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.
User, 17 Oct 2026: research on the inline QC equipment, which devices
can be used for the optical check.
- New docs/equipment/inline-optical-qc.md: defect-by-defect table with
the optical signature, device and limit (IEC 98 / DIN 45547 hole and
eccentricity, Stamper Discs targets, Mobineko warp limits), precedents
(no vinyl product; Dr. Schenk ISM CD scanner as template; Basler/Xiris;
PRP AQA 2023; CTU thesis), a station design (centring turntable, 4k
line-scan per side with dark-field, bright-field and transmitted light,
colour label camera, two laser warp sensors or a line profiler,
optional thermal camera) with sourced price signals, resolution and
eccentricity math, throughput, placement at the Duplex cell and the
Classic, smart-camera vs open GenICam/Aravis/OpenCV/anomalib on NixOS,
specials, Thai channels, next steps.
- Estimate USD 12k-30k hardware per station, ~USD 40k-100k for the two
launch stations; inside the existing metrology launch tier, no plan
price change.
