[RICOH SC-10A internal case study]

As the manufacturer of medical devices, our customers are doctors and patients.
Therefore, it is necessary to ensure that no defects are produced, and strict standards are set.

In the past, in order to maintain strict quality control, it was often the case that skilled workers were assigned to the manufacturing process.

Nowadays, there are not only skilled workers, but also due to the migration of people,it is necessary to employ people with a relatively short working period to proficiently maintain the quality.

In which case, it is no longer possible to manufacture only by experience and memory, so we are maintaining product quality using the RICOH SC-10A Work Assistance Camera System, which can perform automatic judgment.

"The RICOH SC-10A is used in the manufacturing process of the incubator unit used for blood test equipment, which warms blood to the same temperature as body temperature.

There are a total of 11 screw tightening processes, which have two issues.

1. Is the order of tightening the screws correct?
2. Are the screws tightened with the correct torque setting?

The SC-10A is used for the work steps that must guarantee these two points.

Such problems can also be solved by using automatic screw tightening machines, which are expensive and difficult to install in terms of cost effectiveness for a high-mix, low-volume manufacturer like ourselves."

Workers have to do various things to maintain quality.
Thanks to the introduction of RICOH SC-10A, human error has been reduced and quality maintained.
The attention and effort of this process can be used elsewhere, increasing overall efficiency.
In addition, even unskilled workers were able to engage in the work quickly and efficiently.

Mr. Hamano of FUJIFILM Techno Products Co., Ltd.

Before the installation, the worker wrote the OK / NG judgment on a check sheet, but the history of the automatic judgment of RICOH SC-10A can now be recorded as evidence on the server.
Paper usage has decreased, and the burden on workers reduced.

Since the RICOH SC-10A detects mistakes and does not proceed to the next stage until it is corrected, it can be said that work mistakes have been completely eliminated.
Since the intention was to create an environment where we could not make a mistake, we are glad to install it.

The RICOH SC-10A is a small, lightweight integrated controller equipped with its own operation system and can connect with abundant interfaces such as LAN, USB, I / O, etc.
In addition, its price was reasonable and attractive to us.

In the RICOH SC-10A, the master image is registered and the model is switched by reading the barcode on the slip.
Since product specifications change depending on the destination, we manufacture more than 100 types of products, which can be switched with just one SC-10A.

The RICOH SC-10A and electric screwdriver are used in conjunction with each other.
The output of the driver is only I / O, but there are few cameras that can receive the output as it is, making it necessary to use the sequencer once or switch to serial communication.
In contrast, it was good that the RICOH SC-10A was an open collector and could receive the I / O output as it was.

After all, the most important point in judging with a camera is the lighting environment.
We were able to make use of the know-how of the past.
In the past, I used image recognition with a camera, and even if I moved the work space a little, the judgment did not go well, so I made an enclosure on the assembly table so that the same judgment can be made in all environments.
Regarding lighting, we devised a tape LED so that we can add it immediately if there is insufficient light.
