摘 要：雙線圈磁保持繼電器的吸合電壓和復歸電壓均需分級再進行組合，且組合數最多達 16 種。針對傳統手工篩選方式存在效率低和差錯率高等局限性，開發了一種磁保持繼電器自動檢測系統，介紹系統各組成單元及相應功能，并給出相應環節注意事項，經測試準確性與測試效率比較，該系統實現了取料、測試與分級、噴碼、收料四個過程高效緊密銜接，減少周轉，不僅提高測試效率，還能確保測試分級準確性，避免因混入分級錯誤產品帶來的質量風險。
關鍵詞：雙線圈磁保持繼電器；測試分級；吸合電壓；復歸電壓

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
