Printed circuit board (PCB) printing device

The invention discloses a PCB (printed circuit board) printing device, which belongs to the field of printing devices and comprises a rack, and a plug hole printing box, a first green oil printing box and a second green oil printing box are sequentially arranged on the top end surface of the rack from one side to the other side. The plug hole printing box, the first green oil printing box and the second green oil printing box are each internally provided with a double-layer staggered board feeding structure and a silk screen anti-deformation printing structure, and the double-layer staggered board feeding structures are used for sequentially feeding PCBs to the position below the silk screen anti-deformation printing structures in a staggered mode. The interiors of the hole plugging printing box, the first green oil printing box and the second green oil printing box are jointly connected with an overturning and transferring structure, the overturning and transferring structure is used for overturning the PCBs
