Musoro wekutarisa we collimating unoshandisa mudziyo wemakanika sepuratifomu inotsigira, uye unofamba uchidzokera shure nepamuchina wemakanika kuti uwane welding ye welds dzine nzira dzakasiyana. Kururama kwe welding kunoenderana nekururama kwe actuator, saka pane matambudziko akadai sekururama kushoma, kumhanya kunonoka kwemhinduro, uye inertia huru. Sisitimu yekuongorora ye galvanometer inoshandisa mota kutsausa lenzi. Mota inofambiswa nemagetsi akati wandei uye ine zvakanakira zvekururama kwakanyanya, inertia diki, uye mhinduro nekukurumidza. Kana mwenje wechiedza wavhenekerwa pa lenzi ye galvanometer, kutsauka kwe galvanometer kunochinja kona yekuratidzira kwelaser beam. Naizvozvo, laser beam inogona kuskena chero nzira iri mu scanning field of view kuburikidza ne galvanometer system. Musoro wakamira unoshandiswa mu robotic welding system ishandiso yakavakirwa panheyo iyi.
Zvikamu zvikuru zvesisitimu yekuskena yegalvanometerndiwo beam expansion collimator, focusing lens, XY two-axis scanning galvanometer, control board uye host computer software system. Iyo scanning galvanometer inonyanya kureva maviri XY galvanometer scanning heads, ayo anofambiswa ne high-speed reciprocating servo motors. Iyo dual-axis servo system inotyaira XY dual-axis scanning galvanometer kuti itsauke ichitevedza X-axis neY-axis zvichiteerana nekutumira masaini emirairo kuma X neY axis servo motors. Nenzira iyi, kuburikidza nekufamba kwakabatana kweXY two-axis mirror lens, control system inogona kushandura chiratidzo kuburikidza negalvanometer board zvichienderana ne template ye preset graphics ye host computer software uye set path mode, uye nekukurumidza kufamba pa workpiece kuti igadzire scanning trajectory.

Zvichienderana nehukama huripo pakati pe lenzi yekutarisa ne laser galvanometer, nzira yekuskena ye galvanometer inogona kukamurwa kuita front focusing scanning (mufananidzo wekuruboshwe) uye back focusing scanning (mufananidzo wekurudyi). Nekuda kwekuvapo kwemusiyano wenzira ye optical apo laser beam inotsauka kuenda kunzvimbo dzakasiyana (daro rekutumira beam rakasiyana), laser focal plane mukuita kwekare kwe focusing scanning i hemispherical curved surface, sezvakaratidzwa mumufananidzo wekuruboshwe. Nzira yekuskena ye back focusing inoratidzwa mumufananidzo wekurudyi, umo objective lens iri flat field lens. Flat field lens ine dhizaini yakasarudzika ye optical.
Sisitimu Yekushongedza Yemarobhoti
Nekuisa optical correction, hemispherical focal plane yelaser beam inogona kugadziriswa kuti ive plane. Back focusing scanning inonyanya kukodzera maapplication ane high processing accuracy ne small processing range, akadai se laser marking, laser microstructure welding, nezvimwewo. Sezvo scanning area ichiwedzera, aperture yelens inowedzerawo. Nekuda kwezvipingamupinyi zvehunyanzvi uye zvezvinhu, mutengo we large-aperture flenses unodhura zvikuru, uye mhinduro iyi haigamuchirwi. Kusanganiswa kwe galvanometer scanning system pamberi pe objective lens ne six-axis robot imhinduro inogoneka inogona kuderedza kuvimba nemidziyo ye galvanometer, uye inogona kuva nedanho rakakura re system accuracy uye compatibility yakanaka. Mhinduro iyi yakagamuchirwa nevakawanda vanobatanidza, iyo inowanzonzi flying welding. Welding ye module busbar, kusanganisira kuchenesa pole, ine maapplication ekubhururuka, ayo anogona kuwedzera processing format nenzira inochinjika uye inobudirira.
Ingave iri front-focus scanning kana rear-focus scanning, focus yelaser beam haigone kudzorwa kuti ikwanise kutarisisa zvinhu zvine simba. Kune front-focus scanning mode, kana workpiece iri kutarisirwa kugadziriswa iri diki, focus lens ine focal depth range yakati, saka inogona kuita focus scanning ine format diki. Zvisinei, kana plane iri kutarisirwa scanning yakakura, nzvimbo dziri pedyo neperiphery hadzizove dzakananga uye hadzigone kunangidzirwa pamusoro peworkpiece iri kutarisirwa kugadziriswa nekuti inodarika miganhu yepamusoro neyapasi ye laser focal depth. Naizvozvo, kana laser beam ichidikanwa kuti itarisiswe zvakanaka panzvimbo ipi zvayo pa scanning plane uye field of view yakakura, kushandiswa kwe fixed focal length lens hakugone kusangana nezvinodiwa zve scanning.
Sisitimu yekutarisa inochinja-chinja isystem yekutarisa ine urefu hwayo hunogona kuchinjwa kana zvichidikanwa. Saka, nekushandisa lenzi yekutarisa inochinja-chinja kuti igadzirise musiyano wenzira yekutarisa, lenzi ye concave (beam expander) inofamba yakatevedzana ichitevedza axis yekutarisa kuti idzore nzvimbo yekutarisa, nokudaro ichiwana muripo unochinja-chinja wemusiyano wenzira yekutarisa pamusoro penzvimbo dzinofanira kugadziriswa panzvimbo dzakasiyana. Kana ichienzaniswa ne2D galvanometer, chimiro che3D galvanometer chinonyanya kuwedzera "Z-axis optical system", iyo inobvumira 3D galvanometer kuchinja nzvimbo yekutarisa zvakasununguka panguva yekubatanidza uye kuita welding yespatial curved surface, pasina chikonzero chekugadzirisa nzvimbo yekutarisa yekubatanidza nekuchinja kukwirira kwemutakuri senge chishandiso chemuchina kana robhoti senge2D galvanometer.
Sisitimu yekutarisa inochinja inogona kushandura huwandu hwe defocus, kushandura saizi yenzvimbo, kugadzirisa Z-axis focus, uye kugadzirisa kwemativi matatu.
Kureba kwekushanda kunotsanangurwa sedaro kubva kumucheto wepamberi welenzi kuenda kunhandare yekutarisa kana kuskena chinangwa. Chenjerera kuti usavhiringidze izvi nehukuru hwenzvimbo yekutarisa (EFL) hwechinangwa. Izvi zvinoyerwa kubva kunhandare huru, ndege inofungidzirwa kuti system yese yelenzi inoramba, kuenda kunhandare yekutarisa yesystem yekuona.
