電磁(ci)振動上供料器(qi)的(de)工(gong)作過程：

是由于電(dian)磁鐵(tie)的(de)(de)吸(xi)引(yin)和支承(cheng)彈簧的(de)(de)反向(xiang)(xiang)(xiang)復位(wei)(wei)作(zuo)用(yong)(yong)(yong),使(shi)料槽(cao)(cao)產生高(gao)速高(gao)頻(50---100次/秒),微幅(0.5---1mm)振動(dong)(dong),使(shi)工(gong)(gong)件(jian)逐步向(xiang)(xiang)(xiang)高(gao)處移動(dong)(dong).當(dang)I=0時(shi),料槽(cao)(cao)在支承(cheng)彈簧作(zuo)用(yong)(yong)(yong)下(xia)向(xiang)(xiang)(xiang)右上(shang)方(fang)復位(wei)(wei),工(gong)(gong)件(jian)依靠它與軌(gui)道的(de)(de)磨擦而隨軌(gui)道向(xiang)(xiang)(xiang)右上(shang)方(fang)運(yun)動(dong)(dong),并逐步被加(jia)速.當(dang)I>0時(shi),料槽(cao)(cao)在電(dian)磁鐵(tie)的(de)(de)吸(xi)引(yin)下(xia)向(xiang)(xiang)(xiang)左下(xia)方(fang)運(yun)動(dong)(dong),工(gong)(gong)件(jian)由于慣性作(zuo)用(yong)(yong)(yong)而脫離軌(gui)道,繼續(xu)向(xiang)(xiang)(xiang)右上(shang)方(fang)運(yun)動(dong)(dong)(滑移或跳躍),再(zai)經過(guo)光(guang)纖放大(da)器的(de)(de)光(guang)電(dian)轉換(huan)(huan)作(zuo)用(yong)(yong)(yong),經集成線路模擬轉換(huan)(huan)至下(xia)一循(xun)環,周而復始,工(gong)(gong)件(jian)在軌(gui)道上(shang)作(zuo)由低到高(gao)的(de)(de)運(yun)動(dong)(dong)。
