Description
Technical Field
[0001] This invention relates to the field of robotics, specifically to an intelligent medicine delivery robot for use in hospitals. Background Technology
[0002] In the past, the delivery of medicines in hospitals relied heavily on medical staff to manually transport medicines, equipment and other supplies. This not only took up a lot of treatment time, but was also prone to delays or errors due to human factors. Therefore, in order to improve the efficiency of medicine delivery, corresponding medicine delivery robots are usually used.
[0003] For example, a medicine delivery robot with publication number CN112223315A includes an AGV (Automated Guided Vehicle) cart. A rotating mechanism is fixedly installed on the top of the AGV cart, and anti-collision mechanisms are fixedly installed on both sides of the AGV cart. A medicine storage box is fixedly installed at the rotating end of the rotating mechanism. A partition is fixedly installed inside the medicine storage box, and the inside of the medicine storage box is divided into two storage chambers by the partition.
[0004] The existing technologies mentioned above have the following technical problems: Existing drug delivery robots, in order to facilitate the delivery of different types of drugs, have multiple cavities inside the robot, and place corresponding storage boxes in each cavity. However, although setting multiple cavities can meet different needs, it is not necessary for each storage box to be fully loaded with drugs during actual drug delivery. Therefore, setting multiple independent cavities will increase the overall weight of the robot. For electrically driven robots, excessive weight will reduce their own battery life. Moreover, it is not convenient to flexibly switch between cavities with corresponding functions when delivering drugs. At the same time, some robots set up a single cavity to integrate multiple functions. However, if the internal temperature control and shock absorption systems malfunction during subsequent use, the entire robot will be unable to operate and deliver drugs.
[0005] Therefore, we propose an intelligent medicine delivery robot for hospitals to address the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide an intelligent drug delivery robot for hospitals, addressing the aforementioned issues raised in the background section. Existing drug delivery robots on the market typically have multiple internal cavities to accommodate different types of medications, with corresponding storage boxes placed in each cavity. While multiple cavities can meet various needs, it's not always necessary for each storage box to be fully loaded during actual drug delivery. Therefore, multiple independent cavities increase the overall weight of the robot. For electrically driven robots, excessive weight reduces their battery life. Furthermore, multiple independent and fixed cavities make it difficult to flexibly switch between cavities with corresponding functions during drug delivery. Additionally, some robots integrate multiple functions into a single cavity; however, if the internal temperature control and shock absorption systems malfunction, the entire robot becomes unable to operate and deliver medication.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent drug delivery robot for hospitals, comprising a mobile chassis and a connecting frame mounted on the mobile chassis. A receiving frame is fixed to the inner side of the connecting frame, and a rotating protective door is movably connected to the receiving frame. A mobile module is installed inside the receiving frame, and a storage box is connected to the mobile module. A first docking block, a second docking block, and a third docking block are sequentially installed on the side wall of the receiving frame from top to bottom. The side of the receiving frame has slots that are compatible with the first, second, and third docking blocks, and a temperature control unit is installed on the second docking block. After the slots on the side of the receiving frame are respectively docked with the first, second, and third docking blocks, a room-temperature storage area, a low-temperature storage area, and a shock-absorbing storage area are sequentially formed, thereby accommodating drugs with different storage environment requirements.
[0008] Preferably, a ranging unit is provided on the front side of the mobile chassis, and the ranging unit is configured as a lidar.
[0009] By adopting the above technical solution, the distance to obstacles in front can be measured by moving the ranging unit on the chassis during drug delivery.
[0010] Preferably, the mobile module includes a servo motor fixed to the bottom of the accommodating frame, and the output end of the servo motor forms a meshing transmission structure with a transmission screw through a gear set. A moving block is installed on the transmission screw, and the moving block is fixedly connected to the storage box by bolts.
[0011] By adopting the above technical solution, the gear set enables the transmission screw to rotate synchronously with the output shaft of the servo motor, and the rotation of the transmission screw enables the threaded moving block to move.
[0012] Preferably, the moving block and the transmission screw are threadedly connected, and the outer wall of the storage box on the side of the moving block and the inner wall of the accommodating frame fit together, and the cross-section of the moving block is set as a rectangular structure.
