Staging Plate
This set of work instructions is out of date!
What's shown here is for v3.0.5
of the LumenPnP. Instructions for the latest version of Staging Plate
still need to be written for LumenPnP v3.1.#.
The biggest differences not shown are:
1) Introduction of colored tubing
2) Introduction of an easily removable nozzle-rack
Please note - the QC Checklist is up to date.
Subassembly Prep
Install hardware into 3D printed components
- Use an arbor press to insert the given quantities of
M3-hex-nut
into the following parts: - 2x for
y-coupler-bracket
- 3x
valve-mount
-
4x for
bottom-camera mount
Note
Be sure to change the arbor press tip for the different prints as needed.
-
Install 2x M3-square-nut pieces into each of the 2x vacuum-pump-mount (2x per pcs) with an arbor press
-
Install a ground-down metal pin tip in the arbor press chuck to help push these nuts to the proper installation depth
-
Confirm that the M3 threads are fully accessible
-
Install 4x rubber-band onto 2x vacuum-pump-mount (2x per pcs)
Preparing pneumatics system
Cutting tubing to length
- Produce the required QTY of each of the pneumatic tubing
- SEE ALIGNI for lengths
Attaching vacuum-pump cables
Prepare the following assemblies:
ASM-0004-01
[Left Head Wired Vacuum Pump Assembly]ASM-0052-01
[Right Head Wired Vacuum Pump]
Build the assemblies per SOP-0002 and be sure to follow recent updates to Step 2
for the new labeling process:
- Place and shrink a heat shrink tubing label onto
CHA-0011-00
that says “P2”- Position the new “P2” label so that it covers over the original “P1” label, with the text orientation matching the image below
- Set completed assemblies aside for later use
Labeling solenoid-valve cables
- Use
FBO-0022-00
[Epson LABELWORKS 224VSLPX Tape] to labelPNU-0004-00
[solenoid-valve] cables the following way: - Half of the solenoid-valve units in a given production batch must be labeled “MOS 2” for left head pneumatics (LH/P1)
- Half of the solenoid-valve units in a given production batch must be labeled “MOS 4” for right head pneumatics (RH/P2)
- Attach the labels in the near the end of the cable connector as shown below -
Note
Templates for these label can be found on the Docker workstation PC’s Documents
folder
Assembling left head / right read pneumatic systems
Connect all relevant pneumatic tubes to their respective values, pumps, and couplers by referencing the images shown below
Left Head Pneumatic System (P1)
Right Head Pneumatic System (P2)
Connect the left and right pneumatic systems together
Connect these two separate pneumatic systems together by installing y-coupler-bracket
and valve-mount
between the two halves
- Attach each solenoid-valve to
valve-mount
with 2xM3x8
bolts - Make sure that the valves are installed in the correct location by matching them up with the embedded text found on
valve-mount
- After completing this step, set the completed pneumatics system aside for later use
Prepare additional components
Removing punch-out from PCB-0003
- Remove the punch-out from center of
PCB-0003
with flush cutters
- Clean up hole with a razor blade after punch-out has been removed
- Clean both sides of
PCB-0003
with an IPA-soaked shop rag
Focus the bottom-camera
Use the bottom-camera-focus-jig
to pre-focus bottom-camera
- Loosen the set screw on the side of the lens, this will let the lens focal-point be adjusted
- Be careful not to loosen it too much or the screw may fall out and get lost!
- Remove the lens cap from bottom-camera
- Rotate the camera lens back and forth to loosen any glue
- Hold the PCB in one hand while twisting the lens body with your other hand
- Don't be afraid to use a few pounds of force if needed
- Install the
bottom-camera
fully into thebottom-camera-focus-jig
- Put the JST-side of
bottom-camera
into the jig first - Connect the JST-side of the USB cable into the bottom-camera PCB
- Connect the USB cable on
bottom-camera-focus-jig
to a computer and open its native camera viewing application - Use Photobooth if on Mac OSX or Cheese if on Linux
- Confirm that the camera feed is running in 720p, sometimes it can launch in 360p or 480p
- Within the camera viewing application, change the selected camera to
PnP Bottom
to view the camera feed of the bottom-camera
!!! warning "If the listed camera is something other than PnP Bottom
, the device may either be incorrectly programmed or mixed up with a top-camera module"
Please take this as an opportunity to double-check the device name even if the computer switched to the correct camera feed automatically.
