Isebenza kanjani ukuhlolwa kwe-UV LED? Izicelo nezinzuzo

How is Visual Inspection Conducted With UV LEDs?

Phakathi kwezinye izindlela zokuhlolwa okungabhubhisi (i-NDT), ukuhlolwa kwe-UV LED kumelana namaphutha angaphezulu ngoba, ngokungafani nezinye izindlela, akushintshi ukwakheka komzimba. Le ndlela isebenzisa ukukhanya kwe-ultraviolet ukwenza amaphutha abonakalayo avame ukungabonakali ngeso lenyama. Kulesi sihloko, sizoxoxa ngokusebenza kokuhlolwa kwe-UV LED, ukusetshenziswa kwayo emikhakheni ehlukene, kanye nezinzuzo zale ndlela uma kuqhathaniswa nezinye. 

Below Understanding the ECG Machine: Principle of Operation and Parts

Ukuhlolwa ngaphansi kokukhanya kwe-ultraviolet kusetshenziswa isimiso se-fluorescence. Uhlobo oluvame kakhulu kuleli kilasi, ngaphandle kokungabaza, i-UV LED, ekhipha ukukhanya ku-365 nm (UV-A band). Lezo zibani ziphendula ngodayi we-appliqué kanye nosawoti we-disodium we-fluorescein, osetshenziselwa ukwakhiwa kobuchwepheshe beseli lokugeleza. Amadayi akhipha imisebe ye-UV yama-wavelengths athile futhi izinkomba zomhlaba ezifana nama-laps kanye ne-porosity \ ukugqwala nakanjani kuzokhanyisa. Le ndlela yokuhlola ibonakala ngezici ezilandelayo:

• Izibani ze-UV LED: Lezi zenza umsebenzi obalulekile wokuhlinzeka ukukhanya kwe-ultraviolet ukwenza kusebenze izinqubo kudayi be-fluorescent.

• Ukusetshenziswa kwamadayi we-fluorescent: Lezi zisetshenziswa endaweni engenhla yezinto ezibonakalayo, okwenza ukutholwa kwamaphutha angaphezulu kube ngcono lapho kusetshenziswa umthombo wokukhanya one-UV.

• Amadokodo okuhlola: Imigodi ihlolwa ngokusebenzisa izibani eziphathwayo noma eminye imithombo yokukhanya emadokodweni okuhlola.

Iyini inqubo yokuhlolwa kwe-UV LED?

Isebenza kanjani ukuhlolwa kwe-UV LED? Ukuhlolwa okungabhubhisi (i-NDT) kusetshenziswa ukukhanya kwe-UV-A ngobude be-365nm kwezingxenye ezenziwe ngezingeziwe, amaphutha aveza ubuso azotholakala nge-fluorescence. Lapho into ingaphansi kwemisebe ye-ultraviolet, ithola i-fluorescence, ikhipha ingxenye yalawo mandla ngendlela yokukhanya, ebonakala ngeso lomuntu.

• Ukulandelana kuqala ngokusebenzisa i-tracer ye-fluorescent ebusweni bengxenye, bese, ngemuva kwesikhathi esithile, noma yimaphi amafutha ngokweqile adinga ukususwa. Ingxenye ifakwe esibani sokusebenza esifakwe i-UV LED. Ukutholwa kwamafutha afakwe ezikhaleni ezitholakalayo yilokho umcwaningi azokufuna. Ngaphansi kwezimo lapho umngcele wokungcola ugcinwa khona, udayi ongasakazeki uzoba yi-incandescent ngaphansi kokukhanya okumnyama, ngaleyo ndlela kuveze ukuqhekeka okungenzeka, ukuvuza, ama-pores, noma okunye ukushiyeka.
• Izibani ze-UV ze-LED zisetshenziselwa izinhlelo zokusebenza eziphambili zokukhanya okumnyama kwe-forensic, kanye nezimboni zezimoto kanye ne-aerospace zokuqhekeka, ukuvuza, ukushisela, nokuqinisekisa ukuhlanzeka ngenxa yezakhiwo zazo ezingezona eziyingozi, ukusebenza kahle, ukuqina, nokunemba okuphelele ekutholeni amaphutha.
• Ukuhlolwa kwekhwalithi nekhwalithi, hlola imboni ephezulu ye-UVNDT esebenza ngayo. Ngenxa yokunemba kwabo ngaphandle kokudinga ukulimaza into ehlolwayo, banikeza ukuhlolwa okuphelele.
• I-E-lettered Exon Ukuhlolwa kwe-LED kufaka phakathi ukusetshenziswa kwe-fluorescence, ezungeze umgogodla wedivayisi ezungeza. Ngaphansi kokuvuselelwa kukagesi okukhishwa ukusebenzisana kukagesi nezinto ze-fluorescent, ezimisiwe esimweni esisebenzayo, ngenkathi indawo ezungezile imnyama, zikhipha amandla abizwa ngokuthi 'ukukhanya' noma ukukhanya okubonakalayo, okuvumela ukutholwa kwamaphutha okungenziwa ngaphandle kokwephula ubuqotho bezinto ezibonakalayo, i-NDT.
• I-NDT ibalulekile uma kukhulunywa ngezimo nezimo lapho amandla nesakhiwo sezinto ezibonakalayo zibhekana nengcindezi enkulu. Ngoba ukuthembeka nokuphepha kuhlale kuyisidingo, ikhono lokusebenzisa i-UV ye-LED ukuthola amaphutha ngaphandle kokuyekethisa ukusebenza kwengxenye kuvumela lokhu.

