The invention discloses an AGV-based automatic carrying system, and belongs to the technical field of AGVs. The AGV-based automatic carrying system comprises an AGV, an extrusion assembly, a moving track, a track base, a trigger assembly, a cleaning assembly, a vibration component, a driving assembly and a transfer assembly, the moving track is fixedly mounted on the top of the track base, and the AGV is slidably mounted on the moving track; According to the AGV-based automatic carrying system, an infrared sensor is installed outside, the transfer assembly is installed inside, when the AGV runs normally, the infrared sensor can effectively detect the distance between the AGV and a front vehicle, when the distance reaches a set value, the front vehicle can automatically control to start a driving motor, and the driving motor can drive the transfer assembly to send out; and due to the fact that a connecting spring cushion is arranged outside the transfer assembly, when a first transfer plate of the transfer assembly is completely conveyed out of a vehicle body, the first transfer plate can be automatically bent, at the moment, a worker or a mechanical arm can quickly transfer goods on the vehicle body to the front vehicle, and the cooperative work effect of the multiple AGVs is effectively achieved.
