Description

Technical Field

[0001] This invention relates to the field of optical measurement technology, specifically to a coating thickness measuring device for wear-resistant and corrosion-resistant metal modification processing. Background Technology

[0002] In the modification and processing of wear-resistant and corrosion-resistant metals, infrared thickness gauges are highly efficient tools for measuring coating thickness. Infrared thickness gauges work based on the principle of photothermal effect. They use modulated laser or LED pulses to heat the surface of the coating. The heat diffuses into the coating and is reflected when it reaches the interface between the coating and the substrate. This reflection is detected by the sensor in the measuring head. Since the coating thickness varies, the time for heat diffusion and reflection also varies. By measuring the phase shift or amplitude value of the infrared radiation and comparing it with the coating thickness value, the coating thickness can be calculated.

[0003] However, existing coating thickness measuring devices for wear-resistant and corrosion-resistant metal modification often encounter problems during use. These measurements frequently occur on industrial production lines (such as spraying lines and modification lines) or at heavy component inspection sites. During measurement, the infrared thickness gauge is moved by a moving module. During this movement, the measuring head is prone to collisions with transported metal components, tooling fixtures, and spraying equipment parts. Due to the lack of appropriate protection, the measuring head is easily damaged. Furthermore, collisions are not easily detected and repaired in a timely manner, thus affecting the accuracy of the measurement and its service life.

[0004] To address this, we propose a coating thickness measuring device for the modification and processing of wear-resistant and corrosion-resistant metals. Summary of the Invention

[0005] The purpose of this invention is to provide a coating thickness measuring device for the modified processing of wear-resistant and corrosion-resistant metals, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coating thickness measuring device for wear-resistant and corrosion-resistant metal modification processing, comprising an infrared thickness gauge mounted on a linear guide slide, wherein the infrared thickness gauge includes a main body and a measuring head, the measuring head integrating an infrared emitter assembly, an infrared receiver assembly, and an optical focusing assembly; the emitter assembly is used to emit infrared light of a specific wavelength, which is focused by the optical focusing assembly and irradiates the surface of the wear-resistant and corrosion-resistant coating; the infrared receiver assembly is used to receive and capture infrared signals reflected / transmitted by the coating, convert the light signals into electrical signals, and transmit them to the main body, and further includes: A protective mechanism is provided on the side wall of the measuring head to protect the measuring head.

[0007] Preferably, the protective mechanism includes an annular cover fitted onto the side wall of the measuring head, and the annular cover is connected to the bottom of the main body via a lifting mechanism. A heat-conducting plate is fixedly connected to the side wall of the annular cover near the measuring head, and a sealing gasket is fixedly connected to the side wall of the annular cover near the measuring head. The annular cover is filled with heat-conducting oil, and multiple anti-collision components are provided on the side wall of the annular cover.

[0008] By adopting the above technical solution, during measurement, the lifting mechanism drives the annular cover to move downward and bring the bottom of the annular cover close to the surface of the workpiece, thereby reducing the influence of external light and ensuring the accuracy of the measurement. Furthermore, when the measuring head is about to collide, the object will first collide with the anti-collision component, which can protect it.

[0009] Preferably, each of the anti-collision components includes a first fixed tube fixedly inserted into the side wall of the annular cover, and a piston slidably connected inside the first fixed tube. A guide rod is fixedly connected to the end of the piston, and the other end of the guide rod passes through the end of the first fixed tube and is connected to a rectangular cover through a buffer rod assembly. A rectangular plate is connected inside the rectangular cover through a telescopic mechanism, and a detection mechanism for detecting the movement of the piston is provided at the top of the annular cover.

[0010] By adopting the above technical solution, when the measuring head is about to collide, the colliding object will first collide with the rectangular cover and rectangular plate. At this time, the piston can be pushed to slide in the first fixed tube through the buffer rod assembly and guide rod, which can squeeze the heat transfer oil in the annular cover. At the same time, the buffer rod assembly deforms, thereby buffering the collision and reducing the force of the collision.

[0011] Preferably, the telescopic mechanism includes a first sleeve fixedly connected to the bottom of the rectangular cover, and a first sleeve rod is inserted inside the first sleeve. The upper end of the first sleeve rod is fixed to the bottom of the rectangular plate, and a first spring is sleeved on the side wall of the first sleeve.

