It should be noted that the method steps described herein can be implemented by any functional block or functional arrangement, and any functional block or functional arrangement can be implemented as a physical entity or a logical entity, or a combination of both.

[0042] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Note: The examples described below are merely specific examples and are not intended to limit the embodiments of this utility model to the specific steps, values, conditions, data, order, etc. Those skilled in the art can utilize the concept of this utility model to construct more embodiments not mentioned herein by reading this specification.

[0044] Most similar products in the industry use grippers that move back and forth to grasp sample tubes. However, in certain specific scenarios, this technology cannot grasp sample tubes laterally. Furthermore, during the sample mixing process, due to the limited space in some emergency locations and the large rotation range of the mixing mechanism, the mixing mechanism is not convenient to work. Therefore, a mechanism for sample mixing is needed to solve the above problems.

[0045] To address the aforementioned problems in sample processing, this invention proposes a mechanism for shaking samples.

[0046] Please see Figure 1 and Figure 2 The system includes a main board 1, a Z-axis mechanism mounted on the main board 1, an X-axis mechanism connected to the Z-axis mechanism, and an R-axis mechanism connected to the X-axis. The Z-axis mechanism includes a Z-axis motor 2 mounted on the main board 1 and a lead screw 3 connected to the output end of the Z-axis motor 2. The lead screw 3 is externally threaded with a Z-axis block 4. The system also includes a slave plate 8 fixedly connected to the Z-axis block 4. The X-axis mechanism includes an X-axis motor 9 mounted on the slave plate 8 and a first transmission assembly 10 connected to the output end of the X-axis motor 9. A connecting plate 11 is mounted on the first transmission assembly 10. The system also includes a fixing plate 14 fixedly mounted on the connecting plate 11. The R-axis mechanism includes a support plate 15 fixedly connected to the fixing plate 14 and an R-axis motor 16 mounted on the support plate 15.

[0047] like Figure 1 and Figure 2 As shown, it mainly consists of a Z-axis mechanism, an X-axis mechanism, and an R-axis mechanism. The Z-axis mechanism enables vertical movement, while the X-axis mechanism enables horizontal movement, and the R-axis mechanism enables the gripper assembly 20 to rotate, thus shaking the sample evenly.

[0048] Specifically, the Z-axis mechanism is mounted on the main board 1. The Z-axis motor 2 in the Z-axis mechanism is mounted on the top of the cross arm of the main board 1. The lead screw 3 connected to the Z-axis motor 2 is vertically set, and a Z-axis plate is sleeved on the outside of the lead screw 3, so that the Z-axis plate can move up and down. At the same time, the X-axis mechanism is connected to the Z-axis plate, which can drive the X-axis mechanism to move up and down. The X-axis mechanism uses an X-axis motor 9 and a first transmission component 10 on it. The first transmission component 10 can move laterally. At the same time, the R-axis mechanism is connected to the first transmission component 10 through a connecting plate 11. When the first transmission component 10 moves laterally, it can drive the R-axis mechanism to move laterally. At the same time, the R-axis mechanism uses an R-axis motor 16, which can drive the gripper component 20 to rotate, so as to shake the sample evenly.

The vertical arm of the main board 1 is located on one side of the Z-axis block 4 and is equipped with a Z-axis guide rail 5. The Z-axis block 4 and the Z-axis guide rail 5 are slidably connected. The vertical arm of the main board 1 is fixed with a base 6 at the bottom of the lead screw 3. The lead screw 3 is rotatably mounted on the base 6. The horizontal arm of the main board 1 is equipped with a Z-axis optical coupler 7. The Z-axis block 4 and the Z-axis optical coupler 7 are movably connected.

[0050] like Figure 1 and Figure 2 As shown, the main board 1 has an L-shaped structure, specifically an inverted L-shaped structure. The Z-axis motor 2 is mounted on the top of the horizontal arm of the main board 1. The vertical arm of the main board 1 is equipped with a Z-axis guide rail 5 and a base 6 on one side of the Z-axis plate, allowing the Z-axis block 4 to slide on the Z-axis guide rail 5 and move up and down. The bottom of the lead screw 3 is rotatably connected to the base 6, so that the Z-axis block 4 can move up and down during the rotation of the lead screw 3. At the same time, a Z-axis optocoupler 7 is provided on the horizontal arm of the main board 1, which can sense the moving position of the Z-axis block 4.

