精密振動盤動(dong)(dong)(dong)盤料(liao)斗(dou)(dou)下面有個脈沖電磁鐵，可以使(shi)料(liao)斗(dou)(dou)作垂(chui)直方向振動(dong)(dong)(dong)，由傾(qing)斜的(de)彈簧(huang)片帶(dai)動(dong)(dong)(dong)料(liao)斗(dou)(dou)繞其垂(chui)直軸(zhou)做扭(niu)擺振動(dong)(dong)(dong)。料(liao)斗(dou)(dou)內零件，由于(yu)受到這種振動(dong)(dong)(dong)而沿螺旋軌(gui)道(dao)上(shang)升(sheng)。在上(shang)升(sheng)的(de)過程(cheng)中(zhong)經過一(yi)(yi)系(xi)列(lie)軌(gui)道(dao)的(de)篩選或者(zhe)姿態變化，零件能夠按照組裝或者(zhe)加工(gong)(gong)的(de)要求呈(cheng)統一(yi)(yi)狀(zhuang)態自動(dong)(dong)(dong)進入(ru)組裝或者(zhe)加工(gong)(gong)位(wei)置(zhi)。 其工(gong)(gong)作目的(de)是(shi)通(tong)過振動(dong)(dong)(dong)將無(wu)序(xu)工(gong)(gong)件自動(dong)(dong)(dong)有序(xu)定向排列(lie)整齊、準(zhun)確地輸送(song)到下道(dao)工(gong)(gong)序(xu)。
