Description

Technical Field

[0001] The present invention relates to the technical field of flatness detection, and in particular to an intelligent detection terminal and method for the flatness of a functional coating on a structural part. Background Art

[0002] When evaluating product performance through environmental testing, coating aging (particularly the quantification of coating damage) is a key evaluation metric. Currently, there are two primary approaches for monitoring coating aging: one involves regularly capturing the surface morphology of the product coating with a high-definition camera and analyzing any changes in the morphology; the other involves technicians regularly visually observing and recording the surface morphology of the product coating. However, when the depth of a coating bulge or indentation is less than 3 mm, even when viewing the coating directly from the front, the bulge and surrounding areas exhibit a high degree of visual integration, making it difficult to capture these subtle changes. Furthermore, when the product surface exhibits a curved shape, traditional flatness inspection tools often struggle to effectively detect it. Even more challenging, when the coating undergoes significant deformation, these changes are equally difficult to capture with existing monitoring methods.

[0003] In response to the above problems, the present invention document proposes an intelligent detection terminal and method for the flatness of functional coatings on structural parts. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that when the depth of the coating bulge or depression is less than 3 mm, even when looking directly at the coating from the front, the bulge area and the surrounding area still show a high degree of visual integration, which makes it difficult to capture these subtle changes in real time. In addition, if the surface of the product is curved, traditional flatness detection tools are often unable to cope with it and it is difficult to implement effective detection. What is even more troublesome is that when the coating undergoes a large deformation, these changes are also difficult to be captured in time by existing monitoring means. Therefore, an intelligent detection terminal and method for the flatness of functional coatings on structural parts are proposed.

[0006] Preferably, the first metal probe corresponds to the upper and lower positions of the detection roller; The control device is connected to the host device via a connecting line, and a plurality of supporting components are arranged below the control device.

[0007] Preferably, the support assembly includes a threaded sleeve, which is fixedly installed below the control device, and the threaded sleeve is internally threaded with a threaded roller.

[0008] Preferably, the protective component includes a shell, handles are provided on both sides of the shell, an upper cover is fixed to the upper part of the shell by bolts, multiple guide openings are provided below the upper cover and the shell, and the upper cover has two movable openings.

Multiple claws are provided on the upper and lower sides of the movable plate. The claws slide in the guide opening, and the upper claw limits the detection part, and the lower claw limits the model. The detection part is placed on the surface of the upper cover.

[0010] Preferably, the elastic limiting assembly includes two fixed blocks, the detection roller is rotatably mounted on the two fixed blocks through two bearings, a spring and a sliding rod are fixedly connected above the fixed blocks, the top of the spring is fixedly connected to the I-type plate, and the I-type plate slides in the movable opening.

[0011] Preferably, the sliding rod passes through the I-shaped plate and is fixedly connected to the connecting rod. The two connecting rods are fixedly connected to both ends of the two limiting rods, and the positioning frame is set up on the limiting rod.

[0013] Preferably, the pulley is fixedly connected between two connecting members, and the two connecting members are fixedly mounted on the first metal probe and the second metal probe respectively.

[0014] A method for using an intelligent detection terminal for flatness of a functional coating on a structural part comprises the following steps: S1. When testing a test piece with a curved surface, place a corresponding model according to the curved shape of the test piece into the housing, then close the housing with the upper cover to complete the assembly. The test piece is then placed on top of the upper cover. The bidirectional screw is then rotated by the handle. The bidirectional screw drives the two nuts toward each other, bringing the two movable plates closer together. The movable plates then clamp the model and the test piece in place using the clamping jaws. S2. Then, place the control device on the upper cover so that the positioning frame engages with the limiting rod, and the Teflon microsphere contacts the detection element, and the position of the Teflon microsphere corresponds to the position of the detection roller; S3. After the control device is placed, the control device is moved directly or through the connecting rod to move the control device, so that the PTFE microsphere and the detection roller move synchronously. When the detection roller moves to the curved surface of the model, the detection roller drives the sliding rod and the connecting rod to move upward, so that the connecting rod drives the control device to move upward through the limit rod and the positioning frame, so that the PTFE microsphere passes smoothly over the curved surface of the detection part; S4. When a bulge appears on the surface of the test piece, the PTFE microsphere moves to the bulge position and pushes up the first metal probe. The top end of the first metal probe is inserted into the carbon fiber layer, thereby connecting the negative electrode of the power supply with the positive electrode of the power supply. The control device then feeds back the test result signal to the host device for recording. S5. When a concave surface appears on the surface of the detection part, the first metal probe is pulled downward by the gravity of the first weighted ball, causing the first metal probe to pull the metal chain and the second metal probe to move. The second metal probe is also inserted upward into the carbon fiber layer, thereby re-energizing and feeding back a signal to the host device. S6. When the PTFE microsphere is located at the previously detected bulge again, the first metal probe is in the initial state and remains unpowered. At this time, coating peeling occurs at the detection site, and corresponding coating peeling information is output to the host device. S7. When it is necessary to inspect the flat surface of the test piece, the control device is directly placed on the test piece. At this time, the test piece is supported by the roller to maintain the balance of the PTFE microspheres, thereby smoothly carrying out the flatness inspection operation.

