The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0059] See also Figure 1 In one embodiment of the present application, a multi-component linkage coupling device 100 is provided. The multi-component linkage coupling device 100 is used in a biological sample separation device to couple with a target body (which may be a separation chip in the present application). The coupling connection here includes but is not limited to abutment, lamination, and communication. Among them, abutment and lamination can achieve a variety of functions, such as providing a clamping force for the target body, providing a vibration wave for the target body, etc. The multi-component linkage coupling device 100 includes a base 1, a mobile component 2, at least one first connection component 3 and at least one second connection component 4 arranged on the mobile component 2, and a driving component 5. The driving component 5 includes a driving mechanism 51 arranged on the base 1, and a driving shaft 52 arranged at the output end of the driving mechanism 51, and the mobile component 2 is arranged on the driving shaft 52. The driving mechanism 51 is used to drive the driving shaft 52 to rotate, so as to drive the mobile component 2 to move along the driving shaft 52, and then drive each of the first connection components 3 and each of the second connection components 4 to move toward the target body 10 to connect with the target body 10. In this embodiment, the target body 10 is the above-mentioned separation chip.

[0060] See also Figure 1 , the first connecting components 3 are two oppositely arranged, the moving component 2 includes a first slide rail 21 arranged on the base 1, two first sliders 22 arranged on the first slide rail 21, and a first mounting plate 23 arranged on each of the first sliders 22, and each of the first mounting plates 23 is provided with a first connecting component 3 and a first mounting plate 23. The driving mechanism 51 can drive the driving shaft 52 to rotate, thereby driving the two first mounting plates 23 and the first connecting components 3 thereon to move toward or away from each other, so as to connect or release the target body 10.

[0061] It can be understood that in other embodiments, such as Figure 2As shown, a moving component 2a is provided on one side of the base 1, and the first connecting component 3 and the second connecting component 4 are provided on the moving component 2a at the same time. The moving component 2a may include a first slider 24 and a first mounting plate 25, and the first connecting component 3 and the second connecting component 4 may be located on the first mounting plate 25 at the same time, so as to achieve the purpose of simultaneously driving the first connecting component 3 and the second connecting component 4 to connect with the target body 10. It can also be understood that in other embodiments, two groups of moving components 2a may be provided on opposite sides of the target body 10, and the first connecting component 3 and the second connecting component 4 are provided on each group of moving components 2a, so as to achieve the purpose of simultaneously driving the two groups of first connecting components 3 and the second connecting components 4 to connect with the target body 10 from opposite sides.

[0062] See also Figure 1 In the present application, the two first connecting components 3 on the moving component 2 are used to clamp and fix the target body 10 from opposite sides of the target body 10, which can reduce unnecessary positioning mechanisms and simplify the equipment structure.

[0063] The first connection assembly 3 includes a sliding module 31 disposed on the first mounting plate 23, a connecting portion 32 disposed on the sliding module 31, and an elastic member 33. The two ends of the elastic member 33 are respectively disposed on the first mounting plate 23 and the sliding module 31. The driving mechanism 51 is used to drive the driving shaft 52 to rotate, drive the connecting portion 32 to contact the target body 10, and the connecting portion 32 drives the sliding module 31 to move along the driving shaft 52 in a direction away from the target body 10 under the action of the reaction force of the target body 10 to compress the elastic member 33, and the elastic restoring force of the elastic member 33 is used to push the connecting portion 32 to resist the target body 10.

[0064] Further, the sliding module 31 includes a second slide rail 311 disposed on the first mounting plate 23, a second slider 312 slidably disposed on the second slide rail 311, and a second mounting plate 313 disposed on the second slider 312. The connecting portion 32 is disposed on the second mounting plate 313, and the two ends of the elastic member 33 are respectively connected to the first mounting plate 23 and the second mounting plate 313. When the connecting portion 32 contacts the target body 10, the connecting portion 32 is forced to move in a direction away from the target body 10, thereby driving the second mounting plate 313 to move, and the elastic member 33 is compressed. When the driving assembly 5 further drives the first mounting plate 23 to move toward the target body 10, the elastic force of the elastic member 33 will push the connecting portion 32 to press the target body 10, so as to realize the elastic clamping and fixing of the connecting portion 32 and the target body 10, avoid the rigid connection to the target body 10, and reduce the risk of damage to the target body 10 by the connecting portion 32 during the clamping process.

