Abstract
Description
Technical Field
[0001] This application relates to the field of information sampling and labeling technology, and more specifically to a sampling information labeling system and method. Background Technology
[0002] In biomedical, chemical analysis, and other scientific research fields, sampling tubes are crucial tools for sample collection, preservation, and analysis. As experiments expand in scale, especially in scenarios involving large-scale sample collection, researchers often face significant challenges in sample labeling, management, and identification.
[0003] Existing sampling tube labeling methods primarily rely on manual labeling. However, these methods have significant limitations in practical applications. For example, manual labeling typically involves researchers using handwritten labels to record sample information. This method is inefficient and susceptible to human error, especially when processing large batches of samples, easily leading to sample confusion, data errors, sample loss, or incomplete information. Particularly in environments involving large-scale sample processing and preservation, they often fail to provide sufficient accuracy, easily resulting in sample confusion or information loss. Furthermore, sample labeling is easily affected by human factors or external environments, posing a risk of information errors or confusion, particularly pronounced in large-scale sample collection and processing. These problems not only increase experimental time and costs but may also invalidate experimental results, severely impacting experimental reliability. Summary of the Invention

[0013] In an optional embodiment, the transfer device includes a first drive mechanism, a second drive mechanism, a mounting base, and a robotic arm. The robotic arm is mounted on the mounting base. The first drive mechanism is used to drive the mounting base away from or towards the loading frame, and simultaneously drive the robotic arm away from or towards the loading frame. The second drive mechanism is used to drive the robotic arm to release or grasp the test tube. Both the first drive mechanism and the second drive mechanism are signal-connected to the host computer.
[0014] The switching mechanism includes a third drive mechanism, which drives the loading frame to rotate around its axis and is signal-connected to the host.

[0016] In an optional embodiment, the sampling information marking system includes a base and a support arm. The loading frame and the switching mechanism are both disposed on the base. The loading frame has a mounting hole in the middle. One end of the support arm is connected to the base, and the other end passes through the mounting hole. The transfer device and the coding device are disposed on the support arm, and the coding device and the transfer device are arranged sequentially along the rotation direction of the loading frame. A plurality of receiving slots are evenly distributed around the circumference of the mounting hole.
[0017] In an optional embodiment, a human-computer interaction unit is further included. The human-computer interaction unit is connected to the host signal and is used to manually input the numbering information, and / or to display the total number of test tubes in each batch and to display the number of test tubes to be coded and the number of coded test tubes in real time.
[0018] This application provides a sampling information marking method, which employs the sampling information marking system described above, and the steps include:

[0035] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0036] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0037] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).
[0038] Unlike manual labeling, existing labeling methods include barcode labeling, embedded RFID tags, and color-coded labels. Barcode labeling, widely used for sampling tube identification to improve automation, allows for machine reading, increasing accuracy and speed. However, existing barcode labeling relies on external printers, making labels prone to detachment, damage, or contamination during operation. Long-term storage can also lead to fading and peeling, potentially resulting in the loss of critical information, making it unsuitable for long-term storage. While thermal transfer labels offer high durability, they may fade or deform in high-temperature or unsuitable humidity environments, affecting readability. Furthermore, the maintenance and consumable consumption of printing equipment increase operating costs. Embedded RFID tags are expensive and require specialized reading equipment. They may be affected by metal objects or strong magnetic fields, impacting reading accuracy. Battery life may also limit their usage time. Color-coded labels are susceptible to fading or confusion due to light, wear, or contamination. In addition, color recognition relies on human judgment, which may lead to subjective errors from different operators.
[0039] This application provides a sampling information marking system (hereinafter referred to as "marking system"), in which sample information is mainly marked on test tubes, which are containers for holding samples obtained from the subject. Of course, the marking object can also be other containers that can hold samples. For ease of description, test tubes are used as the object in the following description.
