Chii chinonzi Automated Optical Inspection (AOI)?

Kuongororwa Kwemagetsi Kwemagetsi (AOI) kwave tekinoroji inokosha zvikuru mumunda weSurface Mount Technology ( SMT ) yekugadzira mabhodhi edunhu akadhindwa ( PCB ), kunyanya munzvimbo dzine maindasitiri ehunyanzvi hwepamusoro seUSA. Iyi tekinoroji inobatsira zvikuru mukuchengetedza mwero wepamusoro wekudzora mhando, nokudaro ichivimbisa kuvimbika uye kushanda kwemaPCB muzvishandiso zvakasiyana-siyana, kubva kumagetsi emagetsi evatengi kusvika kumidziyo yemuchadenga yakakosha uye yekurapa.

Nhanganyaya kuAOI muSMT PCB Gungano

Masisitimu eAOI anogadzirisa maitiro ekutarisa nemaziso ayo aiitwa nemaoko, zvichipa nzira yekuongorora inokurumidza, yakarurama, uye inoenderana. Kugadzira otomatiki uku kunonyanya kukosha munzvimbo dzekugadzira dzakasanganiswa zvakanyanya uko magadzirirwo akasiyana-siyana ePCB nezvikamu zvinogona kuva zvakawanda, uye nzvimbo yekukanganisa iri shoma.

Zvikamu Zvikuru zveAOI Systems

• High-Resolution Makamera: Michina yeAOI ine imwe kana anopfuura makamera akakwira-resolution anotora mifananidzo yePCB. Aya makamera anogona kunge akamira kana nhare, zvichienderana nehurongwa hwekugadzira. Mamwe masisitimu anoshandisa akawanda makamera kutora mifananidzo kubva kumakona akasiyana kana kuongorora nzvimbo dzakasiyana dzebhodhi panguva imwe chete.
• Lighting Systems: Kuvheneka kwakanaka kwakakosha kuAOI. Masisitimu ekuvhenekesa akasiyana (semuenzaniso, ma LED arrays) anoshandiswa kuvhenekera PCB kubva kumakona akasiyana, kuwedzera kuoneka kwezvikamu, majoini ekutengesa, uye hurema hunogona kuitika. Matanho ekuvhenekesa, akadai seyakajeka-munda, rima-munda, uye mwenje weparutivi, unobatsira kuratidza marudzi akasiyana ezvimiro uye zvikanganiso.
• Software algorithms: Mwoyo wekuedzwa kweAOI uri musoftware yayo, inoongorora mifananidzo yakatorwa. Yepamberi algorithms inoenzanisa iyo mifananidzo inopesana neyakafanotsanangurwa maitiro kana yedhijitari "goridhe bhodhi" - referenzi modhi yeiyo yakakwana PCB inofanirwa kutaridzika sei. Aya maalgorithms anogona kuona kuwanda kwehurema nekuongorora maumbirwo, mavara, uye misiyano.

Mashandiro AOI

1. Setup uye Calibration: Kuedza kusati kwatanga, chirongwa cheAOI chinofanirwa kurongedzwa uye kurongwa nemitezo yekuongorora yePCB iri kugadzirwa. Izvi zvinosanganisira kuisa iyo dhizaini yakatarwa, chikamu raibhurari, uye inogamuchirika mazinga ekushivirira kune akasiyana maficha.
2. Kutora Mufananidzo: MaPCB paanopfuura nemuchina weAOI, makamera anotora mifananidzo kubva kumakona akasiyana. Iyi yekufungidzira yakazara inovimbisa kuti sisitimu inogona kuongorora zvese zvebhodhi, kusanganisira kuvapo kwechikamu, kurongeka kwechokwadi, solder mhando, nezvimwe.
3. Ongororo Yemifananidzo: Mifananidzo yakatorwa inozoongororwa nesoftware. Ichishandisa yakaoma algorithms, iyo sisitimu inotarisa kune akasiyana siyana anogona kukanganisa.
4. Kuzivisa uye Mhinduro: Mushure mekuongorora, masisitimu eAOI anoburitsa mishumo ine hudzamu inotaridza kukanganisa kwakaonekwa. Iyi data yakakosha pakuongorora nyaya dzemaitiro uye kuita matanho ekugadzirisa. Inopawo mhinduro yakakosha yekuenderera mberi kwekuvandudzwa kwemaitiro ekugadzira.

