Please watch: "Mailbag: How to control a RGB Matrix 64x32 Display via ESP32" https://www.youtube.com/watch?v=vScZ5BasUIc --~-- I'm proud to present my first pnp platform prototype with the PNP plugin for eagle widget.

Here i describe the design of my first pnp-holder with all necessary informations about the tray and pocket Strategy. The Plugin managed automaticly the sort of components to his trays or pockets.

Here some additional informations:

Beta Test: http://chilipeppr.com/pcb

Plugin Code:

• http://github.com/xpix/widget-eagle-pickandplace

Philosophy:

• "simple as possible"
• no camera needed cuz accurate position of PNP Holder
• automaticly sortet components to Trays and pockets
• position on CNC in every case the same
• after homing you can use it

Platform: (Photo)

• milled in MDF, future Delron(POM) or Aluminium
• Holes for accurate position on whaste board
• Trays or Feeder numbered from 1 ... 8
• Pockets lettered from A-L
• Screw's to hold PCB in 1mm deep Pocket
• Tunnels for Probe wire's
• Calibrate block to find zero point

Strategy for Trays:

• Nozzle move the smd tape to next position https://youtu.be/CVlad7l9HvI?t=463
• Structure of a tray: http://www.token.com.tw/chip-resistor/smd-resistor1.htm
• 1. move nozzle to zero line (cambam) of Tray
• 2. move 1.75mm in X Direction
• 3. deep nozzle in a hole
• 4. move tape 4mm in Y direction
• 5. go back to smd position and get it

Strategy for Pockets:

• Nozzle move the smd pocket to pocket and get smd component https://youtu.be/CVlad7l9HvI?t=463 PNP Plugin:

• Parameters

  • only PNP gcode
    • send only this pnp gcode to machine
    • can use for pcb's made in china or osh park with stencil
  • packagesTrays, packagesPockets:
    • decide of this input which smd component are sorted to tray or pockets
    • user can input regular expressions (DIL\d+-SMD)
  • safetyHeight:
    • heighest point for nozzle to move without problems
    • Screw's height are ~10mm
  • RotationAxis:
    • axis on the second grbl controller to rotate the nozzle stepper for right direction
    • resistor in example
    • all roation values can see in trays/pockets table
  • Nozzle Outsidediameter
    • image: noki_nozzle.jpg
    • diameter on the smallest side of noozle
    • use for calculate the way to next cmp in tape
  • PNP Holder
    • load pnp holder data from json file
    • designs for more holder
    • horicontal, vertical Design

• Configure trays

  • Display table (eagle with mosfet)
  • automatic sort function to make the process very simple
  • explain Row's
  • The components were sorted according to their value
  • same value, then same tape or pocket
  • rotation are very important for bigger components in pockets, to know ... https://www.youtube.com/watch?v=1OrLeXnoQik
