangement with a lens module replaceably securing a lens cell in said beam path said lens barrel being configured with a plurality of sections, andwherein the adjustment system is further configured with a plurality of alignment screws threadedly mounted to respective barrel sections and operable to align said lens barrel relative to said barrel sections along respective pivot arms and parallel to said beam path.
