Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0056] It should be noted that, in the absence of conflict, the features in the embodiments of the present disclosure may be combined with each other.

[0057] As mentioned in the background art, in traditional sample analyzers, sample containers need to be manually installed to complete sampling, and the sampling operation and the shaking operation are not continuous, resulting in low overall sample shaking efficiency, which in turn limits the working efficiency of the sample analyzer.

[0058] Please refer to Figures 1 to 17. The shaking device 100, shaking method, sample injection method, sample unloading method and sample analyzer provided in the embodiments of the present disclosure can solve the above problems, which will be described in detail below.

[0059] 1 to 6 , the shaking device 100 includes a base 110 , a driving member 120 , a driving wheel assembly 130 , a driven wheel assembly 140 , and a clamping member 150 ;

[0060] The driving member 120 is provided on the base 110, and the clamping member 150 is configured to clamp the sample container 190; the driving wheel assembly 130 includes a first turntable 131 and a rocker 132, the first turntable 131 is connected to the driving member 120 by transmission, one end of the rocker 132 is connected to the first turntable 131 by rotation, and the other end of the rocker 132 is connected to the clamping member 150 by rotation; the driven wheel assembly 140 includes a second turntable 141 and a guide rail 142, the second turntable 1 41 is movably arranged on the base 110, the guide rail 142 is arranged on the second turntable 141, and the clamping member 150 is engaged with and slidably cooperates with the guide rail 142; the driving member 120 is configured to drive the first turntable 131 to rotate, so that the rocker 132 drives the clamping member 150 to slide along the guide rail 142, and after the clamping member 150 reaches the extreme position of the guide rail 142, the second turntable 141 is driven to rotate synchronously through the guide rail 142 to shake the sample in the sample container 190.

[0061] When the shaking device 100 is in use, the driving member 120 can provide power to drive the first turntable 131 to rotate, so that the rocker arm 132 drives the clamping member 150 to slide along the guide rail 142. When the clamping member 150 slides to one end of the guide rail 142, the sample container 190 can be loaded into the clamping member 150; then the driving member 120 drives the first turntable 131 to rotate in the opposite direction, so that when the clamping member 150 moves to the other end of the guide rail 142, the second turntable 141 can be driven to rotate by the cooperation of the clamping member 150 and the guide rail 142. Through the synchronous rotation of the first turntable 131 and the second turntable 141, the sample in the sample container 190 clamped by the clamping member 150 can be shaken, and it is ensured that the injection operation and the shaking operation are more consistent, thereby ensuring the shaking efficiency of the sample and avoiding limiting the working efficiency of the sample analyzer.

[0062] It is worth noting that the guide rail 142 has two ends and the driving member 120 also has two rotation directions. When the driving member 120 rotates in the first direction, it can drive the first turntable 131 to rotate in the first direction, and drive the clamping member 150 to slide to the first end of the guide rail 142 through the rocker 132. At this end, the sample container 190 is usually loaded or unloaded. When the driving member 120 rotates in the second direction, it can drive the first turntable 131 to rotate in the second direction, and drive the clamping member 150 to slide to the second end of the guide rail 142 through the rocker 132, and form a sliding limit at this end. When the driving member 120 continues to rotate, the clamping member 150 is clamped at the second end of the guide rail 142 and no longer slides. At the same time, through the clamping connection between the clamping member 150 and the guide rail 142, the driving member 120 continues to rotate, which can drive the second turntable 141 supporting the guide rail 142 to start rotating, thereby realizing the synchronous rotation of the clamping member 150 and the sample container 190, thereby shaking the sample in the sample container 190.

[0063] It is worth noting that, referring to FIG1 , the first direction and the second direction are both rotational directions, and the rocker arm converts the rotational motion into the linear motion of the sample container.

