Sawir-qaade Laser, oo sidoo kale loo yaqaanno galvanometer laser, wuxuu ka kooban yahay madaxa iskaanka indhaha ee XY, cod-weyneeye wadida elegtarooniga ah iyo lenska milicsiga indhaha. Digniinta uu bixiyo kombuyuutarku waxa uu madaxa iskaanka indhaha ku wadaa wareegga cod-weyneeye wadista, si uu u xakameeyo leexinta laydhka laysarka ee diyaaradda XY. Si fudud marka loo hadlo, galvanometer-ku waa galvanometer iskaan ah oo loo isticmaalo warshadaha laysarka. Eraygeeda xirfadeed waxaa loogu yeeraa galvanometer iskaanka xawaaraha sare leh nidaamka iskaanka Galvo. Waxa loogu yeero galvanometer sidoo kale waxaa lagu magacaabi karaa ammeter. Fikraddeeda naqshadeynta waxay si buuxda u raacdaa habka naqshadeynta ammeter-ka. Muraayada ayaa bedelaya irbadda, calaamada baaritaanka waxaa lagu bedelayaa calaamad kombuyuutar lagu hago -5V-5V ama -10V-+10V DC. , si loo dhamaystiro ficilkii hore loo go'aamiyay. Sida nidaamka iskaanka muraayadda wareega, nidaamkan kantaroolka caadiga ah wuxuu isticmaalaa muraayadaha dib u soo celinta. Farqiga u dhexeeya ayaa ah in matoorka stepper-ka ee wada muraayadahaan muraayadaha ah waxaa lagu bedelay matoorka servo. Nidaamkan kantaroolka ah, dareemaha booska ayaa loo isticmaalaa Fikradda naqshadeynta iyo wareegga jawaab-celinta taban waxay sii hubinaysaa saxnaanta nidaamka, iyo xawaaraha iskaanka iyo saxnaanta meelaynta soo noqnoqda ee nidaamka oo dhan waxay gaaraan heer cusub. Madaxa calaamadaynta sawirka galvanometer wuxuu inta badan ka kooban yahay muraayada iskaanka ee XY, lens field, galvanometer iyo software-ka-kormeerka kumbuyuutarka. Dooro qaybaha indhaha ee u dhigma iyadoo loo eegayo hirarka dhererka laysarka ee kala duwan. Doorashooyinka la xidhiidha waxa kale oo ka mid ah balaadhinta laydhka laysarka, leysarka, iwm. Nidaamka bandhiga laysarka, qaabka mowjadda sawirka indhaha waa sawir-qaadis, iyo xawaaraha iskaanka ee nidaamka ayaa go'aaminaya xasilloonida qaabka laysarka. Sannadihii u dambeeyay, sawir-qaadayaal xawaare sare leh ayaa la sameeyay, iyadoo xawaarahoodu gaadhay 45,000 dhibcood / ilbiriqsi, taasoo suurtogal ka dhigaysa in la muujiyo animations laser adag.
5.1 Laser galvanometer alxanka wadajirka ah
5.1.1 Qeexida iyo ka kooban yahay alxanka galvanometer:
Madaxa diiradda saaraya isku-dhafka wuxuu isticmaalaa qalab makaanik ah sidii madal taageero ah. Qalabka farsamaysan ayaa hore iyo gadaal u dhaqaaqa si uu u gaaro alxanka alxanka kala duwan. Saxnaanta alxanka waxay kuxirantahay saxnaanta jileeyaha, sidaa darteed waxaa jira dhibaatooyin sida saxnaanta hoose, xawaaraha jawaab celinta oo gaabis ah, iyo firfircooni la'aan weyn. Nidaamka iskaanka galvanometer wuxuu isticmaalaa mato si uu u qaado muraayada leexashada. Matoorka waxaa wata wax hadda jira oo leh faa'iidooyinka saxnaanta sare, firfircoonida yar, iyo jawaab celinta degdega ah. Marka laydhka lagu iftiimiyo muraayada galvanometer, leexashada galvanometerku waxay beddeshaa laydhka laysarka. Sidaa darteed, laydhka laysarka wuxuu baari karaa raad kasta oo ku yaal goobta sawirka ee muuqaalka iyada oo loo marayo nidaamka galvanometer.
Qaybaha ugu muhiimsan ee nidaamka iskaanka galvanometer-ka waa collimator balaarin beam, lens diirada saaraya, galvanometer scanning XY laba-dhidib, guddiga kontoroolka iyo nidaamka software computer martigeliyaha. Galvanometer-ka sawirku wuxuu inta badan tilmaamayaa labada madax ee iskaanka XY galvanometer, kuwaas oo ay wataan matoorada servo ee xawaaraha sare leh. Nidaamka servo dual-axis wuxuu wadaa galvanometer-ka dhidibka-dual-axis scanning galvanometer si uu u leexiyo dhidibka X iyo dhidibka Y- siday u kala horreeyaan isagoo u diraya calaamadaha amarka matoorada servo ee X iyo dhidibka Y. Sidan oo kale, iyada oo loo marayo dhaqdhaqaaqa isku dhafan ee muraayadda muraayadda labada dhidib ee XY, nidaamka xakamaynta wuxuu u rogi karaa calaamadda iyada oo loo marayo guddiga galvanometer sida ku cad template graphic preset ee software kombiyuutarka martida loo yahay iyadoo loo eegayo dariiqa loo dejiyay, oo si deg deg ah u dhaqaaqo diyaarad workpiece si ay u sameeyaan raad sawir.
