Ezinyangeni ezimbalwa ezizayo, odokotela bamehlo bazogxila ezicini ezihlukene zokwenziwa kwamalensi kanye nokwelashwa kwendawo ukuze bathole ukuqonda okujulile kobunye ubuchwepheshe bakamuva nemishini ehilelekile.
Ukwenziwa kwelensi empeleni kuyinqubo yokubumba, ukupholisha kanye nokumboza imidiya ebonisa ngale ukuze igobe ukukhanya futhi iguqule ubude bayo bokugxila.Izinga ukukhanya okufanele kugotshwe ngalo linqunywa incwadi kadokotela elinganisiwe, futhi ilabhorethri isebenzisa imininingwane equkethwe encwadini kadokotela ukuze yakhe ilensi.
Wonke amalensi enziwe ngocezu lwempahla eyindilinga, ebizwa ngokuthi i-semi-finished blank.Lezi zenziwa ngamaqoqo ama-lens casters, mhlawumbe ikakhulukazi enziwe ngamalensi angaphambili aphelile, futhi ambalwa enziwe ngezinto ezingaqediwe.
Ngomsebenzi olula, onenani eliphansi, amalensi aqedwe kancane angase asikwe futhi ahlanganiswe ekusebenzeni [umumo uhambisana nohlaka], kodwa izinqubo eziningi zizosebenzisa amalabhorathri kadokotela ukuze zelashwe phezulu kanye nomsebenzi onenani eliphezulu oyinkimbinkimbi.Bambalwa odokotela bamehlo abangakwazi ukwenza ukwelashwa okungaphezulu kumalensi acishe aqedwe, kodwa empeleni, amalensi ombono owodwa aqediwe angasikwa abe umumo.
Ubuchwepheshe bushintshe zonke izici zelensi kanye nokukhiqizwa kwayo.Isisekelo se-lens siba lula, sibe mncane futhi sibe namandla, futhi ilensi ingaba nombala, ihlanganiswe futhi ihlukaniswe ukuze inikeze uchungechunge lwezakhiwo zomkhiqizo oqediwe.
Okubaluleke kakhulu, ubuchwepheshe bekhompiyutha buvumela ukwenziwa kwezikhala zamalensi zibe sezingeni elinembile, ngaleyo ndlela kudaleke nemiyalelo enembile edingwa iziguli futhi kulungiswe ukuphambuka kwe-oda eliphezulu.
Kungakhathaliseki ukuthi yiziphi izici zabo, ama-lens amaningi aqala ngamadiski enziwe ngezinto ezibonakalayo, ngokuvamile ama-60, 70, noma ama-80 mm ububanzi futhi angaba ngu-1 cm ubukhulu.Okungenalutho ekuqaleni kwelabhorethri kadokotela kunqunywa incwadi kadokotela okufanele icutshungulwe kanye nohlaka lwelensi okufanele lufakwe.Izingilazi zombono owodwa ezinenani eliphansi zingadinga kuphela ilensi eqediwe ekhethwe ohlwini lwezimpahla futhi isikwe esimweni sohlaka, nakuba nakulesi sigaba, ama-lens angu-30% adinga indawo eyenziwe ngokwezifiso.
Imisebenzi enzima kakhulu yenziwa kangcono ngodokotela bamehlo abanekhono nochwepheshe baselabhorethri ngokubambisana eduze ukuze kukhethwe imikhiqizo engcono kakhulu yeziguli, imiyalelo kanye namafreyimu.
Iningi labasebenzi liyazi ukuthi ubuchwepheshe bushintshe kanjani igumbi lokubonisana, kodwa ubuchwepheshe buye bashintsha indlela imiyalelo efika ngayo ekukhiqizeni.Amasistimu esimanje asebenzisa amasistimu e-electronic data interchange (EDI) ukuze athumele incwadi kadokotela yesiguli, ukukhetha amalensi, nokuma kohlaka elabhorethri.
Amasistimu amaningi e-EDI ahlola ukukhethwa kwamalensi kanye nemiphumela yokubukeka okungenzeka nangaphambi kokuba umsebenzi ufike elabhorethri.Ukuma kohlaka kuyalandelelwa futhi kudluliselwe ekamelweni lemithi, ngakho-ke ilensi ilingana kahle.Lokhu kuzokhiqiza imiphumela enembe kakhulu kunanoma iyiphi imodi yokulayisha kuqala ethembele kumafreyimu lebhu engase ibaphathe.
