Ukuwelda kweLaserindlela yokugxila
Xa i-laser idibana nesixhobo esitsha okanye yenza umfuniselo omtsha, inyathelo lokuqala kufuneka lijolise. Kuphela ngokufumana inqwelo-moya egxininisekileyo apho ezinye iiparameters zenkqubo ezifana ne-defocusing amount, amandla, isantya, njl. njl. zimiselwe ngokuchanekileyo, ukuze ube nokuqonda okucacileyo.
Umgaqo wokujolisa ngolu hlobo lulandelayo:
Okokuqala, amandla e-laser beam awasasazwanga ngokulinganayo. Ngenxa yesimo se-hourglass kwicala lasekhohlo nasekunene lesibuko esigxininisayo, amandla agxininiswe kakhulu kwaye anamandla kwindawo yesinqe. Ukuqinisekisa ukusebenza kakuhle kunye nomgangatho, ngokuqhelekileyo kuyimfuneko ukufumana indawo yenqwelomoya kwaye ulungelelanise umgama wokungagxininisi ngokusekelwe kule mveliso. Ukuba akukho nqwelo-moya ekugxilwe kuyo, iiparamitha ezilandelayo aziyi kuxoxwa, kwaye ukulungisa isixhobo esitsha kufuneka kwakhona kuqale kumisele ukuba inqwelo-moya ekugxilwe kuyo ichanekile. Ke ngoko, ukufumana indawo yenqwelomoya sisifundo sokuqala kwitekhnoloji yelaser.
Njengoko kubonisiwe kwiMifanekiso 1 kunye ne-2, iimpawu zobunzulu be-laser beams kunye namandla ahlukeneyo ahlukeneyo, kwaye i-galvanometers kunye nemowudi enye kunye ne-laser ye-multimode nayo yahlukile, ibonakaliswe ngokuyinhloko ekuhanjisweni kwendawo yezakhono. Ezinye zibuthelene ngokwentelekiso, ngoxa ezinye zibhityile ngokwentelekiso. Ke ngoko, kukho iindlela ezahlukeneyo zokugxila kwimiqadi yelaser eyahlukeneyo, eyohlulwe ngokubanzi yangamanyathelo amathathu.

Umzobo 2 Umzobo weskim sobunzulu bengqwalasela kumagunya ahlukeneyo
Isikhokelo sobungakanani bendawo kwimigama eyahlukeneyo
Indlela yokuSlanting:
1. Okokuqala, misela uqikelelo loluhlu lwenqwelo-moya egxininisekileyo ngokukhokela indawo yokukhanya, kwaye umisele eyona ndawo iqaqambileyo nencinane yendawo yokukhanya esisikhokelo njengojoliso lovavanyo lokuqala;
2. Ukwakhiwa kweqonga, njengoko kubonisiwe kuMfanekiso 4
Umzobo we-4 Umzobo weSchematic wezixhobo ezigxininisiweyo zomgca oblique
2. Izilumkiso ze-diagonal strokes
(1) Ngokuqhelekileyo, iipleyiti zetsimbi zisetyenziswa, kunye ne-semiconductors ngaphakathi kwe-500W kunye ne-optical fibers malunga ne-300W; Isantya sinokumiselwa kwi-80-200mm
(2) Okukhona i-engile ethambekileyo yepleyiti yentsimbi, kungcono, zama ukuba malunga nama-45-60 degrees, kwaye usete indawo esembindini kwindawo erhabaxa ekugxilwe kuyo ngeyona ndawo incinci kunye neyona iqaqambayo yokukhanya;
(3) Emva koko qalisa intambo, yintoni ephunyezwa yintambo? Kwithiyori, lo mgca uya kusasazwa ngokulinganayo malunga nendawo ekugxilwe kuyo, kwaye i-trajectory iya kuhamba kwinkqubo yokunyuka ukusuka kwinkulu ukuya kwincinci, okanye ukunyuka ukusuka kwincinci ukuya enkulu kwaye emva koko iyancipha;
(4) I-semiconductors ifumana eyona ndawo incinci, kwaye ipleyiti yentsimbi iya kujika ibe mhlophe kwindawo egxininise kuyo kunye neempawu ezicacileyo zombala, ezinokuthi zisebenze njengesiseko sokufumana indawo ekugxilwe kuyo;
(5) Okwesibini, i-fiber optic kufuneka izame ukulawula ukungena kwe-micro ngasemva kangangoko kunokwenzeka, kunye nokungena kwe-micro kwindawo ekugxilwe kuyo, ebonisa ukuba indawo ekugxilwe kuyo iphakathi kobude bokungena kwe-micro yangasemva. Ngeli nqanaba, ukubekwa kwe-coarse ye-focal point kugqityiwe, kwaye i-laser encediswayo yomgca isetyenziselwa inyathelo elilandelayo.

3. Isinyathelo esilandelayo kukulinganisa i-workpiece, ukulungelelanisa i-laser yomgca ukuba ihambelane nokugxilwa ngenxa yendawo yesikhokelo sokukhanya, ekugxilwe kuyo, kwaye emva koko wenze ungqinisiso lokugqibela lwendiza.
(1) Ukuqinisekiswa kuqhutyelwa ngokusetyenziswa kwamanqaku e-pulse. Umgaqo-siseko kukuba iintlantsi zisasazwa kwindawo ekugxilwe kuyo, kwaye iimpawu zesandi zicacile. Kukho umda womda phakathi kwemida ephezulu nangaphantsi yendawo ekugxilwe kuyo, apho isandi sihluke kakhulu kwi-splashes kunye neentlantsi. Rekhoda imida ephezulu kunye nesezantsi yendawo ekugxilwe kuyo, kwaye indawo ephakathi yindawo ekugxilwe kuyo,
(2) Lungisa i-laser yomgca i-overlap kwakhona, kwaye ugxininiso sele lubekwe ngempazamo malunga ne-1mm. Ingaphinda-phinda indawo yovavanyo ukuphucula ukuchaneka.
Umzobo we-6 Umboniso we-Spark Splash kwimigama eyohlukeneyo yokuSebenza (Isixa sokuJonga)
Umzobo 7 Umzobo weSchematic of pulse dotting and focusing
Kukwakho nendlela yokuchaphaza: ilungele iilaser zefiber ezinobunzulu obugxininise obukhulu kunye notshintsho olubalulekileyo kubungakanani bendawo kwicala le-Z-axis. Ngokucofa umqolo wamachaphaza ukujonga imeko yotshintsho kumanqaku angaphezulu kwipleyiti yentsimbi, ngalo lonke ixesha i-Z-axis itshintsha nge-1mm, ushicilelo kwipleyiti yentsimbi lutshintsha ukusuka kwenkulu ukuya kwencinci, emva koko ukusuka kwincinci ukuya kwi-axis. enkulu. Eyona ndawo incinci yindawo ekugxilwe kuyo.
