Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board testing technology, specifically a flexible circuit board testing device. Background Technology

[0002] Flexible circuit boards (PCBs) are a new type of circuit board. Due to their thinness, lightness, and flexibility, they are widely used in electronic products such as smartphones, tablets, and wearable devices. However, because flexible circuit boards have relatively weak mechanical properties, they are prone to deformation and damage. Therefore, they require strict quality testing to ensure their reliability and stability during use.

[0003] When testing flexible circuit boards (PCBs), they must first be fixed in place to ensure overall stability and prevent shaking when the testing instrument contacts them, thus guaranteeing accurate test results. A testing device for finished PCBs disclosed in patent CN220154246 U includes a movable plate, a right movable plate, a top plate, an upper pressure strip, an adjusting screw, a vertical guide rod, a universal ball joint, a parallelogram connecting rod, and an electric actuator. The electric actuator drives the left and right movable seats to move linearly towards each other. The positioning and adjusting components work together to press the upper pressure strip against the electric plate. However, this existing device has difficulty controlling the distance between the left and right movable seats when adjusting them. If the distance is too close, the PCB may bend due to excessive clamping force, making it difficult to maintain stable positioning and leading to test failure. Therefore, we propose a new PCB testing device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a flexible circuit board testing device, including a base 1, an adjustment and fixing mechanism 2 for fixing the flexible circuit board is provided on the top of the base 1, a reinforcement and fixing mechanism 3 for reinforcing and fixing the flexible circuit board is provided on the vertical surface of the adjustment and fixing mechanism 2 on the top of the base 1, and support legs are provided at the four corners of the bottom of the base 1.

[0022] It should be noted that this utility model has a mounting plate with mounting holes at the bottom of the support foot. The base 1 is mounted on the testing platform with fixing screws. Then, the flexible circuit board to be tested is placed on the base 1. The device is connected to an external power supply, and the servo motor 6 is controlled to rotate the bidirectional screw 4. The two moving plates 5 are threadedly connected to the two ends of the bidirectional screw 4, bringing the two moving plates 5 closer together. When the two moving plates 5 are close to the flexible circuit board, the movement of the moving plates 5 stops. Then, the rotary motor 8 is controlled to rotate the drum 7. The rotation of the drum 7 drives the adjustment... Rotate the adjustment plate 9 to press the pressure block 10 at the end of the adjustment plate 9 against both ends of the flexible circuit board. Then manually adjust the position of the two protruding plates 13. During adjustment, loosen the locking bolt 17 and then pull the protruding plate 13 to slide. After adjusting the position of the two sliders 14, tighten the locking bolt 17 and then pull up the pull plate 15. At this time, the spring 20 is compressed. Then release the pull plate 15. Under the action of the spring 20, the two pull plates 15 press against the other ends of the flexible circuit board, so that the entire flexible circuit board is stably positioned. Then, it can be tested by the tester on the test platform.

[0023] The adjusting and fixing mechanism 2 includes a movable plate 5, a rotating cylinder 7, a rotating motor 8, an adjusting plate 9, and a pressure block 10. The top of the base 1 has a horizontal groove, and a bidirectional screw 4 is rotatably connected in the groove. A servo motor 6 is fixedly installed at the end of the base 1, and the output shaft end of the servo motor 6 extends into the groove and is fixed to the bidirectional screw 4. The movable plate 5 is symmetrically slidably connected to the top of the base 1. The bottom of the two movable plates 5 is integrally provided with protrusions, and the two protrusions are symmetrically threaded to the two ends of the bidirectional screw 4. The top of the movable plate 5 has a U-shaped structure, and a rotating cylinder 7 is rotatably connected in the U-shaped groove of the movable plate 5. A rotating motor 8 is fixedly installed at the top of the side wall of the movable plate 5, and the output shaft end of the rotating motor 8 is fixedly connected to the central axis of the rotating cylinder 7. An adjusting plate 9 is fixedly connected to the outside of the rotating cylinder 7.

