Mydata (MY12) error-Frame Grab and Light Curtain | 22 September, 2009

Hi,

We are getting a E-Hydra-1 Frame grabbing failed on caps and resistors and also a Light Curtain trigger X wagon.

I spoke with mydata and they indicated the light curtain might be getting set off and causing the frame grabbing failure.

I cleaned the light curtain led's and can see them turn on and off when I put my hand in front of each one.

I will continue to call them but posted here for any help.

I've run into mysterious light curtain errors before and what was happening was when the head moved across the top of the components one of the clear tape covers would flutter up and trigger the curtain then it would settle back down on top of the tape like it never moved. I don't know if this will help you but I narrowed down the culprit by pulling out the magazines one by one and running it to see if it would run with out triggering it. Hope this helps

Check to see if there's a loose cable, or something, that's randomly setting off the light curtain.

We occasionally have that problem with some of our flex or 12/16 mags in our TP9, where the tape take up clip is loose (nothing in that feeder) and is flipping around while the other feeders are advancing. It sometimes manages to flip itself just right and trips the light curtain.

Might also check around the head; I've had the vacuum tube trip the light curtain before, as well as the wires on the centering jaws.

Thanks to those that responded.

I eliminated the light curtain problem. The metal plate the light curtain pcb bolts to was bent. I had it aligned in our machine shop and it worked properly.

I forgot to mention the error was pooping up with no feeders installed. The frame grab error still shows up but the machine is picking and placing parts. I would like to know more about it.

It didn't see the ref points on the bottom of the hydra head. start by checking the camera for dirt or dropped parts. Is it a hydra camera or Linescan?

The Hydra camera is a linescan camera on our machine.

Check the reference plate on the hydra to make sure it is not cracked or delaminated. I have had problems with the glue coming loose and the plate flapping causing this same problem. check hydra camera calibrations, this to may help.
