Feeder Rail (Front and Rear)

Introduction

The purpose of these work instructions is to cover the assembly process for the LumenPnP's front and rear feeder rail. These rails are used by the LumenPnP to space its two y-gantry assemblies apart. These rails also allow for auto feeders to be installed onto the LumenPnP and electronically connected via the 50x mounted feeder slots.

Assemble feeder-blade-set

If you have not already done so, go to this page for instructions on preparing a feeder-blade-set for use in the LumenPnP Feeder Rails

Assemble front-feeder-rail

Insert extrusion into assembly jig

  1. Insert a piece of alu-extrusion into the feeder-rail-asm-jig

Install corner brackets

  1. Loosely install a M5x8-bolt and M5-t-nut onto 2x corner-bracket
  2. Position a corner-bracket onto the front left side of the alu-extrusion previously placed in the feeder-rail-asm-jig
  3. Press the corner-bracket downward and inward (towards the sidewall of the jig) while tightening the M5x8-bolt to 0.7N/M
  4. Repeat the previous two steps on the opposite side of alu-extrusion
  5. Confirm the WIP front-feeder-rail matches the image below

Install feeder blades

  1. Collect a feeder-blade-set from inventory

  2. Install Feeder Slot Blade (#1 - #12) onto the front left side of the alu-extrusion

    • Press the blade assembly downward and inward (towards the sidewall of the jig) while tightening the 5x M5x10-bolt to 0.7N/M, starting with the center screw and tighening the screws in pairs moving outwards

  3. Repeat the two previous steps to install Feeder Slot Blade (#13 - #25)

Install blade-jumper-harness

  1. Pull the WIP front-feeder-rail outward to remove it from feeder-rail-asm-jig

  2. Connect blade-jumper-harness to the two PH-connector located between Feeder Slot Blade (#1 - #12) and Feeder Slot Blade (#13 - #25)

OQC

Perform the following quality control checks:

  • Feeder blades are installed sequentially from left to right
  • Wiggle the installed blades to ensure no screws are loose, retightening any if needed
  • Ensure the print is free of defects and fits flush to `alu-extrusion
  • The 2x installed corner-bracket pieces are flush to the alu-extrusion
  • Confirm blade-jumper-harness is installed into the blades

If all checks pass, bring the completed front-feeder-rail to the shelf for peer-review and pack-out.

Assemble rear-feeder-rail

This section of the work instruction will be a little less detailed than the above section on front-feeder-rail as it builds off the same process.

Insert extrusion into assembly jig

  1. Insert a piece of alu-extrusion into the feeder-rail-asm-jig

Install corner brackets

  1. Loosely install a M5x8-bolt and M5-t-nut onto 4x corner-bracket
  2. Position a corner-bracket onto the front left side of the alu-extrusion
  3. Press the corner-bracket downward and inward (towards the sidewall of the jig) while tightening the M5x8-bolt to 0.7N/M
  4. Repeat the previous two steps on the opposite side of alu-extrusion
  5. Confirm the WIP rear-feeder-rail matches the image below before proceeding to install 2x corner-bracket on the backside of the alu-extrusion

  6. Position a corner-bracket onto the back right side of the alu-extrusion

  7. Press the corner-bracket downward and inward (towards the sidewall of the jig) while tightening the M5x8-bolt to 0.7N/M

  8. Repeat the previous two steps to install a corner-bracket onto the back left side of alu-extrusion
  9. Confirm the WIP rear-feeder-rail matches the image below

Install feeder blades

  1. Install Feeder Slot Blade (#26 - #37) onto the left side of alu-extrusion

    • Press the blade downward and inward (towards the sidewall of the jig) while tightening the 5x M5x10-bolt to 0.7N/M, starting with the center screw and tighening the screws in pairs moving outwards

  2. Repeat the two previous steps to install Feeder Slot Blade (#38 - #50)

Install blade-jumper-harness

  1. Pull the WIP rear-feeder-rail outward to remove it from feeder-rail-asm-jig

  2. Connect blade-jumper-harness to the two PH-connector located between Feeder Slot Blade (#26 - #37) and Feeder Slot Blade (#38 - #50)
