[0024] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0025] Example 1: Figures 1 to 4 A fluorescent immunoassay card feeding structure shown in the figure comprises a workbench 9, on which a support plate 1 is fixed by a support frame 21, a guide is passed through the middle of the support plate 1 to form a card feeding channel 2, so that the support plate 1 is divided into two left and right support plates, and a driving device 10 is also arranged on the workbench 9, the driving device 10 comprises a driving motor 10.2, two driving wheels 10.3, one driving wheel is fixedly connected to the output end of the driving motor 10.2, and the other driving wheel is fixed on the workbench 9, and the two driving wheels 10.3 are connected by a conveyor belt 10.1 for transmission. When the driving motor 10.2 is started, the conveyor belt 10.1 is driven; the transmission direction of the conveyor belt 10.1 is parallel to the direction of the card feeding channel 2. A guide rail 10.4 is also provided on the workbench 9. The length direction of the guide rail 10.4 is consistent with the transmission direction of the conveyor belt 10.1. A slider (not shown in the figure) is provided on the guide rail 10.4. The slider structure is fixedly connected to the conveyor belt 10.1, so that when the conveyor belt 10.1 moves, it will drive the slider structure to move on the guide rail 10.4. It should be noted that the driving mode of the drive motor 10.2 is forward and reverse rotation, thereby driving the conveyor belt 10.1 to reciprocate forward and reverse transmission, that is, driving the slider structure to slide back and forth on the guide rail 10.4.
[0026] A guide plate 3 is also connected to the slider structure. The guide plate 3 is an L-shaped plate, and one end of the guide plate 3 is arranged horizontally and the other end is arranged vertically. The vertical end of the guide plate 3 is fixedly connected to the slider structure. Two guide columns 5 are arranged on the horizontal end of the guide plate 3, and a card-feeding push bar 4 is slidably connected to the guide column 5; the card-feeding push bar 4 includes a push bar base 4.1 and a push bar protrusion 4.2, and the push bar base 4.1 is provided with two sliding holes, which are slidably connected to the guide column 5, so that the entire card-feeding push bar 4 can slide on the guide column 5.
[0027] It should be noted that the guide plate 3 is located directly below the card entry channel 2, and an elastic member 6 is provided between the card entry push strip 4 and the guide plate 3. Specifically, the elastic member 6 is a spring structure and has two springs, which are respectively sleeved on the two guide posts 5, and one end of the spring abuts against the bottom of the push strip base 4.1, and the other end abuts against the guide plate 3; in a normal state, the elastic member 6 will lift the card entry push strip 4, so that the push strip protrusion 4.2 at the top of the card entry push strip 4 protrudes from the surface of the support plate 1. The push strip base 4.1 is a rectangular parallelepiped as a whole, and the push strip protrusion 4.2 is provided in the middle position of the push strip base 4.1, and a limit block is provided on the side of the guide post 5 away from the guide plate 3. When the push bar base 4.1 slides in the guide column 5, the top height of the card push bar 4 can be changed. The limit block on the guide column 5 can prevent the push bar base 4.1 from detaching from the guide column 5. When the push bar base 4.1 contacts the limit block, the push bar base 4.1 moves to the upper limit position. At this time, the top position of the card push bar 4 is higher than the position of the support plate 1. Specifically, the guide column 5 can adopt a shoulder screw structure, and the limit block is a nut structure of the shoulder screw.
[0028] When the driving motor 10.2 drives the conveyor belt 10.1 to reciprocate, the guide plate 3 is driven to reciprocate along the card feeding channel 2, and the card feeding push bar 4 on the guide plate 3 also reciprocates along the card feeding channel 2. When a reagent card is placed on the card feeding channel 2, the card feeding push bar 4 can push the reagent card 20 to the next station.
