Description

Technical Field

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

[0002] The detection of foreign objects in glass bottles is a crucial step in ensuring that the interior of the container is free of impurities and foreign objects, and is essential for maintaining product quality and protecting consumer safety. For example, for products such as ready-to-eat bird's nest in glass bottles, there should be no difficult-to-remove contaminants such as rust, oil stains or water marks on the bottle, and at the same time, the interior of the bird's nest product should not contain foreign objects such as black spots, bird feathers, plastics, hairs, insects, fibers and glass fragments. The presence of these foreign objects not only affects the appearance and taste of the product, but may also pose potential risks to the health of consumers.

[0003] The current detection process usually involves continuously feeding glass bottles into the detection area through a transmission device and using a front-mounted laser vision detection device for scanning, and then collecting information by a data acquisition module. However, this method has certain limitations. Since the detection device detects the bottle body from the front, affected by the arc shape of the glass bottle, overlapping areas are easily formed on both sides of the bottle body, resulting in the side edges not being completely irradiated by the laser, making it difficult to fully detect the product inside the bottle, causing problems of incomplete data collection and insufficient accuracy. In addition, the transmission structure in the existing device is relatively simple, which makes the bottle shake easily when entering subsequent detections, further affecting the accuracy of the detection data.

[0004] Therefore, in view of the above existing problems, it is urgently necessary to propose a device for detecting foreign objects in a bottle that can ensure all-round and stable detection of the bottle body, overcome the detection blind area 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 guarantee the quality of bottled products containing ready-to-eat bird's nest, and further protect the health and safety of consumers. Summary of the Invention

[0005] In order to overcome the above-mentioned disadvantages of the prior art, the present invention provides a device for detecting foreign objects in a bottle that can ensure all-round and stable detection of the bottle body.

[0006] The technical solution is as follows: A device for detecting foreign objects in a bottle, comprising: A machine base; A driving turntable, the driving turntable includes a rotating ring rotating on the machine base; A laser collector, circumferentially arranged at intervals on the rotating ring, and a placement frame is also circumferentially arranged on the periphery of the rotating ring, which is consistent with the number and layout of the laser collectors; The abutting ring is arranged on the machine base. An opening is formed on one side of the abutting ring. A contact ring which is in contact and cooperation with the abutting ring is slidably and circumferentially arranged on the rotating ring at intervals. The contact ring has the same layout as the placing frame. A group of inclined guide rails are arranged on both sides of the contact ring. A vertical frame is slidably arranged on the guide rails, and the vertical frame is slidably connected with the corresponding placing frame. A clamping roller for fixing the bottle is rotatably arranged between the two ends of the vertical frame, and an elastic member is arranged between the vertical frame and the inner wall of the corresponding placing frame; The toothed ring is arranged on the machine base and is concentrically arranged with the abutting ring. A large gear one and a reduction gear are coaxially connected at the bottom of each placing frame. The large gear one is meshed with the toothed ring. A large gear two which is meshed with the reduction gear is also arranged at the bottom of the placing frame. A turnover disk is coaxially connected to the large gear two. The turnover disk is rotatably embedded in the inner bottom of the placing frame.

[0007] Optionally, the driving turntable includes a fixed-positioning motor arranged in the machine base. A connecting frame connected to the output end of the fixed-positioning motor is rotatably arranged in the middle of the top of the machine base. The periphery of the connecting frame is connected to the rotating ring.

[0008] Optionally, the speed ratio of the toothed ring to the large gear one is 1:8, so that the reduction gear rotates at the same speed and meshes with the large gear two, and the speed ratio of the reduction gear to the large gear two is 8:1.

[0009] Optionally, it further includes a small gear arranged at the bottom end of each clamping roller. The small gear is meshed with the large gear two.

[0010] Optionally, it further includes a mounting ring arranged on the top of the machine base. The mounting ring is located outside the rotating ring, and the mounting ring is provided with an opening at the same position as the opening of the abutting ring. A guiding frame in an isosceles trapezoid structure is arranged on the top of the mounting ring. The guiding frame is located above the opening. A collecting plate is slidably arranged on each placing frame. The collecting plate is electrically connected to the corresponding laser collector. A convex rod which is in contact and cooperation with the guiding frame is arranged on the collecting plate, and the convex rod is in abutting fit with the mounting ring.

[0011] Optionally, it further includes a shielding cover arranged between the peripheries of each placing frame. The shielding cover is provided with through grooves with the same layout as the placing frame. Three conveyors are arranged on the machine base, which are respectively used for detection and conveying, and the conveying and processing of qualified and unqualified bottles.

[0012] Optionally, it further includes limiting plates arranged on both sides of each conveyor, which are used to limit the conveying position of the bottles.

