Kuyini ukwelashwa kwe-UV LED Spot? Konke odinga ukukwazi

Ukuhlolwa okujulile kobuchwepheshe be-UV LED

Kuyini ukwelashwa kwendawo ye-UV LED? Ekuphritheleni, i-elekthronikhi, ngisho nomkhakha wokukhiqiza amadivayisi wezokwelapha, ukuphulukisa izinamathiselo, ama-inks, nokugqoka kudinga inqubo yokukhiqiza esebenza kahle. Ukuthola ulwazi ngamasu okunemba kwe-UV LED Spot Curing nezinhlobonhlobo zayo kubaluleke kakhulu kunoma yiliphi ibhizinisi namuhla.

Kuyini i-UV LED Spot Curing? - Izimiso Eziyisisekelo Ukubuka

Izinto ze-photopolymer ezifana nezinamathiselo, ukumboza, nama-inks zinezicelo ezifinyelela kabanzi kunalokho abantu abaningi abakucabangayo. Ukuphulukiswa kwendawo ye-UV LED kubhekisela enqubweni ye- ukuphulukisa lezi zinto nge-UV light-emitting diode (LEDs) kusetshenziswa amasu wemephu yokukhanya. Ukusetshenziswa kwama-LED njengomthombo wokukhanya kunikeza ukusebenza kahle kwamandla kanye nemiphumela eluhlaza uma kuqhathaniswa namasu okuphulukisa i-mercury ne-arc lamp.

Iyiphi indlela esetshenziswa UV LED Spot Curing?

Ukuphulukiswa kwendawo ngama-LED e-UV kuyinhlanganisela ephumelelayo futhi ephumelelayo yobuchwepheshe obuningi obuhlobene ne-photopolymerization. Isibonelo, ukuqhekeka kusetshenziswe yi-boron ngamandla omshini noma ukukhishwa kwezinto ezibonakalayo noma izinto eziphilayo eziqukethwe ku-resin (noma i-polymeric) ngokuhlukanisa izibopho zamakhemikhali nokukhanyisa isibani se-UV. Ukubuyiselwa kwesitayela sokulungisa kwenziwa kumaphrinta we-prototyping nge-dummy yokuphulukisa i-dome yokuphulukisa eqoshiwe ngaphansi komhlaba, ngaphandle kwanoma iyiphi imaski ene-spot UV LEDs, futhi, ifiphaza ukuphulukiswa kwe-flexography.

Elements of a Photo-Curing Apparatus

Photopolymer ukunwetshwa isethi esebenzisa ukukhanya UV emitting diode kwesokudla roc ukukhanya LED. I-Flexographic Printer Plugins Ukuhlanganiswa kwe-photopolomer compact disc (CD) ukwelashwa usebenzisa ibhokisi le-UV set-top. Uhlelo ngalunye lwezithombe ezimile ze-photodiode lubhekisa ku-photodiode array eyakha isethi enamapuleti emi-2 emifanekiso: enye yazo esebenzayo, futhi incike kwezinye izithombe ezimbili ze-emitters' gap non-imaging optical interface disc.

• Ngenkathi ujova ama-cores, iveza izinto ezisebenzayo ze-photo-reactive ku-Compact Disc CRC (idiski ye-cores ekhulayo) ku-photoprotractivity, okuholela ekuboniseni okuqondisa ukuzwa okuhambayo kokukhipha idiski ukuguqula indawo ibe yi-core core main rotate disk.

• Linganisela uhlelo lwemishini ngokubuyiselwa kokucindezelwa okucacisiwe kwe-stave ye-flexure.

Primary Elements

• I-Wavelength: Abaqhubi abahleliwe be-diode abakhethekile bakhetha i-photoinitiator ehlukile ne-resin ene-LED eluhlaza okwesibhakabhaka ye-cobalt esebenzisa ama-diode / ama-LED e-Cob ku-365NM, 385NM, 395NM, no-405NM no-405NM ngama-wavelengths athile we-Cobalt aluhlaza okwesibhakabhaka asetshenzisiwe.