5.1.2 Kala soocida kala-goysyada alxanka galvanometer:
1. Lensiga iskaanka ee diiradda saaraya hore
Marka loo eego xidhiidhka ka dhexeeya lens-fiirinta iyo galvanometer-ka laysarka, qaabka iskaanka galvanometer-ka waxa loo qaybin karaa iskaanka diirada saarida hore (Jaantuska 1 hoose) iyo sawiraynta diirada gadaale (Jaantuska 2 hoose). Sababtoo ah jiritaanka kala duwanaanshaha dariiqa indhaha marka laydhka laysarka loo leexiyo meelo kala duwan (masaafada gudbinta iftiinka waa ka duwan tahay), dusha sare ee laysarka inta lagu jiro habka hore ee diiradda saarista habka baaritaanka waa dusha sare ee hemispherical, sida ku cad shaxanka bidix. Habka iskaanka-fiirsashada ka dib waxa lagu muujiyay sawirka dhanka midig. Muraayada ujeedadu waa muraayad F-plan. Muraayada F-plan waxay leedahay nashqad muuqaal gaar ah. Soo bandhigida hagaajinta indhaha, dusha sare ee xudunta u ah laydhka laysarka ayaa lagu hagaajin karaa si siman. Sawirka-fiirinta ka dib waxay inta badan ku habboon tahay codsiyada u baahan saxnaanta hab-socodka sare iyo kala duwanaansho yar oo farsameyn ah, sida calaamadaynta laysarka, alxanka qaab-dhismeedka yar-yar ee laysarka, iwm.
2.Lensiska iskaanka ee diiradda saaraya gadaal
Marka aagga iskaanka uu kordho, daloolka lenska f-theta sidoo kale wuu kordhiyaa. Sababtoo ah xaddidaadaha farsamada iyo maadada, muraayadaha f-theta-ga weyn ayaa aad qaali u ah xalkan lama aqbalin. Nidaamka sawirka galvanometer lens-ka ee hore oo ay weheliso robot-ka lixda dhidibka ah waa xal macquul ah, kaas oo yarayn kara ku-tiirsanaanta qalabka galvanometer, oo leh heer aad u fiican oo sax ah nidaamka, oo leh iswaafajin wanaagsan. Xalkan waxa qaatay inta badan isku xidhayaasha. Qaado, oo inta badan loo yaqaan alxanka duulimaadka. Alxanka baska moduleka, oo ay ku jiraan nadiifinta tiirarka, ayaa leh codsiyada duulimaadka, kaas oo kordhin kara ballaca hab-socodka si dabacsan oo hufan.
3.3D galvanometer:
Iyada oo aan loo eegin haddii ay tahay iskaanka-saar hore u-fiirsasho ama iskaan-raadinta gadaal-u-fiirinta, diiradda laydhka laysarka laguma xakamayn karo diiradda firfircoonida leh. Habka iskaanka diiradda hore, marka workpiece in la baaraandegi waa yar yahay, lens diiradda leeyahay kala duwan qoto dheer focal gaar ah, si ay u samayn kartaa iskaanka diiradda leh qaab yar. Si kastaba ha noqotee, marka diyaaradda la sawirayo ay weyn tahay, dhibcaha u dhow hareeraha waxay noqon doonaan diiradda oo laguma saari karo dusha sare ee shaqada si loo farsameeyo sababtoo ah waxay ka badan tahay qiyaasta qoto dheer ee diiradda laysarka. Sidaa darteed, marka laydhka laysarka looga baahan yahay inuu si fiican u foojignaado meel kasta oo ka mid ah diyaaradda sawir-qaadista iyo goobta muuqaalku waa weyn yahay, isticmaalka muraayadda dhererka dhererka go'an ma buuxin karto shuruudaha iskaanka. Nidaamka diiradda saaraya firfircooni waa nidaamyo indho-indhayn oo dhererkoodu uu isbeddeli karo marka loo baahdo. Sidaa darteed, cilmi-baarayaashu waxay soo jeedinayaan isticmaalka lens diiradda saaraya firfircoon si loo magdhabo farqiga u dhexeeya waddada indhaha, oo ay isticmaalaan lens concave (ballaare beam) si ay si toos ah ugu socdaan dhidibka indhaha si loo xakameeyo booska diiradda loona gaaro dusha sare ee la farsameeyo si firfircooni ah ayaa magdhow u ah indhaha indhaha. farqiga wadada ee jagooyinka kala duwan. Marka la barbar dhigo galvanometer 2D ah, halabuurka galvanometer 3D inta badan wuxuu ku darayaa "nidaamka indhaha ee dhidibka Z-axis", si galvanometer 3D si xor ah u bedeli karaa booska diiradda inta lagu guda jiro habka alxanka iyo fulinta alxanka dusha qaloocan, iyada oo aan baahida loo qabo in la beddelo. sidaha sida qalabka mashiinka, iwm. sida galvanometer 2D ah. Dhererka robotka waxaa loo isticmaalaa in lagu hagaajiyo booska diiradda alxanka.
