Description

Technical Field

[0001] The invention relates to a wire external force winding mechanism, belonging to the technical field of wire winding. Background Art

[0002] At present, the polyimide wires on the market are mainly composed of the following structures: the non-shielded polyimide wire is a wire core that is directly wrapped with a polyimide film by a half-lap method; the shielded polyimide wire is a non-shielded polyimide wire with a shielding layer added to the outer layer and then wrapped with a layer of polyimide film. The polyimide film is generally composed of a three-layer structure, with a polyimide film in the middle layer and FEP hot melt adhesive evenly distributed on both sides, which are FEP layer-polyimide layer-FEP layer in sequence. The outer insulation layer and sheath of the wire are both consolidated by a sintering wrapping process, which produces directional shrinkage during sintering, and the films are tightly held together, and the films are bonded together by positive pressure;

[0003] After long-term use, the sheath of polyimide wire peels off, and the adhesion between the unshielded polyimide wire and the polyimide film is weakened, resulting in the sheathing of the wire, causing the shield and the wire core to be exposed to the air, affecting signal transmission. Summary of the invention

[0004] The purpose of the present invention is to provide a wire external force winding mechanism, which can restore the original wire adhesion state after the sheath peels off, so that the FEP coating can be re-adhered to the polyimide film, ensuring that the shielding and the wire core will not be directly exposed to the air, thereby ensuring signal transmission.

[0006] The carrier plates include two, a wire rotating wheel is arranged between the two carrier plates; a wire pulling wheel is arranged on the outer side of one of the carrier plates;

[0008] The load-bearing shaft has an angle with the wire rotating wheel and is movably connected, and both ends are connected to bearings; the wire traction wheel is rotatably connected to the bearing through a rod.

[0009] Furthermore, two wire grooves are provided on the outer extension of the wire rotating wheel for leading out the silver-plated copper wire, and are consistent with the wire outlet of the wire traction wheel.

[0010] Furthermore, the inner ring of the wire rotating wheel is provided with a notch for facilitating the insertion of the silver-plated copper wire.

[0011] Furthermore, a wire fixing hole is provided at the center of the carrying plate.

[0013] Furthermore, the wire traction wheel is provided with a rotating handle.

[0014] Furthermore, the bearing shaft includes a bearing shaft 1 and a bearing shaft 2; and scales are arranged on the bearing shaft 1 and the bearing shaft 2.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the present invention can ensure that the external force acts evenly on the outer sheath of the conductor, and by preparing the rotation angle, the direction of the force applied can be calculated to be consistent with the winding direction of the polyimide film, which further facilitates the accuracy of positioning and reduces errors;

[0016] The silver-plated copper wire is wound by the wire rotating wheel, and the silver-plated copper wire is evenly wound on the wire to be modified according to the rotation of the wire traction wheel, so that the FEP coating can be re-adhered to the polyimide film, ensuring that the shielding and the wire core are not directly exposed to the air, thereby ensuring signal transmission; this practical information further facilitates the accuracy of positioning and reduces errors by setting scales on the load-bearing shaft.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, a wire external force winding mechanism is disclosed, comprising:

[0023] The carrier disk 1 includes two carrier disks, and a wire rotating wheel 2 is provided between the two carrier disks 1; a wire pulling wheel 6 is provided on the outer side of one of the carrier disks 1, and the wire pulling wheel 6 is provided with a rotating handle 9; a wire fixing hole 7 is provided at the center of the carrier disk 1; a wire placing groove 12 is provided at the center of the wire rotating wheel 2, and the purpose of the wire fixing hole 7 and the wire placing groove 12 is to facilitate the placement of the wire;

[0024] A carrier frame 13, wherein the carrier plate 1 is disposed in the carrier frame 13 and connected to the carrier frame 13 via a fixing member 11; bearings 5 ​​are symmetrically arranged at the gap between the carrier plate 1 and the carrier frame 13;

[0025] The load-bearing shaft is angularly movably connected to the wire rotating wheel 2, and both ends are connected to the bearings 5; the wire traction wheel 6 is rotatably connected to the bearing 5 through a rod, and the load-bearing shaft includes a load-bearing shaft 1 3 and a load-bearing shaft 2 4; scales are set on the load-bearing shaft 1 3 and the load-bearing shaft 2 4. In order to ensure the accurate calculability of the angle, scales need to be set on the rotating and moving parts to facilitate the accuracy of positioning and reduce errors.

[0026] Two wire grooves 10 are provided on the outer extension of the wire rotating wheel 2 for leading out the silver-plated copper wire and are consistent with the wire outlet of the wire pulling wheel 2; a notch 8 is provided on the inner ring of the wire rotating wheel 2 for convenient insertion of the silver-plated copper wire.

[0027] Working principle: First, the two ends of the wire are fixed through the wire fixing hole 7, and the silver-plated copper wire is wound forwardly in one of the wire slots 10 on the wire rotating wheel 2, and the silver-plated copper wire is wound on the outer insulation skin of the wire through the notch 8. The angle between the silver-plated copper wire and the wire is determined by the scales set on the bearing shaft 1 3 and the bearing shaft 2 4 and the diameter of the wire rotating wheel 2 itself;

[0028] The wire traction wheel 6 and the wire rotating wheel 2 are both carried by 3 bearing shafts 1 and 4 bearing shafts 2. The wire traction wheel 6 and the wire rotating wheel 2 only have axial relative movement. The silver-plated copper wire is reversely wound in another wire groove of the wire rotating wheel 2 and introduced into the wire of the wire traction wheel 6. The wire groove diameter of the wire traction wheel 6 is the same as the wire groove diameter of the wire rotating wheel 2. The wire traction wheel 6 moves first and the wire rotating wheel 2 is driven, and synchronous movement is ensured. When the wire traction wheel 6 rotates, it will pull the wire rotating wheel 2 to rotate and slide axially. While the silver-plated copper wire in the second wire groove moves forward and unfolds, the first wire groove moves in the opposite direction to the silver-plated copper wire and unfolds, so that the silver-plated copper wire is always wrapped around the wire at a fixed angle.

[0029] In order to ensure that the external force acts evenly on the outer sheath or insulation of the wire, the external force needs to act continuously around the peeling and cannot cause wrinkles on the outer sheath or insulation of the wire. Therefore, the direction of force application needs to be consistent with the winding direction of the polyimide film.

[0030] The outer sheath or insulation of the conductor is rewound according to its own winding direction. In order to ensure that the direction of external force application is consistent with the winding direction of the polyimide film of the conductor (the angle between the film and the middle axis of the conductor), it is necessary to fix both sides of the peeled conductor to ensure that the conductor is straight and centered. At the same time, the device of the present invention is designed in the middle of the conductor fixing frame, which can not only locate the angle with the middle axis, but also move along the middle axis to ensure that the metal wire is continuously wound and knotted at both ends of the peeled conductor, thereby ensuring that the polyimide film is always wrapped around the conductor core or shielding layer.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
