Description

Technical Field

[0001] This utility model relates to the field of electronic device processing technology, specifically to a fixture for in-situ bending of ribbon cables and synchronous assembly of buttons. Background Technology

[0002] In modern industrial automation systems, flexible printed circuits (FPCs) are widely used as key interconnect components for signal transmission in various electronic devices. To adapt to the installation requirements of different structural layouts, flexible circuits often need to undergo plastic deformation in space to achieve assembly matching. Traditional production processes typically use specialized bending fixtures to pre-form the ribbon cables, and then assemble them with button modules manually. However, this method cannot handle the complex situation of multi-angle bending of ribbon cables: when multi-angle bending is required, the assembly of ribbon cables and button modules becomes difficult, and manual assembly is inefficient; manual assembly operations are prone to damaging the ribbon cables, affecting the post-assembly effect and leading to unstable product quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a fixture for in-situ bending of ribbon cables and simultaneous assembly of buttons. The fixture provided by this invention can handle complex situations involving multi-angle bending of ribbon cables and difficult button assembly, eliminating manual assembly and improving efficiency.

[0004] This utility model provides a fixture for in-situ bending of ribbon cables and synchronous assembly of buttons, including a fixture body and a Z-axis pre-pressure limiting mechanism. The fixture body and the Z-axis pre-pressure limiting mechanism are detachably connected. A first station is provided on the working surface of the fixture body for positioning the button, on which the ribbon cable to be bent is placed. A structural pressure head is provided on the Z-axis pre-pressure limiting mechanism corresponding to the first station. The first station and the structural pressure head cooperate to form a three-dimensional positioning structure for constraining the spatial degree of freedom of the button. An operation guide channel is provided on the fixture body for guiding the bending working head to achieve bending deformation of the ribbon cable.

[0005] In one embodiment, a receiving slot matching the button is provided on the first workstation.

[0006] In one embodiment, a limiting boss is provided at the bottom of the receiving groove, and the limiting boss cooperates with the circular hole of the button.

[0007] In one embodiment, the fixture body has a through hole at the bottom of the receiving groove for placing the first bending deformation part of the cable to be bent.

[0008] In one embodiment, a through second guide channel is provided on the fixture body. The second guide channel is used to guide the bending working head of the second bending mechanism to move along a predetermined trajectory to achieve the second bending deformation of the wire to be bent.

[0009] In one embodiment, a through third guide channel is provided on the fixture body. The third guide channel is located in the middle of the receiving groove and is connected to the receiving groove.

[0010] In one embodiment, a second station is provided on one side of the first station. The second station is used to position the original state of the wiring. The second station cooperates with the structural pressure head to form a three-dimensional positioning structure.

[0011] In one embodiment, the fixture body is provided with a side edge and a top edge at the second work station. The side edge is used for positioning the original state of the cable in the X-axis direction, and the top edge is used for positioning the original state of the cable in the Y-axis direction.

[0012] In one embodiment, a through first guide channel is provided on the fixture body.

[0013] In one embodiment, the structural pressure head includes a central main body and two side support plates, the side support plates being used to constrain the degree of freedom of the products in the Z-axis direction at the first and second workstations.

[0014] The beneficial effects of the fixture for in-situ bending of the ribbon cable and synchronous assembly of the buttons provided in this embodiment of the utility model are as follows:

[0015] This utility model integrates a first workstation for placing buttons and ribbon cables, as well as an operation guide channel for guiding the bending head. The ribbon cable is bent directly on the button in situ, which can solve the complex situation of multi-angle bending of ribbon cables and high difficulty of button assembly, save manual assembly and improve efficiency.

[0016] This invention features a second station on one side of the first station. The second station performs a first bending process on the original wiring harness, forming a wiring harness with the first bending deformation. This wiring harness is then transferred to the first station for final bending and assembly with the buttons. Integrating two bending stations onto a single fixture shortens the product's movement distance between the first and second stations, improving production efficiency and saving costs.

The bending guide channel is used to guide the bending working head to achieve bending deformation of the ribbon cable, thereby realizing the in-situ bending and forming of the ribbon cable directly on the button 4, which can cope with the complex situation of multi-angle bending of ribbon cables and high difficulty of button assembly.

[0034] The first workstation 3 is provided with a receiving groove 7 that matches the button 4. In this embodiment, the depth of the receiving groove 7 matches the height of the button 4.

[0040] The second station 15 is used to perform the first bending process on the original state ribbon cable 21 to form a ribbon cable 5 with the first bending deformation 18. The ribbon cable 5 is then transferred to the first station 3 for final bending and assembly with the button 4.

[0041] The fixture body 1 is provided with a side edge 16 and a top edge 17 at the second work station 15. The side edge 16 is used for positioning the original state cable 21 in the X-axis direction, and the top edge 17 is used for positioning the original state cable 21 in the Y-axis direction. In this embodiment, the side edge 16 can be a positioning pin, with two pins spaced apart on both sides of the original state cable 21 to achieve positioning of the original state cable 21 in the X-axis direction; the top edge 17 is located on the other side of the first bending deformation 18 of the original state cable 21.

[0042] like Figure 12As shown, a through first guide channel 11 is provided on the fixture body 1.
