Description

Technical Field

[0001] This invention relates to the field of high-frequency transmission cable technology, and in particular to a process for manufacturing a high-stability phase cable based on graphene-PTFE composite wrapping tape. Background Technology

[0002] Existing technologies often use silver-plated copper flat strips as the wrapping material, lacking layered functional design and failing to meet multiple performance requirements. While silver-plated copper flat strips provide some conductivity, their poor elasticity makes them unsuitable for adapting to deformation during the wrapping process, easily leading to structural instability due to stress concentration. Furthermore, silver-plated copper flat strips have weak adaptability to thermal expansion, easily deforming significantly with temperature changes. Current wrapping processes lack precise control over expansion and overlap areas, making it impossible to promptly address issues of loose bonding caused by improper expansion or overlap. Existing technologies fail to identify the causes of thermal expansion and lack corresponding control measures, resulting in insufficient heat control. Due to the limited material properties, lack of process control, and inadequate post-processing, existing technologies cannot solve problems such as loose wrapping, poor thermal expansion control, and low structural stability.

[0003] Chinese Patent Publication No. CN222952858U discloses a silver-plated copper flat strip integrally wrapped outer conductor for ship cables, including a conductor structure (1) for operation; the outer side of the conductor structure (1) may be covered with a flat strip wrapping structure (2), a nested wrapping structure (3), and a cross wrapping structure (4); the flat strip wrapping structure (2), the nested wrapping structure (3), and the cross wrapping structure (4) are coated with a corrosion-resistant layer (6) and a conductive layer (7); it can be seen that the silver-plated copper flat strip integrally wrapped outer conductor for ship cables has problems such as loose wrapping, insufficient heat control, and bulging and blistering caused by shrinkage after thermal expansion. Summary of the Invention

[0004] Therefore, this invention provides a high-stability phase cable manufacturing process based on graphene-PTFE composite wrapping tape to overcome the problems of insufficient heat control, difficulty in adapting to deformation requirements during the wrapping process, and structural instability caused by stress concentration in the prior art.

[0005] To achieve the above objectives, this invention provides a process for manufacturing a highly stable phase cable based on graphene-PTFE composite wrapping tape, comprising:

[0006] The take-up frame is controlled to pull the body to be wrapped to the corresponding wrapping area;

[0007] The corresponding layer of wrapping tape is respectively delivered to the corresponding wrapping position in the wrapping area to form a high-stability phase test cable. The wrapping tape includes an inner layer wrapping tape, an outer layer wrapping tape, and a middle layer wrapping tape.

[0008] The thickness of several test points of the high-stability phase test cable and the width of the overlapping area of ​​the wrapping tape are obtained respectively, so as to determine the expansion area based on the thickness and the width;

[0009] The method for handling adhesion risks is determined based on the overlap ratio between the overlapping area of ​​the wrapping tape and the expansion area, including adjusting the guide wheel spacing, or adjusting the distance between the guide wheel and the body to be wrapped based on the expansion length of the expansion area of ​​the non-overlapping area, and adjusting the wrapping angle based on the area ratio of the layered expansion area.

[0010] The body to be wrapped is continued to be wrapped in accordance with the aforementioned bonding risk handling method to form a basic high-stability phase cable;

[0011] The basic high-stability phase cable is subjected to plasma surface treatment and staged hot pressing curing in sequence to output the finished high-stability phase cable.

[0012] Furthermore, the expansion region is the largest curved surface region enclosed by the corresponding detection points in the thickness anomaly region of the high-stability phase test cable that meet the preset width condition, wherein,

[0013] The thickness anomaly region is the curved area enclosed by all detection points on the high-stability phase test cable that have a thickness greater than the preset thickness.

[0014] Furthermore, the preset width condition is that the width of the overlapping area of ​​the wrapping tape is less than the preset width.

[0015] Furthermore, adjusting the guide wheel spacing includes:

[0016] Compare the overlap ratio with the preset overlap ratio;

[0017] If the overlap ratio is greater than the preset overlap ratio, it is determined that the bonding risk exceeds the allowable range, and the guide wheel spacing is increased;

[0018] The spacing between the guide wheels is positively correlated with the overlap ratio.

