The invention relates to a sanitary ceramic production and detection device, in particular to a sanitary ceramic semifinished product detection line. The sanitary ceramic semifinished product detection line comprises a material feeding conveying device for conveying a sanitary ceramic blank body, transverse movement transitional devices for shunting of the material feeding conveying device, discharging conveying devices for conveying a sanitary ceramic and disqualified product conveying devices for conveying disqualified products, wherein the discharging conveying devices are arranged on two sides of the material feeding conveying device; the transverse movement transitional devices are arranged between the material feeding conveying device and both the discharging conveying devices; two ends of the transverse movement transitional devices are respectively butted with the material feeding conveying device and the discharging conveying devices; the discharging conveying devices are connected with the disqualified product conveying devices; the disqualified product conveying devices are used for shunting disqualified sanitary ceramic products in the discharging conveying devices; and a fixture plate and a radio frequency plate are combined to form a device with detection and classification functions. Therefore, the labor can be saved, and the efficiency can be improved; and the most important is that the classification accuracy is high, and loss caused by wrong classification is avoided.
