Incamake irambuye yaImitwe yo gusudira hakoreshejwe laser iguruka

Ikubiyemo amazina y'ibice, ibisobanuro, amahame, ibipimo by'igishushanyo n'ibarura rya formula, kandi ikoreshwa kurigusudira hifashishijwe uburyo bwo gupima vuba(nk'uburyo bwa galvanometer) cyangwa gukoresha ubusuguti bwa kure.

1. Imiterere n'ibisobanuro by'imitwe yo gusudira hakoreshejwe laser

Gusudira mu kirere (Scanning Laser Welding) bikoresha ikoranabuhanga rigezweho rikoresha galvanometer yihuta cyane igaragaza imirasire ya laser, kandi rikwiriye ahantu hanini no mugusudira vuba cyaneIbice by'ingenzi byayo ni ibi bikurikira:

1. Module yo guhuza imirasire

Collimator

Imikorere: Hindura umuvuduko wa laser itandukanya (NA = 0.1 ~ 0.22) unyuze kuri fibre optique mo urumuri ruhurirana.

Ibipimo by'ingenzi: Uburebure bw'ifatizo fcoll, umurambararo w'umuraba wa collimated Dcoll.

Ifishi y'ifishi:

1.2 Sisitemu yo Gupima Galvanometer

Indorerwamo za Galvo za X/Y-axis

Imikorere: Hindura icyerekezo cy'urumuri unyuze mu ndorerwamo zizenguruka vuba cyane kugira ngo ugere ku gusesengura ikirere mu buryo bw'ibice bibiri.

Ibipimo by'ingenzi: Umuvuduko wo gushakisha (ubusanzwe ni ≥10m/s), uburyo bwo gusubiramo neza aho uherereye (<±5μrad), ingano y'indorerwamo (igomba gupfuka umurambararo wa Dcoll).

Moteri ya Galvanometer: Moteri ya Servo cyangwa moteri ya galvanometer ifite igihe cyo gusubiza cya <1ms.

1.3 Itsinda ry'ibyitegererezo bihindagurika (Lens ya F-Theta cyangwa Galvanometer + Lens ya Flat-Field)

Ikirahuri cya F-Theta

Imikorere: Hindura inguni yo kuzenguruka ya galvanometer mo inzira igororotse mu ndege kugira ngo ukomeze gushimangira imiterere yayo.

Amabwiriza y'ingenzi:

2. Ihame ry'imikorere

Inzira y'umuraba: Laser → Collimator → X galvanometer → Y galvanometer → F-Theta lens → Ubuso bw'imashini.

Kwibanda ku buryo buhamye:

Iyo inguni ya galvanometer deflection ari θ, aho umurongo w'icyerekezo (x, y) uhindurwa na lens ya F-Theta nka:

3. Ibipimo by'ingenzi by'igishushanyo mbonera n'amafilimi

3.1 Ibarura ry'ingano y'ahantu

Umurambararo w'ahantu hibanzweho d (umupaka w'impinduka):

3.2 Ingano yo Gusuzuma n'Inguni ya Galvanometer

Intera ntarengwa yo gushakisha L:

3.3 Umuvuduko wo gusudira no kwihuta

Umuvuduko w'umurongo v

3.4 Ubujyakuzimu bw'Icyerekezo (DOF)

3.5 Ubucucike bw'ingufu n'ingufu zikoreshwa

Ubucucike bw'ingufu I:

Ubucucike bw'ingufu E (gusudira imitsi):

4. Guhindura imiterere no kunoza imiterere

4.1 Gukosora ikosa rya F-Theta Lens

Kugoreka: Bigomba kuba byujuje r∝θ, kandi kugoreka kutari kumurongo bigomba kuba <0.1%.

Guhindura imiterere y'ikibuga: Kora igishushanyo cy'ikibuga giteye nk'ikirambuye ukoresheje amatsinda y'ama-lens menshi.

4.2 Ikosa ryo guhuza Galvanometer

Gutinda kwa galvanometer ya X/Y bigomba kuba <1μs kugira ngo hirindwe ahantu hameze nk'urukiramende.

5. Urugero rw'Inzira yo Gushushanya

Ibisabwa mu gupima: Intera yo gupima L, ingano y'agace d, umuvuduko wo gusudira v. Hitamo lenzi ya F-Theta: Menya fθ ukurikije L=2fθtan(θmax).

Kubara ibipimo bya galvanometer: Umuvuduko wa angular ω=v/fθ, hanyuma urebe imikorere ya galvanometer.

Genzura ubuziranenge bw'ahantu: Ongera uburyo amatsinda y'indorerwamo ya lens ahinduka ukoresheje Zemax / OpticStudio.

6. Amabwiriza yo kwirinda

Gucunga ubushyuhe: Galvanometers na lenses bikenera gukonjesha amazi hakoreshejwe imbaraga nyinshi (nk'ingufu >1kW).

Uburinzi ku impanuka: Galvanometers zikenera feri yihutirwa kugira ngo hirindwe kugongana na mashini.

Gupima: Gupima buri gihe uburyo bwo guhuza inzira y'urumuri (ihindagurika <0.05mm).
