[0043] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0045] It should be noted that if Figures 1 to 9 As shown, the card insertion device 10 is mainly used in a fluorescent immunoassay analyzer 100 to insert and fix a reagent card 50, wherein the reagent card 50 can be a single card, a double card, a triple card or other multi-cards, and no particular limitation is made here. Figure 8 and Fig. 9 As shown, the reagent card 50 can be in a rectangular parallelepiped structure, wherein the side of the reagent card 50 can be provided with a groove 51, and the back of the reagent card 50 can be provided with a positioning groove 52, etc.; Of course, the shape and structure of the reagent card 50 are not limited to the above description, and other suitable deformation structures can be applied, and no special restrictions are made here. Of course, in other embodiments, the card insertion device 10 can also be used to insert and fix other card parts, and no special restrictions are made here.

[0046] The present invention provides a card insertion device 10, such as Figures 2 to 9 As shown, the card insertion device 10 includes a body 1 , a pushing member 2 and a driving device 3 .

[0047] The main body 1 is provided with a first slot 11 for inserting a card; it should be noted that, in the present embodiment, a card such as a reagent card 50 is inserted into the first slot 11, wherein the reagent card 50 may be a single-link card, a two-link card, a triple-link card or other multi-link cards, and the width of the first slot 11 is wider than the width of the card such as the reagent card 50 to support the reagent card 50 to be inserted into the first slot 11 at will, wherein the reagent card 50 is approximately a rectangular structure, that is, the width of the first slot 11 corresponds to the shorter end of the reagent card 50, and the length of the first slot 11 corresponds to the longer end of the reagent card 50.

[0048] The output end of the driving device 3 is connected to the pusher 2. The driving device 3 drives the pusher 2 to move along the width direction of the first slot 11 into or out of the first slot 11. When the pusher 2 is extended into the first slot 11, it abuts against the card. Figure 7 As shown, the front end of the body 1 close to the operator has a slot entrance 111, which is convenient for the card to be inserted into the first slot 11 from the slot entrance 111. The right side of the body 1 has a channel connected to the first slot 11, and the bottom of the body 1 corresponding to the first slot 11 has a positioning slot 52, etc. It can be understood that the driving device 3 drives the pusher 2 to move in the first slot 11 along the width direction of the first slot 11, so that the pusher 2 can adjust the position of the pusher 2 in the first slot 11 according to the width of the card inserted into the first slot 11, so that the slot wall of the first slot 11 away from the pusher 2 and the pusher 2 jointly clamp the card so that the card is firmly fixed in the first slot 11. Specifically in this embodiment, the pusher 2 and the driving device 3 are integrated on the body 1 to improve the compactness of the structure of the card insertion device 10, wherein the slot wall of the body 1 corresponding to the first slot 11 is provided with the above-mentioned channel extending along the width direction of the first slot 11 and connected to the first slot 11, and the pusher 2 moves along the channel to extend into the first slot 11 or extend out of the first slot 11.

[0049] It can be understood that the working principle of the card insertion device 10 is as follows: insert the card into the first slot 11 of the body 1; according to the position of the card in the first slot 11, control the driving device 3 to drive the pusher 2 to extend into the first slot 11 along the width direction of the first slot 11 to abut against the card, so that the slot wall of the first slot 11 away from the pusher 2 and the pusher 2 jointly clamp the card so that the card is firmly fixed in the first slot 11. When the card needs to be taken out, the driving device 3 drives the pusher 2 in the opposite direction to extend out of the first slot 11 along the width direction of the first slot 11 to disengage from the card, and at this time the card is out of the clamping state and can be quickly taken out.

[0050] In summary, the card insertion device 10 drives the pusher 2 to move into or out of the first slot 11 along the width direction of the first slot 11 through the drive device 3, so as to be able to adjust the position of the pusher 2 in the first slot 11 according to the width of the card inserted into the first slot 11, such as the reagent card 50, so that the slot wall of the first slot 11 away from the pusher 2 and the pusher 2 jointly clamp the reagent card 50 so that the reagent card 50 is firmly fixed in the first slot 11. Therefore, the first slot 11 of the card insertion device 10 can adapt to reagent cards 50 of different widths, and supports the reagent card 50 to be inserted into the first slot 11 at will and positioned and firmly clamped, without the need to accurately insert the first slot 11, and without the need to equip different types of brackets to firmly clamp the reagent card 50, and can simultaneously load and remove multiple cards, with the characteristics of simple structure and simple and convenient operation.

