Laser npav yog dav lees paub tias yog txoj kev ntseeg siab tshaj plaws, huv si, thiab ruaj khov rau kev txheeb xyuas cov khoom hauv kev tsim khoom niaj hnub. Txawm li cas los xij, rau ntau tus neeg saib xyuas kev yuav khoom, cov txheej txheem tiag tiag ntawm lub laser kos duab micro- tus cwj pwm ntawm blistering speeds tuaj yeem zoo li khawv koob.
Txhawm rau pab cov neeg siv kev lag luam nkag siab txog thev naus laus zis tom qab lawv cov cuab yeej siv, OMA JET muab kev nkag siab hauv - qhov tob saib ntawm lub hauv paus physics thiab core mechanical components of professional laser marking systems.
1. Kev Tshawb Fawb ntawm Beam: Stimulated Emission
Lo lus "LASER" yog lub ntsiab lus rauLub teeb Amplification los ntawm Stimulated Emission ntawm Radiation. Tsis zoo li cov qauv teeb pom kev zoo (xws li lub teeb pom kev zoo) uas emit tawg, ntau - cov xim tsis muaj xim, lub laser ua rau lub teeb teeb uas yog monochromatic (ib lub wavelength tshwj xeeb), coherent (nthwv dej nyob rau theem), thiab collimated (nthwv dej taug kev hauv txoj kev nruj, sib npaug).
Txhawm rau tsim cov kab teeb ci tshwj xeeb no, peb lub ntsiab lus tseem ceeb yuav tsum muaj:
Active Medium:Qhov no tuaj yeem yog cov pa roj (xws li CO2), cov khoom siv - lub xeev siv lead ua, los yog doped optical fiber. Nws txiav txim siab lub wavelength ntawm lub laser.
Lub zog Source (Pumping):Lub zog hluav taws xob lossis lub teeb pom kev zoo tau muab tso rau hauv qhov nruab nrab nquag, ua rau nws cov atoms mus rau lub zog siab dua.
Optical Resonator:Daim iav muab tso rau ntawm ob qho kawg ntawm qhov nruab nrab thaws cov photons tawm rov qab thiab tawm mus, nthuav lub teeb kom txog thaum nws khiav los ntawm ib feem ntawm daim iav raws li lub teeb pom kev zoo, khaus laser.
2. Nkag siab Wavelengths: Fiber, CO2, thiab UV
Yog vim li cas cov lasers sib txawv cim cov khoom sib txawv nyob rau hauv lub electromagnetic wavelength. Cov ntaub ntawv sib txawv nqus lub teeb lub zog ntawm cov spectrum tshwj xeeb:
Fiber Lasers (Wave Length: 1064nm):Ua haujlwm nyob ze -infrared spectrum, fiber ntau lasers siv qhov nruab nrab ntawm cov fiber ntau optical doped nrog tsawg - ntiaj teb cov ntsiab lus. Cov hlau thiab cov polymers nyuaj muaj qhov tshwj xeeb tshaj plaws ntawm kev nqus ntawm 1064nm, tso cai rau lub laser kom sai vaporize lossis kos rau saum npoo.
CO2 Lasers (Wave Length: 10.6μm):Kev khiav hauj lwm hauv qhov deb -infrared spectrum, qhov nruab nrab ua haujlwm yog cov pa roj carbon dioxide sib tov. Tsis yog- cov khoom siv hlau thiab cov organic (xws li ntoo, duab los qhia, iav, thiab PET yas) nqus tau qhov ntev wavelength zoo kawg nkaus, ua rau cov thermal evaporation hauv ib cheeb tsam uas tsim cov nkig, huv si.
UV Lasers (Wavelength: 355nm):Kev ua haujlwm hauv ultraviolet spectrum, UV lasers yog tsim los ntawm kev dhau ib qho khoom siv -lub xeev laser los ntawm cov zaus tshwj xeeb -tripling crystals. Vim tias 355nm photons muaj lub zog loj, lawv ua "daim duab-ablation" lossis "txias cim" los ntawm kev tawg ncaj qha molecular bonds yam tsis muaj cua sov, ua rau lawv zoo tagnrho rau ultra- cov substrates ilv.
3. Kev Taw Qhia Beam: Galvanometer (Galvo) Scanning Technology
Lub laser qhov chaw generates ib tug zoo li qub, ncaj beam ntawm lub teeb. Txhawm rau txhais cov kab no rau hauv cov ntawv nyuaj, cov lej lej, thiab cov lej 2D, lub kaw lus siv ib qhoGalvanometer scanner(feem ntau hu ua "galvo").
Lub tsev galvo muaj ob lub siab -ceev, precision motors nruab nrog micro- daim iav.
X-Axis Daim iavcheb lub laser beam horizontally.
Y-Axis Daim iavcheb lub laser beam vertically.
Los ntawm kev sib koom tes ntawm ob daim iav no los ntawm cov ntawv tswj hwm qib siab digital, lub kaw lus tuaj yeem cheb qhov chaw tsom mus rau laser thoob plaws qhov chaw cim ntawm qhov nrawm mus txog ntau txhiab millimeters ib thib ob, ua tiav microscopic repeatability thiab flawless taug qab ntawm cov kab ntau lawm.
4. Lifespan thiab Thermal Management
Kev lag luam laser markers yog tsim rau hnyav-lub luag haujlwm, ntau- hloov chaw tsim khoom. Khoom-lub xeev laser qhov chaw (xws li cov hauv OMA JET's Fiber systems) yog qhov ruaj khov heev, muab lub neej ua haujlwm ntev tshaj100,000 teevntawm nruam marking.
Yuav kom tswj tau qhov kev ua neej ntev thiab tiv thaiv kev sib tw wavelength, kev tswj xyuas thermal zoo tau muab tso rau hauv lub chassis. Siab - lub zog siv hluav taws xob zoo siv huab cua zoo - cov qauv cua txias lossis cov kua dej - cua txias los ua kom cov cua sov tau zoo, ua kom lub laser kab noj hniav nyob ruaj khov nyob rau hauv kev ua haujlwm tas li yam tsis tas yuav tsum muaj kev saib xyuas tas li lossis kev tuav tuav.
