Ultrasonic hlau tsis xeb tau nrhiav los ntawm lub caij nyoog nyob rau xyoo 1930s. Thaum lub sijhawm, thaum qhov chaw tam sim no vuam electrode ntxiv rau kev ntsuas ultrasonic kev co, nws pom tau tias tam sim no tsis tuaj yeem txuas, thiab ultrasonic hlau txias vuam tshuab tau tsim. Txawm hais tias ultrasonic vuam raug tshawb pom ua ntej lawm, cov haujlwm ntawm kev coj ua tseem tsis tau pom tseeb txog tam sim no. Nws zoo sib xws rau kev sib txhuam vuam, tab sis nrog qhov sib txawv tias lub sij hawm ultrasonic vuam yog luv thiab qhov kub qis dua li ntawm recrystallization; nws tsis yog tib yam li lub siab vuam vim tias qhov ua ntawv thov lub zog zoo li qub ntau dua li lub zog vuam. Nws feem ntau ntseeg tias nyob rau theem pib ntawm cov txheej txheem ultrasonic vuam, cov oxide yog tangentially co tawm ntawm cov hlau, thiab tiv thaiv ntu ntawm qhov ntxhib saum npoo ua kom rov ua micro-vuam thiab rhuav tshem cov txheej txheem kom ua rau thaj chaw tiv tauj thiab ib txhij nce qhov kub ntawm thaj tsam soldering. Siab, yas deformation tshwm sim ntawm qhov interface ntawm qhov weldment. Nyob rau hauv txoj kev no, nyob rau hauv qhov kev txiav txim ntawm qhov sib chwv sib zog, cov leeg pob qij txha yog tsim thaum lawv mus rau ib leeg mus rau qhov kev deb ntawm kev sib txuas lus atomic. Lub vuam lub sijhawm ntev dhau lawm, lossis lub ultrasonic amplitude loj dhau, yog li ntawd lub vuam lub zog raug txo los yog tseem ua kom puas.Ultrasonic hlau vuam yog hloov ua kaum tawm phav phav tus ntawm cov xaim hluav taws xob tsuam hluav taws xob ib zaug ntxiv rau saum npoo ntawm ob lub hlau ua haujlwm tau txuas, thiab tom qab ntawd thov siv qee qhov siab kom ua rau cov hlau tsis sib txhuam thiab tsim fusion ntawm txheej txheej molecular, yog li kom ua tiav lub hom phiaj ntawm hlau hlau.
Dab tsi yog qhov sib txawv ntawm ultrasonic hlau vuam tshuab thiab ultrasonic yas vuam tshuab?
1.Ua ntej txhua yam, nws ua haujlwm nyob rau hauv kev sib txawv. Feem ntau, cov kev taw qhia kev co ntawm lub taub hau vuam hauv ultrasonic yas vuam yog txiav mus rau qhov chaw vuam, thiab kev co kev co ntawm lub taub hau vuam hauv ultrasonic hlau vuam yog mus tib seem rau txoj haujlwm vuam. Qee qhov tshwj xeeb, yas vuam kuj tseem siv tau hauv cov kab khiav ua ke, xws li nyias yas seem.
2. Qhov thib ob, raws li ultrasonic yoj raug siv los txuas cov hlau, qhov siab dua yuav tsum muab tso rau pem hauv ntej rau vuam siv tshuab ultrasonic; Piv nrog cov yas vuam yas, cov tseev kom muaj ntawm lub zog loj, lub zog ceev, kev ruaj khov thiab kev tswj tsis siv neeg tsis yog tib qib. Tam sim no, domestic ultrasonic yas vuam tshuab hluav taws xob ua hluav taws xob yog qhov yooj yim tus kheej Circuit Court, cov neeg sawv cev raug yog: 8400, 8700 daim ntawv qhia txog kev ua haujlwm txuas choj thiab Taiwan tshuab feem ntau siv ib nrab choj Circuit Court, nrog cov yam ntxwv zoo kawg nkaus ntawm kev sib hloov ua ke. Yog tias cov thev naus laus zis uas twb muaj lawm rau cov yas vuam tau ncaj qha mus rau cov hlau hlau, nws cov khoom siv dag zog yuav ua rau siv tsis ruaj khov ntawm cov khoom; Nws tau txais txiaj ntsig tsuas yog tus nqi qis, tab sis rau cov kev xav tau ntawm cov hlau hlau nws tus kheej, qhov kev ua tau zoo no yog daj ntau.
