Abantu bavame ukubheka ukumaka nge-laser nokuqoshwa kwe-laser kuyinto efanayo. Eqinisweni, zihluke kancane.
Nakuba kokubili ukumaka nge-laser nokuqoshwa kwe-laser kusebenzisa i-laser ukushiya amamaki angenakusuleleka ezintweni. Kodwa ukuqoshwa nge-laser kwenza izinto zihwamuke kuyilapho ukumaka nge-laser kwenza izinto zincibilike. Indawo encibilikayo izonwetshwa futhi yakhe ingxenye yomsele engu-80µm ukujula, ezoshintsha ukushuba kwento futhi yakhe ukugqama okumnyama nokumhlophe. Ngezansi sizoxoxa ngezinto ezithinta umehluko omnyama nomhlophe ekumaka nge-laser.
Izinyathelo ezi-3 zokumaka nge-laser(1) Isinyathelo 1: I-laser beam isebenza endaweni ebonakalayo
Lokho ukumakwa kwe-laser nokuqoshwa kwe-laser kokubili okwabelana ngakho ukuthi ugongolo lwe-laser luyi-pulse. Okusho ukuthi, uhlelo lwe-laser luzofaka ukushaya kwenhliziyo ngemva kwesikhashana esithile. I-laser engu-100W ingafaka i-pulse engu-100000 njalo ngomzuzwana. Ngakho-ke, singabala ukuthi amandla okushaya okukodwa ngu-1mJ futhi inani eliphakeme lingafinyelela ku-10KW.
Ukuze ulawule amandla e-laser asebenza ezintweni, kuyadingeka ukulungisa amapharamitha we-laser. Futhi amapharamitha abaluleke kakhulu isivinini sokuskena nebanga lokuskena, ngoba lezi ezimbili zinquma isikhawu sama-pulses amabili aseduze asebenza kumpahla. Lapho ukusondela kwesikhawu sokushaya kwenhliziyo okuseduze, amandla azomuncwa engeziwe.
Uma kuqhathaniswa nokuqoshwa kwe-laser, ukumaka nge-laser kudinga amandla amancane, ngakho-ke ijubane lakho lokuskena liyashesha. Lapho unquma ukukhetha ukuthi i-laser engraving noma i-laser marking, isivinini sokuskena siyipharamitha enqumayo.
(2) Isinyathelo sesi-2: Impahla imunca amandla e-laser
Lapho i-laser isebenza endaweni ebonakalayo, amandla amaningi e-laser azobonakala endaweni ebonakalayo. Ingxenye encane kuphela yamandla e-laser amuncwa izinto bese iphenduka ukushisa. Ukuze wenze izinto zihwamuke, ukuqoshwa kwe-laser kudinga amandla engeziwe, kodwa ukumaka nge-laser kudinga amandla amancane kuphela ukuncibilikisa izinto.
Uma amandla amuncwa aphenduka abe ukushisa, izinga lokushisa lempahla lizokhula. Uma ifika endaweni yokuncibilika, indawo ebonakalayo izoncibilika yenze ushintsho.
Nge-laser ye-wavelength engu-1064mm, inesilinganiso sokumuncwa se-aluminium esilinganiselwa ku-5% kanye nangaphezulu kuka-30% wensimbi. Lokhu kwenza abantu bacabange ukuthi insimbi kulula ukumakwa nge-laser. Kodwa akunjalo. Kudingeka futhi sicabange ngezinye izinhlamvu ezibonakalayo zezinto zokwakha, njengendawo yokuncibilika.
(3) Isinyathelo sesi-3: Indawo ebonakalayo izoba nokunwebeka kwendawo kanye nokushintsha kokuqina.
Lapho okokusebenza kuncibilika futhi kuphola ngama-millisecond ambalwa, ukuhwaqana kwendawo ebonakalayo kuzoshintsha kwakhe ukumaka unomphela okuhlanganisa inombolo ye-serial, umumo, ilogo, njll..
Ukumaka amaphethini ahlukene endaweni ebonakalayo kuzoholela ekushintsheni kombala. Ukuze uthole ukumakwa kwe-laser yekhwalithi ephezulu, ukugqama okumnyama nokumhlophe kuyizinga lokuhlola elingcono kakhulu.
Uma indawo yempahla emagebhugebhu inokukhanya okusabalalisayo kokukhanya kwesigameko, indawo ebonakalayo izobonakala imhlophe;
Lapho into engaphezulu idonsa ukukhanya okuningi kwesigameko, indawo ebonakalayo izobonakala imnyama.
Ngenkathi kuqoshwa nge-laser, i-high density laser pulse isebenza endaweni ebonakalayo. Amandla e-laser aphenduka abe ukushisa, aguqule i-material isuke esimweni esiqinile iye esimweni segesi ukuze kukhishwe indawo engaphezulu.
Ngakho khetha ukumaka laser noma laser engraving?Ngemuva kokwazi umehluko phakathi kokumaka nge-laser nokuqoshwa kwe-laser, into elandelayo okufanele uyicabangele ukunquma ukuthi iyiphi ongayikhetha. Futhi kudingeka sicabangele izici ezi-3.
1.Ukumelana nemihuzuko
Umbhalo we-laser unokungena okujulile kunokumaka nge-laser. Ngakho-ke, uma ucezu lomsebenzi ludinga ukusetshenziswa endaweni ebandakanya ukuhuzuka noma okudinga ukucutshungulwa kokuthunyelwe njengokuqhumisa okulimazayo noma ukwelashwa kokushisa, kuyanconywa ukusebenzisa umbhalo we-laser.
2.Ijubane lokucubungula
Uma kuqhathaniswa nokuqoshwa kwe-laser, ukumaka nge-laser kunokungena okujulile, ngakho-ke isivinini sokucubungula siphezulu. Uma indawo yokusebenza lapho ucezu lomsebenzi lusetshenziswa khona lungabandakanyi ukuhuzuka, kutuswa ukusebenzisa ukumaka nge-laser.
3.Ukuvumelana
Ukumaka nge-laser kuzoncibilikisa okokusebenza ukuze kwakhe izingxenye ezincane ezingalingani kuyilapho ukuqoshwa nge-laser kuzokwenza izinto zihwamuke zenze umsele. Njengoba ukuqoshwa kwe-laser kudinga amandla anele e-laser ukwenza okokusebenza kufinyelele izinga lokushisa le-sublimation bese kuhwamuka ngama-millisecond ambalwa, ukuqoshwa kwe-laser ngeke kubonakale kuzo zonke izinto.
Kusukela ekucaciseni okungenhla, sikholwa ukuthi manje usunokuqonda kangcono ukuqoshwa kwe-laser nokumaka nge-laser.
