  1. Presents Sponsored by John Kennedy LoCoPnP

  2. Production Pick and Place Machine

  3. Introduction to PNP • Current PNP marketplace • $100k to upwards of a million dollars • Low cost ones • Problematic • Contain poorly documented software and hardware • Supported by just a single manufacture

  4. LocoBots’ PNP • Open source • Advantages in software design and maintenance • Hardware will be commercial off the shelf (COTS)

  5. Conceptual layout Diagonal View 1 Diagonal View 2 Side View Top View

  6. Components • Most open PNP machines made of components from Home Depot • Would not last in a production environment • Quality linear motion components upwards of $1000per axis • Sourced low cost components from China

  7. Components Cont. Ball Screws X and Y Bearing Rail

  8. Components Cont. • Aluminum Extrusion • Cut to length free • Strong, Light weight • Reconfigurable • Custom components made from aluminum plate stock • Cut and machined with basic tools

  9. Arduino 2560 Microcontroller

  10. Arduino 2560 Microcontroller (cont.) • Microcontroller supported by open source community for DIY projects similar to the PnP • 54 digital I/O pins which will support necessary operations • 16 analog inputs • 4 UARTs (hardware serial ports)

  11. Arduino 2560 Microcontroller (cont.) • Will use GRBL as a Gcode interpreter •  GRBL will be flashed on Arduino and a PC terminal window will be used to communicate simple G-code instructions to it • G-code is a language used to tell computerized machine tools how to move (i.e. G00 – rapid positioning, G01 – slow movement)

  12. Official PNP Specs • 500 estimated parts per hour • 800mm x 800mm working area • Optical feedback system for accurate part placement • 10 feeder reel stock capacity • 50 kg maximum weight • 920mm (w) x 944mm (d) x 480mm (h) • .05mm precision accuracy on X and Y axes

  13. Milestones • Research: 02/26 • Parts Acquired: 03/11 • Frame Assembly: 03/15 • Hardware Testing: 04/01 • System Integration: 04/16 • System Verification: 04/30

  14. Testing And Verification • Microcontroller and motor drivers testing • G-code interpreter (GRBL) • Correct operations from manual input • Motor testing • X and Y positional accuracy and repeatability • Z and A positional accuracy and repeatability • Head testing • Correct sensor feedback • Vacuum system and nose operations • Safety systems testing • Emergency shut-off switch

  15. Benchmarks • Operational X,Y,Z and A axes • Working vacuum pump • Ability for the head to select specific components and place anywhere on PCB • Design that is easy to modify or update in subsequent semesters by future engineering teams or hobbyists

  16. Project Budget

  17. Cost Analysis

  18. LoCo Bots PNP • Cost-effective functional product • Easy maintenance and ability to improve • Open source • Portable • Durable • Used in subsequent semesters
