Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane testing technology, specifically a waterproof membrane thickness testing device. Background Technology

[0002] During the design phase of building waterproofing projects, the thickness of the waterproofing membrane is determined based on factors such as the building's function, waterproofing level, and operating environment. For example, underground projects typically have higher waterproofing requirements, and the design may specify the use of a thicker waterproofing membrane to ensure long-term and effective prevention of groundwater seepage. By testing the thickness, it can be ensured that the waterproofing membrane used meets design standards, thereby providing a reliable waterproof barrier for the building.

[0003] Thicker waterproof membranes generally offer better puncture resistance and aging resistance. Over long-term use, they are better able to withstand external damage and the effects of natural environmental factors (such as ultraviolet radiation, temperature changes, and chemical corrosion). Testing the thickness helps ensure the membrane has sufficient durability, extends the lifespan of the waterproofing layer, and reduces the frequency of future repairs and replacements.

[0004] Traditional testing methods involve damaging the outer side of the waterproof membrane. Once damaged, the test results will vary depending on the degree of damage in the testing area. Furthermore, damaging the membrane can easily damage the substrate. Therefore, this application provides a waterproof membrane thickness testing device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a waterproof membrane thickness testing device, solving the significant defects of traditional waterproof membrane thickness testing methods. These methods often require damaging the outer surface of the membrane, and because the degree of damage is difficult to control precisely and varies from method to method, the test results differ greatly, significantly reducing accuracy and reliability.

[0006] The waterproof membrane thickness testing device of this utility model includes a support frame for support, a winding assembly disposed on one side of the support frame, and a detection assembly installed on the winding assembly.

[0007] The winding assembly includes a winding bar and a movable bar. The bottom of the winding bar is provided with a pulley and a drive motor installed at the bottom of the pulley. The drive motor is installed inside the support frame.

[0008] The top and bottom of the movable rod are provided with locking blocks, which are adapted to one side of the support frame;

[0009] A support plate is installed between the movable rod and the winding rod. Limiting rods are provided on both sides of the front of the support plate. A lead screw is provided between the two limiting rods. Lugs are provided at the top and bottom of the lead screw. The lugs are adapted to the top and bottom sides of the support plate. A second drive motor is provided at the bottom of the lead screw for driving the lead screw to rotate.

[0010] A mounting plate is fitted onto the middle of the lead screw, and the mounting plate is adapted to the detection component.

[0011] As a further improvement of this utility model, the inner walls of the mounting plate are sleeved on both sides and the outer sides of the limiting rod, and the drive motor drives the lead screw to reciprocate linearly along the limiting rod seat.

[0012] As a further improvement of this utility model, a second pulley is provided at the bottom of the lead screw, and the second pulley is adapted to the second drive motor.

[0013] As a further improvement of this utility model, a slot is provided on one side of the card block, which is adapted to the end of the movable rod for fixing the movable rod.

[0014] As a further improvement of this utility model, the detection component includes a mating block, one side of which is provided with a planar area, and a slot is provided in the planar area.

[0015] As a further improvement of this utility model, a flaw detector is installed on the inner side of the slot for detecting the target object sleeved between the movable rod and the winding rod.

[0016] As a further improvement of this utility model, a groove is provided in the middle of the mounting plate, which is adapted to the fitting block of the detection component for fixing the detection component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention employs a flaw detector (such as an ultrasonic flaw detector) to inspect waterproof membranes. This flaw detector utilizes the principle of ultrasonic waves propagating in different media and reflecting off interfaces, allowing for accurate thickness measurement without damaging the membrane. This avoids the inaccurate results of traditional testing methods that damage the outer surface of the membrane and are difficult to control in terms of the degree of damage. It can accurately measure the membrane thickness and detect internal defects such as bubbles and cracks, greatly improving the comprehensiveness and accuracy of the inspection.

[0019] The components of the winding and inspection assemblies are ingeniously designed and tightly integrated. Drive motors one and two can be either AC servo motors or high-precision stepper motors, respectively, enabling precise control of the winding speed of the winding rod and the moving speed and position of the mounting plate. This allows the flaw detector to accurately inspect different locations on the waterproof membrane, further ensuring the reliability and stability of the inspection results.

