Yuav ua li cas lub Ultrasonic Vuam Tshuab tsim tshav kub?
Ultrasonic welding tshuab yog ib qho cuab yeej siv hauv kev lag luam yas vuam vim nws qhov zoo ntawm kev lag luam, kev ntseeg siab thiab kev sib koom ua ke yooj yim automation. Tsis zoo li cov khoom siv hluav taws xob, uas ua kom muaj cua sov hauv kev sib cuag nrog cov yas, ultrasonic vuam generates tshav kub los ntawm kev sib txhuam.
1. Amplitude, zaus thiab wavelength
Nyob rau hauv ultrasonic welding, longitudinal tsis yog kis nyob rau hauv daim ntawv ntawm high frequencies, uas ua rau cov neeg kho tshuab vibrations ntawm tsawg amplitude. Lub zog hluav taws xob ntawm lub tshuab vuam yog hloov mus rau hauv lub tshuab hluav taws xob rau kev sib txuas lus. Yuav kom nkag siab txog kev sib raug zoo ntawm amplitude, zaus thiab wavelength, thiab yuav ua li cas lawv cuam tshuam txog kev tsim hluav taws xob, peb yuav tsum nkag siab cov ntsiab lus tseem ceeb ntawm lub tshuab ultrasonic vuam.
Cov khoom tseem ceeb ntawm lub tshuab vuam ultrasonic yog lub tshuab hluav taws xob, lub tshuab hloov hluav taws xob, lub amplitude modulator (qee zaum hu ua horn) thiab lub taub hau vuam. Lub tshuab hluav taws xob hloov pauv lub zog 50-60Hz nrog qhov hluav taws xob ntawm 120V / 240V mus rau lub zog hluav taws xob ua haujlwm ntawm 20-40Khz nrog qhov hluav taws xob ntawm 1300V. Lub zog no yog nkag mus rau lub transducer, uas siv lub disc-shaped piezoelectric ceramic los hloov lub zog hluav taws xob mus rau hauv cov khoom siv hluav taws xob, uas yog, thaum lub zog hluav taws xob ntau dhau los ntawm piezoelectric ceramic, piezoelectric ceramic yuav ua rau muaj kev hloov pauv.
Lub converter xa cov kev co mus rau lub amplitude modulator. Lub amplitude modulator amplifies lub amplitude ntawm ultrasonic yoj thiab txuas ntxiv mus rau lub vuam taub hau. Lub horn tseem ua rau lub amplitude ntawm lub ultrasonic tsis thiab ua rau kev sib cuag nrog ib feem.
Thaum kawg, lub zog yog pauv mus rau qhov chaw welded tav ntawm ob qhov chaw ntawm lub rooj sib txoos. Vim hais tias cov vuam rib yog tsim los nrog ib tug ntse taw tes, lub zog yog concentrated nyob rau hauv lub point ntawm lub point, thiab kev sib txhuam kub yog generated nyob rau hauv lub siab. Cov cua sov no yog tsim los ntawm ob hom kev sib txhuam, ib qho yog kev sib txhuam ntawm cov khoom siv sab saud thiab qis, thiab lwm qhov yog kev sib txhuam ntawm cov khoom siv. Nws yog cov cua sov uas tsim los ntawm kev sib txhuam uas ua rau lub sab sauv thiab sab qis kom yaj thiab koom ua ke ntawm qhov chaw vuam.
2. Nkag siab 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 cov cav tov, qhov zaus yog tsau. Yog li cov cua kub feem ntau tuaj yeem hloov nrog lub vuam siab. Feem ntau, qhov siab dua, qhov cua sov ceev dua. Xwb, koj tuaj yeem sib txawv ntawm qhov amplitude, xws li nrog lub siab, qhov loj dua qhov amplitude, qhov ceev ntawm cua sov.
Tau kawg, kev siab dhau heev thiab amplitude kuj tuaj yeem cuam tshuam rau qhov zoo ntawm vuam, xws li ua rau cov khoom degradation, leaks, tawg, thiab flash. Yog li ntawd, ultrasonic vuam yuav tsum tau ib tug txheej txheem ntawm optimizing txheej txheem tsis. Tom qab cov kev ntsuas tau txiav txim siab, cov txheej txheem vuam tuaj yeem ua tiav cov zis ruaj khov nrog kev ceev ceev thiab siab vuam lub zog. Qhov no yog vim li cas ultrasonic vuam yog dav siv nyob rau hauv loj ntau lawm.
3. Lub sij hawm, nrug, muaj zog thiab lub zog
Tus nqi ntawm cov cua sov xav tau rau vuam nyob ntawm cov khoom siv, kev tsim vuam thiab cov khoom siv tshwj xeeb. Cov txheej txheem ntawm kev tswj cov cua sov yog vuam los ntawm lub sij hawm hom, uas yog, vuam rau ib lub sij hawm, xws li 0.2-1s (feem ntau tsawg dua 1s). Txawm li cas los xij, nrog cov cuab yeej siv ultrasonic vuam niaj hnub no, feem ntau tuaj yeem teeb tsa thiab saib xyuas vuam nrug, lub zog thiab lub zog. Nrog rau cov neeg ua haujlwm tau txais kev cob qhia kom raug, kev hloov pauv kuj tuaj yeem ua raws li cov xwm txheej tiag tiag thiab cov khoom sib txawv, uas ua rau muaj qhov zoo sib xws. Qhov no kuj zoo heev txhim kho qhov yooj thiab kev ntseeg tau ntawm vuam.
