Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a quick-change multi-angle adjustable bending carrier board device. Background Technology

[0002] In the electronics industry, flexible printed circuit boards (FPCs) have a risk of delamination in weak areas of the FPC design, which needs to be confirmed. This is usually done using a bending fixture. The bending fixture is typically a hinge type. The area at risk of delamination is manually bent repeatedly at a frequency of 50 / 100 times, and then sent to the laboratory for X-ray imaging and cross-section confirmation.

[0003] In traditional technology, an FPC typically has multiple line fault risk points that need to be confirmed, which requires the use of multiple fixtures for monitoring, resulting in high fixture costs. Moreover, fixtures cannot be shared for multiple FPCs, requiring the use of multiple fixtures, which further increases fixture costs. In addition, when a line fault risk point on an FPC needs to be verified at multiple angles, multiple fixtures need to be switched, which wastes time and is inconvenient to operate.

The limiting block stop post is used to block and limit the second clamp seat to restrict the rotation angle of the second clamp seat.

[0017] Optionally, the telescopic adjustment structure includes a telescopic adjustment seat disposed on the first clamping seat, a telescopic adjustment block slidably disposed on the telescopic adjustment seat, and a telescopic adjustment rod rotatably disposed on the telescopic adjustment seat and threadedly engaged with the telescopic adjustment block, wherein the end face of the telescopic adjustment block is clamped between the first clamping plate to form the adjustable clamping gap.

[0018] Optionally, the telescopic adjustment seat includes an adjustment seat connecting plate protruding from the top surface of the first clamp seat, and an adjustment seat limiting block disposed on the top of the adjustment seat connecting plate, wherein the telescopic adjustment rod is rotatably disposed on the side of the top of the adjustment seat connecting plate or on the side of the adjustment seat limiting block.

[0019] The telescopic adjustment block has an adjustment block limiting groove in the middle of its top surface, and a sliding limiting groove communicating with the adjustment block limiting groove is provided through the middle of the top surface of the telescopic adjustment block.

[0024] The beneficial effects of the technical solution provided by this utility model include:

[0025] When a bending test is required at the fault location of a flexible printed circuit board (FPCB), one side of the FPCB can be fixedly clamped to a fixed fixture, while the other side can be movably clamped to a rotating fixture, placing the fault location between the fixed and rotating fixtures. The FPCB can then be rotated using the rotating fixture, thus bending the fault location. Furthermore, the rotation angle of the rotating fixture can be limited by a rotating adjustment positioning structure, ensuring that the bending angle at the fault location meets the testing requirements.

[0026] Furthermore, by incorporating a telescopic adjustment structure and a first clamping plate into the fixed fixture, the adjustable clamping gap between the telescopic adjustment structure and the first clamping plate can be adjusted. This facilitates adjustment of the position of the flexible board clamped at the adjustable clamping gap, thereby adjusting the location of the circuit break risk on the flexible board between the adjustable clamping gap of the fixed fixture and the movable clamping gap of the rotating fixture. This allows for bending tests at different locations on the flexible board with circuit break risks, and also facilitates bending tests on different flexible boards with circuit break risks. Moreover, the rotation adjustment positioning structure can limit and adjust the rotation angle of the second fixture seat, thereby adjusting the bending angle of the rotating fixture on the flexible board with circuit break risks to meet the requirements of different bending test angles. In this way, a single bending test device can perform bending tests on multiple circuit break risks on one or more FPCs, eliminating the need for multiple fixtures, significantly reducing fixture costs, and simplifying the bending operation of the flexible board, saving time and improving testing efficiency.

[0036] 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, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1 to 2 As shown, this utility model proposes a quick-change multi-angle adjustable bending plate device 10, including a device base 100, a fixed clamp 200 and a rotating clamp 300 arranged side by side on one side of the device base 100, and a rotation adjustment and positioning structure 400 arranged on the other side of the device base 100. The rotating clamp 300 and the fixed clamp 200 cooperate with each other, and the rotation adjustment and positioning structure 400 and the rotating clamp 300 cooperate with each other.

