One end of the rotating platform 19 extends out of the sliding platform 5 and is connected to the turntable 20. Two support plates 3 are provided on the turntable 20.

Every time the silicon wafers are loaded into the inner side of the buffer box 4, the buffer box 4 is lifted upward by a pitch distance again to achieve the silicon wafer stacking and caching effect. When the silicon wafers on the buffer mechanism are full, the buffer mechanism rotates 90 degrees so that the silicon wafers fall onto the correction mechanism. The correction mechanism pushes the silicon wafers to prepare for the robot to pick up the silicon wafers. Among them: the distance of one pitch is the distance between two adjacent support rods 11;
[0040] The servo motor 14 drives the bevel gear 16 to rotate, and the bevel gear 16 drives the bevel gear 2 17 to rotate. The bevel gear 2 17 rotates through the drive shaft 18, the rotating table 19 and the turntable 20.
