Description

Technical Field

[0001] This utility model relates to the field of medical testing automation technology, and more specifically, to an automatic single-machine sample injection device. Background Technology

[0002] With the development of automated medical testing, automated sample loading and unloading can now be achieved. However, in existing technologies, multi-channel loading is not possible; samples can only be loaded and unloaded sequentially according to their arrangement in the sample tray. For special cases, such as samples requiring expedited testing, priority loading and unloading cannot be implemented, resulting in special samples not being prioritized for testing. This leads to insufficient flexibility. Furthermore, when a single sample is missed during loading and unloading, the machine can only be stopped for manual correction of the testing information. It cannot automatically identify missed samples, and these missed samples cannot re-enter the testing cycle, affecting the testing process.

[0003] In summary, how to solve the problems of low flexibility, inability to handle multiple sample inputs and outputs, and inability to meet the urgent testing needs of special samples in existing equipment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automatic single-machine sample feeding device, which sets up several sets of parallel sample trays and uses a three-axis gripper to pick up and drop samples, realizing multi-channel sample input and output, and solving the problem of urgent special samples; at the same time, a sample recognition component is set at the sample input and output blocking position to identify sample information. For missed samples, they can be automatically incorporated into the inspection cycle without manual intervention and without affecting the inspection process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated single-unit sample injection device includes:

[0007] A track assembly for unidirectional and active sample transport. The track assembly is provided with a first blocking position and a third blocking position in sequence along the transport direction. An interception component and a sample recognition component are provided at both the first blocking position and the third blocking position. The interception component is used to control the passage or interception of the sample passing through the corresponding blocking position. The sample recognition component is used to identify the sample information at the corresponding blocking position.

[0008] The pusher operation module has several sets of sample trays arranged in parallel inside, and the sample trays are used to hold the samples;

[0009] The three-axis gripper has a working area covering the first blocking position, the third blocking position, and the pusher operation module, and is used to grasp the sample and transfer it within the sample tray in the first blocking position, the third blocking position, and the pusher operation module.

[0010] Preferably, a blocking sensor is provided at the downstream end of the first blocking position and / or the third blocking position to detect whether sample accumulation occurs downstream of the corresponding blocking position.

[0011] Preferably, a second blocking position is provided between the first blocking position and the third blocking position, and the interception component is provided at the second blocking position. When the sample is present in the third blocking position, the interception component at the second blocking position is in an interception state.

[0012] Preferably, the interception assembly includes two sets of blocking rods and an interception drive assembly for driving the blocking rods to move. The two sets of blocking rods are arranged along the feed direction of the track assembly, and only one set of the sample can be accommodated between the two sets of blocking rods.

[0013] Preferably, the interception drive assembly includes an interception drive motor and a gear disposed at the output shaft end of the interception drive motor;

[0014] The blocking rod is slidably installed perpendicular to the track assembly, and a rack that meshes with the gear is fixedly provided inside the blocking rod;

[0015] The racks of the two sets of blocking rods are located on both sides of the gear, and when the gear rotates, the two sets of blocking rods move in opposite directions.

[0016] Preferably, the interception assembly further includes two sets of interception positioning sensors. When the blocking rod moves to the interception position, the corresponding interception positioning sensor triggers feedback.

[0017] Preferably, the sample identification component includes an RFID identification component and / or a barcode identification component, used for identifying RFID information within the sample and / or identifying barcode information of the sample.

[0018] Preferably, the sample recognition component further includes a rotating component, which includes a synchronous belt, a driven wheel, and a recognition drive component that drives the synchronous belt to rotate, distributed on both sides of the track component. The synchronous belt is used to contact the sample and drive the sample to rotate, and the driven wheel is used to abut against the sample, thereby suppressing radial displacement of the sample.

[0019] Preferably, the track assembly is provided with a plurality of sets of follow-up sample components, the sample components being used to hold the sample;

By setting up several sets of sample trays in parallel within the pusher operation module to accommodate samples, and using a three-axis gripper for sample loading and unloading, it is possible to use a single sample tray as a channel for alternating loading and unloading of samples from multiple channels. For example, if urgent samples are placed in a separate sample tray, they will be loaded first from the urgent sample tray, thus prioritizing the detection of urgent samples and improving the flexibility of the equipment.

