Beschreibung
Zusammenfassung:	The present invention provides an automated optical inspection system from production line of TFT LCD (thin film transistor liquid crystal display) panel manufacturing process, which includes a mini clean room, at least a gantry disposed in the mini clean room and having a camera thereon, at least a particulate air filter disposed on an upper top cover of the mini clean room, a panel conveyor disposed under the camera for loading the panel to be inspected, at least a lamp house providing at least a light source for the illumination necessary for photograph, and at least a light guide for guiding the light irradiated from the lamp house to the place at which the panel to be inspected on the panel conveyor in the mini clean room is located. When the light guided by the light guide illuminates on the panel to be inspected, the panel to be inspected can be determined if any foreign matter or defect presents thereon by means of the image acquired by the camera. Besides, in case of lamp house failure, it is not necessary to open the mini clean room for light source replacement. Furthermore, the present invention provides a light source distribution method of the automatic optical inspection system for production line of TFT LCD panel manufacturing process.