[0015] Compared with the prior art, the present invention provides an intelligent detection terminal and method for the flatness of functional coatings on structural parts, which has the following beneficial effects: 1. The intelligent detection terminal and method for the flatness of functional coatings of structural parts move the polytetrafluoroethylene microspheres to the bulge position. At this time, the first metal probe is pushed up and inserted into the carbon fiber layer, thereby connecting the negative pole of the power supply with the positive pole of the power supply, and feeding back the information to the host device. Similarly, when the polytetrafluoroethylene microspheres move to the concave surface, the gravity of the first weighted ball causes the first metal probe to move downward. At this time, the metal chain drives the second metal probe to be inserted into the carbon fiber layer, and power is turned on and recorded again. This method can realize the detection of raised or sunken structures, and can be used for timely and accurate observation of coating bulges, depressions and peeling defects. It has the advantages of low cost, good stability, and easy implementation of monitoring in the process of quantitative assessment and monitoring of coating damage, and improves accuracy.

[0016] 2. The intelligent detection terminal for the flatness of functional coatings of structural parts and the method thereof engage the positioning frame with the limit rod, so that the control device is connected to the detection roller through the elastic limit component. At this time, when the control device is translated for detection, the detection roller rolls synchronously, and the detection roller rolls on a model with the same shape as the detection part. When it moves to the arc surface position of the model, the elastic support component drives the control device and the Teflon microspheres to move up to the same position, so that the Teflon microspheres smoothly transition on the arc surface of the detection part, thereby being applicable to detection operations of different arc surfaces and improving the applicability of detection.

[0017] 3. The intelligent detection terminal and method for the flatness of the functional coating of the structural part are configured to separate and use each Teflon microsphere. When each Teflon microsphere is moved to a local bulge position, a single first metal probe can be inserted into the carbon fiber layer and energized, thereby enabling detection of each local area of the inspection part. When the control device is connected to the elastic limit assembly through the positioning frame, the control device is indirectly connected to the inspection roller, so that the inspection roller and the control device move synchronously. This method can also quickly detect overall deformation of the inspection part, thereby enabling timely and effective detection of defects. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment: by splitting each tetrafluoro microsphere 1035 for use, when each tetrafluoro microsphere 1035 is moved to a local bulge position, a single first metal probe 1036 can be inserted into the carbon fiber layer 10310 and energized, so that each local area of the detection part 300 can be detected. After the control device 103 is connected to the elastic limit assembly 205 through the positioning frame 104, the control device 103 is indirectly connected to the detection roller 203, so that the detection roller 203 and the control device 103 move synchronously. This method can also quickly detect when the detection part 300 is deformed as a whole, so that defects can be detected in a timely and effective manner.

[0028] A method for using an intelligent detection terminal for flatness of a functional coating on a structural part comprises the following steps: S1. When testing a curved inspection member 300, a corresponding model 204 is placed into the housing 2011 according to the curved shape of the inspection member 300. The housing 2011 is then closed with the upper cover 2012 to complete the assembly. The inspection member 300 is then placed on top of the upper cover 2012. The bidirectional screw 2021 is then rotated by the handle 2022. The bidirectional screw 2021 drives the two nuts 2023 toward each other, bringing the two movable plates 2024 toward each other. The movable plates 2024 clamp the model 204 and the inspection member 300 in place using the clamping jaws 2025. S2. Then, the control device 103 is placed on the upper cover 2012 so that the positioning frame 104 engages with the limiting rod 2055 . At the same time, the tetrafluoroethylene microspheres 1035 contact the detection element 300 , and the position of the tetrafluoroethylene microspheres 1035 corresponds to the position of the detection roller 203 . S3. After the control device 103 is placed, the control device 103 is moved directly or through the connecting rod 2056, so that the polytetrafluoroethylene microspheres 1035 and the detection roller 203 move synchronously. When the detection roller 203 moves to the curved surface of the model 204, the detection roller 203 drives the sliding rod 2052 and the connecting rod 2056 to move upward, so that the connecting rod 2056 drives the control device 103 to move upward through the limiting rod 2055 and the positioning frame 104, so that the polytetrafluoroethylene microspheres 1035 smoothly pass over the curved surface of the detection member 300. S4. When a bulge appears on the surface of the detection element 300, the polytetrafluoroethylene microsphere 1035 moves to the bulge position and pushes up the first metal probe 1036. The top end of the first metal probe 1036 is inserted into the carbon fiber layer 10310, thereby connecting the negative electrode of the power supply with the positive electrode of the power supply. The control device 103 then feeds back a detection result signal to the host device 101 for recording. S5. When a concave surface appears on the surface of the detection member 300, the gravity of the first weighted ball 1038 pulls the first metal probe 1036 downward, causing the first metal probe 1036 to pull the metal chain 10311 and the second metal probe 1031 to move. The second metal probe 1031 is also inserted upward into the carbon fiber layer 10310, thereby re-energizing and feeding back a signal to the host device 101. S6. When the tetrafluoroethylene microsphere 1035 is located at the previously detected bulge position again, the first metal probe 1036 is in the initial state and remains unpowered.
