Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a sample tube rack clamping and transferring component and a processing module, and an automated diagnosis system. Background Art

[0002] Different types of sample tubes can be used in various scenarios, such as blood collection tubes, tissue fluid storage tubes, swab storage tubes, etc. Various types of sample tubes can hold different types of samples, and then use chemiluminescence, electrochemiluminescence, enzyme immunoassay, fluorescence amplification analysis and other analysis systems to achieve quantitative or qualitative detection of specific target substances, and ultimately achieve the goal of low-contamination in vitro diagnosis of ex vivo samples. With the continuous improvement of human living standards, more and more samples of various types need to be processed accurately and efficiently. The batch sample tube circulation with sample tube racks as the basic circulation unit has attracted the attention of more and more companies. On the one hand, the sample tube rack can transfer multiple sample tubes to different operating positions at one time to efficiently perform sample processing. On the other hand, there is no need to design an independent sample tube circulation cart. At the same time, a complex conflict coordination control mechanism is additionally configured to ensure that the entire system processes samples efficiently and accurately.

[0003] The sample tube rack, especially the single-row type, is suitable for flow-line or other types of highly integrated automated processing systems. Related systems can be seen in some large companies at home and abroad. The solution disclosed in CN102124348A is to arrange the sample tube rack receiving part, buffer part and recovery part and other areas in the horizontal plane, and configure the bus-type sample tube rack flow transfer and delivery mechanism to realize the circulation of the whole rack of sample tubes between different processing modules. The entire circulation process of the system is relatively long, resulting in low space utilization of the system. In the solution disclosed in JP5930957B2, the receiving part and the fault-tolerant part of the sample tube rack are arranged in front of the detection unit, and the sample tube rack is circulated in the storage part configured in the front by relying on the control method. The problem of high circulation space occupancy rate of the sample tube in this design is not solved, and the circulation of the entire sample tube rack is exposed outside the detection unit, which is low in reliability and poor in user experience for the operator. The solution disclosed in US20180313861A1 introduces a universal mechanical gripper to transfer sample tube racks. This design can avoid laying a circulation track and can transfer sample tube racks between different heights within a certain range. However, the universal gripper itself requires a larger storage space, and each unit needs to be configured as an open structure, which may lead to a higher risk of contamination of the entire system. Abbott's streamlined testing system and automated laboratory designed a single sample tube carrying trolley, and used more complex control technology to achieve a large number of trolleys without interference. The system is more complex and the circulation control is more complex. The MT8000 assembly line system of Mindray Medical, a domestic medical device giant, also adopts a single sample tube circulation solution similar to Abbott's, and is equipped with auxiliary structures suitable for quick U-turns and overtaking priority within the system. At the same time, it is equipped with complex circulation control methods to enable the entire system to operate efficiently and reliably. Although both whole-rack circulation and single-sample tube circulation have certain advantages, different types of systems require sufficient accommodation space to ensure the reliable circulation of sample tubes, and too much reserved space will make the entire system too large.

[0004] In order to perform the circulation operation of the sample tube rack in a confined space, it is necessary to design a new type of sample tube rack clamping and transfer assembly that can perform more complex transfer operations while not having a too long travel range, and further can be suitable for the scenario where the sample tube rack storage part is configured as a vertical layout to save space.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] As described in the background technology, various types of sample tubes need to be efficiently circulated in automated detection systems, especially in batch high-speed detection. Currently, different manufacturers have configured different types of sample tube circulation solutions. Some manufacturers use a circulation cart to carry a single sample tube to implement a single sample tube circulation solution. This design of the cart needs to be recycled. If a large number of sample tube racks are used for loading, a transfer component is also required to transfer the sample tubes in the sample tube rack to an independent circulation cart. This operation takes up a large space and the entire circulation path is complex and difficult to control. Another circulation solution based on the entire sample tube rack is also adopted by many manufacturers, but the circulation path of this design is complex and the space utilization rate is low. Therefore, it is urgent to develop a sample tube rack clamping and transfer component suitable for confined space to ensure efficient circulation.

