SAKI smt 2d aoi makina BF-TristarⅡ

SAKI BF-TristarⅡ ndi m'badwo watsopano wa 2D automatic Optical inspection system (AOI) yomwe idakhazikitsidwa ndi SAKI, yokonzedwa kuti iwunikenso mwatsatanetsatane pamisonkhano ya PCB. Zipangizozi zimagwiritsa ntchito makina opangira makamera atatu ndikuphatikiza ukadaulo wowunikira ma multispectral kuti akwaniritse kuyang'ana kozungulira kwa zigawo za SMT, kuwongolera kwambiri kulondola ndi kuwongolera bwino.

2. Mfundo yogwira ntchito

2.1 Optical imaging system

Magulu atatu a makamera a CCD okwera kwambiri amagwiritsidwa ntchito nthawi imodzi kujambula zithunzi kuchokera kumbali zosiyanasiyana (nthawi zambiri 0 °, 30 °, ndi 60 °)

Kamera iliyonse imakhala ndi makina odziyimira pawokha osinthika a LED omwe amatha kuphatikiza mafunde angapo (kuwala kofiyira, kuwala kwabuluu, kuwala koyera, etc.)

Chotsani mawonekedwe akhungu kudzera pazithunzi zamitundu ingapo ndikuwongolera kudalirika kwazinthu zovuta (BGA, QFN, etc.)

2.2 Image processing kuyenda

Kupeza zithunzi: makamera atatu kuwombera molumikizana

Kukonzekera kwazithunzi: zoyera zodziwikiratu, kukonza mthunzi, kuthetsa phokoso

Kutulutsa mawonekedwe: kuzindikira m'mphepete, kusanthula kwa grayscale, kufananiza ndi mawonekedwe

Kutsimikiza kwachilema: gulu lanzeru kutengera malamulo ndi ma algorithms a AI

Zotsatira: Chizindikiro cha NG, kuyika kwa data ku MES

3. Mafotokozedwe aukadaulo

Zotsatira za Project

Kuzindikira kulondola Kuchepa kwapang'onopang'ono 0201, kulondola kolumikizana kwa solder ± 15μm

Liwiro lozindikira Kuchuluka kwa masekondi 0.05/pozindikira (mtengo wamalingaliro)

PCB kukula Zolemba malire 510×460mm (mtundu muyezo)

Kamera dongosolo 3 × 5 megapixel CCD, chimango mlingo 30fps

Makina opangira kuwala kwamitundu yambiri ya LED yophatikizira kuwala (wofiira/buluu/woyera/IR)

Bwerezani kulondola ± 5μm

Kuyankhulana kwa SECS/GEM, TCP/IP, RS-232

4. Zinthu zazikulu

4.1 Kuzindikira kwamakamera atatu

0 ° kamera: zindikirani mbali ya thupi ndi logo

30 ° kamera: zindikirani mizere yolumikizana ndi solder

Kamera ya 60 °: zindikirani malo olumikizana ndi solder

Kuphatikizika kwa data koyang'ana katatu, ndikuchotsa mawonekedwe akhungu amtundu umodzi

4.2 Algorithm yozindikira mwanzeru

Mtundu wophunzirira mozama: phunzirani zokha za zitsanzo za OK/NG

Kusintha kwamphamvu kolowera: konzani magawo molingana ndi kusintha kwa ndondomeko

Muyeso weniweni: werengera magawo a 3D monga kutalika kwa gawo ndi voliyumu kudzera pazithunzi

4.3 Kusintha koyenera kwa kupanga

Mapangidwe amtundu wapawiri: kuzindikira ndi matabwa apamwamba ndi apansi amachitidwa nthawi imodzi

Kusintha kwachangu kwa mzere: nthawi yosinthira pulogalamu <30 masekondi

Kuyang'ananso mwanzeru: ikani nokha mfundo zokayikitsa kuti muchepetse kuyang'ananso pamanja

5. Njira zopewera kugwiritsa ntchito

5.1 Zofuna zachilengedwe

Kutentha: 20 ± 5 ℃

Chinyezi: 40-70% RH

Kugwedezeka: <0.5G

Kuyatsa: Pewani kuwala kwamphamvu kwachindunji

5.2 Mafotokozedwe a ntchito

Njira yoyatsira:

Kutenthetsa kwa mphindi 10

Pangani calibration yokha

Tsimikizirani kufanana kwa gwero la kuwala

Kuyang'ana tsiku ndi tsiku:

Sampling maola 2 aliwonse kutsimikizira kukhazikika kwa kuyendera

Nthawi zonse yeretsani zikhomo zonyamula katundu

Kasamalidwe ka pulogalamu:

Laibulale yoyendera yokhazikika iyenera kukhazikitsidwa yamitundu yatsopano

Nthawi zonse sungani magawo a pulogalamu

6. Zolakwa wamba ndi kusamalira

Khodi yolakwika Kufotokozera molakwika Solution

E101 Kulumikizana kwa kamera kutha 1. Yang'anani chingwe cholumikizira kamera

2. Yambitsaninso mphamvu ya kamera

E205 Kuwala kolakwika 1. Yang'anani mphamvu yamagetsi ya LED

2. Bwezerani gawo lolakwika la LED

E307 Motion control cholakwika 1. Yang'anani pa servo drive

2. Yeretsani njanji yowongolera

E412 Image processing timeout 1. Konzani magawo oyendera

2. Sinthani mtundu wa mapulogalamu

E503 Kusokoneza kulumikizana kwa data 1. Yang'anani kulumikizidwa kwa netiweki

2. Yambitsaninso ntchito yolumikizirana

7. Njira yosamalira

7.1 Kusamalira tsiku ndi tsiku

Tsiku ndi Tsiku:

Yeretsani zenera la kuwala (gwiritsani ntchito zida zapadera zoyeretsera)

Onani kuthamanga kwa mpweya (ngati kuli kotheka)

Tsimikizirani kulimba kwa lamba wa conveyor

Sabata iliyonse:
