Referring to fig. 1-3, an embodiment of the present invention provides a cup separating system 100, which is used for separating a cup system 100 from a sampling tube 200, wherein the sampling tube 200 is provided with a cover, so that automatic cover opening and closing can be realized, automatic information recording and automatic liquid transfer can be realized, and the detection efficiency can be improved. Meanwhile, the cover opening, the cover closing, the information checking and the liquid transferring are all automatically completed, and the infection risk in the operation process of an operator is reduced.

It should be noted that the cup dispensing system 100 is not limited to the opening and closing of the cover, information collection, and pipetting of the sampling tube 200 for nucleic acid detection, and can be applied to the opening and closing of the cover, information collection, and pipetting of other detection processes. For convenience of illustration, the opening and closing of the lid, information collection, and pipetting of the sampling tube 200 when the cup dispensing system 100 is applied to nucleic acid detection will be described in detail below, but the description is not intended to limit the scope of the present application.

The cup dispensing system 100 comprises a mounting frame 10, and a clamping device 20, a cap opening device 30 and a pipetting device 40 which are mounted on the mounting frame 10. Specifically, clamping device 20 is fixedly mounted on mounting frame 10 for clamping sampling tube 200. The cap opening device 30 and the pipetting device 40 are movably mounted on the mounting rack 10, and the cap opening device 30 can be controllably moved relative to the mounting rack 10 to move above the clamping device 20 for opening and closing the cap of the sampling tube 200. The pipetting device 40 is controllably moved relative to the mounting frame 10 to move above the clamping device 20 to aspirate a sample in the sampling tube 200 through the pipette tip 50 to complete the pipetting operation.

The mounting rack 10 comprises a bottom plate 11 and a vertical plate 12 which are connected with each other, the clamping device 20 is mounted on the bottom plate 11, and the cover opening device 30 and the liquid transferring device 40 are movably mounted on the vertical plate 12.

Specifically, the cup dispensing system 100 further comprises a sample carrier 60, the sample carrier 60 having a number of receiving holes 61 for placing sampling tubes 200. The uncapping device 30 can grip the sampling tube 200 placed on the sample carrier 60 and transfer the sampling tube 200 onto the clamping device 20, so that the clamping device 20 can clamp the tube body of the sampling tube 200. When the tube body of the sampling tube 200 is clamped by the clamping device 20, the cap-opening device 30 clamps the sampling tube 200 and rotates the cap body of the sampling tube 200, so as to realize the cap-opening operation of the sampling tube 200. When the cover needs to be closed, the tube body of the sampling tube 200 is still clamped by the clamping device 20, and the cover opening device 30 clamps the cover body of the sampling tube 200 and rotates reversely, so that the cover closing operation of the sampling tube 200 is realized.

In one embodiment, referring to fig. 4 and 5, clamping device 20 has a clamping position, and sampling tube 200 is clamped to the clamping position of clamping device 20. Specifically, the clamping device 20 includes an installation seat 21, a clamping assembly 22, a second driving member 23 and a third driving member 24, the installation seat 21 is fixedly installed on the bottom plate 11, and the second driving member 23 and the third driving member 24 are both installed on the installation seat 21. The clamping assembly 22 comprises two clamping blocks 221, wherein one clamping block 221 is connected to the second drive element 23 and the other clamping block 221 is connected to the third drive element 24.

The second driving member 23 and the third driving member 24 are respectively used for driving the two clamping blocks 221 to move towards or away from each other, so that the two clamping blocks 221 clamp the sampling tube 200 from two sides of the sampling tube 200 placed in the clamping position or loosen the sampling tube 200 in the first direction. That is, the second driving member 23 drives one clamping block 221 connected thereto to move, the third driving member 24 drives the other clamping block 221 connected thereto to move, and when the second driving member 23 and the third driving member 24 respectively drive the two clamping blocks 221 to move, the two clamping blocks 221 can clamp the sampling tube 200 located at the clamping position from both sides of the sampling tube 200 in the first direction, or loosen the sampling tube 200 located at the clamping position.

In the clamping device 20, since the second driving member 23 drives one clamping block 221 of the clamping assembly 22 to move, and the third driving member 24 drives the other clamping block 221 of the clamping assembly 22 to move, it is convenient to control the two clamping blocks 221 to simultaneously clamp the sampling tube 200 from both sides of the sampling tube 200 in the first direction. For prior art (one side sets up fixed spacing seat, the opposite side sets up the form of pressing from both sides tight piece, press from both sides tight piece through removing and press from both sides tight sampling tube, such clamping device, when pressing from both sides tight sampling tube, produce eccentric phenomenon or off normal phenomenon easily), but the fixed opposite side in one side is provided with the form of pressing from both sides tight piece 221, has reduced the emergence of eccentric phenomenon and off normal phenomenon, the mouth of pipe of the sampling tube 200 of being convenient for is centered with the liquid-transfering gun head 50 that the device 30 or the liquid-transfering device 40 of uncapping of top loaded, thereby make things convenient for subsequent screw-on lid operation and liquid-transfering operation. Meanwhile, the two clamping blocks 221 of the clamping assembly 22 are driven by the second driving element 23 and the third driving element 24, respectively, so that the two clamping blocks 221 of the clamping assembly 22 can be controlled independently.

