It will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
A reagent card selecting system shown in fig. 1 comprises a reagent card storage device 1, a reagent card picking device 2, a reagent card transferring device 3 and a reagent card adjusting device 4;
the reagent card storage device 1 can sequentially arrange a plurality of reagent cards along a preset track line, and the reagent cards arranged on the reagent card storage device 1 are provided with a first state position and a second state position;
the reagent card picking device 2 can move the reagent card on the reagent card storage device 1 from the first state position to the second state position according to a preset reagent card picking scheme;

As shown in fig. 1 and 2, the reagent card storage device 1 includes a card rack 11, the top end of the card rack 11 is sequentially provided with a plurality of first accommodating cavities 11a along a preset path line, the first accommodating cavities 11a extend along a vertical direction and are slidably connected with the reagent cards, and the reagent cards in the second state position on the card rack 11 are higher than the reagent cards in the first state position, so that the reagent cards in the first state position on the card rack 11 cannot be contacted with the reagent card transfer device 3 in the process that the reagent card transfer device 3 moves from the reagent card storage device 1 to the reagent card adjusting device 4 along the preset path line, and the reagent cards in the second state position on the card rack 11 can be clamped by the reagent card transfer device 3.
Preferably, an inverted V-shaped first elastic member 12 is disposed in the first accommodating cavity 11a, one end of the first elastic member 12 is integrally connected with a side wall of the first accommodating cavity 11a, and a supporting portion 121 is formed at the other end of the first elastic member 12;
when the reagent card in any first accommodating cavity 11a is in the first state position, the supporting part 121 of the first elastic piece 12 in the first accommodating cavity 11a is abutted with the side part of the reagent card;
when the reagent card in any first accommodating cavity 11a is in the second state position, the supporting part 121 of the first elastic member 12 in the first accommodating cavity 11a is abutted with the bottom end of the reagent card, so as to support the bottom end of the reagent card and keep the reagent card in the second state position.
As shown in fig. 1 and 3, the reagent card picking apparatus 2 includes a reagent card lifting mechanism disposed below the card holder 11, and a first horizontal moving mechanism 51 capable of driving the reagent card lifting mechanism to move along a predetermined trajectory.
Preferably, the reagent card lifting mechanism comprises a first linear actuator 21 and a lifting member 22 in driving connection with the first linear actuator 21. As an example, the first linear actuator 21 is an electromagnet. The first linear actuating member 21 is arranged in the vertical direction, and when the first linear actuating member 21 is in the contracted state, the jacking member 22 is positioned below the clamping frame 11; when the first linear actuator 21 is in the extended state, the lifting member 22 can extend into any of the first accommodating chambers 11a, so as to lift up the reagent card in the first accommodating chamber 11a, and move the reagent card in the first accommodating chamber 11a from the first state position to the second state position. When the reagent card in the first accommodating cavity 11a is in the second state, the supporting portion 121 of the first elastic member 12 in the first accommodating cavity 11a abuts against the bottom end of the reagent card, so as to support the bottom end of the reagent card. The first resilient member 12 still keeps the reagent card in the second state position when the subsequent first linear actuator 21 is restored to the contracted state.
As shown in fig. 1 and 4, the reagent card transporting apparatus 3 comprises a reagent card gripping mechanism and a second horizontal movement mechanism 52 capable of driving the reagent card gripping mechanism to move along a predetermined trajectory.
Preferably, the reagent card clamping mechanism comprises a mounting seat 31, a supporting plate 32 and a feeding plate 33 which extend along a preset track line are arranged on the left side and the right side below the mounting seat 31, a plurality of first tooth-shaped parts 321 are uniformly distributed on the top end of the supporting plate 32 along the length direction of the supporting plate, a plurality of second tooth-shaped parts 331 are uniformly distributed on the top end of the feeding plate 33 along the length direction of the feeding plate, and the top point of the first tooth-shaped parts 321 is staggered with the bottom point of the first tooth-shaped parts 321 in the vertical direction;
the support plate 32 is connected with a turnover assembly 36, the turnover assembly 36 can drive the support plate 32 on the left side and the right side and the feed plate 33 to be close to or separated from each other, the feed plate 33 is connected with a lifting assembly 37, and the lifting assembly 37 can drive the feed plate 33 to do lifting reciprocating motion along the side wall of the support plate 32. As an example, the side wall of the support plate 32 is connected with a sliding block 322, the feeding plate 33 is provided with a sliding rail 332 extending along the vertical direction and slidingly connected with the sliding block 322, and the feeding plate 33 can reciprocate up and down along the side wall of the support plate 32 under the coordination of the sliding block 322 and the sliding rail 332.
