[0046] The embodiment of the present application provides a mixing device that can automatically mix samples in a container and reduce the labor intensity of experimenters.

[0047] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0048] like Figures 1 to 3 As shown, the embodiment of the present application provides a mixing device, including a clamping mechanism 1 and a rotating mechanism 2. The clamping mechanism 1 includes a first clamping jaw 11 for clamping the side wall of the container 4, and a second clamping jaw 12 for clamping the two opposite ends of the container 4. The first clamping jaw 11 can open and close in a first direction. Figure 1 In the X-axis direction shown in FIG, the second clamping jaw 12 can open and close in the second direction, such as the second direction is Figure 1 The Z-axis direction shown in FIG, the first direction and the second direction are perpendicular. Wherein, the second direction is parallel to the axis direction of the container 4, and the first direction is perpendicular to the axis direction of the container 4, as shown in FIG. Figure 1 As shown, before the mixing device is in operation, the container 4 can be placed vertically, with the lid 5 provided at the upper end of the container 4. The second clamping jaw 12 clamps the upper and lower ends of the container 4. Specifically, the second clamping jaw 12 abuts against the bottom of the container 4 and the lid 5 at the upper end of the container 4, respectively. The first clamping jaw 11 clamps the body of the container 4. The container 4 can include, but is not limited to, a volumetric flask, a flask, a test tube, a centrifuge tube, etc.

[0049] The rotating mechanism 2 is connected to the clamping mechanism 1 and is used to drive the clamping mechanism 1 to rotate so as to drive the container 4 to rotate. The rotation axis of the clamping mechanism 1 is perpendicular to the second direction. For example, the rotation axis of the clamping mechanism 1 is Figure 1 The Y-axis direction is shown in FIG.

[0050] Based on the above scheme, the side wall of the container 4 is clamped by the first clamping jaw 11, and the two opposite ends of the container 4 are clamped by the second clamping jaw 12. In this way, the container 4 is clamped together in the first direction and the second direction, which are two perpendicular directions, and the container 4 is clamped more firmly. When the second clamping jaw 12 clamps the two opposite ends of the container 4, the cover 5 on the container 4 can be clamped and fastened to the container 4 to prevent the cover 5 from being separated from the container 4 when the container 4 is shaken; the clamping mechanism 1 is driven to rotate by the rotating mechanism 2 to drive the container 4 to rotate, thereby shaking the container 4 to mix the sample in the container 4 evenly. Therefore, the above mixing device does not need to manually shake the container 4, which can reduce the labor intensity of the experimenter, make the sample mixing more even, and can be used in automated experimental equipment to improve experimental efficiency.

[0051] In some embodiments, as Figure 1 As shown, the first clamping jaw 11 includes a first driving member 111 and two first clamping arms 112 arranged opposite to each other, and a first clamping space 113 for accommodating the side wall of the container 4 is formed between the two first clamping arms 112. The first driving member 111 is drivingly connected to at least one first clamping arm 112, and the first driving member 111 is used to drive the two first clamping arms 112 to move relatively closer or farther in a first direction to adjust the size of the first clamping space 113.

[0052] Specifically, when the first clamping jaw 11 grips the sidewall of the container 4, the first driving member 111 can drive one of the first clamping arms 112 toward the other first clamping arm 112, thereby reducing the width of the first clamping space 113 until both first clamping arms 112 grip the sidewall of the container 4. When the first clamping jaw 11 grips the sidewall of the container 4, the first driving member 111 can also simultaneously drive both first clamping arms 112 toward each other, thereby gripping the sidewall of the container 4. Similarly, when the first clamping jaw 11 needs to release the container 4, the first driving member 111 can drive one of the first clamping arms 112 away from the other first clamping arm 112, or simultaneously drive both first clamping arms 112 toward each other, thereby increasing the size of the first clamping space 113. The first driving member 111 can be driven by a motor or a cylinder, without limitation. The first clamping arm 112 can be plate-shaped, block-shaped, or any other feasible structure, without limitation. The first clamping arm 112 has a clamping surface on one side facing the first clamping space 113 . The clamping surface may be V-shaped, arc-shaped, U-shaped, or any other shape that can match the side wall of the container 4 , which is not limited here.

