Description

Technical Field

[0001] This invention relates to a wettability testing device and method for the production of glass fiber cloth. Background Technology

[0002] Fiberglass cloth is a high-performance inorganic non-metallic composite material made from glass fiber as the base material through weaving and surface treatment. It possesses high strength, high temperature resistance, corrosion resistance, fire resistance, and electrical insulation properties, and is widely used in various fields such as building reinforcement, electronic circuits, thermal insulation and waterproofing, and industrial protection. Among these, wettability is a critical core indicator in the production process of fiberglass cloth. Its quality directly determines the interfacial bonding quality between the fiberglass cloth and the resin matrix, thus affecting the mechanical properties, insulation performance, and service life of downstream products. Poor wettability can lead to defects such as voids and delamination between the fiberglass cloth and the resin, significantly reducing the reliability of the final product and even causing product scrapping, resulting in serious economic losses. Therefore, in the large-scale production of fiberglass cloth, rapid, accurate, and efficient testing of its wettability is a key step in ensuring product quality stability, improving production efficiency, and reducing production costs.

[0003] Various methods exist for testing the wettability of fiberglass cloth, including the sinking method, the target method, the adhesive impregnation method, the transmittance method, the lightness factor method of the adhesive sheet, and the solvent penetration method. However, these methods generally have many limitations and are difficult to adapt to the high-efficiency testing requirements of large-scale production. The existing testing devices have unreasonable impregnation treatment structure designs, mostly using a single impregnation tank for impregnation operations, making it difficult to achieve graded impregnation of samples, and easily leading to insufficient and uneven impregnation, which in turn leads to distorted test results. At the same time, most devices lack a real-time monitoring structure for the impregnation process, making it impossible to accurately grasp the impregnation status of the sample. They can only rely on preset impregnation time to determine whether impregnation is complete, and cannot adjust impregnation parameters according to the actual impregnation situation of the sample, further reducing the accuracy and reliability of the test results. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of insufficient and uneven wetting caused by the simple structure of existing wettability testing devices. This invention proposes a wettability testing device for glass fiber cloth production, which sets the wetting treatment components into a first wetting tank and a second wetting tank structure. This enables gradient wetting of the sample from the surface to the interior, effectively avoiding the problems of insufficient and uneven wetting in certain areas, ensuring that the sample reaches a fully wetted state, and providing an accurate basis for subsequent weight collection and data calculation.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a wettability testing device for the production of glass fiber cloth, comprising a frame, a conveyor belt on the frame, and sequentially arranged along the conveying direction on the frame a cutting component for cutting glass fiber cloth into samples, a weighing component for obtaining the initial mass of the cut sample, a wetting treatment component for resin wetting the sample, a collection component for collecting the weight of the sample after resin wetting, and a data processing component for receiving data and performing calculation and analysis on the data. The wetting treatment component includes a first wetting tank for initial wetting of the sample and a second wetting tank for complete wetting of the sample. Both the first and second wetting tanks include a tank body and a monitoring structure disposed within the tank body for real-time monitoring of the sample wetting status.

The wireless measurement module is mounted on the base plate or the frame.

[0009] Preferably, the impregnation treatment assembly further includes a fixing frame, which includes a first vertical rod, a second vertical rod, and a horizontal rod disposed between the first vertical rod and the second vertical rod. The first vertical rod and the second vertical rod are both disposed on the frame.

[0010] Preferably, the monitoring structure includes a light source emitter and a light signal receiver symmetrically arranged on both sides of the tank. Both the light source emitter and the light signal receiver are connected to the data processing component. The light source emitter emits detection light towards the sample, and the light signal receiver receives the intensity of the light signal after penetrating the sample. The data processing component determines the degree of wetting of the sample based on the change in the light signal intensity.

[0011] Preferably, the monitoring structure further includes an indicator light connected to the data processing component. When the data processing component determines that the sample has completed the initial wetting process, or when the sample has reached the fully wetting state, the data processing component sends an action command to the indicator light, which is set on the tank and / or the fixing frame.

[0012] Preferably, the acquisition component includes a frame, a second weighing sensor, and a second weighing tray. The frame is mounted on a rack, and the frame has a groove for mounting the second weighing tray.

