Laser scanner, inonziwo laser galvanometer, ine XY optical scanning head, electronic drive amplifier uye optical reflection lens. Chiratidzo chinopihwa necomputer controller chinofambisa optical scanning head kuburikidza nedriveing amplifier circuit, nokudaro chichidzora kutsauka kwelaser beam muXY plane. Kutaura zviri nyore, galvanometer iscanning galvanometer inoshandiswa muindasitiri yelaser. Izwi rayo rehunyanzvi rinonzi high-speed scanning galvanometer Galvo scanning system. Iyo inonzi galvanometer inogonawo kunzi ammeter. Pfungwa yayo yekugadzira inonyatsotevedzera nzira yekugadzira yeammeter. Lens inotsiva tsono, uye chiratidzo cheprobe chinotsiviwa necomputer-controlled -5V-5V kana -10V-+10V DC signal. , kuti ipedzise chiito chakatarwa. Kufanana nerotation mirror scanning system inotenderera, iyi system yekudzora yakajairika inoshandisa magirazi maviri anodzosera kumashure. Musiyano ndewekuti stepper motor inotyaira seti iyi yelenses inotsiviwa neservo motor. Muhurongwa uhwu hwekudzora, sensor yenzvimbo inoshandiswa. Pfungwa yekugadzira uye negative feedback loop inowedzera kuvimbisa kururama kwehurongwa, uye kumhanya kwekuskena uye kurongeka kwekudzokororwa kwehurongwa hwese zvinosvika padanho idzva. Musoro wekuskena wegalvanometer unonyanya kuumbwa neXY scanning mirror, field lens, galvanometer uye computer-controlled marking software. Sarudza zvikamu zvinoenderana ne laser wavelengths dzakasiyana. Sarudzo dzakabatana dzinosanganisirawo laser beam expanders, lasers, nezvimwewo. Muhurongwa hwe laser demonstration, waveform ye optical scanning i vector scan, uye kumhanya kwekuskena kwehurongwa kunosarudza kugadzikana kwe laser pattern. Mumakore achangopfuura, ma scanners ekumhanya kwepamusoro akagadzirwa, nekumhanya kwekuskena kuchisvika 45,000 points/sekondi, zvichiita kuti zvikwanisike kuratidza ma animations akaomarara e laser.
5.1 Joint yeLaser galvanometer yekuwedera
5.1.1 Tsanangudzo uye kuumbwa kwejoini yekuwelding yegalvanometer:
Musoro unotarisa collimation unoshandisa mudziyo wemakanika sepuratifomu inotsigira. Mudziyo wemakanika unofamba uchidzokera shure nekudzoka kuti uwane welding ye trajectory welds dzakasiyana. Kururama kwewelding kunoenderana nekururama kwe actuator, saka pane matambudziko akadai sekururama kushoma, kumhanya kunonoka kwemhinduro, uye inertia huru. Sisitimu yekuskena yegalvanometer inoshandisa mota kutakura lenzi kuti ienderere mberi. Mota inofambiswa nemagetsi akati wandei uye ine mabhenefiti ekururama kwakanyanya, inertia diki, uye mhinduro nekukurumidza. Kana danda ravhenekerwa pa galvanometer lens, kutsauka kwe galvanometer kunochinja danda re laser. Nokudaro, danda re laser rinogona kuskena chero nzira iri mu scanning field of view kuburikidza ne galvanometer system.
Zvikamu zvikuru zve galvanometer scanning system zvinosanganisira beam expansion collimator, focusing lens, XY two-axis scanning galvanometer, control board uye host computer software system. Scanning galvanometer inonyanya kureva maviri XY galvanometer scanning heads, ayo anofambiswa ne high-speed reciprocating servo motors. Dual-axis servo system inotyaira XY dual-axis scanning galvanometer kuti itsauke ichitevedza X-axis neY-axis zvichiteerana nekutumira masaini ekuraira kuX neY-axis servo motors. Nenzira iyi, kuburikidza nekufamba kwakabatana kweXY two-axis mirror lens, control system inogona kushandura chiratidzo kuburikidza negalvanometer board zvichienderana ne preset graphic template ye host computer software zvichienderana nenzira yakatarwa, uye nekukurumidza kufamba pa workpiece plane kuti igadzire scanning trajectory.