Universal Applications to Other Industries

Ngenxa yendlela yokuthola ngokushesha yamaphutha ebusweni, ukuhlolwa kwe-UV LED kuyasiza ezindaweni eziningi, ezihlanganisa:

• I-Aerospace: Ukusebenzisa i-UV LED ukuhlolwa kwesakhiwo se-turbine blades kanye ne-fuselage sections_ ukuqinisekisa ukuthi lezi zingxenye ezibucayi azikho imifantu.

• Izimoto: Ukuhlolwa kokukhubazeka nokuqhekeka kwenziwa ezingxenyeni zenjini kanye nama-welds ukuphepha nokusebenza kwabo.

• I-Electronics: Ukuhlolwa kwamalunga e-solder namabhodi wesifunda we-micro fractures, okuholela ekuhlulekeni.

• Amadivaysi Wezokwelapha: Ukuqinisekiswa kwekhwalithi yamathuluzi okuhlinzwa namasirinji.

• I-Forensics: Ukutholwa koketshezi lomzimba namanye amamaki endaweni yobugebengu.

• Ukuphepha kokudla: Endaweni yokucubungula ukudla, njengokuhlolwa kokuhlola ukuhlanzeka nokungcola.

Izinzuzo ze-UV LED Inspection Technology

Ukuhlolwa kwe-UV kunezinzuzo eziningi uma kuqhathaniswa nezinye izindlela zokuhlola imikhiqizo ngenxa yentuthuko yezobuchwepheshe:

• Ukutholwa okuthuthukisiwe: Amaphutha angaphezulu angatholakala kalula ngokuhlushwa okuphezulu kokukhanya kwe-UV.

• Kwezomnotho: Izindleko zokukhiqiza nokugcinwa kwama-LED ziphansi njengoba zisebenzisa amandla amancane futhi zinesikhathi sokuphila isikhathi eside.

• Ukuguquguquka: Ukuhlolwa kungenziwa ezindaweni eziningi, kufaka phakathi ezikude, ngosizo lwamalambu e-UV LED aphathwayo.

• Impilo: Ngokungafani nobunye ubuchwepheshe, ama-LED e-UV aphephile ku-opharetha kanye nemvelo njengoba ekhipha ukushisa okuphansi futhi engaqukethe i-mercury.

• Ukuhambisana Ngokugcwele: Imiphumela enokwethenjelwa futhi engaguquguquki ingatholakala ngemihlahlandlela yomkhakha efana ne-ASTM E3022, lapho izibani ze-UV LED zingakhiwa khona ukuze zihambisane.

Ukucatshangelwa ekusetshenzisweni kokuhlolwa kwe-UV LED

Isebenza kanjani ukuhlolwa kwe-UV LED? Nazi izici ezibaluleke kakhulu okufanele zicatshangelwe ngesikhathi sokuhlela noma yikuphi ukuhlolwa kwe-UV LED ukuqinisekisa impumelelo: 

• Ukusethwa kwe-IFD Signaling Wavelength Selection: Isignali ye-IFD ingatholakala ku-FDDOP nge-polymer cishe ku-365nm. Lokhu kungenziwa ngokusebenzisa amaphaneli we-fluorescent Dyed Defect Obscuring. 

• Umthamo we-Emitted Irradiance: Ukukhanya okukhiphayo kufanele kube namandla ngokwanele ukufeza inhloso ehlosiwe, ngokuqondile noma ngokungaqondile.

• Ukwandisa ukungafani: Ukusetshenziswa kwezinto ze-UV kungasiza futhi ekwandiseni ukungafani kwesithombe esikhiqizwe nge-DONT imaging noma i-CRT imaging, kanye nokwenza isithombe sicace kakhudlwana.

• Ukuthuthukiswa kwemiphumela: Ngesikhathi sokuhlolwa, ukucima okuphelele kwanoma yikuphi ukukhanya kuzothuthukisa kakhulu amathuba okubona izinkomba ze-fluorescent.

Yini entsha nge-UV LED Inspection Technology?

Yini entsha ngezinhlelo zokuhlola ezisuselwa ku-UV LED? Nazi ezinye zezindawo ezithuthukiswa: 

• Ibhalansi Yokucubungula Okuzenzakalelayo: Ezindaweni eziphezulu zokuhamba, ukuthuthukiswa kuyaqhubeka ku-_Automated UVDAC_ noma i-Automated UV LED Data Capture.

• Imiphumela Yokuhlolwa Okusheshayo: Ama-algorithms e-AI ahlanganiswe ukucubungula idatha yesikhathi sangempela nokufinyelela okusheshayo emiphumeleni yempendulo esheshayo.

• I-Dosing ye-Operator: Lezi ziphathekayo futhi zihlangene; Kodwa-ke, izinhlelo ezintsha ze-compact zenza ukuthi kufinyeleleke izindawo ezinzima ukufinyelela.

Isiphetho

Ukuhlolwa okungabhubhisi, ukuhlolwa kwe-ultraviolet (UV) LED, ubuchwepheshe obusha. Njengazo zonke izindlela zokuhlola, zenziwa ebangeni elifanele nephephile ukusuka nasendaweni ehloliwe. Izinkomba zokuqhekeka komhlaba zihlolwa ngesikhathi senqubo, futhi imiphumela ihlaziywa ngaphakathi kokuskena. Izindawo eziningana eziqinile seziqalile ukusebenzisa le ndlela, ezibonisa ukubaluleka kwayo nokubaluleka ekuqinisekiseni kwekhwalithi yesimanje. Kunesizathu sokucabanga ukuthi i-UV LED izosiza kakhulu ekwenzeni inqubo yokuhlola iphephile, enokwethenjelwa futhi isebenze kakhudlwana emhlabeni jikelele. Vakashela UVET.
