Isithwebuli se-laser, esibizwa nangokuthi i-laser galvanometer, sinekhanda lokuskena le-XY, isikhulisi se-electronic drive kanye ne-optical reflection lens. Isignali ehlinzekwe yisilawuli sekhompuyutha ishayela ikhanda lokuskena le-optical ngokusebenzisa isekethe ye-amplifier yokushayela, ngaleyo ndlela ilawula ukuchezuka kwe-laser beam endizeni ye-XY. Ukukhuluma nje, i-galvanometer iyi-galvanometer yokuskena esetshenziswa embonini ye-laser. Igama layo lochwepheshe libizwa nge-high-speed scanning galvanometer Galvo uhlelo lokuskena. I-galvanometer ebizwa nangokuthi i-ammeter. Umbono wayo wokuklama ulandela ngokuphelele indlela yokuklama ye-ammeter. Ilensi ithatha indawo yenaliti, futhi isignali ye-probe ithathelwa indawo isignali elawulwa ngekhompuyutha -5V-5V noma -10V-+10V DC. , ukuqedela isenzo esinqunywe kusengaphambili. Njengesistimu yokuskena kwesibuko esizungezayo, le sistimu yokulawula evamile isebenzisa ipheya yezibuko ezihlehlisayo. Umehluko wukuthi i-stepper motor eshayela le sethi yamalensi ithathelwa indawo yi-servo motor. Kulolu hlelo lokulawula, kusetshenziswa inzwa yokuma Umbono wokuklama kanye nelophu yempendulo engalungile uqinisekisa futhi ukunemba kwesistimu, futhi isivinini sokuskena nokunemba kokuma okuphindaphindiwe kwalo lonke uhlelo kufinyelela ezingeni elisha. Ikhanda lokumaka lokuskena i-galvanometer lakhiwe ikakhulukazi isibuko sokuskena se-XY, ilensi yenkundla, i-galvanometer kanye nesofthiwe yokumaka elawulwa ngekhompuyutha. Khetha izingxenye ze-optical ezihambisanayo ngokuya ngamaza ahlukene e-laser. Izinketho ezihlobene futhi zihlanganisa izinwebe ze-laser beam, ama-laser, njll. Kuhlelo lokuboniswa kwe-laser, i-waveform ye-optical scanning i-vector scan, futhi isivinini sokuskena sohlelo sinquma ukuzinza kwephethini ye-laser. Eminyakeni yamuva nje, kuye kwathuthukiswa izikena ezinesivinini esikhulu, ezinesivinini sokuskena esifinyelela kumaphuzu angu-45,000/ngesekhondi, okwenza kube nokwenzeka ukukhombisa izithombe ze-laser eziyinkimbinkimbi.
5.1 Laser galvanometer welding joint
5.1.1 Incazelo kanye nokwakheka kwejoyinti yokushisela ye-galvanometer:
Ikhanda eligxile ekungqubuzaneni lisebenzisa idivayisi engumshini njengengxenyekazi esekelayo. Idivaysi ewumshini iya phambili naphambili ukuze kuzuzwe ukushiselwa kwamashisela ahlukene e-trajectory. Ukunemba kwe-welding kuncike ekunembeni kwe-actuator, ngakho-ke kunezinkinga ezifana nokunemba okuphansi, isivinini sokuphendula esinensayo, kanye ne-inetia enkulu. Isistimu yokuskena ye-galvanometer isebenzisa injini ukuphatha ilensi ukuze iphambuke. Injini ishayelwa i-current ethile futhi inezinzuzo zokunemba okuphezulu, inertia encane, nokuphendula okusheshayo. Lapho ugongolo lukhanyiswa ilensi ye-galvanometer, ukuchezuka kwe-galvanometer kushintsha i-laser beam. Ngakho-ke, i-laser beam ingaskena noma iyiphi i-trajectory emkhakheni wokuskena wokubuka ngohlelo lwe-galvanometer.
Izingxenye eziyinhloko zesistimu yokuskena ye-galvanometer i-collimator yokwandisa ugongolo, i-lens egxile, i-galvanometer yokuskena ye-XY yama-axis amabili, ibhodi lokulawula kanye nesistimu yesofthiwe yekhompyutha yokusingatha. I-galvanometer yokuskena ibhekisela ikakhulukazi emakhanda amabili okuskena e-XY galvanometer, aqhutshwa ama-servo motors anesivinini esikhulu. Isistimu ye-servo ye-dual-axis ishayela i-galvanometer ye-XY dual-axis scanning ukuze iphambukise ku-X-eksisi kanye ne-Y-eksisi ngokulandelana ngokuthumela amasiginali womyalo kuma-motor X kanye ne-Y-axis servo. Ngale ndlela, ngokunyakaza okuhlangene kwe-XY-axis mirror lens, uhlelo lokulawula lungakwazi ukuguqula isignali ngebhodi le-galvanometer ngokusho kwesifanekiso esisethiwe se-software yekhompiyutha ephethe ngokulandela indlela emisiwe, futhi ngokushesha siqhubekele phambili indiza ye-workpiece ukwakha umzila wokuskena.
