Nws yog ib qho heev uas ua rau lub qhov me me nyob hauv kev tivthaiv. Txawm li cas los xij, yog hais tias nws yuav tsum tau thov ntau tus me me qhov ntawm 0.1 hli mus rau ob peb lub microns nyob rau hauv lub cheeb ntawm cov ntaub ntawv tawv, nws yuav tsis yooj yim rau siv cov cuab yeej khiav lag luam me tib yam. Txawm hais tias nws tuaj yeem ua tiav, tus nqi ua haujlwm yuav siab heev. siab. Cov tshuab uas twb muaj lawm siv cov laser txiav micro-qhov ntawm cov khoom siv los ntawm kev ua kom pom los ntawm high-speed rotating me kev xyaum nrog kaum ntawm txhiab tus revolutions ib feeb los yog pua pua txhiab tus revolutions. Feem ntau, tsuas yog qhov me me uas muaj kab uas loj tshaj 0.25 hli tuaj yeem ua tiav los ntawm hom no. Hauv kev lag luam niaj hnub no feem ntau yuav tsum siv lub tshuab qhov me me tshaj qhov no. Piv txwv, nyob rau hauv kev lag luam ntawm cov tshuab hluav taws xob, kev tsim tawm ntawm ntau daim ntawv cog lus Circuit Boards yuav tsum yog cov drilling ntawm txhiab tus me qhov muaj ib txoj kab uas hla ntawm 0.1 txog 0.3 hli.
Obviously, siv cov laum me ntsis xwb hais txog txheej txheem, cov teeb meem yuav tsum muaj cov loj, kev ua zoo tsis yooj yim rau lav, thiab tus nqi ua haujlwm tsis tsawg. Thaum ntxov li xyoo 1960, cov kws tshawb fawb tau siv cov lasers los ua cov qhov me me hauv cov quav hlau hauv qhov chaw kuaj mob. Tom qab ze li ntawm 30 xyoo ntawm kev txhim kho thiab kev loj hlob, nws yog tam sim no tsis muaj teeb meem siv cov lasers los ua me me qhov nyob rau hauv cov khoom. Ua zoo zoo. Cov qhov me me uas tau punched tawm tau tsis tu ncua thiab tsis muaj burrs. Qhov xuas nrawm nrawm yog ceev heev, thiab lub qhov yuav punched txog li ib txhiab ib pliag.
Yog vim li cas lub laser drills lub qhov me me nyob rau hauv cov khoom yog yooj yim heev (tawv ntaub engraving puncher), thiab cov kev xyaum tsis yog nyuab. Lub laser muaj kev sib koom tes zoo thiab muaj peev xwm ua kom pom los ntawm kev kho qhov muag mus rau hauv ib qho chaw me me ntawm lub teeb (tsawg tshaj li 1 micron), uas yog sib npaug "micro drill" rau drilling. Qhov thib ob, qhov ci ntawm lub laser siab heev, thiab qhov laser zog ceev (qhov nruab nrab ntawm ib thaj tsam square centimeter) ntawm qhov tseem ceeb ntawm kev ua kom pom tseeb yog siab. Lub laser tso zis los ntawm ntau hom laser tau tsim rau 109 joules / cm 2. Lub ko taw tuaj yeem ua rau cov khoom siv yaj thiab vaporize, tawm hauv lub qhov me me rau hauv cov khoom thiab cov qauv drilled nrog ib tug laum kev txiav.
Laser cov kws tshawb fawb kuj tau ua ntau txoj kev tshawb fawb txog kev siv laser "drills". Lawv pom tias siv ntau lub teeb ntswg ntawm ib pliag (feem ntau hu ua laser pulses siab heev dua) ua kom "tho ntsis", qhov zoo ntawm lub qhov me yog qhov zoo tshaj ib lub teeb plawv, lossis ob peb lub teeb paug ntawm ob. Lub qhov yog zoo. Yog vim li cas tej zaum qhov no: thaum siv ib lub teeb plawv ib ob los yog ob peb lub pulses, lub laser zog yuav tsum tau rau txhua lub teeb mem hluav yog tus siab, yog li ntawd cov khoom yuav tsum rhuab rau yaj mus ua qhov. Txawm li cas los xij, cov khoom uas tsis muaj hlau yaj tsis muaj vaporization txaus, tab sis heats thiab vaporizes cov khoom hauv nws cheeb tsam. Yog li ntawd, cov qhov me me uas tau punched yog qhov tsis zoo. Yog tias lub teeb plhaws tawm ntawm qhov laser siab, qhov nruab nrab lub zog ntawm txhua lub teeb plawv tsis siab heev, tab sis lub hwj chim tsis txo qis vim qhov dav dav ntawm lub teeb mem tsawg. Yog li, txhua lub laser pulse tsim me me ntawm yaj ntawm cov khoom, mas vaporization. Txij thaum lub tshauv yog tsawg dua thaum cov khoom nyob ze ntawm lub orifice yog rhuab, nws tsis tshwm sim thaum xuas nrig ntaus nrog ib leeg xwb. Cov duab thiab qhov loj ntawm qhov punched qhov yog ntau li niaj zaus.
Thiaj li yuav ua rau qhov zoo tshaj ntawm cov qhov punched siab, nws tseem yog qhov tsim nyog yuav tsum tau them sai sai rau qhov kev xaiv ntawm lub laser kev ua kom pom tseeb txoj hauj lwm. Lub hauv paus ntsiab lus ntawm kev xaiv lub hom phiaj yog roughly tib yam: rau cov ntaub ntawv tuab, qhov tseem ceeb ntawm qhov teeb meem hauv laser yuav tsum muaj nyob rau hauv cov workpiece. Yog tias cov khoom siv nyias, qhov tseem ceeb ntawm txoj hlua laser yuav tsum muab tso rau saum npoo ntawm cov khoom ua haujlwm. Qhov kev hloov no yuav ua rau qhov loj ntawm qhov xuas qhov punched nce thiab nqis yeej zoo ib yam, thiab yuav tsis muaj "qhov chim" qhov.
Drilling qhov nyob rau hauv cov ntaub ntawv nrog ib lub laser, qhov zoo ntawm qhov drilled qhov tsis zoo tsuas yog zoo heev, tshwj xeeb tshaj yog thaum muaj coob tus me me qhov ua, qhov loj thiab cov duab ntawm lub plurality ntawm qhov me me yog ensured, thiab cov drilling ceev yog ceev thiab qhov ua tau zoo dua yog qhov siab. . Yog li, ntxiv rau laser drilling hauv kev lag luam hauv electronics, ntau lwm yam muaj feem xyuam chaw siv, xws li cov qhov me me nyob rau hauv cov cigarette zoo tib yam, cov qhov me me nyob hauv lub tshuab tua tawm, kuj siv cov khoom ua laser. Ob lub thawv nebulizer thiab lub caj dab ntawm lub raj mis muaj qhov ndlwg khiav ceev cov khoom siv (xws li deodorant, oil or other liquid). Qhov ua tiav ntawm lub valve yog txiav txim siab los ntawm lub qhov me me nyob rau hauv lub sprayer. Qhov chaw me me no muaj ib lub cheeb ntawm 10 micrometers rau 40 micrometers. Nws tsis yog zoo li siv lwm hom kev kho tshuab. Nws tuaj yeem ua tiav los ntawm laser kom zoo. Nws tuaj yeem ua si ntawm 40,000 qhov me me ib teev twg.
