I-Laser scanner, ekwabizwa ngokuba yi-laser galvanometer, inentloko ye-XY yokuskena, iamplifier ye-electronic drive kunye ne-optical reflection lens. Umqondiso onikezelwe ngumlawuli wekhompyutheni uqhuba intloko ye-optical scanning ngokusebenzisa isiphaluka se-amplifier yokuqhuba, ngaloo ndlela ilawula ukuphambuka kwe-laser beam kwindiza ye-XY. Ukuthetha nje, igalvanometer yi-galvanometer yokuskena esetyenziswa kushishino lwelaser. Igama layo lobuchwephesha libizwa ngokuba yinkqubo yokuskena ekhawulezayo ye-galvanometer ye-Galvo. Into ebizwa ngokuba yi-galvanometer inokubizwa ngokuba yi-ammeter. Ingcamango yoyilo lwayo ilandela ngokupheleleyo indlela yoyilo yeammeter. I-lens ithatha indawo yenaliti, kwaye umqondiso weprobe utshintshwa yi-computer-controlled -5V-5V okanye -10V-+10V DC. , ukugqiba isenzo esimiswe kwangaphambili. Njengenkqubo yokuskena yesipili esijikelezayo, le nkqubo yolawulo eqhelekileyo isebenzisa iperi yezibuko ezibuyisela umva. Umahluko kukuba i-motor stepper eqhuba le seti yeelensi ithathelwa indawo yi-servo motor. Kule nkqubo yokulawula, i-sensor yesikhundla isetyenzisiweyo Ingcamango yoyilo kunye ne-negative feedback loop iqinisekisa ngakumbi ukuchaneka kwenkqubo, kunye nesantya sokuskena kunye nokuphindaphinda ukuchaneka kokumiswa kwenkqubo yonke ukufikelela kwinqanaba elitsha. Intloko yokumakisha i-galvanometer iquka isibuko sokuskena se-XY, i-lens yasendle, i-galvanometer kunye nesofthiwe yokumakisha elawulwa yikhompyutha. Khetha amacandelo optical ahambelanayo ngokwee-laser wavelengths ezahlukeneyo. Iinketho ezinxulumene nazo zibandakanya izandisi ze-laser beam, i-laser, njl. Kwinkqubo yokubonisa i-laser, i-waveform ye-optical scanning yi-scan ye-vector, kwaye isantya sokuskena senkqubo simisela ukuzinza kwepateni ye-laser. Kwiminyaka yakutshanje, iiskena ezinesantya esiphezulu ziphuhlisiwe, kunye nezantya zokuskena ezifikelela kumanqaku angama-45,000 / ngomzuzwana, okwenza kube lula ukubonisa oopopayi belaser.
5.1 Laser galvanometer welding joint
5.1.1 Inkcazo kunye nokwakhiwa kwe-galvanometer ye-welding joint:
Intloko yokugxila kwi-collimation isebenzisa isixhobo somatshini njengeqonga elixhasayo. Isixhobo somatshini sihamba ngasemva naphambili ukuze sifezekise i-welding ye-welds yeendlela ezahlukeneyo. Ukuchaneka kwe-welding kuxhomekeke ekuchanekeni kwe-actuator, ngoko kukho iingxaki ezifana nokuchaneka okuphantsi, isantya sokuphendula esicothayo, kunye ne-inertia enkulu. Inkqubo yokuskena i-galvanometer isebenzisa i-motor ukuthwala i-lens ukuphambuka. I-motor iqhutywa ngumsinga othile kwaye ineenzuzo zokuchaneka okuphezulu, inertia encinci, kunye nokuphendula ngokukhawuleza. Xa umqadi ukhanyiswa kwi-galvanometer lens, ukuphambuka kwe-galvanometer kutshintsha i-laser beam. Ngoko ke, i-laser beam inokuskena nayiphi na i-trajectory kwintsimi yokujonga nge-galvanometer system.
Amacandelo aphambili enkqubo yokuskena i-galvanometer yi-collimator yokwandisa i-boam, i-lens egxininisekileyo, i-XY ye-axis yokuskena i-galvanometer, ibhodi yokulawula kunye nenkqubo yesoftware yekhompyutha. I-galvanometer yokuskena ibhekisa ikakhulu kwiintloko ezimbini ze-XY galvanometer zokuskena, eziqhutywa ziimotor ze-servo ezibuyisela ngesantya esiphezulu. Inkqubo ye-servo ye-double-axis iqhuba i-galvanometer ye-XY ye-double-axis scanning ukuze ijike ecaleni kwe-X-axis kunye ne-Y-axis ngokulandelelana ngokuthumela imiqondiso yomyalelo kwi-X kunye ne-Y-axis servo motors. Ngale ndlela, ngentshukumo edityanisiweyo ye-lens yesipili ye-XY, inkqubo yokulawula inokuguqula umqondiso ngebhodi ye-galvanometer ngokwe-template esetyenzisiweyo yegraphic ye-software yekhompyutha yomkhosi ngokwendlela emiselweyo, kwaye ngokukhawuleza uhambe indiza yokusebenza ukwenza umkhondo wokuskena.
