[0035] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0036] In the embodiments of this utility model, words such as "exemplarily" and "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" in this utility model should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present the concept in a concrete manner. Furthermore, in the embodiments of this utility model, the meaning expressed by "and / or" can be both, or it can be either one or the other.

[0037] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0038] This utility model embodiment provides a clamping fixture for a liquid preparation station. Figure 1 This is one of the structural schematic diagrams of a liquid preparation station clamping fixture provided in an embodiment of this utility model. Please refer to [the diagram]. Figure 1 The clamping fixture includes: a tray body 1 and multiple medicine bottle clamps 2; the tray body 1 is provided with a liquid bag receiving position 11 and multiple recesses, each recess being provided with a medicine bottle clamp 2; wherein, at least one medicine bottle clamp 2 includes a housing 21, multiple elastic pieces 22 and multiple stops 23 corresponding to the multiple elastic pieces 22, the fixed ends of the elastic pieces 22 and the stops 23 are uniformly arranged circumferentially on the inner wall of the housing 21, the free ends of the elastic pieces 22 extend into the inner cavity of the housing 21, the free ends of the elastic pieces 22 abut against the stops 23, and a limiting space is formed between the multiple free ends.

[0039] Specifically, the tray body 1 serves as a carrier, integrating a liquid bag receiving position 11 for placing the liquid bag A and multiple recesses for embedding and installing the medicine bottle clamp 2, which can centrally place the liquid bag A and medicine bottle B in a prescription, facilitating standardization.

[0040] Specifically, each vial clamp 2 is used to support the parallel processing of multiple types of vials B. The vial clamp 2 can be easily removed from the recess for replacement. The combination structure of the elastic sheet 22 and the stop 23 enables adaptive clamping of the vial B.

[0041] The multi-directional elastic sheet 22 design effectively ensures the clamping force between the medicine bottle and the clamp, while also featuring an automatic centering function for accurate positioning. This reduces the difficulty of handling medicine bottle B and is compatible with various cylindrical packaging medicine bottles B, such as ampoules and vials of different sizes. Manual handling of medicine bottle B is also simple. This design solves the problem of poor compatibility between liquid bag A and medicine bottle B specifications in traditional equipment, requiring frequent clamp changes. In other words, this design achieves efficient compatibility between multiple types of medicine bottles B and liquid bags A through standardized clamps.

[0042] The fixed ends of the aforementioned elastic plates 22 are arranged at equal angles along the circumference of the shell 21 to ensure uniform radial force and avoid local deformation of the container. For example, the number of elastic plates 22 can be 3-6, and this embodiment does not limit this.

[0043] The free end contacts the stop portion 23 under elastic action, forming an adjustable annular clamping area that is compatible with medicine bottles B of different diameters. Moreover, the elastic sheet 22 can be made of medical-grade silicone or thermoplastic elastomer (TPE), which has both biocompatibility and fatigue resistance.

[0044] The liquid dispensing station clamping fixture provided by this utility model, by setting multiple medicine bottle clamps 2 and liquid bag receiving positions 11 on the tray body 1, can accommodate medicine bottles B and liquid bags A of the same prescription. Furthermore, the medicine bottle clamps 2 include a shell 21, multiple elastic pieces 22, and multiple stops 23 corresponding to the elastic pieces 22, forming a limiting space between the free ends of the elastic pieces 22 for clamping medicine bottles B of different sizes. The free ends of the elastic pieces 22 abut against the stops 23, thereby strengthening the elastic clamping force. Through modular design, different specifications of medicine bottles B or liquid bags A can be accommodated without frequent clamp replacement, improving production continuity.

[0045] In one embodiment of the present invention, the pallet body 1 includes a bottom plate 12 and a top plate 13 detachably disposed on the bottom plate 12. The top plate 13 and the bottom plate 12 have a preset distance between them, and the top plate 13 is provided with a plurality of through holes 131, which form the above-mentioned recesses with the corresponding lower space.

