Description

Technical Field

[0001] This invention relates to the field of pen refill manufacturing technology, specifically to a detection device and method based on a regulator. Background Technology

[0002] The ink refill regulator is a core component for precisely controlling the ink output of writing instruments. Its function and structure vary depending on the type of pen. For example, patent CN116215115B provides a bouncing ball refill that facilitates ink output. When writing, the outer ball is compressed, pushing the inner ball inward, causing the ink core to move away from the pen tip. When writing stops, the first compression spring causes the ink core to move closer to the pen tip, resulting in a back-and-forth movement of the ink core. This causes the scraper to push ink towards the pen tip when it moves towards the pen tip, and to slide ink out from the inclined surface when it moves away from the pen tip, thus ensuring that the ink moves towards the pen tip rather than away from it, thereby facilitating ink output. The ink core is inserted inside the regulator, which is encapsulated inside the pen tube. The regulator maintains the stability of the ink core during ink output control, therefore, the manufacturing dimensions (such as outer diameter and inner diameter) and installation accuracy of the regulator are subject to high requirements. The figure shows the structure of the regulator of this application.

[0003] In related technologies, to facilitate the surface flatness detection of smaller pencil leads, for example, patent CN115183662B provides a surface flatness detection device for eyebrow pencil leads. This device is equipped with a high-precision induction balance ball and an opposite high-precision induction balance steel ball. Based on the force characteristics of the arc surface model, when the forces at both ends of the connecting line of the lightweight rigid balance ball are equal, the forces along the direction of the rod are the same; conversely, when the arc surface where the high-precision induction balance ball and the opposite high-precision induction balance steel ball are located is flat, they are in a balanced state. When the arc surface is uneven and has bumps, the small ball will move along the track of the scale needle or in the direction the pointer points. At this time, the flatness problem of the lead can be transformed into a scale change problem by observing the scale change with the naked eye.

[0004] While the existing technical solutions described above can achieve the effect of reflecting the surface flatness of the pen refill by setting a balance ball structure on the outside of the pen refill, the pen refill needs to be placed in the clamping airbag of the clamping mechanism during the test. Then, the air pump is activated to make the clamping airbag hold the pen refill. Finally, the pen refill is rotated by driving the clamping airbag. Surface inspection can only be achieved by combining the balance ball detection structure with this process. The repeated installation and removal of the pen refill and the clamping airbag is quite troublesome. In addition, the concentricity of the pen refill and the circumference of the two balance balls must be ensured during installation. Otherwise, the test results will be inaccurate, resulting in the drawback of cumbersome loading and unloading operations during pen refill inspection. Summary of the Invention

[0009] Furthermore, the ring array of limiting rods consists of four rods, and the angle between the axis of the limiting rod and the moving direction of the regulator body is 45°, which is used to automatically allow the regulator body to move out of its way.

The detection end of the detection sensor is fixedly connected to the mandrel. An outer sleeve is disposed at the bottom of the mounting plate and fitted over the outer side of the inner sleeve; In the detection state, the inner sleeve is located inside the insert hole of the regulator body and is used to detect the inner diameter of the regulator body, while the outer sleeve is located outside the regulator body and is used to detect the outer diameter of the regulator body.

[0013] Furthermore, an arc-shaped fixing plate is fixedly provided on the inner side of the outer sleeve, and the arc-shaped fixing plate is fixedly connected to the outer sleeve through a fixing ring at the bottom; An arc-shaped sliding plate is slidably disposed on the inner side of the outer sleeve, and the arc-shaped sliding plate is slidably disposed between the outer sleeve and the arc-shaped fixed plate; The inner side of the arc-shaped sliding plate is also fixedly provided with a detection protrusion, which is used to detect the outer diameter of the fins on the outer side of the regulator body; Springs C are symmetrically fixed on both sides of the detection protrusion, and the other ends of the springs C are located on the vertical sides of the arc-shaped fixing plate. Sensors are installed on both vertical sides of the arc-shaped fixing plate corresponding to spring C to detect the pressure of spring C.

