Introduction

FirePick Delta is an open-source electronics manufacturing system, inspired by RepRap and powered by OpenPnP and FirePick's own Computer Vision software. We are taking the beginning steps towards a smart appliance that can manufacture electronic circuit boards in a home or office environment. Our machine is able to assemble open-source hardware boards like Arduino and Raspberry Pi accessories, and also has the capability to 3D print. It features an auto-tool changer that allows multiple plastic extruders, and/or multiple SMT vacuum nozzles. Other tools and applications will be available as our product matures.

Specifications

Intended Usage

  • Prototyping and small runs of PCB’s (under 100 per run). Not intended to be used for mass production.
  • Hobbyists, Makerspaces, high school and college students, entrepreneurs, small businesses.
  • Great for those with poor eyesight, shaky hands, or those that just don’t have the skills to solder on small SMT parts. We occasionally remind those that scoff at our project to check their privileges and remember that not everyone has guru SMT soldering skills or access to a full lab with hot air rework.

Cost

We would eventually like to cover three basic demographics:

  • Hacker and Developer Version: Open framework to go crazy with. Purchased with retail parts from US or foreign distributors. Est. Cost: ~$400-$500.
  • Maker / Student Version: Base machine in kit form for ~$300-400 is desired. That would not include any tools or feeders, or RasPi or camera. These things are modular and could be purchased at the time of sale or later on. Requires assembly, and support woudl be via internet forum / IRC / mailing list, etc.. The $300 figure is likely more of a BOM cost than final sale price with packaging, shipping, etc.
  • Professional version: For the tech startups, businesses, etc. Machine would likely retail for $5,000 to $10,000 for a fully assembled machine, with tech support and warranty, and all the other things that a business would look for, before buying a

Note that the Hackaday project is built around the Hacker / Developer version as a prototype, and we hope to offer the second (maker / student version) after the prototypes are built, and crowdfunding is secured. Version 3 ($5000-$10000) will be much later on, possibly 1-2 years from now.

Dimensions

  • Overall dimensions: 600mm H x 460mm W x 460mm D
  • Frame dimensions: 520mm H x 300mm W x 300mm D
  • Max PCB size / 3D print volume: 80mm H x 214mm W x 214mm D

Camera and Computer Vision

  • Camera: Raspberry Pi 5MP. 3.6mm focal length with f/2.9 aperture. Full control of shutter time, hardware flash, ISO, etc via custom FirePiCam software
  • Downward looking vision: Currently supported.
  • Upward looking vision: Planned feature. Will be implemented in the coming weeks. Our software chain fully supports it, it’s just a matter of making the 3d printed fixtures and trying it out.
  • Flying vision: Not yet, but it would be super cool. No timeline to speak of. Forget I even mentioned it.
  • Computer Vision Software: FireSight (high-level abstraction layer on top of OpenCV), via FireFUSE and FireREST
  • CV Operations implemented: absdiff, backgroundSubtractor, blur, calcHist, calcOffset, Canny, cvtColor, dft (Discrete Fourier Transform), dftSpectrum, drawKeypoints, drawRects, FireSight, HoleRecognizer, HoughCircles, imread, imwrite, matchTemplate, minAreaRect, MSER, morph, normalize, Points2Resolution, PSNR Compare, putText, QRDecode, resize, SimpleBlobDetector, stageImage, threshold, transparent, warpAffine, warpPerspective, warpRing

