[0002] Copper clad laminate (CCL) is the core material for printed circuit boards (PCBs), and its surface quality directly affects the electrical performance, reliability, and processing yield of PCBs. Defect detection in CCL is a critical quality control step throughout the entire production process. During inspection, CCL needs to be placed on an inspection platform, and various instruments must be used to complete the defect detection.

[0003] To prevent displacement of copper-clad laminates during defect detection, they are typically clamped and positioned using fixtures after being placed on the inspection table. However, most fixtures employ a rigid frame and fixed-spaced gripper structure, resulting in insufficient versatility. Consequently, when inspecting copper-clad laminates of different specifications, it is necessary to frequently change suitable fixtures, thereby affecting the inspection efficiency. Solving these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0008] By adopting the above technical solution, after the micro air pump is started, the inside of the air chamber can be pressurized, and the high-pressure gas inside the air chamber can enter the interior of the mobile chamber through the connecting ring.

[0009] Preferably, one end of the connecting rod is fixedly connected to one side of the second spring, and the end of the connecting rod away from the second spring passes through the moving chamber and the detection platform, and is slidably connected to the moving chamber and the detection platform respectively.

[0010] By adopting the above technical solution, the second spring can drive the connecting rod to move on the surface of the moving chamber and the surface of the detection platform.

[0011] Preferably, the card frame is fixedly connected to one end of the connecting rod through the detection platform, and the bottom of the card frame is located inside the slide rail and is slidably connected to the slide rail.

[0012] By adopting the above technical solution, when the connecting rod moves, it can drive the clamping frame to slide inside the slide rail and clamp the copper-clad board placed on the surface of the testing platform.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4 A copper-clad laminate defect inspection station includes an inspection platform 1, a support plate 2, and a lighting fixture 3. The support plate 2 is fixedly connected to the outer wall of the inspection platform 1, the lighting fixture 3 is fixedly connected to the surface of the support plate 2, and a clamping component 4 is provided on the surface of the inspection platform 1.

[0025] The clamping assembly 4 includes an air chamber 401, a miniature air pump 402, a movable chamber 403, a rubber ball 404, a movable rod 405, a bent plate 406, a connecting ring 407, a first spring 408, a second spring 409, a connecting rod 410, a clamping frame 411, and a slide rail 412. The air chamber 401 is fixedly connected to the bottom of the detection platform 1, and the miniature air pump 402 is fixedly connected to the bottom of the detection platform 1. The miniature air pump 402 is connected to the air chamber 401. After the miniature air pump 402 is started, it can clean the inside of the air chamber 401. The pressurized, movable chamber 403 is fixedly connected to the bottom of the detection platform 1. A rubber ball 404 is positioned below the detection platform 1. A movable rod 405 is fixedly connected to the top of the rubber ball 404. A lifting component 5 is provided at the top of the movable rod 405. A curved plate 406 is fixedly connected to the outer wall of the movable rod 405. A connecting ring 407 is fixedly connected to the top of the curved plate 406. The connecting ring 407 communicates with both the movable chamber 403 and the air chamber 401. High-pressure gas inside the air chamber 401 can enter through the connecting ring 407. Inside the movable chamber 403, spring 408 is fixedly connected to the surface of the curved plate 406, spring 409 is fixedly connected to the inner wall of the movable chamber 403, and connecting rod 410 is disposed inside the movable chamber 403. One end of connecting rod 410 is fixedly connected to one side of spring 409, and the end of connecting rod 410 away from spring 409 passes through the movable chamber 403 and the detection platform 1, and is slidably connected to the movable chamber 403 and the detection platform 1 respectively. The arrangement of spring 409 can drive connecting rod 410 to move. The surface of the chamber 403 moves with the surface of the testing platform 1. The clamping frame 411 is set on the top of the testing platform 1. The clamping frame 411 and the connecting rod 410 are fixedly connected through one end of the testing platform 1. The slide rail 412 is opened on the top of the testing platform 1. The bottom of the clamping frame 411 is located inside the slide rail 412 and is slidably connected to the slide rail 412. When the connecting rod 410 moves, it can drive the clamping frame 411 to slide inside the slide rail 412 and clamp the copper-clad laminate placed on the surface of the testing platform 1.