Advanced Technologies Hunoshandiswa muAOI masisitimu

Kufungidzira kwe2D ne3D: Tekinoroji yekufungidzira kwe3D, senge laser triangulation kana structured light, inowedzera kufungidzira kwe2D kwechinyakare nekupa ruzivo rwakadzama pamusoro pehurefu nehuwandu hwezvikamu uye majoini e solder. Izvi zvinoita kuti pave nekuona kwakanyatsojeka zvikanganiso zvine chekuita nekuiswa kwezvikamu uye mhando ye solder.

Peji rino ndiro gwara reAOI rine tsananguro. Kuti uone mashandisirwo anoitwa AOI mukugadzirwa kwePCB nePCBA, shandisa AOI pakuongorora PCB nePCBA ; kuti uwane kuongororwa kwakakura uye kudzora magwaro, ongorora maitiro eHighleap ePCB.

Kudzidza Kwemuchina neAI: Mamwe masisitimu eAOI anosanganisira maalgorithms ekudzidza kwemuchina anovandudza kuona zvikanganiso nekufamba kwenguva. Masisitimu aya anodzidza kubva mukuongororwa kwekare, zvichivandudza kugona kwawo kusiyanisa pakati pezvikanganiso zvechokwadi uye misiyano inobvumirwa mukugadzirwa.

Kubatanidzwa neMidziyo yeSMT: Masisitimu emazuva ano eAOI anowanzo batanidzwa nemimwe michina yeSMT, zvichibvumira mhinduro uye kugadzirisa panguva chaiyo. Kubatanidzwa uku kunobatsira mukuona matambudziko nekukurumidza uye kuderedza kuwanda kwezvikanganiso zviri kuitika panguva yekubatanidza PCB.

Mhando Dzakakanganiswa

Kuwanda kwemasisitimu eAOI kunobvumira kuona kwakasiyana kwakasiyana-siyana:

• Zvisipo Zvikamu: Zvinozivikanwa kuburikidza ne 2D imaging, ine 3D imaging ichipa kumwe kujeka mumamiriro epasi-musiyano.
• Polarity uye Chikamu Nhamba: Inosimbisa kuti zvikamu zvakaiswa negwara chairo uye rinoenderana nebhiri rezvinhu.
• Positional Defects: Inoona machinjo kana kusarongeka, ichiisa magiredhi zvinoenderana neyakagadzika IPC zviyero.
• Physical Anomalies: Zvakadai semakuva, akabhenda kana kusimudzwa anotungamira, uye akasiyana-siyana akaremara (semuenzaniso, akavhurika maseketi, mapfupi, asina kukwana solder).
• Coplanarity Verification: Yakakosha pakuona kupfava kwezvinhu zvakakosha senge BGAs, uchishandisa 3D imaging yechokwadi.

AOI Mukuita paHighleap Electronic

PaHighleap Electronic, inofungidzira yakakwirira-musanganiswa PCB inogadzira nzvimbo, AOI chikamu chakakosha chemaitiro ekusimbisa. Iyi tekinoroji inoshandiswa post-SMT pick-and-place uye reflow soldering maitirwo ekuona uye mureza chero akaremara mabhodhi ekugadzirisa zvakare, ichipa yakajeka mifananidzo yezvinhu zvakaonekwa kuti zvigadziriswe nekukurumidza. Pamusoro pazvo, AOI yakakosha pakuongorora paste, kuona kuvharika kwakanaka uye kunaka isati yaenderera mberi nekuisa chikamu, izvo zvakakosha pakubudirira kwekutanga kuseta basa uye kuunzwa kwemabhechi matsva emasoja.
