Abstract
Description
Technical fields:
[0001] This utility model relates to the field of cable feeding technology, and in particular to a cable feeding mechanism for high-speed transmission FFC cables. Background technology:
[0002] FFC cable, also known as Flexible Flat Cable (FFC), is a type of flexible flat cable that allows for arbitrary selection of the number and spacing of wires, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. It is best suited for data transmission cables between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment.
[0003] The bonding process of FFC cables involves wire feeding, which involves feeding the wires side by side in a certain order to complete the bonding process of FFC cables. Therefore, a wire feeding mechanism suitable for FFC cables is needed. Utility model content:
[0004] The purpose of this invention is to provide a wire feeding mechanism for high-speed transmission FFC cables, which addresses the shortcomings of existing technologies. It can effectively transmit each wire in a certain order, prevent defects such as jumpers, overlapping wires, and empty wires, and is well-suited for the bonding process of FFC cables.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a wire feeding mechanism for high-speed transmission FFC cables, including a bracket, a wire roller rotatably connected to the bracket along the X-axis, and a wire-stopping roller rotatably connected to the bracket along the X-axis and located below the wire roller. The wire roller is provided with multiple guide rings, which are arranged side by side along the X-axis, and each pair of adjacent guide rings forms a wire loading groove.
[0006] A further improvement to the above scheme is that the wire loading groove includes a wire loading section and a wire releasing section located outside the wire loading section, and the opening of the wire releasing section gradually increases from the inside to the outside.
[0007] A further improvement to the above scheme is that the cross-sectional shape of the mounting segment is rectangular, and the cross-sectional shape of the laying segment is trapezoidal.
[0008] A further improvement to the above scheme is that the guide roller and each guide ring are an integral structure.
[0009] A further improvement to the above scheme is that each of the guide rings is spaced at equal intervals along the X-axis.
[0010] The beneficial effects of this utility model are as follows: This utility model provides a wire feeding mechanism for high-speed transmission FFC cable, including a bracket, a wire roller rotatably connected to the bracket along the X-axis, and a wire abutment roller rotatably connected to the bracket along the X-axis and located below the wire roller. The wire roller is provided with multiple guide rings, and each guide ring is arranged side by side along the X-axis. Each pair of adjacent guide rings forms a wire loading groove.
[0011] First, each wire is wound into the wire mounting groove of the wire roller of this invention. Then, each wire is wound around the abutment roller, which presses against the wires in the wire mounting groove. For example, when each wire is wound around the front end of the wire roller, it is wound around the rear end of the abutment roller. The wires are distributed in an S-shape between the wire roller and the abutment roller. The abutment roller presses against the wires in the wire mounting groove, which can prevent the wires from falling out of the wire mounting groove. This invention can be used to convey each wire in a certain order, and can prevent defects such as skipped wires, overlapping wires, and empty wires. It is well applicable to the bonding process of FFC ribbon cables. Attached image description:

[0015] Explanation of reference numerals in the attached drawings: 1. Bracket; 2. Guide roller; 3. Guide ring; 4. Wire loading groove; 5. Wire loading section; 51. Wire releasing section. Detailed implementation method:
[0016] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-3As shown, this utility model includes a support 1, a guide roller 2 rotatably connected to the support 1 along the X-axis, and a guide roller 3 rotatably connected to the support 1 along the X-axis and located below the guide roller 2. The guide roller 2 is provided with multiple guide rings 4, which are arranged side-by-side along the X-axis, and adjacent guide rings 4 form a wire mounting groove 5. First, each wire is wound into the wire mounting groove 5 of the guide roller 2, and then each wire is wound around the guide roller 3. The guide roller 3 then guides the wires in the wire mounting groove 5. Each wire is pressed against the other in the opposite direction. For example, when each wire is placed on the front end of the wire roller 2, each wire is then passed around the rear end of the abutment roller 3. The wires are distributed in an S-shape between the wire roller 2 and the abutment roller 3. The abutment roller 3 presses against the wires located in the wire mounting groove 5, which can prevent the wires from falling out of the wire mounting groove 5. This utility model can be well used to convey each wire in a certain order, and can prevent defects such as skipped wires, overlapping wires, and empty wires. It can be well applied to the bonding process of FFC ribbon cable.
[0017] Compared to designing the wire mounting groove 5 to be wider, not only can fewer wires be loaded simultaneously by the same size wire roller 2, but the loaded wires are also prone to lateral slippage in the wire mounting groove 5. Compared to designing the wire mounting groove 5 to be narrower, the wires are not easy to align and load into the wire mounting groove 5. The wire mounting groove 5 of this utility model includes a wire loading section 51 and a wire release section 52 located outside the wire loading section 51. The opening of the wire release section 52 gradually increases from the inside to the outside. Through this structural design, not only can a larger number of wires be loaded simultaneously without lateral slippage of the wires, but it is also easy to align and load each wire into the corresponding wire mounting groove 5, making it more practical.
[0018] In this embodiment, the cross-sectional shape of the mounting segment 51 is rectangular, and the cross-sectional shape of the laying segment 52 is trapezoidal.
[0019] The guide roller 2 and each guide ring 4 are integrated into one structure, which not only reduces the number of parts but also improves the overall structural strength. The guide rings 4 are less likely to fall off, thus enabling more stable transmission of each guide wire in a certain order.
[0020] In this embodiment, the guide rings 4 are equally spaced along the X-axis; of course, in other embodiments, the guide rings 4 can be designed to be unequally spaced according to specific usage requirements.
[0021] Working principle:
[0022] First, each wire is placed in the wire mounting groove 5 of the wire roller 2 of this invention. Then, each wire is wound around the abutment roller 3. The abutment roller 3 presses the wires in the wire mounting groove 5 against each other in the opposite direction. For example, when each wire is placed at the front end of the wire roller 2, it is wound around the rear end of the abutment roller 3. The wires are distributed in an S-shape between the wire roller 2 and the abutment roller 3. The abutment roller 3 presses the wires in the wire mounting groove 5 against each other, which can prevent the wires from falling out of the wire mounting groove 5. This invention can be well used to convey each wire in a certain order, and can prevent defects such as skipped wires, overlapping wires, and empty wires. It can be well applied to the bonding process of FFC ribbon cables.
[0023] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
