[0036] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] The cup unscrambling module and the sample analyzer according to the present invention are described below with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a cup sorting module is provided, comprising:

[0039] A reaction cup loading bin 10 is used to hold a plurality of reaction cups 70;

[0040] The cup unscrambling drum 20 has a plurality of partitions 21 spaced apart on its inner circumferential wall. The plurality of partitions 21 and the inner circumferential wall of the cup unscrambling drum 20 are arranged obliquely. A guide channel 22 is formed between any two adjacent partitions 21. The feed end of the guide channel 22 is connected to the discharge end of the reaction cup charging bin 10.

[0041] The baffle plate 25 is located at a side of the cup arranging drum 20 away from the reaction cup loading bin 10, and a cup outlet 23 for the reaction cup 70 to be discharged is formed on the baffle plate 25;

[0042] The rotary drive assembly 61 is used to drive the cup unscrambling drum 20 to rotate, so as to drive the discharge end of each guide channel 22 to rotate in sequence to a position communicating with the cup outlet 23; and

[0043] The cup pushing mechanism includes a conveying assembly and a cup pushing assembly 50 . The conveying assembly forms a cup drop opening 44 and a conveying channel 30 connected to the cup outlet 23 . The cup pushing assembly 50 is used to push the reaction cups 70 in the conveying channel 30 to the cup drop opening 44 in sequence.

[0044] When the cups are sorted, multiple cups 70 in the cup loading bin 10 enter the cup sorting drum 20, and the rotating drive assembly 61 drives the cup sorting drum 20 to rotate, so that under the centrifugal force of the rotation, each guide channel 22 will flow into the cup 70, and as the rotation proceeds, when any one of the guide channels 22 is aligned with the cup outlet 23, the cups 70 in the guide channel 22 will be thrown out from the cup outlet 23 and enter the conveying channel 30; under the action of gravity, the cups 70 fall vertically, and then the cup pusher assembly 50 pushes the cups 70 in the conveying channel 30 to the cup drop port 44 and drops them into the reaction tray to start the next process. The present application improves the inner circumferential wall structure of the cup sorting drum 20, and cooperates with the cup drop and cup pusher functions of the conveying channel 30 and the cup pusher assembly 50, so that under the combined action of the rotating drive assembly 61 and gravity, the messy cups 70 can fall vertically into the conveying channel 30 in sequence without cup jamming.

[0045] In an embodiment of the present invention, a plurality of guide channels 22 are sequentially arranged along the circumference of the cup unscrambling drum 20, and the two partition sections 21 of the same guide channel 22 are arranged relatively inclined with the inner peripheral wall of the cup unscrambling drum 20. That is to say, in the same guide channel 22, the extension lines of the side walls of the opposite surfaces of the two partition sections 21 and the extension lines of the inner peripheral wall of the cup unscrambling drum 20 are both intersected toward the cup outlet 23. By improving the angle of the inner peripheral wall of the guide channel 22, the inner side walls of the two partition sections 21 can prevent the reaction cups 70 in the guide channel 22 from flying out, so that the reaction cups 70 in each guide channel 22 are always kept inside until the discharge end of the guide channel 22 is connected to the cup outlet 23, and then the reaction cups 70 in the guide channel 22 connected to the cup outlet 23 are driven to be thrown out from the cup outlet 23.

[0046] In an embodiment of the present invention, the conveying channel 30 includes a vertical channel 31, a V-groove channel 32 and a cup dropping channel 33 which are connected in sequence from top to bottom. The large end of the V-groove channel 32 opens toward the vertical channel 31, the small end of the V-groove channel 32 is connected to the cup dropping channel 33, and one end of the cup dropping channel 33 is connected to the cup dropping mouth 44.

[0047] The cup drop channel 33 is a long guide hole that runs through from top to bottom. The upper end of the cup drop channel 33 is connected to the V-groove channel 32, and the lower end is open, so that the reaction cup 70 that falls into the cup drop channel 33 can fall vertically into the cup drop channel 33 under the action of gravity, and the bottom of the reaction cup 70 can extend from the bottom of the cup drop channel 33. Since a circle of clamping rings are provided on the outer peripheral wall of the reaction cup 70, the clamping rings can be clamped on the top of the cup drop channel 33 during the falling process of the reaction cup 70, so as to prevent the entire reaction cup 70 from sliding down from the bottom of the cup drop channel 33. In addition, the cup drop channel 33 is extended in the front-to-back direction, so that the dropped reaction cup 70 can move toward the cup drop port 44 under the push of the cup pusher assembly 50, and the multiple reaction cups 70 that have not fallen out of the cup drop port 44 are arranged in sequence front to back along the extension direction of the cup drop channel 33 to prevent the reaction cup 70 from being horizontally placed, thereby ensuring that each reaction cup 70 can pass through the cup drop port 44 in sequence, thereby avoiding cup jamming or confusion.

[0048] In the embodiment of the present invention, the cup unscrambling module further includes a baffle 25, which is closed on the side of the cup unscrambling drum 20 away from the reaction cup loading bin 10, and the cup outlet 23 is opened on the baffle 25, and the cup outlet 23 is provided with an inclined guide plate 24 extending into the vertical channel 31. Preferably, the inclined angle of the inclined guide plate 24 is set to 45°. Through this design, the reaction cups 70 sliding out of the cup outlet 23 can fall into the vertical channel 31 in sequence at an inclined angle of 45° under the inclined guiding effect of the inclined guide plate 24.

