貼(tie)片機(ji)是用(yong)于(yu)電子行業所(suo)使用(yong)的設備,主要可用(yong)于(yu)各種(zhong)產品的貼(tie)裝(zhuang)。相比于(yu)人工來(lai)說(shuo),使用(yong)貼(tie)片機(ji)進行貼(tie)裝(zhuang),效(xiao)率以及質量方面都有所(suo)提高。但是設備的完成一般都是由不(bu)同的結構組(zu)合而成的,貼(tie)片機(ji)也不(bu)例(li)外,那么貼(tie)片機(ji)的具體結構是什(shen)么?
貼片機的具體結構
1、機(ji)(ji)(ji)架:在貼片(pian)機(ji)(ji)(ji)的(de)結構中,機(ji)(ji)(ji)架是(shi)(shi)機(ji)(ji)(ji)器(qi)的(de)基礎,所有(you)的(de)傳動、定位(wei)、傳送機(ji)(ji)(ji)構均(jun)牢固地(di)固定在它上面。目前各種(zhong)(zhong)(zhong)形式的(de)機(ji)(ji)(ji)架可(ke)以分(fen)為整體鑄造式、鋼板燒焊(han)式兩(liang)種(zhong)(zhong)(zhong),但是(shi)(shi)由于大部(bu)分(fen)型號的(de)貼片(pian)機(ji)(ji)(ji)及其各種(zhong)(zhong)(zhong)送料器(qi)也(ye)安置在上面,因此機(ji)(ji)(ji)架應有(you)足(zu)夠(gou)的(de)機(ji)(ji)(ji)械(xie)強度和剛性。
2、傳(chuan)送(song)(song)(song)機構與支撐臺(tai):傳(chuan)送(song)(song)(song)機構是指安放在軌道上的(de)超薄型(xing)皮帶(dai)傳(chuan)送(song)(song)(song)系(xi)統(tong),所(suo)起到的(de)主要(yao)作(zuo)用是將需(xu)要(yao)貼片的(de)PCB送(song)(song)(song)到預(yu)定位(wei)置,貼片完(wan)成后再將SMA送(song)(song)(song)下道工序。
3、X,Y定位系(xi)統(tong)(tong):X,Y定位系(xi)統(tong)(tong)不僅是貼片(pian)機的關(guan)鍵機構(gou),也是評(ping)估貼片(pian)機精度的主要(yao)指標,它包括X,Y傳動結構(gou)和X,Y伺服系(xi)統(tong)(tong)。
4、光學對中(zhong)系統:貼(tie)(tie)片(pian)機的對中(zhong)是指貼(tie)(tie)片(pian)機在(zai)吸(xi)(xi)取元件時要保(bao)證吸(xi)(xi)嘴(zui)吸(xi)(xi)在(zai)元件中(zhong)心,使元件的中(zhong)心與貼(tie)(tie)片(pian)頭主軸的中(zhong)心線保(bao)持致。
5、貼(tie)片頭(tou):貼(tie)片頭(tou)是貼(tie)片機的關鍵(jian)部件(jian),它拾取元(yuan)件(jian)后能在(zai)校(xiao)正系(xi)統的控制下(xia)自動(dong)校(xiao)正位置,并(bing)將元(yuan)器件(jian)準(zhun)確地(di)貼(tie)放到(dao)指(zhi)定的位置。
6、供料器(qi):在貼(tie)片機中供料器(qi)占有教(jiao)多的數量和位置,作(zuo)用(yong)是將片式元器(qi)件SMC/SMD按照定(ding)規律和順序提供給貼(tie)片頭以便準確(que)方(fang)便地(di)拾取。
7、傳(chuan)(chuan)感器(qi)(qi):目前在貼(tie)(tie)片(pian)(pian)機(ji)中都有(you)(you)裝有(you)(you)多(duo)種傳(chuan)(chuan)感器(qi)(qi),可進行元件電器(qi)(qi)性能檢(jian)查,它們象貼(tie)(tie)片(pian)(pian)機(ji)的(de)眼(yan)睛(jing)樣(yang),時(shi)刻監(jian)視機(ji)器(qi)(qi)的(de)正常運轉。常見(jian)的(de)主要有(you)(you)壓力傳(chuan)(chuan)感器(qi)(qi)、負壓傳(chuan)(chuan)感器(qi)(qi)和位置傳(chuan)(chuan)感器(qi)(qi)等,般來說,傳(chuan)(chuan)感器(qi)(qi)運用(yong)越多(duo),表示(shi)貼(tie)(tie)片(pian)(pian)機(ji)的(de)智能化水平(ping)越高。
貼片(pian)機的結構(gou)主(zhu)要(yao)是機架(jia)、傳送機構(gou)與支撐臺、X,Y定位系(xi)統(tong)、光學對中系(xi)統(tong)、貼片(pian)頭(tou)、供料器及傳感器等七(qi)大(da)結構(gou)組合而成(cheng)。
