In this embodiment, the target 10 is the above-mentioned discrete chip.

Referring to fig. 1, the first connecting assemblies 3 are two and oppositely disposed, the moving assembly 2 includes a first slide rail 21 disposed on the base 1, two first slide blocks 22 disposed on the first slide rail 21, and a first mounting plate 23 disposed on each first slide block 22, and each first mounting plate 23 is provided with one first connecting assembly 3 and one first mounting plate 23.

It is understood that in other embodiments, as shown in fig. 2, one side of the base 1 is provided with the moving component 2a, and the moving component 2a is provided with the first connecting component 3 and the second connecting component 4. The moving assembly 2a may include a first slider 24 and a first mounting plate 25, and the first connecting assembly 3 and the second connecting assembly 4 may be simultaneously located on the first mounting plate 25, so as to achieve the purpose of simultaneously driving the first connecting assembly 3 and the second connecting assembly 4 to be connected with the target 10. It will also be appreciated that in other embodiments, two sets of moving assemblies 2a may be disposed on opposite sides of the target 10, and each set of moving assemblies 2a has the first connecting assembly 3 and the second connecting assembly 4 disposed thereon, so as to drive the two sets of first connecting assemblies 3 and second connecting assemblies 4 to connect the target 10 from opposite sides simultaneously.

Further, the sliding module 31 includes a second sliding rail 311 disposed on the first mounting plate 23, a second sliding block 312 slidably disposed on the second sliding rail 311, and a second mounting plate 313 disposed on the second sliding block 312, the connecting portion 32 is disposed on the second mounting plate 313, and two ends of the elastic member 33 are respectively connected to the first mounting plate 23 and the second mounting plate 313. After 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, so as to drive the second mounting plate 313 to move, the elastic member 33 is compressed, when the driving assembly 5 further drives the first mounting plate 23 to move towards the target body 10, the elastic force of the elastic member 33 pushes the connecting portion 32 to press against the target body 10, so that the connecting portion 32 and the target body 10 are elastically clamped and fixed, rigid connection of the target body 10 is avoided, and the risk of damage of the connecting portion 32 to the target body 10 is reduced in the clamping process.

Further, 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 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 6mm, and the spring hooke's coefficient of the elastic member 33 is 1200N/m, so that the single-side holding force received by the target body 10 is about 3.2N.

Referring to fig. 1 and 4, the multi-component linkage coupling device 100 of the present application is used for coupling and connecting a separation chip of a biological sample processing apparatus, and in addition to clamping and fixing the separation chip, a vibration member is required to provide a vibration wave to the separation chip during a process of separating a biological sample.

It will be appreciated that the structure of the first connection assembly 3a may also be provided on the first mounting plate 23. Referring to fig. 1, the rotation of the driving shaft 52 can drive the two first mounting plates 23 to move towards each other, and further drive the connecting portion 36 to contact with the target 10, the connecting portion 36 is pushed by the reaction force of the target 10 to move towards the direction away from the target 10, and further the elastic member 37 is compressed, the elastic force of the elastic member 37 further pushes the connecting portion 36 to press the target 10, so that the connecting portion 36 is connected with the target 10.

Referring to fig. 1 and 4, the multi-component linkage coupling device 100 of the present application is used for coupling and connecting a separation chip of a biological sample processing apparatus, in a process of separating and processing a biological sample, the separation chip needs to be clamped and fixed, and the separation chip needs to be communicated with a vacuum apparatus through a pipeline, and the separation chip (i.e., a target 10) is communicated with the vacuum apparatus (not shown) through the second connection component 4. The second connecting assembly 4 comprises an adapter portion 41 arranged on the first mounting plate 23 and a communicating pipe 42 with one end connected with the adapter portion 41, the communicating pipe 42 is communicated with a vacuum device through the adapter portion 41, and the driving mechanism 51 is used for driving the driving shaft 52 to rotate so as to drive the adapter portion 41 and the communicating pipe 42 to move, so that one end, far away from the adapter portion 41, of the communicating pipe 42 is communicated with an opening of the target body 10, and the target body 10 is communicated with the vacuum device.