[0053] In some embodiments, as Figure 1 and Figure 2As shown, the second clamping jaw 12 includes a second driving member 121 and two second clamping arms 122 arranged opposite to each other, and a second clamping space 123 for accommodating the two opposite ends of the container 4 is formed between the two second clamping arms 122. The second driving member 121 is drivingly connected to at least one second clamping arm 122, and the second driving member 121 is used to drive the two second clamping arms 122 to move relatively closer or farther in the second direction to adjust the size of the second clamping space 123.

[0054] Specifically, when the second clamping jaw 12 clamps the two opposite ends of the container 4, the second driving member 121 can drive one of the second clamping arms 122 to move toward the other second clamping arm 122, or the second driving member 121 can simultaneously drive the two second clamping arms 122 to move toward each other, thereby reducing the width of the second clamping space 123 until the two second clamping arms 122 clamp the two opposite ends of the container 4. Similarly, when the second clamping jaw 12 needs to release the container 4, the second driving member 121 can drive one of the second clamping arms 122 to move away from the other second clamping arm 122, or simultaneously drive the two second clamping arms 122 to move away from each other, thereby increasing the size of the second clamping space 123.

[0055] In some embodiments, as Figure 1 and Figure 2 As shown, the second driving member 121 includes two driving motors 1211, two screw rods 1212 arranged along the second direction, two nuts 1213 respectively arranged on the two screw rods 1212, a guide rail 1214 arranged along the second direction, and two sliders 1215 slidably connected to the guide rail 1214; the two driving motors 1211 are connected to the two screw rods 1212 in a one-to-one correspondence, the two second clamping arms 122 are connected to the two nuts 1213 in a one-to-one correspondence, and the two second clamping arms 122 are also connected to the two sliders 1215 in a one-to-one correspondence; the two driving motors 1211 are respectively used to drive the screw rods 1212 connected thereto to rotate, so as to move the nuts 1213 on the screw rods 1212, thereby driving the second clamping arms 122 connected to the nuts 1213 to move. In this way, the two second driving members 121 can independently drive the two second clamping arms 122 to move, and can more flexibly control the movement of the two second clamping arms 122. One end of the second clamping arm 122 is connected to the nut 1213 , and the middle portion thereof is connected to the slider 1215 , so that the second clamping arm 122 can be more stable.

[0056] In some embodiments, the second driving member 121 includes a driving motor, a bidirectional screw connected to the driving motor and arranged along the second direction, two nuts 1213 arranged on the bidirectional screw, a guide rail 1214 arranged along the second direction, and two sliders 1215 slidably connected to the guide rail 1214; the two second clamping arms 122 are connected to the two nuts 1213 in a one-to-one correspondence, and the two second clamping arms 122 are also connected to the two sliders 1215 in a one-to-one correspondence; the driving motor 1211 is used to drive the bidirectional screw to rotate, so that the two nuts 1213 move in opposite directions on the bidirectional screw, thereby driving the two second clamping arms 122 to move closer to or farther away from each other. In this way, the second clamping jaw 12 can simultaneously control the two second clamping arms 122 to move closer to or farther away from each other by providing a single driving source.

[0057] It is understandable that the second driving member 121 may also adopt other driving modes, such as cylinder drive, a combination of a motor and a synchronous wheel, a combination of a motor and a gear rack, etc., which are not limited here.

[0058] In some embodiments, as Figure 1 and Figure 2 As shown, the second clamping jaw 12 further includes a floating member 124 and an elastic member 125. The floating member 124 and the elastic member 125 are disposed at one end of at least one second clamping arm 122 away from the second driving member 121. The floating member 124 is located on the side of the second clamping arm 122 facing the second clamping space 123 and is movably connected to the second clamping arm 122. The floating member 124 is movable relative to the second clamping arm 122 in the second direction and is used to clamp the end of the container 4. The elastic member 125 is located between the second clamping arm 122 and the floating member 124, and the elastic member 125 exerts a force on the floating member 124 in the second direction.