[0014] Furthermore, the carrier component includes: The bottom frame is fixedly connected to the connectors via connecting plates on both sides. Vertical plates are fixedly installed on both sides of the top of the bottom frame, and a support plate is provided between the two vertical plates; The top of the support plate has a socket, and several sockets are evenly arranged for inserting the insertion end of the regulator body and for supporting the outer ring outside the insertion end.

[0015] Furthermore, each of the vertical plates has a vertical rod slidably mounted on its top, the bottom end of the vertical rod is fixedly connected to the bearing plate, and a limit block is fixedly mounted on the top end of each vertical rod. A spring A is mounted on the outside of the vertical rod between the vertical plate and the limit block.

Connectors are uniformly fixed on the outside of chain A for connecting and installing the load-bearing assembly. A feeding platform is provided on the side of the base near the downward-moving support component.

[0017] According to another aspect of the embodiments of this application, a detection method based on a regulator-based detection device is proposed, comprising the following steps: S1. Before the conveying component and the carrying component reach the bottom of the detection component, the outer ring at the bottom of the regulator body is inserted into the insertion hole on the inner side of the carrying plate by a robotic arm or manually. The inner diameter of the insertion hole is larger than the outer diameter of the outer ring and smaller than the outer diameter of the outer ring, thereby supporting several regulator bodies through the carrying plate. S2. The carrier component carrying the regulator body is driven to move intermittently by the conveying component, so that the carrier component drives the regulator body to move below the detection component to wait for detection; S3. Position the regulator body carried by the support plate using the positioning components inside the frame, so that the regulator body is coaxially aligned with the detection components above, laying the foundation for subsequent detection work. S4. The detection component is driven to descend vertically, so that the detection component positions the regulator body after positioning the positioning component. During the detection, the inner sleeve inside the regulator body and the outer sleeve outside the regulator body are used to detect the inner diameter and outer diameter of the regulator body respectively. During the detection process, a robotic arm or manual labor can be used to remove unqualified regulator bodies. S5. The conveying component continues to drive the carrier component to move forward. When the carrier component moves to one end of the conveying component, it begins to move downward, so that the regulator body carried by the carrier component is automatically unloaded by its own gravity. After unloading, the carrier component continues to move to the top to support the regulator body under the drive of the conveying component, realizing continuous feeding detection and automatic unloading.

[0018] Beneficial effects 1. The technical solution provided by this invention has the following beneficial effects compared with the prior art: This invention achieves precise detection of the regulator body by incorporating a support component, a detection component, and a positioning component. Simultaneously, the support component carries the regulator body and transports it to the bottom of the detection component via a conveyor component. The positioning component directly below the detection component positions the regulator body, ensuring coaxial positioning between the regulator body and the detection component. This effectively reduces manual intervention and improves detection efficiency and accuracy. The combination of continuous feeding and automatic unloading not only shortens the operation cycle but also significantly enhances the automation level of the production line, meeting the demands of modern industry for high-efficiency, high-quality production.

[0019] 2. This invention, through the precise coordination of its components, accurately detects the inner and outer diameters of the regulator body and the outer diameter of the fins, while also reducing damage to the regulator body during the inspection process. This not only improves subsequent installation efficiency but also effectively avoids installation errors caused by dimensional inconsistencies. Attached Figure Description

[0023] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0024] The present invention will be further described below with reference to embodiments. For example... Figure 10 The diagram shows the specific structure of the regulator.

[0025] Please see Figures 1-10This invention provides a technical solution: a regulator-based testing device, comprising a frame 1, a conveying component 2, a bearing component 3, a positioning component 4, and a testing component 5. A testing component mounting frame 11 is fixedly mounted on the top of the frame 1. The conveying component 2 is disposed inside the frame 1 and is used to convey the regulator body 100. The bearing components 3 are evenly disposed inside the frame 1 and are used to support the regulator body 100, and move synchronously under the drive of the conveying component 2. The positioning component 4 is disposed inside the frame 1 and located below one of the bearing components 3, and is used to position the regulator body 100 supported by the bearing component 3. The testing component 5 is disposed inside the testing component mounting frame 11 and is driven to move up and down by external force, used to test the regulator body 100 after it has been positioned by the positioning component 4.

