Cov thev naus laus zis thev naus laus zis siv daim iav polarizing kom pom qhov laser nqaj thiab tsom rau nws lub zog ua kom pom lub zog tsim cov nqaj ntawm lub zog loj. Qhov kev tsom ntawm lub laser tawm los ntawm cov mem tes tam sim ntawd mus txog ntau txhiab degrees Celsius, thiab cov khoom siv hlau yuav yaj thiab yaj hauv ob peb milliseconds. Ib qho ua tau zoo yog ua qhov vuam ntawm cov tub ntxhais sib sau channel ntawm lub hnub ci tshav kub cov khoom siv hluav taws xob thiab cov xim kub siab xaiv txheej, thiab lub ntsiab lus vuam yog qhov nrug 3 mus rau 5 hli sib nrug ntawm lub hnub ci cua nqus txheej zaj duab xis txheej.
Nws yog cov uas tsis sib chwv, thiab nws tuaj yeem mus kev ntev ntev ua ntej nws muaj siab rau muab vuam, txiav thiab kho kev ua haujlwm kub. Nws cov txiaj ntsig yog tias nws tsis tas yuav ua kom lub siab ua haujlwm ntawm qhov chaw ua haujlwm tau txais welded, qhov kev hloov kho tag nrho yog qhov me me, thiab saum npoo ntawm cov cua sov-txheej yuav ua rau puas tsawg. Qhov no tseem yog qhov tseem ceeb vim li cas kev lag luam-kev cob qhia laser vuam yog zoo dua rau ultrasonic welding, tab sis laser vuam yuav hloov lub cev qauv ntawm cov khoom tau welded, txo lub zog kho tshuab, thiab muaj feem cuam tshuam ntawm cov thermal conductivity.
Ultrasonic vuam yog kev siv hluav taws xob ntau lub zog tsim los ntawm high-frequency mechanical kev co ntawm lub ultrasonic los plastically deform lub workpiece saum npoo thiab rhuav tshem cov txheej txheej hauv qab hauv siab, kom cov hlau welded tau txuas nrog lub cev ntawm qhov kub. Txawm hais tias ultrasonic welding rhuav tshem txog li 3% ntawm zaj duab xis txheej, nws yog qhov zoo ntawm qhov kub hloov ua haujlwm vim nws yog qhov txuas ntxiv tsis txuas tsis yaj. Nyob rau tib lub sijhawm, hais txog cov nqi ntawm cov khoom, ultrasonic welding muaj qee yam zoo. Ultrasonic vuam yog qhov tsim nyog rau cov khoom siv nyias. Lub ntsiab raws cov khoom lag luam tooj liab phaj hauv lub ntiaj teb no feem ntau nruab nrab ntawm 0.12mm thiab 0.2 hli. Txhawm rau xav txog cov nqi khoom siv, qee lub tuam txhab tam sim no xaiv txhuas daim hlau. -0.3mm tsis zoo.
Ultrasonic hlau chaw vuam tshuab yog siv rau lub vuam zoo ntawm cov hlau, thiab tuaj yeem ua tau ib qho-taw tes thiab ntau qhov taw qhia luv vuam ntawm cov ntaub ntawv nyias ntawm cov hlau tsis huv xws li tooj liab, nyiaj, txhuas, thiab npib tsib xee. Nws tuaj yeem siv dav hauv fusible txuas lithium roj teeb. Vuam ntawm ntau yam duab xws li ncej. Lub vev xaib laser yog qhov tsim nyog rau cov khoom siv tuab, xws li tuab ntawm daim ntawv txhuas phaj feem ntau xaiv 0.4 hli, uas ua rau cov nqi ntau dua cov khoom siv. Ultrasonic vuam tshuab yog qhov tsim nyog rau vuam kuj tsim cov khoom lag luam, laser vuam yuav ncaj qha rau nyias. Lwm qhov tseem ceeb yog tias tus nqi ntawm laser vuam tshuab yog ob peb zaug ntau dua li nqi ntawm ultrasonic vuam tshuab.
