LIGHT LINE IMAGER-BASED IC TRAY POCKET DETECTION SYSTEM

A system for detecting a status of a pocket of a tray includes a tray having a plurality of pockets that hold an integrated circuit device, a vision mechanism, a light line generator, a reflective device, and a controller. The vision mechanism images the tray along a first optical axis. The light li...

Zusammenfassung:	A system for detecting a status of a pocket of a tray includes a tray having a plurality of pockets that hold an integrated circuit device, a vision mechanism, a light line generator, a reflective device, and a controller. The vision mechanism images the tray along a first optical axis. The light line generator emits a light line along a second optical axis. The reflective device reflects the light line onto the tray along a third optical axis. The third optical axis has a different angle relative to the first optical axis than an angle between the first optical axis and the second optical axis. The controller receives an image of the tray from the vision mechanism, detects the light line reflected onto the tray along the third optical axis, and determines a status of a pocket based on the detected light line along the third optical axis.