[0012] By adopting the above technical solution, when the annular cover moves downward, the rectangular cover can be moved by the buffer mechanism. Furthermore, under the action of the first spring, the top of the rectangular plate can always be in contact with the bottom of the main body, ensuring the protective effect.

[0013] Preferably, the detection mechanism includes a second fixed tube fixedly inserted into the top of the annular cover, and a float plate is slidably connected inside the second fixed tube. The top of the second fixed tube is provided with a detection component for detecting the movement of the float plate.

[0014] By adopting the above technical solution, when the piston slides in the first fixed tube, it can squeeze the heat transfer oil in the annular shroud. After the heat transfer oil in the annular shroud is squeezed, it can push the float plate to move upward, and the rise and fall of the float plate can be detected by the detection component.

[0015] Preferably, the detection component includes a first fixing block fixedly connected to the top of the second fixing tube, and a lifting rod is inserted into the top of the first fixing block. The lower end of the lifting rod is fixed to the top of the float, and a disc is fixedly connected to the upper end of the lifting rod. A distance sensor is fixedly inserted into the bottom of the disc.

[0016] By adopting the above technical solution, when the float is raised or lowered, the disc and distance sensor can be moved by the lifting rod. The distance sensor can detect the change in distance between the disc and the first fixed block, thereby detecting the magnitude of the collision.

[0017] Preferably, the infrared thickness gauge further includes a sealing plate, which is rotatably connected to the side wall of the annular cover via a rotating mechanism. The side wall of the annular cover has an installation groove, and an electric heating block is provided in the installation groove.

[0018] By adopting the above technical solution, when the external ambient temperature is low during measurement, the electric heating block can be activated to heat the heat-conducting oil inside the annular cover. At this time, through the heat conduction effect of the heat-conducting plate, the measuring head and the space covered by the annular cover can be heated and kept warm, preventing water vapor from condensing on the measuring head and ensuring the accuracy of the measurement. During measurement, the sealing plate is rotated and opened by the rotating mechanism to ensure normal measurement by the measuring head. When not measuring, the sealing plate is rotated and closed by the rotating mechanism, and the bottom of the annular cover is sealed to protect the measuring head and ensure its measurement accuracy and service life.

[0019] Preferably, the rotating mechanism includes a second fixed block fixedly connected to the side wall of the annular cover, and a rotating block is rotatably connected to the bottom of the second fixed block via a rotating rod. The rotating block is fixed to the side wall of the sealing plate, and the rotation of the rotating rod is driven by a driving mechanism.

[0020] By adopting the above technical solution, the rotating rod is driven to rotate by the driving mechanism, and then the sealing plate is driven to rotate by the rotating block.

[0021] Preferably, the driving mechanism includes a groove formed on the side wall of the rotating rod, and the groove includes a spiral groove and a vertical groove that are adjacent to each other. A fixed rod is fixedly connected to the bottom of the main body, and a push pin is fixedly connected to the side wall of the fixed rod, and the push pin can slide in the groove.

[0022] By adopting the above technical solution, when the annular cover moves downward, the push pin slides along the spiral groove to the vertical groove. At this time, it can push the sealing plate to rotate and open along the rotating rod. When the annular cover moves upward, the push pin can slide along the vertical groove to the spiral groove. At this time, it can push the sealing plate to rotate and reset along the rotating rod and seal the bottom of the annular cover.

[0023] Preferably, the lifting mechanism includes a U-shaped plate fixedly connected to the bottom of the main body, and two second sleeve rods are fixedly connected to the bottom of the U-shaped plate. A second sleeve is sleeved on the side wall of each second sleeve rod, and the lower end of the second sleeve is fixed to the side wall of the annular cover through a connecting block. A second spring is sleeved on the side wall of each second sleeve. An electromagnet is fixedly connected to the bottom of the U-shaped plate, and an iron block is fixedly connected to the top of the connecting block.

[0024] By adopting the above technical solution, when no measurement is needed, the electromagnet is energized to attract the iron block, which can drive the annular cover to move upward through the connecting block. At the same time, the second spring is compressed. When the measurement is performed, the electromagnet is de-energized and no longer attracts the iron block. At this time, the connecting block can move downward under the action of the second spring, and drive the annular cover to move downward.

