Description

Technical Field

[0001] The present invention relates to the technical field of on-line detection, and particularly to an on-line detection device for the copper layer thickness of copper-clad steel materials. Background Art

[0002] Copper-clad steel material is a dense metallurgical composite material formed by copper coating on the surface of a steel core, and its main component is the steel core covered by copper. This composite conductor has both the high strength, high elasticity, high thermal resistance and high magnetic conductivity characteristics of steel, and the good electrical conductivity and excellent corrosion resistance of copper, and is a high-quality grounding material. The copper layer thickness of copper-clad steel materials directly affects their service life. If the copper layer thickness of some copper-clad steel materials is too thin due to the offset of the steel core during the production process, its actual service life will be lower than the expected life. Therefore, it is necessary to detect the copper layer thickness of copper-clad steel materials in real time during the production process to ensure the uniformity of the copper layer thickness of copper-clad steel materials.

[0003] For the detection of the copper layer thickness during the production of copper-clad steel, the cutting sampling method is often used for detection. This detection method not only damages the finished products that have been produced, but also has a long detection interval time and poor real-time feedback ability for the position of the steel core during the production process.

[0004] Chinese Utility Model Patent: The publication number is "CN214843104U", and the name is "A thickness detection device for a roll silicon carbide composite coating", which discloses a thickness detection device for a roll silicon carbide composite coating, including a base. An installation groove is provided on the base, and rotating shafts are rotatably installed on the corresponding inner side walls of the installation groove. The number of rotating shafts is two groups and they are arranged in parallel and corresponding. Transmission gears and transmission drums are respectively welded and installed on the outer side walls of the rotating shafts. A transmission chain is sleeved on the transmission gear, and the transmission chain is meshed with the transmission gear. The roll can be fixed and turned over at a fixed position through the shaft card slot, effectively preventing the displacement of the roll and avoiding inaccurate measurement. Through the data connection setting between the central controller and the detection host, the data can be effectively recorded, observed and called. At the same time, with the slide-type design of the transmission gear, transmission chain and transmission drum, it is convenient to turn over the roll and improve the convenience of detecting the coating thickness on different surfaces of the roll. This technical solution has a simple structure, saves time and effort, and can improve the detection efficiency and the practicability of the device. However, this technical solution is only applicable to cylindrical products of a certain model length, and cannot be applied to cylindrical products of different model lengths, nor can it provide real-time feedback on the position of cylindrical products during the production process.

[0031] The advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments, which are given only as examples with reference to the accompanying drawings.

[0032] As Figures 1 to 10As shown in the figure, the present invention provides an on-line detection device for the copper layer thickness of a copper-clad steel material, including a resetable base 2, which is used to push the device installed thereon to the initial position, and the resetable base 2 is arranged along the axial direction of the copper-clad steel material 1. Above the resetable base 2, there are a sliding tray 3, an alignment detection part housing 4, an alignment clamping mechanism 5 and an internal movable detection mechanism 6. The sliding tray 3 is slidably connected to the resetable base 2, and the alignment detection part housing 4 is slidably connected to the sliding tray 3. The resetable base 2 includes a base housing 8, a guide rail A9 and a slider A10. The sliding tray 3 is installed on the resetable base 2 through the slider A10 and the guide rail A9. The guide rail A9 is horizontally arranged and parallel to the axis direction of the copper-clad steel material 1. The alignment detection part housing 4 is installed on the sliding tray 3 through a slider B23 and a guide rail B22. The guide rail B22 is horizontally arranged and perpendicular to the guide rail A9. The alignment clamping mechanism 5 is fixed on both sides of the alignment detection part housing 4 along the axial direction of the copper-clad steel material 1. The internal movable detection mechanism 6 is installed inside the alignment detection part housing 4 through a slider C29 and a guide rail C30. The guide rail C30 is vertically arranged. The on-line detection device further includes a top cylinder 7, which is arranged above the alignment detection part housing 4, and the output end of the top cylinder 7 penetrates through the alignment detection part housing 4 and is fixedly connected to the internal movable detection mechanism 6.

