Description

Technical Field

[0001] This invention relates to the technical field of laser measuring instruments, specifically a laser measuring instrument for three-proof fabrics. Background Technology

[0002] Three-proof fabric is a specially treated fabric with waterproof, oil-proof, and stain-proof functions. In the production and processing process, laser measuring instruments are often used to accurately measure the size, thickness, and surface quality of the fabric to ensure its performance. However, existing laser measuring instruments have certain defects in use, especially when adjusting the balance of the main body of the laser measuring device. Usually, it is necessary to adjust the rotating blocks on both sides in sequence to achieve horizontal adjustment, which makes the overall operation relatively cumbersome and inconvenient.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent CN221992626U, published on 2024-11-12) provides a precision measuring device for interior decoration design. This device includes a base plate with two sets of screws rotatably connected to it via bearings. Each set of screws has a grooved wheel fixedly attached to it, and the two sets of grooved wheels are rotatably connected via a belt. Each set of screws has a threaded sleeve threaded to its outer wall, and a rod is fixedly attached to the top of each threaded sleeve. An inclined block is attached to the top of each set of inclined blocks, and a placement plate is fixedly attached to the top of each set of inclined blocks. This invention utilizes the transmission of the two sets of grooved wheels and the belt. When the two sets of screws rotate synchronously, the two sets of rods can be driven to move synchronously laterally. At this time, the two sets of rods will move on two inclined blocks placed in opposite directions, thereby rotating the placement plate to one side or the other. This allows for certain adjustments to the placement plate and the laser measuring instrument. The horizontal adjustment of the degree ensures measurement accuracy while being relatively convenient to operate. Existing technology two (Chinese patent CN212988276U, published on April 16, 2021) describes a line laser flatness inspection machine, which includes a worktable. A support is provided on the bearing surface of the worktable. A fixed block is slidably disposed on one side of the support. A sliding component for driving the fixed block to slide is provided on the support. A fixed plate is slidably disposed on the side of the fixed block away from the support. A moving component for driving the fixed plate to move towards or away from the worktable is provided on the fixed block. A fixed seat is disposed on the side of the fixed plate away from the fixed block. A laser measuring instrument for inspecting the gap of the test piece is rotatably disposed at the bottom of the fixed seat. A rotating component for driving the laser measuring instrument to rotate is disposed at the top of the fixed seat.

[0004] While existing technologies improve overall operational efficiency through multiple mechanical components and transmission systems, their relatively complex structure may increase the difficulty of manufacturing and installation. Furthermore, the multiple mechanical components and transmission systems occupy a lot of space, limiting the applicability of the equipment. The laser measuring instrument is often exposed to dust and impurities during operation, which may interfere with the accuracy of laser measurement and thus affect the reliability of the measurement data.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing laser measuring instrument for three-proof fabrics. Therefore, we proposed that a laser measuring instrument for three-proof fabrics can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a laser measuring instrument for three-proof fabrics, in order to solve the problems mentioned in the background art. Currently, the market has improved overall operating efficiency through multiple mechanical components and transmission systems, but its structure is relatively complex, which may increase the difficulty in the manufacturing and installation process. In addition, multiple mechanical components and transmission systems occupy a lot of space, which limits the applicability of the equipment. The laser measuring instrument is often exposed to dust and impurities during operation, and the impurities may interfere with the accuracy of laser measurement, thereby affecting the reliability of the measurement data.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a laser measuring instrument for three-proof fabric, comprising a frame and a measuring component. A robotic arm is mounted on the frame, and a measuring box is connected to the end of the robotic arm. The measuring component is installed inside the measuring box, and a motor is installed inside the measuring box. A rotating shaft is connected to the output end of the motor, and a gear is mounted on the outer side of the rotating shaft. A gear ring is meshed with the side end of the gear, and a protective plate is meshed with the inner side of the gear ring. An arc block is mounted on the gear ring. An arc groove is formed on the surface of the measuring box, and the arc block is slidably connected inside the arc groove. A fabric limiting structure is mounted on the frame, and a support frame is provided on the side end of the measuring box. A cleaning roller is mounted on the support frame. The robotic arm on the frame can flexibly adjust the spatial position of the measuring box connected to its end, moving the measuring component inside to the area to be measured on the three-proof fabric, realizing multi-position measurement. The cleaning roller facilitates cleaning of the fabric surface, preventing dust on the fabric surface from affecting the accuracy of laser measurement.