[0025] In summary, Advantage 1: When the infrared thickness gauge performs optical measurement of the coating thickness, it can protect the measuring head, so that it can be buffered before a collision occurs, avoiding damage to the measuring head due to the collision, and ensuring the accuracy of the measurement and the service life. Advantage 2: When the infrared thickness gauge performs optical measurement of the coating thickness, it can detect and alarm in time when a collision occurs, reminding maintenance personnel to carry out maintenance, avoiding damage to the measuring head due to collision, and ensuring the accuracy of measurement and service life.

[0027] 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.

[0028] Example 1 Please see Figures 1-7 The figure shows a coating thickness measuring device for wear-resistant and corrosion-resistant metal modification processing, including an infrared thickness gauge mounted on a linear guide slide 1. The infrared thickness gauge includes a main body 1101 and a measuring head 1102. The main body 1101 has a built-in infrared signal processing unit for receiving electrical signals transmitted from the measuring head 1102 and converting them into coating thickness data through preset algorithms, such as optical path difference calculation and temperature compensation algorithms. The measuring head 1102 integrates an infrared emitter assembly, an infrared receiver assembly, and an optical focusing assembly. The emitter assembly emits infrared light of a specific wavelength, which is focused by the optical focusing assembly and irradiates the surface of the wear-resistant and corrosion-resistant coating. The infrared receiver assembly receives and captures infrared signals reflected / transmitted by the coating, converts the light signals into electrical signals, and transmits them to the main body 1101. The device also includes: The protective mechanism, located on the side wall of the measuring head 1102, is used to protect the measuring head 1102. When performing optical measurements of coating thickness, it can protect the measuring head 1102, providing buffer protection before a collision occurs. Furthermore, it can detect and alarm in a timely manner, reminding maintenance personnel to perform maintenance, thus preventing damage to the measuring head 1102 due to collisions and ensuring the accuracy of the measurement and its service life.

[0029] The protective mechanism includes an annular cover 12 fitted onto the side wall of the measuring head 1102. The annular cover 12 is connected to the bottom of the main body 1101 via a lifting mechanism. A ring-shaped heat-conducting plate 13 is fixedly connected to the side wall of the annular cover 12 near the measuring head 1102, and a ring-shaped sealing gasket 16 is also fixedly connected to the side wall of the annular cover 12 near the measuring head 1102. There is a distance between the heat-conducting plate 13 and the measuring head 1102. Even if the annular cover 12 deforms during a collision, the heat-conducting plate 13 will not touch the measuring head 1102. At the same time, the sealing gasket 16 can also deform to buffer the impact. The annular cover 12 is filled with heat-conducting oil, and multiple anti-collision components are provided on the side wall of the annular cover 12. During measurement, the lifting mechanism moves the annular cover 12 downward, bringing the bottom of the annular cover 12 close to the surface of the workpiece. This reduces the influence of external light and ensures the accuracy of the measurement. Furthermore, when the measuring head 1102 is about to collide, the object will first collide with the anti-collision components, thus protecting it.

[0030] Each anti-collision component includes a first fixed tube 201 fixedly inserted into the side wall of the annular cover 12, and a piston 203 slidably connected inside the first fixed tube 201. A guide rod 202 is fixedly connected to the end of the piston 203, and the other end of the guide rod 202 passes through the end of the first fixed tube 201 and is connected to a rectangular cover 14 through a buffer rod assembly 204. A rectangular plate 15 is connected inside the rectangular cover 14 through a telescopic mechanism. A detection mechanism for detecting the movement of the piston 203 is provided on the top of the annular cover 12. When the measuring head 1102 is about to collide, the colliding object will first collide with the rectangular cover 14 and the rectangular plate 15. At this time, the piston 203 can be pushed to slide inside the first fixed tube 201 through the buffer rod assembly 204 and the guide rod 202, which can squeeze the heat transfer oil inside the annular cover 12. At the same time, the buffer rod assembly 204 deforms, thereby buffering the collision and reducing the force of the collision.

[0031] The telescopic mechanism includes a first sleeve 601 fixedly connected to the bottom of the rectangular cover 14, and a first sleeve rod 602 inserted inside the first sleeve 601. The upper end of the first sleeve rod 602 is fixed to the bottom of the rectangular plate 15, and a first spring 603 is sleeved on the side wall of the first sleeve 601. When the annular cover 12 moves downward, it can drive the rectangular cover 14 to move through the buffer mechanism. Under the action of the first spring 603, the top of the rectangular plate 15 can always be in contact with the bottom of the main body 1101 to ensure the protective effect.

