Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of AGV automatic running vehicles, in particular to an AGV automatic running vehicle for medical supplies. BACKGROUND

[0002] In the modern medical system, efficient and safe transfer of medical supplies is of great importance. AGV automatic running vehicles have been widely used in the transfer of medical supplies due to their automation and flexibility, etc. for transferring large-volume medical supplies, such as the patent announcement No. CN212291498U AGV intelligent identification running vehicle based on RFID, which comprises a vehicle body base, a vehicle-mounted storage rack and a gantry type linear module are arranged on the vehicle body base, the gantry linear module comprises two Z-direction synchronous belt linear modules, a rotating shaft, a first motor, and two couplings; the two Z-direction synchronous belt linear modules are vertically fixed on the vehicle body base, the rotating shaft is connected with the top of the two Z-direction synchronous belt linear modules through the couplings at both ends, and the first motor is arranged at one end of the rotating shaft; a first sliding block is arranged on the Z-direction synchronous belt linear module; a Y-direction synchronous belt linear module is connected with the Z-direction synchronous belt linear module through the first sliding block; a second sliding block is arranged on the Y-direction synchronous belt linear module, and a second motor is arranged on one end of the Y-direction synchronous belt linear module.

[0003] However, the above-mentioned AGV vehicle directly extracts the medical supplies for transfer, which exposes the medical supplies completely. For those medical supplies with strict temperature requirements, especially those that need to be kept at low temperature, the low temperature will continuously spread out during the transfer process. For example, some biological agents, vaccines, etc. need to be stored in a specific low-temperature environment to maintain their activity and quality. However, the existing transfer method causes the temperature to gradually rise, and once it exceeds the specified temperature range, the performance of these medical supplies will be affected, and even lose their effectiveness, which not only causes waste of resources, but also may have serious consequences for medical treatment. In order to minimize the impact of temperature rise, the existing AGV vehicle can only speed up the transfer speed, but this puts higher requirements on the transfer efficiency and stability, and increases the difficulty of transfer. Therefore, the present application designs an AGV automatic running vehicle for medical supplies to delay the temperature rise of medical supplies and ensure stable transfer of the AGV vehicle. SUMMARY

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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.

[0021] like Figures 1 to 14 As shown, an AGV (Automated Guided Vehicle) for medical supplies includes a placement platform 1, a walking component 3 below the placement platform 1, a control console 2 fixedly installed on one side of the placement platform 1, a lifting component 4 for storing supplies on the other side of the placement platform 1, and a protective component 5 for protecting the supplies fixedly installed in the middle of the placement platform 1.

[0022] In this embodiment, the walking component 3 includes four omnidirectional wheels 303, which are respectively installed at the four corners of the lower surface of the placement platform 1. Gearboxes 304 are fixedly installed on both sides of the lower surface of the placement platform 1. A drive motor 305 is installed on the input end of the gearbox 304, and a drive wheel 306 is fixedly installed on the output end of the gearbox 304. A first vision sensor 307 is fixedly installed at the center of the lower surface of the placement platform 1. The first vision sensor 307 can be used in conjunction with the guide strips set in the site to limit the movement route of the AGV vehicle of this application, ensuring that the AGV vehicle moves along the prescribed route.

[0023] Among them, anti-collision beams 301 are fixedly installed at both ends of the lower surface of the placement platform 1, and side plates 302 are fixedly installed on both sides of the lower surface of the placement platform 1. The anti-collision beams 301 are closer to the universal wheel 303, and the side plates 302 are closer to the drive wheel 306.

[0024] The drive motor 305 drives the drive wheel 306 to rotate via the gearbox 304, and the four casters 303 move the placement platform 1 to meet the needs of material transfer. Two drive wheels 306 are located on each side, allowing the angle of the placement platform 1 to be adjusted by controlling the drive direction and speed of the two drive motors 305. This enables the application to rotate by the speed difference and direction between the two drive wheels 306, thus facilitating transfer in any direction. The anti-collision beam 301 and side plates 302 prevent the drive wheels 306 and casters 303 from external impacts. Infrared sensors can be installed on the surfaces of the anti-collision beam 301 and side plates 302 to monitor the distance between the application and external objects to prevent collisions. This structure allows for 360° angular displacement, enabling precise delivery of medical supplies to the required location.

