Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bottle label detection, and in particular to a fully automatic bottle label precision inspection machine. Background Art
[0002] Labels for bottled products (such as beverages and alcoholic beverages) are a key vehicle for conveying product information (e.g., ingredients, expiration date, batch number), showcasing brand image, and meeting regulatory requirements. They directly impact consumer trust and market compliance—missing or inaccurate content can lead to legal risks or recalls. Therefore, rigorous label inspections are essential during the production process to prevent errors, omissions (e.g., dates, barcodes), and defacement. Furthermore, label defects (e.g., misalignment, wrinkles, and blurred printing) can be minimized, helping to maintain brand reputation.
[0003] Currently, bottle label inspection usually uses a visual recognition system. This system uses high-resolution industrial cameras and advanced image processing algorithms to capture images of the bottle surface from different angles, ensuring full coverage of all angles. This allows for a full, all-around scan of the label, detecting tiny flaws. Furthermore, the system enables continuous loading and unloading, supporting fast and stable transport of bottles to be inspected, and achieving automatic inspection.
[0004] Most existing wine bottles are curved or irregularly shaped glass bottles, and some are even made of transparent materials. The images collected by traditional lighting methods are seriously affected by reflections and deformation, resulting in poor image quality and difficulty in obtaining effective visual information for image processing. Especially when the glass device has an irregular shape, a single camera and a single light source are often unable to cover all target areas at the same time, resulting in increased detection time and affected detection efficiency.

[0017] Compared with the existing technology, the present invention provides a fully automatic bottle label inspection machine with the following beneficial effects:
[0018] 1. This fully automatic bottle label inspection machine can perform multi-directional inspection on bottles by installing top, front and bottom cameras in the inspection box. During the front camera inspection, the bottle rotates to achieve all-round inspection. At the same time, top fill light, arch fill light, plane fill light and bottom fill light are installed to achieve coverage of the inspection target area, reduce inspection time and help improve inspection efficiency.
[0019] 2. This fully automatic bottle label inspection machine is equipped with a top camera, front camera, bottom camera, top fill light, plane fill light and bottom fill light, all of which are arranged in the inspection box through an adjustment mechanism to adjust the detection distance and fill light distance.

[0020] 3. This fully automatic bottle label inspection machine places the first and second conveyor racks on either side of the arched fill light, which not only allows the loading and qualified products to be placed separately, reducing the possibility of material mixing, but also helps reduce the size and transfer distance of the robotic arm by placing them on both sides of the arched fill light, thus improving the user experience.
[0021] 4. This fully automatic bottle label inspection machine uses a robotic arm to put defective products into the discharge bin.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.
[0032] Example:
[0033] Reference Figures 1-6, a fully automatic bottle label inspection machine, including an inspection box 1, the inspection box 1 is a cube structure, and adjustable feet are fixedly set at the bottom of the inspection box 1 to facilitate the adjustment of the level of the inspection box 1, and also includes: an inspection conveyor line for conveying bottles, which is arranged in the inspection box 1 and is used for loading products, unloading qualified products and unloading defective products when in use; a top camera 2 for inspecting the label on the top of the bottle is installed in the inspection box 1, that is, the inspection end of the top camera 2 faces downward, and a top fill light 6 matching the top camera 2 is provided in the inspection box 1, square At least one group of front cameras 3 is installed in the detection box 1 to detect the label on the bottle body. An arched fill light 7 is fixed in the detection box 1. The arched fill light 7 has a semicircular structure, and one end of the opening is far away from the front camera 3. The arched fill light 7 can not only fill light for the curved bottle body, but also facilitate fill light during the rotation process. Here, we prefer to have two groups of front cameras 3. The two groups of front cameras 3 are distributed up and down along the axis of the arched fill light 7. The axis of the arched fill light 7 is perpendicular to the horizontal plane, and the front The detection end of the camera 3 extends into the arched fill light 7, and a detection hole is opened on the side wall of the arched fill light 7. During detection, the detection ends of the two groups of front cameras 3 face the detection holes, and the axes of the front cameras 3 and the arched fill light 7 are perpendicular to each other. In addition, a plane fill light 8 is set in the detection box 1, and the plane fill light 8 is arranged opposite to the front camera 3, that is, the luminous surface of the plane fill light 8 is arranged face to face with the detection end of the front camera 