Ka ọ dị ugbu a, ihe mmetụta nke ultrasonic abụrụla akụkụ dị mkpa nke ndụ kwa ụbọchị na mmepụta ụlọ ọrụ mmepụta ihe. Site na nchọpụta ọkwa mmiri mmiri, nha anya na nyocha ahụike, mpaghara ngwa nke ihe mmetụta ultrasonic anya na-aga n'ihu na-abawanye. Isiokwu a ga-enye gị nghọta miri emi nke usoro mmepụta nke ụlọ ọrụ ultrasonic anya sensọ.
1. Ụkpụrụ nke ultrasonic nsonye ihe mmetụta
Ihe mmetụta dị iche iche nke ultrasonic na-eji mmetụta piezoelectric na-agbanwe agbanwe nke ceramics piezoelectric iji gbanwee ike eletrik n'ime oghere ultrasonic, wee gbakọọ ebe dị anya site na ịlele oge mgbasa nke ultrasonic beams na ikuku. Ebe ọ bụ na amaara ọsọ mgbasa nke ebili mmiri ultrasonic, enwere ike gbakọọ anya dị n'etiti abụọ ahụ site na ịlele oge mgbasa nke ebili mmiri dị n'etiti ihe mmetụta na ihe ebumnuche.
2. Usoro mmepụta nke ultrasonic nso sensọ
Anyị ga-egosi gị usoro mmepụta nke sensọ anyị site na isi ihe ndị a:
❶ Nyocha ihe na-abata -- nyocha ihe ngwaahịa, a na-enyocha ihe dị mma dị ka ụkpụrụ nyocha nke mba ụwa si dị. Ihe ndị a na-enyocha n'ozuzu gụnyere ihe elektrọn ( resistors, capacitors, micro-controllers, wdg), akụkụ nhazi (casings, wires), na transducers. Lelee ma ihe ndị na-abata etozuola.
❷Patching nke sitere na mpụga ——- A na-ewepụta akụrụngwa eletrọnịkị a nyochara maka patching iji mepụta PCBA, nke bụ ngwaike nke ihe mmetụta. PCBA lọta na patching ga-enyochakwa, tumadi iji lelee ọdịdị PCBA yana ma a na-eresị ma ọ bụ na-agbapụta ngwa elektrọnik dị ka resistors, capacitors na micro-controllers.
❸ Mmemme na-ere ọkụ ——- Enwere ike iji PCBA tozuru etozu ọkụ mmemme maka micro-controller, nke bụ ngwanrọ sensọ.
❹ Post-welding —— Mgbe emechara mmemme ahụ, ha nwere ike ịga n'ahịrị mmepụta maka mmepụta. tumadi welding transducers na wires, na ịgbado ọkụ sekit mbadamba na transducers na ọnụ wires ọnụ.
❺ Mgbakọ ngwaahịa na nnwale nke emechara ọkara -- modul nwere transducers na wires na-agbakọta n'otu maka nnwale. Ihe nnwale ndị a gụnyere nleba anya anya na ule nkwughachi.
❻ Gluo mmiri -- Modul gafechara ule ahụ ga-abanye n'ọzọ na-esote wee jiri igwe ite gluu mee ite. tumadi maka modul nwere ọkwa mmiri na-egbochi mmiri.
Nnwale ngwaahịa emechachara ——- Mgbe akpọchara modul potted (oge ihicha na-abụkarị awa 4), gaa n'ihu nyocha ngwaahịa emechara. Isi ihe nyocha bụ ule dị anya. Ọ bụrụ na ule ahụ ga-aga nke ọma, a ga-edeba ngwaahịa ahụ ma nyochaa ọdịdị ya tupu etinye ya na nchekwa.
