Laser drilling yog laser ua tshuab uas xuas nrig ntaus lub qhov los ntawm lub tshuab hluav taws xob hluav taws xob nrog lub zog siab ceev thiab nyob luv luv (qis dua laser txiav). Aperture tsim tuaj yeem ua tiav los ntawm ib qho pulse lossis ntau lub pulses.
Hauv cov txheej txheem xuas nrig ntaus, thawj zaug siv lub tshuab xuas nrig ntaus los npaj cov qhov me me ntawm qhov loj txaus, kom cov txheej txheem txiav tom ntej pib los ntawm no. Cov txheej txheem drilling los yog nkag mus yuav tsum tau rov ua dua lub tshuab hluav taws xob laser nrog lub siab ncov lub zog, thiab tib lub sijhawm, nws pom tau tias muaj huab cua siab. Tom qab lub workpiece yog nkag mus, lub laser beam txiav los ntawm kev txo lub ncov lub hwj chim los yog txawm hloov mus rau ib tug pulseless hom.
Solid-state lasers muaj luv wavelengths thiab muaj peev xwm ua tau siab-siv mem tes tso zis, yog li lawv tsim nyog rau laser drilling, xws li Nd: YAG lasers, Nd: iav lasers thiab Nd: ruby lasers.
CO2 lasers feem ntau yog siv los qhib qhov pores hauv cov ntaub ntawv tsis yog xim hlau xws li ceramics, composites, plastics lossis roj hmab. Laser drilling ntawm hlau cov ntaub ntawv yuav tsum tau ib tug mem tes laser, thiab lub beam tsom lub zog ceev yuav tsum siab tshaj 10^5 W / mm^2 (6.5 W / in.^2 × 10^7 W / in.^2).
Kev tsom xam ntawm lub teeb laser.
Nyob rau hauv laser drilling hom, ib tug luv luv focal ntev lens yuav tsum tau tsom mus rau lub siab ncov lub hwj chim beam ntawm lub pulsed laser mus rau ib qho chaw ntawm qhov kev txiav txim ntawm 0.6 mm nyob rau hauv txoj kab uas hla mus cuag lub hwj chim density theem yuav tsum tau rau drilling.
Tsawg divergence ntawm lub laser beam tuaj yeem ua tiav los ntawm cov laser resonators tshwj xeeb. Lub beam txoj kab uas hla tuaj yeem tswj tau los ntawm kev hloov lub aperture ntawm cov cuab yeej tsom. Yog li ntawd, lub aperture yuav siv tau los ua kom lub zog ceev ntawm lub teeb tsom teeb pom kev zoo thiab txhim kho kev siv zog ntawm cov nqaj.
Qhov zoo ntawm laser drilling tshuab
Laser drilling muaj feem ntau ntawm qhov zoo ntawm laser txiav. Nws tsuas yog yuav tsum tau ua kom cov nqaj thiab qhov saum npoo ntawm cov khoom tsim ib lub kaum ntse ntse kom paub txog kev noj thiab xuas nrig ntaus ntawm lub laser beam, uas zoo zam qhov tshwm sim ntawm kev cuam tshuam thiab fragmentation tshwm sim los ntawm cov txheej txheem cuam tshuam thaum lub sij hawm ua tshuab.
Lwm qhov zoo ntawm laser drilling
1. Lub sijhawm qhib luv luv
2. Muaj zog automation adaptability
3. tuaj yeem siv rau kev nkag mus rau kev ua haujlwm ntawm cov ntaub ntawv nyuaj qhib
4. Piv nrog rau cov neeg kho tshuab qhib, tsis muaj cov neeg kho tshuab hnav hauv txhua daim ntawv ntawm cov txheej txheem qhib thiab cov khoom ua haujlwm.
Laser drilling yog qhov ua tau zoo tshaj plaws ntawm kev siv tshuab laser, thiab nws kuj yog ib qho ntawm cov ntawv thov tseem ceeb ntawm kev ua laser. Laser drilling yog tsuas yog siv rau hlau cov ntaub ntawv hlau, platinum, molybdenum, tantalum, magnesium, germanium, silicon, lub teeb hlau cov ntaub ntawv tooj liab, zinc, aluminium, stainless hlau, tshav kub-resistant alloys, npib tsib xee matrix alloys, titanium kub, platinum, ntau carbide. Cov khoom siv hlau nplaum thiab cov khoom siv ceramic, cov pob zeb cuav, pob zeb diamond films, ceramics, roj hmab, yas, iav, thiab lwm yam hauv cov ntaub ntawv tsis yog xim hlau.