5.1.2 Ukuhlelwa kwee-galvanometer ze-welding joints:
1. Ilensi yokujonga ngaphambili ejongiswe ngaphambili
Ngokobudlelwane bendawo phakathi kwe-lens yokugxila kunye ne-laser galvanometer, imowudi yokuskena ye-galvanometer inokwahlulwa ibe yi-scanning yangaphambili egxininisekileyo (Umfanekiso 1 ngezantsi) kwaye ngasemva ugxininise ukuskena (Umfanekiso 2 ngezantsi). Ngenxa yobukho bomehluko wendlela ye-optical xa i-laser beam ijikisiwe kwizikhundla ezahlukeneyo (umgama wokuhambisa umqadi uhlukile), i-laser focal surface ngexesha lenkqubo yokujonga imowudi yangaphambili ingumphezulu we-hemispherical, njengoko kubonisiwe kumfanekiso osekhohlo. Indlela yokukhangela emva kokugxila iboniswe kumfanekiso osekunene. Ilensi yenjongo yiF-plan lens. Isibuko se-F- plan sinoyilo olukhethekileyo lwamehlo. Ngokuzisa ukulungiswa kwe-optical, i-hemispherical focal surface ye-laser beam inokulungelelaniswa kwi-flat. I-Post-focus scanning ifaneleka kakhulu kwizicelo ezifuna ukuchaneka okuphezulu kokucubungula kunye noluhlu oluncinci lokucubungula, njengokumakisha kwe-laser, i-laser microstructure welding, njl.
2.Ilensi yokujonga ngasemva
Njengoko indawo yokuskena isanda, i-aperture ye-f-theta lens nayo iyanda. Ngenxa yokulinganiselwa kobugcisa kunye nezinto eziphathekayo, iilensi ezinkulu ze-f-theta zibiza kakhulu kwaye esi sisombululo asamkelwa. Inkqubo yokuskena ye-lens yangaphambili ye-galvanometer idityaniswe ne-robot ye-axis emithandathu sisisombululo esinokwenzeka, esinokunciphisa ukuxhomekeka kwisixhobo se-galvanometer, inomlinganiselo omkhulu wokuchaneka kwenkqubo, kwaye ihambelana kakuhle. Esi sisombululo samkelwe luninzi lwabahlanganisi. I-Adopt, edla ngokubizwa ngokuba yi-flight welding. I-welding ye-module busbar, kubandakanywa nokucoca i-pole, inezicelo zendiza, ezinokunyusa ububanzi bokucubungula ngokuguquguqukayo nangokufanelekileyo.
3.3D igalvanometer:
Nokuba kujongwe ngaphambili ukuskena okanye kugxilwe ngasemva, ugxininiso lomqadi we-laser alukwazi ukulawulwa ukugxila okuguquguqukayo. Kwimowudi yojoliso lwangaphambili, xa umsebenzi oza kucutshungulwa umncinci, ilensi yokugxila inoluhlu oluthile lobunzulu, ngoko ke inokwenza ukuskena okugxilileyo ngefomathi encinci. Nangona kunjalo, xa inqwelomoya eza kuskeniwa inkulu, iindawo ezikufutshane nomda womjikelezo ziya kuba zingagxininiswa kwaye azinakujoliswa kumphezulu wesixhobo sokusetyenzwa ukuze sisetyenzwe ngenxa yokuba idlula ubunzulu bojoliso lwelaser. Ngoko ke, xa i-laser beam ifunwa ukuba igxininise kakuhle nakweyiphi na indawo kwinqwelo-moya yokuskena kwaye intsimi yokujonga inkulu, ukusetyenziswa kwe-lens egxininisiweyo yobude obugxininisiweyo ayikwazi ukuhlangabezana neemfuno zokuskena. Inkqubo yogxininiso eguquguqukayo yiseti yeenkqubo ze-optical ubude bayo obugxininise bunokutshintsha njengoko kufuneka. Ngoko ke, abaphandi bacebisa ukusebenzisa i-lens egxininisekile eguquguqukayo ukuhlawulela umahluko wendlela ye-optical, kwaye basebenzise i-lens ye-concave (i-expander ye-beam) ukuhamba ngomgca kunye ne-optical axis ukulawula indawo ekugxilwe kuyo kunye nokufezekisa Umphezulu oza kucutshungulwa ngokuguquguqukayo uhlawulela i-optical. Umahluko wendlela kwiindawo ezahlukeneyo. Xa kuthelekiswa ne-galvanometer ye-2D, ukubunjwa kwe-galvanometer ye-3D yongeza ngokukodwa "inkqubo ye-Z-axis optical", ukuze i-galvanometer ye-3D itshintshe ngokukhululekileyo indawo ekugxilwe kuyo ngexesha lenkqubo ye-welding kwaye yenze i-spatial curved surface welding, ngaphandle kwesidingo sokutshintsha. umthwali onjengesixhobo somatshini, njl njl njenge-galvanometer ye-2D. Ukuphakama kwerobhothi kusetyenziselwa ukulungisa indawo yokugxila kwi-welding.