[0026] When inspecting the regulator body 100, the regulator body 100 is placed at the bottom of the support component 3 by a robotic arm or manually. The support component 3 supports the regulator body 100. Then, the conveying component 2 drives the support component 3 to move forward, so that the support component 3 moves the regulator body 100 downwards towards the inspection component 5 in preparation for inspection. Before inspection, the positioning component 4 inside the frame 1 positions the regulator body 100 supported by the support component 3, so that the regulator body 100 is coaxially aligned with the inspection component 5 above. Finally, the electric push rod 18 at the top of the inspection component mounting frame 11 drives the inspection component 5 to move downwards, so that the inspection component 5 moves vertically downwards under the limiting action of the slide rod 19. The regulator body 100 is inspected by lifting and moving. After inspection, the conveying component 2 continues to drive the support component 3 to move downwards to transfer the regulator body 100. This achieves the effect of automatic positioning and unloading of the regulator body 100, making the operation more convenient and efficient.

[0027] Based on the above scheme, in this embodiment of the application, the frame 1 is symmetrically fixedly provided with side plates 14, and the bottom plate 15 is fixedly provided at the bottom of the side plates 14; the conveying assembly 2 includes a drive sprocket group 21 and a driven sprocket group 22 rotatably disposed on the outside of the side plates 14, and a motor A25 for driving the drive sprocket group 21 is fixedly provided on the top of the bottom plate 15. The drive sprocket group 21 drives the driven sprocket group 22 to rotate synchronously through the chain A23. Connecting members 24 are uniformly fixedly provided on the outside of the chain A23 for connecting and installing the bearing assembly 3; a base 12 is fixedly provided at the bottom of the frame 1, and a feeding platform 13 is provided on the side of the base 12 that is close to the downward movement of the bearing assembly 3.

[0028] The motor A25 drives the drive sprocket assembly 21 to rotate, which in turn drives the outer connecting piece 24 to move intermittently via the chain A23. This, in turn, drives the bearing assembly 3 to move at equal distances via a set of connecting pieces 24 on the outer sides of the two chains A23, thereby ensuring the accuracy of the bearing assembly 3 in feeding the regulator body 100.

[0029] Based on the above solution, the supporting component 3 of this application embodiment includes a bottom frame 31. The bottom frame 31 is fixedly connected to the connector 24 through the connecting plates 38 on both sides. Vertical plates 32 are fixedly provided on both sides of the top of the bottom frame 31. A supporting plate 34 is provided between the vertical plates 32 on both sides. The top of the supporting plate 34 is provided with an insertion hole 35. Several insertion holes 35 are evenly provided for inserting the insertion end 101 of the regulator body 100 and supporting the outer ring 102 outside the insertion end 101.

[0030] In actual operation, in order to facilitate the insertion of the insertion end 101 of one end of the regulator body 100 into the interior of the socket 35, the inner diameter of the socket 35 will be slightly larger than the outer diameter of the insertion end 101 and smaller than the outer diameter of the outer ring 102. This makes it easier for the robotic arm or manual to install the regulator body 100 on the top of the support plate 34 by insertion, which not only improves the installation efficiency, but also effectively avoids installation errors caused by size mismatch.

[0031] Based on the above solution, the positioning component 4 of this application embodiment includes a fixing plate 41 fixedly disposed between the side plates 14. A vertical shaft 42 is provided on the inner side of the fixing plate 41 corresponding to the insertion hole 35. Limiting rods 43 are arranged in a ring array on the outer side of the vertical shaft 42. The limiting rods 43 are arranged radially along the vertical shaft 42. A slider 44 is slidably disposed on the outer side of each limiting rod 43. A clamping block 45 is fixedly disposed on the top of each slider 44. The clamping block 45 is driven by an external force to slide synchronously along the limiting rod 43, which is used to trigger and release the clamping and positioning action on the insertion end 101.