[0064] 2 , the drive member 120 includes a drive motor 121, a driving pulley 122, a driven pulley 123, and a timing belt 124. The drive motor 121 is configured to provide a power source, and its output shaft is connected to the driving pulley 122. The driving pulley 122 then transmits power to the driven pulley 123 via the timing belt 124. The driven pulley 123 is in transmission connection with the first rotary disk 131. Furthermore, the drive member 120 includes a tensioning pulley 125, which is mounted on the base 110 and configured to tension the timing belt 124.

[0065] Optionally, a first screw hole is opened in the axial center of the tensioning wheel 125, and a waist hole is opened on the plate surface of the base 110 at the position corresponding to the tensioning wheel 125. The first screw hole is connected to a locking screw 126, and the locking screw 126 is configured to lock and position the base 110 and the tensioning wheel 125.

[0066] A second threaded hole is provided on the side of the base 110 at a position corresponding to the waist hole. The second threaded hole is connected to the waist hole and is connected to an adjustment screw 127. One end of the adjustment screw 127 is located in the waist hole and engages with the tensioning pulley 125. Before the locking screw 126 locks the tensioning pulley 125 and the base 110, the adjusting screw 127 can be rotated to adjust the axial position of the adjusting screw 127 relative to the second threaded hole, thereby adjusting the relative position of the tensioning pulley 125 and the base 110, thereby adjusting the tightness of the synchronous belt 124. After the position is determined, the tensioning pulley 125 is fixed by the locking screw 126.

[0067] Referring to Figure 4, the driving wheel assembly 130 also includes a central rotating shaft 133, a threaded bearing and a locking nut. The two ends of the central rotating shaft 133 are respectively connected to the driven pulley 123 and the first turntable 131. The end of the rocker arm 132 is connected to the first turntable 131 through a threaded bearing and is locked by a locking nut to achieve relative rotational movement between the rocker arm 132 and the first turntable 131.

[0068] 3 , 7 and 8 , the clamping member 150 includes a clamping seat 151 and a clamping block 152 connected to each other. The clamping seat 151 is slidably engaged with the guide rail 142 . A clamping cavity 153 is formed between the clamping block 152 and the clamping seat 151 . The clamping cavity 153 is configured to accommodate a sample container 190 .

[0069] Optionally, in order to improve the convenience of replacing the clamp seat 151 , a slider 144 may be provided on the guide rail 142 , and the clamp seat 151 is mounted on the slider 144 , so as to achieve sliding fit with the guide rail 142 through the slider 144 .

[0070] It is worth noting that there are multiple guide rails 142, which are equidistantly spaced along the axial direction of the second turntable 141. The extension direction of each guide rail 142 is consistent with the radial direction of the second turntable 141. The first end of the guide rail 142 refers to the end of the guide rail 142 near the edge of the second turntable 141, and the second end of the guide rail 142 refers to the end of the guide rail 142 near the center of the second turntable 141. In addition, each guide rail 142 is correspondingly provided with a clamping member 150 and a rocker arm 132.

[0071] In this embodiment, there are six guide rails 142, and correspondingly, six groups of clamping members 150 and rocking arms 132. This means that six sample containers 190 can be simultaneously loaded and shaken. To prevent interference between the six rocking arms 132 during swinging, the six rocking arms 132 are divided into three groups, each group comprising two rocking arms 132. The corresponding clamping members 150 and guide rails 142 of the rocking arms 132 in the same group are positioned opposite each other. One group of rocker arms 132 can be located on a side of the first turntable 131 close to the second turntable 141, and two groups of rocker arms 132 can be located on a side of the first turntable 131 away from the second turntable 141. The two groups of rocker arms 132 located on the same side have different axial positions on the first turntable 131, so that when the rocker arms 132 drive the clamping member 150 to move to the second end of the guide rail 142, the multiple rocker arms 132 can be staggered with each other, which can prevent the center of mass of the sample container 190 from being too far away from the center of the first turntable 131, thereby helping to reduce the space occupied by the entire device.

