I needed an easy (and fun) way to refill the Reels for my Pick and Place machine with the bulk SMT parts I buy, so I come up with this Motorized SMD Reel Loader.

Features

Small footprint.

Can handle Reels with up to 7" diameter, easily expandable to handle other diameters.

Interchangeable shafts to handle 8mm, 12mm and 16mm Tape Width.

Use two push buttons to control the direction of the Reel.

Can quickle help refeel 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 use the Prototype PCB to create the user interface control board, with the dimensions of 15mm x 40mm, then arrange the push buttons and the 10K resistors as shown on the following picture.

After all compoents are connected, I arrange everithing in side the enclosure_box.stl, (I use hot glue to secure the cables before installing the components on the box) and use the enclosure_arduino_clamp.stl to hold the Arduino Nano and use three Phillips screws (2-28 x 3/8 BC-0206LPP) to secure the ULN2003 Driver Board as shon on the picture below, notice the Arduino Nano's pins are facing up.

Arduino Code

The code I use, to control the steper motor using the ULN2003 and the Arduino Nano is on the file: "Motorized_SMD_Reel_Loader.ino" and can be cutomized to expand the functionality of the Motorized SMD Reel Loader.
