Specific embodiments

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0031] As used herein, "one embodiment" or "an embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present application. In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. Moreover, the terms "first", "second", etc. are used to distinguish similar objects and do not necessarily have to be 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 described herein can be implemented in an order other than those illustrated or described herein.

[0032] During the reaction process or separation and treatment stage of pharmaceutical chemical synthesis, when adding reagents or extractants to the reaction solution, there is a possibility of liquid splashing. For manual operation of the reaction, there are threats to direct and indirect personal safety and environmental pollution; for automated operation of the reaction, in addition to environmental pollution, there are other devices or equipment around the operation site, which will cause damage to the automated equipment and secondary pollution. In order to address the problem of liquid splashing, a relatively common method is to take anti-splashing measures during manual operation, mainly protective clothing and protective masks, which belong to passive protection. It is necessary to fully consider the possibility and harm of liquid splashing, and it cannot solve the problem of environmental pollution. There are certain potential safety hazards to personal safety. In addition, it has relatively high requirements for personnel quality, and requires personnel to complete the dropping action in a timely manner and evacuate to a safe area, which cannot meet the requirements of automated reactions. Another method is to open the original auxiliary material packaging and place it on the feed tank, and the materials are transported into the reaction kettle by a screw feeder. However, for different reaction or extraction operations, different feeders need to be configured, and a flushing device needs to be configured to prevent cross-contamination, which will bring problems of complex structure, large floor area, and low production efficiency.

[0033] In order to meet the requirements of automated pharmaceutical chemical synthesis experiments, the present application provides a splash-proof device that can achieve fully automated and unmanned liquid addition operations, ensure the safety of the experimental process, reduce pollution, and at the same time the automated process can improve production efficiency.

[0034] Reference Figure 1 , which shows a schematic structural diagram of the splash-proof device of the present application. The splash-proof device includes a base 1, a material storage mechanism 2, a driving mechanism 3, and a splash-proof mechanism 4.

[0035] Among them, the material holding mechanism 2 is placed on the base; the material holding mechanism 2 includes a preset number of reaction vessels 21.

[0036] Specifically, the base 1 has a platform with a certain area for placing the material holding mechanism 2. The material holding mechanism 2 includes a preset number of reaction vessels 21, and the reaction vessels 21 are used to hold reagents, and the reagents include but are not limited to reaction agents, extractants, etc. used in pharmaceutical chemical synthesis reactions. The size specifications of the reaction vessels 21 can be the same or different, and multiple reaction vessels 21 can be combined and set, such as test tubes, beakers, flasks, etc., which are specifically set according to the actual situation. In some embodiments, the preset number of reaction vessels 21 is 3. It should be noted that the preset number and size specifications of the reaction vessels 21 can be set according to the requirements of actual operations and are not limited herein. This can improve the adaptability and throughput of reagents in pharmaceutical chemical synthesis reactions.

[0037] In a possible implementation manner, the base 1 has a receiving groove 11; the material holding mechanism 2 is placed in the receiving groove 11.

[0038] Specifically, the receiving groove 11 of the base 1 has a certain depth, and the top surface of the receiving groove 11 in the vertical direction is an open end. The material holding mechanism 2 is placed in the receiving groove 11. In some embodiments, the material holding mechanism 2 can be placed at one end of the receiving groove 11.

[0039] In a possible implementation manner, the material holding mechanism 2 further includes a mounting module 22, and a preset number of reaction vessels 21 are mounted in the mounting module 22.

[0040] Specifically, the mounting module 22 is fixed in the receiving groove 11 of the base 1. The mounting module 22 includes at least one mounting position, and each mounting position is adapted to the size specification of the reaction vessel 21. A preset number of reaction vessels 21 are clamped in each mounting position of the mounting module 22. This can ensure the stability of the reaction vessels 21 and prevent liquid from pouring.

[0041] The driving mechanism 3 is connected to the anti-splash mechanism 4. The driving mechanism 3 is used to drive the anti-splash mechanism 4 to move horizontally on the base 1 to approach or move away from the material holding mechanism 2. The anti-splash mechanism 4 includes a housing 41. When the anti-splash mechanism 4 moves to the target position corresponding to the material holding mechanism 2, the material holding mechanism 2 is received in the housing 41; the housing 41 is used to block the reagents splashed during feeding or reaction.