• Ukuqina kokukhanya kwe-UV: Ijubane nokujula kokwelapha kunqunywa ukuqina, okulinganiswa ku-mW / cm².

• Isikhathi: Ibhekisela kubude besikhathi lapho ukukhanya kwe-UV kuvuliwe.

• Umthamo: Ukuqina kuphindaphindwe ngenani lesikhathi lapho ukukhanya kuvezwa. Ukuze uvule ngokugcwele amandla okukhanya, umthamo ubalulekile.

• Iyunifomu: Ukuhlukahluka kwendawo yokuphulukisa ukukhanya kwe-UV phezu kokuchayeka okuningi.

• Ukuphathwa Kokushisa: Ngenkathi ama-LED engakhiqizi ukushisa njengamalambu wendabuko, asakhiqiza ukushisa futhi adinga ukupholisa ukuze afinyelele ekusebenzeni kahle.

• Ukusebenza kwe-Optical: Inani lokukhanya liyahlakazeka futhi ligxile ngelensi kanye nokufakwa.

Izinzuzo zokusebenzisa i-UV LED Spot Curing ngaphezu kwezinye izindlela

Ngokungafani nezindlela ezisebenzisa izibani ze-arc noma ze-mercury, inqubo iyashesha uma usebenzisa ama-LED e-UV.

• Ukusebenza kahle kwamandla okuvelele: Uma kuqhathaniswa nama-LED e-UV, ukusetshenziswa kwamandla kuphakeme kakhulu. 

• Ukuqina okuthuthukisiwe: Umholi wemboni emahoreni angama-20,000 wokusetshenziswa udlula izibani ze-mercury, ezinamahora ayi-1,000-2,000 kuphela. 

• Ayikho i-Warmup Time: Akukho ukufudumala kwedivayisi, okwandisa ukukhiqizwa ngokushesha.

• Ukushisa okuncishisiwe: Izinto ezimbozwe ngaphambilini kanye nama-substrates ngeke zilinyazwe ngokunyuka kokushisa, okwenza yonke inqubo iphephile kakhulu

• I-Eco-Friendly: Lo mkhiqizo unamathela ezinqubomgomo zemvelo lapho wenziwa. Ayikho i-mercury noma i-ozone esetshenziswayo.

• Ukulawulwa Kwenqubo Okuthuthukisiwe: Ukuqinisekisa ubude obufanele be-wave kanye nokuqina kuthuthukisa ukunemba nokukhiqiza kabusha.

• Izindleko zokusebenza ezincishisiwe: Ukugcinwa okuphezulu kuholela kumandla aphansi adingekayo ukuze kuqhutshwe izinhlelo, okwandisa ukonga.

Ububanzi be-UV LED Spot Curing Technology

Izindawo eziningi ziye zathuthukiswa ngenxa yemvelo ekhethekile kakhulu futhi enembile yokuphulukiswa kwendawo eholwa yi-UV.

Electronics Assembly 

Izinqubo zokukhiqiza ezisebenzayo, ezifana nomhlangano wesifunda oguquguqukayo futhi ophrintiwe, zihlanganise ubuchwepheshe bokuphulukisa indawo ye-UV LED yokubopha ukunamathela. Ukusetshenziswa kokunamathisela kwe-UV kuvumela ukuhlangana okusheshayo nokuphephile kwezingxenye ngaphandle kokulimaza izingxenye ezibucayi. 

Ukukhiqizwa Kwedivayisi Yezokwelapha

Imihlangano ye-catheter inezingxenye zokuthembeka okuqinile, inzalo, nezikhathi zokuphulukisa okusheshayo. Amadivayisi asebenzisa i-UV LED adinga isivinini esiphezulu sokuphulukisa ngesikhathi sokubopha i-catheter, umhlangano we-fiber optical, kanye nokuhlanganiswa kwezingxenye ezibucayi.