[0026] When it is necessary to clamp the copper-clad laminate placed on the surface of the inspection platform 1, the spring 409 and the connecting rod 410 drive the clamping frame 411 to slide inside the slide rail 412 until the surface of the clamping frame 411 contacts the surface of the copper-clad laminate, thus completing the clamping of the copper-clad laminate. Since the position of the clamping frame 411 can be adjusted, copper-clad laminates of different specifications can be placed on the surface of the inspection platform 1 and clamped and fixed by the clamping frame 411. This solves the problem that the existing clamps of the copper-clad laminate defect inspection station cannot be applied to copper-clad laminates of different specifications, resulting in insufficient versatility.

[0027] The lifting assembly 5 includes a lifting rod 501, a push plate 502, and a track 503. The lifting rod 501 is fixedly connected to the top end of the moving rod 405. The air chamber 401 is located on the outer wall of the lifting rod 501 and is slidably connected to the outer wall of the lifting rod 501. The top end of the lifting rod 501 penetrates the detection platform 1 and is slidably connected to the detection platform 1. A pushing force is applied to the rubber ball 404, which can drive the lifting rod 501 to slide on the surface of the air chamber 401 and the surface of the detection platform 1 through which it is penetrated. The push plate 502 is disposed on the surface of the detection platform 1, and the bottom of the push plate 502 is fixedly connected to the top end of the lifting rod 501. The track 503 is opened on the surface of the detection platform 1, and the push plate 502 is located inside the track 503 and is slidably connected to the track 503. When the lifting rod 501 moves, it can drive the push plate 502 to slide inside the track 503.

[0028] After the surface defect detection of the copper-clad laminate is completed, the lifting rod 501 is driven by the rubber ball 404 to lift the copper-clad laminate through the push plate 502. At this time, the operator can replace the copper-clad laminate through the gap between the lifted copper-clad laminate and the detection platform 1, avoiding the situation where the copper-clad laminate is too tightly attached to the detection platform 1, which would make it difficult to replace the copper-clad laminate.

[0029] The working principle of this copper-clad laminate defect inspection station is as follows: The copper-clad laminate is placed on the surface of the push plate 502, and the pushing force on the rubber ball 404 is stopped. Under the influence of gravity, the rubber ball 404 drives the bending plate 406 and the push plate 502 to descend. When the push plate 502 moves into the interior of the track 503, the copper-clad laminate will be placed flat on the surface of the inspection platform 1. At the same time, when the bending plate 406 moves, it will cause the connecting ring 407 to separate from the air chamber 401 and the moving chamber 403 respectively. This prevents the compressed air inside the air chamber 401 from applying sufficient pressure to the interior of the moving chamber 403. This causes the spring 409 to drive the clamping frame 411 to reset through the connecting rod 410 and clamp the copper-clad laminate. At this time, the copper-clad laminate is fixed. Turning on the lighting fixture 3 allows the copper-clad laminate to be inspected. The surface is inspected. After the inspection is completed, the rubber ball 404 is pushed upward, causing the rubber ball 404 to push the bending plate 406 and the push plate 502 to move. The bending plate 406 pushes the connecting ring 407 to connect with the air chamber 401, and the micro air pump 402 is started. The micro air pump 402 pressurizes the air inside the moving chamber 403 through the air chamber 401 and the connecting ring 407, so that the connecting rod 410 pushes the frame 411 to move under the action of compressed air, so that the frame 411 separates from the copper-clad laminate. At the same time, when the push plate 502 moves under the drive of the lifting rod 501, it will move inside the track 503. When the top of the push plate 502 contacts the bottom of the copper-clad laminate, the push plate 502 will push the copper-clad laminate to lift. At this time, the replacement of the copper-clad laminate can be completed.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
