Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dried fruit detection, in particular to a high-speed dried fruit detection mechanism and a visual system. Background Art
[0002] With the continuous development of the global food market and increasing consumer demand for food quality, the quality of dried fruit products has become a key indicator of their market competitiveness. Traditional manual inspection methods are limited by the experience, fatigue, and subjective judgment of inspectors, making it difficult to ensure the stability and consistency of test results. Furthermore, they are inefficient and unable to meet the needs of modern large-scale production lines. Therefore, the development of an intelligent system that can automatically, quickly, and accurately detect the size, contour, shape, and appearance defects of dried fruit materials is of great significance for improving production efficiency, ensuring product quality, and reducing labor costs. Utility Model Content
[0003] In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art and provide a high-speed dried fruit detection mechanism and visual system. This application provides the following technical solutions:
[0004] It includes a material conveyor belt, which is provided with a carrying structure for carrying dried fruits. The bottom of the carrying structure is hollowed out to expose the bottom of the dried fruits; visual inspection systems are provided above and below the carrying structure, and the visual inspection systems are used to photograph the dried fruits.
[0005] By hollowing out the loading structure, the top and bottom of the dried fruits are exposed while they are being transported. The visual inspection system then captures both the top and bottom of the dried fruits, enabling a more comprehensive, rapid, and accurate inspection of their appearance.
[0006] The material conveyor belt includes a driving wheel and a follower wheel arranged transversely, and a tensioning wheel is further arranged below the driving wheel and the follower wheel; the driving wheel, the follower wheel and the tensioning wheel are equipped with a belt for transmission.
[0007] The loading structure includes a number of loading V-blocks arranged in sequence, a through groove is provided in the middle of the loading V-block, and protrusions for supporting the two sides of the dried fruits are provided on the side walls of the through groove. There are two belts and they are arranged in parallel on the driving wheel, the follower wheel and the tensioning wheel. The two ends of the loading V-block are respectively connected to the two belts.
[0008] By setting the object-carrying V-block, when both sides of the dried fruit are lifted by the protrusions, the dried fruit is located in the through slot, so that the visual inspection system can take pictures of the bottom of the dried fruit through the through slot.
[0009] The visual inspection system includes an upper visual camera arranged above the carrier V-block and a lower visual camera arranged below the carrier V-block. The upper visual camera is used to photograph the upper part of the dried fruit; the lower visual camera is used to photograph the bottom of the dried fruit.
[0010] The lower visual camera is arranged horizontally, and a reflector is arranged in the direction facing the lens of the lower visual camera. The reflector surface is arranged at 45 degrees, and is used to reflect the bottom image of the dried fruit above it to the lower visual camera.
[0011] By setting the lower visual camera horizontally and installing a reflector, small debris and dust from the dried fruits above it can be prevented from falling onto the camera lens and affecting the lens's shooting image.
[0012] The reflector is provided with an impurity cleaning system, which includes a high-speed blowing air knife and a cleaning brush; the high-speed blowing air knife is fixed on the upper part of the reflector and is used to sweep the mirror surface of the reflector. An electric linear guide is installed on the high-speed blowing air knife, and one end of the cleaning brush is installed on the electric linear guide. The cleaning brush is parallel to the reflector and the brush head is in contact with the mirror surface.
[0013] By setting up an impurity cleaning system, the mirror surface of the reflector can be cleaned when the reflector is dirty, and the image reflected on the reflector is clearer when the lower visual camera is used to shoot it.
[0014] The visual inspection system also includes an upper light source located above the object-carrying V-block and a lower light source located below the object-carrying V-block. The upper light source is used to illuminate the upper part of the dried fruit, and the lower light source is used to illuminate the lower part of the dried fruit.
[0015] By setting the light source for lighting, the shooting picture will be clearer.
[0016] The upper light source and the lower light source are frame-shaped, with lamp beads arranged around them and a through middle.
[0017] The frame design is adopted. When the upper light source and the lower light source are facing the dried fruits, the upper visual camera and the lower visual camera can shoot the dried fruits through the center.
[0018] The visual inspection system also includes a lower background plate and an upper background plate. The lower background plate is fixed above the object-carrying V-block and faces the reflector. The upper background plate is fixed below the object-carrying V-block and faces the upper visual camera.
[0019] By setting a background board as the background of the upper visual camera and the lower design camera, the content of the picture other than the dried fruits can be reduced, which facilitates the subsequent processing of the picture.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0021] Through the precisely designed material conveying mechanism, the use of a high-resolution visual imaging system and an intelligent impurity cleaning system, comprehensive, rapid and accurate inspection of the appearance of dried fruit materials is achieved.
