Laser welding ntawm qhov chaw precision yog nqa tawm los ntawm kev siv lub laser nqaj tsom uas muaj lub zog loj ntawm lub ntsej muag monochromatic photon ntws raws li cov khoom siv cua sov. Qhov vuam txheej txheem no feem ntau suav nrog kev txuas ua hluav taws xob laser vuam thiab cov mem hluav zog laser vuam. Qhov zoo ntawm laser vuam yog tias nws tsis tas yuav tsum tau nqa tawm hauv lub tshuab nqus tsev, tab sis qhov tsis zoo yog tias lub zog quab yuam tsis muaj zog npaum li hluav taws xob nqaj hlau vuam.
Lub laser welding ntawm precision qhov chaw tuaj yeem tswj lub zog, kom nws tuaj yeem paub qhov vuam ntawm precision microdevices. Nws tuaj yeem siv rau ntau tus hlau, tshwj xeeb rau qee qhov nyuaj rau weld hlau thiab cov hlau tsis zoo.
Kev tsim hluav taws xob ntawm lub vuam laser rau qhov ntsuas qhov tseeb: tib lub yoj yoj, zaus, thiab kev taw qhia ntawm lub teeb ntom nti tsim thaum cov khoom siv zoo siab heev.
Cov yam ntxwv ntawm laser vuam rau qhov tseeb: nws muaj monochromaticity zoo, kev qhia ua kom zoo, thiab lub zog ua kom muaj zog. Tom qab lub laser tau xa lossis tsom rau ntawm daim iav, lub zog ntawm lub ntsej muag muaj qhov tsawg dua 0.01mm thiab lub zog ceev txog 1013w / cm2 tuaj yeem tau txais, uas tuaj yeem siv los ua cov cua kub rau vuam, txiav, drilling, thiab kho saum npoo. Laser cov ntaub ntawv suav nrog cov khoom siv ruaj khov, semiconductor, kua, roj, thiab lwm yam ntawm lawv, YAG cov khoom siv roj thiab cov pa roj carbon monoxide CO2 tau siv rau hauv cov hlau, txiav, thiab lwm yam txheej txheem kev lag luam.
Lub ntsiab zoo ntawm laser vuam rau qhov tseeb yog:
(1) Lub laser rau precision qhov chaw vuam tuaj yeem raug khoov thiab kis tau los ntawm cov qauv kev kho qhov muag xws li optical fiber thiab prism. Nws yog qhov tsim nyog rau vuam ntawm micro qhov chaw thiab lwm qhov chaw uas tsis yooj yim los ntawm lwm qhov kev vuam. Nws kuj tseem tuaj yeem ua welded nrog cov ntaub ntawv pob tshab.
(2) Nrog lub zog siv hluav taws xob ntau, nws tuaj yeem paub cov pa hluav taws xob siab, thiab thaj chaw tiv thaiv tshav kub thiab vuam kev cuam tshuam yog qhov tsawg heev, tshwj xeeb tshaj yog tsim nyog rau lub vuam ntawm cov khoom kub-nkag.
(3)Laser welding ntawm precision qhov chaw tsis cuam tshuam los ntawm lub tshuab hluav taws xob, tsis tsim hluav taws xob X, tsis xav tau kev tiv thaiv xau, thiab tuaj yeem siv rau vuam ntawm cov qauv loj
(4) Nws tuaj yeem txuas ncaj qha rau cov kab uas tsis muaj lub tshuab ntxig ua ntej, thiab tseem tuaj yeem txuas cov khoom tsis sib xws nrog cov khoom sib txawv ntawm lub cev.
Cov kev cuam tshuam tseem ceeb ntawm laser welding rau precision qhov chaw yog cov cuab yeej kim, qhov hloov hluav taws xob tsawg zog (5% - 20%), siab yuav tsum tau ua rau vuam interface ua, sib dhos, thiab chaw. Nyob rau tam sim no, nws yog feem ntau siv rau kev vuam ntawm microdevices hauv kev lag luam hluav taws xob thiab ntsuas kev lag luam, nrog rau cov vuam ntawm silicon steel los xij thiab zinc-plated steel daim hlau.
