[0018] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific working process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0019] The reaction cup transport adjustment method of the present invention is implemented by a reaction cup transport adjustment device.

[0020] like Figure 1-6 As shown, the reaction cup transport adjustment device includes a support base 1, and a reaction cup conveying channel n1 is arranged at the right end of the support base 1. The above-mentioned reaction cup conveying channel n1 is used to convey reaction cups K arranged in a single row and connected head to tail. A cup supply mechanism is arranged at the inlet end of the reaction cup conveying channel n1, a conveyor belt mechanism is arranged in the middle of the reaction cup conveying channel n1, and a ninety-degree transport mechanism is arranged at the outlet end of the reaction cup conveying channel n1.

[0021] The cup supply mechanism is used to sort the disordered cuvettes K so that they enter the cuvette conveying channel n1 in a certain posture and are conveyed in a single row. The conveyor belt mechanism is used to provide power for the cuvette K to move forward. In this embodiment, the conveyor belt mechanism includes a driving wheel and a driven wheel driven by a motor, and an annular conveyor belt is connected between the two. The top surface of the conveyor belt is connected to the bottom of the horizontally placed cuvette K. When the conveyor belt rotates counterclockwise, the cuvette K moves to the left along the cuvette conveying channel n1.

[0022] The 90-degree transfer mechanism is used to turn the horizontally placed reaction cup K 90 degrees so as to supply it to the subsequent workstation. It includes one or more ejectors 2 (two in this embodiment) arranged in parallel. Each ejector 2 is equipped with a rotating disk 3 and an associated component.

[0023] The rotating disk 3 is arranged side by side along the cuvette transport channel n1, and is located on the left side of the support seat 1. Specifically, a mounting groove adapted to the rotating disk 3 is provided on the support seat 1, and a rotating disk 3 is installed in each mounting groove, and a cuvette transport channel m arranged radially is provided in each rotating disk 3. The cuvette transport channel m is a through groove, which has a horizontal input position and a vertical output position. Therefore, in addition to the cuvette transport channel n1 arranged horizontally and connected with the cuvette transport channel m, a vertical cuvette output channel n2 and a push channel n3 are arranged around each rotating disk 3 on the support seat 1. Among them, the cuvette output channel n2 is located on the opposite side of the ejector 2 (i.e., below the rotating disk 3), and is connected with the cuvette transport channel m at the output position; the push channel n3 is coaxial with the cuvette output channel n2, and is arranged on the same side as the ejector 2 (i.e., above the rotating disk 3), and the end of the ejector 2 is arranged in the push channel n3. Each rotating disk 3 is also provided with a rotating connector 4 , which is located on the mid-vertical line of the reaction cup transport channel m, that is, eccentrically connected to the rotating disk 3 .

[0024] The ejector 2 is correspondingly arranged above each rotating disk 3, and is connected to the synchronous belt mechanism 5 (i.e., reciprocating mechanism) installed on the back of the support seat 1. Driven by the motor, the synchronous belt of the synchronous belt mechanism 5 can rotate forward or reverse, and the ejector 2 will drop and rise accordingly. The ejector 2 usually adopts a linear guide rail, on which a first slider 21 and a second slider 22 are installed (or, an optical axis is used as the ejector, and a linear bearing is installed thereon as the first slider and the second slider), wherein the first slider 21 is fixedly connected to the associated component, and the second slider 22 is fixedly arranged in the push channel n3, so that the ejector 2 can move smoothly in the push channel n3. A straight connecting member 6 is also installed on the ejector 2, and the straight connecting member 6 is an L-shaped structural member arranged in the middle of the ejector, and is composed of an attachment section located on the ejector 2 and a horizontal extension section protruding outward from the ejector 2.

[0025] The connecting assembly includes a connecting member 7 , a linear connecting member 6 and a rotating connecting member 4 .

