Txij li thaum nruab nrab -1960s, lasers tau siv los ua cim, etching, thiab txiav. Lub ntiaj teb thawj laser npav tshuab tau tsim nyob rau hauv 1965 rau yav tom ntej drilling qhov nyob rau hauv pob zeb diamond manufacturing pwm, thiab cov cuab yeej tom qab tau txais lub zog ceev.
Thaum ntxov qhia txogCO2 lasers rau kev kos npetau tshwm sim hauv xyoo 1967, thiab cov thev naus laus zis tau mus txog kev loj hlob hauv nruab nrab -1970s los ntawm kev lag luam ntawm niaj hnub CO2 laser tshuab. Txij thaum ntawd los, laser npav tshuab tau dhau los ua qhov tseem ceeb hauv ntau qhov kev lag luam los ntawm aerospace mus rau kev tsim khoom siv kho mob, tshuaj, thiab khw muag khoom.
Txawm hais tias muaj kev sib tw nrog lwm cov thev naus laus zis xws li inkjet luam ntawv, lasers tau raug stamped raws li lub zog muaj zog, tsis tshua muaj nqi, thiab rov ua dua tshiab. Qhov tseem ceeb, cov txheej txheem yog eco-friendly thiab yuav tsum tsis muaj consumables (xws li number case, cartridges, thiab ntawv). Tam sim no, laser npav tshuab tsis cia siab rau CO2 lasers lawm; lwm tus, xws li fiber ntau lasers thiab Nd: YAG solid-state teeb qhov chaw, muab cov hneev taw me me, txo tus nqi tu, thiab lwm txoj hauv kev zoo; thiab kev nce qib hauv kev muaj peev xwm thev naus laus zis tau tshwm sim. Kev lag luam ceev tshaj plaws laser npav tshuab tam sim no tuaj yeem ua tiav kaum tawm txhiab qhov hauv ib teev.
Thaum lub evolution ntawm laser npav tshuab tau sai heev, manufacturers thiab cov neeg siv ntawm laser npav tshuab yog tam sim no tab tom nrhiav rau txoj kev tshiab los thawb cov ciam teb ntawm cov cim technology kom tau raws li cov kev cov nyom tshiab thiab txhim kho kev ua tau zoo.
Ceramic Circuit Court Laser npav
Cov kev cov nyom no los ntawm cov ntaub ntawv tshiab los ua tiav, thiab cov ntawv thov tshiab yuav tsum tau ua haujlwm - txhua tus tsav tsheb xav tau kev loj hlob thiab kev tsim kho tshiab thaum tsim kev lag luam rau kev tsim kho laser.
Piv txwv li,ceramicsyog ib qho ntawm cov ntaub ntawv loj tshaj plaws hauv kev ua laser, thiab cov khoom siv no tseem ceeb tshwj xeeb hauv kev tsim cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Feem ntau hu ua "niam ntawm tag nrho cov khoom siv hluav taws xob," cov ntawv luam tawm hluav taws xob (PCBs) yog cov khoom siv hauv txhua yam khoom siv hluav taws xob, thiab cov kev hloov me me hauv PCB kev loj hlob muaj feem cuam tshuam rau kev lag luam kev lag luam.
Nyob rau hauv xyoo tas los no, lub hom phiaj tau hloov mus rau kev siv cov ceramics hauv cov pa luam ntawv Circuit Court boards (PCBs), uas yog tsim los ntawm cov yas epoxy resins xws li FP4. Ceramic circuit boards muab kev kho cua sov zoo, yooj yim rau kev siv, thiab muab kev ua tau zoo dua piv rau cov tsis-ceramic PCBs. Txawm li cas los xij, ntau cov txheej txheem kos npe-xws li kev tshuaj ntsuam xyuas tsis haum rau ceramics. Ink marking ntawm ceramics yog cumbersome, yuav tsum tau ob peb consumables, thiab tsis resistant rau puas. Lub brittleness thiab hardness ntawm ceramics kuj ua rau lawv yog ib qho ntawm cov ntaub ntawv nyuaj rau kos.
Raws li qhov tshwm sim, lasers tau nce mus rau qhov tseem ceeb hauv xyoo tas los no los ua lwm txoj hauv kev siv tshuab luam ntawv, thiab ntau lub tuam txhab laser tau tsim cov tshuab tshwj xeeb rau cov cim cim, xws li diode-pumped solid-state UV lasers, nrog rau cov pa CO2. lasers.