[0065] Furthermore, the elastic member 33 is a spring, and the clamping force of the connecting portion 32 on the target body 10 is controlled by adjusting the Hooke's elastic coefficient of the elastic member 33 and the distance of the connecting portion 32 moving toward each other. In this embodiment, the distance of the two connecting portions 32 moving toward each other is about 6 mm, and the Hooke's coefficient of the elastic member 33 is 1200 N / m, so the unilateral clamping force received by the target body 10 is about 3.2 N.

[0066] See also Figure 1 and Figure 4 The multi-component linkage coupling device 100 of the present application is used for coupling connection of separation chips of biological sample processing equipment. In the process of separation and processing of biological samples, in addition to clamping and fixing the separation chip, it is also necessary to provide vibration waves for the separation chip through a vibrator. The present application realizes providing vibration waves for the target body 10 through a first connection component 3. Specifically, the connecting portion 32 includes a vibrator 321, one end of which is fixed on the second mounting plate 313, and the other end can abut against the surface of the target body 10 and transmit the vibration waves to the target body 10. The vibration wave can be transmitted to the target body 10 by the vibration component 321 on the first connection component 3 being in contact with the target body 10. The driving mechanism 51 is used to drive the driving shaft 52 to rotate, thereby driving the vibration component 321 to move, so that the vibration component 321 is in contact with the surface of the target body 10 to transmit the vibration wave to the target body 10.

[0067] Understandable, see Figure 3 In other embodiments, the first connecting component 3a includes a guide rod 34 fixed on the first mounting plate 25, a second slider 35 slidably mounted on the guide rod 34, a connecting portion 36 disposed on the second slider 35, and an elastic member 37 mounted on the guide rod 34. One end of the elastic member 37 abuts against the side wall of the second slider 35, and the other end abuts against the side wall of the first mounting plate 25. It can be understood that the structure of the first connecting component 3a can also be set on the first mounting plate 23. Figure 1 The rotation of the driving shaft 52 can drive the two first mounting plates 23 to move toward each other, thereby driving the connecting part 36 to contact the target body 10. Under the action of the reaction force of the target body 10, the connecting part 36 is pushed to move away from the target body 10, thereby compressing the elastic member 37. The elastic force of the elastic member 37 further pushes the connecting part 36 to press the target body 10, thereby realizing the connection between the connecting part 36 and the target body 10.

[0068] See also Figure 1 and Figure 4The multi-component linkage coupling device 100 of the present application is used for coupling and connecting the separation chip of the biological sample processing equipment. In the process of separation and processing of the biological sample, in addition to clamping and fixing the separation chip, it is also necessary to connect the separation chip with the vacuum equipment through a pipeline. The present application connects the separation chip (i.e., the target body 10) with the vacuum equipment (not shown) through the second connection component 4. The second connection component 4 includes an adapter 41 provided on the first mounting plate 23 and a connecting pipe 42 connected to the adapter 41 at one end. The connecting pipe 42 is connected to the vacuum equipment through the adapter 41. The driving mechanism 51 is used to drive the driving shaft 52 to rotate, thereby driving the adapter 41 and the connecting pipe 42 to move, so that the end of the connecting pipe 42 away from the adapter 41 is connected to the opening of the target body 10, thereby connecting the target body 10 with the vacuum equipment.

[0069] Furthermore, the second connection assembly 4 also includes an elastic sleeve 43 sleeved on the connecting tube 42. In the process of connecting the target body 10 with the vacuum device, the connecting tube 42 needs to be sealed with the opening of the target body 10. Therefore, by adding the elastic sleeve 43, the sealing of the opening can be achieved after the connecting tube 42 is connected with the target body 10. In this embodiment, after the elastic sleeve 43 is sleeved on the connecting tube 42, one end abuts against the side wall of the adapter 41, and the end face of the other end slightly exceeds the end face of the connecting tube 42. Therefore, after the connecting tube 42 is connected with the opening of the target body 10, under the action of pressure, the elastic sleeve 43 can be compressed to seal the connection. In this embodiment, the material of the elastic sleeve 43 is a variable soft material (such as rubber), and the compression amount of the elastic sleeve 43 can be adjusted to achieve a sealing effect. The specific compression amount of the elastic sleeve 43 is determined by the Shore hardness of the elastic sleeve 43 and the driving force of the driving mechanism 51.

