Description

Technical Field

[0001] The present invention relates to the technical field of blood collection and detection medical devices, and particularly to a sample processing device, a control method thereof, and a laboratory system. Background Art

[0002] Blood detection, as a diagnostic method, is increasingly widely used in the field of clinical medicine, and the number of blood collection tubes required is constantly increasing. The detection of vacuum blood collection tubes is generally carried out in a laboratory system, which requires steps such as centrifugation, opening the lid, inspection, covering the lid, and storage. Among them, the operations of opening and covering the lid have an important impact on the detection efficiency.

[0003] Currently, most of the lid-opening operations in the laboratory system are manually completed by medical staff. However, manual opening has the following disadvantages: laborious and time-consuming; information collection is prone to errors; there are great safety risks, such as the test tube mouth breaking and scratching medical staff, and for another example, when opening the lid, the sudden release of local negative pressure in the tube forms blood sample splashing and generates aerosols, resulting in infection of medical staff. And after opening the lid, most of the lids are directly discarded without covering, and the uncovered blood samples are extremely easy to be contaminated during storage and transportation.

[0004] To solve the above industry problems, a detection and analysis instrument has emerged on the market, which has added a lid-opening and lid-covering function module. After opening the lid, the original lid is temporarily stored by this module. After a series of detection operations are completed on the sample tube, the original lid is directly added to the sample tube by the same set of modules, that is, both the lid-opening action and the lid-covering action are completed by the same set of modules, and the two cannot be carried out simultaneously. That is to say, the lid cannot be covered during the lid-opening process, which results in a limited number of blood collection tubes processed and low efficiency, and cannot meet the current market demand for high throughput. Summary of the Invention

[0005] Based on this, in view of the above problems of low speed and low throughput, it is necessary to provide a sample processing device, a control method thereof, and a laboratory system.

[0006] A sample processing device includes a frame, a sample rack storage module, a track module, a loading module, a lid-opening module, a lid-covering module, a detection module, and a control module installed on the frame, wherein:

[0007] The sample rack storage module is used for storing a plurality of sample racks with sample tubes;

[0008] The track module includes a plurality of independent connecting tracks for transporting a plurality of sample racks with sample tubes;

[0009] The detection module is used for collecting information of the sample tube and information of the lid on the sample tube;

[0010] The loading module comprises a first loading unit and a second loading unit which are independent of each other, wherein the first loading unit has a cover opening position and is connected to the sample rack storage module for receiving and loading a first sample rack to be opened, and the second loading unit has a cover adding position and is connected to the sample rack storage module for receiving and loading a second sample rack to be added with a cover; the cover opening module is movably arranged on the first loading unit, and is used to open the cover of the first sample tube on the first sample rack located at the cover opening position when it moves to the cover opening position;

[0011] The capping module is movably disposed on the second loading unit, and is used to cap the second sample tube on the second sample rack located at the capping working position when moving to the capping working position;

[0012] The control module is signal-connected to the detection module, the cover opening module and the cover adding module respectively.

[0013] In the above-mentioned sample processing device, multiple sample racks can be placed simultaneously or one after another on multiple independent connecting tracks. The multiple connecting tracks at least transmit the first sample rack and the second sample rack to the sample rack storage module. The detection module detects the sample tubes on the sample rack. The control module controls the first sample rack to be transferred from the sample rack storage module to the first loading unit and transmitted to the uncapping work position. The first loading unit loads the first sample rack to be uncapped. The uncapping module moves to the uncapping work position and performs an uncapping operation on the first sample tube on the first sample rack. The control module controls the second sample rack to be transferred from the sample rack storage module to the second recording unit and transmitted to the capping work position. The second loading unit loads the second sample rack with a cap. The capping module moves to the capping working position and performs the capping operation on the second sample tube on the second sample rack; since the connecting tracks are independent of each other and do not interfere with each other, the receiving and loading actions of the first loading unit and the second loading unit connected to the sample rack storage module are independent of each other and do not interfere with each other, and at the same time, since the capping module and the uncapping module can move independently on the rack, the capping action and the uncapping action are also independent of each other and do not interfere with each other. Therefore, the above-mentioned sample processing device can perform the uncapping operation of the first sample tube and the capping operation of the second sample tube independently and without interfering with each other, and can perform the uncapping and capping operations on the same sample tube, can accommodate more sample tubes, and realize high-throughput and high-speed automatic capping and uncapping operations.

[0036] The mounting frame is fixed on the frame;

[0037] The second driving motor and the fourth sensor are installed on the mounting frame. The output end of the second driving motor is connected to the second synchronous wheel;

[0038] The second synchronous belt is wound around the second synchronous pulley, and positioning blocks are respectively fixed on its upper and lower sides;

[0039] The two positioning blocks are slidably installed on the mounting frame and are located on both sides of the capping working position. The opposite surfaces of the two positioning blocks form grooves that cooperate with the second sample tube.

[0040] In one embodiment, the sample processing device further includes a discard module, which is a cavity structure with an open end for receiving the lid of the first sample tube discarded by the open lid module.

[0041] In one embodiment, the open lid module includes a tube clamping unit and a lid clamping unit. The tube clamping unit is used to clamp the body of the first sample tube, and the lid clamping unit is used to clamp and rotate the lid of the first sample tube. The center lines of the tube clamping unit and the lid clamping unit are coaxially arranged.

[0042] In addition, the present invention also provides a laboratory system, including the sample processing device described in any one of the above technical solutions.

[0043] In the above laboratory system, since the sample processing device can perform the operations of opening and capping the sample tubes independently and without interference, and can perform the operations of opening and capping the same sample tube, or can perform the operations of opening and capping different sample tubes respectively, the speed of processing the sample tubes by the entire sample processing device is relatively fast, the efficiency is relatively high, and more sample tubes can be accommodated, realizing high-throughput and high-speed automatic capping and opening operations.

[0047] If the status information of the test item is a no-test-item status and there is no lid on the sample tube, then mobilize the loading module to transfer the sample tube to the capping working position and mobilize the capping module to perform capping;

[0048] If the status information of the test item is a no-test-item status and there is a lid on the sample tube, then mobilize the loading module to remove the sample tube.