[0024] It should be noted that when positioning the flexible circuit board on the base 1, the servo motor 6 is controlled to rotate the bidirectional screw 4. The two moving plates 5 are connected to the two ends of the bidirectional screw 4 by threads, so that the two moving plates 5 are brought closer together. When the two moving plates 5 are close to the flexible circuit board, the movement of the moving plates 5 is stopped. Then, the rotary motor 8 is controlled to work to rotate the drum 7. The rotation of the drum 7 drives the adjustment plate 9 to rotate, so that the pressure block 10 at the end of the adjustment plate 9 is pressed against the two ends of the flexible circuit board, so that the flexible circuit board is pressed and fixed.

[0025] A pressure block 10 is integrally connected to the bottom of the adjusting plate 9 at the end away from the rotating drum 7, and an anti-slip pad 11 is fixedly connected to the outside of the pressure block 10.

[0026] It should be noted that after the pressure block 10 presses down on the flexible circuit board, the anti-slip pad 11 on the pressure block 10 comes into contact with the flexible circuit board, thereby increasing the friction between the pressure block 10 and the flexible circuit board and ensuring the stability of the flexible circuit board.

[0027] The fixing mechanism 3 includes a convex plate 13, a pull plate 15, a slider 14, a fixing hole 16, and a locking bolt 17. The top of the base 1 has symmetrically opened grooves 12 at both ends of the groove vertically, and the slider 14 is slidably connected in the grooves 12. The top of the slider 14 has a vertical sliding hole, and the slider rod 18 is slidably connected in the sliding hole. The top two ends of the slider 14 are provided with convex plates 13, and the convex plates 13 are slidably connected to the top of the base 1. The top of the slider rod 18 is fixedly connected to the pull plate 15, and the bottom of the slider rod 18 is fixedly connected to the limiting plate 19. A spring 20 is sleeved on the outside of the slider rod 18 between the limiting plate 19 and the slider 14.

[0028] It should be noted that when manually adjusting the position of the two protruding plates 13, loosen the locking bolt 17, then pull the protruding plate 13 to slide so that the position of the two sliders 14 is adjusted. Then tighten the locking bolt 17, and then pull up the pull plate 15. At this time, the spring 20 is compressed. Then release the pull plate 15. Under the action of the spring 20, the two pull plates 15 are pressed against the other two ends of the flexible circuit board, so that the entire flexible circuit board is stably positioned.

[0029] The top of the protruding plate 13 is symmetrically provided with locking bolts 17. The top of the base 1 is located outside the slide groove 12 and is symmetrically provided with fixing holes 16 at equal intervals. The end of the locking bolt 17 is threaded into the fixing hole 16.

[0030] It should be noted that multiple fixing holes 16 are equidistantly opened on both sides of the slide groove 12 at the top of the base 1. After adjusting the position of the slider 14, the position of the slider 14 can be fixed by connecting the locking bolt 17 to the fixing hole 16.

[0031] A pull ring is provided at the top of the pull plate 15.

[0032] Pulling the pull ring controls the raising and lowering of the pull plate 15, thereby pressing the pull plate 15 against the top of the flexible circuit board.

[0033] The top of the base 1 is symmetrically provided with guide grooves outside the groove, and the bottom of the movable plate 5 is symmetrically provided with guide blocks, which are slidably connected in the guide grooves.

[0034] It should be noted that during the movement of the movable plate 5 on the base 1, the guide block on it is slidably set in the guide groove to limit the movement of the movable plate 5 and realize the smooth movement of the movable plate 5.

[0035] The height of the bottom plane of the limiting plate 19 is higher than the height of the bottom support leg of the base 1.

[0036] It should be noted that a mounting plate with mounting holes is provided at the bottom of the support foot. The base 1 is installed on the testing platform with fixing screws. Then, the flexible circuit board to be tested is placed on the base 1, and the flexible circuit board is tested by the testing instrument on the testing platform.
