Kusanthula kwa magwiridwe antchito a zida zosiyanasiyana zowunikira mawonekedwe a SMT AOI

a) : Ntchito kuyeza solder phala kusindikiza khalidwe anayendera makina SPI pambuyo makina osindikizira: SPI anayendera ikuchitika pambuyo solder phala yosindikiza, ndi zolakwika mu ndondomeko yosindikiza angapezeke, potero kuchepetsa soldering zilema chifukwa cha osauka solder phala. kusindikiza pang'ono.Zowonongeka zosindikizira zikuphatikizapo mfundo zotsatirazi: osakwanira kapena owonjezera kwambiri pa mapepala;makina osindikizira;milatho ya malata pakati pa mapepala;makulidwe ndi kuchuluka kwa phala losindikizidwa la solder.Pakadali pano, payenera kukhala data yamphamvu yowunikira njira (SPC), monga zosindikiza zosindikizira ndi zidziwitso za voliyumu ya solder, komanso zidziwitso zamakhalidwe abwino za solder zosindikizidwa zidzapangidwanso kuti ziwunikidwe ndikugwiritsidwa ntchito ndi ogwira ntchito yopanga.Mwa njira iyi, ndondomekoyi imapangidwa bwino, ndondomekoyi imapangidwa bwino, ndipo mtengo wake umachepetsedwa.Zida zamtunduwu pakadali pano zagawidwa m'mitundu ya 2D ndi 3D.2D sangathe kuyeza makulidwe a solder phala, kokha mawonekedwe a solder phala.3D imatha kuyeza makulidwe a phala la solder ndi dera la solder phala, kuti voliyumu ya solder phala iwerengedwe.Ndi miniaturization wa zigawo zikuluzikulu, makulidwe a solder phala chofunika zigawo zikuluzikulu monga 01005 ndi 75um okha, pamene makulidwe ena wamba zigawo zikuluzikulu ndi za 130um.Chosindikizira chodziwikiratu chomwe chimatha kusindikiza makulidwe osiyanasiyana a phala la solder chatulukira.Choncho, 3D SPI yekha angakwaniritse zosowa za m'tsogolo solder phala ndondomeko ulamuliro.Ndiye ndi mtundu wanji wa SPI womwe tingakwaniritsedi zosowa za ndondomekoyi mtsogolomu?Zofunikira izi:

1. Iyenera kukhala 3D.
2. Kuyang'ana kothamanga kwambiri, kuyeza kwa makulidwe a laser SPI ndikolondola, koma kuthamanga sikungakwaniritse zofunikira zopanga.
3. Kukula koyenera kapena kosinthika (kukula kwa kuwala ndi digito ndizofunikira kwambiri, magawowa amatha kudziwa kuthekera komaliza kwa chipangizocho. kuzindikiritsa ma aligorivimu operekedwa ku pulogalamu ya AOI ili ndi chidziwitso chokwanira komanso chidziwitso chazithunzi).Komabe, pixel ya kamera ikakhazikitsidwa, kukulitsa kwake kumakhala kofanana ndi FOV, ndipo kukula kwa FOV kudzakhudza liwiro la makinawo.Pa bolodi lomwelo, zigawo zazikulu ndi zazing'ono zimakhalapo nthawi imodzi, choncho ndikofunika kusankha chisankho choyenera cha optical kapena chosinthika cha optical resolution malinga ndi kukula kwa zigawo zomwe zimagwiritsidwa ntchito.
4. Gwero loyatsa losasankha: kugwiritsa ntchito magetsi osinthika kudzakhala njira yofunikira yowonetsetsa kuti kuchuluka kwazovuta kuzizindikira.
5. Kulondola kwapamwamba komanso kubwerezabwereza: Miniaturization ya zigawo zimapanga kulondola ndi kubwereza kwa zipangizo zomwe zimagwiritsidwa ntchito popanga zinthu zofunika kwambiri.
6. Kusaweruzika kotsika kwambiri: Pokhapokha pakuwongolera kuchuluka kwachiweruzo molakwika komwe kungapangitse kupezeka, kusankha komanso kugwira ntchito kwa chidziwitso chomwe chimabweretsedwa ndi makinawo kuti chigwiritsidwe ntchito.
7. Kusanthula ndondomeko ya SPC ndikugawana zambiri ndi AOI m'malo ena: kusanthula kwamphamvu kwa SPC, cholinga chachikulu cha kuyang'anira mawonekedwe ndikuwongolera njira, kulinganiza ndondomekoyi, kukwaniritsa momwe zinthu zilili bwino, ndikuwongolera ndalama zopangira.

