Description

Technical Field

[0001] The present invention relates to the technical field of solution preparation, and specifically to an ampoule bottle opening device and a dilution and labeling instrument. Background Art

[0002] An ampoule bottle is a small sealed container for holding solutions, usually made of glass, with high sealing performance and sterility, and is widely used in the fields of medical treatment and laboratory testing. Due to the extremely strong sealing performance of the ampoule bottle, when opening the cap, it is necessary to ensure the safety of the operation and avoid glass fragments contaminating the solution. Therefore, opening the cap is very troublesome. The existing opening solutions are generally manual opening, which is slow in efficiency and easy to contaminate, and it is difficult to meet the requirements of modern laboratories and unmanned laboratories.

[0003] A Chinese invention patent with the authorization announcement number of CN111960358B, an opening device, especially an ampoule bottle opening device. The technical problem it needs to solve is how to design an ampoule bottle opening device that can open multiple ampoule bottles at one time, improve work efficiency, and save manpower. To solve the above technical problems, such an ampoule bottle opening device is provided, including: a mounting table, on the top of which a sliding frame is slidably connected, and there is a certain frictional force between the sliding frame and the mounting table; a first return spring, which is connected between the sliding frame and the mounting table; a collection frame, which is connected to one side of the mounting table, and an inclined plate is connected to the top of the collection frame; a moving cutting component, which is arranged between the mounting table and the sliding frame; and a pushing component, which is arranged on the mounting table. This solution can achieve the effect of opening the ampoule bottle through the cooperation of the moving cutting component and the pushing component.

[0004] The above patent realizes the automatic opening of the ampoule bottle and saves manpower. However, when the grinding wheel contacts the ampoule bottle, the grinding wheel rotates at a high speed and the relative position between the grinding wheel and the ampoule bottle remains unchanged. This results in that the grinding wheel cannot form a complete circle of scratches on the neck of the ampoule bottle, but only a small section of scratches can be formed at the contact position between the grinding wheel and the ampoule bottle. The function of forming scratches on the ampoule bottle is to control stress concentration and guide the fracture path, converting the original random brittle fracture into a controllable process. Since a complete circle of scratches cannot be formed on the neck of the ampoule bottle, it leads to the inability to accurately control the fracture position of the ampoule bottle during the final opening process, and fragmentation may occur, thereby contaminating the medium such as the solution in the ampoule bottle.

[0005] Based on this, the present invention designs an ampoule bottle opening device to solve the above problems. Summary of the Invention

[0006] The present invention provides an ampoule bottle opening device to solve the technical problem that the existing opening device cannot form a complete circle of scratches on the neck of the ampoule bottle.

[0007] According to one aspect of the present invention, there is provided an ampoule opening device, including a clamping assembly for clamping an ampoule, a cutting assembly for cutting the ampoule, and a knocking assembly for knocking the ampoule. The clamping assembly includes a clamping portion for clamping the ampoule and a rotating portion for driving the clamping portion to rotate. The rotating portion is used to drive the clamping portion to rotate along the axis of the clamped ampoule.

[0008] As a further aspect of the present invention, the cutting assembly includes a clamping jaw, an elastic mounting portion, and a grinding wheel for contacting the ampoule. The grinding wheel is elastically and slidably mounted on the clamping jaw through the elastic mounting portion, and the sliding direction of the grinding wheel is perpendicular to the axis of the grinding wheel.

[0009] As a further aspect of the present invention, the clamping jaw includes a plurality of movable portions, and at least one grinding wheel is provided on a single movable portion. The clamping jaw has a first state for driving the edge of the grinding wheel to contact the position to be cut of the ampoule, and a second state for driving the grinding wheel to disengage from the ampoule. The cutting assembly further includes a driving member for driving the movable portion to move so that the clamping jaw switches between the first state and the second state. The plurality of grinding wheels are arranged at equal intervals or symmetrically in the circumferential direction in the first state of the clamping jaw, so as to uniformly press the ampoule in the circumferential direction or symmetrically press both sides of the ampoule.

