Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a mixing mechanism and an analytical instrument. Background Technology

[0002] In chemical analysis, the sample composition is becoming increasingly complex, typically encompassing all substances in the gas, liquid, and solid phases. These substances often coexist in a multiphase manner, making direct sampling difficult to accurately reflect the true state of the sample and posing challenges to subsequent measurements. Therefore, before chemical analysis, mixing the sample ensures thorough contact between various components, thereby improving the analytical results.

[0003] In traditional chemical analysis, manual mixing is usually used. This method is not only slow, but also often results in uneven mixing. It is also time-consuming and labor-intensive, making it difficult to meet the high-efficiency requirements of modern chemical analysis.

[0004] Existing chemical analysis instruments are equipped with dedicated mixing mechanisms to improve mixing speed and effectiveness through mechanical mixing. However, these existing mixing mechanisms still have some problems. Their structures are typically large and complex, increasing the overall size and weight of the instrument, as well as manufacturing costs and maintenance difficulties. Furthermore, after picking up the sample, existing mixing mechanisms rotate in a single direction around the sample's central axis. This single mixing trajectory fails to ensure thorough mixing of sample components, thus reducing the overall mixing effect. Utility Model Content

[0019] In one embodiment, one of the first connector and the base is provided with a first slide rail, and the other is provided with a first slide groove that mates with the first slide rail.

[0022] In one embodiment, a connecting rod is provided between the first gripper and the second gripper, one end of the connecting rod being movably connected to the first gripper so that the first gripper can move relative to the second gripper along the connecting rod, the connecting rod being parallel to the extending direction of the first side.

[0040] The mixing mechanism of this utility model places the first driving component of the clamping mechanism on the base and connects the gripper assembly to the first driving component using a connecting component.

[0051] In chemical analysis, the sample composition is becoming increasingly complex, typically encompassing all substances in the gas, liquid, and solid phases. These substances often coexist in a multiphase manner, making direct sampling difficult to accurately reflect the true state of the sample and posing challenges to subsequent measurements. Therefore, before chemical analysis, mixing the sample ensures thorough contact between various components, thereby improving the analytical results.

[0052] In traditional chemical analysis, manual mixing is usually used. This method is not only slow, but also often results in uneven mixing. It is also time-consuming and labor-intensive, making it difficult to meet the high-efficiency requirements of modern chemical analysis.

[0053] Existing chemical analysis instruments are equipped with dedicated mixing mechanisms to improve mixing speed and effectiveness through mechanical mixing. However, these existing mixing mechanisms still have some problems. Their structures are typically large and complex, increasing the overall size and weight of the instrument, as well as manufacturing costs and maintenance difficulties. Furthermore, after picking up the sample, existing mixing mechanisms rotate in a single direction around the sample's central axis. This single mixing trajectory fails to ensure thorough mixing of sample components, thus reducing the overall mixing effect.

[0054] The main purpose of this invention is to provide a mixing mechanism 100 and an analytical instrument, which aims to reduce the volume of the mixing mechanism 100 and improve the mixing effect.

[0055] Please see Figures 1 to 3In one embodiment of this utility model, the mixing mechanism 100 includes: a base 1, a clamping mechanism 2, and a swinging mechanism 3. The clamping mechanism 2 includes a first driving component 21, a gripper assembly 22, and a connecting component 23. The first driving component 21 is disposed on the base 1. One end of the connecting component 23 is connected to the output end of the first driving component 21, and the other end of the connecting component 23 is rotatably connected to the gripper assembly 22. The gripper assembly 22 has a clamping space 223 for clamping materials. The swinging mechanism 3 is disposed on the connecting component 23 and connected to the gripper assembly 22. The first driving component 21 drives the connecting component 23 to cause the gripper assembly 22 to open or close the clamping space 223, and the swinging mechanism 3 drives the gripper assembly 22 to rotate relative to the connecting component 23, thereby causing the materials in the clamping space 223 to swing.

