Pfupiso Yakadzama yeMisoro yeKukwevera KweLaser Inobhururuka

Pfupiso Yakadzama yeMisoro yeWelding yeFlying Laser

Inofukidza mazita ezvikamu, tsananguro, misimboti, magadzirirwo ezvimiro uye kuverenga fomura, uye inoshanda kunewelding yekuskena nekukurumidza(senge masisitimu e galvanometer) kana mashandisirwo ekuwelda ari kure.

1. Kuumbwa uye Tsananguro yeMisoro yeWelding yeLaser Welding inobhururuka

Kukwesha kwemhepo kunobhururuka (Scanning Laser Welding) kunoita kuti pave nekukasira kunotarisa kuburikidza nemagetsi anomhanyisa anoratidzira mwenje welaser, uye kwakakodzera nzvimbo hombe nekushongedza nekumhanya kukuruZvikamu zvayo zvikuru ndeizvi:

1. Module yeKubatanidza Beam

Collimator

Basa: Shandura laser yakatsauka (NA=0.1~0.22) inobuda nefiber ye optical kuita danda rakafanana.

Maparamita akakosha: Focal length fcoll, collimated beam dhayamita Dcoll.

Fomura:

1.2 Sisitimu Yekuongorora yeGalvanometer

Magirazi eGalvo eX/Y-axis

Basa: Chinja divi remwenje wechiedza kuburikidza nemagirazi anotenderera anomhanya zvakanyanya kuti uwane scan yendege ine mativi maviri.

Maparamita akakosha: Kumhanya kwekuskena (kazhinji ≥10m/s), kudzokorora kurongeka kwenzvimbo (<±5μrad), saizi yegirazi (inoda kufukidza dhayamita yedanda Dcoll).

Mota yeGalvanometer: Mota yeServo kana galvanometer ine nguva yekupindura ye <1ms.

1.3 Dynamic Focusing Module (F-Theta Lens kana Galvanometer + Flat-Field Lens)

Lenzi yeF-Theta

Basa: Chinja kona yekutsauka kwe galvanometer kuita displacement yakatsetseka mundege kuti urambe wakatarisa zvakanaka.

Mafomura makuru:

2. Nheyo yekushanda

Nzira yedanda: Laser → Collimator → X galvanometer → Y galvanometer → F-Theta lenzi → Nzvimbo yebasa.

Kutarisa zvine simba:

Kana kona yekutsauka kwe galvanometer iri θ, nzvimbo yekutarisa (x, y) inoshandurwa ne lenzi yeF-Theta se:

3. Magadzirirwo Akakosha uye Mafomula

3.1 Kuverenga Saizi yeMavara

Dhayamita yenzvimbo yakatarisana d (muganhu wekupararira):

3.2 Kuyera Kureba uye Angle yeGalvanometer

Nzvimbo yepamusoro yekuskena L:

3.3 Kumhanya Kwekushongedza Uye Kukurumidzisa

Kumhanya kwemutsetse v

3.4 Kudzika Kwekutarisa (DOF)

3.5 Kuwanda kweMagetsi uye Kupinda Kwesimba

Kuwanda kwesimba I:

Kuwanda kwesimba E (kupinza kwepulse):

4. Kusanzwisisana uye Kugadzira Kugadzirisa

4.1 Kugadziriswa kweF-Theta Lens

Kukanganiswa: Inofanirwa kugutsa r∝θ, uye kukanganiswa kusiri kwemutsara kunofanirwa kuva <0.1%.

Kukombama kwemunda: Gadzira munda wakati sandara kuburikidza nemapoka ane malenzi akawanda.

4.2 Chikanganiso cheKubatanidza Galvanometer

Kunonoka kwe X/Y galvanometer kunofanira kuva <1μs kudzivirira mavara e elliptical.

5. Muenzaniso weMaitiro Ekugadzira

Zvinodiwa pakuisa zvinhu: Kureba kweskani L, saizi yenzvimbo d, kumhanya kwewelding v. Sarudza lenzi yeF-Theta: Sarudza fθ zvichienderana neL=2fθtan(θmax).

Verenga ma parameter e galvanometer: Angular velocity ω=v/fθ, uye simbisa mashandiro e galvanometer.

Simbisa hunhu hwenzvimbo: Gadzirisa kusawirirana kwemapoka emalenzi kuburikidza neZemax/OpticStudio.

6. Kungwarira

Kutarisira kupisa: MaGalvanometer nemalenzi anoda kutonhodzwa nemvura nesimba guru (senge >1kW).

Dziviriro yekudzivirira kuputika: MaGalvanometer anoda mabhureki ekukurumidza kudzivirira kudonha kwemotokari.

Kugadzirisa: Gara uchigadzirisa nzira ye optical coaxiality (kutsauka <0.05mm).
