This process is not only time-consuming and labor-intensive, but also highly susceptible to human factors such as operator fatigue, lack of concentration, or differences in skill levels, leading to frequent problems such as sample diversion errors and misidentification errors. These issues not only extend the sample testing cycle and affect the timeliness of clinical diagnosis, but can also lead to quality accidents due to human operational errors, posing unnecessary risks to patients and even exposing medical institutions to legal risks.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please refer to Figure 1 - Figure 9 , an automatic sample diversion device for a laboratory, comprising:

[0041] The first conveying mechanism 1 includes two first side plates 8, and a first conveying belt 9 is provided on the inner side of the two first side plates 8. First conveying rollers 10 are provided at the positions of both ends of the inner side of the first conveying belt 9. The first conveying rollers 10 are rotatably connected to the first side plates 8. A first driving motor 11 is provided on the outer side of the first side plate 8 and at the position of one of the first conveying rollers 10. The output end of the first driving motor 11 is connected to the first conveying roller 10 at the corresponding position; a limiting plate group 3 is provided above the first conveying mechanism 1; the sample is conveyed by the first conveying mechanism 1, and the first conveying roller 10 is driven to rotate by starting the first driving motor 11, so that the first conveying belt 9 is driven to move synchronously by the rotating first conveying roller 10. After the sample is placed on the upper end of the first conveying belt 9, the sample is conveyed. The sample conveyed by the first conveying belt 9 can be guided and limited by the limiting plate group 3.

[0042] Specifically, the limiting plate group 3 includes limiting baffles 12 and guiding baffles 13. Limiting baffles 12 are provided on both sides of the first conveying mechanism 1 along the length direction. The limiting baffles 12 on both sides of the first conveying mechanism 1 are symmetrically arranged. Two guiding baffles 13 are provided near the end of the first conveying mechanism 1. The two guiding baffles 13 are symmetrically arranged and funnel-shaped, with the narrower ends of the two guiding baffles 13 corresponding to the ends of the first transfer mechanism 4. The limiting baffles 12 can prevent samples conveyed by the first conveying mechanism 1 from falling, and the guiding baffles 13 can gather the samples toward the center.

[0043] The second conveying mechanism 2 is arranged at one end of the first conveying mechanism 1, and the second conveying mechanism 2 includes two second side plates 14, a support plate 15 is fixedly connected between the two second side plates 14, a rotating conveying assembly 16 is provided at one end between the two second side plates 14, and a second conveyor belt 17 is provided at the other end between the two second side plates 14, and the upper ends of the rotating conveying assembly 16 and the second conveyor belt 17 are both located outside the upper end of the support plate 15;

[0044] A first transfer mechanism 4, a visual recognition mechanism 5, a second transfer mechanism 6, and an automatic diverting mechanism 7 are sequentially arranged from one end to the other end above the second conveying mechanism 2. One end of the first transfer mechanism 4 is fixedly connected to the first conveying mechanism 1, and the other end of the first transfer mechanism 4 is fixedly connected to the second conveying mechanism 2. One end of the rotating conveying assembly 16 is located at the end of the first transfer mechanism 4. The position of the visual recognition mechanism 5 corresponds to the position of the rotating conveying assembly 16. The second transfer mechanism 6 is located between the rotating conveying assembly 16 and the second conveyor belt 17. The other end of the rotating conveying assembly 16 is located at one end of the second transfer mechanism 6. One end of the second conveyor belt 17 is located at the other end of the second transfer mechanism 6. The automatic diverting mechanism 7 is located above the second conveyor belt 17.

[0045] The first transfer mechanism 4 is used for transporting samples between the first conveying mechanism 1 and the rotating conveying assembly 16 , and the second transfer mechanism 6 is used for transporting samples between the rotating conveying assembly 16 and the second conveyor belt 17 ;

[0046] The visual recognition mechanism 5 is used to collect image information of the sample and transmit the collected image information to the host computer;

[0047] The automatic diversion mechanism 7 is used to receive instructions from the host computer to divert samples.

[0048] It can be seen that after the sample transported by the first conveying mechanism 1 is transported to the upper end of the second conveying mechanism 2, the sample can be transported to the top of the rotating conveying component 16 through the first transfer mechanism 4. The rotating conveying component 16 can realize the rotation effect while transporting the sample, so that the visual recognition mechanism 5 can perform all-round image collection of the sample side and upload it to the host computer. The sample is transferred from the rotating conveying component 16 to the top of the second conveyor belt 17 through the second transfer mechanism 6. The host computer sends a diversion instruction to the automatic diversion mechanism 7 after processing and comparison based on the image information collected by the visual recognition mechanism 5. The automatic diversion mechanism 7 receives the diversion instruction and diverts the sample.

