Isikrini/Umugqa Wokuphrinta we-UV
Ukuphrinta kwendawo kunquma ukuthi umkhiqizo we-RFID ubukeka uchwepheshe noma ushibhile. Ithimba lezobuchwepheshe liqhuba izinqubo ezimbili ezifanayo endaweni ye-Jingzhou{1}}ukuphrinta kwesikrini okujwayelekile kwama-oda amaningi kanye nokuphrinta kwedijithali kwe-UV yemisebenzi yedatha ehlukahlukene. Indlela ngayinye inezinzuzo ezihlukile kuye ngosayizi wokuhleleka, ubunkimbinkimbi bomsebenzi wobuciko, nezinto ezingaphansi.
Ukuphrinta isikrini kuhlala kuyihhashi lokusebenza kuma-keyfob e-RFID namakhadi okufinyelela. I-polyester mesh enelulwe phezu kohlaka lwe-aluminium iphethe isithombe esifakwe i-stencil. Ukukhethwa kwemeshi kuthinta yonke into engezansi. I-coarser mesh ifaka uyinki owengeziwe kodwa ilahlekelwa imininingwane emihle. Izikrini ezingu-350-ze-mesh ezisetshenziselwa umsebenzi welogo evamile zishaya ibhalansi enengqondo phakathi kokufiphala nokuchazwa komphetho. Umsebenzi wobuciko ocolekile{8}}umbhalo omncane ongaphansi kuka-6pt noma amaphethini ayinkimbinkimbi-udinga i-400-mesh noma ngaphezulu, nakuba ukudluliselwa kukayinki kuncipha futhi isivinini sokuphrinta siyehla ngokufanele.
I-engeli ye-squeegee nokucindezela kuthinta ngokuqondile ikhwalithi yokuphrinta. Abasebenzi bokukhiqiza bafunde ngohlelo lokuhlola ukuthi i-engeli ye-blade engu-70-degree isebenza kahle endaweni ye-ABS keyfob, kuyilapho isitokwe samakhadi e-PVC senza kangcono kuma-degree angu-65. I-engeli ekhuphukela kakhulu ilambile ukuphrinta; angashoni kakhulu ayikhukhula. Lawa mapharamitha athathe izinyanga zokulungiswa ukuze ashayele isigaba somkhiqizo ngamunye.
U-UV{{0}oyinki abalawulekayo bathathela indawo ukwakheka kwe-solvent{1}}okusekelwe esitezi sokukhiqiza eminyakeni embalwa edlule. Iswishi isuse ama-racks okomisa futhi yanciphisa isikhathi sokushintsha kakhulu. Uyinki omanzi wawusetshenziswa ukudinga{10}ukwelashwa kwamahora angu-24 ngaphambi kwesinyathelo esilandelayo sokukhiqiza. Ama-ink e-UV aphulukisa ngaphansi kwesibani ngemizuzwana. Isivinini somugqa sikhuphuke sisuka ezingxenyeni ezingaba ngu-800 ngehora saya ngaphezu kwezi-2,000 emisebenzini yombala owodwa.
Isiteshi sokuphulukisa sisebenzisa amalambu e-LED UV ku-395nm wavelength. Ngaphambilini amasistimu womhwamuko we-mercury akhiqize ukushisa okudlulele okusonte amakhadi e-PVC azacile. Izinhlaka ze-LED zisebenza ngokupholile futhi zihlala isikhathi eside{3}}amayunithi amanje asebenze iminyaka emithathu ngaphandle kokushintshwa kwesibani. Ukushisa-ama-substrates azwelayo njengamalebula e-PET azacile angahlanekezela ngaphansi kwamalambu e-mercury kodwa aphathe ukwelapha kwe-LED ngaphandle kwezinkinga.
Ukufanisa imibala kulandela isistimu yePantone. Uma amakhasimende ehlinzeka ngomsebenzi wobuciko ngezithenjwa ze-Pantone, igumbi likayinki lixuba imibala yamabala ukuze ifane. I-spectrophotometer ephathwa ngesandla iqinisekisa ukuhlanganisa ngaphambi kokuthi ukukhiqizwa kuqale. Ukubekezelela umbala okwamukelekayo kuhlala ku-ΔE ngaphansi kuka-2.0 emisebenzini eminingi yezentengiso. Ukubekezelela okuqinile kwenyusa izindleko ngoba kudinga ukuphrinta okuningi kokuhlola nokulungiswa.
-Ukubhaliswa kwemibala eminingi kuma-keyfobs e-ABS kuletha izinselele eziqhubekayo. Ingaphezulu-enobukhulu obuthathu lisho izindawo ezihlukene ezihlala ezindaweni eziphakeme ezihlukene uma kuqhathaniswa nesikrini. Isinxephezelo siza ngedizayini yokulungisa ngokucophelela nokulungiswa kokuqina kwesikrini. Izimpawu zokubhalisa eziphrintwe kuphasi lokuqala lombala zisebenza njengemihlahlandlela yokuqondanisa imibala elandelayo. Ama-opharetha anekhono angabamba ±0.15mm ukubekezelela kuwo wonke-umsebenzi wemibala emine, nakuba ±0.2mm ijwayeleke kakhulu kuma-oda asheshayo.
