Manufacture Of Inspection Equipment Case

It is the manufacturer of three types of cases, one case containing Raspberry Pi 4 Model B and PoE HAT, which will be mounted on vision inspection equipment of the production line, and one case containing Raspberry Pi HQ camera or 8M camera.

This time, we modified JDUO 4C, a cluster case of Joontech.

These days, the Raspberry Pi product line is not limited to prior development, but it seems that it is increasingly being put into the production line to control equipment or commercialize it at all.

It’s proof that it’s expanding its use in various fields.

Case with Raspberry Pi 4 Model B and PoE HAT

It is difficult to obtain PoE HAT with the launch of PoE+ HAT, but unlike PoE HAT, the cooling fan position of PoE+ HAT is largely skewed to the right, not just above the CPU of the Raspberry Pi 4 model B.

As a result, it is difficult to directly cool the CPU, so if PoE+ HAT and Raspberry Pi 4 Model B are accommodated together in the case, high heat generation will stop the operation.

For this reason, Joontech did not develop a case that accommodates PoE+ HAT and Raspberry Pi 4 Model B together.

Fortunately, the client chose PoE HAT to avoid problems caused by fever.

Looking at the structure, first, insert a 40-pin dual header (Male) into the Raspberry Pi’s GPIO port and a 4-pin dual header (Male) into the PoE power supply pin.

Then, the Raspberry Pi is seated on the case and fastened using a screw and a PCB support (Female).

Next, plug the PoE HAT into the two dual headers (Male).

At this time, when the bottom surface of the PoE HAT and the PCB support (Female) come into contact with each other, screw it and fix it.

Finally, put the cover on the case and screw it in the front of the case to finish the assembly.

The structure mentioned above has the advantage of reducing the size of the case.

The client was also able to produce it on its own, but it was difficult to reduce the size of the case.

As the size of the case increases, the quantity that can be mounted on the inspection equipment decreases, and the reliability of the inspection decreases.

The manufacturer, who was looking for a way to reduce the size of the equipment, accidentally saw JDUO 4C and requested us to manufacture it.

Structure of Camera Case

The structure of the Raspberry Pi HQ camera case is to screw the camera and the case at once.

Since the size of the case should be small again this time, the space of the camera board was reduced as much as possible.

In the case of the Raspberry Pi 8M camera case, unlike the Raspberry Pi HQ camera case, the board and the front case were first screwed, and then the rear case was covered and screwed to finish the assembly.

The board size of the Raspberry Pi 8M camera was too small to take the same method as the HQ camera case.

Closing remarks．．．

Raspberry Pi’s influence seems to be expanding enough to be applied to the field.

At first, individuals, schools, or research institutes were the main ones requesting us to make Raspberry Pi cases, but now the number of requests from companies is increasing.

It is not possible unless the stability and performance of the board are guaranteed because it is used to mass-produce final products or control equipment different from previous research purposes.

We think Raspberry Pi is recognized for its performance and reliability to the extent that it is not unreasonable to use in the field.

Of course, in order to expand its use in the field, there must be a mountain to overcome: reinforcement of power supply design and changes in storage systems, but it is true that board design has improved completeness compared to the beginning.

In the future, I plan to post the making of various single board computer cases, so please pay attention and I will end here.
