Tray transfer identification structure and material processing production line

The utility model provides a tray transfer recognition structure and a material processing production line, and the tray transfer recognition structure comprises a conveying structure which is used for driving a tray to move, and the movement path of the tray passes through a preset position; the detection structure is used for acquiring first information about whether a tray of a preset type exists at the preset position or not in the tray moving process; and the blocking structure is in signal connection with the detection structure and is used for receiving the first information of the detection structure and controlling the tray at the preset position to stop moving under the condition that the first information is' YES '. Under the condition that a plurality of detection structures and a plurality of blocking structures are arranged, a plurality of different types of trays can be processed on the same production line, so that the production cost can be reduced; and the tray does not need to stop moving i
