[0002] In the field of immunology, our understanding of the specific binding between antigens and antibodies has deepened, laying the foundation for the development of immunoassay methods. With in-depth research into the immune system, the mechanisms of various immune responses have been gradually revealed, making it possible to use immune responses for detection. Against the backdrop of ever-increasing medical needs, the requirements for early diagnosis, precision treatment, and monitoring of diseases are becoming increasingly stringent. Fluorescence immunoassay analyzers, due to their advantages of speed, sensitivity, accuracy, and ease of operation, are gradually becoming an indispensable detection tool in clinical diagnosis, scientific research, and other related fields.

[0033] Combined with appendix Figure 1 -Appendix Figure 7 A mobile identification device for adding multiple sample strips includes a card shifting mechanism, a card buffer mechanism, and a reading module. The card shifting mechanism is connected to a card compartment 1 for storing sample strips 3 at its transport start end. The card buffer mechanism includes a buffer compartment 4, which is located at the transport end of the card shifting mechanism. The buffer compartment 4 has a card inlet on the side near the card shifting mechanism. Limiting blocks 5 are provided on both sides of the bottom of the buffer compartment 4. The limiting blocks 5 are elastically connected to the side wall of the buffer compartment 4 by springs. The extension and retraction direction of the springs is perpendicular to the side wall of the buffer compartment 4 where the limiting blocks 5 are installed. A space is left between the limiting blocks 5 and the bottom wall of the buffer compartment 4 for placing the sample strips 3.

[0034] A card-pushing mechanism for pushing the sample strip 3 inside the cache compartment 4 upward is connected to one side;

[0035] The judgment module is located on the top of the cache compartment 4. The top of the cache compartment 4 is open and located within the judgment area of ​​the judgment module. The top of the cache compartment 4 is provided with a card dispensing port on the side away from the card moving mechanism. The top of the cache compartment 4 is provided with a card ejection mechanism for pushing the sample strip 3 out of the cache compartment 4 through the card dispensing port.

[0036] Specifically, the card-shifting mechanism includes a base plate 9, on both sides of the base plate 9, a first slide plate 11 is fixed by a support plate 10, a pressure spring 13 is provided above the first slide plate 11, and a space is left between the pressure spring 13 and the first slide plate 11 for the sample strip 3 to be placed. When the pressure spring 13 is in its natural state, the distance between the pressure spring 13 and the first slide plate 11 is less than the thickness of the sample strip 3.

[0037] A push-pull locking mechanism is provided in the middle of the base plate 9. The push-pull locking mechanism includes a movable plate 19 that is slidably connected to the base plate 9. Finger support plates 20 are fixed on both sides of the movable plate 19. A push-lock finger 22 and a pull-lock finger 21 are rotatably connected between the two finger support plates 20. The push-lock finger 22 is located on the side of the movable plate 19 closer to the buffer compartment 4, and the pull-lock finger 21 is located on the side of the movable plate 19 closer to the card compartment 1. The movable plate 19 is provided with two push-pull electromagnets 23 for driving the push-lock finger 22 and the pull-lock finger 21 to rotate, respectively. The base plate 9 is provided with a driving mechanism for driving the movable plate 19 to slide.

[0038] A second slide plate 12 is provided between the two first slide plates 11. A slot 24 is provided between the first slide plate 11 and the second slide plate 12 for the push-card finger 22 and the pull-card finger 21 to move. The push-pull-card mechanism is located between the second slide plate 12 and the base plate 9.

[0039] When the template strip enters the card-moving mechanism, both ends of the template strip are located between the first slide plate 11 and the pressure plate spring on the two first slide plates 11 respectively. The ends of the template strip support the pressure plate spring, and at this time the pressure plate spring tends to return to its original position, applying elastic force to the template strip, thereby fixing the template strip.

[0040] More specifically, a slide rail 14 is fixed on the base plate 9, a sliding block is slidably connected to the slide rail 14, and the moving plate 19 is fixedly connected to the sliding block.

