[0002] In today's industrial production and commodity circulation sectors, the demand for quality control and efficient inspection of goods is extremely urgent. With the continuous expansion of production scale and increasingly fierce market competition, the drawbacks of traditional manual inspection methods are becoming increasingly apparent. Manual inspection is not only inefficient and unable to keep pace with large-scale production, but the results are also greatly affected by the subjective factors of the inspectors, such as fatigue and mood, which can easily lead to inspection errors and increase the risk of substandard products entering the market. At the same time, the cost of manual inspection is constantly rising, including labor costs and training costs, placing significant economic pressure on enterprises. On the other hand, with the rapid development of technology, visual inspection technology is gradually emerging. It can quickly and accurately acquire information such as the appearance, size, and defects of goods, offering higher precision and stability compared to manual inspection.

[0003] Existing vision-based object inspection devices have several shortcomings. Some devices lack precise object positioning, causing the vision inspection components to fail to accurately acquire images, thus affecting the accuracy of the inspection results. Other devices have limited automation, requiring significant manual intervention in object transport, inspection, and handling of defective products, failing to fully leverage the advantages of vision inspection technology. Therefore, those skilled in the art have provided a vision-based object inspection device to address the problems mentioned in the background section. Utility Model Content

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 In this embodiment of the present invention, a device for visually inspecting objects includes a base 1, a guide rail 10, a first limiting plate 15, and a second limiting plate 16. The guide rail 10 is fixedly connected to the left side of the base 1, and a servo motor 11 is fixedly installed on the left side of the guide rail 10. A threaded rod 12 is fixedly connected to the power output end of the servo motor 11, wherein the threaded rod 12 is rotatably connected to the guide rail 10, and a slider is threadedly connected to the threaded rod 12. A connecting plate 13 is fixedly connected to the upper end of the slider, and a push plate 14 is fixedly connected to the right end of the connecting plate 13. A conveying assembly 2 is provided in the middle of the base 1, and the first limiting plate 15 and the second limiting plate 16 are provided above the conveying assembly 2. Two push-pull rods 17 are fixedly connected to one side of both the first limiting plate 15 and the second limiting plate 16, wherein the push-pull rods 17 slide. A rotating plate 18 is rotatably connected to the second limiting plate 16 on the base 1. A receiving box 4 is provided on the right side of the base 1. An opening is provided on the first limiting plate 15, through which the push plate 14 can pass. A sliding groove is provided on the upper end of the guide rail 10, in which the slider is locked. A support frame 6 is fixedly connected to the upper end of the base 1. A servo cylinder 7 is fixedly installed on the upper end of the support frame 6. A piston rod is provided at the lower end of the servo cylinder 7. A vision inspection component 8 is fixedly installed at the lower end of the piston rod. Two front and rear limiting rods 9 are fixedly connected to the upper end of the vision inspection component 8. The limiting rods 9 are slidably connected to the support frame 6. A controller 3 is fixedly installed on the right side of the base 1. Locking casters 5 are fixedly installed at the four corners of the lower end of the base 1. Locking casters 5 are also fixedly installed on the lower left side of the guide rail 10.

[0022] The working principle of this utility model is as follows: In use, the item is first placed on the conveying assembly 2. Then, by pushing and pulling the push-pull rod 17, the first limiting plate 15 and the second limiting plate 16 can slide on the base 1, thereby adjusting the distance between them and confining the item to a suitable central position. This ensures the item is within the accurate detection area during visual inspection. The conveying assembly 2 then transports the item to below the visual inspection assembly 8. The servo cylinder 7 controls the extension and retraction of the piston rod, thereby adjusting the height of the visual inspection assembly 8 to ensure it is at a suitable detection distance for image acquisition of the conveyed item. The visual inspection assembly 8 then uses the acquired image information of the item to... Image processing algorithms and pattern recognition technology are used to compare and analyze the items against preset acceptance standards to determine whether the items are acceptable. When the visual inspection component 8 determines that an item is unacceptable, the controller 3 sends a command to start the servo motor 11. The servo motor 11 drives the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the slider and the slider is locked in the groove of the guide rail 10, the rotation of the threaded rod 12 will cause the slider to move to the right along the guide rail 10. The slider drives the connecting plate 13 and the push plate 14 to move to the right together. The push plate 14 pushes the unacceptable item to the right. The item pushes the rotating plate 18 to rotate, so that the item can fall into the receiving box 4, thereby realizing the separation of the unacceptable item.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
