Vuam raws ntawm lub tshuab ultrasonic welding
Nrog cov koob npe ntawm cov khoom siv ultrasonic welding, ntau thiab ntau dua cov khoom seem yas hloov los ntawm cov thev naus laus zis mus rau ultrasonic welding. Yog li cov hom khoom zoo li cas rau ultrasonic vuam
1. Lub tshav kub ua haujlwm tiv thaiv yuav tsum mus txog rau lub chaw melting ntawm qhov haujlwm tawm
Tom qab lub ultrasonic transducer hloov hluav taws xob lub zog rau hauv kev siv zog, nws ua los ntawm cov khoom siv molecules ntawm lub workpiece. Qhov acoustic tsis kam ntawm ultrasonic tsis nyob hauv cov khib nyiab me dua li uas hauv cov huab cua. Thaum suab ntas dhau los ntawm qhov sib koom ua haujlwm ntawm qhov haujlwm, qhov tawm tsam nyob rau hauv qhov sib txawv yog qhov loj. , Cov tshav kub tsim tau zoo heev. Qhov kub ua ntej tau mus txog qhov chaw melting ntawm lub workpiece, thiab tom qab ntawd ua ntawv thov rau qhov sib koom ua ke welded los ua ib qho siab. Lwm ntu ntawm cov haujlwm tsis tuaj yeem ua rau vim tsis muaj cua sov ua haujlwm.

2. Ob qhov chaw ua haujlwm yuav tsum yog weldable
Qee cov ntaub ntawv sib txawv tuaj yeem tau welded zoo, qee qhov tuaj yeem cia li fused, thiab qee qhov tsis tuaj yeem. Hauv txoj ntsiab cai, melting kis ntawm tib cov khoom siv tau tuaj yeem txuas, tab sis thaum lub ntsiab lus melting ntawm lub workpiece yuav tsum tau welded yog siab dua 350 ° C, ultrasonic vuam tsis haum. Txij li thaum ultrasonic tsis muaj vau tam sim ntawd yuav yaj cov molecules ntawm lub workpiece, lub hauv paus ntawm kev txiav txim siab yog tias lawv tsis tuaj yeem txuas tau zoo nyob hauv 3 vib nas this, yog li lwm cov txheej txheem vuam yuav tsum tau xaiv. Xws li kub phaj vuam. Feem ntau hais lus, ABS cov ntaub ntawv yooj yim rau weld, thaum nylon lossis PP cov ntaub ntawv yog qhov nyuaj rau weld.
3. Muaj qee qhov xav tau rau kev sib koom ua ke
Thaum muaj kev cuam tshuam hluav taws xob tam sim ntawd, qhov loj dua qhov chaw sib sau, qhov ntau dua qhov cuam tshuam ntawm lub zog, qhov tsis zoo ntawm cov vuam, thiab cov vuam tsis zoo. Ntxiv rau, cov ultrasonic tsis sib kis tau nyob rau hauv cov kev taw qhia ntev, thiab lub zog poob yog qhov sib npaug rau qhov kev ncua deb. Ntev-vuam yuav tsum tswj tsis pub dhau 6 cm. Lub vuam kab yuav tsum raug tswj nyob nruab nrab ntawm 30-80 vuam hlau, thiab lub phab ntsa tuab ntawm lub workpiece yuav tsum tsis pub tsawg dua 2 hli, txwv tsis pub nws yuav tsis muaj peev xwm txuas tau zoo, tshwj xeeb tshaj yog rau cov khoom lag luam uas yuav tsum muaj huab cua nruj.
4. Lub zog tsim tawm yuav tsum muaj tas mus li
Hauv cov txheej txheem tsim, cov zis muaj zog ntawm lub tshuab ultrasonic welding nyob ntawm qhov taub, tuab, khoom siv thiab piezoelectric ceramic ntawv. Thaum cov ultrasonic transducer tiav, lub zog loj tiav lawm. Ntsuas cov zis hluav taws xob yog qhov txheej txheem nyuaj. Qhov no tsis yog hais tias qhov loj dua ultrasonic transducer thiab ntau lub zog ultrasonic siv nyob rau hauv Circuit Court, ntau dua cov zis muaj zog. Nws xav tau txoj kev ntsuas uas tsim nyog siv los ntsuas qhov nws ua tau txawv.

5. Kev yuam kev ntawm lub tshuab ultrasonic welding
Yuav siv ntau npaum li cas rau lub zog siv, qhov oscillation zaus thiab qhov ntau ntau yuav tsum yog nyob ntawm cov khoom siv xws li qhov chaw ua haujlwm, xav txog thaj tsam ntawm lub vuam hlau, seb puas muaj cov khoom siv hluav taws xob hauv lub workpiece thiab seb puas muaj airtightness.
6. Xav tau kev soj ntsuam nruj
Tsoos ultrasonic pwm tuam ntxhab muaj cov txheej txheem tshuaj xyuas nruj rau cov khoom nkag, thiab kev ntsuas qhov ntev yog tom qab khoos phis tawj software simulation thiab kev kuaj xyuas. Cov khoom lag luam zoo. Cov txheej txheem no tsis tuaj yeem ua tiav hauv ib qho kev cob qhia ib txwm. Yog tias pwm tsim qauv tsis yog, qhov teeb meem tshuaj tiv thaiv yuav tsis pom tseeb thaum vuam cov khoom me me, thiab ntau yam luv luv yuav tshwm ntawm lub zog loj. Thaum muaj mob loj, lub zog hluav taws xob yuav raug ncaj qha.
