CO2 laser marking tshuab yog galvanometer -raws li laser npav tshuab uas siv cov pa roj carbon monoxide ua nws qhov nruab nrab. Lub raj xa tawm tau ntim nrog cov pa roj CO2 nrog rau ntau yam khoom siv hluav taws xob- xws li helium thiab nitrogen. Thaum muaj hluav taws xob siab siv rau cov electrodes hauv lub raj xa tawm, lub teeb ci tshwm sim, zoo siab rau CO2 molecules los tsim lub teeb laser infrared nrog lub wavelength ntawm 10.6 μm (los yog 10.64 μm). Lub laser beam generated undergoes lub zog amplification nyob rau hauv ib tug optical resonant kab noj hniav. Tom qab ntawd lub amplified laser beam yog qhia los ntawm galvanometer scanning system los tswj nws txoj kev deflection, thiab tom qab ntawd tsom nrog siab precision mus rau saum npoo ntawm lub workpiece siv F-Theta lens (los yog tsom iav). Lub siab- lub zog laser beam cuam tshuam nrog cov khoom siv- los ntawm kev ua haujlwm thermal (inducing localized heating, melting, or even vaporization) los yog los ntawm kev ua cov txheej txheem txias- los tsim ib lub cim ruaj khov ntawm cov khoom siv.
Raws li cov qauv ntawm cov pa ntws, CO2 laser npav tshuab feem ntau yog categorized rau hauv transverse-flow laser marking machines thiab axial-flow laser marking machines. Transverse-Flow laser marking machines muab lub zog tso zis siab tab sis muaj cov kab teeb qis dua; conversely, axial-flow laser marking machines feature superior beam zoo thiab xa high marking precision.
