Tools of the trade / Re: SMT700 New vision based SMT machine from SMALLSMT
End of next month we release a new machine called VP-2800HP-CL64.

It has 64 CL feeder slots and 35x8mm push feeder. You can add 2 vibration feeder an North and one on South side.
We use new HD USB bootom cameras and double precision ball screw spindle.
Y axis has double linear guide line for high stablity.
The working area is bigger than 600x400mm.

We offer double with 6 slot nozzle changer and quad head version without nozzle changer.

Sorry no oursmt always talked about building a machine but I never saw.
We are currently building a mid range machine using yamaha feeder up to 120 x 8mm feeder on two sides.

But you should know each feeder line increase the machine costs by 150USD minimum.

Hi,
oursmt was the supplier of the SMT50 machine controller and software.
The software was not bad but the vision system was mostly useless so take care!
You need Chinese region settings to run the software.
I can help to get the software running.

Best regards
Michael

Also, certain 0805 caps are not reliably held by the nozzle. As the head moves the caps randomly move about from the vibration.

That's mostly a vibration problem you need to try on different speed to find the best result.
I had the same problem on my TM240 the vibration was up to 60% speed ok.

I don't know the Quihe software but I think you can define different speed for any part so try to decrease the speed for the caps.

That's the reason we have walk through tape winders.

Well ok I now had an opportunity to work with TVM802B for some time. Right now my biggest issue with the machine is the peeling mechanism. It sucks tremendously.

If you are buying this machine, plan on scrapping it and building a new peeling mechanism. The one they have is extremely unreliable. See, it depends on the friction in the roller to be set precisely. Too little, and it is not enough force to peel the cover tape. Too much, and it pulls through the carrier tape. The problem is, even if you adjust it to just perfect tension, it does not stay at that level. So once in a while the same tape might sometimes not peel, or sometimes pull too much.

in my recent run 2 out of 20 feeders could not be adjusted to reliable operation.

- your second TVM802B big problem is the vision system because of stray light problems!
- the third TVM802B problem is the feeder line if you use parts in plastic tapes because the drag needle precision is not good too ( this is a similar problem for TM240A too)

I used Neoden TM240 before and TVM802B is a copy of it and had problems with the spool too because the friction changes over time and if you start the diameter is low but after some tape is on the spool the diameter changes and friction changes too.

Our winder has no friction problems.
The only problem you might receive is a cut tape if the feeder line will not be used over a long time and the system is using the feeder on other lines for more than 1500 times.
In this case it is better to move the clear tape out of the winder and fix it on the case surface.

Hi,

we reached a new milestone the VP-2500HP spindle machine can place 0201 using vision alignment.

The video you find  Twitter http://http://www.twitter.com/smallsmt

You see 0402 and 0201 parts placed using vision alignment while machine was running on mid speed.
For the 0201 placement this was the first test I think it is possible to improve by tuning the speed parameters!
