Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, specifically a visual inspection device for agricultural product outer packaging labels. Background Technology

[0002] Visual inspection technology is a technique that uses optical imaging systems and image processing algorithms to automatically detect the appearance features, size, defects, etc. of objects. It simulates the human visual system, capturing images of objects through cameras and then using computer vision algorithms to analyze and process the images to achieve functions such as object detection, recognition, measurement, and classification. In agricultural production, some products, such as nuts, can be sealed in plastic bags filled with inert gases like nitrogen to prevent oxidation and spoilage. Visual inspection technology can typically be used to check the integrity, color, and appearance of the outer packaging and labels. This relies on images captured by a camera. Current production processes are mostly semi-automatic or automated, with products transported via conveyor belts. However, during production, some packaging bags may become dented or wrinkled due to collisions, affecting camera capture and resulting in incomplete image information. This negatively impacts the effectiveness of visual inspection, causing inconvenience. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the present invention, a visual inspection device for agricultural product outer packaging labels includes: The package includes a box body 100, a frame 200, a drive mechanism 300, and a pressing mechanism 400 that can press the surface of the packaging bag to reduce wrinkles. A rectangular notch is provided on one side of the box body 100. One side of the frame 200 is rotatably connected to the top of an inner wall of the box body 100. Rotating shafts are rotatably connected to the centers of two opposite inner walls of the frame 200, and a support plate 210 is fixedly connected between the two rotating shafts. The drive mechanism 300 is located inside the box body 100, and the pressing mechanism 400 is located inside the box body 100. Above the body 100, the pressing mechanism 400 includes a U-shaped plate 410, and the bottom ends of the two arms of the U-shaped plate 410 are fixedly connected to the two ends of the top surface of the box body 100 respectively. A cylinder 420 is fixedly connected to the top surface of the U-shaped plate 410, and the movable end of the cylinder 420 passes through the top surface of the U-shaped plate 410 and is fixedly connected to a movable plate 430. A pressure plate 440 is provided below the movable plate 430, and multiple rebound springs 441 are fixedly connected between the pressure plate 440 and the movable plate 430.

[0016] Specifically, by placing the box 100 onto the conveyor belt, the conveyor belt transports the product to the frame 200 where it is supported by the pallet 210. Then, the cylinder 420 is activated to move the moving plate 430 and the pressure plate 440 downwards simultaneously. The pressure plate 440 presses the outer packaging of the product onto the pallet 210, thereby compressing the outer packaging bag. The pressure causes the nitrogen gas filled inside the packaging bag to redistribute, filling the gaps at the creases and restoring flatness, thus reducing wrinkles on the surface of the outer packaging. A camera facilitates visual inspection of the product packaging, thereby improving the visual inspection effect. When the pressure plate 440 presses the product packaging, the moving plate 430 does not contact the pressure plate 440 or the packaging bag. The return spring 441 has a small diameter and low elasticity. When the moving plate 430 moves the pressure plate 440 down, after the pressure plate 440 contacts the packaging bag, the rebound force generated by compressing the return spring 441 can press the packaging bag, avoiding excessive pressure on the packaging bag and causing it to break.

[0017] Example 1 like Figure 2-4 As shown, in this embodiment, both the tray 210 and the pressure plate 440 are made of plastic. Camera modules are provided on the bottom surface of the inner surface of the box 100 and the bottom surface of the movable plate 430. An electric push rod 110 is fixedly connected to one side of the box 100, and a slide rail 220 is fixedly connected to the other side of the frame 200. A slider is slidably engaged inside the slide rail 220, and the movable end of the electric push rod 110 is rotatably connected to the slider.

[0018] In this embodiment, both the pallet 210 and the pressure plate 440 are made of plastic, making the pressure plate 440 lightweight and less likely to exert excessive pressure on the packaging bag. Furthermore, both the pressure plate 440 and the pallet 210 are made of transparent plastic. By installing camera modules on the bottom surface of the box 100 and the bottom surface of the moving plate 430, the camera modules, in conjunction with machine vision inspection technology, can be used to visually inspect the product's outer packaging. When the product falls onto the pallet 210, the electric push rod 1 can be activated. 10 moves the other side of the frame 200, causing the frame 200 to rotate around its own axis and tilt, so that the outer packaging of the product on the pallet 210 slides along the tilted surface of the pallet 210, thereby adjusting the position of the packaging bag on the pallet 210. When it is necessary to remove the packaging bag from the pallet 210, the electric push rod 110 can be activated to tilt the other side of the frame 200 downward, so that the packaging bag on the pallet 210 slides down from the rectangular notch of the box 100 along the pallet 210 and gets off the pallet 210.

[0019] like Figure 3-4 As shown, in this embodiment, the drive mechanism 300 includes: Two motor boxes 310 and two turntables 320 are provided. The two motor boxes 310 are fixedly connected to one side of the box body 100. Each of the two motor boxes 310 is equipped with a drive motor. The motor shafts of the two drive motors pass through one side of the box body 100 and are fixedly connected to a rotating rod. The center of one side of each of the two turntables 320 is fixedly connected to one end of each of the two rotating rods. Pull rods are rotatably connected to the outer ring edge of the other side of each of the two turntables 320. Pull ropes 211 are fixedly connected to both ends of the bottom surface of the support plate 210. One end of each of the two pull ropes 211 is fixedly connected to one of the two pull rods.

[0020] In practice, when the frame 200 is placed flat and the pressure plate 440 presses the packaging bag onto the pallet 210, the controller starts two drive motors, which drive the two turntables 320 to rotate. The two turntables 320 pull the two pull ropes 211 using their own pull rods. At this time, the two pull rods are arranged diagonally with the center of the distance between the two turntables 320 as the center, so that the two pull ropes 211 drive the pallet 210 to tilt back and forth, causing it to shake. The material in the packaging bag is shaken evenly, making it easier for the pressure plate 440 to flatten the packaging bag. When the frame 200 is pushed up by the electric push rod 110 on the other side, the pallet 210 can pull the two pull rods to the top of the adjacent turntable 320 through the two pull ropes 211, so that the pull ropes 211 follow the tilt of the frame 200. When the frame 200 is pulled down by the electric push rod 110 on the other side, the two pull ropes 211 can naturally loosen.

[0021] Example 2 Based on Embodiment 1, the connecting membrane 201 is provided to facilitate the limiting of the tray 210.

[0022] like Figure 2-4 As shown, in this embodiment, a connecting membrane 201 is fixedly connected between the inner wall of the frame 200 and the outer wall of the tray 210. The connecting membrane 201 is made of rubber.

[0023] In practice, the connecting film 201 is made of soft rubber material, which is elastic and can be stretched. When the pallet 210 is pulled by the pull rope 211 and tilts back and forth inside the frame 200, the connecting film 201 can be stretched. When the pallet 210 is not pulled by the pull rope 211, the connecting film 201 can keep the top surface of the pallet 210 parallel to the top surface of the frame 200, so as to prevent the pallet 210 from rotating naturally and causing the packaging bag to fall off the pallet 210.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] 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.