5.1.2 Ukuhlelwa kwamajoyinti okushisela ama-galvanometer:
1. Ilensi yokuskena egxile ngaphambili
Ngokobudlelwano bendawo phakathi kwelensi egxilile ne-laser galvanometer, imodi yokuskena ye-galvanometer ingahlukaniswa ibe ukuskena okugxilwe ngaphambili (Umfanekiso 1 ngezansi) kanye nokugxila okugxile kokuskena kwangemuva (Umfanekiso 2 ngezansi). Ngenxa yokuba khona komehluko wendlela yokubona lapho i-laser beam iphambukiselwa ezindaweni ezihlukene (ibanga lokudluliswa kwe-beam lihlukile), indawo egxile kwi-laser phakathi nenqubo yokuskena yemodi yokugxila yangaphambilini iyindawo ene-hemispherical, njengoba kuboniswe esithombeni esingakwesokunxele. Indlela ye-post-focus scanning iboniswa esithombeni kwesokudla. Ilensi yenhloso iyilensi ye-F-plan. Isibuko se-F- plan sinomklamo okhethekile wokubona. Ngokwethula ukulungiswa kwe-optical, indawo egxilile ye-hemispherical ye-laser beam ingalungiswa ibe isicaba. I-post-focus scanning ifaneleka kakhulu izinhlelo zokusebenza ezidinga ukunemba okuphezulu kokucubungula kanye nebanga elincane lokucubungula, elifana nokumaka nge-laser, i-laser microstructure welding, njll.
2.Ilensi yokuskena egxile ngemuva
Njengoba indawo yokuskena ikhula, ukuvuleka kwelensi ye-f-theta nakho kuyanda. Ngenxa yemikhawulo yobuchwepheshe nempahla, amalensi e-f-theta anembobo enkulu abiza kakhulu futhi lesi sixazululo asamukelwa. Inhloso ye-lens front galvanometer scanning system ehlanganiswe nerobhothi ene-eksisi eyisithupha iyisixazululo esingenzeka, esinganciphisa ukuncika emishinini ye-galvanometer, inezinga elikhulu lokunemba kwesistimu, futhi inokuhambisana okuhle. Lesi sixazululo samukelwe iningi labadidiyeli. I-Adopt, ngokuvamile ebizwa ngokuthi i-flight welding. Ukushiselwa kwe-module busbar, okuhlanganisa ukuhlanzwa kwezigxobo, kunezinhlelo zokusebenza zendiza, ezingakhuphula ububanzi bokucubungula ngokuguquguqukayo nangempumelelo.
I-galvanometer ye-3.3D:
Kungakhathaliseki ukuthi ukuskena okugxile phambili noma ukuskena okugxile ngemuva, ukugxila kwe-laser beam akukwazi ukulawulwa ngokugxila okuguquguqukayo. Ngemodi yokuskena okugxilwe kuyo ngaphambili, lapho ucezu lokusebenza oluzocutshungulwa luncane, ilensi yokugxilisa ingqondo inobubanzi obuthile bokujula obugxilile, ngakho ingakwazi ukwenza ukuskena okugxilile ngefomethi encane. Kodwa-ke, uma indiza ezoskeniwa inkulu, amaphuzu aseduze nendawo azobe engagxilile kuyo futhi awakwazi ukugxila endaweni yokusebenza ezocutshungulwa ngenxa yokuthi idlula ububanzi bokujula be-laser focus. Ngakho-ke, lapho i-laser beam idingeka ukuthi igxile kahle kunoma isiphi isimo endizeni yokuskena futhi indawo yokubuka inkulu, ukusetshenziswa kwelensi yobude obugxilile obugxilile akukwazi ukuhlangabezana nezimfuneko zokuskena. Isistimu yokugxila eguquguqukayo iyisethi yamasistimu okubona ubude bayo bokugxila bungashintsha njengoba kudingeka. Ngakho-ke, abacwaningi bahlongoza ukusebenzisa ilensi yokugxila eguquguqukayo ukuze kunxeshezelwe umehluko wendlela yokubona, futhi basebenzise ilensi econcave (i-expander ye-beam) ukuze ihambe ngokulandelana eduze kwe-eksisi yokubona ukuze ulawule indawo yokugxila futhi uzuze Indawo okumele icutshungulwe ngokushintshashintshayo inxephezela i-optical. umehluko wendlela ezikhundleni ezahlukene. Uma kuqhathaniswa ne-galvanometer ye-2D, ukwakheka kwe-galvanometer ye-3D ngokuyinhloko yengeza "isistimu ye-Z-axis optical", ukuze i-galvanometer ye-3D ingakwazi ukushintsha ngokukhululekile indawo yokugxila ngesikhathi senqubo yokushisela futhi yenze indawo yokushisela egobile, ngaphandle kwesidingo sokushintsha. inkampani yenethiwekhi njengethuluzi lomshini, njll. njenge-galvanometer ye-2D. Ukuphakama kwerobhothi kusetshenziselwa ukulungisa indawo yokugxila yokushisela.
