1. Ua Cov Ntawv Txiav Txim Siv Cov Qauv Ntsuas: Sau cov qauv ntsuas tus qauv nrog rau cov hlaws hla, cov voj voog sib xyaw, cov kab zoo (0.1 ~ 0.2 hli), thiab cov ntawv me me -.
Sau 200 nplooj ntawv txhua qhov sib txawv ntawm qhov sib txawv (tsawg ceev → nruab nrab ceev → kev kub ceev), thiab xaiv cov qauv los ntawm thawj zaug, nruab nrab, thiab zaum kawg rau kev sim.
2. Kev ntsuas ntsuas ntsuas (Qhov tseeb tshaj plaws): Siv lub iav magnifying (20 ~ 40x), vernier calipers, los yog lub zeem muag ntsuas ntsuas ntsuas qhov tsis zoo ntawm cov cim npe.
Kev ntsuas qhov chaw suav nrog plaub lub kaum ntse ntse thiab qhov chaw nruab nrab ntawm cov khoom luam tawm, siv 3 qhov kev ntsuas ntawm txhua qhov chaw, thiab siv tus nqi siab tshaj plaws raws li tus nqi sau npe yuam kev.
Kev lag luam Standards:
Siab -Speed/Fine Machines: Tsawg dua los yog sib npaug li 0.1 hli
Ordinary Semi-Cov Tshuab Tsis Siv Neeg: Tsawg dua lossis sib npaug li 0.15 ~ 0.2 hli
Batch Consistency: Tsawg dua lossis sib npaug li 0.05 hli
3. Visual Comparison Method (Quick Initial Judgement)
Raws li cov qauv teeb pom kev zoo, saib seb cov cim npe puas raug siv lub siab - magnification magnifying iav.
If obvious ghosting, blurred edges, or color fringing are visible to the naked eye, the registration has exceeded the standard (usually deviation >0.1 hli).
4. Digital Image Analysis Method (tseem siv tau rau cov khoom lag luam tsis tiav)
Tau txais cov duab digital ntawm cov ntaub ntawv luam tawm siv lub siab - kev daws teeb meem scanner lossis lub koob yees duab.
Siv cov duab ua software (xws li OpenCV) txhawm rau txheeb xyuas qhov sib koom ua ke ntawm cov ntsiab lus tshwj xeeb thiab cia li suav qhov sib cuam tshuam - phaj hloov, nrog qhov tseeb ntawm ± 0.02 hli.
5. Kev ntsuas kev ruaj ntseg tsis tu ncua
Sau 500 ~ 1000 nplooj ntawv txuas ntxiv mus kuaj qhov ruaj khov ntawm kev sau npe raug.
Tom qab nres thiab rov pib dua, ua tib zoo saib xyuas qhov tseeb ntawm qhov rov pib dua (nws yuav tsum rov qab tsis pub dhau 3 nplooj ntawv) txhawm rau ntsuas cov cuab yeej muaj peev xwm ua kom muaj zog.
6. Kev daws teeb meem cuam tshuam txog Kev sau npe tsis raug tuaj yeem tshwm sim los ntawm cov laj thawj hauv qab no, uas yuav tsum tau kuaj xyuas ib qho los ntawm ib qho:
Mechanical teeb meem: tsis ruaj tsis khov lub tog raj kheej kev koom tes, xoob qhia rails, ntawv pub gripper hloov chaw;
Khoom Deformation: ntawv lossis ntaub nqus dej thiab o, luam ntawv phaj stretching;
Cov Txheej Txheem Txheej Txheem: Kev siv dej ntau dhau los ua rau muaj kev hloov pauv, ntau tus lej viscosity siab ua rau slippage;
Environmental Factors: Kev hloov pauv ntawm qhov kub thiab av noo cuam tshuam rau cov khoom seem stability.
