Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board testing technology, and in particular to a static bending force testing device for flexible circuit boards. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as flexible printed circuit boards or flexographic printed circuit boards, are small in size and light in weight, greatly reducing the size of devices. They are suitable for the development of electronic products towards high density, miniaturization, lightweight, thinness, and high reliability. They are highly flexible, allowing for free bending, winding, twisting, and folding. They can be used for three-dimensional wiring, arbitrarily arranged according to spatial layout requirements, changing shape, and moving and stretching freely in three-dimensional space, thereby achieving integrated component assembly and wire connection.

[0003] The manufactured flexible printed circuit boards (FPCBs) need to have their bending performance tested. Existing testing devices are limited in function, only capable of performing bending tests on FPCBs and unable to perform torsion tests or observe the performance of FPCBs under torsion. Therefore, there is an urgent need to develop a static bending force testing device for FPCBs that is simple in structure, easy to operate, and capable of performing both bending and torsion tests, thus overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0004] The purpose of this invention is to provide a static bending force detection device for flexible circuit boards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A static bending force detection device for a flexible circuit board includes a base, a fixed support frame, a movable support frame, a support shaft, a movable plate, a torsion mechanism, a clamping mechanism, and a bending drive mechanism. The fixed support frame is fixedly mounted on the base. A support shaft is rotatably connected to the base and fixedly connected to the movable support frame. A movable plate is disposed within the movable support frame. A rotating shaft is fixedly mounted on the movable plate and rotatably connected to the movable support frame. A torsion mechanism for driving the rotating shaft and movable plate to rotate is mounted on the movable support frame. A clamping mechanism is fixedly mounted on both the fixed support frame and the movable plate. A bending drive mechanism for driving the support shaft and movable support frame to rotate is mounted on the base.

[0007] Preferably, the torsion mechanism includes a first motor, a first gear, and a second gear. The first motor is fixed to the lower side of the movable support frame, the first gear is fixed on the output shaft of the first motor, and a second gear meshing with the first gear is installed on one side of the first gear. The second gear is fixed on the rotating shaft.

[0008] Preferably, the clamping mechanism includes a frame and clamping bolts, with two clamping bolts mounted on the frame.

[0009] Preferably, the bending drive mechanism includes a second motor, a driving wheel, a driven wheel, and a transmission belt. The second motor is fixed on the base, and the driving wheel is fixed on the output shaft of the second motor. The driving wheel is connected to the driven wheel via the transmission belt, and the driven wheel is fixedly installed on the support shaft.

[0010] The beneficial effects of this utility model are as follows: In use, the static bending force testing device for flexible circuit boards places both ends of the flexible circuit board onto a fixed support frame and a movable plate, respectively. Two clamping mechanisms clamp and fix the two ends of the flexible circuit board. A second motor drives the driving wheel and driven wheel to rotate, which in turn drives the support shaft to rotate. The support shaft then drives the movable support frame and movable plate to rotate around the support shaft, causing the flexible circuit board to bend around the support shaft, thus performing a bending test. Additionally, a first motor drives a first gear and a second gear to rotate, which in turn drives the rotating shaft and movable plate to rotate. One end of the flexible circuit board rotates with the movable plate while the other end remains fixed to the fixed support frame, causing the flexible circuit board to twist, thus testing the torsional performance of the flexible circuit board. In summary, this utility model has a simple structure, is easy to operate, and can perform both bending and torsional tests on flexible circuit boards, making it more comprehensive in function.
