DETAILED DESCRIPTION

[0012] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0013] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0014] As shown in Figures 1-10 The present application discloses a medicine taking mechanism, a medicine dispensing device and an automatic medicine dispensing equipment. The disclosed medicine taking mechanism is applied to the medicine dispensing device, wherein the medicine dispensing device comprises a medicine storage groove 300 and a medicine taking mechanism 400, the medicine taking mechanism 400 is arranged at the discharging end of the medicine storage groove 300, and the medicine taking mechanism is used to cooperate with the medicine taking mechanism 400 to realize taking the medicine bottles stored in the medicine storage groove 300.

[0015] Specifically, as shown in Figures 1-4 The medicine taking mechanism 100 includes a bracket 110, a receiving groove 120, a door body 130, a driving mechanism 140, and an execution assembly 150. The bracket 110 is a basic component of the medicine taking mechanism 100 and provides a mounting basis for the receiving groove 120, the door body 130, the driving mechanism 140, and the execution assembly 150, i.e., the receiving groove 120, the door body 130, the driving mechanism 140, and the execution assembly 150 are all arranged on the bracket 110.

[0016] As shown in Figure 1 The receiving groove 120 is arranged obliquely relative to the horizontal plane. When the medicine taking mechanism is connected to the medicine storage groove 300, the upper end of the receiving groove 120 corresponds to the discharging end of the medicine storage groove 300, and the lower end of the receiving groove 120 is used to unload and transfer the medicine bottles to the basket. The door body 130 is movably arranged at the lower end of the receiving groove 120 based on the bracket 110, and the driving mechanism 140 is connected to the door body 130 to drive the door body 130 to move, so as to realize the shielding or avoiding of the slot at the lower end of the receiving groove 120. It can be understood that, in the case that the door body 130 shields the slot at the lower end of the receiving groove 120, the receiving groove 120 can temporarily store the medicine bottles until the lower end of the receiving groove 120 corresponds to the basket, and then the driving mechanism 140 can drive the door body 130 to move to unload and transfer the medicine bottles to the basket.

[0017] In the embodiment of the present application, the execution assembly 150 includes a driving member 151 and an execution member 152 connected to the driving member 151. The execution member 152 is configured to move under the driving of the driving member 151, so as to trigger the discharging action of the discharging mechanism 400. Exemplarily, the driving member 151 can be a linear motor or an electric push rod fixedly arranged on the bracket 110, and the execution member 152 is slidingly fitted on the bracket 110. The driving member 151 drives the execution member 152 to linearly move, so as to trigger the discharging action of the execution assembly 150.

[0018] Based on the above technical solution, please refer to Figure 3 and Figure 4 When the medicine taking mechanism is connected to the discharging end of the medicine storage groove 300, the execution assembly 150 drives the execution member 152 to move through the driving of the driving member 151, and forms linkage with the discharging mechanism 400 of the discharging end of the medicine storage groove 300. The discharging action is only performed when the execution member 152 is triggered. At this time, the medicine bottles in the medicine storage groove 300 can roll and slide into the receiving groove 120 under the action of gravity. The door body 130 shields the slot of the receiving groove 120, so as to temporarily store the medicine bottles in the receiving groove 120. The medicine bottles are unloaded and transferred to the basket when the lower end of the receiving groove 120 is aligned with the basket. This kind of automatic medicine taking mode effectively avoids the medical risk caused by the wrong taking of medicines, and effectively avoids the scattering and pollution of medicines.

[0019] In the embodiment of the present application, please continue to refer toFigure 1 And Figure 2 The support 110 is provided with an identification device 170, and the medicine outlet mechanism 400 is provided with an identification chip 450. The identification chip 450 of each medicine outlet mechanism 400 stores specific information of the medicine in the current medicine storage slot 300. Exemplarily, the specific information can be batch information, expiration date information, medicine type information, dose information, etc. of the medicine. Exemplarily, the identification device 170 can be an RFID code reader, and the identification chip 450 can be an RFID chip. When the medicine taking mechanism is docked with the medicine outlet mechanism 400 to prepare for medicine taking, the system needs to verify that the information of the identification chip 450 is consistent with the prescription information or the inventory data through the identification device 170 first, and then control the execution assembly 150 to act, so as to effectively prevent expired medicines, wrong medicines or unauthorized medicines from being taken out, and reduce the risk of medical accidents.

