SMTkhetha kwayeindawo umatshiniekwaziwa ngokuba "ngumatshini wokubeka" kunye "nenkqubo yokubeka umphezulu", sisixhobo sokubeka izinto zokubeka umphezulu ngokuchanekileyo kwi-PCB solder plate ngokuhambisa intloko yokubeka emva komatshini wokukhupha okanyeumshicileli westencilkumgca wemveliso.Kwakhona sesona sixhobo siphambili kumgca wokuvelisa we-SMT.Kodwa kutheniumoya compressorzisetyenziswe xa umatshini wokubeka usebenza
Oku kubandakanya amacandelo aphambili omatshini wokubeka: i-pneumatic kunye ne-vacuum system.
Kumatshini wokubeka, iindawo zomoya ezibandakanya ipleyiti yokumisa kunye nesixhobo sokuluka, inkxaso yepleyiti, ukutshintsha umbhobho wokufunxa (ukuvulwa nokuvalwa kwepleyiti yesilayidi kunye nokunyuswa kunye nokuphakanyiswa kwetshintshi xa kutshintshwa umbhobho wokufunxa), ukuthathwa kwentloko kunye nokubekwa (vacuum). Kusekwe xa ilori ithathwa, kwaye ukuvuthela kuyabonelelwa xa kubekwe) zonke ziyafuneka.Kwakhona unalo iiletshi zokhuseleko lomatshini wokubeka zikwasebenzisa imo ye-pneumatic.Ezinye iimathiriyeli zikwanomoya, ezifana ne-pneumatic feeders, i-tubular feeders kunye ne-mobile feeders.
Oku kulandelayo, umatshini wokubekwa kwenkqubo yomoya oza kuqaliswa.Okokuqala, umoya woxinzelelo kumatshini womatshini kufuneka uhlanjululwe kwaye uhlanjululwe ukuze uqinisekise umoya ococekileyo kunye nowomileyo, ukuze ungachaphazeli ukusebenza okuqhelekileyo komatshini okanye ubangele umonakalo;Ukuhamba okwaneleyo kunye noxinzelelo nako kufuneka kuqinisekiswe.Umatshini wokubeka ngokwawo kufuneka uxhotyiswe ngesethi nganye yomthombo womoya, kubandakanywa ivalve yokulawula uxinzelelo, i-gauge ye-pressure gauge kunye ne-filter, njl njl. Uxinzelelo luhlengahlengiswa ngokubanzi malunga ne-85PSI.Uninzi koomatshini nabo banezinzwa zoxinzelelo oluphantsi, kwaye xa uxinzelelo luphantsi kakhulu (ngokuqhelekileyo malunga ne-70PSI), umatshini awuyi kukwazi ukubuyela kwi-zero okanye usebenze.
Umzekelo: ukuba uvula umgca, umatshini wokushicilela oyisemi-automatic, umatshini we-SMT oyi-0.5Mpa, kunye neAOIumatshini, kunye nesibhamu somoya ngokuqhelekileyo ukuhlamba i-mesh yensimbi, luhlobo luni lwe-compressor yomoya olulungileyo, ukuba imigca emibini kunye nendlela yokujongana nayo?
Ngeziqwenga ezi-3 ukuya kwezi-4 zecompressor yomoya, khetha i-screw air compressor, unikezelo lomoya oluzinzileyo ingxolo ecocekileyo, unokwandisa ubomi benkonzo yevalve yemagnethi yeSMT.Thenga ukuba indala kangakanani icompressor yomoya ukuze ixhomekeke ekusetyenzisweni kwerhasi kunye nobude bomgca, kubhetele ukuba uthenge intwana enkulu, nokuba kamva wongeza ukuba sesiphi isixhobo onokuhlangabezana naso, umbhobho werhasi wobonelelo kufuneka ukhethe ubukhulu, kungcono ube li-12 ngaphezulu.I-AOI yibhamethrikhi.
Ngoko kushwankathelwa, umatshini wokubekwa kwiimfuno zokukhetha icompressor yomoya?
Ezona mfuno ziphambili zezi:
1. Umoya ocinezelweyo kufuneka wome ngokwaneleyo, kwaye i-compressor yomoya kufuneka ixhotyiswe ngesomisi esibandayo.
2.umoya ocinezelweyo eluthulini, ioli kunye nezinye iimagazini ukuba zibe zincinci kangangoko, ukufaka isihluzo.
I-3.uxinzelelo lomoya oxinyiweyo ukuhlangabezana neemfuno zoxinzelelo, kodwa kunye nokuzinza okwaneleyo, kunokusebenza ixesha elide ngokuqhubekayo, ukuxhotyiswa ngamatanki okugcina igesi, ngokubanzi kunye neeseti ezimbini ze-compressor yomoya ukuqinisekisa umsebenzi ongaphazamiseki.
