Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a drug transfer mechanism. Background Technology

[0002] In the process of drug dispensing, storage and loading, drug storage equipment requires a transfer mechanism to move and transfer drugs. The transfer mechanism uses methods such as clamping and vacuum adsorption to fix the drugs. Vacuum adsorption requires the use of suction cups. However, due to the different shapes and sizes of medicine boxes, especially when the medicine box is small, the commonly used suction cups cannot hold the medicine box well, which may cause the medicine box to fall.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide an improved drug transfer mechanism to enhance the stability of drug transfer.

[0005] To achieve the above objectives, a specific embodiment of this utility model provides a drug transfer mechanism, including an adsorption component and a driving component. The adsorption component includes a plurality of vacuum suction cups connected to external negative pressure devices. Each vacuum suction cup includes a plurality of first suction cups and a third suction cup with an adsorption area greater than the sum of the adsorption areas of the plurality of first suction cups. The driving component connects to and drives the adsorption component to move in the vertical and / or horizontal directions.

[0006] In one or more embodiments of the present invention, the adsorption assembly includes a rectangular base plate, the plurality of first suction cups are disposed at two corners on one side of the base plate along its length, and the third suction cup is disposed on the other side of the base plate.

[0007] In one or more embodiments of this utility model, the third suction cup is a rectangular suction cup, and its long side is parallel to the long side of the base plate.

[0008] In one or more embodiments of this utility model, the first suction cup is a circular suction cup, and the base plate is also provided with a second suction cup with a smaller adsorption area than the first suction cup and also circular, the second suction cup being disposed on one side of the width direction of the third suction cup.

[0009] In one or more embodiments of the present invention, at least the surface of the third suction cup is provided with a sponge, and / or the first suction cup and / or the second suction cup are provided with annular gaskets.

[0010] In one or more embodiments of this utility model, at least a buffer spring is connected between the third suction cup and the base plate.

[0011] In one or more embodiments of the present invention, the adsorption assembly further includes a connecting plate, the connecting plate being connected to the base plate via a telescopic rod, and the driving assembly being connected to the connecting plate.

[0012] In one or more embodiments of the present invention, the driving component includes a first guide rail and a second guide rail arranged vertically, the second guide rail being supported and movable on the first guide rail, and the adsorption component being supported and movable on the second guide rail.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0023] like Figure 1-3 As shown, in one embodiment of this utility model, a drug transfer mechanism 100 is installed in a drug storage device and is used to transfer drug boxes between storage chutes, dosing ports, and dispensing ports via vacuum adsorption. It includes an adsorption component 10 and a driving component 20. The adsorption component 10 includes multiple vacuum suction cups 11 connected to external negative pressure devices, specifically multiple first suction cups 111 and a third suction cup 113 with an adsorption area greater than the sum of the adsorption areas of the first suction cups 111. The driving component 20 connects to and drives the adsorption component 10 to move vertically and / or horizontally, thereby transferring drug boxes between different locations within the device.

[0024] In this embodiment, the drug transfer mechanism 100 does not use a single large-area suction cup. Instead, it uses multiple relatively small vacuum suction cups 11 to increase the total adsorption area and ensure the adsorption effect. This avoids situations where there are not enough suction cups, and the suction cups act on the edge of the medicine box, resulting in insufficient adsorption force and preventing the medicine box from being properly adsorbed and transported.

[0025] Secondly, the vacuum suction cups 11 are of different sizes. The third suction cup 113 serves as the main suction cup and has a larger adsorption area. This is to prevent small medicine boxes from getting stuck in the gap between adjacent vacuum suction cups 11 due to improper application.

[0026] Specifically, the adsorption assembly 10 includes a rectangular base plate 12, all vacuum suction cups 11 are fixed on the base plate 12, the first suction cup 111 is located at two corners on one side of the base plate 12 along its length, and the third suction cup 113 is located on the other side of the base plate 12.

