電磁振(zhen)動上供料器的工(gong)作過(guo)程：

是(shi)由于(yu)電磁鐵的(de)(de)吸(xi)引(yin)和支承彈簧的(de)(de)反向復位(wei)作(zuo)用(yong)(yong),使料槽(cao)產生高(gao)(gao)(gao)速高(gao)(gao)(gao)頻(50---100次/秒),微幅(0.5---1mm)振動(dong)(dong)(dong),使工件(jian)逐步(bu)向高(gao)(gao)(gao)處移動(dong)(dong)(dong).當(dang)I=0時,料槽(cao)在支承彈簧作(zuo)用(yong)(yong)下(xia)向右(you)上(shang)方(fang)復位(wei),工件(jian)依(yi)靠它與軌道(dao)的(de)(de)磨(mo)擦(ca)而隨軌道(dao)向右(you)上(shang)方(fang)運(yun)動(dong)(dong)(dong),并逐步(bu)被加速.當(dang)I>0時,料槽(cao)在電磁鐵的(de)(de)吸(xi)引(yin)下(xia)向左下(xia)方(fang)運(yun)動(dong)(dong)(dong),工件(jian)由于(yu)慣(guan)性作(zuo)用(yong)(yong)而脫離軌道(dao),繼續向右(you)上(shang)方(fang)運(yun)動(dong)(dong)(dong)(滑移或跳(tiao)躍(yue)),再經過光(guang)纖放(fang)大器的(de)(de)光(guang)電轉換(huan)作(zuo)用(yong)(yong),經集成線路(lu)模擬轉換(huan)至下(xia)一循環,周而復始,工件(jian)在軌道(dao)上(shang)作(zuo)由低到高(gao)(gao)(gao)的(de)(de)運(yun)動(dong)(dong)(dong)。