[0025] In this application, the lifting assembly 4 includes a base 401, a shrinkage groove 4011 is provided inside the base 401, a movable plate 407 is movably arranged inside the shrinkage groove 4011, and a support tray 402 is fixedly installed on the upper end of the movable plate 407 by a number of connecting columns 406.

[0026] In the specific setup, a fixed frame 408 is fixedly installed at the bottom of the shrinkage groove 4011. Three mating screw sleeves 4081 are provided on the surface of the fixed frame 408. Three rotating screws 4072 are rotatably installed on the body of the movable plate 407. The body of the rotating screw 4072 is threadedly engaged with the mating screw sleeves 4081.

[0027] It should be noted that a right-angle geared motor 4075 is fixedly installed on the lower surface of the movable plate 407, and a transmission gear 4074 is rotatably installed on one side of the movable plate 407. The output end of the right-angle geared motor 4075 is fixedly connected to the lower end of the transmission gear 4074. Driven gears 4073 are fixedly installed on the upper ends of the three rotating lead screws 4072 respectively. A synchronous gear 4071 is rotatably installed at the center of the upper surface of the movable plate 407. The outer side of the synchronous gear 4071 meshes with the three driven gears 4073 and the transmission gear 4074 respectively.

[0028] By activating the right-angle geared motor 4075, the transmission gear 4074 is driven to rotate. Under the meshing of the synchronous gear 4071 and the transmission gear 4074, the synchronous gear 4071 rotates and drives the three driven gears 4073, causing the three rotating screws 4072 to rotate within the movable plate 407. Under the rotation of the rotating screws 4072, the screws 4072 and the threaded engagement of the mating screw sleeve 4081 are used to drive the movable plate 407 to move up and down in height. This allows the support tray 402 of this application to move to the lower side of the material rack. Then, by activating the right-angle geared motor 4075, the support tray 402 is raised, and the materials are automatically lifted to the upper side for quick storage. Similarly, the right-angle geared motor 4075 rotates in the opposite direction, causing the support tray 402 to descend, and the material rack is lowered to the ground, separating the material from the application and enabling quick unloading. Through the above structure, this application can automatically load and unload materials, reducing personnel intervention, reducing workload, and improving efficiency during loading and unloading.

[0029] The support tray 402 has semiconductor cooling plates 403 on both sides of its upper surface, several heat sinks 405 on its lower surface, and a second vision sensor 404 in the middle of its upper surface.

[0030] By activating the semiconductor cooling plate 403, the temperature above the semiconductor cooling plate 403 is reduced, thereby lowering the temperature of the loaded medical supplies and preventing the temperature of the supplies from rising during transportation and affecting the drugs. Furthermore, several heat sinks 405 are provided on the underside of the support tray 402 to dissipate the heat generated below the semiconductor cooling plate 403 in a timely manner, preventing heat accumulation in the semiconductor cooling plate 403. The second vision sensor 404 can identify whether the supplies are loaded onto the support tray 402 and whether the supplies have detached from the support tray 402, so as to control the start and stop of the right-angle geared motor 4075.

[0031] The lifting component 4 can automatically load and unload medical supplies, thereby reducing direct contact between personnel and the application. This not only reduces the workload of operators but also reduces the chance of contamination between supplies and personnel. Furthermore, it can actively cool down the medical supplies, further slowing down the temperature rise and facilitating the automatic transfer of medical supplies.