[0038] When a bending test is required at the point of potential line fault on the flexible printed circuit board (FPCB), one side of the FPCB can be fixedly clamped onto the fixed clamp 200, while the other side can be movably clamped onto the rotating clamp 300, so that the point of potential line fault on the FPCB is located between the fixed clamp 200 and the rotating clamp 300. Then, the FPCB can be rotated using the rotating clamp 300, thereby bending the point of potential line fault. Furthermore, the rotation angle of the rotating clamp 300 can be limited by rotating the positioning structure 400, ensuring that the bending angle at the point of potential line fault on the FPCB meets the testing requirements.

[0039] Specifically, the fixing fixture 200 may include a first fixture seat 210 fixedly mounted on the device base 100, and a telescopic adjustment structure 220 and a first clamping plate 230 mounted on the first fixture seat 210, with an adjustable clamping gap formed between the telescopic adjustment structure 220 and the first clamping plate 230. The telescopic adjustment structure 220 is telescopic and movable, and the distance between it and the first clamping plate 230 can be adjusted, thereby adjusting the size of the adjustable clamping gap. The adjustable clamping gap can be used to clamp or release a portion of the flexible plate.

[0040] Furthermore, the rotating clamp 300 may include a second clamp seat 310 rotatably mounted on the device base 100, and a clamping block 320 and a second clamping plate 330 mounted on the second clamp seat 310. A movable clamping gap is formed between the clamping block 320 and the second clamping plate 330, and the movable clamping gap corresponds to and cooperates with the adjustable clamping gap. Using the movable clamping gap between the clamping block 320 and the second clamping plate 330, another portion of the flexible plate can be movably clamped. Moreover, by rotating the second clamp seat 310, the clamping block 320 and the second clamping plate 330 on it can be rotated, thereby rotating the other portion of the flexible plate clamped in the movable clamping gap.

[0041] By providing the fixed clamp 200 with a telescopic adjustment structure 220 and a first clamping plate 230, the adjustable clamping gap between the telescopic adjustment structure 220 and the first clamping plate 230 can be adjusted via the telescopic adjustment structure 220. This facilitates adjustment of the position of the flexible board clamped at the adjustable clamping gap, thereby adjusting the location of the line fault risk of the flexible board between the adjustable clamping gap of the fixed clamp 200 and the movable clamping gap of the rotating clamp 300. This makes it convenient to perform bending tests on the line fault risk points at different positions of the flexible board, and also facilitates bending tests on the line fault risk points of different flexible boards.

[0042] Furthermore, the rotary adjustment positioning structure 400 is mounted on the device base 100 and located on the rotation side of the second clamp seat 310, used to limit and adjust the rotation angle of the second clamp seat 310. The rotary adjustment positioning structure 400 can also limit and adjust the rotation angle of the second clamp seat 310, thereby adjusting the bending angle of the rotating clamp 300 relative to the circuit breakage risk of the flexible circuit board, meeting the requirements of different bending test angles.

[0043] In this way, a single bending test device can be used to detect bending at multiple line breakage risk points of one or more FPCs without the need for multiple fixtures, which can greatly reduce fixture costs and eliminate the need to switch between different fixtures. This simplifies the bending operation of the flexible board, saves time, and improves testing efficiency.

[0044] Furthermore, such as Figures 2 to 3 As shown, the device base 100 may include a base main board 110 and a plurality of support feet 120 disposed around the bottom of the base main board 110. The first clamp seat 210 of the fixed clamp 200 and the second clamp seat 310 of the rotating clamp 300 may both be mounted on one side of the base main board 110; the rotation adjustment and positioning structure 400 may be disposed on the other side of the base main board 110.