[0042] Specifically, continue to refer to Figure 1 As shown, the anti-splash mechanism 4 includes a housing 41. The bottom edge of the housing 41 is connected to the base 1. The housing 41 and the receiving groove 11 can form a semi-closed space. When the anti-splash mechanism 4 moves to the target position corresponding to the material holding mechanism 2, refer to Figure 2As shown, the material holding mechanism 2 is accommodated in the bin body 41. When the material holding mechanism 2 is accommodated in the bin body 41, a specified volume of reagent is added to the reaction vessel 21 for reaction or extraction. If there is reagent splashing during the feeding or reaction process, the bin body 41 is used to block the splashing reagent, and then the splashing reagent will flow into the base 1. Further, the splashing reagent will flow into the receiving groove 11.

[0043] The anti-splash mechanism 4 is driven by the driving mechanism 3 to move horizontally on the base 1. When starting the operation, the driving mechanism 3 is turned on, and the anti-splash mechanism 4 is first reset, that is, the anti-splash mechanism 4 is driven to move to a position far from the material holding mechanism 2 on the base 1. The robotic arm clamps the reaction vessel 21 that needs to be extracted or filled with liquid to the corresponding installation position of the installation module 22, and then prepares for feeding. After the feeding is completed, the driving mechanism 3 drives the anti-splash mechanism 4 to move to a position close to the material holding mechanism 2, blocking the material holding mechanism 2 from the surrounding environment and blocking the reagent splashing during the reaction.

[0044] In a possible implementation manner, the driving mechanism 3 includes a motor and a driving rod 31. The anti-splash mechanism 4 is connected to the driving rod 31. Based on the driving force provided by the motor, the driving rod 31 drives the anti-splash mechanism 4 to move horizontally on the base 1. Specifically, the extending direction of the driving rod 31 is the horizontal direction. The anti-splash mechanism 4 is connected to the driving rod 31, and the driving rod 31 drives the anti-splash mechanism 4 to move horizontally on the base 1, approaching or moving away from the material holding mechanism 2. In some embodiments, the driving mechanism 3 is arranged on the other side of the base 1 relative to the material holding mechanism 2. Initially, the anti-splash mechanism 4 can be located at a position close to the driving mechanism 3 and far from the material holding mechanism 2. Then, after the feeding is completed, the anti-splash mechanism 4 is driven by the driving rod 31 to move horizontally on the base 1 to a position far from the driving mechanism 3 and close to the material holding mechanism 2.

[0045] In a possible implementation manner, the anti-splash mechanism 4 is slidably connected to the first side and the second side of the base 1. Under the driving action of the driving mechanism 3, the anti-splash mechanism 4 slides horizontally along the first side and the second side of the base 1.

[0046] Specifically, the movement mode of the anti-splash mechanism 4 on the base 1 is sliding. The bottom edge of the bin body 41 of the anti-splash mechanism 4 is slidably connected to the first side and the second side of the base 1. Further, in a possible implementation manner, horizontal slide rails 12 are respectively arranged on the first side and the second side of the base 1. The anti-splash mechanism 4 is provided with sliders that cooperate with the slide rails 12. The anti-splash mechanism 4 slides horizontally along the first side and the second side of the base 1 through the cooperation of the sliders and the slide rails 12.

[0047] Specifically, the first side and the second side of the base 1 are parallel to the sliding direction of the anti-splash mechanism 4. Slide rails 12 are respectively provided on the first side and the second side of the base 1. The slide rails 12 can be convex slide rail structures or concave slide rail structures; the anti-splash mechanism 4 is provided with sliders that cooperate with the slide rails 12. The sliders can be groove structures or convex structures. The anti-splash mechanism 4 slides horizontally along the first side and the second side of the base 1 through the cooperation of the sliders and the slide rails 12. That is, when the slide rail 12 is a convex slide rail structure, the slider is a groove structure to cooperate with it; when the slide rail 12 is a concave slide rail structure, the slider is a convex structure to cooperate with it. After the slide rails 12 are installed for the first time, the horizontal movement direction of the anti-splash mechanism 4 can be fixed, ensuring the precise docking of the anti-splash mechanism 4 with the reaction vessel 21.

[0048] Reference Figure 3 As shown, in a possible implementation manner, a first positioning sensor 5 and a second positioning sensor 6 are provided on the base 1; wherein, the first positioning sensor 5 is used to position the anti-splash mechanism 4 at a first preset position on the slide rail 12; the first preset position is far from the material loading mechanism 2; the second positioning sensor 6 is used to position the anti-splash mechanism 4 at a second preset position on the slide rail 12; the second preset position is close to the material loading mechanism 2.

