Queen-AAD DOE Module

AA DOE Module

It is design to actively align & assemble together DOE Lens with VCSEL Outer Housing into a DOE Module by using High Precision Glue Dispenser and High Accuracy Vision Technologies. The Handler’s in-built Glue Dispenser is integrated with top vision to detect & obtain the positions of the housing to be dispensed with glue. The Glue Dispenser uses a Screw Headed Valve which enables it to perform high viscosity and small diameter glue dispensing with high precision & accuracy. By using multiple vision stations, they capture the X, Y coordinates of both the DOE lens and Housing while aligning & positioning them accordingly before assembling them both together. Curing time only takes <1 sec by using UV Light to perform the job.