[0040] Please see Figures 1 to 4 The marking system includes a feeding device, a coding device 1, a loading device, a transfer device 3, and a main unit 5. The feeding device is used to place test tubes 4, which include test tubes to be coded and already coded test tubes. The coding device 1 is used to print the collected information sequentially onto the test tubes to be coded to generate coded test tubes. The loading device includes a loading rack 21 and a switching mechanism (not shown in the figure). The loading rack 21 is provided with multiple receiving slots 211, which are used to place test tubes to be coded and / or already coded test tubes. The switching mechanism is used to drive the loading rack 21 to move. The main unit 5 is activated so that the receiving tank 211 corresponds to the coding device 1 in sequence, and the transfer device 3 corresponds to the receiving tank 211 in sequence. The transfer device 3 is used to transfer the test tubes to be coded from the feeding device to the receiving tank 211 in sequence, and / or transfer the coded test tubes from the receiving tank 211 to the feeding device in sequence. The main unit 5 is connected to the coding device 1, the loading device and the transfer device 3 by signal. The main unit 5 completes the overall control work and is used to control the start or stop of each device, and to realize the action connection between each device in sequence.
[0041] It should be noted that the receiving slot 211 is used to place test tubes to be coded and / or coded test tubes. This can be understood as all receiving slots 211 containing test tubes to be coded, or all receiving slots 211 containing coded test tubes. It can also be understood as some receiving slots 211 containing test tubes to be coded and some containing coded test tubes. This situation may occur when removing coded test tubes after coding is completed, and it may also occur during the coding process.
[0042] Specifically, during use, the transfer device 3 sequentially transfers the test tubes to be coded from the feeding device to the loading device. Each receiving slot 211 on the loading device corresponds to a test tube 4 and can fix the test tube 4. Therefore, during the operation of the transfer device 3, the switching mechanism also synchronously drives the loading frame 21 to move, so that the transfer device 3 corresponds to the receiving slot 211 in sequence, thereby enabling the test tubes to be coded to be placed into the receiving slot 211 one by one. After the transfer device 3 has transferred the test tubes to be coded, the switching mechanism continues to drive the loading frame 21 to move so that the first test tube to be coded (which can be understood as the first test tube to be coded placed into the loading frame 21) corresponds to the coding device 1. After coding is completed, the switching mechanism continues to operate until the next test tube to be coded corresponds to the coding device 1 and completes the coding work. This cycle repeats until the last test tube to be coded is coded. At this time, the transfer device 3 and the switching mechanism continue to operate synchronously, taking out the coded test tubes one by one from the receiving slot 211 and transferring them to the feeding device.
[0043] Because there are multiple accommodating slots 211, multiple samples can be coded simultaneously, significantly improving marking efficiency. For example, with 20 slots 211, 20 samples can be coded in a single batch, increasing coding efficiency. Of course, when there are fewer than 20 samples, coding can be completed in one go. Since the coding operation is mechanized and automated, human intervention is avoided, thereby reducing the error rate, improving coding efficiency and accuracy, and enhancing the reliability of the experiment.
[0044] The feeding device can be a common test tube rack with multiple positioning holes to accommodate test tubes 4 one-to-one. Since the positioning holes on the test tube rack are generally arranged sequentially along the rack's extension direction, this rack ensures that the test tubes 4 are placed in order, preventing misalignment and ensuring accurate correspondence between the sample in each test tube and the final labeled collection information. Therefore, test tubes 4 should be placed on the test tube rack in order according to their numbering information (e.g., from smallest to largest or largest to smallest), and the transfer device 3 should also transfer them sequentially according to the placement order on the test tube rack. Because the test tube rack has limited capacity (i.e., a limited number of positioning holes), test tube racks of different capacities can be selected based on the number of test tubes 4 in each batch. After all the test tubes 4 to be coded in each batch are transferred to the loading device, the test tube rack becomes empty. After all the test tubes to be coded are coded, the empty spaces on the rack can be used to place coded test tubes in sequence, thus saving labeling costs and reducing the space occupied by the labeling system.
