The present invention relates to an industrial robot process cloud system and a working method thereof. The industrial robot process cloud system comprises an industrial robot control system integrated with a human machine interaction layer HMI, a motion planning control layer Motion and a servo loop control layer Servo, and further comprises a cloud server, wherein the cloud server comprises a process expert system. The human machine interaction layer HMI and the motion planning control layer Motion realize data interaction with the cloud server by means of a network, after the human machine interaction layer HMI inputs operation information, the operation information is transmitted to the cloud server, and a specific robot operation program is generated and downloaded into the industrial robot control system by means of the network. The present invention realizes cloud processing performed to process experiences on various operation types of industrial robots, the process expert system is formed, data interaction and real-time evolution learning of the process expert system are realized by means of the network, the user can conveniently call in real time the robot process program which best satisfies actual requirements and the changeover production efficiency is improved.
