Dab tsi yog cov khoom tseem ceeb ntawm kev siv tshuab ultrasonic welding? Lub tshuab nqus hlau ua hluav taws xob li cas?
Cov khoom tseem ceeb ntawm cov tshuab ultrasonic welding yog lub tshuab hluav taws xob, lub tshuab hloov pauv hloov, hloov kho cov qauv (qee zaus hu ua cov nplaim hluav taws xob) thiab lub taub hau vuam. Lub tshuab hluav taws xob hloov lub zog siv hluav taws xob nrog lub zog ntawm 50-60Hz thiab qhov hluav taws xob ntawm 120V / 240 V mus rau hauv lub zog hluav taws xob uas khiav ntawm 20-40 Khz thiab qhov hluav taws xob ntawm 1300 V. Lub zog no tau muab rau lub transducer, uas siv lub ncoo piezoelectric ceramic los hloov hluav taws xob lub zog rau kev siv tshuab kev co, uas yog, thaum lub siab hloov tam sim no hla los ntawm piezoelectric ceramic, piezoelectric ceramic ua kom muaj kev cuam tshuam kev ua haujlwm txawv.
Lub tshuab hloov khoom xa cov kev co mus rau ntawm qhov tsis tswg ntxiv. Kev hloov pauv nthwv zog nthuav dav ntawm ntau yam ntawm cov yoj ultrasonic thiab txuas ntxiv mus rau nws xa mus rau lub taub hau vuam. Lub taub hau vuam txuas ntxiv txuas ntxiv ntawm qhov loj ntawm ultrasonic yoj thiab los rau hauv kev sib cuag nrog feem.
Lub zog hloov mus rau vuam pas nrig txoj hauj lwm ntawm sib dhos ua ob ntu. Vim tias cov vuam vuam raug tsim nrog cov ntsiab lus ntse, lub zog tau sau ntawm cov ntsiab lus ntse, thiab kev sib txhuam thiab kub yog tsim nyob rau hauv siab. Tshav kub yog tsim los ntawm ob hom kev sib txhuam, ib qho yog qhov kev sib txhuam sab hauv nruab nrab ntawm qhov siab thiab sab ntawm cov khoom, thiab lwm qhov yog sab hauv molecular txhuam ntawm cov khoom. Nws yog vim tias lub tshav kub ua los ntawm kev sib txhuam uas qhov chaw ntawm sab saud thiab qis dua yaj thiab koom ua ke ntawm qhov chaw vuam.
Rau cov khoom qub, muaj peb yam uas txiav txim siab txog cua sov: zaus, qhov dav thiab cov vuam siab. Rau cov khoom siv uas twb muaj lawm, xws li 15 Khz, 20 kHz, 30 Khz lossis 40 Khz, cov zaus siv tas. Yog li no, qhov tso cua sov feem ntau tuaj yeem hloov los ntawm kev vuam siab. Feem ntau, ua haujlwm siab dua, qhov cua sov tawm ceev dua. Tsis tas li, koj kuj tuaj yeem hloov kho qhov tau txais, zoo li lub siab, qhov ntau dua, kom ntau dua li qhov cua kub ceev.
Ntawm chav kawm, ntau dhau ntawm lub siab thiab cov dav dav kuj tseem yuav muaj qhov tsis zoo ntawm cov hlau tsis zoo, xws li cov khoom tsis zoo, xau dej, tawg thiab txeej. Yog li no, ultrasonic vuam yuav tsum ua kom tiav cov txheej txheem ntawm cov txheej txheem tsis tau. Tom qab txiav txim siab rau cov kev ntsuas no, vuam txheej txheem tuaj yeem ncav qhov tsim tawm, thiab qhov nrawm yog siab, thiab lub zog vuam muaj zog. Qhov no yog vim li cas vim li cas ultrasonic vuam siv dav hauv kev tsim ntau yam.
Tus nqi ntawm cov cua sov uas xav tau rau vuam nyob ntawm cov khoom siv, vuam tsim thiab cov cuab yeej siv. Cov txheej txheem ib txwm ntawm kev tswj cov cua sov yog los ntawm lub sijhawm, uas yog, vuam rau qee lub sijhawm, xws li 0.2 ~ 1s (feem ntau tsawg dua 1s). Txawm li cas los xij, hnub no' s ultrasonic vuam cuab yeej tseem tuaj yeem tsim thiab soj ntsuam vuam nrug, lub zog thiab lub zog. Hauv cov neeg ua haujlwm tau kawm tau zoo, cov txwv kuj tuaj yeem hloov kho raws li qhov xwm txheej tiag tiag thiab cov khoom siv sib txawv, thiaj li ua kom tau txais txoj haujlwm vuam zoo. Qhov no kuj zoo heev txhim kho qhov hloov tau yooj yim thiab kev ntseeg siab ntawm vuam.
