Description

Technical Field

[0001] This disclosure relates to the technical field of particle size detection, such as a lifting and flipping device and a particle size detection device. Background Technology

[0002] Particle detection equipment based on the electrosensitive area method currently widely uses a lifting-type detection stage. The operating principle of this type of equipment is mainly to use a lifting mechanism to fix the sample-containing detection cup within a specific detection area for particle detection. After detection, the detection cup usually needs to be manually removed, cleaned, and any remaining detection liquid disposed of. However, this method is cumbersome and inefficient.

[0003] To overcome the aforementioned problems, related technologies have proposed a design scheme using multiple motors working in tandem. For example, one motor controls the lifting and lowering of the probe, while another motor is responsible for tilting the test cup and handling waste liquid. Although this method simplifies the operation process and reduces manual intervention to some extent, the multi-motor design requires sufficient internal space to install each motor and its supporting components, inevitably increasing the overall size of the equipment and requiring more experimental space. To ensure precise coordination between the probe lifting and lowering and the tilting of the test cup, complex debugging work is necessary, placing higher demands on the control system and extending the equipment setup time. Furthermore, introducing multiple motors not only increases the initial manufacturing cost of the equipment but also increases the difficulty of subsequent maintenance. If a motor or its related components fail, repair and replacement become more complex, affecting the long-term reliability and service life of the equipment.

[0004] It is evident that, among related technologies, particle detection equipment based on the electrical sensing zone method, while employing a multi-motor collaborative design to simplify the operation process, increases the equipment size, complexity, and maintenance difficulty, leading to longer setup time and reduced long-term reliability.

[0021] In some embodiments, the first toothless portion has a first plane that is lower than the tooth tip of the first toothed portion; the second toothless portion has a second plane that is greater than the tooth tip circle radius of the second toothed portion at a distance between the second plane and the center point of the incomplete gear; during the first stroke of the slider, the first plane of the first toothless portion and the second plane of the second toothless portion are parallel and abut against each other.

[0022] In some embodiments, the first toothless portion and the first toothed portion have a first intersecting region in the extension direction of the incomplete rack. The first toothless portion has a groove in the first intersecting region. The bottom surface of the groove and the first plane belong to the same continuous and complete surface.

During the movement, when the incomplete gear meshes with the toothed part of the incomplete rack, the clamp can automatically tilt, thereby automatically tilting the test cup to pour out the solution without manual intervention. Compared to designs using multiple motors, the lifting and tilting device provided in this embodiment only requires one drive component to complete the linear movement of the slider and the tilting action of the clamp. This compact design reduces the need for additional installation space, making the entire device more compact and occupying less experimental space. By using a single drive component and the incomplete gear and rack engagement mechanism, the complex debugging and precise timing requirements of multi-motor collaborative operation are avoided. This not only simplifies the design of the control system and reduces the overall system complexity, but also reduces the risk of failure, facilitates maintenance and replacement, and improves the overall maintainability of the equipment.

[0061] This disclosure provides a lifting and tilting device 100, combined with... Figures 1 to 4 As shown, the lifting and tilting device 100 includes a base 1, a slider 2, a clamp 3, an incomplete rack 4, an incomplete gear 5, and a drive assembly 6.

[0062] The clamp 3 is used to fix the detection cup 7. The clamp 3 is rotatably mounted on the slider 2, and the rotation center of the clamp 3 is parallel to the first direction. The incomplete rack 4 has a first toothless portion 41 and a first toothed portion 42. For ease of understanding and description, the teeth in the first toothed portion 42 are defined as the first tooth 421. The incomplete rack 4 is mounted on the base 1 and is parallel to the second direction, which is perpendicular to the first direction. The incomplete gear 5 has a second toothless portion 51 and a second toothed portion 52. For ease of understanding and description, the teeth in the second toothed portion 52 are defined as the second tooth 521. The first toothless portion 41 is used to cooperate with the second toothless portion 51, and the first toothed portion 42 is used to mesh with the second toothed portion 52. The incomplete gear 5 is rotatably mounted on the slider 2. The incomplete gear 5 and the clamp 3 are fixedly connected, and their rotation centers are coaxial. The drive assembly 6 is mounted on the base 1 and is connected to the slider 2 in a transmission manner. The drive assembly 6 is used to drive the slider 2 to move in the second direction, so that the slider 2 drives the clamp 3 and the incomplete gear 5 to move in the second direction. At a preset position, the engagement of the first toothless part 41 and the second toothless part 51 can be changed to the engagement of the first toothed part 42 and the second toothed part 52, so that the detection cup 7 can be flipped relative to the slider 2.