[0013] By adopting the above technical solution, the outer wall of the storage box and the inner wall of the accommodating frame are fitted together, thereby preventing the storage box from rotating synchronously with the transmission screw.
[0014] Preferably, the longitudinal sections of the first, second, and third docking blocks are all set to a "U" shape, and the shapes of the first, second, and third docking blocks all match the shape of the groove on the side of the storage box. The edges of the first, second, and third docking blocks are all fixed with sealing rings.
[0015] By adopting the above technical solution, the sealing performance of the edges of the first, second, and third mating blocks can be improved through the sealing rings on the edges of the storage box and the first, second, and third mating blocks.
[0016] Preferably, the shock absorption module includes a guide post and a connecting rod inserted into the guide post, and the guide post and the connecting rod are connected to each other by a spring. An attractive magnet is embedded in the connecting rod, and an adjustment frame is provided on the side of the connecting rod. A pressure rod is fixed to one end of the adjustment frame facing the connecting rod, and an adjustment screw is installed on the adjustment frame. A linkage gear is keyed to the adjustment screw.
[0017] By adopting the above technical solution, the damping effect of the connecting rod moving inside the guide column and the elastic deformation of the spring can effectively reduce shock and buffer the drugs inside the storage box.
[0018] Preferably, the connecting rod forms an elastic telescopic structure through a spring and a guide post, and the upper end of the connecting rod is set as a frustum-shaped structure, and the upper inclined surface of the connecting rod is in contact with the spherical end of the pressure rod.
[0019] By adopting the above technical solution, the connecting rod can be squeezed and pushed by the spherical end of the pressure rod, so that the connecting rod can move on the guide post.
[0020] Preferably, the adjusting screw and the adjusting frame are threadedly connected, and the adjusting frame can slide at the bottom of the receiving frame, and the pressure rods on the adjusting frame correspond one-to-one with the connecting rods.
[0021] By adopting the above technical solution, the rotation of the screw can be adjusted so that the threaded adjustment frame can drive the pressure rod to move synchronously.
[0022] Preferably, a movable base plate is installed inside the storage box, and an electromagnet is embedded in the bottom of the movable base plate. A power rack is fixed to the bottom of the movable base plate. A positioning groove is provided on the side of the storage box, and a locking hole is provided on the side of the positioning groove on the inner side wall of the accommodating frame.
[0023] By adopting the above technical solution, and through the setting of positioning grooves and locking holes, it is convenient to install multiple storage boxes inside the container frame when delivering drugs in multiple batches.
[0024] Preferably, the movable base plate and the storage box are slidably connected, and the power rack at the bottom of the movable base plate can mesh with the linkage gear, and the power rack and the linkage gear correspond one-to-one.
[0025] Compared with the prior art, the beneficial effects of the present invention are: the intelligent drug delivery robot for hospitals, by setting multiple functional cavities inside the robot and setting a movable drug storage box inside the robot, provides the necessary environment for the drug by moving the drug storage box to the corresponding functional cavity, thereby reducing the overall weight of the robot and improving the endurance of the electric drive robot;
[0026] 1. Equipped with a storage box, which facilitates the placement of delivered medications. The rotation of the transmission screw allows the storage box to move vertically. By matching the storage box with the first, second, and third docking blocks, a room temperature storage area, a low temperature storage area, and a shock-absorbing storage area are formed for medications with different storage environment requirements. The edges of the first, second, and third docking blocks are wrapped with sealing rings to improve the sealing performance of the storage box after docking.
[0027] 2. The storage box is equipped with a positioning groove. When the hospital has a high demand for drug delivery, bolts can be used to pass through the positioning groove on the side of the storage box and connect with the locking hole on the receiving frame. This allows storage boxes to be installed on the first docking block, the second docking block, and the third docking block. This enables the transfer of drugs with different storage environment requirements in the same batch through multiple storage boxes.
