Kupyolera muzaka zambiri zogwira ntchito ndi opanga magetsi, nthawi zambiri timamva kuti opanga magetsi safuna kugula magetsi abwino a LED.M'malo mwake, iwo sadziwa kusiyanitsa anagulidwa magetsi LED, komanso nkhawa ngati iwo analipira mtengo wapamwamba kwa otsika khalidwe magetsi LED.Chifukwa chake, monga wopanga zowunikira, ndizovuta kuyankha pa kugula kwa magetsi a LED.Chifukwa mtundu wamagetsi osinthira ndizovuta kuyang'ana, wakhala wokalamba kwa maola 4 m'fakitale yake yopangira, ndipo ena amakhala ndi maola 24-72.Komabe, mankhwala okalambawa nthawi zambiri amakhala pafupifupi 5% kapena apamwamba mkati mwa miyezi 3-6 yobereka.Nthawi zambiri, mumikhalidwe yoyipa yotere, opanga zowunikira amavutika, amakhala makasitomala, ndikutaya makasitomala.
Nanga bwanji kutengera mtundu wa magetsi a LED?Titha kuzizindikira kuchokera m'mbali izi:
Choyamba:kukankhira processing chip-IC.
Zomwe zili pamagetsi oyendetsa galimoto ndi gawo lophatikizika, ndipo ubwino ndi zovuta za dera lophatikizidwa zingakhudze mwachindunji magetsi onse osinthika.Dalaivala Integrated mabwalo a mafakitale lalikulu mmatumba mu lalikulu ndi sing'anga-kakulidwe ma CD mafakitale;The dalaivala Integrated dera ukadaulo wa mafakitale ang'onoang'ono processing ndi kutengera nthawi yomweyo Kukwezeleza chiwembu kamangidwe ka mafakitale lalikulu, ndi kupeza ma CD ang'onoang'ono ndi sing'anga-kakulidwe ma CD mafakitale, amene sangathe nthawi zambiri kutsimikizira kugwirizana kwa batch Integrated mabwalo.ndi kudalirika, zomwe zimapangitsa kuti mphamvu yoyendetsa galimoto ikhale yosavomerezeka popanda chifukwa pakapita nthawi.Choncho, dera Integrated pa magetsi LED akukana opukutidwa, amene ndi yabwino kwa nyali Mlengi kumvetsa Integrated dera dongosolo ndi kuwerengera mtengo Kukwezeleza, kuti atsimikizire mtengo wogwira ntchito kusintha magetsi mankhwala.
Chachiwiri:Transformer.
Purosesa yogwiritsira ntchito imatha kuonedwa ngati chigawo chapakati chaubongo cha munthu yemwe amasintha magetsi, pomwe mphamvu yotulutsa ndi kukana kutentha kwambiri zimatsimikiziridwa ndi thiransifoma.Ma Transformers amatenga AC pano - mphamvu yamagetsi - mphamvu ya DC, ndipo mphamvu yochulukirapo ya kinetic imatha kudzaza makinawo.Zomwe zili mkati mwa transformer ndi pachimake ndi phukusi la waya.
Ubwino wa pachimake ndi chinsinsi cha thiransifoma, koma monga mbiya, sikophweka kuzindikira.Chizindikiritso chosavuta ndichakuti: mawonekedwe ake ndi owoneka bwino, wandiweyani komanso owala, ndipo mbali yakumbuyo imapukutidwa ndipo doko lotulutsa mpweya ndi chinthu chabwino.Pakadali pano, maginito omwe amagwiritsidwa ntchito ndi Shanghai Nuoyi ndi PC44 maginito pachimake, omwe amagwiritsidwa ntchito popanga nkhungu, omwe amaonetsetsa kuti magetsi azitha kugwira ntchito bwino.
Phukusi lawaya limapangidwa ndi ma wire core windings.The mankhwala khalidwe la mkuwa pachimake waya ndi mbali yofunika ya moyo utumiki wa anachita thiransifoma.Zingwe za aluminiyamu zovala zamkuwa zofanana ndi 1/4 mtengo wa mawaya ofiira amkuwa.Pazifukwa za mtengo ndi kupanikizika kwa ntchito, opanga ma thiransifoma nthawi zambiri amasakaniza zosinthira ndi zomangira za waya za aluminiyamu zamkuwa.Ndiye, kutentha kwa thiransifoma kukwera, kuwonongeka sikungatheke, kumapangitsa kuti magetsi asinthe komanso kuwala konseko kusakhale kothandiza.Zotsatira zake, zowunikira zambiri, makamaka zomwe zimakhala ndi magetsi osinthika, nthawi zambiri zimasinthasintha pakatha miyezi 6 yobereka.Kodi kusiyanitsa ngati mkuwa pachimake waya ndi wofiira mkuwa waya kapena mkuwa atavala zotayidwa?Gwiritsani ntchito chowunikira kuti muyatse ndikuwotcha aluminiyamu yamkuwa.Itha kuyezanso molondola kukana kwa koyilo ya solenoid.
Chachitatu:electrolytic capacitors ndi chip ceramic capacitors.
