Kev cim laser yog ib qho txheej txheem uas tsis sib cuag uas siv lub teeb ci ntsa iab los tsim ib qho cim tas mus li ntawm qhov chaw ntawm cov khoom siv. Koj puas tau xav tsis thoob tias cov lej barcodes uas tsis muaj kev puas tsuaj ntawm cov khoom siv cav lossis cov cim me me ntawm cov khoom siv kho mob tau ua li cas? Tej zaum, koj tab tom saib qhov tshwm sim ntawm laser. Cov thev naus laus zis no yog lub hauv paus ntawm kev lag luam niaj hnub no rau ib qho laj thawj yooj yim:it yog tus cwj pwm los ntawm nws qib siab ntawm kev raug, kev ua tiav sai, thiab cov txiaj ntsig ntev.
Rau txhua lub lag luam uas koom nrog kev tsim khoom, kev taug qab thiab kev tsim hom tsis yog qhov tseem ceeb xwb; lawv tseem ceeb heev.Lub cim laseryog tus yuam sij rau kev ua tiav qhov no, muab ib txoj hauv kev txhim khu kev qha los ntxiv cov lej serial, QR codes, thiab cov logos uas kav ntev mus ib txhis.
Cia peb kawm ntxiv txog yam ua rau cov thev naus laus zis no tseem ceeb heev.
Cov Cim Laser Ua Haujlwm Li Cas? Kev Saib Xyuas Kom Zoo Dua Ntawm Cov Txheej Txheem
Txawm hais tias lub tswv yim ntawm "taw tes rau laser" zoo li yooj yim, lub khawv koob nyob hauv cov ntsiab lus. Cov ntaub ntawv sib txawv thiab cov txiaj ntsig xav tau xav tau ntau txoj kev sib txawv. Kev nkag siab txog cov txheej txheem no pab koj pom dab tsi yog laser marking siv rau hauv ntau yam kev siv.
Nov yog cov hau kev tseem ceeb uas lub laser tuaj yeem cim ib qho chaw:
Kev Txiav Laser:Qhov no yog txoj kev siv tau ntev tshaj plaws. Lub zog cua sov ntawm lub teeb laser ua rau cov khoom siv ua pa, tsim kom muaj qhov tob uas koj tuaj yeem hnov. Xav txog nws zoo li kev txiav digital rau hauv qhov chaw. Lub cim no tuaj yeem tiv taus qhov chaw ib puag ncig hnyav, kev puas tsuaj, thiab kev kho mob tom qab ua tiav.
Kev Txiav Laser:Xav tau kev ceev? Kev txiav yog koj cov lus teb. Nws yog ib qho txheej txheem ceev ceev uas lub laser yaj cov micro-surface. Cov khoom siv molten no nthuav dav thiab txias, tsim ib qho cim tsa, textured nrog kev sib piv siab. Nws zoo meej rau cov lej serial ntawm cov kab ntau lawm uas txav mus los sai.
Kev Siv Laser Annealing:Cov txheej txheem no yog hais txog kev ua kom zoo nkauj. Siv feem ntau rau cov hlau xws li hlau thiab titanium, lub laser maj mam ua kom cov khoom sov.hauv qab nonws qhov chaw yaj. Qhov no ua rau oxidation tsim nyob rau hauv qab ntawm qhov chaw, tsim kom muaj ib qho cim dub du, tas mus li uas tsis muaj cov khoom tshem tawm. Nws yog qhov tseem ceeb rau cov khoom siv kho mob qhov twg qhov chaw du thiab huv si tsis tuaj yeem sib tham tau.
Kev rho tawm:Xav txog koj muaj ib feem pleev xim thiab xav tsim ib qho kev tsim los ntawm kev qhia cov khoom siv hauv qab. Qhov ntawd yog ablation. Lub laser tshem tawm cov txheej sab saum toj (xws li xim lossis anodization) kom pom cov khoom siv sib txawv. Qhov no yog siv rau kev tsim cov nyees khawm backlit hauv tsheb thiab cov khoom siv hluav taws xob, feem ntau hu ua "hnub & hmo ntuj" tsim.
Kev Ua Npuas Ncauj & Carbonization:Cov txheej txheem tshwj xeeb no yog rau cov yas thiab cov khoom siv organic. Kev ua npuas dej maj mam yaj cov yas kom tsim cov pa roj, ua rau muaj cov cim xim dawb ntawm qhov chaw tsaus. Carbonization rhuav tshem cov tshuaj sib txuas hauv cov yas lossis ntoo xim dawb, ua rau cov khoom tsaus ntuj los tsim cov cim sib txawv siab.