[0056] The mixing mechanism 100 of this utility model places the first driving component 21 of the clamping mechanism 2 on the base 1, and connects the gripper component 22 to the first driving component 21 using the connecting component 23. Thus, the first driving component 21 drives the connecting component 23, thereby causing the gripper component 22 to open or close the clamping space 223, so that the clamping space 223 can clamp materials of different sizes. At the same time, the swinging mechanism 3 is set on the connecting component 23 and connected to the gripper component 22, so that the swinging mechanism 3 directly drives the gripper component 22 to rotate relative to the connecting component 23, realizing the swinging mixing of the material by the gripper component 22. Compared with the single motion mode of rotational mixing, swinging mixing realizes multi-directional motion, thereby improving the mixing effect. Furthermore, while the first driving component 21 drives the gripper component 22 to move, it also drives the swinging mechanism 3 to move accordingly. The swinging mechanism 3 does not need to be connected to the gripper component 22 through a complex transmission component, thus reducing the overall volume and improving the transmission efficiency, making the mixing operation more efficient.

[0057] Please see Figure 2 In one embodiment, the first drive assembly 21 includes a first drive member 211, an auxiliary rod 213, and a first transmission belt 215. The first drive member 211 is disposed on the base 1, and the output end of the first drive member 211 is provided with a first drive wheel 212. The auxiliary rod 213 is disposed on the base 1, and the auxiliary rod 213 is provided with a first driven wheel 214; the first transmission belt 215 is sleeved on the first drive wheel 212 and the first driven wheel 214, and the first transmission belt 215 has opposing first side 2151 and second side 2152, which are respectively connected to the gripper assembly 22 through the connecting assembly 23; wherein, the first drive member 211 drives the first drive wheel 212 to rotate, thereby driving the first transmission belt 215 and the first driven wheel 214 to rotate.

[0058] In this embodiment, the first driving wheel 212 at the output end of the first driving member 211 is connected to the first driven wheel 214 on the auxiliary rod 213 via a first transmission belt 215. The first side 2151 and the second side 2152 of the first transmission belt 215 are respectively connected to the connecting assembly 23, and then to the gripper assembly 22. When the first driving member 211 is activated, it drives the first driving wheel 212 to rotate, causing the first transmission belt 215 and the first driven wheel 214 to rotate, which in turn drives the connecting assembly 23 and the gripper assembly 22 to move, thereby opening or closing the clamping space 223.

[0059] Understandably, the first drive unit 211 provides power and can be a motor, cylinder, or hydraulic cylinder, etc., without limitation. It should be noted that, to facilitate control of the opening size of the clamping space 223 to accommodate materials of different sizes, the first drive unit 211 may be a servo motor or a stepper motor. Alternatively, the first drive unit 211 may be a common AC motor with a reducer at the motor's output to reduce the motor's speed and increase torque, making the movement of the gripper assembly 22 smoother and more precise. Alternatively, the first drive unit 211 may be a cylinder or hydraulic cylinder with a flow valve to improve control accuracy, thereby enabling the clamping space 223 to stably hold the material. These structures are quite common and will not be elaborated upon here.

[0060] In other embodiments, the first drive assembly 21 can also be driven by a lead screw structure, the connecting assembly 23 is movably sleeved on the lead screw and meshes with the lead screw, the first drive member 211 drives the lead screw to rotate, causing the connecting assembly 23 to move along the extension direction of the lead screw, thereby causing the gripper assembly 22 to open or close the clamping space 223.

[0061] Please see Figure 2 In one embodiment, the connecting assembly 23 includes a first connector 231 connected to a first side 2151 and a second connector 232 connected to a second side 2152. The gripper assembly 22 includes a first gripper 221 rotatably connected to the first connector 231 and a second gripper 222 rotatably connected to the second connector 232. The first gripper 221 and the second gripper 222 enclose a clamping space 223. The swing mechanism 3 is connected to the first gripper 221 and the second gripper 222 to drive the first gripper 221 and the second gripper 222 to swing. The first driving member 211 drives the first transmission belt 215 to rotate, causing the first connector 231 and the second connector 232 to move closer or further apart, thus opening or closing the clamping space 223.

