The overmolding system of claim 1, wherein the positioning mechanism includes a movable assembly movable relative to the frame, a lift-up charging assembly mounted on the movable assembly, the lift-up charging assembly being positioned at a discharge port of the discharge mechanism, and a rotational positioning assembly positioned above the lift-up charging assembly, the lift-up charging assembly and the rotational positioning assembly being configured to angularly position individual materials, the movable assembly being movable relative to the frame with a discharge position positioned below the rotational positioning assembly and a take-up position for the movement of the material by the movement mechanism.

10. The overmolding system of claim 9, wherein the moving assembly comprises a drive cylinder, a moving stage coupled to a drive shaft of the drive cylinder, the moving stage being movably mounted on two movable bars at both ends;

11. The overmolding system of claim 9, wherein the discharge mechanism is a vibratory pan, the jacking charge assembly being flush with a discharge height of a discharge port of the vibratory pan;

and/or, the material moving mechanism comprises a material moving sliding rail arranged on the frame and a material moving manipulator slidably arranged on the material moving sliding rail, and the material moving manipulator can move at the material discharging position and the material taking position.
