Description

Technical Field

[0001] An vial-turning and dissolving mechanism for an automatic dispensing device belongs to the field of medical dispensing technology. Background Technology

[0002] In the medical field, particularly in the preparation of intravenous medications, automated syringe handling is a crucial step. However, in current medication preparation technologies, the loading, delivery, and positioning of syringes often rely on manual operation. This not only increases the risk of human error but also significantly reduces preparation efficiency. In the medication preparation process, vials are common containers for holding drugs, often powdered medications. Therefore, during preparation, the vials are typically shaken to accelerate the dissolution of the powdered medication.

[0003] In the prior art, there are several ways to shake vials to accelerate dissolution: (1) Rotation. For example, the "via dissolution device" described in the Chinese invention patent with application number 202111573841.8, application date December 21, 2021, entitled "New type of liquid dispensing robot system". (2) Vibration. For example, the "vibration device" described in the Chinese invention patent with application number 201911357778.7, application date December 25, 2019, entitled "An automatic drug dispensing robot", which uses the rotation of a vibrating eccentric motor to form resonance, and the "rapid dissolution device" described in the Chinese utility model patent with application number 201821129680.7, application date July 17, 2018, entitled "An automated injection drug dispensing machine", which uses an eccentric wheel to form vibration. The applicant of this application seeks to design a new technical solution to accelerate the dissolution of drugs in vials. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vial-turning dissolution mechanism for an automatic dispensing device that accelerates the dissolution of the liquid in the vial by setting a flipping drive component to drive the clamping mechanism to flip back and forth in the bracket.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the vial flipping and dissolving mechanism of the automatic dispensing device includes a clamping mechanism for clamping vials, characterized in that: a bracket is provided, the clamping mechanism is horizontally and rotatably installed in the bracket, and a flipping drive assembly for driving the clamping mechanism to reciprocate is installed on the side of the bracket, the flipping drive assembly is connected to the flipping shaft of the clamping mechanism.

[0006] Preferably, the flip drive assembly includes a fixed plate fixed to the bracket, a piston mechanism mounted on the fixed plate, the piston rod of the piston mechanism being connected to the driving member at the top of the fixed plate; one end of the flip shaft passes through the bracket and is mounted with a driven member, the driving member being connected to the driven member.

[0007] Preferably, a sliding mechanism is installed on the upper edge of the fixed plate, the driving component is slidably installed on the upper edge of the fixed plate, and the end of the piston rod is connected to the driving component through a connecting plate.

[0008] Preferably, the driving element is a rack mounted on the upper edge of the fixed plate, and the driven element is a gear coaxially fixed to the end of the flip shaft, with the gear and rack meshing.

[0009] Preferably, the clamping mechanism includes a flipping frame, a flipping shaft passing through the flipping frame, and multiple gripper cylinders for clamping vials arranged side by side inside the flipping frame.

[0010] Preferably, a set of clamping blocks is fixed on the clamping jaws of the clamping cylinder, and grooves are respectively formed on the opposite surfaces of the two clamping blocks.

[0011] Preferably, a trigger plate is installed at the other end of the flip shaft after passing through the bracket, and detection sensors are installed on both sides of the trigger plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the vial-turning and dissolving mechanism of the automatic dispensing device of this application, a turning drive component is set to drive the clamping mechanism to turn back and forth in the bracket, thereby accelerating the dissolution of the drug solution in the vial by turning.

[0013] By installing a trigger plate at the end of the flip shaft and setting a detection sensor that works in conjunction with the trigger plate, the flip angle of the flip shaft can be detected more accurately. Attached Figure Description

[0020] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0021] like Figures 1-2 As shown, an vial-tilting and dissolving mechanism of an automatic dispensing device includes a support 5, the bottom of which is fixed to the surface of the dispensing device's worktable. A clamping mechanism 2 for holding the vials is horizontally mounted on the top of the support 5. The tilting shaft 17 of the clamping mechanism 2 (see...) Figure 5 A gear 3 extends from the side of the bracket 5 and is coaxially fixed thereon. A flip drive assembly 4 is installed at the lower part of the gear 3. The flip drive assembly 4 is connected to the gear 3. By driving the gear 3 to rotate, it further drives the clamping mechanism 2 to flip inside the bracket 5.

