Feeding and discharging device for production line

The utility model discloses a feeding and discharging device for a production line. The feeding and discharging device comprises a lifting platform, a vertical frame, a transverse moving plate, a longitudinal moving assembly and a clamp assembly. During feeding, after the clamp assembly moves downwards through the longitudinal moving assembly and the plane suction cup grabs a plate, the plate is transversely moved to the position above the conveying line of the production line on the vertical frame through the transverse moving plate, the plate is placed on the conveying line of the production line, and when feeding and discharging are completed, the clamp assembly grabs the plate on the conveying line of the production line and moves to the position above the lifting platform through the transverse moving plate; the plate is placed on the lifting platform, and discharging is completed; the clamp assembly accurately adjusts the height of the plate through the lifting platform, grabbing forming of feeding and
