Abstract
Description
Technical Field

Especially in scenarios of multi-channel and same-frequency transmission, the shielding effect of signal cables directly affects the quality and stability of signals. To meet this demand, the design of signal cables has gradually changed to a method of separately shielding sub-cables, that is, to the form of composite shielded cables.

[0030] Through the above drawings, specific embodiments of this application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments
[0031] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.
[0032] Based on the description of the stranding production process of the existing composite shielded cable in the background art, it can be known that in the prior art, the stranding production process of the composite shielded cable requires first passing through a shielding process to longitudinally wrap the shielding tape around the core, and then putting the core after the longitudinal wrapping of the shielding tape into a cage strander for stranding production, thereby completing the stranding production of the composite shielded cable. However, in this production method, the shielding process and the stranding process must be carried out sequentially, which increases the waiting time between production processes, and the two processes carried out separately may lead to inconsistencies in the shielding layer and the stranding layer of the cable in different batches, affecting the quality of the composite shielded cable.
[0033] In view of the above problems, the inventor found in the process of studying the production process of the composite shielded cable that the separation treatment of the shielding process and the stranding process in the prior art not only increases the production time and cost, but also may lead to instability of the shielding effect of the cable. Therefore, a new technical solution is needed to optimize the production process, reduce the waiting time between processes, and ensure the stability and consistency of the shielding layer and the stranding layer. Based on this, on the basis of in-depth analysis and research of the above technical problems, the inventor proposed an innovative technical solution, that is, by carrying out the shielding tape longitudinal wrapping process and the stranding process simultaneously, and configuring corresponding shielding tape placement members and core placement members in the shielding tape longitudinal wrapping process to ensure the high efficiency of the core longitudinal wrapping process, and injecting glue into the core continuously without interruption after the core longitudinal wrapping, realizing the synchronization of the production process. Through this synchronized operation, the problem of process separation in the prior art can be effectively solved, reducing the inconsistencies and errors in the production process, thereby greatly improving the quality and production efficiency of the composite shielded cable.
[0034] The following will specifically describe the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application in conjunction with the accompanying drawings.
[0035] Figure 1 It is a schematic structural diagram of a stranding device for a composite shielded cable provided by an embodiment of the present application. As Figure 1 shown, the stranding device 100 for the composite shielded cable includes:
[0036] A first rotating table 101, a second rotating table 102, a stranding table, and a driving member 103;
[0037] The first rotating table 101 and the second rotating table 102 are sequentially and spacedly sleeved on the rotating shaft of the driving member 103.
[0038] Among them, the first rotating table 101 and the second rotating table 102 refer to a rotating component in the stranding device 100 of the composite shielded cable, and their main function is to accommodate and drive multiple groups of components placed thereon to rotate.
[0039] The driving member 103 may refer to a motor. The rotating shaft of the driving member 103 is a core component of the driving member 103. The rotating shaft generates mechanical motion through rotation, thereby driving the synchronous operation of each component on the rotating shaft.
[0040] In addition, the first rotating table 101 and the second rotating table 102 can respectively carry different functions through the way of spaced installation. Specifically, the first rotating table 101 is used to fix and rotate the core 1061 and the shielding tape 1051. The shielding tape 1051 can be a copper tape, an aluminum tape, etc. The second rotating table 102 further guides the above-mentioned core 1061 and shielding tape 1051, and shapes and processes them before they enter the next stranding operation. At the same time, the design of spaced installation not only avoids the interference of each functional area, but also provides sufficient operating space for subsequent process treatment.
[0041] Figure 2 Another structural schematic diagram of the stranding device of the composite shielded cable provided by the embodiment of the present application. As Figure 2 shown, the first rotating table 101 is provided with multiple groups of components, and each group of components is used to place the shielding tape 1051 and the core 1061.
[0042] Optionally, the first rotating table 101 includes a core sub-rotating table 1012 and a shielding tape sub-rotating table 1011. Each group of components includes a shielding tape sub-component 105 and a core sub-component 106. The shielding tape sub-component 105 is arranged on one side of the shielding tape sub-rotating table 1011 close to the second rotating table 102, and the core sub-component 106 is arranged on one side of the core sub-rotating table 1012 close to the second rotating table 102.