[0049] In the control method of the above sample processing device, first, the detection module collects information of the sample tube. The sample tube information at least includes the status information of the sample tube corresponding to the test item to be measured, which is used to characterize whether the test item of the sample tube has been completed. Then, the detection module collects the information of the lid on the sample tube. The lid information at least includes whether there is a lid on the sample tube. Then, the control module determines the operation that the sample tube needs to perform according to the received information of the sample tube and the lid information on the sample tube. If the status information of the test item is the status of no test item and there is no lid on the sample tube at the same time, at this time the sample tube is in the open-lid state and the detection is completed, then the loading module is mobilized to transfer the sample tube to the lid-covering working position, and the lid-covering module is mobilized to cover the lid. If the status information of the test item is the status of no test item and there is a lid on the sample tube, at this time the sample tube is in the lid-covered state and the detection is completed, then the loading module is mobilized to remove the sample tube. Through the control method of the above sample processing device, the lid-covering operation of the sample tube can be carried out relatively simply and conveniently.

[0050] In one embodiment, after the step of "mobilizing the loading module to transfer the sample tube to the lid-covering working position and mobilizing the lid-covering module to cover the lid", the control method further includes: obtaining the corresponding relationship between the sample tube and the lid in the storage module. If there is a corresponding relationship, then the lid-covering module is mobilized to find the lid corresponding to the sample tube according to the above corresponding relationship and cover the lid.

[0052] In one embodiment, the control method further includes obtaining user input information. The user input information at least includes new lid requirement information. The new lid requirement information is whether the user needs to equip a new lid for the sample tube.

[0053] In one embodiment, before the step of "mobilizing the lid-covering module to find the lid corresponding to the sample tube according to the above corresponding relationship and cover the lid", if the user input information is that a new lid needs to be equipped for the sample tube, then the lid-covering module is mobilized to select a new lid from the storage module to cover the lid.

[0054] If the user input information is that a new lid does not need to be equipped for the sample tube, the lid-covering module is mobilized to find the lid corresponding to the sample tube according to the above corresponding relationship and cover the lid.

[0055] In one embodiment, if the status information of the test item is the registration status and there is no lid on the sample tube, then the loading module is mobilized to remove the sample tube.

[0056] If the status information of the item to be measured is the registration status and there is a lid on the sample tube, the loading module is mobilized to transfer the sample tube to the open-lid working position, and the open-lid module is mobilized to open the lid.

[0057] In one embodiment, the control method further includes obtaining user input information, the user input information at least includes the original lid requirement, and the original lid requirement is whether the user needs to retain the original lid. If the user input information is that the original lid does not need to be retained, after "mobilizing the loading module to transfer the sample tube to the open-lid working position and mobilizing the open-lid module to open the lid", the open-lid module or the lid-covering module is mobilized to move to the discard module to discard the original lid;

[0058] If the user input information is that the original lid needs to be retained, after "mobilizing the loading module to transfer the sample tube to the open-lid working position and mobilizing the open-lid module to open the lid", the lid-covering module is mobilized to move to the storage module to store the original lid.

[0092] The technical solutions provided by the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0093] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a sample processing device 10 for realizing the simultaneous opening and capping operations of vacuum blood collection tube samples. The sample processing device 10 includes a frame 100, a track module 200, a sample rack storage module 101, a loading module 300, an uncapping module 400 and a capping module 500. The track module 200, the sample rack storage module 101, the loading module 300, the uncapping module 400 and the capping module 500 are installed on the frame 100, and the uncapping module 400 and the capping module 500 can move relative to the frame 100. It should be noted that a sample rack transportation module 102, a detection module 103 and a control module are also provided on the frame 100 of the above sample processing device 10 for realizing the automatic opening and capping operations of vacuum blood collection tube samples. Among them:

[0094] The track module 200 includes a plurality of connecting tracks 210. These connecting tracks 210 are independent of each other and do not interfere with each other, and these connecting tracks 210 are used to receive and transport a plurality of sample racks, and there are a plurality of sample tubes on the sample racks; when specifically arranged, the plurality of connecting tracks 210 are parallel to each other and arranged at a certain distance. The plurality of connecting tracks 210 can be arranged on the same side of the frame 100 to facilitate the arrangement of each module in the sample processing device 10. Of course, the arrangement method of the plurality of connecting tracks 210 is not limited to this, and other arrangement methods can also be used. For example, the plurality of connecting tracks 210 can be arranged on opposite sides of the frame 100.

[0095] The loading module 300 includes a first loading unit 310 and a second loading unit 320. The first loading unit 310 and the second loading unit 320 are independent of each other and do not interfere with each other. The directions of the first loading unit 310 and the second loading unit 320 for loading the sample racks are the same so that the sample injection directions are the same. In this way, it can cooperate with the existing sample warehouse and connecting tracks, or the longer connecting tracks can be disassembled into smaller connecting tracks, and the placement positions of the connecting tracks can be flexibly changed, so that the volume of the entire device or system is reduced and the occupied space is also reduced. The loading module 300 is used to receive the sample rack and transport it to a designated position and stop waiting for subsequent operations. When specifically arranged, the track module 200, the first loading unit 310, and the second loading unit 320 can be arranged in sequence on the frame 100. And to save space, the track module 200, the first loading unit 310, and the second loading unit 320 can be parallel to each other and arranged at a certain distance. Of course, the arrangement methods of the track module 200, the first loading unit 310, and the second loading unit 320 are not limited to this, and other methods that can meet the requirements can also be used. For example, the first loading unit 310 and the second loading unit 320 are arranged on both sides of the track module 200.

[0096] The sample rack storage module 101 is installed on the frame 100 and has a plurality of parallel positions. A plurality of first sample racks and a plurality of second sample racks 20 can be correspondingly stored in the plurality of positions. The plurality of first sample racks and the plurality of second sample racks 20 can be placed in the sample rack storage module 101 before starting work. The sample rack storage module 101 can also store the plurality of first sample racks and the plurality of second sample racks 20 transported from the track module. The first loading unit 310 is docked with the sample rack storage module 101. The first loading unit 310 has an open cover working position. The first loading unit 310 is used to receive and load the first sample rack to be opened. When specifically arranged, the first loading unit 310 receives the first sample rack to be opened output from the sample rack storage module 101, and the first loading unit 310 loads the first sample rack when the first sample rack is transported to the open cover working position.