[0022] Combination Figure 3 The other end of the flip shaft 17 extends from the side of the bracket 5 and is radially mounted with a trigger plate 6. The trigger plate 6 swings synchronously with the rotation of the flip shaft 17. A detection sensor 1 is mounted on each side of the flip shaft 17. When the trigger plate 6 rotates, it triggers one of the detection sensors 1, causing the flip drive assembly 4 to drive the gear 3 to rotate in the opposite direction. Therefore, through the cooperation of the trigger plate 6 and the detection sensors 1 on both sides, the flip drive assembly 4 drives the clamping mechanism 2 to flip on the upper part of the bracket 5. The detection sensor 1 can be implemented using a mechanical trigger switch (such as a micro switch) or an electronic trigger switch (such as a photoelectric sensor) known in the art.

[0023] like Figure 4 As shown, the tilting drive assembly 4 includes a fixing plate 14, which is fixedly attached to the side of the bracket 5. A fixing frame 12 is mounted on the surface of the fixing plate 14, and a drive cylinder 10 is fixed to the side of the fixing frame 12. The cylinder body of the drive cylinder 10 is fixed to the surface of the fixing frame 12, and its piston rod passes through the fixing frame 12 and connects to one end of a floating joint 11. A connecting plate 7 is mounted on the other end of the floating joint 11. The floating joint 11 is implemented using a commercially available floating universal joint.

[0024] The connecting plate 7 is vertically positioned, with its top extending completely towards and above the fixed plate 14. A slide rail 13 is arranged along the upper edge of the fixed plate 14, and a slider 8 is slidably mounted on the surface of the slide rail 13. A rack 9 is fixed to the surface of the slider 8. The top of the fixed plate 14 is fixedly connected to the end of the rack 9 above the fixed plate 14. The rack 9 meshes with the gear 3. When the drive cylinder 10 operates, it drives the rack 9 to slide back and forth via the connecting plate 7 at the end of its piston rod, further driving the gear 3 to rotate back and forth.

[0025] like Figure 5 As shown, the clamping mechanism 2 includes a tilting frame 18, through which a tilting shaft 17 passes. Multiple gripper cylinders 16 are fixed side-by-side within the tilting frame 18. A gripping block 15 is fixed to the gripper of each gripper cylinder 16. Grooves are formed between two gripping blocks 15 on the same gripper cylinder 16, and the grooves on both sides meet to form a receiving groove for accommodating vials. The gripper cylinders 16 can also be implemented using other components that achieve linear motion, such as a linear motor.

[0026] The specific working process and working principle are as follows: The actuator (such as a robot or manipulator) at the previous workstation delivers the vial to the gripper cylinder 16. The gripper cylinder 16 actuates, and the grippers close, clamping the vial via the clamping block 15. Then, the actuator in the dispensing device injects the vial. The action of injecting the vial into the vial via the actuator using a syringe is common knowledge and practice in the field, as described in Chinese invention patent application number 202410786413.0, filed on June 18, 2024, entitled "An Intelligent Intravenous Drug Dispensing Robot for Tumors and Its Usage Method." The specific implementation of this patent will not be elaborated here.

[0027] After the injection is completed and the syringe is withdrawn from the vial, the drive cylinder 10 operates, causing the piston rod inside to reciprocate. At this time, the piston rod drives the rack 9 to slide back and forth through the connecting plate 7 at its end, which in turn drives the gear 3 to rotate back and forth. The reciprocating rotation of the gear 3 simultaneously drives the flipping shaft 17 and the flipping frame 18 to rotate back and forth inside the support 5, thereby accelerating the dissolution of the drug in the vial.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
