[0038] 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.

[0039] The material sorting module and the sample analyzer according to the present invention are described below with reference to the accompanying drawings. The material sorting module of the present application is used for sorting reaction cups 70 , so the technical solution of the present application is explained below using the reaction cup 70 as an example of the material.

[0040] like Figure 1As shown, in an embodiment of the present invention, a material sorting module is provided, including a loading bin 10, a receiving mechanism 20 and a pushing mechanism; a discharge port 11 is provided at the bottom of the loading bin 10; the receiving mechanism 20 is installed below the discharge port 11, and the receiving mechanism 20 includes a rotating shaft 21 and a driving assembly 80, and the rotating shaft 21 is provided with a plurality of receiving grooves 22 for receiving the reaction cups 70 flowing out of the discharge port 11 at intervals along the circumferential direction, and the driving assembly 80 is used to drive the rotating shaft 21 to rotate, so as to drive the opening of each receiving groove 22 to rotate in sequence to a position connected with the discharge port 11; the pushing mechanism includes a conveying assembly and a pushing assembly 50, the conveying assembly forms a drop port 44 and a conveying channel 30, the rotating shaft 21 is arranged corresponding to the upper end opening of the conveying channel 30, and the pushing assembly 50 is used to push the reaction cups 70 in the conveying channel 30 to the drop port 44 in sequence.

[0041] Among them, the opening of each receiving groove 22 is set to the outside. As the driving component 80 drives the rotation shaft 21 to rotate, when one of the receiving grooves 22 rotates to the position of the discharge port 11, it can receive the reaction cup 70 flowing out of the discharge port 11. As the rotation shaft 21 continues to rotate, the notch of the receiving groove 22 containing the reaction cup 70 rotates to the position of the conveying channel 30, so that the reaction cup 70 in the receiving groove 22 will fall into the conveying channel 30 under the action of gravity, and then the pushing component 50 pushes the reaction cup 70 in the conveying channel 30 to the drop port 44 in turn to prepare for the next cup drop action. The present application sets a receiving mechanism 20, utilizes the cooperation of the rotating shaft 21 of the receiving mechanism 20 and the pushing mechanism, and under the action of the driving component 80 and the reaction cup 70's own gravity, the messy reaction cup 70 can be vertically transported from the loading bin 10 into the conveying channel 30, so that continuous operation will not occur.

[0042] In order to ensure that the rotating shaft 21 can completely receive the reaction cup 70 flowing out of the discharge port 11 of the loading bin 10 during the rotation process, Figure 4 As shown, the shape of the discharge port 11 is adapted to the outer circumference of the rotating shaft 21. In this way, the reaction cup 70 flowing out of the discharge port 11 can be connected to the receiving groove 22 of the rotating shaft 21, and under the action of the rotating centrifugal force, the reaction cup 70 flowing out of the discharge port 11 can be received in the groove along the extension direction of the receiving groove 22.

[0043] In addition, the inner peripheral wall of the loading bin 10 is designed with an inclined surface, and a sensor is arranged in the bin of the loading bin 10 to detect the number of reaction cups 70 in the bin so as to monitor the status of the reaction cups 70 in real time.

[0044] In order to ensure that the cuvette 70 can lie horizontally in the receiving groove 22, the extending direction of the receiving groove 22 is aligned with the axis of the rotating shaft 21. And because the gravity direction of the cuvette 70 is vertical, the conveying channel 30 is extended in the vertical direction and perpendicular to the extending direction of the receiving groove 22, so that the cuvette 70 rotating and falling from the receiving groove 22 can freely fall into the conveying channel 30 extending in the vertical direction under the action of its own gravity, thereby ensuring that the cuvette 70 can fall vertically from the conveying channel 30.

[0045] In the embodiment of the present invention, the receiving mechanism 20 further includes a roller brush 23, which is arranged corresponding to the discharge port 11 and is located above the rotating shaft 21. The length extension direction of the roller brush 23 is consistent with the axial direction of the rotating shaft 21, and the driving assembly 80 is simultaneously connected to the roller brush 23 and the rotating shaft 21. When the rotating shaft 21 is rotating, the roller brush 23 rotates simultaneously with the rotating shaft 21. When the reaction cup 70 is transferred from the loading bin 10 to the rotating shaft 21, the bristles on the roller brush 23 can exert a certain force on the reaction cup 70 to adapt the direction of the reaction cup 70 to the direction of the receiving groove 22 of the rotating shaft 21 to prevent the reaction cup 70 from getting stuck.

[0046] In an embodiment of the present invention, the driving assembly 80 includes a mounting plate 81, two synchronous wheels 82, a conveyor belt 83 and a rotating driving member; one side of the mounting plate 81 is used to mount the roller brush 23 and the rotating shaft 21; the two synchronous wheels 82 are both mounted on the other side of the mounting plate 81, and the two synchronous wheels 82 are coaxially connected to the roller brush 23 and the rotating shaft 21 respectively; the conveyor belt 83 is wound around the outer circumference of the two synchronous wheels 82; and the rotating driving member is transmission-connected to the synchronous wheels 82.

[0047] The rotating drive member is a stepper motor. When the reaction cup 70 is placed in the loading bin 10, the synchronous wheel 82 is driven to rotate by the stepper motor. The synchronous wheel 82 drives the rotating shaft 21 and the roller brush 23 to rotate simultaneously. The reaction cup 70 located at the bottom discharge port 11 is stirred in the bin body under the rotation of the rotating shaft 21, so that the reaction cup 70 falls from the discharge port 11 into the receiving groove 22 of the rotating shaft 21. As the rotating shaft 21 continues to rotate, the receiving groove 22 docked with the discharge port 11 can rotate to the top of the conveying channel 30, so that the reaction cup 70 falls vertically into the conveying channel 30 by free fall under the action of its own gravity for the next step of conveying.

