[0002] Mixers play a vital role in spectral analysis. Their main purpose is to evenly distribute the components in the sample through vibration, shaking, rotation, etc., to ensure that the sample reaches a uniform state before analysis, thereby improving the accuracy and reliability of the analysis results.

[0003] In the related art, an automated mixer includes an eccentric rotating shaft driven by an output end of a motor, and a container seat for placing a sample container is installed on the eccentric rotating shaft, so that the container seat and the sample container are driven by the eccentric rotating shaft to perform regular vortex motion.

[0004] Regarding the above-mentioned related technologies, in the automated workflow, in order to simplify manual steps, a robot is usually used to pick up and place the sample container on the container seat. Therefore, the position of the sample container needs to remain consistent after the mixer stops running each time. Traditional mixers can only perform mixing operations on sample containers, and the final stop position of the sample container is different, which increases the difficulty of the robot to perform high-precision picking and placing, so it needs to be improved. Summary of the Invention

[0005] In order to locate the position of the mixer after it stops, the present application provides an automatic positioning mechanism for an automated mixer.

[0006] The automatic positioning mechanism of an automated mixer provided in this application adopts the following technical solution:

[0007] An automatic positioning mechanism of an automated mixer comprises a body and an eccentric shaft rotatably arranged on the body, wherein the body is provided with a drive motor for driving the eccentric shaft to rotate; a balance ring is provided on the peripheral wall of the eccentric shaft, and the balance ring is provided with a counterweight for balancing the rotation state of the eccentric shaft; a positioning component is provided on the body for positioning the stop position of the eccentric shaft; and a detection component is provided on the body for detecting the stop position of the eccentric shaft.

[0009] Preferably, the positioning assembly includes a positioning block, a power member and a reset member; the power member is arranged on the machine body, the output shaft of the power member faces the balance ring, the positioning block is arranged on the output shaft of the power member, and the power member is used to drive the positioning block close to the eccentric shaft; the outer peripheral wall of the balance ring is provided with a positioning notch for the end of the positioning block to be pressed into, and the reset member is arranged on the output shaft of the power member to drive the output shaft of the power member away from the balance ring through its own elastic force.

[0010] By adopting the above technical solution, the power part is controlled to drive the positioning block to gradually approach the balance ring, and the reset part is elastically deformed to accumulate elastic potential energy. The positioning block and the outer peripheral wall of the balance ring rub against each other to slow down the rotation speed of the balance ring and the eccentric shaft. Finally, the positioning block gradually pushes into the positioning notch, thereby realizing rapid positioning of the eccentric shaft stop position.

[0011] Preferably, the outer peripheral wall of the balance ring is provided with a guide arc surface to facilitate the positioning block to slide into the positioning notch.

[0012] By adopting the above technical solution, the guide arc surface makes the process of the power part driving the positioning block to enter the positioning notch smoother, greatly reducing the impact force received by the positioning block when entering the positioning notch, and reducing the impact loss between the balance ring and the positioning block.

[0013] Preferably, the detection component includes a magnetic part, a detection part, a control part and a prompt part; the magnetic part is arranged on the counterweight block, and the detection part is arranged on the machine body to detect the position data of the magnetic part; the detection part and the prompt part are both controlled by the control part, and the control part is used to receive the position data of the magnetic part, and when the position data is consistent with the preset value, the prompt part is controlled to issue a prompt message.

[0014] By adopting the above technical solution, the detection member detects the position of the magnetic member, and when it is detected that the position of the magnetic member is correct, the control member and the prompt member are used to quickly prompt the user to know that the eccentric shaft has been successfully positioned and stopped.

[0015] Preferably, the side wall of the counterweight block is provided with an installation notch for the magnetic part to be inserted into, and the counterweight block is provided with a limiting component inside the installation notch for limiting the magnetic part from escaping from the installation notch, and the counterweight block is provided with an unlocking component at the installation notch for releasing the limiting component from limiting the magnetic part.

[0016] By adopting the above technical solution, the limiting component restricts the magnetic part from being separated from the installation notch to achieve stable installation of the magnetic part; the unlocking component releases the limitation of the magnetic part by the limiting component to facilitate the removal and replacement of the magnetic part.