[0020] Thickness testing can be performed without damaging the outer surface of the waterproof membrane, avoiding damage to the membrane substrate caused by traditional testing methods and ensuring the integrity and performance of the membrane. The tested membrane can still be used normally, reducing material waste and lowering construction costs. The movable rod is securely installed on the support frame via locking blocks, and the mounting plate moves smoothly under the constraint of the limit rod. The installation and operation of each component fully considers the protection of the membrane, preventing any additional damage during the testing process. Attached Figure Description

[0031] Please see Figure 1-4 In building waterproofing projects, the quality of waterproof membranes plays a crucial role in the waterproofing effect. During the design phase, professionals will accurately determine the required thickness of the waterproof membrane based on various factors such as the building's function, its waterproofing level, and the specific environment in which it is used. For example, underground construction projects, which are constantly exposed to the pressure and erosion of groundwater, have extremely high waterproofing requirements. Thicker waterproof membranes are typically designed and used to ensure that they can effectively block groundwater penetration for a long period, providing reliable waterproofing protection for the building.

[0032] Thicker waterproof membranes generally have better puncture resistance and aging resistance. In actual use, they can better resist the effects of natural environmental factors such as external damage, ultraviolet radiation, large temperature changes, and chemical corrosion, thus ensuring sufficient durability of the waterproof layer, extending its service life, reducing the frequency of later repairs and replacements, and lowering building maintenance costs.

[0033] However, traditional methods for testing the thickness of waterproof membranes have significant drawbacks. These methods often require damaging the outer side of the membrane, and because the degree of damage is difficult to control precisely and varies from person to person, the test results differ greatly, significantly reducing accuracy and reliability. Moreover, the process of damaging the membrane can easily damage the substrate, affecting not only the integrity and performance of the membrane but also rendering the tested membrane unusable, resulting in material waste. Therefore, the market urgently needs a new type of waterproof membrane thickness testing device to solve the problems of traditional testing methods. Based on this, this application provides a waterproof membrane thickness testing device, including a support frame 1 for support, a winding assembly 2 disposed on one side of the support frame 1, and a testing assembly 3 mounted on the winding assembly 2.

[0034] The winding assembly 2 includes a winding bar 21 and a movable bar 28. The bottom of the winding bar 21 is provided with a pulley 23 and a drive motor 22 installed at the bottom of the pulley 23. The drive motor 22 is installed inside the support frame 1.

[0035] The top and bottom of the movable rod 28 are provided with locking blocks 27, which are adapted to one side of the support frame 1;

[0036] A support plate 212 is installed between the moving rod 28 and the winding rod 21. Limiting rods 29 are provided on both sides of the front of the support plate 212. A lead screw 211 is provided between the two limiting rods 29. Ear blocks 210 are provided at the top and bottom of the lead screw 211. The ear blocks 210 are adapted to the top and bottom sides of the support plate 212. A drive motor 24 is provided at the bottom of the lead screw 211 for driving the lead screw 211 to rotate.

[0037] A mounting plate 26 is fitted in the middle of the lead screw 211, and the mounting plate 26 is adapted to the detection component 3.

[0038] The winding rod 21 is an important component of the winding assembly 2, used for winding the waterproof membrane. A pulley 23 and a drive motor 22 are mounted on the bottom of the pulley 23, with the drive motor 22 installed inside the support frame 1. When the drive motor 22 starts, it drives the pulley 23 to rotate, which in turn drives the winding rod 21 to rotate, thus achieving the winding action of the waterproof membrane. For example, in practical applications, the drive motor 22 can be a servo motor, whose speed can be precisely adjusted according to the required winding speed to ensure the stability and uniformity of the winding process.

[0039] The movable rod 28 has locking blocks 27 at both its top and bottom, which are adapted to one side of the support frame 1. This adaptation design allows the movable rod 28 to be flexibly installed on the support frame 1 and to be disassembled and its position adjusted as needed. A support plate 212 is installed between the movable rod 28 and the winding rod 21, serving as a connection and support.

[0040] Limiting rods 29 are provided on both sides of the front of the support plate 212. These limiting rods 29 restrict the movement range of the mounting plate 26, ensuring more stable movement of the mounting plate 26 on the lead screw 211. A lead screw 211 is positioned between the two limiting rods 29. Lugs 210 are provided at both the top and bottom of the lead screw 211, and these lugs 210 are adapted to the top and bottom sides of the support plate 212. This adaptation ensures that the lead screw 211 can be stably mounted on the support plate 212. A second drive motor 24 is provided at the bottom of the lead screw 211 to drive its rotation. When the second drive motor 24 is started, the lead screw 211 rotates, thereby causing the mounting plate 26, which is sleeved in the middle of the lead screw 211, to move up and down along the lead screw 211. For example, the second drive motor 24 can be a stepper motor, which has precise control performance and can accurately control the rotation angle and speed of the lead screw 211, thus achieving precise movement of the mounting plate 26.

