Description

Technical Field

[0001] The present invention relates to the technical field of detection instruments, and in particular to a device for detecting foreign matter in a bottle. Background Art

[0002] Glass bottle foreign body inspection is a key step in ensuring that the interior of the container is free of impurities and foreign matter, and is crucial for maintaining product quality and protecting consumer safety. For example, for products such as finished bird's nests, which are glass-bottled foods containing pre-cooked bird's nests, the bottle should not contain difficult-to-remove contamination such as rust, oil stains, or water marks. Furthermore, the interior of the bird's nest product should be free of foreign matter such as black specks, bird feathers, plastic, hair, insects, fibers, and glass fragments. The presence of these foreign objects not only affects the appearance and taste of the product, but also poses a potential risk to consumer health.

[0003] The current inspection process typically involves continuously conveying glass bottles into the inspection area via conveyor equipment, where they are scanned using front-mounted laser vision inspection equipment, with information subsequently collected by a data acquisition module. However, this approach has limitations. Because the inspection equipment detects the bottle from the front, the curved shape of the glass bottle can easily create overlapping areas on both sides of the bottle. This prevents the sides from being fully illuminated by the laser, making it difficult to fully inspect the product inside the bottle, resulting in incomplete data collection and insufficient accuracy. Furthermore, the relatively simple conveyor structure in existing equipment makes the bottles prone to shaking during subsequent inspection, further affecting the accuracy of the test data.

[0004] Therefore, in view of the above-mentioned problems, it is urgent to propose a foreign body detection device in the bottle that can ensure all-round and stable detection of the bottle body, overcome the detection blind spot caused by the shape of the glass bottle, and reduce the measurement error caused by the movement of the bottle, so as to more effectively ensure the quality of bottled products containing finished bird's nests, thereby further protecting the health and safety of consumers. Summary of the Invention

[0009] Laser collectors are arranged on the rotating ring at intervals along the circumference, and a placement frame is also arranged circumferentially on the outer periphery of the rotating ring in accordance with the number and layout of the laser collectors;

[0010] The retaining ring is provided on the machine base, with a notch on one side of the retaining ring. A contact ring is slidably and intermittently provided on the rotating ring in a circumferential direction for contact with the retaining ring. The contact ring has the same layout as the placement frame. A set of inclined guide rails are provided on both sides of the contact ring. A vertical frame is slidably provided on the guide rail, and the vertical frame is slidably connected to the corresponding placement frame. A clamping roller for fixing the bottle is rotated between the two ends of the vertical frame, and an elastic member is provided between the vertical frame and the inner wall of the corresponding placement frame.

[0011] The gear ring is set on the machine base and is arranged concentrically with the retaining ring. A large gear 1 and a reduction gear connected coaxially are set at the bottom of each placement frame. The large gear 1 is engaged with the gear ring. A large gear 2 engaged with the reduction gear is also set at the bottom of the placement frame. A turnover plate is also coaxially connected to the large gear 2, and the turnover plate is rotatably embedded in the bottom of the placement frame.

[0012] Optionally, the driving turntable includes a fixed-frame motor arranged in the base, and a connecting frame connected to the output end of the fixed-frame motor is rotatably arranged in the middle of the top of the base, and the outer periphery of the connecting frame is connected to the rotating ring.

[0013] Optionally, the speed ratio of the ring gear to the large gear 1 is 1:8, so that the reduction gear rotates at the same speed and meshes with the large gear 2, and the speed ratio of the reduction gear to the large gear 2 is 8:1.

[0014] Optionally, a small gear is provided at the bottom end of each clamping roller, and the small gear is meshed with the large gear.

[0015] Optionally, it also includes a mounting ring arranged on the top of the machine base, the mounting ring is located on the periphery of the rotating ring, and the mounting ring has an opening that is consistent with the position of the notch of the abutment ring, and a guide frame with an isosceles trapezoidal structure is provided on the top of the mounting ring, the guide frame is located above the opening, and a collection plate is slidably penetrated on each placement frame, the collection plate is electrically connected to the corresponding laser collector, and a protruding rod that contacts and cooperates with the guide frame is provided on the collection plate, and the protruding rod is abutted and adapted to the mounting ring.

