Description

Technical Field

[0001] This invention relates to the field of food conveying and detection devices, specifically to an industrial-scale intelligent scanning device for the conveying and detection of ready-to-eat foods. Background Technology

[0002] In recent years, with the rapid development of computer vision, artificial intelligence and Internet of Things technologies, intelligent detection technologies have been gradually applied to the industrial production field. These technologies can achieve rapid and comprehensive detection of food, improving production efficiency and quality control.

[0003] Currently, on canned food production lines, when conveying finished canned goods to the packaging station using conveyor equipment, the cameras used for image acquisition have certain limitations. Due to the limitations of the camera's acquisition angle and field of view, blind spots may appear in the captured images, making it impossible to comprehensively and accurately detect key indicators such as the appearance quality, label position and integrity of the canned food, thus affecting the control of product quality.

[0004] Furthermore, canned foods typically undergo heat treatment during processing and are subsequently sealed to ensure their shelf life and safety. However, existing airtightness testing methods mostly employ non-destructive testing techniques, such as vacuum testing, pressure testing, and ultrasonic testing. While these methods can effectively assess the airtightness of canned foods, they are difficult to simultaneously measure the airtightness of canned foods while acquiring images, resulting in a cumbersome and inefficient testing process. Therefore, this paper proposes an intelligent scanning detection device for the conveying of ready-to-eat foods for industrial production. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent scanning detection device for ready-to-eat food conveying in industrial production. It has the advantages of avoiding blind spots in image acquisition and simultaneously detecting the sealing performance of canned food, thus solving the problems of blind spots in image acquisition and difficulty in simultaneously measuring the sealing performance of canned food.

[0010] The central shaft passes through the I-shaped seat and is coaxially fixed with a worm gear. Below the worm gear are two sets of arc-shaped clamping plates that move synchronously in opposite directions or in opposite directions in the horizontal direction. When the two sets of arc-shaped clamping plates reach the end position of the stroke, they rotate synchronously with the worm gear.

[0011] The opposing surfaces of the two sets of arc-shaped clamps are in contact with the outer surface of the food can.

[0012] Preferably, the shaft rotation assembly further includes multiple sets of mounting brackets fixedly connected to the I-shaped base, with a worm gear rotating on the mounting bracket and meshing with the worm. A fixed swing rod is coaxially fixed on the worm gear.

[0014] The end of the crank away from the fixed swing arm includes an integrally formed end plate, and an arc-shaped clamp is disposed on the end plate.

[0015] Preferably, the end plate has a rectangular groove for sliding connection of the arc-shaped clamping plate, and a relief spring is provided in the rectangular groove. The two ends of the relief spring are respectively fixedly connected to the arc-shaped clamping plate and the end plate.

[0017] Preferably, the positioning disk has multiple sets of receiving grooves arranged in a circular array on the side facing the I-shaped base. Each set of receiving grooves is slidably connected with a resistance block, and a compression spring is provided in the receiving groove. The two ends of the compression spring are respectively fixedly connected to the positioning disk and the resistance block.

[0018] The resistance block and the I-shaped seat are in frictional contact with each other on their opposite surfaces.

[0019] Preferably, the pendulum assembly includes a top cylinder that rotates on the upper frame and is connected to the central shaft via a transmission.

[0020] The threaded directional groove includes an integrally formed vertical straight groove section.

[0021] Preferably, the upper connecting rod has a middle connecting rod that rotates on a fixed axis at its bottom end.

The image processing algorithm performs real-time detection and analysis of the appearance features of the canned food, and the data processing module is also electrically connected to a terminal module.

[0025] The data processing module includes a communication module for transmitting detection signals to the terminal module. The communication module transmits the detection results to the terminal module in a structured data format.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 9The present invention provides a technical solution: an industrial production intelligent scanning ready-to-eat food conveying and detection device, including a conveying device 1 for conveying food cans and a base frame set on it, a camera module 2 for collecting image information on the base frame, and a torsion measuring mechanism for preventing image acquisition blind spots and measuring the sealing performance of food cans on the base frame.

[0041] The torsion measuring mechanism includes an upper frame 3 fixedly connected to the base frame, a lower frame 4 rotating on the upper frame 3, a positioning plate 5 fixedly connected to the lower frame 4, and a shaft rotation assembly on the positioning plate 5 for clamping and fixing the food can and driving the food can to rotate after fixing.

