Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological detection technology, and in particular to a reagent card carrier device. Background Technology
[0002] Among existing devices for reagent card transfer, one type employs a large three-axis robotic arm as the main drive mechanism, using an end effector to grip and transfer the reagent cards. However, this type of structure suffers from two significant drawbacks in practical applications:
[0003] First, it occupies too much space and has poor integration compatibility. The large three-axis robotic arm structure itself has a large axial dimension and overall volume, which leads to significant installation space encroachment problems in application scenarios that need to be integrated with other equipment. This not only increases the difficulty of system integration, but also limits the deployment flexibility of the device in compact or space-constrained environments.
[0004] Secondly, the delivery method can easily lead to abnormal reagent card conditions. The design, which relies on the transport claw to directly deliver the reagent card, makes it difficult to ensure that the reagent card maintains the preset stable posture and force distribution throughout the transportation process. Specifically, factors such as improper selection of the contact point between the transport claw and the reagent card, uneven control of the lifting force, or vibration in the transportation path may cause problems such as the reagent card tilting, slipping, or falling off, thereby reducing the reliability of the transportation process and the safety of the reagent card. Summary of the Invention
[0005] The technical problem this invention aims to solve is to overcome the aforementioned deficiencies of the prior art and provide a reagent card transport device. This device, by employing a more compact layout of a card pushing mechanism and a reagent card transfer mechanism, significantly reduces its space occupation and overall volume, lowers system integration difficulty, enhances deployment flexibility in compact equipment and space-constrained environments, and expands the range of application scenarios. Furthermore, the use of the card pushing mechanism and reagent card transfer mechanism ensures the stability of the reagent cards during transport, effectively suppressing tilting, slippage, or detachment of the reagent cards caused by improper contact, uneven force, or path vibration, thus significantly improving transport reliability.

[0032] In some embodiments, a reagent card carrying device includes a card pushing mechanism 100 and a reagent card transfer mechanism 200;
[0033] The card pushing mechanism 100 includes a first card pushing component, which includes a first motor 102, a first transmission component connected to the first motor 102, and a first pusher 111 connected to the first transmission component. The first motor 102 drives the first transmission component so that the first pusher 111 pushes the reagent card 300 to the reagent card transfer mechanism 200.

This simplifies system integration, enhances deployment flexibility in compact equipment and space-constrained environments, and expands the range of applicable scenarios. Furthermore, it ensures reagent card stability during transport, effectively suppressing tilting, slippage, or detachment caused by improper contact, uneven force, or path vibration, thus significantly improving transport reliability.