[0043] Among them, the first rotating table 101 is mainly composed of two independent but cooperative sub-rotating tables, mainly including a core sub-rotating table 1012 and a shielding tape sub-rotating table 1011; the design of the core sub-rotating table 1012 is to accommodate and rotate the core 1061 placed in the core placement member 106. The core sub-rotating table 1012 realizes rotation through a rotating shaft connected to the driving member 103. During operation, the core sub-rotating table 1012 drives the core placement member 106 and the core 1061 inside it to rotate synchronously; secondly, in order to ensure the accurate positioning of the core 1061 and prevent it from shifting during rotation, multiple guiding structures are designed on the core sub-rotating table 1012. These guiding structures can be circular or other suitable-shaped grooves that can firmly accommodate the core 1061; in addition, the core sub-rotating table 1012 is arranged relative to the shielding tape sub-rotating table 1011 and is close to the second rotating table 102, so that after the core 1061 is preliminarily processed, it can directly enter the second rotating table 102 for further processing. This can effectively reduce the vibration and swing of the core 1061 during transmission, ensure the stability of the core 1061 during rotation, and improve the quality of the stranded cable.
[0044] The shielding tape sub-rotating table 1011 is mainly used to accommodate and rotate the shielding tape 1051 placed in the shielding tape placement member 105. Similar to the core sub-rotating table 1012, the shielding tape sub-rotating table 1011 also rotates through the same driving shaft, but its structural design pays more attention to the smooth transmission and precise positioning of the shielding tape 1051; secondly, multiple groups of shielding tape placement members 105 are arranged on the shielding tape sub-rotating table 1011. These placement members can firmly fix the shielding tape 1051 and convey the shielding tape 1051 to the second rotating table 102 for further processing through rotation; in addition, the position of the shielding tape sub-rotating table 1011 is arranged relative to the core sub-rotating table 1012 and is close to the second rotating table 102. Such a design enables the shielding tape 1051 to directly enter the second rotating table 102 after rotation and preliminary processing, reducing the transmission distance and time of the shielding tape 1051, ensuring uniform tension of the shielding tape 1051 throughout the production process, and avoiding the situation of breakage or position deviation of the shielding tape 1051 during the stranding process.
[0045] Optionally, the shielding tape placement member 105 is fixed on the shielding tape sub-rotating table 1011 through a first support member, and the core placement member 106 is fixed on the core sub-rotating table 1012 through a second support member.
[0046] For example, the shielding tape placement member 105 is fixed on the side of the shielding tape sub-rotating table 1011 close to the second rotating table 102 through a first support member, and the core placement member 106 is fixed on the side of the core sub-rotating table 1012 close to the second rotating table 102 through a second support member.
[0047] In one implementable manner, to further improve the stability and precision of the shield tape placement member 105 and the core placement member 106 during rotation, the embodiment of the present application provides a design solution for the support member, enabling the placement member to maintain good fixity and smooth operation during rotation. For example, the shield tape placement member 105 and the core placement member 106 are respectively fixed on the rotating table through the first support member and the second support member, effectively avoiding the loosening or displacement problems of the placement member during high-speed rotation, ensuring the precise position of the shield tape 1051 and the core 1061 during the stranding process, reducing unnecessary vibration and friction. In addition, the use of the support member also improves the adaptability of the stranding device 100 of the composite shield cable, enabling it to process cores 1061 and shield tapes 1051 of different specifications and materials to adapt to the production of different types of composite shield cables, significantly improving the production efficiency and product consistency.
[0048] Specifically, the shield tape placement member 105 is fixed on the shield tape rotating table 1011 through the first support member. Among them, the first support member can be made of high-strength alloy material, having good anti-fatigue performance and wear resistance to ensure the stability of the shield tape placement member 105 during high-speed rotation; the first support member is fastened to the surface of the shield tape rotating table 1011 by bolts or welding and is tightly connected to the shield tape placement member 105. For example, the first support member can include a base and an adjustable clamping component. The base is fixed on one side of the shield tape rotating table 1011 close to the second rotating table 102, and the clamping component is used to fasten the shield tape 1051 placement member 105. By adjusting the height and angle of the clamping component, the position and angle of the placement member can be flexibly adjusted, thus ensuring that the shield tape 1051 always remains in a good state during rotation and avoiding stranding quality problems caused by the sliding or displacement of the shield tape 1051.
