Inkqubo yokuWelda yeRobotic - Intloko yokuWelda yeGalvanometer

Intloko egxile kwi-collimating isebenzisa isixhobo soomatshini njengeqonga elixhasayo, kwaye ihambahamba isiya phambili nangasemva kwisixhobo soomatshini ukuze kufezekiswe ukuwelda kwee-welds ezineendlela ezahlukeneyo. Ukuchaneka kokuwelda kuxhomekeke ekuchanekeni kwe-actuator, ngoko ke kukho iingxaki ezifana nokuchaneka okuphantsi, isantya sokuphendula esicothayo, kunye ne-inertia enkulu. Inkqubo yokuskena ye-galvanometer isebenzisa i-motor ukujika ilensi. I-motor iqhutywa ngumbane othile kwaye ineenzuzo zokuchaneka okuphezulu, i-inertia encinci, kunye nempendulo ekhawulezayo. Xa umqadi wokukhanya ukhanyiswa kwilensi ye-galvanometer, ukujika kwe-galvanometer kutshintsha i-engile yokubonakalisa komqadi we-laser. Ke ngoko, umqadi we-laser unokuskena nayiphi na indlela kwindawo yokuskena yokujonga ngenkqubo ye-galvanometer. Intloko ethe nkqo esetyenziswa kwinkqubo yokuwelda ye-robotic sisicelo esisekelwe kulo mgaqo.

Izinto eziphambili zeinkqubo yokuskena i-galvanometeryi-beam expansion collimator, i-focusing lens, i-XY two-axis scanning galvanometer, ibhodi yokulawula kunye nenkqubo yesoftware yekhompyutha yomsingathi. I-scanning galvanometer ibhekisa ikakhulu kwiintloko ezimbini ze-XY galvanometer scanning, eziqhutywa zii-servo motors ezikhawulezayo. Inkqubo ye-servo ye-dual-axis iqhuba i-XY dual-axis scanning galvanometer ukuba iphambuke kwi-X-axis kunye ne-Y-axis ngokulandelanayo ngokuthumela imiqondiso yomyalelo kwii-X kunye ne-Y axis servo motors. Ngale ndlela, ngentshukumo edibeneyo yelensi yesibuko ye-XY two-axis, inkqubo yolawulo inokuguqula isignali ngebhodi ye-galvanometer ngokwetemplate yemizobo emiselweyo yesoftware yekhompyutha yomsingathi kunye nemo yendlela emiselweyo, kwaye ihambe ngokukhawuleza kwiplane yomsebenzi ukuze yenze i-scanning trajectory.

Ngokwendlela ekwakhiwe ngayo phakathi kwelensi yokugxila kunye ne-laser galvanometer, indlela yokuskena ye-galvanometer inokwahlulwahlulwa ibe yi-front focusing scanning (umfanekiso wasekhohlo) kunye ne-back focusing scanning (umfanekiso wasekunene). Ngenxa yokubakho komahluko wendlela ye-optical xa umqadi we-laser ujika uye kwiindawo ezahlukeneyo (umgama wokudluliselwa komqadi wahlukile), i-laser focal plane kwinkqubo yangaphambili yokuskena yokugxila ngumphezulu ogobileyo we-hemispherical, njengoko kubonisiwe kumfanekiso wasekhohlo. Indlela yokuskena yokugxila ngasemva iboniswe kumfanekiso wasekunene, apho ilensi ejolise kuyo yi-flat field lens. Ilensi ye-flat field inoyilo olukhethekileyo lwe-optical.