[0010] As a further aspect of the present invention, the clamping jaw includes two symmetrically arranged movable portions, and two grinding wheels are mounted on a single movable portion through an elastic mounting portion. The grinding wheels on the two movable portions are symmetrically arranged with respect to the symmetry plane of the two movable portions.

[0011] As a further aspect of the present invention, the elastic mounting portion includes a slide bar, a slider, and a spring. The first end of the slide bar is fixed to the clamping jaw. The slider is slidably arranged on the slide bar along the length direction of the slide bar and is used to mount the grinding wheel. The spring is elastically pressed between the clamping jaw and the slider.

[0012] As a further aspect of the present invention, the clamping portion includes at least two clamping blocks and a clamping motor for driving the clamping blocks to clamp or loosen the ampoule. The rotating portion includes a rotating motor. The clamping motor is arranged on the rotating motor, and the rotating motor is used to drive the clamping motor and the clamping blocks to rotate together.

[0013] As a further aspect of the present invention, the surface of the clamping block for contacting the ampoule is set to an arc surface structure matching the shape of the ampoule body.

[0014] As a further aspect of the present invention, a conductive slip ring is arranged on the rotating motor. The stator of the conductive slip ring is fixedly connected to the outer shell of the rotating motor, and the rotor of the conductive slip ring is connected to the output shaft of the rotating motor and the clamping motor.

[0015] As a further solution of the present invention, the knocking component includes a swing rod and a swing rod motor for driving the swing rod to rotate, and the swing rod is used to knock the ampoule bottle after being cut by the cutting component.

[0016] As a further solution of the present invention, the ampoule bottle opening device further includes an installation tabletop for installing the clamping component, the cutting component and the knocking component, and a waste residue box for storing the ampoule bottle caps is fixedly arranged on the installation tabletop.

[0017] A dilution and labeling instrument includes the above-mentioned ampoule bottle opening device.

[0018] The present invention has the following beneficial effects:

[0019] In this solution, the clamping component includes a clamping part for clamping the ampoule bottle and a rotating part for driving the clamping part to rotate. By driving the clamping part to rotate through the rotating part, the ampoule bottle on the clamping part can be driven to rotate. When the rotating part drives the clamping part to rotate, the rotation axis coincides with the axis of the ampoule bottle, so as to drive the ampoule bottle to rotate self - rotatably through the rotating part. After the grinding wheel contacts the neck of the ampoule bottle, the rotating part drives the ampoule bottle to rotate self - rotatably to generate a circular scratch on the neck of the ampoule bottle. By controlling the fracture path when the ampoule bottle cap and the bottle body break through the circular scratch, it is possible to prevent the uncontrollable fracture path in the latter section from causing fragmentation and reduce the risk of solution contamination.

[0020] In addition to the purposes, features and advantages described above, the present invention has other purposes, features and advantages. The following will refer to the drawings to further elaborate on the present invention in detail. Description of the Drawings

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the following.

[0029] Please refer to Figures 1-4 , the present invention provides a technical solution: an ampoule bottle opening device, including a clamping assembly for clamping the ampoule bottle 9, a cutting assembly for cutting the ampoule bottle 9, and a knocking assembly for knocking the ampoule bottle 9. The clamping assembly includes a clamping portion for clamping the ampoule bottle 9 and a rotating portion for driving the clamping portion to rotate. The rotating portion is used to drive the clamping portion to rotate along the axis of the clamped ampoule bottle 9.

[0030] The ampoule bottle 9 is clamped and fixed by the clamping assembly to ensure the stability of the subsequent cutting and knocking of the ampoule bottle 9. Subsequently, the cutting assembly cuts the neck part of the ampoule bottle 9 to make a scratch at the neck position of the ampoule bottle 9. Then, the knocking assembly knocks the cap position of the ampoule bottle 9, so that the cap of the ampoule bottle 9 breaks from the scratch. Since the ampoule bottle 9 is usually made of glass material, which is a brittle material, a scratch is pre-formed at the neck position of the ampoule bottle 9 to control the stress concentration and guide the fracture path, converting the originally random brittle fracture into a controllable process.