Xaiv Cov Cuab Yeej Zoo: Sib phim Laser rau Cov Khoom Siv
Tsis yog txhua lub lasers yog tsim los sib npaug. Qhov kev xaiv zoo nyob ntawm cov khoom siv uas koj xav tau cim. Qhov no yog txiav txim siab los ntawm lub laser lub wavelength, ntsuas hauv nanometers (nm). Xav txog nws zoo li siv tus yuam sij raug rau lub xauv tshwj xeeb.
| Hom Laser | Qhov ntev ntawm lub zog | Zoo Tshaj Plaws Rau | Vim Li Cas Nws Ua Haujlwm |
| Laser fiber ntau | ~1064 nm | Cov Hlau (Hlau, Txhuas, Titanium, Tooj Liab), qee cov Yas | Tus "neeg ua haujlwm hnyav" ntawm kev lag luam. Nws cov wavelength ze-infrared yooj yim nqus los ntawm cov hlau, ua rau nws ua haujlwm tau zoo heev thiab siv tau ntau yam. |
| CO₂ Laser | ~10,600 nm | Cov Khoom Siv Organic (Ntoo, Iav, Ntawv, Tawv, Yas) | Tus tswv ntawm cov khoom tsis yog hlau. Nws cov wavelength infrared deb yog nqus tau zoo heev los ntawm cov organic compounds, ua rau pom tseeb yam tsis ua rau cov khoom puas tsuaj. |
| UV Laser | ~355 nm | Cov Yas Rhiab, Silicon, Iav, Khoom Siv Hluav Taws Xob | Hu ua "cold marking." Nws cov photons muaj zog heev rhuav tshem cov molecular bonds ncaj qha nrog qhov kub tsawg kawg nkaus. Qhov no zoo meej rau cov khoom yooj yim uas tsis tuaj yeem tswj tau qhov kub thiab txias. |
| Laser ntsuab | ~532 nm | Cov Hlau Muaj Nqis (Kub, Nyiaj), Tooj Liab, Cov Khoom Siv Uas Muaj Kev Cuam Tshuam Zoo | Ua kom tiav ib qho chaw tshwj xeeb. Nws nqus tau zoo dua los ntawm cov ntaub ntawv uas cuam tshuam cov wavelengths infrared txheem, uas ua rau muaj cov cim tseeb ntawm cov hlau mos lossis cov hlau cuam tshuam thiab qee yam yas. |
Kev Cim Laser Hauv Lub Ntiaj Teb Tiag: Cov Kev Siv Tseem Ceeb Hauv Kev Lag Luam
Yog li, koj tuaj yeem nrhiav tau laser marking qhov twg? Yuav luag txhua qhov chaw.
Tsheb thiab Aerospace:Cov khoom hauv cov lag luam no yuav tsum taug qab tau lawv lub neej tag nrho. Kev kos duab laser thiab kev annealing tsim cov cim uas tiv taus qhov kub thiab txias heev, kua dej, thiab kev puas tsuaj.
Cov Khoom Siv Kho Mob:Cov cai nruj ntawm FDA yuav tsum muaj Unique Device Identification (UDI) rau txhua yam khoom siv. Kev siv laser annealing ua rau cov cim du thiab huv ntawm cov cuab yeej phais thiab cov khoom cog tsis muaj kev cuam tshuam rau lawv qhov kev ua haujlwm.
Cov Khoom Siv Hluav Taws Xob & Cov Khoom Siv Semiconductor:Cov khoom me me xav tau cov cim me me dua. UV lasers ua tau zoo heev ntawm kev tsim cov cim me me ntawm cov silicon wafers thiab cov khoom siv hluav taws xob zoo nkauj yam tsis ua rau muaj kev puas tsuaj los ntawm cua sov.
Cov Khoom Siv Hniav Nyiaj Hniav Kub & Cov Khoom Muaj Nqis:Kev cim laser muab ib txoj hauv kev zoo nkauj thiab zais cia los ntxiv cov cim qhia, cov lej serial rau kev tiv thaiv kev cuav, thiab cov lus sau rau ntawm cov hlau muaj nqis.
Kev Siv Laser Marking Piv Rau Cov Txheej Txheem Ib Txwm Li Cas
Vim li cas ho hloov mus siv laser? Cia peb piv rau cov thev naus laus zis qub.
Kev Cim Laservs.Kev Luam Ntawv Inkjet:Cov kua mem tsuas yog ib ntus xwb thiab yuav tsum tau siv tas li. Nws tuaj yeem ploj mus, muaj xim av, thiab raug tshem tawm los ntawm cov tshuaj yaj. Cov cim laser yog cov cim tas mus li, tsis tas siv tas li, thiab ruaj khov dua.
Kev Cim Laservs.Dot Peen:Lub tshuab Dot peen siv lub zog ntaus lub carbide pin rau hauv cov khoom. Nws muaj suab nrov, qeeb dua, thiab muaj kev daws teeb meem tsawg. Kev cim laser yog ib qho txheej txheem ntsiag to, tsis sib cuag uas nrawm dua thiab tuaj yeem tsim cov logos thiab 2D codes uas muaj cov ntsiab lus ntxaws heev.