[0059] Specifically, by providing a floating member 124 on the second clamping arm 122 and an elastic member 125 between the floating member 124 and the second clamping arm 122, when the second clamping jaw 12 clamps the container 4, the floating member 124 is pressed against the end of the container 4, allowing it to move relative to the second clamping arm 122 in the second direction, while compressing the elastic member 125, thereby allowing the floating member 124 to act as a buffer. The elastic member 125 may be a spring, a spring, a rubber block, or the like.

[0060] like Figure 1 and Figure 2 As shown, the two second clamping arms 122 are each provided with a floating member 124 and an elastic member 125 . When the two second clamping arms 122 clamp the two ends of the container 4 , they can both be buffered and clamped by the floating member 124 .

[0061] In some embodiments, the floating member 124 includes a guide post and a clamping head 1241 disposed on the guide post. The clamping head 1241 is configured to abut against an end of the container 4. The end of the guide post, distal from the clamping head 1241, is movably connected to the second clamping arm 122. The diameter of the clamping head 1241 may be larger than the diameter of the guide post. The guide post is disposed along the second direction and is slidably connected to the second clamping arm 122, enabling it to slide relative to the second clamping arm 122 in the second direction. The guide post guides the floating member 124 as it moves relative to the second clamping arm 122. Specifically, a bearing is fixedly disposed on the second clamping arm 122, and the guide post extends through the bearing and is capable of moving relative to the bearing along its axis.

[0062] In some embodiments, the elastic member 125 is sleeved on the guide post, with one end of the elastic member 125 abutting against the second clamping arm 122, and the other end of the elastic member 125 abutting against the side of the clamping head 1241 away from the second clamping space 123. Optionally, the elastic member 125 is a compression spring or a rubber sleeve.

[0063] In some embodiments, an elastic pad is provided on the side of the clamping head 1241 facing the second clamping space 123. The elastic pad may be a silicone pad, a rubber pad, or the like, which prevents the clamping head 1241 from rigidly contacting the container 4 and protects the container 4. The shape of the clamping surface of the clamping head 1241 in contact with the container 4 is not limited and may be a flat surface, an arc surface, or the like, and may be adapted to the shape of the end of the container 4.

[0064] In some embodiments, as Figure 1 and Figure 2 As shown, the second clamping jaw 12 further includes a position detector 126. The position detector 126 is located on the second clamping arm 122 and is disposed near the floating member 124. The position detector 126 is used to detect the position of the floating member 124 relative to the second clamping arm 122. In other embodiments, the position detector 126 may be located on the floating member 124 and can also be used to detect the position of the floating member 124 relative to the second clamping arm 122.

[0065] Specifically, when the floating member 124 moves to a predetermined position relative to the second clamping arm 122, it triggers the position detector 126. Based on the detection signal from the position detector 126, the second clamping arm 122 is controlled to continue or stop moving in the second direction. For example, when the second clamping jaw 12 clamps the two opposing ends of the container 4, the distance between the two second clamping arms 122 gradually decreases. The floating member 124 moves relative to the second clamping arm 122 in the second direction, compressing the elastic member 125 until the floating member 124 triggers the position detector 126, stopping the movement of the second clamping arm 122. The amount of compression of the elastic member 125 is controlled based on the position detector 126, thereby controlling the pressure exerted by the floating member 124 on the container 4 and ensuring that the clamping force exerted by the second clamping jaw 12 on the container 4 remains at a predetermined value. The position detector 126 may include a photoelectric sensor and a sensor plate, one of which is disposed on the second clamping arm 122 and the other on the floating member 124, to detect the position of the floating member 124 relative to the second clamping arm 122. The position detector 126 may only include a photoelectric sensor, which is used in conjunction with the floating member 124 to detect the relative position of the floating member 124 and the second clamping arm 122. It is understandable that the position detector 126 may also be other structures, such as a distance sensor, which is not limited here.

