Description

Technical Field

[0001] This utility model relates to the field of medical sampling instrument technology, and in particular to a sampling mechanism and sampling turntable device. Background Technology

[0002] In clinical testing, biological research, and other fields, smear preparation of blood, cytosolic fluid, and other samples is a fundamental and crucial pretreatment step. Automated sample processing systems, by integrating functions such as consumable handling, sample collection, and smear preparation, aim to replace traditional manual operations to improve preparation efficiency and result consistency. With the continuous increase in testing throughput demands, achieving multi-task parallel processing within limited equipment space has become a key technical challenge for improving the overall efficiency of automated systems.

[0003] In existing technologies, single-unit actuators with sampling and smearing functions are relatively mature. However, when multiple such mechanisms are combined to build parallel workstations, their inherent discrete structural layout makes it difficult to meet the requirements of high integration and high coordination in automation systems. Specifically, simple mechanical stacking not only leads to a bulky system structure and excessive space occupation, but also makes the drive and control circuits more complex. Furthermore, multiple independent mechanisms are prone to motion interference when working together. These problems collectively lead to a significant increase in system cost and a reduction in overall operational reliability. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sampling mechanism that can independently complete the combined actions of grasping consumables, collecting samples, and preparing smears at a single workstation, thereby improving space utilization efficiency and structural compactness, and reducing system operating costs.

[0007] It has at least the following beneficial effects: The gripping component is mounted on the base and can move up and down relative to the base. The gripping component can automatically grip the sampling cylinder and keep it in a stable vertical clamping state. The suction component is connected to the gripping component. It should be noted that the sampling cylinder has a hollow cylindrical structure with an opening at its lower end. When the gripping component holds the sampling cylinder and places it into the sample cup so that the bottom of the sampling cylinder contacts the liquid sample, the suction component uses the generated negative pressure to draw the sample through the opening into the sampling cylinder, thereby completing the sample collection. The smearing component is fixed on the base, and its output end is connected to the gripping component for transmission. The smearing component can drive the gripping component to reciprocate in the horizontal plane, thereby enabling the bottom of the sampling cylinder to perform a reciprocating smearing action on the glass slide, and finally uniformly and completely coating the sample in the sampling cylinder onto the surface of the glass slide. The technical solution of this utility model integrates multiple discrete functional modules into a compact structure, realizing the complete set of composite actions of grasping consumables, collecting samples and preparing smears independently and continuously by a single device. This not only simplifies the overall structure of the equipment and reduces manufacturing costs and control complexity, but also reduces the handover and waiting time between processes through optimized action flow, effectively improving the work efficiency and smoothness of a single workstation.

Detailed Implementation

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 3 This utility model discloses a sampling mechanism, including a base 1, a gripping component 2, a suction component 3, and a smearing component 4. The gripping component 2 is vertically mounted on the base 1 and is configured to grip a sampling cylinder 10. The suction component 3 is connected to the gripping component 2 and is configured to extract the sample into the sampling cylinder 10. The smearing component 4 is mounted on the base 1 and is connected to the gripping component 2. The gripping component 2 is vertically mounted relative to the smearing component 4 and is configured to drive the gripping component 2 to reciprocate in a horizontal plane.

[0025] like Figure 1As shown, the gripping component 2 is mounted on the base 1 and can move up and down relative to the base 1. The gripping component 2 can automatically grip the sampling cylinder 10 and keep it in a stable vertical clamping state. The suction component 3 is connected to the gripping component 2. It should be noted that the sampling cylinder 10 is a hollow cylindrical structure with an opening at its lower end. When the gripping component 2 holds the sampling cylinder 10 and places it into the sample cup so that the bottom of the sampling cylinder 10 contacts the liquid sample, the suction component 3 uses the generated negative pressure to draw the sample through the opening into the sampling cylinder 10, thereby completing the sample collection. The smearing component 4 is fixed on the base 1, and its output end is connected to the gripping component 2 for transmission. The smearing component 4 can drive the gripping component 2 to reciprocate in the horizontal plane, thereby enabling the bottom of the sampling cylinder 10 to perform a reciprocating smearing action on the glass slide, and finally uniformly and completely coating the sample in the sampling cylinder 10 onto the surface of the glass slide.

