精密振動盤動(dong)盤料斗下面有個脈沖電磁鐵，可(ke)以使(shi)料斗作垂(chui)直(zhi)方向(xiang)(xiang)振(zhen)動(dong)，由(you)傾(qing)斜的(de)彈簧片帶動(dong)料斗繞其垂(chui)直(zhi)軸做(zuo)扭擺振(zhen)動(dong)。料斗內零件(jian)(jian)，由(you)于受到(dao)(dao)這(zhe)種振(zhen)動(dong)而沿螺旋軌(gui)道上(shang)升。在上(shang)升的(de)過程(cheng)中經(jing)過一系列(lie)軌(gui)道的(de)篩選(xuan)或(huo)者姿態變(bian)化，零件(jian)(jian)能(neng)夠按照組(zu)裝或(huo)者加工(gong)(gong)(gong)的(de)要求呈統一狀態自(zi)動(dong)進入組(zu)裝或(huo)者加工(gong)(gong)(gong)位置(zhi)。 其工(gong)(gong)(gong)作目的(de)是通過振(zhen)動(dong)將無序工(gong)(gong)(gong)件(jian)(jian)自(zi)動(dong)有序定向(xiang)(xiang)排列(lie)整齊(qi)、準確地輸送到(dao)(dao)下道工(gong)(gong)(gong)序。
