“…The actual results of testing the crimping quality of transmission line fixtures with the designed system are shown in Figure 3: As can be seen from Figure 4, the trajectory of robot joint angle automatic online and offline under the method in this paper is close to the actual value, and the error is small, while the trajectory of robot joint angle automatic online and offline under the method in reference [3] and the method in reference [4] is quite different from the actual value. This is because the method in this paper ensures that the planned path is the shortest distance by improving the S-shaped trajectory planning method, and when the robot encounters obstacles, the fast planning of straight and turning paths can quickly bypass the obstacles.…”

“…References [3] proposes a design scheme of robot automatic feeding system based on machine vision. The system uses the camera to collect the shape, size and pose information of the workpiece, the image software of the upper computer to process and match the features with the set standard template, and finally the industrial robot controlled by PLC to quickly capture the obtained pose information.…”

The shape and parameters of hardware are diverse, so the robot needs to have high precision to ensure the correct docking of hardware and apply appropriate force. In order to avoid damaging the hardware fittings, this paper designs an automatic online and offline system for the quality inspection robot of the power transmission line hardware fittings. The hardware structure includes user layer module, decision layer module, execution layer module and equipment layer module. The four functional modules work in coordination to enhance the robot trajectory planning effect. In the software part, the S-shaped trajectory planning method is improved to ensure the shortest planned path distance, and when the robot encounters obstacles, it can quickly plan straight and turning paths to effectively avoid obstacles, thus completing the design of the robot automatic online and offline system. The experimental results show that the trajectory error of the proposed method is less than 0.1rad.

“…During the development process of the past hundred years, from the beginning of manual assembly relying on the experience of technicians to the 1980s when assembly sequence was reasonably planned with the help of computer, to the present intelligent assembly machine is completed independently. Intelligent assembly reduces manual participation and thus completes work efficiently and accurately [1]. In traditional assembly system, the development and design cycle is long and the cost of prototype trial production system is high.…”

The debugging quality in the debugging stage of the digital production line directly affects its processing accuracy. Due to the rich and varied production scenes and complex equipment associations, the general production debugging plan has a long cycle. Therefore, this paper adopts digital twin technology to apply to the traditional assembly system design process, adopts NX, MCD, TIA and other design methods. Firstly, builds a digital virtual model of the assembly platform; Secondly, the application of electromechanical concept design module to achieve virtual simulation of the assembly process; In the TIA project environment, the logic control program of the PLC controller is written; Then, build a physical system based on a virtual model; Finally, virtual and real system integration is achieved through communication connections. The research results show that the traditional assembly system from design, debugging and application cost is higher, cycles are usually within three to five months, assembly platform based on the digital twin technology can significantly reduce the design cycle of assembly system and research and development costs.

Manufacturing industry is facing new challenges in that fast-changing demands for products and services from customers push manufacturers to be more flexible and adaptive. The concept of batch-size-of-one production is presented in this paper, which defines a fully automated, highly customised, and short lead time production model. The desired batch-size-of-one production model is a promising solution for the above challenges in manufacturing industry, especially for highly customised or families of similar products like in the mobile phone industry. Along with the concept, we introduce a novel control method that enables the desired batch-size-of-one production model in operation of robots in manufacturing and assembly systems. The strategy was developed for robot control based on a distributed system to enable industrial robots to receive job commands on the fly and to conduct different jobs without the need for reconfiguration and reprogramming and without overheads. The aim of the research is to create the basis for a fully automated robot flexible assembly cell to perform batch-size-of-one assembly tasks with minimal human involvement by eliminating interruptions from the reconfiguration and reprogramming processes. The proposed strategy has been validated in practice in a multi-robot, multi-product flexible assembly cell.
