Mayelana ne-Laser Marking

1.Kuyini ukumaka nge-laser?

Ukumaka nge-laser kusebenzisa i-laser beam ukumaka unomphela ingaphezulu lezinto ezahlukahlukene.Umthelela wokumaka uwukuveza izinto ezijulile ngokuhwamuka kwezinto ezingaphezulu, noma “uqopha” imikhondo ngokusebenzisa amakhemikhali nokomzimba wento engaphezulu ebangelwa amandla okukhanya, noma ukushisa ingxenye yento ngokusebenzisa amandla okukhanya. ukukhombisa ukumaka okudingekayo.Amaphethini we-Eclipse nombhalo.

2.Isimiso sokusebenza kanye nezinzuzo zomshini wokumaka we-laser

Ukuphrinta kokumaka nge-laser kubuye kubizwe ngokumaka nge-laser kanye nomaka we-laser.Eminyakeni yamuva nje, iye yasetshenziswa kakhulu emkhakheni wokunyathelisa, njengokunyathelisa amaphakethe, ukunyathelisa izikweletu, nokunyathelisa amalebula okulwa nokukhwabanisa.Ezinye zisetshenziswe emgqeni wokuhlanganisa.

Izimiso zayo eziyisisekelo: Ukumaka nge-laser kusebenzisa i-laser beam ukumaka unomphela ingaphezulu lezinto ezahlukahlukene.Umthelela wokumaka uwukuveza izinto ezijulile ngokuhwamuka kwezinto ezingaphezulu, noma “uqopha” imikhondo ngokusebenzisa amakhemikhali nokomzimba wento engaphezulu ebangelwa amandla okukhanya, noma ukushisa ingxenye yento ngokusebenzisa amandla okukhanya. ukukhombisa ukumaka okudingekayo.Amaphethini we-Eclipse nombhalo.

Njengamanje, kunezimiso ezimbili ezaziwayo:

"I-Heat processing"ine-laser ye-laser beam ephezulu yamandla (iwukugeleza kwamandla agxilile), i-radiated ebusweni bento okufanele icutshungulwe, ingaphezulu lezinto ezibonakalayo limunca amandla e-laser, futhi likhiqize inqubo yokuvusa ukushisa endaweni ethile, ukuze ingaphezulu lezinto ((Noma coating) izinga lokushisa liyakhuphuka, libangele izenzakalo ezifana nokuguquguquka, ukuncibilika, ukuphuma, kanye nokuhwamuka.

"Ukusebenza okubandayo"(i-ultraviolet) ama-photons anamandla omthwalo ophezulu kakhulu anganqamula amabhondi amakhemikhali kuzinto ezibonakalayo (ikakhulukazi izinto eziphilayo) noma i-medium ezungezile ukuze idale umonakalo wenqubo ongashisi.Lolu hlobo lokucubungula okubandayo lubaluleke ngokukhethekile ekucubunguleni ukumaka kwe-laser, ngoba akusiyo ukukhipha okushisayo, kodwa ukucwecwa okubandayo okungakhiqizi imiphumela emibi "yokulimala okushisa" futhi kuphule isibopho samakhemikhali, ngakho-ke kuthinta ungqimba lwangaphakathi indawo ecutshunguliwe kanye nendawo ethile.Ayikhiqizi ukushisa noma ukubola kwe-thermal.

2.1Umgomo wokumaka nge-laser

I-RF Driver ilawula isimo sokushintsha se-Q-switch.Ngaphansi kwesenzo se-Q-switch, i-laser eqhubekayo iba igagasi lokukhanya elishayelayo elinenani eliphakeme elingu-110KW.Ngemva kokuba ukukhanya kwe-pulsed okudlula emgodini we-optical kufinyelela embundwini, ukukhishwa kwe-cavity ye-resonant kufinyelela ekwandiseni.Isibuko se-Beam, i-beam ikhuliswa yi-expander ye-beam bese idluliselwa esibukweni sokuskena.Izibuko zokuskena ze-X-axis kanye ne-Y-axis zishayelwa yi-servo motor ukuze zijikelezise (shwibela kwesokunxele nakwesokudla) ukuze kuskenwe ukubona.Ekugcineni, amandla e-laser aphinde athuthukiswe yinkambu yokugxila kwendiza.Gxila endizeni yokusebenza yokumaka, lapho yonke inqubo ilawulwa yikhompyutha ngokohlelo.

