Description

Technical Field

[0001] This invention relates to circuit board testing equipment technology, and more specifically to an adjustable testing equipment for flexible circuit boards. Background Technology

[0002] Flexible circuit boards (PCBs) are circuit boards made with polyimide or polyester film as the substrate. They possess excellent properties such as light weight, thinness, and the ability to be freely bent and folded. After the PCBs are manufactured, they need to undergo tests such as tensile strength and bending angle resistance to identify the performance level of different types of PCBs.

[0003] Chinese invention patent CN114441303B discloses an adjustable testing device for flexible circuit boards. When an angle test is required on a flexible circuit board, the operator moves a geared disc through a side hole, causing the fixed disc to rotate. The operator can observe the rotation angle through a transparent viewing ring. The radius of the geared disc is larger than the radius of the fixed disc, ensuring that for the same rotation angle, the arc length of the geared disc is greater than that of the fixed disc, facilitating more accurate angle testing of the flexible circuit board. Simultaneously, after adjustment, the E-shaped plate is limited between the teeth of the geared disc by the central rod of the spring, thus achieving stable and quick limiting of the angle adjustment mechanism.

[0004] Existing equipment, due to the inherent flexibility of flexible circuit boards, suffers from poor control and cannot provide effective support in simulating different scenarios. Furthermore, the pressure applied during testing cannot be precisely controlled, resulting in localized continuous testing and thus providing only one type of test result, failing to accurately obtain the required data. Therefore, an adjustable testing device for flexible circuit boards has been developed. Summary of the Invention

[0014] As a further optimization of the present invention, the pressing component includes a connecting block fixedly connected to the base, and a ring is fixedly installed on the end of the connecting block near the side wall of the base, and a power component is fixedly installed on the outer surface of the ring.

[0015] As a further optimization of the present invention, a through hole is provided on the outer surface of the ring on the side away from the power component, and a rotating shaft is rotatably mounted on the inner wall of the through hole.

[0016] As a further optimization of the present invention, a power rod is rotatably mounted on the outer surface of the rotating shaft, and one end of the power rod extends to the outside of the ring and the other end extends to the inner cavity of the ring.

[0019] As a further optimization of the present invention, one side of the movable block is fixedly connected to the end of the power rod, and a telescopic component is fixedly installed on the inner wall of the movable block.

[0020] As a further optimization of the present invention, a pressing block is fixedly installed at the output end of the telescopic component, and the pressing block is used to perform pressing detection on the circuit board.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for 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 the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] Example: Please refer to Figures 1-8 An adjustable testing device for flexible circuit boards includes a base 1, a locking member 11 is provided at the end of the base 1, and an adjustment component 2 is fixedly installed at the end of the base 1 and on one side of the locking member 11, so as to adjust the state of the circuit board.

[0037] In this solution, the locking component 11 is a clamp or other fixing component used to secure one end of the circuit board. Simultaneously, it works with the adjusting component 2 to lock the other end of the circuit board. By adjusting the movement of the adjusting component 2, the circuit board in different states is simulated, making the data obtained during testing more accurate. Furthermore, the position of the flexible circuit board is precisely controlled to ensure its stability during transfer.

[0038] Furthermore, the adjustment component 2 includes a fixing plate 21 fixedly connected to the end of the base 1. The end of the fixing plate 21 is provided with a groove 211. A slider 23 is slidably installed on the inner wall of the groove 211. A limiting block 24 is fixedly installed on the end of the slider 23. An adjustment block 25 is slidably installed on the end of the limiting block 24.

[0039] In this embodiment, a limiting groove is provided at the end of the limiting block 24. When the adjusting block 25 moves laterally, the entire block moves along the inner wall of the limiting groove on the limiting block 24, thereby ensuring the stability of the adjusting block 25 during movement.

[0040] Simultaneously, when the adjusting block 25 is subjected to force and moves longitudinally, it drives the slider 23, which is fixedly installed on the limiting block 24, to move. Since the outer surface of the slider 23 is slidably connected to the inner wall of the groove 211, the slider 23 can move in conjunction with the adjusting block 25 on the inner wall of the groove 211 when the adjusting block 25 is subjected to force, until it reaches the optimal position and then stops.

[0041] When the transmission gear 252 rotates, it drives the entire adjusting block 25 to move. Since the inner wall of the adjusting block 25 is surrounded by protruding teeth, as the transmission gear 252 rotates from one side to the corresponding end, the adjusting block 25 slowly changes from lateral movement to longitudinal movement, and changes from longitudinal movement to lateral movement during continuous operation.

[0042] When the adjusting block 25 moves longitudinally, the slider 23 drives the limiting block 24 to move along the inner wall of the groove 211. When the adjusting block 25 moves laterally, the inner wall of the limiting block 24 restricts the adjusting block 25, enabling it to move laterally stably.

[0043] Furthermore, a drive block 26 is fixedly installed at the end of the adjusting block 25, and a positioning block 261 is fixedly installed at the end of the drive block 26.

[0044] Specifically, when the adjusting block 25 moves, it synchronously drives the driving block 26, which is fixedly installed at its end, to move. The positioning block 261 is a device with telescopic function, such as an electric telescopic rod. The output end of the electric telescopic rod is fixedly installed with a component with anti-slip function, such as a rubber block. When the positioning block 261 is activated, it drives the rubber block to move synchronously towards the end of the moving block 28 until it is tightly attached to its end, so that the positioning block 261 drives the moving block 28 to move synchronously.

[0045] Furthermore, a support block 27 is fixedly installed at the end of the fixed plate 21, and a support plate 271 is slidably installed at the end of the support block 27, with a moving groove 272 provided at the end of the support plate 271.

