The driving mechanism 2 and the origin detection assembly 6 are both electrically connected to the external controller. When working, the origin detection assembly 6 transmits the detected origin positioning information to the external controller, and the external controller issues a command to control the required rotation angle of the driving mechanism 2.

[0038] like Figure 3 and Figure 4 As shown, the base 1 includes a bottom substrate 1-1, a driving mechanism 2 is arranged on the bottom substrate 1-1, a first side plate 1-2 and a second side plate 1-3 are arranged at both ends of the bottom substrate 1-1, and the first side plate 1-2 and the second side plate 1-3 are rotatably connected to the rotating shaft 4-2 respectively.

[0039] The frame 4-1 is provided with a plurality of liquid guiding grooves 4-3, and the positions of the liquid guiding grooves 4-3 correspond to the test tubes 5. When performing the liquid pouring operation, the liquid guiding grooves 4-3 can prevent splashing during the liquid pouring process, and play a role in drainage and buffering. In this embodiment, the frame 4-1 adopts a hollow structure, which can play a role in reducing the overall weight.

[0040] The driving mechanism 2 includes a motor 2-1, which is arranged on the bottom substrate 1-1. The output end of the motor 2-1 is provided with a driving pulley 2-2, which is connected to the passive pulley 2-3 through a synchronous belt 2-4, and the passive pulley 2-3 is fixedly connected to the rotating shaft 4-2. When the motor 2-1 is started, the driving pulley 2-2 drives the passive pulley 2-3 and the rotating shaft 4-2 to rotate through the synchronous belt 2-4, and then drives the frame 4-1 to rotate, so as to achieve the vibration and shaking of the test tube 5.

[0041] The brake assembly 7 includes a brake 7-1, which is electrically connected to an external controller, and is tightly matched with the rotating shaft 4-2, and is fixedly connected to the first side plate 1-2. In this embodiment, the brake 7-1 is an electromagnetic brake connected to an external power supply, and when the brake 7-1 tightly holds the rotating shaft 4-2, it can brake the rotating frame 4-1.

[0042] like Figures 4 to 6 As shown, the origin detection assembly 6 includes a detection disk 6-1 and a photoelectric switch 6-2, the detection disk 6-1 is fixedly connected to the rotating shaft 4-2, and the photoelectric switch 6-2 is fixedly connected to the second side plate 1-3. The detection disk 6-1 and the photoelectric switch 6-2 are used together to effectively feedback the real-time position of the shaking table and determine the origin. In this embodiment, the photoelectric switch 6-2 is a slot-type photoelectric switch.

[0043] In this embodiment, the motor 2-1 is a stepper motor, and the motor 2-1, the detection disk 6-1 and the photoelectric switch 6-2 are all electrically connected to an external controller. A light-transmitting light-transmitting structure 6-1-1 is provided on the detection disk 6-1, wherein the light-transmitting structure 6-1-1 is a light-transmitting slot. When the light-transmitting structure 6-1-1 is located at the origin position of the motor 2-1, i.e., the starting position when the motor 2-1 is stationary, the light signal emitted by the photoelectric switch 6-2 passes through the light-transmitting structure 6-1-1 and is received by the photoelectric switch 6-2. When the motor 2-1 rotates, the detection disk 6-1 rotates with the rotating shaft 4-2. Each time the photoelectric switch 6-2 detects a light signal passing through the light-transmitting structure 6-1-1, it can be determined as a full rotation, i.e., the motor 2-1 returns to the zero position again, and the controller can control the number of steps of the motor 2-1 according to the signal received by the photoelectric switch 6-2 to control the rotation angle of the motor 2-1.

[0044] like Figure 5As shown, a plurality of electromagnets 8 are arranged on the frame 4-1, and the electromagnets 8 are arranged on one side of the test tubes 5, and the electromagnets 8 correspond to the test tubes 5 one by one. When the electromagnets 8 are energized, a magnetic field is generated, and the magnetic field acts on the reagents in the test tubes 5, which is often used in magnetic bead method nucleic acid extraction experiments. Its purpose is to be used for the extraction, enrichment and purification of viral nucleic acids in various types of biological samples.

[0045] The electromagnet 8 is connected to the external power supply through the conductive slip ring 9, and the conductive slip ring 9 is arranged on the rotating shaft 4-2. Specifically, the conductive slip ring 9 includes a stator and a rotor, and the rotor can rotate 360 ​​degrees relative to the stator, and the two are electrically connected, the stator is connected to a stator wire, and the rotor is connected to a rotor wire. The stator of the conductive slip ring 9 is fixedly connected to the second side plate 1-3, and the stator wire is connected to the external power supply; the rotor of the conductive slip ring 9 is fixedly connected to the rotating shaft 4-2 and rotates synchronously with the rotating shaft 4-2, and the rotor wire is connected to the electromagnet 8, and the conductive slip ring 9 is used to realize continuous power supply to the electromagnet 8 that rotates synchronously with the frame 4-1.

