Umgaqo kunye nomsebenzi weprobe ye-ultrasonic

1. Yintoni i-ultrasonic probe

I-probe esetyenziswe kuvavanyo lwe-ultrasonic yi-transducer esebenzisa i-piezoelectric effect yezinto eziphathekayo ukuqonda ukuguqulwa kwamandla ombane kunye nesandi samandla.Icandelo eliphambili kwi-probe yi-wafer, eyi-crystal eyodwa okanye i-polycrystalline sheet ene-piezoelectric effect.Umsebenzi kukuguqula amandla ombane kunye namandla omsindo omnye komnye.

2. Umgaqo we uphando lwe-ultrasonic

Iprobe exhotyiswe ngee-wafers ezimbini, enye njenge-transmitter kwaye enye njengomamkeli, ikwabizwa ngokuba yi-probe yokwahlula okanye iprobe edibeneyo edibeneyo.I-probe yezinto ezimbini iqulunqwe ikakhulu yisokethi, iqokobhe, umaleko oshiyekileyo, itshiphu yokudlulisa, itshiphu yokufumana, ibhloko yokulibaziseka, njl.Xa kuthelekiswa neprobes ezithe tye, iiprobe ezimbini zekristale ezithe tye zinobuchule obungcono bokubona iziphene ezikufutshane nomphezulu;iindawo zokubona ezirhabaxa okanye ezigobileyo, zinefuthe elingcono lokudibanisa.

Isetyenziswa kwiinkqubo zokufumanisa isiphene semi-automatic okanye ngokuzenzekelayo.Xa i-axis yesandi sesandi esikhutshwe yi-probe i-perpendicular kumphezulu wokubona, i-longitudinal wave isandi esithe ngqo sihlola i-workpiece;lungisa i-axis ye-beam yesandi ye-probe ukwenza i-angle ethile kunye nomphezulu wokufumanisa.Umqa wesandi unqanyulwe kujongano phakathi kwamanzi kunye nomsebenzi.Umqa wesandi ojijekileyo onqamlezileyo uyaveliswa kwindawo yokusebenza ukuskena icwecwe lomsebenzi.I-plexiglass okanye i-epoxy resin ephilisiweyo phambi kweprobe chip icutshungulwa kwi-arc ethile (i-spherical okanye i-cylindrical), kunye ne-point-focus okanye i-line-focused infocused water probe inokufumaneka.

3. Umsebenzi we-ultrasonic probe

I-1) Guqula amaza esandi abuyisiweyo abe ngamaza ombane;

2) Kukulawula ulwalathiso lokusasazwa kwe-ultrasonic wave kunye neqondo lokugxila kwamandla.Xa i-angle yesiganeko ye-probe itshintshiwe okanye i-angle yokusasazwa kwe-wave ye-ultrasonic itshintshiwe, amandla aphambili e-wave wave anokuthi afakwe phakathi kwii-engile ezahlukeneyo okanye ukuqondisa kwezandi zesandi kunokutshintshwa ukuphucula isisombululo. .Ireyithi;

3) Ukufezekisa ukuguqulwa kwamaza;

4) Kukulawula i-frequency yokusebenza, efanelekileyo kwiimeko ezahlukeneyo zokusebenza.