Inkqubo yokuWelda yeRobotic

Ngokwazisa ukulungiswa kwe-optical, i-hemispherical focal plane ye-laser beam inokulungiswa kwi-plane. Ukuskena okujolisa ngasemva kulungele kakhulu izicelo ezineemfuno eziphezulu zokuchaneka kokucubungula kunye noluhlu oluncinci lokucubungula, njengokumakishwa kwe-laser, ukuwelda kwe-laser microstructure, njl. Njengoko indawo yokuskena isanda, ukuvuleka kwelensi nako kuyakhula. Ngenxa yemida yobugcisa kunye nezinto ezibonakalayo, ixabiso le-large-aperture flenses libiza kakhulu, kwaye esi sisombululo asamkelwa. Ukudibanisa inkqubo yokuskena ye-galvanometer phambi kwelensi ejolise kuyo kunye nerobhothi ene-axis ezintandathu sisisombululo esinokwenzeka esinokunciphisa ukuxhomekeka kwizixhobo ze-galvanometer, kwaye sinokuba nomlinganiselo omkhulu wokuchaneka kwenkqubo kunye nokuhambelana okuhle. Esi sisombululo samkelwe ngabahlanganisi abaninzi, abadla ngokubizwa ngokuba yi-flying welding. Ukuwelda kwe-module busbar, kubandakanya nokucocwa kwepali, kunezicelo zokubhabha, ezinokunyusa ifomathi yokucubungula ngokuguquguqukayo nangokufanelekileyo.

Nokuba kukuskena okujolisa phambili okanye ukuskena okujolisa ngasemva, ugxininiso lomqadi welaser alunakulawulwa ukuze kugxilwe ngokuguquguqukayo. Kwimo yokuskena ejolisa phambili, xa umsebenzi oza kucutshungulwa umncinci, ilensi yokugxila inoluhlu oluthile lobunzulu befocal, ngoko inokwenza ukuskena okujolisa ngefomathi encinci. Nangona kunjalo, xa iplane eza kuskenwa inkulu, amanqaku akufutshane nomda aya kuba ngaphandle kokugxila kwaye awanakugxilwa kumphezulu we-workpiece eza kucutshungulwa kuba udlula imida ephezulu nesezantsi yobunzulu be-laser focal. Ke ngoko, xa umqadi welaser kufuneka ugxilwe kakuhle kuyo nayiphi na indawo kwiplane yokuskena kwaye intsimi yombono inkulu, ukusetyenziswa kwelensi yobude befocal ezinzileyo akunakuhlangabezana neemfuno zokuskena.

Inkqubo yokugxila eguqukayo yinkqubo yokujonga enobude bayo obungatshintshwa njengoko kufuneka. Ke ngoko, ngokusebenzisa ilensi yokugxila eguqukayo ukuhlawula umahluko wendlela yokukhanya, ilensi egobileyo (i-beam expander) ihamba ngokuthe ngqo ecaleni kwe-optical axis ukulawula indawo yokugxila, ngaloo ndlela ifezekisa imbuyekezo eguqukayo yomahluko wendlela yokukhanya yomphezulu oza kucutshungulwa kwiindawo ezahlukeneyo. Xa kuthelekiswa ne-2D galvanometer, ulwakhiwo lwe-3D galvanometer longeza ikakhulu "inkqubo yokukhanya ye-Z-axis", evumela i-3D galvanometer ukuba itshintshe ngokukhululekileyo indawo yokugxila ngexesha lenkqubo yokudibanisa kwaye yenze i-spatial curved surface welding, ngaphandle kwesidingo sokulungisa indawo yokugxila yokudibanisa ngokutshintsha ukuphakama kwenkampani efana nesixhobo somatshini okanye irobhothi efana ne-2D galvanometer.

Inkqubo yokugxila enamandla inokutshintsha ubungakanani be-defocus, itshintshe ubungakanani bendawo, ifezekise uhlengahlengiso lwe-Z-axis focus, kunye nokucutshungulwa kwemilinganiselo emithathu.

Umgama wokusebenza uchazwa njengomgama ukusuka kumda ongaphambili welensi ukuya kwi-focal plane okanye kwi-scan plane yenjongo. Lumka ungadibanisi oku nobude be-focal obusebenzayo (EFL) benjongo. Oku kulinganiswa ukusuka kwi-principal plane, i-hypothetical plane apho yonke inkqubo yelensi ithathwa njenge-refract, ukuya kwi-focal plane yenkqubo ye-optical.
