Hauv cov pob zeb zom zaws ntau lawm, ib thaj chaw loj yuav tsum tau muaj qhov siab ntawm kev daws teeb meem. Lub voj voog ua haujlwm ntawm cov luam ntawv rau tus menyuam yuav tsum muaj kev koom tes zoo ntawm ntau cov square meters hauv micrometer precision hauv ib lub sijhawm luv luv. Daim ntawv thov ntawm cov lasers hauv daim teb no muaj cov yeeb yam nram qab no: kev ua cov neeg ua haujlwm siab, kev ncaj ncees thiab cov tes taws. Direct laser micro-structuring tshuab yog hloov cov tswv yim kev ua zauv yooj yim (xws li mechanical engraving nrog ib lub pob zeb diamond los yog tshuaj lom neeg ua haujlwm) vim muaj qhov muaj zog dua, rov ua dua, yooj, thiab tsim tau.
Lub pob zeb ua teb tuaj yeem muaj ib hom tsom iav los yog khes qes khib nyiab. Cov duab cov duab yog muab sau rau hauv lub hlwb me me hauv ib txheej tooj liab los sis cov txheej xuav uas hloov mus rau hauv cov duab kos (saib daim duab 1). Ib txheej nyias ntawm chrome saib xyuas lub neej ntev ntawm xovxwm nyob rau hauv kev sib tsoo loj heev. Los ntawm kev siv ib tus kws kho mob, nws yog ensured tias tsuas yog tus nqi ntawm tus cwj pwm txiav txim los ntawm qhov luaj li cas ntawm cov qe ntshav sib kis tau.
Lub pob zeb loj gravure muaj qhov ntev ntawm 0.3 mus rau 4.4 meters, ib ncig ntawm 0.3 mus 2.2 meters, thiab ib cheeb tsam ntawm li 10 square metres. Thaum cov lus daws teeb meem yog 60 mus txog 400 kab / cm, cov naj npawb ntawm cov nruas feem ntau yog 108 txog 1010. Yuav kom ua cov duab ua lag luam hauv lub sijhawm pheej yig tshaj, lub laser yuav tsum muaj qhov siab plhom repetition thiab siab nruab nrab zog.
Rau cov loj-scale micro-engraving nyob rau hauv daim ntawv ntawm thermal ablation, qhov zoo tshaj plaws txoj kev yog siv ib tug pulsed nqaj hlau nrog ib laser pulse mus tsim ib lub xov tooj ntawm tes. Ib qho Q-Hloov Nd: YAG laser system nrog nruab nrab kev khiav hauj lwm muaj zog ntawm 500 watts thiab repetition tus nqi ntawm 70 kHz (saib Daim Duab 3) ua rau lub ntim ablation feem ntawm zinc mus txog 1 cm3 / min thiab thaj tsam ablation feem ntawm 0.1 m2 / feeb. Qhov zoo ntawm lub cell yog txiav txim siab los ntawm kev siv lub zog ntawm tus laser nqaj hlau.
Ib nrab ntawm autotypical hlwb (qhov tob thiab inch yog sib txawv hauv grayscale) tau tsim los ntawm lasers nrog Gaussian beam waveforms, whereas cov hlwb (nrog rau cov depths ntawm ib tus nqi grey) yog tsim los ntawm kev siv cov hauv qab daig hauv qab (saib daim duab 2). Qhov loj ntawm lub hlwb yog nyob ntawm lub zog pulse thiab yog tswj los ntawm cov duab digital teeb uas tau teev los ntawm kev siv ib qho kev siv tshuab hlwb hlau. Ib txoj kab uas siv los ntawm 25 meters txog 150 meters txhais cov kev daws teeb meem ntawm daim duab; ib qhov tob ntawm 1 meter mus txog 40 meters txhais cov grey tus nqi ntawm cov ntawv sau.