[0070] Further, the two opposite side walls of the separation chip (target body 10) are provided with openings, therefore, the number of the second connection components 4 is two, which are respectively fixed on the corresponding first mounting plate 23. The driving mechanism 51 is used to drive the driving shaft 52 to rotate, thereby driving the connecting pipes 42 in the two second connection components 4 to move toward each other to connect the target body 10. It can be understood that the driving component 5 can also drive the two connecting pipes 42 to move away from each other to separate from the target body 10.

[0071] See also Figure 1 and Figure 5The multi-component linkage coupling device 100 also includes a displacement sensing component 6, which is used to measure the moving distance of the first connecting component 3 and the second connecting component 4 during the movement process, and then control the pressure of the connecting part 32 and the elastic sleeve 43 on the target body 10, see the above analysis. The displacement sensing component 6 includes the first connecting piece 61, the second connecting piece 62 and the optical coupling 63 arranged on the first connecting piece 61, the first connecting piece 61 and the second connecting piece 62 are respectively fixed on the two first mounting plates 23, and the second connecting piece 62 is slidably connected to the optical coupling 63 at one end close to the first connecting piece 61. The driving mechanism 51 is also used to drive the first connecting piece 61 and the second connecting piece 62 to move along the driving shaft 52, and the optical coupling 63 is used to sense the relative moving distance of the first connecting piece 61 and the second connecting piece 62. In the process of the driving component 5 driving the first connecting component 3 and the second connecting component 4 to be linked, by setting the displacement sensing component 6 to sense the moving distance of the two connecting components, the connection between the two connecting components and the target body 10 can be better controlled to achieve the best connection effect.

[0072] Please refer again Figure 1 and Figure 5 The multi-component linkage coupling device 100 further includes a stopper 7 disposed on the base 1. In this embodiment, three stoppers 7 are disposed at specific positions in the extension direction of the drive shaft 52, which can respectively limit the moving distance of the two first sliders 22, thereby preventing the two first sliders 22 from being separated from the first slide rail 21, and also preventing the two first sliders 22 from colliding during the movement.

[0073] During use, when it is necessary to load the target body 10 on the biological sample processing device, the driving mechanism 51 drives the driving shaft 52 to rotate in the forward direction, driving the two first sliders 22 to move toward each other, and then driving the first connecting components 3 and the second connecting components 4 on the two first mounting plates 23 to move toward each other, so that the two vibrating members 321 clamp and fix the target body 10 from two opposite sides and transmit the vibration wave to the target body 10, wherein the clamping force on the target body 10 is the sum of the elastic forces of the two elastic members 33; at the same time, the two connecting pipes 42 are connected with the two openings of the target body 10, so as to achieve the clamping and fixing of the target body 10 and the connection with the vacuum device, and the sealing of the connecting pipe 42 and the target body 10 is achieved through the elastic sleeve 43. When it is necessary to unload the target body 10, the driving mechanism 51 drives the driving shaft 52 to rotate in the reverse direction, thereby driving the first connecting component 3 and the second connecting component 4 away from the target body 10, so as to achieve the unloading of the target body 10. The present application can adjust the force ratio and / or the sum of the first connecting component 3 acting on the target body 10 in a wide range by selecting elastic members 33 with different Hooke's coefficients and / or adjusting the compression amount of the elastic member 33; the loading and unloading of the first connecting component 3 and the second connecting component 4 can be adjusted by adjusting the displacement of the moving component 2. It can be understood that the connection between the first connecting component 3 and the second connecting component 4 and the target body 10 can occur simultaneously or at different times, and the connection between the two first connecting components 3 or the two second connecting components 4 and the target body 10 can also occur simultaneously or at different times, which is specifically set according to actual needs. It can also be understood that the functions realized after the first connecting component 3 and the second connecting component 4 are coupled and connected to the target body 10 are not limited to the above two functions, and can also be specifically designed according to actual needs.

[0074] Compared with the prior art, the multi-component linkage coupling device 100 provided in the present application can drive the linkage of the first connection component 3 and the second connection component 4 through a driving component 5 combined with a moving component 2, thereby realizing the connection between the first connection component 3 and the second connection component 4 and the target body 10. The first connection component 3 and the second connection component 4 do not need to be driven independently, which reduces the structural complexity of the multi-component linkage coupling device 100, reduces the volume of the multi-component linkage coupling device 100, and reduces the cost; the linkage process is simple to operate and has low control difficulty. In addition, the first connection component 3 and the second connection component 4 can realize various functions after being coupled with the target body 10, and can adapt to more application scenarios.
