Laser vuam tshuab, tseem hu ua laser vuam tshuab thiab laser vuam tshuab, yog siv rau laser khoom ua. Raws li nws txoj kev ua haujlwm, feem ntau tuaj yeem muab faib ua laser pwm vuam tshuab (cov khoom siv laser vuam), tsis siv neeg laser vuam tshuab, hniav nyiaj hniav kub laser vuam tshuab, laser chaw vuam tshuab, fiber ntau kis laser vuam tshuab, galvanometer vuam tshuab, tes- tuav vuam tshuab, thiab lwm yam. tshwj xeeb laser vuam khoom muaj xws li sensor vuam tshuab, silicon steel ntawv laser vuam khoom, keyboard laser vuam khoom.
1. Laser vuam tshuab
Lub workpiece ntawm lub laser vuam tshuab sai sai melts thiab txawm vaporizes tom qab absorbing lub laser. Cov hlau molten tsim ib lub qhov me me laser beam nyob rau hauv qhov kev txiav txim ntawm chav siab, uas tuaj yeem ncaj qha teeb lub qhov hauv qab, ua rau lub qhov txuas ntxiv mus kom txog rau thaum lub zog siab hauv lub qhov yog sib npaug nrog qhov nro thiab lub ntiajteb txawj nqus ntawm cov kua hlau. Qhov no vuam hom muaj ib tug loj nkag thiab ib tug loj qhov tob rau dav piv. Thaum lub qhov tseem ceeb txav mus raws cov kev taw qhia vuam nrog lub laser beam, cov hlau molten nyob rau hauv pem hauv ntej ntawm lub qhov tseem ceeb ntawm lub laser vuam tshuab bypasses lub qhov tseem ceeb thiab ntws mus rau nram qab, tsim ib tug weld tom qab solidification.
2. Nkag siab qhov parameter nqis ntawm lub tshuab laser vuam
1) Laser zog ceev
Lub zog ceev yog ib qho tseem ceeb tshaj plaws hauv kev ua laser. Nrog lub zog ntau dua, nws tuaj yeem ua kom sov txheej txheej mus rau qhov kub thiab txias hauv microseconds, yog li tsim cov vaporization ntau. Yog li ntawd, lub zog siab ceev yog qhov tsim nyog rau kev tshem tawm cov khoom, xws li stamping, txiav thiab engraving. Rau qis zog ceev, nws yuav siv sij hawm ob peb milliseconds rau qhov kub thiab txias kom ncav cuag lub boiling point. Ua ntej txheej txheej vaporizes, txheej hauv qab mus txog qhov melting point, uas yog ib qho yooj yim los tsim zoo fusion vuam. Yog li ntawd, nyob rau hauv conductive laser vuam, lub hwj chim ceev yog nyob rau hauv ntau ntawm 104 ~ 106W / cm2. Beam qhov loj me yog ib qho tseem ceeb tshaj plaws ntawm kev hloov pauv hauv laser vuam, vim nws txiav txim siab lub zog ceev.
2) Cov khoom siv nqus cov nqi
Kev nqus ntawm laser los ntawm cov ntaub ntawv yog nyob ntawm qee yam khoom tseem ceeb ntawm cov khoom, xws li absorptivity, reflectivity, thermal conductivity, melting kub, evaporation kub, thiab lwm yam, uas qhov tseem ceeb tshaj plaws yog nqus.
Cov yam ntxwv uas cuam tshuam rau kev nqus ntawm cov ntaub ntawv rau cov kab teeb laser muaj xws li ob yam: ib qho yog cov khoom tiv thaiv. Tom qab ntsuas qhov absorptivity ntawm polished nto ntawm cov khoom, nws pom tau hais tias lub absorptivity ntawm cov khoom yog proportional rau lub square cag ntawm lub resistivity, thiab cov resistivity hloov nrog kub. Thiab hloov; Qhov thib ob, lub xeev saum npoo av (lossis tiav) ntawm cov khoom muaj qhov cuam tshuam tseem ceeb ntawm lub teeb pom kev zoo, thiab muaj kev cuam tshuam loj heev rau kev siv vuam. Cov hlau tsis muaj xws li ceramics, iav, roj hmab thiab yas muaj qhov nqus siab ntawm chav tsev kub, thaum cov ntaub ntawv hlau tsis zoo nyob rau hauv chav tsev kub kom txog thaum cov ntaub ntawv yaj lossis txawm tias deflate. Nws qhov nqus yuav tsuas yog nce ntau heev. Cov txheej txheem ntawm kev siv txheej txheej los yog tsim oxide zaj duab xis rau saum npoo yog zoo heev rau kev txhim kho qhov nqus ntawm lub teeb ci los ntawm cov ntaub ntawv.
3) Pulse zoo thiab dav
Pulse waveform yog ib qho teeb meem tseem ceeb hauv vuam, tshwj xeeb tshaj yog rau nyias phaj vuam. Thaum lub siab siv lub teeb hits cov khoom nto, ib feem ntawm lub zog ntawm cov hlau saum npoo yuav ploj los ntawm kev xav, thiab qhov kev cuam tshuam yuav hloov nrog qhov kub thiab txias. Thaum lub sijhawm ua haujlwm mem tes, qhov cuam tshuam ntawm cov hlau sib txawv heev.
Pulse width yog ib qho tseem ceeb ntawm cov mem tes vuam. Nws tsis yog tsuas yog ib qho tseem ceeb tsis txawv ntawm cov khoom tshem tawm thiab cov khoom siv melting, tab sis kuj yog ib qho tseem ceeb parameter txiav txim siab tus nqi thiab ntim ntawm cov khoom siv.
