The invention discloses an OLED (organic light emitting diode) substrate transfer trolley, comprising a movable trolley body, a storage box arranged on the trolley body, as well as a power mechanism and a brake mechanism arranged inside the trolley body; the storage box is a hollow sealed box body and is used for storing an OLED substrate; a valve is arranged on the storage box; the valve is connected with a nitrogen source; a handrail is further arranged at the rear end of the trolley body. According to the transfer trolley disclosed by the invention, the storage box filled with the nitrogen is arranged on the movable trolley so that the OLED substrate is protected in the transfer process and the pollution to the OLED substrate due to particles is prevented; the nitrogen concentration in the storage box is controlled automatically by a pressure detection control device, so the automation degree is high; because the OLED substrate in a cartridge can be matched with a manipulator, automatic operation of picking and placing the OLED substrate is realized.