[0049] The core placement member 106 is fixed on the core rotating table 1012 through the second support member. The design of the second support member is similar to that of the first support member, also made of high-strength material and fixed to the surface of the core rotating table 1012 by bolts or welding. For example, the second support member includes a fixed base and an adjustable clamp, which are used to stabilize the core placement member 106 and allow it to be finely adjusted according to the specifications of the core 1061. The adjustable clamp can be adjusted according to the requirements of different wire diameters to adapt to cores 1061 of different specifications, improving the smoothness of the core 1061 transmission and reducing the damage of the core 1061 during the stranding process.
[0050] The second rotating table 102 is provided with a plurality of first line holes, and the plurality of first line holes correspond to multiple groups of placement members one by one. A forming member 107 is arranged on one side of each first line hole close to the first rotating table 101, and a glue holding member 108 is arranged on one side of the first line hole close to the stranding table.
[0051] Optionally, the forming member 107 is a horn mold.
[0052] Among them, the main function of the forming member 107 is to realize the longitudinal wrapping of the shielding tape 1051 around the wire core 1061, thereby providing a key shielding layer for the production of the composite shielded cable. This forming process ensures that the shielding tape 1051 can be tightly and evenly coated on the surface of the wire core 1061, forming a stable electromagnetic shielding layer, laying a foundation for the subsequent glue injection and stranding processes.
[0053] Specifically, the forming member 107 is designed as a horn mold, and its internal structure is conical, with a wider entrance and a gradually narrowing exit. Among them, the entrance is the side close to the first rotating table 101, and the exit is the side far from the first rotating table 101. The design of the horn mold enables the shielding tape 1051 to gradually fit and wrap around the surface of the wire core 1061 when passing through the forming member 107. The entrance part of the forming member 107 is wide enough to accommodate the loose shielding tape 1051 and the wire core 1061. As the material advances, the forming member 107 gradually narrows, compressing the shielding tape 1051 and tightly coating it on the wire core 1061 to form a longitudinal shielding layer. In addition, the inner wall surface of the forming member 107 is polished to reduce the friction between the shielding tape 1051 and the mold during the forming process, thereby reducing the wear of the shielding tape 1051 and ensuring the consistency of the coating quality. The exit diameter of the forming member 107 is accurately calculated to ensure that the shielding tape 1051 can be coated on the wire core 1061 with appropriate tension without over-compression or slack.
[0054] The stranding table is provided with second line holes, and the shielding tapes 1051 and wire cores 1061 placed in each group of placement members are strung in the corresponding first line holes and second line holes.
[0055] Among them, the first line holes and the second line holes play a key guiding and fixing role in the stranding device 100 of the composite shielded cable, ensuring that the shielding tapes 1051 and wire cores 1061 maintain the correct position and state during the entire production process. At the same time, the coordinated use of the first line holes and the second line holes can also ensure that the shielding tapes 1051 and wire cores 1061 are synchronized during the entire transmission and processing process. It ensures that different materials can be stranded at the same speed and rhythm, avoiding problems of out-of-sync during the stranding process.
[0056] Optionally, the stranding device 100 of the composite shielded cable further includes:
[0057] The third rotating table 104 is provided on the rotating shaft of the driving member 103 and is located between the second rotating table 102 and the stranding table;
[0058] The third rotating table 104 is provided with a plurality of third wire holes, and the plurality of third wire holes correspond to the plurality of first wire holes one by one. The shielding tape 1051 and the wire core 1061 placed by each set of placement members are strung through the corresponding first wire holes, third wire holes, and second wire holes.
[0059] Among them, directly conveying the cable from the second rotating table 102 to the stranding table may cause the stress of the cable during the stranding process to directly act on the second rotating table 102. This stress transmission may affect the working stability of the second rotating table 102, resulting in uneven rotation or cable position deviation, thereby affecting the quality of the cable.
[0060] In order to further optimize the production process of the composite shielded cable and ensure the stability and accuracy during the stranding process, a third rotating table 104 is added between the stranding table and the second rotating table 102 in this application. Its core function is to serve as a transfer platform, enabling the cable that has undergone longitudinal wrapping and injection of the shielding tape 1051 to smoothly transition from the second rotating table 102 to the stranding table; in addition, the design of the third rotating table 104 takes into account the tension and position of the cable, ensuring that the cable always remains on the preset path and position during the transmission process, thereby providing a good foundation for the subsequent stranding process.
