ROHM Smart Thermal Printhead STPH

ROHM's STPH (Smart Thermal Printhead) mndandanda wa printhead ndi chigawo chachikulu chozikidwa pa ukadaulo wosindikizira wamafuta, womwe umagwiritsidwa ntchito kwambiri posindikiza matikiti, kusindikiza zilembo, zida zamankhwala, zolembera zamafakitale ndi zina. Zotsatirazi ndi zoyambira zomveka kuchokera ku mbali ziwiri: mfundo zogwirira ntchito ndi ubwino waukadaulo:

1. Mfundo yogwira ntchito ya STPH printhead

Mndandanda wa ROHM STPH umagwiritsa ntchito ukadaulo wosindikiza wamafuta. Mfundo yake yayikulu ndikutulutsa zomwe zimachitika m'deralo pamapepala otenthetsera poyang'anira bwino zinthu zotenthetsera zazing'ono (zotentha) pamutu wosindikizira kuti apange zithunzi kapena zolemba. Njira yeniyeni ndi iyi:

Kuyika kwa data

The printhead imalandira chizindikiro (dijito ya digito) kuchokera ku dera lolamulira kuti mudziwe malo a pixel point yomwe imayenera kutenthedwa.

Kutsegula kwa chinthu chowotcha

Kutentha kwazitsulo pamutu wosindikizira (kawirikawiri wopangidwa ndi kutentha kwapamwamba kwambiri) kumatentha nthawi yomweyo pansi pa mphamvu yamagetsi (microsecond response), ndipo kutentha kumasamutsidwa pamwamba pa pepala lotentha.

Kukula kwa mtundu wa Thermosensitive reaction

Kupaka kwa pepala lotenthetserako kumagwira ntchito pa kutentha kwakukulu, ndipo malo opangira utoto amapanga ndondomeko yofunikira kapena malemba (palibe inki kapena riboni ya kaboni yofunikira).

Kusindikiza kwa mzere ndi mzere

Tsamba lonselo limasindikizidwa mzere ndi mzere kupyolera mu kayendetsedwe ka kayendetsedwe ka makina kapena kudyetsa mapepala.

2. Ubwino waukadaulo wa ROHM STPH printhead

Monga kampani yotsogola pantchito zama semiconductors ndi zida zamagetsi, ROHM's STPH mndandanda uli ndi maubwino otsatirawa pamapangidwe ndi magwiridwe antchito:

1. High kusamvana ndi kusindikiza khalidwe

Kutentha kwapamwamba kwambiri: Mndandanda wa STPH umagwiritsa ntchito teknoloji ya micro-machining, ndipo kachulukidwe ka zinthu zotentha amatha kufika 200-300 dpi (zitsanzo zina zimathandizira kumtunda), zomwe ndizoyenera kusindikiza malemba abwino, ma barcode kapena zojambula zovuta.

Kuwongolera kwa Grayscale: Sinthani bwino nthawi yotenthetsera ndi kutentha kudzera pa pulse wide modulation (PWM) kuti mukwaniritse kutulutsa kwamitundu ingapo ndikuwonjezera kusanjika kwa chithunzicho.

2. Kuyankha mwachangu komanso kukhazikika

Mapangidwe otsika kwambiri otenthetsera: Chotenthetsera chimagwiritsa ntchito zida zotsika zotentha, zotentha mwachangu / kuzizira, ndipo zimathandizira kusindikiza kosalekeza (monga osindikiza matikiti amatha kufika 200-300 mm/s).

Moyo wautali: Njira ya ROHM ya semiconductor imatsimikizira kuti chinthu chotenthetsera chimagwira ntchito, ndipo moyo wamba ukhoza kufika pamtunda wosindikiza wa makilomita oposa 50 (malingana ndi chitsanzo).

3. Kupulumutsa mphamvu ndi kasamalidwe ka kutentha

Mayendedwe oyendetsa bwino: IC yokhazikika yoyendetsa bwino, kuchepetsa kugwiritsa ntchito mphamvu (mitundu ina imathandizira kuyendetsa kwamagetsi otsika, monga 3.3V kapena 5V), kuchepetsa kuwononga mphamvu.

Tekinoloje yolipirira kutentha: imayang'anira yokha kutentha komwe kuli ndikusintha magawo otentha kuti apewe kusindikiza kosawoneka bwino kapena kuwonongeka kwa pepala chifukwa cha kutentha kwambiri.

4. Mapangidwe ang'onoang'ono komanso osakanikirana

Kapangidwe ka modular: mutu wosindikizira ndi dera loyendetsa galimoto zimaphatikizidwa kwambiri, kuchepetsa kuchuluka kwa zigawo zakunja ndikuchepetsa kapangidwe ka zida.

Maonekedwe owonda: oyenera kugwiritsa ntchito malo opanda malo (monga osindikiza kapena zida zamankhwala).

5. Kudalirika ndi kugwirizana

Kugwirizana kwakukulu: kumathandizira mitundu yosiyanasiyana yamapepala otentha (kuphatikiza mapepala amitundu iwiri) kuti akwaniritse zosowa zamafakitale osiyanasiyana.

Mapangidwe oletsa kusokoneza: dera lodzitchinjiriza la ESD kuti muteteze kuwonongeka kwa ma electrostatic ndikuwongolera bata m'mafakitale.

6. Kuteteza chilengedwe ndi kusamalira kochepa

Kupanga kopanda inki: kusindikiza kwamafuta sikufuna riboni ya kaboni kapena inki, kuchepetsa kusinthanitsa zinthu zogwiritsidwa ntchito komanso kuwononga chilengedwe.

Ntchito yodzitchinjiriza: mitundu ina imathandizira njira yotsuka yokha kuti ipewe zing'onozing'ono zamapepala kapena kuwunjikana fumbi.

III. Zochitika zofananira ndikugwiritsa ntchito

Kugulitsa ndi zakudya: Kusindikiza risiti pamakina a POS.

Logistics ndi kusungirako katundu: zilembo ndi kusindikiza kwa waybill.

Zida zamankhwala: ECG, lipoti la ultrasound.

Kuyika chizindikiro kwa mafakitale: tsiku lopanga, kusindikiza nambala ya batch.

IV. Chidule

Mitu yosindikizira ya ROHM STPH yakhala njira yabwino kwambiri yosindikizira mafuta chifukwa cha kulondola kwambiri, kuthamanga kwambiri, kugwiritsa ntchito mphamvu zochepa komanso moyo wautali. Ubwino wake waukulu waukadaulo wagona pakuphatikizana kozama kwa semiconductor process ndi kasamalidwe ka kutentha, komwe kumatha kukwaniritsa zosowa zosiyanasiyana kuchokera kwa ogula kupita kumakampani, ndikuchepetsa mtengo wokwanira wogwiritsa ntchito kwa ogwiritsa ntchito. Kwa opanga zida omwe amafunikira kusindikiza kodalirika komanso kothandiza, mndandanda wa STPH umapereka yankho labwino kwambiri
