Description

Technical Field

[0001] This invention relates to the field of fiberglass cloth defect detection technology, specifically to a fiberglass cloth defect detection method and apparatus based on AI vision. Background Technology

[0002] Fiberglass cloth, or simply fiberglass cloth, is a substrate woven from extremely fine glass fibers. It is one of the core raw materials for manufacturing printed circuit boards. Its final quality and reliability depend to a large extent on the quality of its substrate, namely the fiberglass cloth. Therefore, the detection of defects in fiberglass cloth is a crucial quality checkpoint. Common methods for detecting defects in fiberglass cloth involve using optical means in conjunction with AI vision inspection. AI vision-based fiberglass cloth defect detection is an automated inspection device that integrates machine vision and artificial intelligence technologies, which can improve the quality of fiberglass cloth inspection. The defect detection device for fiberglass cloth based on AI vision requires optical illumination followed by processing by an internal module. This process can be affected by strong ambient light, which can cause unstable signal reception by the internal signal receiving components, thus affecting the detection results. Furthermore, the device may be affected by wrinkles caused by incomplete stretching of the fiberglass cloth during the detection process, which can also affect the accuracy of the detection.

[0003] To address the aforementioned issues, we propose an AI-based vision-based defect detection device for fiberglass cloth. Summary of the Invention

This solves the problems of traditional devices lacking leveling and protection against the influence of other light sources during the detection process, ensuring the accuracy of the device during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fiberglass cloth defect detection device based on AI vision, comprising a detection box, a detection component for detection is provided on one side of the lower inner wall of the detection box, and a conveyor belt for conveying is embedded on the lower side of the inner wall of the detection box to the left of the detection component.

[0006] Furthermore, the guide assembly includes a connecting groove fixedly installed on the lower side of the inner wall of the detection box, and a connecting block for connection is fixedly installed on the inner wall of the connecting groove by bolts. A first connecting frame is fixedly installed on the side of the connecting block away from the connecting groove, and a sliding groove for sliding is opened on the opposite side of the inner wall of the first connecting frame. A slider is fixedly installed on the upper side of the inner wall of the two sliding grooves by two damping springs. A pressing roller for pressing is rotatably installed on the opposite sides of the two corresponding sliders.

[0007] Furthermore, the leveling assembly includes a fixed vertical block fixedly installed on the lower side of the inner wall of the detection box, and two support hole blocks for support are fixedly installed on the side of the fixed vertical block near the conveyor belt. An N-type push rod for pushing is slidably installed on the inner wall of the two support hole blocks, and a second connecting frame is fixedly installed on the lower end of the N-type push rod. Springs for elastic pushing are sleeved on both opposite sides of the N-type push rod above the support hole blocks. On opposite sides of the inner wall of the second connecting frame, electric rollers for power transmission are fixedly installed. A pulling roller for pulling is fitted onto the surface of the electric roller, and the pulling roller contains several locking components for locking and limiting. On opposite sides of the inner wall of the detection box, two support blocks for support are fixedly installed. Reinforcing plates for reinforcement are fixedly installed on opposite sides of the two corresponding support blocks. Connecting shafts are fixedly installed on opposite sides of the two corresponding support blocks on one side of the reinforcing plates. A pressing and actuating plate for squeezing and actuating is rotatably installed on opposite sides of the two corresponding connecting shafts. A rotary spring is fixedly installed on the surface of the connecting shaft, and one end of the rotary spring is fixedly connected to the surface of the actuating plate. Shock-absorbing rubber blocks for vibration damping are fixedly installed on the top surfaces of the two reinforcing plates, and the top surface of the shock-absorbing rubber blocks contacts the bottom surface of the actuating plate.

[0008] Furthermore, the snap-fit ​​assembly includes a push groove formed on one side of the inner wall of the pull roller. A top block is fixedly installed on the side of the inner wall of the push groove away from the electric roller by a fixed micro damping spring. An arc-shaped top rod for pressing is fixedly installed on the side of the top block close to the electric roller, and an embedding groove is formed on the surface of the electric roller on the side of the arc-shaped top rod.

[0009] Furthermore, the conveyor belt is located at the center of the lower side of the inner wall of the detection box, the two leveling components are located directly below the detection components, and the several guide components are arranged symmetrically from left to right, and the guide components are inclined relative to the conveyor belt.

[0010] Furthermore, both of the protective arc plates are U-shaped plates made of PVC plastic, and the bottom of the protective arc plate has an arc-shaped warp that protrudes downwards.

[0011] Furthermore, the surfaces of several sliders are in close contact with the inner walls of the corresponding sliding grooves, and the bottom surfaces of several extrusion rollers are in contact with the surface of the conveyor belt.

[0012] Furthermore, the vertical cross-section of several of the supporting hole blocks is trapezoidal, the surface of several of the top blocks is in close contact with the inner wall of the pushing groove, and the inner wall of several of the embedding grooves is in contact with the surface of the corresponding arc-head push rod.

