Description

Technical Field

[0001] This utility model relates to the field of sample testing technology, and in particular to a sample bottle opening device, a sampling device, and a three-dimensional structure testing device. Background Technology

[0002] In laboratory sample testing, the opening and injection of sample vials are crucial steps in ensuring the accuracy of experimental results. Sample vials typically employ clamp caps, screw caps, or bayonet caps, and their sealing performance directly affects the stability of the sample and the reliability of the injection process. Screw caps secure the septum with mechanical tightening force, suitable for most experimental needs. Sample vials are often made of chemically inert high borosilicate glass or temperature- and corrosion-resistant polypropylene plastic to suit the chemical properties of different samples and experimental conditions. Before injection, the cap seal must be strictly checked to prevent sample evaporation or septum debris from falling off due to a loose cap. Simultaneously, the sample filling volume must be controlled to less than two-thirds of the vial volume to prevent negative pressure from affecting injection accuracy. During injection, the cap must be tightened using a capping tool or manually to ensure a smooth and secure fit of the septum, avoiding over-tightening that could deform or loosen the septum.

[0004] CN219217514U discloses an automatic bottle cap screwing device, which includes a base plate, a robotic arm on the base plate, a cap screwing assembly on one side of the robotic arm, and a bottle cap placement assembly on one side of the cap screwing assembly; the cap screwing assembly includes a first gripper, the first gripper being rotatably connected to a turntable, and the end of the turntable away from the first gripper being connected to a motor; the motor, the first gripper, and the robotic arm are all connected to a control system.

[0005] The existing technology suffers from one or more of the following problems: insufficient adaptability to sample vials of different sizes, making it difficult to conveniently limit and stably place sample vials of different sizes on a horizontal plane; poor limiting effect on the sample vial body during the opening process, which easily leads to the sample vial rotating within the placement space, affecting the stability of the capping operation; deficiencies in the flexibility of the sample vial clamping mechanism in multi-dimensional movement, making it difficult to efficiently transfer the sample vial from the placement area to a fixed position and perform accurate capping operations; in addition, the existing fully automated sample injection system cannot guarantee the coordinated execution of capping and sample injection operations, resulting in low detection efficiency.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not possess the features of these prior art. On the contrary, this utility model already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes a sample bottle opening device, a sampling device, and a three-dimensional structure detection device to solve at least some of the aforementioned technical problems.

[0008] In a first aspect, this utility model discloses a sample bottle opening device, comprising: a driving mechanism, a capping mechanism, a fixing mechanism, and a tray mechanism. The tray mechanism's support module includes several modular placement racks, which suspend the sample bottles placed on them. The capping mechanism grips the sample bottles, allowing them to move in multiple dimensions under the drive of the driving mechanism, and transfers the sample bottles placed on the tray mechanism to the fixing mechanism. The fixing mechanism's bottle body support plate supports the bottom of the sample bottle and clamps it from opposite sides using bottle-gripping claws, thus limiting the bottle body. When the sample bottle body is limited by the fixing mechanism, the capping mechanism's opening claws tighten to limit the bottle cap, and the opening motor drives the opening claws to rotate the bottle cap.

[0009] According to a preferred embodiment, the drive mechanism includes a first drive unit and a second drive unit arranged perpendicularly to each other on the same horizontal plane, and a third drive unit perpendicular to both. A first movable frame of the first drive unit arranged along the X direction is mounted on the frame, a second movable frame of the second drive unit arranged along the Y direction is mounted on the first movable slide of the first drive unit, and a third movable frame of the third drive unit arranged along the Z direction is mounted on the second movable slide of the second drive unit.

[0010] According to a preferred embodiment, the first drive unit includes a first drive motor, a first lead screw nut, a first ball screw, a first movable slide, and a first limit switch disposed on a first movable frame. The first drive motor is coaxially connected to the first ball screw through a first coupling. The first lead screw nut is fixedly connected to the first movable slide. The first movable slide forms a sliding pair with the first movable frame through a guide rail slider.

[0011] According to a preferred embodiment, the second drive unit includes a second drive motor, a second coupling, a second movable slide, a second limit switch, and a second lead screw nut, all mounted on the second movable frame. The second drive motor is connected to the second lead screw nut via the second coupling. The second lead screw nut is fixed to the bottom of the second movable slide via a flange. The second movable slide forms a sliding pair with the second movable frame via a guide rail slider.

[0012] According to a preferred embodiment, the bottle-opening claw of the capping mechanism installed on the third moving slide of the third drive unit is connected to the bottle-opening motor through a capping nut, and the bottle-opening claw defines the accommodating space of the bottle cap through multiple claw heads.