[0020] In some embodiments of the present application, the door body 130 is movably arranged on the support 110 in a liftable manner. Exemplarily, the driving mechanism 140 includes a first motor 141 and a first linear movement assembly 142. The door body 130 is connected with the first linear movement assembly 142. The first motor 141 is configured to drive the first linear movement assembly 142 to drive the door body 130 to ascend or descend relative to the support 110. When the door body 130 ascends, it avoids the notch at the lower end of the receiving slot 120. When the door body 130 descends, it blocks the notch of the receiving slot 120. Exemplarily, the first linear movement assembly 142 can be a synchronous wheel assembly. The synchronous wheel assembly includes a driving synchronous wheel, a driven synchronous wheel, and a synchronous belt sleeved on the driving synchronous wheel and the driven synchronous wheel. The driving synchronous wheel and the driven synchronous wheel are arranged in a longitudinal direction. The connecting piece can be clamped and fixed to the synchronous belt through a threaded fastener, and the connecting piece can also be connected and fixed with the door body 130 through a threaded fastener. When the first motor 141 drives the driving synchronous wheel to rotate, the synchronous belt can drive the door body 130 to ascend or descend through the connecting piece. Of course, in some other embodiments of the present application, the first linear movement assembly 142 can also be a ball screw mechanism, a gear and rack mechanism, etc., which are not limited in the present application.

[0021] In further technical solutions, please continue to see Figure 1 And Figure 2The counting sensor 160 is arranged at the notch above the receiving groove 120. For example, the counting sensor 160 can be a photoelectric sensor or an infrared counter. When a single medicine bottle falls into the receiving groove 120, the counting sensor 160 can monitor the falling of the single medicine bottle and count the same. At this time, the driving member 151 can be controlled to drive the executing member 152 to move away from the contact with the medicine outlet mechanism 400. If multiple medicine bottles need to be taken out, the driving member 151 can be controlled to drive the executing member 152 to move to contact with the executing member 152 again. That is to say, the medicine taking action of the medicine taking mechanism 100 can be intermittent multiple taking actions to avoid the situation that multiple medicine bottles are taken out at one time. Until the number of the medicine bottles in the receiving groove 120 reaches the target number, the number of the medicine taken each time is strictly consistent with the prescription or the system instruction.

[0022] In a further technical solution, the bracket 110 is further provided with a detection sensor 180, which is arranged towards the outlet end of the medicine storage groove 300. The detection sensor 180 is used to detect whether there is a medicine bottle at the outlet end of the medicine storage groove 300. When the detection sensor 180 detects that the medicine storage groove 300 is in an empty state, the system can query other storage positions, so that the medicine taking mechanism can quickly respond and move to the next target storage position. Meanwhile, an alarm can be triggered to prompt the staff to replenish the medicine, so as to prevent subsequent process errors and improve the reliability of the equipment.

[0023] As shown in Figures 3-10 , the application further discloses a medicine dispensing device. The disclosed medicine dispensing device comprises a rack 200, a medicine storage groove 300, a medicine outlet mechanism 400, a horizontal and vertical lifting mechanism 500, and the aforementioned medicine taking mechanism. The plurality of medicine storage grooves 300 are arranged in the rack 200. The bracket 110 of the medicine taking mechanism is connected with the horizontal and vertical lifting mechanism 500. The horizontal and vertical lifting mechanism 500 can drive the medicine taking mechanism to move horizontally and / or vertically, so that the medicine taking mechanism can correspond to different positions of the medicine storage groove 300 to perform the medicine taking action.