[0051] In some embodiments, Figures 4 to 9As shown, the pusher 2 is provided with a first matching piece, and the first matching piece is used to adapt to the second matching piece of the card member. When the pusher 2 is movably extended into the first slot 11 along the width direction of the first slot 11, the pusher 2 can cooperate with the second matching piece of the card member through the first matching piece to adjust the position of the card member inserted into the first slot 11. It can be understood that when the card member, such as the reagent card 50, is randomly inserted into the first slot 11 and is not in an accurate position relative to the first slot 11, such as when it is tilted, when the pusher 2 is driven by the driving device 3 to extend into the first slot 11, the reagent card 50 can adjust its position steadily under the drive of the pusher 2 through the cooperation of the first matching piece and the second matching piece, so that the reagent card 50 is accurately inserted into the first slot 11, effectively avoiding the displacement of the reagent card 50 relative to the first slot 11, which affects the subsequent detection operation. Therefore, by setting a first matching piece on the pushing piece 2 to cooperate with the second matching piece of the card piece, the first slot 11 can adapt to reagent cards 50 of different widths under the action of the pushing piece 2, and at the same time, the position of the reagent card 50 can be adjusted so that the reagent card 50 can be accurately installed in the first slot 11. The user can insert the reagent card 50 at will, further improving the user experience and the convenience and speed of card insertion.

[0052] In some embodiments, the pusher 2 is provided with a protrusion 21 adapted to the groove 51 of the card, and the protrusion 21 is a first matching member; or, the pusher 2 is provided with a groove 51 adapted to the protrusion 21 of the card, and the groove 51 is a first matching member. It can be understood that, specifically in this embodiment, Figure 5 and Figure 8 As shown, the first end of the pushing member 2 is connected to the output end of the driving device 3, and the end of the second end is provided with a protrusion 21. The card component such as the reagent card 50 is provided with a groove 51 on the side close to the pushing member 2. The protrusion 21 of the pushing member 2 is adapted to the groove 51 provided on the side close to the pushing member 2 of the reagent card 50, so that the protrusion 21 can contact the groove 51 of the reagent card 50 when the pushing member 2 is extended into the first slot 11, so that the protrusion 21 and the groove 51 can adjust the offset position of the reagent card 50 during the adaptation and fitting process.

[0053] Of course, in another embodiment, similarly, a groove 51 may be provided at the end of the pusher 2, and a protrusion 21 matching the groove 51 is provided on the side of the reagent card 50 close to the pusher 2, so that the offset position of the reagent card 50 can be adjusted during the fitting process between the groove 51 and the protrusion 21.

[0054] In some embodiments, Figure 5 and Figure 8As shown, the pusher 2 is provided with a protrusion 21, the protrusion 21 is triangular, and the two inclined surfaces of the protrusion 21 are respectively matched with the groove 51 of the card to form an inclined contact; or, the pusher 2 is provided with a groove 51, the groove type of the groove 51 is triangular, and the two inclined surfaces of the groove 51 are respectively matched with the protrusion 21 of the card to form an inclined contact. It can be understood that the triangular protrusion 21 and the groove 51 of the triangular groove are matched to form an inclined contact through two inclined surfaces, which can increase the contact area between the protrusion 21 and the groove 51 on the one hand, and the inclined surface can guide the movement between the reagent card 50 and the pusher 2 on the other hand, so that the reagent card 50 can slide to the final matching point of the protrusion 21 and the groove 51 under the action of the inclined surface, thereby effectively adjusting the offset position of the reagent card 50. Of course, in other embodiments, the protrusion 21 and the groove 51 can also be other suitable shapes such as trapezoids, etc., which are not particularly limited here.