[0045] Of course, in other embodiments, the test tubes to be coded and the coded test tubes can also be placed on different feeding devices. That is, the feeding device can include at least a first feeding rack and a second feeding rack. The first feeding rack is used to place the test tubes to be coded, and the second feeding rack is used to place the coded test tubes. When all the test tubes to be coded in the first batch are transferred to the loading device for coding, the first feeding rack can continue to be replenished with the second batch of test tubes to be coded in sequence. And so on, to complete the coding of all sample test tubes. The whole process is automated and continuous, which can improve the efficiency and reliability of marking.
[0046] The test tube 4 has a test tube body 41 and a cap 42 for sealing the test tube 4. Since the test tube body 41 is generally made of transparent material and is usually fixed in the receiving groove 211, the coding device 1 is set facing the cap 42 for easy coding. The collected information is coded on the cap 42, which also facilitates other people to obtain and view the collected information during the subsequent placement of the test tube 4 (e.g., by scanning the code). For example, the collected information includes important information such as the subject's name, gender, age, sampling time, sample type, and disease type.
[0047] In some embodiments, the sampling information marking system further includes a number recognition device, which is used to identify the number information on the test tubes 4 to be coded. The number recognition device is connected to the host 5. To improve the marking information, number information can be set on the test tubes 4 using labels. The number recognition device can be a barcode scanner, etc., which can obtain the number information corresponding to each test tube 4 by scanning and transmit the number information to the host 5. The host 5 then retrieves the corresponding collection information or controls the start or stop of the coding device 1, loading device, and transfer device 3 based on the number information. The number recognition device can be connected to the host 5 via a data cable or wirelessly.
[0048] In other embodiments, the numbering recognition device may not be provided, and the numbering information corresponding to test tube 4 may be entered manually. Manual input can be achieved through input devices such as a mouse, keyboard, or touch screen.
[0049] In some embodiments, the sampling information marking system further includes multiple detection devices, all of which are connected to the host 5. Each receiving slot 211 has at least one detection device. These detection devices are used to detect whether a test tube 4 is present in the receiving slot 211. For example, each receiving slot 211 has a corresponding detection device. When a test tube 4 is placed into the receiving slot 211, the detection device activates once. When a test tube 4 is removed from the receiving slot 211, the detection device activates again. This activation information is transmitted to the host 5, which records the activation information and performs the next step of opening and closing based on the activation information. Specifically, the monitoring device can be a pressure sensor or an optical sensor. When a test tube 4 is placed in, the pressure sensor detects an increase in pressure, indicating that the number of test tubes 4 on the loading rack 21 has increased by one. When a test tube 4 is removed, the pressure sensor detects a decrease in pressure, indicating that the number of test tubes 4 on the loading rack 21 has decreased by one. When test tube 4 is present, the optical sensor blocks the signal as an obstruction. When test tube 4 is removed, the obstruction disappears and the signal is connected. Therefore, when there is a signal response of connection-blocking, it means that the number of test tubes 4 on the loading rack 21 increases by one, and when there is a signal response of blocking-connection, it means that the number of test tubes 4 on the loading rack 21 decreases by one.
[0050] In some embodiments, the transfer device 3 includes a first drive mechanism, a second drive mechanism, a mounting base, and a robotic arm. The robotic arm is mounted on the mounting base. The first drive mechanism drives the mounting base away from or towards the loading rack 21, and simultaneously drives the robotic arm away from or towards the loading rack 21. The second drive mechanism drives the robotic arm to release or grasp the test tube 4. Both the first and second drive mechanisms are signal-connected to the host 5. Both the first and second drive mechanisms can be drive motors, and the robotic arm can be a common three-grip robotic arm. After the marking system is started, the first drive mechanism can drive the robotic arm to the unloading device, and the second drive mechanism controls the robotic arm to grasp the test tube 4. Then, the first drive mechanism drives the robotic arm to the loading rack 21, and the second drive mechanism controls the robotic arm to release the test tube 4, completing the transfer of one test tube 4 from the unloading device into the receiving slot 211. This process is repeated to transfer all test tubes 4. Then, each test tube 4 is sequentially coded. After coding, the steps are reversed: the second drive mechanism first drives the robotic arm to grab the coded test tube from the receiving slot 211, then the first drive mechanism drives it away from the loading rack 21 and to the discharging device. The second drive mechanism then drives the robotic arm to release the coded test tube and place it on the discharging device, thus completing the transfer of test tube 4 from the receiving slot 211 to the discharging device. The use of robotic arms and other mechanized devices effectively avoids human intervention, providing convenience while reducing the risk of misoperation.