[0025] 2. By setting multiple blocking positions within the track assembly, samples are intercepted, facilitating sample gripping by the three-axis gripper. Sample recognition components are also installed at the blocking positions to identify sample information and determine whether a sample has been removed. This allows for the re-inspection of missed samples, achieving automated sample entry and exit without manual intervention and avoiding disruption to the inspection process.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0044] The core of this utility model is to provide an automatic single-machine sample feeding device. By setting up several sets of parallel sample trays and using a three-axis gripper to pick up and drop samples, it realizes multi-channel sample input and output, solving the problem of urgent special samples. At the same time, a sample recognition component is set at the sample input and output blocking position to identify sample information. For missed samples, they can be automatically incorporated into the inspection cycle without manual intervention and without affecting the inspection process.

[0045] Please refer to Figures 1-5 An automatic single-unit sample injection device, comprising:

[0046] The track assembly 500 is used for unidirectional and active sample transport. The track assembly 500 is provided with a first blocking position 700 and a third blocking position 900 in sequence along the transport direction. An interception component 950 and a sample recognition component are provided at both the first blocking position 700 and the third blocking position 900. The interception component 950 is used to control the passage or interception of samples passing through the corresponding blocking position, and the sample recognition component is used to identify the sample information of the corresponding blocking position.

[0047] The pusher operation module 200 has several sets of sample trays 400 arranged in parallel inside, which are used to hold samples;

[0048] The three-axis gripper 600 has a working area covering the first blocking position 700, the third blocking position 900 and the pusher operation module 200, and is used to grasp samples and transfer them to the sample tray 400 within the first blocking position 700, the third blocking position 900 and the pusher operation module 200.

[0049] like Figure 1 As shown, a first blocking position 700 and a third blocking position 900 are sequentially arranged along the feeding direction within the track assembly 500. The first blocking position 700 is the sample exit position, and the third blocking position 900 is the sample entry position. When the sample reaches the first blocking position 700, the sample recognition component recognizes the sample information. If the recognition information indicates that the sample has completed the inspection and meets the sample exit requirements, the three-axis gripper 600 is controlled to grip the sample at the first blocking position 700 for sample exit and place it in the corresponding sample tray 400. If the recognition information indicates that the sample has not completed the inspection or does not meet the sample exit requirements, the interception component 950 within the first blocking position 700 is controlled to release the sample, allowing it to re-enter the inspection process.

[0050] Within the third blocking position 900, the three-axis gripper 600 picks up the sample in the sample tray 400 and moves it to the third blocking position 900. The sample recognition component identifies the sample information and records the sample's injection channel, and then releases it, allowing the sample to enter the inspection cycle.

[0051] When a sample that does not meet the sampling requirements is inspected at the first blocking position 700 and passes through the third blocking position 900, the interception component 950 in the third blocking position 900 directly allows it to pass.

[0052] Meanwhile, several independent sample trays 400 are arranged in parallel within the pusher operation module 200. Each sample tray 400 is used as a single channel for sample arrangement, while the working area of ​​the three-axis gripper 600 covers all sample trays 400. Therefore, it can selectively inject samples through multiple channels. Combined with the information recognition of the sample recognition component in the blocking position, it can selectively eject samples to meet the urgent testing needs of special samples.

[0053] In some embodiments, a blocking sensor is provided at the downstream end of the first blocking position 700 and / or the third blocking position 900 to detect whether sample accumulation occurs downstream of the corresponding blocking position.

[0054] In the actual testing process, the track assembly 500 is equipped with several sets of sample assemblies 510 that can move to carry the sample. When the sample is discharged, the sample assemblies 510 that do not carry the sample still move with the track assembly 500. Therefore, there is a situation where the sample assemblies 510 are congested downstream of the first blocking position 700.

[0055] Therefore, a first blocking sensor 710 is set downstream of the first blocking position 700. When the first blocking sensor 710 is triggered, it indicates that there is a congestion of sample component 510 downstream of the first blocking position 700. At this time, the interception component 950 in the first blocking position 700 is controlled to be in the interception state to intercept the upstream sample component 510 and sample, so as to avoid a large number of sample components 510 or samples accumulating at the third blocking position 900 and reduce the impact on sample introduction.

