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 [...].
Inspections are speedy
The other day, I had the opportunity to talk with a manager of a contract visual inspection company. He told me that the first step in training inspectors is to get their eyes accustomed to the high speed at which good products are being produced. As they do this, they learn to adjust their eyes, body movements, and awareness [...].
Inspection of casting castings
THERE IS A GREAT NEED FOR INSPECTION OF CASTINGS. HOWEVER, IT IS TRUE THAT SUBTLE NG IS DIFFICULT TO DISCERN. VISUAL INSPECTORS ACTUALLY INSPECT THE WORKPIECE WHILE TILTING IT. THIS MEANS THAT: 1. THE LIGHTING IS FROM ONE DIRECTION AND THE WORKPIECE IS INSPECTED MANY TIMES BY TILTING IT. 2. 2. INSPECT THE WORKPIECE FROM VARIOUS ANGLES [...].
Happy New Year 2017!
Finally, we are off to a great start in 2017. I would like to take this opportunity to thank you all for your continued support this year! To sum up last year, the economic environment was not so good, and we felt that our budget for capital investment, especially for visual inspection, was limited [...]...