[0066] In some embodiments, the position detector 126 is located on the second clamping arm 122 and is disposed near the end of the guide post away from the clamping head 1241. The position detector 126 is used to detect the position of the guide post relative to the second clamping arm 122. Exemplarily, the position detector 126 is a photoelectric sensor. When the end of the guide post away from the clamping head 1241 moves relative to the second clamping arm 122 and is sensed by the photoelectric sensor, the second driving member 121 can control the second clamping arm 122 to stop moving.

[0067] By setting up a position detector 126 and using it in conjunction with the elastic member 125, it is possible to ensure that the second clamping jaw 12 clamps both ends of the container 4 and controls the clamping force within a certain range, thereby avoiding damage to the container 4 due to excessive clamping force or affecting the subsequent opening operation of the container 4.

[0068] In some embodiments, the rotation axis of the clamping mechanism 1 is also perpendicular to the first direction, and the first clamping jaw 11 has a first clamping space 113 for accommodating the side wall of the container 4. The rotation axis of the clamping mechanism 1 passes through the center of the first clamping space 113. Specifically, the rotation axis of the clamping mechanism 1 passes through the center of the first clamping space 113. In this way, the first clamping jaw 11 is arranged on the rotation axis of the clamping mechanism 1, and the rotation axis of the clamping mechanism 1 is perpendicular to the opening and closing direction of the first clamping jaw 11, ensuring the stability of the clamping of the first clamping jaw 11.

[0069] In some embodiments, the second clamping jaw 12 has a second clamping space 123 for accommodating the two opposite ends of the container 4, and the center of the second clamping space 123 coincides with the center of the first clamping space 113. In this way, the first clamping jaw 11 is arranged at the center position between the two second clamping arms 122, so that the first clamping jaw 11 can clamp the center part of the container 4, and the clamping is more stable; and the rotation axis of the clamping mechanism 1 passes through the center of the first clamping space 113 and the center of the second clamping space 123, so that the rotation center can be within the container 4, thereby making the rotation more stable and the rotation efficiency higher.

[0070] In some embodiments, as Figures 1 to 3 As shown, the rotating mechanism 2 includes a support base 21, a third driving member 22, a rotating member 23 and a connecting frame 24. The third driving member 22 is arranged on the support base 21. The third driving member 22 is connected to the rotating member 23 and is used to drive the rotating member 23 to rotate. The connecting frame 24 is respectively connected to the rotating member 23 and the clamping mechanism 1.

[0071] Specifically, the rotating member 23 is rotatably connected to the support base 21. The rotating member 23 may be a rotating shaft, which may be rotatably connected to the support base 21 via a bearing. The third driving member 22 drives the rotating member 23 to rotate relative to the support base 21. The rotating member 23 drives the clamping mechanism 1 to rotate via the connecting frame 24. The clamping mechanism 1 drives the container 4 to rotate, thereby turning the container 4.

[0072] The rotation axis of the rotating member 23 is collinear or parallel to the rotation axis of the clamping mechanism 1. When the two are collinear, the turning efficiency of the clamping mechanism 1 is high, thereby improving the mixing efficiency.

[0073] In some embodiments, as Figures 1 to 3 As shown, the rotating mechanism 2 also includes a slip ring 25, which has a stator portion 251 and a rotor portion 252 rotatably connected to the stator portion 251. The stator portion 251 is connected to the support seat 21, and the rotor portion 252 is connected to the rotating member 23; a wire 253 is passed through the slip ring 25, and a first channel 231 is provided in the rotating member 23 for the wire 253 to pass through. After passing through the first channel 231, the wire 253 is electrically connected to the first clamping jaw 11 and / or the second clamping jaw 12.

