Laser tu tshuab yog ib tug ua tiav daim ntawv thov ntawm laser technology nyob rau hauv engineering teb. Nws lub hauv paus ntsiab lus yog siv lub zog siab ceev ntawm laser los cuam tshuam nrog cov kab mob uas txuas nrog rau lub hauv paus ua haujlwm kom ua rau lub sijhawm thermal expansion, melting, gas volatilization, thiab lwm yam. Cov kab mob kis tau los ntawm lub hauv paus workpiece. Laser tu tshuab muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob, thiab tau ua tiav kev siv lub log pwm tu, tshem tawm lub cev pleev xim rau lub dav hlau, kev coj noj coj ua relic thiab lwm yam.
Kev tu cov cuab yeej siv niaj hnub suav nrog kev sib txhuam kev sib txhuam (sandblasting, kev siv phom tua hluav taws kub siab, thiab lwm yam), tshuaj tua kab mob, tshuaj ntxuav ultrasonic, ntxuav dej khov qhuav, thiab lwm yam. los ntawm kev xaiv ntawm abrasive nrog sib txawv hardness tuaj yeem ntxuav cov hlau paj ntaub, hlau nto burrs, conformal txheej rau saum npoo ntawm lub rooj tsavxwm Circuit Court, thiab lwm yam. Tshuaj txhuam hniav tu tshuab yog dav siv hauv cov khoom siv saum npoo roj nplai tu, boiler nplai tu, roj pipeline tu. thiab lwm yam teb. Txawm hais tias cov thev naus laus zis no tau tsim thiab ua kom tiav, tseem muaj qee qhov teeb meem, xws li sandblasting tu yooj yim ua rau muaj kev puas tsuaj rau qhov chaw kho, tshuaj txhuam hniav ntxuav yuav ua rau muaj kuab paug ib puag ncig, thiab kev kho tsis zoo yuav ua rau kev tu lub ntsej muag corrosion.
Qhov tshwm sim ntawm laser tu tshuab yog ib lub kiv puag ncig hauv kev tu tshuab. Laser tu tshuab siv qhov zoo ntawm laser xws li lub zog ceev ceev, siab precision, thiab kev sib kis tau zoo. Muab piv nrog cov cuab yeej tu ib txwm siv, nws muaj qhov zoo ntawm kev tu kom zoo, kev tu kom raug, ntxuav qhov chaw, thiab lwm yam, thiab tuaj yeem zam tau cov teeb meem los ntawm kev tu technologies xws li tshuaj txhuam hniav tu. ib puag ncig muaj kuab paug thiab yuav tsis ua kev puas tsuaj rau lub substrate.
Txoj cai ntawm laser ntxuav
Yog li dab tsi yog laser ntxuav? Laser tu yog txheej txheem ntawm kev tshem tawm cov khoom los ntawm cov khoom (lossis qee zaum ua kua) qhov chaw los ntawm kev raug rau lub teeb laser. Thaum tsis tshua muaj laser fluence, cov khoom yog rhuab los ntawm absorbed laser zog thiab evaporates los yog sublimes. Thaum siab laser fluence, cov khoom siv feem ntau hloov mus rau hauv cov ntshav. Feem ntau, kev tu lub laser cuam tshuam nrog kev tshem tawm cov khoom siv nrog lub laser pulsed, tab sis yog tias lub laser siv siab txaus, lub teeb yoj laser txuas ntxiv tuaj yeem siv los ua kom cov khoom siv. Sib sib zog nqus ultraviolet excimer lasers yog tsuas yog siv rau photoablation. Lub laser wavelength siv rau photoablation yog kwv yees li 200nm. Qhov tob ntawm lub zog laser yog absorbed thiab tus nqi ntawm cov khoom tshem tawm los ntawm ib tug tib lub laser mem tes nyob ntawm seb lub optical zog ntawm cov khoom, raws li zoo raws li lub laser wavelength thiab mem tes ntev. Tag nrho cov huab hwm coj ablated los ntawm lub hom phiaj ib laser mem tes feem ntau hu ua tus nqi ablation. Laser radiation yam ntxwv xws li laser beam, scanning ceev thiab scan kab kev pab cuam yuav ho cuam tshuam rau ablation txheej txheem.
Daim ntawv thov ntawm laser tu tshuab
(1) Semiconductor teb
Semiconductor wafers thiab optical substrates muaj cov txheej txheem tib yam hauv cov txheej txheem ua, uas yog, cov khoom siv raw yog ua tiav rau hauv cov duab uas yuav tsum tau ua hauv daim ntawv txiav, sib tsoo, thiab lwm yam. Hauv cov txheej txheem no, cov pa phem tau qhia, uas nyuaj rau tshem tawm. thiab rov ua pa phem yog ib qho teeb meem loj. Cov kab mob nyob rau saum npoo ntawm semiconductor wafers yuav cuam tshuam qhov zoo ntawm Circuit Court board luam ntawv, yog li shortening lub neej kev pab cuam ntawm semiconductor chips. Cov kab mob nyob rau saum npoo ntawm cov khoom siv kho qhov muag yuav cuam tshuam rau qhov zoo ntawm cov khoom siv kho qhov muag thiab cov txheej txheej, uas yuav ua rau lub zog tsis sib xws thiab ua rau lub neej ua haujlwm luv. Vim hais tias laser qhuav tu yog ib qho yooj yim ua rau deg puas tsuaj rau lub substrate, txoj kev tu no yog tsis tshua muaj siv nyob rau hauv lub tu ntawm semiconductor wafers thiab optical substrates, thiab laser ntub tu thiab laser-plasma shock yoj ntxuav muaj ntau yam kev siv nyob rau hauv daim teb no. Qee cov kws tshawb fawb tau kawm txog qhov tso tawm ntawm micron-theem tshwj xeeb enamel rau ntawm qhov chaw ntawm ultra-smooth optical substrate ua ib zaj duab xis dielectric, thiab tom qab ntawd siv lub laser pulsed los ntxuav nws, thiab cov nyhuv tu tau zoo. Txawm hais tias qhov impurity hais ib cheeb tsam ib cheeb tsam tau nce, qhov impurity particle loj thiab qhov chaw npog ob qho tib si txo qis. Txoj kev no tuaj yeem ua kom zoo huv si micron-theem cov pa phem ntawm qhov chaw ntawm ultra-smooth optical substrate.