[0041] Specifically, the driving mechanism includes a stepper motor 15, a driving wheel 17, and a driven wheel 18. The driving wheel 17 and the driven wheel 18 are rotatably mounted at opposite ends of one side of the base plate 9. The driving wheel 17 and the driven wheel 18 are connected by a synchronous belt 16. The output end of the stepper motor 15 is connected to the driving wheel 17, and the synchronous belt 16 is fixedly connected to the adjacent finger support plate 20. When the push-pull card mechanism needs to be moved, the stepper motor 15 drives the driving wheel 17 to rotate, which in turn drives the synchronous belt 16 to rotate, thus moving the push-pull card mechanism. The reciprocating movement of the push-pull card mechanism is achieved by the forward and reverse rotation of the stepper motor 15.

[0042] Specifically, the top of the buffer compartment 4 is equipped with a micro switch 44 for detecting the position of the sample strip 3. The micro switch 44 is connected to the main control board 2. When the micro switch 44 detects that the sample strip 3 in the buffer compartment 4 has reached the top of the buffer compartment 4, it means that the buffer compartment 4 is full of sample strips 3 and the top sample strip 3 has reached the reading range of the judgment module. At this time, the main control board 2 sends a command to the card moving mechanism to stop stacking sample strips 3 into the buffer compartment 4 and controls the judgment module to start recognizing and judging the sample strips 3 in the buffer compartment 4.

[0043] Specifically, the output end of the push-pull electromagnet 23 is connected to a connecting rod 28. The push-pull electromagnet 23 is located between the push-card finger 22 and the pull-card finger 21. More specifically, the output end of the push-pull electromagnet 23 is hinged to the connecting rod 28.

[0044] The push-card finger 22 includes a rotating shaft 26 and two finger rods 25. The ends of the two finger rods 25 near the push-pull electromagnet 23 are fixed on the rotating shaft 26. The finger rods 25 extend from both ends of the rotating shaft 26 and are rotatably connected to the two finger support plates 20 respectively. The top of the end of the finger rod 25 away from the push-pull electromagnet 23 is provided with a push-pull block 27. The pull-card finger 21 has the same structure as the push-card finger 22.

[0045] The connecting rods 28 on the output ends of the two push-pull electromagnets 23 are respectively connected to the finger rods 25 of the push-card finger 22 and the pull-card finger 21, with the connecting rods 28 located below the finger rods 25.

[0046] When the output end of the push-pull electromagnet 23 retracts, both the pull-card finger 21 and the push-card finger 22 are located below the second slide plate 12. When the output end of the push-pull electromagnet 23 extends, it drives the corresponding finger rod 25 to rotate, causing the end of the finger rod 25 with the push-pull block 27 to move upward and extend out of the slot 24. At this time, the push-pull block 27 is located above the second slide plate 12. When the push-pull block 27 is located above the second slide plate 12 and the push-pull mechanism moves, the push-pull block 27 can push or pull the sample strip 3 on the second slide plate 12, thereby realizing the pushing or pulling of the sample strip 3. The two push-pull electromagnets 23 can operate independently, thereby realizing the independent operation of the pull-card finger 21 or the push-card finger 22.

[0047] Specifically, the card-pushing mechanism includes a first linear motor 29 and a lifting tray 33. The first linear motor 29 is fixed to the outer wall of the buffer chamber 4. A guide rail 32 is fixed to the outer wall of the buffer chamber 4 on the side away from the card-moving mechanism. A slider connecting plate 30 is slidably connected to the guide rail 32 via a slider. One end of the slider connecting plate 30 is fixedly connected to a nut on the lead screw of the first linear motor 29, and the other end of the slider connecting plate 30 is fixedly connected to the lifting tray 33. The bottom of the buffer chamber 4 has an opening for the lifting tray 33 to enter and exit, and the side of the buffer chamber 4 away from the card-moving mechanism has a through groove for the lifting tray 33 to move. Specifically, a card pad 34 is provided on the top of the lifting tray 33, and the card pad 34 may be made of rubber.