- Rotate the camera lens until the live viewport shows the datum board as focused as possible
- Before and after lens focusing:
- Once the camera is focused, tighten the set screw to lock in the focus adjustment
- Put a blue dot on the camera PCB with a sharpie to denote that the camera has passed testing
- Remove the
bottom-camera
from thebottom-camera-focus-jig
and immediately replace the lens cap - Return the
bottom-camera
to the red esd-safe bag
Creating bottom-camera-assembly
- Attach
bottom-camera
andbottom-camera-cover
tobottom-camera-mount
with 4x M2.5x8 bolts
- Confirm
bottom-camera
's JST connector is next to the zip-tie cable strain relief feature, as indicated below:
- Clean
bottom-light-mount
print by removing any loose stringy plastic with a heat gun and/or razer blade (as needed) - Install
bottom-ring-light
intobottom-light-mount
Assemble nozzle-rack
- Install all 6 different nozzles onto the
nozzle-rack
, ensuring that each nozzle can pop in and out relatively easily
- Place a rubber-band around the
nozzle-rack
after each nozzles has been installed - This is to keep them from falling off the
staging-plate
in transit to the customer
-
Insert 2x
m3-hex-head-bolt
into the left and right outermost slots on thenozzle-rack
!!!note - This photo is out of date, it should show 2x M3-hex-head-bolt instead of nuts - These slots have a loose fit so use care to avoid losing a bolt during handling
Final Assembly

Installing the motherboard
- Install 4 M3x25mm standoffs onto
staging-plate
- Place in positions shown below with 4x M3x10 bolts
- Install
bottom-ring-light
cable - This cable should pass through the bottom and top right standoffs on its way to
bottom-ring-light
- Make sure that
UL
label is on the side of the cable closer to themotherboard
- Drill out the M3 mounting holes in
mobo-bottom-cover
to an M3 bolt has generious clearence - Pass the RH/LH vacuum lines and
up-light-harness
through themobo-bottom-cover
andmotherboard
- Take care to avoid having the vacuum lines twist around each other between the
y-coupler
pieces andmobo-bottom-cover
- Connect the vacuum lines and cable into the
motherboard
where appropriate - LH --> VAC1 on
motherboard
- RH --> VAC2 on
motherboard
- Bolt
motherboard
to standoffs in 2 initial locations with M3x10 bolts- bottom left and top right - Inspect both vacuum lines to see if either appears pinched on the backside of the
motherboard
- If either vacuum line appears pinched, push the line into the
motherboard
to increase the slack in the line betweenmobo-bottom-cover
and the respectivey-coupler
-
Connect all pump and valves cables into the motherboard while matching the cable labels to the
motherboard
connector labels -
Avoid needless twisting of the cabling
-
Install
mobo-top-cover
-
Bolt
mobo-top-cover
to the top left and bottom right standoffs with 2x M3x30 bolts -
Hand tight is OK as the customers need to be able to remove this piece during machine setup
- Slide the mobo QC receipt between mobo-bottom-cover and staging-plate after the
mobo-top-cover
is attached
Install datum-board and datum-board-mount
- Use four M3x16mm screws and four M3 nuts to secure the
datum-board
anddatum-board-mount
to thestaging-plate
on the rear of thebottom-camera
, through holes: B18, A19, A21, B22. - Use a 2.5mm hex wrench and a 5.5mm (6mm if 5.5mm is unavailable) socket wrench to tighten these M3x16mm screws
- The fisheye calibration pattern should be facing down, and the gold grid lines and fiducial in the center of the Opulo logo facing upwards
Attach Machine Serial # Label
- Install a unique Machine Serial # sticker onto the bottom of the
staging-plate
!!!note
- The up-light-harness
shown above is installed backwards
- The up-light-harness
label should be on the motherboard
side
- The side plugged into bottom-ring-light
should be unlabled
Performing cable management
- Clamp cables in the locations shown below with 6x
peek-cable-clamps
, 6xm3-hex-nut
, and 6xm3x14
bolts
QC Checklist
Run the staging plate assembly through the QC inspection form found here:
https://docs.google.com/forms/d/e/1FAIpQLSf1HXndxFzhRyJsBtHUMHoJEiU_ig9z8cUJpGCH4vcM8OR5mQ/viewform
Note
- The QC inspection form will ask you if the bottom-camera was correctly focused with the orange version of the
bottom-camera-focus-jig
- Use this jig in the same way the blue one is operated, while leaving the camera installed on the staging-plate
If the camera is out of focus, remove it from the assembly and repeat bottom-camera focusing.