[0041] A mounting plate 26 is fitted onto the middle of the lead screw, and the mounting plate 26 is adapted to the detection component 3. The detection component 3 is mounted on the mounting plate 26. As the mounting plate 26 moves up and down under the drive of the lead screw 211, the thickness of the waterproof membrane at different positions can be detected. The detection component 3 can use a non-contact thickness detection sensor, such as a laser thickness sensor, which can accurately measure the thickness of the waterproof membrane without contact, avoiding damage to the membrane. For example, the measurement accuracy of a laser thickness sensor can reach millimeters, which can meet the needs of most waterproof membrane thickness detection.

[0042] The waterproof membrane is wound up using the winding assembly 2, while the mounting plate 26 and the detection assembly 3 are moved by the lead screw 211, enabling comprehensive and accurate thickness detection of the waterproof membrane. The use of the non-contact detection assembly 3 avoids damage to the membrane, improves the accuracy and reliability of the detection results, and solves the problems associated with traditional detection methods.

[0043] Installation process:

[0044] Install the support frame 1 in a suitable position to ensure its stability and reliability.

[0045] Install the drive motor 22 inside the support frame 1, and then install the pulley 23 at the bottom of the winding bar 21 and connect it to the drive motor 22. Install the winding bar 21 on the support frame 1, ensuring that it can rotate freely.

[0046] The movable bar 28 is installed on one side of the support frame 1 via the locking block 27, so that it corresponds to the winding bar 21.

[0047] Install a support plate 212 between the moving bar 28 and the winding bar 21 to ensure that it is securely installed.

[0048] Install the limiting rods 29 on both sides of the front of the support plate 212, then install the lead screw 211 between the two limiting rods 29 through the lug 210, and install the drive motor 24 at the bottom of the lead screw 211.

[0049] Mounting plate 26 is fitted onto the middle of lead screw 211, and then detection assembly 3 is installed on mounting plate 26.

[0050] Work process

[0051] One end of the waterproof membrane to be tested is fixed to the winding rod 21.

[0052] Start the drive motor 22, which drives the winding rod 21 to rotate and begin winding the waterproof membrane.

[0053] Start the drive motor 24 to drive the lead screw 211 to rotate, so that the mounting plate 26 moves up and down along the lead screw 211, thereby driving the detection component 3 to detect the thickness of the waterproof membrane at different positions.

[0054] The detection component 3 transmits the detected thickness data to the control system for processing and analysis, and finally obtains the thickness detection result of the waterproof membrane.

[0055] The inner walls of the mounting plate 26 are fitted onto the outer sides of the limiting rod 29, and the lead screw 211 is driven by the drive motor 24 to reciprocate linearly along the limiting rod 29.

[0056] The bottom of the lead screw 211 is provided with a pulley 25, which is adapted to the drive motor 24.

[0057] A slot 31 is provided on one side of the locking block 27. The slot 31 is adapted to the end of the movable rod 28 and is used to fix the movable rod 28.

[0058] The winding rod 21 is one of the core components of the winding assembly 2, used for winding the waterproof membrane. It has a pulley 23 at its bottom, and a drive motor 22 is mounted on the bottom of the pulley 23. The drive motor 22 is installed inside the support frame 1. When the drive motor 22 starts, it drives the pulley 23 to rotate, which in turn drives the winding rod 21 to rotate, thus achieving the winding operation of the waterproof membrane. By adjusting the speed of the drive motor 22, the winding speed can be controlled to ensure a smooth and uniform winding process.

[0059] Movable rod 28: Movable rod 28 has locking blocks 27 at both its top and bottom, which are adapted to one side of the support frame 1. A slot 31 is provided on one side of the locking block 27, which is adapted to the end of the movable rod 28. This design allows the movable rod 28 to be securely installed on the support frame 1. When it is necessary to install or remove the movable rod 28, simply align the end of the movable rod 28 with the slot 31 and insert or remove it; the operation is simple and quick. A support plate 212 is installed between the movable rod 28 and the winding rod 21. The support plate 212 serves as a connection and support, providing a stable foundation for the installation of subsequent components.

