SMT貼片(pian)機送(song)料器(qi)(qi)也(ye)叫作(zuo)供料器(qi)(qi),通(tong)常也(ye)稱為:喂料器(qi)(qi),給料器(qi)(qi),料槍,FEEDER,飛達,下面為大講解下smt貼片(pian)機送(song)料器(qi)(qi)的分類。

1.帶(dai)式(shi)(shi)送(song)料(liao)(liao)器:是(shi)貼片機送(song)料(liao)(liao)器中常用的種標(biao)準送(song)料(liao)(liao)器,傳統(tong)結(jie)構(gou)方式(shi)(shi)有輪式(shi)(shi)、爪(zhua)式(shi)(shi)、氣動(dong)式(shi)(shi)以及多間距電(dian)動(dong)式(shi)(shi),現在(zai)已經發展(zhan)為(wei)高精度(du)電(dian)動(dong)式(shi)(shi),高精度(du)電(dian)動(dong)式(shi)(shi)與傳統(tong)結(jie)構(gou)方式(shi)(shi)相對,傳送(song)精度(du)更(geng)(geng)高、送(song)料(liao)(liao)速度(du)更(geng)(geng)快、結(jie)構(gou)更(geng)(geng)加緊湊(cou),性能更(geng)(geng)穩定,大大提高了生產效率。

帶狀料的基(ji)本寬度有(you):8mm、12mm、16mm、24mm、32mm、44mm和(he)(he)52mm等多種類型(xing),間(jian)距有(you)2mm、4mm、8mm、12mm和(he)(he)16等;卷軸直徑尺寸有(you)7 in和(he)(he)13 in兩種。

2.托(tuo)(tuo)盤(pan)(pan)(pan)式(shi)送料(liao)(liao)器(qi),盤(pan)(pan)(pan)式(shi)送料(liao)(liao)器(qi):可以(yi)分為(wei)單層結構和多層結構,單層托(tuo)(tuo)盤(pan)(pan)(pan)式(shi)送料(liao)(liao)器(qi)是直接安(an)裝在貼片機送料(liao)(liao)器(qi)架上,占(zhan)用(yong)多個(ge)糟(zao)位,適(shi)用(yong)于托(tuo)(tuo)盤(pan)(pan)(pan)式(shi)料(liao)(liao)不多的情(qing)況;多層托(tuo)(tuo)盤(pan)(pan)(pan)式(shi)送器(qi)料(liao)(liao)有多層自(zi)動(dong)傳送托(tuo)(tuo)盤(pan)(pan)(pan),占(zhan)用(yong)空間小,結構緊湊,適(shi)用(yong)于托(tuo)(tuo)盤(pan)(pan)(pan)料(liao)(liao)比較多的的情(qing)況,盤(pan)(pan)(pan)裝元器(qi)件多為(wei)各種IC集成電路元件。

在(zai)使(shi)用托(tuo)盤(pan)式料時,需要(yao)注意保住(zhu)大管角(jiao)外露(lu)元(yuan)器(qi)件,以(yi)防止(zhi)在(zai)運輸和使(shi)用中造成機械和電性能的損壞。在(zai)托(tuo)盤(pan)中使(shi)用TQFP、PQFP、BGA、TSOP和SSOPs元(yuan)器(qi)件時,托(tuo)盤(pan)尺寸可以(yi)達到150mm x 330.2mm,高度25.4mm。有趣的是,托(tuo)盤(pan)式送料器(qi)不僅(jin)可以(yi)供給貼片機拾取元(yuan)器(qi)件,也可以(yi)做為貴(gui)重元(yuan)器(qi)件的勢拋料站。

3.管(guan)式送(song)料(liao)器(qi):通常使(shi)用振動(dong)送(song)料(liao)器(qi)來保證管(guan)中(zhong)元器(qi)件不斷進入(ru)貼片頭吸取位置,般PLCC和SOIC是用這種方式來供料(liao)的。管(guan)式供料(liao)器(qi)有對元器(qi)件引腳保護作用好,穩定性和規范性較(jiao)差,生產效率(lv)較(jiao)底的特點。

4. 散料(liao)盒(he)式(shi)(shi)送(song)(song)(song)料(liao)器(qi)(振(zhen)動(dong)飛(fei)達):又稱為(wei)振(zhen)動(dong)式(shi)(shi)送(song)(song)(song)器(qi)料(liao),其工(gong)作(zuo)方式(shi)(shi)是(shi)將(jiang)元(yuan)(yuan)器(qi)件自由(you)地(di)裝(zhuang)入成型(xing)的(de)塑料(liao)盒(he)或袋內,通(tong)過用振(zhen)動(dong)式(shi)(shi)送(song)(song)(song)料(liao)器(qi)或送(song)(song)(song)料(liao)管(guan)把元(yuan)(yuan)器(qi)件依(yi)次(ci)送(song)(song)(song)入貼(tie)片機,這(zhe)種(zhong)方式(shi)(shi)通(tong)常使用于(yu)MELF和小外形半導件元(yuan)(yuan)器(qi)件,只適(shi)用于(yu)性(xing)(xing)矩形和柱形元(yuan)(yuan)器(qi)件,而不適(shi)用于(yu)性(xing)(xing)元(yuan)(yuan)器(qi)件。特點:振(zhen)動(dong)飛(fei)達比較(jiao)貴。

5.振(zhen)動(dong)盤 Vibration Feeder 特殊飛達(da),需(xu)定制。
