電磁振動上(shang)供料器的工作過程：

是(shi)由于(yu)(yu)電(dian)磁鐵(tie)的吸引和支承彈(dan)簧(huang)的反向(xiang)(xiang)復位作用(yong)(yong),使料槽(cao)產(chan)生高速(su)高頻(pin)(50---100次/秒),微(wei)幅(0.5---1mm)振(zhen)動(dong),使工(gong)件(jian)逐步(bu)(bu)向(xiang)(xiang)高處(chu)移動(dong).當I=0時,料槽(cao)在(zai)支承彈(dan)簧(huang)作用(yong)(yong)下(xia)向(xiang)(xiang)右上(shang)方復位,工(gong)件(jian)依靠它與軌道(dao)(dao)的磨擦而(er)(er)隨軌道(dao)(dao)向(xiang)(xiang)右上(shang)方運(yun)動(dong),并(bing)逐步(bu)(bu)被加(jia)速(su).當I>0時,料槽(cao)在(zai)電(dian)磁鐵(tie)的吸引下(xia)向(xiang)(xiang)左(zuo)下(xia)方運(yun)動(dong),工(gong)件(jian)由于(yu)(yu)慣性作用(yong)(yong)而(er)(er)脫(tuo)離軌道(dao)(dao),繼續向(xiang)(xiang)右上(shang)方運(yun)動(dong)(滑移或(huo)跳躍),再經過(guo)光(guang)(guang)纖放(fang)大器的光(guang)(guang)電(dian)轉換作用(yong)(yong),經集成線路模擬(ni)轉換至下(xia)一循環(huan),周而(er)(er)復始,工(gong)件(jian)在(zai)軌道(dao)(dao)上(shang)作由低到高的運(yun)動(dong)。