[0032] In specific implementation, after the carrier plate 34 drives the regulator body 100 to be located below the detection component 5, the slider 44 on the outer side of each vertical shaft 42 is driven to slide radially, so that the slider 44 drives the clamping block 45 to clamp concentrically. The clamping block 45, which is concentrically clamped, drives the regulator body 100 to be coaxially aligned with the detection component 5 in the vertical direction, laying the foundation for the subsequent downward movement of the detection component 5 for detection, and eliminating the detection error caused by the difference in diameter between the socket 35 and the outer ring 102.

[0033] Based on the above scheme, in order to simultaneously position several regulator bodies 100, a turntable 46 is rotatably provided on the outer side of the vertical shaft 42 in this embodiment of the application. An arc-shaped hole 47 is opened on the inner side of the turntable 46. The arc-shaped hole 47 is arranged in a circular array corresponding to the slider 44. A sliding column 48 is slidably provided on the inner side of each arc-shaped hole 47. The sliding column 48 is fixedly provided between the slider 44 and the clamping block 45. The turntable 46 is driven by an external force to rotate synchronously. In a preferred embodiment, four limit rods 43 are arranged in a circular array, and the angle between the axis of the limit rods 43 and the moving direction of the regulator body 100 is 45°, which is used to automatically allow the regulator body 100 to move.

[0034] Specifically, a toothed ring A49 is fixedly installed on the outer side of each turntable 46. Two adjacent toothed rings A49 are meshed with each other, and the arc-shaped holes 47 on the inner side of two adjacent turntables 46 have opposite curvature directions. A toothed ring B411 is fixedly installed on the outer side of one of the turntables 46, and a gear 412 is meshed on the outer side of the toothed ring B411. A motor B413 for driving the gear 412 is fixedly installed at the bottom of the fixing plate 41. A bearing hole 410 is opened on the inner side of each turntable 46 for mounting on the outer side of the vertical shaft 42.

[0035] In practice, the starting motor B413 drives the gear 412 to rotate, and the rotation of the gear 412 further drives the gear ring B411 to rotate, thereby causing the turntable 46 connected to it to rotate synchronously. As the turntable 46 rotates, the arc-shaped hole 47 on its inner side drives the sliding column 48 to move along the drive trajectory, thereby pushing the slider 44 to slide along the limit rod 43. Since the sliding column 48 is fixedly connected between the slider 44 and the clamping block 45, this action ensures that the clamping block 45 can accurately complete the concentric clamping or releasing operation. Furthermore, when one of the turntables 46 rotates, it drives the outer gear ring A49 to rotate, so that the gear ring A49 drives the other gear rings A49 to rotate synchronously through the bearing hole 410, so that the other turntables 46 rotate synchronously.

[0036] Through this linkage design, multiple regulator bodies 100 can be positioned simultaneously, significantly improving detection efficiency and ensuring the positional consistency of each regulator body 100 during the detection process. The structure is compact and stable, adaptable to regulator bodies 100 of different sizes and specifications, and provides reliable support for batch detection.

[0037] Based on the above solution, in this embodiment of the application, an angle sensor 414 is fixedly installed at the top of the vertical shaft 42. The detection end of the angle sensor 414 is coaxially fixed with the turntable 46. The vertical shaft 42 is rotatably installed inside the fixed plate 41. A counterweight block 415 is fixedly installed at the bottom of the vertical shaft 42. The detection component 5 includes an inner sleeve 53 and an outer sleeve 58. Both the inner sleeve 53 and the outer sleeve 58 are located at the bottom of the mounting plate 52, and several are correspondingly provided for the regulator body 100. The inner sleeve 53 is located inside the insert hole 104 and is used to detect the inner diameter of the regulator body 100. The outer sleeve 58 is located outside the regulator body 100 and is used to detect the outer diameter of the regulator body 100.