[0033] The alignment clamping mechanism 5 is used to clamp the copper-clad steel material 1 while adjusting the relative position between the alignment detection part housing 4 and the copper-clad steel material 1.

[0034] The internal movable detection mechanism 6 and the top cylinder 7 are used to complete the adjustment of the detection probe in the vertical direction. At the same time, the copper layer thickness of 4 points on the same cross-section of the copper-clad steel material 1 is measured.

[0035] Such as Figure 1 、 Figure 3 、 Figure 5 and Figure 8As shown in the figure, in order to achieve the purpose of following detection and centering, the present invention adopts the following scheme: The centering detection unit housing 4 is installed on the sliding tray 3 through the guide rail B22 and the slider B23, so that the centering detection unit housing 4 can be horizontally adjusted relative to the copper-clad steel material 1. The sliding tray 3 is installed on the resetable base 2 through the guide rail A9 and the slider A10, so that the centering detection unit housing 4 can move together with the sliding tray 3 in the axial direction of the copper-clad steel material 1. The centering detection unit housing 4 includes a bottom plate 48, a top plate 46, a vertical plate A47 and a vertical plate B49. The vertical plate A47 is fixed on the opposite sides of the bottom plate 48, and the centering clamping mechanism 5 is fixed on the vertical plate A47. The vertical plate B49 is fixed at the center of the other two sides of the bottom plate 48. The top plate 46 is arranged away from the bottom plate 48 and is fixedly connected to the vertical plate A47 and the vertical plate B49. The centering clamping mechanism 5 is fixed at the central position of the vertical plate A47, and is used for clamping the copper-clad steel material 1 while adjusting the relative position between the centering detection unit housing 4 and the copper-clad steel material 1, so as to ensure that the copper-clad steel material 1 is in the horizontally centered position of the centering detection unit housing 4 during the detection process. When the centering clamping mechanism 5 clamps the copper-clad steel material 1, it drives the centering detection unit housing 4 and the sliding tray 3 to perform synchronous movement relative to the copper-clad steel material 1 on the resetable base 2, thereby achieving the purpose of following detection. When the centering clamping mechanism 5 clamps the copper-clad steel material 1, it drives the centering detection unit housing 4 to perform horizontal movement relative to the copper-clad steel material 1 on the sliding tray 3, thereby achieving the purpose of horizontal centering.

[0036] As Figure 1 , Figure 3 and Figure 4 shown in the figure, the centering clamping mechanism 5 includes a cylinder jaw 24, an L-shaped extension block 25, a position adjustment block 26, an anti-slip pad fixing block 27 and an anti-slip pad 28. The L-shaped extension block 25 is installed on the two clamping heads on both sides of the cylinder jaw 24. The position adjustment block 26 is installed on the L-shaped extension block 25 and is used to adjust the clamping range of the centering clamping mechanism 5. The anti-slip pad fixing block 27 is installed on the position adjustment block 26, and the anti-slip pad 28 is installed on the anti-slip pad fixing block 27. Preferably, a pressure sensor can also be set on the anti-slip pad 28 to determine whether the clamping force is sufficient to make the centering detection unit housing 4 follow the movement of the copper-clad steel material 1.

[0037] As Figure 5 shown in the figure, the internal movable detection mechanism 6 is installed inside the centering detection unit housing 4 through the guide rail C30 and the slider C29, so that the internal movable detection mechanism 6 can move in the vertical direction relative to the copper-clad steel material 1. The top cylinder 7 is installed on the top of the centering detection unit housing 4 and is connected to the internal movable detection mechanism 6, and is used to push the internal movable detection mechanism 6 to perform vertical movement relative to the copper-clad steel material 1.

