[0028] like Figure 2 As shown, fixing plates 14 are fixedly installed at both ends of the bottom surface of the circuit board 13, and the fixing plates 14 are penetrated with through holes matched with the automatic screw driving machine 12. The screws are passed through the through holes on the fixing plates 14 by the automatic screw driving machine 12, so that the fixing plates 14 can be connected with the plastic plug plate 16, thereby making the circuit board 13 and the plastic plug plate 16 tightly connected after assembly.

[0029] like Figure 4 As shown, the upper end surface of the processing table 2 is located below the movable plate 6 and is rotatably connected to a guide plate 7. A lifting assembly is provided on the bottom surface of the guide plate 7. The lifting assembly is used to lift the end of the guide plate 7 to an inclined state.

At this time, the fixing plates 14 set at both ends of the bottom of the circuit board 13 are set outside the two ends of the plastic insert plate 16, and then the fixing plates 14 are connected. Then, the automatic screw driving machine 12 respectively arranged on the upper end surfaces of the correction rod 17 and the extrusion plate 19 can connect the fixed plate 14 with the plastic plug plate 16 through the through hole penetrated through the fixed plate 14 after sliding. Then, the user can rotate the movable plate 6 to make the other group of plastic plug plates 16 flip upward. On the one hand, the plastic plug plates 16 can be clamped and fixed by the correction rods 17 and the extrusion plates 19 arranged on the other group of movable plates 6, and then assembled with the circuit board 13. On the other hand, the movable plate 6 flipped downward can release the assembled plastic plug plates 16 and circuit board 13, and the released combination of circuit board 13 and plastic plug plates 16 slides downward along the inclined guide plate 7, so that the staff in front of the processing table 2 can perform performance testing on the assembled circuit board 13 and plastic plug plates 16.