[0032] The detection mechanism includes a second fixed tube 301 fixedly inserted into the top of the annular cover 12, and a float 302 slidably connected inside the second fixed tube 301. The top of the second fixed tube 301 is provided with a detection component for detecting the movement of the float 302. When the piston 203 slides inside the first fixed tube 201, it can squeeze the heat transfer oil inside the annular cover 12. When the heat transfer oil inside the annular cover 12 is squeezed, it can push the float 302 to move upward. The rise and fall of the float 302 can be detected by the detection component.

[0033] The detection assembly includes a first fixing block 401 fixedly connected to the top of the second fixing tube 301, and a lifting rod 402 is inserted into the top of the first fixing block 401. The lower end of the lifting rod 402 is fixed to the top of the float 302, and a disc 403 is fixedly connected to the upper end of the lifting rod 402. A distance sensor 404 is fixedly inserted into the bottom of the disc 403. When the float 302 is raised or lowered, the disc 403 and the distance sensor 404 can be moved by the lifting rod 402. The distance sensor 404 can detect the change in distance between the disc 403 and the first fixing block 401, thereby detecting the magnitude of the collision.

[0034] The infrared thickness gauge also includes a sealing plate 10, which is rotatably connected to the side wall of the annular cover 12 via a rotating mechanism. The side wall of the annular cover 12 has an installation groove 501, and an electric heating block 502 is installed in the installation groove 501. During measurement, when the external ambient temperature is low, the electric heating block 502 can be activated to heat the heat-conducting oil inside the annular cover 12. At this time, through the heat conduction effect of the heat-conducting plate 13, the measuring head 1102 and the space covered by the annular cover 12 can be heated and kept warm, preventing water vapor from condensing on the measuring head 1102 and ensuring the accuracy of the measurement. During measurement, the sealing plate 10 is rotated and opened by the rotating mechanism to ensure the normal measurement of the measuring head 1102. When not measuring, the sealing plate 10 is rotated and closed by the rotating mechanism, and the bottom of the annular cover 12 is sealed to protect the measuring head 1102 and ensure its measurement accuracy and service life.

[0035] The rotating mechanism includes a second fixing block 701 fixedly connected to the side wall of the annular cover 12, and a rotating block 703 is rotatably connected to the bottom of the second fixing block 701 via a rotating rod 702. The rotating block 703 is fixed to the side wall of the sealing plate 10, and the rotation of the rotating rod 702 is driven by a driving mechanism. The driving mechanism drives the rotating rod 702 to rotate, which in turn drives the sealing plate 10 to rotate via the rotating block 703.

[0036] The driving mechanism includes a groove formed on the side wall of the rotating rod 702, and the groove includes a spiral groove 801 and a vertical groove 802 that are adjacent to each other. A fixed rod 803 is fixedly connected to the bottom of the main body 1101, and a push pin 804 is fixedly connected to the side wall of the fixed rod 803. The push pin 804 can slide in the groove. When the annular cover 12 moves downward, the push pin 804 slides along the spiral groove 801 to the vertical groove 802. At this time, it can push the sealing plate 10 to rotate and open along the rotating rod 702. When the annular cover 12 moves upward, the push pin 804 can slide along the vertical groove 802 to the spiral groove 801. At this time, it can push the sealing plate 10 to rotate and reset along the rotating rod 702 and seal the bottom of the annular cover 12.

[0037] The lifting mechanism includes a U-shaped plate 904 fixedly connected to the bottom of the main body 1101, and two second sleeve rods 903 fixedly connected to the bottom of the U-shaped plate 904. A second sleeve 902 is sleeved on the side wall of each second sleeve rod 903, and the lower end of the second sleeve 902 is fixed to the side wall of the annular cover 12 through a connecting block 901. A second spring 905 is sleeved on the side wall of each second sleeve 902. An electromagnet 907 is fixedly connected to the bottom of the U-shaped plate 904, and an iron block 906 is fixedly connected to the top of the connecting block 901. When measurement is not required, the electromagnet 907 is energized to attract the iron block 906, which can drive the annular cover 12 to move upward through the connecting block 901. At the same time, the second spring 905 is compressed. When measurement is performed, the electromagnet 907 is de-energized and no longer attracts the iron block 906. At this time, the connecting block 901 can move downward under the action of the second spring 905, and drive the annular cover 12 to move downward.

