Cov ntsiab lus thiab cov yam ntxwv ntawm kev ua laser

1. Cov ntsiab lus ntawm kev ua laser

Laser ua yog lub laser beam irradiated rau saum npoo ntawm lub workpiece, nrog rau lub laser lub siab zog txiav, yaj cov ntaub ntawv, thiab hloov qhov nto ntawm cov khoom. Vim tias kev ua haujlwm laser tsis yog kev sib cuag, cov cuab yeej yuav tsis ua rau muaj kev sib txhuam ncaj qha rau ntawm qhov chaw ua haujlwm, yog li kev ua haujlwm ntawm laser ceev ceev heev, cov khoom siv cuam tshuam los ntawm tshav kub ntau me dua thiab yuav tsis ua suab nrov. Txij li thaum lub zog ntawm lub laser beam thiab txav ceev ntawm lub nqaj tuaj yeem hloov kho, kev ua laser tuaj yeem siv rau ntau qib thiab ntau yam.

2. Cov yam ntxwv ntawm kev ua laser

Cov yam ntxwv tseem ceeb ntawm laser txiav txim siab qhov zoo ntawm laser hauv kev ua haujlwm:

(1) Vim tias nws tsis yog kev sib cuag, thiab lub zog ntawm lub zog loj laser beam thiab nws txoj kev txav ceev yog kho tau, nws tuaj yeem ua tiav ntau hom kev ua haujlwm.

(2) Nws tuaj yeem ua ntau yam hlau thiab cov hlau tsis muaj hlau, tshwj xeeb tshaj yog muaj zog hardness, siab brittleness, thiab siab melting point cov ntaub ntawv.

Laser ua txheej txheem tsis muaj "tawv" hnav, tsis muaj "txiav quab yuam" ntawm lub workpiece.

(3) Nyob rau hauv cov txheej txheem ntawm laser ua, lub zog ceev ntawm lub laser beam yog siab, kev ceev ceev, thiab nws yog nyob rau hauv lub zos ua, uas tsis muaj kev cuam tshuam los yog me ntsis cuam tshuam rau cov tsis-laser irradiation qhov chaw. Yog li ntawd, lub tshav kub cuam tshuam qhov chaw me me, thermal deformation ntawm lub workpiece yog me me, thiab cov khoom tom ntej yog me me.

(4) Nws tuaj yeem ua cov khoom ua haujlwm hauv lub thawv kaw los ntawm qhov nruab nrab pob tshab.

Vim hais tias cov nqaj laser yog ib qho yooj yim rau kev taw qhia, thiab sib sau ua ke kom ua tiav cov kev taw qhia ntawm kev hloov pauv, thiab yooj yim rau kev koom tes nrog kev tswj cov lej, kev ua haujlwm nyuaj, nws yog txoj kev ua haujlwm yooj yim heev.

(5) Kev siv laser ua, kev ua haujlwm siab ntau lawm, txhim khu kev qha zoo, thiab kev lag luam zoo.

Laser Technology

Lub laser beam yog siv rau ntau yam khoom siv, xws li xuas nrig ntaus, txiav, txiav, vuam, kho cua sov, thiab lwm yam. Laser ua muaj ntau yam zoo:

(1) laser zog ceev, lub workpiece nqus laser kub sai thiab melting los yog vaporization, txawm tias lub melting point yog siab, hardness thiab brittle cov ntaub ntawv (xws li ceramics, pob zeb diamond, thiab lwm yam) kuj siv tau rau laser ua;

(2) Laser lub taub hau thiab workpiece tsis nyob rau hauv kev sib cuag, tsis muaj machining cuab tam hnav teeb meem;

(3) lub workpiece tsis muaj zog, tsis yooj yim rau paug;

(4) Nws tuaj yeem ua cov khoom txav mus los lossis cov khoom ntim hauv lub khob iav;

(5) Lub divergence Lub kaum sab xis ntawm lub laser beam yuav tsawg tshaj li 1 milliarc, qhov chaw txoj kab uas hla yuav me me mus rau micron magnitude, lub sij hawm ua hauj lwm yuav luv luv rau nanosecond thiab picosecond, tib lub sij hawm, lub nruam tso zis zog ntawm lub siab. -lub zog laser tuaj yeem ncav cuag kilowatt mus txog kaum kilowatt magnitude, yog li lub laser tsis yog tsuas yog haum rau precision micro-machining, tab sis kuj haum rau cov khoom loj loj;

(6) Lub laser beam yog ib qho yooj yim los tswj, yooj yim los ua ke nrog precision machinery, precision ntsuas tshuab thiab hluav taws xob computers, kom ua tiav qib siab ntawm automation thiab machining raug;

(7) Nyob rau hauv ib puag ncig hnyav lossis lwm tus neeg nyuaj rau kev nkag mus rau qhov chaw, tuaj yeem siv rau cov neeg ua haujlwm laser.

1. Laser drilling

Pulse laser siv tau rau drilling, pulse dav yog {{0}}.1 ~ 1 ms, tshwj xeeb tshaj yog haum rau drilling micro qhov thiab tshwj xeeb-zoo li tus qhov, thiab lub aperture yog hais txog 0.005 ~ 1 hli. Laser drilling tau siv dav hauv kev saib thiab ntsuas lub pov haum bearing, pob zeb diamond hlau kos duab tuag, tshuaj fiber ntau spinneret thiab lwm yam haujlwm ua haujlwm.

