Description

Technical Field

[0001] This utility model belongs to the field of sorting equipment technology, and specifically relates to a sample sorting device with a multi-classification structure. Background Technology

[0002] Many devices struggle to meet the demands of large-scale, multi-class sample processing, especially during pandemics or periods of surging sample volumes. This bottleneck in sorting speed can severely impact subsequent testing procedures, leading to delays in results. Existing devices also lack flexibility, making it difficult to adapt to different types of sampling tubes and sorting requirements.

[0003] Conventional approaches include: employing more efficient sorting technologies, such as high-speed cameras and machine vision, to improve sorting speed and accuracy; improving recognition algorithms, such as using advanced algorithms like deep learning, to enhance the ability to identify complex samples; designing more flexible sorting devices, such as using modular designs, to facilitate adjustments based on different needs; and establishing a standardized system for sampling tubes, unifying specifications and label formats to simplify the sorting process. However, these methods also have drawbacks: efficient sorting technologies are costly, increasing equipment investment costs; training advanced algorithms requires a large amount of data, necessitating significant time and effort; designing and manufacturing flexible sorting devices is challenging, increasing R&D costs; and establishing a standardized system requires collaborative efforts from all parties and a lengthy development cycle. Therefore, we aim to design a sample sorting device with a novel structure to address this problem. Utility Model Content

The conveying component for equidistant conveying of different sampling tubes is installed inside the lower side of the sorting device body. A sorting component based on mechanical vision for classifying and sorting the sampling tubes on the conveying component is installed on the upper left and upper right sides of the sorting device body, respectively.

[0006] The sorting device body is equipped with two vision components for classification and identification. The left and right rear sides of the conveying component are respectively equipped with an infrared sensor for detecting the position of the collection tube. The lower end of the sorting component is movably equipped with a flexible gripper for gripping the collection tube.

[0007] In a preferred embodiment, the sorting device body includes a housing, a storage box, an operation display screen, and a vision component. Multiple storage boxes for collecting the sorted collection tubes are movably hung on the lower side of the front surface of the housing.

[0008] In a preferred embodiment, the upper surface of the front surface of the housing has multiple sorting windows for sorting collection tubes from left to right. An operation display screen for setting the working program of the equipment is installed on the upper left rear side of the housing. A control circuit board is installed inside the upper end of the housing. In actual use, the inner end of the sorting window is close to the front side of the conveyor belt body, and has vertical baffles of not less than 5cm high on its rear, left and right sides.

[0009] In a preferred embodiment, a vision component is installed on the left rear side and the right rear side inside the housing.

In actual use, the vision camera, in conjunction with an infrared sensor, enables the sorting component to accurately identify the corresponding collection tube and transmit the detected information to the control module on the control circuit board located inside the upper side of the housing. Then, the drive module on the sorting component is controlled by a relay to drive the flexible gripper to grab the corresponding collection tube and place it in the sorting window of its category, thereby achieving the purpose of sorting.

[0012] In a preferred embodiment, the sorting assembly includes a flexible gripper, a pull rod, a drive module, and a mounting plate. The lower surface of the mounting plate is equilaterally triangularly mounted with three drive modules. The upper end of the mounting plate is fixedly connected to the top of the outer casing via a corner plate, and the mounting plate is positioned directly above the conveyor belt body. The drive module is a servo electric cylinder. In actual use, each sorting assembly corresponds to four sorting windows, that is, to four types of sorting tubes, which can effectively sort multiple types of sorting tubes.

[0013] In a preferred embodiment, the outer end of each drive module is hinged to the upper end of two pull rods, and the lower ends of the two pull rods used for adjusting the position of the flexible gripper are hinged to both sides of the corner of the upper end of the flexible gripper.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: by setting multiple sorting windows on the front side of the outer shell and installing storage boxes in a number corresponding to the number of sorting windows, it is possible to handle a large number of collection tube sorting work when necessary, and provide multiple classification options, so as to classify and sort multiple collection tubes in more detail.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a sample sorting device with a multi-classification structure, including: a sorting device body 100, a conveying component 200 and a sorting component 300. The conveying component 200 for equidistant conveying of different sampling tubes is installed on the lower side inside the sorting device body 100. A sorting component 300 based on machine vision for classifying and sorting the sampling tubes on the conveying component 200 is installed on the upper left and upper right sides inside the sorting device body 100.

[0027] The sorting device body 100 has two vision components 160 installed inside for classification and identification. The conveying component 200 has an infrared sensor 220 installed on the left rear side and right rear side for detecting the position of the collection tube. The sorting component 300 has a flexible gripper 310 movably installed at the lower end for gripping the collection tube.

