Isakhiwo esikhulu somshini we-SMT

Uyazi ukwakheka kwangaphakathi kweumshini wokukhweza phezulu?Bona ngezansi:

I-NeoDen4 Khetha bese ubeka umshini

I. Umshini wokugcwalisa i-SMTifreyimu

Uhlaka luyisisekelo somshini wokukhweza, zonke izinhlobo zokudlulisa, ukubeka, izindlela zokudlulisela zigxilwe ngokuqinile kuwo, zonke izinhlobo zokuphakela zingabekwa.Ngakho-ke, ifreyimu kufanele ibe namandla okusebenza anele kanye nokuqina, umshini wamanje wokukhweza ungahlukaniswa cishe ube uhlobo lokuphonsa okubalulekile kanye nohlobo lwensimbi yokushisela izigaba ezimbili.

II.Indlela yokudlulisa kanye nenkundla yokusekela yomshini wokuhlanganisa we-SMT
Umsebenzi wendlela yokudlulisa ukuthumela i-PCB edinga isichibi endaweni enqunywe kusengaphambili, bese usithumela enqubweni elandelayo ngemva kokuqedwa kwesichibi.Isidlulisi siyisistimu yokudlulisa ibhande elincanyana kakhulu elibekwe kuthrekhi, ngokuvamile emaphethelweni ethrekhi.

III.Amakhanda emishini ye-SMT
Ikhanda lokunamathisela liyingxenye ebalulekile yomshini wokunamathisela.Ngemva kokuthatha izingxenye, ingakwazi ukulungisa ngokuzenzakalelayo isikhundla ngaphansi kwesistimu yokulungisa futhi inamathisele ngokunembile izingxenye endaweni ekhethiwe.Ukuthuthukiswa kwekhanda le-patch kuwuphawu lokuqhubeka komshini wokunamathisela.Umshini wokuchibiyela uthuthukiswe kusukela ekuqaleni kwekhanda elilodwa kanye nokuqondanisa komshini ukuya ekuqondaneni kwe-multi-head optical.

IV.Isiphakeli somshini we-SMT
Umsebenzi wesiphakeli ukuhlinzeka ngezingxenye ze-chip ze-SMC/SMD kukhanda le-chip ngokwemithetho ethile nokuhleleka, ukuze sicoshe ngokunemba nangokufanele.Ithatha inombolo enkulu kanye nesikhundla emshinini we-chip, futhi iyingxenye ebalulekile yokukhethwa komshini we-chip kanye nokuhlelwa kwenqubo ye-chip.Ngokuya ngephakethe le-SMC/SMD, okuphakelayo kuvame ukutholakala ku-strip, ishubhu, idiski kanye nefomu lenqwaba.

V. Inzwa ye-SMT
Umshini Mounting ifakwe ezihlukahlukene izinzwa, ezifana inzwa yokucindezela, negative inzwa yokucindezela kanye inzwa isikhundla, kanye ngcono ohlakaniphile Mounting umshini, kungenziwa ingxenye yokuhlola ukusebenza kagesi, njalo ukuqapha ukusebenza evamile umshini.Uma kusetshenziswa izinzwa eziningi, izinga lobuhlakani be-SMT liya phezulu.

VI.I-XY kanye ne-Z/θ isistimu yokubeka i-servo ye-SMT
Uhlelo lwe-Fuction XY positioning luwukhiye womshini we-SMT, futhi luyinkomba eyinhloko ekuhloleni ukunemba komshini we-SMT, okuhlanganisa indlela yokudlulisa i-XY nohlelo lwe-XY servo, kunezindlela ezimbili ezivamile zokusebenza: uhlobo olulodwa ukusekela ukuvulwa, ukuvulwa kufakwe kumzila wesitimela we-X, u-X uqondise endleleni ye-Y ukuze ufeze yonke inqubo ye-patch ekuqondeni kwe-Y, lolu hlobo lwesakhiwo emshinini we-SMT onemisebenzi eminingi ukuze ubone okwengeziwe;Okunye ukusekela iplatifomu ephethe i-PCB futhi uqaphele i-PCB ihamba ngendlela ye-XY.Lolu hlobo lwesakhiwo luvame ukubonakala emshinini wokukhweza wekhanda ojikelezayo wohlobo lwe-turret.Inhloko yokukhweza yomshini wokukhweza we-turret onesivinini esikhulu yenza kuphela ukunyakaza okuzungezayo, futhi incike ekuhambeni okuvundlile kwesiphakeli kanye nokunyakaza kwendiza enyakazayo ye-PCB ukuze kuqedelwe inqubo yokukhweza.Isistimu yokuma ye-XY engenhla ingeyesakhiwo sesitimela esihambayo.

VII.I-Optical Identification System yomshini wokukhweza
Ukuvulwa kokuthunyelwe ngemva kokumunca izingxenye, ukuthwebula kwekhamera ye-CCD yezingxenye, futhi kuhunyushelwe kusignali yesithombe sedijithali, ngemva kokuhlaziywa kwekhompyutha kobukhulu bejiyomethri bezingxenye nesikhungo sejiyomethri, futhi kuqhathaniswa nohlelo lokulawula lwedatha, ukubala isikhungo somlomo wokumunca esinezingxenye Δ X, Δ Y kanye nephutha le-Δ theta, kanye nempendulo efike ngesikhathi kusistimu yokulawula, iqinisekisa ukuthi amaphinikhodi wezingxenye kanye ne-PCB solder kuyagqagqana.
