CP40 nozzle holder - looking for some dimensional data

[Alexander Willer]

Hello,

currently I am in the process of designing a Pick&Place head.

To design the mount for the nozzle holder I am now looking for a drawing or at least for some dimensions of the Samsung CP 40 nozzle holder as you can buy it, e.g. at aliexpress.

I found the following picture (just for reference), but its not preicse enough if I just try to read the ruler shown in the photo:

https://photos.google.com/share/AF1QipNf51Lg7FIDBt9WnFzOSIOiuP85EMGo3OfiLwLOSzZ7gYDK0ScD9Q556YniRxJwOg?key=WmxGOG5WZmNMWGRSRzRhM1I0cVhWNUlfQnpDWDNn

Has anybody one of these holders and may help by measuring the follwing dimensions?

• M5 thread length
• Diameter and length of the "alignment part" directly after the thread (I think it is for alignment of the holder inside its mounting block?)
• Overall length of the holder, maybe also with a attached nozzle
  

The other dimensions are not that relevant for CAD design-in, but if you have those, I would be happy about knowing them.

Thanks in advance!

Alexander

My 3d model: https://yadi.sk/d/gC-3EnDbrxg6b

The dimensions are exactly the same to the actual size.

But this drawing of holder without the nozzle.

The nozzle is available, but I do not have time to draw.

Very nice, thanks! I had a 3D model of this part I had created, but it didn't have this much detail. Did you create this model yourself, or did you get it from somewhere?

[Михаил Юров]

I built this 3d model by myself , having in hand the nozzle holder and an electronic caliper.

[Juha Kuusama]

To double check, here are what I measure:

> M5 thread length

7.3mm, including the small portion before the "alignment part" that has no thread. Thread itself 6.3mm

> Diameter and length of the "alignment part" directly after the thread

7.0mm

> Overall length of the holder, maybe also with a attached nozzle

36.0mm without nozzle, with a nozzle 43.4mm. The spring gives 3.0mm movement.

Hi all, I've deleted the post with the dimensions image as it contained a copyrighted image from the LitePlacer website. You can see the image on the LitePlacer store at: http://www.liteplacer.com/shop20/index.php?route=product/product&product_id=66

This isn't a big deal, nothing to worry about. But it's important to give credit for content from other websites. This way the author is credited properly.

Does anyone have info of O-Ring dimensions? Mine broke and I threw them before measuring, would be realy nice if anyone can measure it.

[Mike Menci]

Nozzle ID = 6mm   - Holder Seal ID = 4.7mm 
Re-measure yourself  + add for sealing 0.3 mm

Mike could you also tell what is the thread diameter and size of this hexagon part?

Hi
9 mm is the hexagon part

[Marek T.]

Hi Mike, thx a lot!
I have made my machine (old Philips) to be compatible with Juki nozzles but thinking to change it into Samsung at some nearest mechanical changes - so the dimensions will be helpful. Juki Chinese copies are cheap but hopeless about their quality. Today version of Openpnp can treat many their problems (runout and pre-rotation) but it would be better have mechanics perfect and don't treat it with software.

btw what is the price of Samsung nozzle - original and copy?

[Mike Menci]

Hello Marek,

You can find price on nozzles here https://www.aliexpress.com/price/samsung-cp40-nozzle_price.html  

https://www.liteplacer.com/phpBB/viewtopic.php?f=11&t=175 ,.....

I have nearly finished my design of holder which can accommodate Juki and Samsung holder with nozzles... 
I need to do some tests soonest! 

You have Nema8 5mm hollow shaft on your P&P Marek ?

Cheers from Poland

Mike 

[Marek T.]

Hi Mike
My machine is old re-trofited Philips. I have converted original philips' holder (hard to find good used nozzles in these times) into holder for Juki nozzles. Fatal descission it was as copies' quality is more than fatal (runtimes) while original costs over $150. The luck that prior-to-vision is added to Openpno, without this these nozzles are not to use if the nozzle is not fixed with 3 screws and manualy calibrated (forget auto-changer or quick nozzles changing at all). So I'm interresting with Samsung as have still 3 machines to convert - however with old original system they are not precised but 2xtimes faster (no vision and faster DC servomotors driver) - so I'm still not sure if will do this for every 3.

