  • Patent number: 9612191
    Abstract: An inspection device for a substrate includes a support member, a turning table and a first drive device. The turning table includes: a carrier pivotally mounted on a pivot shaft, the carrier having an observation aperture through its thickness direction; and positioning clamps which are mounted on the carrier and are used to retain the display substrate in the range of the observation aperture. The first drive device is in transmission connection with the pivot shaft of the carrier in order to drive the turning table to rotate around the pivot shaft. In use, an omnidirectional inspection of the display substrate can be achieved by turning the turning table. Moreover, the contact between the inspector and the display substrate can be avoided, the risk of damaging the display substrate during appearance inspection can be decreased, and therefore defects of the display substrate caused by appearance inspection can be reduced.
