Description

Technical Field

[0001] This application relates to the technical field of reagent preparation, and in particular to a cylinder-based bottle liquid shaking mechanism. Background Technology

[0002] During reagent preparation, staff inject the ampoule solution into the vial using a syringe, mix them, and then shake to ensure that the solution and powder are fully dissolved. Finally, staff manually use a syringe to draw the mixed solution from the vial and transfer it to a liquid bag for sealing and storage.

[0003] Although the process of preparing the medicine solution can be completed manually, manually shaking the solution is inefficient.

[0004] In response, existing technologies employ various alternatives, such as traditional vortex oscillators or orbital oscillators. These devices are typically benchtop and can only perform single-dimensional (horizontal or vortex) oscillations. For highly viscous liquids or those requiring special mixing trajectories, the shaking effect is not ideal.

[0005] Other systems are large-scale, fully automated liquid preparation robots. These systems are highly integrated and can automate the entire process from liquid extraction, mixing, and shaking to dispensing. However, they have significant drawbacks: their structure is extremely complex, they occupy a large area, and they usually require dedicated isolation enclosures or large workbenches. They are also very expensive, costing hundreds of thousands or even millions of yuan, limiting their use to large hospital pharmacies or large pharmaceutical companies; smaller and medium-sized components cannot afford them. Therefore, further improvements are needed. Summary of the Invention

[0006] To address the above problems, this application provides a cylinder-based liquid mixing mechanism.

[0007] This application provides a cylinder-based bottle liquid shaking mechanism, which adopts the following technical solution: A cylinder-based bottle-mixing mechanism includes a turntable, a first drive assembly for intermittently rotating the turntable around its own axis, a support assembly mounted on the turntable, a second drive assembly mounted on the support assembly, and a clamping assembly mounted on the second drive assembly for clamping ampoules. The support assembly, from bottom to top, includes a cylinder top plate, a guide rod connected to the cylinder top plate, a fixed plate through which the guide rod passes, and a support plate mounted above the fixed plate. The upper end of the guide rod is connected to the support plate. The second drive assembly includes a vertical cylinder mounted on the fixed plate, which drives the clamping assembly to reciprocate vertically. The clamping assembly includes grippers for clamping ampoules and a drive component for moving the grippers. Two grippers are provided and symmetrically arranged along the ampoules.

[0008] By adopting the above technical solution, firstly, the driving component drives the gripper to hold the ampoule that needs to be shaken. After gripping, the vertical cylinder is activated, with its piston rod abutting against the cylinder top plate, allowing the vertical cylinder to effectively transmit power to the supporting component, driving the gripping component to perform vertical reciprocating motion, thereby realizing the vertical shaking operation of the ampoule. During the shaking process in the height direction, the first driving component is activated to drive the turntable to perform intermittent rotation around its own axis. Both work together on the ampoule to achieve efficient shaking. During the shaking process, the guide rod is set to limit the height direction. Compared with the existing technology, it can perform shaking in both the horizontal and vertical directions, resulting in more uniform shaking overall. Moreover, compared with the large shaking equipment in the existing technology, the cost and space occupied are reduced.

[0009] Preferably, the drive assembly further includes a return spring coaxially sleeved outside the guide rod. Two return springs are provided, one of which is disposed between the cylinder top plate and the fixed plate, and the other is disposed between the fixed plate and the support plate.

[0010] By adopting the above technical solution, during the operation of the bottle-shaking assembly, when the cylinder top plate drives the guide rod to move under the action of the vertical cylinder, the return springs located between the cylinder top plate and the fixed plate, and between the fixed plate and the support plate, can play a buffering and restoring role during the movement of the guide rod. When the guide rod moves upward or downward, the return springs are compressed or stretched, buffering the impact force during the movement and preventing rigid collisions from damaging the assembly. When the force of the vertical cylinder disappears, the return springs can use their own elastic restoring force to return the guide rod, cylinder top plate, fixed plate, and support plate to their initial positions, ensuring that the bottle-shaking assembly can stably and reliably perform multiple intermittent movements, improving the service life and operational stability of the assembly, and also improving the collision effect between solids and liquids, thereby improving the shaking effect.