[0051] In some embodiments, whether the test tube 4 is being placed in or taken out, the first drive mechanism can drive the robot arm to complete the action of reaching the feeding device and the receiving tank 211. Therefore, the switching mechanism should also operate synchronously at this time to realize that the test tube 4 and the receiving tank 211 are placed in or taken out in a one-to-one correspondence.
[0052] The switching mechanism includes a third drive mechanism, which is used to drive the loading rack 21 to move. The third drive mechanism is connected to the host 5 by a signal. The third drive mechanism can also be a drive motor, which can drive the loading rack 21 to rotate to realize the sequential correspondence between the receiving slot 211 and the coding device 1 or the robot arm, that is, to realize the sequential correspondence between the test tube 4 and the coding device 1 or the robot arm.
[0053] In one embodiment, the third drive mechanism may also include a conveyor belt and a motor. The third drive mechanism drives the loading frame 21 to move along the travel direction of the conveyor belt, so that the robot arm and the test tube 4 correspond one-to-one. The coding device 1 can be set in the travel direction, so that when a subsequent test tube 4 to be coded is placed, the test tube 4 to be coded in front of it in the travel direction can be coded simultaneously, thereby further improving coding efficiency. At this time, there can be two transfer devices 3 along the travel direction. One is used to put the test tube 4 to be coded into the receiving slot 211, and the other is used to take out the coded test tube 4 from the receiving slot 211. The two actions can be performed simultaneously to further improve coding efficiency.
[0054] In some embodiments, the sampling information marking system includes a base 6 and a support arm 7. A loading frame 21 and a switching mechanism are both mounted on the base 6. The loading frame 21 has a mounting hole 212 in its center. One end of the support arm 7 is connected to the base 6, and the other end passes through the mounting hole 212. A transfer device 3 and a coding device 1 are mounted on the support arm 7, and the coding device 1 and transfer device 3 are sequentially arranged along the rotation direction of the loading frame 21. Multiple receiving slots 211 are evenly distributed around the circumference of the mounting hole 212. For example, in this embodiment, the loading frame 21 is a disc structure with a mounting hole 212 in the center. The receiving slots 211 are evenly distributed around the circumference of the mounting hole 212. A third driving mechanism is used to drive the loading frame 21 to rotate around its axis. Only one transfer device 3 is provided, completing the loading action at the beginning and the unloading action after coding. This ensures that the various steps do not interfere with each other and are smoothly connected. The system structure is simple and can reduce the system weight. A rational design of the marking system layout can effectively save system space and reduce the travel distance of each driving mechanism in the system, simplifying the mechanism structure.
[0055] In some embodiments, the coding device 1 includes a laser coding probe 11 and a positioning detection mechanism. The laser coding probe 11 is used to laser-code the collected information into a QR code onto the test tube to be coded. The positioning detection mechanism is electrically connected to the host 5 and is used to detect whether the test tube to be coded corresponds to the laser coding probe 11. After the test tube to be coded corresponds to the laser coding probe 11, the coding operation is performed. For example, Figure 4 As shown, the QR code is set on the cap 42 of the test tube 4. Since the cap 42 needs to be screwed tightly onto the test tube body 41 during storage and transportation, the laser engraving mode prevents ink fading and contamination, and is not affected by metal objects or strong magnetic fields, temperature and humidity, thus avoiding the problem of sample information damage. At the same time, there is no need to prepare adhesive paper or various labels for marking, effectively reducing the consumption of consumables and related costs. The positioning detection mechanism may include an infrared sensor, which can respond once when the test tube 4 corresponds to the laser marking probe 11. Alternatively, it may be a displacement sensor, which monitors the change in distance to obstacles. For example, if the height of the test tube 4 is higher than the height of the loading rack 21, when the detected distance to the obstacle is small, it indicates that the test tube 4 corresponds to the laser marking probe 11.