[0049] Specifically, the rotating conveying assembly 16 includes two second conveying rollers 36, one of the second conveying rollers 36 is located below the end of the first transfer mechanism 4, and the other second conveying roller 36 is located below the end of the automatic diversion mechanism 7. The two second conveying rollers 36 are both rotatably connected to the second side plate 14, and the two second conveying rollers 36 are rotatably connected to the second drive wheel 37 and the third drive wheel 38. The two second drive wheels 37 are connected by a third conveyor belt 39, and the two third drive wheels 38 are connected by a fourth conveyor belt 40. An opposing drive structure 41 is provided below one of the second conveying rollers 36, and the opposing drive structure 41 is used for the opposing rotation of the second drive wheel 37 and the third drive wheel 38.

[0050] The second drive wheel 37 and the third drive wheel 38 are driven to rotate in relative directions by the counter-driving structure 41, so that the movement directions of the third conveyor belt 39 and the fourth conveyor belt 40 are opposite. After the sample moves to the upper end of the rotating conveying assembly 16, the rotation effect of the sample is achieved by the counter-moving third conveyor belt 39 and the fourth conveyor belt 40. By making the movement speeds of the third conveyor belt 39 and the fourth conveyor belt 40 different (the movement speed consistent with the movement direction of the second conveyor belt 17 is higher), the rotating conveying assembly 16 can achieve the effect of sample transportation while realizing sample rotation.

[0051] Example 2:

[0052] The automatic sample diversion device for the laboratory provided in Example 1 is further optimized. Specifically, Figure 4-Figure 5 As shown, the first transfer mechanism 4 has the same structure as the second transfer mechanism 6. The first transfer mechanism 4 includes two symmetrically arranged first limit frames 18. The rotating conveying assembly 16 is located between the two first limit frames 18. A movable push frame 19 is provided on the first limit frame 18. One side of the movable push frame 19 extends to the position between the two first limit frames 18. A fixed plate 20 is provided on the other side of the movable push frame 19. The fixed plate 20 is fixedly connected to the first limit frame 18 on the same side, and the movable push frame 19 is fixedly connected to the fixed plate 20 on one side. It is connected to a guide plug plate 21 and a guide plug rod 22, which are both plugged into the fixed plate 20 on the same side. A thrust spring 23 is provided between the movable push frame 19 and the fixed plate 20 on the same side, and the thrust spring 23 is sleeved on the outside of the guide plug rod 22; the first limit frame plate 18 is above and at the end position and is rotatably connected to the first drive wheel 24, one of the first drive wheels 24 is driven by a motor, and the two first drive wheels 24 are connected by a first transmission belt 25, and the movable push frame 19 is located at the inner side of the first transmission belt 25.

[0053] Through the above-mentioned structural design, the rotation of the first driving wheel 24 can drive the first transmission belt 25 to move synchronously, and the movable push frame 19 can guide one side of the first transmission belt 25 to the position inside the two first limiting frames 18. After the sample enters the two first limiting frames 18, the two moving first transmission belts 25 can drive the sample to move, and the thrust applied to the movable push frame 19 by the thrust spring 23 can ensure that the first transmission belt 25 and the sample remain in contact.

[0054] Example 3:

[0055] The automatic sample diversion device for the laboratory provided in Example 1 is further optimized. Specifically, Figure 6 As shown, the visual recognition mechanism 5 includes two symmetrically arranged second limit frames 26, and the rotating conveying assembly 16 is located between the two second limit frames 26. A high-definition camera 27 is arranged above one of the second limit frames 26, and the high-definition camera 27 is fixedly connected to the second limit frame 26 through an adjustable bracket 28.

[0056] Through the above-mentioned structural design, while the rotating conveying assembly 16 drives the sample to rotate and convey, the second limiting frame 26 guides and limits the sample, the high-definition camera 27 is used to collect image information, and the high-definition camera 27 is fixed and the angle is adjusted by the adjustable bracket 28.

