Pneumatic frame jigs
Four pneumatically operated jigs arranged around the cobot, giving repeatable positioning and the flexibility to hold multiple SKUs.

Eyewear Frame Cleaning SPM
A four-jig cobot cell that strips excess paint from eyewear frames, a delicate step that was slow and inconsistent by hand.

The problem
Excess paint had to be removed from small, fragile regions of each frame using acetone. Doing it manually was slow, tiring and hard to repeat across more than 230 frame SKUs.
What I designed
Foam gripper with acetone line
A custom end effector that holds the cleaning foam and routes acetone through an internal pipeline, so the foam stays soaked throughout the cycle.
SPM enclosure
The full machine structure, panels and safety doors, designed to industrial safety norms.
Outcome
A complete special purpose machine with four dedicated jigs around a cobot, reaching a 1 min 22 sec cycle per frame while handling the full SKU range without changeover.
