電磁(ci)振動上供料(liao)器的(de)工作過程：

是(shi)由(you)(you)于電磁鐵的(de)(de)吸引和支(zhi)承(cheng)彈(dan)簧(huang)的(de)(de)反向(xiang)(xiang)復位作(zuo)用(yong)(yong),使(shi)料(liao)槽產生(sheng)高速(su)高頻(50---100次/秒),微幅(0.5---1mm)振動,使(shi)工(gong)件(jian)逐(zhu)步(bu)(bu)向(xiang)(xiang)高處移(yi)動.當I=0時,料(liao)槽在支(zhi)承(cheng)彈(dan)簧(huang)作(zuo)用(yong)(yong)下向(xiang)(xiang)右(you)上(shang)方復位,工(gong)件(jian)依靠它與軌道(dao)(dao)的(de)(de)磨擦而隨軌道(dao)(dao)向(xiang)(xiang)右(you)上(shang)方運(yun)動,并逐(zhu)步(bu)(bu)被加速(su).當I>0時,料(liao)槽在電磁鐵的(de)(de)吸引下向(xiang)(xiang)左下方運(yun)動,工(gong)件(jian)由(you)(you)于慣(guan)性作(zuo)用(yong)(yong)而脫(tuo)離(li)軌道(dao)(dao),繼續向(xiang)(xiang)右(you)上(shang)方運(yun)動(滑移(yi)或(huo)跳躍),再經(jing)過光纖放大器的(de)(de)光電轉(zhuan)(zhuan)換(huan)作(zuo)用(yong)(yong),經(jing)集成(cheng)線路模擬轉(zhuan)(zhuan)換(huan)至下一循環,周而復始(shi),工(gong)件(jian)在軌道(dao)(dao)上(shang)作(zuo)由(you)(you)低到高的(de)(de)運(yun)動。
