求各位高手幫忙？我們廠(chǎng)里有臺非標的機械手，Y軸上裝有一個(gè)防撞報警的 超聲波接近開(kāi)關(guān)，PNP，常閉的。最近機械手運行時(shí)，該接近開(kāi)關(guān)的信號老是瞬間斷掉，然后停機報警。換了一個(gè)接近開(kāi)關(guān)也是一樣的故障，仔細觀(guān)察發(fā)現，X軸的直線(xiàn)導軌磨損厲害，小弟有個(gè)疑問(wèn)，接近開(kāi)關(guān)的信號會(huì )突然斷掉，是接近開(kāi)關(guān)的原因，還是機械手運行的時(shí)候震動(dòng)太大導致的呢？超聲波接近開(kāi)關(guān)有那么大的精度嗎？

傳感器的線(xiàn)經(jīng)過(guò)長(cháng)時(shí)往復運動(dòng)快斷了接觸不良
自動(dòng)化單機，生產(chǎn)線(xiàn)，項目編程調試！
