The driving mechanism 9 includes a reset motor 901 and a driving shaft 902, the reset motor 901 is installed on the rack 203, the driving shaft 902 is installed on the material receiving base 201 and penetrates through two sides of the material receiving base 201, the material receiving base 201 is supported and rotatably installed on the rack 203 through the driving shaft 902, the material receiving base 201 is connected with the reset motor 901 through the driving shaft 902, and the driving shaft 902 is parallel to the stop plate 2021 and the rotating roller 402.

The driving shaft 902 is positioned between two ends of the material receiving base 201, one side of the end of the material receiving base 201 is movably connected with the rack 203 through the horizontal calibration mechanism 13, and the horizontal calibration mechanism 13 is used for assisting the material receiving base 201 to accurately return to a horizontal state when the material receiving base 201 is reset to the horizontal state;

the horizontal calibration mechanism 13 includes a connecting rod 1301, a permanent magnet 1302 and an electromagnet 1303, one end of the connecting rod 1301 is installed on the side wall of the material receiving base 201, the other end of the connecting rod is installed with the permanent magnet 1302, the electromagnet 1303 is installed on the rack 203 and located on one side of the movement path of the material receiving base 201 and the permanent magnet 1302, and the permanent magnet 1302 is adsorbed by the electromagnet 1303 when the material receiving base 201 is in a horizontal state.

Specifically, when the reset motor 901 drives the material receiving base 201 to swing through the driving shaft 902, the connecting rod 1301 and the armature on the side of the material receiving base 201 rotate around the driving shaft 902. The reset motor 901 drives the material receiving base 201 to reset to a horizontal state and then power off is performed, so that the situation that the self-locking characteristic of the reset motor 901 affects the driving of the horizontal calibration mechanism 13 is prevented, and the material receiving base 201 cannot be accurately reset to the horizontal state due to factors such as errors of the reset motor 901 is avoided.

It is further optimized in the above embodiment that both sides of the material receiving base 201 are movably connected to the rack 203 through the horizontal calibration mechanisms 13, and the connecting rods 1301 at both sides of the material receiving base 201 are symmetrically arranged with respect to the central line of the material receiving base 201 to ensure that both sides of the material receiving base 201 are uniformly stressed, so that the horizontal calibration mechanisms 13 at both sides realize the function of stably supporting the horizontal material receiving base 201 when the reset motor 901 is powered off, and therefore, it is further optimized that the connecting rods 1301 are arranged at the tail end of the material receiving base 201 to enhance the supporting effect of the tail end of the material receiving base 201 where the stop plate 2021 is installed, and thus the material receiving base 201 is kept stable when the lower plate mechanism assembles the PCB circuit board on the housing to be assembled on the material receiving base 201.
