摘 要：雙線圈磁保持繼電器的吸合電壓和復(fù)歸電壓均需分級(jí)再進(jìn)行組合，且組合數(shù)最多達(dá) 16 種。針對(duì)傳統(tǒng)手工篩選方式存在效率低和差錯(cuò)率高等局限性，開(kāi)發(fā)了一種磁保持繼電器自動(dòng)檢測(cè)系統(tǒng)，介紹系統(tǒng)各組成單元及相應(yīng)功能，并給出相應(yīng)環(huán)節(jié)注意事項(xiàng)，經(jīng)測(cè)試準(zhǔn)確性與測(cè)試效率比較，該系統(tǒng)實(shí)現(xiàn)了取料、測(cè)試與分級(jí)、噴碼、收料四個(gè)過(guò)程高效緊密銜接，減少周轉(zhuǎn)，不僅提高測(cè)試效率，還能確保測(cè)試分級(jí)準(zhǔn)確性，避免因混入分級(jí)錯(cuò)誤產(chǎn)品帶來(lái)的質(zhì)量風(fēng)險(xiǎn)。
關(guān)鍵詞：雙線圈磁保持繼電器；測(cè)試分級(jí)；吸合電壓；復(fù)歸電壓

Abstract: The pull-in voltage and reset voltage of the double coil magnetic latching relay need to be combined by stages, and there are 16 ways of combination.There are existing limitations of traditional manual screening methods, such as low efficiency and high error rate. This paper develops an automatic detection system for magnetic latching relays. It introduces the constituent units and corresponding functions of the system and gives precautions to the particular parts. After comparing the accuracy and efficiency of the tests, the system has achieved a profound effort. The processes of reclaiming, testing and grading, coding, and receiving have well engagement. This system improves test efficiency and ensures the accuracy of the test. Furthermore, it avoids the quality risk caused by mixing products with the wrong classification.
Key words: double coil magnetic latching relay; test classification; pull-in voltage; reset voltage