[0019] Furthermore, the overlap ratio is the ratio of the sum of the areas of the expanded regions within the overlapping area of ​​the wrapping tape to the total area of ​​the expanded regions.

[0020] Further, adjusting the distance between the guide wheel and the package to be wrapped based on the expansion length of the expansion region of the non-overlapping region includes,

[0021] If the overlap ratio is less than or equal to the preset overlap ratio, it is determined that the active contraction risk of the wrapping tape does not meet the requirements, and the expansion length of the expansion region in the non-overlapping region is obtained.

[0022] The expansion length of the expansion region is compared with a preset length;

[0023] If the expansion length of the expansion region is greater than the preset length, then reduce the distance between the guide wheel and the package to be wrapped.

[0024] The distance between the guide wheel and the package to be wrapped is negatively correlated with the expansion length of the expansion region.

[0025] Furthermore, adjusting the wrapping angle according to the area ratio of the layered expansion region includes:

[0026] Obtain the total area of ​​the layered expansion region;

[0027] Obtain the total area of ​​the expanded region of the non-overlapping region;

[0028] Compare the area ratio with the preset area ratio;

[0029] If the area ratio is greater than the preset area ratio, the wrapping angle is reduced to increase the overlapping area.

[0030] Furthermore, the wrapping angle is negatively correlated with the area ratio.

[0031] Furthermore, the layered expansion region is the expansion region in the non-overlapping region where the maximum horizontal projected area of ​​the three-dimensional space enclosed by the wrapping tape corresponding to the detection point with a thickness greater than the preset thickness is greater than the horizontal projected area corresponding to the detection point on the wrapping tape.

[0032] Furthermore, the area ratio is the ratio of the total area of ​​the layered expansion region in a unit monitoring area to the total area of ​​the non-overlapping expansion region.

[0033] Compared with the prior art, the beneficial effect of the present invention is that, by setting up several detection points on the high-stability phase test cable to detect the thickness and width of the overlapping area of ​​the wrapping tape, the present invention determines the expansion area. During the wrapping process of the body to be wrapped, the wrapping tape may expand in some locations where heat accumulates after entering the body to be wrapped due to the increase in heat caused by the rotation of the reel and the friction drag between different layers of the wrapping tape as it moves from the corresponding position on the reel to the winding position. This causes errors in the wrapping process. Furthermore, the overlap between the wrapping tapes on the body to be wrapped... If expansion occurs in the overlapping area, the wrapping tape on the opposite side of the traction direction will eventually be covered and pressed down by the next loop during wrapping. The side of the overlapping area that is not pressed down in the covered area is prone to shrinkage in width when the wrapping tape expands. This shrinkage will lead to non-compliance with the bonding requirements, meaning a decrease in the wrapping accuracy and errors in the specific wrapping position. Therefore, by determining the overlap ratio between the overlapping area of ​​the wrapping tape and the expanded area, a bonding risk handling method can be determined to reduce the risk of decreased wrapping accuracy due to the expansion of the wrapping tape.

[0034] Furthermore, the preparation process of the present invention increases the spacing between the guide rollers. When the overlap ratio between the overlapping area and the expansion area of ​​the wrapping tape exceeds the preset overlap ratio, the increased spacing between the guide rollers reduces the impact of the wrapping tape expansion caused by the heat generated by the extra space and friction between adjacent layers during the wrapping process, which leads to the expansion of the wrapping tape and the resulting misalignment of the wrapping position.

[0035] Furthermore, the preparation process described in this invention adjusts the wrapping angle according to the area ratio of the layered expansion region. By reducing the wrapping angle, the risk of slippage of the wrapping tape caused by the layering of the expansion region is reduced, which may lead to layered expansion of the wrapping tape. This could cause the expanded wrapping tape to be squeezed into two layers, significantly reducing the accuracy of the wrapping. Therefore, reducing the wrapping angle can reduce the area of ​​the overlapping region. As the area of ​​the overlapping region becomes smaller, the effect of layered expansion is reduced, further improving the accuracy of the preparation.