Ngemva kokungena elabhorethri, umsebenzi wezibuko ngokuvamile uzomakwa ngekhodi yebha, ifakwe ethreyini futhi ibekwe phambili.Azofakwa kuma-pallet anemibala ehlukene futhi ahanjiswe ngezinqola noma amasistimu amaningi okuthutha.Futhi umsebenzi wezimo eziphuthumayo ungahlukaniswa ngokwenani lomsebenzi okufanele wenziwe.
Umsebenzi ungase ube izibuko eziphelele, lapho ama-lens akhiqizwa khona, asikwe ekubunjweni kwefreyimu futhi afakwe kuhlaka.Ingxenye yenqubo ihlanganisa ukuphathwa kwendawo engenalutho, okushiya umjikelezo ongenalutho ukuze usikwe ube yisimo sohlaka kwezinye izindawo.Lapho uhlaka lulungiswa ngesikhathi sokuzivocavoca, okungenalutho kuzophathwa phezulu futhi imiphetho icutshungulwe ibe yisimo esifanele elabhorethri yokuprakthiza ukuze ifakwe ohlakeni.
Uma okungenalutho sekukhethiwe futhi umsebenzi unebhakhodi futhi ufakwe iphalethi, ilensi izobekwa mathupha noma ngokuzenzakalelayo kumaka welensi, lapho okumakwa khona indawo ephakathi nendawo yokubona.Bese umboza i-lens ngefilimu yepulasitiki noma itheyiphu ukuvikela indawo yangaphambili.I-lens ibe isivinjwa i-alloy lug, exhunywe ngaphambili kwelensi ukuze ibambe lapho ingemuva le-lens likhiqizwa.
Ilensi ibe isifakwa emshinini wokubumba, ololonge ingemuva lelensi ngokwencwadi kadokotela edingekayo.Ukuthuthukiswa kwakamuva kuhlanganisa isistimu yokuvimbela enamathisela isibambi se-plastic block endaweni eqoshiwe yelensi, ukugwema ukusetshenziswa kwezinto ezincibilikayo ze-alloy.
Eminyakeni yamuva nje, ukubunjwa noma isizukulwane sama-lens shapes senze izinguquko ezinkulu.Ubuchwepheshe bokulawula izinombolo zekhompiyutha (CNC) bususe ukukhiqizwa kwamalensi kusistimu ye-analog (kusetshenziswa umumo womugqa ukuze kwakhe ijika elidingekayo) kuya ohlelweni lwedijithali oludonsa amashumi ezinkulungwane zamaphoyinti azimele ebusweni belensi futhi lukhiqize umumo onembile. okudingekayo.Lokhu kukhiqizwa kwedijithali kubizwa nge-free-form generation.
Uma isimo esifiswayo sesifinyelelwe, ilensi kufanele ipholishwe.Lokhu bekukade kuyisiyaluyalu, inqubo edinga abasebenzi abaningi.Ukushelela kwemishini nokupholishwa kwenziwa ngomshini wokwenza insimbi noma i-disc yokugaya, futhi amamaki ahlukene amaphedi okugaya anamathiselwe emshinini wokwenza insimbi noma i-disc yokugaya.Ilensi izolungiswa, futhi indandatho yokugaya izohlikihla ebusweni bayo ukuze ipholishe endaweni ekhanyayo.
Lapho uthela amanzi nesisombululo se-alumina ku-lens, shintsha amaphedi namaringi ngesandla.Imishini yesimanje yenza ukuma kwelensi ngokunemba okuphezulu, futhi imishini eminingi isebenzisa amakhanda amathuluzi engeziwe ukuze bushelelezi indawo engaphezulu ukuze ifinyelele isiphetho esibushelelezi.
Khona-ke ijika elikhiqiziwe lizobhekwa futhi likalwe, futhi ilensi izomakwa.Amasistimu amadala avele aphawule ilensi, kodwa amasistimu esimanje ngokuvamile asebenzisa i-laser etching ukumaka kanye nolunye ulwazi olungaphezulu kwelensi.Uma i-lens izogcotshwa, ihlanzwa nge-ultrasonically.Uma ilungele ukusikwa ibe sesimweni sohlaka, inenkinobho egxilile ngemuva ukuze ifake inqubo yokuhlela.