[0097] The second loading unit 320 is docked with the sample rack storage module 101. The second loading unit 320 has a capping working position, and the second loading unit is used to receive and load the second sample rack 20 to be capped. Specifically, the second loading unit receives the second sample rack 20 to be capped output from the sample rack storage module 101, and loads the second sample rack 20 when the second sample rack 20 is transported to the capping working position.

[0098] Position sensors are provided on both the first loading unit 310 and the second loading unit 320, which can detect whether the sample rack is loaded to the uncapping or capping working position. The first loading unit 310 and the second loading unit 320 can be transported independently of each other without interference, which can improve the efficiency of uncapping or capping of the entire sample processing device.

[0099] The loading of the first sample rack and the second sample rack 20 realizes the automatic loading of the first sample rack and the second sample rack 20 through the sample rack transportation module 102. The sample rack transportation module 102 is used to realize the transfer of the first sample rack between the sample rack storage module 101 and the first loading unit 310. The sample rack transportation module 102 is also used to realize the transfer of the second sample rack 20 between the sample rack storage module 101, the second loading unit and the connecting track 210.

[0100] The uncapping module 400 is arranged above the first loading unit 310, and the uncapping module 400 is movable relative to the first loading unit 310. The uncapping module 400 is used to uncapp the first sample tube on the first sample rack located at the uncapping working position when the first sample rack moves to the uncapping working position. Specifically, the uncapping module 400 includes a tube clamping unit and a cap clamping unit. The tube clamping unit is used to clamp the body of the first sample tube, and the cap clamping unit is used to clamp and rotate the cap of the first sample tube. The center lines of the tube clamping unit and the cap clamping unit are coaxial. The tube clamping unit is used to clamp the body of the first sample tube, and the cap clamping unit is used to clamp the cap of the first sample tube. When the uncapping module 400 moves to the uncapping working position, the center lines of the tube clamping unit, the cap clamping unit and the first sample tube are coaxial to ensure the accuracy of the uncapping operation and avoid damaging the first sample tube.

[0101] The capping module 500 is arranged above the second loading unit 320, and the capping module 500 is movable relative to the second loading unit 320. The capping module 500 is used to cap the second sample tube 30 on the second sample rack 20 located at the capping working position when moving to the capping working position. To ensure the accuracy of capping, the stroke of the capping module 500 covers all the second sample tubes 30 on the second sample rack 20 to avoid the situation where the second sample tube 30 cannot be capped.

[0102] The detection module 103 is used to collect information about the sample tube and the information about the cover on the sample tube; in the specific setting, the detection module 103 can be set on the sample rack transport module 102, and the detection module 103 can also be set on the connecting track 210. Of course, the setting position of the detection module 103 is not limited to this, and can also be other ways that can meet the requirements; the detection module 103 may include a camera unit, and the detection module 103 may also include a code scanning unit. The detection module 103 is used to identify the type, height, cover, barcode and other information of the first sample tube and the second sample tube 30.

[0103] The control module is connected to the detection module 103, the cover opening module 400 and the cover adding module 500 by signal. The control module receives information such as the type, height, cover, barcode, etc. of the first sample tube and the second sample tube 30 from the detection module 103, and compares the information with the pre-stored information to determine the operation to be performed on the first sample tube and the second sample tube 30. The control module controls the cover opening module 400 to open the cover of the first sample tube and to add the cover to the second sample tube 30 according to the information judgment result. In the specific setting, the control module can be a PLC (programmable logic controller) or other structural forms that can meet the requirements.

[0104] In the above-mentioned sample processing device 10, multiple sample racks can be placed simultaneously or one after another on multiple independent connecting tracks 210. The multiple connecting tracks 210 at least transmit the first sample rack and the second sample rack 20 to the sample rack storage module 101. The detection module 103 detects the sample tubes on the sample rack. The control module controls the first sample rack to be transferred from the sample rack storage module 101 to the first loading unit 310 and transmitted to the uncapping work position. The first loading unit 310 loads the first sample tube to be uncapped. The uncapping module 400 moves to the uncapping work position and performs an uncapping operation on the first sample tube on the first sample rack. The control module controls the second sample rack 20 to be transferred from the sample rack storage module 101 to the second loading unit 320 and transmitted to the capping work position. The second loading unit 320 loads the second sample rack to be capped. 20, the capping module 500 moves to the capping working position and performs the capping operation on the second sample tube 30 on the second sample rack 20; since the connecting rails 210 are independent of each other and do not interfere with each other, the receiving and loading actions of the first loading unit 310 and the second loading unit 320 connected to the sample rack storage module 101 are independent of each other and do not interfere with each other, and at the same time, since the capping module 500 and the uncapping module 400 can move independently on the rack 100, the capping action and the uncapping action are also independent of each other and do not interfere with each other. Therefore, the above-mentioned sample processing device 10 can perform the uncapping operation of the first sample tube and the capping operation of the second sample tube 30 independently and without interfering with each other, and can perform the uncapping and capping operations on the same sample tube, can accommodate more sample tubes, and realize high-throughput and high-speed automatic capping and uncapping operations.

[0105] To facilitate the loading of a suitable lid, such as Figure 3 shown, in a preferred embodiment, the sample processing device 10 further includes a transfer module 600 and a storage module 700. The storage module 700 is disposed on a side of the lid opening module 400 facing away from the track module 200. The transfer module 600 and the storage module 700 are mounted on the frame 100, and the transfer module 600 is movable relative to the frame 100. Among them:

[0106] The transfer module 600 is disposed below the lid opening module 400, and the transfer module 600 is movable relative to the lid opening module 400. Specifically, when the transfer module 600 moves to directly below the lid opening module 400, it receives the lid from the lid opening module 400. When the transfer module 600 carries the lid and moves to directly below the lid covering module 500, the lid covering module 500 transfers the lid to the storage module 700. Specifically, the transfer module 600 includes a horizontal driving unit, a vertical driving unit, and a storage box. The horizontal driving unit and the vertical driving unit are respectively mounted on the frame. The storage box is mounted on the horizontal driving unit and is in transmission connection with the vertical driving unit. The horizontal driving unit operates to drive the storage box to move horizontally therewith, and the vertical driving unit operates to drive the storage box to move vertically therewith to approach the lid opening module 400 for receiving the lid.

