AI Technical Summary

⚠Technical Problem

Existing coil testing fixtures cannot test the charging performance of wireless charging coils at the finished product level.

⚗Method used

A coil testing fixture was designed, including a middle cover plate, a receiving module, and a transmitting module. The transmitting module is clamped by a main groove on the middle cover plate and a lower cover plate, and the receiving module is integrated to perform coupling tests at the coil module end, ensuring the charging performance test of the coil at the finished product end.

🎯Benefits of technology

This technology enables 100% coupling testing of the coil at the finished product end, ensuring the accuracy and reliability of the test results and avoiding errors caused by coil movement during the test.