[0042] A V-shaped seat 20 is fixedly connected to the upper frame 3. The V-shaped seat 20 is equipped with a pendulum component that drives the shaft rotation assembly to run and drives the lower frame 4 and the positioning disk 5 to swing synchronously.

[0043] During the conveying and inspection of canned food, the movement of the canned food is achieved by starting and stopping the conveyor device 1. When a single canned food moves to the position of the rotating assembly, the image information of the canned food at that position can be captured by the camera module 2 set on one side of the base frame. In order to avoid blind spots in image acquisition, the canned food is clamped and fixed by the rotating assembly, and after clamping and fixing, the canned food is driven to rotate in the horizontal direction. By rotating the canned food within the image acquisition area, a comprehensive image acquisition process of the canned food is achieved. Thus, the camera module 2 can gradually capture images of various sides of the canned food to evaluate the production quality of the canned food, including appearance, color, and label integrity.

[0044] Meanwhile, driven by the pendulum component, the shaft rotation component is driven to operate, and after the horizontal rotation of the food can is completed, the lower frame 4 and the positioning plate 5 are driven to deflect at a certain angle in the vertical direction. The top of the can is sealed with a lid. By deflecting the food can, it is tilted at a certain angle, and the camera module 2 collects the image information of the food can in real time. It can also make a preliminary judgment on the sealing of the food can by whether there is a leakage problem in the can, and issue a terminal warning when a sealing problem or quality problem occurs.

[0045] In one preferred embodiment, the shaft rotation assembly includes a central shaft 7 that rotates on a positioning disk 5. The end of the positioning disk 5 away from the lower frame 4 is provided with an I-shaped seat 6 and has a circular cavity groove for sliding connection of the I-shaped seat 6. The central shaft 7 rotates on the I-shaped seat 6.

[0046] The central shaft 7 passes through the I-shaped seat 6 and is coaxially fixed with the worm gear 10. Below the worm gear 10 are two sets of arc-shaped clamping plates 17 that move synchronously in opposite directions or in opposite directions in the horizontal direction. When the two sets of arc-shaped clamping plates 17 reach the end position of the stroke, they rotate synchronously with the worm gear 10.

[0047] The opposing surfaces of the two sets of arc-shaped clamps 17 are in contact with the outer surface of the food can.

[0048] The shaft rotation assembly also includes multiple sets of mounting brackets 15 fixedly connected to the I-shaped base 6. A worm gear 11 is fixedly rotated on the mounting bracket 15, and the worm gear 11 is meshed with the worm 10. A fixed swing rod 12 is coaxially fixed on the worm gear 11.

[0049] The fixed pendulum rod 12 has a fixed axis rotating crank rod 13, and a positioning rod 14 is fixed axis rotating at the middle position of the crank rod 13. The end of the positioning rod 14 away from the crank rod 13 is fixed axis rotating on the mounting frame 15. The end of the crank rod 13 away from the fixed pendulum rod 12 includes an integrally formed end plate portion 131, and an arc-shaped clamping plate 17 is disposed on the end plate portion 131.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, when the central shaft 7 rotates, it can drive the worm gear 10, which is fixed coaxially with it, to rotate synchronously. In the initial state, the horizontal distance between the two sets of arc-shaped clamping plates 17 is the largest. Under the drive of the conveying device 1, the food can can move between the two sets of arc-shaped clamping plates 17. Then, when the worm gear 10 rotates, it can first drive the two sets of arc-shaped clamping plates 17 to move synchronously towards each other, that is, both move synchronously towards the side of the food can and finally stick tightly to the outer surface of the food can.

[0051] Specifically, when the worm 10 rotates with the central shaft 7, it can drive the worm wheel 11 meshing with it to rotate synchronously. The fixed pendulum rod 12 and the crank rod 13, which are coaxially fixed on the worm wheel 11, are rotatably connected. The fixed pendulum rod 12 is provided with a positioning rod 14 at the middle position to limit its position. Thus, during the deflection of the fixed pendulum rod 12, the crank rod 13 can be driven to swing synchronously and change the position of the end plate portion 131 integrally formed at its end, thereby driving the two sets of arc-shaped clamping plates 17 to move synchronously towards or away from each other.

[0052] When both sets of arc-shaped clamps 17 are tightly attached to the outer surface of the food can, the shaft rotation assembly completes the purpose of clamping and fixing the can. Under the restriction of the can, the two sets of arc-shaped clamps 17 cannot continue to move towards each other. As a result, when the central shaft 7 rotates, it can drive the I-shaped seat 6 to rotate on the positioning plate 5 and drive the clamped and fixed can to move synchronously. The image acquisition direction of the camera module 2 is towards one side of the can, thereby driving the can to rotate within the image acquisition area to achieve comprehensive acquisition of the image of the can and the food inside.

