EIZO Installs Its Own IP Decoding Solutions to Maintain Visibility of Production Processes

EIZO headquarters in Hakusan, Ishikawa Prefecture, Japan, is home to the planning, development, quality control, manufacturing, and after-sales support processes for its various product lines. It is this unique integrated production that enables EIZO to bring high-quality solutions to users around the world. At the factory, where LCD monitors and visual solutions are manufactured, EIZO has installed its very own IP decoding monitor and box solutions that are connected to IP cameras for keeping eyes on production processes and ensuring employee safety. Introducing these solutions now allows EIZO to maintain visibility of the production floor in real time, which provides many benefits as a result.

Challenge 1

Lack of Visibility in the Restricted Entry Clean Room

Easy to Check the Safety of Workers Remotely

Clean room from the outside

Operations inside the clean room

EIZO's factory has its own ISO Class 1* clean room where touch panel monitors and other sensitive products are produced. Class 1 is the highest classification of ISO 14644-1. In order to maintain the strict standard for cleanliness, only a small number of workers are permitted in this area. This restricted entry made it difficult for supervisors outside of the clean room to monitor progress and check on the safety of the staff inside. That is where the DuraVision FDF4627W-IP comes in - this large 46-inch IP decoding monitor was installed in the management office which enabled supervisors to check on progress and monitor worker safety from outside the clean room.

* ISO 14644-1 Class 1 specifies a maximum concentration of particles of 0.1 micrometers per 1 m³ of air.

Employee Voice 　 Yuka Wakabayashi, Leader Manufacturing Department, EIZO Corporation     Worker placement changes on a daily basis when we carry out high-mix low-volume production. We are keeping track of who is in what area through data management but being able to also see video in real time gives us even more reliable ways to manage the production floor. The clean room is not an area we can easily go in and out of, so it's incredibly useful for us to be able to track production by looking at what's on the screen. This helps us with process control.

Challenge 2

Difficulty of Tracking Operation Status and Unmanned Production Processes

Increased Visibility of Unmanned Process for Efficient Use of Labor and Safe Operation

EIZO has been working towards digital transformation (DX), having adopted its own automatic inspection system that uses artificial intelligence (AI) in the monitor production process.

*A process where the monitor is left on for an extended period to confirm stability.

Since the inspection process is conducted in an unmanned darkroom, production staff are not able to go inside and watch over the process at all times. To solve this, EIZO installed an IP camera inside the inspection room that is connected to the IP decoding box DX0211-IP and 31.5-inch 4K monitor mounted on the wall outside the room. With just a LAN cable between the camera and the IP box, the monitor displays images from inside the inspection room from over the network. This has allowed EIZO to detect and address abnormalities early and reliably maintain smooth operations.

Manager Voice 　 Shinichi Yasukawa, Section Manager Manufacturing Department, EIZO Corporation     Before, having an analog camera solution gave us a hard time, as it required large-scale construction work to rewire things throughout the factory. Our factory has evolved significantly over the years and now the IP decoding solution is a part of that evolution. The IP decoding monitor and box can easily add the element of "visibility" to any existing factory. We are proud to be using our own products. The convenience of being able to display video by just connecting a camera with a LAN cable without a PC is invaluable.

Challenge 3

Difficulty for Supervisors to Check Process Progress

More Efficient View of Production Processes

The latest additions to EIZO's factory line are automated processes which use AI to save on labor. Since they are usually unmanned, IP decoding monitors are installed at the work areas which directly follow these processes in the production line, where staff conduct visual inspection of products. In addition, since the assembly, inspection, and packaging processes are conducted across multiple floors, this allows production staff to easily check the progress of the previous process, make appropriate personnel adjustments, and effectively manage the backlog, all of which leads to improved production efficiency.