[0026] The above-mentioned connecting member 7 is used to connect the ejector 2 and the rotating disk 3. It is slidably connected to the ejector 2 through the first slider 21, so that the two can move relatively smoothly. At the same time, the connecting member 7 is also provided with a permanent magnet 71, which is used to absorb the attachment section of the ejector 2 (the attachment section is made of special materials or has an iron coating on the surface), so that the connecting member 7 and the ejector 2 can maintain a fixed connection relationship under certain conditions and move at the same time.

[0027] A linear guide groove 72 and a turning guide groove 73 are sequentially arranged below the permanent magnet 71 .

[0028] The linear guide groove 72 is arranged in the same direction as the ejector 2 (i.e., vertically), and is used to connect the straight connecting member 6 on the ejector 2. The horizontal extension section of the straight connecting member 6 is arranged in the linear guide groove 72 and is adapted to the width of the linear guide groove 72. Normally, the horizontal extension section of the straight connecting member 6 is located at the top of the linear guide groove 72, at which time, the connecting member 7 and the ejector 2 move synchronously; the horizontal extension section of the straight connecting member 6 can also move freely along the linear guide groove 72, at which time, the connecting member 7 is in a fixed state, while the ejector 2 moves freely in the pushing channel n3, and is relatively displaced with the connecting member 7.

[0029] The turning guide groove 73 includes a first stroke segment, a second stroke segment and a third stroke segment connected in sequence, wherein the first stroke segment is coaxially arranged with the reaction cup transport channel m in the output position, the third stroke segment is parallel to the first stroke segment (both are arranged vertically), and the second stroke segment is a smooth arc structure connecting the first stroke segment and the third stroke segment, and the spacing between the first stroke segment and the third stroke segment is equal to the eccentricity of the rotating connector 4. The rotating connector 4 on the rotating disk 3 is connected to the turning guide groove 73 through a bearing. When the linking member 7 moves in the vertical direction relative to the rotating disk 3, the rotating connector 4 moves along the turning guide groove 73, thereby rotating the rotating disk 3, and then completing the conversion of the reaction cup transport channel m between the input position and the output position.

[0030] The support base 1 is also provided with an initialization sensor 8 , an in-position sensor 9 , a full cup sensor 10 and a cup-missing sensor 11 .

[0031] Among them, the initialization sensor 8 is arranged close to the ejector 2, and is used to detect the high position and the low position of the ejector 2; when the ejector 2 is in the high position, the ninety-degree transfer mechanism is in the initial state, and the initialization sensor 8 sends a signal to the control unit to start the conveyor mechanism, so that the reaction cup K is transferred from the reaction cup conveying channel n1 to the reaction cup transfer channel m; when the ejector 2 is in the low position, the reaction cup K is pushed out of the reaction cup transfer channel m, and the initialization sensor 8 sends a signal to the control unit to start the ninety-degree transfer mechanism and perform the initialization action of the ninety-degree transfer mechanism (from the vertical position to the horizontal position).

[0032] The in-place sensor 9 is installed near the rotating disk 3 and is used to detect whether the cuvette K in the cuvette conveying channel n1 is in place in the cuvette transfer channel m at the input position (i.e., horizontal direction); when the in-place sensor 9 sends a signal to the control unit, the conveyor belt mechanism stops running, and the 90-degree transfer mechanism starts, so that the cuvette K is adjusted in posture (from horizontal position to vertical position).

[0033] The full cup sensor 10 and the missing cup sensor 11 are both installed near the conveyor belt mechanism of the reaction cup conveying channel n1, and the missing cup sensor 11 is located at the front side of the full cup sensor 10 (that is, the missing cup sensor 11 is arranged closer to the rotating disk 3). When the full cup sensor 10 sends a signal to the control unit, the cup supply mechanism at the inlet end of the reaction cup conveying channel n1 suspends operation; when the missing cup sensor 11 sends a signal to the control unit, the cup supply mechanism resumes operation.