[0029] Two limiting plates 7 are arranged on the support plate 1, and the limiting plates 7 are symmetrically distributed on both sides of the card input channel 2. The two limiting plates 7 are arranged in an inverted L shape on the support plate 1. The height of the limiting plates 7 is adapted to the thickness of the reagent card 20, and the distance between the two limiting plates 7 is adapted to the width of the reagent card 20. The two limiting plates 7 are arranged in an inverted L shape, and a card input slot 8 is formed between the two limiting plates 7, which can also prevent the reagent card 20 from escaping from the card input slot 8 in the vertical direction, and play a certain limiting role on the reagent card 20.
[0030] A wedge-shaped opening is provided at one end of the two limit plates 7, and the wedge-shaped opening is provided at the card inlet end of the card inlet slot 8. An oblique opening is also provided at the card inlet end of the card inlet channel 2 of the support plate 1. Both the wedge-shaped opening and the oblique opening have a guiding function, which is beneficial for the reagent card 20 to enter the card inlet slot 8 and the push strip protrusion 4.2 to enter the card inlet channel 2.
[0031] Two sensors are also arranged on the tooling table 9, namely, a first sensor 22 and a second sensor 23. The first sensor 22 is arranged at the initial end of the card-input push bar 4, and the second sensor 23 is arranged at the terminal end of the card-input push bar 4. The initial end of the card-input push bar 4 is a push bar protrusion 4.2 located at the card-input end position of the card-input channel 2, and the terminal end of the card-input push bar 4 is a push bar protrusion 4.2 located at the card-output end position of the card-input channel 2. The first sensor 22 and the second sensor 23 are used to control the start and stop of the driving motor 10.2 to prevent the card-input push bar 4 from excessively moving in the card-input channel 2 and exceeding the travel range.
[0032] The specific card feeding process is as follows: first, manually place the reagent card 20 at the position of the card feeding channel 2 of the support plate 1, and use the reagent card 20 to press down the card feeding push strip 4, and the elastic member 6 at the bottom of the card feeding push strip 4 is compressed so that the top of the push strip protrusion 4.2 of the card feeding push strip 4 is flush with the support plate 1, so that the reagent card 20 can be placed in the card feeding slot 8, and then the reagent card 20 is completely placed in the card feeding slot 8; at this time, the card feeding push strip 4 is separated from the lower part of the reagent card 20, and the card feeding push strip 4 is reset under the elastic force of the elastic member 6, and the height of the top of the push strip protrusion 4.2 is higher than the surface of the support table 1 and is flush with the reagent card 20 is flush with the surface; then the driving motor 10.2 is started, driving the push strip protrusion 4.2 to move toward the inner side of the card feeding channel 2, the push strip protrusion 4.2 abuts against the end of the reagent card 20, and pushes the reagent card 20 to slide in the card feeding slot 8. When the second sensor 23 detects the guide plate 3, the driving motor 10.2 stops running. At this time, when the reagent card 20 is out of the card feeding slot, it enters the next station, and then the driving motor 10.2 is reversed to drive the card feeding push strip 4 to move back. When the first sensor 22 detects the guide plate 3, the driving motor 10.2 stops, and then enters the next working cycle.

[0034] A guide plate 3 is also connected to the slider structure. The guide plate 3 is an L-shaped plate, and one end of the guide plate 3 is arranged horizontally and the other end is arranged vertically.

[0035] It should be noted that the guide plate 3 is located directly below the card entry channel 2, and an elastic member 6 is provided between the card entry push strip 4 and the guide plate 3. Specifically, the elastic member 6 is a spring structure and has two springs, which are respectively sleeved on the two guide posts 5, and one end of the spring abuts against the bottom of the push strip base 4.1, and the other end abuts against the guide plate 3; in a normal state, the elastic member 6 will lift the card entry push strip 4, so that the push strip protrusion 4.2 at the top of the card entry push strip 4 protrudes from the surface of the support plate 1. The push strip base 4.1 is a rectangular parallelepiped as a whole, and the push strip protrusion 4.2 is provided in the middle position of the push strip base 4.1, and a limit block is provided on the side of the guide post 5 away from the guide plate 3. When the push bar base 4.1 slides in the guide column 5, the top height of the card push bar 4 can be changed. The limit block on the guide column 5 can prevent the push bar base 4.1 from detaching from the guide column 5. When the push bar base 4.1 contacts the limit block, the push bar base 4.1 moves to the upper limit position. At this time, the top position of the card push bar 4 is higher than the position of the support plate 1. Specifically, the guide column 5 can adopt a shoulder screw structure, and the limit block is a nut structure of the shoulder screw.
