Hauv kev tshuaj ntsuam xyuas qhov muag tsis zoo (AOI) thiab siab -throughput wafer defect mapping, sub-micron daws teeb meem tsis yog khoom kim heev- nws yog lub hauv paus tseem ceeb. Raws li optical sensors, kab -scan koob yees duab, thiab siab - magnification lo ntsiab muag ua tiav nanometer-scale pixel daws teeb meem, lub tshuab chassis txhawb cov tshuab no yuav tsum muaj xoom dynamic flexure thiab nyob ze -stantaneous vibration settling.
Thaum cov hlau nplaum thiab cov cam khwb cia hlau cam tau ntev tus qauv rau kev soj ntsuam kho qhov muag platforms, qhov kev txhoj puab heev nres - thiab - mus acceleration profiles ntawm niaj hnub gantry systems nthuav tawm lawv cov kev txwv. Txhawm rau kom ntes tau nkig, distortion- cov duab dawb ntawm sub-micron nplai, cov qauv tsim tau tig mus rau ultra- ntom ntom ntuj dub granite ua cov khoom siv zoo tagnrho.
I. Damping Dynamic Shock: Granite's Superior Attenuation Ratio
High- ceev AOI cov cav tov ua haujlwm ntawm kev ua haujlwm hnyav, nrog cov kab hluav taws xob ua haujlwm nrawm nrawm mus txog 2G kom luam theej duab siab - ntom ntom Circuit Court boards lossis semiconductor wafers. Cov kev hloov ceev ceev no ua rau cov neeg kho tshuab poob siab tsis ua haujlwm uas taug kev los ntawm lub tshuab thav duab, ua rau cov duab plooj thiab sensor repositioning qeeb.
Ntuj siab - ntom ntom dub granite (≈3,100 kg / m3) hais qhov no nrog rau qhov kev co intrinsic damping muaj peev xwm mus txog 15 npaug ntau dua li cov hlau cam khwb cia.
Micro-Crystalline Dissipation: Lub interwoven quartz thiab feldspar grain ciam ciam nyob rau hauv tuab dub granite hloov txhua yam vibrational zog mus rau qhov tsis muaj cua sov.
Lub Sijhawm Teeb Meem nrawm: Cov txheej txheem siab damping txo qhov seem ntawm kev vibration teeb tsa lub sij hawm los ntawm ntau pua milliseconds mus rau zero, tso cai rau AOI cov koob yees duab tua hluav taws tam sim ntawd tom qab nres yam tsis tau tos cov ncej resonance kom lwj.
II. Cov qauv loj thiab qis-Center- ntawm-Lub ntiajteb txawj nqus Base Topologies
Tsim ib lub granite chassis rau sub-micron optical tshuaj xyuas yuav tsum muaj kev faib tawm ntau dua li tsuas yog ntxiv qhov hnyav. Niaj hnub nimno AOI granite bases siv qis -center- ntawm-gravity topologies nrog kev sib xyaw hollow channel thiab optimized tav.
Integrated Cable thiab Air Ducts: Machined internal conduits tso cai pneumatics, fais fab kab, thiab fiber ntau -optic cables kom dhau los ntawm cov tub ntxhais ntawm granite hauv paus, tswj kom huv si nruab nrab ntawm lub ntiajteb txawj nqus thiab tshem tawm cov cab cuam tshuam.
Kinematic Mounting Bosses: Stainless hlau thiab threaded tooj dag inserts yog epoxy-anchored rau hauv precision-drilled granite pockets, muab siab -rub tawm- lub zog mounting nodes rau kho qhov muag kab, illumination rings, thiab linear motor stators yam tsis tau hloov cov pob zeb hauv zos.
III. Sub-Micron Flatness rau Linear Motor Guide Integration
Qhov tseeb ntawm AOI optical system nyob ntawm qhov ncaj thiab pitch / yaw / yob yuam kev ntawm nws cov lus tsa suab. Thaum mounting siab -precision linear motor theem ncaj qha mus rau granite nto, lub hauv paus mounting pads yuav tsum tau raws li nruj geometric kam rau ua.
Nanometer-Level Surface Flatness: Cov dav hlau siv tseem ceeb thiab cov mounting lem yog txhais tes-lapped rau Qib 000 tus qauv (<1.0 μm overall flatness across multi-meter spans), ensuring that linear motor carriages travel without vertical elevation changes.
Integrated Air Bearing Guide: High-qib dub granite saum npoo tuaj yeem polished rau daim iav heev-zoo li cov tiav tiav (Ra Tsawg dua lossis sib npaug li 0.1 μm), tso cai rau huab cua- cov theem coj mus rau hauv lub microscopic, tsis muaj kev sib txhuam ntawm cov cua compressed yam tsis muaj kev siv tshuab.
IV. Environmental Stress Relief thiab Ntev -Lub Sij Hawm Metrological Stability
Lub chassis tsim los rau sub-micron optical soj ntsuam yuav tsum tuav nws daim ntawv geometric ntau xyoo dhau los ntawm kev ua haujlwm tas mus li. Raw granite blocks siv nyob rau hauv precision AOI puag siv undergo natural ambient stress-relief aging ua ntej finishing.
Los ntawm kev tso cai rau sab hauv tectonic kev ntxhov siab los so kom ntev dua lub sijhawm laus, cov granite thaiv poob nws lub peev xwm rau microscopic warping. Ua ke nrog symmetric ribbing thiab peb - taw tes kinematic levelling, cov granite qauv muab ib tug immutable geometric datum uas tseem ruaj khov tiv thaiv ntev - cov ntaub ntawv creeping.
Anchoring the Next Generation of Machine Vision
Raws li siab - ceev AOI systems thawb cov ciam teb ntawm optical magnification thiab spatial daws teeb meem, lub tshuab chassis yuav tsum evolve los ntawm ib tug passive kev them nyiaj yug ncej rau hauv ib tug active precision tivthaiv. Los ntawm kev sib txuas cov khoom siv siab ceev, kev co nrawm nrawm, thiab nanometer- theem nto tiav, engineered granite structural Cheebtsam muab lub unwavering lub cev ruaj khov uas yuav tsum tau rau lub hwj chim lub ntiaj teb no xav tau tshaj lub tshuab tsis pom kev platforms.