5.1.2 Kupatsanurwa kwemajoini ekusonerera egalvanometer:
1. Lenzi yekuskena inotarisa mberi
Zvichienderana nehukama huripo pakati pe lenzi yekutarisa ne laser galvanometer, nzira yekuongorora ye galvanometer inogona kukamurwa kuita front focusing scanning (Mufananidzo 1 pazasi) uye rear focusing focusing scanning (Mufananidzo 2 pazasi). Nekuda kwekuvapo kwemusiyano wenzira ye optical kana laser beam yakatsauswa kuenda kunzvimbo dzakasiyana (daro rekutumira beam rakasiyana), laser focal surface panguva yekuskena ye focus mode yapfuura i hemispherical surface, sezvakaratidzwa mumufananidzo wekuruboshwe. Nzira ye post-focus scanning inoratidzwa mumufananidzo uri kurudyi. Lenzi ye objective i F-plan lens. Girazi re F-plan rine dhizaini yakasarudzika ye optical. Nekuisa optical correction, hemispherical focal surface ye laser beam inogona kugadziriswa kuti ive flat. Post-focus scanning inonyanya kukodzera maapplication anoda high processing accuracy uye diki processing range, senge laser marking, laser microstructure welding, nezvimwewo.
2.Lenzi yekumashure inotarisa
Sezvo nzvimbo yekuskena ichiwedzera, mukana wekuvhura kwelenzi ye f-theta unowedzerawo. Nekuda kwezvipingamupinyi zvehunyanzvi uye zvezvinhu, lenzi dze f-theta dzine aperture hombe dzinodhura zvikuru uye mhinduro iyi haigamuchirwi. Sisitimu yekuskena ye lenzi yekumberi ye galvanometer pamwe chete ne robhoti ine axis nhanhatu mhinduro inogoneka, inogona kuderedza kuvimba nemidziyo ye galvanometer, ine mwero wakakura wekururama kwesystem, uye inoenderana zvakanaka. Mhinduro iyi yakagamuchirwa nevakawanda vanobatanidza. Adopt, inowanzonzi flight welding. Welding ye module busbar, kusanganisira kuchenesa pole, ine mashandisirwo ekubhururuka, ayo anogona kuwedzera upamhi hwekugadzirisa nenzira inochinjika uye inobudirira.
3.3D galvanometer:
Pasinei nekuti ingave scanning yakatarisana nemberi kana rear-focused scanning, focus yelaser beam haigone kudzorwa kuti ikwanise kutarisisa zvinhu zvine simba. Kune front focus scanning mode, kana workpiece inofanira kugadziriswa iri diki, focus lens ine focal depth range yakati, saka inogona kuita focused scanning ine format diki. Zvisinei, kana plane inofanira kutariswa yakakura, mapoinzi ari pedyo neperiphery haazoonekwi uye haagone kutariswa pamusoro peworkpiece inofanira kugadziriswa nekuti inodarika depth range ye laser focus. Naizvozvo, kana laser beam ichidikanwa kuti itarisiswe zvakanaka panzvimbo chero ipi zvayo pa scanning plane uye field of view yakakura, kushandiswa kwe fixed focal length lens hakugone kusangana nezvinodiwa zve scanning. Dynamic focus system i seti yema optical systems ane focal length inogona kuchinja sezvinodiwa. Nokudaro, vaongorori vanokurudzira kushandisa dynamic focus lens kuti vatsive musiyano we optical path, uye shandisa concave lens (beam expander) kuti ifambe yakatwasuka ichitevedza optical axis kuti idzore focus position uye iwane. Nzvimbo inofanira kugadziriswa inoripa musiyano we optical path panzvimbo dzakasiyana. Kana tichienzanisa ne 2D galvanometer, chimiro che 3D galvanometer chinonyanya kuwedzera "Z-axis optical system", kuitira kuti 3D galvanometer igone kuchinja nzvimbo yekutarisa panguva yekushongedza uye kuita spatial curved surface welding, pasina chikonzero chekuchinja carrier senge machine tool, nezvimwewo se 2D galvanometer. Kureba kwerobhoti kunoshandiswa kugadzirisa nzvimbo yekutarisa yekubatanidza.
