Ukuwelda nge-laserindlela yokugxila
Xa i-laser idibana nesixhobo esitsha okanye isenza uvavanyo olutsha, inyathelo lokuqala kufuneka libe kukugxila. Kuphela kukufumana i-focal plane apho ezinye iiparameter zenkqubo ezifana nobungakanani bokungazinzisa, amandla, isantya, njl.njl. zinokumiselwa ngokuchanekileyo, ukuze kube nokuqonda okucacileyo.
Umgaqo wokugxila ngolu hlobo lulandelayo:
Okokuqala, amandla e-laser beam awasasazwa ngokulinganayo. Ngenxa yesimo se-hourglass kwicala lasekhohlo nelasekunene lesibuko esijolisa amehlo, amandla agxile kakhulu kwaye anamandla kwindawo yesinqe. Ukuqinisekisa ukusebenza kakuhle kunye nomgangatho wokucubungula, ngokubanzi kuyimfuneko ukufumana i-focal plane kunye nokulungisa umgama wokususa ukugxila ngokusekelwe koku ukuze kucutshungulwe imveliso. Ukuba akukho focal plane, iiparameter ezilandelayo aziyi kuxoxwa ngazo, kwaye ukulungisa iingxaki zezixhobo ezintsha kufuneka kuqala kuchonge ukuba i-focal plane ichanekile na. Ke ngoko, ukufumana i-focal plane sisifundo sokuqala kwitekhnoloji ye-laser.
Njengoko kubonisiwe kwiMifanekiso 1 kunye no-2, iimpawu zobunzulu be-focal beams ze-laser ezinamandla ahlukeneyo zahlukile, kwaye ii-galvanometers kunye nee-single mode kunye nee-multimode lasers nazo zahlukile, zibonakaliswa kakhulu kulwabiwo lwesithuba lwezakhono. Ezinye zincinci, ngelixa ezinye zincinci. Ke ngoko, kukho iindlela ezahlukeneyo zokugxila kwii-laser beams ezahlukeneyo, ezihlala zahlulwe zibe ngamanyathelo amathathu.
Umfanekiso 1 Umzobo weskimu wobunzulu beendawo ezahlukeneyo zokukhanya
Umfanekiso 2 Umzobo wesicwangciso sobunzulu befocal kumandla ahlukeneyo
Ubungakanani bendawo yesikhokelo kumgama owahlukeneyo
Indlela yokuthambekela:
1. Okokuqala, misela uluhlu oluqikelelweyo lwendiza ejolise ngqo ngokukhokela indawo yokukhanya, kwaye umisele indawo ekhanyayo neyona incinci kakhulu yendawo yokukhanya ekhokelayo njengengqwalasela yokuqala yovavanyo;
2. Ukwakhiwa kweqonga, njengoko kubonisiwe kuMfanekiso 4
Umfanekiso 4 Umzobo wesicwangciso sezixhobo zokugxila kumgca otyhidiweyo
2. Amanyathelo okuzikhusela xa kuthe kwavela imivumbo ethe tyaba
(1) Ngokubanzi, kusetyenziswa iipleyiti zentsimbi, ezinee-semiconductors ezingaphakathi kwe-500W kunye neefayibha ze-optical ezijikeleze i-300W; Isantya sinokumiselwa kwi-80-200mm
(2) Okukhona i-engile etyebileyo yepleyiti yentsimbi inkulu, kokukhona kungcono, zama ukuba malunga nama-45-60 degrees, uze ubeke i-midpoint kwindawo egxile kwindawo erhabaxa ene-light light encinci nekhanyayo;
(3) Emva koko qala ukufaka iintambo, yintoni isiphumo esifezekiswa yi-stringing? Ngokwethiyori, lo mgca uza kusasazwa ngokulinganayo ujikeleze indawo ephambili, kwaye indlela eya phambili iza kunyuka ukusuka kwinto enkulu ukuya kwencinci, okanye inyuke ukusuka kwinto encinci ukuya kwenkulu ize inciphe;
(4) Ii-semiconductors zifumana eyona ndawo incinci, kwaye ipleyiti yentsimbi iya kuba mhlophe kwindawo egxile kuyo eneempawu zombala ezicacileyo, ezinokuthi zisebenze njengesiseko sokufumana indawo egxile kuyo;
(5) Okwesibini, i-fiber optic kufuneka izame ukulawula ukungena kwe-micro ngasemva kangangoko kunokwenzeka, kunye nokungena kwe-micro kwindawo ephambili, okubonisa ukuba indawo ephambili iphakathi kobude bokungena kwe-micro ngasemva. Kule ndawo, indawo ebanzi yendawo ephambili igqityiwe, kwaye indawo encediswa yi-laser yomgca isetyenziselwa inyathelo elilandelayo.

3. Inyathelo elilandelayo kukulinganisa i-workpiece, ulungise i-laser yomgca ukuze ihambelane ne-focus ngenxa yendawo yesikhokelo sokukhanya, eyi-focus yokubeka indawo, uze wenze uqinisekiso lokugqibela lwe-focal plane
(1) Ukuqinisekiswa kwenziwa ngokusebenzisa amanqaku okubetha kwentliziyo. Umgaqo kukuba iintlantsi zitshizwe kwindawo egxile kuyo, kwaye iimpawu zesandi zicacile. Kukho indawo yomda phakathi kwemida ephezulu nesezantsi yendawo egxile kuyo, apho isandi sahluke kakhulu kwiintlantsi kunye neentlantsi. Bhala phantsi imida ephezulu nesezantsi yendawo egxile kuyo, kwaye indawo ephakathi yindawo egxile kuyo,
(2) Lungisa kwakhona i-line laser overlap, kwaye i-focus sele ibekwe kwindawo enempazamo emalunga ne-1mm. Ingaphinda indawo yovavanyo ukuphucula ukuchaneka.
Umfanekiso 6 Umboniso weSpark Splash kumgama owahlukileyo wokusebenza (Inani lokungajolisi)
Umfanekiso 7 Umzobo wesicwangciso see-pulse dots kunye ne-focus
Kukwakho nendlela yokuchaphaza: ifanelekile kwiilaser zefayibha ezinobunzulu obukhulu befocal kunye notshintsho olukhulu kubungakanani bamabala kwicala le-Z-axis. Ngokucofa umqolo wamachaphaza ukuze ubone indlela yokutshintsha kwamanqaku kumphezulu wepleyiti yentsimbi, ngalo lonke ixesha i-Z-axis itshintsha nge-1mm, uphawu olukwipleyiti yentsimbi luyatshintsha ukusuka kwenkulu ukuya kwencinci, emva koko ukusuka kwencinci ukuya kwenkulu. Ingongoma encinci yindawo egxile kuyo.