[0013] Optionally, it further includes two assembly frames arranged on the machine base. The assembly frames are located inside the rotating ring. Chain drive assemblies are arranged in the assembly frames. A slider slidably connected with the corresponding assembly frame is connected to the output member of the chain drive assembly. Guide sleeves are symmetrically arranged at the front end of the assembly frame. A push rod slidably passing through the guide sleeve on the same side is arranged on the slider.

[0014] Optionally, the chain drive assembly includes motors installed on one side of each assembly frame. In the assembly frame, sprockets are rotatably arranged with a front-back spaced layout.

[0015] The advantages of the present invention are as follows: By circumferentially arranging a plurality of laser collectors on the swivel ring and designing a special placement frame for each collector to accurately position the bottle during detection; in addition, the device also introduces an adjustable clamping roller structure, which utilizes the cooperation between the abutting ring and the contact ring to flexibly adjust according to actual needs to ensure that the bottle remains highly stable throughout the detection process. At the same time, a unique combination of a toothed ring and a series of precision gears (including the first large gear, the reduction gear, and the second large gear) is particularly adopted in the detection process to achieve precise meshing operation and achieve a total speed ratio control of 1:1. In this way, when the first large gear completes a full rotation along the toothed ring, it can synchronously drive each turntable to rotate 360 degrees, enabling the bottle placed on it to be scanned and detected from all angles, effectively solving the problems of side overlap and detection blind spots caused by the arc surface of the glass bottle, so as to comprehensively and accurately scan and analyze various bottled products containing foreign objects, especially suitable for automated detection processes, greatly improving the overall foreign object detection efficiency and accuracy.

[0029] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment 1: A device for detecting foreign objects in a bottle, as Figures 1 - 7 shown, includes: Machine base 1, which is the main support carrier; Drive turntable, the drive turntable includes a swivel ring 22 that rotates at the middle position on the top of the machine base 1; The laser collector 3 is circumferentially and spacedly arranged on the rotating ring 22. The laser collector 3 is a prior art device that scans the target bottle 100 with a laser beam and obtains the three-dimensional data of the bottle 100 by measuring the distance between the laser beam and the object surface, thereby achieving the effect of detecting foreign objects inside the bottle. At the same time, to ensure that each bottle 100 can be stably detected by laser, a placement frame 31 with the same quantity and layout as the laser collector 3 is also circumferentially arranged outside 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 oriented in the same direction as the corresponding laser collector 3, ensuring that the laser beam can shine into the interior of the placement frame 31 through the groove, thereby detecting foreign objects in the bottle 100 in a stable space, effectively reducing external interference factors, and at the same time ensuring that the bottle 100 to be detected can be in a relatively fixed and suitable detection position during scanning, improving the stability of the detection process and the accuracy of the results; The abutting ring 4 is fixedly arranged at the top of the machine base 1 and is located inside the inner ring of the rotating ring 22, and the two are concentrically arranged. An opening is provided at the front side of the abutting ring 4. At the same time, extension plate bodies that tilt backward are arranged at both end parts of the opening of the abutting ring 4. The rotating ring 22 is also circumferentially and spacedly slidably penetrated with a contact ring 41 that is in contact and cooperation with the abutting ring 4. The contact ring 41 has the same quantity and layout as the placement frame 31. The contact ring 41 is designed with a U-shaped structure. Taking the front view as the main perspective, the closed end of the contact ring 41 faces the abutting 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 and sequentially contacts the abutting ring 4. During this process, due to the guiding action of the extension plate body, the contact ring 41 will slide along the inclined surface of the extension plate body 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 subsequent clamping operations. A set of guide rails 42 that are inclined backward are arranged on both sides of the contact ring 41. The two guide rails 42 in the same group are arranged at intervals in the front-back direction. A vertical frame 43 is slidably penetrated on each of the guide rails 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 rotatably arranged between the upper and lower ends of the vertical frame 43. The clamping roller 44 is vertically arranged, and an elastic member 45 is arranged 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, providing the necessary elastic force for the vertical frame 43 to return to its original position; Specifically, through the contact fit between the abutting ring 4 and the contact ring 41, the pushing of the opposing frame 43 and the clamping rollers 44 is realized. When the abutting ring 4 abuts against the contact ring 41, the clamping rollers 44 are in a clamping state of approaching, firmly fixing the bottle 100 during the detection process in the placement frame 31; on the contrary, when the contact ring 41 reaches the notch of the abutting ring 4, the contact ring 41 is no longer restricted, and then under the elastic action of the elastic member 45, the clamping rollers 44 and the opposing frame 43 on both sides are caused to slide back in place. Using the inclined guiding of the guide rail 42, the clamping rollers 44 and the opposing frame 43 on both sides move away from each other, and the contact ring 41 is pushed backward accordingly, thereby releasing the clamping restriction on the bottle 100 to restore the moving state of the bottle 100 after detection, enabling it to perform subsequent discharging and other processes at the notch.

