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.

Before:

After:

Assemble front-feeder-rail

Insert extrusion into assembly jig

  1. Insert a piece of 2020-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 2020-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 2020-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 2020-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 additional fasteners

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

  2. Install an additional M5x8-bolt and M5-t-nut into each corner-bracket

    • These bolts should be installed hand-tight (<0.2N/M)

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 `2020-alu-extrusion
  • Confirm the slit in the 2x3-idc-connector faces towards the left of the feeder-slot
  • The 2x installed corner-bracket pieces are flush to the 2020-alu-extrusion
  • The 2x installed corner-bracket pieces each have a spare M5x8-bolt and M5-t-nut installed into the unused holes
    • Total 2x M5x8-bolt and M5-t-nut

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 2020-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 2020-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 2020-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 2020-alu-extrusion

  6. Position a corner-bracket onto the back right side of the 2020-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 2020-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 2020-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 additional fasteners

  1. Pull the WIP rear-feeder-rail outward to remove it from feeder-rail-asm-jig
  2. Install 2x additional M5x8-bolt and M5-t-nut into each corner-bracket
    • These bolts should be installed hand-tight (<0.2N/M)

OQC

Perform the following quality control checks:

  • Feeder blades are installed sequentially from left to right
  • Wiggle the installed blades to ensure none are loose, retightening any if needed
  • The 2x installed corner-bracket pieces are flush to the 2020-alu-extrusion
  • Confirm the slit in the 2x3-idc-connector faces towards the left of the feeder-slot
  • The 4x installed corner-bracket pieces are flush to the 2020-alu-extrusion
  • The 4x installed corner-bracket pieces each have a spare M5x8-bolt and M5-t-nut installed into the unused holes
    • Total 4x M5x8-bolt and M5-t-nut

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