[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 90-degree transfer method of the reaction cup described in the present invention is achieved by a 90-degree transfer device.

[0020] like Figure 1-5 As shown, the above-mentioned 90-degree transfer device includes a support frame 1, on which one or more ejectors 2 arranged in parallel are installed, and each ejector 2 is equipped with a rotating disk 3 and an associated component.

[0021] Specifically, two horizontally arranged mounting grooves are provided on the fixed block at the lower part of the support frame 1, and a rotating disk 3 is installed in each mounting groove. A cuvette transport channel m arranged radially is provided in each rotating disk 3. The cuvette transport channel m is a through groove having a horizontal input position and a vertical output position. Therefore, a horizontal cuvette input channel n1 which is connected to the cuvette transport channel m, two vertical cuvette output channels n2 which are respectively connected to the outlets of the cuvette transport channel m, and a push channel n3 which is located above the rotating disk 3 and is coaxially arranged with the cuvette output channel n2 are also provided on the fixed block. A rotating connector 4 is also provided on each rotating disk 3, which is located on the mid-vertical line of the cuvette transport channel m, that is, eccentrically connected to the rotating disk 3.

[0022] The front side of the support frame 1 is equipped with an ejector 2 whose end is located in the push channel n3. The ejector 2 adopts a linear guide rail, which is connected to the synchronous belt mechanism 5 (i.e., a reciprocating mechanism) installed on the back of the support frame 1. Driven by the motor, the synchronous belt of the synchronous belt mechanism 5 can rotate forward or reverse, and the ejector 2 will fall and rise accordingly. The ejector 2 is equipped with a first slider 21 and a second slider 22. The first slider 21 is fixedly connected to the associated component, and the second slider 22 is fixedly set in the push channel n3, so that the ejector 2 can move smoothly in the push channel n3. The ejector 2 is also equipped with a straight connecting member 6, which 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.

[0023] The connecting assembly includes a connecting member 7 , a linear connecting member 6 and a rotating connecting member 4 .

[0024] 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.

[0025] A linear guide groove 72 and a turning guide groove 73 are sequentially arranged below the permanent magnet 71 .

[0026] 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.

[0027] 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.

[0028] An initialization sensor 8 is installed on the above-mentioned support frame 1, and the control unit can send a control signal for initialization action according to the position of the ejector 2 detected by it; an in-position sensor 9 is installed on the rotating disk 3, and when it detects that the reaction cup enters the reaction cup transfer channel m and is installed in place, the control unit can send a control signal for ninety-degree rotation.

[0029] When the above-mentioned 90-degree transfer device is in the initial state, the reaction cup transfer channel m is in the horizontal input position and is connected with the reaction cup input 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 can be fed into the reaction cup transfer channel m of the rotating disk 3 through the reaction cup input channel n1, so that the reaction cup is in place in the rotating disk 3.

[0030] The 90-degree transfer method of the present invention is performed by the 90-degree transfer device and mainly comprises the following steps: 1) The reaction cup is in place: when the 90-degree transfer device is in the initialization state, the reaction cup is fed into the reaction cup transfer channel m of the rotating disk through the reaction cup input channel n1, so that the reaction cup is in place in the rotating disk 3.

[0031] 2) The reaction cup transport channel m rotates 90 degrees: the synchronous belt mechanism 5 is started to move the ejector 2 downward along the push 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 reaction cup transport channel m is rotated from the horizontal input position to the vertical output position.

[0032] 3) 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.

[0033] 4) Initialization: The synchronous belt mechanism 5 is started 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 reaction cup transfer channel m is turned from the vertical output position to the horizontal input position, and the initialization is completed.

[0034] 5) Repeat steps 1-4.

[0035] The left and right transfer mechanisms in this embodiment can simultaneously transfer the reaction cup at a 90-degree angle, or can independently transfer the reaction cup at a 90-degree angle. Figure 5 The figure shows the process of the left transport mechanism alone transporting the reaction cup 90 degrees.

[0036] 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.
