Automatic opening plate placing mechanism

The utility model relates to an automatic open plate placing mechanism which comprises a frame body, an open plate, a male die, a conveying mechanism, a male die pushing mechanism, an open plate pushing mechanism and an open plate supporting mechanism, the conveying mechanism and the male die pushing mechanism are arranged at the two ends of the frame body respectively, and the open plate supporting mechanism is fixed in the middle of the frame body. The open disc is correspondingly located between the conveying mechanism and the male die pushing mechanism, the open disc is of a disc-shaped structure with one end open, the open disc has a first state arranged on the conveying mechanism and/or a second state arranged on the open disc supporting mechanism, and the inclination angles of the first state and the second state of the open disc are different. The open disc pushing mechanism is correspondingly located below the open disc supporting mechanism, and the open disc pushing mechanism is used for lifting the