[0107] The control module is signal-connected to the transfer module 600 for controlling the movement of the transfer module 600. When the sample tube needs to be covered with the original lid, the control module controls the transfer module 600 to receive the lid from the lid opening module 400 and continues to control the transfer module 600 to transfer the lid to the storage module 700, and controls the lid covering module 500 to grab the original lid on the storage module 700 during lid covering.

[0108] In the above sample processing device 10, the sample rack transportation module 102 takes out the first sample rack from the sample rack storage module 101. The detection module 103 performs detection operations such as photographing and bar code scanning on the first sample tube to obtain information such as the type, height, lid, and bar code of the first sample tube, and transmits this information to the control module. Then, the sample rack transportation module 102 transfers the first sample rack from the sample rack storage module 101 to the first loading unit 310 and transports it to the open-lid working position. The first loading unit 310 loads the first sample rack to be opened. The open-lid module 400 moves to the open-lid working position and performs an open-lid operation on the first sample tube on the first sample rack. The control module determines whether the first sample tube needs to be capped based on the received information of the first sample tube. When it is determined that the first sample tube does not need to be capped or needs a new cap, the control module sends a first control signal to the open-lid module 400. The open-lid module 400 directly discards the lid into the discard module 104 according to the first control signal. When the control module determines that the first sample tube needs to be capped with the original cap, it sends a second control signal to the transfer module 600. The transfer module 600 receives the lid from the open-lid module 400 according to the second control signal and transfers the lid to a set position on the storage module 700 for subsequent capping of the first sample tube. Then, the opened first sample tube is transferred from the first loading unit 310 to the sample rack storage module 101 through the sample rack transportation module 102 for subsequent sample detection, and is returned to the sample rack storage module 101 after the sample detection is completed.

[0109] The sample rack transportation module 102 takes out the second sample rack 20 from the sample rack storage module 101. The detection module 103 performs detection operations such as photographing and bar code scanning on the second sample tube 30 to obtain information such as the type, height, lid, and bar code of the second sample tube 30, and transmits this information to the control module. Then, the sample rack transportation module 102 transfers the second sample rack 20 from the connection track 210 to the second loading unit 320 and transports it to the capping working position. The second loading unit 320 loads the second sample rack 20 to be capped. The capping module 500 moves to the capping working position and performs a capping operation on the second sample tube 30 on the second sample rack 20. The control module determines whether the second sample tube 30 is the first sample tube after the lid is opened based on the received information of the second sample tube 30. When it is determined that the second sample tube 30 is not the first sample tube after the lid is opened or the second sample tube 30 does not require the original lid to be added, the control module sends a third control signal to the capping module 500. The capping module 500 grabs a new lid from the storage module 700 according to the third control signal and performs a new lid capping operation on the second sample tube 30 on the second sample rack 20. When the control module determines that the second sample tube 30 is the first sample tube after the lid is opened and the second sample tube 30 does not require the original lid to be added, it sends a fourth control signal to the capping module 500. The capping module 500 grabs the original lid from the storage module 700 according to the fourth control signal and performs an original lid capping operation on the second sample tube 30 on the second sample rack 20, that is, the lid removed before was removed from this sample tube, and this lid is still used for capping during capping, so that neither consumables are increased nor cross-contamination is generated. Finally, the second sample tube 30 after the capping operation is transferred from the second loading unit to the sample rack storage module 101 through the sample rack transportation module 102 for subsequent operations.

[0110] Through the lid opening and capping processes of the above sample processing device 10, the problematic (such as pinched or damaged) lids removed can be discarded, or all the removed lids can be discarded and then new lids placed in advance can be added. When there is a problem with the original lid on the first sample tube, it can be discarded after the lid is opened, and a new lid can be replaced in time when capping is required. At the same time, a new lid or the original lid can be added to the second sample tube 30.

[0111] It should be noted that, such as Figure 1 and Figure 4As shown in the figure, the storage module 700 is disposed close to the lid opening module 400, and at least one discard module 104 is provided on one side of the storage module 700 close to the lid opening module 400. The discard module 104 is a cavity structure with an open end. For example, the discard module 104 is a cylinder with an open end, and the discard module 104 is used to receive the lids of the sample tubes discarded by the lid opening module 400. When there is one discard module 104, the discard module 104 can be disposed directly below the lid opening module 400. When there are multiple discard modules 104, one discard module 104 is disposed directly below the lid opening module 400, and the remaining discard modules 104 are disposed adjacent to the storage module 700, and these discard modules 104 can be connected to a trash bin.

[0112] It is also worth noting that, as Figure 1 , Figure 2 and Figure 3 shown, the above-mentioned sample processing device 10 further includes an ultraviolet disinfection module 105. The ultraviolet disinfection module 105 is disposed on the frame 100 and above the storage module 700. The range that can be disinfected by the ultraviolet disinfection module 105 at least includes the storage module 700.

[0113] The structure of the storage module 700 has various forms. The storage module 700 can be detachably connected to the frame or some of its structures can be detachably connected. As Figure 5 and Figure 6 shown, in a preferred embodiment, the storage module 700 includes two parts, a second support plate 710 and a tray 720. The second support plate 710 is fixed to the frame 100 by means of screw thread connection, snap fit, concave-convex fit, etc. A plurality of storage positions 721 are provided on the tray 720, and the storage positions 721 are used to store lids. The storage positions 721 can be slot holes, and the top of the slot holes has a chamfer. The size and depth of the slot holes are determined according to the size of the lids. The tray 720 is mounted on the second support plate 710, and the tray 720 is detachable relative to the second support plate 710. It can be taken out regularly to add new lids, clean, and disinfect to avoid cross-contamination. At the same time, when the lid opening module works alone and the lid adding module does not work, the storage module can be taken out to add new lids or clean. In specific settings, the detachable connection between the tray 720 and the second support plate 710 can be realized by the structure of a guide groove 722 and a guide block, and can also be realized by the structure of a guide rail and a slider. Of course, the detachable connection method between the tray 720 and the second support plate 710 is not limited to this, and can also be other forms that can meet the requirements.