Andrew May, tus thawj coj ntawm lub tuam txhab laser marking tuam txhab hais tias "Qhov no suav nrog cov qauv ntawm kev ua haujlwm me me," hais tias Andrew May. Txawm li cas los xij, nws hais ntxiv tias kev nthuav qhia kev lag luam tshiab yuav siv sij hawm ib yam nkaus, "Puas muaj daim ntawv thov tshiab txhua lub lim tiam? Tsis yog. Tab sis 15 xyoo dhau los, peb yeej tsis tau cim rau cov khoom me me, thiab tam sim no peb ua."
Ntau cov ntaub ntawv hloov tau yooj yim, cov duab, thiab qhov ntau thiab tsawg
Txawm li cas los xij, txawm hais tias nws txoj kev loj hlob sai, ceramic marking hauv electronics tsis yog tam sim no lub tuam txhab laser npav lub lag luam loj tshaj plaws. "Kev lag luam loj tshaj plaws rau peb yog cov khoom siv kho mob," hais tias Andrew May, "tom qab ntawd tsheb, hluav taws xob thiab cov khoom siv hluav taws xob dav dav. Cov khoom lag luam xav tau sib txawv heev nyob ntawm kev lag luam thiab kev lag luam hauv nqe lus nug."
Lub tuam txhab muaj yim lub tshuab laser (tsib tus uas yog Galv-tsav) muab cov kev pabcuam kos npe rau ntau yam kev siv. Vim li no, thiab vim hais tias lub tuam txhab yeej ib txwm tau txais cov neeg siv khoom tshiab nrog cov kev cai bespoke - Tej zaum qhia tias lub peev xwm hloov tau yog qhov tseem ceeb. Yog li ntawd, nws siv lasers haum rau kev kos cov khoom sib txawv, cov duab, thiab qhov ntau thiab tsawg, nrog rau ntau qhov sib txawv. Qhov ntau ntawm cov cim nws tuaj yeem muab tau kuj muaj ntau yam raws li nws cov neeg siv khoom, nrog rau nws cov lasers muaj peev xwm ua tau txhua yam los ntawm cov lej rau cov duab thiab cov ntaub ntawv matrices - tag nrho ntawm kev kub ceev thiab nrog kev tsim tawm siab.
Catering rau qhov kev hloov pauv no yog li qhov tsim nyog rau laser npav tshuab manufacturers xws liBluhm Systeme.
Kev thov rau cov khoom siv traceability tau loj hlob
Lwm qhov tseem ceeb hauv kev lag luam ntawm laser npav yog kev ruaj ntseg thiab kev ua kom zoo ntawm traceability - tus neeg txheeb xyuas cov khoom los ntawm kev siv cov cim cim rau ntawm nws qhov chaw. Cov cim no tuaj yeem siv tau ntau hom, tab sis qhov nrov thiab tseem ceeb yog kev siv cov ntaub ntawv matrices xws li ob-dimensional codes (QR codes).
Los ntawm kev kos ib tus neeg cov khoom nrog nws tus kheej cov ntaub ntawv tshwj xeeb matrix code, nws tuaj yeem txheeb xyuas tau yooj yim hauv txoj kev tsis muaj kev cuam tshuam nrog cov ntsiab lus tseem ceeb xws li chaw tsim khoom, batch tooj, thiab lub neej. Qhov no muab kev ruaj ntseg zoo: cov neeg siv khoom thiab cov neeg siv tuaj yeem txiav txim siab qhov tseeb ntawm cov khoom. Qhov kev lees paub zoo no ua rau muaj kev sib txuas ncaj qha ntawm cov neeg siv khoom thiab cov chaw tsim khoom thiab muab tus nqi ntxiv rau cov khoom, ua rau lawv sib tw nrog cov nqi qis dua. Vim nws qhov tseeb tsis txaus ntseeg, lub laser yog qhov tsim nyog rau kev sau cov lej kom ntxaws me me li 200 μm loj - me me dhau los pom los ntawm ib tus neeg hla, tab sis yooj yim kuaj nrog lub xov tooj smartphone yog tias ib tus neeg paub lawv qhov chaw. Ntawm qhov ntau thiab tsawg, cov ntaub ntawv matrices tuaj yeem siv los tiv thaiv cov khoom cuav, ua kom yooj yim los xyuas qhov tseeb ntawm cov khoom zoo hauv txoj kev tsis muaj kev cuam tshuam. Qhov no muaj kev cuam tshuam loj heev rau kev lag luam kws tshuaj vim nws yog ib txoj hauv kev los xyuas kom meej tias cov tshuaj xws li cov tshuaj tsis raug tsim tawm thiab faib tawm dag zog.