Further, referring to fig. 6 and 7, the mounting seat 21 is provided with a placing portion 25 in a protruding manner, and the clamping position is a placing groove 251 opened in the placing portion 25. Further, the clamping device 20 has a housing 260 mounted on the mounting seat 21, the placing portion 25, the second driving member 23, the third driving member 24 and the clamping assembly 22 are all located in the housing 260, an opening 261 is provided on the housing 260, the opening 261 is communicated with the placing groove 251, and the sampling tube 200 is placed in the placing groove 251 through the opening 261. Thus, the housing 260 serves to protect the second drive member 23, the third drive member 24 and the clamping assembly 22.

It should be understood that in other embodiments, the housing 260 may be omitted from the clamping device 20, and is not limited thereto.

In some embodiments, both the second drive member 23 and the third drive member 24 are motors, so as to drive the two clamping blocks 221 of the clamping assembly 22 to simultaneously clamp or unclamp the sampling tube 200. In other embodiments, the types of the second driving member 23 and the third driving member 24 are not limited, and the second driving member 23 and the third driving member 24 may be cylinders.

The sides of the two clamping blocks 221 of clamping assembly 22 facing each other in the first direction each have a clamping opening 2211 for clamping sampling tube 200, such that when the two clamping blocks 221 are moved towards each other to clamp sampling tube 200, at least a portion of sampling tube 200 is received in both clamping openings 2211 to ensure the clamping effect of clamping blocks 221 on sampling tube 200.

Specifically, the cross-sectional shapes of the two clamping ports 2211 are both arc-shaped. And in order to further ensure the clamping effect, clamping teeth are convexly arranged in the clamping port 2211 so as to increase the friction force with the sampling tube 200 and ensure that the sampling tube 200 is clamped.

In one embodiment, the two clamping blocks 221 of the clamping assembly 22 are equidistant from the center of the clamping location. The second driving member 23 and the third driving member 24 are controlled to move synchronously to drive the two clamping blocks 221 of the clamping assembly 22 to synchronously clamp the sampling tube 200. Thus, when the two clamping blocks 221 synchronously clamp the sampling tube 200 from both sides of the sampling tube 200 in the first direction, the occurrence of the eccentricity and the offset is further reduced.

For example, when the clamping position is the placement groove 251, the center of the placement groove 251 in the first direction is equidistant from the two clamping blocks 221, and when the second driving member 23 and the third driving member 24 are controlled to move synchronously, the two clamping blocks 221 of the clamping assembly 22 are ensured to synchronously clamp the sampling tube 200.

It should be noted here that the second driving member 23 and the third driving member 24 are controlled to move synchronously, i.e. the two driving members are of the same kind and move with the same parameters. If the two driving parts are both motors, the two motors are controlled to move for the same number of turns at the same rotating speed.

In an embodiment, the mounting base 21 has a plurality of clamping positions, specifically 4 clamping positions, spaced in the first direction. Specifically, in one embodiment, a plurality of placing portions 25 are protruded from the mounting base 21 in the first direction at intervals, and a placing groove 251 is formed in each placing portion 25 as a clamping position.

The clamping device 20 includes the same number of clamping assemblies 22 as the number of clamping positions, and the clamping assemblies 22 correspond to the clamping positions one by one, that is, a group of clamping assemblies 22 is provided for each clamping position.

Referring to fig. 5, the clamping device 20 further includes two connecting plates 26 extending along a first direction, which are respectively defined as a first connecting plate and a second connecting plate, the first connecting plate is connected to the second driving member 23, and the second connecting plate is connected to the third driving member 24. It is defined that the gripper block of each set of gripper assemblies 22 on one side of sampling tube 200 in the first direction is the first gripper block and the gripper block on the other side of sampling tube 200 in the first direction is the second gripper block. All the first clamping blocks are connected with the first connecting plate, and all the second clamping blocks are connected with the second connecting plate.

The second driving member 23 drives the first connecting plate to reciprocate along the first direction, so as to drive the plurality of first clamping blocks to reciprocate along the first direction. The third driving member 24 drives the second connecting plate to reciprocate along the first direction, so as to drive the plurality of second clamping blocks to reciprocate along the first direction. With such an arrangement, one second driving member 23 can drive a plurality of first clamping blocks to move simultaneously, and one third driving member 24 can drive a plurality of second clamping blocks to move simultaneously, so as to simplify the structure of the clamping device 20 on the premise of ensuring that the clamping device 20 can clamp a plurality of sampling tubes 200 simultaneously.