[0028] 3. A pressure rod is provided. When the transmission screw controls the storage box to move upward, the power rack moves upward and controls the linkage gear to rotate. The rotation of the linkage gear enables the adjusting screw to rotate synchronously. The rotation of the adjusting screw enables the threaded adjustment bracket to drive the pressure rod to move towards the connecting rod. The pressure rod pushes the connecting rod, causing the connecting rod to compress the spring. Thus, when the damping cavity is not needed, the spring cannot be compressed or rebounded, avoiding the shaking of the damping system under unnecessary conditions, improving the service life of the damping system, and preventing fatigue failure caused by frequent compression in non-working conditions.

[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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Example 1: Please refer to Figures 1-9Existing drug delivery robots, designed to accommodate the delivery of different types of medications, typically have multiple internal cavities, each containing a corresponding storage box. While multiple cavities can meet diverse needs, in actual drug delivery, not every storage box needs to be fully filled. Therefore, multiple independent cavities increase the robot's overall weight. For electrically driven robots, excessive weight reduces their battery life. Furthermore, multiple independent and fixed cavities make it difficult to flexibly switch between cavities with specific functions during drug delivery. Additionally, some robots integrate multiple functions into a single cavity, but this integration presents challenges for subsequent use. If the internal temperature control and shock absorption systems malfunction, the entire robot will be unable to operate for drug delivery. To solve this technical problem, this embodiment discloses the following technical content: an intelligent drug delivery robot for hospitals, including a mobile chassis 1 and a connecting frame 2 mounted on the mobile chassis 1. A receiving frame 3 is fixed to the inner side of the connecting frame 2, and a rotating protective door 4 is movably connected to the receiving frame 3. A mobile module is installed inside the receiving frame 3, and a storage box 10 is connected to the mobile module. A first docking block 11, a second docking block 12, and a third docking block 13 are installed sequentially from top to bottom on the side wall of the receiving frame 3. The side of the receiving frame 3 has openings for docking with the first docking block 11, the second docking block 12, and the third docking block 13. The third docking block 13 has a matching slot, and the second docking block 12 is equipped with a temperature control unit 14. After the slots on the side of the accommodating frame 3 are docked with the first docking block 11, the second docking block 12 and the third docking block 13 respectively, a normal temperature storage area, a low temperature storage area and a shock-absorbing storage area are formed in sequence, so as to accommodate drugs with different storage environment requirements. The front side of the mobile chassis 1 is equipped with a ranging unit 5, and the ranging unit 5 is set as a lidar. The mobile module includes a servo motor 6 fixed to the bottom of the accommodating frame 3, and the output end of the servo motor 6 forms a meshing transmission structure with the transmission screw 8 through a gear set 7. A moving block 9 is installed on the transmission screw 8, and the moving block 9 is fixedly connected to the storage box 10 by bolts. The moving block 9 and the transmission screw 8 are threadedly connected, and the outer wall of the storage box 10 on the side of the moving block 9 and the inner wall of the accommodating frame 3 fit together. The cross-section of the moving block 9 is set as a rectangular structure. The longitudinal sections of the first docking block 11, the second docking block 12 and the third docking block 13 are all set as "U" shaped structures. The shapes of the first docking block 11, the second docking block 12 and the third docking block 13 all match the shape of the groove on the side of the storage box 10. The edges of the first docking block 11, the second docking block 12 and the third docking block 13 are all fixed with sealing rings. The side of the storage box 10 is provided with a positioning groove 19, and the side of the positioning groove 19 is provided with a locking hole 20 opened on the inner side wall of the accommodating frame 3.
