Patent ID: 8061959

Claim:
A board inverter for inverting a board on a conveyor, the conveyor having a supporting surface, the board having a first surface facing toward the supporting surface and an opposite second surface facing away from the supporting surface, the board inverter comprising: a first board picking device for picking up the board from the conveyor, the first board picking device being linearly movable relative to the conveyor and rotatable about a first axis between a first position where the first surface of the picked board faces toward the supporting surface of the conveyor, and a second position where the first surface is substantially perpendicular to the supporting surface of the conveyor; a second board picking device, at least one of the first and second board picking devices being movable relative to the other, the second board picking device being rotatable about a second axis between a first position where the first surface of the picked board is substantially perpendicular to the supporting surface of the conveyor and the second board picking device is capable of picking up the board from the first board picking device, and a second position where the second surface of the picked board faces toward the supporting surface of the conveyor; and a first rotary driving mechanism comprising a first revolving cylinder, a first partitioning plate fixed to the inner sidewall of the first revolving cylinder, a first rotary member rotatably disposed on the first partitioning plate and a first power supply member, the first partitioning plate and the first rotary member cooperatively defining two separated first chambers in the first revolving cylinder, an outermost end of the first rotary member extending outwardly from the first revolving cylinder, the first power supply member being in communication with the two first chambers, the first board picking device being secured to the first rotary member.