[0048] In an embodiment of the present invention, the conveying channel 30 includes a vertical channel 34, a V-groove channel 32 and a blanking 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 34, the small end of the V-groove channel 32 is connected to the blanking channel 33, and one end of the blanking channel 33 is connected to the blanking port 44.

[0049] The material drop channel 33 is a long guide hole that runs through from top to bottom. The upper end of the material 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 material drop channel 33 can fall vertically into the material drop channel 33 under the action of gravity, and the bottom of the reaction cup 70 can extend from the bottom of the material 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 material drop channel 33 during the falling process of the reaction cup 70, so as to prevent the entire reaction cup 70 from sliding from the bottom of the material drop channel 33. In addition, the blanking channel 33 is extended in the front-to-back direction, so that the dropped reaction cup 70 can move toward the blanking port 44 under the push of the pushing assembly 50, and the multiple reaction cups 70 that have not fallen out of the blanking port 44 are arranged in sequence front to back along the extension direction of the blanking channel 33 to prevent the reaction cup 70 from being horizontally tilted, thereby ensuring that each reaction cup 70 can pass through the blanking port 44 in sequence, thereby avoiding cup jamming or confusion.

[0050] In an embodiment of the present invention, the conveying assembly comprises:

[0051] A conveying guide block 41 has a material drop channel 33 for sequentially arranging reaction cups 70 in a first direction, a material drop bucket 43 connected to the material drop channel 33 is provided below the end of the conveying guide block 41, and a material drop port 44 is provided at the bottom of the material drop bucket 43; and

[0052] Two inclined plates 42 are mounted on the conveying guide block 41 and are symmetrically arranged on both sides of the top of the blanking channel 33 . A V-shaped groove channel 32 communicating with the blanking channel 33 is formed between the two inclined plates 42 .

[0053] The V-groove angle of the V-groove channel 32 is between 40° and 45°. Within this angle range, the reaction cup 70 falling from the receiving groove 22 into the V-groove channel 32 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 drop channel 33, a V-groove channel 32 with a guiding function on both sides is provided between the drop channel 33 and the vertical channel 34, thereby ensuring that all the reaction cups 70 can fall vertically.

[0054] In order to prevent the reaction cup 70 in the drop channel 33 from falling, and the reaction cup 70 pushed into the drop barrel 43 needs to fall from the drop opening 44 at the bottom, the inner diameter of the drop barrel 43 needs to be designed to be larger than the width of the drop channel 33, so that the reaction cup 70 pushed from the drop channel 33 can smoothly fall from the drop opening 44 of the drop barrel 43. In addition, in order to ensure the orderly drop of the cups, the inner diameter of the drop barrel 43 is set to a size that can only accommodate one reaction cup 70, so that multiple reaction cups 70 can fall in sequence and smoothly, and there will be no confusion of multiple reaction cups 70 falling at the same time.

[0055] In summary, the present application takes into account and specifically designs the conveying guide block 41 and the V-groove channel 32, and utilizes the angle relationship of the V-groove channel 32. Under the combined action of the driving assembly 80 and the gravity of the reaction cup 70, the messy reaction cups 70 fall vertically from the drop barrel 43 into the external reaction tray to work, thereby ensuring that there is no cup jamming during continuous operation and greatly improving reliability.

[0056] like Figure 3 As shown, the pusher assembly 50 includes:

[0057] Pushing member 51;

[0058] A guide rail 52, mounted on an outer side wall of the conveying guide block 41 along a first direction;

[0059] A second linear driving member 54 is used to drive the pushing member 51 to approach or move away from the reaction cup 70 in the material dropping channel 33 along a second direction, and the first direction and the second direction intersect; and

[0060] The first linear driving member 53 is mounted on the guide rail 52 and is used to drive the second linear driving member 54 to move linearly along a first direction.

[0061] The first linear drive member 53 and the second linear drive member 54 both adopt a conventional linear drive structure in which a drive motor and a rotating screw are matched. Figure 2 The front-to-back direction in the second direction is Figure 2 A 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.

[0062] 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 drop port 44. When the reaction cup 70 reaches the drop port 44, the cup is dropped. In this reciprocating manner, the multiple reaction cups 70 in the drop channel 33 are dropped in sequence to prevent the cup from getting stuck during the cup sorting process.

[0063] In an embodiment of the present invention, the material sorting module further comprises a judging component disposed on the conveying guide block 41 , the judging component is disposed close to the material drop opening 44 and is used to judge whether a reaction cup 70 has fallen at the material drop opening 44 .

[0064] The judgment component includes a judgment optical coupler 60 and 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 fall at the drop port 44, the control unit controls the material pusher component 50 to stop pushing the next reaction cup 70; when the judgment optical coupler 60 identifies that there is no reaction cup 70 at the drop port 44, the control unit controls the material pusher component 50 to push the next reaction cup 70 to the drop port 44 to wait for falling. This method can make the reaction cup 70 fall from the drop port 44 efficiently and smoothly without causing disorder.

[0065] In an embodiment of the present invention, a sample analyzer is also provided, comprising the material arrangement module as described above.