[0013] Preferably, the data processing component includes a gateway and a computer, the wireless measurement module is connected to the gateway, the gateway is connected to the computer through a data transmission device, and the rack is equipped with a printer and an alarm, which are respectively connected to the computer.

[0014] In addition, the present invention also provides a wettability testing method for the production of glass fiber cloth, a wettability testing method based on a wettability testing device, wherein the wettability testing device is the aforementioned wettability testing device for the production of glass fiber cloth, and the wettability testing method includes the following steps in sequence:

[0015] Step 1: Cut at least three 100mm×100mm samples from the fiberglass cloth using the cutting assembly, ensuring that the sample surface is free of wrinkles, damage and stains. Then, smoothly transport the samples to the next process station via the conveyor belt, ensuring that the samples do not shift during the transport process.

[0016] Step 2: Weigh the sample cut in Step 1 using a weighing assembly to obtain the initial mass M1 of the sample, and synchronize it to the data processing assembly in real time to complete the data verification, storage and filing. After weighing, the sample is transported to the next process station via a conveyor belt.

[0017] Step 3: Place the sample collected in Step 2 into the first impregnation tank of the impregnation treatment component, ensuring that the sample is completely immersed in the impregnation resin in the first impregnation tank, and start the initial impregnation. At the same time, the monitoring structure in the first impregnation tank is activated synchronously. The impregnation status of the sample is monitored in real time through the monitoring structure. When the data processing component determines that the sample has completed the initial impregnation state, the data processing component records the impregnation time as t1. Finally, take out the impregnated sample and hang it to stand for 20-30 seconds.

[0018] Step 4: Place the sample after the initial impregnation in Step 3 into the second impregnation tank, ensuring that the sample is completely immersed in the impregnation resin in the second impregnation tank, and start the deep impregnation treatment. At the same time, the monitoring structure in the second impregnation tank is activated synchronously. The impregnation status of the sample is monitored in real time through the monitoring structure. When the data processing component determines that the sample has reached the complete impregnation state, the data processing component records the impregnation time as t2. Finally, take out the impregnated sample and hang it to stand for 40-60 seconds.

[0019] Step 5: The sample after impregnation in Step 4 is transported to the collection component station via conveyor belt, and the weight M2 of the sample after resin impregnation is collected and synchronized to the data processing component in real time to complete the data verification, storage and filing.

[0020] Step 6: Calculate the resin wetting amount Δm = M2 - M1 and the resin wetting amount percentage η = Δm / M1 × 100% using the data processing component, and determine the wettability grade of the sample by the resin wetting amount Δm, the resin wetting amount percentage η, and the total wetting time t1 + t2.

[0021] In summary, the advantages of this invention are as follows: The impregnation treatment component is configured as a first impregnation tank and a second impregnation tank. The first impregnation tank initially impregnates the sample surface, quickly expelling air from the sample and impregnating the surface fibers, laying the foundation for deep impregnation. The second impregnation tank performs deep impregnation on the sample after initial impregnation, ensuring that the resin fully penetrates into the fiber gaps within the sample. This achieves gradient impregnation from the surface to the interior, effectively avoiding problems of insufficient or uneven impregnation in certain areas, ensuring the sample reaches a fully impregnated state, and providing data for subsequent weight collection and calculation. Precision is paramount. Both the first and second immersion tanks are equipped with real-time monitoring structures, which are linked to the data processing components. This allows for real-time capture of the sample's immersion state, accurately determining the endpoints of initial and complete immersion. This effectively avoids detection errors caused by mismatches between preset times and the actual immersion state, significantly improving the accuracy of immersion testing. Furthermore, the immersion parameters can be adjusted based on the actual immersion condition of the sample, further enhancing detection accuracy. Secondly, the weighing and data acquisition components are connected to the data processing components, thus relying on… The weighing and data acquisition components accurately acquire the initial mass and post-wetting weight of the sample, providing fundamental and accurate data for wetting rate calculation. This avoids reading and operational errors associated with manual weighing. Simultaneously, the data processing component stores and compares test data from multiple batches, revealing differences in wetting properties between different batches of fiberglass cloth. This provides data support for adjusting production processes and enables efficient use of test data. Finally, the cutting component cuts the fiberglass cloth into uniform-sized samples, ensuring consistent area and weight across all test samples. This allows the test data to more accurately reflect the wetting performance of the fiberglass cloth. Furthermore, the frame is equipped with a conveyor belt, and the cutting, weighing, wetting, data acquisition, and data processing components are sequentially arranged along the conveyor belt's direction. This automated sample transfer completely avoids issues such as contamination, breakage, and displacement caused by manual transfer, ensuring the stability of the testing process, improving the testing cycle, and adapting to the testing pace of large-scale, continuous fiberglass cloth production. This addresses the low efficiency of traditional segmented testing methods, and the overall structure is compact and easy to install. Attached Figure Description

