Description

Technical Field

[0002] Cat treat packaging inspection equipment is an automated device specifically designed for the quality inspection of cat treat packaging, encompassing functions such as automatic metering, filling, bag making, and sealing.

[0003] Currently, most cat treat packaging inspection equipment on the market relies on a single identification technology. This single identification method has significant limitations in practical applications, especially when it comes to accurately identifying the quality of the packaging seal. Due to the limitations of the identification method, when companies face large-scale, high-intensity production tasks, existing inspection equipment often cannot fully cover all packaging details or efficiently ensure that every food package meets strict quality standards. This, to some extent, affects the overall quality of the product and the company's production efficiency. Therefore, this utility model proposes a 3D visual false seal detection system for cat treats to solve the above problems. Utility Model Content

Detailed Implementation

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Reference Figures 1-8 As shown, a 3D visual false seal detection system for cat-shaped stripes includes a central shielding shell 3. Multiple horizontal bars 4 are fixedly connected inside the central shielding shell 3. Multiple vertical bars 5 are fixedly connected between two horizontal bars 4. A fixing connecting plate 9 is fixedly connected to the upper surface of each vertical bar 5. An X-ray detection box 23 is fixedly connected to one side of two horizontal bars 4 that are close to each other. A conveyor belt support rod 10 is fixedly connected to one side of the multiple fixing connecting plates 9 that are close to each other. Module connecting plates 15 are fixedly connected to both sides of the conveyor belt support rod 10. 15. 3D detection modules 14 are fixedly connected to each other on one side. Multiple uprights 6 are fixedly connected to the outer surface of the crossbar 4. The top of the uprights 6 is fixedly connected to the top of the top frame 7. Support connecting rods 8 are fixedly connected to the front and back sides of the inner wall of the top frame 7. X-ray generator 19 is fixedly connected to the upper surface of the support connecting rod 8. Collimator 20 is set on the lower side of X-ray generator 19. 2D camera connecting plate 21 is fixedly connected to the left side of X-ray generator 19. 2D line scan camera module 22 is fixedly connected to the left side of 2D camera connecting plate 21.

[0028] Specifically, a frame is formed by combining multiple horizontal bars 4, vertical bars 5, and uprights 6 to support the equipment and structure. A central shielding shell 3 installed on the outer side protects the equipment and personnel. A lead liner installed inside the central shielding shell 3 blocks a certain amount of X-rays. Conveyor belt support rods 10 are installed inside the frame via fixed connecting plates 9 and supported by horizontal bars 4 and vertical bars 5. 3D inspection modules 14 are fixed to the front and rear sides of the conveyor belt support rods 10 via module connecting plates 15. The 3D inspection module 14 photographs and inspects the seals at both ends of the material to initially check for seal integrity. Subsequently, a 2D line installed to the left of the X-ray generator 19... The scanning camera module 22 scans the packaging to form an image. Then, the top frame 7 and the support connecting rod 8 inside the top frame 7 are supported by the middle shielding shell 3. The support connecting rod 8 supports and fixes the X-ray generator 19 installed on the upper side. The X-ray generator 19 generates X-rays, and the collimator 20 on the lower side limits the direction and range of the X-ray irradiation to prevent damage to surrounding equipment and personnel. Then, the X-ray detection box 23 on the lower side collects the image of the X-ray irradiation range, which facilitates subsequent image analysis. At the same time, by fusing the image with the image scanned by the 2D line scanning camera module 22, the detection results are more accurate, and the detection speed can be greatly increased while ensuring the accuracy of the results.

[0029] Reference Figures 1-6 As shown, the collimator 20 corresponds to the X-ray detector box 23, and the collimator 20 is used to limit the X-ray irradiation range; a light source bracket 17 is fixedly connected to the lower surface of the top frame 7, and a supplementary light source 18 is fixedly connected to the left side of the light source bracket 17; the X-ray detector box 23 is used to receive X-rays and perform imaging processing, and the supplementary light source 18 is used to supplement the brightness inside the middle shielding shell 3; a bottom support shell 2 is fixedly connected to the lower surface of the middle shielding shell 3, and an upper shell 1 is fixedly connected to the upper surface of the middle shielding shell 3; the X-ray generator 19 and the 2D line scan camera module 22 are both located inside the middle shielding shell 3;

[0030] Specifically, the collimator 20 corresponds to the X-ray detector box 23, making it easier for the X-ray detector box 23 to collect the image formed after X-ray irradiation. At the same time, the collimator 20 limits the direction and range of X-ray irradiation, thereby ensuring the safety of equipment and personnel. The supplementary light source 18 on the lower side is fixed to the lower side of the top frame 7 by the light source bracket 17, providing a light source for the interior of the middle shielding shell 3, thereby ensuring the brightness inside the middle shielding shell 3, so that the images captured by the 3D detection module 14 and the 2D line scan camera module 22 are consistent and the images are clear. The bottom support shell 2 on the lower side supports the equipment, and the upper shell 1 on the upper side protects the X-ray generator 19 and the 2D line scan camera module 22, ensuring the normal operation of the equipment.

[0031] Reference Figures 4-5 As shown, a drive module 12 is provided at the right end of the conveyor belt support rod 10, and a timing belt 11 is provided on the outer side of the conveyor belt support rod 10; multiple material limiting plates 13 are fixedly connected to the outer surface of the timing belt 11, and sensor modules 16 are provided symmetrically on both the front and rear sides of the conveyor belt support rod 10.

[0032] Specifically, the timing belt 11 is supported by the conveyor belt support rod 10, and the drive module 12 is fixed so that the drive module 12 can drive the timing belt 11 to operate, thereby facilitating the movement of the material restriction plate 13 on the upper side of the timing belt 11. The material restriction plate 13 can then be used to transport materials while restricting the orientation of the materials so that the two seals face the front and rear sides respectively. At the same time, multiple sensor modules 16 set on both sides count the materials and provide signals for the start-up and photography of the rear equipment.

[0033] Working principle: During use, the drive module 12 drives the timing belt 11 and the material limiting plate 13 to move. At the same time, the material limiting plate 13 carries the material and can correct the direction of the material, so that the sealing openings at both ends are located on the front and rear sides of the material limiting plate 13. Then, the timing belt 11 conveys the material. The sensor module 16 installed on the left side detects the material to ensure that the material enters the middle shielding shell 3. At the same time, it transmits signals into the middle shielding shell 3 to facilitate subsequent detection of the sealing openings at both ends of the material.

[0034] The seal is then inspected by 3D detection modules 14 installed on both sides of the conveyor belt support rod 10. Subsequently, the seal is scanned by 2D line scan camera module 22 installed on the left side of X-ray generator 19. At the same time, the seals at both ends of the material are judged by combining the detection images from the X-ray detector box 23 on the right side. This helps to detect whether there is a false seal, thereby increasing the accuracy of the inspection. It also makes it easier to handle the inspection of large quantities of materials and improves the inspection efficiency.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