[0011] Preferably, a limit rod is provided on the upper surface of the fixing plate, and the piston rod of the vertical cylinder abuts against the top plate of the cylinder.

[0012] By adopting the above technical solution, the limiting rod set on the upper surface of the fixed plate can limit the movement of the load-bearing component, prevent its movement from exceeding the reasonable range, and ensure the stability and safety of the component operation.

[0013] Preferably, a platform for placing the ampoule is provided above the support plate, and the platform is tilted at a certain predetermined angle relative to the horizontal plane.

[0014] By adopting the above technical solution, placing the ampoule on a platform at a predetermined angle relative to the horizontal plane increases the mixing trajectory and dimension of the medicine solution inside the ampoule, resulting in more thorough mixing and improved shaking effect. It also facilitates the direct insertion of a needle into the ampoule after shaking to aspirate the mixed medicine.

[0015] Preferably, the driving component is a pneumatic finger cylinder, which includes a cylinder body disposed on the support plate, a guide rail disposed on the cylinder body, and a slider slidably connected to the guide rail. The slider is rotatably connected to a rotating rod, and the gripper is connected to the rotating rod. The support plate is provided with a control component, which is used to drive the gripper to swing as the vertical cylinder rises and falls.

[0016] By adopting the above technical solution, the driving component uses a pneumatic finger cylinder, the cylinder body of which is mounted on a support plate. A guide rail is provided on the cylinder body, and a slider slides on the guide rail. The slider rotates and connects to a rotating rod, and the gripper is connected to the rotating rod. Furthermore, a control component is provided on the support plate, enabling the gripper to swing as the vertical cylinder rises and falls. This structural design allows for flexible and stable clamping and swinging of the ampoule during the liquid mixing process. Compared to traditional fixed clamping methods, this increases the amplitude and frequency of liquid shaking within the ampoule, effectively improving the mixing effect and shaking efficiency.

[0017] Preferably, the gripper includes a vertical part fixedly connected to the rotating rod, a horizontal part perpendicular to the vertical part, and a clamping part disposed on the horizontal part. The control component includes a control rope connected to the horizontal part / clamping part and a torsion spring coaxially sleeved on the rotating rod. The other end of the control rope is connected to the piston rod / fixed plate of the vertical cylinder. The torsion spring is used to drive the gripper to reset. The support plate is provided with a mounting bracket for the placement platform to rotate and connect to.

[0018] By adopting the above technical solution, the vertical part of the gripper is fixedly connected to the rotating rod, the horizontal part is perpendicular to the vertical part, and the clamping part is located on the horizontal part. This structural design allows the gripper to stably cooperate with the rotating rod to achieve corresponding actions. The control rope in the control component connects the horizontal part or the clamping part to the piston rod or fixed plate of the vertical cylinder. When the vertical cylinder is activated, the control rope can drive the gripper to swing, realizing the clamping and releasing operation of the ampoule. The torsion spring coaxially sleeved on the rotating rod can drive the gripper to return to its original position after the gripper moves, ensuring that the gripper can work repeatedly and stably. The mounting bracket on the support plate is rotatably connected to the placement platform, so that when the ampoule on the placement platform is operated by the gripper, the placement platform can rotate accordingly, thereby improving the flexibility and stability of the operation of the ampoule, and thus improving the mixing effect of the liquid in the bottle.

[0019] Preferably, the control rope can be an elastic rope.

[0020] By adopting the above technical solution and setting the control rope as an elastic rope, the elasticity can be used to provide buffer when driving the gripper to swing, reducing excessive impact on the gripper and related components, extending the service life of the components, and also better adapting to different working states and working conditions.

[0021] Preferably, the control component includes a control spring, one end of which is connected to the fixed plate, and the other end of which is connected to the gripper.

[0022] By adopting the above technical solution, the control component uses a control spring, with one end of the control spring connected to a fixed plate and the other end connected to a gripper. When the vertical cylinder drives the clamping assembly to reciprocate in the vertical direction, the control spring can extend and retract with the movement of the gripper. Utilizing the elastic properties of the spring itself, the swing of the gripper can be controlled more stably and flexibly, allowing the gripper to better adapt to the positional changes of the ampoule and accurately clamp and release it, ensuring effective clamping of the ampoule, and thus improving the stability and reliability of the liquid mixing.

