Iintloko egxile kwi-collimationinokwahlulwa ibe ziintloko zokuwelda ezinamandla aphezulu kunye neziphakathi eziphantsi ngokwemeko yesicelo, umahluko ophambili uyinto yelensi kunye nokwaleka. Iziganeko ezibonisiweyo ikakhulu kukushukuma kobushushu (ukushukuma kobushushu obuphezulu) kunye nokulahleka kwamandla. Intloko eqokelelanayo negxilayo eneshukuma esihle sobushushu ingalawulwa ngaphakathi kwe-1mm; Phantse idlule kwi-2mm; Ukulahleka kwamandla ikakhulu kubhekisa ekulahlekelweni kwamandla okubangelwa yilaser engena kwintloko yokuwelda esuka kwintloko ye-QBH ize ikhusele ilensi ngaphantsi. Amandla aphambili aguqulwa abe kukufudumala kwelensi, okuhlala kufuna ngaphantsi kwe-3%, amanye anokufikelela kwi-1%, kwaye amanye anokudlula kwi-5%. Ke ngoko, ezi zimbini ziyimpawu eziphambili zeentloko eziqokelelanayo nezigxilayo. Kungcono ukuzilinganisa ngokwakho ngaphambi kokusebenzisa okanye ucele umenzi ukuba anike iingxelo ezifanelekileyo ukuqinisekisa ukuba imveliso iyahlangabezana neemfuno zemveliso yemizi-mveliso kwindawo.
Ukwahlulwahlulwa kweentloko ezigxile kwi-collimated focus - ukwahlulwahlulwa okusebenzayo
Ngokubhekiselele ekubeni inomsebenzi wokujika okanye wokujika, nokuba sisipili esinye okanye esiphindwe kabini, inokwahlulwa ibe yintloko eqhelekileyo ye-collimating ne-focussive, intloko ye-single pendulum, kunye nentloko ye-double pendulum. Ijolise kakhulu kwiimfuno ezahlukeneyo zescene, kwaye indlela ye-double pendulum iya kuba nzima ngakumbi kunaleyo ye-single pendulum.
Ngokwendlela ehambelana ngayoinkqubo yelaser, ingahlulwa ibe: (1) intloko edibeneyo yebhendi ezimbini (obomvu okwesibhakabhaka, i-fiber semiconductor, njl.njl.), (2) intloko edibeneyo yokujikeleza (ukujikeleza okukodwa), kunye nentloko ye-point loop.
(3)Intloko yokwelulela indandatho yePoint luhlobo olutsha lwentloko yokwelulela enokwakha imisebe yelaser enamandla aphezulu ibe yimilo yesangqa okanye yesangqa se-point ring ngokusebenzisa ukubumba imisebe, ukulinganisela ukusasazwa kwamandla. Ivakala ifana nokuguqula iilaser ezinamandla aphezulu zibe ngamabala okukhanya ajikelezayo, kodwa yahlukile. Xa kuthelekiswa nemilo yesangqa, amandla asembindini weentloko zesangqa se-point ring awanelanga kwaye amandla azo okungena anqongophele. Nangona kunjalo, le ndlela ilula yokufikelela kusasazo lwamandla elaser afana namabala okukhanya ajikelezayo ngeentloko zesangqa se-point ring inokufezekisa isiphumo esingabizi kakhulu nesiphantsi sokutshiza. Kwi-welding yentsimbi, inenzuzo ekhethekileyo yegesi. Ngenxa yokwanda kwamabala okukhanya kunye nokufana kobuninzi bamandla, inokuba sengozini yokwelulela okungamanga kwizinto ezibonisa ukukhanya okuphezulu (i-aluminium, ithusi).
Ilensi yokugxila ehlanganisiweyo
Kwiilensi ezisetyenziswa kwiinkqubo zokudlulisa i-laser, izinto zazo zinokwahlulwa zibe ziintlobo ezimbini: izinto ezidluliselwayo kunye nezinto ezibonisa ukukhanya; Ilensi egxilayo kunye nelensi ekhuselayo kufuneka yenziwe ngezinto ezidlulisela ukukhanya. Iimfuno: izinto kufuneka zibe nokudluliselwa okuhle kwibhendi yamaza asebenzayo, ubushushu obuphezulu bokusebenza kunye ne-coefficient ephantsi yokwandiswa kobushushu. Ngokubanzi, ilensi egxilayo kufuneka yenziwe nge-silica edibeneyo; Ilensi ekhuselayo yenziwe ngezinto ezibonisa ukukhanya, ngokuqhelekileyo iglasi ye-K9. Izinto ezibonisa ukukhanya zenziwe ngokugubungela ifilimu encinci yezinto zesinyithi ezibonisa ukukhanya okuphezulu kwiglasi ekhazimlisiweyo okanye kumphezulu wesinyithi, kwaye ukubonakalisa ukukhanya akunazo iindawo ezisasazekayo. Ke ngoko, uphawu olulodwa lokukhanya lwezinto ezibonisa ukukhanya kukubonakalisa ukukhanya kwazo kwemibala eyahlukeneyo yokukhanya. Iimfuno zezinto ezibonisa ukukhanya kwiilensi ezibonisa ukukhanya zezi: 1. Ukukhanya okuzinzileyo kokukhanya; 2. Ukuqhuba okuphezulu kobushushu; 3. Indawo yokunyibilika ephezulu; Ngale ndlela, nokuba kukho ukungcola kumaleko wokugubungela, ukufunxwa kobushushu okugqithisileyo akuyi kubangela ukuqhekeka okanye ukutsha.
Ukudibanisa i-collimation kunye nokugxila kuchaphazela ubukhulu bebala: Ubungakanani bebala le-laser beam yiparameter ebalulekileyo echaphazela umgangatho we-scanning welding, ingakumbi ubungakanani bebala elijoliswe kumphezulu we-workpiece buchaphazela ngokuthe ngqo uxinano lwamandla e-laser beam. Xa amandla e-scanning laser engaguqukiyo, ubungakanani bebala obuncinci bunokufikelela kuxinano lwamandla aphezulu, oluluncedo kwi-welding high melting point kunye nobunzima bokunyibilikisa iintsimbi. Kwangaxeshanye, inokufumana umlinganiselo omkhulu kwaye ihlangabezane neemfuno ezithile ze-welding ezikhethekileyo. Xa indawo yokunyibilika kwezinto ezisisiseko se-welding iphantsi, okanye xa kukho umsantsa othile phakathi kweepleyiti ezimbini ngexesha le-welding, ubungakanani bebala elikhulu budla ngokukhethwa ukuze kufezekiswe iziphumo ezingcono ze-welding.
Ubude be-collimation focal ubude buphakathi kwe-80-150mm, kwaye ubude be-focal focal ngokubanzi buphakathi kwe-100-300mm,; Oku kuxhomekeke kakhulu kumgama wokucubungula kunye nobukhulu bebala (ubuninzi bamandla), kunye nokunyamezela kwendawo ukuya kumsantsa we-weld seam (ukuba indawo incinci kakhulu, umsantsa uya kuvuza ukukhanya ukuba mkhulu kakhulu, kwaye umsantsa ngokubanzi awudluli kwi-30% yobubanzi bebala).
Uvavanyo lokujonga intloko egxile kwi-collimating ngaphambi kokusetyenziswa: uvavanyo lokudlulisela; Uvavanyo lokushukuma kobushushu
