A magazine is typically placed at the output of the conveyor line to receive the wafers. An upper suction conveyor mechanism is located above the output of the conveyor line. This mechanism absorbs the wafers conveyed along the conveyor line and releases them into the magazine.

[0055] Specifically, the conveying mechanism 10 is a narrow belt conveyor line.

[0056] The sheet transfer device proposed in the present application realizes the automatic transfer of the sheet 40 on the conveying mechanism 10 to the material box of the material box mechanism 30 through the cooperation of the conveying mechanism 10, the upper adsorption conveying mechanism 20 and the material box mechanism 30; at the same time, the upper adsorption conveying mechanism 20 adopts segmented conveying, and the conveying speeds of the first adsorption conveying mechanism 21 and the second adsorption conveying mechanism 22 are independently controlled. The first adsorption conveying mechanism 21 is only used to convey the sheet 40, and the second adsorption conveying mechanism 22 is used to convey and release the sheet 40. Therefore, when transferring the sheet 40, the first adsorption conveying mechanism 21 can quickly convey the adsorbed sheet 40, thereby improving the conveying efficiency of the upper adsorption conveying mechanism 20; and when the conveying rhythm of the conveying mechanism 10 is accelerated, the speed of the first adsorption conveying mechanism can be increased to speed up the conveying of the sheet 40 and collect the sheet in time to meet the fast-beat production requirements.