[0034] When the above-mentioned 90-degree transfer mechanism is in the initial state, the reaction cup transfer channel m is in the horizontal input position and is connected with the reaction cup delivery channel n1; the rotating connector 4 is located directly above the rotating disk 3 and at the starting end of the first stroke section of the turning guide groove 73; the connecting member 7 and the ejection member 2 are adsorbed together by the magnet 71, and the straight connection member 6 is located at the top of the linear guide groove 72. At this time, the reaction cup K can be fed into the reaction cup transfer channel m of the rotating disk 3 through the reaction cup delivery channel n1, so that the reaction cup is in place in the rotating disk 3.

[0035] The following is a detailed description of the process of the present invention for completing the 90-degree transfer of the reaction cup (see Figure 6 ) for detailed explanation.

[0036] 1) Feeding of reaction cups: starting the cup feeding mechanism and the conveyor belt mechanism to feed the reaction cup conveying channel n1; when the full cup sensor 10 sends a signal to the control unit, the cup feeding mechanism is suspended; when the empty cup sensor 11 sends a signal to the control unit, the cup feeding mechanism is started again; 2) Cuvette in place: After the 90-degree transfer mechanism is initialized, the ejector 2 is in a high position, the initialization sensor 8 sends a signal, and the conveyor belt mechanism in the middle of the cuvette conveying channel n1 is started through the control unit. The cuvette K is fed from the cuvette conveying channel n1 to the cuvette transfer channel m of the rotating disk 3, completing the placement of the cuvette K in the rotating disk 3.

[0037] 3) The cuvette transport channel m rotates 90 degrees: After the cuvette K is in place in the rotating disk 3, the arrival sensor 9 sends a signal, and the conveyor belt mechanism stops running through the control unit, and the synchronous belt mechanism 5 is started at the same time, and the ejector 2 moves downward along the pushing channel n3, and the associated member 7 moves downward synchronously with the ejector 2; the straight connecting member 6 is still located at the top of the linear guide groove 72, and the rotating connecting member 4 moves from the starting end of the first stroke segment of the turning guide groove 73 to the ending end of the third stroke segment. In this process, the cuvette transport channel m is transferred from the horizontal input position to the vertical output position.

[0038] 4) Cuvette output: The ejector 2 continues to move downward along the push channel n3. During this process, the connecting member 7 and the rotating disk 3 do not move, and the straight connecting member 6 releases the magnetic attraction from the connecting member 7. It moves downward along the linear guide groove 72 and moves relative to the connecting member 7 until the ejector 2 sends the cuvette out of the cuvette output channel n2.

[0039] 5) Initialization: After the ejector 2 sends the cuvette K out of the cuvette output channel n2, the ejector 2 is in a low position, and the initialization sensor 8 sends a signal again. The control unit starts the synchronous belt mechanism 5 again, driving the ejector 2 to move upward. When the straight connecting member 6 moves to the top of the linear guide groove 72, it and the associated member 7 are attracted by the magnet 71 again; the ejector 2 continues to move upward, and the associated member 7 moves upward synchronously with the ejector 2. The rotating connecting member 4 gradually moves from the end end of the third stroke segment of the turning guide groove 73 to the starting end of the first stroke segment. In this process, the cuvette transport channel m is turned from the vertical output position to the horizontal input position, and the initialization is completed.

[0040] 6) Repeat steps 2-5 until all reaction cups are transferred.

[0041] The two left and right sets of 90-degree transfer mechanisms in this embodiment can simultaneously transfer the reaction cup at a 90-degree angle, or can transfer the reaction cup at a 90-degree angle independently. Figure 6 The figure shows the process of the left transport mechanism alone transporting the reaction cup 90 degrees.

[0042] The present invention is very suitable for the reaction cup supply of a chemiluminescent immunoassay analyzer, can make the chemiluminescent immunoassay analyzer run stably, and effectively improve the detection efficiency of the chemiluminescent immunoassay analyzer.

[0043] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