[0045] In addition, such as Figures 1 to 2 and such Figures 4 to 5 As shown, the first clamping seat 210 of the fixing clamp 200 is detachably mounted on the base main board 110, which can fix the entire fixing clamp 200 on the base main board 110. Furthermore, the telescopic adjustment structure 220 may include a telescopic adjustment seat 222 disposed on the first clamping seat 210, a telescopic adjustment block 224 slidably disposed on the telescopic adjustment seat 222, and a telescopic adjustment rod 226 rotatably disposed on the telescopic adjustment seat 222 and threadedly engaged with the telescopic adjustment block 224. An adjustable clamping gap is formed between the end face of the telescopic adjustment block 224 and the first clamping plate 230. The telescopic adjustment rod 226 and the telescopic adjustment block 224 can be configured as a screw and nut structure. By rotating the telescopic adjustment rod 226, the telescopic adjustment block 224 can be driven to telescopically move on the telescopic adjustment seat 222, causing the end face of the telescopic adjustment block 224 to move closer to or further away from the first clamping plate 230. This allows adjustment of the adjustable clamping gap, enabling clamping and fixing or loosening of a portion of the flexible plate through the adjustable clamping gap.

[0046] When clamping and fixing a portion of the flexible plate using the adjustable clamping gap, the other portion of the flexible plate can also be clamped and limited by rotating the clamping gap of the clamp 300, making it easy to rotate and bend the flexible plate by rotating the clamp 300. When it is necessary to adjust the clamping and fixing part of the flexible plate or to loosen the clamping of the flexible plate, the telescopic adjustment structure 220 can be telescopically adjusted so that the end face of the telescopic adjustment block 224 releases the clamping of the flexible plate from the first clamping plate 230.

[0047] Furthermore, the telescopic adjustment seat 222 may include an adjustment seat connecting plate 2222 protruding from the top surface of the first clamp seat 210, and an adjustment seat limiting block 2224 disposed on the top of the adjustment seat connecting plate 2222. The telescopic adjustment rod 226 is rotatably disposed on the side of the top of the adjustment seat connecting plate 2222 or the side of the adjustment seat limiting block 2224. Moreover, the middle of the top surface of the telescopic adjustment block 224 may be provided with an adjustment block limiting groove 2242, and the middle of the top surface of the telescopic adjustment block 224 is provided with a sliding limiting groove 2244 communicating with the adjustment block limiting groove 2242. The adjustment seat connecting plate 2222 is limited in the sliding limiting groove 2244, the adjustment seat limiting block 2224 is limited in the adjustment block limiting groove 2242, and the telescopic adjustment block 224 is limited between the adjustment seat limiting block 2224 and the first clamp seat 210.

[0048] The telescopic adjustment block 224 can be configured as a U-shaped block structure with an adjustment block limiting groove 2242 in the middle. It can be movably fitted onto the adjustment seat connecting plate 2222 using the sliding limiting groove 2244, allowing the adjustment seat limiting block 2224 to reciprocate along the adjustment seat connecting plate 2222 when driven by the telescopic adjustment rod 226, ensuring stability and reliability. Furthermore, the adjustment seat limiting block 2224 at the top of the adjustment seat connecting plate 2222 can limit the telescopic adjustment block 224 (the width of the adjustment seat limiting block 2224 is greater than the width of the sliding limiting groove 2244, thus limiting the telescopic adjustment block 224 to the adjustment seat connecting plate 2222). Moreover, the adjustment seat limiting block 2224 is detachably mounted on the adjustment seat connecting plate 2222, facilitating the installation and positioning of the telescopic adjustment block 224.

[0049] Furthermore, the bottom of the side of the first clamping plate 230 can be connected to the side of the first clamping seat 210, and the top of the side of the first clamping plate 230 protrudes above the first clamping seat 210 and corresponds to the end face of the telescopic adjustment structure 220. This allows for the clamping or releasing of a portion of the flexible plate using the top of the first clamping plate 230 and the end of the telescopic adjustment block 224 of the telescopic adjustment structure 220. The first clamping plate 230 is detachably mounted on the side of the first clamping seat 210, facilitating installation, disassembly, and maintenance.