[0114] In the above sample processing device 10, when the original lid is directly discarded and a new lid is needed, multiple new lids can be pre-stored on the tray 720, and then the tray 720 loaded with the new lids is installed on the second support plate 710 to form a storage module 700. When the original lid and the new lid are used simultaneously, multiple new lids can be pre-stored on the tray 720, and then the tray 720 loaded with the new lids is installed on the second support plate 710, and the original lid taken from the first sample can also be stored on the tray 720. Therefore, by defining the structure of the storage module 700 as the second support plate 710 and the tray 720, it is possible to more conveniently achieve the storage of lids and the replacement of new lids, and the cooperation of the guide groove and the guide block makes the structure simple and the installation convenient.

[0115] To facilitate the positioning of the tray 720, specifically, as Figure 5 and Figure 6 shown, the storage module 700 further includes a limiting unit 730. The limiting unit 730 includes a plurality of limiting posts 731. The plurality of limiting posts 731 are respectively arranged on the peripheral side of the second support plate 710. The limiting posts 731 are used to limit the second support plate 710, and the limiting posts 731 cooperate with the guide groove 722 on one side of the tray 720. When specifically arranged, the plurality of limiting posts 731 are embedded in the second support plate 710, and the plurality of limiting posts 731 can be integrally formed with the second support plate 710. The number of the limiting posts 731 can be two, three, four or more than four. More specifically, the limiting unit 730 further includes a guide block 732. The guide block 732 is located at one end of the second support plate 710. The front side of the tray 720 is provided with a guide groove 722 in the shape of a flared opening, which matches the limiting posts 731.

[0116] In the above sample processing device 10, the tray 720 is pushed from one end of the second support plate 710 onto the second support plate 710 until the guide groove 722 on one side of the tray 720 abuts against the limiting posts 731 on the same side to complete the installation of the tray 720. Since the limiting posts 731 are arranged on the peripheral side of the second support plate 710, the limiting posts 731 limit the moving distance of the tray 720 on the second support plate 710 to prevent the tray 720 from shaking on the second support plate 710. Therefore, by providing the limiting posts 731 and the guide block 732 in the storage module 700, it is possible to more conveniently limit the tray 720 and ensure the accurate position of the tray 720, so that the actions of storing and taking out the lids can be carried out accurately.

[0117] To facilitate the installation of the tray 720, as Figure 6As shown, more specifically, the guiding block 732 is a wedge-shaped block protruding from the surface of the second support plate 710. The guiding block 732 has a guiding inclined surface 7321. In the direction perpendicular to the surface of the second support plate 710, from the edge of the second support plate 710 towards the center of the second support plate 710, the height of the guiding inclined surface 7321 gradually decreases.

[0118] In the above sample processing device 10, the tray 720 is pushed onto the second support plate 710 from one end of the second support plate 710. The tray 720 moves along the guiding inclined surface 7321. After the bottom surface of the tray 720 is placed on the second support plate 710 and pushed forward for a certain distance, due to the action of gravity, the tray 720 will slide down along the guiding inclined surface 7321 until the bottom surface of the tray 720 is completely attached to and limited by the top surface of the second support plate 710 to complete the installation of the tray 720. The limiting post 731 and the guiding block 732 limit the moving distance of the tray 720 on the second support plate 710 to prevent the tray 720 from shaking on the second support plate 710. Therefore, by providing the guiding inclined surface 7321 on the guiding block 732, the tray 720 can be installed and limited more conveniently, ensuring the accurate position of the tray 720, so that the actions of storing and taking out the lid can be carried out accurately. The capping module 500 can cover the entire area of the storage module 700, can store new lids, so there is no need to separately set up a new lid loading mechanism, reducing the volume and occupied space of the instrument. When the original lid is damaged, a new lid can be directly added, improving the sample utilization rate. At the same time, the original lid can also be stored, covering the original lid of the sample tube back, reducing the consumable cost. Users have multiple choices and a good experience.

[0119] The structure of the capping module 500 has various forms, such as Figure 5 and Figure 7 As shown, in a preferred embodiment, the capping module 500 includes a support frame 510, three driving mechanisms 520 fixed on the support frame 510, and a capping mechanism 530 installed on one of the driving mechanisms 520, where:

[0120] The support frame 510 is fixed on the frame 100 by means of screw thread connection, snap fit, concave-convex fit, etc. The first driving mechanism 521 among the three driving mechanisms 520 is installed on the support frame 510, and the first driving mechanism 521 has a first output end that moves along the first direction;

[0121] The second driving mechanism 522 among the three driving mechanisms 520 is installed on the first output end, and the second driving mechanism 522 has a second output end that moves along the second direction;

[0122] The third driving mechanism 523 of the three driving mechanisms 520 is installed on the second output end, and the third driving mechanism 523 has a third output end moving along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other; in a specific setting, the first direction can be the X direction, the second direction can be the Y direction, and the third direction can be the Z direction.

[0123] The capping mechanism 530 is installed on the third output terminal, and the capping mechanism 530 has a clamping claw 531 for clamping the cap.

[0124] In the above-mentioned sample processing device 10, the first driving mechanism 521 is operated, the first output end moves along the first direction, and drives the second driving mechanism 522 installed thereon to move along the first direction. The second driving mechanism 522 is operated, the second output end moves along the second direction, and drives the third driving mechanism 523 installed thereon to move along the second direction. The third driving mechanism 523 is operated, the third output end moves along the third direction, and drives the capping mechanism 530 installed thereon to move along the third direction, so as to realize the movement of the capping mechanism 530 in the first direction, the second direction and the third direction. The capping mechanism 530 clamps the cover by controlling the clamping claw 531. Therefore, by defining the structure of the capping module 500 as the support frame 510, the driving mechanism 520 and the capping mechanism 530, the movement of the capping mechanism 530 in the first direction, the second direction and the third direction can be realized more conveniently, and the structure is simple and easy to install and control. In the specific setting, the structures of the first drive mechanism 521, the second drive mechanism 522 and the third drive mechanism 523 can be the same, for example, they are all in the form of a motor, a synchronous belt and a synchronous wheel. The structures of the first drive mechanism 521, the second drive mechanism 522 and the third drive mechanism 523 can also be different, for example, the first drive mechanism 521 is in the form of a motor, a synchronous belt and a synchronous wheel, and the second drive mechanism 522 and the third drive mechanism 523 are in the form of a motor and a gear transmission assembly.

