Ukuvela Kwemishini Yokuphrinta Isikrini Esizenzakalelayo: Kusukela Kumathupha Kuya Kwemishini

Imboni yokuphrinta isikrini isihambe ibanga elide kusukela ezinsukwini zayo zokuqala zokusebenza ngezandla. Namuhla, imishini yokunyathelisa yesikrini esizenzakalelayo iye yashintsha indlela amaphrinti okwenziwa ngayo, yanikeza ukusebenza kahle okuthuthukile, ukunemba, nokuvumelana. Ngokuthuthuka kwezobuchwepheshe, le mishini iye yavela eminyakeni edlule ukuze ihlangabezane nezidingo ezikhulayo zemboni. Kulesi sihloko, sizobheka kabanzi ukuvela kwemishini yokuphrinta isikrini esizenzakalelayo, kusukela ekuqaleni kwayo okuthobekile kuya ezinhlelweni ezizenzakalelayo ezizenzakalelayo esizibona namuhla.

Umsuka Wokuphrinta Isikrini

Ukuphrinta isikrini, okwaziwa nangokuthi ukuhlolwa kukasilika, kubuyela emuva e-China yasendulo, lapho kwakusetshenziselwa ukuphrinta imiklamo yokuhlobisa ezindwangu. Nokho, kwaze kwaba sekuqaleni kwawo-1900 lapho le nqubo yathola khona ukuduma emazweni aseNtshonalanga. Ekuqaleni, ukuphrinta isikrini kwakuyinqubo eyenziwa ngesandla ehilela ukudala i-stencil esikrinini kanye nokucindezela ngesandla uyinki ezindaweni ezivulekile ungene ku-substrate oyifunayo.

Ukuphrinta isikrini okwenziwa ngesandla, nakuba kuphumelela, kwakuyinqubo enzima kakhulu eyayidinga izingcweti ezinekhono kanye namakhono alinganiselwe okukhiqiza. Ukuphrinta ngakunye kwakudingeka kwenziwe ngesandla, okuholela ezikhathini zokushintsha kancane kanye nemiphumela engaguquki. Njengoba imboni yokunyathelisa ngesikrini ikhula, kwaba nesidingo sekhambi elisebenza kahle futhi elizenzakalelayo.

Ukwethulwa Kwemishini Ezenzakalelayo

Maphakathi nekhulu lama-20, imishini yokunyathelisa isikrini se-semi-automatic yenza i-debut yayo. Le mishini ihlanganisa ukunemba kokunyathelisa okwenziwa ngesandla nezinye izici ezizenzakalelayo, ithuthukisa kakhulu ukukhiqiza nokusebenza kahle. Bafake ithebula le-rotary indexing elivumela izikrini eziningi ukuthi ziphrintwe ngesikhathi esisodwa, okunciphisa inani lomsebenzi odingekayo.

Imishini ye-semi-automatic iphinde yethula umqondo wokubhaliswa kwesikrini okwenziwa ngesandla, okuvumele ukunemba okukhulu nokuphindaphinda enqubweni yokuphrinta. Lokhu kwakusho ukuthi uma izikrini seziqondaniswe kahle, zizohlala zisendaweni efanayo ngesikhathi sokuphrinta, ziqinisekisa ukuphrinta okufanayo. Kodwa-ke, le mishini isadinga ukungenelela komuntu ekulayisheni nasekuthululeni ama-substrate kanye nokusetshenziswa kukayinki.

Ukukhuphuka Kwemishini Ezenzakalelayo Ngokugcwele

Njengoba isidingo sokuphrinta isikrini siqhubeka sikhula, abakhiqizi bafuna izindlela zokuqhubekisela phambili le nqubo ngokuzenzakalelayo. Lokhu kwaholela ekuthuthukisweni kwemishini yokunyathelisa isikrini ezenzakalelayo ngeminyaka yawo-1970. Le mishini ihlanganise izici ezithuthukisiwe ukuze kwenziwe lula inqubo yokunyathelisa futhi iqede isidingo sokungenelela komuntu.

