電磁振動上供料器的(de)工作(zuo)過程：

是由(you)于(yu)電磁鐵(tie)的吸引和(he)支承彈簧(huang)的反向(xiang)復(fu)(fu)位(wei)作用(yong)(yong),使料槽(cao)產生高(gao)(gao)(gao)速高(gao)(gao)(gao)頻(50---100次(ci)/秒(miao)),微幅(fu)(0.5---1mm)振(zhen)動(dong),使工(gong)(gong)件(jian)逐(zhu)步向(xiang)高(gao)(gao)(gao)處移動(dong).當(dang)I=0時,料槽(cao)在(zai)支承彈簧(huang)作用(yong)(yong)下(xia)(xia)向(xiang)右(you)(you)上方(fang)復(fu)(fu)位(wei),工(gong)(gong)件(jian)依靠(kao)它與軌(gui)道(dao)的磨擦(ca)而隨軌(gui)道(dao)向(xiang)右(you)(you)上方(fang)運動(dong),并逐(zhu)步被加速.當(dang)I>0時,料槽(cao)在(zai)電磁鐵(tie)的吸引下(xia)(xia)向(xiang)左(zuo)下(xia)(xia)方(fang)運動(dong),工(gong)(gong)件(jian)由(you)于(yu)慣性作用(yong)(yong)而脫離(li)軌(gui)道(dao),繼續向(xiang)右(you)(you)上方(fang)運動(dong)(滑移或跳躍),再經(jing)(jing)過光纖放大器的光電轉(zhuan)換作用(yong)(yong),經(jing)(jing)集(ji)成(cheng)線路模(mo)擬轉(zhuan)換至下(xia)(xia)一循(xun)環,周而復(fu)(fu)始,工(gong)(gong)件(jian)在(zai)軌(gui)道(dao)上作由(you)低到高(gao)(gao)(gao)的運動(dong)。