[0013] The method for detecting defects in fiberglass cloth based on AI vision includes the following steps; Step 1: Fabric conveying. The fabric conveying involves placing the fabric to be tested under several guide components, and then moving the fabric to be tested under the testing components through the conveyor belt and guide components, thus completing the fabric conveying. Step 2, Fabric Inspection: The fabric inspection is performed by stopping the conveyor belt when the fabric is delivered to the inspection component, and then conducting the fabric inspection through the cooperation of the flattening component and the inspection component.

[0014] In step two, the flattening component and the detection component work together to transport the fabric to be tested to the area below the intelligent vision inspection head via a conveyor belt. Then, driven by the electric slide rail, the intelligent vision inspection head moves downward. During the downward movement of the intelligent vision inspection head, the protective arc plate will squeeze the actuating plate to rotate around the connecting shaft. During the rotation of the actuating plate, it will squeeze the N-type push rod to move downward. At this time, the N-type push rod will drive the second connecting frame to move downward. During the downward movement of the second connecting frame, the pulling roller on the electric roller will first contact the fabric to be tested. Then, through the rotation and locking of the electric roller and the locking component, the pulling roller can rotate. The rotation of the pulling roller ensures the flattening effect of the tested fabric. Under the continuous downward pressure of the actuating plate, the friction between the pulling roller and the conveyor belt will be higher than the pushing force of the micro damping spring in the locking component. At this time, the pulling roller is stationary, and the electric roller is idling, thus ending the pulling effect on the fabric. In this way, the intelligent vision inspection head begins to detect defects in the fabric. After the inspection is completed, the electric slide rail drives the intelligent vision inspection head to move upward. Under the elastic force of the spring and the rotation of the return spring, the pull roller is lifted upward, and the actuating plate will reset and contact the shock-absorbing rubber block on the reinforcing plate. After the fabric inspection is completed, the fabric is transported to one side by the conveyor belt, thus ending the entire fabric inspection process.

[0015] Compared with existing technologies, the present invention provides a method and apparatus for detecting defects in fiberglass cloth based on AI vision, which has the following beneficial effects: 1. This device can flatten the fiberglass cloth during the testing process, avoiding surface wrinkles caused by the fiberglass cloth not being fully stretched, thus ensuring the accuracy of the device's testing. In addition, the device has a protective structure to protect the testing end during the testing process, preventing light sources from other equipment from affecting the signal reception of the testing device, thereby ensuring the normal operation of the device.

[0016] 2. The device utilizes the centered setting of the conveyor belt to ensure the quality of fabric conveying and avoid deviation during the fabric conveying process. The flattening component is located below the detection component, which ensures that the detection component can better detect fabric defects and increase the detection accuracy of the device.

[0017] 3. The device uses an inclined guide component to perform preliminary stretching and flattening of the fabric, which facilitates better flattening of the fabric in the later stage. The material of the protective arc plate and the warping at the bottom can better ensure the squeezing and rotation of the actuating plate and ensure the normal operation of the internal structure of the device.

[0018] 4. This device utilizes the interlocking of the arc-head top rod and the embedded groove to ensure the normal rotation of the electric roller and the pull roller. When the extrusion pressure exceeds the interlocking force of the arc-head top rod and the embedded groove, the electric roller and the pull roller will disengage, thereby ensuring the stability of the fabric detection.

The inner wall of the several embedding grooves 605 is in contact with the surface of the corresponding arc-shaped push rod 604.

[0026] The method for detecting defects in fiberglass cloth based on AI vision includes the following steps; Step 1: Fabric conveying. Fabric conveying involves placing the fabric to be tested under several guide components 4, and then moving the fabric to be tested under the detection component 2 through the conveyor belt 3 and the guide components 4, thus completing the fabric conveying. Step 2, Fabric Inspection: When the fabric is delivered to the inspection component 2, the conveyor belt 3 stops, and then the flattening component 5 and the inspection component 2 work together to inspect the fabric.