[0046] like Figures 7 to 10 As shown, the locking device 3 includes a front pressure cover 3-1 and a buckle 3-2, and the buckle 3-2 is tightly matched with the front pressure cover 3-1 to ensure that the test tube 5 will not loosen or fall off during the rotation process.

[0047] The buckle 3-2 includes a buckle plate 3-2-1, both ends of which are rotatably connected to the side plates of the frame 4-1 through a pin shaft, a slot 3-2-3 is provided at the lower end of the buckle plate 3-2-1, and a spring 3-2-2 is provided at the upper end of the buckle plate 3-2-1, one end of the spring 3-2-2 is fixedly connected to the buckle plate 3-2-1, and the other end of the spring 3-2-2 is fixedly connected to the top frame 4-1.

[0048] The two ends of the front pressure cover 3-1 are rotatably connected to the side plates of the frame body 4-1 through pins, and arc-shaped limit grooves 3-1-2 are provided at both ends of the front pressure cover 3-1. The side plates of the frame body 4-1 are provided with protrusions that are slidably connected to the arc-shaped limit grooves 3-1-2, and the arc-shaped limit grooves 3-1-2 limit the rotation range of the front pressure cover 3-1. A clamping strip 3-1-1 is provided at the top of the front pressure cover 3-1, and the clamping strip 3-1-1 is clamped and matched with the clamping slot 3-2-3.

[0049] A clamping arm 3-1-3 is provided in the front gland 3-1 at the position corresponding to the test tube 5, and there are two clamping arms 3-1-3 at the position corresponding to each test tube 5. The clamping arm 3-1-3 is provided with an arc-shaped clamping surface with anti-slip grooves for clamping the test tube 5. The clamping arm 3-1-3 is rotatably connected to the column 3-1-4, and the column 3-1-4 is fixedly connected to the gland frame 3-1-7. A clamping tension spring 3-1-6 is fixedly connected between the two clamping arms 3-1-3, and the elastic force of the clamping tension spring 3-1-6 can enable the two clamping arms 3-1-3 to clamp the test tube 5. A limiting column 3-1-5 fixedly connected to the capping frame 3-1-7 is also provided between the two clamping arms 3-1-3. When the clamping arms 3-1-3 are not in contact with the test tube 5, the limiting column 3-1-5 can prevent the two clamping arms 3-1-3 from closing due to the elastic force of the clamping tension spring 3-1-6, so that the two clamping arms 3-1-3 still maintain a certain opening angle to facilitate the next clamping of the test tube 5.

[0050] When it is necessary to fasten the test tube 5, first insert the test tube 5 to the bottom, rotate the front gland 3-1 inward, and insert the clamping strip 3-1-1 of the front gland 3-1 into the clamping slot 3-2-3 of the clamp 3-2. The clamping plate 3-2-1 rotates inward and upward, and the spring 3-2-2 is compressed. The clamping strip 3-1-1 squeezes into the inner side of the clamping slot 3-2-3. Then, the clamping plate 3-2-1 can fasten the front gland 3-1 under the elastic force of the spring 3-2-2 to prevent the front gland 3-1 from jumping out. At the same time, the clamping arm 3-1-3 corresponding to the test tube 5 opens under the pressure, and clamps the test tube 5 under the elastic force of the clamping tension spring 3-1-6 to prevent the test tube 5 from shaking.

[0051] like Figures 1 to 10 As shown, the use process of the present invention is as follows:

[0052] First, set the rotation angle and speed parameters on the controller in advance, and ensure that the speed parameters are within the specified speed so that the solvent in the test tube 5 cannot be shaken evenly due to centrifugal force. Install the test tube 5 on the frame 4-1, cover the front cover 3-1, and lock the test tube 5 with the buckle 3-2. Start the motor 2-1, and the active pulley 2-2 drives the passive pulley 2-3 and the rotating shaft 4-2 to rotate through the synchronous belt 2-4, thereby driving the frame 4-1 to rotate 360° continuously. The controller can determine the number of rotations and the origin position of the motor 2-1 based on the light signal received by the photoelectric switch 6-2 through the light-transmitting structure 6-1-1. At the same time, the final rotation angle of the motor 2-1 can be controlled by controlling the number of steps of the motor 2-1, thereby achieving the oscillation and shaking of the test tube 5. When it is necessary to stop, the brake 7-1 is started to brake the frame 4-1.

[0053] In addition, the parameters can be set with the help of the controller so that the shaker can swing back and forth within any angle range to ensure the oscillation and shaking effect.

[0054] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