[0046] Specifically, a support groove is provided on one side of the support block 27, and the inner wall of the support groove is slidably connected to the outer surface of the end of the support plate 271. At the same time, when the moving block 28 moves, it drives the support plate 271 to move longitudinally along the inner wall of the support groove.

[0047] When the positioning block 261 separates from the moving block 28, the moving block 28 is driven to move along the inner wall of the moving groove 272, and the moving block 28 is protected.

[0048] Furthermore, a moving block 28 is slidably mounted on the inner wall of the moving groove 272. A limiting groove 281 is formed at the end of the moving block 28. The inner wall of the limiting groove 281 is slidably connected to the outer surface of the positioning block 261. At the same time, a clamping member 29 is rotatably mounted on the end of the moving block 28 to limit the end of the circuit board.

[0049] Specifically, when the moving block 28 is moved by force, the clamping member 29 at its end is driven to move synchronously. The end of the clamping member 29 is equipped with a device with power output, such as a motor. The motor drives the clamping member 29 to rotate, so that the clamping member 29 moves to a suitable position.

[0050] Clamping component 29 is a fixture or other component used to fix the circuit board end, and is used to precisely lock the circuit board end to facilitate subsequent testing.

[0051] Furthermore, a positioning plate 22 is fixedly installed on one side of the fixing plate 21, a driving component 221 is fixedly installed at the end of the positioning plate 22, and a transmission gear 252 is fixedly installed at the end of the driving component 221.

[0052] Specifically, the drive component 221 is a device with power output, such as a motor, and is connected to an external control device. When the drive component 221 is started, it synchronously drives the transmission gear 252, which is fixedly installed at its output end, to rotate.

[0053] Furthermore, a guide groove 251 is provided at the middle position of the adjusting block 25. The inner wall of the guide groove 251 is slidably connected to the outer surface of the end of the transmission gear 252, while the outer surface of the transmission gear 252 meshes with the inner wall of the adjusting block 25.

[0054] Specifically, since the outer surface of the transmission gear 252 meshes with the inner wall of the adjusting block 25, the adjusting block 25 is driven to move when the transmission gear 252 rotates. At the same time, the outer surface of the end of the transmission gear 252 slides along the inner wall of the guide groove 251, thereby ensuring the stability of the operation of the transmission gear 252.

[0055] When the adjusting block 25 is moved under force, it moves along the trajectory of the guide groove 251, thereby achieving horizontal or vertical movement. In conjunction with the clamping parts 29, the circuit board can be adjusted at will to simulate different scenarios and improve the accuracy of the test.

[0056] Furthermore, the pressing component 3 is assembled at the end of the base 1 and works with the adjusting component 2 to perform multi-directional testing of the circuit board; the pressing component 3 includes a connecting block 31 fixedly connected to the base 1, and a ring 32 is fixedly installed on the side of the connecting block 31 near the side wall of the base 1, and a power component 321 is fixedly installed on the outer surface of the ring 32.

[0057] In this embodiment, the power component 321 is a device with power output, such as a motor, and is connected to an external control device. When the power component 321 is started, it synchronously drives the power block 33, which is fixedly installed at its output end, to rotate.

[0058] Furthermore, a through hole 322 is formed on the outer surface of the ring 32 on the side away from the power component 321, and a rotating shaft 323 is rotatably mounted on the inner wall of the through hole 322. A power rod 34 is rotatably mounted on the outer surface of the rotating shaft 323, with one end of the power rod 34 extending to the outside of the ring 32 and the other end extending to the inner cavity of the ring 32. A power groove 341 is formed on one side of the power rod 34.

[0059] Specifically, when the power rod 34 is subjected to force, it rotates along the outer surface of the rotating shaft 323. The outer surface of the power rod 34 is slidably connected to the inner wall of the through hole 322 to protect the power rod 34 during operation and ensure the stability of the power rod 34.

[0060] Furthermore, a power block 33 is fixedly installed at the output end of the power component 321, and the outer surface of the end of the power block 33 is slidably connected to the inner wall of the power groove 341.

[0061] Specifically, when the power block 33 rotates, it drives the power rod 34, which is slidably mounted on its outer surface, to move. Since the outer surface of the end of the power block 33 is slidably connected to the inner wall of the power groove 341, when the power block 33 rotates, it drives the power rod 34 to reciprocate around the rotating shaft 323 until it moves to the appropriate position and then stops.

[0062] Furthermore, an arc-shaped block 36 is fixedly installed on the end of the connecting block 31 near the movable block 35. An arc-shaped groove 361 is formed at the end of the arc-shaped block 36, and the movable block 35 is slidably installed on the inner wall of the arc-shaped groove 361. One side of the movable block 35 is fixedly connected to the end of the power rod 34, and a telescopic member 351 is fixedly installed on the inner wall of the movable block 35. A pressing block 37 is fixedly installed at the output end of the telescopic member 351, and the circuit board is pressed and tested by the pressing block 37.

[0063] Specifically, when the movable block 35 moves with the power rod 34, the movable block 35 is constrained by the arc-shaped block 36, so that the movable block 35 remains stable as a whole when it moves.

[0064] Telescopic component 351 is an electric telescopic rod or other device with telescopic function, and is connected to an external control device. When telescopic component 351 moves, it synchronously drives the pressing block 37 fixedly installed at its output end to move. The end of the pressing block 37 is connected to the end of telescopic component 351 through a clamp or other fixing component, which facilitates the subsequent replacement of different types of pressing blocks 37.

[0065] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0066] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
