電磁振(zhen)動上供料器的(de)工作過程：

是由于電磁鐵(tie)的吸(xi)(xi)引(yin)和支(zhi)(zhi)承彈簧(huang)的反向(xiang)(xiang)復位作用,使料槽(cao)(cao)(cao)產生高(gao)速高(gao)頻(50---100次/秒),微幅(0.5---1mm)振動(dong)(dong)(dong)(dong),使工件逐(zhu)步向(xiang)(xiang)高(gao)處移動(dong)(dong)(dong)(dong).當(dang)I=0時,料槽(cao)(cao)(cao)在(zai)支(zhi)(zhi)承彈簧(huang)作用下向(xiang)(xiang)右上(shang)(shang)方復位,工件依靠它與軌(gui)道(dao)的磨(mo)擦而隨軌(gui)道(dao)向(xiang)(xiang)右上(shang)(shang)方運(yun)(yun)動(dong)(dong)(dong)(dong),并(bing)逐(zhu)步被加速.當(dang)I>0時,料槽(cao)(cao)(cao)在(zai)電磁鐵(tie)的吸(xi)(xi)引(yin)下向(xiang)(xiang)左下方運(yun)(yun)動(dong)(dong)(dong)(dong),工件由于慣(guan)性作用而脫離(li)軌(gui)道(dao),繼續向(xiang)(xiang)右上(shang)(shang)方運(yun)(yun)動(dong)(dong)(dong)(dong)(滑移或(huo)跳躍),再(zai)經(jing)過光纖放大(da)器的光電轉(zhuan)換作用,經(jing)集成線路模擬(ni)轉(zhuan)換至下一循環,周(zhou)而復始,工件在(zai)軌(gui)道(dao)上(shang)(shang)作由低到(dao)高(gao)的運(yun)(yun)動(dong)(dong)(dong)(dong)。
