DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: A novel card input structure of a fluorescent immunoassay analyzer, such as Figure 1 and Figure 2 As shown, it includes a tooling platform 8, on which a card feeding device, a driving device 10 and a support plate 7 are arranged. The card feeding device includes a card feeding push strip 3, a fixing frame 2 and a cam 4, wherein the support plate 7 is fixed to the right edge position of the tooling platform 8 by a supporting frame 21, and two support plates 7 are arranged, and the two support plates 7 are distributed at intervals to form a card feeding aisle 9 between the two support plates 7. A driving device 10 is arranged below the support plate 7 and on the upper side of the tooling platform 8. The driving device 10 includes a driving motor 10.2, a driving wheel 10.3, a driven wheel 10.4 and a conveyor belt 10.1. The driving wheel 10.3 is connected to the output end of the driving motor 10.2, and the driven wheel 10.4 is fixed to the side of the tooling platform 8 away from the driving motor 10.2. The conveyor belt 10.1 is connected to the driving wheel 10.3 and the driven wheel 10.4, and the movement direction of the conveyor belt 10.1 is parallel to the card feeding aisle 9.

[0027] A fixed frame 2 is fixed on the conveyor belt 10.1, and the conveyor belt 10.1 can drive the fixed frame 2 to move. In order to ensure the stable movement of the fixed frame 2, a guide rail 10.5 is also provided on the tooling platform 8, and the fixed frame 2 is also slidably connected to the guide rail 10.5. The fixed frame 2 includes a first fixed plate 2.1 and a second fixed plate 2.2. The first fixed plate 2.1 is horizontally arranged below the support plate 7 and corresponds to the position of the card entry aisle 9. Two vertically arranged first guide columns 22 are provided on the first fixed plate 2.1, and the first guide column 22 is slidably connected with the card entry push bar 3. The card-input push strip 3 includes a card-input protrusion 3.1 and a card-input base 3.2. The card-input protrusion 3.1 is arranged on the upper surface of the card-input base 3.2. The card-input base 3.2 is provided with two through holes to cooperate with the first guide column 22. A first spring 23 is sleeved between the card-input base 3.2 and the first fixed plate 2.1 and on the outside of the first guide column 22. One end of the first spring 23 abuts against the upper surface of the first fixed plate 2.1, and the other end of the first spring 23 abuts against the lower surface of the card-input base 3.2, so that under the action of the first spring 23, the card-input push strip 3 can move in the vertical direction. The second fixed plate 2.2 is arranged vertically, and a cam 4 structure is rotatably arranged on one side of the second fixed plate 2.2; the first fixed plate 2.1 and the second fixed plate 2.2 are spaced apart.

[0028] Among them, the driving motor 10.2 works in forward and reverse rotation, so that the conveyor belt 10.1 reciprocates in the horizontal direction. The conveyor belt 10.1 drives the card entry push bar 3 and the cam 4 structure on the fixed frame 2 to reciprocate together, and the card entry aisle 9 corresponds to the position of the card entry push bar 3, so that the card entry push bar 3 will move in the card entry aisle 9.

[0029] Continue, as Figure 4 and Figure 5As shown, the height of the incubation plate 1 is flush with the height of the support plate 7. Since the support plate 7 is arranged at the right edge of the tooling platform 8, the left part of the support plate 7 is entirely located at the lower side of the incubation plate 1, thereby hiding most of the structures on the tooling platform 8, and improving the aesthetics and simplicity of the entire device; a limiting hole 5 is arranged on the incubation plate 1, and a card entry block 6 is slidably connected in the limiting hole 5. Specifically, two second guide columns 24 are fixedly connected to the lower side of the incubation plate 1. Specifically, the second guide column 24 can adopt a shoulder screw structure, so that the bottom of the second guide column 24 is a nut structure. A card entry block base 13 is slidably connected to the second guide column 24, and the card entry block base 13 is provided with two through holes that cooperate with the two second guide columns 24. The nut structure on the second guide column 24 can limit the card entry block base 13 to prevent the card entry block base 13 from separating from the second guide column 24. A second spring 25 is provided between the upper surface of the card entry block base 13 and the lower surface of the incubation plate 1 and on the outside of the second guide column 24, one end of the second spring 25 abuts against the upper surface of the card entry block base 13, and the other end of the second spring 25 abuts against the lower surface of the incubation plate 1.