[0035] Figure 1 : is a structural diagram of the clamping mechanism in the clamping transfer assembly provided by the present application. The clamping mechanism includes two opposing clamping units, a first clamping unit 101 and a second clamping unit 102, wherein the two clamping units have the same structure, and the two clamping units include a Z-shaped clamping jaw, wherein one end of the Z-shaped clamping jaw is fixedly connected to the moving rod of the clamping unit, and the other end is constructed to include a clamping jaw head of a preset width. In order to ensure that the clamping jaw head can better clamp the sample tube rack, a flexible buffer unit or other buffer unit can be configured on the clamping side of the clamping jaw head. The two moving rods of the clamping unit can be engaged and connected with the clamping mechanism body, and can be driven by the transmission gear rack structure to generate a relative movement that makes the two opposing clamping units approach or move away from each other. The driving motor and the corresponding transmission mechanism contained in the clamping mechanism body are not shown here. The clamping mechanism drives the two clamping units to approach or move away from each other from the opposite sides of the sample tube rack, thereby clamping or loosening the sample tube rack 100. Here, the sample tube rack 100 is shown as a single-row type sample tube rack including 8 sample tube receiving positions, and the opposite side is the length direction of the sample tube rack 100, so that the clamping unit can have a larger adjustment and adaptation space, ensuring that the sample tube rack can be clamped more reliably and tightly. The clamping mechanism 10 is fixedly connected with a sliding base plate 11 and a sliding connection block 12, where the sliding base plate 11 can be fixedly connected to the main body of the clamping mechanism 10 by screws or pins, and the sliding connection block 12 can be fixedly connected to the sliding base plate 11 in a similar manner, and at least one embedded slide groove 111 is configured on the sliding base plate 11, and two embedded slide grooves are shown here.

[0036] Figure 21 is a structural diagram of the connection between the top substrate and the clamping mechanism provided by the present application. Here, at least one interlocking groove 111 configured on the sliding substrate 11 is slidably connected with a corresponding number of interlocking rails 131 configured at the bottom of the top substrate 13, so that the clamping mechanism 10 can be driven to slide back and forth in the horizontal plane. The top substrate 13 is also connected to a vertical driving mechanism, which includes a vertical driving motor 141, whose output is connected to a vertical transmission screw 142, and the vertical transmission screw 142 is threadedly connected to a buffer substrate 143 fixedly connected to the top substrate 13. The top substrate 13 is also configured with at least one vertical groove 144, which is slidably connected to a vertical rail 145 fixed in a vertical plane. In this way, when the sample tube rack to be transferred is configured in the storage position including the baffle, the clamping mechanism can first be driven to approach the sample tube rack in the horizontal direction. When it moves to a suitable clamping position, the clamping claw mechanism can drive the opposing clamping units to approach and clamp the sample tube rack from both sides, and then the vertical drive motor 141 can be operated to drive the top substrate 13 to move upward in the vertical direction, and then the clamped sample tube rack can be lifted to a distance exceeding the height of the baffle to perform obstacle avoidance. In this embodiment, the number of vertical slide grooves 144 and the number of embedded slide grooves 111 are both 2, which can ensure that the vertical and horizontal movements are performed smoothly and with low resistance. The screw thread in the vertical drive mechanism can ensure that the vertical direction drive has a higher motion drive accuracy, and can ensure a more stable and reliable lifting drive, so that the sample tube rack transfer process is more reliable and does not need to reserve too much vertical reserved space at the transferred position.

