[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Among them, the terms "first position" and "second position" are two different positions, and the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] like Figure 1 and Figure 2 As shown, the present embodiment provides an incubation transfer mechanism, which includes a scheduling disk 100, an incubation disk 200 and a transfer assembly 300, wherein a first scheduling station 110 is provided on the scheduling disk 100; an incubation station 210 is provided on the incubation disk 200, and the incubation disk 200 is coaxially arranged with the scheduling disk 100, and rotates relatively independently; the output end of the transfer assembly 300 can swing around a rotating shaft, and the axis of the rotating shaft is parallel to the axis of the incubation disk 200, and the first scheduling station 110 and the incubation station 210 are both located on the swinging path 310 of the output end of the transfer assembly 300.

[0034] The above arrangement can reduce the overall footprint of the scheduling tray 100 and the incubation tray 200, thereby reducing the footprint of the entire incubation transfer mechanism, which is conducive to adapting to a smaller working environment and helps to achieve miniaturization and compactness of the equipment.

[0035] When incubating, it is generally necessary to heat up the incubation tray 200. In order to reduce the heat dissipation, in some embodiments, the scheduling tray 100 is annular, the incubation tray 200 is disc-shaped, and the incubation tray 200 is located inside the scheduling tray 100. The above arrangement enables the incubation tray 200 to be surrounded by the scheduling tray 100, and the incubation tray 200 is located in the center, which helps to reduce the heat dissipation and is conducive to the accumulation of heat. Under the premise of constant temperature, the amount of heat required to be provided is reduced, thereby achieving energy conservation and emission reduction. Further, a thermal insulation layer can be provided around the outer periphery of the incubation tray 200, and the thermal insulation layer is located between the incubation tray 200 and the scheduling tray 100. Specifically, the thermal insulation layer can be a vacuum layer or a foam layer.

[0036] When in use, it is generally necessary to transfer the reaction cup to the scheduling disk 100 first, and then the scheduling of the scheduling disk 100 moves the reaction cup to each station to add samples and reagents. In order to facilitate the above-mentioned working method, specifically, the incubation transfer mechanism also includes a cup-dividing member 400, which is located on the peripheral side of the scheduling disk 100, and the cup-dividing member 400 is located on the swing path 310 of the output end of the transfer component 300. The transfer component 300 is used to transfer the reaction cup from the cup-dividing member 400 to the scheduling disk 100. The above-mentioned setting enables the incubation transfer mechanism to only need one transfer component 300, which can transfer the reaction cup between the first scheduling station 110 and the incubation station 210, and can also transfer the reaction cup between the cup-dividing member 400 and the first scheduling station 110, which helps to save the number of transfer components 300 and save costs.

[0037] If the reaction cup is unqualified, for example, it has cracks and other defects, and enters the incubation tray 200 during the test, it will cause errors in the final test results, thereby affecting the accuracy of the test. To avoid the above problems, in some embodiments, the incubation transfer mechanism also includes a waste cup part 430, which is located between the scheduling tray 100 and the cup-dividing part 400, and is located on the swing path 310 at the output end of the transfer assembly 300. The above arrangement allows the reaction cup to directly throw the unqualified reaction cup into the waste cup part 430 during the transfer between the cup-dividing part 400 and the first scheduling station 110, thereby avoiding errors in subsequent test results due to unqualified reaction cups and reducing waste caused by subsequent processes.

[0038] Whether the reaction cup is qualified or not needs to be tested to determine. In some embodiments, the cup-distributing member 400 has a cup-receiving position 410, a cup-discharging position 420 and a testing position. The rotation process of the cup-distributing member 400 can move the reaction cup located at the cup-receiving position 410 to the testing position and the cup-discharging position 420 in sequence. The cup-discharging position 420 is located on the swing path 310 at the output end of the transfer component 300. The reaction cup is marked as qualified or unqualified at the testing position. The transfer component 300 can move the qualified reaction cup from the cup-discharging position 420 to the first scheduling station 110, and can move the unqualified reaction cup to the waste cup member 430. The above-mentioned setting helps to complete the detection during the reaction cup transfer process, and can complete the discarding action through the same transfer component 300, thereby improving the detection efficiency and reducing the cost.