[0031] The toothed ring 5 is fixedly arranged on the top of the machine base 1 and is located in the peripheral area of the abutting ring 4, and the two are concentrically arranged. The toothed ring 5 is provided with a notch that is consistent with the notch position of the abutting ring 4 to ensure the consistency of the stroke. A large gear one 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 one 51, and the large gear one 51 meshes with the toothed ring 5. A large gear two 53 that meshes with the reduction gear 52 is also arranged at the bottom of the placement frame 31. The large gear two 53 is located directly below the corresponding cavity of the placement frame 31. A turntable 54 is coaxially connected to the large gear two 53, and the turntable 54 is rotatably embedded in the inner bottom of the placement frame 31.

[0032] Specifically, the speed ratio of the toothed ring 5 (excluding the notch part) to the large gear one 51 is 1:8. Since the reduction gear 52 is coaxially connected to the large gear one 51, the reduction gear 52 maintains the same rotation speed as the large gear one 51 and meshes with the large gear two 53. The speed ratio of the reduction gear 52 to the large gear two 53 is 8:1, which means that when the large gear one 51 rotates one full circle along the toothed ring 5 (excluding the notch part), it will synchronously drive the reduction gear 52 to make eight revolutions. Through the meshing action of the reduction gear 52 and the large gear two 53, during this process, one full rotation of the large gear two 53 is achieved, and at the same time, the turntable 54 coaxially connected to the large gear two 53 will also complete a 360-degree rotation synchronously, ensuring that the laser beam of the laser collector 3 can irradiate the bottle 100 placed on it from all directions. This design ensures that the rotation speed of the bottle 100 is in a 1:1 ratio with the operating speed of the device main body, thereby effectively overcoming the detection blind area caused by the shape of the bottle 100. Combining with the fixing effect of the clamping rollers 44, the measurement error caused by the movement of the bottle 100 is reduced together, improving the overall detection accuracy and reliability, and more effectively ensuring the product quality.

[0033] Such as Figures 1 - 4As shown in the figure, the driving turntable includes a stop motor 2 arranged in the machine base 1. In the middle of the top of the machine base 1, a connecting frame 21 connected to the output end of the stop motor 2 is rotatably arranged, and the periphery of the connecting frame 21 is connected to a rotating ring 22.

[0034] As Figure 6 shown in the figure, it further includes small gears 55 arranged at the bottom ends of the respective clamping rollers 44. The small gears 55 are meshed with the second large gear 53, so that when the second large gear 53 rotates, it synchronously meshes with and acts on the respective small gears 55 to drive the clamping rollers 44 to rotate, thereby ensuring the smooth rotation of the bottle 100 during the detection process.

[0035] As Figure 1 and Figure 8 shown in the figure, it further includes a mounting ring 6 fixedly arranged on the top of the machine base 1. The mounting ring 6 is located in the peripheral area of the rotating ring 22, and an opening consistent with the notch position of the abutting ring 4 is formed on the mounting ring 6. A guiding frame 61 with an isosceles trapezoid structure is arranged on the top of the mounting ring 6. The guiding frame 61 is located above the opening, and a collecting plate 62 is slidably penetrated through each placing frame 31. The collecting plate 62 coincides with the cavity opening of the placing frame 31. And to ensure that the collecting plate 62 can be stable when closing the placing frame 31, a magnet is embedded in the inner bottom of the placing frame 31 for magnetically attracting and fixing the position of the collecting plate 62; meanwhile, the collecting plate 62 is electrically connected to the corresponding laser collector 3. The collecting plate 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 in the background. The background analyzes the abnormal changes of the optical signal through an algorithm and judges whether there are foreign objects inside the bottle 100 according to the detected image. A convex rod 63 in contact and cooperation with the guiding frame 61 is fixedly arranged on the upper side of the collecting plate 62, and the convex rod 63 is in abutting fit with the mounting ring 6.

[0036] During use, first place the device stably on the ground. At this time, the clamping roller 44 at the notch of the abutting ring 4 is in a released state, so as to place the test bottle 100 loaded with bird's nest inside the placing frame 31. At the same time, the convex rod 63 at the notch abuts against the top of the guiding frame 61, and the connected collecting plate 62 is always in an upwardly lifted state due to the restriction of the convex rod 63, thereby ensuring that the cavity opening of the placing frame 31 is opened for subsequent placement operations of the bottle 100.

