摘 要：為滿足標準要求，在用的小型繼電器需要篩選分類后才能使用，而傳統手工篩選方式存在效率低和差錯率高等局限性。開發了一種小型單線圈繼電器測試分選系統，該系統集上料單元、測試分級單元、噴碼單元、收料單元和安全防護單元于一體，巧妙地將取料、測試與分級、噴碼、裝盒四個過程高效銜接起來，經測試準確性與測試效率對比，大為減少中間周轉時間，不僅提高了測試效率，而且還能保證分級準確性，避免越級產品混入生產流程帶來的質量風險。
關鍵詞：單線圈繼電器；分類；噴碼；效率；準確性

Abstract: In order to meet the standard requirements, the small relay in use needs to be screened and classified before it can be used, however, the traditional manual screening method has the limitations of low efficiency and high error rate.This paper developed a small single coil relay testing and sorting system, which integrated feeding unit, test grading unit, spray printing unit, receiving unit and safety protection unit, and skillfully connected the four processes of feeding, testing and classification, spray printing and packing, greatly reduced the intermediate turnaround time.After comparison of testing accuracy and efficiency, it is found that this system not only improves the test efficiency, but also ensures the accuracy of classification to avoid the quality risk caused by cross-grade products mixed into the production process.
Key words: single coil relay; classification; spray printing; efficiency; accuracy
