Ntau tus neeg yuav laser npav tshuab lossis ob txhais tes laser npav tshuab. Lawv tsis' tsis paub yuav txiav txim qhov zoo ntawm laser npav tshuab. Feem ntau, qhov zoo thiab kev ua tau zoo ntawm lub tshuab laser npav yog ncaj qha txiav txim siab los ntawm cov khoom siv ntawm kev kos. Nyob rau hauv qhov tseeb, qhov no yog unscientific, vim hais tias laser npav yuav hloov lub marking ceev, marking nyhuv thiab kos lub hwj chim raws li cov khoom siv. Rau kev ua laser npav, lub tswv yim ntawm Xiaobian yog los ntsuas nws cov kev ua tau zoo feem ntau los ntawm cov hauv qab no:
1. Lub cim nto yog du yam tsis muaj nkig puas
Thaum lub tshuab fiber ntau laser npav cim lub phaj tuab ntawm kev kub ceev, cov hlau molten yuav tsis tshwm nyob rau hauv qhov chaw nyob hauv qab ntawm lub laser beam, tab sis nws yuav tsum tau txau los ntawm lub laser beam. Raws li qhov tshwm sim, qhov nkhaus tsim ntawm qhov cim ntug ze ze ua raws li lub teeb txav laser. Yuav kom daws tau qhov teeb meem no, peb tsuas tuaj yeem txo qhov ceev ntawm qhov kawg ntawm cov txheej txheem kos npe, thiaj li yuav tshem tawm cov kab ntau lawm.
2. Qhov luaj li cas ntawm qhov sib txawv
Lub cim dav yog nqaim, uas feem ntau cuam tshuam nrog txoj kab uas hla ntawm lub laser beam chaw. Feem ntau hais lus, qhov dav dav ntawm optical fiber ntau laser npav tshuab tsis cuam tshuam rau cov cim zoo. Lub cim dav muaj qhov cuam tshuam tseem ceeb, ua ib feem ntawm cov ntaub ntawv teeb tsa tshwj xeeb. Qhov no yog vim qhov kev txiav dav txiav txim siab sab hauv nrog cov contour me tshaj plaws. Thaum lub thickness ntawm lub phaj nce, lub cim dav yuav nce. Yog li ntawd, txhawm rau kom ntseeg tau tias qhov tseeb tib yam, txawm tias qhov dav dav npaum li cas, lub workpiece yuav tsum tsis tu ncua hauv thaj chaw ua haujlwm ntawm lub tshuab laser npav.
3. Cov nyhuv kub ntawm cov khoom siv kos npe
Raws li cov khoom siv ntawm thermal marking processing, optical fiber ntau laser npav tshuab yog ua kom muaj kev cuam tshuam thermal ntawm cov ntaub ntawv hlau hauv cov txheej txheem siv, uas feem ntau suav nrog peb yam:
ib. Thaum tshav kub kub cuam tshuam cheeb tsam
b. Pitting thiab corrosion
c. Khoom deformation
Lub tshav kub cuam tshuam cheeb tsam yog hais txog thaj chaw rhuab raws qhov chaw nyob hauv laser npav. Nyob rau tib lub sijhawm, cov qauv ntawm cov hlau hloov. Piv txwv li, qee cov hlau tawv tawv. Lub tshav kub cuam tshuam qhov chaw hais txog qhov tob ntawm thaj chaw uas cov qauv sab hauv hloov pauv; Kev nyuaj siab thiab corrosion muaj qhov cuam tshuam tsis zoo rau ntawm qhov chaw ntawm qhov cim cim thiab cuam tshuam rau qhov pom. Lawv tshwm sim nyob rau hauv cov cim tsis raug uas yuav tsum tau zam nyob rau hauv dav dav; Thaum kawg, yog tias kos npe ua rau qhov kub hnyiab, nws yuav deform. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev ua haujlwm zoo vim tias cov contours thiab cov khoom sib txuas feem ntau tsuas yog ob peb feem kaum ntawm ib millimeter dav. Tswj lub zog laser thiab siv luv luv laser pulses tuaj yeem txo cov cua sov tiv thaiv thiab tsis txhob deformation.
Ntxiv rau cov hauv paus ntsiab lus saum toj no, lub xeev thiab qhov kawg tsim ntawm cov txheej txheem molten nyob rau hauv cov txheej txheem ntawm laser npav ncaj qha cuam tshuam rau saum toj no kev soj ntsuam zoo indexes.
Qhov saum npoo roughness ntawm laser npav feem ntau yog nyob ntawm peb yam hauv qab no:
1. Adjustable txheej txheem tsis thaum lub sij hawm kos npe, xws li lub hwj chim, cim ceev, auxiliary gas hom thiab siab, thiab lwm yam;
2. Inherent parameters ntawm lub cim system, xws li chaw hom, focal ntev, thiab lwm yam;
3. Lub cev tsis zoo ntawm cov khoom siv, xws li laser absorptivity, melting point, viscosity coefficient ntawm molten hlau oxide, nto nro ntawm hlau oxide, thiab lwm yam.
Tsis tas li ntawd, lub thickness ntawm machined qhov chaw kuj muaj kev cuam tshuam zoo rau saum npoo ntawm laser npav. Raws li kev hais lus, qhov me me ntawm qhov tuab ntawm cov hlau ua haujlwm, qhov siab dua qhov roughness qib ntawm cov cim nto. Yog li ntawd, yuav thiab muag laser npav tshuab los ntawm cov kws tshaj lij laser manufacturers yog qhov kev xaiv zoo tshaj plaws.
