Laser scanner, inonziwo laser galvanometer, ine XY optical scanning musoro, electronic drive amplifier uye optical reflection lens. Chiratidzo chinopihwa nemutongi wekombuta chinotyaira musoro wekutarisa kuburikidza nekutyaira amplifier wedunhu, nekudaro ichidzora kutsauka kwelaser beam muXY ndege. Kungotaura zviri nyore, iyo galvanometer is scanning galvanometer inoshandiswa muindasitiri yelaser. Izwi rayo reunyanzvi rinonzi high-speed scanning galvanometer Galvo scanning system. Iyo inonzi galvanometer inogonawo kunzi ammeter. Yayo dhizaini zano rinotevera zvizere nzira yekugadzira yeammeter. Iyo lens inotsiva tsono, uye chiratidzo cheprobe chinotsiviwa nekombuta-inodzorwa -5V-5V kana -10V-+10V DC chiratidzo. , kupedzisa chiito chakafanorongwa. Kufanana negirazi rinotenderera rekuongorora system, iyi yakajairwa yekudzora sisitimu inoshandisa maviri ekudzoreredza magirazi. Musiyano ndewekuti iyo stepper mota inotyaira iyi seti yemalenzi inotsiviwa ne servo mota. Mune ino control system, sensor yenzvimbo inoshandiswa Iyo dhizaini yedhizaini uye yakashata mhinduro loop inowedzera kuve nechokwadi cheiyo sisitimu, uye kumhanya kwekutarisa uye kudzokororwa kwekumira kweiyo system yese kusvika padanho idzva. Iyo galvanometer scanning yekumaka musoro inonyanya kuumbwa neXY scanning mirror, field lens, galvanometer uye komputa-inodzorwa yekumaka software. Sarudza inoenderana optical zvikamu zvinoenderana akasiyana laser wavelengths. Sarudzo dzinoenderana dzinosanganisirawo laser beam expanders, lasers, etc. Mulaser demonstration system, waveform ye optical scanning ndeye vector scan, uye kumhanyisa kumhanyisa kwesystem kunotarisa kugadzikana kweiyo laser pateni. Mumakore achangopfuura, ma scanner akakwira-kumhanya akagadzirwa, nekumhanyisa kumhanya kunosvika 45,000 mapoinzi/sekondi, zvichiita kuti zvikwanise kuratidza yakaoma laser animations.
5.1 Laser galvanometer welding joint
5.1.1 Tsanangudzo uye kuumbwa kwegalvanometer welding joint:
Iyo collimation inotarisa musoro inoshandisa mechanical mudziyo sechikuva chinotsigira. Iyo mechanical mudziyo inofamba ichidzokera kumashure kuti iwane welding yeakasiyana trajectory welds. Kurongeka kwewelding kunoenderana nekurongeka kweiyo actuator, saka kune matambudziko akadai sekuderera kwechokwadi, kunonoka kupindura nekukurumidza, uye inertia hombe. Iyo galvanometer scanning system inoshandisa mota kutakura lenzi yekutsauka. Iyo mota inotyairwa neimwe yazvino uye ine mabhenefiti eiyo chaiyo chaiyo, diki inertia, uye nekukurumidza kupindura. Kana danda rikavhenekerwa pane galvanometer lens, kutsauka kwe galvanometer kunoshandura laser danda. Naizvozvo, iyo laser beam inogona kuongorora chero trajectory mumunda wekutarisa wekutarisa kuburikidza negalvanometer system.
Izvo zvakakosha zveiyo galvanometer scanning system ndeye danda rekuwedzera collimator, inotarisisa lens, XY maviri-axis scanning galvanometer, control board uye host komputa software system. Iyo scanning galvanometer inonyanya kureva misoro miviri yeXY galvanometer yekuongorora, iyo inofambiswa nepamusoro-kumhanya kudzoreredza servo motors. Iyo mbiri-axis servo system inotyaira iyo XY mbiri-axis scanning galvanometer kutsauka ichitevedza X-axis uye Y-axis zvakateerana nekutumira masaini ekuraira kuX uye Y-axis servo motors. Nenzira iyi, kuburikidza nekufamba kwakabatanidzwa kweXY maviri-axis mirror lens, iyo control system inogona kushandura chiratidzo kuburikidza negalvanometer board zvinoenderana neyakagadzikwa graphic template yeahost komputa software zvinoenderana nenzira yakatarwa, uye nekukurumidza kufamba pa workpiece ndege kuti iite scanning trajectory.
