The invention discloses a visual automatic detecting system for a ceramic cartridge. The visual automatic detecting system comprises a first conveyor belt, a second conveyor belt, a turnover mechanism, a first motor, a second motor, a loading mechanism, a first rejector, a first camera, an unloading mechanism, a second rejector and a second camera as well as an acquisition card, a master control system and a PLC controller, wherein the first rejector and the second rejector are separately arranged behind the first camera and the second camera; and the first camera is used for sending a first to-be-detected face image of a to-be-detected ceramic cartridge to the maser control system for being processed, and the PLC controller directly sends an instruction to the first rejector for rejecting an unqualified product if the first to-be-detected face image is unqualified, so that the unqualified product is prevented from entering a follow-up station, and therefore, the detecting efficiency is conveniently improved; and in a similar way, the second rejector behind the second camera is used for directly rejecting the to-be-detected ceramic cartridge with an unqualified second to-be-detected face image, so that the ceramic cartridge collected by the loading mechanism is a qualified product.