[0050] In addition, the telescopic adjustment rod 226 may include a telescopic main rod body rotatably mounted on the telescopic adjustment seat 222 and threadedly engaged with the telescopic adjustment block 224, and a first rotating handle located at the end of the telescopic main rod body. The first rotating handle may protrude beyond the device base 100 to facilitate rotation of the telescopic adjustment rod 226.

[0051] In addition, such as Figures 1 to 2 and such Figures 6 to 7 As shown, the second clamping seat 310 of the rotating clamp 300 may include a second main seat 312 rotatably mounted on the device base 100, and a clamping rotating rod 314 protruding from the side of the second main seat 312. The rotation adjustment and positioning structure 400 corresponds to and cooperates with the clamping rotating rod 314. The clamping block 320 and the second clamping plate 330 are disposed on the second main seat 312. For example, as Figure 3 As shown, a rotating base 130 can be provided on the device base 100, and a second main body 312 can be provided on the rotating base 130. By pushing the clamp rotating rod 314, the second main body 312 can be rotated, thereby causing the clamping block 320 and the second clamping plate 330 on the second main body 312 to rotate together. This allows the flexible plate portion clamped in the movable clamping gap between the clamping block 320 and the second clamping plate 330 to be rotated, thereby bending the line breakage risk point of the flexible plate located between the movable clamping gap and the adjustable clamping gap. In addition, the clamp rotating rod 314 may include a rotating main rod protruding from the side of the second main body 312, and a second rotating handle provided at the end of the rotating main rod. The second rotating handle may be located outside the second clamping base 310, facilitating the rotation of the rotating clamp 300 via the second rotating handle.

[0052] Furthermore, the clamping block 320 may include a clamping block body 322 disposed on the top surface of the second clamping seat 310, and a clamping block plate 324 disposed on the end face of the clamping block body 322. The top of the clamping block plate 324 protrudes beyond the top surface of the clamping block body 322 and is disposed opposite to the second clamping plate 330. Moreover, the bottom of the side of the second clamping plate 330 is connected to the side of the second clamping seat 310, and the top of the side of the second clamping plate 330 protrudes above the second clamping seat 310 and is disposed opposite to the side of the clamping block plate 324. Thus, the clamping block plate 324 on the end face of the clamping block 320 and the second clamping plate 330 on the side of the second clamping seat 310 can form an active clamping gap for moving and limiting the position of the flexible plate.

[0053] Furthermore, elliptical connecting holes (or oblong connecting holes) can be provided on the clamping block body 322 or the second clamping seat 310, so that the clamping block body 322 and the second clamping seat 310 can be detachably connected through the elliptical connecting holes and connecting screws. The installation position of the clamping block body 322 can be finely adjusted as needed, thereby adjusting the distance between the clamping block clamping plate 324 and the second clamping plate 330, that is, the width of the movable clamping gap, which can meet the clamping requirements of flexible boards of different thicknesses.

[0054] Furthermore, both the first clamping plate 230 and the second clamping plate 330 may include a clamping plate bottom mounting portion detachably mounted on the side of the first clamping seat 210 or the second clamping seat 310, and a clamping plate body protruding vertically from the clamping plate bottom mounting portion. The thickness of the clamping plate bottom mounting portion is greater than the thickness of the clamping plate body, making the connection between the clamping plate (including the first clamping plate 230 or the second clamping plate 330) and the clamping seat (including the first clamping seat or the second clamping seat 310) more reliable. Moreover, clamping seat mounting grooves may be provided on the side of the first clamping seat 210 and the side of the second clamping seat 310, and the clamping plate bottom mounting portion may be installed in the clamping seat mounting groove, so that the outer side of the clamping plate (including the first clamping plate 230 or the second clamping plate 330) is flush with the outer side of the clamping seat. In addition, in the initial state, the outer side of the first clamping plate 230 and the outer side of the second clamping plate 330 may be located on the same plane or at a preset angle position, which is convenient for clamping and positioning flexible boards of different shapes.