Cheebtsam traceability kuj plays lub luag haujlwm tseem ceeb thaum siv los ua pov thawj hauv kev foob. Piv txwv li, yog tias ib tug neeg muaj kev hloov kho mob thiab kev hloov pauv tsis ua tiav, traceability tso cai rau lawv paub tseeb tias nws mus qhov twg, nws mus qhov twg, thiab nyob rau hauv qhov twg batch nws mus tsis ncaj ncees lawm. Qhov no yeej ua kom muaj txiaj ntsig zoo hauv cov khoom xws li cov khoom rov qab, tab sis nws kuj ua rau cov neeg siv khoom muaj kev ywj pheej ntau dua. Tej zaum nws yuav tsis pom tseeb, tab sis raws li tib neeg xav paub ntau ntxiv txog kev hais plaub, thev naus laus zis uas tuaj yeem txhim kho kev txiav txim plaub ntug yuav tsum tau ua.
Traceability kuj pab txhawb rau lwm qhov sib txawv ntawm kev tsim khoom: txhim kho ib puag ncig kev ruaj ntseg thiab txo cov kev cuam tshuam ecological. Los ntawm kev taug qab ib yam khoom kom paub thaum nws ua tsis tiav, lossis paub thaum nws mus txog qhov kawg ntawm nws lub neej, cov neeg tsim khoom muaj peev xwm ua tau zoo dua los hloov thiab rov ua dua tshiab. Qhov no kuj txhais tau tias cov khoom tuaj yeem xa rov qab rau kev kho dua tshiab raws li tau npaj tseg, yog li cov khoom siv tsawg dua tuaj yeem mus rau hauv qhov chaw pov tseg.
Txawm li cas los xij, tam sim no cov ntaub ntawv matrix labeling tshuab ntsib ntau yam teeb meem. Qee cov ntaub ntawv ua rau kev tuav nyuaj dua - tshwj xeeb yog iav thiab polymers, nrog rau cov hlau nyias thiab foils. Cov cim yuav tsum tau ua kom ruaj khov thiab ruaj khov, thiab lub kaw lus yuav tsum muaj peev xwm ua kom haum rau ntau qhov ntau thiab tsawg ntawm cov khoom.
Ib qho kev sib tw tshwj xeeb rau qee lub tshuab laser npav yog cim rau ntawm qhov chaw uas tsis yog-planar. Cov tshuab luam ntawv inkjet tseem muaj ntau dua cov tshuab laser-raws li hauv cheeb tsam no. Raws li qhov tshwm sim, cov neeg ua haujlwm hauv qhov system tau ua haujlwm los daws cov teeb meem no. Piv txwv li, qee cov tuam txhab ntawm laser npav tshuab muab CO2 thiab fiber ntau lasers nrog lub zog nruab nrab ntawm 20-500 W thiab lub sijhawm sib txawv, nruab nrog nws pib-kho qhov tsom optics siv rau ntawm 3D qhov chaw uas tuaj yeem hloov kho rau qhov curvature ntawm qhov khoom. Txhawm rau suav rau cov chaw uas tsis paub txog geometry, cov tshuab siv lub autofocus tsis pom kev uas thawj zaug luam theej duab 3D nto thiab tom qab ntawd kho lub laser tsom mus rau lub sijhawm kos npe.
