Description

Technical Field

[0001] This invention relates to the field of airport baggage disinfection technology, and more specifically to an automatic disinfection device for airport baggage claim carousels. Background Technology

[0002] The automatic disinfection device at airport baggage claim carousels is a suitable disinfection device for airport disinfection operations. It is mainly used for baggage disinfection to prevent the spread of germs due to untimely baggage disinfection.

[0003] Currently, airport baggage handling systems primarily employ two disinfection methods: manual disinfection and automated equipment disinfection. Manual disinfection relies on personnel using handheld sprayers to disinfect baggage surfaces, posing occupational exposure risks and exhibiting low efficiency. Mainstream automated disinfection devices typically consist of a high-pressure atomizing spray system, an ultraviolet irradiation module, and a conveying mechanism. Their core configuration includes a matrix array of atomizing nozzles and four parallel sets of 30W ultraviolet lamps, performing disinfection through vertical downward spraying. However, current technologies still have the following significant drawbacks: 1. Manual disinfection presents systemic risks: personnel must be in close contact with potential contaminants, and the physical isolation effect of protective equipment is limited, posing a risk of virus transmission through contact. Furthermore, manual operation is limited by personnel's physical strength and attention levels, making it difficult to maintain consistent disinfection quality and processing efficiency; 2. Automated disinfection devices suffer from structural design flaws: existing equipment is typically mounted above the baggage claim carousel, and the effective contact distance between the vertical spray mode and baggage is limited by the passage height of baggage of different sizes (requiring a safe distance), leading to a decrease in the sedimentation effect of the atomized disinfectant. More importantly, complex structural areas such as the pull rod grooves and handle recesses on the sides of the suitcase cannot be effectively covered. These areas are precisely high-risk zones for pathogen retention, creating weak links in epidemic prevention. 3. Equipment maintenance blind spots affect disinfection reliability: The existing spray system uses a fixed layout, which cannot dynamically adjust the angle according to the shape of the luggage and lacks a blockage self-check function. When the nozzles experience atomization abnormalities or local blockages due to long-term use, disinfection blind spots will be directly created, and the fault points are difficult to detect in time 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 airport baggage claim carousels to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: an automatic disinfection device for airport baggage claim carousels, comprising a disinfection device, a baggage conveyor belt at the bottom of the disinfection device, a disinfectant storage tank at the top of the disinfection device, an injection port at the top of the disinfectant storage tank, a base plate inside the disinfection device, a moving ring at the top of the base plate, a support ring fixedly connected to the top of the base plate, a disinfection ring at the top of the support ring, and a liquid supply ring at the top of the disinfection ring.

[0006] Furthermore, a threaded ring is fixedly connected to the top of the base plate, a threaded rod is provided in the middle of the threaded ring, a stepper motor is fixedly connected to the top of the threaded rod, a guide ring is fixedly connected to the top of the base plate, a guide rod is provided in the middle of the guide ring, an annular positioning slide rail is provided on the top of the base plate, a fixing plate is fixedly connected to the side of the base plate, and a positioning motor is fixedly connected to the top of the fixing plate.

[0007] Furthermore, there are two stepper motors, diagonally distributed on both sides of the top bottom surface of the disinfection device; there are two threaded rods; there are two threaded rings; there are two guide rods; and there are two guide rings.

[0008] Furthermore, guide blocks are arranged around the motion ring, and support frames are fixedly connected to the four guide blocks with gaps. A telescopic motor is arranged on the side of the guide block, a horizontal threaded rod is arranged on the end face of the telescopic motor, a lever is arranged on the end face of the horizontal threaded rod, a slider is arranged on the side of the lever, a sliding groove is arranged inside the guide block, and a positioning slider is fixedly connected to the bottom end of the guide block.

[0009] Furthermore, a disinfection drive motor is provided at the top of the support ring.

[0010] Furthermore, a pulley is provided on the bottom side of the disinfection ring, a disinfectant tank is provided inside the disinfection ring, a spray ring is provided on the top of the disinfection ring, and a disinfection nozzle is provided on the inner side of the spray ring.

[0011] Furthermore, the bottom end of the liquid supply ring is provided with a liquid supply nozzle, there are four liquid supply nozzles, and the top end of the liquid supply ring is fixedly connected to the top end of the disinfection device.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention uses a positioning drive motor to drive a moving ring, allowing the ring to rotate along a groove on the base plate within a certain angle. This enables the lever on the moving ring to align with the handle on the side of the suitcase. The lever is located around the perimeter of the moving ring. The positioning drive motor installed on the guide block drives the internal horizontal threaded rod, allowing the lever to extend and retract freely. This allows the suitcase to adapt to different sides and complete corresponding operations, improving the accuracy and precision of handle operation and enhancing the suitcase's adaptability to different positions and directions. Since no adjustment of the suitcase's position is required, the disinfection efficiency of the suitcase is improved.