[0038] As Figure 3 andFigure 6 As shown, the internal activity detection mechanism 6 includes an internal activity part frame 41 that is integrally square-ring-shaped. The internal activity part frame 41 is sleeved on the copper-clad steel material 1, that is, the internal activity detection mechanism 6 is arranged perpendicular to the axis direction of the copper-clad steel material 1. At the top of the internal activity detection mechanism 6, an infrared proximity sensor 40, a telescopic detection probe B 38, and a pressure sensor 39 are sequentially arranged along the axis direction of the copper-clad steel material 1; at the bottom of the internal activity detection mechanism 6, an infrared proximity sensor 40, a telescopic detection probe A 37, and a pressure sensor 39 are sequentially arranged along the axis direction of the copper-clad steel material 1. Both the infrared proximity sensor 40 and the pressure sensor 39 are fixed to the bottom of the internal activity detection mechanism 6 through a support column A 35 and a support column mounting block A 33; symmetrically, both the infrared proximity sensor 40 and the pressure sensor 39 are fixed to the top of the internal activity detection mechanism 6 through a support column B 36 and a support column mounting block B 34. The telescopic detection probe A 37 is fixed to the bottom of the internal activity detection mechanism 6 through the support column mounting block A 33, and the telescopic detection probe B 38 is fixed to the top of the internal activity detection mechanism 6 through the support column mounting block B 34. The infrared proximity sensor 40 and the pressure sensor 39 are used to provide a stop signal when the internal activity detection mechanism 6 completes its movement in the vertical direction relative to the copper-clad steel material 1.

[0039] As Figure 5 shown, the internal activity detection structure 6 further includes a detection probe A 32. The detection probe A 32 is horizontally arranged in the middle of the internal activity part frame 41 in the vertical direction. The number of the detection probes A 32 is two, and they are symmetrically arranged with respect to the center of the internal activity part frame 41. The detection probe A 32 is fixedly connected to the internal activity part frame 41 through a small cylinder 31. The fixed end of the small cylinder 31 is fixedly connected to the internal activity part frame 41, and the output end of the small cylinder 31 is fixedly connected to the detection probe A 32. The detection probe A 32 is used to measure the copper layer thickness at two points in the horizontal direction of the copper-clad steel material 1. By adjusting the length of the support column A 35, the top cylinder 7 can be made to complete the purpose that the detection probes A 32 on both sides of the internal activity detection mechanism 6 are centered in the vertical direction with respect to the copper-clad steel material 1 when the internal activity detection mechanism 6 is pushed by the top cylinder 7 to move until the pressure sensor 39 is in full contact with the copper-clad steel material 1.

[0040] As Figure 5 and Figure 6As shown in the figure, to achieve the purpose of 4-point detection, the present invention adopts the following solution: The telescopic detection probe B38 is installed on the top of the internal movable part frame 41 through the support column mounting block B34. The static length after the combination installation of the support column mounting block B34 and the telescopic detection probe B38 is longer than the length after the combination installation of the support column mounting block B34, the support column B36, and the pressure sensor 39. When the top cylinder 7 pushes the internal movable detection mechanism 6 downward until the pressure sensor 39 is in full contact with the copper-clad steel material 1, the telescopic detection probe B38 achieves full contact with the copper-clad steel material 1 and completes the point measurement above the copper-clad steel material 1. After the point detection above the copper-clad steel material 1 is completed, the small cylinders 31 on both the left and right sides of the internal movable detection mechanism 6 push the detection probe A32 towards the copper-clad steel material 1 to complete the point measurement on both the left and right sides of the copper-clad steel material 1 and retract after the measurement is completed. The maximum extended distance of the small cylinder 31 is longer than the distance required when the detection probe A32 is in full contact with the copper-clad steel material 1. By adjusting the air pressure in the small cylinder 31, after the detection probe A32 is in full contact with the copper-clad steel material 1, the small cylinder 31 can maintain the contact between the detection probe 32 and the copper-clad steel material 1 without damaging the detection probe A32 due to excessive pressure. The telescopic detection probe A37 is fixed to the bottom of the internal movable part frame 41 through the support column mounting block A33. The static length after the combination installation of the support column mounting block A33 and the telescopic detection probe A37 is longer than the length after the combination installation of the support column mounting block A33, the support column A35, and the pressure sensor 39. When the top cylinder 7 pulls the internal movable detection mechanism 6 upward until the lower pressure sensor 39 is in full contact with the copper-clad steel material 1, the telescopic detection probe A37 achieves full contact with the copper-clad steel material 1 and completes the point measurement below the copper-clad steel material 1.

