how the hell does some one build this in there home wow there brains must be amazing.

I thought the same

@@nicholasantony7665 how do people design them in the first place? Or 3d printers and cnc machines? But yeah, its incredible stuff!

@@LittleRainGames It is quite simple. The biggest problem is control of machine like this. Almost every part of this machine is easily purchasable, and even cheap - stepper motors, transmission, belts, controllers for motors, guides...

he live sin a machine shop,! thats logical

How much did it cost to make it?

sir,,,its good to hear that u made thousands of pcb's,,,,,but kindly tell us the price of the machine,,,,we r from poor country,,,,,

Who is Volker 🤔

очень круто! ;-) yep, very cool pnp machine!

+Mike Endersbe Could you explain what a screen printer is?

Solder paste printing process involves a metal screen that you lay on top of the PCB, with tiny cutouts at just the right locations, then the solder paste is uniformly applied to the area which then fills-in the holes where the solder must go on the board. So instead of the 1st process shown in video where the paste at each solder joint is applied individually, all solder joints would get the paste in one step with the printing process thereby reducing the cycle time drastically and boosting your production output :).

Stein-Erik Dahle There will be some more videos in the future. I am currently very busy with other stuff. So please be patient.

Im looking forward to that!

You are fully right - Another thing on the software ToDo list :-)

also, did you ever sort out the moves for bringing a part over the alignment camera? seems like there were some easy wins there: combine the separate x and y moves into one diagonal move, and run that initial part rotation during the move instead of while stationary over the camera before it activates. i'm also curious about the pauses between each move in general, is that to prevent vibrations from from one move messing with the subsequent move? it seems like most of the Z move (aside from the bottom few mm) would be pretty insensitive to vibration so i wonder if it's necessary between xy and z moves. i'd be curious if you could even start the z move slightly before the xy move ends, as long as xy is has come to a stop for the last [part height + max part height + some margin] of z travel (and leave enough time for any vibrations to dissipate before contact). i imagine that latter part would be a fair bit harder to implement though!

@@spambot7110 There's actually a reason why it doesn't rotate while moving with bigger parts. They are much more likely to fall off. Notice also how the speed of the motors is reduced when carrying larger parts. I think before inspection it's intentionally avoiding going over the PCB in case it does fall off or fail inspection. If it fell off during movement over the PCB that could knock other parts out of alignment and be a mess for the operator.

i wonder how suction head held at all...

Actually it does not run that slow... most pro machines only have ability to pick 10 components at once (10 nozzles) and also cameras directly on head to align components while travelling, but travel speed can be sped up only until physics permit it - weight of component, suction of nozzle etc makes a huge part in it.

Which is faster and more accurate? This one is a home-made one, the regular P&P machines can work much faster. Plus, you won't need the laser-cut stencils, solder paste locations can be easily exported from the board files. Plus, you don't need humans ;D to some extent.

Ah, I thought that machine was working at it's max speed. I suppose with the added ability to place, it's better than placing by hand. I both screen and place by hand, it is exhausting when you have to make more than 6 panels of something.

@@SirBrittanicvs Stencils are better than this method for volume. However, one off this method is very much more preferable and very much cheaper. I have read in other comments that he should use a sort routine of all the XY coordinates to greatly speed up the process instead of processing the corrdinates in order of their creation by the program. In addition, turning the sensor on before the arm arrives and putting in a small delay once it arrives would help speed up alignment. Finally, I read that staggering the solder blobs would prevent bridging. All in all, this is a fantastic device! Leave it to the internet to come up with even more radical solutions to making it faster. On the stencil front, you can actually make automatic stencils...I thought of a way using an inkjet printer. You take the pad layer, export it to some software which inverts the image so most of it is black except the pad. Then you print it out onto an aluminum sheet. Then, you dunk it in acid. The exposed metal will etch away leaving a perfect pad stencil. Then you use the vacuum assembly to place the stencil over the board, and then use the standard drag method to get all the pads. This would of course, eliminate the resolution issue entirely, but is considerably more complicated to incorporate into an automated procedure. However, if both processes were managed by a master controller routine, with the separate operations modularized and performed in sequential order, indicating to the master controller that the process was complete, then the next phase, placement, could begin. Like a 4 bit (00 01 10 11) signal, which would only take up 2 GPIO pins to indicate to the master controller what cycle to do next. Initialize, stencil, placement, and one more for something I probably didn't consider. IDK what setup he has though so...

But why? I would like to understand what problem he faced. About the printer, he is "printing" the pad with tin paste instead of ink (I'm not talking about pieces placement)

nope, you can still use the same coordinate method, you just need to order the point in a different way; by one axis, and by by the other with a stable sort algorithm.

Mauro lesto I saw the same thing, I used the Morton distance to order the tasks on my milling machine recently, the problem being a traveling salesman, you need some heuristic (and that was the easiest one to develop to be honest). I would also try to fly the components in a succession of cornu arcs to avoid stoping when changing direction.

nraynaud1​​ i'm NOT talking about component but about applying *solder paste* for component i can understand its difficulty IceTurf​​ if you disagree can you tell me witch algorithm would you use and why?

yep, me too

Very wonderful . How much it cost And what is the model

I saw that too . I was like "ah now I understand why he made this machine" lol

Its just a camera

Very nice. Our compliments to Volker.

Hi Bob, a great idea. I will try that. The dot size limitation is currently limited by the ball size of the solder paste. I will try and get paste with smaller dots some day.

VBsProjects Just have it move a little higher before moving to the next pad. Nice work.

+VBsProjects a fux pre tratament on board dont fix theses bridges? Yu know fux is nerver too much :P

Lol.

anyway - it is excellent results! i'm just dreaming about making some home p'n'p machine...