[0032] In this application, the protective component 5 includes a bearing housing 501, which is fixedly installed on both sides of the upper surface of the mounting platform 1. A flipping shaft 502 is rotatably installed inside the bearing housing 501. A storage seat 5021 is rotatably mounted on the shaft of the flipping shaft 502, and a flexible film roll 5022 is placed inside the storage seat 5021. A flipping rod 503 is installed at each end of the flipping shaft 502. A docking frame 505 is fixedly installed at one end of the flipping rod 503, and a winding shaft 5052 is installed between the two docking frames 505. The flipping rod 503 is set at a vertical angle before loading, and flips downward to a horizontal angle after loading.

[0033] It should be noted that a hollow shaft motor 5023 is fixedly installed on the outer side of one of the bearing seats 501. The output shaft of the hollow shaft motor 5023 is fixedly connected to the shaft of the tilting shaft 502. A pressure baffle 504 is rotatably installed on the body of the tilting rod 503. Torsion springs 5031 are installed at both ends of the tilting rod 503 and connected to both ends of the pressure baffle 504. A winding motor 5051 is fixedly installed on the outer side of one of the docking frames 505. The output end of the winding motor 5051 is fixedly connected to the winding shaft 5052.

[0034] The flexible film roll 5022 can be stored in the storage seat 5021, or it can be replaced with an air expansion shaft to store the flexible film roll 5022. That is, the inner cylinder of the flexible film roll 5022 is sleeved on the outside of the storage seat 5021 or the air expansion shaft to fix one end of the film roll. The other end of the flexible film roll 5022 can be passed through the through hole in the winding shaft 5052 and wound around the shaft body of the winding shaft 5052, thereby fixing the other end of the roll. Thus, the storage seat 5021 and the winding shaft 5052 can fix the positions of both ends of the flexible film roll 5022 to ensure greater stability when the flexible film roll 5022 is flipped.

[0035] By starting the hollow shaft motor 5023, the flipping shaft 502 can be driven to rotate inside the bearing seat 501. When the bearing seat 501 rotates, the flipping rods 503 on both sides will flip. During the flipping of the flipping rods 503, the end of the flexible film roll 5022 is fixed inside the winding shaft 5052, thereby pulling out the flexible film roll 5022. The flexible film roll 5022 will flip and cover the current material, thereby wrapping the material with the flexible film roll 5022 and isolating it from the outside world, reducing the contact between the material and the outside world during the transfer process, further improving the stability of the material during the transfer. The above structure is automatic, thereby improving the transfer quality and eliminating the need for additional human operation. It should be noted that the flexible film roll 5022 is connected to the storage base 5021 and the take-up shaft 5052 at both ends. During the flipping process, the position of the take-up shaft 5052 will pull one end of the flexible film roll 5022, causing the flexible film roll 5022 to flip to one side. As the flipping continues, the flexible film roll 5022 will pass over the material from above until the take-up shaft 5052 finally flips to the other end, so that the flexible film roll 5022 covers the material. Through the above-mentioned flipping drive, the flexible film roll 5022 will be stretched out and flipped to cover the current material to achieve auxiliary isolation.

[0036] The flexible film roll 5022 can be wound up by activating the winding motor 5051. The old flexible film roll 5022 is wound up for later disposal. This not only allows the flexible film roll 5022 to be straightened to cover the materials, but also ensures that after the materials are removed, the used flexible film roll 5022 is wound back into the winding shaft 5052. This ensures that when new materials are transferred, a new flexible film roll 5022 is used, avoiding contamination of the used material. The material of the flexible film roll 5022 can be antibacterial and heat-insulating film, depending on the specific materials being transported, thus solving the problem of cross-contamination with the external environment during material transportation.