[0056] Meanwhile, a third blocking sensor 910 is set downstream of the third blocking position 900. When the third blocking sensor 910 is triggered, if there is a sample assembly 510 or sample accumulation downstream of the third blocking position 900, the triaxial gripper 600 is controlled to stop the sample feeding to relieve the pressure on the testing equipment.

[0057] In some embodiments, a second blocking position 800 is provided between the first blocking position 700 and the third blocking position 900, and an interception component 950 is provided at the second blocking position 800. When a sample exists in the third blocking position 900, the interception component 950 at the second blocking position 800 is in an interception state.

[0058] A second blocking position 800 is added between the first blocking position 700 and the third blocking position 900 to intercept the sample component 510 or sample passing through the first blocking position 700, so as to avoid multiple sample components 510 from gathering at the third blocking position 900 and affecting the sample introduction.

[0059] In some embodiments, the interception assembly 950 includes two sets of blocking rods 951 and an interception drive assembly for driving the blocking rods 951 to move. The two sets of blocking rods 951 are arranged along the feed direction of the track assembly 500, and only one set of samples can be accommodated between the two sets of blocking rods 951.

[0060] like Figure 3 As shown, the interception component 950 uses two sets of blocking bars 951 to intercept the sample component 510 or the sample. Only one sample component 510 or sample can be accommodated between the two sets of blocking bars 951. At this time, the two sets of sample components 510 are alternately in the interception state, which can realize that only one sample component 510 or sample can pass through at a time. This allows for precise control of the release speed of the sample component 510 or sample, and ensures that the position of the sample component 510 or sample within the blocking position is fixed, which is convenient for the three-axis gripper 600 to grasp the sample and ensure the success rate of sample entry and exit.

[0061] In some embodiments, the interception drive assembly includes an interception drive motor and a gear 953 disposed at the output shaft end of the interception drive motor;

[0062] The blocking rod 951 is slidably installed perpendicular to the track assembly 500, and a rack 952 that meshes with the gear 953 is fixedly installed inside the blocking rod 951;

[0063] The racks 952 of the two sets of blocking rods 951 are located on both sides of the gear 953. When the gear 953 rotates, the two sets of blocking rods 951 move in opposite directions.

[0064] like Figure 3 As shown, the blocking rod 951 is driven by a gear 953 and a rack 952. The two sets of racks 952 are located on both sides of the gear 953 and mesh with the gear 953 at the same time. This allows the two sets of blocking rods 951 to move synchronously in opposite directions. That is, when one set of blocking rods 951 is in the release state, the other set of blocking rods 951 must be in the interception state. Each time, a sample component 510 or sample is accurately released, thereby ensuring the accuracy of release and precisely controlling the feed speed of the sample component 510 or sample.

[0065] In some embodiments, the interception component 950 further includes two sets of interception positioning sensors. When the blocking rod 951 moves to the interception position, the corresponding interception positioning sensor triggers feedback.

[0066] By setting up an interception positioning sensor to detect the status of the blocking rod 951, it is ensured that the blocking rod 951 is working properly, and the feedback signal of the interception positioning sensor can be used as the control input of the interception drive motor to realize the closed-loop control of the interception component 950.

[0067] In some embodiments, the sample identification component includes an RFID identification component 940 and / or a barcode identification component 930 for identifying RFID information within the sample and / or identifying barcode information of the sample.

[0068] In actual testing, samples are mostly contained in sample tubes, which are then contained in sample trays 400 or sample components 510. Since the information markings on the sample tubes are mostly barcodes, the sample identification component can use a barcode identification component 930 to identify the sample information.

[0069] Meanwhile, in practical use, the barcode recognition component 930 is limited by technology and requires the recognition component to be aligned with the barcode, making recognition difficult. Therefore, an RFID component is integrated into the sample component 510, and an RFID recognition component 940 is integrated into the sample recognition component. When in the third blocking position 900, the barcode information of the sample tube is recognized by the barcode recognition component 930, and the RFID information of the sample component 510 is recognized by the RFID recognition component 940. The upper computer binds the barcode information of the sample tube with the RFID information of the sample component 510. In subsequent inspections or in the first blocking position 700, only the RFID information in the sample component 510 is recognized, and the information of the sample component 510 and the sample tube is matched in the upper computer to determine the sample tube information in the current sample component 510, thus reducing the difficulty of sample information recognition during subsequent inspections or sample output.