[0030] like Figure 4 As shown, the distance between the card entry push strip 3 and the cam 4 is smaller than the distance between the card entry block 6 (or the limiting hole 5) and the edge of the incubation plate 1. Figure 4 It is the initial position of the card feeding operation, at this time, the cam 4 abuts against the lower surface of the card feeding block base 13, and lifts the card feeding block 6, so that the top of the card feeding block 6 protrudes between 3mm and 4mm from the surface of the incubation plate 1, and the card feeding push bar 3 is pressed down by the action of the reagent card 20, and the first spring 23 is in a compressed state. When the reagent card 20 is transported to the incubation plate 1 through the card feeding aisle 9, the reagent card 20 will be blocked by the card feeding block 6 at this time. If the reagent card 20 fails the test, or it is a wrong reagent card 20, the reagent card 20 can be taken out (because the reagent card 20 has not been completely placed in the incubation plate 1).

[0031] like Figure 8 As shown, the structure of the reagent card 20 in this solution is shown, and a two-dimensional code 20.1 structure is provided on the reagent card 20.

[0032] After the reagent card 20 has passed the inspection, the driving motor 10.2 is started to drive the conveyor belt 10.1 to move, and the conveyor belt 10.1 drives the fixed frame 2 to move to the right, so that the cam 4 and the card inlet push strip 3 on the fixed frame 2 all move to the right together, and the card inlet block base 13 loses the pushing effect of the cam 4 and begins to fall back under the action of the second spring 25 and its own gravity, and makes the top of the card inlet block 6 lower than the upper surface position of the incubation plate 1. When the conveyor belt 10.1 continues to drive the fixed frame 2 to move to the right limit position, the card inlet push strip 3 is just located on the outside of the support frame 7 and makes the card inlet push strip 3 just separate from the lower surface of the reagent card 20, so that the card inlet push strip 3 loses the effect of the reagent card 20, and under the action of the first spring 23, the card inlet base 3.2 is pushed up by the first spring 23, so that the card inlet cam Block 3.1 is lifted up, and the top position of the card-input push strip 3 is flush with or higher than the position of the reagent card 20 and close to the end face of the reagent card 20. After the driving motor 10.2 drives the fixed frame 2 to move to the right limit, it drives in the opposite direction, and the conveyor belt 10.1 drives the fixed frame 2 to move left, thereby driving the cam 4 and the card-input push strip 3 to move left, and the card-input push strip 3 drives the reagent card 20 into the incubation plate 1. When the card-input push strip 3 moves left to the edge of the incubation plate 1, the reagent card 20 is completely pushed into the incubation plate 1. Since the distance between the cam 4 and the card-input push strip 3 is less than the distance from the card-input block 6 (or the limit hole 5) to the edge of the incubation plate 1, the cam 4 does not contact the card-input block 6 at this time, thereby preventing the card-input block 6 from bulging and lifting or damaging the reagent card 20.

[0033] At this time, since the reagent card 20 is completely entered into the incubation plate 1, the second card feed slot 12 rotates once, so that the reagent card 20 is sent to the next workstation, and the empty space on the incubation plate 1 is rotated to be aligned with the cam 4 and the card feed push strip 3, and then the drive motor 10.2 continues to start, so that the conveyor belt 10.1 continues to drive the fixed frame 2 to move a certain distance to the left, so that the cam 4 can continue to abut against the next card feed block base 13, and lift the card feed block 6 to the surface of the incubation plate 1.

[0034] It should be noted that a wedge-shaped surface 14 is provided at the bottom of the card feed block base 13, which is used to cooperate with the cam 4 so that the cam 4 can move to the lower side of the card feed block base 13 to lift the card feed block 6, and an escape groove 26 is also provided on the edge of the corresponding position of the incubation plate 1, which is used for allowing the card feed push bar 3 to move a certain distance into the incubation plate 1 (only in this way can the cam 4 move back to the lower side of the card feed block base 13) to avoid jamming between the card feed push bar 3 and the incubation plate 1.

[0035] like Figure 1 or Figure 3As shown, a first sensor 15 and a second sensor 16 are also provided on the tooling platform 8, and the first sensor 15 and the second sensor 16 are arranged along the moving direction of the conveyor belt 10.1. A sensing plate 17 is provided on one side of the second fixed plate 2.2 close to the first sensor 15 and the second sensor 16. When the sensing plate 17 moves to the position of the first sensor 15, the driving motor 10.2 stops running, the cam 4 abuts against the card feed baffle base 13, and lifts the card feed block 6. When the sensing plate 17 moves to the second sensor 16, the driving motor 10.2 stops running, the cam 4 disengages from the card feed baffle base 13, and the card feed push strip 3 moves to the outside of the support plate 7, and the top position of the card feed protrusion 3.1 is higher than the position of the support plate 7, so that the reagent card 20 on the support plate 7 can be fed into the card.