[0041] When medication delivery is required, the protective door 4 on the receiving frame 3 is opened, and the medication to be delivered is placed inside the storage box 10. The servo motor 6 is then activated. The servo motor 6, through the gear set 7, causes the transmission screw 8 to rotate. The rotation of the transmission screw 8 causes the threaded moving block 9 to move the storage box 10 vertically. After the storage box 10 moves, the side slot mates with the first docking block 11, forming a room temperature storage area. This area can be used to deliver regular medications. When the storage box 10 moves, the side slot mates with the second docking block 12, forming a low-temperature storage area. The temperature control unit 14 on the second docking block 12 can regulate the temperature of the storage space. This low-temperature storage area can be used to deliver special medications such as insulin. When the storage box 10 moves, the side slot mates with the third docking block 13, forming a low-temperature storage area. In the shock-absorbing storage area, when the medicine is being delivered, the shock-absorbing module 15 at the bottom of the third docking block 13 acts as a shock absorber and buffer for the internal medicine. The shock-absorbing storage area can be used to deliver precision medicines or preparations. The sides of the first docking block 11, the second docking block 12, and the third docking block 13 are wrapped with sealing rings, which can improve the sealing at the edge after the storage box 10 docks with them. At the same time, when the demand for medicine delivery in the hospital is large, the side of the storage box 10 is provided with a positioning groove 19. With the setting of the positioning groove 19, after the storage box 10 on the side of the moving block 9 is inserted with one of the docking blocks, the bolts pass through the positioning groove 19 and are screwed into the locking hole 20 on the accommodating frame 3 to connect the two storage boxes 10 with the other two docking blocks respectively. Thus, the interior of the accommodating frame 3 can simultaneously accommodate three storage boxes 10, and different types of medicines can be delivered in parallel at one time.
[0042] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. The following technical content is disclosed in this example: Figures 5-8As shown, the shock absorption module 15 includes a guide post 151 and a connecting rod 152 inserted into the guide post 151. The guide post 151 and the connecting rod 152 are connected to each other by a spring. An attractive magnet 153 is embedded in the connecting rod 152, and an adjustment frame 154 is provided on the side of the connecting rod 152. A pressure rod 155 is fixed to one end of the adjustment frame 154 facing the connecting rod 152, and an adjustment screw 156 is installed on the adjustment frame 154. A linkage gear 157 is keyed to the adjustment screw 156. The connecting rod 152 forms an elastic telescopic structure with the guide post 151 through the spring, and the upper end of the connecting rod 152 is set as a frustum-shaped structure. The upper inclined surface of 2 is in contact with the spherical end of the pressure rod 155. The adjusting screw 156 and the adjusting frame 154 are threadedly connected. The adjusting frame 154 can slide at the bottom of the housing frame 3. The pressure rod 155 on the adjusting frame 154 corresponds one-to-one with the connecting rod 152. The storage box 10 is equipped with a movable base plate 16. An electromagnet 17 is embedded at the bottom of the movable base plate 16. A power rack 18 is fixed at the bottom of the movable base plate 16. The movable base plate 16 and the storage box 10 are slidably connected. The power rack 18 at the bottom of the movable base plate 16 can mesh with the linkage gear 157. The power rack 18 and the linkage gear 157 correspond one-to-one.
[0043] When the slot on the lower side of the storage box 10 aligns with the third docking block 13, the power rack 18 at the lower end of the movable base plate 16 causes the linkage gear 157 to drive the adjusting screw 156 to rotate synchronously. After the adjusting screw 156 rotates, the adjusting frame 154 drives the pressure rod 155 to move away from the connecting rod 152. At this time, the connecting rod 152 is reset under the action of the spring. After the connection rod 152 is reset, the upper end of the connecting rod 152 attracts the magnetic block 153 and the electromagnet 17 at the bottom of the movable base plate 16. After the electromagnet 17 is energized, it attracts the magnetic block 153. Subsequently, when vibration occurs during delivery, the movable base plate 16 moves on the storage box 10, which allows the connecting rod 152 to move synchronously on the guide post 151. The damping effect and the elastic deformation of the spring can thus play a shock absorption and buffering role. When the medicine that needs shock absorption is not needed is delivered, the electromagnet 17 is turned off, the attraction of the magnetic block 153 is released, and after the storage box 10 moves upward, the drive rack 18 can drive the linkage gear 157 and the adjusting screw 156 to rotate in the opposite direction. After the adjusting screw 156 rotates in the opposite direction, the threaded adjustment bracket 154 and the pressure rod 155 can move towards the connecting rod 152. After the pressure rod 155 is reset, it can press the connecting rod 152 downward. After the connecting rod 152 is compressed, the spring is compressed. After that, when shock absorption is not needed, the spring cannot be compressed or rebounded, avoiding the shaking of the shock absorption system under unnecessary conditions, improving the service life of the shock absorption system, and preventing fatigue failure caused by frequent compression in non-working conditions.
[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