[0049] Specifically, a first positioning sensor 5 and a second positioning sensor 6 are arranged on the base 1. The first positioning sensor 5 and the second positioning sensor 6 are both on the same side. In some embodiments, the first positioning sensor 5 and the second positioning sensor 6 are arranged below the slide rail 12, and the connection line of the first positioning sensor 5 and the second positioning sensor 6 is parallel to the slide rail 12. The first positioning sensor 5 is far from the material loading mechanism 2, and the second positioning sensor 6 is close to the material loading mechanism 2. The first positioning sensor 5 is used to position the anti-splash mechanism 4 at the first preset position on the slide rail 12, and the second positioning sensor 6 is used to position the anti-splash mechanism 4 at the second preset position on the slide rail 12.

[0050] It can be understood that the position where the first positioning sensor 5 is located corresponds to the first preset position of the anti-splash mechanism 4 on the slide rail 12, and the position where the second positioning sensor 6 is located corresponds to the second preset position of the anti-splash mechanism 4 on the slide rail 12. In some embodiments, the first preset position is used as the starting point for the anti-splash mechanism 4 to slide on the base 1, and the second preset position is used as the ending point for the anti-splash mechanism 4 to slide on the base 1. The starting point and the ending point can be understood as the relative starting point and ending point during the anti-splash operation of the anti-splash mechanism 4.

[0051] When starting the operation, based on the driving force provided by the motor, the driving rod 31 drives the anti-splash mechanism 4 to move to the first preset position of the slide rail 12 first. The robotic arm clamps the reaction vessel 21 that needs to be extracted or filled with liquid to the corresponding installation position of the installation module 22, and then prepares for feeding. The driving mechanism 3 drives the anti-splash mechanism 4 to move to the second preset position. The storage body 41 and the receiving groove 11 can form a semi-closed space, and the material storage mechanism 2 is accommodated in the semi-closed space. Each feeding port 42 corresponds to the reaction vessel 21 one by one.

[0052] In this way, the movement position of the anti-splash mechanism 4 on the base 1 can be accurately positioned, avoiding interference when the robotic arm places and grabs the reaction vessel 21, and also ensuring the accuracy of liquid addition and blocking the splashed reagent during feeding, restricting the range of splashed liquid, avoiding the impact of experimental safety on the human body, and reducing environmental pollution.

[0053] In a possible implementation manner, the anti-splash mechanism 4 is provided with a positioning member 43, and the first positioning sensor 5 and the second positioning sensor 6 identify the positioning member 43 to position the anti-splash mechanism 4 sliding to the first preset position or the second preset position.

[0054] Specifically, the positioning member 43 of the anti-splash mechanism 4 is arranged on the slider on the side where the first positioning sensor 5 and the second positioning sensor 6 are located. The positioning member 43 has an identification function and can be identified by the first positioning sensor 5 and the second positioning sensor 6. For example, in some embodiments, the first positioning sensor 5 and the second positioning sensor 6 are magnetic position sensors, and the positioning member 43 is a magnet. When the positioning member 43 follows the anti-splash mechanism 4 and approaches the first positioning sensor 5 / second positioning sensor 6, a magnetic field will be generated, and the Hall element of the first positioning sensor 5 / second positioning sensor 6 will generate a voltage signal proportional to the magnetic field strength, thereby determining the position of the anti-splash mechanism 4 on the slide rail 12. The types and working methods of the first positioning sensor 5, the second positioning sensor 6, and the positioning member 43 can be set according to the actual situation and are not limited herein.

[0055] In a possible implementation manner, at least one feeding port 42 is provided at the top of the storage body 41 of the anti-splash mechanism 4; for adding reagents to the corresponding reaction vessel 21 through the feeding port 42.

[0056] Specifically, at least one feeding port 42 is opened at a preset position on the top of the storage body 41 of the anti-splash mechanism 4. For example, a feeding port 42 is opened at the geometric center of the top of the storage body 41, or feeding ports 42 corresponding to the number and positions of the reaction vessels 21 can also be opened at other positions on the top of the storage body 41.

[0057] When a feeding port 42 is opened, the anti-splash mechanism 4 can be slid to align the feeding port 42 with one of the reaction vessels 21, and reagents are added to the corresponding reaction vessel 21 through the feeding port 42. Then, the anti-splash mechanism 4 is slid again to align the feeding port 42 with other reaction vessels 21, and reagents are added to the corresponding reaction vessels 21 through the feeding port 42, and so on.