[0026] The technical solution of this utility model integrates multiple discrete functional modules into a compact structure, realizing the complete set of composite actions of grasping consumables, collecting samples and preparing smears independently and continuously by a single device. This not only simplifies the overall structure of the equipment and reduces manufacturing costs and control complexity, but also reduces the handover and waiting time between processes through optimized action flow, effectively improving the work efficiency and smoothness of a single workstation.

[0027] In some specific embodiments of this utility model, the gripping component 2 is lifted and lowered by the lifting component 13. The lifting component 13 can be a cylinder, a lead screw and nut drive pair, or other components capable of lifting and lowering. Further details will not be provided here.

[0028] In some specific embodiments of this utility model, the application component 4 can adopt various structural forms to realize its driving function. For example, it can adopt a combination of crank connecting rod and linear guide rail, with the crank rotating through a motor, and the circular motion being converted into the precise reciprocating motion of the gripping component 2 along the linear guide rail through the connecting rod; or, it can adopt a cam rocker arm mechanism, using a cam with a specific profile to push the rocker arm to swing, thereby driving the gripping component 2 to move according to a predetermined law; or, it can adopt a gear 411 and rack 412 transmission, with the gear 411 driven by a motor mounted on the base 1, causing it to roll along the fixed rack 412, thereby realizing the linear displacement of the gripping component 2. For scenarios requiring high precision, a linear motor or voice coil motor can also be directly used as the driving source to achieve high-precision reciprocating motion of the gripping component 2 through direct drive.

[0029] In some specific embodiments of this utility model, a stirring component 5 is also included. The stirring component 5 is connected to the gripping component 2 and is configured to drive the gripping component 2 to rotate around a vertical axis. The stirring component 5 is drively connected to the gripping component 2, and can drive the gripping component 2 and the sampling cylinder 10 it holds to rotate around a vertical central axis. This rotational action can agitate the liquid in the sample cup before sample collection, which is particularly suitable for resuspending diluted samples that have precipitated, thereby ensuring the representativeness and uniformity of the collected samples and improving the accuracy of subsequent test results.

[0030] like Figure 1 In the specific embodiment shown, the stirring assembly 5 includes a stirring motor 51 and a drive shaft 52. The stirring motor 51 is fixed to the gripping assembly 2 by a mounting base, and its output shaft is connected to the gripping assembly 2 by a coupling to directly drive the gripping assembly 2 to rotate around its own axis.

[0031] In some other specific embodiments of this utility model, the stirring component 5 can also be a vibration generator. The vibration generator is mechanically coupled to the gripping component 2, which can generate high-frequency micro-amplitude mechanical vibration and transmit the vibration to the gripping cylinder 21 and the sampling cylinder 10 it holds, thereby efficiently disturbing the sample, so that the precipitate is quickly resuspended and reaches a uniformly mixed state.

[0032] In some specific embodiments of this utility model, a discharge assembly 6 is also included. The discharge assembly 6 is connected to the gripping assembly 2 and is configured to peel the sampling cylinder 10 off the gripping assembly 2.

[0033] like Figure 1 As shown, the unloading component 6 is connected to the gripping component 2. It is configured to reliably peel the used sampling tube 10 from the gripping component 2 through specific mechanical actions after the coating process is completed, thereby realizing the automatic unloading of consumables and avoiding manual intervention. This not only ensures the automation and continuity of the entire process, but also effectively prevents the risk of cross-contamination of samples due to the residue of the sampling tube 10, further improving the automation level and operational safety of the equipment.

