電磁(ci)振動(dong)上供料器(qi)的工作過程(cheng)：

是由于電磁鐵的吸(xi)引和(he)支承(cheng)(cheng)彈簧的反(fan)向復位作用(yong),使料(liao)槽(cao)(cao)產生高(gao)速高(gao)頻(pin)(50---100次(ci)/秒),微幅(0.5---1mm)振動(dong)(dong),使工(gong)(gong)件逐步向高(gao)處移動(dong)(dong).當I=0時(shi),料(liao)槽(cao)(cao)在(zai)(zai)支承(cheng)(cheng)彈簧作用(yong)下(xia)向右上方(fang)復位,工(gong)(gong)件依靠(kao)它與軌道(dao)(dao)的磨擦而(er)隨軌道(dao)(dao)向右上方(fang)運動(dong)(dong),并逐步被加速.當I>0時(shi),料(liao)槽(cao)(cao)在(zai)(zai)電磁鐵的吸(xi)引下(xia)向左下(xia)方(fang)運動(dong)(dong),工(gong)(gong)件由于慣性作用(yong)而(er)脫離軌道(dao)(dao),繼續向右上方(fang)運動(dong)(dong)(滑移或跳躍),再經(jing)過光纖放大器的光電轉(zhuan)換作用(yong),經(jing)集成(cheng)線路模擬轉(zhuan)換至下(xia)一循環,周而(er)復始,工(gong)(gong)件在(zai)(zai)軌道(dao)(dao)上作由低(di)到(dao)高(gao)的運動(dong)(dong)。