[0039] In order to allow the sample and the reagent to react fully, the sample and the reagent need to be mixed before the reaction. To this end, in some embodiments, the incubation transfer mechanism also includes a first mixing member 510, the scheduling disk 100 is also provided with a second scheduling station 120, and the second scheduling station 120 is located on the swing path 310 of the output end of the transfer component 300, the first mixing member 510 is located on the outside of the scheduling disk 100, and is located on the swing path 310 of the output end of the transfer component 300, and the transfer component 300 is used to transfer the reaction cup from the second scheduling station 120 to the first mixing member 510, and can transfer the reaction cup from the first mixing member 510 to the incubation station 210. The above-mentioned setting enables the same transfer component 300 to move the reaction cup loaded with the sample and the reagent from the second scheduling station 120 to the first mixing member 510 for mixing, and can transfer the reaction cup mixed with the sample and the reagent to the incubation station 210, further reducing the number of transfer components 300 and reducing costs.

[0040] In some embodiments, the first dispatching station 110 and the second dispatching station 120 are sequentially arranged at intervals around the axis of the dispatching disk 100. The dispatching disk 100 is provided with a filling station 130, and the filling station 130 is located between the first dispatching station 110 and the second dispatching station 120. The above arrangement allows the dispatching disk 100 to pass through the first dispatching station 110, the filling station 130 and the second dispatching station 120 in sequence during its rotation. Specifically, the scheduling disk 100 is provided with a plurality of scheduling installation parts, each of which can be placed with a reaction cup. During the rotation of the scheduling disk 100, each scheduling installation part passes through the first scheduling station 110, the filling station 130 and the second scheduling station 120 in sequence. When the scheduling installation part moves to the first scheduling station 110, the transfer component 300 moves the reaction cup from the cup separation part 400 to the scheduling installation part at the first scheduling station 110. When the reaction cup moves to the filling station 130, the filling component 131 can fill the sample and the reagent into the reaction cup. When the reaction cup moves to the second scheduling station 120, the transfer component 300 moves the reaction cup to the first mixing part 510.

[0041] Regarding the working method of the transfer component 300, in some embodiments, due to the rotation process of the scheduling disk 100, the scheduling installation component passes through the first scheduling station 110 and the second scheduling station 120 in sequence, so in specific operations, the output end of the transfer component 300 can be moved between the reaction cup and the scheduling disk 100, and the reaction cup is first moved to the scheduling installation component at the first scheduling station 110. When all the scheduling installation components of the scheduling disk 100 are placed with reaction cups, the output end of the transfer component 300 can be moved between the first mixing component 510 and the scheduling disk 100, and the reaction cups are moved one by one from the second scheduling station 120 to the first mixing component 510, and the reaction cups in which the sample and reagent are mixed are moved to the incubation station 210.

[0042] Considering that the mixing process of the sample and the reagent takes a long time, in order to reduce the time required for the entire mixing process, in some embodiments, the incubation transfer mechanism further includes a second mixing member 520, which is located outside the scheduling disk 100 and on the swing path 310 of the output end of the transfer assembly 300. The transfer assembly 300 is used to transfer the reaction cup from the second scheduling station 120 to the second mixing member 520, and can transfer the reaction cup from the second mixing member 520 to the incubation station 210. The above arrangement improves the mixing efficiency, and on the basis of moving the reaction cup from the second scheduling station 120 to the first mixing member 510 through the transfer assembly 300, the reaction cup can also be moved from the second scheduling station 120 to the second mixing member 520, thereby reducing the number of transfer assemblies 300 and reducing costs.

[0043] Among them, the incubation tray 200 is provided with a plurality of incubation positions, and during the rotation of the incubation tray 200, each incubation position can pass through the incubation station 210. The above arrangement improves the incubation efficiency, and completes the testing of multiple samples in the same batch, which helps to ensure the consistency and reliability of the results. The plurality of incubation positions of the incubation tray 200 are arranged in a ring shape and have at least two layers. Specifically, the plurality of incubation positions are arranged in a ring shape and have three layers.

[0044] The transfer assembly 300 includes a first arm, a second arm and a gripper, wherein one end of the first arm is rotatably arranged around a rotation axis, the second arm is slidably arranged at the other end of the first arm along a lifting axis, and the gripper is arranged at the lower end of the second arm. The rotation axis and the lifting axis are arranged in parallel. With the structural arrangement of the transfer assembly 300, the gripper can be swung and lifted up and down, so that the reaction cup can be transferred between various workstations. Specifically, the specific driving method of the first arm, the second arm and the gripper can be completed by conventional means in the field, which is not the focus of this application, so it is not described in detail here.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
