Description

Technical Field

[0001] The present invention relates to the technical field of airport luggage disinfection, and more particularly to an automatic disinfection device for an airport luggage claim carousel. Background Art

[0002] The automatic disinfection device for the airport baggage claim carousel is a disinfection device suitable for airport disinfection operations. It is mainly used for luggage disinfection to avoid the spread of pathogens due to untimely luggage disinfection.

[0003] Currently, airport baggage handling systems primarily utilize two operational modes for end-of-line disinfection: manual disinfection and automated disinfection. Manual disinfection relies on operators using handheld spray devices to disinfect the baggage surface, posing occupational exposure risks and inefficient operations. Mainstream automated disinfection devices typically consist of a high-pressure atomizing spray system, a UV irradiation module, and a conveyor mechanism. Their core configuration includes a matrix atomizing nozzle array and four parallel sets of 30W UV lamps, which spray vertically downward to perform disinfection operations. However, existing technical solutions still have the following significant drawbacks: 1. Manual disinfection carries systemic risks: Operators are exposed to potential contamination sources at close range, and the physical isolation provided by protective equipment is limited, posing a risk of viral transmission. Furthermore, manual operation is limited by the operator's physical strength and attention span, making it difficult to maintain consistent disinfection quality and efficiency. 2. Automated disinfection devices suffer from structural design flaws: Existing equipment is typically mounted above the baggage claim carousel. The effective range between the vertical spray pattern and the baggage is limited by the height of luggage of varying sizes (which requires maintaining a safe distance), resulting in a reduced deposition of the atomized disinfectant. More critically, complex structural areas such as the luggage compartment's side handle slots and handle grooves are not effectively covered. These areas are high-risk areas for pathogens to accumulate, creating a weak link in epidemic prevention. 3. Equipment maintenance blind spots affect disinfection reliability: Existing spray systems use a fixed layout, unable to dynamically adjust the angle based on the luggage's shape and lack a blockage self-detection function. When the nozzles experience atomization abnormalities or partial blockage due to long-term use, this directly creates a disinfection blind spot. The fault point is difficult to detect promptly through routine inspections, leading to the risk of continuous disinfection failure. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic disinfection device for an airport baggage claim carousel to solve the problems existing in the above-mentioned background technology.

DETAILED DESCRIPTION

[0025] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The automatic disinfection device for an airport baggage claim carousel involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1 and Figure 4 The present invention provides an automatic disinfection device for an airport baggage claim carousel, comprising a disinfection device 2, a baggage conveyor belt 1 being provided at the bottom end of the disinfection device 2, a disinfectant storage tank 3 being provided at the top of the disinfection device 2, a liquid injection port 4 being provided at the top of the disinfection device 2, a bottom plate 5 being provided inside the disinfection device 2, a moving ring 6 being provided at the top of the bottom plate 5, a support ring 7 being fixedly connected to the top of the bottom plate 5, a disinfection ring 8 being provided at the top of the support ring 7, and a liquid supply ring 9 being provided at the top of the disinfection ring 8.

[0027] By adjusting the height of the entire device through the base plate 5, the coordinated positioning of the motion ring 6 and the disinfection ring 8 in three-dimensional space can be achieved. When the system starts the disinfection program, it first accurately identifies the three-dimensional outline of the suitcase through the laser sensor, and then the base plate 5 moves smoothly down from the initial reference plane along the vertical guide rail to the side of the box. During this process, the motion ring 6 driven by the positioning motor 57 will move along the preset trajectory to the side of the box, and its end effector will be accurately aligned with the reference line of the lower edge of the handle through the visual positioning system to establish an ideal workstation for subsequent operations. At the same time, the disinfection ring 8 rotates synchronously under the drive of the disinfection drive motor 71, and its 100 micron-level atomizing nozzles distributed in a ring array can form a 360° surround disinfection curtain wall, and cooperate with the Z-axis positioning function of the base plate 5 to achieve full-wrapped three-dimensional disinfection from the bottom to the top of the box (height coverage range 600-1200mm).

