Feeding and discharging mechanism and product double-face detection device

The utility model relates to a feeding and discharging mechanism and a product double-face detection device. The feeding and discharging mechanism comprises a feeding disc used for containing products, a feeding opening, a feeding assembly, a first conveying assembly, a suction cup positioning assembly, a discharging assembly and a discharging opening. The first conveying assembly comprises a first receiving disc, a second receiving disc and a second driving assembly. The second driving assembly is used for driving the first receiving disc and the second receiving disc to move in the Y direction at the same time. By arranging the first conveying assembly, the first receiving disc and the second receiving disc can be located below the feeding station and the clamping station at the same time or located below the clamping station and the discharging station at the same time, so that a detected product feeding disc on the clamping station and a to-be-detected product feeding disc on the feeding station can be su