Detailed Implementation Example 1

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a wettability testing device for the production of fiberglass cloth includes a frame 1, on which a conveyor belt 11 is provided. The conveyor belt structure is existing technology and will not be described in detail in this embodiment. Along the conveying direction, the frame 1 is sequentially provided with a cutting component 2 for cutting fiberglass cloth into samples, a weighing component 3 for obtaining the initial mass of the cut sample, a wetting treatment component 4 for resin wetting the sample, a collection component 5 for collecting the weight of the sample after resin wetting, and a data processing component 6 for receiving data and performing calculation and analysis on the data. The wetting treatment component 4 includes a first wetting tank 41 for initial wetting of the sample and a second wetting tank 42 for complete wetting of the sample. Both the first wetting tank 41 and the second wetting tank 42 include a tank body 43 and a monitoring structure 44 disposed in the tank body 43 for real-time monitoring of the sample wetting state. The weighing component 3, the collection component 5, and the monitoring structure 44 are all connected to the data processing component 6.

[0033] The impregnation treatment component 4 is configured as a first impregnation tank 41 and a second impregnation tank 42. The first impregnation tank 41 first achieves preliminary impregnation of the sample surface, quickly expelling air from the sample and impregnating the surface fibers, laying the foundation for deep impregnation. The second impregnation tank 42 performs deep impregnation on the sample after preliminary impregnation, ensuring that the resin fully penetrates into the fiber gaps inside the sample, thereby achieving gradient impregnation from the surface to the interior of the sample. This effectively avoids problems such as insufficient or uneven impregnation in certain areas, ensuring that the sample reaches a fully impregnated state, providing an accurate basis for subsequent weight collection and data calculation. Simultaneously, the first... Both the immersion tank 41 and the second immersion tank 42 are equipped with a real-time monitoring structure 44, which is linked with the data processing component 6. This allows for real-time capture of the sample's immersion state, accurate determination of the initial and complete immersion endpoints, and effective avoidance of detection errors caused by mismatches between the preset time and the actual immersion state of the sample. This significantly improves the accuracy of immersion detection and allows for adjustment of immersion parameters based on the actual immersion condition of the sample, further enhancing detection accuracy. Secondly, the weighing component 3 and the data acquisition component 5 are both connected to the data processing component 6, thus relying on weighing during operation. Component 3 and acquisition component 5 accurately acquire the initial mass and post-wetting weight of the sample, providing the most basic and accurate data for wetting rate calculation. This avoids reading and operational errors associated with manual weighing. Simultaneously, data processing component 6 can store and compare test data from multiple batches, thereby understanding the differences in wetting properties between different batches of fiberglass cloth. This provides data support for adjusting production processes and achieves efficient utilization of test data. Finally, the cutting component 2 cuts the fiberglass cloth into uniformly sized samples, ensuring that the area and weight of all test samples are consistent. The test data more accurately reflects the wetting performance of the fiberglass cloth. In addition, the frame 1 is equipped with a conveyor belt 11, and the cutting component 2, weighing component 3, wetting treatment component 4, data acquisition component 5 and data processing component 6 are arranged sequentially along the conveying direction of the conveyor belt 11. This enables automated sample transfer, completely avoiding problems such as sample contamination, damage and displacement caused by manual transfer, ensuring the stability of the testing process, improving the testing cycle, adapting to the testing rhythm of large-scale and continuous production of fiberglass cloth, solving the pain point of low efficiency of traditional segmented testing, and the overall structure is compact and easy to install.