[0060] Limiting rods 29 are provided on both sides of the front of the support plate 212. The limiting rods 29 limit the range of movement of the mounting plate 26, ensuring that the mounting plate 26 will not deviate from the predetermined track during movement, thereby improving the stability and reliability of the device.

[0061] A lead screw 211 is positioned between the two limiting rods 29. Lugs 210 are provided at both the top and bottom of the lead screw 211, and these lugs 210 are adapted to the top and bottom sides of the support plate 212. This adaptation method ensures that the lead screw 211 is securely mounted on the support plate 212, preventing wobbling or deviation during rotation. A pulley 25 is located at the bottom of the lead screw 211, and this pulley 25 is adapted to a drive motor 24. When the drive motor 24 starts, it drives the pulley 25 to rotate, thereby driving the lead screw 211 to rotate. The drive motor 24 can be a stepper motor, which has precise control performance and can accurately control the rotation angle and speed of the lead screw 211 as needed, thus achieving precise movement of the mounting plate 26.

[0062] A mounting plate 26 is sleeved on the middle of the lead screw 211, and the inner walls of the mounting plate 26 are sleeved on both sides of the limiting rod 29. When the lead screw 211 rotates under the drive of the second drive motor 24, the mounting plate 26 will reciprocate linearly along the limiting rod 29. This design allows the mounting plate 26 to move smoothly and accurately under the drive of the lead screw 211, providing a guarantee for the detection component 3 to detect the thickness of the waterproof membrane at different locations.

[0063] Mounting plate 26 is adapted to detection component 3, which is mounted on mounting plate 26. As mounting plate 26 moves up and down along limit rod 29 driven by lead screw 211, detection component 3 can detect the thickness of waterproof membrane at different locations. Detection component 3 can employ a high-precision non-contact laser thickness sensor, which has advantages such as high measurement accuracy, fast response speed, and insensitivity to the surface material and color of the membrane. During detection, the laser thickness sensor emits a laser beam that irradiates the surface of the waterproof membrane, and the thickness of the membrane is calculated by measuring the laser reflection time, thus avoiding contact and damage to the membrane.

[0064] The waterproof membrane is wound in an orderly manner using the winding assembly 2. The mounting plate 26 and the detection assembly 3 are moved by the lead screw 211, enabling comprehensive and accurate thickness detection of the waterproof membrane. The non-contact detection assembly 3 avoids damage to the membrane, improving the accuracy and reliability of the detection results while ensuring the integrity of the membrane, allowing it to remain usable after testing. Furthermore, the device has a reasonable structural design, is easy to operate, and possesses high practicality and potential for wider application.

[0065] Installation process

[0066] First, install the support frame 1 on a horizontal and stable workbench, ensuring that each support leg of the support frame 1 is in close contact with the workbench surface to guarantee the stability of the entire device.

[0067] Install the drive motor 22 inside the support frame 1 and secure it with bolts to ensure a firm installation. Then, install the pulley 23 at the bottom of the winding bar 21 and connect it to the output shaft of the drive motor 22 via a belt. Adjust the belt tension to ensure stable power transmission. Finally, install the winding bar 21 onto the support frame 1, allowing it to rotate freely.

[0068] Align the end of the movable rod 28 with the slot 31 on the locking block 27, and install the movable rod 28 on one side of the support frame 1, ensuring that the movable rod 28 is parallel to the winding rod 21 and the spacing is appropriate.

[0069] Install a support plate 212 between the movable rod 28 and the winding rod 21, and use bolts to fix the support plate 212 to the movable rod 28 and the winding rod 21 to ensure that the support plate 212 is firmly installed.

[0070] Install the limiting rods 29 on both sides of the front of the support plate 212 and secure them with nuts, ensuring that the limiting rods 29 are installed vertically and firmly. Then, install the lead screw 211 between the two limiting rods 29 via the lugs 210, and adjust the position of the lead screw 211 so that it is parallel to the limiting rods 29. Install the second pulley 25 on the bottom of the lead screw 211 and connect it to the output shaft of the second drive motor 24 via a belt, adjusting the belt tension. Finally, install the second drive motor 24 on the bottom of the support plate 212 and secure it with bolts.

[0071] Mounting plate 26 is fitted onto the middle of lead screw 211, with its inner walls aligned with the outer sides of limit rod 29, ensuring that mounting plate 26 can move smoothly along limit rod 29 under the drive of lead screw 211. Then, detection assembly 3 is installed on mounting plate 26 and secured with bolts to ensure that detection assembly 3 is firmly installed and accurately positioned.

