Abstract: A printed circuit board homogenization treatment device includes a load mechanism, a position mechanism and a drive mechanism. The load mechanism is disk-shaped and configured to fix the printed circuit board; the position mechanism at least includes a first position wheel and a second position wheel that can jointly support the load mechanism; the position mechanism is switchable between a first state and a second state; when the position mechanism is in the first state, the load mechanism and the drive mechanism are spaced apart; when the position mechanism is in the second state, the drive mechanism is configured to drive the load mechanism to rotate around its central axis; both the first position wheel and the second position wheel are configured to rotate with rotation of the load mechanism.

Abstract: Disclosed is a surface treatment device. The surface treatment device includes: a frame; a disc hanger; two support wheels for supporting the disk hanger; a rotation drive mechanism for driving the disk hanger supported on the two support wheels to rotate; a vertical spray rack for spraying liquid medicine on the circuit board on the disk hanger; and a lift mechanism for driving the vertical spray rack up and down.