Imishini ezenzakalelayo ngokuphelele ingaphatha yonke inqubo yokuphrinta kusukela ekuqaleni kuya ekugcineni, okuhlanganisa ukulayishwa kwe-substrate, ukubhaliswa, ukuphrinta, kanye nokukhipha. Basebenzisa isistimu yokuthutha ukuhambisa ama-substrates ngomshini, kuyilapho amakhanda okuphrinta amaningi esebenzisa uyinki kanye kanye. Lokhu kuvumela isivinini sokukhiqiza esisheshayo futhi kunciphisa kakhulu izindleko zabasebenzi.

Intuthuko Kwezobuchwepheshe

Eminyakeni yamuva nje, imishini yokunyathelisa isikrini esizenzakalelayo iye yathuthuka kakhulu kwezobuchwepheshe, yathuthukisa ukusebenza kwayo namandla ayo. Enye intuthuko enkulu kube ukuhlanganiswa kwezilawuli zekhompiyutha kanye nezinhlelo zokuthwebula izithombe zedijithali. Lokhu kuvumela amaphrinta ukuthi akhe ama-stencil edijithali anokulungiswa okuphezulu ngokubhaliswa okunembile, okuholela ekuphrinteni okubukhali nokunemininingwane eyengeziwe.

Ngaphezu kwalokho, intuthuko kubuchwepheshe be-robotics kanye ne-servo motor yenze imishini ezenzakalelayo yasebenza kahle futhi inembe kakhudlwana. Izingalo zamarobhothi manje sezisetshenziselwa imisebenzi efana nokulayisha nokukhipha i-substrate, ukuxuba uyinki, nokuhlanza isikrini. Lawa marobhothi angenza imisebenzi ephindaphindayo ngokunemba okukhulu, asuse iphutha lomuntu futhi aqinisekise imiphumela engaguquki.

Izinzuzo Zokuzenzakalela

Ukuvela kwemishini yokuphrinta isikrini okuzenzakalelayo kulethe izinzuzo eziningi embonini. Okokuqala nokubalulekile, i-automation ikhulise kakhulu isivinini sokukhiqiza. Obekungathatha amahora noma izinsuku ukunyathelisa ngezandla manje kungafezwa ngemizuzu nje embalwa. Lokhu akuthuthukisi ukusebenza kahle kuphela kodwa futhi kuvumela amaphrinta ukuthi athathe ama-oda amakhulu futhi ahlangabezane nezikhathi ezimisiwe eziqinile.

I-Automation iphinde yathuthukisa ikhwalithi nokuvumelana kwamaphrinti. Izilawuli zekhompuyutha nezinhlelo zezithombe zedijithali ziqinisekisa ukubhaliswa okunembile kanye nokunemba kombala, okuholela ezithombeni ezigqamile nezichazwe kahle. Ukwengeza, ukuqedwa kwephutha lomuntu kanye nekhono lokuphindaphinda izilungiselelo ukusuka emsebenzini kuye emsebenzini kuqinisekisa ukuphrinta okufanayo kukho konke ukwenziwa kokukhiqiza.

Ngaphezu kwalokho, i-automation iholele ekongeni kwezindleko ezinkulu zamabhizinisi okuphrinta isikrini. Ngokunciphisa inani lemisebenzi yezandla edingekayo, izinkampani zinganciphisa izindleko zabasebenzi futhi zabele kabusha izinsiza kwezinye izindawo zokusebenza kwazo. Ukukhula kokukhiqiza nokusebenza kahle kwemishini ezenzakalelayo kusho nokuthi amavolumu amakhulu angakhiqizwa ngesikhathi esifushane, okuholela emazingeni aphezulu enzuzo.

Sengiphetha, ukuvela kwemishini yokunyathelisa yesikrini esizenzakalelayo kuye kwayishintsha kakhulu imboni, kwayisusa emisebenzini yezandla edinga abasebenzi kakhulu yaya kumasistimu athuthukisiwe azenzakalelayo. Le mishini inikeza ukusebenza kahle okwengeziwe, ukunemba, ukungaguquguquki, nokonga izindleko. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, ikusasa lokuphrinta isikrini libukeka lithembisa, nemishini iba yinkimbinkimbi nakakhulu futhi inekhono. Njengoba isidingo samaphrinti enziwe ngendlela oyifisayo siqhubeka sikhula, imishini yokunyathelisa isikrini esizenzakalelayo izodlala indima ebalulekile ekuhlangabezaneni nalezi zidingo futhi iqhube imingcele yalokho okungenzeka emhlabeni wokunyathelisa.
