Iskena selaser, esikwabizwa ngokuba yi-laser galvanometer, siqulathe intloko yokuskena ye-XY optical, i-electronic drive amplifier kunye nelensi yokubonakalisa i-optical. Isignali enikezelwa ngumlawuli wekhompyutha iqhuba intloko yokuskena ye-optical kwisekethe ye-amplifier yokuqhuba, ngaloo ndlela ilawula ukuphambuka komqadi welaser kwiplane ye-XY. Ngokulula nje, i-galvanometer yi-scan galvanometer esetyenziswa kushishino lwelaser. Igama layo lobungcali libizwa ngokuba yi-high-speed scanning galvanometer Inkqubo yokuskena yeGalvo. I-galvanometer ebizwa ngokuba yi-ammeter nayo ingabizwa ngokuba yi-ammeter. Ingcamango yayo yoyilo ilandela ngokupheleleyo indlela yoyilo lwe-ammeter. Ilensi ithatha indawo yenaliti, kwaye isignali yeprobe ithatyathelwa indawo yisignali ye-DC elawulwa yikhompyutha -5V-5V okanye -10V-+10V. , ukuze kugqitywe isenzo esimiselweyo. Njengenkqubo yokuskena yesipili esijikelezayo, le nkqubo yolawulo eqhelekileyo isebenzisa izibuko ezimbini ezirhoxayo. Umahluko kukuba i-stepper motor eqhuba le seti yeelensi ithatyathelwa indawo yi-servo motor. Kule nkqubo yokulawula, kusetyenziswa i-position sensor. Uyilo lwe-negative feedback loop luqinisekisa ngakumbi ukuchaneka kwenkqubo, kwaye isantya sokuskena kunye nokuchaneka kokubekwa okuphindaphindiweyo kwenkqubo yonke kufikelela kwinqanaba elitsha. Intloko yokumakisha i-galvanometer yenziwe ikakhulu yi-XY scanning mirror, ilensi yasendle, i-galvanometer kunye nesoftware yokumakisha elawulwa yikhompyutha. Khetha izinto ezibonakalayo ezihambelanayo ngokwee-laser wavelengths ezahlukeneyo. Iinketho ezinxulumene nazo ziquka izandisi ze-laser beam, ii-laser, njl. Kwinkqubo yokubonisa i-laser, i-waveform ye-optical scanning yi-vector scan, kwaye isantya sokuskena senkqubo simisela uzinzo lwe-laser pattern. Kwiminyaka yakutshanje, kuye kwaphuhliswa ii-scanners ezinesantya esiphezulu, ngesantya sokuskena esifikelela kuma-45,000 amanqaku/isekondi, okwenza kube nokwenzeka ukubonisa ii-animations ze-laser ezintsonkothileyo.
5.1 Ijoyinti yokuwelda ye-laser galvanometer
5.1.1 Inkcazelo kunye nokwakheka kwejoyinti yokuwelda ye-galvanometer:
Intloko egxile kwi-collimation isebenzisa isixhobo soomatshini njengeqonga elixhasayo. Isixhobo soomatshini sihambahamba siye phambili nangasemva ukuze sifezekise ukuwelda kwee-welds ezahlukeneyo ze-trajectory. Ukuchaneka kokuwelda kuxhomekeke ekuchanekeni kwe-actuator, ngoko ke kukho iingxaki ezinje ngokuchaneka okuphantsi, isantya sokuphendula esicothayo, kunye ne-inertia enkulu. Inkqubo yokuskena ye-galvanometer isebenzisa i-motor ukuthwala ilensi ukuze iphambukise. I-motor iqhutywa ngumbane othile kwaye ineenzuzo zokuchaneka okuphezulu, i-inertia encinci, kunye nempendulo ekhawulezayo. Xa i-beam ikhanyiswa kwi-lens ye-galvanometer, ukuphambuka kwe-galvanometer kutshintsha i-laser beam. Ke ngoko, i-laser beam inokuskena nayiphi na i-trajectory kwindawo yokuskena yokujonga ngenkqubo ye-galvanometer.
Izinto eziphambili zenkqubo yokuskena ye-galvanometer yi-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-servo motors ze-X kunye ne-Y-axis. Ngale ndlela, ngentshukumo edibeneyo yelensi yesibuko ye-XY two-axis, inkqubo yolawulo inokuguqula isignali ngebhodi ye-galvanometer ngokwetemplate yemizobo emiselweyo yesoftware yekhompyutha yomsingathi ngokwendlela emiselweyo, kwaye ihambe ngokukhawuleza kwiplani yomsebenzi ukuze yenze indlela yokuskena.