Amakhono Edijithali
Ukuphrinta kwedijithali kwe-UV kusingatha umsebenzi ukuphrinta kwesikrini okungakwazi ukuwenza ngokonga. Izinombolo ze-serial, amakhodi e-QR, nombhalo womuntu siqu kuvela emikhiqizweni eqediwe ngamakhanda e-inkjet e-piezoelectric. Imishini ifaka i-CMYK kanye noyinki omhlophe ngqo endaweni engaphansi. Uyinki omhlophe usebenza njengesisekelo soyinki onemibala-emikhiqizweni enemibala{4}ngaphandle kwawo, imibala ibonakala inodaka futhi igezekile.
Ukulungiswa kokuphrinta kufinyelela ku-720 dpi ezindaweni zamakhadi ayisicaba. Indawo ye-keyfob egobile yamukela ukulungiswa okusebenzayo okuphansi ngoba isihloko sokuphrinta kufanele sigcine ibanga elikhulu lokuma. Ukulungiswa kwefayela kubaluleke kakhulu. Umsebenzi wobuciko othunyelwe ngo-72 dpi ubukeka wamukelekile esikrinini kodwa uphrinta ngephikselishini ebonakalayo. Ithimba lezithombe liguqula amafayela ekhasimende abe ubuncane be-300 dpi ngaphambi kokukhiqizwa.
Ukulungiswa kwendawo
Ukulungiswa kwendawo kuyahluka phakathi kwezinto. Izingxenye ze-ABS zidinga ukwelashwa kwe-corona noma isicelo sokuqala ngaphambi kokuphrinta. Iyunithi ye-corona iphakamisa amandla angaphezulu ngokwanele ukuze kunamathele uyinki{2}}i-ABS engalashwa ibangela ukuthi uyinki ube buhlalu futhi uxebuke phakathi nezinsuku. Amakhadi e-PVC adinga ukusulwa kwe-solvent ukuze asuse i-plasticizer eyinsalela ethuthela phezulu ngesikhathi sokugcina. Ukweqa lesi sinyathelo kubangela ukwehluleka ukunamathela okubonakala emavikini ngemva kokulethwa, ngokuvamile okudala izikhalazo zamakhasimende.
Ukuhlolwa kokunamathela kukayinki
Ukuhlolwa kokunamathela kukayinki kwenzeka ngaphambi kokuthi ukukhiqizwa kuqalise imikhumbi. Isivivinyo-se-hatch esiphambanayo sihlala siwumkhuba ojwayelekile{2}}kuyiphethini yegridi etholwa ngesendlalelo sikayinki, okulandelwa ukudonsa kwetheyiphu{3}}ukucisha. Imiphumela eyamukelekayo ibonisa ukususwa kukayinki okungaphansi kuka-5%. Imikhiqizo ehloselwe ukusetshenziswa ngaphandle noma izindawo ezinonya ithola ukuhlolwa okwengeziwe okuhlanganisa ukumelana nokusula utshwala kanye nokulingisa ukuchayeka kwe-UV.
Imvelo Elawulwayo
Igumbi lokuphrinta ligcina izinga lokushisa elilawulwayo kanye nomswakama. I-viscosity kayinki ishintsha ngokushisa, okuthinta ukudluliswa nokubeka izinga. Izinyanga zasehlobo ezinomswakama ophezulu zibangela ukwelapha kancane kwe-UV ngoba umswakama womkhathi uphazamisa ikhemistri ye-photoinitiator. Uhlelo lokulawula isimo sezulu lugcina izimo zizinzile ngokwanele ukuthi izilinganiso zokuxuba uyinki zihlala zingashintshile.
I-Strategic Workflow
I-akhawunti yeshejuli yokukhiqiza yamandla ahlukene wendlela ngayinye yokuphrinta. Ama-oda angaphansi kwezingcezu ezingu-500 ngokuvamile aya edijithali ye-UV ngoba izindleko zokusethwa kwesikrini azikwazi ukuncishiswa ngamanani amancane. Okukhulu kusebenzisa izingcezu ezingaphezu kuka-5,000 kuvumela ukuphrinta kwesikrini ngezindleko eziphansi{5}}zeyunithi ngayinye naphezu kokutshalwa kwezimali kokusetha okuphezulu. Ama-oda aphakathi ancike kubunkimbinkimbi bomsebenzi wobuciko kanye nengcindezi yomnqamulajuqu.
Ukuhlanganisa Okokugcina
Umsebenzi wokuphrinta uxhuma ngokuqondile ekubopheni kwe-chip phezulu nokuhlolwa kwekhwalithi engezansi. Omaka bafika besuka emugqeni wokubopha nama-chips ashumekiwe nezimpondo zenxeba. Ukuphrinta kwengeza umkhiqizo wekhasimende kanye nedatha eguquguqukayo. Izingcezu eziqediwe ziqhubekela eziteshini zokuhlola lapho yonke iyunithi ithola ukuqinisekiswa kokusebenza kwe-RF ngaphambi kokupakisha. Ukuhamba komsebenzi okulandelanayo kusho ukuthi izinkinga zokuphrinta zivele ngokushesha-amaphrinti angaqondani kahle noma ukwehluleka ukunamathela kubanjwe emahoreni ambalwa kunangemva kokuthunyelwa.
