commercial PNP Vacuum systems

[ali_asadzadeh]

Hi
I was wondering what method or system do commercial PNP systems use for their vacuum system. I was wondering that they might use something from pneumatic systems for example companies like Festo and use an air compressor and a vacuum generator, but in that way the system is very noisy in terms of sound generation and I think by using them they wouldn't be able to achieve 180000 components per hour.

Do you have any Idea what they are doing?

Does anybody have any idea?

The older Fuji CP-6's that I run have a pair of big vane style vacuum pumps in an external box.  One for holding parts onto the nozzles and the other pump to drag away the carrier tape clippings.   I'm told that some facilities have/had much larger central vacuum pumps that ran multiple machines.  You are correct that they are very loud.  The CP6's have a 20 spindle rotary turret head,  and run about 20,000 cph.

The Fuji IP3's and Universal Genesis machines I work on both use the compressed air supply running through venturi pumps to generate the vacuum.

I don't know much about it but have read somewhere about Millisensor System. It may be the solution.

My yamaha machines generate a vacumn from compressed air.. They palce abotu 14,000 parts/hour.

Thanks guys, do you have some pictures for the vacuum parts?

Pulled some photos off the web,  as these things are all buried deep inside the machines or inside enclosures.   Not something I can get you a direct photo of.

This is the style vacuum pump that our Fuji's run...  it's about 75-100lbs for the whole assembly.
But it also needs to pull vacuum through a 20 spindle turret system.  Far more vacuum than any current production SMT machine I can think of.

The venturi vacuum generators are similar to this piece.
Apply compressed air,  and you get exhaust from the baffling and a vacuum from a side port.
As they get bigger, the air requirements grow pretty fast.

Thanks HHaase for sharing this info.