Kulesi sigaba, ilensi ingase ibhekane nochungechunge lwezinqubo, okuhlanganisa ukuthayela noma ezinye izinhlobo zokumboza.Umbala kanye nokunamathela okuqinile kuvame ukusetshenziswa kusetshenziswa inqubo yokucwilisa.I-lens izohlanzwa kahle, futhi umbala noma inkomba yokugqoka izohambisana ne-lens kanye nezinto ezibonakalayo.
Izingubo zokulwa ne-anti-reflective, i-hydrophobic coatings, i-hydrophilic coatings kanye ne-antistatic coatings isetshenziswa ekamelweni eliphezulu le-vacuum ngenqubo yokubeka.I-lens ilayishwa kusithwali esibizwa ngokuthi i-dome bese ifakwa ku-vacuum chamber ephezulu.Impahla eyimpushana ifakwa ngaphansi kwegumbi, imuncwe emkhathini wegumbi ngaphansi kokushisisa kanye ne-vacuum ephezulu, futhi ifakwe endaweni yelensi ezingqimbeni eziningi zogqinsi lwe-nanometer kuphela.
Ngemuva kokuthi ama-lens eseqedile konke ukucubungula, azonamathisela izinkinobho zepulasitiki futhi afake inqubo yokuhlela.Ukuze uthole amafreyimu alula anozimele ogcwele, inqubo yokuhlela izosika umumo wekhonta welensi nanoma yimaphi ama-edge ukuze ilingane nohlaka.Ukwelashwa komphetho kungaba ama-bevel alula, ama-groove e-super-assembly noma imisele eyinkimbinkimbi yamafreyimu angaphakathi.
Imishini yesimanje yokugaya onqenqemeni iye yathuthukiswa ukuze ifake izindlela eziningi zefreyimu futhi ifake phakathi ukubhola okungenafreyimu, ukucisha kanye nokwenza kabusha emisebenzini yabo.Ezinye zezinhlelo zesimanjemanje azisadingi amabhlogo, kodwa kunalokho zisebenzisa i-vacuum ukuze ibambe ilensi endaweni.Inqubo ye-edging iphinde ihlanganise ngokuqhubekayo i-laser etching kanye nokuphrinta.
Uma ilensi isiqediwe, ingafakwa emvilophini enolwazi oluningiliziwe futhi ithunyelwe.Uma umsebenzi ufakwe ekamelweni likadokotela, i-lens izoqhubeka idlula endaweni yengilazi.Nakuba izinqubo eziningi zingasetshenziswa ukwenza amafreyimu acwebezelise, izinsiza zokucwebezelisa ngaphandle kwesayithi ziya ngokuya zisetshenziswa izinqubo zamalensi anenani eliphezulu, ama-in-line, ultra kanye nomsebenzi ongenafreyimu.Ingilazi yasendlini nayo inganikezwa njengengxenye yokuthengiselana kwengilazi yokupakisha.
Igumbi lemithi kadokotela linochwepheshe bezingilazi abanolwazi abangasebenzisa wonke amathuluzi namaphethini adingekayo, njenge-Trivex, i-polycarbonate noma izinto zenkomba eziphakeme.Baphinde baphathe umsebenzi omningi, ngakho-ke bahle ekudaleni imisebenzi ephelele usuku nosuku.
Ezinyangeni ezimbalwa ezizayo, Udokotela Wamehlo uzocwaninga ngokuningiliziwe ukusebenza ngakunye kwalokhu okungenhla, kanye namanye amasevisi atholakalayo kanye nemishini.
Siyabonga ngokuvakashela udokotela wamehlo.Ukuze ufunde okwengeziwe ngokuqukethwe kwethu, okuhlanganisa izindaba zakamuva, ukuhlaziya namamojula e-CET asebenzayo, qala ukubhalisa kwakho ngo-£59 nje.
Njengoba yonke idrama yobhubhane isadlalwa, akumangazi ukuthi kukhona izitayela ezithokozisayo ekwakhiweni kwezingubo zamehlo nokuthengisa ngo-2021…
