Motorized SMD Reel Loader

thingiverse

I needed a simple way to refill the reels for my Pick and Place machine with bulk SMT parts, so I came up with this Motorized SMD Reel Loader. Features: * Small footprint. * Can handle reels with up to 7" diameter, easily expandable to other diameters. * Interchangeable shafts to handle 8mm, 12mm, and 16mm tape width. * Use two push buttons to control the direction of the reel. * Quickly helps refill your reel with bulk SMD components. Parts: You will need: 1 x Arduino Nano 1 x 28BYJ-48 5V 4 Phase DC Gear Stepper Motor+ ULN2003 Driver Board 2 x Tactile Switch 6x6x6mm 2 x 10K Resistor 1/4 W 1 x 15mm x 40mm DIY Prototype PCB 15 x 624ZZ 4mmx13mmx5mm Ball Bearing 1 x 20x20x160 mm profile 2 x 20x20x80 mm profile Phillips screws 2-28 x 3/8 BC-0206LPP 3mm x 16mm Socket Head Screws 4mm x 8mm Socket Head Screws 4mm x 16mm Socket Head Screws Wiring Notes: The following schematic shows the wiring of the Arduino Nano and the ULN2003 Driver Board with the 28BYJ-48 5V Stepper Motor. I used a Prototype PCB to create the user interface control board, with dimensions of 15mm x 40mm. I arranged the push buttons and 10K resistors as shown in the following picture. After all components were connected, I arranged everything inside the enclosure_box.stl (I used hot glue to secure the cables before installing the components on the box). I used the enclosure_arduino_clamp.stl to hold the Arduino Nano and secured the ULN2003 Driver Board with three Phillips screws (2-28 x 3/8 BC-0206LPP) as shown in the picture below. Notice the Arduino Nano's pins are facing up. Arduino Code: The code I used, to control the stepper motor using the ULN2003 and the Arduino Nano is on the file: "Motorized_SMD_Reel_Loader.ino" and can be customized to expand the functionality of the Motorized SMD Reel Loader.
