Example Embodiment

[0016] Specific embodiments of the present invention will be further described in detail below.

[0017] like figure 1 As shown, a non-contact gloss meter of the present invention includes a hollow casing 10 , which is a semi-cylindrical structure, including a flat surface 12 and an arc-shaped surface 14 . Wherein, a penetrating observation hole (not shown) is provided in the middle of the plane 12 . The observation hole is used to get close to the measured object to observe the measured object. Two parallel light generators 20 are disposed on the arc surface 14 . The parallel light generator 20 comprises a light source 22, a first convex lens 24 and a second convex lens 26 in turn, and a light shielding plate 28 which seals the cylinder 18 into two parts is also arranged between the first convex lens 24 and the second convex lens 26. A through circular hole 30 is set on the plate 28, and the circular hole 30 is just located on the focal point of the first convex lens 24, s...

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.

Description

technical field [0001] The invention relates to an optical detection device, in particular to a non-contact gloss meter. Background technique [0002] Gloss is a physical quantity that evaluates the ability of the surface of a material to reflect light under a set of geometrically specified conditions, and has a direction-selective reflection property. Gloss meter, also called gloss meter, is an instrument used to measure the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, hardware and other materials. The gloss meter uses the principle of light reflection to measure the gloss of the sample. That is: to irradiate the sample under the conditions of specified incident angle and specified light beam to obtain a light source in the direction of the specular reflection angle. The measuring head of glossiness is composed of a transmitter and a receiver, and the transmitter is composed of a light source and a set of lenses, which generate a certain required i...