[0063] In this embodiment of the disclosure, the slider 2 has a first stroke and a second stroke in the second direction, the first stroke being... Figure 1 L1 in the middle, the second leg is Figure 1 L2 in the diagram. The first stroke refers to a specific distance that slider 2 moves along the second direction from its initial position. After moving this specific distance, slider 2 continues to move along the second direction beyond the first stroke and enters the second stroke. The drive component 6 can drive slider 2 to move sequentially through the first and second strokes, or sequentially through the second and first strokes. (Combined with...) Figure 5 As shown, Figure 5The diagram illustrates the positional states of the incomplete rack 4 and incomplete gear 5 as the slider moves through the first and second strokes. State A represents the position of the incomplete rack 4 and incomplete gear 5 when the slider is in the first stroke; states B and C represent the position of the incomplete rack 4 and incomplete gear 5 when the slider transitions from the first stroke to the second stroke; and state D represents the position of the incomplete rack 4 and incomplete gear 5 when the slider is in the second stroke. During the first stroke of slider 2, the first toothless portion 41 and the second toothless portion 51 engage, and slider 2, incomplete gear 5, and clamp 3 all move linearly along the second direction. During the second stroke of slider 2, slider 2, incomplete gear 5, and clamp 3 continue to move linearly along the second direction. Simultaneously, the first toothed portion 42 and the second toothed portion 52 mesh, causing incomplete gear 5 to rotate relative to slider 2. Incomplete gear 5 drives clamp 3 to rotate relative to slider 2, and the rotation of clamp 3 causes the detection cup 7 to flip relative to slider 2.

[0064] Combination Figure 6 As shown, the lifting and flipping device 100 provided in this embodiment can be applied to a particle size detection device. The particle size detection device also includes a particle size detection device 200, which includes an electrode 201 for probing the detection cup 7, a test tube 202, and a stirring paddle 203. In the initial state, the detection cup 7 contains the solution to be tested. The slider 2 is located at the initial position in the first stroke, and the electrode 201, test tube 202, and stirring paddle 203 of the particle size detection device 200 are inserted into the solution in the detection cup 7. At this time, the particle size information of the solution can be detected using the particle size detection device 200. After the detection is completed, the driving component 6 can drive the slider 2 to move sequentially through the first stroke and the second stroke. In the second stroke of the slider 2, the detection cup 7 begins to gradually flip until the solution is poured out.

[0065] The lifting and tilting device 100 provided in this embodiment has a drive component 6 that drives the slider 2 to move the clamp 3 and the incomplete gear 5 synchronously. During the movement, when the incomplete gear 5 meshes with the toothed part of the incomplete rack 4, the clamp 3 can automatically tilt, thereby automatically tilting the test cup 7 to pour out the solution without manual intervention. Compared with designs using multiple motors, the lifting and tilting device 100 provided in this embodiment only requires one drive component 6 to complete the linear movement of the slider 2 and the tilting action of the clamp 3. This compact design reduces the need for additional installation space, making the entire device more compact and occupying less experimental space. By using a single drive component 6 and the engagement mechanism of the incomplete gear 5 and the incomplete rack 4, the complex debugging and precise timing requirements of multiple motors 61 working together are avoided. This not only simplifies the design of the control system and reduces the complexity of the overall system, but also reduces the risk of failure, facilitates maintenance and replacement, and improves the overall maintainability of the equipment.

[0066] In some embodiments, combined with Figure 2 As shown, the lifting and tilting device 100 also includes a limit switch 10, which is used to detect whether the slider 2 is in the initial position of the first stroke.

[0067] In some embodiments, the drive assembly 6 includes a motor 61 and a lead screw 62. The motor 61 is fixed to the base 1, and the lead screw 62 is rotatably disposed on the base 1 and parallel to the second direction. The slider 2 is threadedly engaged with the lead screw 62. The motor 61 and the lead screw 62 are connected in a transmission manner, and the motor 61 drives the lead screw 62 to rotate, and the slider 2 moves along the second direction under the drive of the thread force.