[0023] Preferably, the clamping part has an elastic layer near the surface of the medicine bottle, the elastic layer has a cavity, and the clamping part has a through groove communicating with the cavity on the surface near the elastic layer. The gripper is slidably connected to a piston in the through groove. The through groove and the cavity are filled with a medium. The control rope passes through the horizontal part / clamping part to connect with the piston. The length of the through groove is less than the arc length of the gripper swing. When the control rope drives the gripper to swing, it drives the piston to move towards the elastic layer to expand the elastic layer and squeeze the ampoule.

[0024] By employing the above technical solution, when the control rope drives the gripper to swing, the tension of the control rope first acts on the piston to allow it to slide within the groove. As the piston moves towards the elastic layer, its movement compresses the medium within the cavity, causing a sudden increase in pressure. This high pressure forces the elastic gripping part wall to expand and deform outwards (towards the medicine bottle). Thus, before the gripper begins to swing, the gripping force is significantly enhanced, and the medicine bottle is held more tightly and snugly. When the piston reaches its stroke limit (mechanical stop), the tension on the control rope continues to increase. This tension overcomes the torque of the torsion spring, pulling the rotating rod and forcing the entire gripper to swing around the hinge point. The gripper adaptively swings based on the increased gripping force, always maintaining optimal contact with the bottle body, exhibiting extremely high dynamic stability. This enhances the gripping effect on the ampoule, reduces bottle shaking or detachment during swinging, and improves the stability of the shaking process.

[0025] Preferably, the elastic layer has anti-slip texture on the surface near the ampoule.

[0026] By adopting the above technical solution, and by setting anti-slip textures on the surface of the elastic layer near the ampoule, the friction between the elastic layer and the ampoule can be increased, reducing the slippage of the ampoule during shaking and improving the stability and effect of shaking.

[0027] In summary, this application has the following beneficial effects: 1. The first drive component drives the turntable to rotate intermittently, and the second drive component drives the clamping component to reciprocate vertically, which can realize multi-dimensional movement of the ampoule and solve the problem that the single-dimensional oscillation of the traditional shaker is not good for shaking liquids with high viscosity or special mixing trajectories, thus improving the shaking effect. 2. Compared with large-scale fully automated liquid dispensing robot systems, this component has a simpler structure, occupies less space, reduces costs, and solves the problems of complex structure, high cost, and difficulty for small and medium-sized institutions to afford large-scale fully automated liquid dispensing robot systems.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail below.

[0031] This application discloses a cylinder-based liquid mixing mechanism.

[0032] Example 1: A cylinder-based bottle liquid shaking mechanism, as described above. Figure 1 , Figure 2 It includes a frame 1, a turntable 2 rotatably connected to the frame 1, a first drive assembly 3 for driving the turntable 2 to rotate intermittently around its own axis, a support assembly 4 disposed on the turntable 2, a second drive assembly 5 disposed on the support assembly 4, and a clamping assembly 6 disposed on the second drive assembly 5 for clamping the ampoule 11.

[0033] The first drive assembly 3 is mounted on the frame 1. The first drive assembly 3 can be a drive motor mounted on the frame 1 and a reducer connected to the drive motor. The drive motor can be a servo motor or a stepper motor, electrically connected to a controller to control the rotation angle and start / stop of the drive motor to achieve "intermittent rotation". Alternatively, it may include two gears, one located on the output shaft of the drive motor and the other connected to the turntable 2. The two gears mesh, and when the drive motor is started, it drives the turntable 2 to rotate. The first drive assembly 3 can also be a combination of a hydraulic motor and a speed control valve. The hydraulic motor outputs power to drive the turntable 2 to rotate, and the speed control valve adjusts the speed of the hydraulic motor, thereby achieving intermittent rotation of the turntable 2. The specific configuration depends on the requirements.

