Abstract
<div class="section abstract"><div class="htmlview paragraph">With the growth of Industry 4.0 in recent years, Augmented Reality (AR) technologies are changing the way operators work by increasing their efficiency and operational performance. A common use of AR is providing operators helpful work instructions for assembly by presenting relevant digital information in the context of the physical environment. These AR experiences can be viewed via several devices such as mobile, wearable, and stationary devices, each being useful for different applications. While in the experience, instructions are provided by means of 3D animation, text, images, and interactive buttons, all of which are directly overlaid onto the physical product or equipment being worked on. This work presents a closed-loop, enterprise connected, AR system for post end Printed Circuit Board (PCB) assembly work instructions. The system is designed to work with a stationary device, allows for varying types of PCB”s, provides overlaid instruction, and logs important information to an enterprise system, such as overall cycle time, step cycle time, number of errors, type of error, and who performed the assembly. A comparison was made for single cell manual assembly PCB work instructions using both an Industry 4.0 driven system and a more traditional manufacturing system which used packets, tracers, Manufacturing Execution System (MES), and PDF instructions. Discovered benefits of an enterprise connected AR system included increased throughput and utilization, improved communication between operators and support, reduced overtime costs, reduced defects, reduced non-value-added secondary inspections, nearly 50% increase in ergonomics, reduced labor due to rework, and improved corrective actions due to granularity between steps compared to total operation. This AR driven solution transformed the single cell manual assembly to be more informed, make better decisions, and help operator productivity.</div></div>