[0038] Specifically, when the turntable 46 rotates and drives the clamping block 45 to concentrically clamp the regulator body 100, the vertical shaft 42 cannot rotate due to the bottom counterweight 415. The rotation angle of the turntable 46 can be detected by the angle sensor 414 at the top of the vertical shaft 42. After the turntable 46 drives the clamping block 45 to clamp on the outside of the outer ring 102, as the motor B413 continues to drive the turntable 46 to rotate, the vertical shaft 42 drives the bottom counterweight 415 to rotate together. The change in the detection value of the angle sensor 414 can reflect the clamping status of the clamping block 45 on the insertion end 101, preventing overpressure on the insertion end 101. After clamping, it drives the regulator body 100 to rotate continuously, which can be used for subsequent testing work.

[0039] Based on the above solution, the detection component 5 of this application embodiment further includes a plate frame 51. The plate frame 51 is driven to rise and fall within the detection component mounting bracket 11 by external force. A mounting plate 52 is fixedly installed at the bottom of the plate frame 51. A plurality of inner sleeves 53 are fixedly installed on the inner side of the mounting plate 52 corresponding to the vertical axis 42. A spindle 54 is slidably installed on the inner side of the inner sleeve 53. A detection head 55 is fixedly installed at the bottom of the spindle 54 for detecting the inner diameter of the regulator body 100. The end of the regulator body 100 away from the insert hole 104 A core hole 105 is provided, the inner diameter of which is smaller than the inner diameter of the regulator body 100, for installing the compression spring on the outside of the water core. A spring B56 is provided on the outside of the spindle 54 between the inner sleeve 53 and the detection head 55. A detection sensor 57 is fixedly provided on the top of the spindle 54. A data line A571 is fixedly provided on the outside of the detection sensor 57 for transmitting detection information. The detection sensor 57 is fixedly provided on the bottom side of the plate frame 51, and the detection end of the detection sensor 57 is fixedly connected to the spindle 54.

[0040] Based on the above scheme, when the electric push rod 18 drives the plate frame 51 to move downward, the inner sleeve 53 at the bottom of the mounting plate 52 will be inserted through the insert hole 104 at the top of the adjuster body 100 (wherein, the insert hole 104 is used to seal the connection with the pen tube through the connector, for details please refer to the patent document with publication number CN116215115B).

[0041] During the insertion process, the inner diameter of the regulator body 100 is detected by the detection head 55 at the bottom of the mandrel 54 (to ensure that the subsequent water core can be assembled inside the regulator body 100), and the outer diameter of the detection head 55 meets the diameter required for the assembly of the water core. When the inner diameter is being tested, if the inner diameter of the regulator body 100 is small, the downward movement of the testing head 55 will be hindered. At this time, the testing head 55 pushes the spindle 54 upward, so that the spindle 54 exerts pressure on the testing sensor 57 on the bottom side of the plate frame 51. The pressure received by the testing sensor 57 is collected to reflect whether the inner diameter of the regulator body 100 is qualified (if the testing sensor 57 is a displacement sensor, it can be judged by detecting the displacement of the spindle 54). At this time, the plate frame 51 moves upward, causing the inner sleeve 53 to disengage from the inside of the regulator body 100. Then, the unqualified regulator body 100 is removed by a robotic arm or manually, and then the test is carried out again. During the testing process, the rear regulator body 100 continues to feed material onto the top of the support plate 34 via a robotic arm or manually. This allows for simultaneous feeding, ensuring testing efficiency. After testing, the detection head 55 is reset to the detection origin relative to the inner sleeve 53 by the action of the spring B56, ensuring continuous testing.

[0042] Based on the above solution, in this embodiment of the application, an arc-shaped fixing plate 59 is fixedly provided on the inner side of the outer sleeve 58. The arc-shaped fixing plate 59 is fixedly connected to the outer sleeve 58 through the fixing ring 510 at the bottom. An arc-shaped sliding plate 511 is slidably provided on the inner side of the outer sleeve 58. The arc-shaped sliding plate 511 is slidably provided between the outer sleeve 58 and the arc-shaped fixing plate 59. A detection protrusion 512 is fixedly provided on the inner side of the arc-shaped sliding plate 511 for detecting the outer diameter of the fins 103 on the outer side of the regulator body 100. Specifically, springs C513 are symmetrically fixed on both sides of the detection protrusion 512. The other ends of the springs C513 are located on the vertical sides of the arc-shaped fixing plate 59. Sensors are provided on both vertical sides of the arc-shaped fixing plate 59 corresponding to the springs C513 to detect the pressure of the springs C513. A data line B591 for transmitting detection information is fixed on the outside of the arc-shaped fixing plate 59. The data line B591 is electrically connected to the sensors on both sides of the arc-shaped fixing plate 59.