[0008] Preferably, the bottom end of the measuring component is connected to a snap-fit ​​block via a threaded post, and a limit assembly is installed inside the measuring box, the limit assembly including a support seat installed inside the measuring box.

[0009] Preferably, the support base has a threaded groove, and the support base has a snap-fit ​​seat inside, and the snap-fit ​​seat has a snap-fit ​​groove that matches the snap-fit ​​block.

[0010] Preferably, a support plate is installed inside the measuring box, and a sliding groove is formed on the surface of the support plate. A slider is slidably connected inside the sliding groove. The slider is connected to the bottom of the clamping seat through a rotating plate. A clamping block is installed on the slider. The clamping block on the slider clamps the side wall of the measuring piece, ensuring stable installation of the measuring piece, avoiding shaking during measurement, and enhancing the adaptability of the equipment to different measuring pieces.

[0011] Preferably, an annular pipe is installed inside the measuring box, the annular pipe is located outside the measuring element, a first through hole is opened on the inner side of the annular pipe, and a conveying pipe is connected to the annular pipe, the conveying pipe extending through to the outside of the measuring box.

[0012] Preferably, a sleeve is fitted around the outer side of the cleaning roller, the inner cavity of the sleeve is connected to the conveying pipe, the inner cavity of the sleeve is connected to the inner cavity of the cleaning roller, and a second through hole is opened on the outer side of the cleaning roller. Airflow enters the inner cavity of the cleaning roller through the sleeve and then sprays out from the second through hole on the outer side of the cleaning roller. In conjunction with the rolling of the cleaning roller, on the one hand, the roller body wipes the dust on the surface of the fabric, and on the other hand, the airflow blows away residual impurities, ensuring that the fabric in the measurement area is clean and improving the reliability of the measurement data.

[0013] Preferably, a rotating rod is connected to the outside of the rotating shaft via a belt and pulley structure. The rotating rod is located inside the measuring box, and a cam is sleeved on the outside of the rotating rod.

[0014] Preferably, an auxiliary component is installed inside the measuring box. The auxiliary component includes a movable part installed inside the measuring box, the movable part being located at the cam side end and extending through to the outside of the measuring box.

[0015] Preferably, a spring is sleeved on the outside of the moving part, and a striking plate is installed on the side end of the moving part. The striking plate is located on the side end of the support frame. The moving part moves back and forth under the elastic reset action of the spring, driving the striking plate on the side end to repeatedly strike the support frame. The vibration generated by the striking is transmitted to the cleaning roller, improving the cleaning effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the laser measuring instrument for the three-proof fabric can flexibly adjust the spatial position of the measuring box connected to the end of the frame, realizing multi-position measurement; the protective plate can be easily opened during measurement and closed when not measuring, extending the service life of the measuring component. The specific details are as follows:

[0017] The protective plate opens and closes through the meshing of the gear ring and gear. It opens during measurement to ensure unobstructed path and closes when not in use to prevent dust and impurities from contaminating it. The cooperation between the arc block and the arc groove ensures that the protective plate moves smoothly, avoiding the impact of shaking during the opening and closing process on the measuring parts, extending the service life of the measuring parts, and reducing the maintenance cost of the equipment.

[0018] The fabric limiting structure fixes the fabric through both clamping and tensioning, avoiding deviation caused by external forces and reducing the interference of wrinkles on the test data. This allows the measuring parts to obtain data with a unified benchmark when measured at different positions, greatly improving the accuracy and consistency of the measurement and solving the measurement error problem caused by the instability of the fabric.

[0019] The robotic arm on the frame can flexibly adjust the spatial position of the measuring box, enabling multi-position measurement of the measuring parts. This effectively avoids the inconvenience of single-axis movement, enhances the versatility and flexibility of the equipment, reduces the space occupation caused by setting up multiple mechanical parts, and lowers the difficulty and cost of maintenance.

[0020] The measuring component is doubly fixed by the engagement of the threaded post and the threaded groove, and the insertion of the snap-fit ​​block and the snap-fit ​​groove. In addition, the clamping block provides auxiliary clamping, which greatly improves the stability of the installation and ensures the stability during measurement.