[0034] The cutting assembly 2 includes a base plate 21, a connecting frame 22, and a cutting blade 23. The base plate 21 is fixedly connected to the frame 1. The connecting frame 22 is disposed at one end of the base plate 21, and a clamping assembly 24 is provided at the other end of the base plate 21. The connecting frame 22 is provided with a first lifting cylinder 25 connected to the cutting blade 23. The base plate 21 is provided with a through hole 26 for the cutting blade 23 to pass through. The cutting assembly 2 is configured with a base plate 21, a connecting frame 22, and a cutting blade 23. Because the connecting frame 22 is provided with a first lifting cylinder 25 connected to the cutting blade 23, the cutting blade 23 can move vertically up and down under the action of the first lifting cylinder 25, ensuring the stability of the cutting direction of the cutting blade 23 and ensuring the quality of the sample cutting. Because the base plate 21 is provided with a through hole 26, when the cutting blade 23 cuts downwards, the excess blade body portion... The cutting blade 23 can pass through the through-hole 26 to enter the area below the substrate 21 without colliding with other components on the substrate 21, thus avoiding damage to the cutting blade 23 or the substrate 21. Moreover, the through-hole 26 can guide the cutting blade 23 to prevent it from shifting during the cutting process, ensuring the dimensional accuracy of the sample. Secondly, the other end of the substrate 21 is provided with a clamping component 24, which can firmly fix the glass fiber cloth to the substrate 21 during cutting, preventing the cloth from shifting or wrinkling during the cutting process. This is especially suitable for thin and easy-to-slip glass fiber cloth, reducing the scrap rate of the sample and improving the cutting efficiency. It will not cause spatial interference to the cutting blade 23. The overall structure is simple, easy to install and disassemble, and convenient for subsequent inspection and maintenance. Furthermore, by changing the model of the cutting blade 23 and the stroke of the cylinder, it can be adapted to the cutting needs of glass fiber cloth of different thicknesses and widths.The pressing assembly 24 includes a bracket 241, a second lifting cylinder 242, and a pressing block 243. The bracket 241 includes a vertical portion 244 and a horizontal portion 245. The horizontal portion 245 is located at the top of the vertical portion 244, and the bottom of the vertical portion 244 has a flange 246 connected to the base plate 21. The second lifting cylinder 242 is located on the horizontal portion 245, and the pressing block 243 is located on the second lifting cylinder 242. The pressing assembly 24 is configured with a structure of bracket 241, second lifting cylinder 242, and pressing block 243. Because the pressing block 243 is located on the second lifting cylinder 242, it can move vertically up and down under the action of the second lifting cylinder 242. The lower pressing position of the pressing block 243... The positioning is precise, allowing for accurate alignment with the area of ​​the fiberglass cloth requiring compression, avoiding compression deviations. Furthermore, the pressure of the pressure block 243 can be adjusted via the stroke of the second lifting cylinder 242, preventing the pressure block 243 from damaging the fiberglass cloth due to excessive pressure. It adapts to the compression requirements of different types of fiberglass cloth. The flange 246 increases the contact area between the bracket 241 and the substrate 21, effectively improving the stability of the bracket 241 installation and preventing shaking during the operation of the second lifting cylinder 242. In this embodiment, the flange 246 and the vertical part 244 are an integral structure, which can improve the installation strength of the entire bracket 241 and reduce the installation process between the flange 246 and the vertical part 244. Moreover, the flange 246 and the substrate 21 are fixedly connected by screws.

[0035] The weighing assembly 3 includes a base plate 31, a drying chamber 32, and a first weighing tray 33. The base plate 31 is mounted on the frame 1, the drying chamber 32 is located at one end of the base plate 31, and the first weighing tray 33 is located at the other end of the base plate 31. A first weighing sensor 34 is mounted on the base plate 31 below the first weighing tray 33. A wireless measurement module 7 connected to the data processing assembly 6 is connected to the first weighing sensor 34. The wireless measurement module 7 is mounted on either the base plate 31 or the frame 1. The drying chamber and the wireless measurement module are existing technologies and will not be described in detail in this embodiment. By configuring the weighing assembly 3 with a structure of a base plate 31, a drying chamber 32, and a first weighing tray 33, the first weighing sensor 34 on the base plate 31 below the first weighing tray 33 can directly sense the weight change of the sample on the first weighing tray 33, reducing the error transmission in intermediate links and improving weighing accuracy. Furthermore, the wireless measurement module 7 can collect the signal output by the first weighing sensor 34 in real time and synchronize it to the data processing component 6, making the acquisition of detection data more efficient and accurate. Moreover, the installation position of the wireless measurement module 7 can be set according to the actual installation environment to meet different installation requirements. In this embodiment, the wireless measurement module 7 is preferentially set on the base plate 31. Secondly, the setting of the drying oven 32 can effectively remove the moisture adsorbed by the sample, so as to unify the initial state of the sample. Finally, the drying oven 32 and the first weighing tray 33 are placed at opposite ends of the base plate 31. The heat of the drying oven 32 will not directly affect the working environment of the weighing sensor, avoiding sensor accuracy drift caused by temperature changes and ensuring data reliability. Moreover, the dried sample can be quickly moved to the first weighing tray 33, reducing the loss or contamination of the sample during the handling process, further ensuring the accuracy of the initial weight data.