[0031] As Figure 1 shown, in this solution, the clamping assembly includes a clamping portion for clamping the ampoule bottle 9 and a rotating portion for driving the clamping portion to rotate. By driving the clamping portion to rotate by the rotating portion, the ampoule bottle 9 on the clamping portion can be driven to rotate. When the rotating portion drives the clamping portion to rotate, the rotation axis coincides with the axis of the ampoule bottle 9, so as to drive the ampoule bottle 9 to rotate by itself through the rotating portion. After the grinding wheel 5 contacts the neck of the ampoule bottle 9, the rotating portion drives the ampoule bottle 9 to rotate by itself to generate a circular scratch at the neck of the ampoule bottle 9. The fracture path when the cap and the bottle body of the ampoule bottle 9 break is controlled by the circular scratch, preventing the uncontrollable fracture path in the latter section from causing fragmentation and reducing the risk of solution pollution.

[0032] Specifically, the cutting assembly includes a claw 4, an elastic mounting portion, and a grinding wheel 5 for contacting the ampoule bottle 9. The grinding wheel 5 is elastically slidably mounted on the claw 4 through the elastic mounting portion, and the sliding direction of the grinding wheel 5 is perpendicular to the axis of the grinding wheel 5.

[0033] The cutting assembly includes a jaw 4, an elastic mounting portion, and a grinding wheel 5. The grinding wheel 5 is mounted on the cutting assembly through the elastic mounting portion. When the grinding wheel 5 contacts the ampoule bottle 9, the elastic mounting portion will be compressed, which can not only buffer when the grinding wheel 5 contacts the ampoule bottle 9, but also ensure that the grinding wheel 5 closely fits the ampoule bottle 9 and generates a certain pressure at the neck position of the ampoule bottle 9. While the grinding wheel 5 can normally contact the ampoule bottle 9 and generate pressure, the risk of the ampoule bottle 9 being squeezed and broken by the grinding wheel 5 is reduced.

[0034] Specifically, as Figures 2-3 shown, the jaw 4 includes a plurality of movable parts. At least one grinding wheel 5 is provided on a single movable part. The jaw 4 has a first state for driving the edge of the grinding wheel 5 to contact the position to be cut of the ampoule bottle 9, and a second state for driving the grinding wheel 5 to disengage from the ampoule bottle 9. The cutting assembly further includes a driving member 6. The driving member 6 is used to drive the movable part to move so that the jaw 4 can be switched between the first state and the second state. The plurality of grinding wheels 5 are used to be arranged at equal intervals or symmetrically in the circumferential direction in the first state of the jaw 4, so as to uniformly press the ampoule bottle 9 in the circumferential direction or symmetrically press both sides of the ampoule bottle 9.

[0035] The jaw 4 includes a plurality of movable parts. A grinding wheel 5 is provided on each movable part, and the number of grinding wheels 5 on the movable part can be one or more, so that the cutting assembly includes a plurality of grinding wheels 5. The plurality of grinding wheels 5 can contact the ampoule bottle 9 from multiple directions, control the position when the grinding wheel 5 contacts the ampoule bottle 9, and make the grinding wheels 5 be uniformly arranged around the circumference of the ampoule bottle 9 or symmetrically arranged on both sides of the ampoule bottle 9 when cutting the ampoule bottle 9. In this way, when cutting the ampoule bottle 9 with the grinding wheel 5, the ampoule bottle 9 can be uniformly stressed in the circumferential direction or on both sides, so as to prevent the ampoule bottle 9 from shifting during the cutting process, effectively improving the cutting accuracy, ensuring that the scratch lines finally formed on the surface of the ampoule bottle 9 are smooth, and thus ensuring that the crack of the ampoule bottle 9 is neat when finally knocking the ampoule bottle 9, reducing the risk of the ampoule bottle 9 generating fragments and polluting the solution when opening the bottle.

