“…The mating tolerance is the distance required for successful mating between the female and male connectors. In the paper: "Tolerance Dataset: Mating Process of Plug-in Cable Connectors for Wire Harness Assembly Tasks", Yumbla et al [17] presented a study of the mating tolerance for seventy different types of terminals for wire harnesses. Their objective was to determine the tolerance for different types of connectors.…”

“…They developed a dataset that can be used to design and select the right robotic manipulator control for a robot. They concluded that their dataset, obtained using a CAD system, has a good tolerance [17]. A related study, titled: "Robotic Wire Pinning for Wire Harness Assembly Automation", was developed by Tunstel et al [13] using a cobot to establish a possible automation solution to insert a wire in an electrical terminal.…”

“…It is also a process that a cobot can carry out. In the papers by Tunstel et al [13] and Yumbla et al [17], they carry out their research on the tasks of connecting the male-female connectors. Nguyen and Yoon [19] and Heisler et al [22] work on the cobot's task to place a wire harness on an assembly board.…”

“…In addition, in the paper of Yumbla et al [17], they presented the mating tolerance needed to reduce the error when a cobot connects a female connector to a male one since many variables can cause the connection not to be effective, such as thicknesses, shapes, etc. In another paper by Yumbla et al [18], they complemented their previous work.…”

Wire Harness Assembly Process Supported by Collaborative Robots: Literature Review and Call for R&D

The wire harness assembly process is a complicated manufacturing activity, which is becoming more complex because of the evolving nature of mechatronic and electronic products that require more connectors, sensors, controllers, communication networking, etc. Furthermore, the demand for wire harnesses continues to grow in all industries worldwide as the majority of equipment, appliances, machinery, vehicles, etc., are becoming “smart” (i.e., more mechatronic or electronic). Moreover, most of the wire harness assembly process tasks are done manually, and most of these are considered non-ergonomic for human assembly workers. Hence, the wire harness manufacturing industry is faced with the challenge of increasing productivity while improving the occupational health of its human assembly workers. The purpose of this paper is to conduct a literature review exploring the state of the use of collaborative robots in the wire harness assembly process due to their potential to reduce current occupational health problems for human assembly workers and increase the throughput of wire harness assembly lines, and to provide main findings, discussion, and further research directions for collaborative robotics in this application domain. Eleven papers were found in the scientific literature. All papers demonstrated the potential of collaborative robots to improve the productivity of wire harness assembly lines, and two of these in particular on the ergonomics of the wire harness assembly process. None of the papers reviewed presented a cost–benefit or a cycle time analysis to qualitatively and/or quantitatively measure the impact of the incorporation of collaborative robots in the wire harness assembly process. This represents an important area of opportunity for research with relevance to industry. Three papers remark on the importance of the integration of computer vision systems into a collaborative wire harness assembly process to make this more versatile as many types of wire harnesses exist. The literature review findings call for further research and technological developments in support of the wire harness manufacturing industry and its workers in four main categories: (i) Collaborative Robotics and Grippers, (ii) Ergonomics, (iii) Computer Vision Systems, and (iv) Implementation Methodologies.

“…Thus, a major challenge in joining is the filigree character. As the pose accuracy of commercially available, conventional industrial robots is in the range of several millimeters [25], they may be too imprecise for joining specific cable variants. In addition, the cable shape, at least the cable end or the connector end, respectively, has to be determined precisely before joining.…”

The assembly of cables in industrial production is still a largely manually performed task. Therefore, automatic cable assembly offers much potential in terms of efficiency. The major challenge of automating this task lies in the formlessness of the cables, which entails unknown and inconstant states of the assembly objects. In this paper, a process chain and a concept are presented for the automated cable assembly in an industrial context. The process chain consists of five process steps, which are used to structure existing approaches and system configurations for automated cable assembly from a production technology perspective. The emphasis is on the coverage of the process steps and the system technology. The presented concept represents an approach for robotic cable assembly focusing on the flexibility to process multiple product variants. Basis for the ability to handle a variety of variants is the avoidance of a forced shape on the cables. For this approach, system technology as well as challenges and possible solutions are presented.
