Assembly
Tools Needed
- Needle Nose Pliers
- Screw-driver set
- Allen key set
I. Frame
Base Frame
- Place down one
12" single rail
and one12" double rail
both on their 1" x 12" side. - In between the two rail, place two
6" single rail
on either end so the four rails form a 9" x 12" rectangle. - Prepare Screws for Tank Stands
- Loosely screw together 4 sets of
cap screws
andT-nuts
. - Slide 2 assembled screws onto the
12" single rails
and 2 onto the12" double rails
. - Make sure the screws face the inside of the frame-rectangle.
- Loosely screw together 4 sets of
- Attach the frames together using 8
cap screws
, 8T-nuts
, and 4single brackets
. - Attach a
bumper
below each corner (4 total).
Vertical Frame
- Orient the rectangular framing such that the
12" double rail
is on the right. - Behind the farther
6" single rail
, center one24" double rail
oriented vertically with a 2" side flush with the frame. - Attach the
24" double rail
to the base frame using 4cap screws
, 4T-nuts
, and adouble bracket
.
II. Syringe Pump
Syringe Holders
- Attach a
cap screw
andT-nut
to each screw hole of the 3-D printed syringe pump mechanisms.
When attaching the screws, leave room for the pieces to slide onto the framing.
TheT-nut
should be on the flat side of the print. - Slide the
syringe hub holder
onto the24" double rail
oriented like an “L”. - Tighten the screws when the holder is 5.5" above the rectangular frame.
- Slide the
flange holder
onto the24" double rail
oriented like an upside-down “L”. - Tighten the screws when the
flange holder
and thesyringe hub holder
can fit yoursyringe
.
Ours is approximately 5.25" apart at their farthest edges.
Syringe Displacer
- Place the
steel hex nut
into thesyringe displacer's
hexagonal slot and slide it into place.
The threaded part of thenut
should align with the circular cutout on thedisplacer
. - Place the
linear bearing
into thesyringe displacer's
circular hole.
You want the bearing to be flush with the syringe cutout. - Spin the
threaded rod
into thesteel hex nut
until thesyringe displacer
is around the middle of thethreaded rod
. - Slide one
motion shaft
into thelinear bearing
. - Place the
motion shaft
and thethreaded rod
into their corresponding hole in theflange holder
.
Themotion shaft
is closer to the frame, thethreaded rod
is farther.
Syringe Motor
- Attach the 8mm end of the
rigid coupler
to the top of thethreaded rod
using twoM4 set screws
. - Attach the
syringe motor
to thesyringe motor mount
using 4M3 screws
. The wire should face left or right. - Slide the
syringe motor mount
onto the framing so the motor shaft fits into therigid coupler
.
Also, themotion shaft
fits intosyringe motor mount's
cylindrical extrusion. - Secure the motor to the coupler with 2
M4 set screws
. - Tighten the mount’s
cap screws
.
III. Baths
Assemble Rod Posts
- Place a
nylon hex nut
into the 3D printedaxel's
hexagonal slot. - Slide the
axel
into apost
and secure with anylon screw
. - Snap two
plastic ball bearings
onto theaxle
with the bearings facing out. Eventually, you want the metal bearings to be facing away from the baths. - Repeat steps 1-3 two more times (3 assembled rod posts total).
Attach Passive Roller Posts
Note: orient all the rod posts so that the bearings’ metal parts face out.
- Orient the frame so that the
24" double rail
is furthest from you. - On the
12" single rail
, place one assembledpost
with its bottom edge 2.25" from the bottom of the frame. - Repeat step 2 with
12" double rail's
left rail. - Attach both
posts
to theframe
with 4cap screws
and 4T-nuts
.
Attach Motorized Roller Posts
- On the
12" single rail
, place anotherpost
with its top edge 3.25" from the top of the frame. - Attach the
roller motor
to the 3D printedroller motor mount
with fourM3 screws
. The wire should face down. - On the
12" double rail
’s right half, place theroller motor mount
with its bottom edge 2.25" from the bottom of the frame. The wire faces away from the frame. - Attach the
roller motor mount
andpost
to the frame with 4cap screws
and 4T-nuts
.
Attach Tanks
Note: tank stands are attached on the inside of the frame in an upside down “L” shape
- Beneath a passive rod
post
, attach awide tank stand
using the two pre-attached screws farther from you. - Repeat step 1 for the other passive rod
post
. - Beneath the motorized rod
post
, attach anarrow tank stand
using the remaining pre-attached screws. - Repeat step 3 for the
roller motor mount
. - Place the
coagulation bath
on thewide tank stand
. - Place the
wash bath
on thenarrow tank stand
.
IV. Collectors
Assemble Passive Roller
- Slide one
roller
onto onemotion shaft
. - Slide a
shaft sleeve
on either side of theroller
. - Place the
roller
onto the passive rod posts, aligning theshaft sleeves
with theplastic ball bearings
.
Assemble Motorized Roller
- Slide the second
roller
onto the othermotion shaft
. - Slide a
shaft sleeve
on only one end of themotion shaft
. - On the other end, attach the 8mm side of the
flexible coupler
using twoM4 set screws
. - Attach the 5mm end of the
flexible coupler
to theroller motor
using twoM4 set screws
. - Align the
shaft sleeve
with theplastic ball bearings
on the other side.
Secure Rollers
- Position the
rollers
in the middle of the tanks. - Slide an
M2 nut
into each slot of each roller. - Secure the
rollers
to themotion shafts
withM2 screws
(4 nuts and 4 screws total).
V. Controller Box
Attach PCB
- Place the prepared PCB inside the 3D printed
controller box
, ensure the connectors match the outlets on the box. - Secure the PCB with 4
M3 screws
.
Assemble Controller Panel
- Remove the threaded ring from the
pushbutton
, insert thepushbutton
into the dedicated slot on the controller top panel. - Secure the
pushbutton
with the threaded ring. - Remove the nut from the
potentiometer
, insert thepotentiometer
into the dedicated slot on the controller top panel. - Secure the
potentiometer
with the nut using a plier. - Place the
display
into the dedicated slot on the controller top panel. - Secure the
display
with 4M2 screws
with nuts.
Connecting Wires
- Plug the
pushbutton cable
into theBTN_DIR
connector on the PCB. - Plug the
potentiometer cable
into thePOT1
connector on the PCB. - Plug the
display cable
into theOLED
connector on the PCB. - Plug the
pedal cable
into thePEDAL
connector on the PCB
Close the Controller Panel
- Use 4
M2 screws
to attach thecontroller panel
onto the controller box