(2) Cov khoom siv hlau
Piv nrog rau kev ntxuav ntawm semiconductor wafers thiab optical substrates, kev ntxuav cov pa paug ntawm cov ntaub ntawv hlau yog nyob rau hauv qeb macro. Cov pa phem nyob rau saum npoo ntawm cov ntaub ntawv hlau yog tsuas yog oxide txheej (xeb txheej), xim txheej, txheej, lwm yam txuas, thiab lwm yam. inorganic pollutants (xws li xeb txheej). Kev ntxuav cov kuab paug rau saum npoo ntawm cov ntaub ntawv hlau yog tsuas yog ua kom tau raws li qhov yuav tsum tau ua ntawm kev ua tom ntej lossis siv. Piv txwv li, oxide txheej txog 10μm tuab ntawm qhov chaw ntawm titanium alloy yuav tsum tau muab tshem tawm ua ntej vuam, thiab cov xim qub txheej ntawm daim tawv nqaij yuav tsum tau muab tshem tawm thaum lub dav hlau overhaul los pab daws cov tshuaj rov qab. Cov roj hmab log pwm yuav tsum tau ntxuav tsis tu ncua kom huv si ntawm qhov chaw thiab xyuas kom zoo ntawm cov khoom thiab lub neej ntawm cov pwm. Qhov kev puas tsuaj ntawm cov ntaub ntawv hlau yog siab dua li lub laser tu qhov pib ntawm nws cov pa phem, thiab kev tu kom zoo tuaj yeem ua tiav los ntawm kev xaiv lub hwj chim laser, uas tau loj hlob hauv qee qhov chaw.
(3) Teb ntawm kab lis kev cai relics
Vim lawv cov keeb kwm ntev, cov kab lis kev cai hlau thiab cov pob zeb kab lis kev cai relics yuav muaj cov kab mob xws li plua plav thiab number case stains ntawm lawv qhov chaw. Cov kab mob no yuav tsum tau muab ntxuav kom rov qab kho cov kab lis kev cai. Thaum daim ntawv xws li calligraphy thiab painting yog khaws cia tsis raug, pwm yuav loj tuaj rau ntawm qhov chaw thiab daim ntawv plaque. Cov plaques no cuam tshuam rau qhov zoo li qub ntawm daim ntawv, tshwj xeeb tshaj yog rau cov ntawv uas muaj kev coj noj coj ua lossis keeb kwm muaj txiaj ntsig, uas yuav cuam tshuam rau nws txoj kev txaus siab thiab kev tiv thaiv. Qee cov kws tshawb fawb tau kawm txog qhov ua tau ntawm UV laser ntxuav ntawm pwm plaques ntawm daim ntawv nplej. Cov txiaj ntsig kev sim tau pom tias siv lub laser nrog lub zog ntom ntom ntawm 3.2 J / mm2 los luam theej cov plaques tuaj yeem tshem tawm cov plaques nyias ib zaug, thiab luam ob zaug kom tshem cov plaques. Ntxuav, tab sis yog tias lub zog laser siv siab dhau lawm, nws yuav ua rau cov ntawv nplej puas thaum tshem cov quav hniav.
Peroration
Laser tu tshuab yog ib qho kev siv thev naus laus zis, uas muaj cov kev tshawb fawb dav dav thiab cov ntawv thov kev cia siab hauv aerospace, cov cuab yeej siv tub rog, hluav taws xob thiab lwm yam kev tshaj lij. Tam sim no, laser tu tshuab tau paub tab nyob rau hauv ib co teb, ua tsaug rau nws cov high efficiency, ib puag ncig-phooj ywg, zoo tu nyhuv thiab lwm yam ntxwv, nws daim ntawv thov teb kuj maj mam expanding. Txoj kev loj hlob ntawm laser tu tshuab tsis tau tsuas yog paub tab nyob rau hauv lub tshav pob ntawm cov xim tshem tawm, xeb tshem tawm thiab lwm yam kev siv, tab sis kuj muaj cov lus ceeb toom ntawm kev siv laser los ntxuav cov oxide txheej nyob rau saum npoo ntawm cov hlau nyob rau hauv xyoo tas los. Kev nthuav dav thiab daim ntawv thov ntawm cov teb uas twb muaj lawm thiab cov teb tshiab yog lub hauv paus rau kev txhim kho laser tu tshuab. Kev tshawb fawb thiab kev tsim cov cuab yeej siv laser tshiab thiab kev tsim cov cuab yeej siv laser tshiab yuav sib txawv thiab tsim ntau yam haujlwm. Nyob rau hauv lub neej yav tom ntej, tag nrho tsis siv neeg laser tu kuj tuaj yeem ua tiav los ntawm kev koom tes nrog kev lag luam robots.