[0016] Optionally, it also includes a shielding cover arranged between the peripheries of each placement frame, with a through slot consistent with the layout of the placement frame opened on the shielding cover, and three conveyors installed on the machine base, respectively used for detection and transportation, and conveying and processing of qualified and unqualified bottles.

[0017] Optionally, it further includes limiting plates arranged on both sides of each conveyor for limiting the bottle conveying position.

[0018] Optionally, it also includes two assembly frames arranged on the machine base, the assembly frames are located at the inner ring position of the swivel, and chain drive components are provided in the assembly frames.

[0020] The advantages of the present invention lie in: Multiple laser collectors are circumferentially arranged on the rotating ring, each with a dedicated placement frame to ensure precise positioning of bottles during inspection. Furthermore, the device incorporates an adjustable clamping roller structure, leveraging the collaboration between the back ring and the contact ring for flexible adjustment based on actual needs, ensuring that the bottles remain highly stable throughout the inspection process. Furthermore, the inspection process utilizes a unique combination of a gear ring and a series of precision gears (including a first large gear, a reduction gear, and a second large gear) to achieve precise meshing and a 1:1 overall speed ratio. Consequently, when the first large gear completes a full rotation along the gear ring, it synchronously drives each of the rotating disks to rotate 360 degrees, enabling comprehensive scanning and inspection of bottles placed thereon. This effectively eliminates the issues of side overlap and blind spots caused by the curved surfaces of glass bottles, enabling comprehensive and accurate scanning and analysis of various bottles containing foreign matter. The device is particularly suitable for automated inspection processes, significantly improving the efficiency and accuracy of overall foreign matter detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0034] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0035] Example 1: A device for detecting foreign matter in a bottle, such as Figure 1-Figure 7 As shown, including:

[0036] Base 1 is the main support carrier;

[0037] The driving turntable includes a rotating ring 22 that rotates at the top middle position of the base 1;

[0038] The laser collectors 3 are arranged on the rotating ring 22 at intervals along the circumference. The laser collectors 3 are existing technologies and use a laser beam to scan the target bottle 100. By measuring the distance between the laser beam and the surface of the object, the three-dimensional data of the bottle 100 is obtained, thereby achieving the effect of detecting foreign objects in the bottle. At the same time, to ensure that each bottle 100 can receive stable laser detection, a placement frame 31 with the same number and layout as the laser collectors 3 is also circumferentially arranged on the periphery of the rotating ring 22. The placement frame 31 is provided with a cavity for placing the bottle 100 to be detected, and a groove is opened on the side of the placement frame 31 facing the laser collector 3. The groove is in the same direction as the laser collector 3 at the corresponding position, ensuring that the laser beam can penetrate into the placement frame 31 through the groove, thereby performing foreign object detection on the bottle 100 in the stable space, effectively reducing external interference factors, and ensuring that the detected bottle 100 can be in a relatively fixed and suitable detection position when being scanned, thereby improving the stability of the detection process and the accuracy of the results;