[0013] According to a preferred embodiment, the fixing mechanism uses a finger electric cylinder to drive the bottle gripper to adjust the opening and closing degree of the gripper pliers, so as to limit or release the bottle body of the sample bottle. The inner side of the gripper pliers of the bottle gripper is provided with a groove corresponding to the curvature of the sample bottle body, and a resistance layer is provided on the surface of the groove to prevent the sample bottle from rotating in the placement space by friction.

[0014] According to a preferred embodiment, the tray mechanism includes a fixed plate for limiting the placement area of ​​the support module, and placement racks are arranged side by side on the fixed plate. The placement racks include a support frame and a placement platform. The top of the support frame is provided with a perforated plate with a perforated plate structure. The support frame is installed at both ends of the placement platform so that the placement platform is suspended above the fixed plate.

[0015] In a second aspect, this utility model discloses a sampling device, which is equipped with the aforementioned sample bottle opening device and further includes a sample injection mechanism mounted on a frame. The sample injection mechanism includes a liquid aspirator with a sample injection needle and a liquid level detector. The sample injection mechanism can be connected to a drive mechanism, thereby enabling it to perform multi-dimensional motion under the drive of the drive mechanism. The drive mechanism includes at least two third drive parts, such that one of the third drive parts is used to connect to a capping mechanism, and the other third drive part is used to connect to the sample injection mechanism.

[0016] According to a preferred embodiment, the sampling device further includes a waste liquid treatment mechanism. The discharge section and the cleaning section of the waste liquid treatment mechanism can both be configured as vertically placed columnar tubes with an opening at the top with an annular edge. At least one port is opened on the side wall of the cavity. The discharge section has a waste liquid port for connecting to the waste liquid pipe; the cleaning section has a waste liquid port for connecting to the waste liquid pipe and a cleaning liquid port for connecting to the cleaning liquid pipe. The two ports are independent of each other, and the cleaning liquid port is higher than the waste liquid port in the Z direction.

[0017] In a third aspect, this utility model discloses a three-dimensional structure detection device, which is equipped with the aforementioned sampling device and also includes an analytical detection instrument. The analytical detection instrument is connected to the sample injection mechanism of the sampling device through a conduit, so that after the sample injection mechanism draws the liquid to be tested from the sample bottle with the cap open, it can transfer the drawn liquid to the analytical detection instrument.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0019] This utility model's sample vial opening device significantly improves the compatibility and operational stability of laboratory sample processing through the coordinated design of a modular tray structure and an adjustable clamping system. The tray mechanism utilizes a standardized support frame combined with a perforated plate; by adjusting the perforated plate size, it can accommodate sample vials of different sizes without requiring reconstruction of the entire support module, thus reducing structural modification costs due to differences in container specifications. Simultaneously, the suspended design of the support frame, combined with the perforated plate's limiting function, provides stable constraint on the sample vials in the horizontal direction, avoiding the tilting risk caused by direct contact in traditional trays. The combination of the vial body support plate and the gripping claws in the fixing mechanism further enhances clamping reliability: the support plate supports the bottom of the vial to distribute pressure, while the groove design and resistance layer of the claws, by matching the curvature of the vial body and increasing friction, effectively suppresses deflection or slippage of the sample vial during clamping. Furthermore, the integration of the capping mechanism with the 3D drive system allows the bottle opening operation to break through the limitations of the traditional two-dimensional plane. The opening claws can move in conjunction along the X, Y, and Z directions, precisely aligning with the sample bottle cap and completing the loosening / tightening action, avoiding the problem of poor contact between the claws and the bottle cap caused by limited movement paths. This structural design is particularly suitable for high-throughput experimental scenarios, shortening the overall operation cycle by reducing manual intervention and mechanical adjustment steps.

[0020] This invention's sampling device and three-dimensional structure detection device, through the vertical integration of the sample introduction mechanism and drive system, and the separate layout of the waste liquid treatment module, improve detection efficiency while optimizing the safety and cleanliness of the experimental environment. The sample introduction mechanism uses a vertical mounting block connected to the third drive unit, allowing the aspirator to accurately move downwards along the Z-direction to a predetermined depth inside the sample vial, avoiding the risk of needle collision or liquid splashing caused by height deviations in traditional horizontal movement mechanisms. The rigid connection design of the mounting block ensures the aspirator maintains stable posture during dynamic movement. The waste liquid treatment mechanism separates the discharge section and the cleaning section into independent chambers. The layered arrangement of the cleaning fluid inlet and waste fluid inlet along the Z-direction effectively blocks the reverse flow of cleaning fluid and waste liquid, preventing cross-contamination. The cleaning section achieves circulating rinsing through an independent liquid supply channel. Combined with the annular edge design of the top opening of the chamber, it facilitates needle insertion while reducing the possibility of liquid spillage. The integration of a single microcoder further enhances the traceability of sample management. The overall structure, through the standardized interface design of functional modules, supports seamless connection of each link in the testing process, reduces the complexity of equipment maintenance, and extends service life.

Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] According to a preferred embodiment, the present invention discloses a sample bottle opening device, which includes: a frame 100 and several functional mechanisms, wherein the frame 100 can be disposed on an operating platform 900, the driving mechanism 200 and the capping mechanism 300 can be disposed on the frame 100, and the fixing mechanism 400 and the tray mechanism 500 can be disposed on the operating platform 900. Figure 1 and Figure 2 The diagram below, excluding the sample injection mechanism 600, shows the structure of the sample bottle opening device.

[0039] Preferably, such as Figure 2 As shown, the tray mechanism 500 may include a fixed plate 510 and a support module 520 placed on the fixed plate 510. The fixed plate 510 may be disposed on an operating table to limit the placement area of ​​the support module 520. Preferably, the support module 520 may include a plurality of modular placement racks 530, which can be placed side by side on the fixed plate 510. Further, the placement rack 530 may include a support frame 531 and a placement platform 532. The support frame 531 may be installed at both ends of the placement platform 532 so that the placement platform 532 can be suspended above the fixed plate 510. More preferably, the support frame 531 may be installed on the short side of the placement platform 532, and the sample bottles 540 may be arranged along the long side of the placement platform 532 so that the sample bottles 540 can also be suspended in a row above the fixed plate 510. Preferably, the four corners of the support frame 531 can be chamfered, and protective protrusions can also be provided on the outer sides of the four corners of the support frame 531. Preferably, a perforated plate 533 can be provided at the top of the support frame 531. The perforated plate 533 is a plate-like structure with several holes. The size of the holes can be determined based on the specifications of the sample bottle 540, so that the sample bottle 540 can pass through the holes in the perforated plate 533 and place its bottom on the placement platform 532. Therefore, the placement frame 530 can be configured with a variety of perforated plates 533 of different specifications to adapt to sample bottles 540 of different specifications, thereby achieving the limitation of the sample bottle 540 on the horizontal plane. Preferably, the sample bottle 540 placed on the tray mechanism 500 can be transferred to the fixing mechanism 400 under the combined action of the drive mechanism 200 and the capping mechanism 300.

[0040] Preferably, such as Figures 3-7As shown, the drive mechanism 200 may include a first drive unit 210 and a second drive unit 220, wherein the movement directions of the first drive unit 210 and the second drive unit 220 are perpendicular to each other and are on the same horizontal plane. In this invention, the movement direction of the first drive unit 210 is defined as the X direction 211, and the movement direction of the second drive unit 220 is defined as the Y direction 221. Preferably, the first drive unit 210 and the second drive unit 220 may be respectively provided with a first cable drag chain 212 and a second cable drag chain 222 for preventing cable entanglement, wear, pull-out, and scattering.

[0041] Preferably, such as Figure 3 and Figure 8 As shown, the drive mechanism 200 may further include a third drive unit 230, wherein the movement direction of the third drive unit 230 is the Z direction 231, which is perpendicular to both the X direction 211 and the Y direction 221, so that the third drive unit 230 can achieve vertical lifting and lowering. Preferably, the third drive unit 230 of the drive mechanism 200 can be connected to other functional mechanisms (such as the cap screwing mechanism 300), so that the third drive unit 230 can directly drive other functional mechanisms (such as the cap screwing mechanism 300) to achieve movement in the Z direction 231.

