Scaneri ya Laser, nanone yitwa laser galvanometer, igizwe na XY optique yo gusikana umutwe, ibyuma bya elegitoroniki byongera ibikoresho bya optique. Ikimenyetso gitangwa na mugenzuzi wa mudasobwa gitwara optique yo gusikana binyuze mumuzunguruko wa amplifier, bityo bikagenzura gutandukana kwa lazeri mu ndege ya XY. Muri make, galvanometero ni scanning galvanometero ikoreshwa mubikorwa bya laser. Ijambo ryumwuga ryitwa kwihuta cyane gusikana galvanometero ya sisitemu yo gusikana. Ibyo bita galvanometero birashobora kandi kwitwa ammeter. Igitekerezo cyacyo cyo gushushanya gikurikiza rwose uburyo bwo gushushanya ammeter. Lens isimbuza urushinge, kandi ibimenyetso bya probe bisimburwa na mudasobwa igenzurwa na -5V-5V cyangwa -10V- + 10V DC. , kugirango urangize ibikorwa byateganijwe mbere. Nka sisitemu yo kuzunguruka indorerwamo yogusuzuma, iyi sisitemu isanzwe igenzura ikoresha indorerwamo ikuramo. Itandukaniro nuko moteri yintambwe itwara iyi linzira isimburwa na moteri ya servo. Muri ubu buryo bwo kugenzura, icyuma gikoresha imyanya ikoreshwa Igishushanyo mbonera cya hamwe nibitekerezo bibi byatanzwe bikomeza kwemeza neza sisitemu, kandi umuvuduko wo gusikana hamwe nuburyo bugaragara bwa sisitemu yose igera kurwego rushya. Ikimenyetso cya galvanometero cyerekana umutwe kigizwe ahanini nindorerwamo ya XY yogusikana, lens ya field, galvanometero hamwe na software igenzurwa na mudasobwa. Hitamo ibice bya optique ukurikije uburebure bwa laser butandukanye. Amahitamo ajyanye nayo arimo kwagura laser beam, lazeri, nibindi. Muri sisitemu yo kwerekana laser, imiterere ya optique yo gusikana ni vector scan, kandi umuvuduko wo gusikana wa sisitemu ugena ituze ryuburyo bwa laser. Mu myaka yashize, hashyizweho scaneri yihuta cyane, hamwe nogusuzuma umuvuduko ugera kumanota 45,000 / isegonda, bigatuma bishoboka kwerekana animasiyo ya laser igoye.
5.1 Laser galvanometero yo gusudira hamwe
5.1.1 Ibisobanuro hamwe nibigize galvanometero yo gusudira hamwe:
Gukusanya kwibanda kumutwe ukoresha ibikoresho bya mashini nkurubuga rushyigikira. Igikoresho cya mashini kigenda gisubira inyuma kugirango kigere ku gusudira kwa trayektori zitandukanye. Ubudozi bwo gusudira buterwa nukuri kwimikorere, bityo haribibazo nkibisobanuro bike, umuvuduko wo gusubiza buhoro, hamwe nubusembure bunini. Sisitemu yo gusikana ya galvanometero ikoresha moteri yo gutwara lens yo gutandukana. Moteri itwarwa numuyoboro runaka kandi ifite ibyiza byo hejuru cyane, inertia nto, hamwe nigisubizo cyihuse. Iyo urumuri rumurikirwa kumurongo wa galvanometero, gutandukana kwa galvanometero bihindura urumuri rwa laser. Kubwibyo, urumuri rwa lazeri rushobora gusikana inzira iyo ari yo yose yo kubisikana binyuze muri sisitemu ya galvanometero.
Ibice byingenzi bigize sisitemu yo gusikana galvanometero ni kwagura ibiti, kwibanda kuri lens, XY ebyiri-axis scanning galvanometer, ikibaho cyo kugenzura hamwe na sisitemu ya mudasobwa. Gusikana galvanometero byerekeza cyane cyane kuri XY galvanometero ebyiri zo gusikana imitwe, itwarwa na moteri yihuta yo kwisubiraho. Sisitemu ya dual-axis ya servo itwara XY dual-axis yogusuzuma galvanometero kugirango ihindukire kuri X-axis na Y-axis ikohereza ibimenyetso byerekanwa kuri moteri ya X na Y-axis. Muri ubu buryo, binyuze mumigendekere ya XY ibiri-axis indorerwamo yindorerwamo, sisitemu yo kugenzura irashobora guhindura ibimenyetso ikoresheje ikibaho cya galvanometero ukurikije igishushanyo mbonera cyerekana igishushanyo mbonera cya software yakiriye ukurikije inzira yashyizweho, hanyuma igahita ikomeza kuri indege ikora kugirango ikore scanning trayectory.
