Technical Field

[0002] The appearance of electronic products varies, which means that the internal parts and wiring harnesses need to be processed twice in order to fit the product. FPC cables (flexible circuit board cables) are common parts and wiring harnesses in electronic products and are widely used in mobile phones, computers, printers and other devices. FPC cables use flexible insulating materials as the base material and have good bendability. They can be bent multiple times without damaging the circuit. This feature allows FPC cables to be flexibly designed according to the actual needs of the product. FPC cables have different shapes, and the areas that need to be bent are also different. For L-shaped FPC cables, such as Figure 1 As shown, the whole is in sheet shape, including a bending section 01, a connecting section 02 and a main section 03. The ends 04 of the two connecting sections 02 and the end of the main section 03 are provided with connecting terminals. In specific application scenarios, the ends 04 of the two connecting sections 02 need to be bent into a U-shaped structure to meet product requirements. There is no bending device for this L-shaped FPC cable in the existing technology, and the shape and dimensional accuracy of the bending cannot be ensured. Summary of the Invention

[0005] The present invention adopts the above-mentioned technical solution, when the L-shaped FPC cable needs to be bent, the L-shaped FPC cable is first placed in the positioning groove for positioning, and then the flip cover is flipped over to be fixed with the base by magnetic attraction. At this time, the flip cover presses the bent section of the L-shaped FPC cable on the base to ensure the flatness of the area near the connecting section of the FPC cable. At the same time, the pressure strip presses the two connecting sections of the L-shaped FPC cable. Finally, the end of the connecting section is manually bent upward and close to the outer contour surface of the pressure strip, and the end is formed into a U-shaped structure by the pressure strip. Compared with the prior art, there is no In order to solve the problem that a bending device for bending the ends of the two connecting segments of an L-shaped FPC cable cannot ensure the shape and dimensional accuracy of the bending, the present invention provides a bending device that can be used for bending the ends of the connecting segments of an L-shaped FPC cable. The FPC cable is embedded in a positioning groove and pressed by a flip cover and a pressure strip, so that the FPC cable is accurately positioned.

At the same time, the bending operation is simple and the production efficiency is high.
[0006] Furthermore, before the ends are bent, the ends of any connecting segments extend out of the edge of the base; this arrangement makes it easier for an operator to manually bend the ends of the connecting segments upwards.

[0008] Furthermore, the pressure strip is fixedly installed on the flip cover, and the installation position of the pressure strip on the flip cover can be adjusted; by adjusting the installation position of the pressure strip on the flip cover, the crimping position of the pressure strip on the two connecting sections can be changed; in this way, by changing the crimping position of the pressure strip on the two connecting sections, the bending length of the end of the connecting section can be changed to adapt to different technical requirements.
[0009] Furthermore, the flip cover is provided with a strip hole, and the pressure strip can be fixed to different positions of the strip hole by bolts to achieve position adjustment of the pressure strip on the flip cover; the position adjustment is achieved by setting the strip hole, the structure is simple, and it is easy to implement.
[0010] Furthermore, the magnetic structure includes a first magnet located on the flip cover and a second magnet located on the base, and the first magnet and the second magnet attract each other to achieve magnetic fixation of the flip cover and the base.
[0011] Furthermore, a pin hole positioning structure is provided between the base and the flip cover; when the flip cover is flipped over to be magnetically fixed to the base, the flip cover and the base are positioned by the pin hole positioning structure; such a setting ensures that the relative position of the flip cover and the base is accurate, thereby ensuring the accurate crimping position of the pressure strip on the connecting section and ensuring the bending accuracy.
[0012] Furthermore, the base is a "mouth"-shaped frame structure; such a configuration is conducive to lightweighting and is convenient for manual movement of the bending device.