[0043] Based on the above scheme, in this embodiment of the application, when the inner sleeve 53 is inserted into the regulator body 100 by the plate frame 51, the mounting plate 52 simultaneously moves the outer sleeve 58 to the outside of the regulator body 100. When the outer sleeve 58 moves downward and fits onto the outside of the regulator body 100, the outer diameter of the regulator body 100 is detected by the detection protrusion 512 on the inner side of the arc-shaped sliding plate 511. Several fins 103 are provided on the outer side of the regulator body 100, and an annular groove is formed between two adjacent fins 103 (see patent document CN116215115B for details). The outer diameter of the fins 103 is related to the accuracy of the regulator body 100 after being assembled into the pen tube. If the outer diameter of the fins 103 is too large, during the downward movement of the detection protrusion 512... The fin 103 continues to move downwards, and the subsequent start spring C513 continues to drive the turntable 46 to rotate. The turntable 46 drives the regulator body 100 held by the clamping block 45 to rotate. The fin 103 will drive the detection protrusion 512 to rotate to one side, so that the detection protrusion 512 compresses the spring C513 on one side. The spring C513 is arc-shaped and set inside the arc-shaped slide plate 511. The pressure of the spring C513 is collected by the sensor on the outside of the arc-shaped fixing plate 59, which can reflect whether the outer diameter of the fin 103 is qualified. If the outer diameter of the fin 103 is qualified during the downward movement of the detection protrusion 512, the detection protrusion 512 can be used to detect other positions of the fin 103 during the subsequent rotation of the regulator body 100 to ensure that the outer periphery of the fin 103 meets the production requirements.

[0044] Based on the above solution, in this embodiment of the application, the top of the vertical plate 32 is slidably provided with a vertical rod 33, the bottom end of the vertical rod 33 is fixedly connected to the bearing plate 34, the top of the vertical rod 33 is fixedly provided with a limit block 36, and a spring A37 is provided on the outside of the vertical rod 33 between the vertical plate 32 and the limit block 36. The bearing plate 34 moves downward and disengages from the bottom of the outer ring 102 under the pressure of the outer sleeve 58.

[0045] When the outer sleeve 58 moves to the outside of the regulator body 100 to start detection, the outer sleeve 58 will press down on the support plate 34 and move it downward, so that the support plate 34 is away from the bottom of the outer ring 102. At this time, the support plate 34 drives the limit block 36 at the top of the vertical rod 33 to compress the spring A37, which can prevent the regulator body 100 from contacting the support plate 34 and causing wear or jamming when it rotates under the drive of the turntable 46.