[0028] Reference Figure 2 and Figure 6 The top of the base plate 5 is fixedly connected to a threaded ring 51, a threaded rod 54 is provided in the middle of the threaded ring 51, and a stepping motor 55 is fixedly connected to the top of the threaded rod 54. The top of the base plate 5 is fixedly connected to a guide ring 52, a guide rod 53 is provided in the middle of the guide ring 52, and an annular positioning slide rail 58 is provided on the top of the base plate 5. The side of the base plate 5 is fixedly connected to a fixed plate 56, and the top of the fixed plate 56 is fixedly connected to a positioning motor 57.

[0029] Through a high-precision closed-loop control system, the trapezoidal threaded rod 54 is driven by a stepper motor 55 to perform precise rotational motion. The transmission mechanism can convert rotational motion into axial linear displacement, driving the threaded ring 51 to achieve precise vertical displacement. The threaded ring assembly is linked to the base plate 5 of the load-bearing platform through a rigid connection mechanism. Under the drive of the control system, it can realize intelligent vertical positioning based on the three-dimensional data feedback from the luggage size detection module, so that the positioning ring 6 can achieve high-precision movement under the drive of the positioning motor 57, thereby coping with suitcases placed at different angles on the baggage claim carousel, improving the equipment's adaptability to suitcases of different sizes, and greatly improving the efficiency of disinfection work, fully meeting the stringent requirements of modern airport smart logistics systems for efficient disinfection equipment.

[0030] Reference Figure 6 There are two stepper motors 55, diagonally located on either side of the bottom surface of the top of the disinfection device 2. There are two threaded rods 54, two threaded rings 51, two guide rods 53, and two guide rings 52. The two threaded rods 54 drive the bottom plate to move up and down, while the two guide rods 53 are located at opposite corners of the bottom plate 5, so that the bottom plate 5 can only move up and down, improving the operating accuracy when lifting the luggage handle.

[0031] Reference Figure 6 and Figure 8A guide block 61 is provided around the moving ring 6, and a support frame 64 is fixedly connected to the gap between the four guide blocks 61. A telescopic motor 62 is provided on the side of the guide block 61, and a horizontal threaded rod 63 is provided on the end face of the telescopic motor 62. A shift block 65 is provided on the end face of the horizontal threaded rod 63, and a slider 66 is provided on the side of the shift block 65. A slide groove 67 is provided inside the guide block 61, and a positioning slider 68 is fixedly connected to the bottom end of the guide block 61.

[0032] During the rotational positioning stage, the positioning slider 68 located at the bottom end of the guide block 61 cooperates with the slide rail 58, and the servo positioning motor 57 with an encoder drives the motion ring 6 through the harmonic reducer to adjust the angle. The rotating mechanism is equipped with an electronic limit protection device, which is controlled by PLC programming to ensure that the rotation angle of the motion ring 6 is strictly limited to the preset safety range, which not only meets the handle position adaptation requirements of suitcases of different specifications, but also effectively prevents mechanical interference with the telescopic motor 62.

[0033] Once the motion ring 6 completes angular calibration, the horizontal telescopic module is activated. A stepper telescopic motor 62, mounted on the side of the guide block 61, drives a threaded rod 63 through a coupling, which in turn drives a shift block 65 with a built-in ball nut for axial displacement. To ensure motion stability, sliders 66 are symmetrically positioned on either side of the shift block 65. These, combined with rectangular grooves 67 machined inside the guide block by a grinder, form a dual-guiding mechanism, enhancing linear motion repeatability.

[0034] Reference Figure 7 A disinfection drive motor 71 is provided at the top of the support ring 7, and the disinfection drive motor 71 provides the power required for the disinfection ring 8 to rotate.