[0068] This embodiment employs a single motor 61 and a lead screw 62 instead of multiple motors working together, simplifying the overall system's mechanical structure. This not only reduces the equipment's size but also lowers design complexity and manufacturing costs. Furthermore, fewer components mean a lower failure rate and higher system reliability. The lead screw 62 efficiently converts the rotational motion of the motor 61 into the linear motion of the slider 2. This motion conversion method is highly efficient and responsive, enabling the slider 2 to complete its displacement task quickly and smoothly, thus improving overall work efficiency.

[0069] In some embodiments, the drive assembly 6 may include a cylinder (not shown), the piston rod of which is connected to the slider 2. The cylinder drives the piston rod to extend and retract, thereby moving the slider 2 in a second direction.

[0070] In some embodiments, combined with Figure 1 and Figure 2As shown, the base 1 includes a vertical plate 11, a bearing plate 12, and two supports 13, which are spaced apart along a first direction. A motor 61 is fixed to the top surface of the vertical plate 11; for example, the end face of the motor 61 can be bolted to the top surface of the vertical plate 11. The output shaft of the motor 61 passes through the vertical plate 11 and is coaxially connected to one end of a lead screw 62; for example, the output shaft of the motor 61 can be coaxially connected to one end of the lead screw 62 via a coupling 63. Both ends of the lead screw 62 are rotatably mounted on corresponding supports 13. When the output shaft of the motor 61 rotates, it drives the lead screw 62 to rotate.

[0071] In this embodiment, the upright plate 11, the bearing plate 12, and the two supports 13 of the base 1 are spaced apart along a second direction, forming a stable foundation frame. This structure enhances the rigidity and stability of the entire device, ensuring that there will be no shaking or displacement during operation, thereby guaranteeing the accuracy and reliability of the detection process. The motor 61 and the lead screw 62 are respectively mounted on the upright plate 11 and the supports 13, providing stable support points for the motor 61 and the lead screw 62, ensuring that the motor 61 and the lead screw 62 remain stable during operation, avoiding uneven wear caused by friction or eccentricity, and extending their service life.

[0072] In some embodiments, combined with Figure 2 As shown, the incomplete rack 4 is fixed to the vertical plate 11. For example, the incomplete rack 4 can be fixed to the top surface of the vertical plate 11 by bolts. The height direction of the first tooth 421 in the first toothed portion 42 of the incomplete rack 4 is parallel to the top surface of the vertical plate 11; the thickness direction of the first tooth 421 in the first toothed portion 42 of the incomplete rack 4 is perpendicular to the top surface of the vertical plate 11.

[0073] In some embodiments, combined with Figure 2 As shown, the drive assembly 6 also includes a guide portion 64. The guide portion 64 is fixedly disposed on the base 1 and parallel to the second direction, and the slider 2 is slidably engaged with the lead screw 62. The guide portion 64 can limit the movement direction of the base 1, ensuring that the slider 2 can move accurately along the second direction. Optionally, the guide portion 64 can be a guide rod, a guide groove opened on the top surface of the upright plate 11, or a guide rail laid on the top surface of the upright plate 11. Taking the guide portion 64 as a guide rod as an example, both ends of the guide portion 64 are rotatably disposed on the corresponding supports 13. The number of guide portions 64 can be determined according to actual design needs. For example, the drive assembly 6 includes two guide portions 64. It is understood that when the guide portion 64 is a guide groove provided on the top surface of the upright plate 11, at least a part of the slider 2 is embedded in the guide groove. When the guide portion 64 is a guide rail laid on the top surface of the upright plate 11, the slider 2 has a guide groove, and the guide rail is embedded in the guide groove.

[0074] In some embodiments, combined with Figure 1 and Figure 7 As shown, the lifting and flipping device 100 also includes a rotating shaft 8, which is rotatably mounted on the slider 2. The clamp 3 and the incomplete gear 5 are both fixedly connected to the rotating shaft 8. During the second stroke of the slider 2, the first toothed portion 42 and the second toothed portion 52 mesh with each other, and the incomplete gear 5 rotates relative to the slider 2. The incomplete gear 5 drives the clamp 3 to rotate relative to the slider 2 through the rotating shaft 8. The rotation of the clamp 3 can flip the detection cup 7 relative to the slider 2.

[0075] In some embodiments, the clamp 3 and the incomplete gear 5 are spaced apart along a first direction and distributed on both sides of the slider 2. Figures 8 to 10 As shown, the clamp 3 is provided with a first locking groove 31, the incomplete gear 5 is provided with a second locking groove 53, and the two ends of the rotating shaft 8 are respectively provided with a first locking block 81 and a second locking block 82. The first locking block 81 is provided in the first locking groove 31, and the second locking block 82 is provided in the second locking groove 53.