[0072] Referring to Figures 8 and 9, the clamping member 150 also includes a guide rod 154, a limit block 155 and a spring 156. The limit block 155 is located on the side of the clamping seat 151 away from the clamping block 152. The guide rod 154 passes through the clamping seat 151 and its two ends are respectively connected to the clamping block 152 and the limit block 155. The spring 156 is sleeved on the guide rod 154 and is located between the clamping seat 151 and the limit block 155. The guide rail 142 is arranged between the limit block 155 and the clamping seat 151.

[0073] Furthermore, when the side of the limiting block 155 away from the clamping seat 151 is displaced by the resisting force, the spring 156 can be compressed, and the guide rod 154 can be used to drive the clamping block 152 away from the clamping seat 151, so that the clamping cavity 153 becomes larger, making it easier to unload the sample container 190 in the clamping cavity 153. When the limiting block 155 is not displaced by other external forces, the tension of the spring 156 can ensure a sufficient distance between the limiting block 155 and the clamping seat 151, so that the clamping block 152 can maintain an appropriate distance from the clamping seat 151 under the pulling action of the guide rod 154, so that the size of the clamping cavity 153 is exactly matched with the sample container 190, thereby preventing the sample container 190 from falling out of the clamping cavity 153 during the shaking process.

[0074] 7 , 10 and 11 , the shaking device 100 further includes a damper 160 . The damper 160 is mounted on the base 110 and cooperates with the second turntable 141 .

[0075] Optionally, the driven wheel assembly 140 also includes a driven gear 143, which is transmission-connected to the second turntable 141. The damper 160 includes a damping gear 161 and a damping plate 162 that are transmission-connected. The damping gear 161 and the damping plate 162 are respectively located on both sides of the base 110, and the damping gear 161 is meshed with the driven gear 143.

[0076] In the above technical solution, the damping gear 161 transmits the rotational motion of the second turntable 141 to the damping disc 162 by meshing with the driven gear 143. The damping disc 162 can provide rotational resistance to the driven gear 143 and the second turntable 141, which helps to eliminate the inertia and vibration generated by the rotational motion of the second turntable 141.

[0077] It is worth noting that the damping disc 162 contains liquid with high friction and strong flow resistance, so that the damping disc 162 can generate resistance when rotating.

[0078] In addition, at least three support bearings 115 are provided on the base 110 along the axial direction of the second turntable 141 . The support bearings 115 are in contact with the second turntable 141 and are configured to balance the second turntable 141 .

[0079] In this embodiment, there are three support bearings 115 , which are symmetrically arranged along the center of the second turntable 141 , that is, a central angle formed by two adjacent support bearings 115 and the center of the second turntable 141 is 120°.

[0080] 10 and 13 , the shaking device 100 further includes a sample injection support 170 , which is mounted on the base 110 . A sample injection slide 171 is formed on the sample injection support 170 , and the clamping member 150 is in sliding engagement with the sample injection slide 171 .

[0081] Optionally, the extending direction of the sample injection support 170 is consistent with the radial direction of the second turntable 141. In addition, both ends of the sample injection slide 171 are open, and one end is tapered to facilitate the guide function when the limit block 155 enters the sample injection slide 171.

[0082] In the above technical solution, when the sample container 190 needs to be installed, the driving member 120 can be reversed when it rotates to a suitable position along the second direction, and starts to rotate along the first direction, driving the first turntable 131 to rotate, while the second turntable 141 stops rotating, thereby driving the rocker arm 132 to swing, so that the clamping member 150 moves toward the first end of the guide rail 142. Before reaching the first end of the guide rail 142, the limit block 155 on the clamping member 150 can be locked into the sample injection slide 171, further ensuring that the clamping member 150 avoids shaking during the injection process, helping to improve the injection stability and facilitating the sample container 190 to be loaded into the clamping cavity 153.

[0083] It is worth noting that the shaking device 100 further includes a sensor configured to output information representing the circumferential position of the clamping member 150. Optionally, the circumferential position of the clamping member 150 refers to the relative position of the same clamping member 150 and the center of the second turntable 141 during the process of synchronous rotation with the second turntable 141.

