Kev sib xyaw thiab kev yuav khoom ceev faj ntawm Ultrasonic Vuam Tshuab
Oct 18, 2022
Ultrasonic welding tshuab yog tsim los ntawm ultrasonic generator, ultrasonic transducer, ultrasonic horn, ultrasonic vuam taub hau thiab ib feem pab txhawb tooling. Thawj peb yog lub ultrasonic vuam system
1. Ultrasonic transducer
Kev ua haujlwm ntawm ultrasonic transducer yog hloov fais fab zaus (50 Hz lossis 60 Hz) voltage rau hauv ultrasonic zaus voltage. Lub transducer hloov lub ultrasonic zaus voltage los ntawm lub tshuab hluav taws xob rau hauv ultrasonic mechanical vibration ntawm tib zaus los ntawm cov nyhuv piezoelectric inverse. Thaum lub sinusoidal hluav taws xob teeb liab nkag mus rau lub transducer los ntawm lub electrode, lub piezoelectric piece expands thiab cog lus, tsim 15 ~ 20 μ Axial ncov mus rau lub ncov motion ntawm m. Thaum yuav khoom, xyuam xim rau cov khoom ntawm piezoelectric daim ntawv, uas txiav txim siab lub durability thiab tsis ua hauj lwm tus nqi ntawm lub transducer.
2. Ultrasonic horn
Lub horn muaj ob txoj haujlwm. Nws lub ntsiab muaj nuj nqi yog kom ua kom nrov rau cov neeg kho tshuab kev siv tshuab kev ua kom tiav ntawm qhov kawg ntawm transducer thiab hloov qhov kev co mus rau lub taub hau vuam. Lwm txoj haujlwm yog los muab txoj haujlwm ntawm cov khoom siv kho ntawm lub vuam xovxwm. Thaum lub zog ultrasonic siv rau lub transducer, lub horn kuj nthuav thiab sib cog lus. Ib yam li lwm qhov hauv cov khoom siv vuam, lub horn yog ib qho khoom siv tuning, yog li nws yuav tsum tau resonate ntawm ib zaus kom xa ultrasonic zog los ntawm transducer mus rau lub vuam taub hau. Txhawm rau ua lub luag haujlwm zoo, lub horn yuav tsum yog ib nrab wavelength lossis ib qho ntawm ntau qhov ntawm ib nrab wavelength ntawm ultrasonic hauv nws cov khoom tsim. Feem ntau ib nrab wavelength.
3. Ultrasonic vuam taub hau
Lub taub hau ultrasonic vuam yog ib feem ntawm cov khoom siv vuam uas muab lub zog rau cov khoom yuav tsum tau welded. Zoo li lub ultrasonic horn, lub vuam taub hau kuj yog ib tug tuning ntaus ntawv, uas kuj muab cov neeg kho tshuab amplification nyob rau hauv feem ntau daim ntaub ntawv, kom ntseeg tau tias muaj txaus amplitude nyob rau hauv lub kawg ntawm lub vuam taub hau kom paub vuam.
Tus tsim ntawm qhov chaw thiab cov pob qij txha yuav tsum welded txiav txim qhov loj thiab style ntawm vuam taub hau. Cov duab ntawm lub taub hau vuam yog qhov tseem ceeb vim tias qhov kev ntxhov siab tshwm sim los ntawm kev nthuav dav axial thiab kev cog lus ntawm lub taub hau vuam tuaj yeem ua rau tawg nyob rau hauv siab amplitude. Thaum yuav khoom, xyuam xim rau lub vuam taub hau qauv thiab kev siv tshuab, uas cuam tshuam rau kev tsim khoom ntawm lub vuam taub hau, thiab yog li cuam tshuam qhov sib txawv ntawm qhov system resonance. Ultrasonic vuam system muaj ob peb axial slots rau vuam taub hau ua, uas yog los xyuas kom meej tias lub amplitude nyob rau hauv lub longitudinal kev taw qhia.
Lub taub hau vuam ultrasonic yuav tsum tau tsim symmetrically kom deb li deb tau kom tsis txhob muaj qhov tsis sib npaug ntawm kev ntxhov siab thiab kev sib hloov kev co tshwm sim los ntawm asymmetry ntawm lub suab nthwv dej kis tau tus mob vim nws ua haujlwm nyob rau hauv cov xwm txheej ntawm kev vibration siab.