[0072] Work process

[0073] Fix one end of the waterproof membrane to be tested onto the winding rod 21, start the drive motor 22 to drive the winding rod 21 to rotate, and begin winding the waterproof membrane. Adjust the speed of the drive motor 22 according to the specifications of the membrane and the testing requirements to control the winding speed.

[0074] The drive motor 24 is started, driving the lead screw 211 to rotate, causing the mounting plate 26 to reciprocate linearly along the limit rod 29. Simultaneously, the detection component 3 begins to detect the thickness of the waterproof membrane. The detection component 3 transmits the detected thickness data to the control system for processing and analysis.

[0075] During the winding and inspection process, monitor the inspection data and the winding status of the roll material in real time. If abnormal inspection data or uneven winding of the roll material is detected, stop the equipment operation immediately and check and adjust the position and parameters of the relevant components.

[0076] Once the waterproof membrane has been completely rolled up and the inspection is completed, turn off drive motor 22 and drive motor 24, and remove the inspected waterproof membrane.

[0077] The detection component 3 includes a mating block 33, a planar area 32 is provided on one side of the mating block 33, and a slot 31 is provided in the planar area 32.

[0078] A flaw detector is installed on the inside of the slot 31 to inspect the target object that is sleeved between the movable rod 28 and the winding rod 21.

[0079] The mounting plate 26 has a groove in the middle, which is adapted to the mating block 33 of the detection component 3 for fixing the detection component 3.

[0080] Limiting rods 29 are provided on both sides of the front of the support plate 212. The limiting rods 29 limit the range of movement of the mounting plate 26, ensuring that the mounting plate 26 will not deviate from the predetermined track during movement, thereby improving the stability and reliability of the device. The surface of the limiting rods 29 is precision machined and has a high degree of smoothness, which can reduce friction with the mounting plate 26 and make the movement of the mounting plate 26 smoother.

[0081] A lead screw 211 is positioned between the two limiting rods 29. Lugs 210 are provided at both the top and bottom of the lead screw 211, and these lugs 210 are adapted to the top and bottom sides of the support plate 212. This adaptation method ensures that the lead screw 211 is securely mounted on the support plate 212, preventing wobbling or deviation during rotation. A pulley 25 is located at the bottom of the lead screw 211, and this pulley 25 is adapted to a drive motor 24. When the drive motor 24 starts, it drives the pulley 25 to rotate, thereby driving the lead screw 211 to rotate. The drive motor 24 can be a high-precision stepper motor, which has precise control performance and can accurately control the rotation angle and speed of the lead screw 211 as needed, thereby achieving precise movement of the mounting plate 26.

[0082] A mounting plate 26 is sleeved on the middle of the lead screw 211, and the inner walls of the mounting plate 26 are sleeved on both sides of the limiting rod 29. When the lead screw 211 rotates under the drive of the second drive motor 24, the mounting plate 26 will reciprocate linearly along the limiting rod 29. This design allows the mounting plate 26 to move smoothly and accurately under the drive of the lead screw 211, providing a guarantee for the detection component 3 to detect the thickness of the waterproof membrane at different locations.

[0083] The inspection component 3 includes a mating block 33, one side of which has a planar area 32. This planar area 32 is designed to facilitate the installation and positioning of other components. A slot 31 is provided in the planar area 32, and a flaw detector is installed inside the slot 31. The flaw detector can be an ultrasonic flaw detector, which utilizes the principle that ultrasonic waves are reflected when they encounter interfaces in different media to inspect the internal structure and thickness of the waterproof membrane. For example, when ultrasonic waves are injected into the waterproof membrane, reflected waves are generated at the upper and lower surfaces of the membrane. By measuring the time difference and propagation speed of the reflected waves, the thickness of the membrane can be accurately calculated. Simultaneously, the flaw detector can also detect internal defects in the membrane, such as bubbles and cracks, further improving the comprehensiveness and accuracy of the inspection.

[0084] The mounting plate 26 has a groove in its center, which fits into the mating block 33 of the detection component 3. When installing the detection component 3, simply align the mating block 33 with the groove and insert it to achieve a tight connection and fixation between the detection component 3 and the mounting plate 26. This fitting design not only ensures the stability of the detection component 3 installation but also facilitates disassembly and replacement when needed, improving the ease of maintenance of the device. As the mounting plate 26 moves up and down along the limiting rod 29 driven by the lead screw 211, the detection component 3 can detect the thickness of the waterproof membrane at different locations.