[0125] The structure of the driving mechanism 520 has various forms, such as Figure 7 As shown, in a preferred embodiment, the driving mechanism 520 includes a mounting plate, a first driving motor, two conveying wheels, a conveying belt and a third sensor, wherein;

[0126] Two transmission wheels are mounted on the mounting plate, and the two transmission wheels are rotatable relative to the mounting plate;

[0127] The first drive motor and the third sensor are fixed on the mounting plate by screw thread connection, snap fit, concave-convex fit, etc., the output shaft of the first drive motor is drivingly connected to a transmission wheel, and the first drive motor is signal-connected to the third sensor;

[0128] The conveyor belt is sleeved on two conveyor wheels;

[0129] The mounting plate 524A of the first driving mechanism 521 is fixed on the support frame 510 by means of screw thread connection, snap fit, concave-convex fit, etc. And the conveyor belt 527A of the first driving mechanism 521 forms a first output end. The third sensor 528A of the first driving mechanism 521 is arranged close to one of its conveyor wheels 526A for detecting whether the first driving mechanism 521 is initialized.

[0130] The mounting plate 524B of the second driving mechanism 522 is fixed on the conveyor belt 527B of the first driving mechanism 521 by means of screw thread connection, snap fit, concave-convex fit, etc. And the conveyor belt 527B of the second driving mechanism 522 forms a second output end. The third sensor 528B of the second driving mechanism 522 is arranged close to one of its conveyor wheels 526B for detecting whether the second driving mechanism 522 is initialized.

[0131] The mounting plate 524C of the third driving mechanism 523 is fixed on the conveyor belt 527C of the second driving mechanism 522 by means of screw thread connection, snap fit, concave-convex fit, etc. And the conveyor belt 527C of the second driving mechanism 522 forms a third output end. The third sensor 528C of the third driving mechanism 523 is arranged close to one of its conveyor wheels 526C for detecting whether the third driving mechanism 523 is initialized. Or, the third sensor 528C of the third driving mechanism 523 is arranged close to the gripper 531 for detecting which storage positions 721 on the scanning tray 720 have lids when picking up or discarding.

[0132] The lid covering mechanism 530 is fixed on the conveyor belt 527C of the third driving mechanism 523; When specifically set, the lid covering mechanism 530 is fixed on the conveyor belt 527C of the third driving mechanism 523 through an adapter plate.

[0133] In the above sample processing device 10, the number of transfer modules 600 can be one. At this time, this one transfer module 600 is only used to receive the lids taken off by the lid opening module 400. The taken-off lids will be placed on the storage module 700 by the gripper of the lid covering module 500. The lid covering module 500 picks up the lids from the storage module 700 and performs the lid covering operation. At this time, the stroke of the lid covering module 500 covers the storage module 700.

[0134] The specific working process of the capping module 500 is as follows: The first driving motor 525A of the first driving mechanism 521 operates, driving the conveyor wheel 526A of the first driving mechanism 521 to move, and then driving the conveyor belt 527A of the first driving mechanism 521 to move along the first direction, driving the second driving mechanism 522 mounted thereon to move along the first direction. When the third sensor 528A of the first driving mechanism 521 detects the initialization of the first driving mechanism 521, it sends an action signal to the first driving motor 525A of the first driving mechanism 521, and the first driving motor 525A of the first driving mechanism 521 ends its operation; The first driving motor 525B of the second driving mechanism 522 operates, driving the conveyor wheel 526B of the second driving mechanism 522 to move, and then driving the conveyor belt 527B of the second driving mechanism 522 to move along the second direction, driving the third driving mechanism 523 mounted thereon to move along the second direction. When the third sensor 528B of the second driving mechanism 522 detects the initialization of the second driving mechanism 522, it sends an action signal to the first driving motor 525B of the second driving mechanism 522, and the first driving motor 525B of the second driving mechanism 522 ends its operation; The first driving motor 525C of the third driving mechanism 523 operates, driving the conveyor wheel 526C of the third driving mechanism 523 to move, and then driving the conveyor belt 527C of the third driving mechanism 523 to move along the third direction, driving the capping mechanism 530 mounted thereon to move along the third direction. When the third sensor 528C of the third driving mechanism 523 detects the initialization of the third driving mechanism 523, it sends an action signal to the first driving motor 525C of the third driving mechanism 523, and the first driving motor 525C of the third driving mechanism 523 ends its operation; To realize the movement of the capping mechanism 530 in the first direction, the second direction, and the third direction, the capping mechanism 530 controls the clamping jaws 531 to realize the clamping of the lid. Therefore, by defining the structure of the driving mechanism 520 as a mounting plate, a first driving motor, two conveyor wheels, a conveyor belt, and a third sensor, it is possible to more conveniently realize the movement of the capping mechanism 530 in the first direction, the second direction, and the third direction, with a simple structure and easy installation and control.

[0135] To facilitate the positioning of the second sample tube 30, as Figure 8 well as Figure 9 shown, in a preferred embodiment, the sample processing device 10 further includes a positioning module 800. The positioning module 800 includes a mounting frame 810, a second driving motor 820, two positioning blocks 830, a second synchronous belt 840, a second synchronous pulley 850, and a fourth sensor 860, where:

[0136] The mounting frame 810 is fixed to the frame 100 by means of screw thread connection, snap fit, concave-convex fit, welding, etc.