In one embodiment, the second driving element 23 and the third driving element 24 are disposed at the same end of the mounting base 21 in the first direction to optimize the structural layout of the clamping device 20. Of course, in other embodiments, the second driving element 23 and the third driving element 24 may be disposed at two ends of the mounting seat 21 in the first direction.

Further, the second driving member 23 is provided with a first screw rod extending along the first direction, the first connecting plate is provided with a first nut, and the first screw rod is in threaded connection with the first nut. When the second driving member 23 drives the first screw rod to rotate, the first nut and the first screw rod generate relative motion, and the first connecting plate is driven to move along the first direction. The third driving member 24 is connected with a second screw rod extending along the first direction, the second connecting plate is connected with a second nut, and the second screw rod is in threaded connection with the second nut. When the third driving member 24 drives the second screw rod to rotate, the second nut and the second screw rod generate relative movement, and the second connecting plate is driven to move along the first direction.

It will be appreciated that in other embodiments, the second drive member 23 may also drive the first web via other transmission members, and the third drive member 24 may also drive the second web via other transmission members. Alternatively, in still other embodiments, the transmission may be omitted, with the second drive member 23 driving the first web directly in the first direction and the third drive member 24 driving the second web in the first direction.

Referring to fig. 6, one of the mounting base 21 and the connecting plate 26 is provided with a second guide rail 27 extending along the first direction, and the other is provided with a second sliding block 28, and the second sliding block 28 is in sliding fit with the second guide rail 27. In this way, the second guide rail 27 and the second slide block 28 cooperate to guide the connecting plate 26 (including the first connecting plate and the second connecting plate) so as to control the movement of the clamping block 221 in the first direction.

In one embodiment, the second guide rail 27 is disposed on the mounting base 21, and the second slider 28 is disposed on the connecting plate 26. In another embodiment, the second rail 27 is disposed on the connecting plate 26, and the second slider 28 is disposed on the mounting base 21.

In one embodiment, referring to fig. 5 and 7, the clamping device 20 includes a plurality of connecting blocks 29, and each clamping block 221 is connected to the connecting plate 26 through one connecting block 29, that is, each first clamping block is connected to the first connecting plate through one connecting block 29, and each second clamping block is connected to the second connecting plate through one connecting block 29.

All the connecting blocks 29 are arranged between the first connecting plate and the second connecting plate, and the connecting blocks 29 connected with the first connecting plate and the second connecting plate respectively extend towards the other connecting plate 26, namely each connecting block 29 extends along the third direction.

Referring to fig. 7, the clamping device 20 further includes a plurality of second guide rods 210 and a plurality of second elastic members 240, the second guide rods 210 are respectively disposed through each clamping block 221 and the corresponding connecting block 29, and the second elastic members 240 are disposed between each connecting block 29 and each clamping block 221. One of the connecting block 29 and the clamping block 221 is movable in a first direction relative to the second guide rod 210 penetrating therethrough to compress the second elastic member 240.

With the above arrangement, when the clamping device 20 clamps a plurality of sampling tubes 200, if there is a deviation in the thickness of the sampling tube 200, the thicker sampling tube 200 is first clamped by its corresponding clamping assembly 22, and at this time, in order to clamp the thinner sampling tube 200, the second driving member 23 still drives the first connecting plate to move, and the third driving member 24 also drives the second connecting plate to move. In order to avoid the thicker sampling tube 200 from being damaged by the clamping during the movement of the first and second connection plates, one of the clamping block 221 and the connection block 29 mounted on the second guide rod 210 can be moved relative to the second guide rod 210, so that the clamping block 221 mounted on the first and second connection plates moves relative to the second guide rod, thereby avoiding the thicker sampling tube 200 from being damaged by the clamping. While the second resilient member 240 is compressed when one of the connecting block 29 and the clamping block 221 moves relative to the second guide bar 210 threaded therethrough, the second resilient member 240 repositions the clamping block 221 or the connecting block 29, which moves relative to the second guide bar 210, when the clamping assembly 22 releases the sampling tube 200.

The second elastic member 240 may be a spring, so as to be sleeved outside the second guide rod 210, or other types of second elastic members 240, such as an elastic sleeve made of rubber.

Further, each clamping block 221 is correspondingly provided with a plurality of second guide rods 210, specifically two. That is, two second guide rods 210 are arranged through each clamping block 221 and the corresponding connecting block 29, a second elastic member 240 is sleeved outside each second guide rod 210, and two second elastic members 240 are arranged between each clamping block 221 and each connecting block 29. The above arrangement ensures the guiding and resetting effects.