[0036] Since the plurality of grinding wheels 5 contact the ampoule bottle 9 from different angles, and the bottleneck of the ampoule bottle 9 is a position with a smaller diameter of the ampoule bottle 9, after the ampoule bottle 9 is cut, there will be mutual movement interference between the ampoule bottle 9 and the grinding wheel 5. Therefore, the driving member 6 is used to control the movement of the movable part so that the movable parts can move relative to each other, and the jaw 4 can be switched between the first state and the second state. When the ampoule bottle 9 needs to be cut, the driving member 6 can be used to drive the movable part to approach the ampoule bottle 9, so that the jaw 4 is in the first state. When the jaw 4 needs to leave the ampoule bottle 9, the driving member 6 can be used to drive the movable part away from the ampoule bottle 9, so that the grinding wheel 5 disengages from the ampoule bottle 9 and generates a certain gap, so that the jaw 4 can smoothly leave the ampoule bottle 9 or the ampoule bottle 9 can smoothly leave the jaw 4.

[0037] Figures 2-3 An example of the jaw 4 is shown. In this example, the jaw 4 includes two movable parts arranged symmetrically. Two grinding wheels 5 are mounted on a single movable part through elastic mounting parts, and the grinding wheels 5 on the two movable parts are arranged symmetrically with respect to the symmetry plane of the two movable parts;

[0038] With the four grinding wheels 5 arranged in pairs symmetrically, when the ampoule bottle 9 is cut by the grinding wheels 5, the ampoule bottle 9 is clamped between the four grinding wheels 5, and the ampoule bottle 9 is positioned by the four grinding wheels 5, so that the ampoule bottle 9 will not shift during the process of cutting the ampoule bottle 9 by the grinding wheels 5;

[0039] In this example, the driving member 6 is a jaw motor. The two movable parts are mounted on the jaw motor, and the two movable parts are controlled by the jaw motor to approach or separate from each other, thereby adjusting the distance between the grinding wheels 5, so that the grinding wheels 5 contact the ampoule bottle 9 or disengage from the ampoule bottle 9.

[0040] Specifically, as Figure 2 shown, the elastic mounting part includes a slide bar, a slider 3 and a spring 2. The first end of the slide bar is fixedly provided on the jaw 4. The slider 3 is slidably arranged on the slide bar along the length direction of the slide bar and is used for mounting the grinding wheel 5. The spring 2 is elastically pressed between the jaw 4 and the slider 3;

[0041] As Figure 2 shown, a slide bar is provided on the movable part of the jaw 4. A spring 2 and a slider 3 are sleeved on the slide bar. By fixedly mounting the grinding wheel 5 on the slider 3, the grinding wheel 5 can slide along the slide bar. At the same time, the spring 2 is arranged between the slider 3 and the movable part of the jaw 4, so that the spring 2 will be compressed when the grinding wheel 5 approaches the movable part of the jaw 4, so as to achieve buffering when the grinding wheel 5 contacts the ampoule bottle 9 in turn, and prevent the ampoule bottle 9 from being squeezed and broken when contacting the grinding wheel 5;

[0042] Specifically, as Figure 1 shown, the clamping part includes at least two clamping blocks 10 and a clamping motor 11 for driving the clamping blocks 10 to clamp or loosen the ampoule bottle 9. The rotating part includes a rotating motor 13. The clamping motor 11 is arranged on the rotating motor 13, and the rotating motor 13 is used for driving the clamping motor 11 and the clamping blocks 10 to rotate together;

[0043] The clamping blocks 10 are driven by the clamping motor 11 to approach or move away from each other, thereby clamping or loosening the ampoule bottle 9. When the ampoule bottle 9 needs to be cut or struck, first place the ampoule bottle 9 between the clamping blocks 10, and then drive the clamping blocks 10 to approach each other through the clamping motor 11 to clamp the ampoule bottle 9. After the ampoule bottle 9 is clamped, the edge of the grinding wheel 5 in the cutting assembly is attached to the bottleneck of the ampoule bottle 9. Finally, the rotation motor 13 is started to drive the clamping motor 11 and the clamped ampoule bottle 9 on the clamping motor 11 to rotate, so that a complete circular scratch is generated at the bottleneck position of the ampoule bottle 9, making the crack of the ampoule bottle 9 smoother when finally striking the ampoule bottle 9. The rotation of the ampoule bottle 9 is achieved by driving the clamping motor 11 through the rotation motor 13. The overall structure is simple and can be applied to ampoule bottles with different bottle body specifications;