[0041] As Figure 7 shown, the structures of the telescopic detection probe A37 and the telescopic detection probe B38 are the same, and both include a support column C42, a spring 43, a detection probe B44, and a limit pin 45. Both ends of the support column C42 are fixedly connected to the mounting block and slidably connected to the detection probe B44. A groove is provided at one end of the detection probe B44 connected to the support column C42, and the detection probe B44 extends into the groove. A spring 43 is provided between the support column C42 and the detection probe B44. A limit groove is axially provided at one end of the support column C42 close to the detection probe B44. One end of the limit pin 45 is fixedly connected to the detection probe B44, and the other end is clamped in the limit groove of the support column C42. The telescopic detection probe A37 and the telescopic detection probe B38 achieve the purpose of telescoping through the cooperation of the support column C42, the spring 43, the limit pin 45, and the detection probe B44.

[0042] As Figure 8As shown in the figure, in order to ensure that there are no sharp edges and protruding parts on the outside of the centering detection unit housing 4, a mutually matching card slot can be provided at the connection between the vertical plate A47 and the top plate 46, and grooves are opened at corresponding positions in the middle of the top plate 46 and the bottom plate 48 for mating with the vertical plate B49.

[0043] As Figure 1 , Figure 2 , Figure 9 and Figure 10 shown, in order to achieve the purpose of resetting the detection device, the present invention adopts the following solution: The resetable base 2 includes a synchronous belt 11 and two synchronous pulleys 16. One of the synchronous pulleys 16 is installed at one end of the base housing 8 along the axis direction of the copper-clad steel material 1 through a bearing support seat 13, a bearing 14 and a shaft A15, and the other synchronous pulley 16 is installed at the other end of the base housing 8 along the axis direction of the copper-clad steel material 1 through a bearing support seat 13, a bearing 14 and a shaft B21. The synchronous belt 11 is sleeved on the two synchronous pulleys 16. The resetable base 2 further includes a reset mechanism upper clamping plate 17, a reset mechanism lower clamping plate 18 and a limit baffle 12. The reset mechanism upper clamping plate 17 and the reset mechanism lower clamping plate 18 are installed on the synchronous belt 11 for synchronous movement with the synchronous belt 11. The reset mechanism upper clamping plate 17 is simultaneously installed above the resetable base 2 through a slider A10 and a guide rail A9. The limit baffle 12 is installed on the base housing 8 and distributed on both sides of the guide rail A9 for limiting the movement range of the resetable mechanism upper clamping plate 17 and the sliding tray 3. The limit baffle 12 is also installed on the resetable mechanism upper clamping plate 17 for pushing the sliding tray 3. The resetable base 2 further includes a stepping motor 19. The stepping motor 19 is installed on a reserved notch at one end of the base housing 8 along the axis direction of the copper-clad steel material 1. The stepping motor 19 is connected to the shaft B21 through a coupling 20 for driving the synchronous pulley 16 to move, and then driving the synchronous belt 11 and the reset mechanism upper clamping plate 17 installed on the synchronous belt 11 to move. After completing the measurement of the points below the copper-clad steel material 1, the top cylinder 7 pushes the internal movable detection mechanism 6 until the pressure sensor 39 and the infrared proximity sensor 40 transmit predetermined values. At the same time, the centering and clamping mechanism 5 is loosened, and the centering detection unit housing 4 stops synchronous movement in the movement direction relative to the copper-clad steel material 1. Then, the stepping motor 19 drives the synchronous pulley 16 to drive the synchronous belt 11 and the reset mechanism installed on the synchronous belt 11 to move, and pushes the centering middle part housing 4 to the initial position.

[0044] In addition to the above embodiments, the present invention may also have other embodiments. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
