Abstract

Industry 4.0, a term invented by Wolfgang Wahlster in Germany, is celebrating its 10th anniversary in 2021. Still, the digitalization of the production environment is one of the hottest topics in the computer science departments at universities and companies. Optimization of production processes or redefinition of the production concepts is meaningful in light of the current industrial and research agendas. Both the mentioned optimization and redefinition are considered in numerous subtopics and technologies. One of the most significant topics in these areas is the newest findings and applications of artificial intelligence (AI)—machine learning (ML) and deep convolutional neural networks (DCNNs). The authors invented a method and device that supports the wiring assembly in the control cabinet production process, namely, the Wire Label Reader (WLR) industrial system. The implementation of this device was a big technical challenge. It required very advanced IT technologies, ML, image recognition, and DCNN as well. This paper focuses on an in-depth description of the underlying methodology of this device, its construction, and foremostly, the assembly industrial processes, through which this device is implemented. It was significant for the authors to validate the usability of the device within mentioned production processes and to express both advantages and challenges connected to such assembly process development. The authors noted that in-depth studies connected to the effects of AI applications in the presented area are sparse. Further, the idea of the WLR device is presented while also including results of DCNN training (with recognition results of 99.7% although challenging conditions), the device implementation in the wire assembly production process, and its users’ opinions. The authors have analyzed how the WLR affects assembly process time and energy consumption, and accordingly, the advantages and challenges of the device. Among the most impressive results of the WLR implementation in the assembly process one can be mentioned—the device ensures significant process time reduction regardless of the number of characters printed on a wire.

Highlights

The authors of this paper considered the process of the assembly of the industrial enclosure, which results in a complete control cabinet in the final part of the process
The first aspect is connected to training the neural network, which is a significant part of the method and device, described in the previous section
The authors decided to analyze the duration of the operations and logistics processes that are significant from the point of view of applying the Wire Label Reader (WLR) onto the wiring production process

Summary

Introduction

The authors of this paper considered the process of the assembly of the industrial enclosure, which results in a complete control cabinet in the final part of the process. Such a process, conducted in the traditional way, involving direct human reading and plenty of on-hand operations, is time- and energy consuming and subject to mistakes in its installation. The assumption of the authors is that the production process of control cabinets is preceded by the automatically supported production of wires and the assembly of wires is enhanced with the use of a dedicated software system. It is worth mentioning that the launch of the world’s first fully automatic crimping machine equipped with a twister device was reported in 1999 [2]