The bottom end of the mounting seat 31 is connected with a pressing seat 34 extending along a preset track line through a second elastic member 35. As an example, as shown in fig. 4, a slide bar 341 extending in a vertical direction is connected to a top end of the pressing seat 34, a slide hole slidably connected to the slide bar 341 is formed in the mounting seat 31, and the pressing seat 34 can perform lifting and reciprocating movement under the coordination action of the slide bar 341 and the slide hole.
For ease of understanding, as shown in fig. 7, the reagent card 6 includes a plate body, the side portion of the top end of which is formed with a tooth-shaped gripping portion 61, and the end of the feed plate 33 near the reagent card adjusting device 4 is longer than the carrier plate 32, respectively.
Specifically, the operation mechanism of the reagent card clamping mechanism of this embodiment is:
as shown in fig. 8, in the initial state, the left and right support plates 32 and the feed plate 33 are in a state of being close to each other, the second tooth-shaped portions 331 of the feed plate 33 are lower than the first tooth-shaped portions 321 of the support plates 32, the second horizontal moving mechanism 52 first moves the reagent card gripping mechanism to position it to the reagent card in the second state, and the portion of the feed plate 33 longer than the support plate 32 is positioned below the gripping portions 61 of the reagent card 6. Then, the lifting assembly 37 drives the feeding plate 33 to lift along the side wall of the supporting plate 32, so that the clamping portion 61 of the reagent card 6 is engaged with the second tooth-shaped portion 331 on the feeding plate 33, the reagent card lifts along the feeding plate 33 and abuts against the pressing seat 34, and at this time, the second elastic member 35 connected to the pressing seat 34 has a tendency to drive the pressing seat 34 to move downward due to being pressed. Next, after the oblique edge of the second tooth-shaped portion 331 is aligned with the oblique edge of the adjacent first tooth-shaped portion 321, the pressing seat 34 drives the reagent card to slide down along the oblique edge of the adjacent first tooth-shaped portion 321 under the action of the second elastic member 35, so that the clamping portion 61 of the reagent card 6 slides into the first tooth-shaped portion 321. Then, the lifting assembly 37 drives the feeding plate 33 to descend along the side wall of the supporting plate 32, so that the pressing seat 34 drives the reagent card to slide down along the inclined edge of the first tooth-shaped portion 321 until the clamping portion 61 of the reagent card 6 is engaged with the first tooth-shaped portion 321.
After the second horizontal moving mechanism 52 drives the reagent card clamping mechanism with the reagent card clamped thereon to move above the reagent card adjusting device 4, the overturning assembly 36 drives the left and right support plates 32 and the feeding plate 33 to separate from each other until the support plates 32 and the feeding plate 33 get rid of the reagent card, so that the pressing seat 34 drives the reagent card to move downward under the action of the second elastic member 35, and the reagent card is transferred to the reagent card adjusting device 4. In addition, in order to prevent the reagent card from deviating during the process of the pressing seat 34 driving the reagent card to move downward, as shown in fig. 5, a guiding wall 342 is formed at the bottom end of the pressing seat 34 and engaged with the reagent card.
It will be appreciated that, as shown in fig. 9, if a reagent card is already placed on any first tooth 321 and is engaged with the first tooth 321, when the lifting assembly 37 drives the feeding plate 33 to make a lifting and reciprocating motion along the side wall of the supporting plate 32, the reagent card on the first tooth 321 enters the following first tooth 321 along the declining direction of the hypotenuse of the first tooth 321. Thus, the reagent card gripping mechanism of the present embodiment can sequentially arrange the gripped reagent cards on the carrier plate 32.
As another example, the bottom end of the mounting seat 31 is not provided with the second elastic member 35 and the pressing seat 34, so that when the oblique edge of the second tooth-shaped portion 331 is aligned with the oblique edge of the adjacent first tooth-shaped portion 321, the reagent card slides into the adjacent first tooth-shaped portion 321 from the second tooth-shaped portion 331 under the action of gravity; and when the carrier plate 32 and the feeding plate 33 get rid of the reagent card, the reagent card falls into the reagent card adjusting device 4 under the action of self gravity. However, it should be noted that, because the reagent card of this example is light in weight, the reagent card is not considered as an optimal solution in this specification because it is easy to get stuck during the process of sliding from the second tooth-shaped portion 331 into the adjacent first tooth-shaped portion 321 and during the process of falling into the reagent adjusting apparatus.
