Production line and conveying system

The embodiment of the invention provides a production line and a conveying system. The transport system includes: a stage; the conveying mechanism is used for driving the carrying table to move in the conveying direction; the conveying mechanism comprises a first operation conveying section; and a first positioning mechanism. Wherein the first positioning mechanism comprises at least one first positioning guide rail which is fixedly arranged relative to the conveying mechanism; the first positioning assembly is matched with the at least one first positioning guide rail and used for limiting movement of the carrying table in the direction perpendicular to the conveying direction when the carrying table moves to the first operation conveying section. When the carrying table moves to the first operation conveying section, movement of the carrying table perpendicular to the conveying direction is limited through the first positioning mechanism, so that the workpiece cannot move in the direction perpendicular to t
