Thorough design and continuous optimization of all functional groups lead to superior mechanical stability. Mechanical references with tight tolerances provide a repeatable manufacturing operation from device to device.
The pick-and-place motion system consists of high-precision motion stages with crossed-roller bearings. They are equipped with linear or brushless DC servo motors with optical position feedback for repeatable high-velocity positioning.
The camera system moves independently from the pick-and-place motion stack and carries the syringe or epoxy stamping tool for the resin. This assembly also holds the UV lamps or the light guides.
The motion stages are mounted onto a vibration-isolated structure. This solid set-up makes VersaGlue insensitive against disturbing external influences and provides a high stability during the assembly procedure.
The devices to be mounted are picked up from a custom loading jig or directly from a waffle or Gel-Pak. The pickup tool is centered underneath a rotational stage with a large aperture. The machine vision system recognizes the orientation of the device and brings the gripping tool into the correct rotational position for the placement. A preorientation of the components is not necessary.