[0021] The cleaning roller rubs the fabric surface while the airflow from the second through hole blows away residual impurities. The airflow from the annular pipe also cleans and cools the surface of the measuring piece. The vibration of the impact plate is transmitted to the cleaning roller, enhancing the cleaning effect and effectively improving the reliability of the measurement data. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: In this example, the protective plate 9 is opened during measurement to expose the measuring port of the measuring element 4, and closed when not in use to prevent dust and impurities from entering the measuring box 3 and contaminating the measuring element 4. This ensures unobstructed measurement path during measurement and provides effective protection for the measuring element 4 when not in use, extending its service life and reducing maintenance costs. Figures 1-5The technical solution shown includes a frame 1 and a measuring component 4. A robotic arm 2 is mounted on the frame 1, and a measuring box 3 is connected to the end of the robotic arm 2. The measuring component 4 is installed inside the measuring box 3, and a motor 5 is installed inside the measuring box 3. A rotating shaft 6 is connected to the output end of the motor 5. A gear 7 is mounted on the outside of the rotating shaft 6, and a gear ring 8 is meshed with the side end of the gear 7. A protective plate 9 is meshed with the inside of the gear ring 8, and an arc block 10 is mounted on the gear ring 8. An arc groove 11 is formed on the surface of the measuring box 3, and the arc block 10 is slidably connected inside the arc groove 11. A fabric limiting structure 12 is mounted on the frame 1, and the measuring box... A support frame 13 is provided on the side end, and a cleaning roller 14 is installed on the support frame 13. The three-proof fabric is installed on the frame 1 through the fabric limiting structure 12. The fabric limiting structure 12 is stably fixed by clamping and tensioning, which not only avoids the fabric from shifting due to external force during the measurement process and provides a stable measurement benchmark for the measuring part 4, but also reduces the problem of inaccurate test data caused by fabric wrinkles, effectively improving the accuracy and consistency of the measurement. The robotic arm 2 on the frame 1 can flexibly adjust the spatial position of the measuring box 3 connected to the end, and move the measuring part 4 inside to the three-proof fabric. The measurement area of ​​the fabric can be measured at multiple positions, breaking through the limitations of fixed measurement positions, enhancing the versatility and flexibility of the equipment, reducing the space occupation caused by setting up multiple mechanical parts, and reducing the difficulty and cost of maintenance. When the motor 5 is turned on, the output end of the motor 5 drives the rotating shaft 6 to rotate, and the gear 7 on the outside of the rotating shaft 6 rotates synchronously. The gear 7 meshes with the gear ring 8, driving the gear ring 8 to rotate. At this time, the gear ring 8 slides in the arc groove 11 of the measuring box 3 through the arc block 10, ensuring the smoothness of the opening and closing action of the protective plate 9. Since the inner side of the gear ring 8 meshes with the protective plate 9, the gear... When ring 8 rotates, it drives the protective plate 9 to open and close. The protective plate 9 can be opened during measurement to expose the measuring port of measuring component 4, and closed when not measuring to prevent dust and impurities from entering the measuring box 3 and contaminating the measuring component 4. This ensures that the measuring path is unobstructed during measurement and provides effective protection for the measuring component 4 when not in operation, extending the service life of the measuring component 4 and reducing maintenance costs. When the measuring box 3 is moved, the cleaning roller 14 on its side support frame 13 can easily clean the surface of the fabric to avoid dust on the fabric surface affecting the accuracy of laser measurement and clearing obstacles in advance for the measurement process.

