Manual Pick and Place

picknplacePopulating a large surface mount PCB can take forever. [craftycoder] from Freeside Atlanta has built a great looking manual pick and place machine, removing the need for tweezers. No more will passives stick to your tweezers while you are trying to place them on your PCB!

We have seen a lot of pick and place machines in the past few years. What makes this one stand out is its simplicity and the no-nonsense build. This pick and place is built on an MDF platform, uses bearings from Amazon, standard 12 mm rails, and has a small camera for a close-up look at your part placement. Sure it is a manual method, but it beats painstakingly placing each part with tweezers. It would be interesting to see how much this entire build cost; we expect that it was not too expensive. See this thing in action in the video after the break.

We hope this project has inspired you to go out and make something cool! If so, let us know what you have made!

Update: Semi-automatic Pick and Place Goes Fully-Automatic


Way back in April we looked at an impressive Pick and Place machine project which wasn’t actually up and running yet. Well it looks like [Brian Dorey] has really put the pedal to the metal with this fall, posting nine project updates since September.

The previous system was working just fine but required quite a bit of user intervention to do the actual placing. So the first modifications toward the new goal centered around motorizing the gantry. There’s a lot of information on this, as well as the vacuum tweezer heads that were designed for the system. But for us it was exciting to read about the vibrating chip feeder. This uses the vibrating motor from an Xbox controller to jiggle the ICs from their tube packaging to a staging jig off the side of the build table. You can see a video of this after the break along with a demo of the entire machine at work.

[Brian] seems to favor the Xbox parts as he also used an Xbox live camera along with OpenCV to detect the parts and ensure they are lined up correctly. For the best results possible the parts need to be illuminated properly which is why he also built a rather interesting light ring using 144 red LEDs.

DIY Pick and Place just getting under way


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.

Semi-automatic pick and place machine


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!

An Inexpensive Manual Pick-and-Place Machine


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.

Pick and place that can’t pick or place… but it looks very promising

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.

DIY pick and place builds boards, is awesome

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.
