Compact laser etching device, system and method

摘要

A system, method, and device for etching an indicia onto a substrate includes a compact laser etching device having a delivery head, an emitter housing, a RF cable, and a communication cable. The delivery head has a beam steering mechanism and a hood assembly positioned between the beam steering mechanism and the substrate. The emitter housing has a laser for generating a laser beam, and a fold mirror positioned in an optical path of the laser beam for redirecting the laser beam into the beam steering mechanism. A remote RF electronics package drives the laser. Control electronics cause the beam steering mechanism to steer the laser beam into a pattern of the indicia. The delivery head may further include a plurality of suction cups for holding the compact laser etching device in engagement with the substrate.

1. A system for etching an indicia onto a substrate, the system comprising:
a compact laser etching device comprising:
a delivery head having a beam steering mechanism, and a hood assembly positioned between the beam steering mechanism and the substrate, the hood assembly having a hood member for holding the beam steering mechanism a fixed distance from the substrate;an emitter housing having a laser for generating a laser beam, and a fold mirror positioned in an optical path of the laser beam, the fold mirror for redirecting the laser beam into the beam steering mechanism;a RF cable in electrical communication with the laser; anda communication cable in electrical communication with the beam steering mechanism; an RF electronics package in electrical communication with the RF cable for driving the laser, the RF electronics package located remote from the compact laser etching device; control electronics in electrical communication with the communication cable for causing the beam steering mechanism to steer the laser beam into a pattern of the indicia.