[0036] When the driving motor 10.2 drives the conveyor belt 10.1 to reciprocate, the guide plate 3 is driven to reciprocate along the card feeding channel 2, and the card feeding push bar 4 on the guide plate 3 also reciprocates along the card feeding channel 2. When a reagent card is placed on the card feeding channel 2, the card feeding push bar 4 can push the reagent card 20 to the next station.
[0037] Two limiting plates 7 are arranged on the support plate 1, and the limiting plates 7 are symmetrically distributed on both sides of the card input channel 2. The two limiting plates 7 are arranged in an inverted L shape on the support plate 1. The height of the limiting plates 7 is adapted to the thickness of the reagent card 20, and the distance between the two limiting plates 7 is adapted to the width of the reagent card 20. The two limiting plates 7 are arranged in an inverted L shape, and a card input slot 8 is formed between the two limiting plates 7, which can also prevent the reagent card 20 from escaping from the card input slot 8 in the vertical direction, and play a certain limiting role on the reagent card 20.
[0038] A wedge-shaped opening is provided at one end of the two limit plates 7, and the wedge-shaped opening is provided at the card inlet end of the card inlet slot 8. An oblique opening is also provided at the card inlet end of the card inlet channel 2 of the support plate 1. Both the wedge-shaped opening and the oblique opening have a guiding function, which is beneficial for the reagent card 20 to enter the card inlet slot 8 and the push strip protrusion 4.2 to enter the card inlet channel 2.
[0039] Two sensors are also arranged on the tooling table 9, namely, a first sensor 22 and a second sensor 23. The first sensor 22 is arranged at the initial end of the card-input push bar 4, and the second sensor 23 is arranged at the terminal end of the card-input push bar 4. The initial end of the card-input push bar 4 is a push bar protrusion 4.2 located at the card-input end position of the card-input channel 2, and the terminal end of the card-input push bar 4 is a push bar protrusion 4.2 located at the card-output end position of the card-input channel 2. The first sensor 22 and the second sensor 23 are used to control the start and stop of the driving motor 10.2 to prevent the card-input push bar 4 from excessively moving in the card-input channel 2 and exceeding the travel range.
[0040] In addition, if Figure 5 and Figure 6 As shown, a disc-shaped incubation plate 11 is also arranged next to the card-entry structure, a mounting hole is arranged in the middle of the incubation plate 11, a turntable 16 mechanism is arranged in the mounting hole, and a plurality of cover plates 13 are arranged on the incubation plate 11, the cover plates 13 are in a triangular shape, and are evenly distributed along the circumference of the incubation plate 11, so that a card slot 12 is formed between adjacent cover plates 13, and the direction of the card slot 12 is along the radial direction of the incubation plate 11. Among them, the turntable 16 is fixedly connected to the cover plate 13 on the incubation plate 11, and the turntable 16 is driven by a rotating motor 24. After the rotating motor 24 is started, the turntable 16 is driven to rotate, and the turntable 16 drives the cover plate 13 on the incubation plate 11 to rotate, and the reagent card 20 is in the card slot 12 formed by the cover plate 13, so the reagent card 20 moves on the surface of the incubation plate 11 along with the cover plate 13. The incubation plate 11 is located on the upper side of the workbench 9 and is flush with the support plate 1 , so that the card slot 12 on the incubation plate 11 is docked with the card input slot 8 on the support plate 1 , ensuring that the reagent card 20 in the card input slot 8 can enter the card slot 12 .