Txawm li cas los xij, cov chaw tsis tiaj tus tsis yog tib qho kev sib tw ntsib cov tuam txhab ntawm laser npav tshuab. Dr. Florent Thibaut, CEO ntawm ib lub chaw tsim khoom ntawm laser marking solutions, piav qhia tias, "Nyob rau hauv ntau qhov xwm txheej, cov cim kev daws teeb meem uas yog cov txheej txheem thoob ntiaj teb, xws li inkjet, tsis muaj peev xwm ua tau raws li cov kev xav tau los muab cov cim tshwj xeeb rau txhua yam khoom tam sim no. , kev siv cov lasers ib txwm muaj twb muaj nyob rau hauv txoj kev txuas mus ntxiv, ib yam li siv tus cwj mem. Txawm li cas los xij, qhov no tsis nrawm txaus - peb yuav tsum nrhiav kev daws teeb meem uas sib npaug ntawm cov khoom ntim thiab qhov tseeb. "
Kev sib txuas ua ke yog cuam tshuam vim tias laser npav yuav tsum hloov pauv rau txhua yam khoom, yog li muaj cov cuab yeej cim npe uas tuaj yeem hloov kho rau txhua yam khoom yog qhov tseem ceeb. Cov neeg tsim khoom xav tau cov khoom siv siab heev - cov cim yuav tsum tau hloov kho thiab cov cim cim yuav tsum siab - thiab qhov no tsis txawm xav txog cov teeb meem ntawm kev ua cov khoom xws li iav lossis polymers.
Txhawm rau daws qhov teeb meem no, lub chaw tsim khoom lag luam laser marking daws tau patented nws VULQ1 thev naus laus zis, uas yeej Laser Systems Innovation Award ntawm xyoo no Laser World Photonics Industrial Production Engineering, uas tsis xaiv rau kev siv ib lub teeb nruam ntawm lub teeb (raws li qhov rooj plaub nrog cov pa cim tshuab). Hloov chaw, nws siv ntau pua lub teeb teeb los tsim cov txiaj ntsig zoo li lub cim - tsim tag nrho cov ntaub ntawv matrix code hauv ib qho tam sim. Cov txheej txheem siv los tsim cov ntawv cim tshwj xeeb no yog dynamic beam shaping, uas yog ua tiav siv cov khoom xws li Spatial Light Modulator (SLM), uas tuaj yeem hloov kho ntawm ib qho kev txhaj tshuaj los tsim kab teeb nrog cov qauv tshwj xeeb.
Thaum lwm yam laser marking thev naus laus zis tuaj yeem ua qhov tseem ceeb ntawm qhov kev rov ua dua siab dua rau kev ua haujlwm siab, cov cuab yeej no siv lub zog ntawm cov mem tes ntau dua thiab ua rau tib lub sijhawm kom tau txais txiaj ntsig zoo dua.
Thibaut hais tias, "Lub tswv yim zoo li lub cim cim no qhib lub peev xwm tsim tau zoo heev rau 2D barcode cim thiab yooj yim rau kev siv."
Piv txwv li, nws cov thev naus laus zis tuaj yeem siv los kos cov khoom siv kho mob PVC nrog 570-μm-dav cov ntaub ntawv matrix code ntawm tus nqi ntawm 77,000 ib teev. Lwm cov ntaub ntawv uas lub kaw lus tuaj yeem cim suav nrog txhuas coated nrog HDPE polymer; dej qab zib-txiv qaub iav; borosilicate iav, ntshiab kub, thiab epoxy molded composite.
Thibault ntxiv, "Cov qauv qhov ntau thiab tsawg tuaj yeem ua me me li 100 μm thaum tswj kev nyeem tau zoo kawg nkaus, txawm tias thaum kos rau hauv txoj kab ncaj nraim, vim tias txhua lub cim tau cim ib txhij." Dab tsi ntxiv, vim tias nws tsis tas yuav vam khom siab ntau zaus, thev naus laus zis tuaj yeem tsim cov tshuab siv off-the-shelf infrared thiab ntsuab Nd: YAG lasers nrog repetition zaus ntawm ib ncig ntawm 20-30Hz, kom ntseeg tau tias nws cov tshuab nyob twj ywm raws li tus nqi-zoo li ua tau.
Ultrafast laser hloov iav rau hauv cov ntaub ntawv khaws cia
Lwm qhov chaw tshiab zoo siab ntawm laser npav yog cov ntaub ntawv khaws cia. Cov kws tshawb fawb hais tias lawv tuaj yeem tsim cov ntaub ntawv khaws cia tau zoo los ntawm kev siv ultrafast lasers los encode cov ntaub ntawv rau hauv iav / crystal media. Cov ntaub ntawv khaws cia hauv iav / crystal hauv daim ntawv ntawm micro ablation, thiab ib zaug tsim, nws yuav tuaj yeem khaws cia rau lub sijhawm zoo.