[0034] Reference Figure 2 , Figure 3 The load-bearing component 4, from bottom to top, includes a cylinder top plate 41, a guide rod 42 connected to the cylinder top plate 41, a fixing plate 43 through which the guide rod 42 passes, and a support plate 44 disposed above the fixing plate 43. The cylinder top plate 41 is disposed below the turntable 2, and the fixing plate 43 is fixedly connected to the upper surface of the turntable 2. In this embodiment, several guide rods 42 are provided, which can be arranged in a matrix along the fixing plate 43 or spaced apart around the axis of the fixing plate 43, depending on the requirements. The upper end of the guide rod 42 is connected to the support plate 44. The guide rod 42 plays a guiding and supporting role, ensuring the stability of the load-bearing component 4. The guide rod 42 is usually made of high-strength metal materials, such as stainless steel, to ensure that it has sufficient strength and rigidity. The guide rod 42 can also be made of lightweight materials such as aluminum alloy to reduce the overall weight. The fixing plate 43 and the support plate 44 are generally made of steel plates or plastic plates, and the appropriate materials are selected according to actual needs.

[0035] The second driving assembly 5 includes a vertical cylinder 51 fixedly connected to the fixed plate 43 and a return spring 52 coaxially sleeved on the guide rod 42. The piston rod of the vertical cylinder 51 passes through the fixed plate 43 and abuts against the cylinder top plate 41. The vertical cylinder 51 is used to drive the clamping assembly 6 to perform vertical reciprocating motion. When the vertical cylinder 51 is working, the piston rod pushes the cylinder top plate 41, and with the connection of the guide rod 42, it drives the entire bearing assembly 4 and clamping assembly 6 to perform vertical movement. In this embodiment, two return springs 52 are provided. One is provided between the cylinder top plate 41 and the fixed plate 43, and the other is provided between the fixed plate 43 and the support plate 44. Mounting blocks 521 are fixedly connected to the surfaces of the cylinder bottom plate, the fixed plate 43, and the support plate 44 near the return spring 52 for fixed connection with the return spring 52. In this embodiment, the reset spring 52 is generally a helical spring, which has good elasticity and reset performance. The material of the reset spring 52 is usually spring steel to ensure its strength and elasticity.

[0036] Furthermore, a limit rod 45 is provided on the upper surface of the fixing plate 43, which can limit the movement of the bearing component 4, prevent its movement from exceeding the reasonable range, and ensure the stability and safety of the component operation.

[0037] The clamping assembly 6 includes grippers 61 for clamping the ampoule 11 and a drive member 62 for moving the grippers 61. Two grippers 61 are provided and symmetrically arranged along the ampoule 11. The grippers 61 are typically made of elastic materials such as plastic or rubber to avoid damaging the ampoule 11. The grippers 61 may also be made of metal with a layer of soft material on the surface. Specifically, the grippers 61 include a clamping portion 611 for clamping the ampoule 11, a horizontal portion 612 connected to the clamping portion 611, and a vertical portion 613 perpendicular to the horizontal portion 612.

[0038] The driving component 62 can be various types of power devices, such as electric push rods, hydraulic cylinders, etc. In this embodiment, it is a pneumatic finger cylinder. Specifically, the pneumatic finger cylinder includes a cylinder body 621 fixedly connected to the support plate 44, a guide rail 622 set on the cylinder body 621, and a slider 623 slidably connected to the guide rail 622. There are two sliders 623, which are fixedly connected to two vertical parts 613 respectively. Specifically, the upper surface of the slider 623 is provided with a connecting part 624 parallel to the length direction of the horizontal part 612.

[0039] Back Figure 1 , Figure 2 Furthermore, a first protective cover 12 is provided on the frame 1 to shield the portion of the first drive assembly 3 and the support assembly 4 located below the turntable 2. A second protective cover 46 is also provided to protect the fixing plate 43 and the support plate 44.

[0040] Reference Figure 2 , Figure 4 The support plate 44 is provided with a platform 47 for placing the ampoule 11. The platform 47 is tilted at a certain predetermined angle relative to the horizontal plane, and its tilt direction is close to the axis of the turntable 2. The upper surface of the platform 47 is provided with a placement groove 471, and the cylinder 621 is provided with a mounting bracket 472 for installing the platform 47.