Ife tonse tikudziwa kuti ife tonse tikudziwa ubwino ndi moyo utumiki wa capacitors electrolytic, ndipo ife tonse timatenga izo mozama.Komabe, nthawi zambiri timanyalanyaza malamulo amtundu wazinthu zotumizira ma capacitor.M'malo mwake, moyo wa capacitor wotengedwa umawononga kwambiri moyo wamagetsi osinthira.Mafupipafupi ogwiritsira ntchito mphamvu yamagetsi pamapeto otsogolera amafika nthawi za 6,000 pamphindi, zomwe zimapangitsa kuti pakhale kuwonjezeka kwa kupulumuka kwa capacitor ndi kupanga mankhwala monga dothi.Pomaliza, batire ya lithiamu electrolyte imatenthetsa ndikuphulika.Timalimbikitsidwa kwambiri kutumiza ma electrolytic capacitors: sankhani njira yapadera ya electrolytic ya LED, ndipo mafotokozedwe amtundu wamba amayambira ku L. Panthawiyi, njira zathu zamagetsi zamagetsi zotumiza kunja zonse ndi ma electrolytic capacitors okhala ndi moyo wapamwamba wa Aihua.
Ceramic capacitors: Zipangizo zimagawidwa mu X7R, X5R ndi Y5V, ndipo mphamvu yeniyeni ya Y5V imatha kufika 1/10 yamtengo wapatali, ndipo mtengo wamtengo wapatali umangotanthauza 0 volts panthawi yogwira ntchito.Chifukwa chake, kukana kwakung'ono uku komanso kusasankhidwa bwino kumabweretsanso kusiyana kwamitengo, kuchepetsa kwambiri moyo wautumiki wamagetsi osinthira.
Chachinayi:dera mfundo ndi kuwotcherera njira kusintha magetsi magetsi.
Siyanitsani mtundu wa dongosolo la mapangidwe: Kuphatikiza pa luso laukadaulo, imathanso kuzindikirika molingana ndi njira zina zowonera, monga masanjidwe oyenera a zigawo, ukhondo, mlengalenga mwadongosolo, kuwotcherera kowala, komanso kutalika kowoneka bwino.Katswiri wabwino sakonda kupanga zosokoneza.Pakuti mawaya, handcrafting ndi zigawo zikuluzikulu zimasonyezanso lalikulu kusowa kwambiri luso luso.
Njira yowotcherera: kuwotcherera pamanja ndi njira yowotcherera pachimake.Monga ife tonse tikudziwa, nsonga kuwotcherera ndondomeko khalidwe la makina zochita zokha ayenera kukhala wapamwamba kuwotcherera pamanja.Njira yozindikiritsira: kaya kumbuyo kuli guluu wofiira (njira yothandizira solder phala + yowotcherera yamagetsi imathanso kumaliza kuwotcherera pachimake, koma mtengo wake ndi wokwera kwambiri).
Chida choyang'anira malo a SMD: AOI.Mu ulalo wa SMD, malowa amatha kuyang'ana momwe akugwetsera, kugulitsa zabodza, ndi magawo omwe akusowa.
Panthawiyi, chowunikiracho chidzagwedezeka pakapita nthawi, chomwe chimayamba chifukwa cha kutsekedwa kwa magetsi osinthika kapena mikanda ya nyali ya LED.Kuyang'ana kowonongeka kwa mankhwalawa sikophweka kupitilira kuyang'anira ukalamba, kotero ndikofunikira kugwiritsa ntchito AOI kuyang'ana chigamba cha magetsi osinthira.
Chachisanu:Yang'anani zotchingira zokalamba ndi zipinda zokalamba zotentha kwambiri zochulukirapo posinthira zinthu zamagetsi.
Ziribe kanthu momwe zopangira ndi kupanga zili bwino muzinthu zopangira ndi zida zamagetsi, kapena ukalamba uyenera kuyang'aniridwa.Ndizovuta kuyang'anira malipoti oyendera omwe akubwera azinthu zamagetsi ndi zosintha zamagetsi.Pokhapokha molingana ndi kukalamba kwa magetsi osinthika komanso kuwunika kwachitsanzo cha kutentha kwa chipinda chopitilira kutentha, komwe kudalirika kwamagetsi osinthira komanso ngati zida zopangira zili ndi zoopsa zachitetezo zitha kuyang'aniridwa.
Zotsatira za kuchuluka kwa kuyezetsa kopitilira muyeso kopitilira muyeso: Kulephera kwa kusintha kwamagetsi pamlingo uwu kuli pakati pa chikwi chimodzi mpaka 1 peresenti, ndipo kusachita bwino kumeneku kudzapezeka kokha pamene zikwi za ukalamba wosalekeza wotentha kwambiri.
Chipinda cha kutentha kosalekeza chimatha kutsanzira chilengedwe choyipa chomwe magetsi osinthira amagwirira ntchito.Kuyang'anira sampuli pansi pamiyezo yokhwima kumatha kuwulula kuchuluka kwamavuto monga ziwembu zosagwirizana ndi sayansi, zida zosakwanira, zoyika zounikira zosagwira ntchito, komanso mphamvu yamagetsi othamanga kwambiri.
Kukalamba kwanthawi yayitali kutentha kwachipinda: sankhani zolephera mwachisawawa monga kugwetsa, kutayikira kwa magawo, kukhudzika, ndi zina zambiri, zosefera kusagwira ntchito koyambirira kwa zigawozo, ndikuchepetsa kulephera kwa zomwe zidamalizidwa (1% mpaka 1/1000) .
Pa kutentha kwa chipinda, ukalamba umadya makina ambiri okalamba, zida ndi antchito.Tsiku lililonse, malo opangira 100,000 amayatsa ndikuzimitsa magetsi.Makina okalamba ndi zida zimakwirira malo osachepera 500 masikweya mita, okhala ndi malo okalamba opitilira 10,000, ndipo kukalamba kwa mzere wopanga kumalizidwa, zomwe ndizosowa pamsika.