[0024] In the embodiment of the application, please refer to Figure 3 、 Figure 4 and Figure 5The horizontal lifting mechanism 500 includes a longitudinal beam 510, a crossbeam 520, a second linear movement component 530, a second motor 540, a third linear movement component 550, and a third motor 560. Two longitudinal beams 510 are arranged parallel to each other on the frame 200. Each longitudinal beam 510 is provided with a second linear movement component 530. The two ends of the crossbeam 520 are connected to the two second linear movement components 530. The second motor 540 is configured to drive the second linear movement component 530 to move the crossbeam 520 up or down. The third linear movement component 550 is located on the crossbeam 520. The bracket 110 is connected to the third linear movement component 550. The third motor 560 is configured to drive the third linear movement component 550 to move the bracket 110 laterally.

[0025] In this embodiment, the second linear movement component 530 and the third linear movement component 550 can employ a belt-slider mechanism, a ball screw mechanism, a synchronous pulley assembly, etc. The second linear movement component 530 and the third linear movement component 550 can choose the same linear movement form or different linear movement forms; this application does not impose specific limitations in this regard. It should be noted that, to ensure the consistency of the lifting and lowering movements at both ends of the crossbeam 520, a second motor 540 can drive two second linear movement components 530. For example, the power output end of the second motor 540 is connected to a synchronous dual-output shaft reducer, and the two output ends of the synchronous dual-output shaft reducer are connected to the two second linear movement components 530.

[0026] Based on the above technical solution, the second motor 540 can drive the medicine dispensing mechanism to move longitudinally, and the third motor 560 can drive the medicine dispensing mechanism to move laterally. This enables one medicine dispensing mechanism to dispense medicine from multiple medicine storage tanks 300 at different locations, eliminating the need to configure a separate medicine dispensing mechanism for each medicine storage tank 300, significantly reducing the number of devices and space occupation, and adapting to compact pharmacy layouts.

[0027] In the embodiments of this application, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The dispensing mechanism 400 is located at the discharge end of the medicine storage tank 300. The dispensing mechanism includes a tray 410, a shielding component 420, a triggering component 430, and an elastic reset mechanism 440. The tray 410 is the basic component of the dispensing mechanism of the medicine storage tank and can provide an installation base for the shielding component 420, the triggering component 430, and the elastic reset mechanism 440. That is, the shielding component 420, the triggering component 430, and the elastic reset mechanism 440 are located on the tray 410.

[0028] The tray 410 can be part of the bottom wall of the medicine storage tank. The tray 410 is used to support medicine bottles. For example, the medicine bottles can be ampoules or vials. Multiple medicine bottles are arranged and supported on the tray 410 to form a medicine bottle array. In this embodiment, for ease of subsequent description, along the discharge direction of the medicine bottles, the first medicine bottle at the foremost point is defined as the first medicine bottle 600, and the second medicine bottle immediately behind the first medicine bottle 600 is defined as the second medicine bottle 700.

[0029] In this embodiment of the application, the shielding component 420 is rotatably disposed relative to the tray 410. For example, the shielding component 420 has a rotating shaft 426. When the medicine dispensing mechanism of the medicine storage tank is installed in the medicine storage tank, the rotating shaft 426 can rotate and cooperate with the side wall of the medicine storage tank, thereby rotating relative to the tray 410. Of course, it can also be understood that the shielding component 420 swings relative to the tray 410. The shielding component 420, which is rotatably disposed relative to the tray 410, has a first state and a second state. In the first state, the shielding component 420 shields the first medicine bottle 600. At this time, all medicine bottles arranged after the first medicine bottle 600 are sequentially limited and blocked. When the shielding component 420 rotates relative to the tray 410 to the second state, the shielding component 420 avoids the first medicine bottle 600, allowing the first medicine bottle 600 to be output from the front end of the tray 410. For example, the tray 410 is tilted relative to the horizontal plane, and the first medicine bottle 600 can fall from the front end of the tray 410 under the action of gravity. At the same time, the shielding component 420 in the second state also shields the second medicine bottle 700 to prevent it from falling with the first medicine bottle 600, thereby preventing continuous dispensing of medicine.