[0048] In its initial state, the card-pushing mechanism's lifting tray 33 is positioned below the opening of the buffer chamber 4. When the card-moving mechanism moves the sample strip 3 from the card inlet into the buffer chamber 4, the sample strip 3 is located in the space between the limiting block 5 and the bottom wall of the buffer chamber 4. At this time, the first linear motor 29 can be started to rotate forward. The first linear motor 29 drives the lifting tray 33 to move upward through the slider connecting plate 30. The lifting tray 33 enters the buffer chamber 4 through the opening and lifts the sample strip 3 located between the limiting block 5 and the bottom wall of the buffer chamber 4. During the upward movement of the sample strip 3, the limiting block 5 contracts due to the squeezing action of the sample strip 3. After the sample strip 3 moves above the limiting block 5, the limiting block 5 loses its squeezing action and extends again under the action of the spring force. At this time, the limiting block 5 can support and limit the sample strip 3 above it, keeping the sample strip 3 in the buffer chamber 4 above the limiting block 5. After the sample strip 3 is moved above the limiting block 5, the first linear motor 29 reverses, driving the lifting tray 33 to move downward, and the lifting tray 33 returns to its original position. By repeating the above actions, multiple sample bars 3 can be stacked in the cache bin 4, and the judgment module can identify and judge the sample bar 3 located at the top.

[0049] More specifically, the bottom of the limiting block 5 has a sloped structure, and the bottom of the limiting block 5 slopes downward from the end of the limiting block 5 away from the side wall of the buffer compartment 4. The sloped structure of the bottom of the limiting block 5 facilitates the compression of the limiting block 5 when the sample strip 3 moves upward, reducing the obstruction effect of the limiting block 5 on the upward movement of the sample strip 3.

[0050] Specifically, the buffer compartment 4 has a through hole on its side wall corresponding to the position of the limiting block 5, allowing the limiting block 5 to slide. One end of the limiting block 5 near the side wall of the buffer compartment 4 is slidably disposed within the through hole and fixed with a limiting rod 36. The limiting rod 36 is located outside the buffer compartment 4. A bracket 6 is fixed to the outer side of the side wall of the buffer compartment 4 where the limiting block 5 is located. The bracket 6 has a limiting hole for the limiting rod 36 to slide. The end of the limiting rod 36 away from the limiting block 5 slides through the limiting hole, and a limiting baffle is provided at the end of the limiting rod 36 away from the limiting block 5. A spring is sleeved on the limiting rod 36, and the spring is located between the bracket 6 and the buffer compartment 4. More specifically, each side of the buffer compartment 4 has two limiting blocks 5.

[0051] Specifically, a first photoelectric switch 31 is fixedly positioned below the buffer compartment 4 on the side furthest from the card-shifting mechanism. A first sensing element is provided on the slider connecting plate 30 for sensing in conjunction with the first photoelectric switch 31. The first photoelectric switch 31 is electrically connected to the first linear motor 29 via the main control board 2. When the first sensing element reaches the position of the first photoelectric switch 31, the first photoelectric switch 31 detects that the slider connecting plate is in place, and the first linear motor 29 stops operating.

[0052] Specifically, the card ejection mechanism includes a second linear motor 40, a card pusher block 42, a motor fixing plate 37, and an optical axis fixing plate 38. The motor fixing plate 37 is fixed on the top of the buffer compartment 4 near the card transfer mechanism, and the optical axis fixing plate 38 is fixed on the top of the buffer compartment 4 away from the card transfer mechanism. Two optical axes 39 are fixed between the optical axis fixing plate 38 and the motor fixing plate 37. The second linear motor 40 is fixed on the side of the motor fixing plate 37 near the card transfer mechanism. The lead screw of the second linear motor 40 extends through the motor fixing plate 37 toward the optical axis fixing plate 38. The nut on the lead screw of the second linear motor 40 is fixedly connected to the card pusher block 42, and the card pusher block 42 is slidably connected to the optical axis 39.

[0053] Initially, the card pusher block 42 is positioned near the motor mounting plate 37. After the reading module finishes recognizing and reading the sample strip 3, the second linear motor 40 starts rotating forward, driving the card pusher block 42 to move along the optical axis 39. The card pusher block 42 pushes the sample strip 3 towards the card outlet until the sample strip 3 is pushed out of the buffer compartment 4. After the sample strip 3 is pushed out of the buffer compartment 4, the second linear motor 40 reverses, driving the card pusher block 42 back to its original position, completing the card ejection action.