[0017] Preferably, the limit assembly includes a mounting tube, an adsorption block, a repulsion block, an elastic member, a plug-in rod and a limit rod; the mounting tube is arranged inside the mounting notch, the adsorption block and the repulsion block are both slidably arranged inside the mounting tube, and the adsorption block is located between the magnetic member and the repulsion block; the adsorption block is magnetically attracted to the magnetic member, and the repulsion block is magnetically repelled from the magnetic member; the elastic member is arranged between the adsorption block and the repulsion block to drive the adsorption block and the repulsion block away from each other by its own elastic force; the plug-in rod is arranged on the side wall of the adsorption block facing the magnetic member, the end of the plug-in rod away from the magnetic member passes through the end wall of the mounting tube, and the side wall of the magnetic member facing the plug-in rod is provided with a plug-in groove for the plug-in rod to press into; the limit rod is arranged on the side wall of the repulsion block away from the magnetic member, the end of the limit rod away from the repulsion block passes through the end wall of the mounting tube, and the bottom wall of the mounting notch is provided with a limit groove for the limit rod to press into.

[0018] By adopting the above technical solution, after the installation cylinder is pushed into the installation notch, the magnetic part adsorbs the adsorption block, so that the plug-in rod gradually pushes into the plug-in slot, and the magnetic part repels the repulsion block, so that the limit rod gradually pushes into the limit slot; the elastic part uses its own elastic force to drive the adsorption block and the repulsion block away from each other, so that the plug-in rod and the limit rod can stably extend out of the installation cylinder, thereby realizing that the limit assembly stably restricts the magnetic part from detaching from the installation notch.

[0019] Preferably, the unlocking assembly includes a linkage rope, a traction rope and an unlocking ball; the linkage rope is arranged between the adsorption block and the repulsion block, and a passage hole is opened through the outer wall of the mounting tube, and the traction rope is passed through the passage hole. One end of the traction rope is connected to the linkage rope, and the other end of the traction rope is exposed to the mounting tube. The unlocking ball is arranged outside the mounting tube, and the unlocking ball is connected to the traction rope.

[0020] By adopting the above technical solution, the user pulls the unlocking ball and the traction rope, so that the linkage rope drives the adsorption block and the repulsion block to approach each other, so that the plug-in rod gradually disengages from the inside of the plug-in slot, and the limit rod gradually disengages from the inside of the limit slot, thereby facilitating the removal of the installation cylinder from the inside of the installation notch, and then facilitating the removal and replacement of the magnetic part.

[0021] Preferably, a buffer component for mitigating the impact force between the balance ring and the positioning block is provided on the machine body.

[0022] By adopting the above technical solution, the buffer assembly buffers the impact force between the balance ring and the positioning block, thereby reducing the damage caused by the collision between the balance ring and the positioning block.

[0023] Preferably, the buffer assembly includes a fixed shaft, a buffer block, a fixed block, a torsion piece, an extension rod and a positioning rod; the fixed shaft is arranged on the positioning block, the buffer block is rotatably arranged on the fixed shaft, the fixed block is arranged on the balance ring, and the fixed block and the buffer block are abutted against each other to limit the positioning block from disengaging from the positioning notch; the torsion piece is arranged between the fixed shaft and the buffer block to drive the buffer block to rotate toward the fixed block through its own torque; the extension rod is arranged on the fixed shaft, the positioning rod is arranged at the end of the extension rod away from the fixed shaft, and the positioning rod is abutted against the end of the buffer block away from the fixed block to limit the rotation of the buffer block.

[0024] By adopting the above technical solution, when the eccentric shaft drives the balance ring to rotate clockwise, the power part drives the positioning block and the buffer block to gradually approach the balance ring, and the buffer plate collides with the fixed block rotating clockwise, causing the torsion part to undergo elastic deformation, thereby converting part of the kinetic energy of the balance ring's rotation into the elastic potential energy of the torsion part, thereby reducing the kinetic energy and rotational speed of the balance ring, reducing the impact force between the balance ring and the positioning block when it finally stops, and reducing the phenomenon of the positioning block detaching from the positioning notch.

