Vacuum pick and place head for 3-axis machine v0.0

thingiverse

Automate electronic assembly with this vacuum pick-and-place head design featuring a stepper-driven rotary head that accommodates Luer-Lock port for interchangeable needles and an "eyeball" style Webcam for optical placement. The vacuum is supplied via flex (fishpump) tubing to the head. Modify the camera mount if needed, and attach it along with a 3-axis machine mounting mechanism to the freeware CamBam-opened .cb files' plates. A test fit should be done before gluing anything down. Assemble the stepper motor, standoffs, top and bottom plate, larger and smaller pulleys, steel tubing, ball bearing, and Luer-Lock adapter, cutting the tubing to the desired height. Secure with adhesive, ensuring not to clog the air path. For optimal optical focus, set the needle depth an inch or two above the placement position. Sourcing motors may be challenging due to limited pulley/shaft diameters. Note that design files have been improved since the photos, so your assembly may differ slightly.
