1. Inzwa yokucindezela yeUmshini we-SMT
Khetha bese ubeka umshini, kufaka phakathi amasilinda ahlukahlukene kanye nama-vacuum generator, anezidingo ezithile zokucindezela komoya, okuphansi kunokucindezela okudingwa yimishini, umshini awukwazi ukusebenza ngokujwayelekile.Izinzwa zokucindezela zihlale ziqapha izinguquko zengcindezi, uma zingajwayelekile, okungukuthi, i-alamu efika ngesikhathi, zikhumbuza opharetha ukuthi abhekane nakho kusenesikhathi.
2. Inzwa yokucindezela engalungile yomshini we-SMT
Iumlomo wombhobhowomshini we-SMT udonsa izingxenye ngomfutho ongemuhle, owakhiwa i-negative pressure generator (i-jet vacuum generator) kanye nenzwa ye-vacuum.Uma ukucindezela okungalungile kunganele, izingxenye ngeke zimukelwe.Uma zingekho izingxenye ku-feeder noma izingxenye zinamathele esikhwameni sezinto ezibonakalayo futhi zingakwazi ukumuncwa, umbhobho wokumunca ngeke umuncwe.Lezi zimo zizothinta ukusebenza okuvamile komshini.Inzwa yokucindezela okunegethivu ihlale iqapha ukuguqulwa kokucindezela okungekuhle, futhi uma izingxenye zokudonsa noma zokumunca zingatholakali, inganikeza i-alamu kusenesikhathi ukukhumbuza opharetha ukuthi amiselele okuphakelayo noma ahlole ukuthi ingabe uhlelo lokucindezela okunegethivu lombhobho wokumunca luvinjiwe yini.
3. Inzwa yesikhundla yomshini we-SMT
Ukudluliswa nokumiswa kwebhodi eliphrintiwe, okuhlanganisa ukubala kwe-PCB, ukutholwa kwesikhathi sangempela kwekhanda le-SMT nokunyakaza kwebhentshi lokusebenzela, nokunyakaza komshini osizayo, kunezidingo eziqinile zesikhundla, okudingeka zifezwe izinhlobo ezihlukahlukene zezinzwa zokuma.
4. Inzwa yesithombe yomshini we-SMT
Inzwa yesithombe se-CCD isetshenziselwa ukubonisa isimo sokusebenza somshini we-SMT ngesikhathi sangempela.Ingakwazi ukuqoqa zonke izinhlobo zamasiginali wesithombe adingekayo, okuhlanganisa indawo ye-PCB nosayizi wedivayisi, futhi yenze ukulungisa kanye ne-SMT yekhanda lesichibi kuqedelwe ngokuhlaziywa kwekhompyutha nokucutshungulwa.
5. Inzwa ye-laser yomshini we-SMT
I-Laser isetshenziswe kabanzi emshinini we-SMT, ingasiza ukwahlulela izici ze-coplanar zezikhonkwane zedivayisi.Uma ugijimela endaweni yenzwa ye-laser eqapha idivayisi ehlolwayo, ekhishwa yi-laser beam kumaphini we-IC kanye nokuboniswa kwe-laser kumfundi, uma ubude be-beam obubonisiwe bufana ne-beam, i-coplanarity yedivayisi ifanelekile, uma kungafani, kungenxa yokusonteka kuphini, yenza ubude be-beam bokukhanya, inzwa ye-laser ukukhomba iphinikhodi yedivayisi ayinamaphutha.Futhi, inzwa ye-laser ingakwazi ukubona ukuphakama kwedivayisi, okunganciphisa isikhathi sokuhola.
6. Inzwa yendawo yomshini we-SMT
Lapho umshini we-SMT usebenza, ukuze unamathele inhloko yokusebenza okuphephile, ngokuvamile ekhanda lendawo yokunyakaza ifakwe izinzwa, ukusetshenziswa kwesimiso se-photoelectric ukuqapha indawo yokusebenza, ukuvimbela ukulimala kwezinto zangaphandle.
7. Namathisela inzwa yokucindezela yesihloko sefilimu
Ngokuthuthukiswa kwejubane nokunemba kwesichibi, "amandla okumunca kanye nokukhululwa" kwekhanda lokunamathisela ukuze anamathisele izingxenye ku-PCB aya ngokuya edingeka, okuvame ukubizwa ngokuthi "umsebenzi wokufika othambile we-Z-axis".Ibonakala ngezici zomthwalo wenzwa yokucindezela kwehholo kanye ne-servo motor.Lapho ingxenye ibekwe ku-PCB, izonyakaziswa ngaleso sikhathi, futhi amandla ayo okudlidliza angadluliselwa ohlelweni lokulawula ngesikhathi, bese ibuyiselwa ekhanda le-patch ngomthetho wohlelo lokulawula, ukuze kubonakale z-axis umsebenzi wokufika othambile.Lapho ikhanda lesichibi elinalo msebenzi lisebenza, linikeza umuzwa wokuba bushelelezi nokukhanya.Uma ukubhekwa okwengeziwe kwenziwa, ukujula kweziphetho ezimbili zengxenye ecwiliswe ku-solder paste kucishe kufane, futhi okuzuzisa kakhulu ukuvimbela ukuvela "kwetshe lesikhumbuzo" nokunye ukukhubazeka kokushisela.Ngaphandle kwenzwa yokucindezela, kungase kube nokugudluka ukuze undize.
