Patent number: 11536956Abstract: A multi-beam laser processing system comprising a plurality of laser beams and a plurality of pairs of selectively rotatable mirrors for laser beam steering where each laser beam is independently steered by one pair of selectively rotatable mirrors. The plurality of pairs of mirrors are positioned adjacent to one another within a single main body. The main body is positioned directly opposing the beams, the mirrors directing each laser beam simultaneously to a selected location on a substrate. The main body comprises a plurality of vents; a plurality of passages; a plurality of openings; and a plurality of galvos nested densely within the main body. The galvos direct multiple laser beams to a substrate wherein the fields of view overlap and the laser beam focal point remains small and precise.Type: GrantFiled: November 17, 2014Date of Patent: December 27, 2022Assignee: PRECO, LLCInventors: Daniel B.

Patent number: 11027365Abstract: A laser beam trimming and redirecting device having an aperture therein, the aperture defined by a inner beveled surface for focusing the laser beam directed therethrough and the aperture having an outer beveled surface, or beveled edge, for trimming the laser beam and reflecting the excess energy back towards a source at an angle other than 180 degrees. A reflection capture device positionable upstream of the trimming and redirecting device is configured to absorb the reflected energy instead of the laser beam source or delivery components. The capture device is a liquid cooled device so as dissipate the heat energy absorbed preventing degradation of the device.Type: GrantFiled: July 30, 2018Date of Patent: June 8, 2021Assignee: PRECO, INC.Inventors: James J.

Patent number: 8785811Abstract: Systems and methods are described for efficient laser processing of a moving web-based material. In one embodiment, a moving web is provided at a selected speed. A laser beam is generated having a focal point positioned to provide either a score or cut in the web. The focal point of the laser beam is moved at a speed less than the selected speed for a selected distance thereby producing a discreet score or cut in the web in the machine direction. The focal point is repositioned to form another discreet score or cut once the prior discreet score or cut is formed. The repositioned focal point is moved at a speed less than the selected speed for another selected distance. The step of repositioning is repeated to form a plurality of discreet scores or cuts in the web moving at the selected speed. The laser beam is therefore able to be generated using less power than would be needed to produce the same type of discreet score or cut if the focal point were stationary as the web is moved at the selected speed.Type: GrantFiled: September 28, 2010Date of Patent: July 22, 2014Assignee: Preco, Inc.Inventors: James J.
