AOI tshuaj xyuas ntawm cov ntawv luam tawm Circuit Board
Tso lus
Automatic Optical Inspection (AOI) thev naus laus zis feem ntau yog siv lub koob yees duab los luam theej duab saum npoo ntawm lub rooj tsav xwm luam tawm rau kev ua cov duab thiab kev tsom xam, xyuas kom raug thiab txheeb xyuas cov kev sib txuas hluav taws xob, cov haujlwm ua haujlwm, thiab cov ntawv nyeem ntawm lub rooj tsav xwm Circuit Court. Tsis zoo li kev soj ntsuam pom ib txwm muaj, AOI kev tshuaj xyuas tsis tuaj yeem tsuas yog kuaj pom cov teeb meem tsis yooj yim uas nyuaj rau kev soj ntsuam nrog lub qhov muag liab qab, tab sis kuj tseem txhim kho kev tsim khoom ntawm cov laug cam thiab txo cov kev ua yuam kev uas yuav tshwm sim los ntawm kev pom kev qaug zog hauv kev tsim cov txheej txheem.
Tshwj xeeb, AOI thev naus laus zis feem ntau suav nrog peb kauj ruam hauv qab no:
Thawj kauj ruam yog preprocessing, uas ua cov txheej txheem luam theej duab Circuit Court board duab thiab hloov nws mus rau hauv cov duab digital, uas yog, los ntawm cov duab grayscale mus rau binary duab. Lub hom phiaj tseem ceeb ntawm cov txheej txheem no yog hloov mus rau ntau hom Circuit Court boards thiab txheej txheem dawb fonts.
Qhov thib ob kauj ruam yog feature extraction. Siv cov duab ua cov algorithms los rho tawm ntau yam ntawm cov duab digital, nrog rau kev sib txuas hluav taws xob (cov pob qij txha), cov cuab yeej ua haujlwm, cov duab ntawv, thiab lwm yam. Rau kev tshuaj xyuas cov ntaub qhwv thiab pins, kev kawm sib sib zog nqus los yog cov cuab yeej txawj ntse siv tau los ua kom tiav ntau dua. thiab nrhiav kom raug.
Qhov thib peb kauj ruam yog kev sib piv kev txheeb xyuas, uas siv cov ntaub ntawv sau los txheeb xyuas cov qauv ntawm ntau lub rooj tsav xwm hauv Circuit Court. Qhov no tuaj yeem txiav txim siab sai thiab raug txiav txim siab seb qhov zoo ntawm lub rooj tsav xwm hauv Circuit Court ua tau raws li cov qauv, kev txhim kho kev ua tau zoo thiab tag nrho cov khoom ntawm pawg thawj coj saib zoo.
AOI thev naus laus zis tau dhau los ua cov thev naus laus zis tseem ceeb hauv kev tsim khoom thiab tsim cov ntawv luam tawm Circuit Board. Nws tuaj yeem tsis tsuas yog txhim kho qhov zoo thiab kev ua haujlwm ntawm cov ntawv luam tawm Circuit Board ntau lawm, tab sis kuj txo qhov kev cia siab ntawm qhov muag liab qab hauv phau ntawv txheej txheem thiab txhim kho cov khoom nrawm. Nyob rau hauv lub neej yav tom ntej, tsis siv neeg kho qhov muag nrhiav tshuab nrog ntau dua teeb liab-rau-suab nrov piv thiab ntau qhov tseeb algorithms yuav coj peb ntau lub cib fim thiab kev ua tau zoo rau kev tsim khoom ntse.