[0062] In this embodiment, the first connector 231 and the second connector 232 are respectively connected to the first side 2151 and the second side 2152 of the first transmission belt 215. The first gripper 221 and the second gripper 222 in the gripper assembly 22 are rotatably connected to the first connector 231 and the second connector 232, respectively. When the first drive member 211 drives the first transmission belt 215 to rotate, the first connector 231 and the second connector 232 will move closer to or further away from each other, thereby causing the first gripper 221 and the second gripper 222 to move closer to or further away from each other, realizing the opening and closing of the gripping space 223. The swing mechanism 3 is connected to the first gripper 221 and the second gripper 222, so that the first gripper 221 and the second gripper 222 can reciprocate relative to the first connector 231 and the second connector 232 under the drive of the swing mechanism 3, so as to swing and mix the material.

[0063] Please see Figure 1 In one embodiment, one of the first connector 231 and the base 1 is provided with a first slide rail 121, and the other is provided with a first slide groove (not shown) that mates with the first slide rail 121. The extending direction of the first slide rail 121 is consistent with the moving direction of the first connector 231. Alternatively, one of the second connector 232 and the base 1 is provided with a second slide rail 122, and the other is provided with a second slide groove (not shown) that mates with the second slide rail 122. The extending direction of the second slide rail 122 is consistent with the moving direction of the second connector 232.

[0064] In this embodiment, on the opposite sides of the first connector 231 and the base 1, one is provided with a first slide rail 121, and the other is provided with a first slide groove. The first slide rail 121 and the first slide groove assist the movement of the first connector 231 through the slide rail structure. This not only restricts and guides the movement direction of the first connector 231, causing it to move along the extension direction of the first side 2151, thus ensuring the movement accuracy of the first gripper 221, but also supports the first connector 231, reducing the pressure of the first connector 231 on the first transmission belt 215. It is understood that the first slide rail 121 can be provided either on the side of the base 1 opposite to the first connector 231 or on the side of the first connector 231 opposite to the base 1, and the first slide groove can be provided on the other side. Therefore, the specific positions of the first slide rail 121 and the first slide groove are not specifically limited.

[0065] It is understandable that the second connecting member 232 and the base 1 can also be connected by the second slide rail 122 and the second slide groove with the same structure, so it will not be described in detail here.

[0066] It should be noted that in this embodiment, the first slide rail 121 and the second slide rail 122 are disposed on the base 1 and are aligned along the extension direction of the first side 2151 and connected together. This makes the movable path range of the first connector 231 and the second connector 232 longer, thereby facilitating the adjustment of the clamping position of the first gripper 221 and the second gripper 222.

[0067] Please see Figure 1 In one embodiment, the first connector 231 and the first gripper 221 are rotatably connected by the first pivot 233, and the second connector 232 and the second gripper 222 are rotatably connected by the second pivot 234. The first pivot 233 and the second pivot 234 are collinear and parallel to the extending direction of the first side 2151.

[0068] In this embodiment, the first connecting member 231 has a first through hole (not shown) at one end near the first gripper 221, and the first gripper 221 has a second through hole (not shown) corresponding to the first through hole. A first bearing (not shown) is installed in the first through hole, and a first rotating shaft 233 passes through the first bearing and the second through hole, thereby realizing the rotational connection between the first gripper 221 and the first connecting member 231. Similarly, the second gripper 222 and the second connecting member 232 are rotatably connected through the second rotating shaft 234. This structure is similar to the connection structure between the first gripper 221 and the first connecting member 231, and will not be described in detail here.

[0069] Understandably, the first rotating shaft 233 and the second rotating shaft 234 need to be set collinearly and parallel to the extension direction of the first side 2151, so that the first gripper 221 and the second gripper 222 can maintain good synchronization and stability when rotating.

