Abstract
The invention discloses a non-contact vancometer, which comprises a hollow shell. A perforated observation hole is formed in the shell. At least one light source which is obliquely aligned with the observation hole is arranged in the shell. By taking the surface where the observation hole is located as a reflecting surface, a glossiness analyzer for receiving reflected light rays is arranged on a reflecting line of light rays emitted by the light source. The non-contact vancometer is characterized in that the glossiness analyzer comprises a CCD (Charge Coupled Device) camera, the CCD camera is connected with an analysis host and the analysis host is used for making analysis according to images transmitted by the CCD camera. The non-contact vancometer has the advantages that since a non-contact design is adopted, the direct contact with a product is prevented, the damage to the product is reduced and the accuracy of the inspection result of the product is also improved; besides, since the CCD camera is used to replace a traditional photosensitive sensor and a specific area is analyzed through a computer, the glossiness analysis of fine parts and irregular areas can be realized.
