AI Technical Summary
Traditional automated testing machines struggle to effectively test leaded miniature fuses, resulting in bent or defective leads, increased labor costs, and reduced production efficiency.
Design a pneumatic tester for multiple leads-based miniature fuses, comprising a fuse placement mechanism, a detection mechanism, and a drive mechanism. It uses test pins and indicator lights to perform simultaneous continuity and disconnection tests on multiple fuses, and employs a switching transistor control circuit to reduce costs.
It enables efficient continuity testing of multiple leaded miniature fuses, avoiding lead bending defects, reducing labor costs and improving production efficiency.

Abstract
Claims
1. A pneumatic tester for multi-channel continuity and disconnection of a miniature fuse with leads, characterized in that, include: A fuse placement mechanism has a plurality of fuse placement slots arranged sequentially, each of which is used to place a miniature fuse with a lead wire; The testing organization includes: The detection system is used to detect the continuity of a leaded miniature fuse. It has a first prompting unit, a second prompting unit, and multiple sets of test pins. The first prompting unit, the second prompting unit, and the multiple sets of test pins are arranged in a one-to-one correspondence with the fuse placement slot. Each set of test pins includes two test pins spaced apart. The two test pins are respectively used to insert into the fuse placement slot and abut against the two leads of a leaded miniature fuse. A driving mechanism is connected to the test pin drive, which is used to drive the test pin to move and abut against the leads on both sides of the leaded miniature fuse during testing, and to drive the test pin to move away from the leaded miniature fuse after testing is completed.
