[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0020] Reference Figure 1-2 The cuvette pick-and-place device in the embodiment of the present invention comprises a base 10, a clamping part 20 and an elastic member. The base 10 is provided with a mounting groove 11 for mounting a cuvette 40. The first end of the clamping part 20 is hinged on the base 10. The second end of the clamping part 20 can move away from or approach the mounting groove 11 during the rotation around the hinge. The elastic member connects the base 10 and the clamping part 20. The elastic member is used to apply an elastic force to the clamping part 20 to move closer to the mounting groove 11. The clamping part 20 is rotated to move the second end of the clamping part 20 away from the mounting groove 11, so that the cuvette 40 can be loaded into the mounting groove 11. Then, the clamping part 20 is rotated and approaches the mounting groove 11 under the action of the elastic force of the elastic member, so that the cuvette 40 is clamped in the mounting groove 11 to prevent the cuvette 40 from falling out of the present invention. The elastic member can ensure that the cuvette 40 is always stably clamped in the mounting groove 11 without consuming energy.

[0021] It can be understood that the width of the mounting groove 11 is greater than the diameter of the cup body of the reaction cup 40 and less than the diameter of the cup ear of the reaction cup 40, so that the reaction cup 40 can be prevented from falling off while accommodating the cup body of the reaction cup 40. The mounting groove 11 has a side opening, and the reaction cup 40 enters and exits the mounting groove 11 through the side opening. As one optional embodiment, the second end of the clamping part 20 is located on one side of the side opening of the mounting groove 11, and the elastic member applies a horizontal elastic force to the clamping part 20, thereby pressing the reaction cup 40 in the mounting groove 11 to prevent the reaction cup 40 from falling out of the side opening. As another optional embodiment, in this embodiment, the second end of the clamping part 20 is located above the mounting groove 11, and the clamping part 20 presses the cup ear of the reaction cup 40 against the top surface of the mounting groove 11 under the action of the elastic member. Since the clamping part 20 does not move at the side opening, it usually does not block the reaction cup 40 from entering and exiting the mounting groove 11 when taking and placing the reaction cup 40, and the required operating space is smaller.

[0022] Furthermore, a clamping member 21 is provided at the second end of the clamping portion 20, and the width of the clamping member 21 gradually decreases from top to bottom. In the present application, the width of the clamping member 21 refers to the maximum value of the distance between any two points of the clamping member 21 on the horizontal cross section. In the present embodiment, the clamping member 21 is in the shape of a strip, and the clamping member 21 is bent to form a V-shape with an opening upward, so as to ensure that when the second end of the clamping portion 20 approaches the mounting groove 11, the clamping member 21 can at least partially pass through the mounting groove 11, thereby preventing the reaction cup 40 from falling out of the side opening.

[0023] It can be understood that the clamping part 20 is hinged on the base 10 through the rotating shaft 31. As one of the optional embodiments, the elastic member is a telescopic spring, and the two ends of the telescopic spring are respectively connected to the base 10 and the clamping part 20. When the clamping part 20 rotates to move away from the mounting groove 11, the telescopic spring is stretched, and when the clamping part 20 is reset, the telescopic spring contracts and returns to the initial state. Since the connection between the telescopic spring and the clamping part 20 is not a pure linear motion when the clamping part 20 rotates, the telescopic spring will deform during the telescopic process. As another optional embodiment, in this embodiment, the elastic member is a torsion spring 30, one end of the torsion spring 30 is connected to the base 10, and the other end of the torsion spring 30 is connected to the clamping part 20. Further, the torsion spring 30 is sleeved on the rotating shaft 31, so the position of the torsion spring 30 will not be greatly offset, and the structure is not easy to deform.

[0024] A top column 22 is provided on the bottom surface of the clamping part 20, and a base opening is provided on the base 10, and the base opening can accommodate the top column 22 to pass through. In the initial state, the top column 22 of the clamping part 20 passes through the base opening under the action of the force of the elastic member. The base 10 drives the clamping part 20 to descend together. When the bottom end of the top column 22 contacts other equipment or the platform surface, the top column 22 is lifted up, thereby driving the clamping part 20 to overcome the elastic force of the elastic member, and the clamping part 21 is away from the mounting groove 11 so that the reaction cup 40 can be loaded or removed. Correspondingly, when the base 10 is lifted, the top column 22 approaches the mounting groove 11 again under the action of the elastic member, and the clamping part 21 presses the reaction cup 40 in the mounting groove 11.

[0025] In some embodiments, the reaction cup picking and placing device also includes a robotic arm, which includes a gripping part, a lifting power mechanism and a rotating power mechanism. The base 10 is installed on the gripping part, and the gripping part is connected to the lifting power mechanism. The lifting power mechanism is used to drive the gripping part to lift and lower; the gripping part is connected to the rotating power mechanism, and the rotating power mechanism is used to drive the gripping part to rotate on a horizontal plane.

[0026] The working steps of the present invention are as follows:

[0027] The robot arm first drives the base 10 to rotate to the cuvette 40 placement area, and then drives the base 10 to descend. After descending to a fixed height, the bottom end of the top column 22 contacts the instrument platform to lift the clamping part 20. The robot arm drives the base 10 to rotate to the cuvette 40 so that the cuvette 40 can be accommodated in the mounting groove 11 and fit the mounting groove 11. Then the robot arm drives the base 10 to rise, and the clamping part 20 fixes the cuvette 40 in the mounting groove 11 under the action of the torsion spring 30. Finally, the robot arm drives the base 10 to rotate to the corresponding reactor placement area, descends again to release the clamping part 20 from the cuvette 40, and then rotates to make the mounting groove 11 leave the cuvette 40, and the placement of the cuvette 40 is completed.

[0028] The above is a specific description of the preferred implementation mode of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
