Ukugcinwa kweumshini wokugcwalisa i-wave okhethiwe
Emishinini ekhethiwe ye-wave soldering, ngokuvamile kunamamojula amathathu okulungisa: imojula yokufafaza i-flux, imojula yokushisa, kanye nemojula ye-soldering.
1. Ukugcinwa nokugcinwa kwemojula ye-Flux yokufafaza
Ukufafaza kwe-Flux kuyakhethwa kujoyinti ngalinye le-solder, futhi ukugcinwa okufanele kungaqinisekisa ukusebenza kwayo okuzinzile nokunemba.Phakathi nenqubo yokufafaza, ngokuvamile kuba nenani elincane lokugeleza elisele ku-nozzle, futhi i-solvent yayo izoshabalala futhi ikhiqize ukufingqa.Ngakho-ke, kuyadingeka ukuhlanza umlomo wombhobho kanye nendawo ezungezile ngendwangu engenalo uthuli ecwiliswe otshwaleni noma kwezinye izixazululo zemvelo ngaphambi kokuba ukukhiqizwa ngakunye kuqale ukukhipha izinsalela eziphuma emlonyeni ukuze kugwenywe ukuvinjwa umlomo wombhobho futhi kubangele ukunamathela okungekho emthethweni. amabhodi ambalwa okuqala ekukhiqizeni okuqhubekayo.
Ukugcinwa okuphelele kwe-nozzle kuyadingeka kulezi zimo ezintathu ezilandelayo: ukusebenza okuqhubekayo kwemishini kuze kufike emahoreni angu-3000;ukusebenza okuqhubekayo kwemishini unyaka owodwa;kanye nokuqhubeka kokukhiqiza ngemva kwesonto elilodwa lokungasebenzi.Ukugcinwa okuphelele kufanele kunake ukuhlanzwa kwangaphakathi kwe-nozzle, futhi idivayisi yayo ye-atomization ihlanzwa kangcono ngokusebenzisa ukuhlanza kwe-ultrasonic.Ngaphambi kokusebenzisa ukuhlanza kwe-ultrasonic, isixazululo sokuhlanza siyashiswa sibe ngu-65 ° C, esingathuthukisa ikhono lokukhipha ukungcola.Ngesikhathi esifanayo, izingxenye zamapayipi kanye nokuvala zemojuli yokufafaza kufanele futhi zihlolwe kahle.
2. Ukugcinwa kwemojula yokushisa kuqala
Ngaso sonke isikhathi ngaphambi kokuba umshini uvule futhi usetshenziswe, imojula yokushisa ngaphambi kwesikhathi kufanele ihlolwe ukuze kubonakale ukuthi ingilazi yokushisa ephezulu iphukile futhi iphukile, futhi uma kunjalo, kufanele ishintshwe ngesikhathi.Uma kungenjalo, udinga ukusebenzisa indwangu kakotini ethambile ecwiliswe emanzini noma etshwaleni ukuze usule ukungcola okungaphezulu kwayo.Uma kunezinsalela ze-flux ezinenkani ebusweni bayo, ungasebenzisa isisombululo esikhethekile sokuhlanza ukuhlanza ubuso baso.
Ku-module ye-preheat, i-thermocouple isetshenziselwa ukukala izinga lokushisa lokushisa futhi inendima ebaluleke kakhulu.Ngokuvamile, i-thermocouple ifakwe ngokuhambisana neshubhu lokushisa.Ngesikhathi sokusetshenziswa, uma i-thermocouple kanye ne-tube yokushisa ingahambisani, hlola ukuthi yonakele yini, bese ubuyisela i-thermocouple ngesikhathi lapho kudingeka.
3. Ukugcinwa kwe-welding module
Imodyuli ye-Welding iyimodyuli enembile kakhulu futhi ebaluleke kakhulu emshinini wokukhetha, ngokuvamile itholakala engxenyeni engenhla yemodyuli yokushisa umoya oshisayo, phakathi nendawo yemodyuli yokuthutha kanye nengxenye engezansi ye-welding module, isimo sayo sokusebenza sithinta ngokuqondile. izinga lokushisela ibhodi lesifunda, ngakho ukugcinwa kwalo nakho kubaluleke kakhulu.
Lapho i-wave iqala ukugijima, uma i-nozzle ingamanzi ngokuphelele yi-solder, ingxenye engamanzi izovimba ukugeleza kwe-solder, futhi ukuzinza kwegagasi nokunemba kwe-welding kuzothinteka kakhulu.Ngalesi sikhathi, i-nozzle kufanele ikhishwe ngokushesha, ngaphandle kwalokho i-nozzle izokhishwa ngokushesha futhi ichithwe.
Inqubo ye-Wave soldering izokhiqiza inani elithile le-oxide (ikakhulukazi ithini umlotha kanye ne-dross), lapho liningi kakhulu lizothinta ukuhamba kwe-tin, kuyimbangela eyinhloko ye-solder engenalutho kanye nebhuloho, kodwa futhi ivimbe imbobo ye-nitrogen, inciphise indima. yokuvikelwa kwe-nitrogen, ukuze i-oxidation esheshayo ye-solder.Ngakho-ke, ohlelweni lwe-welding, qaphela ukukhishwa kwe-tin ash dross, kodwa futhi uhlole ukuthi i-outlet ye-nitrogen ivinjiwe.
