Inqubo yokuphulukisa indawo ye-UV LED: Isebenza kanjani nezicelo

Yini UV LED Spot Curing Work?

"Ukuphulukisa, ukukhiqiza nokuqeda" yimisebenzi emithathu okufanele yenzeke ezimbonini zobuchwepheshe zanamuhla ngokunemba okuphezulu nokunemba. Isikhathi esibekiwe esilahlekile akuyona inketho, futhi lokhu kuholele ekuthuthukiseni amasu okwelapha afana nokuphulukisa indawo ye-UV LED, ethembele ekuphulukiseni izinamathiselo, upende, nama-inks amandla kahle, futhi ngesivinini esisheshayo. Yini eyenza lobu buchwepheshe buthembise futhi buthole intshisekelo ezimbonini ezahlukahlukene? Yilokho kanye esizokumboza kulesi sihloko: isayensi, izinzuzo, izicelo, nekusasa.

How a UV does LED spot curing work?

Isebenza kanjani ukuphulukiswa kwendawo ye-UV LED? Ngaphansi kwesigaba se-UV LED spot curing kukhona inqubo yokuphulukisa ama-inks, ukumboza, kanye nokunamathisela ngemithombo yokukhanya ehambisanayo. Opharetha be-UV LED bafeza lokhu ngokubhekisa ama-lasers kumachashazi okunamathisela futhi bawashaqe ngama-lasers ane-wavelengths ethile (365nm, 385nm, noma 405nm). Ngokungafani nezindlela ezindala ezinezibani ze-mercury, lezi zinhlobo ezintsha zinenzuzo yazo njengoba zikhipha ukukhanya kuma-wavelengths aqondile. Ezinye izindlela ze-UVC "LED" zikhiqiza imiphumela ephakeme kunezinhlobo zangaphambilini ze-mercury-ezisekela isibani.

Izinguquko zamakhemikhali zihilela isinyathelo sokuphulukisa esincike ekukhanyeni kwe-UV. Lapho le misebe ithinta ubuso, yenza kusebenze izingxenye ezithile ezibizwa ngokuthi ama-photoinitiators ngaphakathi kwento ethile, futhi ukusabela okwaziwa ngokuthi i-polymerization kwenzeka. Ngenxa yokuhlelwa kabusha okukhulu, ukudlula kwesikhathi kuzoholela kuma-photoinitiators aguqule ukunamathela kwamanzi kube yisibopho esiqinile, esiqinile.
Ukunemba kwayo okuphezulu kuyenza ilungele izinqubo zenhlanzeko ezifana nokubopha idivayisi yezokwelapha, i-microelectronics, kanye nomhlangano we-optical.
Ukukhishwa okuphansi kokushisa, ukusetshenziswa kwamandla, kanye nokwanda kwesikhathi sokuphila kwezinhlelo zokuphulukisa indawo ze-UV LED kunenzuzo enkulu. Banikeza ukwelashwa okusheshayo kanye nokugcinwa okuphansi uma kuqhathaniswa nezibani zendabuko ze-UV. Ngaphezu kwalokho, zinobungani bemvelo ngoba aziqukethe i-mercury noma zikhiqize i-ozone.
Lobu buchwepheshe buthola isicelo kumadivayisi wezokwelapha acacile kakhulu lapho izitho zifakwa khona futhi zihlanganiswe ama-PCB, ngoba lezi zimboni zilwela ukuhambisana kwejubane nokuhambisana kwezinto ezibonakalayo. Izixazululo ezinokwethenjelwa futhi ezinembile ze-Ultra ziyadingeka ekukhiqizeni kwanamuhla, okuyilokho kanye uhlelo lwe-UV LED spot-curbing oluletha.

