Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tile detection, in particular to a detection device for grading and color separation of ceramic tiles. Background Art

[0002] Ceramic tiles are plate-shaped or block-shaped ceramic products made of clay and other inorganic non-metallic raw materials through molding, sintering and other processes. They are used to decorate and protect the walls and floors of buildings and structures. The grading and color separation of ceramic tiles are mainly achieved through the coordination of online and offline testing. Online testing means setting up a manual inspection station at the end of the production line and at the front end of the product packaging line. The ceramic tiles on the production line are continuously compared with the standard sample tiles by manual labor, so as to select ceramic tiles with color difference and defects (such as cracks, abrasions, broken corners, pinholes, etc.), thereby realizing the grading and color separation of ceramic tiles.

[0003] For example, the patent with publication number CN 111504459 B discloses “a detection device for grading and color separation of ceramic tiles, comprising a detection darkroom, an industrial camera arranged inside the detection darkroom, a detection frame arranged inside the detection darkroom, and a light source arranged inside the detection darkroom; the detection frame is arranged at the lower half of the detection darkroom, and it divides the detection darkroom into two independent spaces, namely a first space and a second space, and the second space is a closed space; the light source is arranged inside the first space, and the industrial camera is located in the second space; wherein the industrial camera comprises a color difference detection camera, an edge detection camera and a brick surface detection camera, and the shooting path of the color difference detection camera is perpendicular to the ceramic tile surface; the light source comprises a first light source for cooperating with the color difference detection camera and the edge detection camera and a second light source for cooperating with the brick surface detection camera, and the first light source emits white light and infrared rays.

[0004] However, the detection frame of the above patent can be glass or transparent partition. After long-term use, the glass / transparent partition is easily scratched by the wear of ceramic tiles. When light passes through the glass / transparent partition, it is easy to refract or scatter the light, resulting in poor clarity of the camera's shooting picture, which in turn causes errors in the grading and color separation of the tiles. In addition, if Figure 1 As shown, the detection frame of the above patent has a slope. When the ceramic tiles are continuously moved, the edges of the ceramic tiles will collide with the lower side wall of the detection darkroom, which may easily cause the ceramic tiles to break.