[0070] In some embodiments, the sample recognition component further includes a rotating component 920, which includes a synchronous belt 921, a driven wheel 922, and a recognition drive component that drives the synchronous belt 921 to rotate, distributed on both sides of the track component 500. The synchronous belt 921 is used to contact the sample and drive the sample to rotate, and the driven wheel 922 is used to abut against the sample, thereby suppressing radial displacement of the sample.

[0071] like Figure 5 As shown, when performing barcode recognition on the sample tube, in order to ensure that the barcode recognition component 930 can rotate the barcode on the sample tube, a rotating component 920 is added to drive the sample tube to rotate. The principle is that the recognition drive component drives the synchronous belt 921 to rotate. The synchronous belt 921 contacts and rubs against the outer wall of the sample tube, causing the sample tube to rotate. During the rotation of the sample tube, the driven wheel 922 abuts against the sample tube from the other side to prevent it from undergoing radial displacement. This ensures that the sample tube will not be displaced during rotation, thereby ensuring that the barcode recognition component 930 can quickly and accurately recognize the barcode information of the sample tube.

[0072] It is worth noting that when performing barcode or RFID identification, the interception component 950 is in an interception state, fixing the sample component 510 or the sample. Therefore, the sample component 510 or the sample will not be displaced during the identification process. Thus, the driven wheel 922 only needs to ensure the rotational accuracy of the sample tube.

[0073] In some embodiments, the track assembly 500 is provided with a plurality of follow-up sample assemblies 510, the sample assemblies 510 being used to hold samples;

[0074] When the interception component 950 is in the interception state, it can force the sample component 510 to move relative to the track component 500.

[0075] The sample component 510 and the track component 500 are driven by friction. When the interception component 950 is in the interception state, the blocking rod 951 can block the feed of the sample component 510, but will not affect the overall feed of the track component 500. That is, when there is no congestion in the track component 500, the feed of each sample component 510 does not affect each other.

[0076] In some embodiments, the interception component 950 is provided with a blocking position sensor 960, which triggers feedback when the sample component 510 or the sample reaches the current blocking position.

[0077] When the sample component 510 or the sample reaches the interception position of the interception component 950, the blocking position sensor 960 is triggered. At this time, a feedback signal is sent to the host computer to control the sample recognition component to recognize the information of the sample.

[0078] In some embodiments, the sample identification component further includes a detection tube component 970, which triggers feedback when the sample component 510 containing the sample reaches the current blocking position.

[0079] like Figure 5 As shown, when the sample assembly 510 and the sample pass the first blocking position 700, the sample that meets the sampling conditions is picked up by the three-axis gripper 600. At this time, the sample assembly 510 is in an empty state, while the sample that does not meet the sampling conditions will not be picked up by the three-axis gripper 600. Therefore, the sample assembly 510 that reaches the third blocking position 900 includes both empty and full-loaded samples. Therefore, when the sample assembly 510 reaches the third blocking position 900, the sample assembly 510 can be inspected by the inspection tube assembly 970. When the sample assembly 510 is empty, the inspection tube assembly 970 is triggered and feedback is received. At this time, the three-axis gripper 600 is controlled to pick up the sample tube from the sample tray 400 for sample injection. Conversely, if the inspection tube assembly 970 is not triggered, it indicates that the sample assembly 510 is in a full-loaded state. At this time, the three-axis gripper 600 does not operate.

[0080] It is worth noting that the inspection unit 970 preferably uses an infrared sensor.

[0081] In actual use, the pusher operation module 200 is set in the form of a drawer inside the reference component 300, and the fixed part of the three-axis gripper 600 and the track component 500 are both fixedly arranged relative to the reference component 300.

[0082] Furthermore, several sets of tray fixing components 100 are fixedly installed on the pusher operation module 200. The tray fixing components 100 are used to detachably and fix the sample tray 400 to ensure that the position of the sample tray 400 is fixed during use.

[0083] Meanwhile, an electromagnet assembly is provided between the pusher operation module 200 and the reference component 300. When sample entry and exit are performed, the electromagnet assembly can be used to lock the pusher operation module 200 and the reference component 300 to prevent the pusher operation module 200 from shifting. After the sample entry and exit are completed, the electromagnet assembly is released, and the pusher operation module 200 can move relative to the reference component 300 to replace the sample tray 400.

[0084] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
