Description

Technical Field

[0001] The utility model relates to the technical field of visual inspection, in particular to a novel visual inspection counting device. Background Technique

[0002] Today, with the rapid development of technology, researchers have gradually deepened their research on the visual inspection of materials such as granular, flaky, capsules, and toy building blocks. As a kind of visual inspection research, the visual inspection counting device is also relatively commonly used.

[0003] For example, a novel visual inspection counting device with the patent number CN221115528U includes a camera, a light source, and a conveying mechanism. The conveying mechanism includes a transmission structure and a conveyor belt. The conveyor belt is wound around the transmission structure, and a light-absorbing material is attached to the conveyor belt. The light source is located above the conveyor belt. The above document still has deficiencies. When in use, a light-absorbing material is attached to the conveyor belt. The light source is located above the conveyor belt, and the camera is also located above the conveyor belt. The material is conveyed on the conveyor belt. Under the irradiation of the light source, through the absorption of light by the light-absorbing material on the conveyor belt and the reflection of light by the surface of the material, a dark contrast is formed between the material and the surrounding environment, so that the contour shape of the material is detected by the camera and clearly imaged on the computer display screen, thus avoiding the phenomenon of reflection. However, when the above-mentioned visual inspection technology device is in use, the height of the camera is fixed. When the items to be detected and counted are large, it is easy to scratch the camera. When the items to be detected and counted are small, the detection effect will be reduced due to the long distance. When in use, it is not convenient to adjust the height of the camera according to the actual use requirements. At the same time, the angle of the camera is fixed, and it can only detect the items in the vertical direction, and it is not convenient to adjust the angle of the camera according to the actual use requirements to detect and count the sides of the items.