[0055] In addition, such as Figures 1 to 3 As shown, the rotary adjustment and positioning structure 400 may include a rotary limiting block 410 detachably mounted on the device base 100, the rotary limiting block 410 being located on the rotation side of the second clamp seat 310. The rotary limiting block 410 can block the clamp rotation rod 314 of the rotary clamp 300, allowing it to rotate only by a limited angle. This allows the rotary clamp 300 to bend the flexible plate at a limited angle, thus satisfying the preset bending angle requirement.

[0056] Furthermore, in some embodiments, the device base 100 may be provided with multiple adjustment mounting holes 420, all of which are located on the rotation side of the second clamp seat 310. The rotation limiting block 410 is detachably installed in any one of the adjustment mounting holes 420. Thus, by changing the adjustment mounting hole 420 on which the rotation limiting block 410 is installed on the device base 100, the limiting position of the rotation limiting block 410 can be changed, thereby adjusting the limiting angle of the rotation limiting block 410 on the clamp rotation rod 314 of the rotating clamp 300 to meet the different bending angle requirements of the flexible board.

[0057] Furthermore, multiple adjustment mounting holes 420 can be arranged in an arc shape on the device base 100, extending from the side where the second clamping plate 330 is located to the side where the first clamping plate 230 is located. By arranging the multiple adjustment mounting holes 420 in an arc shape, the limiting angle of the rotation limiting block 410 can be adjusted more conveniently by changing the installation position of the rotation limiting block 410.

[0058] Furthermore, in some embodiments, the device base 100 may be provided with an adjustment mounting groove located on the rotation side of the second clamp seat 310, and the rotation limiting block 410 may be detachably mounted at any position in the adjustment mounting groove. Similarly, by changing the mounting position of the rotation limiting block 410 in the adjustment mounting groove on the device base 100, the limiting position of the rotation limiting block 410 can be changed, thereby adjusting the limiting angle of the rotation limiting block 410 on the clamp rotation rod 314 of the rotating clamp 300 to meet the different bending angle requirements of the flexible board. Moreover, there may be one or more adjustment mounting grooves.

[0059] Furthermore, the adjustment mounting groove can be arranged in an arc shape on the device base 100, extending from the side where the second clamping plate 330 is located to the side where the first clamping plate 230 is located. Similarly, by setting the adjustment mounting groove as an arc-shaped groove, the limiting angle of the rotation limiting block 410 can be adjusted more conveniently by changing the installation position of the rotation limiting block 410.

[0060] In this embodiment, the device base 100 may be provided with a plurality of adjustment mounting holes 420 evenly arranged in an arc shape, extending from the side where the second clamping plate 330 is located to the side where the first clamping plate 230 is located. Furthermore, the rotation limiting block 410 may include a limiting block connecting rod 412 movably inserted into any one of the adjustment mounting holes 420, and a limiting block stop post 414 sleeved on the limiting block connecting rod 412 and located on the top surface of the device base 100. The limiting block stop post 414 is used to block and limit the second clamping seat 310, thereby limiting the rotation angle of the second clamping seat 310. In this way, the rotation limiting block 410 can be easily pulled out from one adjustment mounting hole 420 and placed into another adjustment mounting hole 420, thus achieving adjustment of the limiting angle of the rotation limiting block 410, which is simple and convenient.

[0061] The quick-change multi-angle adjustable bending carrier plate device 10 provided by this utility model can be used for multiple FPCs (flexible printed circuit boards) and multiple circuit fault risk points. It eliminates the need to repeatedly purchase special bending fixtures, thus avoiding cost waste and excessively long processing and delivery times for multiple special fixtures, thereby reducing production costs and production cycles. Moreover, the bending degree of the flexible board can be adjusted in a very short time according to requirements, which is convenient for on-site operation verification.
