redFrog Pick and Place machine - example of the pick and place process

This video demonstrates the process from solder paste application to picking and placing the SMD components to the final flowing of the solder. The picking and placing is done using the new redFrog pick and place machine.

I think that a kapton tape or similar is on top of SMD switches (maybe a wash protection) that would allow You to pick it with enough suction. At least, thats what I think...

Thank You for patiently putting videos of your machine.

@antadefector That's an interesting Idea.

[uazn88]

for the rotating A-Axis how did you create a zero or reference point for that?

[anajonesr]

@uazn88 I just make sure it is rotated the same way. I have a hose on the side of the nozzle that informs me visually of its orientation.

[uazn88]

what kind of vacuum are you using?

[anajonesr]

@uazn88 It is a standard smd vacuum that I purchased at mcmaster.com, but I am looking for a better alternative as this vacuum is higher priced than I would like to supply to others, and the suction is not sufficient in my opinion.

@uazn88 Mcmaster part number 5670A2

@KingNetherdrake the locations are set visually through camera siilar to most PnP machines. Thereafter, the machine will pick and place that board as many times as you want by itself. It takes the human imperfection out of the equation as long as the first one was done correctly.

@guruflorida Definitely, let's chat. Email me thought the contact us form on buildyourcnc and ask for Patrick. We can exchange emails addresses and discuss these ideas. Actually, the luer is a mechanical pencil tip. It's nice to have the ability to screw and unscrew at the tpi of this rather than the luer's very loose tpi. I did think about using a solenoid with a small diameter shaft to advance the tape using the holes. I may actually still do this.

Nice work. I wrote gcode subroutines to do PnP as well, my actual "place calls" ngc file looks almost exactly like yours. :) Yours looks more evolved though, more code if/then logic. I used a feed spike instead of the luer head. I made my spike and pickup head far enough apart it doesnt hit the part guide. We should chat, I have some ideas to share.
