Kusindikiza pamwamba kumatsimikizira ngati chinthu cha RFID chikuwoneka ngati chaukadaulo kapena chotsika mtengo. Gulu la akatswiri limagwiritsa ntchito njira ziwiri zofananira pamalo a Jingzhou-kusindikiza pakompyuta kwa maoda ambiri komanso kusindikiza kwa digito kwa UV pa ntchito zosiyanasiyana za data. Njira iliyonse ili ndi ubwino wake wosiyana malinga ndi kukula kwa dongosolo, zojambulajambula, ndi gawo lapansi.
Kusindikiza pazenera kumakhalabe kofunikira kwa ma keyfobs a RFID ndi makhadi ofikira. Ukonde wa poliyesitala wotambasulidwa pa chimango cha aluminiyamu umanyamula chithunzi chojambulidwa. Kusankhidwa kwa ma mesh kumakhudza chilichonse chakumunsi. Coarser mesh imayika inki yambiri koma imataya tsatanetsatane. Zowonetsera 350-zogwiritsa ntchito logo yokhazikika zimayendera bwino pakati pa kusawoneka bwino ndi tanthauzo la m'mphepete. Zojambula zabwino kwambiri-zolemba zazing'ono zochepera 6pt kapena zotsogola-zimafunika ma mesh 400 kapena kupitilira apo, ngakhale kutumiza inki kumachepa ndipo liwiro la kusindikiza limatsika moyenerera.
Ngongole ya Squeegee ndi kukakamiza kumakhudza mwachindunji kusindikiza kwabwino. Ogwira ntchito zopanga adaphunzira kudzera m'mayesero kuti mbali ya 70-degree blade imagwira ntchito bwino pamalo a ABS keyfob, pomwe makhadi a PVC amachita bwino pa madigiri 65. Kutsetsereka kotsetsereka kumalepheretsa kusindikizidwa; osaya kwambiri amasefukira. Zosinthazi zidatenga miyezi kuti zisinthidwe kuti ziyimbidwe pagulu lililonse lazinthu.
UV{{0}ma inki ochirikizidwa m'malo mwa zosungunulira{1}kutengera zopangira zomwe zidapangidwa zaka zingapo zapitazo. Kusinthako kunathetsa zowumitsa zowumitsa ndikuchepetsa nthawi yosinthira kwambiri. Inki yonyowa ankafunika kuti achire kwa maola 24- isanafike sitepe yotsatira yopanga. Ma inki a UV amachiritsa pansi pa nyali mumasekondi. Liwiro la mizere lidakwera kuchoka pa zidutswa 800 pa ola kufika pa 2,000 pa ntchito zamtundu umodzi.
Malo ochiritsira amayendetsa nyali za LED UV pa 395nm wavelength. M'mbuyomu makina a mercury vapor adapanga kutentha kwambiri komwe kumapotoza makadi owonda a PVC. Ma LED amayenda mozizira kwambiri ndipo amakhala nthawi yayitali-mayunitsi apano akhala akugwira ntchito kwa zaka zitatu popanda kusintha nyali. Kutentha-zigawo zowoneka bwino ngati zilembo zoonda za PET zimatha kupotoza pansi pa nyale za mercury koma zimayendetsa kuchiritsa kwa LED popanda zovuta.
Kufananitsa mitundu kumatsatira dongosolo la Pantone. Makasitomala akamapereka zojambulajambula zokhala ndi maumboni a Pantone, chipinda cha inki chimasakaniza mitundu yamawanga kuti igwirizane. Chojambula cham'manja cha spectrophotometer chimatsimikizira kusakaniza kusanayambe kupanga. Kulekerera kwamtundu kovomerezeka kumakhala pa ΔE pansi pa 2.0 pantchito zambiri zamalonda. Kulekerera kwamphamvu kumawonjezera mtengo chifukwa kumafunikira zolemba zambiri zoyeserera ndikusintha.
Zambiri-kulembetsa mitundu pa ABS keyfobs kumabweretsa zovuta. Patatu-malo owoneka bwino amatanthawuza kuti madera osiyanasiyana amakhala pamtunda wosiyana malinga ndi skrini. Kulipiridwa kumabwera chifukwa cha kapangidwe kake koyenera komanso kusintha kwamphamvu kwa skrini. Zizindikiro zolembetsera zosindikizidwa pa chiphaso choyamba cha mtundu zimakhala ngati zilolezo za mitundu yotsatira. Ogwiritsa ntchito mwaluso amatha kupirira ±0.15mm pamitundu inayi-, ngakhale ±0.2mm imakhala yodziwika bwino pamaoda othamanga.
