A panel clears the stack but catches the tray lip

Split the trial result into retention, single-panel delivery and placement, because the first can pass while the other two fail.
8pointsI've done that in our comments. Supplier says the tray lip is temporary, but it's our production tray in the video. I sent its drawing again.
6pointsGet them to identify the receiving fixture in the revised trial plan so that disagreement doesn't reappear after testing.
16pointsThey acknowledge the tray now. Suggested approaching at a tilt. I haven't agreed because I don't know what that does to the unsupported edge or release.
17pointsHave the tooling and integration people review that proposed movement together; a different angle changes more than the lip clearance.
8pointsDid the lower panel leave the stack or just flex? Those aren't the same failure. I'd want a side view before anyone starts selling you separation hardware.
1pointsYes, establish what the second sheet did and count what arrived, rather than naming a double pick from one ambiguous frame.
5pointsWas the delivered panel flat again after release, or did you keep a bent sample?
2pointsKeep its identity linked to the video if it's available; otherwise a later photo of a bent panel proves very little.
15pointsThey retained that panel. It has a small edge deformation where it met the lip. The side footage shows the lower sheet flexing then settling, so that attempt delivered one panel.
11pointsOur first tooling review spent all its time on vacuum and almost none on the receiving fixture. Curious whether they've proposed more edge support, or are still trying to solve everything by changing the approach.
7pointsThey've proposed extending the tool's support arrangement as well. No dimensions agreed yet. We've asked them to check the extended tool against the tray instead of assuming more support always means more clearance.
15pointsInclude open access for release in that geometry check; an extension can support the sheet and then obstruct its final seating.
17pointsI was too dismissive about the second sheet earlier. Flexing and settling still deserves investigation if it changes unpredictably across the stack. Just don't count it as a confirmed double delivery.
4pointsThat's how we've recorded it: lower-sheet movement observed, one delivered in that attempt. The revised plan includes several stack conditions and inspection of the delivered panels, not just the vacuum trace.
14pointsNew support mock-up cleared the tray in the supplier's static check. They still owe us the reviewed transfer trial and separation evidence. We're keeping the original damaged panel as a comparison sample.
18pointsWhen that transfer trial arrives, check it used the reviewed support arrangement; a static clearance photo and a different tool in the moving clip won't establish the combined result.