5.1.2 Kukamurwa kwegalvanometer welding joints:
1. Mberi yakanangana nekuvheneka lenzi
Zvinoenderana nehukama hwenzvimbo pakati peinotarisisa lenzi nelaser galvanometer, iyo yekuvheneka modhi yegalvanometer inogona kupatsanurwa kuita kumberi kutarisisa scanning (Mufananidzo 1 pazasi) uye kumashure kutarisisa kutarisa (Mufananidzo 2 pazasi). Nekuda kwekuvapo kweiyo optical nzira musiyano kana laser beam yakatsauswa kune akasiyana zvinzvimbo (iyo danda rekufambisa kureba rakasiyana), iyo laser focal surface panguva yepamberi yekutarisisa modhi yekuongorora maitiro inzvimbo yehemispherical, sezvakaratidzwa mumufananidzo wekuruboshwe. Iyo post-focus scanning nzira inoratidzwa mumufananidzo uri kurudyi. Iyo lenzi yechinangwa ndeye F-chirongwa lens. Chionioni cheF-chirongwa chine dhizaini yakakosha. Nekuunza kururamisa kwemaziso, iyo hemispherical focal pamusoro peiyo laser beam inogona kugadziridzwa kuita flat. Post-focus scanning inonyanya kukodzera kune zvikumbiro zvinoda kurongeka kwepamusoro uye diki yekugadzirisa renji, senge laser yekumaka, laser microstructure welding, nezvimwe.
2.Rear inotarisa kutarisisa lens
Sezvo nzvimbo yekuongorora ichiwedzera, iyo aperture yef-theta lens inowedzerawo. Nekuda kwekugumira kwehunyanzvi uye kwezvinhu, hombe-aperture f-theta lenzi inodhura zvakanyanya uye mhinduro iyi haigamuchirwe. Chinangwa chelenzi kumberi galvanometer scanning system yakasanganiswa neye matanhatu-axis robhoti imhinduro inogoneka, inogona kuderedza kutsamira pamidziyo yegalvanometer, ine dhigirii yakakura yehurongwa hwechokwadi, uye inoenderana zvakanaka. Iyi mhinduro yakagamuchirwa nevazhinji vanobatanidza. Adopt, inowanzonzi ndege welding. Iyo welding yemodule busbar, kusanganisira kuchenesa danda, ine ndege yekushandisa, iyo inogona kuwedzera hupamhi hwekugadzirisa zviri nyore uye zvinobudirira.
3.3D galvanometer:
Kunyangwe iri kumberi-yakatarisana scanning kana kumashure-yakatarisana scanning, iyo yakatarisana neye laser beam haigone kudzorwa kuti itarise zvine simba. Kune iyo yekumberi yekutarisisa modhi, kana iyo workpiece ichagadziriswa idiki, iyo inotarisisa lenzi ine yakatarisana nehupamhi hwehupamhi, saka inogona kuita yakatariswa scanning ine diki fomati. Nekudaro, kana ndege ichaongororwa yakakura, mapoinzi ari padyo nepariphery anenge asisina kutariswa uye haagone kunangana pamusoro peiyo workpiece kuti igadziriswe nekuti inodarika kudzika kweiyo laser focus. Naizvozvo, kana danda relaser richidikanwa kuti rinyatso kutariswa pane chero chinzvimbo pandege yekuongorora uye munda wekuona wakakura, kushandiswa kweiyo yakagadziriswa yakatarisa kureba lens haigone kusangana nezvinodiwa zvekuongorora. Iyo dynamic focusing system ndeye seti ye optical masisitimu ayo akatarisana nehurefu hunogona kuchinja sezvinodiwa. Naizvozvo, vatsvakurudzi vanokurudzira kushandisa dynamic focusing lens kubhadharira iyo optical nzira musiyano, uye shandisa concave lens (beam expander) kufamba nemutsara pamwe neaxis yemaziso kudzora nzvimbo yekutarisa uye kuwana Iyo yepamusoro inogadziriswa zvine simba inotsiva iyo yekuona. musiyano wenzira panzvimbo dzakasiyana. Kuenzaniswa ne2D galvanometer, kuumbwa kwe3D galvanometer kunonyanya kuwedzera "Z-axis optical system", kuitira kuti 3D galvanometer inogona kusununguka kushandura nzvimbo yekutarisa panguva yewelding process uye kuita spatial curved surface welding, pasina chikonzero chekuchinja. mutakuri akadai semuchina chishandiso, nezvimwewo se2D galvanometer. Kureba kwerobhoti kunoshandiswa kugadzirisa iyo welding yekutarisa chinzvimbo.