[0036] Furthermore, the preparation process described in this invention adjusts the distance between the guide wheel and the package to be wrapped according to the expansion length of the expansion region in the non-overlapping region, thereby reducing the risk of shrinkage of the wrapping tape due to the expansion in the non-overlapping region, which would otherwise reduce the accuracy of the preparation and further improve the accuracy of the preparation.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The diagrams shown are a flowchart, a schematic diagram of the wrapping device structure, a schematic diagram of the layered expansion type region structure, and a flowchart for adjusting the guide wheel spacing, respectively, representing a high-stability phase cable fabrication process based on graphene-PTFE composite wrapping tape according to an embodiment of the present invention. The high-stability phase cable fabrication process based on graphene-PTFE composite wrapping tape according to an embodiment of the present invention includes:

[0047] Step S1: Control the take-up frame 2 to pull the package 1 to be wrapped to the corresponding wrapping area;

[0048] Specifically, the body to be wrapped 1 is the core part that needs to be wrapped by the wrapping tape during the cable manufacturing process. The core part is a copper core or a silver-plated copper core that provides conductivity.

[0049] Specifically, the traction device uses a wheeled traction machine to pull the body to be wrapped 1 to the wrapping area at a controllable speed and tension, maintaining a stable conveying speed during the wrapping process.

[0050] Step S2: The wrapping tape of the corresponding layer is respectively delivered to the corresponding wrapping position of the wrapping area to form a high-stability phase test cable. The wrapping tape includes an inner wrapping tape, an outer wrapping tape, and a middle wrapping tape.

[0051] The wrapping position is a three-dimensional staggered wrapping, with multiple wrapping positions wrapping the body 1 to be wrapped simultaneously. The wrapping order should follow the sequence of inner layer wrapping first, middle layer wrapping second, and outer layer wrapping last, to form a multi-layer composite wrapping structure.

[0052] Step S3: Obtain the thickness of several test points of the high-stability phase test cable and the width of the overlapping area of ​​the wrapping tape, so as to determine the expansion area based on the thickness and the width.

[0053] The expansion region is the largest curved surface region enclosed by the corresponding detection points in the thickness anomaly region of the high-stability phase test cable that meet the preset width condition.

[0054] The thickness anomaly region is the curved area enclosed by all detection points on the high-stability phase test cable that have a thickness greater than the preset thickness.

[0055] The preset width condition is that the width of the overlapping area of ​​the wrapping tape is less than the preset width.

[0056] Specifically, when the thickness of a test point on the high-stability phase test cable is greater than a preset thickness, it indicates that the thickness of that point exceeds the allowable range. When the width of the corresponding test point in the thickness abnormal area on the high-stability phase test cable is less than a preset width, it indicates that the point meets the preset width condition and the thickness is greater than the preset thickness. With an inner wrapping tape thickness of 0.08mm, a middle and outer wrapping tape thickness of 0.06mm, a wrapping speed of 20m / min, a wrapping process temperature of 40℃, and a wrapping body diameter of 2.0mm, the selectable range of the preset thickness is [0.28mm, 0.35mm], and the preferred embodiment of the preset thickness is 0.30mm; the selectable range of the preset width is [1.92mm, 1.97mm], and the preferred embodiment of the preset width is 1.95mm.

[0057] In practice, an ultrasonic detection array is used to obtain the curved area enclosed by all detection points on the high-stability phase test cable that meet the condition of having a thickness greater than the preset thickness. Then, the maximum curved area enclosed by the corresponding detection points in the thickness abnormal area on the high-stability phase test cable that are less than the preset width condition is obtained.

[0058] Step S4: Determine the bonding risk handling method according to the overlap ratio of the overlapping area of ​​the wrapping tape and the expansion area, including adjusting the guide wheel spacing, or adjusting the distance between the guide wheel 3 and the body to be wrapped 1 according to the expansion length of the expansion area of ​​the non-overlapping area, and adjusting the wrapping angle according to the area ratio of the layered expansion area.

[0059] Compare the overlap ratio with the preset overlap ratio;

[0060] If the overlap ratio is greater than the preset overlap ratio, it is determined that the bonding risk exceeds the allowable range, and the guide wheel spacing is increased;

[0061] The spacing between the guide wheels is positively correlated with the overlap ratio.

[0062] The overlap ratio is the ratio of the sum of the areas of the expanded regions within the overlapping area of ​​the wrapping tape to the total area of ​​the expanded regions.

[0063] If the overlap ratio is less than or equal to the preset overlap ratio, it is determined that the active contraction risk of the wrapping tape does not meet the requirements, and the expansion length of the expansion region in the non-overlapping region is obtained.

