ABSTRACT:
A vision alignment system and method is provided. The vision alignment system includes one or more grouped alignment plates with guiding inserts configured to receive multiple devices, and groups of three actuators, configured to actuate the alignment plates to correct the position offsets of multiple devices as a group. The position offsets between the device and contactor are determined by a device-view camera during runtime and a contactor-view camera during calibration time. The vision alignment system also includes a pick-and-place handler, configured to transport devices.