[0046] Specifically, the base plate 12 and the top plate 13 can be connected by snap-fit ​​or bolts to form a detachable modular assembly. A preset distance can be designed according to commonly used medicine bottle B specifications; for example, it can be an adjustable distance of 5-50mm from the base plate 12. The surface is provided with an array of through holes 131, the shape of which matches the shape of the medicine bottle clamp 2. For example, the shape of the through holes 131 and the medicine bottle clamp 2 can be circular, elliptical, or polygonal.

[0047] Furthermore, an elastic pad made of silicone or polyurethane can be added to the inner wall of the through hole 131 to achieve flexible fixation of the medicine bottle clamp 2.

[0048] Compared to traditional integrated pallets, this structure improves space utilization and shortens module replacement time.

[0049] Figure 2 This is the second structural schematic diagram of a liquid preparation station clamping fixture provided in this embodiment of the present invention. Please refer to [the original text]. Figure 2 Furthermore, the bottom plate 12 or side of the tray body 1 can also be equipped with RFID (Radio Frequency Identification) cards 14 to facilitate the storage of prescription information and identification.

[0050] Figure 3 This is a schematic diagram of the structure of a medicine bottle clamp 2 of a liquid preparation station clamping fixture provided in this embodiment of the present invention. Please refer to [the diagram]. Figure 3In one embodiment of this utility model, the housing 21 of the above-mentioned medicine bottle clamp 2 includes a cylindrical outer wall and a support plate disposed at the bottom of the outer wall. The cylindrical outer wall matches the shape of commonly used medicine bottles, which facilitates the installation of the elastic sheet 22 and the stop, and the support plate at the bottom is used to remove the medicine bottle B.

[0051] In one embodiment of this invention, each elastic piece 22 has a guide slope 221 at the top of its free end. This slope design eliminates the risk of bite at right-angled edges. When the robotic arm grasps the medicine bottle and inserts it into the medicine bottle clamp 2, the slope guides the neck of the medicine bottle to automatically align with the clamp 2. When the robotic arm grasps the medicine bottle and leaves the clamp 2, the slope of the elastic piece 22 gradually separates from the medicine bottle B packaging, preventing sudden release that could cause the medicine bottle B to shake or fall off. This structure facilitates multi-directional holding force on cylindrical items, ensuring a constant clamping center position, and facilitates the placement of the medicine bottle B. It also offers good compatibility with different sizes of vials and ampoules.

[0052] In one embodiment of this utility model, an anti-slip pad is provided on the liquid bag receiving position 11. The anti-slip pad has anti-slip patterns to prevent the liquid bag A from sliding during movement. Specifically, the anti-slip pad can be made of rubber, and the anti-slip patterns can include: figure-eight shapes, dot shapes, etc.

[0053] In this embodiment, the opening of liquid bag A has various specifications, making it difficult to use the same moving part 4 to grasp liquid bags A of different specifications. Figure 4 This is one of the schematic diagrams of the combined structure of a liquid bag clamp 3 and a liquid bag A in a liquid preparation station clamping fixture provided by this utility model embodiment; Figure 5 This is the second schematic diagram of a combination structure of a liquid bag clamp 3 and a liquid bag A in a liquid preparation station clamping fixture provided in this embodiment of the present invention; Figure 6 This is the third schematic diagram of the combined structure of a liquid bag clamp 3 and a liquid bag A in a liquid preparation station clamping fixture provided in this embodiment of the present invention. Please refer to [the diagram]. Figures 3-5 In any of the above embodiments provided by this utility model, the clamping fixture further includes a liquid bag clamp 3, one side of which has a groove 31 for locking the liquid outlet of the liquid bag A. The liquid bag clamp 3 clamps onto the liquid bag A and moves with the liquid bag A during the liquid dispensing process, facilitating gripping by the moving part 4 and improving the gripping speed of the liquid bag A. The combination of the liquid bag clamp 3 and the liquid bag A improves interchangeability, and through standardized design, ensures a high degree of consistency in mass-produced parts.

[0054] Furthermore, in this embodiment, the outlet portion of the liquid bag A is made of a relatively hard material, which facilitates fixation. In one embodiment provided by this utility model, a screw hole perpendicular to the sidewall is provided on the inner sidewall of the groove 31, and a plunger screw 32 is provided in the screw hole. By abutting against the outlet of the liquid bag A, the liquid bag A can be fixed and prevented from falling out. This structure can be adapted to liquid bags A of different manufacturers and specifications.