[0037] In the specific setup, the installation platform 1 has an expansion slot 506 inside. An air intake fan 507 is fixedly installed at the upper end of the expansion slot 506. An air filter 508 is installed on the outside of the expansion slot 506. The air filter 508 is connected to the air intake port of the air intake fan 507 through a connecting air pipe 509. A three-way pipe 510 is installed at the air outlet of the air intake fan 507. Connecting hoses 5044 are fixedly installed at both ends of the three-way pipe 510. The pressure baffle 504 has a connecting channel 5041 inside, and the outer end of the connecting channel 5041 is fixedly connected to the connecting hose 5044. An auxiliary impeller 5043 is rotatably installed inside the connecting channel 5041, and an air outlet cavity 5042 is opened on one side of the connecting channel 5041. Air can be introduced into the air outlet cavity 5042 through the connecting channel 5041, and the auxiliary impeller 5043 can make the air more uniform when discharged, improving the exhaust stability.

[0038] By setting a torsion spring 5031 between the pressing baffle 504 and the flipping rod 503, the placement angle of the pressing baffle 504 will be downward by default. The pressing baffle 504 can press the two sides of the flexible film roll 5022, so that the two sides of the flexible film roll 5022 will not open automatically after covering the material, thus ensuring the stability of the flexible film roll 5022 when covering the material. After the air is filtered by the air filter 508, the air intake fan 507 is started to deliver the air to the connecting hose 5044. Under the action of the auxiliary impeller 5043 and the air outlet cavity 5042, the air is blown downward from the gap in a uniform and stable laminar flow state, forming a vertically downward sterile air curtain wall, which provides auxiliary isolation for the underside of the flexible film roll 5022, and can effectively prevent pollutants in the outside air from entering the interior of the material.

[0039] The protective component 5 enables the medical supplies to be isolated and protected, effectively isolating them from external polluted air and preventing them from being contaminated by the external environment during transportation. Furthermore, the addition of flexible film roll 5022 provides insulation, preventing the materials from overheating due to low-temperature diffusion, maintaining a stable low-temperature environment inside the vehicle, ensuring the stability of the materials, and improving the quality of transportation.

[0040] It should be noted that before the roll is flipped, the take-up shaft 5052 is vertically set, that is, the take-up shaft 5052 is above the storage base 5021. The take-up shaft 5052 in the attached drawings of the instruction manual has been flipped to the other end, and in order to show the structural position, one end of the flexible film roll 5022 is not connected to the take-up shaft 5052. In the actual implementation process, one end of the flexible film roll 5022 needs to be fixedly wound around the shaft of the take-up shaft 5052 in advance.

[0041] The working principle of an AGV (Automated Guided Vehicle) for transporting medical supplies: In use, the drive motor 305 first drives the drive wheel 306 to rotate, moving the position of the placement platform 1 to the medical supplies rack, and causing the support tray 402 to move to the underside of the supplies rack, thus completing the loading preparation. Then, by starting the right-angle reduction motor 4075, the transmission gear 4074 is driven to rotate. Under the action of the synchronous gear 4071, the rotating screw 4072 is engaged with the threaded sleeve 4081, thereby supporting the rise of the pallet 402 and lifting the current material rack to load the materials. After loading, the hollow shaft motor 5023 can be started to drive the flipping shaft 502 to rotate inside the bearing seat 501. When the bearing seat 501 rotates, the flipping rods 503 on both sides will flip. During the flipping of the flipping rods 503, the end of the flexible film roll 5022 is fixed inside the winding shaft 5052, thereby extracting the flexible film roll 5022, so that the flexible film roll 5022 will flip and cover the current material, thereby making the flexible film roll 5022 wrap the material and isolate it from the outside world. During the transfer process, the air intake fan 507 is started to deliver air to the connecting hose 5044. Under the action of the auxiliary impeller 5043 and the air outlet cavity 5042, the air is blown out from the gap in a uniform and stable laminar flow state, forming a vertically downward sterile air curtain to perform auxiliary isolation operation on the underside of the flexible film roll 5022. Furthermore, during the transfer process, the temperature above the semiconductor cooling plate 403 is lowered by activating the semiconductor cooling plate 403, which further slows down the temperature rise of the materials and facilitates the automatic transfer of medical supplies.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