[0034] In some other embodiments of this utility model, the sampling mechanism may not be equipped with a separate unloading component 6, and consumables may be replaced manually. In this simplified design, after the coating process is completed, the control system can issue a prompt signal to notify the operator, who can then manually remove the used sampling cylinder 10 and replace it with a new one. The equipment can then continue to execute subsequent processes, making it particularly suitable for cost-sensitive or low-frequency applications.

[0035] In some specific embodiments of this utility model, the gripping component 2 includes a gripping cylinder 21, which is vertically mounted on the base 1. The outer diameter of the gripping cylinder 21 is adapted to the inner diameter of the sampling cylinder 10. A sealing member 211 is sleeved on the lower end of the gripping cylinder 21. The sealing member 211 is configured to grip the sampling cylinder 10 and form a reliable seal when it fills the gap between the gripping cylinder 21 and the sampling cylinder 10.

[0036] like Figure 2 and Figure 3 As shown, the gripping cylinder 21 is vertically mounted on the base 1, and its outer diameter is tightly fitted with the inner diameter of the sampling cylinder 10. To achieve reliable gripping and sealing, an annular sealing element 211 is fitted around the lower end of the gripping cylinder 21. When the gripping cylinder 21 performs a gripping action, its lower end extends into the sampling cylinder 10, and the sealing element 211 undergoes the expected elastic deformation due to the radial compression of the inner wall of the sampling cylinder 10. It should be noted that the deformation of the sealing element 211 achieves a dual function. After deformation, a huge static friction force is generated between the outer circumferential surface of the sealing element 211 and the inner wall of the sampling cylinder 10. This friction force is sufficient to overcome the weight of the sampling cylinder 10 itself and the inertial force generated during its movement, thereby firmly gripping the sampling cylinder 10 and making it move synchronously with the gripping cylinder 21. On the other hand, the elastic deformation of the seal 211 fills the gap that may exist between the outer wall of the gripping cylinder 21 and the inner wall of the sampling cylinder 10, thereby forming a seal between the outer wall of the gripping cylinder 21 and the inner wall of the sampling cylinder 10. As a result, when the subsequent suction component 3 generates negative pressure, the sample can be efficiently and smoothly drawn into the sampling cylinder 10.

[0037] Specifically, multiple seals 211 may be provided, and multiple seals 211 are arranged sequentially along the axis of the gripping cylinder 21. They are preferably made of materials with good elasticity and wear resistance, including but not limited to silicone rubber, fluororubber or polyurethane.

[0038] In other specific embodiments of this utility model, the gripping component 2 can adopt various structural forms to realize its clamping function. These implementation methods can be flexibly selected according to the material specifications of the sampling cylinder 10, the usage environment, and cost requirements. Specifically, a mechanical gripper structure is adopted, which includes at least two radially movable gripper petals and is connected to the drive source through a linkage mechanism to realize active clamping and release; or, a pneumatic clamping scheme is adopted, which uses multiple ventilation holes provided in the wall of the gripping cylinder 21 to make the inner wall of the sampling cylinder 10 and the outer wall of the gripping cylinder 21 fit tightly together by using the principle of negative pressure adsorption.

[0039] In some specific embodiments of this utility model, the output end of the suction component 3 is connected to the gripping cylinder 21. The suction component 3 draws air from the sampling cylinder 10 through the gripping cylinder 21 to drive the sample into the sampling cylinder 10.

[0040] like Figure 2and Figure 3 As shown, the output end of the suction component 3 is connected to the upper end of the gripping cylinder 21 via a connecting pipe, thus forming a closed negative pressure suction system. When the gripping component 2 lowers the sampling cylinder 10 and immerses the opening at the bottom of the sampling cylinder 10 into the liquid sample to be collected, the sealing element 211 has formed a reliable seal between the gripping cylinder 21 and the sampling cylinder 10. At this time, the suction component 3 is activated, serving as the power source of the system. It rapidly extracts air from the continuous cavity from the gripping cylinder 21 to the bottom opening of the sampling cylinder 10 through suction, thereby creating a negative pressure within it. Under atmospheric pressure, the external liquid sample is continuously and smoothly forced into the cavity through the opening at the bottom of the sampling cylinder 10 until the preset collection volume is reached.

