精密振動盤動(dong)(dong)(dong)盤料斗下(xia)面有個脈沖電磁鐵，可以使料斗作垂直方向(xiang)振(zhen)動(dong)(dong)(dong)，由傾(qing)斜的(de)彈簧片(pian)帶動(dong)(dong)(dong)料斗繞其(qi)垂直軸做扭擺振(zhen)動(dong)(dong)(dong)。料斗內零件，由于受到(dao)這種振(zhen)動(dong)(dong)(dong)而(er)沿螺(luo)旋(xuan)軌道(dao)上升。在上升的(de)過程中經過一(yi)系列(lie)軌道(dao)的(de)篩選(xuan)或者姿態變化，零件能夠(gou)按照組裝(zhuang)或者加工(gong)(gong)的(de)要求(qiu)呈統一(yi)狀(zhuang)態自動(dong)(dong)(dong)進入組裝(zhuang)或者加工(gong)(gong)位置。 其(qi)工(gong)(gong)作目的(de)是通過振(zhen)動(dong)(dong)(dong)將無序(xu)(xu)工(gong)(gong)件自動(dong)(dong)(dong)有序(xu)(xu)定向(xiang)排列(lie)整齊、準(zhun)確地輸送到(dao)下(xia)道(dao)工(gong)(gong)序(xu)(xu)。