[0036] The immersion treatment assembly 4 further includes a fixing frame 45, which includes a first vertical rod 451, a second vertical rod 452, and a horizontal rod 453 disposed between the first vertical rod 451 and the second vertical rod 452. Both the first vertical rod 451 and the second vertical rod 452 are mounted on the frame 1. The first immersion tank 41 is disposed on the first vertical rod 451, and the second immersion tank 42 is disposed on the second vertical rod 452. A third lifting cylinder 454 is mounted on the horizontal rod 453, and a suspension clamp 455 for suspending the sample is mounted on the piston rod of the third lifting cylinder 454. By configuring the fixing frame 45 with the first vertical rod 451, the second vertical rod 452, and the horizontal rod 453, the overall structure is simple and allows for the independent installation of the first immersion tank 41 and the second immersion tank 42 on the fixing frame 45. This ensures that the sample can be easily picked up and placed without... While it may be subject to interference, it also ensures the stability of the entire fixed frame 45 on the frame 1. The setting of the suspension clamp 455 ensures that the sample can be accurately and stably immersed in the wetting liquid, avoiding the sample tilting or wrinkling from affecting the wetting effect. Since the suspension clamp 455 is set on the third lifting cylinder 454, the height of the suspension clamp 455 can be adjusted by the extension and retraction of the piston rod of the third lifting cylinder 454 to meet the wetting requirements of different samples. In addition, the suspension clamp 455 facilitates the static suspension of the sample, making it easy to remove excess wetting liquid from the sample surface and ensuring that the wetting liquid can flow back into the tank 43. In this embodiment, at least three suspension clamps 455 are provided to ensure the stable suspension of the sample. A connecting rod can be provided on the piston rod of the third lifting cylinder 454, and the suspension clamp 455 is set on the pull rod.

[0037] The monitoring structure 44 includes a light source emitter 441 and a light signal receiver 442 symmetrically arranged on both sides of the tank 43. Both the light source emitter 441 and the light signal receiver 442 are connected to the data processing component 6. The light source emitter 441 emits detection light towards the sample, and the light signal receiver 442 receives the intensity of the light signal after penetrating the sample. The data processing component 6 determines the degree of wetting of the sample based on the change in light signal intensity. By configuring the monitoring structure 44 with the light source emitter 441 and the light signal receiver 442 symmetrically arranged on both sides of the tank 43, the changes in light signal intensity of the sample during the wetting process can be monitored in real time, thereby determining the degree of wetting in real time. Furthermore, it can monitor the entire wetting process, including the initiation, development, and saturation stages. Continuous monitoring provides complete data for the kinetic analysis of the immersion process, and provides data support for subsequent process optimization and material development. In addition, since the light source emitter 441 and the light signal receiver 442 are symmetrically arranged on both sides of the tank 43, the interference of external light can be reduced during the monitoring process, improving the detection accuracy. Secondly, the entire monitoring process does not require direct contact with the sample, and will not physically interfere with the sample's immersion process, preserving the original immersion state of the sample to the greatest extent, and the detection results are more in line with the real situation. Finally, the whole structure is simple, easy to install and disassemble, and has low subsequent maintenance costs. It can be adapted to various types of immersion test scenarios. The light source emitter 441 and the light signal receiver in this embodiment are existing technologies, and will not be described in detail in this embodiment. The monitoring structure 44 also includes an indicator light 443 connected to the data processing component 6. When the data processing component 6 determines that the sample has completed the initial wetting or the sample has reached the complete wetting state, the data processing component 6 sends an action command to the indicator light 443. The indicator light 443 is set on the tank 43 and / or the fixing frame 45. The setting of the indicator light 443, through different colors or flashing patterns, enables the entire monitoring structure 44 to display different states in real time according to the sample wetting degree, providing intuitive operation guidance for operators and intuitively displaying the sample wetting state, such as initial wetting and complete wetting. Moreover, according to the indication of the indicator light 443, the wetting process parameters, such as wetting time and temperature, can be adjusted in a timely manner to reduce the generation of defective products and reduce production costs. In addition, setting the indicator light 443 on the tank 43 and / or the fixing frame 45 allows for different installation positions to be set according to different needs, meeting different installation requirements. In this embodiment, the indicator light 443 is preferably set on the outer wall of the tank 43.

