Problems with a Fire-i 810C

Hello all,

 

I'm using a Fire-i 810c at a test table that checks for gold plating on some terminal pin. I have a problem that sometimes the picture becomes a little blurry which fails my part even though it is actually good. I have taken pictures even when the other stations are turned off, so nothing else is moving that could cause the part to move while the picture is being taken and it still does the same thing from time to time. I have watched the test table for a pattern of when the picture is blurry but no pattern appeared.

Is there a way that I could check for a blurry picture and then tell the camera to retake the picture?

Or maybe you have any other ideas?

 

Thank you

Depends on the picture. Can you post blurry picture and a good one?

 

Before this I will strongly recommend you check the camera mount and fixture for betterment.

Okay I have attached the two pictures. I checked the mounting and everything looks good.

The part appears to be in two different positions.  In the blurry.jpg, the part is shifted to the left.  Is the part in a different position?  That could cause it to be out of focus.

The part could be in a slightly different position, because as the table is spun around, it could move the part that sits inside a nest. Or do you mean that the part gets shifted while the camera is taking a picture?

I thought that even if the part is slightly shifted, it doesn't matter since the program has a template that it is looking for. The template is one of the pins, and a for loop is used to find three of them. Doesn't the search area shift accordingly?

 

Just wanted to add that the part can only shift horizontally and not vertically, so the height from the camera to the actual part is always the same.

Hi bluepgt,

 

Depending on how small this terminal is, very tiny motions could be causing it (people walking by, trucks outside the wall).

 

As for detecting if it's blurry, the only thing I can think of is the variability of a ROI...my thinking was if it's smushed solid red it might be less variable then the speckled black and red. If the part is shifting, though, it might be harder to get a standard ROI position.