Software

  • OpenPnP - Is a project to create the plans, prototype and software for a completely Open Source SMT pick and place machine that anyone can afford. This is the GUI, and the program that handles all of the feeder, camera, and general machien setup, and also the job creation and processing.
  • FireSight - A high-level computer vision framework designed for Pick and Place machines, powered by OpenCV. No programming experience required - A pipeline of image operations is specified with a JSON structure. The results of the operations are returned as a JSON structure.
  • FireFUSE - FireFuse is theFUSE driver for all FirePick machines. FireFuse maps all hardware input/output functions for FirePick to individual files in the /dev/firefuse virtual file system. For example, the current camera view of the FirePick camera is presented as /dev/firefuse/cam.jpg. Presenting the camera output this way simplifies and generalizes access to the camera, since "it's just a file."
  • FireBOM - Similar to ThingDoc, FireBOM will auto-generate BOMs, documentation, real-time pricing and distributerer info, and keeps track of approved vendors and SMT part footprints.
  • FireMOTE - A web-based frontend for OpenPnP.
  • FireREST - FireREST is an open-sourceREST protocol for automated manufacturing. With FireREST, you can connect smart camera nodes, CNC application nodes, CNC machines and browser GUIs in a flexible, extensible manufacturing network. For the non-web gurus, this basically allows us to use raw http as a protocol between various systems in a robotics manufacturing network.
  • Arduino - Needs no introduction :) We will be designing an Arduino-compatible motion controller with modified RepRap Marlin firmware.
  • Raspberry Pi - Not 100% open-source, but their heart is in the right place. We plan on using the new Raspberry PI Compute Module, and the Raspberry Pi camera, to run OpenPnP and the other bits of software.
  • OpenCV - is alibrary of programming functions mainly aimed at real-timecomputer vision. Written in optimized C/C++. Thankfully, a lot of work has been done to get it working on the Raspberry Pi.
  • Linux - Too many crappy Pick and Place machines, only running on Teh Windows :-(
  • RepRap - An initiative to develop a self-replicating 3D printer.
  • Marlin firmware - The RepRap firmware is a mashup betweenSprinter,grbl and many original parts. It runs on an Arduino and handles the very timing-sensitive job of sending STEP and DIRECTION signals to the stepper motor drivers, controls temperature and extrusion. We'll be modifying it to double as a Pick and Place motion controller.
  • Greg's Wade Reloaded Extruder - Bulletproof extruder design
  • RAMPS v1.4 - Our custom board will be roughly based off the Ramps, but with the added stuff necessary for pick and place.
  • StepStick - Allegro A4988 16x microstepping motor driver
  • Slic3r - The world's best slicing program for 3d printing
  • Printrun - Pure Python 3d printing host software

Component size / Placement Accuracy

(Note many of these are not practical to place, until we get our feeders and vision 100% working)

  • Passives down to 0402
  • Diodes: SMC, SMB, SMA, SOD128, SOD80, SOD323, MicroMELF
  • QFN, DFN, QFP, SOIC, TSOP, BGA to ~0.4mm pitch
  • SOT23-3, SOT23-5, SOT23-6, SOT223, SOT89, SC70, DPAK, D2PAK
  • IC’s and large/wide components to ~50mm wide
  • Aluminum capacitors and tall components <= 15mm H

Modular Auto/Rapid Tool Changing System

  • Holds up to four (4) tools in the machine at the same time
  • System will recognize tools upon insertion. EEPROM in each tool keeps track of SMT nozzle size, and 3D printing parameters like thermistor tables, etc.
  • Tools are hot swappable
  • Average cost of materials per modular tool: $10 - $500, depending on tool.
  • Current tools offered: SMT vacuum nozzle, solder paste dispense, 3D Print hotend.
  • Future tools offered: Professional shot-meter style fluid dispense system for scientific laboratory or solder paste / glue dispense.Pen plotter, laser sensitizer (not big enough to cut stuff with), pogo-pin based flying-probe (for voltage testing, etc), Atmel AVR flying-probe programer. Hot air rework station for minor rework. Note that we intend for other members of the open-source community to help us bring these tools into existence, as the need arises.

Modular SMT Component Feeder System

  • ESD-safe via conductive ABS plastic 3D printing filament.
  • Average cost of materials per feeder: $5-10
  • Auto-recognized by OpenPnP via QR code labels affixed to feeders
  • Tape feeders: 8mm, 12mm, 16mm, 24mm, 32mm, 44mm. Drag-feed with (and without) cover-tape winding, and full-auto advancing version for 8mm
  • Tray feeders: Non-JEDEC. Holds a few small loose parts. Supports pause/reload prompts.
  • Tube feeders: NOTE: We’ve not started these yet, but see them as minimum risk. We started the tape parts first, since they’re more desirable. Will have a vibratory source (DC motor w/counterweight). Will be easy to customize and print custom tube feeders for weird non-standard chokes and coils, etc.

Build Instructions

Coming soon. In the meantime, our Github Wiki acts as an informal set of build instructions, as it contains an auto-generated stub for every part number that makes the mechanical assembly up. FPD wiki
