Description

Technical Field

[0001] This application relates to the field of sample testing technology, and in particular to a sample holder for sample testing. Background Technology

[0002] With the development of precision medicine, medical immunoassay, as a core area of ​​in vitro diagnostics, is becoming increasingly sophisticated, placing new demands on the efficiency, stability, and clean transportation of samples.

[0003] Currently, the transportation method for sample testing involves using traditional stepper or servo motors to drive mechanical belts for transmission. The driving force mainly comes from the contact friction between the sample tray and the belt, which leads to wear and tear on both the sample tray and the belt over long periods of operation. To overcome the problems caused by belt transmission, some transportation methods have adopted electromagnetic drive. However, the sample tray is not compatible with both electromagnetic drive tracks and belt transmission tracks, limiting its applicability. Furthermore, the existing electromagnetic drive methods have poor motion stability of the sample tray, making them unsuitable for high-precision medical testing systems.

[0004] Therefore, how to improve the motion stability of the sample holder on the electromagnetic drive track and how to expand the applicability of the sample holder are technical problems that need to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a sample holder for sample testing that is compatible with both electromagnetic drive tracks and belt conveyor tracks, and has a stable motion effect in electromagnetic drive tracks, thereby adapting to high-precision medical testing systems.

[0006] To achieve the above objectives, this application provides a sample holder for sample testing, applied in a conveyor belt or electromagnetic track, comprising:

[0007] The body, used to hold the sample;

[0008] Magnets are symmetrically arranged on two opposite sides of the main body, and a force is generated between the magnets and the electromagnetic track to drive the main body to move;

[0009] A pulley is rotatably disposed on both sides of the body having the magnet. The pulley is rotatably connected to the body via a rotating shaft. The outer peripheral surface of the pulley protrudes from the side of the body to guide the body to move in the electromagnetic track.

[0010] The pulley is provided at least on the bottom surface of the main body. One end of the rotating shaft is fixedly connected to the bottom surface of the main body, and the other end extends toward the lower side of the main body and forms a support plane at the end. The pulley is rotatably disposed between the support plane and the bottom surface of the main body.

[0011] In some embodiments, there are at least four pulleys at the bottom of the body, and the four pulleys are distributed in pairs on both sides of the bottom of the body, and the pulleys roll and abut against the lower part of the electromagnetic track.

[0012] In some embodiments, the supporting planes of the plurality of pivots at the bottom of the body are located on the same horizontal plane.

[0013] In some embodiments, a frame is fixedly provided above the main body, and a fixed card seat is provided on the frame, and the sampling tube is placed in the fixed card seat.

[0014] In some embodiments, the pulley is provided between the frame and the body, one end of the rotating shaft is fixed to the frame, and the other end is fixed to the top surface of the body. The frame has a side opening for the pulley to be exposed, and the pulley rolls against the upper part of the electromagnetic track through the side opening.

[0015] In some embodiments, there are at least four pulleys on the top of the body, and the four pulleys are distributed in pairs on both sides of the top of the body.

[0016] In some embodiments, the body has protruding anti-detachment strips on both sides of the magnet, the anti-detachment strips extend along the movement direction of the body, the electromagnetic track has anti-detachment grooves that cooperate with the anti-detachment strips, the anti-detachment strips and the anti-detachment grooves are spaced apart, and the anti-detachment grooves prevent the sample holder from detaching from the electromagnetic track through the anti-detachment strips.

[0017] In some embodiments, the main body has receiving grooves on two opposite sides to accommodate the magnets, and the receiving grooves are provided with pads, which are located on the side of the corresponding magnet away from the electromagnetic track.

[0018] In some embodiments, a position feedback module is provided on the bottom surface of the body, and the position feedback module does not extend beyond the support plane.

[0019] In some embodiments, the position feedback module includes a permanent magnet and an RFID tag. The permanent magnet works in conjunction with the detection circuit of the electromagnetic track to collect the movement position of the body in real time, and the RFID tag stores sample information.

[0020] The beneficial effects of this application are that the sample holder can move within the moving magnetic field of an electromagnetic track by cooperating with its magnets, thus achieving electromagnetic drive. Furthermore, pulleys are provided on both sides of the sample holder, which roll and abut against the electromagnetic track, keeping the sides of the sample holder in contact with the track. This prevents the magnets from attracting to the track and assists the movement of the sample holder, providing guidance and making its movement within the electromagnetic track more stable. In addition, the rotating shafts on the bottom of the body form a support plane. The support plane formed by multiple rotating shafts allows the sample holder to be stably placed on a belt, thus adapting to belt-driven transport tracks and expanding the applicability of the sample holder.

Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 3 As shown, in this embodiment, a sample holder for sample testing is provided. The sample holder 1 can be applied to a conveyor belt or an electromagnetic track 2. The sample holder 1 includes a body 11, a magnet 12, and a pulley 15. The body 11 is the main bearing component and can be used to carry samples. The magnet 12 is symmetrically arranged on two opposite sides of the body 11. When the sample holder 1 is applied to the electromagnetic track 2, a drive coil 22 is provided on the electromagnetic track 2. Multiple drive coils 22 are symmetrically arranged on both sides of the body 11, and the positions of the drive coils 22 and the magnets 12 correspond. After three-phase alternating current with a certain phase difference is passed through different drive coils 22, they will be combined to form a moving magnetic field, thereby forming a force that pushes the magnets 12 to move in the moving magnetic field, realizing the transportation of the sample holder 1.

[0034] Among them, magnet 12 is a sinusoidal magnetized magnet 12, and drive coil 22 contains silicon steel structure, which can increase the intensity of electromagnetic field and improve heat dissipation. There can be multiple magnets 12 on each side of the body 11, such as two, three, four, etc., as long as the number and specifications of magnets on the two opposite sides of the body 11 are consistent, so that the sample holder 1 is subjected to the same force on both sides in the moving magnetic field, and the sample holder 1 moves more smoothly.

[0035] The pulleys 15 are rotatably mounted on the two opposite sides of the body 11 containing the magnets. Please refer to [reference needed]. Figure 2The pulley 15 is rotatably connected to the body 11 via the rotating shaft 16, and the outer peripheral surface of the pulley 15 protrudes from the side of the body 11. After protruding, it rolls against the electromagnetic track 2, thereby guiding the body 11 to move in a specified direction within the electromagnetic track 2, thus improving the motion stability of the sample holder 1.

[0036] Furthermore, at least one pulley 15 is provided on the bottom surface of the main body 11, and a corresponding rotating shaft 16 is also provided. One end of the rotating shaft 16 is fixedly connected to the bottom surface of the main body 11, and the other end extends downward toward the lower side of the main body 11 and forms a supporting plane 161 at the end. The pulley 15 is rotatably disposed between the supporting plane 161 and the bottom surface of the main body 11. When the sample tray 1 is suitable for belt conveyor, it can be stably placed on the conveyor surface of the belt through the supporting plane 161, thereby realizing the transportation of the sample tray 1.

[0037] In summary, the sample holder 1 of this application can move within the moving magnetic field of the electromagnetic track 2 by cooperating with the magnet 12 on it, thereby achieving electromagnetic drive. Furthermore, pulleys 15 are provided on both sides of the body 11 of the sample holder 1, which roll against the electromagnetic track 2, keeping the sides of the sample holder 1 in contact with the electromagnetic track 2. This prevents the magnet 12 from adhering to the electromagnetic track 2 and assists the movement of the sample holder 1, providing guidance and making its movement within the electromagnetic track 2 more stable. In addition, a supporting plane 161 can be formed on the bottom surface of the body 11 by the rotating shafts 16. The supporting plane 161 formed by multiple rotating shafts 16 allows the sample holder 1 to be stably placed on a belt, thus adapting to belt conveyor tracks and expanding the applicability of the sample holder 1.

[0038] To ensure the stability of the sample holder 1's movement within the electromagnetic track 2 and its placement on the belt, at least four pulleys 15 can be installed at the bottom of the main body 11, with each pulley 15 distributed in pairs on either side of the bottom of the main body 11. The four pulleys 15 are arranged in a rectangular pattern, forming a stable rectangular support structure, thus improving the stability of the rolling contact between the pulleys 15 and the electromagnetic track 2. Similarly, the four rectangular pulleys 15 correspond to four rectangularly distributed rotating shafts 16, and the support planes 161 on the four rotating shafts 16 together form a stable rectangular support structure, ensuring stable placement of the sample holder 1 on the belt. It should be noted that the four rotating shafts 16 should be located at the four apex corners of the bottom surface of the main body 11, so that the center of gravity of the sample holder 1 falls as close as possible to the center of the four rotating shafts 16, avoiding the problem of tipping over due to a shift in the center of gravity.