[0042] Preferably, such as Figures 3-5As shown, the first drive unit 210 may include a first movable frame 218 arranged along the X direction 211, and a first drive motor 213, a first lead screw nut 214, a first ball screw 215, a first movable slide 216, and a first limit switch 217 mounted on the first movable frame 218. The first movable frame 218 is fixed to the frame 100. The first drive motor 213, which is electrically connected to the first cable drag chain 212, is mounted at one end of the first movable frame 218. Its output shaft is coaxially connected to one end of the first ball screw 215 through a first coupling (not shown in the figure). The first coupling uses an elastic material to compensate for transmission clearance and ensure the synchronicity of power transmission. The first ball screw 215 serves as the main transmission shaft, running through the entire drive mechanism 200. Its other end is fixed to the opposite end of the first movable frame 218 through a first bearing seat, forming a rigid support structure to prevent the first ball screw 215 from bending and deforming under load. The first ball screw 215 has precision threaded raceways machined on its surface, and the screw nut fitted on it contains circulating balls. The screw threaded pair converts the rotational motion of the motor into linear motion. The first screw nut 214 and the first movable slide 216 are fixedly connected by screws or welding to ensure consistent rigidity during movement. The first movable slide 216 is a long strip-shaped metal component with two sets of guide rail sliders symmetrically distributed longitudinally at its bottom. The sliders have dovetail or rectangular cross-sections and form a sliding pair with the guide rail grooves of the first movable frame 218. The guide rail surface is hardened and coated with a low-friction coating to ensure smooth linear movement of the first movable slide 216 in the X direction 211. The top of the first movable slide 216 has several through holes and positioning holes for mounting the second drive unit 220. First limit switches 217 with brackets are fixed at both ends of the first movable frame 218, and the brackets are connected to the frame 100 by screws.

[0043] Preferably, such as Figure 3 and Figure 6 , Figure 7As shown, the second drive unit 220 may include a second movable frame 228 arranged along the Y direction 221, and a second drive motor 223, a second coupling 225, a second movable slide 226, a second limit switch 227, and a second lead screw nut 224 disposed on the second movable frame 228. The output shaft end face of the second drive motor 223, which is electrically connected to the second cable drag chain 222, is provided with a keyway. Power transmission is achieved through the second coupling 225 and the second lead screw nut 224. The second coupling 225 may adopt an elastic sleeve structure nested in the connection part between the motor shaft and the second lead screw nut 224. The body of the second coupling 225 is a split square frame structure, and a radial elastic corrugated washer is provided inside to compensate for axial offset. The second lead screw nut 224 is a cylindrical precision-machined part with double-ended helical threads distributed axially on its outer surface. Its thread raceway forms a rolling contact pair with the ball screw. The second lead screw nut 224 is fixed in the bottom groove of the second movable slide 226 via a flange. The flange edge has four sets of countersunk screw holes for screwing into the second movable slide 226. The second movable slide 226 is a long strip of aluminum alloy profile with two sets of dovetail-shaped guide rail sliders symmetrically arranged at the bottom. The bottom surface of the sliders forms a V-shaped contact surface with the frame guide rail groove. The top of the second movable slide 226 has a grid-like through-hole array for mounting the third drive unit 230. The second limit switch 227 can be mounted on the vertical mounting surface of the end plates on both sides of the frame; its main body is a rectangular plastic shell.

[0044] Preferably, such as Figure 3 and Figure 8 As shown, the third drive unit 230, which is mounted on the second drive unit 220, can be directly connected to the capping mechanism 300. The third drive unit 230 may include a third movable frame 233 arranged along the Z direction 231 and a third drive motor 232 mounted at one end of the third movable frame 233. Further, the third drive unit 230 may also include a third movable slide 234 capable of reciprocating along the Z direction 231 on the third movable frame 233. The third movable slide 234 may be connected to the bottle opening motor 330 of the capping mechanism 300, so that when the third drive motor 232 drives the third movable slide 234 to move, it can simultaneously drive the bottle opening motor 330 to move, thereby moving the bottle opening claw 310 through the capping nut 320. Driven by the drive mechanism 200, the bottle opener 310 can move the gripped sample bottle 540 along one or more of the X direction 211, Y direction 221, and Z direction 231, thereby facilitating the transfer of the sample bottle 540 from the tray mechanism 500 to the fixing mechanism 400, and performing a capping operation on the sample bottle 540 placed on the fixing mechanism 400.

[0045] Optionally, the drive mechanism 200 can also select other suitable drive methods based on the specifications or weight of the sample vial 540, such as pulley drive, conveyor belt drive, etc. The precise positioning and multi-dimensional motion control of the sample vial 540 by the drive mechanism 200 are common knowledge in the field, and many existing technologies (such as CN213689654U) have disclosed corresponding implementation methods. This utility model does not involve any improvement to the positioning and motion control methods of the drive mechanism 200.

