RFI SHIELD CLIP placement | 25 February, 2020

Hello everybody,

you see, I have a problem with the placement of these RFI SHIELD CLIPs (PN: S0941-46R) I simply cannot place them using the machine, so far I have placed them by hand in the prototypes but I am about to start production and I need to place them the pick & place machine (Hanwha SM482)

I've tried with the nozzles 040 and 065 but one does not lift it and in the other sometimes the clip gets stuck

Have any of you had experience with this type of clips in these machines? How to use a special nozzle, or do you have any advice?

I appreciate your comments and suggestions

Have you tried changing the Z speeds and/or wait times to help the 040 nozzle?

Yes, I have tried it but apparently the clip is very heavy for the 040 nozzle, I will continue testing to see how it is solved

Thank you

I haven't used these clips, or this machine, so...

But..in general, I'd use as large a nozzle as you can that fits the pick area of the clip. That should give you the best opportunity at lifting the clip.

If the machine has a gripper nozzle (with little plier like jaws) and they fit around the part, that might be a better option.

Might also determine how many of these need to be placed, versus panel run time. It could come out to being more efficient to have the operator place them at a manual place station after pick/place. If, say, placing them takes 2 minutes per panel, and run time is 5 minutes per panel, it would seem like something that wouldn't bottle-neck. If the alternative is a large amount of lost time trying to make the machine do it, or excessive rework because the machine isn't able to do it repeatably, manually placing might be better.

Course, if it takes 5 minutes to place them, and two minutes to run the panel, you'll run into an instant bottle-neck, and definitely want to run down as many automated solutions as possible.

Cheers, ..rob

If you tried the nozzles on your machine and none worked, it is time to order a custom nozzle for the part.

I think that will be the option I will take, thanks!

We had a similar type of part that gave us trouble. Our solution was an o-ring attached to the end of the nozzle, we used a type of shoe-goo to adhere the o-ring to the nozzle. May be cheaper than a custom nozzle.
