Laser Marking: Ib qho kev lag luam thev naus laus zis rau Tsis yog -Kev Sib cuag, Kev Ua Lag Luam tas mus li. Laser marking is a technique that utilizes a high-energy-density laser beam to locally irradiate the surface of a material, causing the surface layer to vaporize, undergo color changes, or trigger physicochemical reactions, thereby leaving a permanent mark. Raws li ib qho ntawm feem ntau siv teb nyob rau hauv laser ua technology, laser marking boasts cov yam ntxwv txawv -xws li tsis yog -kev sib cuag, muaj kuab paug- ua dawb, siab precision, siab ceev, thiab mus tas li kos npe rau - ua rau nws ib tug indispensable txhais tau tias ntawm kev txheeb xyuas cov txheej txheem nyob rau hauv niaj hnub industrial manufacturing. Los ntawm kev tswj hwm lub computer, cov thev naus laus zis no scans lub teeb laser hla cov khoom siv saum npoo av, ua kom cov ntawv sau meej meej, cov cim, QR cov lej, cov qauv, thiab txawm tias cov duab. Piv nrog rau cov txheej txheem ib txwm muaj xws li number case printing, mechanical engraving, los yog chemical etching, laser marking yuav tsum tsis muaj kev sib cuag nrog lub workpiece; Yog li ntawd, nws induces tsis muaj mechanical kev nyuaj siab los yog deformation. Tsis tas li ntawd, cov qhab nia ua tau yog ruaj khov, tiv taus kev puas tsuaj, thiab corrosion- pov thawj, ua cov cuab yeej tshwj xeeb zoo - haum rau siab - kev ua tiav ntawm ntau yam ntaub ntawv, suav nrog hlau, yas, ceramics, iav, thiab ntoo. Tsav los ntawm kev nce qib hauv laser thev naus laus zis, laser marking tau pom muaj ntau daim ntawv thov thoob plaws ntau lub lag luam-xws li hluav taws xob, tsheb, khoom siv kho mob, ntim khoom noj, thiab cov hniav nyiaj hniav kub- tshwm sim los ua ib qho tseem ceeb rau cov khoom lag luam traceability, tiv thaiv{18}} cuav pov thawj, thiab tus kheej.

Keeb kwm luv luv: Cov evolution ntawm laser npav tshuab yog inextricably txuas rau kev nce qib hauv laser technology nws tus kheej; nws txoj kev loj hlob tau loj hlob los ntawm peb theem sib txawv: kev tshawb nrhiav thaum ntxov, kev paub txog thev naus laus zis, thiab kev nthuav dav ntau yam. Kev Tshawb Fawb Txog Thaum Ntxov (Late 1970s - 1980s): Laser marking technology originated nyob rau hauv lig 1970s thiab thaum ntxov 1980s. Nyob rau lub sijhawm no, cov cuab yeej kos npe cia siab rau feem ntau ntawm CO2 lasers thiab teeb lub teeb -pumped solid-xeev lasers (xws li Nd:YAG). Raws li laser technology tseem nyob rau hauv nws nascent theem thaum lub sij hawm, cov khoom yog loj thiab txwv tsis pub kim; Tsis tas li ntawd, cov kev tswj hwm feem ntau siv loj- hom plotter-raws li cov txheej txheem- uas yog tus cwj pwm los ntawm kev qeeb qeeb thiab tsis muaj qhov tseeb- ua rau muaj qhov txwv tsis pub siv, tsom feem ntau ntawm cov haujlwm yooj yim kos npe ntawm cov hlau. Technological Maturity and Widespread Adoption (1990s – Early 2000s)
Nkag mus rau xyoo 1990, tau tsav los ntawm kev nce qib hauv semiconductor thev naus laus zis, diode-pumped solid- xeev lasers maj mam loj hlob thiab pom daim ntawv thov hauv thaj chaw ntawm laser npav, txo cov nqi khoom siv thaum txhim kho kev ntseeg tau. Raws li qhov tshwm sim, cov kev tswj hwm rau cov cuab yeej laser npav tau dhau los ua qhov kev hloov pauv tseem ceeb: nce los ntawm lub sijhawm thaum ntxov ntawm loj - hom plotters mus rau lub sijhawm ntawm cov iav rotating, thiab thaum kawg tsim lub galvanometer scanning system raws li tus qauv tseem ceeb. Pib xyoo 1998, siab -ceev galvanometer tshuab uas tau tsav los ntawm servo motors tau pib siv rau ntawm qhov loj hauv Suav teb; qhov kev txhim kho no tau txhim kho cov cim nrawm thiab qhov tseeb ntawm qhov chaw, kos lub ntsiab lus ntawm laser npav tshuab nkag mus rau theem ntawm kev loj hlob thiab kev siv dav dav. Diversified Development (21st Century – Tam sim no)
Nyob rau hauv xyoo tas los no, propelled los ntawm kev nce qib sai ntawm fiber ntau lasers thiab ultraviolet (UV) lasers, laser marking technology tau nkag mus rau theem tshiab ntawm ntau haiv neeg txoj kev loj hlob. Fiber lasers- txawv los ntawm lawv cov high electro-kev hloov kho qhov muag pom kev, kev ua haujlwm ntev, thiab kev txij nkawm-kev ua haujlwm dawb- tau tshwm sim sai sai raws li qhov kev xaiv zoo tshaj plaws rau daim ntawv sau npe hlau. Lub caij no, UV lasers-vim lawv qhov tshwj xeeb "txias ua" cov yam ntxwv- tau ruaj khov txoj haujlwm tseem ceeb hauv kev ua tiav cov haujlwm ua haujlwm tsis zoo rau thermal puas, xws li cov khoom siv hluav taws xob thiab kev lag luam tshuaj. Tsis tas li ntawd, qhov tshwm sim ntawm cov thev naus laus zis tshiab- suav nrog 3D dynamic marking, ntawm -the -fly marking, thiab lub zeem muag- taw qhia qhov chaw- tau nthuav dav ntxiv rau thaj tsam ntawm daim ntawv teev npe laser, ua rau nws los daws qhov kev xav tau ntawm 5 qhov kev xav tau, thiab kev nyuaj siab nyob rau hauv - kab ua ib puag ncig.