5.1.2 Itondekanya rya galvanometero yo gusudira hamwe:
1. Imbere yibanda kumurongo
Ukurikije isano iri hagati yinteguza yibanze na laser galvanometero, uburyo bwo gusikana bwa galvanometero burashobora kugabanywamo ibice byerekanwa mbere (Ishusho 1 hepfo) hamwe ninyuma yibanda kuri scanne (Ishusho 2 hepfo). Bitewe no kubaho gutandukanya inzira ya optique mugihe urumuri rwa lazeri rwerekejwe mumyanya itandukanye (intera yohereza urumuri rutandukanye), hejuru ya laser yibanze mugihe cyambere cyo kwibandaho uburyo bwo gusikana ni ubuso bwisi, nkuko bigaragara mumashusho yibumoso. Uburyo bwibanze bwo gusikana bwerekanwe kumashusho iburyo. Intego yintego ni lens ya F-plan. Indorerwamo ya F- ifite igishushanyo cyihariye cya optique. Mugutangiza ubugororangingo bwa optique, igice cyo hejuru cyibice bya lazeri birashobora guhindurwa neza. Gusikana nyuma yibyingenzi birakwiriye cyane cyane kubisabwa bisaba gutunganywa neza hamwe no gutunganya ibintu bito, nka marike ya laser, microstructure yo gusudira, nibindi.
2.Inyuma yibanda kumurongo
Mugihe agace ka scaneri kiyongera, aperture ya lens ya f-theta nayo iriyongera. Bitewe na tekinike nibikoresho bifatika, lens nini-fert ya f-theta ihenze cyane kandi iki gisubizo nticyemewe. Intego ya lens imbere ya sisitemu yo gusikana ya galvanometero ihujwe na robot itandatu-axis nigisubizo gishoboka, gishobora kugabanya gushingira kubikoresho bya galvanometero, bifite urwego rutari ruto rwa sisitemu, kandi bifite aho bihurira. Iki gisubizo cyakiriwe nabenshi mubahuza. Kwemera, bakunze kwita gusudira indege. Kuzenguruka module busbar, harimo gusukura inkingi, ifite porogaramu zo kuguruka, zishobora kongera ubugari bwo gutunganya byoroshye kandi neza.
3.3D galvanometero:
Hatitawe ku kuba ari icyerekezo cyerekanwe imbere cyangwa gusikana inyuma, icyerekezo cya lazeri ntigishobora kugenzurwa no kwibanda ku mbaraga. Kuburyo bwibanze bwo gusikana, mugihe igikorwa cyo gutunganyirizwa ari gito, lens yibanze ifite intera ndende yimbitse, kuburyo ishobora gukora scanne yibanze hamwe nuburyo buto. Ariko, mugihe indege igomba gusikanwa ari nini, ingingo zegereye impande zose ntizishobora kwibandwaho kandi ntizishobora kwibanda hejuru yumurimo wakazi ugomba gutunganywa kuko urenze uburebure bwimbitse bwa laser. Kubwibyo, mugihe urumuri rwa lazeri rusabwa kwibanda neza kumwanya uwo ariwo wose uri mu ndege ya scaneri kandi umurima wo kureba ni munini, ikoreshwa ryinzira ndende ntishobora guhuza ibisabwa. Sisitemu yibanze yibanze ni sisitemu ya optique ifite uburebure bwibanze bushobora guhinduka nkuko bikenewe. Kubwibyo, abashakashatsi batanga igitekerezo cyo gukoresha lensike yibanda kumurongo kugirango bishyure itandukaniro ryinzira nziza, kandi bagakoresha lens ya conge (beam expander) kugirango bagendere kumurongo ugana umurongo wa optique kugirango bagenzure icyerekezo cyibanze kandi bagere kubuso butunganyirizwa muburyo bwo kwishyura optique. itandukaniro ryinzira kumyanya itandukanye. Ugereranije na 2D galvanometero, ibice bya 3D galvanometero byongeweho cyane cyane "Z-axis optique sisitemu", kugirango galvanometero ya 3D ishobore guhindura kubuntu umwanya wibanze mugihe cyo gusudira no gukora ubuso bugoramye busa, bitabaye ngombwa ko bihinduka umwikorezi nkigikoresho cyimashini, nibindi nka 2D galvanometero. Uburebure bwa robo bukoreshwa muguhindura umwanya wo gusudira.
