Isishwankathelo esineenkcukacha zeIintloko zokuWelda zeLaser ezibhabhayo

Igubungela amagama eenxalenye, iinkcazo, imigaqo, iiparameter zoyilo kunye nokubalwa kwefomula, kwaye iyasebenza kwiukuwelda kokuskena okukhawulezayo(ezifana neenkqubo ze-galvanometer) okanye izicelo zokuwelda ezikude.

1. Ukwakhiwa kunye neNkcazelo yeeNtloko zokuWelda zeLaser zokuWelda ezibhabhayo

Ukuwelda okubhabhayo (Ukuwelda ngeLaser yokuSkena) kufezekisa ukugxila okunamandla nge-galvanometer ekhawulezayo ebonisa imisebe yelaser, kwaye ifanelekile kwiindawo ezinkulu nakwimimandla.ukuwelda ngesantya esiphezuluIzinto eziphambili zayo zezi zilandelayo:

1. Imodyuli yokuhlanganisa imisebe

I-Collimator

Umsebenzi: Guqula i-divergent laser output (NA=0.1~0.22) yi-optical fiber ibe yi-parallel beam.

Iiparameter eziphambili: Ubude be-focal fcoll, ububanzi be-collimated beam Dcoll.

Ifomula:

1.2 Inkqubo yokuSkena iGalvanometer

Izibuko zeGalvo ze-X/Y-axis

Umsebenzi: Tshintsha indlela yokukhanya ngokusebenzisa izipili ezijikelezayo ngesantya esiphezulu ukuze ufezekise ukuskena kwendiza okunemilinganiselo emibini.

Iiparameter eziphambili: Isantya sokuskena (ngesiqhelo yi-≥10m/s), ukuchaneka kokubeka kwakhona (<±5μrad), ubungakanani besipili (kufuneka sigqume ububanzi bemitha ye-Dcoll).

Imoto yeGalvanometer: Imoto yeServo okanye imota yegalvanometer enexesha lokuphendula elingaphantsi kwe-1ms.

1.3 Imodyuli yoQokelelo oluDynamic (Ilensi ye-F-Theta okanye iGalvanometer + Ilensi yeFlat-Field)

Ilensi ye-F-Theta

Umsebenzi: Guqula i-engile yokuphambuka kwe-galvanometer ibe yindlela ethe tye yokuhamba kwindiza ukuze kugcinwe ukuhambelana kokugxila.

Iifomula eziphambili:

2. Umgaqo Wokusebenza

Indlela yemitha: I-Laser → I-Collimator → I-X galvanometer → I-Y galvanometer → Ilensi ye-F-Theta → Umphezulu wesixhobo sokusebenzela.

Ukugxila okunamandla:

Xa i-angle yokuphambuka kwe-galvanometer ingu-θ, indawo yokugxila (x, y) iguqulwa yilensi ye-F-Theta njenge:

3. IiParamitha zoYilo oluPhambili kunye neeFomula

3.1 Ukubalwa kobungakanani beendawo

Ububanzi bendawo egxile ku-d (umda wokwahluka):

3.2 Uluhlu lokuSkena kunye ne-Galvanometer Angle

Uluhlu oluphezulu lokuskena L:

3.3 Isantya sokuWelda kunye nokuKhawulezisa

Isantya esithe ngqo v

3.4 Ubunzulu boGxilo (DOF)

3.5 Ubuninzi bamandla kunye nokufakwa kwamandla

Uxinano lwamandla I:

Uxinano lwamandla E (ukuwelda kwepulse):

4. Uyilo lweempazamo kunye noLungiso

4.1 Ukulungiswa kokuphazamiseka kweLensi ye-F-Theta

Ukuguqulwa: Kufuneka yanelise u-r∝θ, kwaye ukuguqulwa okungekho ngqo kufuneka kube <0.1%.

Ukugoba kwentsimi: Yila intsimi ethe tyaba ngamaqela eelensi ezininzi.

4.2 Impazamo yokuvumelanisa iGalvanometer

Ukulibaziseka kwe-X/Y galvanometer kufuneka kube <1μs ukuze kuthintelwe amabala e-elliptical.

5. Umzekelo weNkqubo yoYilo

Iimfuno zokufaka: Uluhlu lokuskena L, ubungakanani bebala d, isantya sokuwelda v. Khetha ilensi ye-F-Theta: Misela i-fθ ngokwe-L=2fθtan(θmax).

Bala iiparameter ze-galvanometer: Isantya se-angular ω=v/fθ, kwaye uqinisekise ukusebenza kwe-galvanometer.

Qinisekisa umgangatho wendawo: Lungiselela ukuguquguquka kweqela leelensi ngeZemax/OpticStudio.

6. Amanyathelo okuzikhusela

Ulawulo lobushushu: IiGalvanometers kunye neelensi zifuna ukupholisa amanzi phantsi kwamandla aphezulu (afana ne->1kW).

Ukhuseleko lokungangqubani: IiGalvanometer zifuna ukubhuleka okungxamisekileyo ukuze zingangqubani ngoomatshini.

Ukulinganisa: Lungisa rhoqo indlela ye-optical coaxiality (ukuphambuka <0.05mm).