[0053] It should be noted that the position of camera module 2 remains unchanged. By driving the tank to rotate, and through comparison and analysis of images from multiple angles, misjudgments caused by shooting from a single angle can be reduced. For example, certain shadows or reflections may be mistaken for defects from a single angle, but by using images from multiple angles, it is possible to more accurately determine whether they are real defects.

[0054] Only after the two arc-shaped clamping plates 17 clamp and fix the tank will the I-shaped seat 6 be driven to rotate on the positioning plate 5 under the restriction of the tank. Therefore, the shaft rotation assembly can adapt to tanks of different diameters, that is, it can drive tanks of different sizes to complete the purpose of clamping and then rotating.

[0055] Furthermore, a stop rod 16 is fixedly connected to the I-shaped base 6 to abut against the fixed pendulum rod 12 to limit the deflection of the fixed pendulum rod 12. After the test is completed and the tank is released, the central shaft 7 rotates in the opposite direction, which in turn drives the worm gear 10 to rotate in the opposite direction, thereby driving the two sets of arc-shaped clamps 17 to move in opposite directions until the fixed pendulum rod 12 abuts against the stop rod 16. At this time, the fixed pendulum rod 12 reaches the maximum deflection state, and then the two sets of arc-shaped clamps 17 return to the initial state, thereby completing the release of the tank.

[0056] Meanwhile, the continuous rotation of the central shaft 7 can drive the I-shaped seat 6 to flip on the positioning plate 5 to realize the reset process of the upper frame 3 and its components. After the components are reset, the position of multiple cans is changed by the conveying device 1 to carry out the image acquisition and detection process of the subsequent food cans.

[0057] Furthermore, a rectangular groove is provided on the end plate 131 for sliding connection of the arc-shaped clamping plate 17. A relief spring 18 is provided in the rectangular groove, and the two ends of the relief spring 18 are fixedly connected to the arc-shaped clamping plate 17 and the end plate 131 respectively.

[0058] The positioning disk 5 is provided with multiple sets of receiving grooves arranged in a ring array on the side facing the I-shaped base 6. Each set of receiving grooves is slidably connected with a resistance block 9, and a pressure spring 8 is provided in the receiving groove. The two ends of the pressure spring 8 are respectively fixedly connected to the positioning disk 5 and the resistance block 9.

[0059] The opposing surfaces of the resistance block 9 and the I-shaped seat 6 are in frictional contact.

[0060] like Figure 5 , Figure 6 and Figure 8 As shown, when the central shaft 7 initially rotates, due to the contact of multiple sets of resistance blocks 9, the sliding friction between the compression spring 8 and the I-shaped seat 6 is relatively large. As a result, when the central shaft 7 drives the worm gear 10 to rotate, the worm wheel 11 can rotate first, thereby completing the purpose of clamping, fixing or releasing the tank.

[0061] Subsequently, when the distance between the two sets of arc-shaped clamps 17 is restricted by the tank or the stop rod 16 and cannot continue to change, the subsequent rotation of the central shaft 7 can drive the I-shaped seat 6 to rotate on the positioning plate 5, thereby driving the tank to rotate synchronously after the tank is clamped and fixed, thus changing the image acquisition range, or driving the upper frame 3 and its components to reset after the tank is released.

[0062] It should be noted that the arc-shaped clamp 17 can make a small displacement on the end plate 131. When the lower frame 4 and the positioning disk 5 are deflected in the vertical direction under the drive of the pendulum assembly, the center point of deflection is the rotation point of both the upper frame 3 and the lower frame 4. Furthermore, when the clamped and fixed tank is driven to swing synchronously, in order to avoid the presence of the conveying device 1 from hindering the swinging process of the tank, a rectangular groove for the arc-shaped clamp 17 to slide is opened on the end plate 131 to accommodate the distance difference caused by the swinging process, thereby ensuring that the tank can follow the lower frame 4 and the positioning disk 5 to deflect synchronously.

[0063] Based on the shaft rotation assembly embodiment, the fixed pendulum assembly includes a top cylinder 19 that rotates on the upper frame 3 and is connected to the central shaft 7 via transmission. The top cylinder 19 is provided with an upper connecting rod 21 that is driven by an electric push rod to move freely up and down on the side facing the V-shaped seat 20. The upper connecting rod 21 is fixedly connected to an adjusting pin 28 on the side facing the top cylinder 19. The top cylinder 19 is provided with a threaded adjusting groove 29 for sliding connection of the adjusting pin 28. The threaded adjusting groove 29 includes an integrally formed vertical straight groove portion 291.

