In Umshini wokufaka we-SMDuhlelo lombono singakwazi ukucacisa ngokunembe kakhudlwana izingxenye zamanje, amabhodi wesifunda nomaI-SMT suction nozzleisikhundla, sithembele ohlelweni lokuqaphela okubonakalayo singanikeza ukubekwa okunembe kakhudlwana komshini wokubeka bese uqonda ukuthi le sistimu yakhiwe kanjani?
1. Kukhona ikhamera yekhanda ngenhla kwesikhweli, ngokuvamile isebenzisa ubuchwepheshe benzwa yolayini, ngesikhathi sokucosha nokuhamba ngekhanda lokukhweza ingakwazi ukubona izingxenye endaweni emisiwe.Ingathuthukisa ukunemba okuningi kokubeka nokusebenza kahle.Ngokuvamile, uhlelo lwakhiwe amamojula amabili: enye imojula yomthombo wokukhanya eyakhiwe umthombo wokukhanya kanye nelensi.Ilensi yomthombo wokukhanya ihlanganisa imojuli yokudlulisa ukukhanya.
2. Kukhona ikhamera yokubuka ephezulu ngaphansi kwesikhweli, singayisebenzisela ukubona indawo yengxenye, lapho ikhamera yesistimu yokuhlonza ifakiwe phakathi kwendawo yokuthwebula nendawo yokufaka, khona-ke singakwazi ukwenza kanyekanye ukutholwa kwevidiyo nokucubungula lapho usebenzisa. isihloko sevidiyo, ngaleyo ndlela sifinyeze isikhathi sokufaka isikhwezi.
3. Uhlelo lokuqondanisa i-laser singasebenzisa lesi simiso ngosayizi nokuma kwezingxenye ezilinganisiwe ohlelweni lomshini wokukhweza.Inzuzo ukuthi ukuqondanisa kuyashesha futhi kunembile, kodwa okubi ukuthi akukwazi ukwenza ukuhlolwa kwephini kumaphini kanye nezingxenye ezinamaphini aqinile.
Umbono System ofI-NeoDen4 desktop pick and place machine
II-NeoDen4 inesistimu yokunemba ephezulu, enamakhamera amabili.Amakhamera enziwe iMicron Technology futhi aqondaniswe ngokunembile nemibhobho esebenzisa uhlelo olulodwa oluhlanganisiwe lokucushwa/ukusebenza olulayisha amandla.
Ikhamera ebheke phansi:
Ekhanda kusetshenziselwa ukunemba kwendawo yokuphakelayo kanye nezindawo zokubeka ze-PCB.Eya phansiikhamera ebukayo iphinde iqinisekise ukubekwa kwebhodi okufanele (futhi inxephezele ngokuma kwebhodi elincaneokunganembile) ngokuqondanisa ngokuzenzakalela imibhobho kumafiducial amaningi ebhodini ngaphambi kokuqala ukusebenza kwangempela kokukhetha nendawo.Uma izixhumanisi sezimisiwe, amamotho enyathela e-semi-closed-loop ayakwazi ukuphinda lezi zindawo zibe nokunemba okungu-20µm ngaphandle kwesidingo esengeziwe sale khamera.
Ikhamera ebheke phezulu:
Itholakala ngakwesokudla komshini.Uma inikwe amandla, le khamera iqinisekisa kuqala ukuthi ingxenye inamathiselwe ku-nozzle efanele.Uma ikhamera ithola ukungabikho kwengxenye, umshini uzokwenza imizamo eyengeziwe emibili yokukhetha ingxenye ngaphambi kokubuza umsebenzisi iziqondiso ezengeziwe.Uma ingxenye isiqinisekisiwe ngokuthi "ikhethiwe", ikhamera iqinisekisa indawo yayo ngokuhlobene nombhobho.Ngenxa yokuthi ama-SMD mancane futhi alula, futhi abanjwa ngokukhululeka kuphela emaphaketheni awo, kungase kube nokuhlukahluka okukhulu endaweni yangempela yengxenye lapho ifika endaweni “khetha” futhi iphakanyiswa umlomo wombhobho.Isistimu yombono ibala umehluko phakathi kwendawo ekahle nengokoqobo (kokubili i-XY nokujikeleza), bese ilungisa noma yiliphi iphutha ngaphambi kokubeka ingxenye ngokunembile.Ngenxa yokuthi isistimu yombono ihlale ilungisa ngisho namaphutha amancane endaweni yesi-2 emlonyeni, izingxenye zephimbo elihle kakhulu (kuze kufike ku-0201) zingabekwa ngokunemba okuphindaphindwayo uma sekuhlonzwe izixhumanisi ezifanele.Ngalokhu kuqonda okuyisisekelo, izithombe ezilandelayo zembula izingxenye eziyisisekelo ze-Neoden4.