[0137] The second drive motor 820 and the fourth sensor 860 are mounted on the mounting bracket 810 by means of screw threading, snap fitting, concave-convex fitting, etc. The output end of the second drive motor 820 is connected to the second synchronous pulley 850, and the second drive motor 820 is signal-connected to the fourth sensor 860. When specifically arranged, the two second synchronous pulleys 850 are arranged on one side of the mounting plate 524C, and the two second synchronous pulleys 850 are respectively arranged at both ends of the mounting plate 524C. The second drive motor 820 is arranged on the other side of the mounting plate 524C. The second drive motor 820 and one second synchronous pulley 850 are arranged opposite to each other, and the fourth sensor 860 is arranged close to this second synchronous pulley 850. The output end of the second drive motor 820 penetrates through the mounting plate 524C and is in transmission connection with the second synchronous pulley 850.

[0138] The second synchronous belt 840 is wound around the second synchronous pulley 850, and positioning blocks 830 are respectively fixed on the upper and lower sides of the second synchronous belt 840. When specifically arranged, a retaining piece 870 is fixedly arranged on the positioning block 830 close to the second drive motor 820. The retaining piece 870 and the positioning block 830 can be independently arranged, and the retaining piece 870 and the positioning block 830 can also be of an integral structure. The retaining piece 870 is used for the detection and positioning of the fourth sensor 860, and the fourth sensor 860 judges whether the positioning module 800 is in the initialization state according to the position of the retaining piece 870.

[0139] The two positioning blocks 830 are slidably mounted on the mounting bracket 810, and the two positioning blocks 830 are located on both sides of the capping working position. The opposite surfaces of the two positioning blocks 830 form grooves 831 that cooperate with the second sample tube 30. When specifically arranged, a positioning linear guide 880 is arranged on the mounting bracket 810, and a positioning slider 890 is arranged on each positioning block 830. The two positioning sliders 890 are mounted on the positioning linear guide 880, and the positioning slider 890 is slidable relative to the positioning linear guide 880. The grooves 831 on the opposite surfaces of the two positioning blocks 830 can be in the shapes of a wave, an arc, etc., so as to match the radian of the second sample tube 30. The centers of the two grooves 831 and the center connection line of the second sample tube 30 are on a straight line, so as to facilitate the positioning of the second sample tube 30.

[0140] In the above sample processing device 10, the second drive motor 820 operates, and its output end moves to drive the second synchronous pulley 850 to rotate, so that the second synchronous belt 840 moves. The second synchronous belt 840 drives two positioning blocks 830 fixed on its upper and lower sides to slide relative to the mounting frame 810. Moreover, the forward and reverse movements of the second drive motor 820 can realize the approaching and separating movements of the two positioning blocks 830, and further can realize the clamping and separation of the second sample tube 30 by the two positioning blocks 830. When the two positioning blocks 830 move in the opposite direction and the fourth sensor 860 detects that the baffle 870 returns to the initial position, an action signal is sent to the second drive motor 820, and the second drive motor 820 ends its operation. The two positioning blocks 830 return to the initial position, and the positioning module 800 is in the initialization state. This ensures the stability and non-shaking of the sample tube during the capping process, ensures the same height of the sample tubes, accurate positioning, and improves the capping efficiency. When specifically set, the structural member for realizing the movement of the positioning block 830 is not limited to the above second drive motor 820, and can also be other structural forms that can meet the requirements.

[0141] In addition, the present invention also provides a laboratory system, including the sample processing device 10 according to any one of the above technical solutions.

[0142] In the above laboratory system, since the sample processing device 10 can perform the uncapping operation of the first sample tube and the capping operation of the second sample tube 30 independently and without interference, and can also perform the uncapping and capping operations on the same sample tube, or perform the uncapping and capping operations on different sample tubes respectively, the entire sample processing device 10 can process sample tubes at a relatively fast speed and high efficiency, and can also accommodate more sample tubes, realizing high-throughput and high-speed automatic capping and uncapping operations.

[0143] As Figure 10 shown, in addition, the present invention also provides a control method for the sample processing device 10 according to any one of the above technical solutions. The control method of the sample processing device includes:

[0144] Step S101, obtaining sample tube information, where the sample tube information at least includes the status information of the sample tube corresponding to the test item; when specifically set, the detection module 103 scans the sample tube to collect the sample tube information on the sample rack. At this time, the sample rack includes the first sample rack and the second sample rack 20, and the information collected by the detection module 103 includes the information of the first sample tube and the second sample tube 30. This information includes the status information of the sample tube corresponding to the test item, and this information can also include the model information of the sample tube, etc.

[0145] Step S102: Obtain the lid information on the sample tube. The lid information includes at least whether there is a lid on the sample tube. Specifically, the detection module 103 takes a photo of the sample tube to collect the lid information of the sample tube, including whether there is a lid on the sample tube or not.

[0146] Step S103: The control module receives the sample tube information and the lid information on the sample tube from the detection module 103, and analyzes and judges this information through a logic program. If the status information of the item to be tested is in a state of no item to be tested and there is no lid on the sample tube, the control module determines that a lid needs to be added, then activates the loading module to transfer the sample tube to the lid-adding working position, and activates the lid-adding module to add a lid. Specifically, when the control module determines that the sample tube needs to be lidded, it transfers the sample tube to the lid-adding working position through the sample rack transportation module 102 and waits for the lid-adding module 500 to perform the lid-adding operation.

[0147] Step S104: The control module receives the sample tube information and the lid information on the sample tube from the detection module 103, and analyzes and judges this information through a logic program. If the status information of the item to be tested is in a state of no item to be tested and there is a lid on the sample tube, the control module determines that no lid needs to be added, then activates the loading module to remove the sample tube.

[0148] In the control method of the above sample processing device 10, first, the detection module 103 collects the information of the sample tube, and the sample tube information includes at least the status information of the item to be tested corresponding to the sample tube, which is used to represent whether the sample tube has completed the item to be tested. Then, the detection module 103 collects the lid information on the sample tube, and the lid information includes at least whether there is a lid on the sample tube. Then, the control module judges the operation that the sample tube needs to perform according to the received sample tube information and the lid information on the sample tube. If the status information of the item to be tested is in a state of no item to be tested and at the same time there is no lid on the sample tube, at this time the sample tube is in an open-lid state and the detection is completed, then activate the loading module 300 to transfer the sample tube to the lid-adding working position, and activate the lid-adding module 500 to add a lid. If the status information of the item to be tested is in a state of no item to be tested and there is a lid on the sample tube, at this time the sample tube is in a lidded state and the detection is completed, then activate the loading module 300 to remove the sample tube. Through the above control method of the sample processing device 10, the lid-adding operation of the sample tube can be carried out relatively simply and conveniently.