[0041] It should be further explained that the suction component 3 is not an independent and single-function sampling module. Instead, it achieves the dual function reuse of "physical gripping" and "fluid channel" through the existing mechanical structure of the gripping cylinder 21. This means that the gripping cylinder 21 itself serves as both a robotic arm that performs the gripping action and a key pipeline for negative pressure transmission. As a result, the entire device does not need to introduce additional, dedicated suction nozzles or complex fluid pipeline switching mechanisms for the sampling function, further simplifying the mechanical structure and control logic.

[0042] In some specific embodiments of this utility model, the suction component 3 adopts a syringe-type structure. The piston 32 is driven by the suction motor 31 to reciprocate in the cylinder. When the piston 32 retracts, a negative pressure is formed in the gripping cylinder 21 to extract the sample. When it is pushed forward, the sample can be discharged.

[0043] In other specific embodiments of this utility model, the suction component 3 can adopt various structural forms to achieve its suction function. For example, a miniature vacuum pump can be used as a power source, connected to the upper end of the gripping cylinder 21 through a flexible pipeline to form a closed negative pressure system. The suction function can be precisely controlled by controlling the start and stop of the vacuum pump. Alternatively, a Venturi effect scheme can be adopted, utilizing the negative pressure effect generated when compressed air flows through a variable diameter pipe, and the suction function can be achieved by controlling the opening and closing of the air path through a solenoid valve. It should be noted that any equipment or device that can achieve the function of suctioning air inside the gripping cylinder 21 to form a negative pressure falls within the protection scope of the suction component 3 of this utility model.

[0044] In some specific embodiments of this utility model, the unloading assembly 6 includes an unloading plate 61, which is sleeved on the gripping cylinder 21. The unloading plate 61 can be raised and lowered relative to the gripping cylinder 21, and the unloading plate 61 is located above the sealing member 211.

[0045] like Figure 2 and Figure 3As shown, the unloading plate 61 has a through hole, the inner diameter of which matches the outer diameter of the gripping cylinder 21, so that the unloading plate 61 is sleeved on the outside of the gripping cylinder 21 like a sleeve. The unloading plate 61 is positioned above the sealing member 211 and can move independently and controllably relative to the gripping cylinder 21. Thus, when the coating process is completed and the used sampling cylinder 10 needs to be discarded, the unloading plate 61 moves downward along the outer wall of the gripping cylinder 21. When the bottom end of the descending unloading plate 61 contacts and abuts against the upper end face of the sampling cylinder 10, it applies a continuous and uniform downward thrust, thereby overcoming the static friction between the sealing member 211 and the inner wall of the sampling cylinder 10. Without damaging the components, the sampling cylinder 10 is smoothly and reliably peeled off from the end of the gripping cylinder 21, realizing automated unloading.

[0046] In other specific embodiments of this utility model, the unloading assembly 6 can adopt various structural forms to achieve its function. For example, it can adopt a mechanical clamping unloading method. By setting a pair of openable and closable grippers, the sampling cylinder 10 is clamped at the unloading station, and the gripping assembly 2 moves upward to achieve separation. It should be noted that any equipment or device that can separate the sampling cylinder 10 from the end of the gripping cylinder 21 falls within the protection scope of the unloading assembly 6 of this utility model.

[0047] It should be noted that the unloading plate 61 can be driven by linear motion components such as cylinders and lead screw nut drive pairs, which will not be elaborated further here.

[0048] In some specific embodiments of this utility model, a first fixed seat 11 and a second fixed seat 12 are also included. The first fixed seat 11 is connected to the output end of the coating component 4, and the coating component 4 can drive the first fixed seat 11 to swing back and forth on the horizontal plane. The second fixed seat 12 can be raised and lowered on the first fixed seat 11. The gripping component 2, the suction component 3, the stirring component 5 and the unloading component 6 are all arranged on the second fixed seat 12.