The second weighing sensor 52 is located at the bottom of the groove 54 and is connected to the wireless measurement module 7. A protective cover 55 is provided on the outer wall of the frame 51 and is detachably mounted on the frame 51. By configuring the data acquisition component 5 as a frame 51, a second weighing sensor 52, and a second weighing tray 53, the stability of the entire data acquisition component 5 is ensured because the frame 51 is mounted on the frame 1. The second weighing sensor 52 is located at the bottom of the groove 54 in the frame 51, and the second weighing tray 53 is installed within the groove 54, thus enabling... The close contact between the second weighing tray 53 and the second weighing sensor 52 not only ensures the accuracy of weighing but also ensures high precision, providing a guarantee for accurately assessing the wettability of the fiberglass cloth. The wireless measurement module 7 can transmit the data from the second weighing sensor 52 to the data processing component 6 in real time, ensuring stable and reliable data transmission. The protective cover 55 prevents dust, oil, or water droplets from entering the acquisition component 5, effectively protecting the second weighing sensor 52 and the second weighing tray 53, extending the service life of the entire acquisition component 5, and without interfering with the acquisition results. In addition, the protective cover 55 is designed as a detachable installation structure, which facilitates subsequent cleaning and maintenance. In this embodiment, the protective cover 55 is installed on the frame 51 by screws, which make the installation and disassembly of the whole assembly convenient and the connection reliable. The data processing component 6 includes a gateway 61 and a computer 62. The wireless measurement module 7 is connected to the gateway 61, and the gateway 61 is connected to the computer 62 via a data transmission device 8. The rack 1 is equipped with a printer 63 and an alarm 64, both connected to the computer 62. By configuring the data processing component 6 with a gateway 61 and a computer 62, the gateway 61 can receive data collected by the wireless measurement module 7 in real time and transmit it to the computer 62 via the data transmission device 8, ensuring the stability of data transmission. The computer 62 can automatically calculate and analyze the data, ensuring the accuracy and reliability of the test results. It can also store the data for automated management. The printer 63 enables the immediate output of test reports. In this embodiment, the alarm is an audible and visual alarm, providing both visual and auditory alerts to adapt to different working environments. Example 2

The wettability testing device is the wettability testing device for glass fiber cloth production described in Embodiment 1. The wettability testing method includes the following steps in sequence:

[0040] Step 1: Cut at least three 100mm×100mm samples from the fiberglass cloth using the cutting assembly 2, ensuring that the sample surface is free of wrinkles, damage and stains. Then, transport the samples smoothly to the next process station via the conveyor belt 11, ensuring that the samples do not shift during the transport process.

[0041] Step 2: Weigh the sample cut in Step 1 through the weighing component 3 to obtain the initial mass M1 of the sample, and synchronize it to the data processing component 6 in real time to complete the data verification, storage and filing. After weighing, the sample is transferred to the next process station through the conveyor belt 11.

[0042] Step 3: Place the sample collected in Step 2 into the first impregnation tank 41 of the impregnation treatment component 4, ensuring that the sample is completely immersed in the impregnation resin in the first impregnation tank 41, and start the initial impregnation. At the same time, the monitoring structure 44 in the first impregnation tank 41 is activated synchronously. The impregnation status of the sample is monitored in real time through the monitoring structure 44. When the data processing component 6 determines that the sample has completed the initial impregnation state, the data processing component 6 records the impregnation time as t1. Finally, take out the impregnated sample and hang it to stand for 20-30 seconds.