[0064] The upper connecting rod 21 has a fixed axis at its bottom and a middle connecting rod 22. The upper connecting rod 21 and the middle connecting rod 22 are respectively fixedly connected to an upper pin 23 and a lower pin 24 at their ends facing the V-shaped seat 20. The V-shaped seat 20 is provided with a V-shaped guide groove 25 for sliding connection of the upper pin 23 and the lower pin 24.

[0065] The positioning disk 5 has a fixed axis rotating lower connecting rod 26. The end of the lower connecting rod 26 away from the positioning disk 5 is fixedly connected to a corresponding pin 27. The middle connecting rod 22 has a groove for the corresponding pin 27 to slide. The V-shaped guide groove 25 includes an integrally formed inclined groove 251.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the upper connecting rod 21 is driven to move freely in the vertical direction by an electric actuator fixedly mounted on the base frame. The upward pin 23 and downward pin 24 fixedly mounted on the upper connecting rod 21 and the middle connecting rod 22 are slidably mounted on the V-shaped guide groove 25. Thus, when the upper connecting rod 21 initially descends, the upper connecting rod 21 and the middle connecting rod 22 descend synchronously and always remain in a vertical state.

[0067] Furthermore, at this time, the corresponding pin 27 provided on the lower connecting rod 26 slides on the middle connecting rod 22, so the lower connecting rod 26 will not deflect as the upper connecting rod 21 descends. At the same time, when the adjusting pin 28 initially descends, the adjusting pin 28 fixedly provided on it slides on the threaded adjusting groove 29, thereby driving the top cylinder 19 to rotate in the horizontal direction.

[0068] The top cylinder 19 is connected to the central shaft 7 via a universal coupling. When the top cylinder 19 rotates, it can drive the central shaft 7 to rotate synchronously, thereby driving the shaft rotation assembly to operate. It should be noted that under the drive of the universal coupling, when the included angle between the upper frame 3 and the lower frame 4 changes, the rotation process of the top cylinder 19 can still be effectively transmitted to the central shaft 7, thus ensuring that the two can always rotate synchronously.

[0069] Meanwhile, as the upper connecting rod 21 descends, its directional pin 28 slides at the vertical straight groove 291, causing the top cylinder 19 and the central shaft 7 to stop rotating. At the same time, the subsequent lower pin 24 slides on the inclined groove 251 during descent, thereby driving the middle connecting rod 22 to deflect relative to the upper connecting rod 21. When the middle connecting rod 22 deflects, the position of the end away from the upper connecting rod 21 changes, which allows the lower connecting rod 26 to drive the positioning plate 5 and the lower frame 4 to swing at a certain angle in the vertical direction. Then, the camera module 2 captures the image of the can and determines whether leakage occurs to assess the sealing performance of the food can.

[0070] Based on the fixed pendulum component embodiment, the camera module 2 is electrically connected to a data processing module. The data processing module includes an image processing algorithm for recognizing and analyzing the appearance of the image. The image processing algorithm performs real-time detection and analysis of the appearance features of the canned food. The data processing module is also electrically connected to a terminal module.

[0071] The data processing module includes a communication module for transmitting detection signals to the terminal module. The communication module transmits the detection results to the terminal module in a structured data format. The terminal module receives and parses the detection signals transmitted by the communication module.

[0072] like Figure 1As shown, camera module 2 captures images of the covered area and transmits the captured image information to data processing module. Data processing module receives the image data transmitted from camera module 2 and analyzes and processes the image using its internal image processing algorithms (such as deep learning algorithms, edge detection algorithms, etc.). Among them, the image processing algorithm identifies the appearance characteristics of the food can and determines whether the food can has quality problems (such as non-standard size, surface defects, abnormal color, or incomplete label, etc.).

[0073] The data processing module generates a test report based on the image analysis results, including information such as whether the food is qualified and a description of specific problems. The test results are stored in the form of digital signals, usually in a structured data format, and are transmitted to the terminal module through the communication module. The communication module can use wired or wireless communication. At the same time, the terminal module receives the test results from the data processing module and can trigger an alarm mechanism (such as audible and visual alarms, pop-up prompts) when it detects a problem with the food, notifying the operator to take appropriate measures.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