[0061] Specifically, the third rotating table 104 is provided on the rotating shaft of the driving member 103 and is located between the second rotating table 102 and the stranding table. It is provided with a plurality of third wire holes, and each third wire hole corresponds to the first wire hole of the second rotating table 102 and the second wire hole of the stranding table one by one. After the shielding tape 1051 and the wire core 1061 complete the longitudinal wrapping and injection of the shielding tape 1051, they enter the third wire hole of the third rotating table 104 from the first wire hole of the second rotating table 102, and then through the rotation of the third rotating table 104, the cable is evenly transmitted into the second wire hole of the stranding table.
[0062] In an implementable manner, the rotation speed and direction of the third rotating table 104 can be independently adjusted from those of the second rotating table 102 and the stranding table. For example, it is achieved through a transmission device of gear meshing. In this way, the speed and direction of the third rotating table 104 can be adjusted according to specific production requirements to adapt to the cable transmission requirements of different materials and structures. Through this method, the third rotating table 104 not only plays a transitional role but also further improves the stability of cable transmission and the accuracy of the stranding process.
[0063] Optionally, the rotation speed and / or rotation direction of the stranding table are different from those of the driving member 103.
[0064] Among them, the stranding table, as a key component in the stranding device 100 of the composite shielded cable, its main function is to precisely strand the cable that has completed the longitudinal wrapping of the shielding tape 1051 and injection of glue to form the final composite shielded cable. Specifically, the stranding table is located on one side of the second rotating table 102 with a glue holding member 108. After the cable that has undergone the longitudinal wrapping of the shielding tape 1051 by the shielding tape rotating table 1011 and the core rotating table 1012 and the injection of glue by the glue holding member 108 in the second rotating table 102 enters the stranding table, the stranding table complex will perform the final stranding operation on these several groups of cables. Among them, the design of the stranding table includes a rotating platform and multiple clamps for fixing the cables, and these clamps can precisely control the stranding angle and stranding density of the cables.
[0065] In an achievable manner, the rotating direction of the stranding table can be opposite to the rotating directions of the driving member 103, the first rotating table 101, and the second rotating table 102, so as to eliminate the stress accumulation during the stranding process, enabling the cable to maintain a straight and stable structure after multiple strandings. For example, when the driving member 103 drives the first rotating table 101 and the second rotating table 102 to rotate clockwise, the stranding table can be set to rotate counterclockwise. Such a design can offset part of the torsion caused by the same-direction rotation during the stranding process, thereby avoiding excessive internal stress in the cable after stranding, which may lead to deformation or performance degradation of the cable.
[0066] The stranding device of the composite shielded cable provided by the embodiments of the present application proposes a design method in which a rotating shaft drives multiple rotating tables to rotate together, which can ensure that the shielding tape 1051 and the core 1061 are synchronized throughout the production process, avoiding out-of-sync situations in different links, greatly improving the quality of cable production, and reducing possible production errors. At the same time, since all the rotating tables are driven by the same rotating shaft, the entire production process is more simplified and efficient, greatly improving the production efficiency. In addition, the stranding device 100 of the composite shielded cable can flexibly adjust the key parameters in the stranding process according to different materials and production requirements, improving the adaptability of the equipment, enabling it to process cables of various specifications, and meeting the needs of different markets.
[0067] Figure 3 It is a schematic structural diagram of the glue holding member in the stranding device of the composite shielded cable provided by the embodiments of the present application. As Figure 3 shown, a first half mold 1081 is provided on one side of the glue holding member 108 close to the first rotating table 101, and a second half mold 1082 is provided on one side of the glue holding member 108 close to the stranding table.
[0068] Specifically, a cavity extending along the movement direction of the wire core 1061 is provided inside the glue holding member 108, and a first half mold 1081 (half mold) and a second half mold 1082 are arranged in the cavity; wherein, the first half mold 1081 is arranged on the side close to the first rotating table 101, the second half mold 1082 is arranged on the side close to the stranding table, there is a gap between the first half mold 1081 and the second half mold 1082, and a glue injection port 109 communicating with it is arranged at the position of the glue holding member 108 corresponding to this gap, that is, the glue injection position is between the first half mold 1081 and the second half mold 1082. Optionally, the inner diameter of the mold of the first half mold 1081 is smaller than that of the second half mold 1082.