[0049] like Figure 1 As shown, the application component 4 is fixedly mounted on the base 1, and the application component 4 is drivenly connected to the first fixed seat 11 through its output end. In this specific embodiment, the application component 4 uses a gear 411 and rack 412 transmission mechanism to achieve power transmission. Specifically, the application component 4 includes an application motor 41 fixed to the base 1, with a gear 411 mounted on its output shaft, and a rack 412 meshing with the gear 411 on the first fixed seat 11. When the application motor 41 starts, the gear 411 rotates and drives the rack 412, thereby driving the entire first fixed seat 11 and all the components carried on it to move linearly back and forth in the left and right direction, thus realizing the application function.

[0050] Furthermore, the first fixed base 11 is composed of a T-shaped integrated structure, mainly including a vertical panel and a horizontal panel. The vertical panel serves as the main load-bearing surface, and its front end is used to install the first guide component 7. The horizontal panel is located at the rear end of the vertical panel and is connected to it at a perpendicular angle. Specifically, the upper or lower surface of the horizontal panel is slidably connected to the base 1 where the applicator motor 41 is located through the third slide rail 111 and the third slider 112, so that the entire first fixed base 11 and all the components it supports can perform linear reciprocating motion relative to the fixed base 1 through the slide rail and slider mechanism, thereby accurately converting the rotational output of the applicator motor 41 into a horizontal applicator action.

[0051] The second fixed base 12 is vertically mounted on the first fixed base 11, and the suction component 3, stirring component 5, and gripping component 2 are all integrated and mounted on the second fixed base 12. Thus, the suction component 3, stirring component 5, and gripping component 2 can perform horizontal spreading movements with the first fixed base 11, and can also achieve independent lifting movements through the second fixed base 12. The various movement dimensions do not interfere with each other and work together efficiently.

[0052] Specifically, the second fixed seat 12 can be driven by linear motion components such as cylinders and lead screw nut drive pairs, which will not be described in detail here.

[0053] Furthermore, the suction component 3, the stirring component 5, and the gripping component 2 are coaxially integrated on the second fixed base 12 from top to bottom. Specifically, the output end of the suction component 3 is located at the top, and it extends downward through a connecting pipe. This pipe passes through the internal hollow area of ​​the stirring component 5 and the corresponding through hole on the second fixed base 12 in sequence, and finally maintains air passage communication with the upper end of the gripping cylinder 21 located at the bottom. This allows the negative pressure airflow channel to be cleverly built into the stirring component 5, thus forming a compact and well-sealed closed negative pressure suction system.

[0054] It should be further explained that, structurally, the three independent functional modules responsible for rotation, suction, and gripping overlap in space, which greatly saves horizontal installation space and is the core design for achieving equipment miniaturization; functionally, it ensures that the negative pressure suction function can continue to work without being affected, regardless of whether the gripping component 2 is in any position of lifting or stirring, thereby achieving decoupling and synergy between motion function and sampling function.

[0055] In some specific embodiments of this utility model, a first guide component 7 is also included. The first guide component 7 is connected to the first fixed seat 11 and the first guide component 7 is connected to the second fixed seat 12. The first guide component 7 is configured to guide the second fixed seat 12 to move vertically relative to the first fixed seat 11.

[0056] like Figure 3As shown, the first guide component 7 includes a first slide rail 71 and a first slider 72. The first slide rail 71 is fixedly installed on the first fixed base 11, and the first slider 72 is connected to the second fixed base 12. The first slider 72 moves along the direction limited by the first slide rail 71, thereby precisely guiding the second fixed base 12 to perform stable vertical lifting and lowering movements relative to the first fixed base 11, providing reliable guidance for the vertical displacement of the core functional module.