4) Qhov cuam tshuam ntawm defocus
Vim lub zog siab ceev ntawm qhov chaw nruab nrab ntawm lub laser tsom, nws yooj yim rau evaporate rau hauv qhov. Nyob rau hauv txhua lub dav hlau nyob deb ntawm lub laser tsom, lub hwj chim density tis yog sib xws. Muaj ob txoj kev defocusing: zoo defocusing thiab tsis zoo defocusing. Yog hais tias lub dav hlau focal nyob saum lub workpiece, nws yog qhov zoo defocusing, txwv tsis pub nws yog qhov tsis zoo defocusing. Raws li txoj kev xav geometrical optics, thaum qhov kev ncua deb ntawm qhov zoo thiab qhov tsis zoo ntawm lub dav hlau defocusing thiab vuam dav hlau sib npaug, lub zog ntom ntom ntawm cov dav hlau sib txuas yog kwv yees li qub, tab sis qhov tseeb cov duab ntawm lub pas dej weld tau sib txawv. Thaum lub defocusing yog qhov tsis zoo, qhov tob tob tuaj yeem tau txais ntau dua, uas muaj feem xyuam rau cov txheej txheem tsim ntawm lub pas dej molten.

c) Cov kev xav tau ntawm vuam thiab vuam tsis sib txawv rau cov khoom sib txawv.
d) Lub tshuab laser vuam yuav tsum muaj kev tiv thaiv los ntawm argon los tiv thaiv oxidation ntawm cov khoom tiav vuam, thiab cov khoom ua haujlwm welded zoo nkauj heev.
e) Parameters uas yuav tsum tau teem rau laser vuam tshuab fais fab mov: tam sim no {{0}}A, 0.1-20MS; zaus 0-50. Ib txwm vuam workpiece simulation tsis muaj raws li nram no: tam sim no: 90-120; mem tes dav: 4-6; zaus yog 5-10; thiab cov vuam tsis tau hloov kho raws li cov khoom siv thiab cov xwm txheej tiag tiag ntawm cov khoom ua haujlwm.
f) Thaum lub workpiece thiab tsis tau raug kho. Vuam tuaj yeem nqa tau thaum lub vuam focal ntev npaj txhij. Lub tshuab laser vuam siv lub teeb liab hloov los tswj cov zis laser.
3) Thaum kawg ntawm kev siv, xyuas cov khoom siv thiab tua nws
a) Tom qab siv, kaw cov plua plav tshem tawm, dej txias, argon lub tog raj kheej valve thiab lwm yam khoom siv ua ntu zus;
b) Tua lub hwj chim hloov thiab xyuas seb lub qhov hluav taws xob uas yuav tsum tau muab tua yog muab tua
4. Kev ceev faj rau kev siv lub tshuab laser vuam
1) Thaum lub sijhawm ua haujlwm ntawm lub tshuab laser vuam, thaum muaj xwm txheej ceev (dej xau, lub suab txawv txav ntawm lub laser, thiab lwm yam), nias qhov xwm txheej ceev tam sim ntawd thiab txiav tawm lub hwj chim sai;
2) Sab nraud circulating dej hloov ntawm laser vuam yuav tsum tau qhib ua ntej ua hauj lwm;
3) Txij li thaum lub laser system yog txias los ntawm dej thiab lub laser fais fab mov yog txias los ntawm huab cua, nws yog nruj me ntsis txwv tsis pub pib lub tshuab yog hais tias lub txias system tsis ua hauj lwm;
4) Tsis txhob rhuav tshem txhua qhov hauv lub tshuab ntawm qhov xav tau, tsis txhob vuam thaum lub qhov rooj ruaj ntseg ntawm lub tshuab qhib, tsis txhob ntsia ncaj qha ntawm lub laser lossis cuam tshuam lub laser nrog koj ob lub qhov muag thaum lub laser ua haujlwm, thiab tsis txhob fim. lub laser vuam taub hau nrog koj ob lub qhov muag kom tsis txhob raug mob qhov muag;
5) Cov khoom tawg yooj yim thiab tawg yuav tsum tsis txhob muab tso rau ntawm txoj kev laser lossis qhov chaw uas lub teeb laser tuaj yeem ncav cuag, kom tsis txhob muaj hluav taws kub thiab tawg;
6) Thaum lub tshuab ua haujlwm, lub voj voog yog nyob rau hauv lub xeev ntawm high voltage thiab muaj zog tam sim no. Nws yog txwv tsis pub kov cov khoom siv hluav taws xob hauv lub tshuab thaum ua haujlwm;
5. Siv lub tshuab laser vuam yam xyuam xim
Thaum ua haujlwm ntawm cov khoom siv laser vuam, tus neeg teb xov tooj yuav tsum tau them sai sai rau nws cov txheej txheem kev ua haujlwm thiab cov txheej txheem, thiab muaj peev xwm debug hauv ib txoj kev tshwj xeeb. Cov kev cai tshwj xeeb rau cov khoom siv lossis qhov sib txawv ntawm cov txheej txheem vuam yuav ua rau kev ua haujlwm tsis zoo ntawm cov khoom siv. Tsuas yog nyob rau hauv txoj kev no tuaj yeem siv lub tshuab laser welding kom muaj kev ua haujlwm zoo thiab ua rau peb muaj txiaj ntsig zoo thiab cov qauv tsim khoom.
