Raws li tus neeg sawv cev ntawm cov cuab yeej luam ntawv niaj hnub no, lub tshuab luam ntawv digital inkjet suav nrog ntau yam thev naus laus zis, suav nrog kev siv tshuab hluav taws xob zoo, kev ua cov duab digital, thiab microfluidic tswj, tsim ib qho kev tsim kho tshiab nyob rau ntawm "dynamic scanning + precision printing." Lub hauv paus ntsiab lus no tsis yog tsuas yog tawg los ntawm lub cev dav cov kev txwv ntawm kev luam ntawv ib txwm muaj, tab sis kuj muab cov khoom siv nrog kev ua haujlwm siab thiab kev ua haujlwm siab. kev cai.
Los ntawm tag nrho cov qauv kev xav, tus tsim ntawm lub scanning digital inkjet tshuab luam ntawv revolves nyob ib ncig ntawm "kab-los ntawm- kab duab." Cov cuab yeej muaj lub tshuab luam ntawv lub taub hau uas tau tsav los ntawm siab - cov lus qhia meej meej, cov tshuab luam ntawv lub taub hau rau kev txuas ntxiv lossis ntawm -xav tau inkjet luam ntawv, lub platform thauj khoom, thiab lub sijhawm tiag tiag - cov duab ua haujlwm thiab kev tswj cov lus tsa suab. Thaum lub sijhawm ua haujlwm, lub taub hau luam tawm txav ntawm qhov nrawm nrawm raws li qhov dav ntawm cov xov xwm thaum tau txais kab- los ntawm- kab lus qhia los ntawm cov duab ua haujlwm, tshem tawm cov kua dej rau hauv cov haujlwm sib xws raws li xav tau, yog li ua tiav cov qauv lossis cov ntawv hauv xov xwm. Txoj kev dynamic scanning no tso cai rau cov cuab yeej hloov kho rau cov xov xwm ntawm qhov sib txawv ntawm qhov ntev thiab qhov dav, tso nws los ntawm qhov dav txwv ntawm qhov ruaj khov -array luam ntawv.
Nyob rau theem luam ntawv mechanism, nws cov tub ntxhais nyob rau hauv synchronization ntawm droplet tswj thiab positioning. Piezoelectric los yog thermal npuas ntsiab nyob rau hauv lub printhead precisely deform raws li hluav taws xob teeb liab, tsim ink droplets nrog diameters ntawm kaum ntawm micrometers los yog txawm me me. Cov tee dej no ces coj mus rau qhov chaw substrate los ntawm ib qho hluav taws xob teb los yog airflow. Thaum lub sij hawm luam theej duab, lub zog tswj qhov system suav cov ntawv xov xwm ntawm qhov chaw luam ntawv thiab cov ntaub ntawv duab hauv lub sijhawm. Siv cov lus tawm tswv yim encoder thiab kaw- lub voj voog tswj algorithms, nws ua kom ntseeg tau tias qhov yuam kev ntawm qhov dej tsaws tsag nyob rau hauv qhov tsawg kawg nkaus, yog li ua tiav qhov kev daws teeb meem siab thiab kev sau npe raug siab. Qee cov khoom siv kuj suav nrog greyscale los yog hloov pauv hloov pauv tshuab, kho cov ntim ntim thiab ejection zaus los tsim cov duab nplua nuj thiab hloov pauv ntau yam.
Kev sib koom ua ke ntawm cov duab ua thiab kev tswj hwm yog lwm lub hauv paus ntsiab lus tseem ceeb. Cov tswv yim tsim cov ntaub ntawv, tom qab kev tswj xim, xim sib cais, thiab kev ua kom zoo, yog decomposed rau hauv cov ntaub ntawv kwj sib piv cov printhead scanning kauj ruam loj, tuav nruj lub sij hawm synchronization nrog cov neeg kho tshuab txav thaum lub sij hawm luam ntawv. Qhov no synchronization tsis yog tsuas yog nyob rau hauv siab - ceev kho vajtse kis raws, tab sis kuj nyob rau hauv software algorithms kom du acceleration thiab ceev hloov, tiv thaiv luam ntawv distortion los ntawm mechanical inertia. Nyob rau tib lub sijhawm, tus cwj mem muab qhov system dynamically kho qhov ntws thiab siab raws li lub taub hau luam ntawv kom ruaj khov ejection thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam ntawm number case thiab los ntshav.
Zuag qhia tag nrho, lub hauv paus ntsiab lus ntawm kev luam theej duab digital inkjet tshuab luam ntawv embodies qhov sib sib zog nqus kev sib koom ua ke ntawm ntau yam kev qhuab qhia: tswj tau scanning los ntawm precision mechanics, meej ejection los ntawm microfluidic technology, thiab zoo meej synchronization ntawm cov duab thiab cov lus tsa suab los ntawm digital tswj. Lub hauv paus ntsiab lus no tsis yog tsuas yog txhim kho kev luam ntawv zoo thiab ua tau zoo tab sis kuj tseem muab lub hauv paus txhim khu kev qha rau cov ntawv thov kev lag luam thoob plaws ntau cov ntaub ntawv thiab cov xwm txheej, txhawb kev lag luam luam ntawv mus rau qib siab dua ntawm digitalization thiab yooj.
