Description

Technical Field

[0001] The utility model relates to a visual detection mechanism, in particular to a visual detection mechanism for the bottom of a barrel surface heat shrink film. Background Art

[0002] In the process of traditional barrel noodle processing and production, heat shrink film wrapping is an indispensable step. The complete heat shrink film can ensure the hygiene and safety of food, and prevent food from getting damp, packaging from being damaged, and other incidents that affect product safety. The integrity detection of heat shrink film relies entirely on human judgment, which is not only time-consuming and labor-intensive, but also prone to missed judgments and misjudgments, making it difficult to control quality. In the existing barrel noodle industry, the inspection agencies have belts blocking the edge of the barrel surface, and the bottom inspection area is mostly imperfect. To solve this problem, we need to use a heat shrink film intelligent visual inspection system to automatically detect the damage and irregular wrinkles of the barrel surface shrink film, so as to save manpower while ensuring product quality.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0019] A visual inspection mechanism for the bottom of a heat shrink film on a barrel surface includes a conveying mechanism and a visual inspection mechanism. The conveying mechanism includes a segmented belt-carrying conveying assembly, and the belt-carrying conveying assembly includes two conveying belts 1. A gap is provided between the two conveying belts 1, and a visual inspection mechanism is set up below the gap. The advantage of this technical solution is that the barrel surface is conveyed to the gap between the two conveying belts 1 by the conveying belts 1, and the visual inspection mechanism below the gap detects the heat shrink film at the bottom of the barrel surface, which solves the problem of dead angles at the bottom of the barrel surface detection, improves the detection rate of damaged barrel surface shrink film and irregular wrinkles, and thus improves product quality.

[0020] In order to prevent the barrel surface from tipping over at the gap during the conveying inspection process, the width of the gap needs to be set smaller than the radius of the bottom surface of the barrel surface.

[0021] During specific implementation, the visual inspection mechanism includes a base 5, a light source assembly 2, a camera assembly and a prism assembly 3. The camera assembly and the prism assembly 3 are mounted on the base 5. The light source assembly 2 is installed on the lower end surface of the conveyor belt 1. The lighting direction of the light source assembly 2 is toward the gap and the lighting direction can be fine-tuned. The prism assembly 3 is mounted directly below the gap. The prism assembly 3 includes a mirror seat 31 installed on the base 5 and a reflecting prism 32 installed on the mirror seat 31. The reflecting prism 32 forms an angle of 45° with the plane where the conveyor belt 1 is located. The camera assembly includes a visual inspection camera 4 whose scanning direction is toward the emission direction of the reflecting prism 32.

[0022] The barrel surface is transmitted to the gap between the conveyor belts 1 through the conveyor belt 1, and the light emitted by the light source component 2 is mapped to the bottom of the barrel surface through the gap. The image is reflected to the visual inspection camera 4 through the reflection prism 32. By adjusting the angle of the light source, images of different qualities are presented. This mechanism solves the problem of blind spots in the bottom of the barrel surface detection, makes the visually collected image clearer, and is more convenient for the calculation of the AI ​​algorithm, shortens the algorithm calculation time, and has higher detection accuracy.

Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
