Automated Lens Mounting Fixture

The Automated Lens Mounting Fixture is a critical component of the Precision Optical Lens Inspection and Measurement System. Its primary role is to provide automated, repeatable, and secure handling of optical lenses during the mounting phase prior to inspection. It ensures lenses are held in a precise, predefined orientation and location, eliminating manual handling errors and enabling high-throughput, automated measurement workflows. It interfaces with robotic arms or conveyors to receive lenses, clamps them without inducing stress or contamination, and presents them correctly to subsequent inspection stations such as interferometers or imaging systems.

The fixture typically operates via a pneumatic or servo-electric actuation system. Upon receiving a lens from a feeder or robot, precision alignment pins or optical sensors confirm the lens's rough position. Actuators then drive compliant clamping jaws or vacuum chucks to secure the lens periphery without contacting critical optical surfaces. The fixture may include fine-adjustment mechanisms (e.g., tip-tilt stages) to achieve micron-level positioning accuracy as required by the inspection system's metrology head. A control system, often integrated with the main inspection PLC, coordinates the clamping force, position verification, and handshake signals with upstream and downstream modules.