Further, the second connecting assembly 4 further includes an elastic sleeve 43 sleeved on the communication pipe 42. In the process of connecting the target body 10 to the vacuum apparatus, the connection pipe 42 needs to be connected to the opening of the target body 10 in a sealing manner, and therefore, the elastic sleeve 43 is added, so that the opening can be sealed after the connection pipe 42 is connected to the target body 10. In this embodiment, after the elastic sleeve 43 is sleeved on the communication pipe 42, one end of the elastic sleeve 43 is abutted against the side wall of the adapter 41, and the end surface of the other end of the elastic sleeve slightly exceeds the end surface of the communication pipe 42, so that after the communication pipe 42 is communicated with the opening of the target body 10, the elastic sleeve 43 can be compressed to seal the connection position. In this embodiment, the elastic sleeve 43 is made of a flexible material (e.g., 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 tube 43 is determined by the shore hardness of the elastic tube 43 and the driving force of the driving mechanism 51.

Further, two opposite side walls of the separation chip (the target body 10) are provided with openings, and therefore, the number of the second connecting assemblies 4 is two, and the two second connecting assemblies are respectively fixed on the corresponding first mounting plates 23. The driving mechanism 51 is configured to drive the driving shaft 52 to rotate, so as to drive the communicating pipes 42 in the two second connecting assemblies 4 to move in opposite directions to communicate with the target 10. It is understood that the driving assembly 5 can also drive the communicating tubes 42 to move away from the target 10.

Referring to fig. 1 and 5, the multi-component linkage coupling device 100 further includes a displacement sensing component 6, and the displacement sensing component 6 is used for measuring the moving distance of the first connecting component 3 and the second connecting component 4 during the moving process, so as to control the pressure of the connecting portion 32 and the elastic sleeve 43 on the target 10, as described in the foregoing analysis. The displacement sensing assembly 6 includes the first connecting plate 61, a second connecting plate 62 and an optical coupling member 63 disposed on the first connecting plate 61, the first connecting plate 61 and the second connecting plate 62 are respectively fixed on the two first mounting plates 23, and one end of the second connecting plate 62 close to the first connecting plate 61 is slidably connected to the optical coupling member 63. The driving mechanism 51 is further configured to drive the first connecting piece 61 and the second connecting piece 62 to move along the driving shaft 52, and the optical coupler 63 is configured to sense a relative movement distance between the first connecting piece 61 and the second connecting piece 62. In the process that the driving component 5 drives the first connecting component 3 and the second connecting component 4 to be linked, the displacement sensing component 6 senses the moving distance of the two connecting components, so that the connection between the two connecting components and the target body 10 can be better controlled, and the optimal connection effect is realized.

Referring to fig. 1 and fig. 5 again, the multi-component linkage coupling device 100 further includes a limiting member 7 disposed on the base 1. In this embodiment, three limiting members 7 are disposed at specific positions in the extending direction of the driving shaft 52, so as to respectively limit the moving distance of the two first sliding blocks 22, prevent the two first sliding blocks 22 from separating from the first sliding rail 21, and simultaneously prevent the two first sliding blocks 22 from colliding during the moving process.

When the device is used, when a target body 10 needs to be loaded on the biological sample processing device, the driving mechanism 51 drives the driving shaft 52 to rotate in the positive direction, so as to drive the two first sliding blocks 22 to move in the opposite directions, further drive the first connecting assembly 3 and the second connecting assembly 4 on the two first mounting plates 23 to move in the opposite directions, so that the two vibrating pieces 321 clamp and fix the target body 10 from the two opposite side surfaces and transmit vibration waves 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 pieces 33; meanwhile, the two communication pipes 42 are communicated with the two openings of the target body 10, the holding and fixing of the target body 10 and the communication with the vacuum apparatus are realized, and the sealing of the communication pipe 42 and the target body 10 is realized through the elastic sleeve 43. When the target object 10 needs to be unloaded, the driving mechanism 51 drives the driving shaft 52 to rotate reversely, so as to drive the first connecting assembly 3 and the second connecting assembly 4 to be far away from the target object 10, and the unloading of the target object 10 is realized. The application can adjust the ratio or/and the sum of the acting force of the first connecting assembly 3 to the target body 10 in a wide range by selecting the elastic member 33 with different hooke's modulus or/and 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 assembly 3 and the target 10 and the connection between the second connecting assembly 4 and the target 10 may occur simultaneously or may not occur simultaneously, and the connection between the two first connecting assemblies 3 or the connection between the two second connecting assemblies 4 and the target 10 may also occur simultaneously or may not occur simultaneously, specifically according to actual requirements. It is further understood that the functions performed by the first connecting assembly 3 and the second connecting assembly 4 coupled to the target 10 are not limited to the above two functions, and may be specifically designed according to actual needs.