[0037] Figure 3 1 is a diagram of the sliding drive structure of the clamp mechanism provided by the present application. A sliding drive structure of the clamp mechanism is arranged at the top of the top substrate 13 opposite to the bottom configuration side of the engaging slide rail 131, which includes a sliding drive motor 132, the motor output shaft is connected to the sliding drive wheel 133, a sliding driven wheel 135 is arranged at a preset distance from the sliding drive wheel 133, and a sliding transmission belt 134 is wound between the driving wheel 133 and the driven wheel 135. Here, the sliding transmission belt 134 can be a toothed synchronous transmission belt to ensure the accuracy of the movement position, and a sliding connection block 12 is fixedly connected to the lower side of the sliding transmission belt 134, so that when the sliding drive motor outputs clockwise or counterclockwise rotation, the sliding connection block 12 can drive the clamp mechanism 10 to reciprocate in the horizontal plane. The use of a pulley drive here can ensure the high-speed characteristics of the horizontal sliding motion drive, so that the sample tube rack can be transferred more quickly, and a vertical sensing unit 136 is also arranged, and a vertical sensor 137 is fixedly arranged at a predetermined height. This can be used as a position reference or limit position for the vertical drive movement. When the top substrate is driven vertically to a certain height, the sliding drive motor 132 can be controlled to operate to horizontally transfer the sample tube rack. The two drive mechanisms cooperate to efficiently and smoothly perform the sample tube rack transfer operation.

[0038] Figure 4 and Figure 5 1 is a state diagram of the clamping and transferring assembly provided by the present application transferring a sample tube rack. In this embodiment, the clamping and transferring assembly comprises a top substrate 13 and a bottom substrate 15 spaced apart from each other, and a vertical substrate is also included between the two, wherein the bottom substrate 15 can be integrally formed with the vertical substrate or fixedly connected as an integral structure, and a hanging ring structure can be configured on the top of the vertical substrate, and the clamping and transferring assembly can be connected to the counterweight part through a flexible holding member penetrating the hanging ring, so that the gravity of the assembly can be offset so that it can be driven with low resistance in a vertical plane to move to different heights to perform the sample tube rack transfer operation. The vertical drive motor 141 can be fixed on the vertical substrate, and a vertical slide rail 145 is also fixed on the vertical substrate. A reserved portion with a predetermined spacing is included between the top substrate 13 and the buffer substrate 143 to accommodate the redundant section of the threaded vertical lead screw 142 during the vertical drive process. The spacing between the top substrate 13 and the bottom substrate 15 can be changed by rotating the vertical drive motor 141. A component vertical drive motor 20 is also configured on the bottom substrate 15, and a plurality of component vertical slide grooves are also configured on the back of the vertical substrate, which can be slidably connected with the component vertical slide rail vertically fixed in the module, so that the vertical height of the component can be changed. The bottom substrate 15 is also provided with a sample tube rack receiving part, wherein the sample tube rack receiving part includes two sample tube rack receiving positions 161 and 162, and the sample tube rack receiving part can be driven by a receiving horizontal driving mechanism to move in a direction that is the same as or parallel to the horizontal reciprocating motion direction of the clamping claw in a horizontal plane, and the receiving horizontal driving mechanism includes a horizontal driving motor, whose output is connected to a horizontal transmission screw 153, and the horizontal transmission screw 153 is threadedly connected to the sample tube rack receiving part, so that the sample tube rack receiving part can also be driven to move in a horizontal plane. Here, the sample tube rack receiving part adopts a screw thread drive, and the sliding drive of the clamping claw mechanism adopts a pulley drive. The two types of transmission can respectively drive the sample tube rack receiving part and the clamping claw mechanism to slide different strokes in the horizontal plane, so that the transfer operation range can be expanded and the limited operation space can be effectively utilized. The two different types of transmission drives respectively meet the different transfer requirements of high-speed transfer and precise transfer, and the accuracy of the transfer position can be guaranteed when the sample tube rack is transferred at a high speed. Each of the sample tube rack receiving positions includes a transmission belt and a transmission belt drive motor 163, whose output shaft is connected to a first transmission gear, which is meshed with a second transmission gear 164, and a central shaft that can drive the transmission belt to move is connected to the center of the second transmission gear 164. Here, the central shaft can be fixedly connected to a roller that drives the transmission belt to move, thereby simultaneously driving the transmission belts of different sample tube rack receiving positions to move. In some special cases, a clutch transmission mechanism can also be configured so that the transmission belt drive motor 163 can drive the transmission belts of different operating positions to move in different time periods, which is not limited here.

