Screen luam ntawv yog cov txheej txheem luam ntawv nrov uas siv cov stencil thiab cov ntxaij vab tshaus los hloov cov number case mus rau ntau qhov chaw, xws li textiles, ntawv, iav, thiab lwm yam. Nws yog ntau yam thiab muaj txiaj ntsig zoo los tsim cov ntawv luam tawm zoo hauv ntau qhov ntau, ua rau nws nyiam ntawm cov lag luam, kws kos duab, tsim qauv, thiab cov neeg nyiam DIY.
Yuav kom ua tiav cov txiaj ntsig zoo tshaj plaws, nws yog ib qho tseem ceeb kom muaj cov cuab yeej zoo. Muaj ntau lub tshuab thiab cov cuab yeej siv hauv kev tshuaj ntsuam luam ntawv, txhua tus nrog nws lub hom phiaj thiab muaj peev xwm. Hauv tsab xov xwm no, peb yuav ua tib zoo saib qee lub tshuab siv ntau tshaj plaws siv hauv kev tshuaj ntsuam luam ntawv thiab lawv cov haujlwm.
1. Screen Printing Xovxwm
Lub tshuab luam ntawv luam ntawv, tseem hu ua lub tshuab luam ntawv tshuaj ntsuam, yog lub plawv ntawm txhua qhov kev tshuaj ntsuam luam ntawv. Nws yog ib qho khoom siv hnyav uas tuaj ntawm qhov sib txawv thiab kev teeb tsa, nyob ntawm qhov loj me, ntim, thiab qhov nyuaj ntawm kev tsim.
Lub vijtsam luam ntawv xovxwm suav nrog ntau yam tseem ceeb, suav nrog lub chaw luam ntawv, lub npov tuav, thiab lub squeegee. Lub chaw luam ntawv yog qhov chaw substrate (cov ntaub ntawv luam tawm ntawm) muab tso rau, thaum lub vijtsam tuav cov khoom ruaj ntseg mesh stencil nyob rau hauv qhov chaw. Lub squeegee txav hla lub mesh thiab nias tus number case los ntawm stencil mus rau lub substrate.
Muaj ob lub ntsiab ntawm kev tshuaj ntsuam luam ntawv xovxwm: phau ntawv thiab tsis siv neeg. Phau ntawv xovxwm cia siab rau tib neeg lub zog los ua haujlwm, txhais tau hais tias lub tshuab luam ntawv yuav tsum tau muab tes tso rau hauv substrate thiab rub lub squeegee hla lub mesh. Nyob rau hauv sib piv, tsis siv neeg presses yog tus kheej-powered thiab siv motors thiab pneumatics txav lub substrate thiab squeegee, ua rau cov txheej txheem luam ntawv sai thiab ntau npaum.
2. Qhov Chaw Tso Tawm
Lub tsev raug mob yog lub tshuab uas pab npaj cov ntxaij vab tshaus rau kev luam ntawv los ntawm kev nthuav tawm cov stencil mus rau lub mesh. Nws siv UV teeb los hlawv cov stencil rau hauv cov mesh, tsim kom muaj cov duab meej thiab ruaj khov uas tuaj yeem tiv taus ntau zaus luam ntawv.
Chav tsev raug muaj lub teeb ci, lub rooj nqus tsev, thiab lub vaj huam sib luag tswj. Lub tshuab luam ntawv tso qhov screen nrog stencil rau ntawm lub rooj nqus tsev, thiab chav tsev "sucks" lub vijtsam rau ntawm lub rooj. Lub teeb ci emits UV teeb rau ntawm stencil, uas ua rau cov emulsion hardens thiab tsim cov qauv tsim. Kev tswj vaj huam sib luag tso cai rau lub tshuab luam ntawv los kho lub sij hawm raug thiab siv, nyob ntawm seb qhov screen loj thiab qhov nyuaj ntawm qhov tsim.
3. Screen ziab khaub ncaws
Tom qab qhov screen tau nthuav tawm thiab tsim, nws yuav tsum tau qhuav ua ntej nws tuaj yeem siv rau kev luam ntawv. Qhov no yog qhov uas lub vijtsam ziab khaub ncaws tuaj yeem ua ke. Nws yog lub tshuab uas siv cua sov thiab cua ncig kom qhuav cov ntxaij vab tshaus sai thiab sib npaug, tiv thaiv cov emulsion los ntawm tev lossis tawg.
Lub npov tshuab ziab khaub ncaws nta chav ntsuas kub nrog ntau lub rhawv uas tuaj yeem tuav ob peb lub vijtsam ib zaug. Lub tshuab luam ntawv tso cov ntxaij vab tshaus tshiab tsim hauv lub txee thiab teeb tsa qhov kub thiab txias thiab lub sijhawm ntawm lub voj voog ziab. Cov cua kub ncig hauv lub chamber, tshem tawm cov dej noo ntawm cov ntxaij vab tshaus thiab tawm hauv lawv npaj rau kev luam ntawv.
4. Ink Mixing System
Kev tshuaj ntsuam luam ntawv yuav tsum muaj qhov sib xyaw ua ke ntawm cov xim number case kom ua tiav qhov xav tau xim thiab opacity. Yog li, tus number case mixing system yog lub tshuab tseem ceeb hauv txhua lub khw luam ntawv. Nws yog lub tshuab tswj hwm lub khoos phis tawj uas tso tawm thiab sib xyaw cov cwj mem raws li lub tshuab luam ntawv tshwj xeeb, txuag lub sijhawm thiab txo cov khoom pov tseg.
Lub tshuab ua kua number case muaj xws li lub computer, chav faib khoom, thiab xim database. Lub tshuab luam ntawv xaiv cov xim uas xav tau thiab nkag mus rau qhov xav tau ntawm lub computer. Lub dispensing unit pours tus nqi tsim nyog ntawm tus number case puag thiab pigment rau hauv ib lub thawv sib tov thiab nplawm qhov sib tov. Lub tshuab luam ntawv tuaj yeem kuaj cov xim ntawm cov qauv substrate kom txog rau thaum nws phim cov xim xav tau thiab sib xws.
5. Conveyor tshuab ziab khaub ncaws
Thaum lub substrate tau luam tawm, tus number case yuav tsum tau qhuav kom tsis txhob smudging los yog los ntshav. Lub tshuab ziab khaub ncaws yog lub tshuab uas siv cov cua sov thiab siv cov khoom siv txuas ntxiv kom qhuav cov number case sai thiab meej.
Lub tshuab ziab khaub ncaws muaj cov cua sov chamber nrog rau ntau yam cua sov, kev tswj qhov kub thiab txias, thiab siv conveyor siv. Cov luam ntawv substrate nkag mus rau hauv lub chamber thiab dhau los ntawm cov khoom cua sov, ziab cov number case. Kev tswj qhov kub thiab txias kom ntseeg tau tias cov cua sov zoo ib yam thiab kho tau, nyob ntawm seb hom substrate thiab xim number case. Txoj siv conveyor txav lub substrate los ntawm lub chamber yam tsis tau kov nws, tiv thaiv kev puas tsuaj los yog smearing.