[0044] Specifically, the surface of the clamping block 10 for contacting the ampoule bottle 9 is set as an arc surface structure matching the shape of the bottle body of the ampoule bottle 9. In most cases, the bottle body of the ampoule bottle 9 is cylindrical. Therefore, the surface of the clamping block 10 for contacting the bottle body of the ampoule bottle 9 is circular arc, and the diameter of the circular arc matches the outer diameter of the ampoule bottle 9, so that the clamping block 10 can be in surface contact with the bottle body of the ampoule bottle 9 when clamping the ampoule bottle 9, making the stress area on the surface of the ampoule bottle 9 larger when the clamping block 10 clamps the ampoule bottle 9, and dispersing the clamping force of the clamping block 10 acting on the ampoule bottle 9 to a larger stress surface, thereby further reducing the probability of the ampoule bottle 9 breaking during the bottle opening process.

[0045] Furthermore, a conductive slip ring 12 is provided on the rotation motor 13. The stator of the conductive slip ring 12 is fixedly connected to the outer shell of the rotation motor 13, and the rotor of the conductive slip ring 12 is connected to the output shaft of the rotation motor 13 and the clamping motor 11. The conductive slip ring 12 is a prior art and will not be elaborated here. Through the conductive slip ring 12, normal power supply can be provided to the clamping motor 11 during rotation to ensure the normal operation of the clamping motor 11 during rotation.

[0046] Specifically, the knocking assembly includes a swing rod 7 and a swing rod motor 8 for driving the swing rod 7 to rotate. The swing rod 7 is used to knock the ampoule bottle 9 cut by the cutting assembly;

[0047] The swing rod 7 is driven to rotate by the swing rod motor 8. When a scratch is formed on the neck of the ampoule bottle 9, the swing rod motor 8 drives the swing rod 7 to rotate to knock the cap position of the ampoule bottle 9 through the swing rod 7, so that the cap and the bottle body of the ampoule bottle 9 are disconnected from the scratch at the bottleneck position, and finally the bottle opening of the ampoule bottle 9 is realized. The structure of driving the swing rod 7 by the swing rod motor 8 is simple, more convenient for later maintenance, and has a low production cost at the same time;

[0048] Specifically, the swing rod 7 is a hollow tube made of plastic material, thereby reducing the mass of the swing rod 7 to control the impact force when the swing rod 7 strikes the ampoule bottle 9 and prevent the ampoule bottle 9 from being broken due to a large impact force.

[0049] Furthermore, the ampoule bottle opening device further includes an installation table 14 for installing the clamping assembly, the cutting assembly, and the knocking assembly. A waste residue box 1 for storing the caps of the ampoule bottles 9 is also fixedly provided on the installation table 14.

[0050] As Figure 4 shown, in this example, the clamping assembly, the cutting assembly, and the knocking assembly are all installed on the installation table 14. The clamping assembly is arranged below the installation table 14, and the ampoule bottle 9 is moved into or out of the bottle opening station by the lifting of the clamping assembly. At the same time, the cutting assembly is arranged above the installation table 14 through a lifting device (not shown in the figure), and the grinding wheel 5 is moved closer to or away from the ampoule bottle 9 located at the bottle opening station by the lifting of the cutting assembly. The knocking assembly is fixed on the installation platform and is used to knock the ampoule bottle 9 located inside the bottle opening station.

[0051] During operation, the ampoule bottle 9 is placed between the clamping blocks 10, and the clamping blocks 10 are driven by the clamping motor 11 to move closer to each other to clamp the ampoule bottle 9. Next, the cutting assembly moves closer to the ampoule bottle 9 clamped by the clamping assembly. When the cutting assembly moves, the clamping jaws 4 are in the second state to ensure that the grinding wheel 5 can smoothly move to the same height as the neck of the ampoule bottle 9. After moving into place, the clamping jaws 4 change from the second state to the first state, and the grinding wheel 5 on the clamping jaws 4 approaches the ampoule bottle 9 and contacts the bottleneck position of the ampoule bottle 9. Subsequently, the rotation motor 13 is started to drive the clamping motor 11 and the ampoule bottle 9 to rotate, while the grinding wheel 5 remains stationary, and a relative rotation is generated between the ampoule bottle 9 and the grinding wheel 5 to form a complete circle of scratches at the bottleneck position of the ampoule bottle 9. After the scratch cutting is completed, the rotation motor 13 stops, and at the same time, the clamping jaws 4 return from the first state to the second state. Subsequently, the cutting assembly is lifted by the driving of the lifting device to expose the cap of the ampoule bottle 9. Finally, the swing rod motor 8 is started to drive the swing rod 7 to rotate and knock the ampoule bottle 9, thereby completing the opening of the ampoule bottle 9.