The second guide rod 210 includes a second rod 220 and a third limiting portion 230, the second rod 220 penetrates the connecting block 29, the second elastic member 240 and the clamping block 221, and the third limiting portion 230 is disposed at an end of the second rod 220 penetrating through the connecting block 29. The second rod 220 is fixedly connected to the clamping block 221, and the connecting block 29 is movably disposed between the second elastic member 240 and the third position-limiting portion 230. Thus, when the clamping device 20 clamps a plurality of sampling tubes 200, if there is a deviation in the thickness of the sampling tube 200, the thicker sampling tube 200 is first clamped by its corresponding clamping assembly 22, and at this time, in order to clamp the thinner sampling tube 200, the second driving member 23 still drives the first connecting plate to move, and the third driving member 24 also drives the second connecting plate to move. During the movement of the first and second connection plates, the clamping block 221 of the clamping assembly 22 clamping the thicker sampling tube 200 will not move due to the restriction of the sampling tube 200, and the connection plate 26 corresponding thereto moves relative to the second rod 220 to compress the second elastic member 240, thereby ensuring that the thinner sampling tube 200 is also clamped. When the clamping assembly 22 releases the sampling tube 200, the third stopper 230 prevents the connecting plate 26 from separating from the second rod 220.

In one embodiment, the clamping device 20 further includes an electro-optical switch 250 disposed on the mounting seat 21 for resetting the first connecting plate and the second connecting plate.

In an embodiment, referring to fig. 8 and 9, the lid opening device 30 includes a fixed seat 31, a movable seat 32, and a lid opening mechanism 33, wherein the fixed seat 31 is movably mounted on the vertical plate 12, the movable seat 32 is movably mounted on the fixed seat 31 in the second direction, and the lid opening mechanism 33 is mounted on the movable seat 32.

The first direction, the second direction and the third direction are vertical to each other. The first direction is a Y direction in fig. 1, the second direction is a Z direction in fig. 1, and the third direction is an X direction in fig. 1.

When the sampling tube 200 needs to be transferred, the fixed seat 31 drives the movable seat 32 and the uncovering mechanism 33 to move relative to the mounting rack 10, and when the sampling tube is moved to above the sample carrier 60, the movable seat 32 drives the uncovering mechanism 33 to move downwards relative to the fixed seat 31 in a second direction so as to clamp the sampling tube 200. Then, the cover opening mechanism 33 moves upward in the second direction to return to the original position, and the fixed seat 31 carries the movable seat 32 and the cover opening mechanism 33 to move again relative to the mounting seat 21 to move above the clamping device 20. The cover opening mechanism 33 moves downwards relative to the fixing seat 31 in the second direction to place the sampling tube 200 in the clamping position, the clamping block 221 clamps the tube body of the sampling tube 200, and the cover opening mechanism 33 drives the cover body of the sampling tube 200 to rotate relative to the clamped tube body, so that the cover opening of the sampling tube 200 is realized. At this time, the fixed seat 31 drives the movable seat 32 and the cover opening mechanism 33 holding the cover to move away, the liquid-transferring device 40 is controlled to move to the upper side of the clamping device 20, and the liquid-transferring gun head 50 loaded on the liquid-transferring device 40 extends into the tube body to take liquid. After the liquid is taken by the liquid-transferring device 40, the cap-opening device 30 moves to the upper part of the clamping device 20 again, and the cap-opening mechanism 33 screws the cap body onto the tube body in the opposite direction, so as to close the cap of the sampling tube 200.

After the liquid is taken out by the liquid-transferring device 40, the liquid-transferring device 40 is controlled to move to above the deep well plate 80, and the sample solution taken out from the tube is discharged to the deep well plate 80. Meanwhile, the cup separating system 100 further comprises a waste pipette tip collecting box 90, and the pipette tips 50 after liquid taking are thrown into the waste pipette tip collecting box 90 for collection.

In one embodiment, referring to fig. 9, the cap-opening device 30 includes a plurality of cap-opening mechanisms 33, the plurality of cap-opening mechanisms 33 are sequentially mounted on the movable base 32 in a first direction, the movable base 32 is controlled to drive all the cap-opening mechanisms 33 to reciprocate relative to the fixed base 31 in a second direction, and one cap-opening mechanism 33 is used for opening and closing the cap of one sampling tube 200. Specifically, the plurality of cap opening mechanisms 33 are located on the same side of the movable seat 32, and the number of the cap opening mechanisms 33 is equal to the number of the clamping positions of the clamping device 20, so that the cap opening device 30 can simultaneously open and close the plurality of sampling tubes 200 when the clamping device 20 clamps the plurality of sampling tubes 200.

In one embodiment, the clamping device 20 is provided with four clamping positions at intervals in the first direction, and the cap-opening device 30 is provided with four cap-opening mechanisms 33 in the first direction.