[0149] To load a suitable lid conveniently and quickly, in a preferred embodiment, after "activating the loading module 300 to transfer the sample tube to the lid - adding working position and activating the lid - adding module 500 to add a lid" in step S103, the control method further includes: obtaining the correspondence between the sample tube and the lids in the storage module 700. If there is a correspondence, then activate the lid - adding module 500 to find the lid corresponding to the sample tube according to the above - mentioned correspondence and add the lid, so as to obtain the original lid and add it when the original lid needs to be added;

[0150] If there is no correspondence, then activate the lid - adding module 500 to select a new lid from the storage module 700 to add a lid, so as to obtain a new lid and add it when the original lid does not need to be added.

[0151] In the control method of the above - mentioned sample processing device 10, when the control module determines that the original lid is in good condition according to the information collected by the detection module 103, after opening the lid, the original lid is placed on the storage module 700 waiting to be reused. When the control module obtains that there is a correspondence between the sample tube and the lids in the storage module 700 and determines that the original lid needs to be added, it obtains the original lid and adds it to reuse the original lid and save costs; when the control module determines that the original lid is difficult to be reused again according to the information collected by the detection module 103, for example, when there are problems with the original lid (such as breakage, deformation, stains, etc.), the original lid after opening is directly discarded. When the control module obtains that there is no correspondence between the sample tube and the lids in the storage module 700 and determines that the original lid does not need to be added, the lid - adding module 500 obtains a new lid and adds it. By replacing the lid with a new one, it can avoid contaminating the sample.

[0152] To obtain the correspondence between the sample tube and the lids in the storage module 700 conveniently and quickly, specifically, the control method further includes obtaining user - input information. The user - input information at least includes new - lid requirement information, and the new - lid requirement information is whether the user needs to equip a new lid for the sample tube.

[0153] In the control method of the above - mentioned sample processing device 10, the detection module 103 collects information to determine the usage condition of the original lid. When the original lid is in good condition, the lid can be reused, and the user - input information is that there is no need to equip a new lid for the sample tube. When the original lid is in poor condition, a new lid needs to be updated, and the user - input information is that there is a need to equip a new lid for the sample tube. The control module obtains the user - input information and determines whether the user needs to equip a new lid for the sample tube according to the user - input information, thereby being able to conveniently and quickly obtain the correspondence between the sample tube and the lids in the storage module 700.

[0154] To load a suitable lid more conveniently and quickly, more specifically, before "activating the lid - adding module to find the lid corresponding to the sample tube according to the above - mentioned correspondence and add the lid", if the user - input information is that there is a need to equip a new lid for the sample tube, then activate the lid - adding module 500 to select a new lid from the storage module 700 to add a lid;

[0155] If the user input information is that a new lid does not need to be equipped for the sample tube, the capping module 500 is mobilized to find the corresponding lid for the sample tube according to the above corresponding relationship and cap it.

[0156] In the control method of the above sample processing device 10, the control module obtains the user input information. If the user input information is that a new lid needs to be equipped for the sample tube, at this time, the sample tube corresponds to a new lid, the control module determines that the sample tube needs a new lid, and the control module mobilizes the capping module 500 to select a new lid from the storage module 700 for capping; the control module obtains the user input information. If the user input information is that a new lid does not need to be equipped for the sample tube, at this time, the sample tube corresponds to the original lid, the control module determines that the sample tube needs the original lid, and the control module mobilizes the capping module 500 to find the corresponding original lid of the sample tube from the storage module 700 according to the above corresponding relationship and cap it.

[0157] In order to speed up the speed of the sample processing device 10 for processing the sample tube, in a preferred implementation, if the control module receives that the status information of the item to be tested is the registration status, and the control module receives that there is no lid on the sample tube, the control module determines that the sample tube has been opened, but the sample has not been tested yet. At this time, it is determined that the sample has been contaminated, and the control module mobilizes the loading module 300 to remove the sample tube;

[0158] If the control module receives that the status information of the item to be tested is the registration status, and the control module receives that there is a lid on the sample tube, the control module determines that the sample tube has not been opened, but the sample has not been tested yet. At this time, it is determined that the sample has not been tested, and the control module mobilizes the loading module to transfer the sample tube to the uncapping working position and mobilizes the uncapping module 400 to open the lid.

[0159] In the control method of the above sample processing device 10, the control module first makes a judgment on whether the sample tube is in the registration status and whether there is a lid according to the information received from the detection module 103, and transfers the sample tube to the corresponding uncapping or capping position according to the judgment result, which can reduce unnecessary operations and make the sample processing device 10 process the sample tube faster and more efficiently.

[0160] Specifically, the control method of the sample processing device 10 further includes obtaining user input information. The user input information at least includes the original lid requirement. The original lid requirement is whether the user needs to retain the original lid. If the user input information is that the original lid does not need to be retained to determine that there is no need to perform the operation of adding the original lid after the sample tube is opened, then after "mobilizing the loading module to transfer the sample tube to the uncapping working position and mobilizing the uncapping module to open the lid", the control module mobilizes the uncapping module or the capping module to move to the discard module to discard the original lid;

[0161] If the user input information is that the original lid needs to be retained to determine that the original lid needs to be added to the sample tube after opening the lid, then after "activating the loading module to transfer the sample tube to the lid-opening working position and activating the lid-opening module to open the lid", the control module activates the lid-covering module to move to the storage module to store the original lid.

[0162] In the control method of the above sample processing device 10, the control module first makes a judgment on whether the original lid needs to be added to the sample tube later according to the information received by the detection module 103, and disposes the lid of the sample tube according to the judgment result, which can effectively utilize the lid, making the sample processing device 10 more material-saving and cost-reducing in processing the sample tube.

[0163] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0164] The above-described embodiments merely represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
