Ultrasonic hlau vuam tau yuam kev nyob rau hauv 1830s. Thaum lub sij hawm ntawd, thaum tam sim no qhov chaw vuam electrode tau ntxiv rau qhov kev kuaj ultrasonic vibration, nws tau pom tias nws tuaj yeem welded yam tsis muaj tam sim no, yog li ultrasonic hlau txias vuam tshuab tau tsim. Txawm hais tias ultrasonic vuam tau pom ua ntej, kom deb li deb, nws cov txheej txheem ntawm kev txiav txim tseem tsis tau meej. Nws zoo ib yam li kev sib txhuam vuam, tab sis muaj qhov sib txawv. Ultrasonic vuam lub sij hawm luv luv thiab qhov kub thiab txias yog qis dua recrystallization; Nws kuj yog qhov sib txawv ntawm lub siab vuam, vim tias lub siab zoo li qub tau siv ntau dua li qhov siab vuam. Nws yog feem ntau ntseeg hais tias nyob rau hauv thawj theem ntawm cov txheej txheem ultrasonic vuam, cov oxide ntawm cov hlau nto yog tangentially vibrated, thiab lub protruding ib feem ntawm cov ntxhib saum npoo ua dua microwelding thiab kev puas tsuaj cov txheej txheem los ua kom cov cheeb tsam sib cuag thiab nce qhov kub ntawm qhov vuam cheeb tsam siab, yas deformation tshwm sim nyob rau hauv lub interface ntawm lub weldment. Nyob rau hauv txoj kev no, thaum lub siab sib cuag nyob ze rau ib leeg mus rau qhov kev ncua deb uas lub atomic gravity ua tau, ib tug solder sib koom ua ke yog tsim. Yog hais tias lub sij hawm vuam ntev dhau lawm, los yog lub amplitude ntawm ultrasonic yoj loj heev, lub vuam lub zog yuav raug txo, los yog puas.
Nta ntawm ultrasonic hlau vuam
Cov yam ntxwv ntawm ultrasonic hlau vuam yog: tsis tas yuav tsum tau flux thiab sab nraud cua sov, tsis muaj deformation vim tshav kub, tsis muaj residual kev nyuaj siab, thiab tsis tshua muaj yuav tsum tau rau pre-welding kev kho mob ntawm lub welding nto. Tsis tsuas yog cov hlau zoo sib xws tab sis kuj cov hlau tsis sib xws tuaj yeem raug welded. Cov nplooj nyias nyias los yog filaments tuaj yeem welded rau cov phaj tuab. Ultrasonic welding muaj zog tsawg dua li qhov vuam tam sim no, thiab feem ntau yog siv rau vuam cov coj ntawm transistors lossis kev sib xyaw ua ke. Thaum siv rau kev sib khi vuam ntawm cov tshuaj thiab cov khoom tawg, nws tuaj yeem zam qhov dav dav vuam los ntawm cov tshuaj lom neeg vim cov khoom tawg, thiab yuav tsis tawg vim cua sov thiab lwm yam.