[0074] Specifically, the rotor portion 252 can rotate synchronously with the rotating member 23, and the stator portion 251 is fixed relative to the support seat 21. For example, the stator portion 251 can be limited by a limiter to be fixed relative to the support seat 21 in the rotation direction of the rotating member 23. When the first drive member 111 and the second drive member 121 are both motors, the wire harness in the wire 253 is electrically connected to the first drive member 111 and the second drive member 121. If one of the first drive member 111 and the second drive member 121 is a motor, the wire harness 253 is electrically connected to the one of the first drive member 111 and the second drive member 121 that is a motor. It is understandable that the wire harness in the wire 253 can also be electrically connected to the position detector 126.

[0075] In some embodiments, the slip ring 25 further comprises an air inlet 254 and an air outlet. The air inlet 254 is located in the stator portion 251, and the air outlet is located in the rotor portion 252. A second passage for gas passage is further provided within the rotating member 23. The second passage is connected to the air outlet and is in communication with the first clamping jaw 11 and / or the second clamping jaw 12. The mixing device further comprises an on-off valve 3 and an air supply device. The on-off valve 3 is in communication with the air inlet 254 and the air supply device, respectively.

[0076] Specifically, when the first drive member 111 and the second drive member 121 are both cylinders, the second channel is connected to the first clamping jaw 11 and the second clamping jaw 12, and the gas supply device supplies gas to the air inlet 254 through the switch valve 3. The gas is transported from the air outlet and the second channel to the first drive member 111 and the second drive member 121, thereby driving the first clamping jaw 11 and the second clamping jaw 12 to open and close. When one of the first drive member 111 and the second drive member 121 is a cylinder, the second channel is connected to the cylinder of the first drive member 111 and the second drive member 121. The switch valve 3 can be a solenoid valve for controlling the on and off of the gas circuit. The gas supply device is used to provide a gas source, such as nitrogen.

[0077] like Figures 1 to 3 As shown, the first driving member 111 is a cylinder, the second driving member 121 is a motor, and the slip ring 25 is a pneumatic slip ring. The wire 253 is electrically connected to the second driving member 121 and the position detector 126, and the second channel is connected to the first driving member 111. The pneumatic slip ring prevents wire entanglement during the rotation of the clamping mechanism 1, which would affect the normal operation and aesthetics of the device.

[0078] In some embodiments, as Figure 1 and Figure 3 As shown, the rotating mechanism 2 further includes a transmission member 26 , which is connected to the third driving member 22 and the rotating member 23 respectively. The third driving member 22 drives the rotating member 23 to rotate through the transmission member 26 .

[0079] In some embodiments, as Figure 3As shown, the transmission member 26 includes a main synchronous wheel 261, a slave synchronous wheel 262 and a synchronous belt 263. The third driving member 22 can be a motor. The main synchronous wheel 261 is fixedly connected to the output shaft of the third driving member 22, the slave synchronous wheel 262 is fixedly connected to the rotating member 23, and the synchronous belt 263 connects the main synchronous wheel 261 and the slave synchronous wheel 262. When the output shaft of the third driving member 22 rotates, the rotating member 23 is driven to rotate through the main synchronous wheel 261, the slave synchronous wheel 262 and the synchronous belt 263.

[0080] In some embodiments, the transmission member 26 includes a main gear and a slave gear, the main gear is fixedly connected to the output shaft of the third driving member 22, the slave gear is fixedly connected to the rotating member 23, and the main gear and the slave gear are meshed.

[0081] In some embodiments, the mixing device further includes a transport mechanism, which is used to place the container 4 on the clamping mechanism 1. The transport mechanism can be a manipulator, a mobile robot, or an XYZ three-axis translation mechanism. During an automated experiment, the transport mechanism can transport the container 4 to be mixed to the clamping mechanism 1 for clamping by the first clamping jaw 11 and the second clamping jaw 12. The transport mechanism can also remove the mixed container 4 from the clamping mechanism 1.
