Mutu wolunjika wophatikizana umagwiritsa ntchito chida chamakina ngati nsanja yothandizira, ndipo umayenda mmbuyo ndi mtsogolo kudzera mu chipangizo cha makina kuti akwaniritse kuwotcherera kwa ma weld okhala ndi ma trajectories osiyanasiyana. Kulondola kwa kuwotcherera kumadalira kulondola kwa actuator, kotero pali mavuto monga kulondola kochepa, kuthamanga kwapang'onopang'ono, ndi inertia yaikulu. Makina ojambulira a galvanometer amagwiritsa ntchito mota kupotoza mandala. Galimotoyo imayendetsedwa ndi mphamvu inayake ndipo ili ndi ubwino wolondola kwambiri, inertia yaying'ono, komanso kuyankha mofulumira. Pamene kuwala kwa kuwala kwawunikira pa lens ya galvanometer, kupotoza kwa galvanometer kumasintha mawonekedwe a kuwala kwa laser. Chifukwa chake, mtengo wa laser ukhoza kuyang'ana njira iliyonse pazithunzi zowonera kudzera pa galvanometer system. Mutu woyimirira womwe umagwiritsidwa ntchito mu robotic welding system ndi ntchito yotengera mfundo iyi.
Zigawo zikuluzikulu zagalvanometer sikani dongosolondi collimator yokulitsa, yoyang'ana magalasi, XY-axis scanning galvanometer, board board ndi pulogalamu yamapulogalamu apakompyuta. Galvanometer yojambulira imatanthawuza mitu iwiri ya XY galvanometer, yomwe imayendetsedwa ndi ma servo motors othamanga kwambiri. Dongosolo la servo lapawiri-axis limayendetsa XY dual-axis scanning galvanometer kuti apatuke motsatira X-axis ndi Y-axis motsatana potumiza ma siginecha amalamulo ku X ndi Y axis servo motors. Mwa njira imeneyi, kudzera ophatikizana kayendedwe ka XY awiri olamulira galasi mandala, dongosolo ulamuliro akhoza kusintha chizindikiro kudzera galvanometer bolodi molingana ndi Chinsinsi cha preset zithunzi za khamu mapulogalamu apakompyuta ndi mode anapereka njira, ndipo mwamsanga kusuntha. pa ndege ya workpiece kupanga sikani trajectory.

Malinga ndi ubale wapakati pa lens yoyang'ana kwambiri ndi galvanometer ya laser, njira yojambulira ya galvanometer imatha kugawidwa kukhala kusanthula koyang'ana kutsogolo (chithunzi chakumanzere) ndi kusanthula kumbuyo (chithunzi chakumanja). Chifukwa cha kusiyana kwa njira ya kuwala pamene mtengo wa laser umapatukira kumalo osiyanasiyana (kutalika kwa mtengo wodutsa ndi kosiyana), ndege yoyang'ana ya laser yomwe idayang'ana m'mbuyomu ndi yopindika pamtunda, monga momwe tawonera kumanzere. Njira yoyang'ana kumbuyo ikuwonetsedwa mu chithunzi choyenera, momwe lens ya cholinga ndi lens ya flat field. The flat field lens ali ndi mawonekedwe apadera a kuwala.
Mwa kuyambitsa kuwongolera kwa kuwala, ndege ya hemispherical focal ya laser mtengo imatha kusinthidwa kukhala ndege. Back kuganizira kupanga sikani makamaka oyenera ntchito ndi mkulu processing olondola zofunika ndi ang'onoang'ono processing osiyanasiyana, monga laser chodetsa, laser microstructure kuwotcherera, etc. Pamene kupanga sikani m'dera ukuwonjezeka, kabowo wa mandala kumawonjezera. Chifukwa cha zolephera zaukadaulo ndi zakuthupi, mtengo wa ma flenses akulu ndi okwera mtengo kwambiri, ndipo yankho ili silivomerezedwa. Kuphatikiza kwa galvanometer scanning system kutsogolo kwa lens ya cholinga ndi loboti ya olamulira asanu ndi limodzi ndi njira yotheka yomwe ingachepetse kudalira zida za galvanometer, ndipo imatha kukhala ndi kulondola kwadongosolo komanso kuyanjana kwabwino. Njira yothetsera vutoli yatengedwa ndi ophatikiza ambiri, omwe nthawi zambiri amatchedwa flying welding. Kuwotcherera kwa module busbar, kuphatikizapo kuyeretsa kwa mzati, kumakhala ndi ntchito zowuluka, zomwe zingathe kusinthasintha komanso mogwira mtima kuonjezera mtundu wa processing.
Kaya ndikusanthula koyang'ana kutsogolo kapena kuyang'ana kumbuyo, chowunikira cha laser sichingawongoleredwe kuti chiziyang'ana kwambiri. Pamawonekedwe owunikira kutsogolo, chogwirira ntchito chikakhala chaching'ono, disolo loyang'ana kwambiri limakhala ndi kuzama kwakuya, kotero limatha kuchita sikanizoni ndi mawonekedwe ang'onoang'ono. Komabe, ndege yoti sikanidwe ikakhala yayikulu, mfundo zomwe zili pafupi ndi m'mphepete mwake sizikhala zowoneka bwino ndipo sizingayang'ane pamwamba pa chogwirira ntchito kuti chisinthidwe chifukwa chimaposa malire apamwamba ndi apansi akuzama kwa laser focal. Choncho, pamene mtengo wa laser uyenera kuyang'ana bwino pamalo aliwonse pa ndege yojambulira ndipo malo owonetserako ndi aakulu, kugwiritsa ntchito lens yokhazikika yokhazikika sikungakwaniritse zofunikira zowunikira.
Dongosolo loyang'ana kwambiri ndi mawonekedwe owoneka bwino omwe kutalika kwake kumatha kusinthidwa ngati pakufunika. Chifukwa chake, pogwiritsa ntchito mandala osunthika kuti athe kubweza kusiyana kwa njira ya kuwala, mandala a concave (beam expander) amayenda motsatira mbali ya optical axis kuti ayang'anire malo omwe akuyang'ana, motero amapeza chipukuta misozi cha kusiyana kwa njira ya pamwamba yomwe iyenera kukonzedwa. pa maudindo osiyanasiyana. Poyerekeza ndi 2D galvanometer, ndi 3D galvanometer zikuchokera makamaka anawonjezera "Z-olamulira kuwala dongosolo", amene amalola 3D galvanometer momasuka kusintha malo pa ndondomeko kuwotcherera ndi kuchita malo yokhota kumapeto kuwotcherera, popanda kusintha kuwotcherera. yang'anani posintha kutalika kwa chonyamulira monga chida cha makina kapena loboti ngati 2D galvanometer.
Dongosolo loyang'ana kwambiri limatha kusintha kuchuluka kwa defocus, kusintha kukula kwa malo, kuzindikira kusintha kwa Z-axis, ndikusintha katatu.
Mtunda wogwirira ntchito umatanthauzidwa ngati mtunda wochokera kutsogolo-kutsogolo kwamakina a mandala kupita ku ndege yolunjika kapena ndege yojambulira cholingacho. Samalani kuti musasokoneze izi ndi kutalika kwapakati (EFL) kwa cholinga. Izi zimayesedwa kuchokera ku ndege yaikulu, ndege yongopeka momwe dongosolo lonse la lens limaganiziridwa kuti limasintha, kupita kumalo ozungulira a optical system.