[0064] The expansion length of the expansion region is compared with a preset length;

[0065] If the expansion length of the expansion region is greater than the preset length, then reduce the distance between the guide wheel 3 and the package 1 to be wrapped;

[0066] The area ratio is the ratio of the total area of ​​the layered expansion region in a unit monitoring area to the total area of ​​the non-overlapping expansion region.

[0067] The distance between the guide wheel 3 and the package 1 to be wrapped is negatively correlated with the expansion length of the expansion region.

[0068] Obtain the total area of ​​the layered expansion region;

[0069] Obtain the total area of ​​the expanded region of the non-overlapping region;

[0070] Compare the area ratio with the preset area ratio;

[0071] If the area ratio is greater than the preset area ratio, the wrapping angle is reduced to increase the overlapping area.

[0072] The layered expansion region is the expansion region in the non-overlapping region where the maximum horizontal projected area of ​​the three-dimensional space enclosed by the wrapping tape corresponding to the detection point with a thickness greater than the preset thickness is greater than the horizontal projected area corresponding to the detection point on the wrapping tape.

[0073] Specifically, when the overlap ratio is greater than the preset overlap ratio, the thermal expansion effect is mainly caused by the adhesion risk; when the overlap ratio is less than or equal to the preset overlap ratio, the thermal expansion effect is mainly caused by the active contraction risk of the wrapping tape. Under the conditions that the inner wrapping tape has a single-layer thickness of 0.08 mm, the middle and outer wrapping tapes have a single-layer thickness of 0.06 mm, the wrapping linear speed is 20 m / min, the wrapping process temperature is 40 °C, the diameter of the object to be wrapped is 2.0 mm, the preset thickness is 0.30 mm, and the preset width is 1.95 mm, the selectable implementation range of the preset overlap ratio is [20%, 30%], and the preferred embodiment of the preset overlap ratio is 25%.

[0074] Specifically, when the difference between the overlap ratio and the preset overlap ratio is within 2%, the guide wheel spacing is increased by 1cm. When the difference between the overlap ratio and the preset overlap ratio exceeds 2%, the guide wheel spacing is increased by 0.1cm for every 1% exceeding the preset overlap ratio. In a specific embodiment, when the overlap ratio is 30%, the preset overlap ratio is 25%, and the current guide wheel spacing is 20cm, the increased guide wheel spacing is 20cm + 1cm + (30 - 25 - 2) ÷ 1 × 0.1 = 21.3cm.

[0075] In practice, when the overlap ratio is less than or equal to the preset overlap ratio, a laser rangefinder is used to obtain the expansion length of the expansion region in the non-overlapping area and compare it with the preset length.

[0076] Specifically, when the expansion length of the expansion region in the non-overlapping area is greater than the preset length, it indicates that the expansion length of the expansion region in the non-overlapping area exceeds the allowable range. Under the conditions that the single-layer thickness of the inner wrapping tape is 0.08 mm, the single-layer thickness of the middle and outer wrapping tapes is 0.06 mm, the wrapping linear speed is 20 m / min, the wrapping process temperature is 40°C, the diameter of the object to be wrapped is 2.0 mm, the preset thickness is 0.30 mm, the preset width is 1.95 mm, and the preset overlap ratio is 25%, the selectable implementation range of the preset length is [1.0 mm, 2.0 mm], and the preferred embodiment of the preset length is 1.5 mm.

[0077] Specifically, when the difference between the expansion length of the expansion region in the non-overlapping region and the preset length is within 0.2mm, the distance between the guide wheel 3 and the package 1 to be wrapped is reduced by 0.1cm. When the difference between the expansion length of the expansion region in the non-overlapping region and the preset length exceeds 0.2mm, the distance between the guide wheel 3 and the package 1 to be wrapped is reduced by 0.01cm for every 0.1mm exceeding the preset length. In a specific embodiment, when the expansion length of the expansion region in the non-overlapping region is 2.0mm, the preset length is 1.5mm, and the current distance between the guide wheel 3 and the package 1 to be wrapped is 5cm, then the reduced distance between the guide wheel 3 and the package 1 to be wrapped is 5cm - 0.1cm - (2.0mm - 1.5mm - 0.2mm) ÷ 0.1mm × 0.01cm = 4.87cm.