[0046] The principle and advantages of regulator-based detection equipment: Includes the following steps: S1. Feeding: Before the conveying component 2 drives the bearing component 3 to reach the bottom of the detection component 5, the outer ring 102 at the bottom of the regulator body 100 is inserted into the insertion hole 35 on the inner side of the bearing plate 34 by means of a robotic arm or manual labor. The inner diameter of the insertion hole 35 is larger than the outer diameter of the outer ring 102 and smaller than the outer diameter of the outer ring 102, thereby supporting several regulator bodies 100 through the bearing plate 34. S2. Conveying: The conveying component 2 drives the bearing component 3, which carries the regulator body 100, to move intermittently, so that the bearing component 3 drives the regulator body 100 to move below the detection component 5 to wait for detection; specifically, the motor A25 drives the drive sprocket group 21 to rotate, so that the drive sprocket group 21 drives the outer connecting piece 24 to move intermittently through the chain A23, and then drives the bearing component 3 to move at equal distances through a set of connecting pieces 24 on the outer side of the two chains A23, so as to ensure the accuracy of the bearing component 3 driving the regulator body 100 to feed materials; S3. Positioning: The positioning component 4 inside the frame 1 positions the regulator body 100 supported by the support plate 34, so that the regulator body 100 is coaxially aligned with the detection component 5 above, laying the foundation for subsequent detection work. S4. Inspection: The detection component 5 is driven to descend vertically, positioning the regulator body 100 after positioning the positioning component 4. During inspection, the inner and outer diameters of the regulator body 100 are inspected by the inner sleeve 53 inside the regulator body 100 and the outer sleeve 58 outside the regulator body 100, respectively. During the inspection, unqualified regulator bodies 100 can be removed by a robotic arm or manually. Specifically, the plate frame 51 is driven to move downward by the electric push rod 18, and the plate frame 51 drives the mounting plate 52 to move synchronously. The inner sleeve 53 at the bottom of the mounting plate 52 will be inserted from the top of the regulator body 100. During the insertion process, the inner diameter of the regulator body 100 is inspected by the detection head 55 at the bottom of the mandrel 54. The outer diameter of the detection head 55 meets the diameter required for the water inlet core assembly. When inspecting the inner diameter, if the inner diameter of the regulator body 100 is relatively large, the inner diameter of the regulator body 100 will be inspected. When the detection head 55 moves downward, it will be obstructed. At this time, the detection head 55 pushes the spindle 54 to move upward, so that the spindle 54 exerts pressure on the detection sensor 57 on the bottom side of the plate frame 51. By collecting the pressure received by the detection sensor 57, it reflects whether the inner diameter of the regulator body 100 is qualified (if the detection sensor 57 is a displacement sensor, it can be judged by detecting the displacement of the spindle 54). At this time, the plate frame 51 moves upward, causing the inner sleeve 53 to disengage from the inside of the regulator body 100. Then, the unqualified regulator body 100 is removed by a robotic arm or manually, and then the detection is carried out again. During the detection process, the regulator body 100 behind continues to be fed to the top of the support plate 34 by a robotic arm or manually. The feeding work can be carried out at the same time as the detection, ensuring the detection efficiency. After the detection, the detection head 55 is reset to the detection origin relative to the inner sleeve 53 under the action of the spring B56. Simultaneously, the mounting plate 52 drives the outer sleeve 58 to be positioned outside the regulator body 100. As the outer sleeve 58 moves downwards and fits onto the outside of the regulator body 100, the outer diameter of the regulator body 100 is detected by the detection protrusion 512 on the inner side of the arc-shaped sliding plate 511. Several fins 103 are provided on the outer side of the regulator body 100. If the outer diameter of the fins 103 is too large, the fins 103 will be damaged during the downward movement of the detection protrusion 512. As the fins continue to move downwards, the subsequent starting spring C513 continues to drive the turntable 46 to rotate, causing the turntable 46 to drive the regulator body 100 held by the clamping block 45 to rotate. When the fin 103 moves, it will cause the detection protrusion 512 to rotate to one side, which will compress the spring C513 on one side. The spring C513 is arc-shaped and located inside the arc-shaped slide plate 511. The pressure of the spring C513 is collected by the sensor on the outside of the arc-shaped fixing plate 59, which can reflect whether the outer diameter of the fin 103 is qualified. If the outer diameter of the fin 103 is qualified during the downward movement of the detection protrusion 512, other positions of the fin 103 can be detected by the detection protrusion 512 during the subsequent rotation of the regulator body 100 to ensure that the outer periphery of the fin 103 meets the production requirements. S5. Unloading: The conveying component 2 continues to drive the bearing component 3 to move forward. When the bearing component 3 moves to one end of the conveying component 2, it begins to move downward, so that the regulator body 100 carried by the bearing component 3 is automatically unloaded by its own gravity. After unloading, the bearing component 3 continues to move to the top under the drive of the conveying component 2 to support the regulator body 100, realizing continuous feeding detection and automatic unloading.