[0014] 2. This invention uses a disinfection drive motor located on a support ring to drive the disinfection ring, allowing the disinfection ring to rotate on the support ring under the action of the bottom pulley. This, in turn, drives the spray ring at the top of the disinfection ring to rotate, and the disinfection nozzle evenly sprays the disinfectant stored in the disinfectant tank onto the surface of the suitcase, improving the disinfectant spraying efficiency. Together with the fixing ring, it increases the coverage of disinfectant on the surface of the suitcase, enabling more precise disinfection work.

[0015] 3. The present invention uses a supply ring and a disinfection ring located at the bottom of the disinfectant storage tank to cooperate with each other, so that the supply nozzle delivers disinfectant to the disinfectant tank on the disinfection ring. This allows the disinfection ring to be replenished quickly and accurately after it has finished working, without having to stop the machine when it needs to be replenished, thereby improving operating efficiency.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic disinfection device for airport baggage claim carousels involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figure 1 and Figure 4 The present invention provides an automatic disinfection device for airport baggage claim carousel, including a disinfection device 2, a baggage conveyor belt 1 at the bottom of the disinfection device 2, a disinfectant storage tank 3 at the top of the disinfection device 2, an injection port 4 at the top of the disinfectant storage tank 3, a base plate 5 inside the disinfection device 2, a moving ring 6 at the top of the base plate 5, a support ring 7 fixedly connected to the top of the base plate 5, a disinfection ring 8 at the top of the support ring 7, and a liquid supply ring 9 at the top of the disinfection ring 8.

[0028] By adjusting the height of the entire device using the base plate 5, the motion ring 6 and the disinfection ring 8 can be coordinated in three-dimensional space. When the system starts the disinfection program, the three-dimensional outline of the suitcase is first accurately identified by a laser sensor. Then, the base plate 5 moves smoothly from the initial reference plane along the vertical guide rail to the side of the suitcase. During this process, the motion ring 6, driven by the positioning motor 57, moves along a preset trajectory to the side of the suitcase. Its end effector is precisely aligned with the lower edge of the handle reference line through a visual positioning system, establishing an ideal working position for subsequent operations. At the same time, the disinfection ring 8 rotates synchronously under the drive of the disinfection drive motor 71. Its 100 micron-level atomizing nozzles distributed in a ring array can form a 360° surround disinfection curtain. Combined with the Z-axis positioning function of the base plate 5, it achieves full-coverage three-dimensional disinfection from the bottom to the top of the suitcase (height coverage range 600-1200mm).

[0029] Reference Figure 2 and Figure 6 A threaded ring 51 is fixedly connected to the top of the base plate 5. A threaded rod 54 is provided in the middle of the threaded ring 51. A stepper motor 55 is fixedly connected to the top of the threaded rod 54. A guide ring 52 is fixedly connected to the top of the base plate 5. A guide rod 53 is provided in the middle of the guide ring 52. An annular positioning slide rail 58 is provided on the top of the base plate 5. A fixing plate 56 is fixedly connected to the side of the base plate 5. A positioning motor 57 is fixedly connected to the top of the fixing plate 56.

[0030] A high-precision closed-loop control system drives a stepper motor 55 to precisely rotate a trapezoidal threaded rod 54. This transmission mechanism converts the 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 support platform via a rigid connection mechanism. Driven by the control system, it can achieve intelligent vertical positioning based on the three-dimensional data fed back by the baggage size detection module. This allows the positioning ring 6 to move with high precision under the drive of the positioning motor 57, thus accommodating suitcases placed at different angles on the baggage claim carousel. This improves the equipment's adaptability to suitcases of different sizes, significantly increasing disinfection efficiency and fully meeting the stringent requirements of modern airport smart logistics systems for high-efficiency disinfection equipment.

[0031] Reference Figure 6 There are two stepper motors 55, diagonally distributed on both sides of the top bottom surface 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 base plate to move up and down, while the two guide rods 53 are located diagonally opposite the base plate 5, so that the base plate 5 can only move up and down, improving the operational accuracy when lifting the suitcase handle.

[0032] Reference Figure 6 and Figure 8A guide block 61 is provided around the motion ring 6. A support frame 64 is fixedly connected to the four guide blocks 61 with gaps. A telescopic motor 62 is provided on the side of the guide block 61. A horizontal threaded rod 63 is provided on the end face of the telescopic motor 62. A lever 65 is provided on the end face of the horizontal threaded rod 63. A slider 66 is provided on the side of the lever 65. A sliding groove 67 is provided inside the guide block 61. A positioning slider 68 is fixedly connected to the bottom end of the guide block 61.

[0033] During the rotation positioning stage, the positioning slider 68 located at the bottom of the guide block 61 cooperates with the slide rail 58. The servo positioning motor 57 with encoder drives the motion ring 6 to adjust the angle through a harmonic reducer. The rotation mechanism is equipped with an electronic limit protection device. Through PLC programming control, it ensures that the rotation angle of the motion ring 6 is strictly limited within the preset safety range, which not only meets the adaptive requirements of the handle position of different sizes of suitcases, but also effectively prevents mechanical interference with the telescopic motor 62.