[0039] Furthermore, among the multiple rotating shafts 16 at the bottom of the body 11, their supporting planes 161 are all located on the same plane or on the same horizontal plane, so that the sample holder 1 can fit against the conveying surface of the belt, thereby improving the placement stability of the sample holder 1.

[0040] A frame 13 is located above the main body 11. Please refer to [reference needed]. Figure 1 The frame 13 is equipped with a fixing seat 14, in which the sampling tube can be placed. Furthermore, multiple spring clips are provided on the outer periphery of the fixing seat 14. After the sampling tube is placed into the fixing seat 14, the sampling tube can be fixed by the spring clip structure to ensure the stability of the sampling tube. Furthermore, the frame 13 can also be an integral structure with the main body 11.

[0041] The pulley 15 located on the upper side of the main body 11 is positioned between the frame 13 and the main body 11, and the corresponding rotating shaft 16 is also positioned between the frame 13 and the main body 11. Furthermore, one end of the rotating shaft 16 is fixed to the frame 13, and the other end is fixed to the top surface of the main body 11, with the pulley 15 rotatably mounted on the rotating shaft 16. A side opening 131 is provided on the frame 13 to allow the pulley 15 to protrude from the side of the main body 11 through the side opening 131, enabling the pulley 15 to roll and abut against the upper part of the electromagnetic track 2.

[0042] Similarly, four pulleys 15 can be provided on the upper side of the body 11, with two pulleys 15 distributed on both sides of the body 11, thus cooperating with the four pulleys 15 on the lower side of the body 11 to achieve a stable movement effect on the upper and lower sides of the body 11. It should be noted that the sample holder 1 and the electromagnetic track 2 in this application only use pulleys 15 for contact, which only plays a role in assisting movement in the left and right directions. In the up and down directions, the sample holder 1 and the electromagnetic track 2 do not contact each other, thereby avoiding contact friction between the sample holder 1 and the electromagnetic track 2.

[0043] In some embodiments, the body 11 has protruding anti-detachment strips 111 on both sides of the magnet, and the anti-detachment strips 111 extend along the movement direction of the body 11. Please refer to... Figure 1 and Figure 2 The electromagnetic track 2 is provided with an anti-detachment groove 21 that cooperates with the anti-detachment strip 111. The anti-detachment strip 111 extends into the anti-detachment groove 21, and the anti-detachment strip 111 interferes with the anti-detachment groove 21 in the vertical direction. Thus, the cooperation between the anti-detachment strip 111 and the anti-detachment groove 21 prevents the sample holder 1 from detaching from the electromagnetic track 2. When the sample holder 1 is under normal load, under the action of the moving magnetic field and the magnet 12, the sample holder 1 can be suspended at a certain height. At this time, the anti-detachment strip 111 is spaced apart from the anti-detachment groove 21 in both the vertical and horizontal directions, which can realize the sample holder 1 moving without contact with the electromagnetic track 2. When the sample holder 1 is overloaded or pressed up and down, causing the sample holder 1 to have an upward or downward tendency, the interference between the anti-detachment strip 111 and the anti-detachment groove 21 can prevent the sample holder 1 from detaching from the electromagnetic track 2.

[0044] On the two opposite sides of the main body 11, there are receiving grooves for accommodating magnets 12. There are pads 17 in the receiving grooves. The pads 17 are located on the side of the corresponding magnet 12 away from the electromagnetic track 2. They play the role of integrating the magnetic field circuit of the magnet 12 and can make the center of gravity of the sample holder 1 move closer to the driving center, making the movement more stable.

[0045] In addition, a position feedback module 18 is provided on the bottom surface of the main body 11. The position feedback module 18 does not extend beyond the support plane 161, ensuring that the position feedback module 18 will not affect the stable placement of the sample tray 1 on the belt. Furthermore, the position feedback module 18 includes a permanent magnet and an RFID tag. The permanent magnet and the detection circuit of the electromagnetic track cooperate to collect the movement position of the sample tray 1 in real time. The detection circuit includes a magnetic sensor and a corresponding control unit, etc., and detects the change in the direction of the magnetic field through a Hall element or a magnetoresistive sensor, outputting a sine / cosine electrical signal to obtain information such as the position and speed of the sample tray 1, which is provided to the motion control system for control. The RFID tag stores sample information, which facilitates sample tracking and information transmission between different detection modules in the fully automated sample production line module. The specific principle will not be elaborated here, but can be found in existing technology.

[0046] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

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