[0035] Reference Figure 7 and Figure 8The bottom side of the disinfection ring 8 is provided with a pulley 81, a disinfectant tank 84 is provided inside the disinfection ring 8, a spray ring 82 is provided at the top of the disinfection ring 8, and a disinfection nozzle 83 is provided on the inside of the spray ring 82. The disinfection ring 8 contacts the support ring 7 through the pulley 81 and reduces the resistance of the disinfection ring 8 when it rotates during operation. The disinfectant tank 84 inside the disinfection ring 8 is used to store the disinfectant required during operation, which solves the problem of disinfectant supply caused by the rotating device provided. The disinfectant is transported to the spray ring 82 through the disinfection tank 84 and is evenly sprayed through the disinfection nozzle 83 on the spray ring 82. At the same time, the disinfection ring 8 is constantly rotating, thereby forming a dense disinfectant in the internal area of ​​the disinfection ring 8 and adhering to the surface of the luggage case and the gap between the handles, thereby improving the coverage rate of the disinfectant on the luggage case and achieving a more ideal disinfection effect. A plurality of disinfection nozzles 83 are arranged on the inner side of the spray ring 82. When working, the spray ring 82 is in a rotating state. When one or several disinfection nozzles 83 are blocked or damaged, the other disinfection nozzles 83 can still form dense disinfectant in the internal area of ​​the disinfection ring 8, avoiding the disinfection blind spot caused by the blockage or damage of the disinfection nozzles 83, improving the disinfection quality, avoiding maintenance shutdown, and improving work efficiency.

[0036] Reference Figure 7 The bottom end of the liquid supply ring 9 is provided with a liquid supply nozzle 91, and there are four liquid supply nozzles 91. The top of the liquid supply ring 9 is fixedly connected to the top of the disinfection device 2. The disinfectant is transported to the liquid supply ring through the disinfectant storage tank 3. When the disinfection operation is completed and the disinfectant needs to be replenished, the bottom plate 5 returns to the initial position under the action of the stepping motor 55. At this time, the liquid supply ring 9 is located directly above the disinfectant tank 84. The liquid supply nozzle 91 extends into the disinfectant tank 84 under the rising action of the bottom plate 5 to replenish the disinfectant inside.

[0037] The working principle of the present invention is as follows: when the luggage is in operation, the luggage is placed on the luggage conveyor belt 1 and transported so that the luggage enters the interior of the disinfection device and is located below the center of the moving ring 6. The threaded rod 54 is driven by the stepping motor 55, and the threaded rod 54 cooperates with the fixing ring 51 with internal threads, so that the bottom plate 5 moves downward along the guide rod 53 to the lower part of the handle in the middle of the luggage. The positioning mechanism 6 is driven by the positioning motor 57 so that the shift block 65 is aligned with the handle on the side of the luggage. The positioning mechanism 6 is limited by the positioning motor 57 so that the positioning mechanism 6 is only in the position where the luggage is located. It rotates at a certain angle, and the telescopic motor 62 drives the horizontal threaded rod 63, so that the shift block 65 extends toward the suitcase to the lower part of the suitcase handle, and the stepping motor 55 drives the threaded rod 54 to rotate, so that the bottom plate 5 moves upward, and then the shift block 65 lifts the suitcase handle, and is driven by the disinfection drive motor 71 on the support ring 7 to rotate the disinfection ring 8, and the disinfection liquid stored in the disinfection liquid tank 84 passes through the spray ring 82, so that the disinfection nozzle 83 sprays the disinfectant, and then the disinfectant is evenly sprayed around the suitcase and in the gap between the handle and the suitcase.

[0038] At the end of the work, the disinfectant is sprayed, and the disinfection drive motor 71 on the support ring 7 stops driving, so that the disinfection ring 8 stops rotating, and the threaded rod 54 is driven by the stepper motor 55. At the same time, the threaded rod 54 cooperates with the fixed ring 51 with an internal thread, so that the bottom plate 5 moves downward to a certain position along the guide rod 53, thereby causing the suitcase handle to fall. The horizontal threaded rod 63 is driven by the telescopic motor 62, so that the shift block 65 moves back to its original position away from the suitcase. The threaded rod 54 is driven by the stepper motor 55. At the same time, the threaded rod 54 cooperates with the fixed ring 51 with an internal thread, so that the bottom plate 5 moves upward to the initial position along the guide rod 53, thereby preparing for the next disinfection work. It is transported through the luggage conveyor belt 1, so that the disinfected suitcase moves out of the disinfection device, completing a disinfection work.

[0039] When the disinfectant needs to be replenished, the disinfectant is transported to the liquid supply ring 9 at the lower end through the disinfectant storage tank 3 , so that the liquid supply nozzle 91 replenishes the disinfectant into the annular disinfectant tank 84 .
