Qhov teeb meem ntawm QR code luam ntawv ntawm cov ntim luam yeeb tau raug daws; qhov zoo no -paub luam yeeb ntim lub tuam txhab tau nqis tes ua!
Hloov pauv QR cov lej sawv cev rau qhov txuas ntxiv thiab txhim kho QR code thev naus laus zis hauv kev ntim khoom. Los ntawm kev siv cov lej QR sib txawv rau kev ntim khoom, txhua chav me me ntawm cov khoom tuaj yeem muaj tus lej QR tshwj xeeb, ua kom paub tseeb tias "ib yam khoom, ib tus lej." "Ib Yam Ib Yam, Ib Txoj Cai" yuav tsis tsuas yog ntxiv dag zog rau kev tiv thaiv - cuav traceability rau cov khoom lag luam, tso cai rau kev taug qab mus rau txhua qhov tsawg tshaj plaws, tab sis tseem ua rau cov tuam txhab khaws cov ntaub ntawv los ntawm cov neeg siv mus rau tus kheej, ua kom muaj kev lag luam tus kheej rau cov khoom lag luam.
Nrog rau kev txhim kho cov thev naus laus zis tshiab thiab cov txheej txheem, daim ntawv thov ntawm QR cov lej ntawm cov ntim luam yeeb txuas ntxiv nthuav dav. Txhawm rau ua kom zoo dua qub thiab daws ntau yam teeb meem luam ntawv tsim nyog (xws li QR code kua nplaum, kab kab, kev sib txawv ntawm qib, thiab lwm yam), cov kws tshawb fawb hauv kev lag luam tau tshawb fawb thiab tshuaj xyuas, txhawm rau txhim kho cov khoom zoo thaum ua kom muaj kev ruaj ntseg ntawm QR code zoo. Kuv lub tuam txhab ua ntau yam -seem thiab kev sim ntsuas thiab tshawb nrhiav cov khoom siv luam ntawv tsis pub dhau lub sijhawm QR code luam ntawv, txhawm rau teeb tsa cov ntsiab lus tseem ceeb rau cov khoom siv tso tawm, kom ntseeg tau tias muaj txiaj ntsig, tsim qauv, thiab sib luag ntawm kev tswj hwm kev tsim khoom thiab kev sim los ntawm qhov chaw, txhim kho QR code luam ntawv zoo, muab cov neeg siv khoom nrog kev lag luam ntau dua thiab cov kev pabcuam zoo, thiab kev tshawb fawb zoo dua -
Cov khoom siv luam ntawv thiab cov qauv kev ua haujlwm
Cov khoom siv luam ntawv siv lub sijhawm no yog daim ntawv- pub lub tshuab luam ntawv inkjet, uas muaj cov cuab yeej siv tshuab (paper feeding mechanism, paper feed platform, paper rewinding mechanism), printing system, curing mechanism, and online inspection system; Cov tub ntxhais yog lub tshuab luam ntawv, uas muaj lub taub hau luam ntawv, CNC system, thiab number case mov system. Lub hauv paus tseem ceeb ntawm cov tshuab luam ntawv yog lub tshuab hluav taws xob tswj kev lag luam uas tswj cov khoom siv number case. Ua ntej, lub tshuab luam ntawv teeb tsa cov ntawv luam tawm, tom qab ntawd lub tshuab tswj hwm kev lag luam (lub rooj tswj hwm tseem ceeb) thiab cov txheej txheem digital -analog system lossis hloov cov ntaub ntawv, ncaj qha tswj lub taub hau luam ntawv.
Lub piezoelectric inkjet luam ntawv tshuab siv nyob rau hauv inkjet printers belongs rau chav kub thiab siab tshuab luam ntawv. Nws tso ntau yam me me piezoelectric ceramics ze ntawm lub taub hau lub taub hau. Vim hais tias cov piezoelectric ceramics muaj dabtsi yog khoov thiab deformation nyob rau hauv voltage hloov ntawm ob qho tag nrho, thaum cov duab cov ntaub ntawv voltage yog siv rau lub piezoelectric ceramics, expansion thiab vibration deformation ntawm ceramics hloov nrog cov duab cov ntaub ntawv voltage, xyuas kom meej tias tus number case nyob rau hauv lub luam lub taub hau yog ejected tusyees thiab yog nyob rau hauv ruaj khov tej yam kev mob ntawm ib txwm kub thiab siab.
Ink kub parameter test
Hauv qhov kev sim no, nrog lub tshuab luam ntawv ruaj khov, qhov ntsuas qhov sib txawv yog tus cwj mem kub, thaum lwm yam luam ntawv tsis hloov pauv. Cov kev hloov pauv hauv cov qauv luam tawm tau ntsuas ntawm lub substrate, thiab tus number case kub, droplet formation, flowability, thiab diffusion ntawm lub substrate raug soj ntsuam. Txhawm rau kom yooj yim dua sim thiab kwv yees qhov kev hloov pauv nyob rau hauv qhov sib txawv ntawm tus number case kub, thiab ib txhij sau square blocks los ntsuas lawv qhov sib txawv.
Raws li cov kev ntsuam xyuas saum toj no, nws tuaj yeem txiav txim siab tias kev hloov pauv ntawm tus lej ntsuas kub tuaj yeem cuam tshuam ncaj qha rau kev luam ntawv. Raws li pom nyob rau hauv daim duab 1, raws li tus number case kub nce, number case viscosity txo thiab ink fluidity txhim kho, cia zoo dua kis mus rau lub substrate nto, ua rau muaj tsawg defects (dawb me ntsis, hlua kab). Raws li pom nyob rau hauv daim duab 2, raws li tus number case kub nce, lub dot cheeb tsam los yog kab diffusion ntawm cov luam tawm qauv hloov me ntsis, tab sis lub chamfers thiab burrs ntawm cov npoo nce, visually ua rau cov cheeb tsam tshwm thicker.

