Description

Technical Field

[0001] The present invention relates to the technical field of FPC cable processing, and in particular to a Z-shaped FPC cable bending device. Background Art

[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 Z-type FPC cables, such as Figure 1 As shown, the whole is in sheet shape, including a middle section 03 and two parallel connecting sections 01. The ends 02 of the two connecting sections 01 are provided with connecting terminals. In specific application scenarios, it is necessary to bend the end 02 of one of the connecting sections 01 into a U-shaped structure to meet product requirements. There is no bending device for this Z-shaped FPC cable in the existing technology, and the shape and dimensional accuracy of the bending cannot be ensured. Summary of the Invention

[0003] The purpose of the present invention is to provide a Z-shaped FPC cable bending device to address the problem that there is no bending device in the prior art for bending the end of a connecting segment of a Z-shaped FPC cable and the shape and dimensional accuracy of the bending cannot be ensured.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is: A Z-shaped FPC cable bending device includes a base, a positioning structure is provided on the top of the base, and the positioning structure can position the Z-shaped FPC cable laid flat on the top of the base; a flap is hinged on the top of the base, and a pressure strip is provided on the flap; a magnetic structure is provided between the flap and the base, and when the flap is flipped over to be magnetically fixed to the base, the flap and the pressure strip simultaneously press the connecting section to be bent on the Z-shaped FPC cable against the base; the flap is crimped to the middle position of the connecting section; the pressure strip is perpendicular to the connecting section and is crimped to a position on the connecting section near the end; the end can be bent upward and tightly against the outer contour surface of the pressure strip to form a U-shaped structure at the end.

[0005] The present invention adopts the above-mentioned technical solution. When the Z-shaped FPC cable needs to be bent, the Z-shaped FPC cable is first laid flat on the top of the base and positioned through the positioning structure. The flip cover is then flipped over to be fixed to the base by magnetic attraction. At this time, the flip cover presses the connecting section of the Z-shaped FPC cable onto 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 connecting section. Finally, the end of the connecting section is manually bent upward and close to the outer contour surface of the pressure strip. The end is formed into a U-shaped structure by the pressure strip. Compared with the existing technology, There is no bending device for bending the end of a connecting segment of a Z-shaped FPC cable in the art, and the problem of being unable to ensure the shape and dimensional accuracy of the bend cannot be solved. The present invention provides a bending device that can be used for bending the end of the connecting segment of a Z-shaped FPC cable. The FPC cable is positioned by a positioning structure and is pressed by a flip cover and a pressure strip. The crimping position of the pressure strip on the connecting segment is preset to ensure the bending dimensional accuracy of the end of the connecting segment. The end of the connecting segment is shaped by the outer contour of the pressure strip to ensure its bending shape accuracy. At the same time, the bending operation is simple and the production efficiency is high.

[0006] Furthermore, the positioning structure includes a baffle and a positioning groove, the positioning groove is in a through "I" shape, and is used to position the connecting section embedded therein in the width direction; the baffle is arranged at one end of the positioning groove, and is used to abut against the end of the connecting section to achieve length direction positioning of the connecting section.

[0007] Furthermore, the two ends of the baffle are respectively a connecting end and a positioning end, the connecting end is fixed on the base, and a gap is left between the positioning end and one side edge of the base; before bending the end, the end extends out of the edge and abuts against the positioning end; this arrangement makes it easy for the operator to bend the end of the connecting section upward by hand.

[0008] Furthermore, the fixed position of the connecting end on the base can be adjusted; the fixed position of the connecting end on the base can be adjusted to change the size of the gap between the positioning end and the edge; in this way, the length of the connecting section end extending out of the edge can be adjusted, and then the crimping position of the pressure strip on the connecting section can be adjusted to change the bending length of the connecting section end to adapt to different technical requirements.

[0009] 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 connecting section can be changed; in this way, by changing the crimping position of the pressure strip on the connecting section, the bending length of the end of the connecting section can be changed to adapt to different technical requirements.

[0010] Furthermore, the flip cover is provided with a strip hole or a strip notch, and the pressure strip can be fixed at different positions of the strip hole or the strip notch by bolts to achieve position adjustment of the pressure strip on the flip cover; the position adjustment is achieved by setting the strip hole or the strip notch, the structure is simple and easy to implement.

[0011] 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.

[0012] 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.

[0013] Furthermore, the base is in the shape of a "mouth" frame structure; such a configuration is conducive to lightweighting and is convenient for manual movement of the bending device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: providing a bending device that can be used for bending the end of a Z-shaped FPC cable connection segment, positioning the FPC cable through a positioning structure and pressing it through a flip cover and a pressure strip, presetting the crimping position of the pressure strip on the connection segment, ensuring the bending dimensional accuracy of the end of the connection segment, shaping the end of the connection segment through the outer contour of the pressure strip, ensuring its bending shape accuracy; at the same time, the bending operation is simple and the production efficiency is high.
