The invention provides a real time dispatch system-based method and system for wafer batch dispatch under a machine set. The method comprises steps of setting the number of load ports of each machine under a machine set, the real time dispatch rule of each machine, and the preset time specification of each wafer batch dispatched to a corresponding machine according to effective machine information and online wafer batch data; timely obtaining information of a wafer batch which is currently processed by each machine, and calculating an idle sequence of the machines within a follow-up period of estimated time according to the number of the load ports of each machine and the information of the wafer batch which is currently processed by each machine; and sequentially updating the real time dispatch rule of each machine according to the idle sequence, and obtaining a dispatch result of each machine according to the update real time dispatch rule. According to the invention, a phenomenon that machines under the same machine set preorder the same wafer batch during preordering of wafer batches can be prevented.

The invention relates to an intelligent material allocation and binning U-shaped assembly line operation method and device. Bulk materials are contained into a storing container in a classified manneraccording to the object properties and sizes, and meanwhile, cargo delivering frames are classified and fed to an annular or U-shaped intelligent assembly operation line to be stacked; when allocation and binning are carried out, the cargo delivering frames are selected from the cargo delivering frame stacking position through the annular or U-shaped intelligent assembly operation line accordingto the logistics information, frame dividing is carried out, the divided cargo delivering frames are placed on a conveying device of the annular or U-shaped intelligent assembly operation line, and multi-station movement is carried out; cargoes needed by the cargo delivering frames are taken out from the storing container when movement is carried out by one station and are placed into specific cargo delivering frames of the annular or U-shaped intelligent assembly operation line, after all the cargoes of the cargo delivering frames are loaded, a mechanical arm is used for orderly stacking thecargo delivering frames to a tray according to cargo delivering information, then loading is carried out through a loading device, and the whole cargo allocation, binning and loading operation is completed.

The invention discloses a transfer feeding method of two material intelligent delivery conveyer lines. The transfer feeding method comprises the steps that material intelligent delivery basket coversare classified and stacked according to size and are sent to the intelligent delivery conveyer lines, and are placed on trays on the intelligent delivery conveyer lines; and when the two intelligent delivery conveyer lines are connected, the entire stack of material intelligent delivery basket covers are lifted from the tray on one intelligent delivery conveyer line through a lifting device and are then sent to the tray of the other intelligent delivery conveyer line through one conveying cylinder, and transfer of the material intelligent delivery basket covers on the two intelligent deliveryconveyer lines is achieved through cooperation of the two devices.