[0025] Preferably, the buffer assembly further comprises two groups of repulsive members, wherein one group of the repulsive members is arranged inside the fixed block, and the other group of the repulsive members is arranged inside the buffer block, and the two repulsive members repel each other magnetically.

[0026] By adopting the above technical solution, the repulsive member inside the fixed block and the repulsive member inside the buffer block repel each other, further slowing down the kinetic energy and rotation speed of the balance ring; in addition, the invisible repulsive force is used to reduce the direct hard collision between the fixed block and the buffer block, reducing the damage to the overall mechanism and ensuring the service life of the mechanism.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] By arranging a balance ring and a counterweight block to cooperate with each other, the rotation state of the eccentric shaft is balanced, so that the positioning component can stably locate the stop position of the eccentric shaft. The detection component is used to detect the stop position of the eccentric shaft, so that the user can quickly know whether the eccentric shaft has been successfully positioned and stopped, thereby realizing the automatic positioning of the stop position of the mixer;

[0029] By setting a limit assembly to limit the magnetic part from being separated from the installation notch, the magnetic part can be stably installed; the unlocking assembly releases the limit assembly from limiting the magnetic part, so that the magnetic part can be easily disassembled and replaced;

[0030] The buffer assembly is provided to buffer the impact force between the gimbal and the positioning block, thereby reducing the damage caused by the collision between the gimbal and the positioning block when the gimbal finally stops. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] Example 1:

[0040] Example 1 of the present application discloses an automatic positioning mechanism of an automated mixer, which is used to automatically locate the stop position of the mixer.

[0041] Reference Figure 1 and Figure 2An automatic positioning mechanism of an automated mixer includes a body 1 and a drive motor 12 fixedly installed inside the body 1, and an eccentric shaft 11 is fixedly sleeved on the output end of the drive motor 12. Specifically, when the output end of the drive motor 12 drives the eccentric shaft 11 to rotate counterclockwise, the sample placed on the eccentric shaft 11 is mixed. A balance ring 13 is fixedly connected to the peripheral wall of the eccentric shaft 11 by screws, and a counterweight 14 is fixedly connected to the balance ring 13, and the counterweight 14 is located on one side of the eccentric shaft 11 to balance the rotation state of the eccentric shaft 11. A positioning component 2 for positioning the stop position of the eccentric shaft 11 is installed on the body 1, and a detection component 3 for detecting the stop position of the eccentric shaft 11 is installed on the body 1, thereby realizing the stop position of the automated positioning mixer.

[0042] Reference Figure 1 and Figure 2 The positioning assembly 2 includes a positioning block 21, a power piece 22 and a reset piece 23; in this embodiment, the power piece 22 can be an electromagnet. The power piece 22 is fixedly installed inside the body 1, and the positioning block 21 is threadedly connected to the output shaft of the power piece 22. When the power piece 22 is powered on, the output shaft of the power piece 22 drives the positioning block 21 to move toward the direction close to the balance ring 13. The outer peripheral wall of the balance ring 13 is provided with a positioning notch 131 for the end of the positioning block 21 away from the power piece 22 to press into. The outer peripheral wall of the balance ring 13 is provided with a guide arc surface 132, so that when the eccentric shaft 11 drives the balance ring 13 to rotate clockwise, the positioning block 21 can slide stably into the positioning notch 131.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the reset member 23 is a spring. The reset member 23 is fixedly connected to the output shaft of the power member 22 via an anti-slip ring. One end of the reset member 23 is adhesively connected to the side wall of the power member 22 facing away from the positioning block 21, and the other end of the reset member 23 is adhesively connected to the side wall of the anti-slip ring facing the power member 22. The elastic force of the reset member 23 drives the output shaft of the power member 22 to move the positioning block 21 away from the balance ring 13, thereby achieving the reset of the positioning block 21.

[0044] Reference Figure 1 and Figure 2The detection component 3 includes a magnetic component 31, a detection component 32, a control component 33, and a prompt component 34. In this embodiment, the magnetic component 31 is a magnet, the detection component 32 is a Hall sensor, the control component 33 is a single-chip microcomputer controller, and the prompt component 34 is a prompt light. Both the detection component 32 and the prompt component 34 are electrically connected to the control component 33. The magnetic component 31 is fixedly connected to the counterweight 14, and the detection component 32 is fixedly connected to the body 1 via a support rod. The detection end of the detection component 32 is facing the eccentric shaft 11, so as to detect the position data of the magnetic component 31 and convert it into an electrical signal for output.