[0049] In an embodiment of the present invention, the conveying assembly includes a conveying guide block 41 and two inclined plates 42; a cup drop channel 33 for sequentially arranging reaction cups 70 is provided inside the conveying guide block 41 along a first direction, a cup drop bucket 43 connected to the cup drop channel 33 is provided below the end of the conveying guide block 41, and a cup drop opening 44 is provided at the bottom of the cup drop bucket 43;

[0050] Two inclined plates 42 are mounted on the conveying guide block 41 and are symmetrically arranged on both sides of the top of the cup dropping channel 33 , and a V-shaped groove channel 32 communicating with the cup dropping channel 33 is formed between the two inclined plates 42 .

[0051] The reaction cup 70 that falls from the cup outlet 23 into the vertical channel 31 at an inclined angle of 45° gradually changes into a vertical falling motion under the action of gravity; and in order to enable the reaction cup 70 to maintain a vertical posture and fall into the cup falling channel 33, a V-groove channel 32 with a guiding function on both sides is provided between the cup falling channel 33 and the vertical channel 31, thereby ensuring that all reaction cups 70 can fall vertically.

[0052] In order to prevent the cuvette 70 in the cup drop channel 33 from falling, and the cuvette 70 pushed into the cup drop bucket 43 needs to fall from the cup drop opening 44 at the bottom, the inner diameter of the cup drop bucket 43 needs to be designed to be larger than the width of the cup drop channel 33, so that the cuvette 70 pushed from the cup drop channel 33 can smoothly fall from the cup drop opening 44 of the cup drop bucket 43. In addition, in order to ensure the orderly cup drop, the inner diameter of the cup drop bucket 43 is set to a size that can only accommodate one cuvette 70, so that multiple cuvettes 70 can fall in sequence and smoothly, and there will be no confusion of multiple cuvettes 70 falling at the same time.

[0053] like Figure 3 As shown, the cup pusher assembly 50 includes a pusher 51, a guide rail 52, a second linear drive member 54 and a first linear drive member 53; the guide rail 52 is installed on the outer wall of the conveying guide block 41 along the first direction; the second linear drive member 54 is used to drive the pusher 51 to approach or move away from the reaction cup 70 in the cup drop channel 33 along the second direction, and the first direction is perpendicular to the second direction; the first linear drive member 53 is installed on the guide rail 52 and is used to drive the second linear drive member 54 to move linearly along the first direction.

[0054] The first linear drive member 53 and the second linear drive member 54 both adopt a conventional linear drive structure of a drive motor and a rotating screw. Figure 3 The front-to-back direction in the second direction is Figure 3A slider is spirally sleeved on the rotating screw of the first linear drive member 53, one side of the slider is in sliding contact with the guide rail 52, and the other side of the slider is connected to the second linear drive member 54. When the rotating screw of the first linear drive member 53 rotates, it can drive the slider to slide along the guide rail 52.

[0055] When the cup pushing action is performed, the second linear driving member 54 drives the pushing member 51 to move to the left to contact the reaction cup 70, and then the first linear driving member 53 drives the second linear driving member 54 to move in the front-to-back direction to push the reaction cup 70 toward the cup dropping opening 44. When the reaction cup 70 reaches the cup dropping opening 44, the cup is dropped. In this reciprocating manner, the multiple reaction cups 70 in the cup dropping channel 33 are dropped in sequence to prevent the cup from getting stuck during the cup sorting process.

[0056] In the embodiment of the present invention, the conveying assembly further includes a fixed base 45, which is located on the side of the conveying guide block 41 away from the guide rail 52, and a vertical channel 31 is formed between the fixed base 45 and the baffle 25. The setting of the fixed base 45 can play a role in fixing the entire cup pushing assembly 50, preventing the movement of the entire cup pushing assembly 50 from affecting the experimental process during the cup pushing process.

[0057] In an embodiment of the present invention, the cup sorting module further includes a judgment element, which is a judgment optical coupler 60, and the judgment optical coupler 60 is arranged near the cup drop port 44 and is used to judge whether there is a reaction cup 70 dropped at the cup drop port 44. The cup sorting module also includes a control unit electrically connected to the judgment optical coupler 60. When the judgment optical coupler 60 identifies that there is a reaction cup 70 waiting to drop at the cup drop port 44, the control unit controls the cup pusher assembly 50 to stop the cup push action for the next reaction cup 70; when the judgment optical coupler 60 identifies that there is no reaction cup 70 at the cup drop port 44, the control unit controls the cup pusher assembly 50 to push the next reaction cup 70 to the cup drop port 44 to wait for it to drop. This method allows the reaction cup 70 to drop efficiently and smoothly from the cup drop port 44 without causing disorder.

[0058] In the embodiment of the present invention, the rotary drive assembly 61 includes a large synchronous wheel 62, a small synchronous wheel 63, a synchronous belt 64 wound around the large synchronous wheel 62 and the small synchronous wheel 63, and a rotary drive member 65 coaxially connected to the small synchronous wheel 63. The large synchronous wheel 62 is installed on the side of the cup unscrambling drum 20 facing the reaction cup loading bin 10. The rotary drive member 65 is preferably a servo motor; the servo motor rotates to drive the small synchronous wheel 63 to rotate, thereby driving the synchronous rotation of the large synchronous wheel 62; since the large synchronous wheel 62 is installed on the outer periphery of the cup unscrambling drum 20, when the large synchronous wheel 62 rotates, it can drive the entire cup unscrambling drum 20 to rotate radially at the same time.

[0059] In an embodiment of the present invention, a sample analyzer is also provided, comprising the cup unscrambling module as described above.
