[0020] In order to better achieve the purpose of the present invention, the present invention also provides a testing method for an inductor automatic testing and sorting device, comprising the following steps:

[0021] Step 1: The first cylinder linear slide drives the transfer support plate to move, thereby driving the first fixed plate, the second fixed plate, the third fixed plate and the flip clamp blanking assembly on the transfer support plate to move, so that the L-shaped clamp is aligned with the magnetic ring inductor on the first conveyor, the first fixed U-shaped clamp and the second fixed U-shaped clamp are aligned with the magnetic ring inductor on the first support platform, the first side clamp block and the second side clamp block are aligned with the magnetic ring inductor on the second support platform, and the flip clamp blanking assembly is aligned with the magnetic ring inductor on the second test platform;
