Muaj laser tu yog txheej txheem ntawm kev tua ib tug laser beam ntawm ib tug khoom nto kom tshem tawm cov pliaj yam khoom. Txij li thaum tus nqi ntawm cov fiber ntau laser tau poob qis hauv lub laser ob peb xyoos, cov laser ntxuav tau ntsib ntau thiab ntau qhov kev xav tau ntawm kev lag luam thiab cov kev cia siab, xws li ntxuav cov txheej txheem txhaj tshuaj molding, tshem tawm cov yeeb yaj kiab nyias lossis qhov chaw zoo li roj, thiab roj, thiab ntau ntxiv. Hauv tsab xov xwm no, peb yuav hais txog cov ncauj lus hauv qab no:

Laser ntxuav yog dab tsi?
Kev lig kev cai, kom tshem tawm xeb, xim, oxide, thiab lwm yam kab mob los ntawm cov hlau nto, kev tu txhua yam, tshuaj ntxuav, los yog ultrasonic tu yuav siv tau. Daim ntawv thov ntawm cov txheej txheem no yog heev txwv nyob rau hauv cov nqe lus ntawm ib puag ncig thiab siab precision yuav tsum.
Nyob rau hauv lub 80s, cov kws tshawb fawb pom tau hais tias thaum illuminating lub rusted nto ntawm cov hlau nrog high-concentrated laser zog, cov irradiated tshuaj muaj ib tug complex ntawm lub cev thiab tshuaj tej yam kev mob xws li kev co, melting, sublimation, thiab combustion. Yog li ntawd, cov khoom paug raug tshem tawm ntawm cov khoom siv nto. Txoj kev tu yooj yim no tab sis muaj txiaj ntsig zoo yog kev tu laser, uas tau maj mam hloov cov kev tu ib txwm nyob hauv ntau qhov chaw nrog ntau qhov zoo ntawm nws tus kheej, qhia dav dav rau yav tom ntej.
Cov tshuaj ntxuav laser ua haujlwm li cas?
Lub laser ntxuav yog ua los ntawm plaub qhov chaw: lubfiber ntau laser qhov (nruam los yog mem tes laser), tswj board, handheld laser phom, thiab qhov kub thiab txias dej chiller. Lub laser ntxuav tswj pawg thawj coj ua raws li lub hlwb ntawm tag nrho lub tshuab thiab muab qhov kev txiav txim rau fiber ntau laser generator thiab handheld laser phom.
Fiber laser generator tsim high-concentrated laser lub teeb uas yog dhau los ntawm cov conduction nruab nrab Fiber mus rau handheld laser phom. Lub scanning galvanometer, xws li uniaxial lossis biaxial, sib sau ua ke hauv cov phom laser qhia lub teeb lub zog rau cov av txheej ntawm cov khoom ua haujlwm. Nrog rau kev sib xyaw ua ke ntawm lub cev thiab tshuaj lom neeg, cov xeb, xim, greasy av, txheej txheej, thiab lwm yam kab mob raug tshem tawm yooj yim.
Cia peb mus rau hauv kev nthuav dav ntxiv txog cov txheej txheem no. Cov kev cuam tshuam nyuaj cuam tshuam nrog kev sivlaser mem tes vibration, thermal expansionntawm irradiated hais,molecular photodecompositiontheem hloov, los yoglawv qhov kev sib koom ua kekom kov yeej lub zog khi ntawm cov av thiab qhov chaw ntawm lub workpiece. Lub hom phiaj cov ntaub ntawv (cov txheej txheej saum npoo yuav tsum tau muab tshem tawm) yog rhuab sai sai los ntawm absorbing lub zog ntawm lub laser beam thiab ua tau raws li qhov yuav tsum tau ntawm sublimation kom cov av los ntawm nto disappears mus cuag cov txiaj ntsig ntawm kev ntxuav. Vim li ntawd, lub substrate nto absorbs ZERO lub zog, los yog lub zog me me, lub teeb fiber ntau yuav tsis ua rau nws puas.

Peb Cov Lus Teb Ntawm Laser Ntxuav
1. Sublimation
Cov tshuaj muaj pes tsawg leeg ntawm cov khoom siv hauv paus thiab cov kab mob sib txawv yog qhov sib txawv, thiab yog li qhov nqus ntawm lub laser. Lub hauv paus substrate qhia txog ntau tshaj 95% ntawm lub teeb laser tsis muaj kev puas tsuaj, thaum cov khoom paug absorbs feem ntau ntawm lub zog laser thiab ncav cuag qhov kub ntawm sublimation.
2. Thermal Expansion
Cov pa phem uas nqus cov thermal zog thiab nthuav dav mus rau qhov chaw tawg. Qhov cuam tshuam ntawm qhov tawg tau kov yeej lub zog ntawm adhesion (lub zog ntawm kev sib txawv ntawm cov khoom sib txawv), thiab yog li cov pa phem yog cais tawm ntawm qhov chaw ntawm cov hlau. Vim tias lub sijhawm laser irradiation luv luv, nws tuaj yeem ua qhov nrawm nrawm ntawm qhov cuam tshuam rau lub zog tawg, txaus los muab kev nrawm txaus ntawm cov khoom zoo kom txav los ntawm cov khoom siv hauv paus adhesion.
3. Laser mem tes vibration
Lub pulse dav ntawm lub laser beam yog qhov nqaim, yog li qhov rov ua haujlwm ntawm lub mem tes yuav tsim ultrasonic kev co los ntxuav lub workpiece, thiab qhov poob siab yoj yuav tawg cov pa phem.
Qhov zoo ntawm Fiber Laser Ntxuav Tshuab
Vim tias kev ntxuav laser tsis tas yuav muaj cov tshuaj hnyav lossis lwm yam khoom siv, nws yog ib puag ncig tus phooj ywg, muaj kev nyab xeeb rau kev khiav lag luam, thiab muaj ntau yam zoo:
✔Solider hmoov feem ntau yog cov khib nyiab tom qab ntxuav, ntim me me, thiab yooj yim los sau thiab rov ua dua
✔Cov pa luam yeeb thiab tshauv tsim los ntawm fiber ntau laser yog ib qho yooj yim kom tso tawm los ntawm cov fume extractor, thiab tsis nyuaj rau tib neeg noj qab haus huv.
✔Kev ntxuav tsis sib cuag, tsis muaj cov khoom seem, tsis muaj kuab paug thib ob
✔Tsuas yog ntxuav lub hom phiaj (xeb, roj, xim, txheej), yuav tsis ua rau lub substrate nto
✔Kev siv hluav taws xob tsuas yog siv xwb, tus nqi khiav qis, thiab tus nqi tu
✔Haum rau qhov nyuaj-rau-mus txog qhov chaw thiab complex artifact qauv
✔Tsis siv neeg laser tu neeg hlau yog xaiv tau, hloov cov khoom siv dag zog
Txhawm rau tshem tawm cov kab mob xws li xeb, pwm, xim, daim ntawv lo, polymers, yas, lossis lwm yam khoom siv saum npoo av, cov txheej txheem ib txwm siv - xov xwm blasting thiab tshuaj etching - yuav tsum tau tshwj xeeb tuav thiab pov tseg ntawm cov xov xwm thiab tuaj yeem ua rau muaj kev phom sij heev rau ib puag ncig thiab cov neeg ua haujlwm. qee zaum.