[0045] Reference Figure 1 and Figure 2 The control part 33 and the prompt part 34 are both installed on the body 1. The control part 33 receives the electrical signal sent by the detection part 32, and compares the internal position data of the electrical signal with the position data pre-stored in the control part 33. When the two are the same, the control part 33 controls the prompt part 34 to flash to remind the user that the eccentric shaft 11 and the balance ring 13 are successfully positioned.

[0046] The implementation principle of the automatic positioning mechanism of an automated mixer in Example 1 of the present application is as follows:

[0047] When the output end of the drive motor 12 drives the eccentric shaft 11 to rotate counterclockwise, the mixer operates normally; when the mixer stops running, the drive motor 12 stops driving, and after the speed of the eccentric shaft 11 decreases, the output end of the drive motor 12 is controlled to drive in the reverse direction, so that the output end of the drive motor 12 drives the eccentric shaft 11 and the balance ring 13 to rotate clockwise.

[0048] The control power part 22 drives the positioning block 21 to gradually approach the balance ring 13. The positioning block 21 rubs against the outer peripheral wall of the balance ring 13 and gradually presses into the positioning notch 131 through the guide arc surface 132, and controls the output end of the drive motor 12 and the balance ring 13 to stop rotating.

[0049] The detection part 32 detects the position of the magnetic part 31. After the control part 33 uses the detection part 32 to measure the correct position of the magnetic part 31, the prompt part 34 flashes to remind the user that the eccentric shaft 11 and the balance ring 13 are successfully positioned, thereby automatically achieving the purpose of the same position after each stop of the mixer.

[0050] Example 2:

[0051] The difference between Example 2 and Example 1 is that: Figure 3 and Figure 4The side wall of the counterweight block 14 is provided with an installation notch 141 for the magnetic part 31 to be inserted into. The inside of the installation notch 141 is connected to a limiting component 4 for limiting the magnetic part 31 from separating from the installation notch 141, and the counterweight block 14 is connected to an unlocking component 5 at the installation notch 141 for releasing the limit component 4 from limiting the magnetic part 31.

[0052] Reference Figure 3 and Figure 4 The limiting assembly 4 includes a mounting tube 41, an adsorption block 42, a repulsion block 43, an elastic member 44, a plug-in rod 45, and a limiting rod 46. In this embodiment, the adsorption block 42 is an iron block that is magnetically attracted to the magnetic member 31, and the repulsion block 43 is a magnet that magnetically repels the magnetic member 31, with the magnetic force of the magnetic member 31 being greater than the magnetic force of the repulsion block 43. The mounting tube 41 is located within the mounting notch 141, and the sidewalls of the mounting tube 41 are in contact with the inner sidewalls of the mounting notch 141. Specifically, the mounting tube 41 is a cylindrical block with a hollow interior and through-holes at both ends.

[0053] Reference Figure 3 and Figure 4 The adsorption block 42 and the repulsion block 43 are both slidably connected to the interior of the mounting tube 41. The adsorption block 42 is located between the magnetic member 31 and the repulsion block 43, and the magnetic poles of the repulsion block 43 and the magnetic member 31 facing each other are the same. The plug rod 45 is integrally formed on the side wall of the adsorption block 42 facing the magnetic member 31. The end of the plug rod 45 away from the magnetic member 31 passes through the end wall of the mounting tube 41. The side wall of the magnetic member 31 facing the plug rod 45 is provided with a plug slot 311 for the plug rod 45 to abut against. The side wall of the adsorption block 42 facing the plug rod 45 abuts against the inner side wall of the mounting tube 41.

[0054] Reference Figure 3 and Figure 4 The limiting rod 46 is integrally formed on the side wall of the exclusion block 43 facing away from the magnetic part 31, and the end of the limiting rod 46 away from the exclusion block 43 passes through the end wall of the mounting tube 41, and the bottom wall of the mounting notch 141 is provided with a limiting groove 142 for the limiting rod 46 to press into, and the side wall of the exclusion block 43 facing the limiting rod 46 presses against the inner wall of the mounting tube 41.

