Kyocera 4-inch 200 dpi Thermal PrintHead

M'magawo amasiku ano omwe akutukuka kwambiri osindikizira a digito ndi zizindikiritso zamafakitale, magwiridwe antchito a mutu wosindikizira ngati gawo lalikulu amatsimikizira kutulutsa bwino komanso kuthekera kopanga. Pazaka makumi ambiri zakuchulukana kwaukadaulo pazadothi zowoneka bwino, mitu yosindikizira ya 4-inch 200-dot yoyambitsidwa ndi Kyocera Corporation yaku Japan yatenga malo ofunikira pamsika wapadziko lonse lapansi wosindikizira mafakitale chifukwa chodalirika komanso kusinthika kwake.

1. Zaukadaulo: Luso la kuwongolera kugwetsa kwa inki kopangidwa ndi zoumba zolondola

Ubwino waukulu wa mutu wosindikiza wa Kyocera wa 4-inch 200-dot umachokera ku mapangidwe ake apadera komanso kugwiritsa ntchito sayansi ya zinthu. Poyerekeza ndi mitu wamba yosindikizira yachitsulo, Kyocera imagwiritsa ntchito njira yodzipangira yokhayokha ya silicon nitride ceramic flow flow yokhala ndi kukana kwa dzimbiri komanso kukhazikika kwamafuta.

Dongosolo lowongolera kutentha ndi njira ina yofunika kwambiri yaukadaulo. Mutu wosindikizira uli ndi makina otsekedwa opangidwa ndi sensor yotentha kwambiri komanso chotenthetsera cha semiconductor, chomwe chimatha kuyendetsa bwino kutentha kwa ntchito mkati mwa ± 0.5 ℃. Kuwongolera kutentha kumeneku kumatsimikizira kugwirizana kwa kukhuthala kwa inki pansi pazikhalidwe zosiyanasiyana zachilengedwe. Deta yeniyeni yoyezedwa ikuwonetsa kuti kutentha kozungulira kumasiyanasiyana pakati pa 15-35 ℃, kuthamanga kwa dontho la inki kumasinthasintha ndi zosaposa 2%.

2. Kusanthula kogwira ntchito: Kuganiza mokhazikika kwa mapangidwe, kusinthika ku zochitika zosiyanasiyana

The Kyocera 4-inchi 200-madontho kusindikiza mutu utenga kamangidwe modular, ndi mayunitsi ake akuluakulu zinchito akhoza mwachidule mu subsystems atatu: dongosolo galimoto kutengerapo utenga Kyocera wodzikuza KMS-200 dalaivala Chip, amathandiza 8-level grayscale kusintha, ndi deta njira00 MHz mlingo kufala kwa mtundu uliwonse 2; makina osindikizira a inki amaphatikizapo zipinda zazikulu ndi zowonjezera za inki ndi chipangizo chojambulira njira ziwiri, chomwe chingalepheretse mpweya wa pigment. Malinga ndi mayeso oyesa, pambuyo pa maola 500 akugwira ntchito mosalekeza, kutsekeka kwa nozzle kumakhala kosakwana 0,5%; makina okonzera amaphatikiza kupukuta komanso kuyeretsa koyipa, ndipo kuwongolera kumatha kupitilira katatu kuposa mitu yosindikiza wamba.

Mutu wosindikiza umathandizira mitundu yosiyanasiyana ya inki zamafakitale, kuphatikiza:

Inki yochokera m'madzi: yoyenera kusindikizira chakudya, mogwirizana ndi miyezo ya certification ya FDA

UV kuchiritsa inki: kuchiritsa liwiro mpaka 150 metres / mphindi, kuuma mpaka 3H

Inki yosungunulira: kukana nyengo yakunja kwazaka zopitilira 3 popanda kuzimiririka

Inki yocheperako: kusamutsa bwino kumafika 95%

Ndikoyenera kutchula makamaka kuti ili ndi mphamvu yosinthika kuzinthu zosiyanasiyana. Kupyolera mumsonkhano wa mbale wa nozzle wosinthika, nsanja yosindikizira yomweyi imatha kunyamula inki zosiyanasiyana ndi makulidwe osiyanasiyana a 1-20cP. Zoyesa zoyesa zikuwonetsa kuti posintha mitundu ya inki, zimangotenga mphindi 15 kuti musinthe, zomwe zimathandizira kwambiri kusinthasintha kwa mzere wopanga.

3. Ntchito yamakampani: gawo lofunikira lakuchita mwanzeru

Pankhani yosindikizira, Kyocera's 4-inch 200-dot printhead ikuwonetsa zabwino zake. Mzere wopangira chakumwa chapadziko lonse lapansi umagwiritsa ntchito printhead iyi kusindikiza manambala a batch tsiku, kukwaniritsa 100% kuzindikirika pa liwiro la mabotolo 600 / mphindi, ndipo cholakwikacho chimachepetsedwa kuchokera ku 0.8% mpaka 0.02% poyerekeza ndi zida zachikhalidwe za inkjet. Chifukwa cha kuthekera kwa kukonza kwa buffer komwe kumabwera ndi matrix a madontho 200, ntchito yake yolipirira yokha imatha kupangitsa kuti malo azikhala osasinthasintha pamene liwiro la conveyor likusintha ndi ± 10%.

Kupanga zamagetsi ndi njira ina yofunika yogwiritsira ntchito. Mu PCB board marking process, printhead imatha kupanga zilembo zomveka bwino pa 0.2 mm wandiweyani wa solder mask wosanjikiza ndipo imatha kusindikiza zilembo zazing'ono ngati 0.6 mm. Mayeso ofananiza akuwonetsa kuti pansi pamikhalidwe yomweyi, kutulutsa kwake kwa VOC kumakhala kotsika 30% kuposa zinthu zofanana.

Pamsika wosindikizira wa digito wa nsalu, osindikiza amtundu wa mafakitale okhala ndi bubu iyi amatha kusindikiza nthawi imodzi yamitundu 8, ndikupanga bwino mpaka masikweya mita 45 pa ola limodzi. Ukadaulo wapadera wa "inki drop positioning correction" utha kuwongolera zolakwika pakati pa ma ± 5 ma microns, kupangitsa kulondola kwapataniyo kufika pamlingo wotsogola wamakampani.

IV. Kukonzekera ndi kukonzanso: Kumanga dongosolo la utumiki wanthawi zonse

Kyocera yakhazikitsa dongosolo lathunthu lothandizira luso la 4-inch 200-point nozzle. Dongosolo lake laluntha lozindikira matenda limatha kujambula magawo opitilira 50 ndikuwongolera zolosera kudzera pa pulogalamu yodzipereka.

Kukonza tsiku ndi tsiku: kupukuta basi maola 8 aliwonse

Kukonza kwapakatikati: kuyeretsa koyipa koyipa sabata iliyonse

Zozama yokonza: akupanga mankhwala mwezi uliwonse

Poyerekeza ndi zinthu zofananira, ma nozzles a Kyocera amakhala ndi nthawi yayitali pakati pa zolephera (MTBF) mpaka maola 15,000.
