The application discloses a semiconductor wafer bin conveying system and a control method thereof, and relates to the technical field of semiconductor manufacturing automation. The system comprises a conveying unit and a material placing unit. The improvement lies in that the bottom of a wafer bin body is provided with three positioning grooves in isosceles triangle distribution, forming a mistaken orientation prevention structure; and the transfer frame and the material placing frame are respectively provided with a first set and a second set of limiting protrusions corresponding to the positioning grooves. The two sets of protrusions are configured to be selectively and sequentially clamped with the positioning grooves at the bottom of the same bin body during the conveying process, so that the anti-interference positioning handover from grabbing to placing is realized. The application eliminates the positioning collision risk between the conveying mechanism and the fixed station from the mechanical structure, and ensures the uniqueness of the direction of the wafer bin through the asymmetric geometric design. Meanwhile, the material placing frame can be integrated with elastic air supply and pressure sensing detection functions, realizing higher automation and reliability.
