Description

Technical Field

[0001] This utility model relates to the field of in vitro diagnostic equipment technology, and in particular to a large-capacity incubation device with dual grippers. Background Technology

[0002] Sample analysis instruments are important in vitro diagnostic devices. In use, the sample and reagents are injected into a reaction vessel, mixed, and then the vessel is grasped by a gripper and placed in an incubation device that simulates the body's temperature environment. The solution in the reaction vessel undergoes an effective reaction at a preset temperature for a certain period. Afterward, the gripper removes the reaction vessel for further processing. Existing incubation equipment suffers from problems such as low sample transfer efficiency, poor incubation and heat preservation, and spillage from the reaction vessel. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a large-capacity incubation device with dual grippers, specifically employing the following technical solution:

[0004] The large-capacity incubation device with dual grippers described in this utility model includes a rotating incubation tray. A fixed insulating shell is provided on the outer side of the incubation tray. The insulating shell is a concentric circular structure aligned with the incubation tray. The top of the insulating shell has a first retrieval port located in a first quadrant and a second retrieval port located in a third quadrant. The first and second retrieval ports are located in odd-numbered quadrants or even-numbered quadrants, respectively. The central axes of both the first and second retrieval ports are parallel to the Y-axis. The central axis of the first and second pick-up / placement ports are equidistant from the Y-axis. The Y-axis length of the first pick-up / placement port is equal to that of the second pick-up / placement port, and the first and second pick-up / placement ports are equidistant from the X-axis. An upward-opening reaction cup receiving groove is provided on the incubation tray. The reaction cup receiving grooves are uniformly arranged along the circumference of the incubation tray. The angle between the center line of the major axis of each reaction cup receiving groove and the radius of the center of the reaction cup receiving groove is α. When the reaction cup receiving groove passes through the first or second pick-up / placement port to pick up or place the reaction cup, its major axis center line is parallel to the Y-axis.

[0005] The reaction cup receiving groove is arranged in a concentric circle structure with multiple rings. The α angle of the reaction cup receiving grooves on the same circumference is equal, and the α angle of the inner ring reaction cup receiving groove is larger than the α angle of the adjacent outer ring reaction cup receiving groove.

[0006] The Y-axis length of the first and second pick-up ports is equivalent to the length of one or more reaction cup receiving tanks from the inside to the outside.

[0007] The inlet of the reaction cup is surrounded by anti-splash foam, which is fixed by a cover plate located above it.

[0008] A heat-conducting clamp is provided on the bottom surface of the incubation tray, and a heating plate and an insulating clamp are arranged in sequence below the heat-conducting clamp.

[0009] The bottom center of the incubation plate is connected to the rotating shaft of the drive mechanism. The rotating shaft is a hollow structure, and the bottom of the rotating shaft is connected to a fixed shaft through a bearing. A conductive slip ring for supplying power to the heating plate is provided above the fixed shaft.

[0010] The top, bottom, and inner surfaces of the insulation shell are all provided with insulation cotton, which is spaced apart from the incubation tray.

[0011] The reaction cups placed in the reaction cup receiving slot are round, square, or irregularly shaped.

[0012] The dual-gripper, high-capacity incubation device provided by this utility model has an ingenious structure, low cost, and is easy to use. The same volume of incubation tray can hold more reaction cups, and the carefully designed reaction cup receiving groove allows the same reaction cup to be grasped sequentially by two sets of grippers at different positions, improving grasping efficiency by at least 100%. The incubation tray features an improved heating module design, ensuring a consistently balanced temperature within the tray and reducing temperature bias. Furthermore, comprehensive insulation measures are employed around the reaction cup receiving groove, further enhancing incubation efficiency. An anti-splash structure is also incorporated at the inlet of the reaction cup receiving groove, eliminating the impact of splashing from the reaction cups and improving the stability of the test results.

[0018] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0019] like Figure 1-5 As shown, the large-capacity incubation device for the dual gripper described in this utility model includes a base 1, four support columns 2 on the base, a fixed incubation shell 3 on the support columns 2, and an incubation tray 5 connected to a rotary drive mechanism 4 inside the incubation shell 3.

[0020] The aforementioned incubation dish 5 has a disc-shaped structure with multiple upward-opening reaction cup receiving slots 6. The reaction cup receiving slots 6 are evenly distributed around the circumference of the incubation dish 5, forming a single-ring structure (see...). Figure 3 ) or concentric circle structures with multiple rings (see Figure 2 Furthermore, the angle between the centerline of the major axis of each reaction cup receiving slot 6 and the radius at the center of that reaction cup receiving slot 6 is α. The α angles of the reaction cup receiving slots on the same circumference are equal, and the α angle of the inner ring of reaction cup receiving slots is larger than that of the adjacent outer ring of reaction cup receiving slots. This arrangement of the reaction cup receiving slots 6 maximizes the placement and removal of reaction cups, while also optimizing the arrangement of the number of reaction cups to be placed and removed on the incubation tray 5.

