Key Questions to Ask When Ordering Samsung Smt Nozzle

Generally engaged in the SMT industry are know SMT nozzle is a key role of SMT machine components, with it to absorb and place SMT components, SMT nozzle on the market are various, according to the material divided into tungsten steel, diamond steel, ceramics, plastic steel, plastic, aluminum, iron, etc.. According to the shape of the round hole, square hole, V - shaped, according to the size is divided into a variety of. Now I will share with you the SMT nozzle and how to choose.

KF-SMT contains other products and information you need, so please check it out.

I. The function of SMT nozzle of the placement machine
The SMT nozzle is not only the key part of the SMT to attach and put the absorbed components, but also the background of the camera of the optical vision system when it takes pictures. It mainly USES vacuum adsorption to absorb the components, and USES air blowing to put the absorbed components on the coordinate position of the circuit board.
When the placement machine suction element, to achieve the ideal situation must ensure that the center of the element, the center of the suction nozzle and the spatial center of the obtained image should be coincident, and the adjustment of the optical vision system is actually to compensate for the deviation caused by this non-coincidence in the actual work.
Different mounting elements require different suction nozzles. Almost every suction nozzle has a reflected background, which is mainly to have a good background during image uptake, so as to ensure the accurate highlight of the target information during image processing. When the suction nozzle is extracted from the image, the suction nozzle is used as the background, so that the image contrast of components can be enhanced and more clearly visible.

II. SMT nozzle selection

1- Select the material of SMT nozzle:

A. Tungsten steel nozzle: tungsten steel nozzle strong, durable, but easy to white, trouble friends, or SMT new people can choose tungsten steel nozzle, white with an oily pen, can continue to use.

B. Ceramic suction nozzle: Ceramic suction nozzle will never be white, but it is very fragile and easy to break. Careful use can avoid or reduce the occurrence of fracture.

C. Diamond steel suction nozzle: strong, easy to use, never white, but very expensive, cost-effective.

D. Glue head suction nozzle: when the surface of the material is not smooth or sticky, it is suitable to choose the glue head suction nozzle, but the life of the glue head suction nozzle is not long. It is recommended to buy more glue head suction nozzle to spare, when the mouth is worn, you can directly change the glue head.

2-Select the size of SMT nozzle of the placement machine:
Standard specifications of the material, nozzle specifications are basically fixed, take Samsung SM as an example, material corresponding to CN065 suction nozzle, material corresponding to CN040 suction nozzle and so on, when some material is not big or small, strange shape, you need to customize the suction nozzle.

>>> I just bought a bag of new/old nozzles from Grove. I cant see any markings on them so I do not know which are which. Is there an easy way to tell?

p.s. I made some more convincing brass and PTFE inserts today, waiting on a few bits before trying the drilling operation again and ordered a few more nozzle blanks.

Thanks. Machine all plugged in and working my way through the manual. Tools in correct positions now helps. Uses Tool5 to calibrate head and comes up with error but I think it's at least using the correct tool to calibrate.

It does this apparently randomly, depending on the job - some jobs do it, some not. I suspect it may be related to maximum component size in the job, or some charactistic of a CDF used in the job.
Failing the test doesn't stop it proceeding, it's just annoying.

Getting the odd component too large fail but position  is decent when placement is completed

You probably worked this out, but this happens to me when lighting is different, or sometimes with a reel from a different supplier...

exit the place program,
Edit the CDF file for that component
set the "run time test" flag

then when you run the board, the machine will stop after imaging the component and allow you to tweak the values..

BTW "exit place program" just means exit from placing mode, not exiting RVPlace!

If only there was a button you could hit for "Stop placing and edit the CDF of the part you just falled to place.." - that would save sooo much time!

I had figured it would be something like that but had not changed it. It certainly needs a tweak. Thanks
>>> What resolution printer do you think is required for nozzles?

For my money, I think professional quality rather than than consumer ones. Also I think, the SLA/DLP processes rather than the SLS laser-sintered powder processes. But interesting question - the hard-to-print features are the end of the tool 1 and 6 nozzles and the lips of the o-ring nozzles - the rest is fairly low spec. The manufacturers are a bit sneaky with their resolution / accuracy specs so I'm finding testing is the only reliable way. It is possible that SLS plus clever manual finishing (drilling, and final turning) will work too. It is possible that DLP may need no finishing. SLA btw is used for jewelry masters and dental.

I'm also testing PTFE rather than brass inserts and also using 3D printer hot-end nozzles as the sharp bit. Sorry this is taking a while, but I think I'm getting there. This is the recent design I sent out (this is a render not a shot of the resulting printed part):

http://anagram.net/nuts/Versatronics/Nozzles/Tool%201%20with%200.5mm%20additions.PNG

... the idea is to turn off the extra 0.5mm addition to end up with a v. accurate nozzle end. If this design direction works out OK then it would also make custom nozzles v. easy to do.

A. UPDATE : I've had a pretty good price quoted from China, so I'll get a few in to try out..
If nothing else it will be a stop gap until complete ones are ready.
and it may be an easy way to get some of the bigger nozzles which will always be lower volume.
(fingers crossed)

A bit of lateral thinking ... It would be interesting to see what the dimensions of something like these is

https://www.alibaba.com/product-detail/SMT-Nozzle-Samsung-sm421-Nozzle-cn040_.html

in case they could be easily fitted to what remains of a versatronics nozzle when the end is broken off.

These tips for the CP45 are available to fit almost any component...


ps   

I found a drawing online and it looks like they will fit...   

Cut the samsung nozzle where the spring is
Machine off the pointy part of the versatronics nozzle (leaving the 10mm locating disc in place)

drill a hole in the end of the versatronics nozzle to fit the diameter of the samsung..

a nice tight fit or a dob of glue and bobs your uncle.



according to the drawing...  it is very, very, very close to being a perfect fit

between us we could buy enough to get them at a pretty low price..  and recondition all those old nozzles.

and it would be a lot easier to fit these to a 3d printed versatronics replica

I guess I will have to buy one at full price to try it out



Even better if a Chinese manufacturer can make cheaply to the original design ATM these are involving a bit of manual machining work, which isn't great for cost. And yeah, I think cut-off stainless dispensing needle / adapting the pointy bit of other nozzles or 3d printers may be interesting alternatives. I have the bits for adapting a 3D printer nozzle on the workbench, although as it stands it needs a longer 'receiving cup' but which I have printed up already. If anyone has an idea for a source of dispensing needle stock cut to length about ~8mm, please pipe up. BTW it would be easy to print up receptacles for the Samsung nozzles (or any other suitable 'pointy bits' of the right size) if the overall dimensions of the cut-off bit work out. BTW there's a tool height dimension in the rvdata.dat file - although as the existing nozzles are all 15mm, it's anyone's guess whether it works

FYI the current state of affairs, and I got the drilling to work late yesterday, at least for 0.6mm drills. New vs. original - the originals are the less mottled ones.
Not too bad but I hope these can be improved:




Let me know if anyone wants to try these out as I'm sure you all have more RVxS experience than me.

Alan Here is what was a broken original nozzle with a Samsung nozzle fitted to it..
the original needs a 3mm hole drilled in the centre,
The Samsung nozzle has to be cut through the middle
then is a push fit in the 3mm hole....!

it works well, except....  the nozzle is about 1mm longer than the original.



If the original plastic locating boss was removed, it would probably work just fine..
as the boss on the samsung nozzle is within 0.2mm the same diameter... 

but that will have to wait until after I have tested Alan's nozzles.  ( which look good )
