1. A printed circuit board homogenization treatment device for processing a printed circuit board, comprising: a load mechanism, a position mechanism and a drive mechanism, wherein:
the load mechanism is disk-shaped and configured to fix the printed circuit board, and a central axis of the load mechanism extends in a horizontal direction to vertically arrange the printed circuit board;
the position mechanism comprises at least a first position wheel and a second position wheel;
a rotation axis of the first position wheel and a rotation axis of the second position wheel both extend in a horizontal direction and are parallel to each other;
the load mechanism is supported by the first position wheel and the second position wheel;
the position mechanism is switchable between a first state and a second state;
when the position mechanism is in the first state and the load mechanism is placed on the first position wheel and the second position wheel, the load mechanism and the drive mechanism are spaced apart;
when the position mechanism is in the second state and the load mechanism is placed on the first position wheel and the second position wheel, the drive mechanism is configured to drive the load mechanism to rotate around the central axis of the load mechanism;
both the first position wheel and the second position wheel are configured to rotate with rotation of the load mechanism.