Daim duab 2 Kev hloov pauv hauv cheeb tsam square ntawm qhov sib txawv ntawm tus number case kub
Voltage, tsheb ceev, thiab printhead qhov siab parameter xeem
Qhov kev sim no tau ua nrog lub taub hau luam ntawv ruaj khov, qhov twg qhov ntsuas qhov sib txawv yog qhov hluav taws xob, lub tsheb ceev, thiab qhov siab ntawm lub taub hau luam ntawv, thaum lwm yam luam ntawv tsis hloov pauv. Cov kev hloov pauv hauv cov qauv luam tawm ntawm lub substrate tau ntsuas. Los ntawm cov kev ntsuam xyuas no, nws tuaj yeem txiav txim siab tias qhov hluav taws xob cuam tshuam rau kev sib sau ua ke ntawm cov ntawv luam tawm thawj zaug, qhov sib txawv ntawm "satellite number case droplets," thiab deformation ntawm cov ntawv luam tawm thiab cov ntawv.
Nyob rau hauv lub tsheb ceev ntawm 120 m / min thiab tus number case kub ntawm 46 degree, kho qhov voltage coj mus rau kev luam ntawv hloov raws li qhia nyob rau hauv daim duab 3. Los ntawm daim duab, nws yuav pom tau hais tias voltage muaj me ntsis cuam tshuam rau cov printing duab. Txawm li cas los xij, raws li kev tsom xam, nyob rau hauv ib txwm muaj xwm txheej, tus number case tsim ib lub dav hlau ib txwm nyob hauv lub taub hau luam ntawv. Thaum siv hluav taws xob, tus number case pib ntws tawm mus rau sab nraud, tsim ib tus cwj mem ntev ntev. Nyob rau hauv qhov kev txiav txim ntawm nto nro, tus number case filament forms droplets. Los ntawm kev sib cuam tshuam ntawm cov tee dej thiab viscosity, cov filament tawg los tsim inkjet tsim. Yog hais tias lub filament ntev dhau lawm, satellite dots tau yooj yim tsim. Thaum qhov hluav taws xob siab, tus lej number case loj dua, qhov pib nrawm dua, thiab qhov nrawm nrawm dua, ua rau cov khoom me me. Brownian cov lus tsa suab ntawm cov khoom muaj zog dua, thiab cov ntaub ntawv tsim cov ntaub ntawv luv luv, ua rau nws yooj yim dua rau thawj tus cwj mem kom sib sau. Cov nyhuv luam ntawv zoo dua, thiab cov tuab kuj tseem yuav siab dua.
Daim duab 3 Voltage Variation Printing Effect
Nyob rau hauv ib qho hluav taws xob ntawm 32V thiab qhov kub ntawm 48 degree, lub tsheb sib txawv tau hloov kho kom kuaj cov number case poob coalescence ntawm qhov siab ntawm lub taub hau, raws li pom hauv daim duab 4; kev sib piv ntawm ya tus number case thaum coding nyob rau hauv lub tsheb sib txawv speeds, ib txwm printhead qhov siab, thiab printhead qhov siab txo los ntawm 3 hli, raws li qhia nyob rau hauv daim duab 5; QR code luam ntawv cuam tshuam nyob rau hauv lub tsheb sib txawv ceev thiab printhead siab yog qhia nyob rau hauv daim duab 6.
Daim duab 4 Droplet coalescence nyob rau hauv tib lub voltage, tib yam kub, tib lub nozzle qhov siab, thiab sib txawv tsheb speeds
Daim duab 5 Kev sib piv ntawm tus cwj mem txaws ntawm lub taub hau ntawm lub tsheb sib txawv, qhov siab ntawm lub taub hau ib txwm (h), thiab lub taub hau luam ntawv qhov siab qis dua 3 hli (h-3)
Daim duab 6 QR code luam ntawv cuam tshuam nyob rau hauv lub tsheb sib txawv ceev thiab txawv printhead heights
Los ntawm cov duab 4 txog 6, nws tuaj yeem pom tau tias ob lub tsheb ceev thiab lub taub hau siab siab cuam tshuam rau kev sib koom ua ke ntawm cov kua nplaum tseem ceeb, cuam tshuam ncaj qha rau cov tuab thiab deformation ntawm cov duab luam tawm, yog li cuam tshuam rau qib zoo thiab zoo li QR code luam ntawv. Qhov siab dua lub taub hau luam ntawv, qhov ntev ntawm tus number case threads, ua rau nws nyuaj rau lub ntsiab number case rau converge. Qhov loj dua lub tsheb ceev, qhov ntau dispersed cov number case droplets yog thaum lawv tsaws rau ntawm daim ntawv, ua rau cov tsis zoo. Raws li cov txheej txheem saum toj no, plaub qhov txheej txheem tseem ceeb tau sau tseg thiab txheeb xyuas: qhov kub thiab txias, lub taub hau hluav taws xob, qhov siab ntawm lub taub hau, thiab daim ntawv ceev, txhua yam cuam tshuam rau kev luam ntawv zoo. Tus cwj mem kub thiab qhov hluav taws xob txiav txim siab cov txiaj ntsig luam ntawv (dawb me ntsis, stringing), thaum lub tsheb ceev thiab qhov siab ntawm lub taub hau txiav txim siab tus number case droplet convergence thiab davhlau trajectory (txiav, thickness).
