Description

Technical Field

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

[0002] Flexible circuit boards are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending ability.

[0003] Flexible circuit boards need to be bent at a certain angle during actual use. However, the bending life of the connection is not tested during actual use, which makes it impossible to accurately obtain the actual usage situation and determine the number of times it can be used. This makes the usage situation unpredictable and affects the connection effect.

[0004] Therefore, a flexible circuit board connection bending life testing device is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a supporting base plate, a push plate slidably disposed on one side above the supporting base plate, and a support plate fixedly disposed on the other side above the supporting base plate, wherein a first insertion groove and a second insertion groove are formed on the upper surface of the support plate;

[0007] A sliding plate is provided on the side of the lower end of the push plate away from the first and second insertion slots, and a mechanical recorder is provided between the push plate and the support plate.

[0008] Preferably, the upper surface of the push plate is curved in the middle to form a pressing arc surface, and the lower surface of the push plate is straight.

[0009] Preferably, a bending groove is provided at the front end of the lower surface of the push plate, and the lower surface of the bending groove is stepped with the lower surface of the push plate.

[0013] Preferably, a connecting rod for rotational support is installed on one side of the mechanical recorder, and the connecting rod is located on the sliding track.

[0014] Compared with the prior art, this utility model provides a flexible circuit board connection bending life testing device, which has the following beneficial effects:

[0015] 1. The flexible circuit board connection bending life testing equipment uses a pusher plate that is manually pushed to move towards the flexible circuit board and pressed against it. Based on the flexibility of the flexible circuit board itself and the support of the support plate surface, the flexible circuit board is bent on the support plate surface, thus achieving the bending operation.

[0016] 2.

[0024] 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.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 The flexible circuit board connection bending life testing device in this embodiment includes a support base plate 1, a push plate 2 slidably disposed on one side above the support base plate 1, and a support plate 3 fixedly disposed on the other side above the support base plate 1. A first insertion groove 301 and a second insertion groove 302 are provided on the upper surface of the support plate 3.

[0027] A sliding plate 8 is provided on the side of the lower end of the push plate 2 away from the first insertion slot 301 and the second insertion slot 302, and a mechanical recorder 9 is provided between the push plate 2 and the support plate 3.

[0028] First, the flexible circuit board is inserted into the first insertion slot 301 and the second insertion slot 302 of suitable specifications. Then, iron wire or external parts are inserted into the first insertion slot 301 or the second insertion slot 302 at the same time to form a limit on the insertion part of the flexible circuit board, ensuring that the lower half is firmly connected during the bending operation and preventing displacement.

[0029] After the flexible circuit board is inserted and fixed, the pusher plate 2 is manually pushed to move it to one side of the flexible circuit board and press it. Based on the flexibility of the flexible circuit board itself and the support of the support plate 3, the flexible circuit board is bent on the surface of the support plate 3, thus achieving the bending operation. With the mechanical recorder 9 timing the number of times the pusher plate 2 is pushed, the number of bends can be recorded while the flexible circuit board is being bent, and the number of bends required to cause damage can be detected, thereby achieving the effect of testing its bending life.

[0030] The upper surface of push plate 2 is curved in the middle to form a pressing arc surface 201, and the lower surface of push plate 2 is straight.

[0031] A bending groove 202 is provided at the front end of the lower surface of the push plate 2, and the lower surface of the bending groove 202 and the lower surface of the push plate 2 are stepped.

[0032] A limit block 4 is magnetically attached to the upper end of the support plate 3. The upper surface of the inner part of the bending groove 202 is slightly higher than the upper surface of the support plate 3, and the upper surface of the limit block 4 is slightly higher than the upper surface of the front half of the push plate 2.

[0033] By setting the pressing arc surface 201 to have a certain curvature, it fits the palm of the hand better, making it more comfortable to use. By setting the height difference between the push plate 2, bending groove 202, support plate 3, and limit block 4, the bending accuracy of the flexible circuit board is ensured, and the accuracy of bending detection is improved.

[0034] The upper end of the support base plate 1 is provided with two parallel sliding strips 5. The sliding strips 5 are provided with inverted T-shaped grooves 6 for sliding support. Several sliders 7 are slidably arranged in the grooves 6. The slide plate 8 is fixedly arranged on the upper end of the sliders 7 and the slide plate 8 is fixedly arranged on the lower surface of the push plate 2.

[0035] By setting the slider 7 to a shape that adapts to the slide groove 6, the stability of the slider 7 when sliding within the slide bar 5 is ensured. With the connection of the slide plate 8, the accurate sliding of the push plate 2 is ensured, while the stability of the movement trajectory of the slide plate 8 itself is ensured. Under the synchronous guidance of the slide bars 5 on both sides, the accuracy of the movement direction of the push plate 2 and the slide plate 8 is improved.

[0036] The first insertion slot 301 and the second insertion slot 302 have the same length and depth, and the width of the second insertion slot 302 is greater than the width of the first insertion slot 301.

[0037] By setting two different specifications of first insertion slot 301 and second insertion slot 302, the device can achieve the effect of positioning flexible circuit boards of different specifications, thereby improving the applicability of the device.

[0038] A connecting rod 10 for rotational support is installed on one side of the mechanical recorder 9, and the connecting rod 10 is located on the moving track of the slide plate 8;

[0039] The mechanical recorder 9 can record data in a timely manner when the sliding plate 8 pushes the connecting rod 10. Since the connecting rod 10 is an existing device that is already in actual use and is well known to those in the field, it is not described in detail in this embodiment.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