[0085] The orderly winding of the waterproof membrane is achieved through the winding assembly 2. The movement of the mounting plate 26 and the detection assembly 3 is driven by the lead screw 211, enabling comprehensive and accurate thickness detection of the waterproof membrane. Using a flaw detector as the detection assembly 3 not only accurately measures the membrane thickness but also detects internal defects, improving the comprehensiveness and reliability of the inspection. Simultaneously, the non-contact detection method avoids damage to the membrane, ensuring its integrity and allowing it to remain usable after inspection. Furthermore, the device has a reasonable structural design, is easy to operate, and possesses high practicality and promotional value.

Use a level to calibrate the device and ensure that the entire device is horizontal to improve the accuracy of the test.

[0088] The drive motor 22 is installed inside the support frame 1 and secured with bolts to ensure a firm installation. Then, the pulley 23 is installed at the bottom of the winding bar 21 and connected to the output shaft of the drive motor 22 via a belt. The belt tension is adjusted to ensure appropriate tension and stable power transmission. Finally, the winding bar 21 is installed on the support frame 1 and connected via bearings to allow it to rotate freely.

[0089] Align the end of the movable rod 28 with the slot 31 on the locking block 27, and install the movable rod 28 on one side of the support frame 1, ensuring that the movable rod 28 is parallel to the winding rod 21 and the spacing is appropriate. Use bolts to further secure the locking block 27 to prevent the movable rod 28 from loosening during use.

[0090] Install a support plate 212 between the movable rod 28 and the winding rod 21. Use bolts to fix the support plate 212 to the movable rod 28 and the winding rod 21 to ensure that the support plate 212 is firmly installed. During the installation process, use a level to check whether the support plate 212 is level. If there is any deviation, adjust it in time.

[0091] Install the limiting rods 29 on both sides of the front of the support plate 212 and secure them with nuts, ensuring that the limiting rods 29 are installed vertically and firmly. After installation, check the parallelism of the limiting rods 29, keeping the error within a very small range to ensure smooth movement of the mounting plate 26. Then, install the lead screw 211 between the two limiting rods 29 via the lug 210, and adjust the position of the lead screw 211 to make it parallel to the limiting rods 29. Install the second pulley 25 on the bottom of the lead screw 211 and connect it to the output shaft of the second drive motor 24 via a belt, adjusting the belt tension. Finally, install the second drive motor 24 on the bottom of the support plate 212 and secure it with bolts.

[0092] Mounting plate 26 is fitted onto the middle of lead screw 211, with its inner walls aligned with the outer sides of limit rod 29, ensuring that mounting plate 26 can move smoothly along limit rod 29 under the drive of lead screw 211. Apply a suitable amount of sealant to the groove of mounting plate 26, then align and insert the mating block 33 of detection component 3 into the groove, gently pressing it to ensure a tight fit between the mating block 33 and the groove, ensuring that detection component 3 is securely installed and accurately positioned.

[0094] One end of the waterproof membrane to be tested is fixed to the winding rod 21. The drive motor 22 is started to drive the winding rod 21 to rotate and begin winding the waterproof membrane. According to the specifications of the membrane and the testing requirements, the speed of the drive motor 22 is adjusted by the controller to control the winding speed, so as to ensure the accuracy and stability of the test.

[0095] The drive motor 24 is started, driving the lead screw 211 to rotate, causing the mounting plate 26 to reciprocate linearly along the limit rod 29. Simultaneously, the flaw detector begins to detect the thickness of the waterproof membrane. The flaw detector emits ultrasonic signals, receives and analyzes the reflected wave signals, and transmits the detected thickness data and defect information to the control system for display and storage.

[0096] During the winding and inspection process, monitor the inspection data and the winding status of the roll material in real time. If abnormal inspection data or uneven winding of the roll material is detected, stop the equipment operation immediately and check and adjust the position and parameters of relevant components. For example, if the thickness deviation of the roll material exceeds the allowable range, it may be due to a quality problem with the roll material itself or a misalignment of the inspection component 3, requiring further inspection and handling.

[0097] After all the waterproof membrane has been rolled up and the inspection is completed, turn off drive motor 22 and drive motor 24, and remove the inspected waterproof membrane. Organize and analyze the inspection data to generate an inspection report, providing a basis for the quality assessment of the waterproof membrane.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
