The specific structure of the good board clip clamping and lifting mechanism 10 can refer to the clip clamping and lifting mechanism 5 to be tested, and the two structures are the same.

The conveying directions of the good board empty spring clamp conveying mechanism 20 and the good board receiving mechanism 30 are transverse, and the good board empty spring clamp conveying mechanism 20 and the good board receiving mechanism 30 are vertically arranged in parallel, and the discharging end of the good board empty spring clamp conveying mechanism 20 and the feeding end of the good board receiving mechanism 30 are positioned on the same side and are adjacent to the good board spring clamp clamping lifting mechanism 10.

The two side rails 31 are arranged in parallel and opposite. Two transmission assemblies 32 are respectively provided on the two side rails 31 for conveying the circuit board. The track push plate assembly 33 includes a limit post 331, a slider 332, a rotational block 333, a tension spring 334, and a push plate driver 335.

The rotating block 333 is rotatably connected with the sliding block 332, and the extension spring 334 connects the sliding block 332 and the rotating block 333, and the extension spring 334 is used for providing elastic force to enable the rotating block 333 to rotate upwards.

The push plate driver 335 is coupled to the slider 332 for driving the slider 332 longitudinally between a first position and a second position. When the sliding block 332 is located at the first position, the rotating block 333 is located below the limiting post 331, and when the sliding block 332 is located at the second position, the rotating block 333 is separated from the limiting post 331.

When the circuit board is about to completely leave the two transmission assemblies 32, the push plate driving member 335 drives the rotating block 333 to move, and the rotating block 333 is rotated upwards by the extension spring 334, so that the rotating block 333 contacts with the end surface of the circuit board, thereby pushing the circuit board. During the process of conveying the circuit board, the two transmission assemblies 32 cannot push the circuit board into the clip 8 completely because the two transmission assemblies 32 do not completely enter the clip 8 when the tail end of the circuit board leaves the two transmission assemblies 32, and the circuit board can be pushed into the clip 8 completely through the track push plate assembly 33.

The front discharging rail conveying mechanism 3 further comprises an inductor which is arranged at the discharging end of the front discharging rail conveying mechanism 3 and is used for inducing the circuit board, and when the inductor cannot induce the circuit board, the rotating block 333 extends out of the bottom of the limiting column 331 to push the circuit board.