Izinzuzo ze-UV LED Spot Curing

1. Ukusebenza kahle kwamandla

Ukuqhathaniswa kwezinhlelo ze-UV LED nezibani ze-mercury vapor kuveza umehluko ophawulekayo ekusetshenzisweni kwamandla. Izindleko zamandla nezindleko zokusebenza kohlelo zincishisiwe ngenxa yokuguqulwa okuphumelelayo kwamandla kagesi ekukhanyeni kwe-UV kanye nezindleko zayo ezilandelayo. Ngaphezu kwalokho, ithuba lokuvula nokucima ama-UV LED ngokushesha liqeda isikhathi sokushisa esifunwa yizibani zendabuko futhi lithuthukise umkhiqizo.

2. Izinzuzo zemvelo

Ukungabi bikho kwezinto ezinobuthi ezifana ne-mercury noma ukukhiqizwa kwe-ozone ngesikhathi sokusetshenziswa kwama-UV LED kuthuthukisa kakhulu impilo nokuphepha emsebenzini ngokwenza ukungcola okuyingozi kuphelelwe yisikhathi. Izindlela ezikhethekile zokulahla azidingekile, ngaleyo ndlela kunciphisa izindleko.

3. Ukunemba nokulawula

UV LED spot ukuphulukisa amayunithi ukugxila ezithile amanani amangalisayo amandla ezindaweni ezithile ukuze izindawo ezithile, ngisho izifunda kunzima kakhulu ukufinyelela, kungenziwa ukwelashwa ngokufanayo. Le ndlela isebenza kahle kakhulu lapho kuqinisekiswa ukuthi ukuqedwa ezindaweni ezisezingeni eliphakeme kufinyelelwa ngenkathi kuncishiswa ukuchithwa kwe-4. Ukwandisa ivolumu nokunakekelwa kwempilo.

Izicelo ze-UV LED Spot Curing

1. Umhlangano wedivayisi yezokwelapha

Ama-LED e-Ultraviolet asetshenziswa njengezibopho zezingxenye kudivayisi yezokwelapha. Ngenxa yokushisa okuphansi okukhiqizwa ukukhishwa kwe-UV, ukunemba kwesibopho eceleni kokuvikelwa kwezingxenye ezibucayi kuqinisekisiwe.

2. Ukukhiqizwa kwe-Electronics

Ngokuya nge-optics, i-UV LED iqinisekisa ukubopha kwezingxenye noma imicu ye-optical nge-elekthronikhi. Lolu hlelo lokusebenza lufanelekile kakhulu kumadivayisi we-UV LED ngenxa yejubane lokuphulukisa okusheshayo nokushisa okuphansi okuhambisana nalo.

3. Imboni yezimoto

Ukubopha nokubekwa uphawu embonini yezimoto kusetshenziswa ukwelashwa kwe-UV LED. Lobu buchwepheshe buvumela ukudalwa kwezingxenye eziqinile, eziqondile zekhwalithi ephakeme, okusiza ukuthi kube indinganiso embonini.

4.3D Ukuphrinta

Ukuphulukiswa kwe-UV LED kuyinqubo eyisisekelo yokuphrinta kwe-SLA ne-DLP 3D. Ikhono lokwelapha i-resin, ungqimba ngongqimba, ngokunemba okunjalo okucacile, kuthuthukisa ubunzima nemininingwane etholakalayo ezintweni eziphrintiwe ze-3D eziqediwe.

Ukucatshangelwa Kwezokuphepha

Naphezu kokuncishiswa kwezingozi ezihambisana nalapho usebenzisa ama-UV LED ngaphezu kwamalambu e-UV, izinyathelo ezilandelayo kufanele zithathwe ukuphepha okuphezulu:

• Ukuvikelwa kwamehlo: Ukuvikelwa kwamehlo kuyadingeka njengoba ukubuka ngqo emisebeni kuyingozi. Abasebenzisi kufanele bagqoke izibuko zokuzivikela ezifanele.

