Our setup uses Fairino FR5 for tray unloading with a rigid spacer block in a supervised production bench. We've repeatedly adjusted pickup points as handling becomes unreliable.
Although the tray appears unchanged, the grip no longer looks as square. I'd like an inspection sequence that helps us identify the cause before making further teaching changes or attributing it to the arm.
@EmmaChen1159 Look at the relationship between the workpiece and fixture before contact, then during gripping. Can your existing observations show when the change in angle begins?
Reviewing the recording, I can see consistent seating in the checked fixture before pickup. The workpiece changes angle during gripping rather than arriving in that position.
Keep a copy of the current configuration and hold off on further coordinate changes. Under the appropriate isolation procedure, maintenance can use the observed rotation to focus inspection on tooling contact, mounting and tray seating.
You're right; the history supports a check, not a conclusion. Inspect the pad installation and gripping surfaces while retaining tray location in the investigation.
@SarahAllen0328 My separate handling setup had both worn gripping surfaces and variation in tray seating. Coordinate corrections alone gave inconsistent results because they didn't address either underlying condition.
With multiple point changes already in our history, I'm unsure how to distinguish tooling and tray effects. How did you structure that comparison on your setup?