2.2Izici zokumaka nge-laser

Ngenxa yesimiso sawo esikhethekile sokusebenza, umshini wokumaka we-laser unezinzuzo eziningi uma kuqhathaniswa nezindlela zokumaka zendabuko (ukuphrinta kwephedi, ukufaka amakhodi, ukuguguleka kwe-electro-rosion, njll.).

1) Ukucubungula okungathintana naye

Ingaphrintwa kunoma iyiphi indawo evamile futhi engajwayelekile.Phakathi nenqubo yokumaka, umshini wokumaka we-laser ngeke uthinte into ephawuliwe futhi ngeke ukhiqize ukucindezeleka kwangaphakathi ngemva kokumaka;

2) Uhla olubanzi lokusetshenziswa kwezinto

ü Ingamakwa ezintweni zezinhlobo ezahlukene noma ubulukhuni, njengensimbi, ipulasitiki, izitsha zobumba, ingilazi, iphepha, isikhumba, njll.;

ü Ingahlanganiswa neminye imishini emgqeni wokukhiqiza ukuze kuthuthukiswe i-automation kanye nokusebenza kahle komugqa wokukhiqiza;

ü Uphawu lucacile, luqinile, luhle, futhi lusebenza ngempumelelo ngokumelene nokukhwabanisa;

ü Ayingcolisi imvelo futhi ayihambisani nemvelo;

ü Ijubane lokumaka liyashesha futhi ukumaka kwakhiwa ngesikhathi esisodwa, ngokuphila isikhathi eside, ukusetshenziswa kwamandla okuphansi kanye nezindleko eziphansi zokusebenza;

ü Nakuba utshalomali lwempahla yomshini wokumaka i-laser lukhudlwana kunolo lwempahla yokumaka evamile, ngokwezindleko zokusebenza, lungonga izindleko eziningi ezintweni ezisetshenziswayo, njengemishini ye-inkjet, edinga ukusebenzisa uyinki.

Isibonelo: ukumaka i-bearing surface-uma ukuthwala kubhalwe ngezingxenye ezintathu ezilinganayo, ingqikithi yezinhlamvu ezingu-18 No. 4, kusetshenziswa umshini wokumaka we-galvanometer, futhi impilo yesevisi yeshubhu lesibani se-krypton amahora angu-700, khona-ke i-bearing's ngayinye izindleko eziphelele zokumaka ngu-0.00915 RMB.Izindleko ze-electro-rosion lettering cishe zi-0.015 RMB/ucezu.Ngokusekelwe ekuphumeni konyaka kwamasethi ama-bearings ayizigidi ezi-4, ukumaka into eyodwa kuphela kunganciphisa izindleko okungenani ngo-65,000 RMB ngonyaka.

3) Ukusebenza kahle okuphezulu kokucubungula

I-laser beam ngaphansi kokulawulwa kwekhompyutha ingahamba ngesivinini esikhulu (kufika kumasekhondi angu-5-7), futhi inqubo yokumaka ingaqedwa ngemizuzwana embalwa.Ukuphrinta kwekhibhodi evamile yekhompyutha kungaqedwa ngemizuzwana engu-12.Uhlelo lokumaka nge-laser lufakwe isistimu yokulawula ikhompuyutha, engakwazi ukusebenzisana kalula nolayini wokuhlanganisa onesivinini esikhulu.

I-4) Ukunemba okuphezulu kokucubungula

I-laser ingakwazi ukusebenza phezu kwento ngogongolo oluncane kakhulu, futhi ububanzi bomugqa omncane bungafinyelela ku-0.05mm.

3.Izinhlobo zomshini wokumaka we-laser
