Anthu nthawi zambiri amawona kuyika chizindikiro ndi laser ndi chinthu chomwecho. Ndipotu, iwo ndi osiyana pang'ono.
Ngakhale onse laser chodetsa ndi laser chosema ntchito laser kusiya zizindikiro inerasable pa zipangizo. Koma kujambula kwa laser kumapangitsa kuti zinthuzo zisungunuke pomwe chizindikiro cha laser chimapangitsa kuti zinthuzo zisungunuke. Malo osungunuka adzakula ndikupanga gawo la ngalande la 80µm kuya, lomwe lidzasintha kuuma kwa zinthuzo ndikupanga kusiyana kwakuda ndi koyera. Pansipa tikambirana zinthu zomwe zimakhudza kusiyana kwakuda ndi koyera pakuyika chizindikiro cha laser.
3 Njira zolembera laser(1) Gawo 1: Mtengo wa laser umagwira ntchito pamtunda
Chomwe chimayika chizindikiro cha laser ndi chojambula cha laser onsewo ndikuti mtengo wa laser ndi pulse. Ndiye kuti, makina a laser amalowetsa kugunda pakapita nthawi inayake. Laser ya 100W imatha kulowetsa 100000 kugunda sekondi iliyonse. Chifukwa chake, titha kuwerengera kuti mphamvu ya pulse imodzi ndi 1mJ ndipo nsonga yapamwamba imatha kufika 10KW.
Kuwongolera mphamvu ya laser yomwe imagwira ntchito pazinthuzo, ndikofunikira kusintha magawo a laser. Ndipo magawo ofunikira kwambiri ndikuthamanga kwa sikani ndi mtunda wa sikani, chifukwa awiriwa amasankha kagawo kakang'ono ka ma pulse oyandikana omwe amagwira ntchito pazinthuzo. Kuyandikira pafupi ndi nthawi ya pulse, mphamvu zambiri zimatengedwa.
Poyerekeza ndi kujambula kwa laser, chizindikiro cha laser chimafuna mphamvu zochepa, kotero liwiro lake lojambula limakhala lofulumira. Posankha kusankha laser chosema kapena laser chodetsa, kupanga sikani liwiro ndi gawo lalikulu.
(2) Gawo 2: Zinthuzi zimatenga mphamvu ya laser
Pamene laser imagwira ntchito pamtunda, mphamvu zambiri za laser zidzawonetsedwa ndi zinthu zakuthupi. Gawo laling'ono chabe la mphamvu ya laser limatengedwa ndi zinthuzo ndikusandulika kutentha. Kuti zinthuzo zisungunuke, kujambula kwa laser kumafuna mphamvu zambiri, koma chizindikiro cha laser chimangofunika mphamvu zochepa kuti zisungunuke zidazo.
Mphamvu yotengedwa ikasanduka kutentha, kutentha kwa zinthu kumawonjezeka. Zikafika posungunuka, zinthu zakuthupi zimasungunuka kuti zisinthe.
Kwa laser wa 1064mm wavelength, ili ndi pafupifupi 5% mayamwidwe a aluminiyamu ndi 30% yachitsulo. Izi zimapangitsa anthu kuganiza kuti chitsulo ndi chosavuta kuyika chizindikiro cha laser. Koma sizili choncho. Tiyeneranso kuganizira za zinthu zina zakuthupi, monga malo osungunuka.
(3) Khwerero 3: Pamwamba pa zinthuzo padzakhala ndi kufalikira kwapaderalo ndi kusintha kwamphamvu.
Zinthu zikasungunuka ndikuzizira mu ma milliseconds angapo, kuuma kwa zinthuzo kumasintha ndikupanga chilemba chokhazikika chomwe chimaphatikizapo nambala ya seriyo, mawonekedwe, logo, ndi zina.
Kulemba mitundu yosiyanasiyana pazakuthupi kumapangitsanso kusintha kwamtundu. Pakuyika chizindikiro cha laser chapamwamba, kusiyanitsa kwakuda ndi koyera ndiye muyezo wabwino kwambiri woyesera.
Pamwamba pa zinthu zovunda zikawoneka ngati kuwala kwachitika, zinthuzo zimaoneka zoyera;
Pamwamba pa zinthu zokakala zikatenga kuwala kwambiri, zinthuzo zimaoneka ngati zakuda.
Pomwe pakujambula kwa laser, kugunda kwamphamvu kwamphamvu kwa laser kumagwira ntchito pamtunda. Mphamvu ya laser imasandulika kutentha, kutembenuza zinthuzo kukhala zolimba kupita ku gasi kuti zichotse zinthuzo.
Ndiye kusankha laser chodetsa kapena laser chosema?Pambuyo podziwa kusiyana pakati pa chizindikiro cha laser ndi laser engraving, chinthu chotsatira chomwe muyenera kuganizira ndikusankha chomwe mungasankhe. Ndipo tiyenera kuganizira zinthu zitatu.
1.Abrasion resistance
Laser chosema chili ndi kulowa mwakuya kuposa chizindikiro cha laser. Choncho, ngati chidutswacho chiyenera kugwiritsidwa ntchito m'malo omwe amakhudza abrasion kapena amafuna post processing ngati kuphulika kwapamwamba kapena kutentha kwa kutentha, ndi bwino kugwiritsa ntchito laser chosema.
2.Processing liwiro
Poyerekeza ndi chosema laser, laser chodetsa ali ndi zochepa zozama malowedwe, kotero liwiro processing ndi apamwamba. Ngati malo ogwirira ntchito omwe ntchitoyo ikugwiritsidwa ntchito sikuphatikizana ndi abrasion, tikulimbikitsidwa kugwiritsa ntchito chizindikiro cha laser.
3.Kugwirizana
Kuyika chizindikiro kwa laser kumasungunula zinthuzo kuti zipange magawo ang'onoang'ono osagwirizana pomwe kujambula kwa laser kumapangitsa kuti zinthuzo zisungunuke ndikupanga poyambira. Popeza laser chosema amafuna mphamvu zokwanira laser kuti zinthu kufika kutentha sublimation ndiyeno nthunzi mu milliseconds angapo, laser chosema sangathe anazindikira zipangizo zonse.
Kuchokera pakufotokozera pamwambapa, tikukhulupirira kuti tsopano mukumvetsetsa bwino za laser engraving ndi laser.
Pambuyo posankha kuti musankhe, chotsatira ndikuwonjezera chiller chogwira mtima. S&A mafakitale ozizira amapangidwa makamaka kwa mitundu yosiyanasiyana ya makina laser chodetsa, laser chosema makina, laser kudula makina, etc. dongosolo la laser kuchokera ku mphamvu yaying'ono kupita ku mphamvu yapakatikati.
