Its core function is to serve as the basic substrate of printed circuit board (PCB) to provide conductive path, mechanical support and insulation for circuit.
[0003] Traditional equipment often relies on fixed baffles for correcting the alignment of copper clad laminates. However, fixed baffles cannot be adapted to copper clad laminates of different widths. When changing specifications, the machine needs to be stopped to remove the baffles, resulting in poor adaptability and increased downtime. Utility Model Content

[0010] As a further embodiment of this utility model: the bidirectional screw is fixed to the output end of the motor, and the bidirectional screw passes through and is rotatably connected to the inner wall of the intermediate block. The slider is connected to the outer wall of the bidirectional screw by a thread, and the threads at both ends of the bidirectional screw are in opposite directions.
[0011] As a further embodiment of this utility model: the sorting mechanism includes a connecting box, an electric push rod, a crank, a connecting rod, a lever, an extension plate, a drive rod, a gear and a rack, and the connecting box is fixed to the top of the base plate, the electric push rod is installed on one side of the connecting box, and the telescopic end of the electric push rod passes through one side of the connecting box.
[0012] As a further embodiment of this utility model: the crank is rotatably connected to the top of the connecting box, the connecting rod is rotatably connected to the top of the crank, the extension plate is fixed to one side of the connecting box, the lever is rotatably connected to the top of the extension plate, and the connecting rod and the lever are rotatably connected.
[0013] As a further embodiment of this utility model: the drive rod is fixed to the bottom of the crank, the gear is installed at the bottom of the drive rod, the rack is fixed to the output end of the electric push rod, and the rack meshes with the gear. The electric push rod and the intelligent AI control module are electrically connected.
[0014] Compared with the prior art, this utility model provides an AI detection and sorting machine for surface defects of copper-clad laminates, which has the following beneficial effects:
[0015] 1. The copper-clad laminate (CCL) is placed on a conveyor belt. An external drive source rotates the rollers, which in turn drive the conveyor belt, moving the CCL. The CCL first passes through a web-aligning mechanism, which adjusts it to the centerline of the conveyor belt. After alignment, the front end of the CCL passes through a photoelectric sensor on the top of an L-shaped board. The sensor sends a signal to the intelligent AI control module, triggering an industrial camera at the bottom of the L-shaped board to capture a high-definition image of the CCL surface. The industrial camera transmits the image data to the intelligent AI control module, which runs a defect detection algorithm to analyze and determine if the CCL has any defects, and generates... The system determines whether the copper-clad laminate is qualified or unqualified. If it is qualified, the sorting mechanism remains inactive, and the copper-clad laminate continues to be conveyed along the conveyor belt. If it is unqualified, the intelligent AI control module controls the sorting mechanism to push the unqualified copper-clad laminate away from the conveyor belt to the waste area, thus completing the sorting. In this way, the correction mechanism can correct the position of the copper-clad laminate on the conveyor belt, prevent the copper-clad laminate from shifting, and ensure the integrity of the image when the industrial camera is captured. At the same time, it can be adjusted according to the width of the copper-clad laminate, thereby reducing downtime and improving adaptability. Furthermore, the sorting mechanism, in conjunction with the intelligent AI control module, can sort the copper-clad laminate.
[0016] 2. When it is necessary to change to a copper-clad board of different widths, start the motor. Its output end drives the bidirectional screw to rotate. The sliders on both sides are threadedly connected to the bidirectional screw. Under the constraint of the slide rail, they move synchronously in opposite directions along the slide rail, driving the bracket and the correction box to move. Finally, the distance between the two pulleys is adjusted. The two pulleys and the correction box form a guide channel with a wide entrance and a narrow exit. If the board is offset to the left or right, its edge will contact one of the pulleys. The pulley applies lateral force through rotational friction, gradually pushing the board towards the center line of the channel and into the subsequent detection area. Thus, the distance between the pulleys can be quickly adjusted by the motor. At the same time, the pulleys can correct the offset and avoid scratching the surface of the copper-clad board.
[0017] 3. When the intelligent AI control module determines that the copper-clad laminate is unqualified, it sends a retraction signal to the electric push rod. The electric push rod retracts, causing the rack to move horizontally and the gear to rotate. This, in turn, drives the crank to rotate around the top of the connecting box via the drive rod. The crank pushes the lever through the connecting rod, causing the lever to rotate around the top of the extension plate. Its end contacts the edge of the unqualified copper-clad laminate, pushing it away from the conveyor belt to the waste area. When the electric push rod is fully retracted, the rack drives the gear to rotate half a turn. At this point, the lever can just push the copper-clad laminate out. Conversely, when the electric push rod extends, it drives the gear to reverse through the rack. At this point, the lever returns to its original position and becomes parallel to the conveyor belt. Thus, in conjunction with the signal from the intelligent AI control module, qualified and unqualified products can be separated, thereby ensuring the quality of the shipped products.