[0057] In some specific embodiments of this utility model, a second guide component 8 is also included. The second guide component 8 is connected to the first guide component 7 and to the unloading plate 61. The second guide component 8 is configured to guide the unloading plate 61 to move vertically relative to the gripping cylinder 21.

[0058] like Figure 3 As shown, the second guide assembly 8 includes a second slide rail 81 and a second slider 82. The second slide rail 81 is integrated with the first slider 72, and the second slider 82 is connected to the unloading plate 61. Thus, the second slider 82 moves along the direction restricted by the second slide rail 81, thereby precisely guiding the unloading plate 61 to move vertically relative to the gripping cylinder 21, ensuring that it will not deviate or jam when performing the unloading action, so as to smoothly and reliably peel the sampling cylinder 10 from the gripping cylinder 21.

[0059] Reference Figures 1 to 4 This utility model discloses a sampling turntable device, including a frame 9 and multiple sampling mechanisms evenly distributed along the circumference of the frame 9. The frame 9 serves as the supporting foundation for the entire device, and the multiple fully functional sampling mechanisms are mounted on their respective bases 1. Specifically, these bases 1 are rotatably mounted on the frame 9 via a rotating mechanism 91. The rotating mechanism 91 can be a bearing or a slewing bearing structure, or other mechanism capable of rotation, which will not be further elaborated here. This circumferentially uniform layout allows each sampling mechanism to sequentially pass through different working positions as it rotates, thus forming an efficient, continuous, multi-station parallel processing system, providing a reliable hardware foundation for high-throughput sample processing.

[0060] The following is based on Figure 4 The structure shown further illustrates the working principle of this sampling turntable device.

[0061] In this specific embodiment, the sampling turntable device is equipped with three sampling mechanisms. These three mechanisms are uniformly fixed circumferentially to the output end of the rotating mechanism 91 and rotate synchronously and intermittently with it. Each of these three sampling mechanisms is precisely positioned at one of three functional stations: station one corresponds to the consumable gripping station, station two corresponds to the sampling station, and station three corresponds to the coating station. The complete working process and principle of this sampling turntable device are as follows: After the device is started, the rotating mechanism 91 drives the three sampling mechanisms to rotate, causing one of the sampling mechanisms to reach station one. At station one, the gripping component 2 of the sampling mechanism descends under the action of the lifting component 13, accurately grabbing an empty sampling cylinder 10 from the consumables compartment below. Then, the rotating mechanism 91 drives the sampling mechanism carrying the empty sampling cylinder 10 to rotate to station two. At station two, the gripping component 2 descends again, immersing the bottom opening of the sampling cylinder 10 into the sample cup containing the liquid sample. At the same time, the suction component 3 is activated, creating a negative pressure in the gripping cylinder 21 and the sampling cylinder 10 through the connecting pipe that runs through the stirring component 5, drawing a quantitative amount of liquid sample into the sampling cylinder 10 to complete the collection. It should be noted that if the sample needs to be mixed, the stirring component 5 can drive the gripping cylinder 21 and the sampling cylinder 10 to rotate at high speed to achieve stirring of the sample in the cup. The sampling mechanism, having completed sampling, then rotates to station three. At station three, the coating component 4 drives the entire first fixed seat 11 and its second fixed seat 12 in a horizontal reciprocating linear motion. Simultaneously, the gripping component 2 descends in a timely manner, causing the bottom of the sampling cylinder 10 to contact the surface of the glass slide, and uniformly coating the sample inside the cylinder onto the glass slide during the horizontal reciprocating motion. After the coating action is completed, the unloading component 6 is activated, and the unloading plate 61, fitted onto the gripping cylinder 21, moves downward under the constraint of the second guide component 8, smoothly pushing the used sampling cylinder 10 off the gripping cylinder 21 into the waste bin. Afterward, the sampling mechanism is in an unloaded state and continues to rotate with the turntable back to the beginning of a new work cycle at the station.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