3. When filling light on the transparent bottle body, it is difficult for light to penetrate the label, which makes it easier for the front camera 3 to detect bubbles and wrinkles in the label. Wrinkles and other problems are detected, and a mechanical arm 5 is provided in the detection box 1. A base is rotatably provided on the mechanical arm 5, and the base is fixed in the detection box 1. The mechanical arm 5 has two rotation points, the first is the main arm and the base are rotatably connected, and the second is the auxiliary arm and the main arm are rotatably connected, which is convenient for the mechanical arm 5 to change the grasping direction. The mechanical arm 5 has two states: transferring products and rotating products. When the mechanical arm 5 is in the transferring state, the product is transferred in the detection conveyor line and the arch fill light 7. When the mechanical arm 5 is in the rotating state, the product rotates in the arch fill light 7.The bottom camera 4 is used to detect the label on the bottom of the bottle. The detection end of the bottom camera 4 faces upward and is installed below the arch fill light 7. The detection end of the bottom camera 4 extends into the arch fill light 7. The axis of the bottom camera 4 coincides with the axis of the arch fill light 7. In addition, a bottom fill light 9 matching the bottom camera 4 is fixedly provided in the detection box 1. The top fill light 6 and the bottom fill light 9 are both annular structures. The axes of the top camera 2 and the bottom camera 4 coincide with the axes of the top fill light 6 and the bottom fill light 9 respectively. The light-emitting surface of the top fill light 6 is downward, and the bottom fill light 9 is aligned with the top fill light 6. The luminous surface faces upward, facilitating fill-in lighting. Here, when the inspection conveyor line conveys a product below the top camera 2, the top camera 2 inspects the top of the bottle. After the inspection is complete, the robotic arm 5 grabs the product. If the top camera 2 detects that the product is qualified, it can be transferred to the arched fill-in light 7 for further inspection. If the product fails, it is transferred to the defective area of the inspection conveyor line. Similarly, if either the front camera 3 or the bottom camera 4 fails, the robotic arm 5 will transfer the product to the defective area. If both pass, the product is transferred to the qualified area of the inspection conveyor line for easy use in the next step.
[0034] During use, by respectively setting a top camera 2, a front camera 3 and a bottom camera 4 in the detection box 1, the bottle body can be inspected from multiple directions. Moreover, when the front camera 3 is inspecting, the bottle body rotates to realize all-round inspection. At the same time, a top fill light 6, an arch fill light 7, a plane fill light 8 and a bottom fill light 9 are set to achieve coverage of the detection target area, reduce the detection time, and help improve the detection efficiency.
[0035] Reference Figure 3-Figure 5 Here, in order to facilitate the adjustment of the detection camera and the fill light, the top camera 2, the front camera 3, the bottom camera 4, the top fill light 6, the plane fill light 8 and the bottom fill light 9 are all arranged in the detection box 1 through an adjustment mechanism to adjust the detection distance and the fill light distance. When the height and diameter of the bottle body change according to actual usage, the detection distance and the fill light distance can be adjusted to improve the use effect. Here, we prefer the model of the detection camera to be WF-200VN.
[0036] Reference Figure 3-Figure 5 Here, we design the adjustment mechanism as a slide rail 201 fixedly installed in the detection box 1, a slide table 202 is slidably connected to the slide rail 201, and a mounting plate 203 for fixing the camera and fill light is fixed to the slide table 202 by bolts. The camera and fill light are also fixed to the mounting plate 203 by bolts. The sliding direction of the slide table 202 is to slide along the axis of the detection camera, which makes it easy to adjust the detection distance and fill light distance.
[0037] Reference Figure 3 and Figure 5 A screw is threadedly connected to the slide 202, and one end of the screw is extended into the slide 202 and abutted against the side wall of the slide rail 201, and a knob is fixedly provided on the end of the screw away from the slide 202. When in use, the screw is driven to rotate by the knob. When the screw is away from the slide rail 201, the slide 202 can be driven to slide on the slide rail 201. When the screw abuts against the slide rail 201, the slide 202 is fixed in the current position, which is convenient to adjust and reliable to fix.
[0038] Reference Figure 3 A limit block is fixedly provided on the working surface of the slide rail 201, and a limit groove matching the limit block is opened on the sliding surface of the slide 202. The limit block is T-shaped or dovetail-shaped. Here, we prefer a T-shape, and the limit groove is slidably connected to the limit block, and one end of the screw rod extended into the limit groove is against the side wall of the limit block. When in use, by fixing the limit block on the slide rail 201 and opening a limit groove matching the limit block on the slide 202, not only can the slide 202 be guaranteed to slide reliably, but also the slide 202 can be prevented from sliding in the direction perpendicular to the sliding direction, affecting normal use.
