Update: Open Source Pick-and-place

February 8, 2011 by Mike Szczys 5 Comments

[Tim’s] been busy moving his pick-and-place build toward completion. We looked in on the first version of the vacuum head back in October. Since then he’s ditched the camera enclosure which allows for more light and better mounting. The tip has been replaced by one from a pair of vacuum tweezers, and the whole thing is now mounted on a diy CNC machine. The video after the break shows it picking up that IC and moving it around the table. Looks like the part rotation feature is very accurate.

He mentions that the CNC he’s using is quite slow. We hope he checks out this printable Delta robot; hardware that is often used with pick and place machines.

Automated Chip Burning

October 7, 2010 by Mike Szczys 28 Comments

[Alexsoulis] needed to burn the Arduino bootloader to a slew of ATmega328 chips. Instead of sitting there and plugged the chips into a programmer one at a time, he build a robotic microcontroller programmer.

It starts with the DIP package microcontrollers in a tube, with a servo motor to dispense them one-by-one. An arm swings over and picks up the chip with a fish pump powered vacuum tweezers similar to the pick-and-place head we saw recently. From there the chip is dropped into a ZIF socket and programmed by an Arduino. Once the process is complete it is moved to the side and the process repeats.

We’ve reported on using an Arduino as an AVR programmer but we’ve never actually done it ourselves (we use an AVR Dragon programmer). Take a look at the video after the break and let us know if you think the actual programming seems incredibly slow.

Open Source Pick-and-place

October 1, 2010 by Mike Szczys 16 Comments

This is a vacuum tweezers head for an open source pick-and-place. Those are the machines that professional printed circuit board manufacturers use to populate a circuit board with components before heading to the reflow oven. [Drmn4ea] built it with at-home rapid manufacturing in mind. The black orb on the left is a webcam for optical placement. The needle in the middle is an interchangeable vacuum-tool head. The motor on the right allows for different attachments to be swapped in automatically to suit a variety of parts.

This interfaces with a 3-axis CNC machine and should be easily compatible with a RepRap, Makerbot, or similar device. We wonder how he plans to handle reels of components, but this is a well-executed first step in the journey to a complete solution.

Want to see a professional pick-and-place at work? Check out one of SparkFun’s machines busy build a board after the break.

LEGO Pick And Place

Turn your volume down and take a look at the brick sorting robot in the video above. It’s built using LEGO and powered by four different NXT modules. It sorts differently colored bricks on the intake conveyor and places them on three output conveyors. The build is solid and was [Chris Shepherd’s] impetus for starting a blog. We appreciate the pneumatic tricks that he detailed in some of his earlier posts such as a compressor, pressure switch, and air tank system. His advice is “build, build, build” and that’s what you’d have to do to perfect a monster of this size and scope.

CNC Solder Paste/pick N Place

Just when I thought I’d seen most of the CNC mods out there, [Steve Ciciora] (who happens to be one of the driving forces behind the killacycle) sent in his diy solder paste dispenser *and* his diy pick and place machine. Both are extensions of his CNC taig mill. Hopefully [steve] will put up some more details of his mill mods.
