Abstract: A magnetic tile automatic alignment conveyor is introduced. The conveyor includes a conveying unit and a calibration unit.The purpose is to realize the position correction of the magnetic tile on the first conveyor belt.Namely，the length direction of the conveyor belt parallel to the two ends of the magnetic tile to avoid the bias of the magnetic tile on the first conveyor belt，resulting in the magnetic tile being ground into a parallelogram or blocking the feed port of the grinding units at both ends.

Key words: magnetic tile, conveyor, high frequency vibrator, bias