[0039] Reference Figure 3-Figure 5 A fixed frame 501 is rotatably provided at the execution end of the robot arm 5, and a servo motor for driving the fixed frame 501 to rotate is fixedly provided at the execution end of the robot arm 5. A cylinder is fixedly provided at the end of the fixed frame 501 away from the robot arm 5. The rotation angle of the fixed frame 501 is 0-360 degrees. After driving the bottle body to rotate one circle, it will rotate back to its original position, which can reduce the number of winding circles of the air supply pipe and facilitate air supply. A pneumatic clamp 502 is fixedly provided at the output end of the cylinder for clamping the bottle mouth. When in use, by rotatably setting the fixed frame 501 on the robot arm 5, when the front camera 3 is performing inspection, the bottle body can be driven to rotate for inspection, thereby increasing the inspection range, and a pneumatic clamp 502 is fixedly provided at the output end of the cylinder, which is convenient for grabbing products on the inspection conveyor line and improving the use effect.
[0040] Reference Figure 1 and Figure 3Here, the inspection conveyor line includes a product conveyor line and a discharge bin 10. The discharge bin 10 is used to discharge defective products. The product conveyor line includes a first conveyor rack 101 and a second conveyor rack 102 fixedly arranged in the inspection box 1. The first conveyor rack 101 and the second conveyor rack 102 are respectively rotatably provided with a feed conveyor belt and a discharge conveyor belt. When in use, the bottle body can be placed on the feed conveyor belt for transportation, which is convenient for the top camera 2 to detect. After the inspection is completed, the robot arm 5 grabs the bottle body on the feed conveyor belt. When the product passes the inspection again, the robot arm 5 will place the product on the discharge conveyor belt for transfer. In addition, the first conveyor rack 101 and the second conveyor rack 102 are fixedly provided with a holding plate, which is respectively located on both sides of the first conveyor rack 101 and the second conveyor rack 102. The holding plates can limit and guide the bottle body when conveying the bottle body to prevent it from slipping.
[0041] Reference Figure 1 and Figure 3 , the first conveyor rack 101 and the second conveyor rack 102 are respectively located on both sides of the arch fill light 7, the product conveying direction of the feed conveyor belt and the unloading conveyor belt is parallel to the axis of the front camera 3, and the top camera 2 is located above the feed conveyor belt. When in use, by locating the first conveyor rack 101 and the second conveyor rack 102 on both sides of the arch fill light 7, not only can the product loading and qualified products be placed separately to reduce the mixing phenomenon, but also on both sides of the arch fill light 7, that is, on both sides of the robot arm 5, it helps to reduce the size and transfer distance of the robot arm 5, thereby improving the user experience.
[0042] Reference Figure 3 and Figure 6The feed port of the discharge bin 10 is located between the outer wall of the arch fill light 7 and the inner wall of the first conveyor frame 101, and a buffer net 11 with a cylindrical structure is provided in the discharge bin 10. A first fixing ring 12 and a third fixing ring 14 are fixedly provided at both ends of the buffer net 11. A second fixing ring 13 is fixedly provided on the buffer net 11. The second fixing ring 13 is located between the first fixing ring 12 and the third fixing ring 14. At this time, the line connecting the centers of the first fixing ring 12, the second fixing ring 13 and the third fixing ring 14 is an arc structure, and the inner diameter of the first fixing ring 12 is larger than the inner diameter of the second fixing ring 13 and the third fixing ring 14. The inner diameter of the second fixing ring 13 is equal to the inner diameter of the third fixing ring 14, that is, the buffer net 11 is an arc-shaped structure, and the outlet is toward the outlet of the discharge bin 10. The outer walls of the first fixing ring 12, the second fixing ring 13 and the third fixing ring 14 are fixedly arranged in the discharge bin 10. When in use, when the defective products are put into the discharge bin 10 by the robot arm 5, the bottle body will fall into the buffer net 11, and the bottle body will be discharged downward along the arc of the buffer net 11. At this time, the buffer net 11 can cushion the fall of the bottle body to prevent the bottle body from falling directly into the discharge bin 10, which can reduce the damage to the bottle body and the discharge bin 10 and improve the use effect.