Really waiting for your tests results about the runtimes of Samsung.

[Mike Menci]

Hello Marek, 

Please contact me to my private mail and I will explain and send you some photos of solution for holder. 

You can see the new Juki holder in this video: https://www.youtube.com/watch?v=7tKd8qeCu0Y

It has 7.0 mm diameter for Juki and Samsung 

[Mike Menci]

Here the view:

@Flitch:

I am having the same issue. (Where) did you find these O-Rings? Also, on some video, I saw someone apply grease to the nozzel holder. Does anyone know what sort of grease that is?

[Mike Menci]

you can use   Silicon grease for coffeemaker O-Rings or equivalent Silicon based grease.
For seal look for - OD 5.5 mm  x cross section 0.5mm ... (Darts seals ??) 

[darkridge]

Perfect. - Thank you!

[darkridge]

I found the correct o-rigns for the CP40 here. They are much smaller than the nozzle: od=4.5mm, id=3.5mm

[jbussmann]

I do not believe this is the correct o-ring, the cross-section to diameter ratio seems waaay off. But that shouldn't be surprising, because the cross-section is 1 mm wide, when I think it should be 0.5 mm wide as Mike suggested. Assuming " od=4.5mm, id=3.5mm" is supposed to be the o-ring dimensions, it is wrong because id = 2.5 mm.

I will take a picture of the correct one on a ruler, likely by Friday. Remind me if I should forget it. 

[tonyl...@gmail.com]

Here is a photo of the ones I have. They came as spares. 

[Mike Menci]

Hi Tony - thanks for picture.
Reverse eng- image to mm = ID= 3.8,  & OD = 5.2mm 

[bing l]

The manufacturer of the holder also does not have a drawing for this rubber ring, but look at the specifications on its outer packaging: 5 * 1 . This means that its OD is 5mm and thickness is 1mm, so its ID should be 5-2=3mm.

[Mike Menci]

Hello Bing - Have you tested this seals on CP40 holder with nozzles ? does this work OK - is it hard to get the nozzle on holder or easy slides on with a bit of lubrication? ? 

[bing l]

Its concentricity will definitely be better, the sealing will also be better, and loading and unloading will not require much force. But it is not easy to achieve automatic replacement because the nozzle and holder of CP40 are difficult to align.  

I haven't tested it, nor have I added any lubricating oil. But it is a rubber ring made for the  nozzle, and I assume it is OK. 

[jbussmann]

>  I haven't tested it.
That's all we need to know, the rest is just assumptions it seems.

This is the o-ring that was actually on my nozzle, not a spare that may or may not fit. According to my pixel math, id = 4.20mm, od = 5.30mm and cs = 0.55mm, please someone doublecheck! So if I had to choose, I would go with Mike's suggestion of 5.5x0.5mm. 

Anyone else with a contribution of an o-ring that is in use and not just a spare or something from the internet?

@Tony

Are you sure, this ring actually fits? It seems a bit too thick to me.

[tonyl...@gmail.com]

> Are you sure, this ring actually fits?

I haven't actually tried them, but they came with the holder as spares. So, I just assume they would be the correct ones.

[bing l]

[jbussmann]

I apologize for having doubted you. I could not have imagined, that these parts can differ by that much.
Unfortunately it makes this whole conversation pointless. It seems like these are only roughly similar and asking someone else for exact dimensions is about as useful as asking a random number generator. I will take extra care of my nozzles now, to hopefully never need spare parts.

[bing l]

Don't worry, if the rubber ring is damaged, let me know. You only need the shipping fee, and I can give it to you for free. I have customized this type of holder before, so the factory will provide it to me. 

We are currently only producing holders for CP45. Because I don't think this  CP40  rubber ring is a good design, and if you frequently replace the nozzle automatically, it will quickly  damaged.

[simpl...@tuta.io]

>> We are currently only producing holders for CP45

It's a pity that the CP45 holders that you have produced (somewhere?) are so unnecessarily long and that there is no normal, short version (with less weight, less runout) for the usual Nema8 hollowshaft motors.

[Mike Menci]

Shorter version you can find here! 

[Mike Menci]

CP40 - not CP45
