Thaum tshav kub kub ntawm Ultrasonic Vuam Tshuab Tsim?
Ultrasonic vuam tshuab muaj qhov zoo ntawm kev lag luam, kev cia siab, thiab kev sib koom ua ke yooj yim automation, thiab yog ib qho cuab yeej siv rau cov yas vuam.
Tsis zoo li cov khoom siv hluav taws xob uas tsim hluav taws xob hauv kev sib cuag nrog cov yas, ultrasonic tooj liab sib txuas ua kom sov los ntawm kev txau.
1. Amplitude, zaus thiab wavelength
Nyob rau hauv ultrasonic welding, longitudinal nthwv dej propagate ntawm high frequencies, uas ua rau tsawg-amplitude mechanical vibrations. Lub zog hluav taws xob ntawm lub tshuab vuam yog hloov mus rau hauv lub tshuab hluav taws xob rau kev sib txuas lus. Txhawm rau nkag siab txog kev sib raug zoo ntawm amplitude, zaus, thiab wavelength, thiab seb lawv cuam tshuam li cas rau kev tsim hluav taws xob, peb yuav tsum txheeb xyuas cov khoom tseem ceeb ntawm ultrasonic welder.
Lub ntsiab Cheebtsam ntawm ib tug ultrasonic welder yog lub hwj chim qhov chaw, ib tug transducer, ib tug amplitude modulator (qee zaum hu ua amplitude converter) thiab lub taub hau vuam. Lub tshuab hluav taws xob hloov pauv ib qho 50-60Hz fais fab mov nrog qhov hluav taws xob ntawm 120V / 240V mus rau 20-40khz fais fab mov nrog qhov hluav taws xob ntawm 1300V. Lub zog no yog pub rau hauv lub sensor, uas hloov cov hluav taws xob hluav taws xob mus rau hauv cov tshuab kev vibrations siv lub disk zoo li piezoelectric ceramic uas ua rau muaj kev hloov pauv hloov thaum muaj hluav taws xob ntau dhau los ntawm nws.
Lub transducer xa cov kev co mus rau lub amplitude modulator. Lub amplitude modulator amplifies lub amplitude ntawm lub ultrasonic tsis thiab txuas ntxiv xa mus rau lub vuam taub hau. Lub taub hau txuas txuas txuas ntxiv rau qhov amplitude ntawm ultrasonic tsis thiab ua rau kev sib cuag nrog ib feem.
Lub zog yog pauv mus rau qhov chaw vuam ntawm ob qhov chaw ntawm lub rooj sib txoos. Txij li thaum lub electrode yog tsim los ua ib qho chaw uas lub zog yog concentrated, kev sib txhuam generates tshav kub nyob rau hauv siab. Thaum tshav kub kub yog tsim los ntawm kev sib txhuam ntawm sab sauv thiab qis ntawm cov khoom thiab nruab nrab ntawm cov molecules hauv cov khoom. Cov cua sov los ntawm kev sib txhuam melts lub sab sauv thiab sab qis thiab txuas lawv ua ke ntawm qhov chaw vuam.
2. Paub tus nqi cua sov
Rau tib yam khoom, peb yam txiav txim siab qhov cua sov: zaus, amplitude thiab vuam siab. Rau cov khoom siv uas twb muaj lawm xws li 15Khz, 20Khz, 30khz lossis 40Khz, qhov zaus raug kho. Yog li ntawd, cov cua kub feem ntau tuaj yeem hloov pauv los ntawm qhov vuam siab. Feem ntau, qhov siab dua, qhov cua sov ceev dua. Tsis tas li ntawd, koj tuaj yeem hloov qhov amplitude, ib yam li lub siab, qhov siab dua qhov amplitude, qhov cua sov sai dua.
Ntawm chav kawm, kev siab dhau thiab amplitude kuj tuaj yeem cuam tshuam qhov zoo ntawm cov khoom siv, xws li cov khoom degradation, leaks, tawg thiab nchuav. Yog li ntawd, ultrasonic vuam yuav tsum tau ib tug txheej txheem ntawm cov txheej txheem parameter optimization. Tom qab cov txheej txheem vuam tsis raug txiav txim siab, cov txheej txheem vuam tuaj yeem ua tiav cov khoom ruaj khov ntawm kev kub ceev thiab lub zog siab. Qhov no yog vim li cas ultrasonic vuam yog dav siv nyob rau hauv loj ntau lawm.
3. Lub sij hawm, nyob deb, lub zog thiab lub zog
Lub tshav kub xav tau rau vuam nyob ntawm cov khoom siv, vuam tsim thiab cov khoom specifications. Cov txheej txheem thermal tswj ib txwm yog vuam raws li lub sijhawm hom, uas yog, vuam rau ib lub sijhawm, xws li 0.2-1s (feem ntau tsawg dua 1s). Txawm li cas los xij, niaj hnub no cov cuab yeej siv ultrasonic vuam feem ntau kuj tso cai rau kev teeb tsa thiab kev saib xyuas ntawm vuam nrug, lub zog thiab lub zog. Cov neeg ua haujlwm tau txais kev cob qhia kom raug kuj tuaj yeem kho qhov tsis sib xws rau cov txiaj ntsig zoo sib xws raws li cov xwm txheej tiag tiag thiab cov khoom sib txawv. Qhov no kuj zoo heev txhim kho qhov yooj thiab kev ntseeg tau ntawm vuam.