[0057] Example 4:

[0058] The automatic sample diversion device for the laboratory provided in Example 1 is further optimized. Specifically, Figure 7-Figure 8 As shown, the automatic diversion mechanism 7 includes a third limiting frame 29, one end of the third limiting frame 29 is provided with a diversion introduction groove 30, the end of the rotating conveying assembly 16 corresponds to the position of the diversion introduction groove 30, and the other side of the third limiting frame 29 is provided with a diversion isolation frame 31, the lower end of the diversion isolation frame 31 is provided with multiple diversion channels, a diversion pushing wheel 33 is provided between the diversion introduction groove 30 and the diversion isolation frame 31, and a diversion pushing groove 34 is provided below the diversion pushing wheel 33, and the diversion pushing groove 34 corresponds to the position of the diversion introduction groove 30, a second drive motor 35 is fixedly connected to the top of the diversion isolation frame 31, and the output end of the second drive motor 35 is connected to the diversion pushing wheel 33, and the rear end of the third limiting frame 29 is fixedly connected with a diversion protection side plate 32.

[0059] Through the above-mentioned structural design, the sample enters the diversion introduction groove 30 after being transported by the second transport mechanism 6, and is continuously transported by the second conveyor belt 17. After the sample enters the diversion push groove 34 below the diversion push wheel 33, the second conveyor belt 17 stops moving or reduces the movement speed, and controls the second drive motor 35 to drive the diversion push wheel 33 to rotate according to the received diversion instruction, and pushes the sample to the corresponding diversion channel through the diversion push groove 34. When diversion is not required, the diversion push wheel 33 remains stationary, so that the sample can directly enter the diversion channel behind through the diversion push groove 34.

[0060] Example 5:

[0061] The automatic sample diversion device for the laboratory provided in Example 1 is further optimized. Specifically, Figures 9-11 As shown, the opposing drive structure 41 includes a mounting plate 46, both ends of the mounting plate 46 are fixedly connected to the second side plate 14 at the same end, and the mounting plate 46 is rotatably connected to the position near the two ends. The two drive rods 44 are connected by a chain 45, and the drive rods 44 are provided with sprockets at the positions of the chain 45. The lower end of the mounting plate 46 is fixedly connected to the third drive motor 47, and the output end of the third drive motor 47 is connected to one of the drive rods 44. The upper ends of the drive rods 44 are fixedly connected to the drive bevel gear 43, and the second drive wheel 37 and the third drive wheel 38 are fixedly connected to the side away from each other with a follower bevel gear 42, and the follower bevel gear 42 is meshed with the corresponding drive bevel gear 43.

[0062] It can be seen that by starting the third drive motor 47, one drive rod 44 can be driven to rotate, and the other drive rod 44 can be driven to rotate synchronously through the chain 45. The driving bevel gear 43 is meshed with the follower bevel gear 42, so that when the drive rod 44 rotates, the follower bevel gear 42 can drive the connected second drive wheel 37 and the third drive wheel 38 to rotate, and the follower bevel gears 42 on both sides of the second drive wheel 37 and the third drive wheel 38 are arranged in opposite directions. Therefore, when the driving bevel gear 43 rotates in the same direction, the two follower bevel gears 42 rotate in opposite directions. Therefore, the second drive wheel 37 and the third drive wheel 38 drive the third conveyor belt 39 and the fourth conveyor belt 40 to move in relative directions. By using follower bevel gears 42 of different models or diameters on the sides of the second drive wheel 37 and the third drive wheel 38, the effect of different movement speeds of the third conveyor belt 39 and the fourth conveyor belt 40 can be achieved.

[0063] Furthermore, three mounting grooves 48 are provided on the inner side of the second side panel 14 along the length direction, wherein two of the mounting grooves 48 are slidably connected to mounting slider 1 49, and another mounting groove 48 is slidably connected to mounting slider 2 50. A bearing seat 51 is provided at the end of the second conveyor roller 36, and the end angle positions of the bearing seat 51 are fixedly connected to the mounting slider 1 49 by screws, and the end of the mounting plate 46 is fixedly connected to the mounting slider 2 50 by screws.

[0064] Through the above-mentioned structural design, when the screws are tightened, the friction between the chain 45, the mounting slider 1 49 and the mounting slide groove 48 is large, which can realize the installation and fixation of the mounting plate 46, the second conveyor roller 36, and the mounting plate 46. When the rotating conveying assembly 16 needs to be replaced or maintained, the screws can be loosened to allow the mounting slider 1 49 and the mounting slider 2 50 to slide in the corresponding mounting slide groove 48, thereby adjusting the position of the second conveyor roller 36 and the mounting plate 46, thereby facilitating the maintenance of the device.