b) .AOI kutsogolo kwa ng'anjo: Chifukwa cha miniaturization ya zigawo zikuluzikulu, n'zovuta kukonza 0201 chigawo cholakwika pambuyo soldering, ndi zolakwika 01005 zigawo zikuluzikulu sangathe kukonzedwa kwenikweni.Choncho, AOI kutsogolo kwa ng'anjo idzakhala yofunika kwambiri.AOI yomwe ili kutsogolo kwa ng'anjoyo imatha kuzindikira zolakwika za njira yoyikamo monga kusanja molakwika, magawo olakwika, zigawo zomwe zikusowa, magawo angapo, ndi polarity reverse.Choncho, AOI kutsogolo kwa ng'anjoyo iyenera kukhala pa intaneti, ndipo zizindikiro zofunika kwambiri ndizothamanga kwambiri, kulondola kwakukulu ndi kubwerezabwereza, ndi kulingalira molakwika kochepa.Panthawi imodzimodziyo, imathanso kugawana chidziwitso cha deta ndi njira yodyetserako chakudya, imangozindikira mbali zolakwika za zigawo zowonjezera mafuta pa nthawi yowonjezera mafuta, kuchepetsa zolakwika za dongosolo, komanso kutumiza chidziwitso chopotoka cha zigawozo ku dongosolo la SMT kuti lisinthe. pulogalamu yamakina a SMT nthawi yomweyo.

c) AOI pambuyo pa ng'anjo: AOI ikatha ng'anjo imagawidwa m'njira ziwiri: pa intaneti komanso popanda intaneti molingana ndi njira yokwerera.AOI pambuyo pa ng'anjo ndi mlonda womaliza wa mankhwala, kotero pano ndi AOI yogwiritsidwa ntchito kwambiri.Iyenera kuzindikira zolakwika za PCB, zolakwika zamagulu ndi zolakwika zonse mumzere wonse wopanga.Ndi mitundu itatu yokha yowala yowala kwambiri ya dome ya LED yomwe imatha kuwonetsa mawonekedwe osiyanasiyana a solder kuti azindikire zolakwika zowotchera.Choncho, mtsogolomu, AOI yokha ya gwero la kuwala ili ndi malo opangira chitukuko.Zachidziwikire, m'tsogolomu, kuti muthane ndi ma PCB osiyanasiyana Dongosolo la mitundu ndi mitundu itatu ya RGB imakhalanso yokonzekera.Ndi kusinthasintha.Ndiye ndi mtundu wanji wa AOI pambuyo pa ng'anjo yomwe ingakwaniritse zosowa za chitukuko chathu cha SMT mtsogolo?Ndiko kuti:

1. liwilo lalikulu.
2. Mkulu mwatsatanetsatane ndi mkulu repeatability.
3. Makamera apamwamba kwambiri kapena makamera osinthasintha: amakwaniritsa zofunikira za liwiro ndi kulondola nthawi imodzi.
4. Kusaganizira molakwika komanso kuphonya chiweruzo: Izi zikuyenera kuwongoleredwa pa pulogalamuyo, ndipo kuzindikira kwa mawonekedwe a kuwotcherera kumatha kuyambitsa kuweruza molakwika komanso kuphonya chiweruzo.
5. AXI pambuyo pa ng'anjo: Zowonongeka zomwe zingathe kuyang'aniridwa zikuphatikizapo: zolumikizira zogulitsira, milatho, miyala yam'manda, solder yosakwanira, pores, kusowa kwa zigawo, IC kukweza mapazi, IC pang'ono malata, ndi zina zotero. monga BGA, PLCC, CSP, ndi zina zotero. Ndi chowonjezera chabwino ku kuwala kowoneka AOI.