[0041] It should be noted that the rotating motor 24 rotates intermittently. Each time the rotating motor 24 rotates, the next adjacent card slot 12 rotates to a position aligned with the card feed slot 8, thereby ensuring that the card feed slot 8 continuously feeds the incubation plate 11.
[0042] The cover plate 13 is provided with a bump 14 structure on both sides. The bump 14 is arranged at the card entry end of the card slot 12, so that each card slot 12 has two bumps 14 at the card entry end. The bump 14 is arranged on the upper surface of the cover plate 13, that is, above the card slot 12, so that after the reagent card 20 enters the card slot 12, there will be no obvious displacement in the vertical direction, which plays a role in limiting the reagent card 20 in the card slot 12.
[0043] A spring sheet 15 is provided on both sides of the cover plate 13. The spring sheet 15 is provided on both sides of the card slot 12. One end of the spring sheet 15 is fixed to the upper surface of the cover plate 13, and the other end faces the card slot 12 and is bent and extended into the card slot 12 so that the end portion is in a horizontal state. Therefore, when the reagent card 20 enters the card slot 12, the spring sheet 15 will press against the upper surface of the reagent card 20 and apply a tightening force to the reagent card 20. On the one hand, it limits the displacement of the reagent card 20 in the vertical direction. On the other hand, it prevents the centrifugal force from causing the reagent card 20 to radially separate from the incubation plate 11 during the rotation of the cover plate 13.
[0044] A third sensor 25 is also provided between the card input slot 8 and the card slot 12. The third sensor 25 can detect whether there is a reagent card 20 between the card input slot 8 and the card slot 12. When the reagent card 20 completely enters the card slot 12, the third sensor 25 will feedback a signal to start the rotating motor 24 to rotate once.
[0045] A platform 17 is also provided on the upper surface of the incubation plate 11, and a through hole 18 is provided on the platform 17. Specifically, the through hole 18 is located at the position corresponding to the reagent card 20 when the reagent card 20 enters the card slot 12 from the card input slot 8 and the rotating motor 24 rotates once. A code scanning module 19 is provided at the position of the through hole 18, and the code scanning module 19 can scan the QR code 20.1 on the reagent card 20.
[0046] The specific card feeding process is as follows: first, manually place the reagent card 20 at the position of the card feeding channel 2 of the support plate 1, and use the reagent card 20 to press down the card feeding push strip 4, and the elastic member 6 at the bottom of the card feeding push strip 4 is compressed, so that the top of the push strip protrusion 4.2 of the card feeding push strip 4 is flush with the support plate 1, so that the reagent card 20 can be placed in the card feeding slot 8, and then the reagent card 20 is completely placed in the card feeding slot 8; at this time, the card feeding push strip 4 is separated from the lower part of the reagent card 20, and the card feeding push strip 4 is reset under the elastic force of the elastic member 6, and the height of the top of the push strip protrusion 4.2 is higher than the surface of the support platform 1 and is flush with the surface of the reagent card 20. The surface is flush; then the driving motor 10.2 is started, driving the push strip protrusion 4.2 to move toward the inside of the card input channel 2, the push strip protrusion 4.2 abuts against the end of the reagent card 20, and pushes the reagent card 20 to slide in the card input slot 8. When the second sensor 23 detects the guide plate 3, the driving motor 10.2 stops running. At this time, when the reagent card 20 is out of the card input slot, it will completely enter the card slot of the incubation plate, and then the driving motor 10.2 is reversed, driving the card input push strip 4 to move back. When the first sensor 22 detects the guide plate 3, the driving motor 10.2 stops, and then enters the next working cycle.
[0047] After the reagent card 20 completely enters the card slot 12, the rotating motor 24 rotates once, and the reagent card 20 is rotated to the position of the through hole 18. At this time, the reagent card 20 is aligned with the code scanning module 19, and the code scanning module 19 scans the QR code 20.1 on the reagent card 20. After scanning and identification, when the next reagent card 20 enters the card slot 12, the rotating motor 24 rotates again, so that the scanned reagent card 20 is gradually transferred to the card ejection structure; and the above working cycle is repeated.