[0027] In one embodiment, the third suction cup 113 is also a rectangular structure, with its long side parallel to the long side of the base plate 12. This arrangement expands the coverage area along the length of the base plate 12, thereby improving the adsorption effect and further reducing the possibility of small-volume medicine boxes getting stuck in the gaps between adjacent vacuum suction cups 11. The length of the third suction cup 113 can be half or more of the length of the base plate 11, and it undertakes the main adsorption action, participating in the adsorption of medicine boxes of all sizes.

[0028] exist Figure 3 In the illustrated embodiment, the first suction cup 111 is a circular suction cup. A second suction cup 112, also circular but with a smaller adsorption area than the first suction cup 111, is also provided on the base plate 12. This second suction cup 112 is located on one side of the third suction cup 113 in the width direction. The three vacuum suction cups 11 work together to cover the area of ​​the base plate 12. The first suction cup 111 is the same size and slightly larger, while the second suction cup 112 is slightly smaller. Both serve as auxiliary suction cups to assist the third suction cup 113 in working together to hold the large medicine box in place and prevent it from falling.

[0029] Preferably, to avoid the third suction cup 113 squeezing the medicine box, causing deformation or even damage, and because its adsorption surface is rectangular, a sponge 16 is provided on the surface of the third suction cup 113 to provide cushioning when in contact with the medicine box, reducing the probability of deformation or damage to the medicine box. This also improves the adhesion to the medicine box surface, ensuring sufficient adsorption even on uneven surfaces.

[0030] It is easy to imagine that annular gaskets 17 are provided on the first suction cup 111 and the second suction cup 112, which are also used to reduce the probability of the medicine box being deformed or damaged when in contact with the medicine box, and at the same time to prevent the uneven or deformed surface of the medicine box from affecting the normal adsorption action.

[0031] Furthermore, since the third suction cup 113 has the highest usage rate, meaning that regardless of the size of the medicine box, this part of the vacuum suction cup 11 will basically participate in the adsorption action, it is preferable that at least a buffer spring 13 is provided between the third suction cup 113 and the base plate 12. By providing the buffer spring 13, a buffer can be provided when the drive assembly 20 is driven to contact the medicine box, further avoiding the situation where the medicine box is dented or even damaged due to hard contact.

[0032] It is conceivable that buffer springs 13 could also be configured for the first suction cup 111 and the second suction cup 112 to reduce the probability of the medicine box being deformed or even damaged when they come into contact with it.

[0033] In one embodiment, the adsorption assembly 10 further includes a connecting plate 14, to which the drive assembly 20 is connected, and the connecting plate 14 is connected to the base plate 12 via a telescopic rod 15. The telescopic rod 15 further improves the overall toughness of the adsorption assembly 10, further reducing the probability of the medicine box deforming or even being damaged.

[0034] In one embodiment, the driving component 20 includes a first guide rail 21 and a second guide rail 22 that are perpendicular to each other. The second guide rail 22 is supported on the first guide rail 21 and is movable on the first guide rail 21. The adsorption component 10 is supported on the second guide rail 22 and is movable on the second guide rail 22.

[0035] Preferably, the drive assembly 20 further includes a rotary motor 23 supported on the second guide rail 22, and the adsorption assembly 10 is connected to the rotary motor 23 and rotated by it.

[0036] Furthermore, the rotary motor 23 and the adsorption assembly 10 are connected by a connecting rod 24, which is detachably connected to both the rotary motor 23 and the adsorption assembly 10. Therefore, when applied to storage devices of different specifications, it can be adapted by replacing the connecting rod 24 with one of different lengths, thereby improving the flexibility and adaptability of the entire drug transfer mechanism 100.

[0037] Therefore, the drive assembly 20 can drive the adsorption assembly 10 to perform dual-axis motion and rotation. Of course, to meet the needs of the equipment, the drive assembly 20 can also be configured as a three-axis or higher drive configuration, and this embodiment is not limited thereto.

[0038] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
