User, 18 Oct 2026: list the sensors the optical QC station uses.
- inline-optical-qc.md: sensor table in the station setup (4 cameras,
2 warp lasers, spindle encoder, 3 presence sensors and a through-beam,
6 cylinder position switches, door switch; thermal camera option and
laser line profiler alternative), with where each sits, what it
measures and the price signal.
- BOM: cylinder position switches were missing (6, SMC D-M9 class,
USD 25 to 60 each, estimate). Total now USD 16,264 to 33,184, still
16k to 33k; THB 0.54M to 1.10M.
User, 18 Oct 2026: for now one QC station for both machines; let the
records cool in a queue before testing them.
- inline-optical-qc.md "Where it sits": launch setup. Spindle stacks
from the Duplex system and the Classic, labelled at the press (press,
stamper set, first and last cycle), cool in FIFO racks (24 h accepted
practice, 8 h at the shortest, Stamper Discs; about one day of output,
2,800 to 3,100 records); the finishing operator feeds the station from
the cooled stacks. Gains: warp and centring measured on settled records
(the release value), one station instead of two, no Classic unloader
change, no warm-record sag or thermal camera. Cost: defects found hours
later, covered by the Duplex operator, per-cycle telemetry and an early
lane for the first records of each run and after stamper changes.
Record key from the stack label and stack position, checked against the
run-out stamper number. Capacity 10 to 12 a minute against 5 to 6:
one station to about two Duplex systems and two Classics. A station at
each press stays the later option. Cost table, open points, infeed row,
thermal camera note and the Newbilt question follow.
- Fleet calculator: the per-press stations and the release station are
gone; the finishing block shows the cooling racks with record stacks
and the one optical station by the corridor glass; tooltips, corridor
and conveyor texts; machine park back to its legend, finishing box
"cooling, QC, packing".
- quality-automation.md layer 1, digital-factory.md QC row,
process-flow.md stage 6, site-candidates.md block ground floor,
crane-workshop-tours.md tour stop 6.
- Investor render: infeed label "the operator sets each cooled record
down".
Checks: node --check; pw_bp_calc.py 0 fails; pw_iso_view_check.py OK;
info for every data-id at all presets, levels and rotations; GF nodes
2,414 at the full preset; zoomed shots in two rotations.
User, 18 Oct 2026: use real 40x40 profiles, make a render with text
pointing out the parts to show the investor; the ring lights looked
like they were floating.
- build_station.py: frame drawn from the real 8-slot 40 series section
(profile_shape: slots, centre bore, corner cavities; 40x80 with centre
cavity) and 24 cast angle brackets; top beams now butt between the
uprights; label-camera posts moved beside the cameras so both ring
lights clamp straight to them; top line-scan on a side post with
visible camera plate and light hangers; slide strips on carrier angles,
pulley axles, end-stop posts, presence-sensor brackets, backlight post,
cabinet on base crosses, chute on two supports and clear of the rail,
pneumatics rail, stack light on the back upright, touch screen on the
front end upright. A connectivity check at the end lists any part that
does not reach the floor through touching parts: none.
- render_annotated.py (FreeCAD): front three-quarter view, camera backed
off so nothing is clipped, no navigation cube or preselection, label
positions projected from the camera and checked with marker renders.
- annotate_render.py (Pillow): title, 16 labels in two columns, leaders
assigned so none cross -> inline-qc-station-annotated.png.
- render_station.py: same camera and preselection fixes; all six views
re-rendered.
- BOM: 32 m of 40x40 in 45 pieces; total still USD 16k to 33k.
- inline-optical-qc.md and README updated; .gitignore for the render
intermediates.
User, 18 Oct 2026: create a setup for the inline optical QC, an
aluminium extrusion frame with all sensors and a conveyor mounted to it.
- docs/equipment/inline-qc-station/: FreeCAD script (build_station.py)
and model (.FCStd) of one station, 1.9 x 0.65 x 1.5 m on 27 m of
40x40 and 3.8 m of 40x80 profile: rim-belt conveyor (two 6 mm PU round
belts under the unrecorded rim, open centre), label gate with top and
bottom colour cameras on the fly, inspection position with a lift and
rotate chuck (75 mm lift, expanding mandrel, belt-driven servo), top and
bottom 4k line-scans on opposite radii with coaxial, dark-field and
backlights, two warp lasers, optional thermal camera, light-tight black
tunnel with door switch, rodless-cylinder reject pusher with chute and
bin, outfeed stop, cabinet, PLC, NixOS edge PC, HMI, stack light.
- render_station.py renders six views (open and closed iso, front, plan,
inspection detail and elevation via clipped temporary documents).
- inline-qc-station-bom.csv: 32 lines with sources; USD 16k to 33k per
station without the thermal camera.
- inline-optical-qc.md: new section "The station setup" (flow table,
inspection zone, cycle ~5 to 6 s, control, BOM by group, open points);
cost table updated (two launch stations ~USD 50k to 105k, still inside
the metrology launch tier); Duplex/Classic flow now via the conveyor.
- README bullet and tree.