[0054] More specifically, the outer wall of the buffer compartment 4 is provided with a card dispensing plate 35, which is located below the card dispensing port. The card dispensing plate 35 is used to provide certain support and transition for the sample strips 3 that are moved out of the buffer compartment 4.

[0055] Specifically, a second photoelectric switch 41 is fixed on the motor mounting plate 37, and a second sensing part is provided on the push block 42 for cooperating with the second photoelectric switch 41 to sense. The second photoelectric switch 41 is electrically connected to the second linear motor 40 through the main control board 2. When the second sensing part reaches the position of the second photoelectric switch 41, the second photoelectric switch 41 detects that the push block 42 is in place, and the second linear motor 40 stops operating.

[0056] Specifically, the buffer compartment 4 has card limiting plates 43 on opposite sides of its top, with the card outlet located below the card limiting plates 43. The sample strips 3 inside the buffer compartment 4 are located below the card limiting plates 43. The card limiting plates 43 can limit the position of multiple sample strips 3 inside the buffer compartment 4, making the multiple sample strips 3 more stable within the buffer compartment 4.

[0057] Specifically, the interpretation module includes a fixed cover 7 and an interpretation camera 8. The fixed cover 7 is fixed to the top of the buffer compartment 4, and the interpretation camera 8 is disposed on the inner wall of the top of the fixed cover 7. The interpretation camera 8 is used to identify and process the sample strip 3.

[0058] Specifically, it also includes a main control board 2, which is electrically connected to a micro switch 44, a stepper motor 15, a reading module, a push-pull electromagnet 23, a first linear motor 29, a second linear motor 40, a first photoelectric switch 31, and a second photoelectric switch 41. The main control board 2 acquires the working information of each component and coordinates and controls the actions of each component. Using the main control board 2 to acquire and process information and control the actions of components is a conventional technique and will not be described in detail here.

[0059] Working process: In the initial state, the output end of the push-pull electromagnet 23 is in a retracted state, and both the push-card finger 22 and the pull-card finger 21 are located between the second slide plate 12 and the base plate 9. The stepper motor 15 drives the synchronous belt 16 to rotate, which in turn drives the push-pull carding mechanism to move closer to the card compartment 1 until the pull-card finger 21 is located inside the card compartment 1. The output end of the push-pull electromagnet 23 connected to the pull-card finger 21 extends, causing the push-pull block 27 of the pull-card finger 21 to extend out of the slot 24. Then, the stepper motor 15 drives the push-pull carding mechanism to move away from the card compartment 1. At this time, the push-pull block 27 on the pull-card finger 21 can pull the sample strip 3 in the card compartment 1, pulling the sample strip 3 out of the card compartment 1 and transporting it to the first slide plate 11 and the second slide plate 12. After the pull-card finger 21 moves the sample strip 3 to the desired position, the output end of the push-pull electromagnet 23 connected to the pull-card finger 21 retracts, retracting the pull-card finger 21. When there is no push-pull card mechanism, the sample strip 3 on the card transfer mechanism can be fixed on the card transfer mechanism by the pressure spring 13. Multiple sample strips 3 can be placed on the card transfer mechanism.

[0060] After the sample strip 3 on the card transfer mechanism is processed, the output end of the push-pull electromagnet 23 connected to the push-card finger 22 extends, causing the push-pull block 27 of the push-card finger 22 to extend from the slot 24. At this time, the push-pull card mechanism is driven to move towards the buffer chamber 4. The push-pull block 27 of the push-card finger 22 pushes the sample strip 3 located on the side near the buffer chamber 4, pushing the sample strip 3 to move into the buffer chamber 4.

[0061] The sample strip 3, which is moved into the cache compartment 4, moves upward under the action of the card pushing mechanism. Multiple sample strips 3 are stacked one by one in the cache compartment 4 using the card pushing and pulling mechanism and the card pushing mechanism. The judgment module identifies and judges the sample strip 3 at the top of the cache compartment 4.

[0062] Although embodiments of the present invention have been shown and described, those skilled in the art will be able to make various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
