Muindasitiri yemagetsi, iyo yakadhindwa redunhu bhodhi (PCB) ndicho chikamu chikuru chezvakasiyana zvigadzirwa zvemagetsi. Iyo solder yemhando yezvikamu paPCB inokanganisa zvakananga kuita kwechigadzirwa. Naizvozvo, kuongororwa kwemhando uye kuyedzwa kwemabhodhi ePCB ndiko kutonga kwemhando yevagadziri vePCB application. Chibatanidza chakakosha. Parizvino, mazhinji ePCB soldering yemhando yebasa rekuongorora inoitwa kuburikidza nemanyorero ekuona yekuongorora. Kufurira kwezvinhu zvevanhu kuri nyore kupotsa uye kuona zvisirizvo.

Naizvozvo, iyo PCB indasitiri inoda nekukurumidza pamhepo otomatiki yekuona yekuongorora, uye zvigadzirwa zvekunze zvinodhura zvakanyanya. Zvichienderana nemamiriro ezvinhu aya, nyika yakatanga kuvandudza izvi. Detection Systems. Iri bepa rinonyanya kuongorora kuzivikanwa kwePCB board welding defects: kuzivikanwa kwemavara mhete kuramba, kuzivikanwa kwechikamu chinodonha welding uye kuzivikanwa kwecapacitor polarity.

Iyo nzira yekugadzirisa iri mupepa rino ndeyekubatanidza nzira yekuenzanisa yekuenzanisa uye isiri-referenzi yekuenzanisa nzira yekuwana PCB bhodhi mufananidzo kubva kudhijitari kamera, uye kushandisa nzira dzekumisikidza mufananidzo, preprocessing yemifananidzo uye kuzivikanwa kwemufananidzo, kudhirowa kwechinhu kuti uone otomatiki yekuona basa. Kuburikidza nekuedza kwemifananidzo yakawanda yePCB, nzira yekumisikidza yePCB mifananidzo inovandudzwa kuti iwane chaiyo yekumisikidzwa kwemufananidzo.

Iyo yakajairwa chikamu chekuputsika chikamu chakakosha. Iri ndiro bhodhi redunhu uye bhodhi rakajairwa. Ita nhanho yekutanga yemutambo chaiwo. Muchikamu chekugadzirisa chifananidzo, nzira itsva yekugadzirisa geometric inoshandiswa kugadzirisa mufananidzo kuti uwane mifananidzo yePCB yakarurama uye mapikisi chaiwo ekubatanidza kwechikamu chimwe nechimwe, uye kuita mufananidzo binarization, median filtering, kumucheto kuona uye dzimwe nzira kuti uwane Kuzivikanwa kwakanakisisa. Mumufananidzo unotevera kucherechedzwa kwechifananidzo chemhedzisiro, maficha anotorwa kubva pamufananidzo mushure mekugadzirisa, uye nzira dzakasiyana dzekucherechedzwa dzinogamuchirwa kune dzakasiyana welding defects.

Kushandisa nzira dzechiverengero kuburitsa yakaringana simba reruvara kuti unyatso ratidza kupikisa mhete yeruvara, uye kugadzirisa kuzivikanwa kwekudzivirira mhete yeruvara kubva pachikamu chemavara kusvika pakuzadza kwakazara. Nezve geometric maitiro epolar capacitor, iyo geometric identification nzira inoshandiswa pakushandiswa kwechikamu chekudonha welding. Iyo probabilistic recognition nzira yakawana mhedzisiro yakanaka yekuzivikanwa. Naizvozvo, iyi nzira ine yakanaka referensi kukosha kweiyo otomatiki kuzivikanwa kwePCB chirema chekuonekwa muChina.