[0036] Two limit plates 27 are arranged on the two support plates 7, and the two limit plates 27 form a first card feeding slot 11. A fourth sensor 28 and a fifth sensor 29 are arranged at both ends of the first card feeding slot 11. The fourth sensor 28 and the fifth sensor 29 can detect whether the reagent card 20 is inserted in place. After the reagent card 20 is inserted in place, the driving motor 10.2 can be started, so that the card feeding device performs the card feeding operation.

[0037] like Figure 6 or Figure 7 As shown, the incubation plate 1 is a disc-shaped structure, and a plurality of second card-feeding slots 12 are arranged circumferentially on the incubation plate 1. The direction of the second card-feeding slots 12 is arranged along the radial direction of the incubation plate 1. A rotating motor 30 is arranged at the bottom of the incubation plate 1. The rotating motor 30 is intermittently driven. Each time the rotating motor 30 is started, the second card-feeding slot 12 rotates once, so that the second card-feeding slot 12 rotates one position, and it can always be ensured that there is a second card-feeding slot 12 connected with the first card-feeding slot 11. Thus, the continuous feeding work on the incubation plate 1 is completed.

[0038] In this embodiment, a heating plate is attached to the bottom of the incubation plate, and insulation cotton is arranged under the heating plate to heat and keep the incubation plate warm. For a multi-channel fluorescent immunoassay analyzer, the reagent reaction in the reagent card requires a specific temperature and a certain time.

[0039] Example 2: A novel card input structure of a fluorescent immunoassay analyzer, such as Figure 1 and Figure 2As shown, it includes a tooling platform 8, on which a card feeding device, a driving device 10 and a support plate 7 are arranged. The card feeding device includes a card feeding push strip 3, a fixing frame 2 and a cam 4, wherein the support plate 7 is fixed to the right edge position of the tooling platform 8 by a supporting frame 21, and two support plates 7 are arranged, and the two support plates 7 are distributed at intervals to form a card feeding aisle 9 between the two support plates 7. A driving device 10 is arranged below the support plate 7 and on the upper side of the tooling platform 8. The driving device 10 includes a driving motor 10.2, a driving wheel 10.3, a driven wheel 10.4 and a conveyor belt 10.1. The driving wheel 10.3 is connected to the output end of the driving motor 10.2, and the driven wheel 10.4 is fixed to the side of the tooling platform 8 away from the driving motor 10.2. The conveyor belt 10.1 is connected to the driving wheel 10.3 and the driven wheel 10.4, and the movement direction of the conveyor belt 10.1 is parallel to the card feeding aisle 9.

[0040] A fixed frame 2 is fixed on the conveyor belt 10.1, and the conveyor belt 10.1 can drive the fixed frame 2 to move. In order to ensure the stable movement of the fixed frame 2, a guide rail 10.5 is also provided on the tooling platform 8, and the fixed frame 2 is also slidably connected to the guide rail 10.5. The fixed frame 2 includes a first fixed plate 2.1 and a second fixed plate 2.2. The first fixed plate 2.1 is horizontally arranged below the support plate 7 and corresponds to the position of the card entry aisle 9. Two vertically arranged first guide columns 22 are provided on the first fixed plate 2.1, and the first guide column 22 is slidably connected with the card entry push bar 3. The card-input push strip 3 includes a card-input protrusion 3.1 and a card-input base 3.2. The card-input protrusion 3.1 is arranged on the upper surface of the card-input base 3.2. The card-input base 3.2 is provided with two through holes to cooperate with the first guide column 22. A first spring 23 is sleeved between the card-input base 3.2 and the first fixed plate 2.1 and on the outside of the first guide column 22. One end of the first spring 23 abuts against the upper surface of the first fixed plate 2.1, and the other end of the first spring 23 abuts against the lower surface of the card-input base 3.2, so that under the action of the first spring 23, the card-input push strip 3 can move in the vertical direction. The second fixed plate 2.2 is arranged vertically, and a cam 4 structure is rotatably arranged on one side of the second fixed plate 2.2; the first fixed plate 2.1 and the second fixed plate 2.2 are spaced apart.

