The PCB board 2 after the cutting moves to transfer station 11 by carrier plate 32, and unloading suction nozzle 224 absorbs PCB board 2 after the cutting and waste material board limit, and unloading suction nozzle 224 is under the drive of grabbing linear module 221, moves to the top of waste material groove 24, and the unloading suction nozzle 224 of part absorption waste material board limit releases the vacuum, and under its self gravity effect, the waste material board limit falls into the waste material groove 24 that is located its below to slide to the outside of waste material groove 24, and the PCB board 2 after the cutting is released on the unloading conveyer belt 23, so the clearance of waste material board limit is comparatively convenient, and the efficiency of board separator 1 divides the board further promotes.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