[0046] Preferably, such as Figure 1 and Figure 9 As shown, the fixing mechanism 400 can be installed on the operating table, and the installation method can be, for example, bolt fixing. Preferably, the fixing mechanism 400 may include a bottle gripper 410, a bottle body support plate 420, and a finger cylinder 430. The bottle gripper 410 and the bottle body support plate 420 can define the placement space of the sample bottle 540. Under the drive of the finger cylinder 430, the bottle gripper 410 can adjust its opening and closing degree, thereby realizing the placement and removal of the sample bottle 540. Preferably, when the sample bottle 540 is located within the placement space of the fixing mechanism 400, the bottom 543 of the sample bottle 540 can be placed on the bottle body support plate 420. The two jaws 411 of the bottle gripper 410 can clamp the bottle body of the sample bottle 540 from opposite sides. The inner sides of the two jaws 411 of the bottle gripper 410 may be provided with grooves corresponding to the curvature of the bottle body of the sample bottle 540 to ensure clamping of the sample bottle 540. Preferably, the surfaces of the grooves on the inner sides of the two jaws 411 of the bottle gripper 410 are provided with a resistance layer, which has high friction to minimize the rotation of the sample bottle 540 within the placement space.

[0047] Preferably, such as Figure 1 , Figure 3 and Figure 8As shown, the capping mechanism 300 can grip the sample vial 540 (especially the cap 541 of the sample vial 540), so that the capping mechanism 300 can drive the sample vial 540 to perform multi-dimensional movements under the drive mechanism 200, such as transferring it from the tray mechanism 500 to the fixing mechanism 400. Preferably, the capping mechanism 300 may include a bottle opening claw 310, a capping nut 320, and a bottle opening motor 330, wherein the bottle opening claw 310 can be connected to the bottle opening motor 330 through the capping nut 320, so that the power output by the bottle opening motor 330 can be transmitted to the bottle opening claw 310 through the capping nut 320. Preferably, the multiple jaw heads 311 of the bottle opener 310 can define the receiving space for the cap 541 of the sample bottle 540, so that after the cap 541 of the sample bottle 540 enters the receiving space, the cap 541 of the sample bottle 540 can be limited by tightening the bottle opener 310, thereby allowing the sample bottle 540 to move synchronously with the capping mechanism 300. Further, after the capping mechanism 300 transfers the sample bottle 540 from the tray mechanism 500 to the placement space of the fixing mechanism 400, the bottle body support plate 420 of the fixing mechanism 400 can support the bottom 543 of the sample bottle 540, and the bottle gripping jaws 410 of the fixing mechanism 400 can clamp the side wall 542 of the sample bottle 540, so that the bottle opener motor 330 can loosen or tighten the cap 541 by rotating the bottle opener 310. The capping mechanism 300 can be adjusted according to the different sample bottles 540. For example, based on the different positions of gripping the sample bottle 540 (such as the cap 541, the bottle body), there are different force points, which requires setting three, four, five or other different numbers or specifications of claw heads 311.

[0048] According to a preferred embodiment, such as Figure 1 As shown, this utility model also discloses a sampling device, which is equipped with the above-mentioned sample bottle opening device, and further includes a sample injection mechanism 600 disposed on the frame 100, for drawing the liquid to be tested from the sample bottle 540 opened by the bottle cap 541, and then transferring the drawn liquid to the analytical instrument for testing.

[0049] Preferably, the second drive unit 220 may be provided with a plurality of third drive units 230, which can be connected to different functional mechanisms respectively. One third drive unit 230 can be used to connect to the capping mechanism 300, and another third drive unit 230 can be used to connect to the sample injection mechanism 600. For example Figure 1 and Figure 10As shown, the sample injection mechanism 600 connected to the third drive unit 230 can move synchronously with the drive mechanism 200. The sample injection mechanism 600 has a vertically oriented structure and is connected to the third drive unit 230 via a mounting block 610. A connector 620 can be provided on the other side of the mounting block 610. Further, one side of the connector 620 can be connected to a suction device 630 equipped with a sample injection needle 640 and a liquid level detector 650. This allows the sample injection mechanism 600 to penetrate into the sample vial 540 to draw the liquid to be tested as it moves downward with the third drive unit 230, and then move upward with the third drive unit 230 to remove it from the sample vial 540. The removed liquid can be delivered to the analytical instrument via a conduit. The liquid level detector 650 can be a conventional or readily available device; this invention does not involve improvements to the sensing method.

[0050] Preferably, such as Figure 11 and Figure 12 As shown, the sampling device may further include a waste liquid treatment mechanism 800, which may include a discharge section 820 and a cleaning section 810. Both the discharge section 820 and the cleaning section 810 may be equipped with a base 801, which may be circular and can be fixed to the operating platform 900 by bolts or other means. The discharge section 820 may be configured as a vertically placed cylindrical tube 802 with an opening at the top with an annular edge.