[0084] 16 , an embodiment of the present disclosure further provides a sample injection method, which is implemented based on the shaking device 100 having the sample injection support 170 . The sample injection method includes:

[0085] S310: Control the driving member 120 to drive the first rotary disk 131 to rotate in the first direction, and drive the clamping member 150 to slide along the guide rail 142 through the rocker 132;

[0086] S320: Control the clamping member 150 to cooperate with the sample injection slide 171;

[0087] S330 : Control the sample container 190 to be loaded into the clamping member 150 .

[0088] 10 and 14 , the shaking device 100 further includes a tube unloading support 180 , which is mounted on the base 110 . A tube unloading slide 181 is formed on the tube unloading support 180 . The clamping member 150 slides in cooperation with the tube unloading slide 181 , and a portion of the bottom wall of the tube unloading slide 181 is tilted.

[0089] Optionally, the extension direction of the pipe unloading support 180 is consistent with the radial direction of the second rotary disk 141. In addition, one end of the pipe unloading slide 181 is open and tapered, which facilitates the guidance of the limit block 155 when it enters the pipe unloading slide 181; the other end of the pipe unloading slide 181 is closed to prevent the limit block 155 from sliding out of the pipe unloading slide 181 and leaving the guide rail 142.

[0090] In the above technical solution, when the sample container 190 needs to be removed, the driving member 120 can be reversed when it rotates to a suitable position along the second direction, and starts to rotate along the first direction, driving the first turntable 131 to rotate, while the second turntable 141 stops rotating, thereby driving the rocker arm 132 to swing, so that the clamping member 150 moves toward the first end of the guide rail 142. Before reaching the first end of the guide rail 142, the limit block 155 on the clamping member 150 can be stuck in the sample unloading slide, further ensuring that the clamping member 150 does not shake during the sample unloading process.

[0091] It is worth noting that, when the base 110 is vertically arranged, by arranging the tube unloading support 180 near the bottom of the base 110 and allowing the tube unloading slide 181 to extend from top to bottom, combined with the inclined bottom of the tube unloading slide 181 and its bottom wall tilting from top to bottom away from the base 110, the limit block 155 will move toward the clamping seat 151 during the sliding process, thereby compressing the spring 156 and driving the clamping block 152 away from the clamping seat 151 via the guide rod 154, so that the clamping cavity 153 is opened, and the sample container 190 located in the clamping cavity 153 can naturally fall out of the clamping cavity 153 under the action of gravity, thereby completing the tube unloading operation.

[0092] 17 , an embodiment of the present disclosure further provides a sample unloading method, which is implemented based on the shaking device 100 having the tube unloading support 180 . The sample unloading method includes:

[0093] S410: Control the driving member 120 to drive the first rotating disk 131 to rotate in the first direction, and drive the clamping member 150 to move along the guide rail 142 through the rocker 132;

[0094] S420: Control the clamping member 150 to cooperate with the pipe unloading slide 181;

[0095] S430 : Control the clamping member 150 to contact the inclined bottom wall of the tube unloading slide 181 to release the sample container 190 .

[0096] In addition, in order to ensure that the clamping member 150 can smoothly cooperate with the sample injection support 170 and the tube unloading support 180, the sensor and the driving member 120 can communicate, and the sensor can be used to detect the circumferential rotation position of the clamping member 150 so that the driving member 120 can reverse at the appropriate time, thereby ensuring that the limit block 155 can be smoothly inserted into the sample injection slide 171 or the tube unloading slide 181.

[0097] Alternatively, the sensor may be an optical coupler identifier 118 that uses light signals to identify each clamping member 150. Alternatively, the second turntable 141 may have multiple through holes, and the optical coupler identifier 118 may be mounted on the base 110. The light signals may pass through the through holes, while the second turntable 141 may block the light signals and determine the position of the clamping member 150 on the guide rail 142 based on the positions of the through holes.