[0038] Example 2: In this example, the bottom of the retaining base 19 is connected to the slider 21 via a rotating piece 20. The retaining base 19 rotates, causing the clamping block 24 on the slider 21 to clamp the side wall of the measuring piece 4, ensuring stable installation of the measuring piece 4, preventing shaking during measurement, and enhancing the adaptability of the equipment to different measuring pieces 4. Specifically, as shown... Figures 5-10As shown, the following is disclosed: the bottom end of the measuring component 4 is connected to a snap-fit ​​block 16 via a threaded post 15; a limiting assembly is installed inside the measuring box 3, including a support base 17 installed inside the measuring box 3, a threaded groove 18 on the support base 17, a snap-fit ​​seat 19 inside the support base 17, and a snap-fit ​​groove adapted to the snap-fit ​​block 16 on the snap-fit ​​seat 19; a support plate 22 is installed inside the measuring box 3, a sliding groove 23 is provided on the surface of the support plate 22, a slider 21 is slidably connected inside the sliding groove 23, the slider 21 is connected to the bottom of the snap-fit ​​seat 19 via a rotating piece 20, and a clamping block 24 is installed on the slider 21; the bottom end of the measuring component 4 is connected to the snap-fit ​​block 16 via the threaded post 15; during installation, the threaded post 15 and the threaded groove 18 of the support base 17 are initially fixed by thread engagement, while the snap-fit ​​block 16 is engaged. The locking mechanism further limits the movement within the locking groove of the locking seat 19. Since an elastic sleeve is provided at the connection between the locking block 16 and the locking groove of the locking seat 19, the connection not only makes the whole structure more stable, but also reduces the problem of the locking seat 19 being squeezed due to the continued rotation of the threaded column 15. The double fixing structure greatly improves the stability of the installation of the measuring component 4 and avoids the loosening problem that may occur with a single fixing method. As the locking seat 19 continues to rotate, since the bottom of the locking seat 19 is connected to the slider 21 through the rotating piece 20, the locking seat 19 rotates, causing the slider 21 to slide in the groove 23 of the support plate 22. This allows the clamping block 24 on the slider 21 to clamp the side wall of the measuring component 4, ensuring that the measuring component 4 is stably installed and avoiding shaking during measurement. This enhances the adaptability of the equipment to different measuring components 4 and ensures the stability during measurement.

[0039] Example 3: In this example, the airflow directly sweeps the surface of the measuring component 4, which not only avoids dust affecting the accuracy of laser measurement, but also facilitates cooling operations, preventing the measuring component 4 from affecting measurement accuracy due to high temperature. Specifically, as follows... Figure 5 , Figure 6 and Figures 11-13As shown, the following is disclosed: An annular pipe 26 is installed inside the measuring box 3, located outside the measuring element 4. A first through hole 27 is opened on the inner side of the annular pipe 26. A conveying pipe 25 is connected to the annular pipe 26, extending through to the outside of the measuring box 3. A sleeve 28 is fitted on the outer side of the cleaning roller 14, with its inner cavity connected to the conveying pipe 25 and the inner cavity of the cleaning roller 14. A second through hole 29 is opened on the outer side of the cleaning roller 14. The outer side of the rotating shaft 6 is connected to a pulley via a belt. The measuring box 30 is connected to a rotating rod 31, which is located inside the measuring box 3. A cam 32 is sleeved on the outside of the rotating rod 31. An auxiliary component is installed inside the measuring box 3, including a moving part 33 installed inside the measuring box 3. The moving part 33 is located on the side of the cam 32 and extends through to the outside of the measuring box 3. A spring 35 is sleeved on the outside of the moving part 33. A striking plate 34 is installed on the side of the moving part 33 and is located on the side of the support frame 13. An external air source is supplied to the annular pipe 26 through the delivery pipe 25. Airflow is delivered, with the first through hole 27 on the inner side of the annular pipe 26 facing the measuring piece 4. The airflow directly blows the surface of the measuring piece 4, which not only avoids dust affecting the accuracy of laser measurement, but also facilitates cooling operations and prevents the measuring piece 4 from affecting the measurement accuracy due to high temperature. At the same time, the conveying pipe 25 delivers airflow to the sleeve 28 on the outer side of the cleaning roller 14. The airflow enters the inner cavity of the cleaning roller 14 through the sleeve 28, and then sprays out from the second through hole 29 on the outer side of the cleaning roller 14. With the rolling of the cleaning roller 14, on the one hand, the roller body wipes the dust on the surface of the fabric, and on the other hand, the airflow blows away residual impurities, ensuring that the fabric in the measurement area is clean and improving the reliability of the measurement data. When the rotating shaft 6 rotates, its outer side drives the rotating rod 31 to rotate through the belt and pulley structure 30. The cam 32 on the outer side of the rotating rod 31 rotates synchronously. When the cam 32 rotates, it periodically squeezes the moving part 33 of the auxiliary component. The moving part 33 moves back and forth under the elastic reset action of the spring 35, driving the side impact plate 34 to repeatedly strike the support frame 13. The vibration generated by the impact is transmitted to the cleaning roller 14, improving the cleaning effect.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