[0055] In some embodiments, Figure 2 and Figure 8 As shown, the main body 1 is further provided with a positioning member 22 corresponding to the first slot 11, and the positioning member 22 is used to fit the positioning groove 52 of the card; or, the main body 1 is further provided with a positioning groove 52 corresponding to the first slot 11, and the positioning groove 52 is used to fit the positioning member 22 of the card. It can be understood that, specifically in this embodiment, the main body 1 is provided with a positioning member 22 at the bottom of the slot corresponding to the first slot 11, and the back of the reagent card 50 is provided with a positioning groove 52. When the reagent card 50 is inserted into the first slot 11 and pushed to the correct position of the first slot 11 by the pusher 2, the positioning member 22 of the main body 1 is stuck in the positioning groove 52 on the back of the reagent card 50. On the one hand, it can form a positioning function, so that the reagent card 50 can be accurately inserted into the preset position of the first slot 11, and on the other hand, it can form a sense of touch to the user, thereby improving the user experience. Of course, in another embodiment, similarly, the body 1 is provided with a positioning groove 52 at the bottom of the groove corresponding to the first slot 11, and at this time, the back of the reagent card 50 is provided with a positioning piece 22. When the reagent card 50 is pushed to the correct position of the first slot 11 by the pushing piece 2, the positioning piece 22 on the back of the reagent card 50 is inserted into the positioning groove 52 of the body 1. It should be noted that the positioning piece 22 can be a positioning marble, and the positioning groove 52 is an arc groove adapted to the positioning marble. The contact surface of the positioning marble and the arc-shaped positioning groove 52 can enable the positioning marble to accurately and smoothly slide into the positioning groove 52, and can slide out of the positioning groove 52 under the action of external force, and has a good mechanical touch.

[0056] In some embodiments, Figure 3As shown, the card insertion device 10 further includes a sliding pair 4, the sliding pair 4 includes a slide rail 41 and a sliding member 42, the slide rail 41 is arranged on the body 1 along the width extension direction of the first slot 11, the pusher 2 is arranged on the sliding member 42, and the sliding member 42 is slidably arranged in the slide rail 41. It can be understood that through the sliding cooperation between the slide rail 41 and the sliding member 42, the pusher 2 can be smoothly reciprocated along the direction of the slide rail 41 to smoothly push the reagent card 50.

[0057] In some embodiments, the driving device 3 may be a screw drive motor, which can drive the pusher 2 to move linearly along the width extension direction of the first slot 11, and has the characteristics of high precision, high efficiency, and low friction. Of course, in other embodiments, the driving device 3 may also be a linear motor, etc., which is not particularly limited here.

[0058] In some embodiments, Figure 3 As shown, at the position between the driving device 3 and the pushing member 2, the body 1 and the pushing member 2 are connected by a buffer 5. It can be understood that the buffer 5 is used to form a buffering effect on the pushing member 2, so that when the pushing member 2 is driven by the driving device 3 and extends into the first slot 11, it is buffered by the buffer 5, reducing the impact force of the pushing member 2 on the card, avoiding damage to the card, and can increase the service life of the driving device 3. Specifically in this embodiment, the buffer 5 can be a component with elasticity such as a compression spring, which has low cost and good elasticity, so as to form an effective buffer for the pushing member 2; of course, in other embodiments, the buffer 5 can also be other components with buffering properties such as a foam layer or a rubber member, and no special limitation is made here.

[0059] In some embodiments, Figure 2 , Figures 4 to 6 As shown, the body 1 is provided with a position sensing member 6 at the inner end corresponding to the first slot 11; specifically, the position sensing member 6 can be a sensor element or other element that can quickly sense the card. It should be noted that the inner end refers to the end of the first slot 11 away from its own notch, and the reagent card 50 enters the first slot 11 through the notch of the first slot 11. It can be understood that when the reagent card 50 is inserted into the first slot 11, the reagent card 50 reaches the position sensing member 6 at this time, and the insertion signal is transmitted through the position sensing member 6 to start the drive device 3. At this time, the drive device 3 is pushed to the preset position in the first slot 11 by the push member 2 to complete the card insertion operation. Therefore, the position sensing member 6 can quickly sense whether the reagent card 50 is inserted into the first slot 11, and transmit a signal through the position sensing member 6 to start the pushing operation of the push member 2, forming an automatic card pushing operation, thereby improving the automation performance of the card insertion device 10.

[0060] In some embodiments, Figure 4As shown, the in-place sensing member 6 is a long strip structure, and the in-place sensing member 6 is tiltedly arranged on the body 1 relative to the inner end of the first slot 11. It can be understood that by tilting the in-place sensing member 6, the in-place sensing member 6 can adapt to the position of the reagent card 50 inserted into the first slot 11 at will, and can quickly sense the reagent cards 50 at different positions, thereby increasing the sensing coverage area.

