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 yearc eyomeleleyo eveliswe ngexesha le-welding ithathwa yisampula yokukhanya, ivuselela isekethe yolawulo, kunye nombane osebenzayo wesekethe yolawulo yongezwa kwivalve yolwelo lwekristale yokukhanya, kwaye ivalve yokukhanya yekristale yolwelo itshintsha ukusuka kwimeko esobala ukuya kwindawo evulekileyo phantsi kwesenzo sombane, kwaye ukuhanjiswa kwe-ultraviolet kuphantsi kakhulu. Inxalenye yokukhanya kwe-infrared ngevalve yolwelo yekristale yokukhanya ifunxwa sesinye isihluzo. Nje ukuba ukukhanya kwe-arc kucinywe, i-sensor yokukhanya ayisakhuphi umqondiso, 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.