[0039] The butt ring 4 is fixedly arranged on the top of the machine base 1 and is located at the inner ring position of the rotating ring 22. The two are concentrically arranged, and a notch is opened on the front side of the butt ring 4. At the same time, an extended plate body inclined backward is provided on both sides of the notch of the butt ring 4. In addition, the rotating ring 22 is also circumferentially spaced and slidably penetrated with contact rings 41 that contact and cooperate with the butt ring 4. The number and layout of the contact rings 41 are consistent with those of the placement frame 31. The contact ring 41 adopts a U-shaped structure design. With the front view as the main viewing angle, the closed end of the contact ring 41 faces the butt ring 4, and the two side parts of the contact ring 41 are respectively located on one side of the corresponding placement frame 31. When the rotating ring 22 rotates, the contact ring 41 thereon rotates accordingly and contacts with the butt ring 4 in turn. In this process, due to the guiding effect of the extended plate body, the contact ring 4 1 will slide along the inclined surface of the extension plate and move forward on the rotating ring 22, causing the closed end of the contact ring 41 to tightly abut against the main body of the abutting ring 4, providing stable trajectory support for the subsequent clamping operation. A group of guide rails 42 with a rearward tilt distribution are provided on both sides of the contact ring 41. The two guide rails 42 of the same group are arranged in a front-to-back interval. A vertical frame 43 is slidably penetrated on each guide rail 42, and the vertical frame 43 is slidably connected to the corresponding placement frame 31. A clamping roller 44 for fixing the bottle 100 is rotated between the upper and lower ends of the vertical frame 43. The clamping roller 44 is vertically arranged, and an elastic member 45 is provided between the vertical frame 43 and the inner wall of the corresponding placement frame 31. In this embodiment, the elastic member 45 is a spring to provide the necessary elastic force for the vertical frame 43 to reset.

[0040] Specifically, the contact and cooperation between the collar 4 and the contact ring 41 realizes the pushing of the upright frame 43 and the clamping roller 44. When the collar 4 and the contact ring 41 are in contact, the clamping roller 44 is in a clamping state, firmly fixing the bottle 100 during the inspection process in the placement frame 31; on the contrary, when the contact ring 41 reaches the notch of the collar 4, the contact ring 41 is no longer restricted. Then, under the elastic action of the elastic member 45, the clamping rollers 44 and the upright frame 43 on both sides are forced to reset and slide. The inclined guidance of the guide rail 42 causes the clamping rollers 44 and the upright frame 43 on both sides to move away from each other, and the contact ring 41 is pushed back accordingly, thereby releasing the clamping restriction on the bottle 100, restoring the movable state of the bottle 100 after inspection, and allowing it to be subsequently discharged and processed at the notch.

[0041] The gear ring 5 is fixedly mounted on the top of the machine base 1 and is located in the outer area of the retaining ring 4, and the two are concentrically arranged. A notch is provided on the gear ring 5, which is located in the same position as the notch of the retaining ring 4 to ensure the consistency of the stroke. A large gear 1 51 and a reduction gear 52 are coaxially connected at the bottom of the placement frame 31. The reduction gear 52 is located above the large gear 1 51, and the large gear 1 51 is meshed with the gear ring 5. A large gear 2 53 is also provided at the bottom of the placement frame 31, which is meshed with the reduction gear 52. The large gear 2 53 is located directly below the corresponding cavity of the placement frame 31. A turnover disk 54 is also coaxially connected to the large gear 2 53, and the turnover disk 54 is rotatably embedded in the bottom of the placement frame 31.

[0042] Specifically, the speed ratio of the gear ring 5 (excluding the notched portion) to the large gear 1 51 is 1:8. Since the reduction gear 52 is coaxially connected to the large gear 1 51 , the reduction gear 52 maintains the same speed as the large gear 1 51 and meshes with the large gear 2 53 . The speed ratio of the reduction gear 52 and the large gear 2 53 is 8:1, which means that when the large gear 1 51 completes one rotation along the gear ring 5 (excluding the notched part), it will synchronously drive the reduction gear 52 to rotate eight circles. Through the meshing action of the reduction gear 52 and the large gear 2 53, one rotation of the large gear 2 53 is realized in this process. At the same time, the turnover plate 54 coaxially connected to the large gear 2 53 will also synchronously complete a 360-degree rotation, ensuring that the bottle 100 placed thereon can be irradiated by the laser beam of the laser collector 3 in all directions. This design ensures that the rotation speed of the bottle 100 maintains a 1:1 ratio with the operating speed of the device body, thereby effectively overcoming the detection blind spot caused by the shape of the bottle 100. Combined with the fixing effect of the clamping roller 44, the measurement error caused by the movement of the bottle 100 is reduced, thereby improving the accuracy and reliability of the overall detection, and more effectively ensuring product quality.