[0041] Among them, the driving motor 10.2 works in forward and reverse rotation, so that the conveyor belt 10.1 reciprocates in the horizontal direction. The conveyor belt 10.1 drives the card entry push bar 3 and the cam 4 structure on the fixed frame 2 to reciprocate together, and the card entry aisle 9 corresponds to the position of the card entry push bar 3, so that the card entry push bar 3 will move in the card entry aisle 9.

[0042] Continue, as Figure 4 and Figure 5As shown, the height of the incubation plate 1 is flush with the height of the support plate 7. Since the support plate 7 is arranged at the right edge of the tooling platform 8, the left part of the support plate 7 is entirely located at the lower side of the incubation plate 1, thereby hiding most of the structures on the tooling platform 8, and improving the aesthetics and simplicity of the entire device; a limiting hole 5 is arranged on the incubation plate 1, and a card entry block 6 is slidably connected in the limiting hole 5. Specifically, two second guide columns 24 are fixedly connected to the lower side of the incubation plate 1. Specifically, the second guide column 24 can adopt a shoulder screw structure, so that the bottom of the second guide column 24 is a nut structure. A card entry block base 13 is slidably connected to the second guide column 24, and the card entry block base 13 is provided with two through holes that cooperate with the two second guide columns 24. The nut structure on the second guide column 24 can limit the card entry block base 13 to prevent the card entry block base 13 from separating from the second guide column 24. A second spring 25 is provided between the upper surface of the card entry block base 13 and the lower surface of the incubation plate 1 and on the outside of the second guide column 24, one end of the second spring 25 abuts against the upper surface of the card entry block base 13, and the other end of the second spring 25 abuts against the lower surface of the incubation plate 1.

[0043] like Figure 4 As shown, the distance between the card entry push strip 3 and the cam 4 is smaller than the distance between the card entry block 6 (or the limiting hole 5) and the edge of the incubation plate 1. Figure 4 It is the initial position of the card feeding operation, at this time, the cam 4 abuts against the lower surface of the card feeding block base 13, and lifts the card feeding block 6, so that the top of the card feeding block 6 protrudes between 3mm and 4mm from the surface of the incubation plate 1, and the card feeding push bar 3 is pressed down by the action of the reagent card 20, and the first spring 23 is in a compressed state. When the reagent card 20 is transported to the incubation plate 1 through the card feeding aisle 9, the reagent card 20 will be blocked by the card feeding block 6 at this time. If the reagent card 20 fails the test, or it is a wrong reagent card 20, the reagent card 20 can be taken out (because the reagent card 20 has not been completely placed in the incubation plate 1).

[0044] like Figure 8 As shown, the structure of the reagent card 20 in this solution is shown, and a two-dimensional code 20.1 structure is provided on the reagent card 20.

[0045] After the reagent card 20 has passed the inspection, the driving motor 10.2 is started to drive the conveyor belt 10.1 to move, and the conveyor belt 10.1 drives the fixed frame 2 to move to the right, so that the cam 4 and the card inlet push strip 3 on the fixed frame 2 all move to the right together, and the card inlet block base 13 loses the pushing effect of the cam 4 and begins to fall back under the action of the second spring 25 and its own gravity, and makes the top of the card inlet block 6 lower than the upper surface position of the incubation plate 1. When the conveyor belt 10.1 continues to drive the fixed frame 2 to move to the right limit position, the card inlet push strip 3 is just located on the outside of the support frame 7 and makes the card inlet push strip 3 just separate from the lower surface of the reagent card 20, so that the card inlet push strip 3 loses the effect of the reagent card 20, and under the action of the first spring 23, the card inlet base 3.2 is pushed up by the first spring 23, so that the card inlet cam Block 3.1 is lifted up, and the top position of the card-input push strip 3 is flush with or higher than the position of the reagent card 20 and close to the end face of the reagent card 20. After the driving motor 10.2 drives the fixed frame 2 to move to the right limit, it drives in the opposite direction, and the conveyor belt 10.1 drives the fixed frame 2 to move left, thereby driving the cam 4 and the card-input push strip 3 to move left, and the card-input push strip 3 drives the reagent card 20 into the incubation plate 1. When the card-input push strip 3 moves left to the edge of the incubation plate 1, the reagent card 20 is completely pushed into the incubation plate 1. Since the distance between the cam 4 and the card-input push strip 3 is less than the distance from the card-input block 6 (or the limit hole 5) to the edge of the incubation plate 1, the cam 4 does not contact the card-input block 6 at this time, thereby preventing the card-input block 6 from bulging and lifting or damaging the reagent card 20.