[0055] Furthermore, Figure 7 This is a schematic diagram of the combined structure of the movable part 4 and the liquid bag A of the clamping fixture in the liquid preparation station according to an embodiment of this utility model. Please refer to [the diagram]. Figure 7 In one embodiment of this utility model, a locking groove 33 is provided on the side end of the liquid bag clamp 3; the clamping fixture also includes a movable component 4, which is independently disposed from the tray body 1, and includes a gripper 41 corresponding to the locking groove 33. Through this movable component 4, the liquid bag A can be moved to the liquid bag receiving position 11 on the tray body 1, or removed from the tray body 1. Specifically, the movable component 4 can be a multi-axis robotic arm, which will not be elaborated in this embodiment.

[0056] The gripper 41 on the movable part 4 matches the locking groove 33, which facilitates quick gripping of the liquid bag clamp 3.

[0057] For different liquid bags A, a specific liquid bag clamp 3 is developed, corresponding to a specific slot 31. A plunger screw 32 is used to tighten the head of the liquid bag A to prevent the head of the liquid bag A from separating from the liquid bag clamp 3 during the transportation process. The external dimensions of these liquid bag clamps 3 are consistent, which facilitates the gripper 41 of the moving part 4 to clamp and position the workstation.

[0058] Furthermore, in one embodiment of this invention, the movable component 4 also includes multiple vacuum suction cups 42. Each suction cup contains three silicone nozzles arranged in an equilateral triangle, which can be used to suction medicine bottles B, such as liquid bags A, which have a relatively large flat surface, preventing the liquid bag A from shifting or falling off during handling. This solves the problem of inaccurate positioning or falling off due to size differences during the handling of traditional liquid bags A. Specifically, the suction cup can be a vacuum suction cup 42.

[0059] Silicone, with its excellent flexibility, abrasion resistance, and corrosion resistance, can adapt to objects of different shapes and surfaces while ensuring durability over long periods of use. Silicone suction nozzles form a tight seal upon contact with objects, thereby enhancing the vacuum adsorption effect.

[0060] The three silicone nozzles are arranged in an equilateral triangle, which enhances the stability of the suction cup from a mechanical perspective. This equilateral triangular structure ensures that regardless of the direction in which the target object is subjected to external force, the suction cup can distribute the force evenly through the three nozzles, preventing detachment or damage caused by excessive force at a single point. Furthermore, this arrangement helps maintain balance when adsorbing objects of different sizes and shapes.

[0061] When the vacuum suction cup 42 is activated, a negative pressure is generated through its internal vacuum pump system, causing the silicone nozzle to adhere tightly to the surface of the target object, forming a vacuum seal. As the negative pressure increases, the suction cup firmly adheres to the object, thus creating a highly efficient and stable suction capability, allowing the pickup unit to move the object. Whether the object is flat or curved, or even has a surface with minute irregularities, it can be reliably picked up by the vacuum suction cup 42, greatly improving production efficiency and product quality.

[0062] In one embodiment of this invention, the clamping fixture further includes a plurality of fixing slots 5, each fixing slot 5 matching the bottom shape of the medicine bottle B to be fixed. This structure is used to directly fix medicine bottles B of a specific shape or size that exceed the aforementioned medicine bottle clamp 2.

[0063] The liquid dispensing station clamping fixture provided by this utility model, by setting multiple medicine bottle clamps 2 and liquid bag receiving positions 11 on the tray body 1, can accommodate medicine bottles B and liquid bags A of the same prescription. Furthermore, the medicine bottle clamps 2 include a shell 21, multiple elastic pieces 22, and multiple stops 23 corresponding to the elastic pieces 22, forming a limiting space between the free ends of the elastic pieces 22 for clamping medicine bottles B of different sizes. The free ends of the elastic pieces 22 abut against the stops 23, thereby strengthening the elastic clamping force. Through modular design, different specifications of medicine bottles B or liquid bags A can be accommodated without frequent clamp replacement, improving production continuity.