[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] An AI-based inspection and sorting machine for surface defects in copper-clad laminates, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes a base plate 1, an L-shaped plate 2 fixedly connected to the top of the base plate 1, a connecting seat 7 installed on the top of the base plate 1, rollers 5 rotatably connected to both sides of the inner wall of the connecting seat 7, a conveyor belt 3 sleeved on the outer wall of the rollers 5, a sorting mechanism 6 and a correction mechanism 4 installed on the top of the base plate 1, the correction mechanism 4 being located at the bottom of the L-shaped plate 2, a photoelectric sensor 9 installed on the top of the L-shaped plate 2, an industrial camera 8 installed at the bottom of the L-shaped plate 2 near the sorting mechanism 6, and an intelligent AI control module 10 installed on one side of the L-shaped plate 2. The industrial camera 8, the intelligent AI control module 10, and an external power supply are electrically connected.
[0029] The copper-clad laminate is placed on conveyor belt 3. An external drive source rotates roller 5, which in turn drives conveyor belt 3 to move the copper-clad laminate. The laminate first passes through a correction mechanism 4, which adjusts it to the centerline of conveyor belt 3. After correction, the front end of the laminate passes through a photoelectric sensor 9 on top of L-shaped plate 2. The sensor sends a signal to intelligent AI control module 10, triggering industrial camera 8 at the bottom of L-shaped plate 2 to capture a high-definition image of the laminate surface. Industrial camera 8 transmits the image data to intelligent AI control module 10. The module runs a defect detection algorithm to analyze and determine whether the copper-clad laminate has defects. The system generates a pass / fail judgment result. If the result is pass / fail, the sorting mechanism 6 does not operate, and the copper-clad laminate continues to be conveyed with the conveyor belt 3. If the result is fail / fail, the intelligent AI control module 10 controls the sorting mechanism 6 to operate, pushing the fail / fail copper-clad laminate away from the conveyor belt 3 to the waste area, thus completing the sorting. In this way, the correction mechanism 4 can correct the position of the copper-clad laminate on the conveyor belt 3, preventing the position of the copper-clad laminate from shifting and ensuring the integrity of the image when the industrial camera 8 takes pictures. At the same time, it can be adjusted according to the width of the copper-clad laminate, thereby reducing downtime and improving adaptability. Furthermore, the sorting mechanism 6, in conjunction with the intelligent AI control module 10, can sort the copper-clad laminate.
[0030] In order to correct the deviation of the copper-clad laminate on conveyor belt 3, such as Figure 3 As shown, the correction mechanism 4 includes a slide rail 401, an intermediate block 402, a slider 403, a bracket 404, a motor 405, a correction box 406, a pulley 407, and a bidirectional screw 408. The two slide rails 401 are installed at the bottom of the base plate 1, the intermediate block 402 is fixed at the bottom of the base plate 1 and is located between the two slide rails 401, the slider 403 is slidably connected to the top of the slide rail 401, the bracket 404 is fixed to the top of the slider 403, the correction box 406 is fixed to one side of the bracket 404, the pulley 407 is rotatably connected to both sides of the inner wall of the correction box 406, the motor 405 is installed at the bottom of the base plate 1, the bidirectional screw 408 is fixed to the output end of the motor 405 and passes through and is rotatably connected to the inner wall of the intermediate block 402, the slider 403 is connected to the outer wall of the bidirectional screw 408 by a thread, and the threads at both ends of the bidirectional screw 408 are in opposite directions.
[0031] When it is necessary to change to a copper-clad laminate of different widths, the motor 405 is started, and its output end drives the bidirectional screw 408 to rotate. The sliders 403 on both sides are threadedly connected to the bidirectional screw 408. Under the restriction of the slide rail 401, they move synchronously in the opposite direction along the slide rail 401, driving the bracket 404 and the correction box 406 to move. Finally, the distance between the pulleys 407 on both sides is adjusted. The pulleys 407 on both sides and the correction box 406 form a guide channel with a wide entrance and a narrow exit. If the board material is offset to the left or right, its edge will contact one of the pulleys 407. The pulley 407 applies lateral force through rotational friction, gradually pushing the board material towards the center line of the channel and into the subsequent detection area. Thus, the distance between the pulleys 407 can be quickly adjusted by the motor 405. At the same time, the pulleys 407 can correct the offset and avoid scratching the surface of the copper-clad laminate.