[0076] In some embodiments, the clamp 3 is C-shaped, with a first snap-fit ​​groove 31 located in the middle of the clamp 3, and both ends of the clamp 3 used to hold the detection cup 7.

[0077] In this embodiment, since both the clamp 3 and the incomplete gear 5 are fixed on the same rotating shaft 8, the rotation of the incomplete gear 5 directly drives the clamp 3 to rotate synchronously. This ensures that the detection cup 7 can be precisely flipped at a predetermined angle, thereby achieving the function of automatically pouring the solution. Using a single rotating shaft 8 to simultaneously drive the rotation of the clamp 3 and the incomplete gear 5 simplifies the mechanical structure. This not only reduces the size of the equipment but also lowers manufacturing costs and maintenance difficulty, and improves the reliability and durability of the system.

[0078] In some embodiments, the first locking groove 31 includes a first irregular countersunk hole 311 and a first circular hole 312 that communicate with each other, and the maximum inner diameter of the first irregular countersunk hole 311 is larger than the diameter of the first circular hole 312. The first locking block 81 is adapted to the shape of the first irregular countersunk hole 311, and the rotating shaft 8 passes through the first irregular countersunk hole 311 and the first circular hole 312. The first locking block 81 is disposed in the first irregular countersunk hole 311, and the maximum outer diameter of the first locking block 81 is larger than the outer diameter of the cylindrical portion of the rotating shaft 8.

[0079] In this embodiment, the first irregular countersunk hole 311 and the first locking block 81 have the same shape. Their shapes can be determined according to actual design needs. For example, the first irregular countersunk hole 311 can be a hexagonal countersunk hole, and the first locking block 81 is a hexagonal column.

[0080] In some embodiments, the rotating shaft 8 includes a rotating shaft body 83 and a second locking block 82. One end face of the rotating shaft body 83 is provided with a countersunk groove 831. The second locking block 82 includes a shaped portion 821 and a cylindrical portion 822 connected to each other. The shaped portion 821 is adapted to the shape of the countersunk groove 831. The second locking groove 53 includes a second shaped countersunk hole 531 and a second circular hole 532 that are connected. The maximum inner diameter of the second shaped countersunk hole 531 is smaller than the diameter of the first circular hole 312. The shaped portion 821 is adapted to the shape of the second shaped countersunk hole 531. The shaped portion 821 passes sequentially through the second circular hole 532 and the second shaped countersunk hole 531 and is then positioned in the countersunk groove 831. The cylindrical portion 822 is positioned in the first circular hole 312. Here, the rotating shaft body 83 is rotatably mounted on the slider 2. The first locking block 81 is located at the end of the rotating shaft body 83 away from the second locking block 82. The first locking block 81 is fixedly connected to the rotating shaft body 83, and the maximum outer diameter of the first locking block 81 is larger than the outer diameter of the rotating shaft body 83. Optionally, the second locking block 82 can be bolted to the rotating shaft body 83.

[0081] In this embodiment of the disclosure, the shapes of the irregular countersunk groove 831, the irregular part 821, and the second irregular countersunk hole 531 are consistent. The shapes of the three can be determined according to actual design needs. For example, the irregular countersunk groove 831 can be a hexagonal countersunk groove, the irregular part 821 can be a hexagonal column, and the second irregular countersunk hole 531 can be a hexagonal countersunk hole.

[0082] The plane 411 is lower than the tooth tip of the first toothed portion 42. The second toothless portion 51 has a second plane 511. The distance between the second plane 511 and the center point of the incomplete gear 5 is greater than the radius of the tooth tip circle of the second toothed portion 52. During the first stroke of the slider 2, the first plane 411 of the first toothless portion 41 and the second plane 511 of the second toothless portion 51 are parallel and abut against each other.

[0083] During the first stroke of slider 2, the first plane 411 of the first toothless portion 41 and the second plane 511 of the second toothless portion 51 are parallel and abut against each other. This ensures that slider 2 can move smoothly without jamming or vibration when the toothless portions interact, providing a more stable operating experience. The distance between the second plane 511 of the second toothless portion 51 and the center point of the incomplete gear 5 is greater than the tooth tip circle radius of the second toothed portion 52. This design ensures that there is no interference during the transition from the toothless portion to the toothed portion. Specifically, when slider 2 enters the second stroke from the first stroke, the tooth tips can smoothly begin to mesh without collision or jamming due to insufficient distance. By designing the precise fit between the first plane 411 and the second plane 511, unnecessary friction and impact are reduced, thereby reducing the wear rate of mechanical parts and reducing noise during operation.

