Iauto mnyama ihelmet welding sisigcina-ntloko esizikhuselayo esenziwe ngemigaqo efana ne-optoelectronics, iimotor, kunye ne-photomagnetism.IJamani yaqala ukubhengeza i-DZN4647T.7 nge-elektroniki elawulwa nge-welded cover yefestile kunye nomgangatho weeglasi ngo-Oktobha 1982, kunye nomgangatho we-BS679 owabhengezwa yi-United Kingdom ngo-1989 uchaza ixesha apho i-shield yokukhanya itshintsha ukusuka kwimeko yokukhanya ukuya kwindawo emnyama ngexesha le-welding.I-China yaqala ukuphuhlisa i-photoelectric automatic color-tshintsha i-welding helmet yokukhusela ekuqaleni kweminyaka yoo-1990.
Okokuqala, isakhiwo siqulunqwe ngamacandelo amabini: umzimba oyintloko wesigcina-ntloko kunye nenkqubo yokutshintsha ukukhanya.Umzimba oyintloko wesigqoko uxhonywe entloko, kunye ne-flame retardant ABS injection molding, ilula, iqinile, inokulungelelaniswa kwiindawo ezintathu ezahlukeneyo, inokuziqhelanisa neentlobo zeemilo zentloko.Inkqubo yokukhanya ibandakanya inzwa yokukhanya, i-circuitry control, ivalve yokukhanya kwekristale yolwelo, kunye nesihluzo.
Okwesibini, umgaqo wokhuseleko, Imitha ye-arc eyomeleleyo eyenziwe ngexesha le-welding ithathwa yi-sensor yokukhanya, ibangela isekethe yokulawula, kunye ne-voltage esebenzayo yesekethe yolawulo yongezwa kwivalve yokukhanya yekristale yolwelo, kunye nevalve yokukhanya yekristale. utshintsho ukusuka kwimeko ecacileyo ukuya kwimeko ye-opaque phantsi kwesenzo sombane wombane, kwaye i-ultraviolet transmittance iphantsi kakhulu.Inxalenye yokukhanya kwe-infrared ngevalve yolwelo yekristale yokukhanya ifunxwa sesinye isihluzo.Nje ukuba ukukhanya kwe-arc kucinywe, i-sensor yokukhanya ayisakhuphi isignali, isiphaluka solawulo asisakhuphi i-voltage yokusebenza, kunye nevalve yokukhanya yekristale yolwelo ibuyela kwimeko ecacileyo.
Okwesithathu, iimfuno eziphambili zobugcisa :1. ubungakanani: ubungakanani bokuqwalasela obusebenzayo abuyi kuba ngaphantsi kwe-90mm×40mm.2.Ukusebenza kwefotogen: inombolo ye-shading, i-ultraviolet / infrared transmission ratio, parallelism kufuneka ihambelane nemimiselo ye-GB3690.1-83.3.Ukusebenza kwamandla: Ifestile yokujonga kufuneka ichaphazeleke kathathu ngaphandle komonakalo kwiqondo lokushisa kwegumbi kunye ne-45 grams yeebhola zetsimbi eziwa ngokukhululekile ukusuka ekuphakameni kwe-0.6m.4.Ixesha lokuphendula liya kuhambelana nemimiselo efanelekileyo.
Okwesine, izilumkiso zokusetyenziswa:1.I-auto darkening i-helmet ye-welding ifanelekile kuzo zonke iindawo zokusebenza ze-welding, kukho i-handheld kunye ne-head-mounted imveliso ezimbini.2.Xa iiglasi zibonakala zidanyaza okanye zibemnyama xa zikwimo eqaqambileyo, ibhetri kufuneka itshintshwe.3.Ukuthintela ukuwa okunzima kunye noxinzelelo olunzima, thintela izinto ezinzima ekukhuhleni iilensi kunye nesigqoko sokuzivikela.