[0032] In order to remove defective copper-clad laminates from conveyor belt 3, such as Figure 4 and Figure 5 As shown, the sorting mechanism 6 includes a connecting box 601, an electric push rod 602, a crank 603, a connecting rod 604, a lever 605, an extension plate 606, a drive rod 607, a gear 608, and a rack 609. The connecting box 601 is fixed to the top of the base plate 1. The electric push rod 602 is installed on one side of the connecting box 601, and the telescopic end of the electric push rod 602 passes through one side of the connecting box 601. The crank 603 is rotatably connected to the top of the connecting box 601, and the connecting rod 604 is rotatably connected to the top of the connecting box 601. The crank 603 is attached to the top, the extension plate 606 is fixed to one side of the connecting box 601, the lever 605 is rotatably connected to the top of the extension plate 606, and the connecting rod 604 is rotatably connected to the lever 605. The drive rod 607 is fixed to the bottom of the crank 603, the gear 608 is installed at the bottom of the drive rod 607, the rack 609 is fixed to the output end of the electric push rod 602, and the rack 609 meshes with the gear 608. The electric push rod 602 and the intelligent AI control module 10 are electrically connected.
[0033] When the intelligent AI control module 10 determines that the copper-clad laminate is unqualified, it sends a retraction signal to the electric push rod 602. The telescopic end of the electric push rod 602 retracts, causing the rack 609 to move horizontally and the gear 608 to rotate. This, in turn, drives the crank 603 to rotate around the top of the connecting box 601 via the drive rod 607. The crank 603 pushes the lever 605 via the connecting rod 604, causing the lever 605 to rotate around the top of the extension plate 606. Its end contacts the edge of the unqualified copper-clad laminate, pushing it away from the conveyor belt 3 to the waste area. At the same time, the electric push rod 602 retracts completely, and the rack 609 drives the gear 608 to rotate half a turn. At this time, the lever 605 can just push the copper-clad laminate out. Conversely, the electric push rod 602 extends, and the rack 609 drives the gear 608 to reverse. At this time, the lever 605 returns to its original position and tends to be parallel to the conveyor belt 3. Thus, in conjunction with the signal from the intelligent AI control module 10, qualified and unqualified products can be separated, thereby ensuring the quality of the shipped products.
[0034] Working principle: The copper-clad laminate is placed on the conveyor belt 3. An external drive source drives the roller 5 to rotate, which in turn drives the conveyor belt 3, causing the copper-clad laminate to move. The copper-clad laminate first passes through the correction mechanism 4, which adjusts it to the center line position of the conveyor belt 3. After correction, the front end of the copper-clad laminate passes through the photoelectric sensor 9 on the top of the L-shaped plate 2. The sensor sends a signal to the intelligent AI control module 10, triggering the industrial camera 8 at the bottom of the L-shaped plate 2 to take a picture of the surface of the copper-clad laminate and obtain a high-definition image. The industrial camera 8 transmits the image data to the intelligent AI control module 10. The module runs a defect detection algorithm to analyze and judge whether there are defects in the copper-clad laminate and generates a qualified or unqualified judgment result. If it is determined to be qualified, the sorting mechanism 6 does not move, and the copper-clad laminate continues to be conveyed with the conveyor belt 3. If it is determined to be unqualified, the intelligent AI control module 10 controls the sorting mechanism 6 to move and push the unqualified copper-clad laminate away from the conveyor belt 3 to the waste area, completing the sorting.
[0035] When it is necessary to change to a copper-clad board of different widths, the motor 405 is started, and its output drives the bidirectional screw 408 to rotate. The sliders 403 on both sides, being threadedly connected to the bidirectional screw 408, move synchronously in opposite directions along the slide rail 401 under the constraint of the slide rail 401. This moves the bracket 404 and the correction box 406, ultimately adjusting the distance between the pulleys 407 on both sides. The pulleys 407 and the correction box 406 form a guide channel with a wide entrance and a narrow exit. If the board material is offset to the left or right, its edge will contact one of the pulleys 407. The pulley 407 applies lateral force through rotational friction, gradually pushing the board material towards the center line of the channel and into the subsequent inspection area.
[0036] When the intelligent AI control module 10 determines that the copper-clad laminate is unqualified, it sends a retraction signal to the electric push rod 602. The telescopic end of the electric push rod 602 retracts, causing the rack 609 to move horizontally and drive the gear 608 to rotate. This, in turn, drives the crank 603 to rotate around the top of the connecting box 601 via the drive rod 607. The crank 603 pushes the lever 605 via the connecting rod 604, causing the lever 605 to rotate around the top of the extension plate 606. Its end contacts the edge of the unqualified copper-clad laminate, pushing it away from the conveyor belt 3 to the waste area. At the same time, the electric push rod 602 retracts completely, and the rack 609 drives the gear 608 to rotate half a turn. At this time, the lever 605 can just push the copper-clad laminate out. Conversely, the electric push rod 602 extends, driving the gear 608 to reverse through the rack 609. At this time, the lever 605 resets and tends to be parallel to the conveyor belt 3.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
