INFINITE THICKNESS LASER PROCESSING SYSTEM

摘要

A laser material processing system comprises: a housing defining an engraving chamber, an xy laser beam steering system, a non-telescoping focus mechanism, and a camera system that facilitates production of engravings that exceed the xy dimensions of the engraving chamber. The housing includes a removable bottom panel that allows processing of workpieces that exceed dimensions of the engraving chamber. The focus mechanism includes a carriage mirror subassembly, a sliding member moveably attached to the carriage mirror subassembly, and a focusing lens subassembly attached perpendicularly to a lower portion of the sliding member. The carriage mirror subassembly and focusing lens subassembly are configured to receive and focus a laser beam to a focal point. The focusing lens subassembly is adjusted along a z-axis by disengaging the locking component and vertically sliding the sliding member and is locked into a position by engaging the locking component with the sliding member.

1. A laser processing system comprising:
a housing defining an engraving chamber; an xy laser beam steering system located inside the engraving chamber,
the xy laser beam steering system comprisinga first y-axis rail,a second y-axis rail parallel to the first y-axis rail,an x-axis rail perpendicular to both the first y-axis rail and the second y-axis rail, andan x-axis carriage moveably mounted to the x-axis rail; and a non-telescoping focus mechanism comprised of
a carriage mirror subassembly,a sliding member moveably attached to the carriage mirror subassembly, the sliding member comprising a locking component, anda focusing lens subassembly attached to a lower portion of the sliding member wherein the carriage mirror subassembly and the focusing lens subassembly are configured to receive and focus a laser beam to a focal point and wherein the focusing lens subassembly is adjusted along a z-axis of the engraving chamber by disengaging the locking component and vertically sliding the sliding member.