[0056] Since the robotic arm and coding device 1 in the marking system are mounted on the support arm 7, and according to usage habits, they are positioned above the base 6 and the loading frame 21, there may be a risk of tipping over due to the high center of gravity. To solve this problem, the bottom of the base 6 is equipped with a fixing device 9, and there are 4 of them, which are evenly distributed at the bottom of the base 6 to prevent the marking system from tipping over and shifting.
[0057] In some embodiments, a human-computer interaction unit 8 is further included. The human-computer interaction unit 8 is signal-connected to the host 5 and is used for manually inputting numbering information and / or for displaying the total number of test tubes 4 in each batch and for real-time displaying the number of test tubes to be coded and the number of coded test tubes. The human-computer interaction unit 8 includes a display screen, a keyboard, and a mouse, and together with the host 5, forms an existing computer. Without a numbering recognition device, the keyboard and mouse can preset the number of numbering information entries for a single coding operation and complete the input of the corresponding numbering information for the test tubes to be coded. The display screen can display the numbering information, the status of the entire marking process, and preset acquisition information in real time. With a numbering recognition device, the display screen can display the numbering information in real time, and the keyboard and mouse can also be used to preset the number of numbering information entries for a single batch.
[0058] For a clearer description of the technical solution of this application, please refer to [link / reference]. Figure 5 This application also provides a sampling information marking method, the steps of which include:
[0059] S101: Obtain the serial number information of the test tube to be coded;
[0060] S102: Using the transfer device 3, the test tubes to be coded are transferred one by one into the receiving tank 211 in sequence;
[0061] S103: The switching mechanism drives the loading rack 21 to move so that the test tubes to be coded correspond to the coding device 1 in sequence. The coding device 1 prints the collected information corresponding to the number information onto the corresponding test tubes to be coded to generate coded test tubes.
[0062] S104: Use transfer device 3 to transfer the coded test tubes to the discharge device in sequence.
[0063] In some embodiments, in step S101, obtaining the number information of the test tubes to be coded includes collecting the number information of multiple test tubes to be coded using a number recognition device or manually inputting the number information of multiple test tubes to be coded using a human-machine interaction device. Since the transfer device 3 picks up the test tubes to be coded from the feeding device, in step S101, the test tubes to be coded can be sequentially placed into the feeding device while the number information is being obtained in sequence, or the number information can be obtained sequentially after the test tubes are placed into the feeding device in sequence.
[0064] In some embodiments, the switch from S101 to S102 can be set to automatic. For example, the number of samples can be preset via the human-machine interaction unit 8 before step S101. When the number of acquired numbering information matches the preset number of samples, S102 starts automatically. Of course, the switch from S101 to S102 can also be manual. For example, after the numbering information is acquired, the start button can be clicked on the human-machine interaction unit 8 to start S102 and subsequent steps. However, this method has certain limitations. The number of test tubes to be coded should not exceed the number of accommodating slots 211. All sample test tubes can be coded at once. The program for preset sample number and the program for comparing the preset sample number with the number of numbering information can be omitted from the system, which can reduce the complexity of the system.
[0065] When the number of test tubes to be coded exceeds the number of accommodating slots 211, the test tubes can be processed in batches. After completing the coding of a single batch, the experimenter repeats steps S101-S104 to complete the coding of all test tubes 4. Before each coding, the quantity of samples in a single batch and the numbering information of the test tubes 4 need to be preset separately. For example, in this experiment, the experimenter collected 100 samples and put them into 100 test tubes 4. The single capacity of the loading rack 21 is 20. Therefore, the 100 samples are divided into 5 batches for coding. The numbering information needs to be obtained when coding each batch to provide a basis for subsequent steps.
