[0016] The embodiments of the utility model will be described in detail below with reference to the drawings, and the embodiments are implemented on the premise of the technical scheme of the utility model, and detailed implementation modes and specific operation processes are given, but the protection scope of the utility model is not limited to the following embodiments.

[0017] It should be noted that, in the description of the utility model, the relationship terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations.

[0018] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected" that may appear should be understood broadly, for example, can be fixedly connected, or integrally connected, can be mechanically connected, or electrically connected, can be directly connected, or indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0019] As shown in figures Figures 1-2 And 5, the reaction cup hovering placement device of the utility model, including the mechanical gripper 1 for grabbing the reaction cup 6 and the driving disc 2 driven by the power source and rotated, the driving disc 2 has a plurality of limit clamping grooves 3 uniformly arranged in the circumferential direction, the driving disc 2 is provided with a protective cover 4, the protective cover 4 is provided with a placing opening 5, the limit clamping grooves 3 can pass through the placing opening 5 in turn by rotating the driving disc 2, and the continuous placement of the reaction cup 6 is realized, the mechanical gripper 1 has a vertical mounting piece (i.e. mounting plate 1.1) and a pair of opening and closing clamping pieces 1.2 (for clamping the reaction cup), the clamping piece 1.2 of the mechanical gripper 1 can realize the clamping of the reaction cup 6 when closed.

[0020] The reaction cup hovering placement device of the utility model further includes a pressing piece 7 for pressing the reaction cup 6 downwards, the pressing piece 7 has a fixed part (i.e. fixed sheet 7.1) fixed on the lower part of the mounting plate 1.1 and a horizontal pressing part (i.e. pressing sheet 7.2), the pressing sheet 7.2 extends to the between the two clamping pieces 1.2 below the mounting plate 1.1, and the width of the clamping end of the limit clamping groove 3 is slightly smaller than the diameter of the lower part of the reaction cup 6.

[0021] In operation, the mechanical gripper 1 carries the reaction cup 6 to move to the placement opening 5 directly below and vertically opposite to one of the limiting card slots 3. The mechanical gripper 1 carries the reaction cup 6 to drop to a set height, so that the bottom of the reaction cup 6 is suspended at the clamping end of the limiting card slot 3; the clamping part 1.2 of the mechanical gripper 1 is opened to release the reaction cup 6 (at this time, the clamping part 1.2 has been separated from the reaction cup 6), and the mechanical gripper 1 continues to drop, in the process, the pressing piece 7.2 can press the reaction cup 6 into place by pressing the top of the reaction cup 6, thereby avoiding liquid splashing during placement, reducing the influence of liquid on the gripper and other instrument components, prolonging the maintenance cycle, and reducing maintenance costs; after the mechanical gripper 1 drops into place, it is raised to a preset height for grabbing another reaction cup 6, realizing continuous suspension placement of the reaction cup 6; since the width of the limiting card slot 3 is slightly smaller than the diameter of the reaction cup 6, when the reaction cup 6 is pressed into the limiting card slot 3, the limiting card slot 3 can provide a certain clamping force to avoid the situation that the mechanical gripper 1 is electrostatic or splashes liquid to stick to the cup, further ensuring that the reaction cup 6 is placed in place.

[0022] In combination with Figure 1 and Figure 4 It can be seen that the limiting card slots 3 are uniformly spaced along the circumferential direction of the driving disc 2, and the limiting card slots 3 are radially arranged. The inner end of the limiting card slot 3 is a clamping end, which has an opening 3.1. The slot wall near the opening 3.1 is an elastic movable clamping head 3.2 (preferably made of POM material). The driving disc 2 is provided with a movable slot 3.3 corresponding to each movable clamping head 3.2, and the movable slot 3.3 is arranged on the outer side of the movable clamping head 3.2. The movable slot 3.3 is in communication with the opening 3.1.

[0023] In the utility model, the movable clamping head 3.2 has a certain elasticity and a movable slot 3.3, and the movable slot 3.3 provides a certain space for the movable clamping head 3.2, so that the movable clamping head 3.2 opens outward at a certain angle when it is pressed by the reaction cup 6, thereby smoothly inserting the reaction cup 6 into the limiting card slot 3, clamping the reaction cup 6, avoiding the situation that the mechanical gripper sticks to the cup due to static electricity or splashing liquid during the rising and resetting process, and further avoiding the situation that the reaction cup is not placed in place due to sticking to the cup.

[0024] In one preferred embodiment of the utility model, in combination with Figure 4 It can be seen that the inner side of the movable clamping head 3.2 is a clamping protrusion 3.4 protruding in the opposite direction, which has a guiding effect, smoothly inserts the reaction cup 6 into the limiting card slot 3, and can also ensure the clamping force on the reaction cup 6, so that the reaction cup 6 is clamped in the limiting card slot 3.

[0025] In actual installation, since the clamping part 1.2 has a large installation space, the fixing piece 7.1 is preferably vertically arranged, which is fixed on one side of the mounting plate 1.1 by screws, facilitating installation; in combination withFigures 2-3 It can be known that the pressing piece 7.2 is fixed together by the connecting piece 7.3 and the fixing piece 7.1 in the L-shaped structure, the pressing piece 7.2 passes from the bottom of the mounting plate 1.1 and extends to the central position between the two clamping pieces 1.2, ensures that the pressing piece 7.2 is located directly above the reaction cup 6, makes the reaction cup 6 balanced in the placement process, avoids the reaction cup 6 from tilting due to uneven force, further avoids the liquid in the reaction cup 6 from splashing on the mechanical gripper 1 or other parts of the instrument, and prolongs the maintenance period. When working, since the pressing piece 7.2 is close to the reaction cup 6, when the mechanical gripper 1 releases the reaction cup 6 and continues to descend, the pressing piece 7.2 presses the reaction cup 6 to continue to descend, and the specific process is shown in Figure 1 .

[0026] In another embodiment of the present application, the fixing piece 7.1 can also be arranged horizontally and fixed to the bottom of the mounting plate 1.1, and the pressing piece 7.2 is located between the two clamping pieces 1.2 by the connecting piece 7.3.