[0043] Step 4: Place the sample after the initial impregnation in Step 3 into the second impregnation tank 42, ensuring that the sample is completely submerged in the impregnation resin in the second impregnation tank 42, and start the deep impregnation treatment. At the same time, the monitoring structure 44 in the second impregnation tank 42 is activated synchronously. The impregnation status of the sample is monitored in real time through the monitoring structure 44. When the data processing component 6 determines that the sample has reached the complete impregnation state, the data processing component 6 records the impregnation time as t2. Finally, take out the impregnated sample and hang it to stand for 40-60 seconds.

[0044] Step 5: The sample after impregnation in Step 4 is transported to the collection component 5 station via conveyor belt 11 to collect the weight M2 of the sample after resin impregnation and synchronize it to the data processing component 6 in real time to complete the data verification, storage and filing.

[0045] Step 6: Calculate the resin impregnation amount Δm=M2-M1 and the resin impregnation amount percentage η=Δm / M1×100% using data processing component 6, and determine the wettability level of the glass fiber cloth by using the resin impregnation amount Δm, the resin impregnation amount percentage η and the total impregnation time t1+t2.

[0046] The wettability of fiberglass cloth is tested sequentially through standardized sample preparation, obtaining the initial weight of the sample, preliminary wetting, deep wetting, obtaining the weight of the sample after wetting, and data calculation and judgment. Since step six uses resin wetting amount Δm, resin wetting percentage η, and total wetting time t1+t2 to determine the wettability level of the fiberglass cloth, it can more comprehensively and accurately determine the wettability level, clearly distinguishing between four levels: excellent, good, qualified, and unqualified. This clarifies the production application scenarios corresponding to different levels, providing a clear basis for quality control in the production process. Production parameters can be quickly adjusted based on the judgment results to screen qualified products and rework unqualified products, improving the stability of fiberglass cloth product quality and meeting the needs of different downstream products. Furthermore, in step one, cutting at least three 100mm×100mm samples using a cutting component effectively avoids testing with a single sample. To mitigate the randomness of the test results, subsequent calculations using the average of multiple data sets reduce detection errors and improve the reliability of the test results. Furthermore, the absence of wrinkles, damage, and stains on the cut sample surface improves sample quality, preventing data distortion caused by surface contamination and enhancing sample standardization. The initial sample mass M1 obtained in step two and the post-immersion mass M2 collected in step five are synchronized in real-time to the data processing component for verification, storage, and filing, ensuring the integrity and traceability of the test data. This facilitates tracing quality issues and optimizing production parameters during subsequent production. In step three, suspending the immersed sample for 20-30 seconds precisely removes the resin solution from the sample surface, reducing resin waste. In step four, suspending the immersed sample for 40-60 seconds precisely removes the resin solution from the sample surface, preventing the resin solution from affecting the weighing accuracy of M2 and further ensuring the accuracy of the test data.

[0047] In this embodiment, the wettability grade of the fiberglass cloth includes excellent, good, qualified, and unqualified, as shown in Table 1:

[0048] As shown in Table 1, the grade descriptions are as follows: Excellent grade indicates extremely good wetting effect; the sample is completely wetted without any dead spots, exhibiting excellent adhesion to the resin, meeting the production requirements of high-end products such as high-end copper-clad laminates and precision composite materials. Good grade indicates good wetting effect; the sample has no obvious unwetted areas, exhibiting good adhesion to the resin, meeting the production requirements of mid-range products such as conventional composite materials and building materials. Acceptable grade indicates acceptable wetting effect; the sample has only a small amount of unwetted areas at the edges, and the adhesion to the resin meets basic usage requirements, suitable for low-end products such as low-requirement building materials and ordinary insulating parts. Unacceptable grade indicates poor wetting effect; the sample has large unwetted areas, exhibiting poor adhesion to the resin, failing to meet production requirements, and requiring rework. Judgment is based on all three parameters meeting the corresponding grade requirements; if parameters overlap, the lowest grade prevails.

[0049] In addition to the preferred embodiments described above, there are other embodiments of the present invention. Those skilled in the art can make various changes and modifications based on the present invention, and all such changes and modifications should fall within the scope defined by the appended claims, as long as they do not depart from the spirit of the present invention.