[0066] Of course, to save steps, the numbering information of all samples (e.g., 100) can be collected first, then the maximum number of samples to be coded in a single batch (i.e., the number of accommodating slots 211) can be preset, and then steps S102-S104 can be performed to complete the coding of a single batch of test tubes 4. After that, steps S102 to S104 can be repeated until all samples are coded. In order to deal with the situation that the number of samples in each batch is different in the same experiment, the number of samples to be coded in a single batch can be preset before coding each batch.
[0067] In one embodiment, after the numbering information is collected or input, the host 5 controls the transfer device 3 to perform a feeding action and controls the switching mechanism to transfer the test tubes to be coded one by one into the receiving tank 211 in sequence; the host 5 can obtain the first number of feeding actions of the transfer device 3, and control whether the switching mechanism and the coding device 1 operate according to the first number of actions information. When the first number of actions information is consistent with the number of numbering information (or the number of samples preset in a single batch), the host 5 controls the switching mechanism and the coding device 1 to operate alternately in sequence until all the test tubes to be coded are generated as coded test tubes; the host 5 can obtain the cutting... The host 5 obtains the second action count information of the switching mechanism and / or the third action count information of the coding device 1, and controls whether the transfer device 3 performs a material picking action based on the second action count information and / or the third action count information. When the number of the second action count information and / or the third action count information matches the number of the numbered information, the host 5 controls the transfer device 3 to transfer the coded test tubes to the discharging device in sequence. The host 5 can also obtain the fourth action count information of the transfer device 3 picking up materials, and control whether the transfer device 3 continues to pick up materials based on the fourth action count information. When the number of the fourth action count information matches the number of the numbered information, the host 5 controls the transfer device 3 to shut down.
[0068] In another embodiment, after the numbering information is collected or input, the host 5 controls the transfer device 3 to perform a feeding action, so as to transfer the test tubes to be coded one by one into the receiving tank 211 in sequence; the host 5 can obtain the first detection information of the detection device, and control whether the switching mechanism and the coding device 1 operate according to the first detection information. When the number of the first detection information and the numbering information (or the number of samples preset in a single batch) are consistent, the host 5 controls the switching mechanism and the coding device 1 to operate alternately in sequence until all the test tubes 4 to be coded are generated as coded test tubes 4; the host 5 can obtain the switching mechanism's... The host 5 obtains the second action count information and / or the third action count information of the coding device 1, and controls whether the transfer device 3 performs the material picking action based on the second action count information and / or the third action count information. When the number of the second action count information and / or the third action count information matches the number information, the host 5 controls the transfer device 3 to transfer the coded test tubes 4 to the discharging device in sequence. The host 5 can also obtain the second detection information of the detection device, and control whether the transfer device 3 continues the material picking action based on the second detection information. When the number of the second detection information matches the number information, the host 5 controls the transfer device 3 to shut down.
[0069] Of course, in some embodiments, when the switching mechanism and coding device 1 are started after the material feeding is completed, the first action information and the first detection information can be combined for judgment. The switching mechanism and coding device 1 are only started when both of them match the number information. When picking up the material, the fourth action information and the second detection information are combined for judgment. The switching mechanism and coding device 1 are only turned off when both of them match the number information. Judging by the sum of the two pieces of information can improve the accuracy of the judgment in the whole device and avoid false starts that may affect the accuracy and reliability of the final coding.
[0070] Since the switching mechanism is active during the material feeding, coding, and code retrieval processes throughout the entire marking system startup, to avoid inaccurate switching mechanism action information affecting subsequent actions, the completion of coding can be directly determined by the number of actions and numbering information of the coding device 1. For example, this can be determined by the number of actions of the laser coding probe 11 or the number of actions of the positioning detection mechanism.
[0071] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
