電磁(ci)振動上供料器(qi)的工作過程：

是(shi)由(you)于電磁鐵的(de)(de)(de)(de)吸引和支承彈簧的(de)(de)(de)(de)反向(xiang)復位(wei)作用(yong)(yong),使(shi)(shi)料(liao)(liao)槽產(chan)生高速高頻(50---100次/秒),微幅(fu)(0.5---1mm)振動(dong),使(shi)(shi)工(gong)(gong)件(jian)逐步向(xiang)高處(chu)移動(dong).當I=0時,料(liao)(liao)槽在支承彈簧作用(yong)(yong)下向(xiang)右上(shang)方(fang)復位(wei),工(gong)(gong)件(jian)依靠它與軌(gui)(gui)道(dao)的(de)(de)(de)(de)磨擦而隨軌(gui)(gui)道(dao)向(xiang)右上(shang)方(fang)運動(dong),并逐步被加速.當I>0時,料(liao)(liao)槽在電磁鐵的(de)(de)(de)(de)吸引下向(xiang)左下方(fang)運動(dong),工(gong)(gong)件(jian)由(you)于慣性作用(yong)(yong)而脫離軌(gui)(gui)道(dao),繼續向(xiang)右上(shang)方(fang)運動(dong)(滑移或跳躍),再經過光(guang)纖(xian)放(fang)大器的(de)(de)(de)(de)光(guang)電轉換作用(yong)(yong),經集成(cheng)線(xian)路模擬轉換至(zhi)下一(yi)循環(huan),周(zhou)而復始,工(gong)(gong)件(jian)在軌(gui)(gui)道(dao)上(shang)作由(you)低(di)到(dao)高的(de)(de)(de)(de)運動(dong)。