[0027] In step two, the leveling component 5 and the detection component 2 work together to transport the fabric to be tested to below the intelligent vision inspection head 202 via the conveyor belt 3. Then, driven by the electric slide rail 7, the intelligent vision inspection head 202 moves downwards. During this downward movement, the protective arc plate 204 presses the actuating plate 511 to rotate around the connecting shaft 510. As the actuating plate 511 rotates, it presses the N-type push rod 503 downwards. At this time, the N-type push rod 503 drives the second connecting frame 504 downwards. During the movement, the pull roller 507 on the electric roller 506 will first contact the fabric to be tested. Then, through the rotation and locking of the electric roller 506 and the locking component 6, the pull roller 507 can rotate. The rotation of the pull roller 507 can ensure the pulling and leveling effect of the tested fabric. Under the continuous pressure of the actuating plate 511, the friction between the pull roller 507 and the conveyor belt 3 will be higher than the pushing force of the miniature damping spring 602 in the locking component 6. At this time, the pull roller 507 is stationary and the electric roller 506 is idling, thus ending the pulling effect on the fabric. The intelligent vision inspection head 202 then begins to inspect the fabric for defects. After inspection, the electric slide rail 7 moves the intelligent vision inspection head 202 upward. Under the elastic force of the spring 505 and the rotation of the return spring 512, the pull roller 507 is lifted upward, and the actuating plate 511 resets and contacts the shock-absorbing rubber block 513 on the reinforcing plate 509. After the fabric inspection is completed, the fabric is conveyed to one side by the conveyor belt 3, thus ending the entire fabric inspection process. The working principle of the above embodiments is as follows: Before the device is installed, the fabric to be tested needs to be placed under several guide components 4. Then, the fabric to be tested is moved towards the detection component 2 by the conveyor belt 3 and the guide components 4. The guide components 4 will push the extrusion roller 407 on the slider 406 to better fit the fabric to be tested through the elastic force of the damping spring 405. This facilitates the normal conveying of the fabric with the conveyor belt 3. In addition, the guide components 4 are set at an angle. This angled guide components 4 can generate a certain lateral tension, which has a preliminary improvement effect on slight wrinkles and facilitates better flattening of the fabric in the later stage, ensuring the accuracy of the detection process. When the fabric is conveyed to the detection component 2, the conveyor belt 3 stops. Then, the flattening component 5 and the detection component 2 work together to detect the fabric. The fabric to be tested is conveyed to the area below the intelligent vision inspection head 202. Then, driven by the electric slide rail 7, the intelligent vision inspection head 202 moves downwards. During this downward movement, the protective arc plate 204 presses against the actuating plate 511, causing it to rotate around the connecting shaft 510. The protective arc plate 204 not only flattens the fabric in conjunction with the detection, but also, due to its U-shaped structure, protects the detection end of the intelligent vision inspection head 202, preventing other light sources from affecting the signal during the detection process. During the rotation of the actuating plate 511, it presses against N... When the N-type push rod 503 moves downward, it will drive the second connecting frame 504 to move downward. During the downward movement of the second connecting frame 504, the pulling roller 507 on the electric roller 506 will first contact the fabric to be tested. Then, through the rotation and locking of the electric roller 506 and the locking assembly 6, the pulling roller 507 can rotate. The rotation of the pulling roller 507 can ensure the pulling and leveling effect of the tested fabric. Under the continuous downward pressure of the actuating plate 511, the friction between the pulling roller 507 and the conveyor belt 3 will be higher than the pushing force of the micro damping spring 602 in the locking assembly 6. At this time, the pulling roller 507 is stationary and the electric roller 506 is idling, thus ending the pulling effect on the fabric. In this way, the intelligent vision inspection head 202 begins to detect defects in the fabric. After the inspection is completed, the electric slide rail 7 drives the intelligent vision inspection head 202 to move upward. Under the elastic force of the spring 505 and the rotation of the return spring 512, the pull roller 507 is lifted upward, and the actuating plate 511 will reset and contact the shock-absorbing rubber block 513 on the reinforcing plate 509. After the fabric inspection is completed, the fabric is conveyed to one side by the conveyor belt 3, thus ending the entire fabric inspection process. The intelligent vision inspection head 202 in this device has the effect of AI control and can transmit the inspection data to the display screen 203 in real time. This technology is existing and mature. This application highlights the innovative structure and does not elaborate on the existing technology. The device performs inspection after the fabric is flattened to avoid the vibration during the flattening process from affecting the accuracy of the inspection.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

The method for detecting defects in fiberglass cloth based on AI vision according to claim 9, characterized in that: In step two, the flattening component (5) and the detection component (2) work together to transport the fabric to be tested to the underside of the intelligent vision inspection head (202) via the conveyor belt (3). Then, driven by the electric slide rail (7), the intelligent vision inspection head (202) moves downward. During the downward movement of the intelligent vision inspection head (202), the protective arc plate (204) will squeeze the actuating plate (511) to rotate around the connecting shaft (510). During the rotation of the actuating plate (511), it will squeeze the N-type push rod (503) to move downward. At this time, the N-type push rod (503) will drive the second connecting frame (504) to move downward. During the downward movement, the pull roller (507) on the electric roller (506) will first contact the fabric to be tested. Then, through the rotation and locking of the electric roller (506) and the locking assembly (6), the pull roller (507) can be rotated. The rotation of the pull roller (507) can ensure the pulling and leveling effect of the fabric to be tested. Under the continuous pressure of the actuating plate (511), the friction between the pull roller (507) and the conveyor belt (3) will be higher than the pushing force of the micro damping spring (602) in the locking assembly (6). At this time, the pull roller (507) is stationary and the electric roller (506) is idling, thus ending the pulling effect on the fabric. In this way, the intelligent vision inspection head (202) begins to inspect the fabric for defects. After the inspection is completed, the electric slide rail (7) drives the intelligent vision inspection head (202) to move upward. Under the elastic force of the spring (505) and the rotation of the rotary spring (512), the pull roller (507) is lifted upward, and the actuating plate (511) will reset and contact the shock-absorbing rubber block (513) on the reinforcing plate (509). After the fabric inspection is completed, the fabric is conveyed to one side by the conveyor belt (3), thus ending the entire process of fabric inspection.
