Nrog rau kev nthuav dav ntawm kev siv tshuab laser niaj hnub no, qhov kev thov ntawm laser nyob rau hauv kev lag luam sib txawv yog ntau qhov tob. Raws li ib qho ntawm cov thev naus laus zis thev naus laus zis hauv kev lag luam, laser vuam tshuab tsis tsuas yog daws cov kev ua tsis tiav hauv kev ua qub, tab sis tseem ua rau ntau qhov kev sib tsoo ntawm cov txheej txheem. Dab tsi yog cov yam ntxwv lub zog ntawm laser siv nyob rau hauv laser vuam cov khoom siv hauv cov txheej txheem vuam?
Lub hauv paus ntsiab lus nyob rau hauv laser vuam tshuab: lub teeb qhov chaw ntawm laser vuam yog laser lub teeb-emitting diode, uas tuaj yeem raug tsom mus rau qhov tseeb sib koom nrog cov cam ua ke los ntawm cov kho qhov muag. Qhov zoo ntawm laser vuam yog tias nws tuaj yeem tswj tau kom zoo thiab ua kom lub zog ntawm qhov tsim nyog rau lub zog vuam. Nws yog tsim rau xaiv reflow soldering txheej txheem lossis siv tin hlau txuas.
Txog rau laser vuam, feem ntau ntseeg tau hais tias lub vuam qhov tob yog qhov ncaj qha kab nrog lub zog laser. Cov nqaj hom txiav txim siab qhov faib hluav taws xob ntawm qhov ua kom pom tseeb, uas muaj qhov cuam tshuam tseem ceeb ntawm kev ua cov laser.
Cov no yog cov yam ntxwv lub zog ntawm txoj kab teeb ntawm lub laser vuam tshuab. Tsis tas li ntawd, lub tshuab welding laser tsis tas yuav siv cov electrodes, thiab tsis muaj kev txhawj xeeb txog cov pa phem electrode lossis kev puas tsuaj. Cov nqaj hom txiav txim siab qhov faib hluav taws xob ntawm qhov ua kom pom tseeb, uas muaj qhov cuam tshuam tseem ceeb ntawm kev ua cov laser.
Thaum lub laser nqaj yog qhov yooj yim hom, qhov weld qhov siab tshaj plaws thiab qhov tob qhov dav dav piv tau. Cov kev txiav txim siab ntau dua ntawm cov nqaj hom, qhov ntau qhov sib cais ntawm cov nqaj zog lub zog faib tau, thiab cov hlau tsis zoo tuaj yeem ua kom tsis zoo. Tus nqi ntau dua K ntawm nqaj, qhov zuj zus qhov tsis zoo thiab qhov me dua qhov tob qhov sib piv ntawm qhov weld. Nyob rau hauv laser welding, lub luag haujlwm tseem ceeb yog laser lub zog ceev tus nqi. Laser welding tshuab yog vim tias cov khoom sib txawv muaj qhov tseem ceeb lub zog ceev ntawm qhov pib. Tsuas yog thaum lub zog ceev ntawm laser ua kom pom tseeb tshaj qhov tus nqi ntawm no tuaj yeem" keyhole nyhuv" tau tsim thiab qhov tob tob vuam tuaj yeem tau txais.
Cov yam ntxwv lub zog ntawm laser nqaj suav nrog lub zog thiab lub zog ntawm cov kab teeb laser, txuas ntxiv mus / tso tawm cov zis thiab polarization ntawm laser nqaj. Vim tias nws tsis yog qhov sib tiv tauj vuam txheej txheem, qhov hnav thiab deformation ntawm lub tshuab tuaj yeem raug txo kom tsawg. Cov yam ntxwv lub zog ntawm laser vuam tshuab feem ntau suav nrog lub yoj, lub zog thiab qhov ntom ntawm laser nqaj.
Cov kev sib raug zoo ntawm cov cuab yeej ua tau zoo ntawm laser vuam thiab cov yam ntxwv ntawm hom nqaj, uas suav nrog qhov nqaj zoo, hom nqaj thiab lub zog faib cov nqaj hla ntu. Lub zog ntom ntom ntawm lub qhov tsis yog tsuas yog ntsig txog qhov tsis zoo ntawm lub zog tsis sib xws, tab sis kuj tseem ua rau lub zog siab tshaj plaws, uas tau txheeb ze rau qhov kev faib tawm ntawm lub zog ib puag ncig.
