Description

Technical Field

[0001] The invention relates to the technical field of wire processing equipment, in particular to an electric heating cutting device and a cutting method for a wire aluminum foil layer. Background Art

[0002] With the development of new energy vehicles, more and more new energy vehicle wiring harnesses use wires with aluminum foil layers to shield the interference of irrelevant external signals on the transmission signals, so as to obtain a better human-computer interaction experience when using the terminal, such as improving the anti-interference ability of signal transmission of in-vehicle intelligent voice interaction systems, carlife, etc.

[0003] The conductor with aluminum foil layer generally includes an outer insulation layer, an aluminum foil layer, a shielding layer, an inner insulation layer and a core wire layer, wherein the aluminum foil layer is wrapped between the outer insulation layer and the shielding layer in a winding state, and the aluminum foil layer is composed of aluminum foil and the material film.

[0004] At present, when processing the aluminum foil layer of the conductor, the wiring harness factory mostly uses the method of manually stripping and cutting along the root of the outer insulation with a utility knife, which has a very low processing efficiency. There is also a method of laser rotary cutting of aluminum foil, but the aluminum foil layer is wrapped around the shielding layer in a superimposed manner. During production and manufacturing, the first and second layers are extended and formed in a 360° spiral. The power of the laser output is consistent, and the energy of the laser can evenly cut the first layer but cannot cut the second layer. If the second layer is to be effectively cut off, the part without the second layer in the winding direction will cut the shielding layer or cut the inner insulation layer through the shielding layer, causing the shielding layer to break or the inner insulation layer to crack. There is a risk that the automated processing of the aluminum foil layer of the conductor will seriously affect the stripping quality. In addition, since the tightness of the aluminum foil wrapping of wires provided by different wire manufacturers is different, the direction of the aluminum foil layer wrapping on the shielding layer is opposite when both ends of the same wire are processed at the same time, which increases the probability that the aluminum foil is difficult to tear off from the wire smoothly. After the tool pressing and cutting technology cuts off the first layer of aluminum foil, there is also a phenomenon of cutting residue at the overlapping wrapping position of the second layer. In automated processing, the aluminum foil that is not completely cut cannot be removed from the wire smoothly, resulting in poor processing and affecting the efficiency of the entire automatic line processing.

[0005] Based on the above problems, it is urgent to develop an electric heating cutting device and cutting method for the aluminum foil layer of the conductor. Summary of the invention

[0055] like Figure 3 to Figure 5As shown, in this embodiment, the structure of the tool assembly 7 is: it includes a tool insulation seat 701 fixedly connected to the claw arm 403 in the multi-petal claw assembly 4, a tool mounting seat 702 is arranged on the top of the tool insulation seat 701, and a blade 703 is assembled inside the tool mounting seat 702; a heating plate 705 is attached to the back end of the blade 703; a wire lead-out hole 704 is opened on the tool mounting seat 702, and the energized heating wire passes through the wire lead-out hole 704 and is electrically connected to the heating plate 705.

[0056] This embodiment provides an electric heating cutting method for the aluminum foil layer of a conductor. The aluminum foil layer of the conductor 9 is processed by the above-mentioned electric heating cutting device for the aluminum foil layer of the conductor. The process is as follows:

[0057] The heating plate 705 in the cutter assembly 7 is powered on and transfers heat to the blade 703;

[0058] The position of the tool assembly 7 in the front-rear direction of the guide wire 9 is adjusted by the front-rear drive assembly 2;

[0059] After the tool assembly 7 reaches the processing position, the claw arm opening and closing driving assembly 6 drives the multiple claw arms 403 on the multi-petal claw assembly 4 to close simultaneously with the wire 9 as the center, and the distance between the blade 703 and the wire 9 is adjusted by the claw arm opening and closing driving assembly 6;

[0060] The rotary drive assembly 5 drives the multi-petal claw body 402 of the multi-petal claw assembly 4 to rotate forward or reversely, so that the tool assembly 7 rotates synchronously with the rotation of the multi-petal claw body 402.

[0061] Specifically, the heating plate 705 of this embodiment is a ceramic heating plate that can be powered. The ceramic heating plate is electrically connected to the heating wire, and the temperature of the ceramic heating plate can be controlled by an external temperature controller.

[0063] In a specific embodiment of the present application, the processing process is as follows: the ceramic heating plate is powered on to heat the blade 703 to form a hot knife, and the hot knife first cuts the aluminum foil and film of the conductor 9 by burning;

[0064] The hot knife continues to process the partially overlapping area of ​​the second layer of the conductor 9. Where the conductor 9 is coated with aluminum foil in the 360° circumferential direction, the hot knife continues to burn off the plastic film with the aluminum foil layer. Where there is no aluminum foil layer, the hot knife contacts the shielding layer, which is a metal layer. When the hot knife contacts the shielding layer, the heat is transferred to the inner insulating layer. The inner insulating layer is high-temperature resistant silicone rubber or cross-linked polyolefin with a heat-resistant temperature of more than 260°. The temperature at which the hot knife burns off the plastic film of the aluminum foil layer is 100°, which is far lower than the temperature resistance requirement of the inner insulating layer.

[0065] The present application utilizes the heated blade 703 to form a hot knife, which completely burns off the layer of the conductor 9 covered with aluminum foil, so that the aluminum foil layer can be smoothly removed from the conductor 9. In automated processing, the alarm shutdown rate of the production line is greatly improved, providing a guarantee for efficient processing; by burning off the aluminum foil layer with a hot knife, the aluminum foil is completely removed during the processing, thereby achieving zero defects in the aluminum foil removal process.

[0067] The above-mentioned embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
