Ikhanda eligxilile elihlanganisayo lisebenzisa umshini njengeplatifomu esekelayo, futhi liya emuva naphambili ngomshini womshini ukuze kuzuzwe ukushiselwa kwama-welds ngama-trajectories ahlukene. 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 ukuphambukisa ilensi. I-motor ishayelwa i-current ethile futhi inezinzuzo zokunemba okuphezulu, inertia encane, nokuphendula okusheshayo. Lapho i-beam yokukhanya ikhanyiswa kulensi ye-galvanometer, ukuchezuka kwe-galvanometer kushintsha i-engeli yokubonakala kwe-laser beam. Ngakho-ke, i-laser beam ingaskena noma iyiphi i-trajectory emkhakheni wokuskena wokubuka ngohlelo lwe-galvanometer. Ikhanda eliqondile elisetshenziswe ohlelweni lwe-robotic welding uhlelo lokusebenza olusekelwe kulesi simiso.
Izingxenye eziyinhloko ze-uhlelo lokuskena lwe-galvanometerkukhona i-collimator yokwandisa ugongolo, ilensi egxilile, i-galvanometer yokuskena ye-XY yama-axis amabili, ibhodi lokulawula kanye nesistimu yesoftware yekhompyutha. 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 yokuskena ye-XY dual-axis ukuze iphambukise ku-X-eksisi kanye ne-Y-eksisi ngokulandelana ngokuthumela amasiginali womyalo kumamotho we-servo e-X kanye ne-Y. Ngale ndlela, ngokunyakaza okuhlangene kwe-XY-axis mirror lens, uhlelo lokulawula lungaguqula isignali ngebhodi le-galvanometer ngokwethempulethi yehluzo ezisethiwe zesofthiwe yekhompiyutha ephethe kanye nemodi yomzila omisiwe, futhi ngokushesha ukuhambisa. endizeni yesiqeshana sokusebenzela ukwenza umzila wokuskena.

Ngokobudlelwano bendawo phakathi kwelensi egxilile ne-laser galvanometer, imodi yokuskena ye-galvanometer ingahlukaniswa ibe ukuskena okugxilwe ngaphambili (isithombe kwesokunxele) kanye nokuskena okugxile emuva (isithombe kwesokudla). Ngenxa yokuba khona komehluko wendlela yokubona lapho i-laser beam ichezukela ezindaweni ezihlukene (ibanga lokudluliswa kwe-beam lihlukile), indiza egxilile ye-laser enqubweni yokuskena yokugxila yangaphambilini iyindawo egobile ene-hemispherical, njengoba kuboniswe esithombeni esingakwesokunxele. Indlela yokuskena egxile emuva iboniswa emfanekisweni olungile, lapho ilensi yenhloso iyilensi yenkundla eyisicaba. Ilensi yenkundla eyisicaba inomklamo okhethekile wokukhanya.
Ngokwethula ukulungiswa kwe-optical, indiza ye-hemispherical focal ye-laser beam ingalungiswa ibe indiza. Ukuskena kokugxila emuva kulungele ikakhulukazi izinhlelo zokusebenza ezinezidingo eziphezulu zokunemba kokucubungula kanye nobubanzi obuncane bokucubungula, njengokumaka i-laser, i-laser microstructure welding, njll. Njengoba indawo yokuskena ikhula, ukuvuleka kwelensi nakho kuyanda. Ngenxa yokulinganiselwa kwezobuchwepheshe kanye nezinto ezibonakalayo, intengo ye-flenses enkulu-aperture ibiza kakhulu, futhi lesi sixazululo asamukelwa. Inhlanganisela yesistimu yokuskena ye-galvanometer phambi kwelensi yenhloso kanye nerobhothi ene-axis eyisithupha kuyisixazululo esingase sinciphise ukuncika emishinini ye-galvanometer, futhi ingaba nezinga elikhulu lokunemba kwesistimu nokuhambisana okuhle. Lesi sixazululo samukelwe ngabadidiyeli abaningi, okuvame ukubizwa ngokuthi i-flying welding. I-welding ye-module busbar, kuhlanganise nokuhlanzwa kwesigxobo, inezinhlelo zokusebenza ezindizayo, ezingase zikhulise ngokuguquguqukayo nangempumelelo ifomethi yokucubungula.
Noma ngabe ukuskena okugxilwe ngaphambili noma ukuskena okugxile ngemuva, ukugxila kwe-laser beam akukwazi ukulawulwa ngokugxila okuguquguqukayo. Kumodi yokuskena okugxilwe ngaphambili, lapho ucezu lokusebenza oluzocutshungulwa luncane, ilensi yokugxilisa ingqondo inobubanzi obujulile bokugxila, ngakho ingakwazi ukwenza ukuskena okugxilile ngefomethi encane. Kodwa-ke, lapho indiza ezoskeniwa inkulu, amaphuzu aseduze nendawo yomngcele ngeke agxilwe futhi awakwazi ukugxila endaweni yokusebenza ezocutshungulwa ngenxa yokuthi yeqa imikhawulo engaphezulu nephansi yokujula kwe-laser focal. 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 iyisistimu yokubona ubude bayo bokugxila bungashintshwa njengoba kudingeka. Ngakho-ke, ngokusebenzisa i-lens yokugxila eguquguqukayo ukuze kunxeshezelwe umehluko wendlela yokubona, ilensi ye-concave (i-expander ye-beam) ihamba ngomugqa eduze kwe-eksisi yokubona ukuze ilawule indawo yokugxila, ngaleyo ndlela izuze isinxephezelo esiguqukayo somehluko wendlela yokubona yendawo ezocutshungulwa. ezikhundleni ezahlukene. Uma kuqhathaniswa ne-galvanometer ye-2D, ukwakheka kwe-galvanometer ye-3D yengeza ikakhulukazi "isistimu ye-Z-axis optical", evumela i-galvanometer ye-3D ukuthi iguqule ngokukhululekile indawo yokugxila phakathi nenqubo yokushisela futhi yenze indawo yokushisela egobile, ngaphandle kwesidingo sokulungisa ukushisela. indawo yokugxila ngokushintsha ubude benkampani yenethiwekhi njengethuluzi lomshini noma irobhothi njenge-galvanometer engu-2D.
Isistimu yokugxila eguquguqukayo ingashintsha inani le-defocus, iguqule usayizi wendawo, ibone ukulungiswa kokugxila kwe-Z-axis, kanye nokucubungula kwezinhlangothi ezintathu.
Ibanga lokusebenza lichazwa njengebanga ukusuka kunqenqema olungaphambili kakhulu lwelensi ukuya endizeni egxilile noma endizeni yokuskena yomgomo. Qaphela ukuthi ungaphambanisi lokhu ngobude obusebenzayo bokugxila (EFL) benhloso. Lokhu kukalwa kusukela endizeni eyinhloko, indiza ecatshangelwayo lapho lonke uhlelo lwamalensi kucatshangwa ukuthi luyahlehla, kuya endizeni egxilile yesistimu yokubona.