Maluso a digito
Kusindikiza kwa digito kwa UV kumagwira ntchito yomwe kusindikiza kwa skrini sikungathe kuchita mwachuma. Manambala a seri, ma QR, ndi zolemba zamunthu zimawonekera pazomalizidwa kudzera pamitu ya inkjet ya piezoelectric. Zida zimayika CMYK kuphatikiza inki yoyera molunjika pamtunda wapansi. Inki yoyera imakhala ngati maziko a inki zakuda pa-zamitundu yakuda{{4}popanda iyo, mitundu imawoneka yamatope komanso yochapitsidwa.
Kusindikiza kumafika pa 720 dpi pamakhadi athyathyathya. Malo okhotakhota a keyfob amavomereza kusasunthika kocheperako chifukwa mutu wosindikiza uyenera kukhala ndi mtunda wotalikirapo. Kukonzekera mafayilo ndikofunikira kwambiri. Zojambula zotumizidwa pa 72 dpi zimawoneka zovomerezeka pazenera koma zimasindikizidwa ndi pixelation yowoneka. Gulu lojambula zithunzi limatembenuza mafayilo amakasitomala kukhala 300 dpi osachepera asanapangidwe.
Kukonzekera Pamwamba
Kukonzekera pamwamba kumasiyana pakati pa zipangizo. Zigawo za ABS zimafunikira chithandizo cha corona kapena kugwiritsa ntchito koyambirira musanasindikizidwe. Corona imapangitsa kuti inki ikhale yolimba kwambiri-yomwe imapangitsa kuti inki ikhale yolimba komanso kusuluka pakatha masiku angapo. Makhadi a PVC amafunika kupukuta zosungunulira kuti achotse pulasitiki yotsalira yomwe imasunthira pamwamba posungira. Kudumpha sitepe iyi kumabweretsa kulephera kumamatira komwe kumawonekera masabata pambuyo pobereka, nthawi zambiri kumabweretsa madandaulo amakasitomala.
Kuyesa kwa Inki Adhesion
Kuyesa kumamatira kwa inki kumachitika zisanachitike zopanga zilizonse. Mayeso a cross-hatch test amakhalabe mchitidwe wokhazikika{2}}ma grid pattern yogoledwa kudzera mu inki layer, kutsatiridwa ndi tape pull-off. Zotsatira zovomerezeka zikuwonetsa zosakwana 5% kuchotsa inki. Zogulitsa zogwiritsidwa ntchito panja kapena malo ovuta zimayesedwanso kuphatikiza kukana kupukuta mowa komanso kuyerekezera kuwonekera kwa UV.
Malo Olamulidwa
Chipinda chosindikizira chimasunga kutentha ndi chinyezi. Kukhuthala kwa inki kumasintha ndi kutentha, kumakhudza kusamutsa ndi kusanja. Miyezi yachilimwe yokhala ndi chinyezi chambiri imayambitsa kuchiritsa kwa UV pang'onopang'ono chifukwa chinyezi chamumlengalenga chimasokoneza chemistry ya photoinitiator. Dongosolo lowongolera nyengo limapangitsa zinthu kukhala zokhazikika kotero kuti kusakanikirana kwa inki kumakhala kofanana.
Strategic Workflow
Kupanga ndandanda amawerengera mphamvu zosiyanasiyana za njira iliyonse yosindikiza. Oda pansi pa zidutswa 500 nthawi zambiri amapita ku digito ya UV chifukwa mtengo wokhazikitsira skrini sungathe kutsika pang'ono. Large imakhala ndi zidutswa 5,000 zomwe zimakonda kusindikiza pa skrini pamtengo wotsika-pa mtengo uliwonse ngakhale kuti mwakhazikitsa ndalama zambiri. Madongosolo omwe ali pakati amadalira zovuta za zojambulajambula ndi nthawi yomaliza.
Kuphatikiza komaliza
Ntchito yosindikiza imagwirizanitsa mwachindunji kumtunda kwa chip bonding ndi kuyang'ana kwapamwamba kwapamwamba. Ma tag amafika kuchokera pamzere womangirira wokhala ndi tchipisi ophatikizidwa ndi tinyanga za bala. Kusindikiza kumawonjezera mtundu wamakasitomala ndi data yosinthika. Zidutswa zomalizidwa zimapita kumalo oyesera komwe gawo lililonse limatsimikizira magwiridwe antchito a RF asanapake. Mchitidwe wotsatizana umatanthawuza kuti zovuta zosindikiza zimawonekera mwachangu-zosindikizira zolakwika kapena kulephera kumamatira kumagwira mkati mwa maola ochepa osati pambuyo potumizidwa.
