Pick and Place machines are one of the double-edged swords of electronics.They build your boards fast, but if you don’t have everything setup perfectly, they’ll quickly make a mess. A pick and place can’t grab a resistor from a pile and place it – so far only humans can pull that one off. They need parts organized and oriented in reels or trays.
[Parker Dillmann] had to load some parts, but didn’t have a tray for them, so he 3D printed his own. [Parker] works at a small assembly house in Texas. He’s working on a top secret design which includes FFC connectors. Unfortunately, the connectors shipped in pick and place unfriendly tubes rather than reels. If he couldn’t find a tray, [Parker] would have to hand place those connectors as a second operation, which would increase the time to build each board and leave more chances for mistakes.
Rather than place each part by hand, [Parker] got in touch with his friend [Chris Kraft] who is something of a 3D printing guru. [Chris] confirmed that a 3D printed tray would be possible, though the PLA he prints with was not static safe. That was fine for the connectors, but [Parker] was hoping to save some tray space by putting his PSOC4 chips in the printed tray as well.
[Parker] used SketchUp to design a tray that would fit his Madell DP2006-2 pick and place. He left .15mm clearance around the parts – just enough to cover any inaccuracies during printing, but not enough to throw off parts placement. He sent the STL file over to [Chris] who used Simplify3D to a create a Gcode file. [Chris] printed the tray at .2 mm layer height on his MakerGear M2 printer, and the results looked great. Would they be good enough for the pick and place machine?
[Parker] received the printed trays in the mail and loaded them with parts. The pick and place had no problem finding and placing the connectors, making this job a huge success. [Parker] even left room for the PSOC4 chips.He plans to paint the tray with anti-static paint before giving them at try.
We really like this story – it’s a perfect example of how 3D printers can speed up processes in manufacturing. Now that the basic design is done, creating new trays is a snap. Nice work [Parker] and [Chris]!
