| AEi implemented a solution using a granite subplate with passive vibration isolation,
sub-micron resolution motion stages, high-magnification
vision system with coaxial and off-axis lighting, and
an air-bearing flexure compliant vacuum tool to pick
the lens from the part nest, position it inside the
camera package with a measured and repeatable seating
force, and dispense and UV-cure epoxy to bond the lens
in the aligned position.
Cleanliness on the interior
of the machine was vital to ensure that none of the
high-cost assemblies were lost due to contamination
of the lens or camera sensor during assembly. The
system utilized fully automated pattern recognition,
material
handling, and calibration sequences to minimize operator
requirements and contamination. The software provided
flexibility to allow the customer to easily modify
the sequence, or create new ones, to support their
evolving geometries, dispense patterns, and process
improvement efforts.