Lub tshav kub hloov thiab kub sib tov ntawm lub yaj yuav tsum tau tsawg. Yog li ntawd, Daetwyler tau tsim cov khoom siv tshwj xeeb uas muaj cov khoom xa tawm nrog cov khoom ua rau cov organic uas tsis tshua muaj hluav taws xob dua li cov qauv zinc. Los ntawm ablating no zinc tshwj xeeb los ntawm vaporization, thaj tsam melting thiab burrs tuaj yeem raug txo kom muaj nyias txheej hauv cov nyiaj (2 mus rau 3 meters ntawm lub xov tooj ntawm tes).
Tag nrho cov dav hlau nruas yog siv tibsi los ntawm ib qho kev sib xyaw ua ke uas zoo sib xws. Thaum lub nruas khiav ncav 20 rpm, lub taub hau ntawm lub taub hau txav ntawm 15 mus txog 150 μm / pauv, tig mus rau lub nruas axis (nyob ntawm qhov kev daws teeb meem). Lub thickness ntawm mesh phab ntsa ntawm lub hlwb tsuas yog 4 mus rau 6 microns thaum lub suab tus nqi siab tshaj plaws. Qhov no yuav tsum yog lub hom phiaj ntawm lub nqaj yuav ua rau lub nruas qis rau li ntawm 1 micron.
Lwm txoj kev yog siv lub tshuab pulse-modulated high-power laser (nruab nrab zog ntawm 500 watts) nrog lub plhaub repetition zaus tes taws los piav ntau yam ntawm 30-100 kHz. Thaum twg lub zaus 35 kHz, muaj ntau zog rau ib lub plhaub zis, yog li ntawd ib qho kev txhaj tshuaj tuaj tau hnav ib lub xov tooj loj loj (xws li lub vijtsam nrog lub voj ntawm 140 microns thaum npo yog 70 kab / cm). Thaum twg tus zaus 100 kHz, lub zog ntawm ib lub plhaub zuj zus tuaj, thiab yog li ib lub xov tooj ntawm me yog muab sau (piv txwv li, ib qho screen uas muaj ib txoj kab ntawm 25 μm thaum qhov screen yog 400 kab / cm).
Lub lag luam ntawm laser nqaj yog tsis-tiv tauj, uas yog ib qho tseem ceeb kom zoo dua li electromechanical engraving siv ib lub pob zeb diamond. Ntev npaum li txheej txheem ntawm cov ntawv luam yuav tsum paub tseeb thiab rov qab ua tau dua, qhov ncaj ntawm qhov kev sib tw tuaj yeem lav tsis tau tag nrho ntawm lub nruas. Vim hais tias muaj kev sib thooj siab, qhov kev luaj nkaus xwb ib qhov laser yog li ntawm 10 lub sij hawm sai dua cov tshuab electrechanical.
Nqes siv paib waveform modulation
Muaj ntau ntau cov ntaub ntawv substrate (xws li daim ntawv los yog cov ntawv khoob nplais) ntawm lub luam ntawv luam, txhua tus nrog cov yam ntxwv ntawm cov khoom sib txawv. Kev hloov tus cwj pwm hloov ntawm cov cwj pwm yog nyob rau ntawm: lub npoo ntawm cov substrate (xws li roughness, number case absorption capacity), number case parameters (xws li cov viscosity lossis cov qauv ntawm cov pigment), luam ntawv plates. Rau txhua lub rooj sib txawv, ntau cov duab ntawm cov kabmob engraved siv tau los ua kom zoo.
Ntxiv nrog rau kev siv hluav taws xob thiab kev sib cog lus, lub hlwb yog cov sawv cev rau kev siv khawm khawm yawm suab ntawm laser nqaj. Yuav kom ua tiav ib hom duab rau txhua lub cell, lub stereoscopic intensity waveform ntawm lub nqaj yog cov khoom tsim muaj nyob rau ntawm lub sijhawm, thiab lub sijhawm tswj tau ntawm cov ntaub ntawv duab yog siab li 100 kHz. Tus txheej txheem ntawm txhua qhov ntawm cov qauv siv lub tshuab thev naus laus zis no yog tshwm sim hauv daim duab 4.