[0051] Please continue reading. Figure 1 and Figure 2 The first transmission assembly 10 includes a first driving wheel connected to the output end of the X-axis motor 9 and a first driven wheel rotated on the driven plate 8. A first synchronous belt is sleeved between the first driving wheel and the first driven wheel, and the connecting plate 11 is connected to the first synchronous belt.

[0052] like Figure 1 and Figure 2 As shown, the X-axis motor 9 drives the driving wheel to rotate, and the driven wheel is mounted on the slave plate 8. A first synchronous belt is sleeved between the driven wheel and the driving wheel, so that the first driving wheel can drive the first driven wheel to rotate through the first synchronous belt. During the movement of the first synchronous belt, it drives the connecting plate 11 connected to the first synchronous belt to move, so that the connecting plate 11 drives the fixed plate 14 to move.

[0053] Please continue reading. Figure 1 and Figure 2 An X-axis optical coupler 12 is installed on the plate 8. The connecting plate 11 is movably connected to the X-axis optical coupler 12. The plate 8 also has an L-shaped structure. An X-axis guide rail 13 is laid on one side of the connecting plate 11, and the connecting plate 11 slides on the X-axis guide rail 13.

[0054] like Figure 1 and Figure 2 As shown, the X-axis optical coupler 12 can sense the position of the connecting plate 11, prevent the connecting plate 11 from moving to other positions, and lay the X-axis guide rail 13 on one side of the connecting plate 8, so that the connecting plate 11 slides on the X-axis guide rail 13, and the connecting plate 11 can move along the X-axis guide rail 13.

[0055] Please continue reading. Figure 1 and Figure 2The fixed plate 14 is fixedly provided with an R-axis rotating seat 18 on one side of the support plate 15. The R-axis rotating seat 18 is located below the support plate 15. A second transmission assembly 17 is installed between the R-axis rotating seat 18 and the support plate 15. The second transmission assembly 17 includes a second driving wheel rotated on one side of the support plate 15 and a second driven wheel rotated on one side of the R-axis rotating seat 18. A second synchronous belt is sleeved between the second driving wheel and the second driven wheel. The second driving wheel is connected to the output end of the R-axis motor 16.

[0056] like Figure 1 and Figure 2 As shown, the R-axis rotating seat 18 and the support plate 15 are arranged one above the other, so that the second transmission component 17 is mounted on the R-axis rotating seat 18 and the support plate 15, while the second driven wheel is mounted on the R-axis rotating seat 18. During the rotation of the second driving wheel, it drives the second synchronous belt to move, which in turn drives the second driven wheel to rotate, causing the rotating plate 19 to rotate.

[0057] Please continue reading. Figure 1 and Figure 2 A rotating plate 19 is fixed at one end of the second driven wheel. A gripper assembly 20 is installed on one side of the rotating plate 19. The gripper assembly 20 includes two clamps rotatably mounted on the rotating plate 19 and a tension spring between the two clamps. An R-axis optical coupler 21 is installed on the R-axis rotating seat 18. The rotating plate 19 is movably connected to the R-axis optical coupler 21.

[0058] like Figure 1 and Figure 2 As shown, one side of the rotating plate 19 rotates with the second driven wheel, and can rotate with the second driven wheel. At the same time, two clamping plates are rotated at the bottom of one side of the rotating plate 19. The two clamping plates are symmetrically arranged to form a gripper structure, and a tension spring is provided between the two clamping plates to clamp the sample, which makes it easy for the rotating plate 19 to rotate and shake evenly.

[0059] When using this utility model, the X-axis mechanism is installed on the Z-axis mechanism. The Z-axis mechanism is responsible for dragging the X-axis mechanism to achieve the up-and-down reciprocating motion, while the X-axis mechanism is responsible for dragging the R-axis mechanism to move laterally, so that the R-axis can grasp the sample tube. At the same time, the R-axis mechanism can shake the sample tube to achieve the function of mixing.
