Description

Technical Field

[0001] This utility model relates to the field of FFC production technology, specifically to an FFC bending fixture with precisely adjustable dimensions. Background Technology

[0002] FFC, or Flexible Flat Cable, is a new type of data cable made of PET insulation material and extremely thin tinned flat copper wire, pressed together by high-tech automated production lines. Due to its flexibility, ability to be bent and folded at will, thinness, and small size, it is widely used in electronic devices for connecting components such as motherboards, displays, cameras, and batteries. In the production process of electronic devices, FFC often needs to be bent according to the internal space layout of the device to achieve efficient and compact wiring.

[0003] While current FFC bending fixtures can be adjusted to position the bending parts, the adjusted positions are mostly only suitable for positioning bends with equal spacing. For products that require bending of many parts, since the intervals between bending parts may vary, the fixture needs to be adjusted after each bend to position the next bending part. This operation is cumbersome and the processing efficiency is low. Therefore, an FFC bending fixture with precise dimensional adjustment is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the aforementioned technical problems, this invention provides an FFC bending fixture with precise size adjustment. This solution solves the problem that while current FFC bending fixtures can be adjusted to position the bending parts, the adjusted positions are mostly only suitable for positioning bends with equal spacing. For products that require bending of many parts, since the intervals between bending parts may vary, the fixture needs to be adjusted after each bend to position the next bending part, which is cumbersome and results in low processing efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An FFC bending fixture with precise size adjustment includes a base, a support seat fixedly connected to the upper end of the base, a support platform fixedly connected to the upper end of the base in front of the support seat, a support plate and a positioning platform connected to the upper end of the support platform, a second positioning groove and several evenly distributed first positioning grooves opened at the upper end of the positioning platform, positioning blocks slidably connected inside the first and second positioning grooves, a sliding groove opened through the upper end of the positioning block, a first positioning pin slidably connected inside the sliding groove, several evenly distributed positioning holes opened at the bottom inner side of the first and second positioning grooves, one end of the first positioning pin threadedly connected to the inside of the positioning hole, a cylinder fixedly installed at the front end of the support seat, a fixing frame fixedly connected to the output end of the cylinder, several evenly distributed second positioning pins fixedly connected to the front end of the fixing frame, a bending plate and a clamping block slidably connected to the outer surface of the second positioning pin, a nut threadedly connected to the outer surface of the second positioning pin, and an adjusting seat slidably connected to the upper end of the support platform.

[0007] Preferably, the second positioning groove is inclined.

[0008] Preferably, a threaded rod is rotatably connected between the positioning platform and the support plate, and the adjusting seat is threaded to the outer surface of the threaded rod.

[0009] Preferably, one end of the threaded rod passes through the rear end of the support plate and is fixedly connected to a knob.

[0010] Preferably, the upper end of the support platform is an inclined surface, and the lower end of the bent plate is perpendicular to the upper end of the support platform.

[0011] Preferably, the bending plate is held between the fixing frame and the clamping block.

[0012] The advantages of this utility model compared with the prior art are:

[0013] This solution proposes a precisely adjustable FFC bending fixture. By setting a second positioning groove and multiple first positioning grooves in conjunction with a sliding positioning block, slide, first positioning pin, and positioning hole, multi-dimensional precise positioning of the FFC bending position is achieved. The multiple first positioning grooves allow for positioning of different bending parts of the same FFC wire in a single processing cycle with only one fixture adjustment, eliminating the need to adjust the fixture after each bend and improving production efficiency. The inclined second positioning groove can work with the bending groove to achieve bending operations at a certain angle, increasing the bending flexibility of the fixture. The bending plate is clamped between the fixed frame and the clamping block by a nut, which can be easily disassembled and replaced to adapt to different processing requirements.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figure 1 and Figure 2 As shown, an FFC bending fixture with precise size adjustment includes a base 1, a support base 2 fixedly connected to the upper end of the base 1, a support platform 3 fixedly connected to the upper end of the base 1 in front of the support base 2, a support plate 4 and a positioning platform 5 connected to the upper end of the support platform 3, a second positioning groove 7 and several evenly distributed first positioning grooves 6 formed on the upper end of the positioning platform 5, positioning blocks 9 slidably connected inside the first positioning grooves 6 and the second positioning grooves 7, a sliding groove 11 penetrating the upper end of the positioning block 9, and a first positioning pin 10 slidably connected inside the sliding groove 11. The inner bottom of the positioning groove 6 and the second positioning groove 7 are provided with several evenly distributed positioning holes 8. One end of the first positioning pin 10 is threaded into the inside of the positioning hole 8. The front end of the support base 2 is fixedly installed with a cylinder 12. The output end of the cylinder 12 is fixedly connected with a fixing frame 13. The front end of the fixing frame 13 is fixedly connected with several evenly distributed second positioning pins 14. The outer surface of the second positioning pin 14 is slidably connected with a bending plate 15 and a clamping block 16. The outer surface of the second positioning pin 14 is threadedly connected with a nut 17. The upper end of the support platform 3 is slidably connected with an adjusting seat 19.

