Laser laser tshuab ntaus tshuab maj mam mus rau tib neeg lub neej txhua hnub, xws li xov tooj rov qab plhaw qauv, lub teeb hloov, lub tsheb hauv kev tswj ntawm cov yas tuav, tus font (qauv) ua tau laser laser tshuab txav mus cuag. Laser laser engraving qauv, tus processor feem ntau ntsib ib qho lus nug: "Vim laser engraving cov nyhuv yuav tsis ncaj ncees?"
Cov nyhuv ntawm uneven phenomenon tej zaum yuav muaj cov nram qab no vim li cas:
Cov theem ntawm lub tshuab tsis yog kho zoo, xws li, lub vibration lens los yog lub lens field yog tsis parallel rau lub rooj ua haujlwm;
Vim tias lawv tsis yog horizontal, yuav ua rau lub teeb ntawm lub lens los ntawm qhov chaw lens kom mus txog qhov ntev ntawm kev ua haujlwm ntawm qhov ntev ntawm qhov kev tsis sib haum xeeb, qhov kawg laser poob rau ntawm qhov khoom ua haujlwm muaj peev xwm yuav muaj qhov tsis sib xws zog, ces cov khoom yuav qhia cov nyhuv Inhomogeneous.
Laser cov zis yog blocked, uas yog, txoj kab teeb ci laser los ntawm galvanometer thiab daim teb lens flare tsis muaj txaus txaus;
Laser lub taub hau, fixtures thiab galvanometer thiab thiaj tsis qhib zoo, uas ua rau lub lens ntawm lub lens thaum ib feem ntawm qhov chaw ntawm lub teeb uas thaiv los ntawm qhov chaw lens ntawm cov zaus qhov multiplier phaj nws pib qhov chaw tsis yog, qhov no tseem yuav ua rau rau cov nyhuv ntawm tsis tusyees.
Muaj kuj yog ib qho teeb meem ntawm qhov teeb meem ntawm galvanometer lens kev puas tsuaj, thaum lub teeb meem ntawm laser los ntawm qhov kev puas tsuaj ntawm lub lens, tsis tuaj yeem pom zoo. Yog li no, lub nqaj laser tsis zoo sib xws nrog lub zog laser nyob hauv thaj tsam kev puas tsuaj ntawm qhov kev lens thiab thaj chaw uas tsis yog khoom ntawm lub lens, thiab lub zog laser lub zog ntawm cov khoom tsis zoo li qub, yog li ntawd cov cim nyhuv tsis yog yam tsis tau.
Siv qhov kev tsom xam ib nrab ntawm ib qho ntawm cov ntsiab lus;
Vim hais tias txhua qhov lens (thaj tsom iav) muaj qhov sib txawv ntawm kev ua kom pom tseeb, thiab kev siv ntawm txoj kev ua kom pom tseeb yuav yooj yim ua rau ntau hom kev cim, qhov chaw ntawm qhov taw tes ntawm lossis qhov tob tshaj ntawm qhov focal qhov ntsej muag ntau, yog li nws yog yooj yim Cause cov nyhuv ntawm non-uniformity. Yog li, txoj kev ntawm kev xaiv tus cim yuav tsum xav txog qhov teeb meem ntawm laser lub zog.
Thermal lens phenomenon;
Thaum lub laser los ntawm optical lens (refraction, reflection), lub lens tshav kub yuav ua rau cov hloov tshiab deformation. Qhov deformation no yuav ua rau lub teeb meem laser tsom mus, luv focal ntev. Yog hais tias lub tshuab tsau, thaum qhov kev teeb tsa raug kho rau qhov taw tes, qhov laser zog ceev ntawm cov khoom hloov vim yog thermal lens phenomenon tom qab laser muab rau ib lub sijhawm, yog li ntawd cov cim nyhuv tsis yog uniform. (Ntawm lub thermal lens phenomenon, xa rau yav dhau los hauv tsab xov xwm WeChat tsab xov xwm).
Qhov laj thawj ntawm cov khoom, xws li inconsistencies hauv zaj duab xis thickness ntawm cov khoom nto lossis hloov hauv cov khoom siv physicochemical;
Khoom siv yog ntau dua rau lub zog laser hluav taws xob. Feem ntau hauv cov khoom qub, lub zog laser nce mus txog qhov khoom puas tus nqi yog qhov tseeb. Thaum cov txheej txheem txheej thickness txawv, los yog muaj qee qhov lwm cov khoom siv lub cev thiab tshuaj kho tsis zoo li qub, tib yam yuav ua rau tsis muaj teebmeem laser marking effect.