Cov duab, lub cheeb thiab qhov tob ntawm txhua tus xov tooj ntawm tes yuav txiav txim siab ntawm nws tus kheej los ntawm tus tes taws xob ua haujlwm ntawm kev siv lub zog thiab qhov ywj siab hloov ntawm lub zog ntawm txhua lub laser mem tes. Hom tshiab ntawm cov xov tooj hauv cov phaj ua cov txheej txheem hu ua Super Halfautotypical Cell (SHC), nws yog ib qho kev txuas ntxiv ntawm Halfautotypical cell (qhov tob thiab txoj kab uas siv ntawm lub xov tooj ntawm ib nrab ntawm cov xov tooj sib txawv, tab sis tsis yog tswj hwm).
SHC tes taws ua haujlwm pub rau lub laser system rau engrave ntau lub hlwb (tsoos, Autotypical, Halfautotypical). Hauv yav dhau los, nyias muaj nyias qhov sib txawv (electromechanical engraving, chemical etching). Tam sim no, cov kab tshiab ntawm tes yuav raug tsim los ua kom zoo dua ntais cov cwj pwm hloov thiab luam tawm rau txhua tus xim% -yog nqi thiab luam substrate.
Zoo thiab daim ntawv thov
Ntxiv rau qhov "single-shot single-hole" method of SHC beam waveform tes taws los piav, nws tseem ua tau los tsim cov kabmob engraved by superimposing laser pulses nrawm, tshwj tsis yog tias qhov chaw inch yog me dua qhov yuav tsum tau ntawm tes (xws li ib qho lub cheeb ntawm 10-15). Micron, qhov loj ntawm 100 microns). Cov duab thiab sab hauv ntawm cov hlwb tsim nyob ntawm seb puas muaj tus tes taw, sib tshooj, thiab kev soj tsuam ntawm cov laser pulses (xws li cov duab typesetting tshuab roj ntsha algorithms).
Nruam cov lasers nrawm los yog txho-ntsuas nplai kom tsim tau cov kab ua me me dhau ntawm daim npog lub pob zeb diamonds. Qhov kom zoo dua yog qhov kev daws teeb meem ntawm cov duab (piv txwv li, kev txiav txim siab ntawm 1000 tauj kav / cm nrog rau kev thauj me nyuam loj ntawm 10 microns thiab qhov chaw diameter ntawm 15-20 microns). Qhov tsis zoo yog qhov tsis muaj peev xwm ua tau, uas yuav tsum tau them rau kev siv lub sijhawm ua haujlwm ntau dua (li 1 MHz) thiab ib lub voj voog ntau lub voj voos.
High-brightness fiber ntau lasers (200-600 watts, nruam yoj, phom plawg) los yog ultrashort laub lasers pab no cov teebmeem siab heev vim tias lawv lub zog ncov siab thaum lub sijhawm tsom. Ntxiv nrog rau zinc, qhov no ci ntsa iab tuaj yeem siv los kos lwm yam ntaub ntawv xws li tooj liab thiab ceramics.
Cov duab layout tshuab scanning txheej txheem algorithm yog tsim rau ntau qhov siab txog kev siv 2D (luam ntawv) thiab 3D (luam ntawv). Piv txwv, kos ib daim ntawv cog lus ntawm RFID gravure.
Cov ntawv sau electronics yog ib qho tshiab technology tshiab, thiab cov lus tshaj tawm yuav tsum tau rau cov khoom hluav taws xob thiab cov circuits yuav tsim ib qho qauv tshiab rau kev sau zauv thiab kev ncaj ncees. Feem ntau ntawm cov organic los yog inorganic inks ntawm neeg tsim thiab semiconductors yog paste-zoo li, uas yog heev zog mus luam.
Rau cov tsoos tsho zoo nkauj, cov tsis muaj qhov ntxim nyiam ntawm cov phev, cov cuab yeej ntawm lub cell geometry thiab qhov ntxhib ntxhib ntxoo ntawm cov ntawv nplaum yog qhov tseem ceeb. Daim duab 5C qhia tau hais tias kev kos duab kos rau ntawm RFID tus kav hlau txais xov nrog ib thaj tsam ntawm 10 microns xwb.