Preferably, the turnover assembly 36 includes a second linear actuator 361 and a swing arm 362 hinged to the mounting seat 31, the second linear actuator 361 is drivingly connected to a first lifting seat 363, the first lifting seat 363 is provided with an elongated guide hole 363a, one end of the swing arm 362 is integrally connected to the support plate 32, and the other end of the swing arm 362 is provided with a pin 3621 slidably connected to the guide hole 363 a. As one example, the second linear actuator 361 is an electromagnet. The second linear actuator 361 is disposed in the vertical direction, and when the second linear actuator 361 is in the extended state, the swing arms 362 on the left and right sides of the mount 31 each drive the carrier plate 32 and the feed plate 33 connected thereto to separate from each other; when the second linear actuator 361 is in the contracted state, the swing arms 362 on the left and right sides of the mount 31 each drive the support plate 32 and the feed plate 33 connected thereto to approach each other.
Preferably, the lifting assembly 37 comprises a third linear actuating member 371 and a flexible transmission member, wherein the third linear actuating member 371 is in transmission connection with a second lifting seat, and the transmission member is integrally connected with the feeding plate 33 and the second lifting seat respectively. As an example, the transmission member is made of shape memory metal and the third linear actuator 371 is an electromagnet. The third actuating member is disposed in a vertical direction, and when the third linear actuating member 371 is in an elongated state, the first tooth-shaped portion 321 of the carrier plate 32 is lower than the second tooth-shaped portion 331 of the feed plate 33; when the third linear actuator 371 is in the contracted state, the first tooth 321 of the carrier plate 32 is higher than the second tooth 331 of the feed plate 33.
As shown in fig. 6, the reagent card adjusting device 4 includes a plurality of parallel holders 41, and a plurality of third horizontal moving mechanisms 53 connected with each holder 41 one by one, wherein the top end of the holder 41 is provided with a second accommodating cavity 41a, the second accommodating cavity 41a extends along a vertical direction and is slidably connected with the reagent card, and the third horizontal moving mechanisms 53 can drive the holders 41 connected with the third horizontal moving mechanisms to do horizontal reciprocating motion along a vertical direction of a preset track line.

First, according to a preset reagent card picking scheme, the first horizontal moving mechanism 51 drives the reagent card lifting mechanism to sequentially reach the lower parts of the first accommodating cavities 11a where the first reagent card, the second reagent card and the third reagent card are located, and the first linear actuating member 21 of the reagent card lifting mechanism drives the lifting member 22 to sequentially extend into the first accommodating cavities 11a, so as to lift the first reagent card, the second reagent card and the third reagent card, so that the first reagent card, the second reagent card and the third reagent card are moved from the first state position to the second state position, and the first reagent card, the second reagent card and the third reagent card are all kept at the second state position under the action of the first elastic member 12 connected with the first accommodating cavities 11 a.
Then, the second horizontal moving mechanism 52 drives the reagent card clamping mechanism to sequentially move to the first, second and third reagent cards, so that the reagent card clamping mechanism sequentially clamps the first, second and third reagent cards.
Next, the second horizontal moving mechanism 52 drives the reagent card clamping mechanism to move above the reagent card adjusting device 4, and makes the first, second and third reagent cards on the reagent card clamping mechanism align with the second accommodating cavities 41a on the 3 card holders 41 of the reagent card adjusting device 4 one by one.
Subsequently, the overturning assembly 36 of the reagent card clamping mechanism drives the left and right support plates 32 and the feeding plate 33 to separate from each other until the support plates 32 and the feeding plate 33 are both free of the reagent card, so that the pressing seat 34 drives the reagent card to move downwards under the action of the second elastic piece 35, and the first, second and third reagent cards are respectively sent into the aligned second accommodating cavities 41a.
Then, the third horizontal moving mechanism 53 is in transmission connection with the first, second and third reagent card holders 41 according to a preset reagent card arrangement scheme, and drives the first, second and third reagent card holders 41 to move along the vertical direction of the preset track line, so that the first, second and third reagent card holders are positioned on the same straight line, and synchronous sample injection can be performed on the first, second and third reagent card holders at the subsequent time, thereby improving the sample adding efficiency.
