[0002] In the electronics manufacturing industry, the selection of electronic leads is an indispensable part of the production process. However, traditional methods for selecting electronic leads mainly rely on manual observation and operation.

[0003] However, when faced with a large number of electronic lead screening tasks, this screening method can easily lead to worker fatigue due to long working hours, which affects the screening speed. Since the speed of manual screening is limited, the screening process takes a long time when faced with a large number of electronic leads, which affects the subsequent processing and use of the electronic leads.

[0004] Therefore, in order to solve the problem of time-consuming manual screening of electronic leads, this utility model proposes a novel multi-stage screening mechanism design for electronic leads. Utility Model Content
