It’s not totally fair to say that this project is just getting under way. But the truth is it neither picks nor places so there’s a long road still to travel. But we’re impressed with the demonstrations of what [Daniel Amesberger] has achieved thus far. Using the simplest of CNC mills he’s finished the frame and gantry for the device. You can see some of the parts on the left after going though an anodizing process that leaves them with that slick black finish.
The demo video shows off the device by driving it with a joystick. It’s fast, which gives us hope that this will rival some of the low-end commercial pick and place machines. He’s already been working on the software, which runs on a mini ITX form factor computer. This includes a gerber file interpreter and some computer vision for a visual check on part placement. He hasn’t gotten around to building the parts feeders but we’ll keep you updated as we hear back from him.

This is a fascinating take on building your own pick and place machine. It does an amazing job of automating the hardest parts of hand assembly, while relying on human dexterity to achieve the hardest parts of automation. It’s a semiautomatic pick and place machine driven by an Arduino and controlled by an Android tablet.
The machine is built in two parts. The portion in the upper left feeds components from reels and is fully automated. The portion on the lower right consists of a padded arm-rest which slides smoothly along two axes. A mechanical arm with multiple articulations is attached to the end, culminating in a tip connector for some vacuum tweezers. Right handers are the only ones who will find this convenient, but oh well. The clip after the break shows it in action. The assembly technician first selects the component from an icon on the Android tablet. The reel machine then dispenses that part, which is picked up by the vacuum tweezers using the left hand to switch the vacuum on and off again. If the part orientation needs to be rotated it can done using the jog wheel on the Android app. It smooth, quick, and best of all, clever!

When dealing with surface mount components, a manual pick-and-place machine is certainly a helpful device to have. Unfortunately, they can be quite expensive, so [Vassilis] came up with his own solution.
While commercial setups can cost upwards of a thousand dollars, this setup was made for less than a tenth of this cost. This one uses a simple setup of sliders and bearings available from a local hardware store. A cheap vacuum pen is used to lift the components, using an aquarium pump in reverse to generate suction. Finally, a USB microscope is used to make sure everything is placed in the correct position.
Plans are available on the site in DXF format, so you can build your own. The setup is reminiscent of a DIY CNC router, like this one that we featured a while ago. We could even see something like this serving a dual role with interchangeable heads for whatever you happen to be making that day!
Update: [Vassilis] published an video demonstration. See it after the break.

This sexy piece of CNC can really fly. It’s a pick and place machine which [Danh Trinh] has been working on. The thing is, so far it lacks the ability to move components at all. But the good news is the rest of the system seems to be there.
He posted a demo video of his progress so far which you can see embedded after the break. He starts of by showing off his computer vision software which he wrote in C#. The demonstration includes the view from the gantry-mounted camera, as well as the computer filtering which seems to accurately locate the solder pads and silk screen on the PCB. The second half of the video looks at the hardware seen above. It’s just executing some static code but the whine of those stepper motors is music to our ears. [Danh] reports that the movements of the needle that will eventually serve as the tip of the vacuum tweezer seem to be very accurate.
These home-built pick and place projects are quite a challenge, but we’ve seen a lot of really awesome work on them lately.

In what can probably be attributed to the pains of placing a lot of SMD components, [gravelrash] built his own home-made pick and place machine.
Instead of being frustrated with tweezers, stereo microscopes, and having an inordinate amount of concentration, [gravelrash] built a pick and place machine from a Chinese CNC router. The build doesn’t use automated feeders for its reels of parts. Instead,[gravelrash] picked up five manual feeders from eBay, allowing his pick and place to hold 25 different reels of components.
There is, of course, a vacuum pump for sucking up SMD parts and a two-axis gantry capable of moving components from reel to board. The software is Mach3, a program normally used with spinning cutters to mill away wood, metal and plastic. [gravelrash] replaced this motor with a few vacuum controlled needles to pick up, move, and drop components onto the board.
While the build may not be as fast as some other pick and place machines we’ve seen, it’s almost as fast as hand-placing components with the added bonus of not tearing your hair out over very tiny parts.
Tip ‘o the hat to [Alexander] for sending this one in.

For the last few months, [HeliumFrog] has been building a SCARA bot to serve as the basis for a pick and place machine. Somewhat amazingly, this is the first robot of its kind to be printed on a 3D printer.
A SCARA-type robot is an articulated arm perfectly suited for transferring components from tubes and reels to a PCB. [HeliumFrog] began his build with an arm with large gears in joints driven by stepper motors and toothed belts. The Z axis was originally driven with a lead screw, but after a thoughtful redesign that was changed over to another toothed belt.
We’ve seen our share of DIY pick and place machines, but most of those have been based on a traditional X/Y Cartesian frame. [HeliumFrog]’s SCARA bot should be – theoretically, at least – faster and more accurate while taking up a smaller footprint in the workshop.
[HeliumFrog] is more or less done with the basics of his build, and is now moving on to building a plastic extrusion tool head for his SCARA bot. Very cool, and should make this robot capable of self-reproduction for under £400 (~$600).
You can check out a video of this articulated arm bot after the break.
Thanks, [Kyle] for sending this one in.

It looks like Null Space Labs has a new pick and place machine. This immense repair job began when [Charliex] and [Gleep] found a JukiPlacemat 360 pick and place machine. The idea of having their very own pick and place machine proved intoxicating, possibly too much so because the didn’t return the machine when they found out it wasn’t working.
After a ton of work that involved adding a camera, [Charliex] and the rest of the builders at Null Space Labs finally have their own pick and place machine that works. This was a complete rebuild from the ground up. So many things didn’t work on the machine, they might have been better off building one from scratch. Aside from the massive effort that went into turning the shell of a machine into a working unit, we really have to commend everyone who worked on it.
The team added a nice GUI to control the machine. The guys have already run a successful test and ovened a few boards, so everything works as it should have at purchase. It’ll be great for making next year’s LayerOne conference badges.
