The invention relates to the technical field of panel optical inspection devices, in particular to a panel inspection device. The panel inspection device comprises a base, and is characterized in thata sheet allocating device, an automatic optical inspection device, a discharging device and a storing device are sequentially arranged in the conveying direction of a panel on the base. The sheet allocating device is used for bearing a to-be-inspected panel to be transferred to an inspection platform on the automatic inspection device. The automatic optical inspection device is used for performing optical inspection on the to-be-inspected panel on the inspection platform. The discharging device is used for transferring the panel which is identified as a finished product by the automatic optical inspection device. The storing device is used for storing the panel which is identified as an NG product by the automatic optical inspection device. The panel inspection device is reasonable in structural layout, is high in panel inspection efficiency, improves the panel inspection efficiency greatly, and has a great popularization value.