[0043] like Figure 1-Figure 4As shown, the driving turntable includes a fixed motor 2 arranged in a base 1, and a connecting frame 21 connected to the output end of the fixed motor 2 is rotatably arranged in the middle of the top of the base 1, and the outer periphery of the connecting frame 21 is connected to a rotating ring 22.

[0044] like Figure 6 As shown, the apparatus further includes a small gear 55 disposed at the bottom end of each clamping roller 44. The small gear 55 is engaged with the large gear 2 53, so that when the large gear 2 53 rotates, the small gears 55 are synchronously engaged to drive the clamping roller 44 to rotate, thereby ensuring smooth rotation of the bottle 100 during the inspection process.

[0045] like Figure 1 and Figure 8 As shown, it also includes a mounting ring 6 fixedly arranged on the top of the machine base 1, the mounting ring 6 is located in the outer area of the rotating ring 22, and an opening is opened on the mounting ring 6 that is consistent with the position of the notch of the ring 4. A guide frame 61 with an isosceles trapezoidal structure is provided on the top of the mounting ring 6. The guide frame 61 is located above the opening, and each placement frame 31 is slidably penetrated with a collection plate 62, which coincides with the cavity opening of the placement frame 31, and in order to ensure that the collection plate 62 can be stable when the placement frame 31 is closed, a magnet is embedded in the inner bottom of the placement frame 31. , used to magnetically fix the position of the collection board 62; at the same time, the collection board 62 is electrically connected to the corresponding laser collector 3. The collection board 62 can receive the optical signal returned by the laser collector 3, convert the optical signal into an electrical signal, and perform data preprocessing to ensure that the data signal is transmitted to the control center of gravity of the background. The background analyzes the abnormal changes of the optical signal through the algorithm, and judges whether there is foreign matter inside the bottle 100 based on the image displayed by the detection. A protruding rod 63 that contacts and cooperates with the guide frame 61 is fixed on the upper side of the collection board 62, and the protruding rod 63 is abutted and adapted with the mounting ring 6.

[0046] When in use, the device is first placed on the ground. The clamping rollers 44 at the notch of the collar 4 are released, allowing the bottle 100 containing the bird's nest to be placed inside the frame 31. Meanwhile, the protruding rods 63 at the notch abut against the top of the guide frame 61. The connected collecting plate 62, constrained by the protruding rods 63, remains raised upward, ensuring that the cavity of the frame 31 is open for subsequent placement of the bottle 100.

[0047] Then, the fixed-frame motor 2 is started, and the rotating ring 22 begins to rotate clockwise, driving the placement frames 31 thereon to move one by one to the notch position of the anvil ring 4. Then, the bottle 100 to be inspected can be placed in each placement frame 31 in sequence, so that the bottle 100 is placed on the rotating disk 54. As the rotating ring 22 continues to rotate, the contact ring 41 gradually moves to the end of the notch of the anvil ring 4 and slides in contact with it under the guidance of the inclined surface of the extended plate at the end, and finally tightly abuts against the main body of the anvil ring 4, thereby pushing the contact ring 41 forward as a whole. Under the tilting action of the guide rail 42, the vertical frames 43 on both sides slide toward the center, and the elastic member 45 is deformed accordingly, so that the clamping rollers 44 on both sides are synchronously in contact with the surface of the bottle 100, forming a stable clamping state, thereby fixing the position of the bottle 100 for inspection.

[0048] At the same time, large gear 1 51 on the placement frame 31 rotates synchronously with the rotating ring 22 and meshes with the gear ring 5. Large gear 1 51 rotates, driving the coaxially connected reduction gear 52 to rotate synchronously. Reduction gear 52 further meshes with large gear 2 53, which rotates accordingly and drives the connected turnover plate 54 to rotate, thereby driving the bottle 100 to rotate circumferentially within the placement frame 31. Simultaneously, the corresponding laser collector 3 immediately emits a laser beam, performing a comprehensive 360-degree foreign body inspection on the bottle 100, ensuring the complete detection of the bird's nest inside the bottle. To ensure the natural rotation of the bottle 100, the small gear 55 meshes synchronously with large gear 2 53. The small gear 55 rotates and drives the corresponding clamping roller 44 to rotate, thereby assisting the smooth rotation of the bottle 100 and making its rotation more smooth.