• Ukuvikelwa kwesikhumba: Imisebe ilimaza izingqimba ezingenamkhawulo zesikhumba, futhi ukuchayeka isikhathi eside kungaholela ekushiseni okuyingozi. Izingubo ezifanele, njengama-overalls noma amagilavu, kufanele zibe futhi zinconywa lapho usebenzisa izinhlelo zokuphulukisa ze-UV LED.

• Ukupholisa umoya: Kunconywa ukugwema i-ozone noma ezinye izinto ezisele ezingadalwa ngesikhathi somjikelezo wokuphulukisa; ngakho-ke, isidingo somoya omusha endaweni yokusebenzela.

Ukukhethwa kwe-UV LED Spot Curing System efanele

Isebenza kanjani ukuphulukiswa kwendawo ye-UV LED? Imvamisa, imvelo, izinto zokwakha, nezinqubo zokufaka isicelo ziyizinkomba ezicacile zohlelo olufanele kakhulu lokuphulukisa i-UV LED. Ukuqonda ukusebenza kwenqubo yokuphulukisa indawo ye-UV LED kudinga ulwazi lwezingxenye eziyisisekelo kanye nokuxhumana kwazo nendawo yokuphulukisa. Ukubopha kwe-UV adhesive, umhlangano omncane wama-PCB, ukubopha kwe-catheter, ukulungiswa kwe-lens optical, ngisho namawashi amancane athuthukise izidingo ezikhethekile zokuphulukisa isixazululo. Ukuze uqale, hlola indawo kanye nemingcele yezinto ezibonakalayo zokucushwa kwesistimu:

• Imihlahlandlela yokukhanya kufanele ibe mncane futhi igxile ku-1 kuya ku-3 mm micro-bonding inserts (ama-catheter, izinzwa)

• Ngemisebenzi eyinhloko emhlanganweni wokunemba, amabala we-3 - 10 mm anele.

• Isevisi ephumelelayo kakhulu amaphuzu amaningi okuphulukisa ngamasistimu anemiphumela eminingi noma ukukhanya okuqhekekayo.

Okulandelayo, cabanga ngama-wavelengths we-LED. Ezinye izinhlobo zokukhanya zisebenza kangcono ezinhlotsheni ezithile zokunamathisela.

• Izingqimba zezicucu ezijiyile ze-opaque ziphulukiswa kangcono ngemisebe engu-365nm.

• Ukumbozwa okujwayelekile nokunamathisela kuphulukiswa kangcono ngemisebe ye-385nm / 395nm.

• Ama-resin acacile noma amancane aphulukiswa kangcono ngemisebe engu-405nm, njengoba evumela ukuphulukiswa okusheshayo.

Ngenkathi uhlola ukusebenza kwesibani se-UV, cabanga ngalokhu okulandelayo mayelana nokuqina kokuphulukiswa kwe-UV:

Ngezibopho ezibucayi, ukuqina okuphansi okungaba ngu-1000 mW / cm² kukhethwa.
Ngamandla aphezulu, ngaphezu kwe-2000 mW / cm², ukwelashwa kungenziwa ngokushesha ngamazinga aphezulu okudlulisa.

Isiphetho

Imihlahlandlela emfushane yokukhanya yamabanga aphakeme inikeza kangcono ukukhishwa okuqhubekayo kwe-UV kuwo wonke umhlahlandlela wokukhanya. Hlola ukulawulwa kokushisa kwesistimu yakho. Ukuze kube lula, khetha amayunithi ngokunwetshwa kwe-modular, izilawuli zesikhathi ezenziwe ngokwezifiso ze-PLC zezinqubo zeziteshi eziningi. Izinqubo zokuphepha zokuvimbela kufanele zibekwe phambili kuqala. Gxila ekuvikelweni kwe-UV, izici ze-ergonomic, izimpawu zokuvikela ze-CE njenge-RoHS, izitifiketi ze-ISO, futhi ikakhulukazi uma kungumklamo wezokwelapha ohlanzekile. Vakashela UVET ukuze uthole eminye imininingwane.