[0098] Moreover, because the driving member 120 is reversed when rotating in the second direction during the injection or tube unloading operations to drive the first turntable 131 to rotate in the first direction, the specific reversal time point of the driving member 120 (corresponding to the circumferential position of each clamping member 150 when the driving member 120 is reversed) can be determined in combination with the optical coupling identifier 118 to ensure that the clamping member 150 can smoothly cooperate with the injection support 170 when injection is required, and can smoothly cooperate with the tube unloading support 180 when tube unloading is required.

[0099] Of course, the positions of the sample injection support 170 and the tube unloading support 180 can be flexibly set so that during the overall operation, when the driving member 120 reverses and drives the first turntable 131 to rotate along the first direction, it can drive one of the clamping members 150 to cooperate with the sample injection support 170, and at the same time drive the other clamping member 150 to cooperate with the tube unloading support 180, thereby allowing the sample injection operation and the tube unloading operation to be carried out simultaneously.

[0100] 15 , an embodiment of the present disclosure further provides a shaking method, which is implemented based on the above-mentioned shaking device 100 and includes:

[0101] S210: Control the driving member 120 to drive the first rotating disk 131 to rotate in the first direction, and drive the clamping member 150 to slide to one end of the guide rail 142 through the swing rod 132;

[0102] Furthermore, before the sample container 190 is loaded, the clamping member 150 will cooperate with the injection support 170 during the sliding process, and the limit block 155 will be locked into the injection slide 171 to ensure that the clamping member 150 will not shake during the injection process.

[0103] S220: Control the sample container 190 to be loaded into the clamping member 150;

[0104] It is worth noting that due to the tension of the spring 156, the gap between the clamping block 152 and the clamping seat 151 is slightly smaller than the outer diameter of the sample container 190. During the loading process of the sample container 190, force is applied to the sample container 190 in the loading direction so that the bottom of the sample container 190 can be correspondingly engaged with the clamping cavity 153.

[0105] S230: Control the driving member 120 to drive the first rotary disk 131 to rotate in the second direction, and drive the clamping member 150 to slide to the other end of the guide rail 142 through the swing rod 132;

[0106] S240 : The second rotating disk 141 and the first rotating disk 131 are driven to rotate synchronously along the second direction by the clamping member 150 being clamped on the guide rail 142 , so as to shake the sample in the sample container 190 .

[0107] The shaking method further includes step S250: controlling the driving member 120 to drive the first rotating disk 131 to rotate in a first direction, and driving the clamping member 150 to slide to one end of the guide rail 142 via the swing rod 132;

[0108] During the sliding process, the clamping member 150 engages with the tube unloading support 180, and the stopper 155 engages the tube unloading slide 181, ensuring that the clamping member 150 does not shake during the tube unloading process. Furthermore, the stopper hole can be guided by the inclined bottom wall of the tube unloading slide 181 and move toward the clamping seat 151, thereby compressing the spring 156 and driving the clamping block 152 away from the clamping seat 151 via the guide rod 154, thereby opening the clamping cavity 153. The sample container 190 located in the clamping cavity 153 can naturally fall out of the clamping cavity 153 under the action of gravity, thus completing the tube unloading operation.

[0109] An embodiment of the present disclosure also provides a sample analyzer, including the above-mentioned shaking device 100, as well as a sample injection device, a tube unloading device and a detection sensor. The sample injection device can use a manipulator to place the sample container 190 to be shaken into the clamping cavity 153 on the sample injection support 170, and the tube unloading device is configured to receive the sample container 190 that falls off the clamping cavity 153 on the tube unloading support 180.

[0110] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims. Industrial Applicability

[0111] By adopting the above solution, operations such as injection, shaking, and tube unloading of the sample container can be realized through one drive. While ensuring the stable operation of the shaking device, the injection and shaking operations are more consistent, ensuring the shaking efficiency of the sample, flexible structure, and space saving.