[0055] Reference Figure 3 and Figure 4 When the installation cylinder 41 drives the adsorption block 42 and the repulsion block 43 into the installation notch 141, the magnetic member 31 magnetically attracts the adsorption block 42, causing the adsorption block 42 to drive the insertion rod 45 to gradually enter the insertion slot 311. At the same time, the magnetic member 31 repels the repulsion block 43, causing the repulsion block 43 to drive the limiting rod 46 to slide into the limiting slot 142.

[0056] Reference Figure 3 and Figure 4In this embodiment, elastic member 44 is a spring. Elastic member 44 is located within mounting tube 41 and is adhesively connected between adsorption block 42 and repulsion block 43. When elastic member 44 is compressed, its own elastic force forces adsorption block 42 and repulsion block 43 to move away from each other, thereby allowing insertion rod 45 and stop rod 46 to stably extend out of mounting tube 41.

[0057] Reference Figure 3 and Figure 4 The unlocking assembly 5 includes a linkage rope 51, a pull rope 52, and an unlocking ball 53. The linkage rope 51 is glued between the attraction block 42 and the repulsion block 43. A passage hole 411 is formed through the outer wall of the mounting tube 41, communicating with the interior of the mounting tube 41. The pull rope 52 is inserted into the passage hole 411. One end of the pull rope 52 is glued to the middle of the linkage rope 51, and the other end of the pull rope 52 is exposed outside the mounting tube 41. The unlocking ball 53 is located outside the mounting tube 41. Its diameter is larger than the aperture of the passage hole 411 and is glued to the end of the pull rope 52 away from the linkage rope 51.

[0058] Reference Figure 3 and Figure 5 A buffer assembly 6 is connected to the body 1 to mitigate the impact force between the gimbal 13 and the positioning block 21. The buffer assembly 6 includes a fixed shaft 61, a buffer block 62, a fixed block 63, a torque member 64, an extension rod 65, a positioning rod 66, and two sets of repulsive members 67. In this embodiment, the buffer block 62 and the fixed block 63 are both made of rubber with good elasticity, the torque member 64 is a torsion spring, and the two sets of repulsive members 67 are two sets of magnets with the same magnetic poles.

[0059] Reference Figure 3 and Figure 5 The fixed shaft 61 is threaded onto the top of the positioning block 21, and the buffer block 62 is rotatably sleeved onto the fixed shaft 61, allowing the buffer block 62 to follow the positioning block 21 toward or away from the gimbal 13. The fixed block 63 is adhesively attached to the gimbal 13 and is located on one side of the positioning notch 131 of the gimbal 13. When the gimbal 13 drives the fixed block 63 to rotate clockwise, the fixed block 63 and the buffer block 62 collide with each other, preventing the positioning block 21 from disengaging from the positioning notch 131.

[0060] Reference Figure 3 and Figure 5The torsion member 64 is sleeved onto the fixed shaft 61, with one end of the torsion member 64 adhesively connected to the buffer block 62 and the other end of the torsion member 64 adhesively connected to the fixed shaft 61. This allows the torsion member 64 to provide torque through its own deformation and prevent the buffer block 62 from rotating away from the fixed block 63. An extension rod 65 is integrally formed on the peripheral wall of the fixed shaft 61 and is located between the buffer block 62 and the positioning block 21. A positioning rod 66 is bent and formed at the end of the extension rod 65 away from the fixed shaft 61. The positioning rod 66 abuts against the end of the buffer block 62 away from the fixed block 63 to limit the free rotation of the buffer block 62, thereby ensuring that the fixed block 63 and the buffer block 62 collide stably when the gimbal 13 rotates clockwise.

[0061] Reference Figure 3 and Figure 5 One set of repulsive members 67 is fixedly embedded in the fixed block 63, and the other set of repulsive members 67 is fixedly embedded in the buffer block 62. The two sets of repulsive members 67 magnetically repel each other, so that the repulsive force between the repulsive members 67 exerts a repulsive force on the fixed block 63 and the buffer block 62, thereby further slowing down the rotation speed of the balance ring 13.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
