Claim 11:
12. The wafer flipping method by wafer transfer robot of claim 10, wherein the placement of wafer comprises the following steps: after the first jaw clamping arm takes out the wafer from the pre-drying unit, the horizontal transfer carriage drives the first jaw clamping arm to make transverse motion away from the drying unit; the rotating platform drives the first jaw clamping arm to rotate to the side close to the drying unit until the wafer reaches a horizontal state, and the first vertical lifting shaft drives the first jaw clamping arm to move vertically to a certain position; then the horizontal transfer carriage drives the first jaw clamping arm to move laterally towards the drying unit until the wafer is positioned above drying unit; the first vertical lifting shaft drives the first jaw clamping arm to move vertically downwards until the wafer is positioned on the designated mechanism inside the drying unit; the first jaw clamping arm releases the wafer so that the wafer is positioned on the designated mechanism inside the drying unit.
