Nyob rau hauv lub realm ntawm ultra-high precision manufacturing- qhov twg laser txiav txoj kev yuav tsum muaj tseeb thiab lithography theem yuav tsum tau nanometer-theem repeatability- cov lus tawm tswv yim yog ib qho tseem ceeb raws li lub tshuab tsav. Rau linear Module lwm tus neeg thiab cov khoom siv laser, qhov sib txawv ntawm qhov "zoo" txiav thiab "zoo meej" ib qho feem ntau los rau hauv encoder system.
Hauv plawv ntawm cov kev ua haujlwm siab - yog ib qho tseem ceeb ntawm cov khoom siv: lub iav iav nplai.
Thaum cov nplais hlau nplaum thiab hlau muaj lawv qhov chaw nyob rau hauv automation dav dav, qhov kev thov rau cov iav kho qhov muag hauv kev ntsuas tshuab yog tsav los ntawm qhov xav tau ntawm thermal stability thiab optical precision. Tsab ntawv xov xwm no tshawb txog vim li cas cov iav iav qhov ntsuas tseem yog tus qauv kub rau kev ntsuas qhov tseeb hauv cov ntawv thov kev lag luam siab heev.
Lub Physics ntawm Precision: Vim li cas iav?
Lub iav qhov ntsuas qhov tseeb ua raws li "tus kav" hauv cov kab hluav taws xob encoder. Nws yog ib lub iav tshwj xeeb (feem ntau yog iav-ceramic zoo li Zerodur lossis siab-kev ruaj khov fused silica) etched nrog microscopic kawm tiav.
Qhov zoo tshaj ntawm cov nplais iav tshaj cov hlau lossis hlau nplai yog nyob hauv peb lub cev tseem ceeb:
Tsawg Coefficient ntawm Thermal Expansion (CTE):
Nyob rau hauv siab - ib puag ncig precision, kub hloov pauv yog yeeb ncuab. Cov nplais hlau nthuav dav thiab cog lus nrog cov cua sov, qhia txog kev ntsuas qhov yuam kev. Precision iav nplai yog tsim los kom muaj qhov ze -zero CTE (feem ntau<0.05×10−6/K<0.05×10−6/K ). This ensures that the "ruler" does not change length even if the factory temperature varies, maintaining linear measurement accuracy without complex temperature compensation.
Optical Homogeneity:
High-zoo kho qhov muag iav muab qhov nruab nrab zoo ib yam rau lub teeb kis tau tus mob thiab kev xav. Qhov no tso cai rau lub readhead los xyuas cov theem hloov nyob rau hauv lub teeb tsis muaj clarity, enabling interpolation mus rau theem nanometer.
Mechanical stability:
Cov iav tiv thaiv kab mob sib nqus thiab tsis raug kev txom nyem los ntawm cov teebmeem hysteresis pom hauv daim kab xev sib nqus. Nws muab lub dav hlau nruj, ruaj khov siv uas tsis degrade raws sijhawm.
Nws Ua Haujlwm Li Cas: Optical Readhead
Kev sib cuam tshuam ntawm cov iav nplai thiab lub taub hau kho qhov muag yog ib qho txuj ci ntawm physics. Cov nplai muaj cov qauv "grating" meej- cov kab sib hloov pob tshab thiab opaque kab.
Raws li lub taub hau nyeem txav raws qhov ntsuas, nws tawm lub teeb ci (LED lossis Laser) los ntawm cov grating. Qhov no tsim tus qauv Moiré fringe. Photodetectors nyob rau hauv lub readhead tsom xam cov kev hloov siv ntawm cov fringes no.
Los ntawm kev siv cov iav iav nrog lub sijhawm zoo heev (piv txwv li, 4µm lossis 20µm), thiab kev sib txuas nrog cov khoom siv hluav taws xob, cov tshuab niaj hnub tuaj yeem ua tiav:
Kev daws teeb meem: nqes mus rau 1nm.
Qhov tseeb: ± 0.5μm / m ± 0.5μm / m lossis zoo dua.
Ceev: Muaj peev xwm ntsuas qhov nrawm tshaj 10 m / s.
Cov ntawv thov tseem ceeb
Rau peb cov neeg koom tes hauv kev lag luam laser thiab automation, kev xaiv ntawm iav nplai ncaj qha cuam tshuam rau lub peev xwm ntawm lub tshuab.