2. Laser txiav, segmentation, thiab ntawv

Hauv kev tsim nkoj, kev tsim tsheb, thiab lwm yam kev lag luam, qhov txuas ntxiv CO2 laser feem ntau yog siv los txiav cov khoom loj, uas tuaj yeem tsis tsuas yog ua kom muaj qhov tseeb ntawm qhov nkhaus nkhaus tab sis kuj muaj kev ua haujlwm siab. Kev txiav ntawm cov khoom me me feem ntau yog siv hauv nruab nrab lossis qis zog lub xeev lasers lossis CO2 lasers. Nyob rau hauv microelectronics, lub laser feem ntau yog siv los hlais silicon los yog slit, ceev ceev, me me tshav kub cuam tshuam cheeb tsam. Lub laser tuaj yeem siv rau ntawm cov raj xa dej ntawm cov ntawv ua haujlwm lossis kos npe, tsis cuam tshuam rau qhov ceev ntawm cov kav dej, thiab cov cim tuaj yeem khaws cia mus tas li.

3. Laser fine-tuning

Txhawm rau hloov hluav taws xob tsis zoo (xws li tus nqi tsis kam, capacitance, thiab resonant zaus), nruab nrab thiab me me fais fab laser yog siv los tshem tawm qee cov ntaub ntawv ntawm cov khoom siv hluav taws xob. Laser fine-tuning precision yog siab, ceev ceev, thiab haum rau loj ntau lawm. Los ntawm kev siv lub hauv paus ntsiab lus zoo sib xws, lub npog ntsej muag ntawm IC puas tuaj yeem kho tau, lub cim xeeb IC tuaj yeem kho tau los txhim kho cov txiaj ntsig, thiab gyroscope tuaj yeem hloov kho kom raug rau qhov sib npaug zoo.

4. Laser vuam

Laser vuam muaj lub zog siab, me me thermal deformation, zoo sealing, thiab tuaj yeem welded nrog ntau qhov sib txawv thiab cov khoom, nrog rau cov ntsiab lus siab melting (xws li ceramics) thiab cov ntaub ntawv oxidized yooj yim. Laser-welded pacemakers muaj kev sib khi zoo, lub neej ntev, thiab me me.

5. Laser kev kho cua sov

Los ntawm irradiating cov ntaub ntawv nrog ib tug laser, xaiv lub wavelength tsim nyog, thiab tswj irradiation lub sij hawm thiab lub zog ceev, lub nto ntawm cov ntaub ntawv yuav tsum melted thiab recrystallized kom tiav lub hom phiaj ntawm quenching los yog annealing. Qhov zoo ntawm kev kho cua sov laser yog tias qhov tob ntawm kev kho cua sov tuaj yeem tswj tau, cov khoom tuaj yeem xaiv thiab tswj tau, lub workpiece deformation yog me me, cov duab ntawm cov khoom sib txawv thiab cov khoom tuaj yeem ua tiav, thiab sab hauv phab ntsa ntawm lub qhov muag tsis pom. thiab qhov tob tob tuaj yeem ua tiav. Piv txwv li, lub neej ntawm lub tog raj kheej piston tuaj yeem txuas ntxiv tom qab kev kho cua sov laser; Silicon cov ntaub ntawv puas los ntawm ion bombardment tuaj yeem rov qab los ntawm kev kho cua sov laser.

6. Kev kho mob hnyav

Laser saum npoo ntxiv dag zog rau kev siv tshuab yog ua los ntawm ob txheej txheem siab zog ceev cua sov thiab ceev nws tus kheej txias ntawm lub workpiece. Nyob rau hauv lub laser nto ntxiv dag zog rau cov ntaub ntawv hlau, thaum lub zog ceev ntawm lub laser beam nyob rau hauv qis kawg, nws yuav siv tau rau lub nto theem transformation ntxiv dag zog rau cov ntaub ntawv hlau. Thaum lub zog ceev ntawm lub laser beam nyob rau hauv siab kawg, qhov chaw nto ntawm lub workpiece yog heev ib tug txav sib txawv, uas yuav ua kom tiav ib tug series ntawm metallurgical txheej txheem. Xws li deg remelting, nto carburizing, nto alloying, thiab nto cladding. Cov khoom siv hloov tshuab ua los ntawm cov haujlwm no hauv kev siv tswv yim yuav ua rau muaj txiaj ntsig zoo rau kev lag luam tsim khoom.

Daim ntawv thov tseem ceeb hauv kev hloov kho cov khoom siv yog melting kev kho mob, melting kev kho mob yog cov nto ntawm hlau cov ntaub ntawv nyob rau hauv lub laser beam irradiation rau hauv lub xeev melting, tib lub sij hawm sai sai solidified, ua ib tug tshiab nto txheej. Raws li lub microstructure ntawm cov khoom nto, nws tuaj yeem muab faib ua alloying, melting, remelting refining, glazing thiab nto compound, thiab lwm yam.