Ukuhlanganiswa Kwamadivayisi Optical

Ukuphulukisa ama-LED e-UV anikeza imingcele ehlanzekile kakhulu futhi ebushelelezi (engantengantengi), esiza ekuhlanganisweni kwamakhamera weselula namalensi wekhamera yedijithali.

Imboni yokunyathelisa

Ukuhlanganiswa kwama-LED e-UV ngobuchwepheshe bokuphrinta kwedijithali kunezela isivinini kanye nokuqina nekhwalithi ekuqedeni. Kuyazuzisa ikakhulukazi lapho uphulukisa ama-flexo inks, okwenza kube ngcono ukupakisha okuguquguqukayo, ukuphrinta okukhulu, i-inkjet yefomethi ebanzi, nokuphrinta ilebula.

Ngaphezu kwalokho, kwandisa ukuqedwa kokugqoka okuvikelayo kanye nokufakwa kwamadivayisi kagesi we-UV kanye nezingxenye eziphrintiwe ze-3D ukumelana nemithelela ephezulu namandla okuvikela, nokumelana ne-abrasion.

Ezinye izinhlelo zokusebenza

• Ukulungiswa okuzenzakalelayo nokuhlanganiswa kwezimoto
Izinketho zamasheya
• zemihlangano ye-elekthronikhi.
• Izinhlanganisela ze-3D ezigoqa ama-peripherals.

Ukukhetha uhlelo olufanele lokuphulukisa indawo ye-LED

Ngamunye we-photoinitiators ngokususelwa esifundeni se-implode repertoire: i-photoinitiator ye-adhesive noma i-epoxy kufanele ihambisane nobubanzi bokukhanya kwe-UV okusetshenzisiwe.

Imigomo mayelana nejubane lokuphulukiswa kwe-UV: ukunciphisa isikhathi sokusetshenziswa kokukhanya kwe-UV kufanele kuhlobene nokuqina kohlelo.

Ukuhlela ukuma kwe-contour: Ngenkathi ubheka indawo edinga ukumbozwa ngokufanayo, kubalulekile ukuqinisekisa ukuthi azikho izikhala ezisele.

Ukulawula ukukhishwa kokushisa kohlelo: kungakhathaliseki izimo ezizungezile, amadivaysi kufanele asebenze ngezinga elidingekayo.

Isici sefomu elihlangene neliphathwayo lihlobene namakhanda okuphulukisa ahlanganisiwe vs akhishwayo.

Ukuphendula Kwesistimu: Ukuzenzekelayo kungenzeka kuze kube sezingeni lokuthi isikhathi, amandla, noma ukuqina kokukhishwa kungalawulwa.

Ukucatshangelwa kwesabelomali: Ukusetshenziswa kwemali kwangaphambilini kuqhathaniswa nezindleko zokusebenza ezizokwenzeka kuwela ngaphakathi kwezindleko zesabelomali kanye / noma zokusebenza.

Isiphetho:

Ukubopha idivayisi yezokwelapha nokuphrinta ilebula ngezinye zezibonelo lapho ezinye izinhlelo zilwela ukuhambisana, kuyilapho ukwelashwa kwe-UV kungaqhathaniswa. Isikhundla sabo njengabaholi ezinhlelweni ezingabizi kakhulu sivela ekuhlanganiseni ijubane elimangalisayo, ukunemba, nokucatshangelwa kwemvelo. Ukuze uthole ubuchwepheshe be-UVET noma ezinye izinhlobo zemishini yokushisa ye-infrared, sivakashele kuwebhusayithi yethu. Uzophinde ufinyelele ezinhlobonhlobo zezibani zokuphulukisa indawo ze-UV LED, izilawuli, izinhlelo eziphelele zokuphulukisa, neminye imishini.
