Porcelain surface roughness automatic detection device

The utility model discloses a porcelain surface roughness automatic detection device which belongs to the technical field of porcelain surface detection. The device includes a power supply management module, a light source device, optical focusing systems (1) and (2), a position sensitive detector (PSD), an amplifier, a signal processing device, and a data display device. The optical focusing systems (1) and (2) are located right in front of the PSD and the light source device. The PSD is firstly connected with the amplifier, then connected with the signal processing device and then finally connected with the data displaying device. The porcelain surface roughness automatic detection device is simple in structure, directly observable and convenient in operation, and capable of real-time rapid and automatic detection of the porcelain surface roughness and automatic generation of a calculation result of the porcelain surface roughness.
