Kev sib raug zoo ntawm lub waveform ntawm uv tshuab luam ntawv nozzle thiab uv number case yog raws li nram no: cov waveforms sib xws rau cov inks sib txawv kuj txawv, uas feem ntau cuam tshuam los ntawm qhov sib txawv ntawm lub suab ceev ntawm tus number case, viscosity ntawm tus number case, thiab qhov ceev ntawm tus number case.Feem ntau ntawm cov tshuab luam ntawv tam sim no muaj cov qauv hloov pauv hloov pauv mus rau cov inks sib txawv.
Kev ua haujlwm ntawm cov ntaub ntawv nozzle waveform: cov ntaub ntawv waveform yog lub sijhawm ua cov nozzle piezoelectric ceramic ua haujlwm, feem ntau muaj qhov nce siab (them lub sijhawm nyem), lub sijhawm nyem tas li (squeeze duration), ntog ntug (sab tawm lub sijhawm), Lub sijhawm sib txawv uas tau muab yuav pom tseeb hloov cov cwj mem los ntawm lub nozzle.
1.Tsav Waveform Design Principles
Tsav waveform tsim cuam tshuam nrog kev siv lub hauv paus ntsiab lus ntawm peb lub nthwv dej.Amplitude, zaus thiab theem yuav cuam tshuam rau qhov kawg nkaus ntawm daim ntawv piezoelectric.Qhov loj ntawm qhov amplitude muaj qhov cuam tshuam rau qhov ceev ntawm tus number case droplet, uas yog ib qho yooj yim rau kev paub thiab hnov, tab sis lub zog ntawm lub zaus (wavelength) ntawm qhov ceev ntawm tus number case droplet tsis tas yuav tob heev.Feem ntau, qhov no yog qhov hloov pauv nrog qhov siab tshaj plaws (tus nqi zoo tshaj plaws) yog xaiv tau, yog li tus nqi zoo tshaj yuav tsum tau lees paub raws li tus cwj pwm sib txawv hauv kev siv tiag tiag.
2. Tus cwj pwm ntawm tus cwj mem suab nrawm ntawm waveform
Feem ntau sai dua tus number case hnyav.Qhov ceev ntawm lub suab ntawm dej-raws li number case yog ntau dua li cov roj-raws li number case.Rau tib lub taub hau luam ntawv, thaum siv ntau qhov sib txawv ntawm tus number case, qhov zoo tshaj plaws wavelength nyob rau hauv nws waveform yuav tsum tau kho.Piv txwv li, lub wavelength dav ntawm tsav cov dej raws li tus number case yuav tsum me dua li cov roj raws li tus number case.
3. Tus cwj pwm ntawm tus number case viscosity ntawm waveform
Thaum lub tshuab luam ntawv uv luam tawm hauv ntau lub ntsiab lus, tom qab thawj qhov kev tsav tsheb nthwv dej xaus, nws yuav tsum tau nres ib ntus thiab tom qab ntawd xa tus thib ob waveform, thiab thaum lub thib ob waveform pib nyob ntawm lub ntuj oscillation ntawm lub nozzle nto siab tom qab. thawj waveform xaus.Qhov kev hloov tsuas yog ploj mus rau xoom.(Kev sib txawv ntawm tus number case viscosity yuav cuam tshuam rau lub sijhawm lwj no, yog li nws tseem yog qhov tseem ceeb rau kev ruaj khov number case viscosity kom ruaj khov luam ntawv), thiab nws yog qhov zoo dua los txuas thaum lub sijhawm xoom, txwv tsis pub lub wavelength ntawm lub nthwv dej thib ob yuav raug hloov.Txhawm rau kom ntseeg tau tias cov inkjet ib txwm muaj, nws kuj ua rau qhov nyuaj ntawm kev kho qhov zoo tshaj plaws inkjet waveform.
4.Kev cuam tshuam ntawm tus number case ntom ntom ntawm waveform
Thaum tus number case ceev sib txawv, nws lub suab ceev kuj txawv.Nyob rau hauv cov xwm txheej uas qhov loj ntawm daim ntawv piezoelectric ntawm lub nozzle tau txiav txim siab, feem ntau tsuas yog cov mem tes dav ntev ntawm kev tsav tsheb waveform tuaj yeem hloov tau kom tau txais qhov zoo tshaj plaws pulse peak point.
Tam sim no, muaj qee lub nozzles nrog kev poob siab hauv kev lag luam UV tshuab luam ntawv.Thawj lub nozzle nrog qhov deb ntawm 8 hli yog hloov kho rau lub siab waveform kom luam tawm 2 cm.Txawm li cas los xij, ntawm ib sab tes, qhov no yuav txo qis kev luam ntawv ceev heev.Ntawm qhov tod tes, kev ua txhaum xws li ya tus number case thiab xim streaking kuj yuav tshwm sim ntau zaus, uas yuav tsum muaj qib siab dua ntawm uv tshuab luam ntawv manufacturers.