[0058] When feeding ports 42 corresponding to the number and positions of the reaction vessels 21 are opened, the anti-splash mechanism 4 is driven to move to a target position corresponding to the material holding mechanism 2. As shown in Figure 2 the figure, the material holding mechanism 2 is accommodated in a semi-closed space. The feeding ports 42 correspond to the reaction vessels 21 one by one. Specified volumes of reaction reagents are added to the corresponding reaction vessels 21 through the feeding ports 42. If reaction reagents splash during the feeding process, the housing 41 of the anti-splash mechanism 4 can block the splashing reaction reagents, and then the splashing reaction reagents will flow into the base 1 and further into the receiving groove 11.

[0059] In a possible implementation, a liquid collecting groove 44 is provided at the top of the housing 41 of the anti-splash mechanism 4, and at least one feeding port 42 is opened in the liquid collecting groove 44. When reagents are added to the corresponding reaction vessels 21 through the feeding ports 42, the liquid collecting groove 44 is used to collect the reagents splashed outside the feeding ports 42.

[0060] Specifically, the top of the housing 41 of the anti-splash mechanism 4 is recessed to form the liquid collecting groove 44, and at least one feeding port 42 is opened at a preset position in the liquid collecting groove 44. For example, a feeding port 42 is opened at the geometric center of the liquid collecting groove 44, or feeding ports 42 corresponding to the number and positions of the reaction vessels 21 can also be opened at other positions in the liquid collecting groove 44.

[0061] When reagents are added to the corresponding reaction vessels 21 through the feeding ports 42, reagents may also splash at the feeding ports 42, and then the splashing reagents will fall into the liquid collecting groove 44. Therefore, in some embodiments, the feeding ports 42 are located in the middle of the liquid collecting groove 44 to ensure that the liquid collecting groove 44 can cover the splashing range of the reagents as much as possible.

[0062] In a possible implementation, at least one overflow port 45 is also opened in the liquid collecting groove 44, and the edge of each overflow port 45 is lower than the horizontal plane of the liquid collecting groove 44, so that the reagents collected in the liquid collecting groove 44 are discharged through the overflow ports 45.

[0063] Specifically, the edge of the overflow port 45 is lower than the horizontal plane of the liquid collection tank 44, which is conducive to the reagent collected in the liquid collection tank 44 being discharged through the overflow port 45 under the action of gravity. For the discharge method, in a possible implementation, the overflow port 45 communicates with the accommodation tank 11, and the reagent collected in the liquid collection tank 44 directly flows into the accommodation tank 11 through the overflow port 45. In some embodiments, there are 4 overflow ports 45, which are distributed at the four corners of the liquid collection tank 44, so as to ensure that the reagent collected in the liquid collection tank 44 can flow into the accommodation tank 11 as much as possible. In other embodiments, the overflow port 45 can also be arranged near the feeding port 42, and each feeding port 42 corresponds to two overflow ports 45. The number and position of the overflow ports 45 can be set according to the actual situation and are not limited here.

[0064] For the discharge method, in another possible implementation, one end of a conduit is connected to each overflow port 45, and the other end of the conduit is connected to an external collection device. The reagent collected in the liquid collection tank 44 is discharged to the external collection device through the overflow port 45 and then through the conduit.

[0065] In a possible implementation, a liquid discharge port 13 is provided at the bottom of the base 1, and the liquid discharge port 13 is used to discharge the reagent in the accommodation tank 11.

[0066] Specifically, the liquid discharge port 13 is located at the bottom end of the accommodation tank 11 of the base 1, and the splashed reagent in the accommodation tank 11 can be discharged through the liquid discharge port 13. The splashed reagent includes the reagent blocked by the bin body 41 splashed at the mouth of the reaction vessel 21, and the reagent collected by the liquid collection tank 44 splashed at the feeding port 42. This ensures the directional discharge and collection of the waste liquid to avoid environmental pollution.

[0067] In summary, in the present application, a movable anti-splash mechanism is externally arranged around the reaction vessel. The anti-splash mechanism includes a bin body and a feeding port corresponding to the reaction vessel. The driving mechanism is used to drive the anti-splash mechanism to move horizontally on the base. When adding reagents to the corresponding reaction vessels through each feeding port, the bin body is used to block the splashed reagent during the feeding process. The first positioning sensor and the second positioning sensor are used to accurately position the movement position of the anti-splash mechanism on the base, avoiding interference when the robotic arm places and grabs the reaction vessel, and also ensuring the accuracy of liquid addition and blocking the splashed reagent during feeding, restricting the range of splashed liquid. The liquid collection tank and the overflow port can collect the reagent splashed at the feeding port 42 and, together with the reagent in the accommodation tank, are discharged directionally through the liquid discharge port, avoiding the impact on personal safety in the experiment and reducing environmental pollution. The whole process is automated and unmanned, improving production efficiency while ensuring personal safety.

[0068] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
