Description

Technical Field

[0001] The utility model belongs to the technical field of reagent storage equipment, and particularly relates to a reagent batch automatic storage and retrieval device. Background Art

[0002] At present, reagent cabinets on the market generally use automatic storage and retrieval devices to realize automatic storage of reagents, thereby realizing intelligent management of reagents. However, the automatic storage and retrieval devices of existing reagent cabinets have the following problems: First, during the reagent storage process, it is necessary to manually place the reagents one by one on the automatic storage and retrieval device through the feed port. When multiple reagents need to be stored in batches, since the transportation mechanism of the automatic storage and retrieval device can only transport a limited number of reagents, the operator is often required to wait for a period of time before continuing to store, which seriously affects the reagent storage and retrieval efficiency.

[0003] Secondly, the automatic storage and retrieval devices of some reagent cabinets avoid the above-mentioned low efficiency problem by setting up multiple transportation mechanisms (such as reagent trays), but this increases the size of the automatic storage and retrieval device, resulting in a bloated reagent cabinet and a large space occupation. It also increases the corresponding operating power consumption and increases the reagent storage cost.

[0004] In addition, during the process of storing and retrieving reagents, existing automatic storage and retrieval devices often require mechanical claws to automatically rotate and adjust the storage position and direction of the reagents to ensure that the reagents are placed stably. However, the rotation of the mechanical claws and the adjustment of the reagent position and direction increase the operating power consumption while also increasing the corresponding storage and retrieval operation time, thereby reducing the efficiency of automatic storage and retrieval. This is especially true when used in the process of batch reagent storage, as operators are often required to wait for long time intervals, which seriously affects the efficient and intelligent management of reagents.

[0005] Therefore, it is necessary to design a reagent batch automatic storage and retrieval device that occupies a small space and has high storage and retrieval efficiency. Summary of the invention

[0006] In order to solve the above technical problems, the utility model proposes a reagent batch automatic storage and retrieval device, which has a compact structure and occupies a small space. It can automatically and synchronously perform batch storage and retrieval operations on multiple reagents, effectively improving the reagent storage and retrieval efficiency. There is no need to rotate or adjust the reagent position during the storage and retrieval process, thereby improving the reagent storage stability and reducing the required power consumption.

[0007] The technical solution of the utility model is:

[0008] The utility model provides a reagent batch automatic storage and retrieval device, comprising:

[0046] like Figure 3 As shown, the temporary storage unit 13 includes a temporary storage platform 132 and a plurality of temporary storage trays 131 evenly spaced apart and placed on the temporary storage platform 132 . The temporary storage platform 132 is fixedly disposed on the supporting platform 14 and arranged opposite to the depositing unit 11 .

At the same time, the empty storage tray 111 follows the rotating chain belt 113 to flip from the bottom to the top of the rotating chain belt 113. At this time, the drive motor 112 stops working, and the operator can continue to add storage reagents. At the same time, the positioning and conveying unit 21 cooperates with the clamping unit 22 to clamp the reagents in the fully loaded storage tray 111 one by one to the temporary storage seat 132. Repeat the above steps to complete the batch storage of reagents in the temporary storage tray 131 on the storage platform 132; reagent removal process: the reagent storage cabinet transports the reagents to be removed to the temporary storage tray 131 of the temporary storage platform 132 (usually transports the entire temporary storage tray 131), the capping motor 123 works to drive the removal box 121 to move to the rear end (close to the temporary storage platform 132), and the cover plate 122 moves to the front end (away from the temporary storage platform 132), and at the same time, the positioning and conveying unit 21 cooperates with the gripping unit 22 to clamp the remaining reagents in the tray and place them in the removal box 121, the capping motor 123 rotates in the opposite direction to drive the removal box 121 to move to the front end, and the cover plate 122 moves to the rear end, and the operator can take the reagents from the removal box 121 at the front position.

[0051] To sum up, the automatic reagent batch storage and retrieval device provided by the utility model has a compact structure and occupies a small space. It can automatically and synchronously perform batch storage and retrieval operations on multiple reagents, effectively improving the reagent storage and retrieval efficiency.