[0070] In this embodiment, since the structures of the first connector 231 and the second connector 232 are similar, the structure of the first connector 231 will be further described below using the first connector 231 as an example. The first connector 231 includes a connecting portion 2311 connected to the first transmission belt 215, and a supporting portion 2312 connected to the connecting portion 2311. The connecting portion 2311 is L-shaped, with its two sides respectively mounted on the first side 2151 and the supporting portion 2312. The clearance space (not shown) formed by the two sides faces the first transmission belt 215, thus preventing interference with the rotation of the first transmission belt 215. The supporting portion 2312 has a first groove on the side facing the base 1 that mates with the first slide rail 121, and a first through hole at the end of the supporting portion 2312 away from the connecting portion 2311. The supporting portion 2312 is used to support the connecting portion 2311.

[0071] Please refer to Figure 1 and Figure 2In one embodiment, a connecting rod 235 passes between the first gripper 221 and the second gripper 222. One end of the connecting rod 235 is movably connected to the first gripper 221, allowing the first gripper 221 to move relative to the second gripper 222 along the connecting rod 235. The connecting rod 235 is parallel to the extending direction of the first side 2151. A swing mechanism 3 is disposed on the second connecting member 232, and the output end of the swing mechanism 3 is connected to the second gripper 222. The swing mechanism 3 drives the second gripper 222 to swing relative to the second connecting member 232, and drives the first gripper 221 to swing synchronously via the connecting rod 235.

[0072] In this embodiment, a connecting rod 235 is provided between the first gripper 221 and the second gripper 222. One end of the connecting rod 235 is mounted on the second gripper 222, and the other end of the connecting rod 235 is movably connected to the first gripper 221, allowing the first gripper 221 to move relative to the second gripper 222 along the connecting rod 235. Simultaneously, the output end of the swing mechanism 3 is connected to the second gripper 222 via the second rotating shaft 234. It can be understood that the swing mechanism 3 drives the second rotating shaft 234 to rotate, causing the second gripper 222 to swing relative to the second connecting member 232. Then, through the connection of the connecting rod 235, it drives the first gripper 221 to swing synchronously, thereby ensuring that the first gripper 221 and the second gripper 222 swing stably simultaneously after gripping the material, preventing the material from shaking.

[0073] It should be noted that the connecting rod 235 needs to be offset from the second rotating shaft 234 in order to transmit the power of the swing mechanism 3, so that when the second gripper 222 swings, it drives the first gripper 221 to swing synchronously through the connecting rod 235. If the connecting rod 235 is collinear with the second rotating shaft 234, when the second gripper 222 swings around the axis of the second rotating shaft 234, the connecting rod 235 will rotate around its own axis along with the second gripper 222. Since the first gripper 221 is movably connected to the connecting rod 235, the connecting rod 235 will rotate relative to the first gripper 221 and will not be able to drive the first gripper 221 to swing synchronously.

[0074] Please refer to Figure 1 and Figure 2 In one embodiment, the swing mechanism 3 includes a mounting bracket 31, a second driving member 32, and a transmission module 33. The mounting bracket 31 is disposed on the second connecting member 232. The second driving member 32 is disposed on the mounting bracket 31. One end of the transmission module 33 is disposed on the output end of the second driving member 32, and the other end is connected to the second gripper 222. The second driving member 32 drives the transmission module 33 to move, thereby causing the second gripper 222 to rotate, so that the first gripper 221 and the second gripper 222 swing synchronously.

[0075] In this embodiment, the mounting bracket 31 of the swing mechanism 3 is fixed on the second connecting member 232, and the second driving member 32 is mounted on the mounting bracket 31. One end of the transmission module 33 is connected to the output end of the second driving member 32, and the other end is connected to the second gripper 222 through the second rotating shaft 234. It can be understood that the second driving member 32 drives the transmission module 33 to rotate, thereby driving the second gripper 222 to rotate. Through the action of the connecting rod 235, the first gripper 221 swings synchronously.

[0076] Please refer to Figure 2 and Figure 3 In one embodiment, a limiting block 321 is sleeved on the output end of the second driving member 32, and the second driving member 32 drives the limiting block 321 to rotate; a plurality of limiting posts 311 are provided on the side of the mounting bracket 31 facing the limiting block 321, and the limiting posts 311 are used to block the rotation of the limiting block 321 to limit the swing angle of the material.