1. Muaj peev xwm loj zog, ruaj khov ultrasonic generator:
Thawj qhov yuav tsum tau ua ntawm lub tshuab hluav taws xob ruaj khov ultrasonic yog: tsis siv neeg ua qhov zaus. Tsis siv neeg tshaj tawm kev ceev ceev tuaj yeem xyuas kom lub kaw lus hloov pauv tuaj yeem ua haujlwm nyob rau hauv lub xeev resonant, piv txwv li ua kom lub taub hau vuam ntau kawg. Qhov yuav tsum tau ua ntawm kev siv lub tshuab hlau txuas yog txais yuav siv lub tshuab ua haujlwm tsis siv neeg ntau zaus thiab tsis tas yuav siv cov kev hloov pauv thaum hloov pwm pwm thiab kev ua haujlwm. Muaj cov teeb meem inductor phau ntawv hloov kho zaus ntawm cov khoom siv, qhov pib tuaj yeem ua tsis tau raws li qhov yuav tsum tau ua.
Lub tshuab hluav taws xob ruaj khov ultrasonic kuj tseem xav tau: kev ua kom muaj nuj nqis thiab qhov ntau ntawm cov tsis tuaj yeem hloov tau. Qhov kev hloov kho tsis tu ncua, uas tuaj yeem ua kom tau qhov sib xws ntawm vuam, yog qhov tseem ceeb ntawm kev tsim khoom ruaj khov; Stepless amplitude hloov kho yog qhov tseem ceeb rau lub hom phiaj ntawm cov khoom siv, xws li txuas cov ntawv ob leeg tooj liab thiab txhuas ntawv rau tib cov khoom siv los ntawm kev hloov kho parameter.
Lub zog loj muaj peev xwm: piv nrog cov vuam yas, cov hlau txuas yuav tsum muaj lub zog ua kom muaj zog, yog li nws yuav tsum muaj lub zog loj ntawm qhov muaj peev xwm. Piv txwv li, lub tshuab ntawm 20kHz yeej xav tau lub zog muaj peev xwm tshaj 3000W. Ntau lub tuam txhab ua rau cov lus tsis tseeb hais txog lub peev xwm fais fab, yog li peb tsuas yog xav los sib piv nws nrog cov yas welders uas lawv ua, vim tias tsis muaj leej twg ntseeg tias cov welders yas muaj ntawv sau ntau dhau.
2.High vuam taub hau: vuam hlau raws li kev siv kev lag luam, kev tiv thaiv kom tsis txhob muaj lub neej siab ntawm vuam taub hau.
3.Lub tshuab xa hluav taws xob zoo: piv txwv li, tus hloov khoom ntawm 20kHz yuav tsum muaj peev xwm tiv taus lub zog ntev lub sijhawm ntawm ntau dua 3kw. Ntau lub tuam txhab muaj cov hloov pauv, hloov pauv uas txuas rau cov yas zoo tib yam, uas nyuaj qhia los ntawm sab nraud, thiab tias' s tsis muaj cai sau.
4. Kev tswj hwm qhov ua tau zoo: nrog peb qhov kev tswj hwm qhov tseem ceeb ntawm vuam lub zog, lub sijhawm thiab qhov siab, ntau yam tswj hwm software tuaj yeem ua tau raws li qhov sib txawv.