[0046] At this time, since the reagent card 20 is completely entered into the incubation plate 1, the second card feed slot 12 rotates once, so that the reagent card 20 is sent to the next workstation, and the empty space on the incubation plate 1 is rotated to be aligned with the cam 4 and the card feed push strip 3, and then the drive motor 10.2 continues to start, so that the conveyor belt 10.1 continues to drive the fixed frame 2 to move a certain distance to the left, so that the cam 4 can continue to abut against the next card feed block base 13, and lift the card feed block 6 to the surface of the incubation plate 1.

[0047] It should be noted that a wedge-shaped surface 14 is provided at the bottom of the card feed block base 13, which is used to cooperate with the cam 4 so that the cam 4 can move to the lower side of the card feed block base 13 to lift the card feed block 6, and an escape groove 26 is also provided on the edge of the corresponding position of the incubation plate 1, which is used for allowing the card feed push bar 3 to move a certain distance into the incubation plate 1 (only in this way can the cam 4 move back to the lower side of the card feed block base 13) to avoid jamming between the card feed push bar 3 and the incubation plate 1.

[0048] like Figure 1 or Figure 3As shown, a first sensor 15 and a second sensor 16 are also provided on the tooling platform 8, and the first sensor 15 and the second sensor 16 are arranged along the moving direction of the conveyor belt 10.1. A sensing plate 17 is provided on one side of the second fixed plate 2.2 close to the first sensor 15 and the second sensor 16. When the sensing plate 17 moves to the position of the first sensor 15, the driving motor 10.2 stops running, the cam 4 abuts against the card feed baffle base 13, and lifts the card feed block 6. When the sensing plate 17 moves to the second sensor 16, the driving motor 10.2 stops running, the cam 4 disengages from the card feed baffle base 13, and the card feed push strip 3 moves to the outside of the support plate 7, and the top position of the card feed protrusion 3.1 is higher than the position of the support plate 7, so that the reagent card 20 on the support plate 7 can be fed into the card.

[0049] Two limit plates 27 are arranged on the two support plates 7, and the two limit plates 27 form a first card feeding slot 11. A fourth sensor 28 and a fifth sensor 29 are arranged at both ends of the first card feeding slot 11. The fourth sensor 28 and the fifth sensor 29 can detect whether the reagent card 20 is inserted in place. After the reagent card 20 is inserted in place, the driving motor 10.2 can be started, so that the card feeding device performs the card feeding operation.

[0050] like Figure 6 or Figure 7 As shown, the incubation plate 1 is a disc-shaped structure, and a plurality of second card-feeding slots 12 are arranged circumferentially on the incubation plate 1. The direction of the second card-feeding slots 12 is arranged along the radial direction of the incubation plate 1. A rotating motor 30 is arranged at the bottom of the incubation plate 1. The rotating motor 30 is intermittently driven. Each time the rotating motor 30 is started, the second card-feeding slot 12 rotates once, so that the second card-feeding slot 12 rotates one position, and it can always be ensured that there is a second card-feeding slot 12 connected with the first card-feeding slot 11. Thus, the continuous feeding work on the incubation plate 1 is completed.

[0051] In addition, if Figure 4 As shown, a code scanning module 18 is provided on the upper side of the incubation plate 1 and at a position corresponding to the second card input slot 12. When the card input operation starts, the operator manually puts the reagent card 20 into the first card input slot 11, and then pushes it into the second card input slot 12 of the incubation plate 1 to tighten it with the card input block 6. At this time, the QR code 20.1 on the reagent card 20 can be aligned with the code scanning module 18. The code scanning module 18 can recognize the QR code 20.1 on the reagent card 20 and identify the reagent card 20. If the reagent card 20 is wrong, the code scanning module 18 will alarm and process. At this time, the operator only needs to take out the wrong reagent card 20. When the code scanning module 18 detects that the information is correct, the drive motor 10.2 is started to start the card input operation.

[0052] Similarly, a third sensor 19 is also provided on the upper side of the incubation plate 1 and at a position corresponding to the second card input slot 12. The third sensor 19 can detect whether there is a reagent card 20 in the second card input slot 12 at the initial state of the device startup. If there is a reagent card 20, the rotating motor 30 is started once to transport the reagent card 20 away. If there is no reagent card 20, the card input operation is performed normally. In addition, after the card input push bar 3 pushes the reagent card 20 into the second card slot 12, the third sensor 19 will also detect whether the reagent card 20 is inserted in place.