[0030] In this embodiment, both the trigger 430 and the elastic reset mechanism 440 are connected to the blocking assembly 420, and are distributed on opposite sides of the blocking assembly 420. The trigger 430 can be a rod-shaped member. When the drug dispensing mechanism is in contact with the drug dispensing mechanism 400 of a drug storage tank, the driving member 151 drives the executing member 152 to abut against the trigger 430 and move the trigger 430. The trigger 430 pushes the blocking assembly 420 to rotate, thereby switching the blocking assembly 420 from a first state to a second state. During this process, the elastic reset mechanism 440 stores elastic potential energy. When the executing member 150 removes the abutting force applied to the trigger 430, the elastic reset mechanism 440 releases the elastic potential energy, which can drive the blocking assembly 420 to rotate again, switching it from the second state back to the first state.

[0031] Through the coordinated operation of the blocking component 420, the trigger 430, and the elastic reset mechanism 440, the blocking component 420 can switch between the first state and the second state. In the second state, only the first medicine bottle 600 is released, and the second medicine bottle 700 cannot move forward due to continuous blocking, thus completely avoiding the risk of multiple bottles sliding out or getting stuck. This meets the strict single-dose control requirements for drug dispensing in medical scenarios, reducing the intensity of manual operation while ensuring the accuracy and efficiency of drug dispensing.

[0032] In the embodiments of this application, please refer to Figure 8 , Figure 9 and Figure 10 The shielding component 420 includes a substrate 421, a first swing arm 422, a second swing arm 423, a first shielding member 424, and a second shielding member 425. The substrate 421 is movably disposed on the support plate 410, and the two ends of the substrate 421 are distributed on opposite sides of the support plate 410. The first swing arm 422 and the second swing arm 423 are respectively connected to the upper and lower ends of the substrate 421. The first swing arm 422 is located above the support plate 410, and the second swing arm 423 is located below the support plate 410. The first swing arm 422, the substrate 421, and the second swing arm 423 are connected to form a U-shaped structure.

[0033] In this embodiment, the rotation shaft 426 of the blocking component 420 is biased in the moving direction of the trigger 430, so that the blocking component 420 can rotate relative to the support plate 410. Exemplarily, the rotation shaft 426 of the blocking component 420 is located at the lower part of the blocking component 420, for example, at the junction of the second swing arm 423 or the base plate 421 and the second swing arm 423. The first blocking member 424 is connected to the first swing arm 422, and the second blocking member 425 is connected to the second swing arm 423.

[0034] In the first state, the first blocking member 424 is located outside the first medicine bottle 600 to block the first medicine bottle 600. In the second state, the first blocking member 424 is raised to avoid the first medicine bottle 600, and the second blocking member 425 is raised and inserted between the first medicine bottle 600 and the second medicine bottle 700, thereby blocking the second medicine bottle 700. That is to say, the U-shaped structure, the first blocking member 424 and the second blocking member 425 form a seesaw-like structure, allowing the first blocking member 424 and the second blocking member 425 to selectively intervene in the medicine bottle's dispensing path. When the first blocking member 424 intervenes, it blocks the first medicine bottle 600, and when the second blocking member 425 intervenes, it blocks the second medicine bottle 700.

[0035] Both the trigger 430 and the elastic reset mechanism 440 are connected to the base plate 421. When the trigger 430 is moved by the abutment of the actuator 152, it can drive the U-shaped structure to rotate around its rotation axis 426, thereby switching the blocking component 420 from the first state to the second state. It can be understood that when the actuator 150 is disengaged from the trigger 430, the elastic reset mechanism 440 drives the blocking component 420 to rotate and switch from the second state to the first state. The second medicine bottle 700 loses its constraint and moves on the tray 410 to the position of the first medicine bottle 600 and is blocked by the first blocking component 424. At this time, the second medicine bottle 700 changes into the first medicine bottle 600.

