Udindo wa AOI mu SMT Processing

Makina a SMT AOIndiye chidule cha Automatic Optical Inspection Instrument, gawo lalikulu limagwiritsidwa ntchito kuzindikira mtundu wareflow uvuni, monga piritsi loyimilira loyipa, ngakhale mlatho, mikanda ya malata, malata ambiri, mbali zina zomwe zikusowa, ndi zina zotero zimatha kuzindikirika, zomwe nthawi zambiri zimakhala kumbuyo kwa mzere wonse wa SMT, kupititsa patsogolo bwino komanso kulondola kwa kuzindikira ndi kusintha. mlingo wowongoka.

Mfundo yogwiritsira ntchito makina a AOI

AOI ndi chojambulira cha kuwala, kuchokera ku liwu la Chitchaina titha kudziwa komanso zokhudzana ndi kuwala, mawonekedwe owoneka bwino ndi kamera (lens), ndipo chimodzi mwazinthu zazikulu za AOI ndi mandala.Pamene makina oyika aikidwa pambuyo pa PCBA, malo ogwirira ntchito otsatirawa ndi AOI kuyendera, PCBA mu mawonekedwe a AOI workbench, lens idzayang'ana PCBA motsatizana, ndiyeno kupyolera mu AOI algorithm yowonetsera kupanga chithunzi chowoneka cha maso, ngati zoipa, izo lipoti zolakwa, ndipo mwamsanga chifukwa cha zoipa, ngati OK adzakhala mwachindunji PASS, yendani ku ntchito yotsatira.

Momwe mungadziwire ngati zili bwino kapena zoyipa, chifukwa chake ndikuti deta ya OK board idzasungidwa mu database ya algorithm, pakakhala kusiyana ndi database mu algorithm, ndiye kuti cholakwikacho chidzanenedwa (nthawi zina). , pambuyo poyang'anitsitsa zowoneka bwino, ndiye kuti detayi iyenera kusungidwa m'dawunilodi mu nthawi kuti zisapitirire kubwereza zolakwika).Ngati cholakwika chikanenedwa kenako chikapezeka kuti chilibe vuto poyang'anira zowonera pamanja, uinjiniya ndi ukadaulo ziyenera kudziwitsidwa munthawi yowunikira zolakwika, kukonza njira ndi kukonzanso zina.

Chifukwa chiyani pali AOI yoyambira ng'anjo?

General AOI ali mu ng'anjo, ng'anjo ya AOI imayikidwa kutsogolo kwa bonder yogwira ntchito zambiri, chifukwa PCBA ina imafunika kuyika chivundikiro chotchinga, ndipo chivundikiro chotchinga chili pansi pa kuyika kwa zida zamagetsi, ndipo AOI siyitha kuwona chivundikiro chotchinga kuti muwone kuyika kwabwino (zigawo zolakwika, zosowa, ndi zina zotero), ndiye muyenera kuwonjezera AOI kutsogolo kwa makina ogwiritsira ntchito zambiri kuti muwone kuyika kwa bonder (chivundikiro chotchinga chambiri chimayikidwa pamipikisano- mgwirizano wogwira ntchito).

Chifukwa chiyani kuyang'ana pamanja kuli kofunikira pomwe pali AOI?

AOI ikhoza kupititsa patsogolo luso la kuzindikira, ngakhale AOI imasunga kuchuluka kwa deta yowotcherera yoyipa, koma ndondomeko yoyika zinthu zosiyanasiyana, padzakhala zifukwa zambiri zomwe zimayambitsa zoipa, kotero nthawi zina khalidwe la kuwotcherera limakhala labwino, komanso kuoneka zolakwika, ndiye muyenera pamanja zithunzi anayendera, kotero pali AOI, komanso sangasiye makonzedwe a Buku zithunzi anayendera positi.

Chifukwa chiyani mukufunikira 3D AOI mukakhala ndi 2D AOI?

Nthawi zambiri mafakitale ambiri amakhala ndi 2D AOI, koma ndikukula mwachangu kwa zinthu zamagetsi, ma IC ophatikizika ochulukira amagwiritsidwa ntchito kwambiri, ndipo 2D AOI siyimatha kuzindikira kutalika koyandama, kupindika ndi zolakwika zina, kotero makasitomala amalola mafakitale opangira zinthu kuwonjezera 3D AOI khalidwe ndi mbiri ya mankhwala.