[0028] Please see Figure 1 , Figure 5 The sorting device body 100 includes a housing 110, a storage box 120, an operation display screen 140, and a vision component 160. Multiple storage boxes 120 for collecting sorted collection tubes are movably hung on the lower side of the front surface of the housing 110.

[0029] Multiple sorting windows 130 for sorting collection tubes are provided on the upper side of the front surface of the housing 110 from left to right. An operation display screen 140 for setting the working program of the equipment is installed on the upper left rear side of the housing 110. A control circuit board is installed inside the upper end of the housing 110. In actual use, the inner end of the sorting window 130 is close to the front side of the conveyor belt body 210, and has vertical baffles of not less than 5cm high on its rear, left and right sides.

[0030] As the first embodiment of this utility model, multiple sorting windows 130 are provided on the front side of the outer shell 110, and storage boxes 120 corresponding to the number of sorting windows 130 are installed. In actual use, one sorting window 130 corresponds to one storage box 120. When the sorting component 300 picks up the collection tube of the corresponding category and places it in the sorting window 130 of the required classification area, the collection tube automatically slides down the sorting window 130 to the storage box 120 below it for temporary storage. Multiple sorting windows 130 and multiple storage boxes 120 are combined with the dual sorting component 300, which can handle a large number of collection tube sorting tasks when necessary and provide multiple classification options, allowing for more detailed classification and sorting of various collection tubes.

[0031] Please see Figures 1 to 4 Inside the housing 110, a vision component 160 is installed on the left rear side and the right rear side respectively. The vision component 160 includes a mounting bracket and a vision camera. In actual use, the vision camera, together with the infrared sensor 220, enables the sorting component 300 to accurately identify the corresponding collection tube and transmit the detected information to the control module on the control circuit board located inside the upper side of the housing 110. Then, through the relay control, the drive module 330 on the sorting component 300 drives the flexible gripper 310 to grab the corresponding collection tube and place it in the sorting window 130 of the corresponding category, thereby achieving the purpose of sorting.

[0032] A vision camera for visual inspection of the acquisition tube conveyed on the upper side of the mounting bracket is installed on the lower side of the mounting bracket near the conveying component 200, and an inspection port 150 is provided on the upper end of the housing 110.

[0033] The conveying assembly 200 includes a conveyor belt body 210 and an infrared sensor 220. An infrared sensor 220 for detecting objects is installed on the left rear side and the right rear side of the conveyor belt body 210.

[0034] The sorting component 300 includes a flexible gripper 310, a pull rod 320, a drive module 330, and a mounting plate 340. The lower surface of the mounting plate 340 is equilaterally triangular and has three drive modules 330 mounted on it. The upper end of the mounting plate 340 is fixedly connected to the top of the outer casing 110 through a corner plate, and the mounting plate 340 is positioned directly above the conveyor belt body 210. The drive module 330 is a servo electric cylinder. In actual use, each sorting component 300 corresponds to four sorting windows 130, that is, to four types of sorting tubes, which can effectively sort multiple types of sorting tubes.

[0035] Each drive module 330 has its outer end hinged to the upper end of two pull rods 320, and the lower ends of the two pull rods 320 used to adjust the position of the flexible gripper 310 are hinged to both sides of the upper corner of the flexible gripper 310.

[0036] As a second embodiment of this utility model, based on the first embodiment described above, by setting up a conveying component 200 and a sorting component 300, in conjunction with a vision component 160, in actual use, when an external feeding device distributes various mixed collection tubes at equal intervals on the conveyor belt body 210, when the collection tube reaches the first vision component 160, the vision component 160 determines whether the collection tube belongs to the items of the first four sorting windows 130 and determines which specific sorting window 130 it belongs to (this can be determined by the appearance and color of the collection tube; if it is determined by a label, a machine vision-based flipping structure needs to be configured to flip the label of the collection tube on the conveyor belt body 210 so that it faces upwards; the machine vision-based flipping structure can adopt the existing product structure on the market).

[0037] If the tube belongs to the first four sorting windows, the front sorting component 300 is activated and, in conjunction with the front infrared sensor 220, grips the selected tube. Simultaneously, the corresponding drive module 330 is controlled to move the flexible gripper 310 at the lower end of the sorting component 300 carrying the tube to the designated sorting window 130, where the tube is placed. If the tube does not belong to the first four sorting windows 130, the rear sorting component 300 is activated and, in conjunction with the rear infrared sensor 220, grips the selected tube when it moves to the rear vision component 160. Simultaneously, the corresponding drive module 330 is controlled to move the flexible gripper 310 at the lower end of the sorting component 300 carrying the tube to the designated sorting window 130 among the last four, where the tube is placed. The dual sorting components 300 can process a large number of tubes simultaneously, giving the equipment the capacity to process a large number of tubes and to sort tubes of various categories.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