[0052] A waste residue box 1 is also provided on the installation table 14 for collecting the caps of the ampoule bottles 9 knocked off by the swing rod 7. Specifically, the installation position of the waste residue box 1 is determined according to the contact position between the swing rod 7 and the ampoule bottle 9 when the swing rod 7 strikes the ampoule bottle 9 to ensure that the caps of the ampoule bottles 9 separated by the swing rod 7 can smoothly enter the waste residue box 1.

[0053] Preferably, the clamping assembly can be installed on a robotic arm, and the robotic arm is used to drive the clamping assembly to move and rotate, thereby realizing full-automatic feeding and discharging and avoiding hand contact; there is no need to directly contact the ampoule bottle 9 throughout the process, reducing the possibility of microbial contamination and cross-infection.

[0054] Preferably, the cutting assembly can be installed on a robotic arm. The robotic arm drives the cutting assembly to move and rotate. During feeding, the robotic arm moves the cutting assembly above the ampoule bottle. At this time, the clamping jaw 4 is in the second state. Subsequently, the cutting assembly descends under the drive of the robotic arm, causing the clamping jaw 4 to descend to the same height as the bottleneck of the ampoule bottle 9. Then, the clamping jaw motor 6 drives the clamping jaw 4 to change from the second state to the first state. Multiple grinding wheels 5 installed on the clamping jaw 4 contact the ampoule bottle 9 and clamp the ampoule bottle 9, completing the clamping of the ampoule bottle 9. Next, the robotic arm drives the cutting assembly to rise and move above the bottle opening station. At this time, the ampoule bottle 9 clamped by the cutting assembly is located directly above the clamping assembly. Subsequently, the robotic arm drives the cutting assembly to descend, causing the ampoule bottle 9 to descend between the clamping blocks 10. After the ampoule bottle 9 descends in place, the clamping motor 11 drives the clamping blocks 10 to clamp the body of the ampoule bottle 9, completing the full-automatic feeding of the ampoule bottle 9. After the ampoule bottle 9 is opened, the robotic arm drives the cutting assembly to descend, causing the clamping jaw 4 to descend to the same height as the body of the ampoule bottle 9. Then, the clamping jaw motor 6 drives the clamping jaw 4 to change from the second state to the third state. In the third state, the distance between the two clamping jaws 4 is smaller than the second state but larger than the first state. Since the diameter of the body part of the ampoule bottle 9 is larger than that of the bottleneck part, the clamping jaw 4 needs to be changed to the third state when clamping the body part of the ampoule bottle 9 with the grinding wheels 5. After the grinding wheels 5 clamp the ampoule bottle 9, the clamping motor 11 drives the clamping blocks 10 to move away from each other and release the ampoule bottle. Subsequently, the robotic arm drives the cutting assembly to rise, driving the clamped ampoule bottle 9 to rise to achieve automatic discharging. In this way, the cutting assembly can not only achieve precise cutting of the ampoule bottle 9 but also achieve grasping and transferring of the ampoule bottle, thereby reducing the complexity of the equipment, having a simple structure, avoiding hand contact, and not directly contacting the ampoule bottle 9 throughout the process, reducing the possibility of solution contamination.

[0055] A dilution and labeling instrument includes the above-mentioned ampoule bottle opening device. In this solution, the clamping assembly or the cutting assembly is installed on a robotic arm. The full-automatic opening of the ampoule bottle 9 is achieved through the ampoule bottle opening device. After the ampoule bottle 9 is opened, the liquid suction gun of the dilution and labeling instrument transfers the solution in the ampoule bottle 9 to the dilution container of the dilution and labeling instrument, thereby realizing the full-process automation of the solution from the ampoule bottle to the dilution and labeling instrument.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
