Intloko egxininisekileyo ye-collimating isebenzisa isixhobo somatshini njengeqonga elixhasayo, kwaye lihamba ngasemva naphambili ngesixhobo somatshini ukufezekisa i-welding ye-welds eneendlela 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 ukuphambuka kwi-lens. I-motor iqhutywa ngumsinga othile kwaye ineenzuzo zokuchaneka okuphezulu, inertia encinci, kunye nokuphendula ngokukhawuleza. Xa umqadi wokukhanya ukhanyisa kwi-galvanometer lens, ukuphambuka kwe-galvanometer kutshintsha i-angle yokubonakalisa i-laser beam. Ngoko ke, i-laser beam inokuskena nayiphi na i-trajectory kwintsimi yokujonga nge-galvanometer system. Intloko ethe nkqo esetyenziswe kwi-robotic welding system sisicelo esisekelwe kulo mgaqo.
Amacandelo aphambili einkqubo yokuskena i-galvanometerI-collimator yokwandisa i-beam, 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 ye-servo motors. Ngale ndlela, ngokusebenzisa intshukumo edityanisiweyo ye-XY-axis-mirror mirror lens, inkqubo yokulawula inokuguqula umqondiso ngebhodi ye-galvanometer ngokwethempleyithi yegraphics esetwe ngaphambili yesoftware yekhompyuter kunye nemowudi yomendo omiselweyo, kwaye ngokukhawuleza uhambe. kwinqwelomoya yomsebenzi ukwenza umkhondo wokuskena.

Ngokobudlelwane bendawo phakathi kwe-lens egxininisekileyo kunye ne-laser galvanometer, imowudi yokuskena ye-galvanometer inokwahlulwa ibe yi-scanning yangaphambili (umfanekiso osekhohlo) kunye nokujolisa ngasemva ukuskena (umfanekiso wasekunene). Ngenxa yobukho bomehluko wendlela ye-optical xa umqadi welaser ujikela kwizikhundla ezahlukeneyo (umgama wokuhambisa umqadi wahlukile), inqwelomoya yogxininiso yelaser kwinkqubo yokujolisa edlulileyo yokuskena ngumphezulu ogobileyo we-hemispherical, njengoko kubonisiwe kumfanekiso osekhohlo. Indlela yokujolisa ngasemva iboniswe kumzobo ochanekileyo, apho i-lens yenjongo yi-lens yebala elicaba. I-lens ye-flat field inoyilo olukhethekileyo lwe-optical.
Inkqubo yeRobhothi yokuWelding
Ngokuzisa ukulungiswa kwe-optical, i-hemispherical focal plane ye-laser beam inokulungiswa kwinqwelomoya. Ukujongwa kokujolisa umva ngokuyintloko kufanelekile kwizicelo ezineemfuno zokuchaneka okuphezulu kunye noluhlu oluncinci lokucubungula, njengokumakisha kwe-laser, i-laser microstructure welding, njl. Njengoko indawo yokuskena isanda, ukuvuleka kwe-lens kuyanda. Ngenxa yokulinganiselwa kwezobugcisa kunye nezinto eziphathekayo, ixabiso leeflense ezinkulu ze-aperture libiza kakhulu, kwaye esi sisombululo asimkelwa. Ukudityaniswa kwenkqubo yokuskena ye-galvanometer phambi kwelensi yenjongo kunye nerobhothi ene-axis ezintandathu sisisombululo esinokwenzeka esinokunciphisa ukuxhomekeka kwisixhobo se-galvanometer, kwaye sinokuba nenqanaba elibonakalayo lokuchaneka kwenkqubo kunye nokuhambelana okuhle. Esi sisombululo samkelwe ngabadibanisi abaninzi, okuhlala kubizwa ngokuba yi-flying welding. I-welding ye-module busbar, kubandakanywa nokucocwa kwepali, inezicelo ezibhabhayo, ezinokuthi ziguquguquke kwaye zikhulise ngokufanelekileyo ifomathi yokucubungula.
Nokuba kukukhangela okuphambili okanye kujoliso lwangasemva, ugxininiso lwesibane selaser alukwazi ukulawulwa ukugxila okuguquguqukayo. Kwimowudi yokujolisa ngaphambili, xa i-workpiece izakucutshungulwa incinci, i-lens egxininisiweyo inoluhlu oluthile lobunzulu obugxininisekileyo, ngoko ke inokwenza ukujolisa ukuskena ngefomathi encinci. Nangona kunjalo, xa inqwelomoya eza kuskeniwa inkulu, iindawo ezikufutshane nomda womjikelezo aziyi kugxininiswa kwaye azinakujoliswa kumphezulu wesixhobo sokusetyenzwa ukuze sisetyenzwe ngenxa yokuba yodlula imida ephezulu nasezantsi yobunzulu belaser. 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 yokugxila eguquguqukayo yinkqubo ye-optical ubude bayo obugxininise bunokutshintshwa njengoko kufuneka. Ngoko ke, ngokusebenzisa i-lens eguquguqukayo egxininisekile ukuhlawulela umahluko wendlela yokubona, i-lens yeconcave (i-expander ye-beam) ihamba ngomgca ecaleni kwe-axis ye-optical ukulawula indawo ekugxilwe kuyo, ngaloo ndlela ifezekisa imbuyekezo eguquguqukayo yomahluko wendlela yokukhanya yomphezulu ekufuneka iqwalaselwe. kwizikhundla ezahlukeneyo. Xa kuthelekiswa ne-galvanometer ye-2D, ukwakheka kwe-galvanometer ye-3D yongeza ikakhulu "inkqubo ye-Z-axis optical", evumela i-galvanometer ye-3D ukuba itshintshe ngokukhululekileyo indawo ekugxilwe kuyo ngexesha lenkqubo ye-welding kwaye yenze i-spatial curved surface welding, ngaphandle kwesidingo sokulungelelanisa ukuwelda. indawo yokugxila ngokutshintsha ubude bomthwali njengesixhobo somatshini okanye irobhothi njenge2D galvanometer.
Inkqubo yogxininiso eguquguqukayo inokutshintsha inani le-defocus, itshintshe ubungakanani bendawo, iqonde uhlengahlengiso lwe-Z-axis, kunye nokusetyenzwa kwe-dimensional ezintathu.
Umgama wokusebenza uchazwa njengomgama ukusuka kumda ongaphambili-owona matshini we-lens ukuya kwinqwelomoya okanye kwinqwelomoya yokuskena injongo. Qaphela ukuba ungabhidanisi oku kunye nobude bojoliso obusebenzayo (EFL) benjongo. Oku kulinganiswa ukusuka kwinqwelo-moya eyintloko, inqwelo-moya eqikelelwayo apho yonke inkqubo ye-lens ithathwa njenge-refract, kwi-focal plane ye-optical system.