[0047] Its advantages include: by setting up a bearing component 3 to support the regulator body 100, and by transporting it to the bottom of the detection component 5 through the conveying component 2, the regulator body 100 is positioned by the positioning component 4 directly below the detection component 5, so that the regulator body 100 can be coaxially positioned with the detection component 5, which can effectively reduce manual intervention and improve detection efficiency and accuracy; by combining continuous feeding and automatic unloading, not only is the operation cycle shortened, but the automation level of the production line is also significantly improved, meeting the needs of modern industry for high-efficiency and high-quality production.

[0048] When the positioning component 4 of the regulator-based detection device proposed in this study performs a positioning operation on the regulator body 100, the motor B413 drives the gear 412 to rotate. This rotation is transmitted to the turntable 46 via the gear ring B411, causing it to rotate synchronously. As the turntable 46 rotates, the arc-shaped hole 47 on its inner side drives the sliding column 48 to move along a preset trajectory, thereby pushing the slider 44 to move linearly along the limit rod 43. Since the sliding column 48 is fixedly connected between the slider 44 and the clamping block 45, this mechanical transmission process ensures that the clamping block 45 can achieve high-precision concentric clamping or releasing actions. In addition, when one of the turntables 46 rotates, the gear ring A49 on the outer side drives the other turntables 46 to rotate synchronously, realizing the parallel positioning of multiple regulator bodies 100 and significantly improving the working efficiency of the detection system. During the concentric clamping of the regulator body 100 by the clamping block 45, the vertical shaft 42 remains stationary due to the gravity of the bottom braking element counterweight 415, while the angle sensor 414 at its top monitors the rotation angle of the turntable 46 in real time. When the clamping block 45 contacts the outer ring 102 at the bottom of the regulator body 100, the vertical shaft 42 drives the counterweight 415 to rotate together with the continuous drive of the motor B413. The change in the detection value of the angle sensor 414 can provide real-time feedback on the clamping force of the clamping block 45 on the insertion end 101, effectively preventing overpressure damage. After clamping is completed, the regulator body 100 can be driven to rotate continuously, providing conditions for subsequent all-round inspection processes. After the testing process is completed, the turntable 46 rotates in the opposite direction to drive the clamping block 45 to release and position synchronously. Since the clamping block 45 adopts four sets of symmetrical arrangement and the axis of the limit rod 43 is designed to be at a 45° angle with the conveying direction of the regulator body 100, it can ensure that the clamping block 45 automatically completes the avoidance action of the insertion end 101 after the positioning is released, ensuring that the regulator body 100 can smoothly enter the next process.

[0049] The technical solution of this positioning mechanism has the following significant advantages: One advantage is that the rotation of the turntable 46 drives the clamping block 45 through the inner arc-shaped hole 47 to achieve synchronous clamping in the same direction, thus ensuring the coaxiality accuracy of the positioning process.

[0050] Secondly, the linkage design of multiple turntables 46 enables parallel positioning operations of multiple regulator bodies 100, which improves work efficiency while ensuring the synchronization and consistency of positioning actions.

[0051] Thirdly, the angled layout design of the clamping block 45 and the limiting rod 43 enables the automatic avoidance of the regulator body 100 after the positioning is released, which simplifies the subsequent conveying process and improves the smoothness of system operation.

[0052] Fourthly, by using a vertical shaft 42 in conjunction with a counterweight 415, the vertical shaft 42 can be kept stationary during the positioning process of the turntable 46 driving the clamping block 45. After the clamping block 45 is clamped and positioned with the regulator body 100, the clamping block 45 serves as an intermediate structure, allowing the turntable 46 to drive the regulator body 100 to rotate in the positioning state for subsequent outer diameter detection work. At the same time, it can prevent overpressure on the regulator body 100.

[0053] In actual use, if the top of the support plate 34 only supports one regulator body 100, writing fluid can be delivered through the conveying pipe 16 inside the detection component mounting frame 11 after detection. The writing fluid is controlled by an electric valve to spray from the nozzle 17 to the outside of the regulator body 100, so as to automatically mark the unqualified regulator body 100. The marked regulator body 100 is automatically unloaded with the conveying component 2. In the subsequent assembly process, the regulator body 100 is rejected and screened according to the marking, which can reduce the intervention of robotic arms or manual labor and reduce the cost of use.