[0037] Then the fixed frame motor 2 is started, the rotating ring 22 starts to rotate clockwise, driving the placement frames 31 thereon to move to the notch position of the ring 4 one by one, and then the bottles 100 to be tested can be placed in each placement frame 31 in turn, so that the bottles 100 are 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 ring 4, and slides in contact under the guidance of the inclined surface of the plate extending from the end, and finally tightly abuts against the main body of the ring 4, thereby pushing the contact ring 41 forward as a whole. Under the tilting action of the guide rail 42, the stand 43 on both sides slide close to the middle, and the elastic member 45 is deformed accordingly, so that the clamping rollers 44 on both sides are synchronously fitted to the surface of the bottle 100, forming a stable clamping state, thereby fixing the position of the bottle 100 for testing.

[0038] At the same time, the large gear 1 51 on the placement frame 31 rotates with the rotating ring 22 and meshes with the gear ring 5 synchronously. The large gear 1 51 rotates and drives the coaxially connected reduction gear 52 to rotate synchronously. The reduction gear 52 further meshes with the large gear 2 53, and the large gear 2 53 rotates and drives the connected turnover plate 54 to rotate, thereby driving the bottle 100 to rotate circumferentially in the placement frame 31. At the same time, the corresponding laser collector 3 immediately emits a laser beam to perform a 360-degree comprehensive foreign body detection on the bottle 100 to ensure the complete detection of the bird's nest in the bottle. In order to ensure the natural rotation of the bottle 100, the small gear 55 meshes with the large gear 2 53 synchronously, and 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 smoother.

[0039] During operation, as the rotating ring 22 continues to rotate, the protruding rod 63 will synchronously move down along the trapezoidal slope of the guide frame 61, driving the collection plate 62 to slide down and close the placement frame 31, so that the collection plate 62 cooperates with the laser collector 3 to complete the collection of detection data. At the same time, through the meshing rotation of the large gear 1 51 and the gear ring 5, the large gear 2 53 is driven to complete a rotation, thereby driving the revolving plate 54 and the bottle 100 to synchronously complete a 360-degree rotation, ensuring all-round detection of the bottle 100.

[0040] 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 performs efficient and accurate scanning on the inside of the bottle 100, and cooperates with the acquisition board 62 to effectively detect foreign objects in the bottle and quickly collect the 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 the detection efficiency and accuracy, providing reliable guarantee for product quality.

[0041] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 9As shown, it further includes a shielding cover 7 disposed between the peripheries of each placement frame 31. The shielding cover 7 is located in the inner peripheral area of the mounting ring 6, and through slots 71 consistent with the layout of the placement frames 31 are formed in the shielding cover 7. Three conveyors 72 are installed on the machine base 1, respectively used for detecting the conveyance of products, the conveyance and processing of qualified products, and the conveyance and processing of unqualified products.

[0042] Specifically, the shielding cover 7 can effectively shield the intervals between the placement frames 31, ensuring that each bottle 100 to be detected can only be accurately placed into the corresponding placement frame 31 through the through slots 71, thereby ensuring the stability and accuracy of the feeding process. Moreover, by setting three sets of conveyors 72 with specific purposes, independent logistics channels are provided for the feeding of detected products, the discharging of qualified products, and the discharging of unqualified products respectively, realizing the automatic classification and processing of the bottles 100 after detection, greatly improving the production efficiency and significantly enhancing the convenience of operation.

[0043] As Figure 9 shown, it further includes limit plates 73 disposed on both sides of each conveyor 72, used to limit the conveyance position of the bottles 100 containing bird's nest.

[0044] As Figure 10 and Figure 11 shown, it further 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 rotating ring 22. Chain drive assemblies are arranged in the assembly frames 8. A slider 84 slidably connected to the corresponding assembly frame 8 is connected to the output member of the chain drive assembly. Guide sleeves 85 are symmetrically arranged at the front end of the assembly frame 8. A push rod 86 slidably passing through the guide sleeve 85 on the same side is arranged on the slider 84.

[0045] As Figure 10 and Figure 11 shown, the chain drive assembly includes a motor 81 installed on one side of each assembly frame 8. In the assembly frame 8, sprockets 82 are rotatably arranged with a front - and - rear spaced layout. The output end of the motor 81 is connected to the shaft end of the adjacent sprocket 82. A chain 83 is arranged between the sprockets 82 in the same assembly frame 8, and the chain 83 is connected to the slider 84 on the same side.

[0046] When it is necessary to push out the detected bottles 100, 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 pushes 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 then passes through the rotating ring 22, thereby pushing out the detected bottles 100 and pushing them into the corresponding conveyor 72 (qualified or unqualified), realizing rapid discharging processing.

[0047] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be construed in any way as a limitation on the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific implementation manners of the embodiments of the present invention without creative efforts, and these manners will all fall within the protection scope of the embodiments of the present invention.