[0078] In implementation, a laser rangefinder is used to obtain the cross-sectional area of ​​the maximum cross-section 7 above the surface of the wrapping tape in the non-overlapping region of the three-dimensional expansion region, and the cross-sectional area of ​​the expansion plane region 8 at the bottom of the three-dimensional expansion region on the wrapping tape, to determine the layered expansion region. A 3D laser contour scanner is used to obtain the area of ​​the layered expansion region and the area of ​​the expansion region in the non-overlapping region. The ratio of the total area of ​​the layered expansion region to the total area of ​​the expansion region in the non-overlapping region is compared with a preset area ratio. When the ratio of the total area of ​​the layered expansion region to the total area of ​​the expansion region in the non-overlapping region is greater than the preset area ratio, it indicates that the slippage risk caused by the layered expansion region exceeds the allowable range. With the inner wrapping tape having a single layer thickness of 0.08 mm, the middle and outer wrapping tapes having a single layer thickness of 0.06 mm, the wrapping speed being 20 m / min, the wrapping process temperature being 40 °C, the diameter of the object to be wrapped being 2.0 mm, the preset thickness being 0.30 mm, the preset width being 1.95 mm, the preset overlap ratio being 25%, and the preset length being 1.5 mm, the optional implementation range of the preset area ratio is [10%, 15%], and the preferred embodiment of the preset area ratio is 13%.

[0079] Specifically, when the difference between the area ratio and the preset area ratio is within 2%, the wrapping angle will be reduced by 1°. When the difference between the area ratio and the preset area ratio exceeds 2%, the wrapping angle will be reduced by 0.1° for every 1% exceeding the preset area ratio. In a specific embodiment, when the area ratio is 17%, the preset area ratio is 13%, and the current wrapping angle is 60°, the reduced wrapping angle is 60° - 1° - (17% - 13% - 2%) ÷ 1% × 0.1° = 58.8°.

[0080] Step S5: Continue to wrap the body 1 to be wrapped according to the bonding risk handling method to form a basic high-stability phase cable;

[0081] The wrapping device runs continuously according to the set guide wheel spacing, the distance between the guide wheel 3 and the body 1 to be wrapped, and the wrapping angle, and sequentially wraps the inner layer of highly conductive graphene PTFE tape, the middle layer of graphene PTFE composite shielding tape, and the outer layer of highly elastic modified PTFE tape onto the surface of the body 1 to be wrapped, forming a wrapping structure.

[0082] Specifically, the inner layer tape 4 is a highly conductive graphene / PTFE tape with a graphene content of 8%; the middle layer tape 5 is an embedded graphene / PTFE composite shielding tape; and the outer layer tape 6 is a highly elastic modified PTFE tape with 5% added nano-ceramic particles.

[0083] The core structure of a basic high-stability phase cable relies on the synergistic effect of three layers of wrapping tape: the inner layer provides high conductivity, the middle layer provides shielding, and the outer layer ensures elasticity and resistance to deformation.

[0084] Step S6: The basic high-stability phase cable is subjected to plasma surface treatment and staged hot pressing curing in sequence to output the finished high-stability phase cable.

[0085] In practice, the plasma surface treatment is a chemical modification process performed on the surface of the basic high-stability phase cable to improve interlayer adhesion.

[0086] Specifically, an atmospheric pressure plasma spray gun is used to bombard the surface of the base cable with high-energy particles of plasma, such as argon or oxygen plasma, breaking the chemical bonds on the surface of the wrapping tape, introducing hydroxyl and carboxyl active groups, removing surface impurities, and enhancing the bonding ability of the contact surfaces of each layer of wrapping tape.

[0087] In practice, the staged hot-press curing is a process in which the wrapping tape material is fully fused and shaped by gradient heating and pressure application.

[0088] Specifically, a vertical hot-press curing tower is used to cure for 30 minutes at 80°C and 0.5MPa to eliminate residual gas between layers; and to cure for 60 minutes at 160°C and 2MPa to promote PTFE sintering and graphene network fusion.

[0089] By using gradient temperature control and pressure assistance, tiny gaps inside the base cable are eliminated, enhancing the overall integrity of the three-layer wrapping tape.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
