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.
