For tests other than comparative inspections
If you are producing the same product in large quantities and the shape of the product is always stable, comparative inspection is the best inspection method. Therefore, we do not explain inspection methods other than comparative inspection when we first make a proposal. However, if the material or the process is not stable and the finished product is [...]...
[Introduction to Image Processing for Machine Vision and Image Inspection 2017] Released
It was released on April 10, 2017, and I had the pleasure of writing the preface to this issue. I am pleased to share with you the need to put aside the technical details of image processing technology and put it to work in the field on a day-to-day basis.
Sales of single software products
Currently, we (basically) do not sell the software as a stand-alone product. When the Windows operating system is upgraded, we will be able to support new projects so that FIS-100 will work. Now [...].
FIS-100 AND LED POINT LIGHT SOURCE
OUR SOFTWARE FIS-100 WILL TEST IF IT IS THE SAME AS USUAL. HOWEVER, IT IS NOT PATTERN MATCHING. SINCE THE IMAGES DO NOT ALWAYS LOOK 100% THE SAME, WE USE STATISTICAL METHODS TO CHECK IF THE IMAGES ARE ALMOST THE SAME AS USUAL, ALLOWING FOR VARIATIONS [...].
IT'S NOT ENOUGH TO BE ABLE TO SEE THE NG PART.
SINCE VISUAL INSPECTIONS ARE CONDUCTED TO PREVENT THE OUTFLOW OF NG PRODUCTS, IT IS ONLY NATURAL TO MAKE SURE THAT NG PARTS ARE CLEARLY VISIBLE TO THE CAMERA. HOWEVER, IF THE CAMERA ALSO CLEARLY SHOWS OK PARTS OTHER THAN NG PARTS, IT WILL BE DIFFICULT TO DRAW A LINE BETWEEN OK AND NG PARTS. THEREFORE, IT IS IMPORTANT THAT THE CAMERA'S [...]...
Chip Saw Inspection Demo
We often experiment with chip saws and gears, as these are the most common themes these days. It works well with our versatile software FIS-100 and provides a great return on investment. We have uploaded a video of the demonstration situation on YouTube, so please [...].
Wavelengths of Light, Part 2
In the last issue we discussed lighting in general terms. We have been experimenting with various wavelengths of lighting. In terms of visible light, we have tried red, green, blue, white, etc. We have also tried ultraviolet light, and in terms of visible light, we have tried red, green, blue, white, etc. The conclusion we have reached is that white light is basically the way to go. Of course, it's not as easy as it looks [...].
Wavelengths of Light Part 1
This is a general discussion of light wavelengths. Sunlight is white, so it can be divided into long and short wavelengths, and even within white it contains many different kinds of light. You can separate the colors through a prism, but red light, which has a longer wavelength, is not refracted as much and is scattered to a lesser degree [...].
Solder or solder leakage inspection
When soldering or brazing by hand, the shape is often unstable. I had a theme of visual inspection to see if the soldering was actually done properly, so I tested the work sample. As I expected, there was a large variation [...].
Industries where robots can be utilized
The other day, I was talking with the president of a company that deals with deburring and polishing robots, and he mentioned several similarities with the visual inspection industry we are in. What he meant was: 1) Basically, they are trying to use robots to replace work that can be done by humans [...].