[0077] In this embodiment, a limiting block 321 is sleeved on the output end of the second driving member 32. When the second driving member 32 drives the limiting block 321 to rotate, the limiting post 311 on the mounting bracket 31 will block the rotation of the limiting block 321, thereby limiting the swing angle of the material. By setting two limiting posts 311, the maximum swing angle of the first gripper 221 and the second gripper 222 can be determined. At the same time, it is also possible to control the first gripper 221 and the second gripper 222 to swing at any angle within the two limiting posts 311 through program control.

[0078] Optionally, the position of one of the limiting posts 311 can be adjusted so that when the limiting block 321 abuts against the limiting post 311, the first gripper 221 and the second gripper 222 swing to an angle perpendicular to the plane where the material is stored, thus facilitating the mixing mechanism 100 to pick up or store the material from the plane.

[0079] Please refer to Figure 1 and Figure 2 In one embodiment, the transmission module 33 includes a second driving wheel 331, a transmission rod 332, a second driven wheel 333, and a second transmission. The second driving wheel 331 is located at the output end of the second driving member 32. The transmission rod 332 is connected to the second gripper 222. The second driven wheel 333 is located on the transmission rod 332. A second transmission belt 334 is sleeved on the second driving wheel 331 and the second driven wheel 333. The second driving member 32 drives the second driving wheel 331 to rotate, thereby causing the second transmission belt 334, the second driven wheel 333, and the transmission rod 332 to rotate, thus causing the second gripper 222 to rotate.

[0080] In this embodiment, the second driving wheel 331 is installed at the output end of the second driving member 32, the transmission rod 332 is connected to the second gripper 222 via the second rotating shaft 234, the second driven wheel 333 is installed on the transmission rod 332, and the second transmission belt 334 is sleeved on the second driving wheel 331 and the second driven wheel 333. It can be understood that the second driving member 32 drives the second driving wheel 331 to rotate, and through the transmission of the second transmission belt 334, drives the second driven wheel 333 and the transmission rod 332 to rotate, thereby causing the second gripper 222 to swing.

[0081] Understandably, the transmission rod 332 and the second rotating shaft 234 can also be integrally formed, with both being the same shaft. This reduces the number of components used and increases the structural strength during rotation.

[0082] Optionally, the transmission module 33 can also drive the second gripper 222 to swing through a gear transmission, worm gear transmission or chain transmission structure. Therefore, the specific structure of the transmission module 33 is not limited.

A clamping mechanism 2 is disposed on the substrate 12. The main support 11 is also provided with a third driving component 13, the output end of which is connected to the substrate 12. The third driving component 13 drives the substrate 12 to move along the main support 11.

[0084] In this embodiment, the base 1 includes a main support 11 and a base plate 12 slidably disposed on the main support 11. The clamping mechanism 2 is mounted on the base plate 12. The main support 11 is also provided with a third driving component 13, and the output end of the third driving component 13 is connected to the base plate 12.

[0085] Understandably, the third drive assembly 13 can drive the substrate 12 to move relative to the plane where the material is stored on the main support 11 to form a first position and a second position. In the first position, the mixing mechanism 100 approaches the plane and picks up or stores material from the plane; in the second position, the mixing mechanism 100 holds the material away from the plane while performing an oscillating mixing operation.

[0086] It should be noted that in this embodiment, the third drive component 13 is driven by a belt drive structure, which is quite common and will not be described in detail here. Alternatively, the third drive component 13 can also drive the base plate 12 to move via a gear drive, worm gear drive, or chain drive structure. Therefore, the specific structure of the third drive component 13 is not limited.

[0087] Please refer to Figure 2 and Figure 3In one embodiment, along the moving direction of the substrate 12, the main support 11 is provided with two limit switches 111, which are used to limit the movement of the substrate 12.

[0088] In this embodiment, two limit switches 111 are provided on the main support 11 along the moving direction of the substrate 12. When the substrate 12 moves to a certain position, the corresponding limit switch 111 is triggered, thereby limiting the movement of the substrate 12. It can be understood that the two limit switches 111 define a first position and a second position.