[0034] Once the motion ring 6 completes angle calibration, the horizontal telescopic module is activated. The stepper telescopic motor 62, located on the side of the guide block 61, drives the threaded rod 63 via a coupling, causing the paddle block 65 with its built-in ball nut to move axially. To ensure motion stability, sliders 66 are symmetrically arranged on both sides of the paddle block 65, forming a double guiding mechanism with the rectangular groove 67 precision-machined inside the guide block, thus improving the repeatability and positioning accuracy of linear motion.

[0035] Reference Figure 7 The top of the support ring 7 is equipped with a disinfection drive motor 71, which provides the power required for the rotation of the disinfection ring 8.

[0036] Reference Figure 7 and Figure 8The disinfection ring 8 has a pulley 81 at its bottom side, a disinfectant tank 84 inside, and a spray ring 82 at its top. A disinfection nozzle 83 is located on the inner side of the spray ring 82. The disinfection ring 8 contacts the support ring 7 via the pulley 81, reducing resistance during rotation. The disinfectant tank 84 inside the disinfection ring 8 stores the disinfectant needed for operation, solving the disinfectant supply problem caused by the rotating device. The disinfectant is delivered to the spray ring 82 through the disinfectant tank 84 and sprayed evenly through the disinfection nozzle 83 on the spray ring 82. Simultaneously, the disinfection ring 8 rotates continuously, forming a dense layer of disinfectant inside the ring and adhering to the surface of the suitcase and the gaps in the handles, improving the disinfectant coverage and achieving a more ideal disinfection effect. Multiple disinfection nozzles 83 are provided inside the spray ring 82. During operation, the spray ring 82 is in a rotating state. When one or more disinfection nozzles 83 become blocked or damaged, the other disinfection nozzles 83 can still form a dense disinfectant solution in the inner area of ​​the disinfection ring 82. This avoids blind spots in disinfection caused by blockage or damage of the disinfection nozzles 83, improves disinfection quality, avoids downtime for maintenance, and improves work efficiency.

[0037] Reference Figure 7 The bottom end of the liquid supply ring 9 is provided with liquid supply nozzles 91, and there are four liquid supply nozzles 91. The top end of the liquid supply ring 9 is fixedly connected to the top end of the disinfection device 2. The disinfectant is delivered into the liquid supply ring through the disinfectant storage tank 3. When the disinfection operation is completed and the disinfectant needs to be replenished, the base plate 5 returns to the initial position under the action of the stepper motor 55. At this time, the liquid supply ring 9 is located directly above the disinfectant tank 84. The liquid supply nozzles 91 extend into the disinfectant tank 84 under the rising action of the base plate 5 to replenish the disinfectant inside.

[0038] The working principle of this invention is as follows: During operation, the suitcase is placed on the luggage conveyor belt 1 and transported into the disinfection equipment. Simultaneously, the suitcase is positioned below the center of the moving ring 6. A stepper motor 55 drives a threaded rod 54, which engages with a threaded fixing ring 51. This causes the base plate 5 to move downwards along the guide rod 53 to the lower part of the handle in the middle of the suitcase. A positioning motor 57 drives a positioning mechanism 6, aligning the lever 65 with the handle on the side of the suitcase. The positioning motor 57 limits the movement of the positioning mechanism 6 only when... The lever 65 extends into the luggage compartment to the bottom of the luggage handle by rotating at a certain angle. The stepper motor 55 drives the threaded rod 54 to rotate, causing the base plate 5 to move upward. This causes the lever 65 to lift the luggage handle. The disinfection drive motor 71 on the support ring 7 drives the disinfection ring 8 to rotate. The disinfection solution stored in the disinfection tank 84 passes through the spray ring 82, causing the disinfection nozzle 83 to spray out the disinfection solution, which is then evenly sprayed around the luggage compartment and in the gap between the handle and the luggage compartment.

[0039] When the work is finished, the disinfectant spraying is completed. The disinfection drive motor 71 on the support ring 7 stops driving, causing the disinfection ring 8 to stop rotating. The stepper motor 55 drives the threaded rod 54, which engages with the threaded fixing ring 51, causing the base plate 5 to move downward along the guide rod 53, thus lowering the suitcase handle. The telescopic motor 62 drives the horizontal threaded rod 63, causing the lever 65 to move away from the suitcase and back to its initial position. The stepper motor 55 drives the threaded rod 54, which engages with the threaded fixing ring 51, causing the base plate 5 to move upward along the guide rod 53 back to its initial position, thus preparing for the next disinfection operation. The disinfected suitcase is then transported out of the disinfection device by the luggage conveyor belt 1, completing one disinfection operation.

[0040] When the disinfectant needs to be replenished, the disinfectant is delivered to the lower end of the supply ring 9 through the disinfectant storage tank 3, so that the supply nozzle 91 replenishes the disinfectant into the annular disinfectant tank 84.