Hauv xyoo 2013,Hitachitshaj tawm nws thawj quartz siv lead ua cov ntaub ntawv khaws cia, thiab hauv 2014, cov kws tshawb fawb ntawm University of Southampton's Optoelectronics Research Center (ORC) tau tshaj tawm lawv txoj kev loj hlob ntawm femtosecond laser-etched iav system. ORC tau pib koom tes nrog Microsoft Kev Tshawb Fawb ntawm "Project Silica" ORC tau pib ua haujlwm nrog Microsoft Kev Tshawb Fawb ntawm "Project Silica," uas tau cog lus tias yuav tsim kho zb-scale cia systems thiab "tsim rov xav txog yuav ua li cas los tsim cov khoom ntim khoom loj.
Kev sau ntawv ntawm iav tsis yog ib txoj haujlwm yooj yim, txawm li cas los xij, thiab cov txheej txheem pulsed UV lossis CO2 laser tshuab tuaj yeem tsim microcracks - cov khoom cua kub ntau dhau tuaj yeem ua rau muaj kev puas tsuaj ntawm cov kub kub. Thaum qhov no tuaj yeem hla los ntawm kev txo cov mem tes zog, nws tsis yog qhov zoo tshaj plaws thaum yuav tsum muaj siab precision. Qhov no yog vim li cas cov kws tshawb fawb tau tig mus rau ultrafast (femtosecond) laser tshuab kom txo qis kev pheej hmoo ntawm thermal puas. Lub sijhawm luv luv ntawm lub siab-lub zog mem tes kom ntseeg tau tias lub zog txaus xa mus rau cov khoom siv los kos nws nrog qhov tseeb, tsim tsuas yog cov cheeb tsam uas muaj cua sov tsawg thiab tsis txhob muaj microcracks.
Qhov kev txwv tam sim no ntawm cov thev naus laus zis no yog qhov tsis tshua muaj kev ceev ntawm cov ntaub ntawv sau, thiab sau Tb-scale cov ntaub ntawv tuaj yeem siv sijhawm ntau xyoo los ua kom tiav. Ua tsaug, kev ua tsis tu ncua yog qhia txoj hauv kev los ua kom cov ntaub ntawv sau nrawm. Xyoo tas los, ORC cov kws tshawb fawb tau luam tawm ib txoj hauv kev siv hluav taws xob siv hluav taws xob laser hauv phau ntawv xov xwm Optica: tsis yog txoj kev no nrawm, tab sis nws tuaj yeem khaws txog 500 Tb ntawm cov ntaub ntawv ntawm CD-loj silica discs - lawv yog 10, 000 lub sij hawm denser dua Blu-duab tshav Disc cia tshuab.
Cov kws tshawb fawb txoj kev tshiab siv 515 nm fiber ntau laser nrog qhov zaus ntawm 10 MHz thiab lub sijhawm mem tes ntawm 250 fs los tsim cov pits me me hauv silica iav, uas muaj cov qauv nanolaminar ib leeg ntsuas 500 × 50 nm. Cov nanostructures high-density no tuaj yeem siv rau kev khaws cov ntaub ntawv kho qhov muag mus ntev. Cov kws tshawb fawb tau ua tiav qhov kev sau nrawm ntawm 1,000,000 voxels ib ob, uas yog sib npaug rau sau txog 225 KB ntawm cov ntaub ntawv (ntau tshaj 100 nplooj ntawv ntawm cov ntawv) ib ob.
Txoj kev tshiab tau siv los sau 5GB ntawm cov ntawv nyeem rau hauv silicon iav disk qhov loj ntawm CD-ROM ib txwm muaj ze li 100% kev nyeem ntawv raug. Txhua lub voxel muaj plaub cov ntaub ntawv, nrog txhua ob lub suab sib raug rau ib lub cim ntawv. Siv qhov kev sau ceev uas muab los ntawm txoj kev, lub disc yuav tuav tau 500 Tb ntawm cov ntaub ntawv. Los ntawm kev txhim kho cov txheej txheem rau kev sau ntawv sib npaug, nws yuav tsum muaj peev xwm sau cov ntaub ntawv ntau li ntawm 60 hnub, cov kws tshawb fawb tau hais.
