Joint conveying device

The utility model belongs to the technical field of assembly part conveying, and particularly relates to a connector conveying device which comprises a lower-layer line body and an upper-layer line body which are vertically arranged in a spaced mode, and in the connector conveying direction, the two ends of the lower-layer line body extend outwards by a set distance relative to the two ends of the upper-layer line body so that the two ends of the lower-layer line body can be in a step shape. And the pipe joint is arranged at an interval with the conveying tail end of the lower-layer line body and is used for discharging the conveying tail ends of the lower-layer line body and the upper-layer line body. Firstly, the pipe joint is conveyed to the conveying tail end from the conveying head end of the upper-layer line body and the conveying head end of the lower-layer line body, and then the joint located at the conveying tail end is conveyed to a device of the next assembly procedure through the robot carrying s
