精密振動盤動(dong)(dong)盤(pan)料(liao)斗(dou)下(xia)(xia)面(mian)有個脈(mo)沖電磁鐵(tie)，可以使料(liao)斗(dou)作垂直(zhi)方(fang)向(xiang)振(zhen)動(dong)(dong)，由(you)傾斜(xie)的彈簧(huang)片(pian)帶(dai)動(dong)(dong)料(liao)斗(dou)繞其(qi)垂直(zhi)軸做扭擺振(zhen)動(dong)(dong)。料(liao)斗(dou)內(nei)零件(jian)，由(you)于受到這種振(zhen)動(dong)(dong)而沿螺旋軌(gui)道(dao)(dao)上升(sheng)。在上升(sheng)的過程中經過一(yi)系(xi)列(lie)軌(gui)道(dao)(dao)的篩選或者姿態(tai)變化，零件(jian)能夠按照(zhao)組(zu)裝或者加工(gong)的要(yao)求呈統(tong)一(yi)狀態(tai)自動(dong)(dong)進(jin)入組(zu)裝或者加工(gong)位置(zhi)。 其(qi)工(gong)作目的是通過振(zhen)動(dong)(dong)將無序工(gong)件(jian)自動(dong)(dong)有序定向(xiang)排列(lie)整齊、準(zhun)確地輸送到下(xia)(xia)道(dao)(dao)工(gong)序。