[0041] Furthermore, since the liquid in the ampoule 11 is initially injected through a syringe, a pinhole will be left on the top of the ampoule 11. During the shaking process, it may be subjected to a vertical force to flow out from the pinhole. In this embodiment, a liquid collection tank 48 is provided above the second protective cover 46. The liquid collection tank 48 is convex. The top of the liquid collection tank 48 is reserved with a first through groove 481 for the platform 47 to pass through, and second through grooves 482 are provided on both sides for the connecting part 624 to pass through.

[0042] It should be noted that, in order to improve the shaking efficiency, the size of the turntable 2 can be increased. In this case, the bearing component 4, the second drive component 5 and the clamping component 6 are arranged at intervals around the axis of the turntable 2, so that multiple ampoules 11 can be shaken.

[0043] The implementation principle of the bottle liquid shaking mechanism based on a cylinder in this application embodiment is as follows: the first driving component 3 drives the turntable 2 to perform intermittent rotational motion, which, in conjunction with the operation of the vertical cylinder 51, drives the clamping component 6 to perform vertical movement, which can more effectively shake the liquid in the ampoule 11. Compared with the traditional manual shaking method, the efficiency is greatly improved. Moreover, the component has a relatively simple structure and low cost, making it suitable for use in small and medium-sized institutions.

[0044] Example 2: Reference Figure 5 , Figure 6 The difference from Embodiment 1 is that a rotating rod 625 is rotatably connected to the surface of the connecting part 624 near the vertical part 613, and the vertical part 613 of the gripper 61 is connected to the rotating rod 625. A control member 7 is provided on the support plate 44, which is used to drive the gripper 61 to swing as the vertical cylinder 51 rises and falls.

[0045] In this embodiment, the control component 7, as shown in the figure, specifically includes a control rope 71 connected to the horizontal part 612 / clamping part 611 and a torsion spring 72 coaxially sleeved on the rotating rod 625. The other end of the control rope 71 is connected to the piston rod / fixed plate 43 of the vertical cylinder 51. The two ends of the torsion spring 72 are respectively fixedly connected to the connecting part 624 and the vertical part 613. The torsion spring 72 is used to drive the gripper 61 to reset. In order to adapt to the gripper 61 to drive the ampoule 11 to rotate, the placement platform is rotatably connected to the mounting frame 472.

[0046] The control rope 71 can be a high-strength rope, such as a steel wire rope, to ensure that it can withstand a certain amount of tension. It can also be an elastic rope to provide cushioning during the swinging process and reduce excessive impact on the gripper 61 and related components. The elastic coefficient of the torsion spring 72 is selected according to actual needs to ensure that the gripper 61 can be reset smoothly.

[0047] Example 3: Reference Figure 7 , Figure 8 The difference from Embodiment 1 is that, in this embodiment, in order to reduce the possibility of the ampoule 11 shaking or falling off during the swinging of the gripper 61, an elastic layer 8 is provided on the surface of the gripping part 611 near the medicine bottle. The elastic layer 8 has a cavity 81. A through groove 614 communicating with the cavity 81 is opened on the surface of the gripping part 611 near the elastic layer 8. The gripper 61 is slidably connected to the piston 615 in the through groove 614. The through groove 614 and the cavity 81 are filled with a medium. The control rope 71 passes through the horizontal part 612 / gripping part 611 to connect with the piston 615. The length of the through groove 614 is less than the arc length of the swing of the gripper 61. When the control rope 71 drives the gripper 61 to swing, it drives the piston 615 to move towards the elastic layer 8, so as to expand the elastic layer 8 and squeeze the ampoule 11.

[0048] Specifically, regarding how the control rope 71 drives the piston 615 to move towards the elastic layer 8, a slide rod 9 is provided at the end of the piston 615 away from the elastic layer 8. The slide rod 9 includes a fixed part 91 connected to the piston 615 and a moving part 92 provided perpendicular to the fixed part 91. The length direction of the moving part 92 is parallel to the moving path of the piston 615. Correspondingly, the gripper 61 has a first sliding groove 616 for the fixed part 91 to slide and a second sliding groove 617 for the moving part 92 to slide and connect. The control rope 71 is fixedly connected to the end of the slide rod near the piston rod.

[0049] Furthermore, the surface of the elastic layer 8 near the ampoule 11 is provided with anti-slip texture 82.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