5.1.2 Uhlu lwee-galvanometer welding joints:
1. Ilensi yokuskena egxile ngaphambili
Ngokwendlela ekwakhiwe ngayo phakathi kwelensi yokugxila kunye ne-laser galvanometer, indlela yokuskena ye-galvanometer inokwahlulwa ibe yi-front focusing scanning (Umfanekiso 1 ngezantsi) kunye ne-rear focusing focusing scanning (Umfanekiso 2 ngezantsi). Ngenxa yokubakho komahluko kwindlela ye-optical xa umqadi we-laser ujikelwe kwiindawo ezahlukeneyo (umgama wokudluliselwa komqadi wahlukile), umphezulu we-laser focal ngexesha lenkqubo yokuskena yangaphambili ye-focus mode yi-hemispherical surface, njengoko kubonisiwe kumfanekiso wasekhohlo. Indlela yokuskena emva kokugxila iboniswe kumfanekiso ongasekunene. Ilensi ejolise kuyo yilensi ye-F-plan. Isibuko se-F-plan sinoyilo olukhethekileyo lwe-optical. Ngokwazisa ukulungiswa kwe-optical, umphezulu we-hemispherical focal we-laser beam unokulungiswa ube yi-flat. I-Post-focus scanning ifanelekile kakhulu kwizicelo ezifuna ukuchaneka okuphezulu kokucubungula kunye noluhlu oluncinci lokucubungula, njengokuphawula nge-laser, i-laser microstructure welding, njl.
2.Ilensi yokuskena egxile ngasemva
Njengoko indawo yokuskena isanda, umngxuma welensi ye-f-theta nawo uyanda. Ngenxa yemida yobuchwephesha kunye nezinto ezibonakalayo, iilensi ze-f-theta ezinkulu zibiza kakhulu kwaye esi sisombululo asamkelwa. Inkqubo yokuskena ye-galvanometer yangaphambili yelensi ejolise ngqo kunye nerobhothi ene-axis ezintandathu sisisombululo esinokwenzeka, esinokunciphisa ukuxhomekeka kwizixhobo ze-galvanometer, sinomlinganiselo omkhulu wokuchaneka kwenkqubo, kwaye sinokuhambelana okuhle. Esi sisombululo samkelwe ziintegrators ezininzi. I-Adopt, edla ngokubizwa ngokuba yi-flight welding. I-welding ye-module busbar, kubandakanya ukucoca iipali, inezicelo zokubhabha, ezinokunyusa ububanzi bokucubungula ngokuguquguquka nangokufanelekileyo.
I-galvanometer ye-3.3D:
Nokuba kukuskena okujoliswe phambili okanye ukuskena okujoliswe ngasemva, ugxininiso lomqadi welaser alunakulawulwa ukuze kugxilwe ngokuguquguqukayo. Kwimo yokuskena okujoliswe phambili, xa umsebenzi oza kucutshungulwa umncinci, ilensi yokugxila inoluhlu oluthile lobunzulu obugxile, ngoko inokwenza ukuskena okugxileyo ngefomathi encinci. Nangona kunjalo, xa iplane eza kuskenwa inkulu, amanqaku akufutshane nomda aya kuba ngaphandle kokugxila kwaye awanakugxilwa kumphezulu weplane oza kucutshungulwa kuba udlula uluhlu lobunzulu bokugxila kwelaser. Ke ngoko, xa umqadi welaser kufuneka ugxilwe kakuhle kuyo nayiphi na indawo kwiplane yokuskena kwaye intsimi yombono inkulu, ukusetyenziswa kwelensi yobude obugxileyo obuzinzileyo akunakuhlangabezana neemfuno zokuskena. Inkqubo yokugxila ngokuguquguqukayo yiseti yeenkqubo ze-optical ezinobude obugxileyo obunokutshintsha njengoko kufuneka. Ke ngoko, abaphandi bacebisa ukusebenzisa ilensi yokugxila ngokuguquguqukayo ukuhlawula umahluko wendlela yokukhanya, kwaye basebenzise ilensi egobileyo (i-beam expander) ukuhamba ngokuthe ngqo kwi-axis yokukhanya ukulawula indawo yokugxila kunye nokufezekisa Umphezulu oza kucutshungulwa ngokuguquguqukayo uhlawula umahluko wendlela yokukhanya kwiindawo ezahlukeneyo. Xa kuthelekiswa ne-galvanometer ye-2D, ukwakheka kwe-galvanometer ye-3D kongeza ikakhulu "inkqubo ye-optical ye-Z-axis", ukuze i-galvanometer ye-3D ikwazi ukutshintsha ngokukhululekileyo indawo yokugxila ngexesha lenkqubo yokuxhuma kwaye yenze i-spatial curved surface welding, ngaphandle kwesidingo sokutshintsha i-carrier efana nesixhobo somatshini, njl.njl. njenge-galvanometer ye-2D. Ukuphakama kwerobhothi kusetyenziswa ukulungisa indawo yokugxila yokuxhuma.