[0049] During operation, as the swivel ring 22 continues to rotate, the protruding rod 63 simultaneously moves downward along the trapezoidal slope of the guide frame 61, driving the acquisition plate 62 downward and closing the placement frame 31, allowing the acquisition plate 62 to complete the detection data collection work in conjunction with the laser collector 3. Simultaneously, the meshing rotation of large gear 1 51 and the gear ring 5 drives large gear 2 53 to complete one rotation, thereby driving the turnover plate 54 and the bottle 100 to synchronously complete a 360-degree rotation, ensuring all-round detection of the bottle 100.

[0050] During the operation of the entire device, the bottle 100 is firmly clamped and rotates smoothly in the placement frame 31. The laser collector 3 scans the inside of the bottle 100 efficiently and accurately, and cooperates with the acquisition board 62 to effectively detect foreign objects in the bottle and quickly collect detection data of built-in foreign objects. This not only achieves stable clamping and all-round detection of the bottle 100, but also significantly improves detection efficiency and accuracy, providing reliable guarantee for product quality.

[0051] Example 2: Based on Example 1, Figure 1 and Figure 9As shown, it also includes a shielding cover 7 arranged between the outer peripheries of each placement frame 31, the shielding cover 7 is located in the inner area of the mounting ring 6, and a through groove 71 consistent with the layout of the placement frame 31 is opened on the shielding cover 7, and three conveyors 72 are installed on the machine base 1, which are respectively used for the transportation of detection products, the transportation processing of qualified products, and the transportation processing of unqualified products.

[0052] Specifically, the shielding cover 7 effectively blocks the gaps between the placement frames 31, ensuring that each bottle 100 to be inspected can be accurately placed into the corresponding placement frame 31 only through the through slots 71, thereby ensuring the stability and accuracy of the feeding process. Furthermore, by providing three sets of dedicated conveyors 72, each providing independent logistics channels for the infeed of inspected products, the discharge of qualified products, and the discharge of unqualified products, this enables automated sorting and processing of the inspected bottles 100, significantly improving production efficiency and significantly enhancing operational convenience.

[0053] like Figure 9 As shown, it also includes limiting plates 73 arranged on both sides of each conveyor 72, which are used to limit the conveying position of the bottle 100 containing the bird's nest.

[0054] like Figure 10 and Figure 11 As shown, it also includes two assembly frames 8 circumferentially arranged on the top of the machine base 1, the two assembly frames 8 are spaced apart, and the assembly frames 8 are located at the inner ring position of the swivel 22, and chain drive components are provided in the assembly frames 8, and a slider 84 that is slidably connected to the corresponding assembly frame 8 is connected to the output member of the chain drive component, and a guide sleeve 85 is symmetrically provided at the front end of the assembly frame 8, and a push rod 86 that slides through the guide sleeve 85 on the same side is provided on the slider 84.

[0055] like Figure 10 and Figure 11 As shown, the chain drive assembly includes a motor 81 installed on one side of each assembly frame 8, and sprockets 82 arranged in a front-to-back spacing rotate in the assembly frame 8. The output end of the motor 81 is connected to the shaft end of the adjacent sprocket 82. A chain 83 is provided between the sprockets 82 in the same assembly frame 8, and the chain 83 is connected to the slider 84 on the same side.

[0056] When the inspected bottle 100 needs to be pushed out, the motor 81 at the corresponding position is started to drive the sprocket 82 to rotate, thereby driving the chain 83 to operate. The movement of the chain 83 drives the slider 84 to slide along the assembly frame 8, and then drives the connected push rod 86 to slide along the guide sleeve 85. The push rod 86 passes through the rotating ring 22, thereby ejecting the inspected bottle 100 and pushing it into the corresponding conveyor 72 (qualified or unqualified) to achieve rapid discharge processing.
