電磁振動(dong)上供(gong)料器的(de)工作過程：

是(shi)由于電(dian)磁鐵的(de)吸引(yin)和支(zhi)承(cheng)彈(dan)簧的(de)反向(xiang)復位(wei)作用(yong)(yong),使(shi)(shi)料槽產生高速(su)高頻(50---100次(ci)/秒),微幅(0.5---1mm)振動(dong)(dong),使(shi)(shi)工(gong)(gong)件逐(zhu)(zhu)步(bu)向(xiang)高處移動(dong)(dong).當I=0時(shi)(shi),料槽在支(zhi)承(cheng)彈(dan)簧作用(yong)(yong)下(xia)(xia)向(xiang)右上方復位(wei),工(gong)(gong)件依靠(kao)它(ta)與軌道(dao)的(de)磨擦而隨軌道(dao)向(xiang)右上方運動(dong)(dong),并(bing)逐(zhu)(zhu)步(bu)被(bei)加速(su).當I>0時(shi)(shi),料槽在電(dian)磁鐵的(de)吸引(yin)下(xia)(xia)向(xiang)左下(xia)(xia)方運動(dong)(dong),工(gong)(gong)件由于慣性作用(yong)(yong)而脫(tuo)離軌道(dao),繼續向(xiang)右上方運動(dong)(dong)(滑移或跳(tiao)躍),再經(jing)過光纖放大器的(de)光電(dian)轉(zhuan)換(huan)作用(yong)(yong),經(jing)集成線路(lu)模擬轉(zhuan)換(huan)至下(xia)(xia)一循(xun)環,周(zhou)而復始,工(gong)(gong)件在軌道(dao)上作由低到高的(de)運動(dong)(dong)。