[0036] In this embodiment, the rotation shaft 426 of the shielding assembly 420 is located below the tray 410, such that the first shielding member 424 intervenes from above to shield the first medicine bottle 600, while the second shielding member 425 intervenes from below to shield the second medicine bottle 700. In other embodiments of this application, the rotation shaft 426 may also be located above the tray 410, for example, at the intersection of the base plate 421 and the first swing arm 422. When the rotation shaft 426 of the shielding assembly 420 is located above the tray 410, the first shielding member 424 can intervene from below to shield the first medicine bottle 600, and the second shielding member 425 can intervene from above to shield the second medicine bottle 700. This application does not impose specific limitations on this.

[0037] In this embodiment, the pallet 410 is provided with slots 411 penetrating the pallet 410. Multiple slots 411 are distributed along the width direction of the pallet 410, which is perpendicular to the conveying direction of the medicine bottle. A portion of the second blocking member 425 can pass through the slots 411 and extend between the first medicine bottle 600 and the second medicine bottle 700. With this configuration, the multiple slots 411 distributed along the width direction of the pallet 410 provide continuous blocking for the body of the medicine bottle by the second blocking member 425, preventing the medicine bottle from tilting due to partial blocking. Furthermore, the pallet 410 has a solid portion between two adjacent slots 411. When the second blocking member 425 retracts and removes its blocking effect on the medicine bottle, the medicine bottle is always supported by this solid portion as it passes through the slot 411, thus preventing the medicine bottle from partially sinking into the slot 411 and becoming stuck, thereby ensuring smooth dispensing of the medicine bottle.

[0038] As described above, the blocking component 420 rotates when driven by the trigger 430 or the elastic reset mechanism 440. Therefore, the connection between the trigger 430 and the blocking component 420 slides relative to each other, allowing the blocking component 420 to rotate about its rotation axis 426. Thus, in some embodiments of this application, the trigger 430 has a pin 431, and a guide groove 4211 is provided on the substrate 421. Exemplarily, the guide groove 4211 is located in the middle of the substrate 421, and both ends of the guide groove 4211 extend towards both ends of the substrate 421. The pin 431 is slidably engaged within the guide groove 4211. That is, the sliding engagement between the guide groove 4211 and the pin 431 essentially converts the linear motion of the trigger 430 into the rotational motion of the blocking component 420 about the rotation axis 426. Please refer to [link to relevant documentation]. Figure 10 When the trigger 430 moves to the left under the action of an external force, the blocking assembly 420 rotates counterclockwise around the rotation axis 426, and at this time the pin 431 moves upward relative to the guide groove 4211; when the external force is removed, the elastic reset mechanism 440 can drive the trigger 430 to move to the right, the blocking assembly 420 rotates clockwise around the rotation axis 426, and the pin 431 moves downward relative to the guide groove 4211.

[0039] In this embodiment, the elastic reset mechanism 440 includes a spring seat 441, a spring 442, and a top pin 443. The spring seat 441 can be disposed on the support plate 410 and has a receiving space. The spring 442 is disposed in the receiving space. The top pin 443 abuts against the spring 442 and the base plate 421, and a portion of the top pin 443 is located inside the spring 442. During the process of the trigger member 430 driving the blocking assembly 420 to switch from the first state to the second state, the spring 442 is compressed and stores elastic potential energy.

[0040] In a further technical solution, the substrate 421 has a flange 4212 on the side facing the top pin 443. The outer peripheral surface of the flange 4212 is an arc-shaped surface. The top pin 443 abuts against the outer peripheral surface of the flange 4212. The arc-shaped outer peripheral surface of the flange 4212 and the top pin 443 form a line-to-surface contact, which reduces the friction between the top pin 443 and the substrate 421, thereby improving the smoothness of the rotation of the shielding assembly 420.