[0039] Figure 6 and Figure 7 This is a state diagram of the clamping transfer assembly provided by the present application placing the sample tube rack at one of the sample tube rack receiving positions. As previously explained, the clamping claw mechanism 10 can be driven to clamp the sample tube rack from both sides when it is close to the sample tube rack, and then the vertical drive motor 141 drives the top substrate 13 to move upward a predetermined distance, so that the sample tube rack can cross the obstacle, and the sliding drive motor 132 can drive the clamping claw to move horizontally. In order to ensure that the sample tube rack can be smoothly transferred into the sample tube rack receiving part, the sample tube rack receiving part is also configured to be able to slide in the horizontal plane. Before or after the clamping claw mechanism 10 stops, the horizontal drive motor 151 can rotate clockwise or counterclockwise, and then the threadedly connected sample tube rack receiving part is moved horizontally through the horizontal screw 153, so as to adapt to the transfer range covered by the sliding drive mechanism of the clamping claw mechanism 10. When the two are aligned so that the sample tube rack can be located directly above one of the sample tube rack receiving positions, the vertical drive motor 141 rotates in the opposite direction to the previous direction. The top substrate 13 is moved downward by a preset distance, and the sample tube rack is placed on one of the sample tube rack receiving positions. The opposite clamping claw unit loosens the sample tube rack, and the horizontal drive motor 151 drives the sample tube rack receiving part to withdraw to the original position. Finally, the transmission belt drive motor 163 drives the transmission belt of the sample tube receiving position to move to output the received sample tube rack to other modules. The sample tube rack receiving position can also receive the processed sample tube rack, and then is driven to move horizontally, and cooperates with the sliding drive of the clamping claw mechanism to move the sample tube rack out of the sample tube rack receiving part. The whole process is similar to the previous moving in.

[0040] Figure 8 This is a state diagram of another sample tube rack receiving position provided by the present application. The sample tube rack here can be an emergency delivery channel, which does not need to be operated and transferred using a clamping transfer component, and can achieve differentiated treatment of different diagnosis and treatment priorities. Of course, it can also be used as an efficient flow solution for simultaneously delivering sample tube racks or a spare sample tube rack receiving position, which is not limited here.

[0041] Fig. 9The structure diagram of the sample tube rack processing module including the clamping and transferring assembly. The sample tube rack processing module includes a module body, on which a plurality of sample tube rack storage parts are arranged longitudinally, and is shown here as including 5 sample tube rack storage parts, which are marked as 30, 31, 32, 33, and 34 from top to bottom, and at least part of the sample tube rack storage parts are sample tube rack storage parts (here 30 and 31 can be sample tube rack storage parts), and the sample tube rack storage parts include storage buffer parts 301 and 311 and drawer placement parts 302 and 312 that can be detachably connected to the sample tube rack receiving drawer. A lifting assembly is also installed on the module body, and a sample tube rack clamping and transferring assembly is configured on the lifting assembly, and the lifting assembly can be driven to move up and down and be aligned with at least one of the plurality of sample tube rack storage parts in a horizontal plane. When the lifting assembly is driven to align with one of the sample tube rack storage parts, the sample tube rack clamping and transferring assembly can be driven to clamp the sample tube rack from the storage buffer part to the sample tube rack receiving part, and be driven by the conveyor belt to move and output. Of course, at least part of the sample tube rack storage part is the sample tube rack recovery part (here the sample tube rack recovery part at positions 32 and 33), and at least part of the sample tube rack storage part is the sample tube rack fault-tolerant part (here the sample tube rack fault-tolerant part at position 34). In terms of vertical position relationship, the sample tube rack receiving part is higher than the sample tube rack recovery part, the sample tube rack recovery part is higher than the sample tube rack fault-tolerant part, and the number of the sample tube rack receiving parts and / or the sample tube rack recovery parts is greater than the number of the sample tube rack fault-tolerant parts, and the sample rack recovery part and the sample tube rack fault-tolerant part can be configured with cache parts 321, 331 and 341 similar to the sample tube rack storage part, and are also configured with drawer placement parts 322, 332 and 342, which can cooperate with the clamping transfer component to transfer the sample tube rack from the sample tube rack receiving part to it, which will not be repeated here.
