Ya zuwa yanzu, na'urori masu auna firikwensin ultrasonic sun zama wani muhimmin bangare na rayuwar yau da kullun da samar da masana'antu.Daga gano matakin ruwa, ma'aunin nisa zuwa ganewar asibiti, filayen aikace-aikacen na'urori masu nisa na ultrasonic suna ci gaba da faɗaɗa.Wannan labarin zai ba ku zurfin fahimtar tsarin samar da na'urori masu nisa na kamfanin mu na ultrasonic.
1. Ka'idar ultrasonic jeri na firikwensin
Na'urori masu auna firikwensin Ultrasonic suna amfani da inverse piezoelectric tasirin piezoelectric yumbu don canza makamashin lantarki zuwa filaye na ultrasonic, sa'an nan kuma ƙididdige nisa ta hanyar auna lokacin yaduwa na katako na ultrasonic a cikin iska.Tunda an san saurin yaɗuwar raƙuman ruwa na ultrasonic, ana iya ƙididdige tazarar da ke tsakanin su biyu ta hanyar auna kawai lokacin yaɗuwar raƙuman sauti tsakanin firikwensin da abin da ake nufi.
2. Tsarin samar da na'urori masu auna firikwensin ultrasonic
Za mu nuna muku tsarin samar da firikwensin mu daga abubuwa masu zuwa:
❶Binciken abu mai shigowa -- Binciken kayan samfur, ana bincika ingancin kayan daidai da ka'idodin dubawa na duniya.Kayan da aka bincika gabaɗaya sun haɗa da kayan aikin lantarki (masu tsayayya, masu ƙarfi, micro-controllers, da sauransu), sassan tsarin (casings, wayoyi), da transducers.Bincika ko kayan da ke shigowa sun cancanta.
❷Facin da aka fitar daga waje ——- Ana fitar da kayan aikin lantarki da aka bincika don yin faci don samar da PCBA, wanda shine kayan aikin firikwensin.PCBA da aka dawo daga facin kuma za'a gudanar da bincike, musamman don duba bayyanar PCBA da ko kayan aikin lantarki kamar resistors, capacitors, da micro-controllers ana saida su ko kuma sun leka.
❸Shirin ƙonawa ——- Ana iya amfani da ƙwararrun PCBA don ƙona shirin don micro-controller, wanda shine software na firikwensin.
❹ Bayan walda —— Bayan shigar da shirin, za su iya zuwa layin samarwa don samarwa.Galibi na'ura mai sarrafa walda da wayoyi, da allunan walda tare da transducers da wayoyi masu ƙarewa tare.
❺ Semi-finished samfurin taro da gwaji -- na'urorin tare da welded transducers da wayoyi an harhada zuwa daya domin gwaji.Abubuwan gwajin sun haɗa da gwajin nesa da gwajin echo.
❻ Potting glue —— Modules da suka ci gwajin za su shiga mataki na gaba kuma su yi amfani da injin tukwane don yin tukunyar.Yafi don kayayyaki tare da ƙimar hana ruwa.
❼Gama gwajin samfur ——-Bayan potted module ya bushe (lokacin bushewa gabaɗaya 4 hours), ci gaba da ƙãre samfurin gwajin.Babban abin gwajin shine gwajin nisa.Idan gwajin ya yi nasara, za a yi wa samfurin lakabi kuma a duba yadda ya fito kafin a saka shi cikin ajiya.