[0021] The heat-insulating shell 3 is located outside the incubation tray 5, and it is a concentric circular structure with the incubation tray 5. The top of the heat-insulating shell 3 has a first access port 7 in the first quadrant and a second access port 8 in the third quadrant (of course, the first access port 7 can also be located in the second quadrant, in which case the second access port 8 is located in the fourth quadrant). A first gripper is correspondingly provided above the first access port 7. Figure 3 The straight line L1 is the moving path of the first gripper), and a second gripper is correspondingly set above the second pick-up / placement port 8. Figure 3 (The central straight line L2 represents the movement path of the second gripper). The central axes of the first pick-up / placement port 7 and the second pick-up / placement port 8 are both parallel to the Y-axis, and are equidistant from the Y-axis. The Y-axis lengths of the first pick-up / placement port 7 and the second pick-up / placement port 8 are equal, and are equidistant from the X-axis. When the reaction cup receiving slot 6 passes through the first pick-up / placement port 7 and the second pick-up / placement port 8 to pick up or place the reaction cup, the center line of the major axis of the reaction cup receiving slot 6 remains parallel to the Y-axis. This allows for the "grabbing of the same reaction cup using different grippers," thereby improving the efficiency of reaction cup handling. For example, the reaction cup is placed into the reaction cup receiving slot 6 through the first pick-up / placement port 7 using the first gripper. After the incubation tray 5 rotates 180°, the reaction cup reaches the second pick-up / placement port 8, where it is removed by the second gripper. Typically, the Y-axis length of the first loading / unloading port 7 and the second loading / unloading port 8 is approximately equal to the length of one or more reaction cup receiving tanks from the inside out, meaning that one or more ( Figure 2The system includes six reaction cup receiving slots (6 in total), allowing the gripper to flexibly grasp reaction cups at different positions. It should be noted that the reaction cups placed in the aforementioned reaction cup receiving slots 6 can be round, square, or irregularly shaped.

[0022] To heat the liquid in the reaction vessel, a heat-conducting clamping plate 9 is installed on the bottom surface of the incubation tray 5, and a heating plate 10 and an insulating clamping plate 11 are sequentially installed below the heat-conducting clamping plate 9. The heating plate 10 is powered by a conductive slip ring 12. The conductive slip ring 12 is located inside the hollow rotating shaft 13 of the drive mechanism. Specifically, the drive mechanism includes a driving wheel driven by a rotary motor, which is connected to a driven wheel via a synchronous belt. The hollow rotating shaft 13 is fixedly mounted at the center of the driven wheel, and the bottom of the hollow rotating shaft 13 is connected to a fixed shaft 15 mounted on the base plate 1 via a bearing 14. The conductive slip ring 12 is installed above the fixed shaft 15. In addition, a temperature sensor is installed between the incubation tray 5 and the heat-conducting clamping plate 9, and the temperature signal of the temperature sensor is also transmitted through the conductive slip ring 12. To prevent heat loss, in addition to the first and second access ports 7 and 8, insulation cotton 16 is provided on the top, bottom, and inner surfaces of the insulation shell 3. Specifically, this includes top insulation cotton, bottom insulation cotton, inner ring insulation cotton, and outer ring insulation cotton (see...). Figure 4 The aforementioned insulating cotton 16 is spaced apart from the incubation tray 5. Furthermore, insulating cotton can also be placed between adjacent reaction cup receiving tanks 6 to minimize heat loss from the incubation tray 5 and maintain the temperature of the liquid inside the reaction cup.

[0023] When the gripper places the reaction cup into the reaction cup receiving slot 6, a hard contact can easily occur, causing liquid splashing and leading to abnormal test results. Therefore, anti-splash foam 17 is installed around the inlet of each reaction cup receiving slot 6. The anti-splash foam 17 is fixed by a cover plate 18 located above it, or the anti-splash foam 17 has adhesive backing and is directly attached to the incubation tray 5 around the inlet of the reaction cup receiving slot 6. When the reaction cup is placed downwards, the reaction cup comes into contact with the anti-splash foam 17 around the reaction cup receiving slot 6. At this time, due to the damping and buffering effect of the anti-splash foam 17, the reaction cup can fall slowly, thereby eliminating the adverse effects of reaction liquid splashing from the reaction cup and improving the stability of the instrument's test results.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