[0038] Working principle: During use, the metal modified with wear-resistant and corrosion-resistant metal is transported. When measurement is required, the infrared thickness gauge is moved by the linear guide slide 1. The transmitter component in the measuring head 1102 emits infrared light of a specific wavelength, which is focused by the optical focusing component and irradiates the surface of the wear-resistant and corrosion-resistant coating. The infrared receiver component receives and captures the infrared signal reflected / transmitted by the coating and converts the light signal into an electrical signal and transmits it to the main body 1101, thereby realizing the measurement of the thickness of the metal coating modified with wear-resistant and corrosion-resistant metal.

[0039] Meanwhile, when the measurement is performed, the electromagnet 907 is de-energized and no longer attracts the iron block 906. At this time, the connecting block 901 can move downward under the action of the second spring 905, and drive the annular cover 12 to move downward, so that the bottom of the annular cover 12 is close to the surface of the workpiece, thereby reducing the influence of external light and ensuring the accuracy of the measurement.

[0040] In use, when the annular cover 12 moves downward, it can drive the rectangular cover 14 to move through the buffer mechanism. Furthermore, under the action of the first spring 603, the top of the rectangular plate 15 is always in contact with the bottom of the main body 1101. When the measuring head 1102 is about to collide, the object colliding will first collide with the rectangular cover 14 and the rectangular plate 15. At this time, the buffer rod assembly 204 and the guide rod 202 can push the piston 203 to slide within the first fixed tube 201, squeezing the heat transfer oil inside the annular cover 12. Simultaneously, the buffer rod assembly 204 deforms, thereby buffering the collision and reducing its impact. The impact force is measured, and when the heat transfer oil inside the annular cover 12 is squeezed, it can push the float 302 to move upward. At the same time, the lifting rod 402 drives the disc 403 and the distance sensor 404 to move. At this time, the distance sensor 404 can detect the change in distance between the disc 403 and the first fixed block 401, and thus detect the magnitude of the collision. At this time, the infrared thickness gauge can be stopped by the linear guide slide 1, and an external alarm can be triggered to remind maintenance personnel to carry out maintenance, so as to avoid damage to the measuring head 1102 due to the collision, protect it, and ensure the accuracy of the measurement and its service life.

[0041] Furthermore, when the infrared thickness gauge is moving during measurement, if the infrared thickness gauge shakes, the heat transfer oil inside the annular cover 12 will shake. At the same time, it can drive the float 302 to move up and down within the second fixed pipe 301, which in turn drives the disc 403 and the distance sensor 404 to move via the lifting rod 402. At this time, the movement of the float 302 can also be detected, thereby detecting the shaking amplitude of the infrared thickness gauge. When the shaking amplitude exceeds the required range, an external alarm will be triggered to remind maintenance personnel to carry out maintenance and ensure the accuracy of the measurement.

[0042] During measurement, when the external ambient temperature is low, the electric heating block 502 can be activated to heat the heat-conducting oil inside the annular cover 12. At this time, through the heat conduction effect of the heat-conducting plate 13, the measuring head 1102 and the space covered by the annular cover 12 can be heated and kept warm, preventing water vapor from condensing on the measuring head 1102 and ensuring the accuracy of the measurement.

[0043] When measurement is not required, energizing the electromagnet 907 attracts the iron block 906, which in turn moves the annular cover 12 upward via the connecting block 901. Simultaneously, the second spring 905 is compressed. During measurement, when the annular cover 12 moves downward, it moves the sealing plate 10 downward synchronously. At the same time, the push pin 804 slides along the spiral groove 801 to the vertical groove 802. This allows the sealing plate 10 to rotate and open along the rotating rod 702, ensuring normal measurement by the measuring head 1102. When measurement is not required, when the annular cover 12 moves upward, the push pin 804 slides along the vertical groove 802 to the spiral groove 801. This allows the sealing plate 10 to rotate and reset along the rotating rod 702, sealing the bottom of the annular cover 12. This protects the measuring head 1102, ensuring its measurement accuracy and service life.