[0061] In some embodiments, Figure 2 As shown, the body 1 is also provided with a second slot 12, which is arranged parallel to the first slot 11 and independently of each other. It can be understood that the second slot 12 is used to plug in a conventional single-link card, so that the existing single-link card can be directly inserted into the second slot 12 for fixing, further improving the versatility of the card insertion device 10, so as to be able to adapt to reagent cards 50 of different types and models. It should be noted that the inner end of the second slot 12 can also be provided with a position sensing member 6 for sensing whether the reagent card 50 is inserted in place, and the body 1 can also be provided with a positioning member 22 or a positioning groove 52 corresponding to the second slot 12, so as to form a positioning effect and mechanical touch after the reagent card 50 is inserted.

[0062] A fluorescent immunoassay analyzer 100, such as Figure 1 As shown, the fluorescent immunoassay analyzer 100 includes a mounting seat 20, a mobile device 30, an optical device 40 and the above card insertion device 10. The mobile device 30 and the card insertion device 10 are both arranged on the mounting seat 20, the output end of the mobile device 30 is connected to the optical device 40, the mobile device 30 can drive the optical device 40 to move to the upper area of ​​the first slot 11, and the optical device 40 can scan and identify the reagent card 50 inserted in the first slot 11 and perform optical acquisition. It can be understood that the mobile device 30, the optical device 40 and the card insertion device 10 are all integrated on the mounting seat 20, which can improve the integration of the fluorescent immunoassay analyzer 100.

[0063] Specifically, in this embodiment, Figures 1 to 9As shown, the user inserts the reagent card 50 into the first slot 11. At this time, the pusher 2 controls the driving device 3 to drive the pusher 2 to extend into the first slot 11 along the width direction of the first slot 11 according to the position of the reagent card 50 in the first slot 11 to abut against the reagent card 50, so that the slot wall on the side of the first slot 11 away from the pusher 2 and the pusher 2 jointly clamp the reagent card 50, so that the reagent card 50 is firmly fixed in the first slot 11, and then the moving device 30 drives the optical device 40 to move to above the reagent card 50 in the first slot 11 to complete the code scanning and optical acquisition of the reagent card 50. Specifically, the mobile device 30 includes a first mobile mechanism 31 and a second mobile mechanism 32, wherein the first mobile mechanism 31 is arranged on the second mobile mechanism 32, and the first mobile mechanism 31 can move in a first direction, the optical device 40 is arranged on the first mobile mechanism 31, and the body 1 is arranged on the second mobile mechanism 32, and the second mobile mechanism 32 can move in a second direction. Therefore, through the cooperation of the first mobile mechanism 31 and the second mobile mechanism 32, the optical device 40 can be driven to move to any position above the body 1 in a two-dimensional plane. Specifically in this embodiment, the first mobile mechanism 31 can be a left-right mobile mechanism, driving the optical device 40 to move in the left-right direction, and the second mobile mechanism 32 can be a front-back mobile mechanism, driving the body 1 to move in the front-back direction. Further, the first mobile mechanism 31 and the second mobile mechanism 32 can both be devices that can drive linear motion, such as servo motor screw structures, and are not particularly limited here.

[0064] In summary, the fluorescent immunoassay analyzer 100 is provided with a card insertion device 10, and the card insertion device 10 drives the pusher 2 to move into or out of the first slot 11 along the width direction of the first slot 11 through the driving device 3, so as to be able to adjust the position of the pusher 2 in the first slot 11 according to the width of the card inserted into the first slot 11, such as the reagent card 50, so that the slot wall of the first slot 11 away from the pusher 2 and the pusher 2 jointly clamp the reagent card 50 so that the reagent card 50 is firmly fixed in the first slot 11. Therefore, the first slot 11 of the card insertion device 10 can adapt to reagent cards 50 of different widths, and supports the reagent card 50 to be inserted into the first slot 11 at will and positioned and firmly clamped, without the need to accurately insert the first slot 11, and without the need to be equipped with different types of brackets to firmly clamp the reagent card 50, and can simultaneously load and remove multiple cards, and has the characteristics of simple structure and simple and convenient operation.

[0065] The present invention further provides a control method for the card insertion device 10. The control method is based on the above card insertion device 10 and includes the following steps:

[0066] S100 , inserting the card into the first slot 11 of the body 1 ; when the card is inserted into the first slot 11 , the in-position sensor 6 can sense an insertion signal to start the driving device 3 .

[0067] S200, according to the position of the card component in the first slot 11, the driving device 3 is controlled to drive the pushing member 2 to extend into the first slot 11 along the width direction of the first slot 11 to abut against the card component; at this time, the pushing member 2 and the card component such as the reagent card 50 are adjusted to an offset position through the first matching member and the second matching member to support the user to insert the card at will.