[0084] In this embodiment of the present disclosure, the first toothless portion 41 and the first toothed portion 42 have a first intersecting region M in the extension direction of the incomplete rack 4. The first toothless portion 41 has a groove 412 in the first intersecting region M. The bottom surface of the groove 412 is on the same continuous and complete surface as the first plane 411. The width of the first tooth 421 of the first toothed portion 42 in the first intersecting region M is smaller than the width of the other first teeth 421.

[0085] The second toothless portion 51 and the second toothed portion 52 have a second interlacing region N in the circumferential direction of the incomplete gear 5. The width of the second plane 511 in the second interlacing region N is smaller than the width of the second plane 511 of other portions. The width of the second tooth 521 of the second toothed portion 52 in the second interlacing region N is smaller than the width of the second tooth 521 of other portions.

[0086] During the transition between the first and second strokes of the slider 2, the first tooth 421 of the first interlacing region M engages with the second tooth 521 of the second interlacing region N, and the groove 412 of the first interlacing region M accommodates the end of the second toothless portion 51 in the second interlacing region N.

[0087] A groove 412 is provided in the extending direction of the first toothless portion 41, and the bottom surface of the groove 412 is continuous with the first plane 411. When the slider 2 moves from the first stroke to the second stroke, the second toothless portion 51 can be smoothly embedded in the groove 412, leaving clearance space for the end of the second toothless portion 51 to avoid direct collision. The first tooth 421 of the first interlacing region M and the second tooth 521 of the second interlacing region N both adopt a narrower width design to ensure that the contact area of ​​the tooth side gradually increases at the beginning of engagement, rather than instantaneous full-width contact. The above design can achieve a smooth transition from toothless to toothed engagement, reduce mechanical impact and vibration, and avoid jamming or noise caused by sudden engagement.

[0088] In some embodiments, combined with Figure 11 As shown, the lifting and tilting device 100 also includes a protective housing 9. The base 1, slider 2, clamp 3, incomplete gear 5, incomplete rack 4, drive assembly 6, guide 64, and rotating shaft 8 are all located inside the protective housing 9, while the clamp 3 and detection cup 7 are located outside the protective housing 9. The protective housing 9 has a clearance groove extending in a second direction, and the connection between the protective housing 9 and the clamp 3 passes through the clearance groove.

[0089] In some embodiments, the lifting and tilting device further includes a control module (not shown in the figure). The control module can control the drive component to drive the slider to move sequentially through a first stroke and a second stroke, or sequentially through a second stroke and a first stroke. The control module includes a processor and a memory. Optionally, the control module may also include a communication interface and a bus. The processor, communication interface, and memory can communicate with each other via the bus. The communication interface can be used for information transmission. The processor can call logical instructions in the memory to control the drive component to drive the slider to move sequentially through a first stroke and a second stroke, or sequentially through a second stroke and a first stroke.

[0090] Furthermore, the logical instructions in the aforementioned memory can be implemented as software functional units and sold or used as independent products, and can be stored in a computer-readable storage medium. As a computer-readable storage medium, the memory can be used to store software programs and computer-executable programs, such as the program instructions / modules corresponding to the methods in this embodiment. The processor executes functional applications and data processing by running the program instructions / modules stored in the memory, that is, controlling the drive component to drive the slider to move sequentially through the first stroke and the second stroke, or sequentially through the second stroke and the first stroke.

[0091] The memory may include a program storage area and a data storage area. The program storage area may store the operating system and applications required for at least one function; the data storage area may store data created based on the use of the terminal device. Furthermore, the memory may include high-speed random access memory and may also include non-volatile memory.

[0092] The device embodiments described above are merely illustrative. For example, the division of units may only be a logical functional division, and in actual implementation, there may be other division methods. For instance, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the shown or discussed mutual couplings, direct couplings, or communication connections may be through some interfaces, indirect couplings, or communication connections between devices or units, and may be electrical, mechanical, or other forms. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units, i.e., they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to implement this embodiment according to actual needs. Additionally, the functional units in the embodiments of this disclosure may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit.