[0020] Furthermore, a bending groove is formed between the positioning platform 5 and the adjusting seat 19. The bending plate 15 is moved down by the cylinder 12 to bend the FFC wire in the bending groove. Multiple first positioning grooves 6 are used to position different bending parts of the same FFC wire. The first positioning pin 10 and the positioning hole 8 are used to initially position the positioning block 9. By passing the first positioning pin 10 through the slide groove 11 and threaded to the positioning hole 8, the positioning block 9 can be fixed near the positioning hole 8, thereby initially adjusting the distance between the bending grooves of the positioning block 9. After the positioning block 9 is initially fixed, the first positioning pin 10 can be slid in the slide groove 11 by sliding the positioning block 9, which can further fine-tune the distance between the positioning block 9 and the bending groove. When the positioning block 9 is adjusted to the appropriate position, the positioning block 9 can be fixed by tightening the first positioning pin 10 to abut against the positioning block 9, thereby ensuring the accuracy of subsequent positioning.

[0021] Furthermore, before bending, the distance between each positioning block 9 and the bending groove is adjusted sequentially from left to right so that the distance difference between two adjacent positioning blocks 9 and the bending groove is consistent with the interval length between two adjacent bending parts of the FFC wire. Then, the FFC wire is placed in the leftmost first positioning groove 6, with one end of the FFC wire abutting against the positioning block 9. The part of the FFC wire that extends into the bending groove is the corresponding first bending part. At this time, the cylinder 12 is activated to drive the bending plate 15 to press down, and the first bending part can be bent. Then, following the above placement steps, the FFC wire is placed in the remaining first positioning grooves 6 in order from left to right and bent, thus completing the bending of multiple parts of the FFC wire.

[0022] Furthermore, the second positioning groove 7 is inclined to cooperate with the bending groove to achieve a bending operation at a certain angle, and its adjustment method is the same as that of the first positioning groove 6.

[0023] Furthermore, a threaded rod 18 is rotatably connected between the positioning table 5 and the support plate 4, and the adjusting seat 19 is threadedly connected to the outer surface of the threaded rod 18.

[0024] Furthermore, one end of the threaded rod 18 passes through the rear end of the support plate 4 and is fixedly connected to a knob 20. By rotating the knob 20, the threaded rod 18 can be rotated, thereby adjusting the distance between the positioning table 5 and the adjusting seat 19, and thus adjusting the size of the bending groove.

[0025] Furthermore, the upper end of the support platform 3 is an inclined surface, and the lower end of the bent plate 15 is perpendicular to the upper end of the support platform 3.

[0026] Furthermore, the bending plate 15 is clamped between the fixing frame 13 and the clamping block 16.

[0027] Furthermore, the bending plate 15 is locked in place by the nut 17 and can be disassembled and replaced to adapt to different processing requirements.

[0028] Furthermore, the threaded rod 18 is positioned to avoid the positions corresponding to the bending groove, the first positioning groove 6, and the second positioning groove 7, thus preventing interference with the bending.

[0029] Furthermore, the positioning platform 5 is tilted towards the front end of the base 1 to facilitate operation by staff and reduce discomfort caused by prolonged bending over due to the horizontal placement of the positioning platform 5.

[0030] Working principle: In use, the distance between each positioning block 9 and the bending groove is adjusted sequentially from left to right so that the distance difference between two adjacent positioning blocks 9 and the bending groove is consistent with the interval length between two adjacent bending parts of the FFC wire. Then, the FFC wire is placed in the leftmost first positioning groove 6, with one end of the FFC wire abutting against the positioning block 9. The part of the FFC wire that extends into the bending groove is the corresponding first bending part. At this time, the cylinder 12 is activated to drive the bending plate 15 to press down, which can bend the first bending part. Then, following the above placement steps, the FFC wire is placed in the remaining first positioning grooves 6 in the order from left to right and bent in sequence to complete the bending of multiple parts of the FFC wire.