[0069] Among them, in order to ensure that the shielding tape 1051 and the wire core 1061 can enter the stranding process in a good state after the glue injection treatment, the first half mold 1081 and the second half mold 1082 are respectively arranged at both ends of the glue holding member 108. The design of these half molds is to control the forming effect of the shielding tape 1051 and the wire core 1061 during the glue injection process, ensure that they maintain a suitable shape and size when passing through the glue holding member 108, so as to provide a stable basis for the subsequent stranding process.
[0070] Specifically, the first half mold 1081 is installed on the side of the glue holding member 108 close to the first rotating table 101. Its main function is to preliminarily form the shielding tape 1051 and the wire core 1061 before the glue injection. The inner diameter of the first half mold 1081 is smaller. The purpose of this design is to compress and position the shielding tape 1051 and the wire core 1061 before the glue injection to ensure that they can be evenly coated with the glue material in the glue holding member 108. For example, the inner diameter of the first half mold 1081 can be 0.3 mm to 0.7 mm larger than the cable. Through the pre - forming of the first half mold 1081, the shielding tape 1051 and the wire core 1061 have been adjusted to a good state when entering the glue holding member 108, which can ensure that the glue material can be evenly distributed on the surface of the shielding tape 1051, avoiding the problem of uneven glue coating caused by the position deviation or looseness of the shielding tape 1051 or the wire core 1061.
[0071] The second half die 1082 is arranged on one side of the glue holding member 108 close to the stranding table. Its inner diameter is relatively larger than that of the first half die 1081. Its main function is to further shape the screened tape 1051 and the wire core 1061 that have been coated with the glue, and ensure that they are output from the glue holding member 108 in a stable shape and enter the stranding table for stranding. For example, the inner diameter of the second half die 1082 can be 0.5 mm to 1.0 mm larger than the cable. Due to the larger inner diameter of the second half die 1082, the screened tape 1051 and the wire core 1061 will be subjected to less compressive force when passing through, which can prevent the cable from damaging the coating due to excessive compression after gluing, and at the same time can provide an appropriate degree of slack for subsequent stranding to avoid over-tightening or twisting during the stranding process.
[0072] Optionally, a glue injection port 109 is also opened at the top of the glue holding member 108.
[0073] Optionally, the glue holding member 108 is also provided with an observation port 110.
[0074] Among them, in order to ensure that the glue holding member 108 can achieve precise glue injection operations during the production process and at the same time facilitate the operator to monitor the glue injection situation in real time, a glue injection port 109 and an observation port 110 are provided on the glue holding member 108. The design of the glue injection port 109 and the observation port 110 aims to improve production efficiency and ensure quality control during the gluing process.
[0075] Specifically, the main function of the glue injection port 109 is to directly inject the liquid glue into the interior of the glue holding member 108, so that the glue can evenly cover the surface of the longitudinally wrapped wire core 1061. Through the glue injection port 109, the operator can control the flow rate and injection speed of the glue, thereby ensuring that the longitudinally wrapped wire core 1061 obtains uniform and appropriate glue coating when passing through the glue holding member 108; the main function of the observation port 110 is to enable the operator to monitor the glue distribution, coating uniformity during the glue injection process, and the running state of the cable inside the glue holding member 108 in real time. Through the observation port 110, the operator can promptly discover abnormal situations during the glue injection process, such as insufficient glue flow rate, uneven gluing, or running deviation of the cable, and make adjustments immediately to ensure the smooth progress of the production process and the quality of the final product.
[0076] In an implementable manner, the glue injection port 109 is usually designed at the central position on the top of the glue container 108 to facilitate the uniform distribution of the glue. The diameter and shape of the glue injection port 109 can be adjusted according to the type and viscosity of the glue used. For example, for high-viscosity glue, the diameter of the glue injection port 109 can be slightly larger to ensure smooth injection of the glue; while for low-viscosity glue, the diameter of the glue injection port 109 can be correspondingly reduced to avoid excessive glue flowing in. In addition, the glue injection port 109 is usually equipped with a regulating valve or a pumping device. The operator can control the injection amount and speed of the glue through the regulating valve to ensure the uniformity and proper amount of glue coating. In addition, the glue injection port 109 can also be connected to an automatic glue injection system to realize a fully automated glue injection process, thereby improving production efficiency and glue coating quality.
[0077] In another implementable manner, the observation port 110 is usually designed on the side of the top of the glue container 108 so that the operator can observe the internal situation from different angles. The observation port 110 is made of a transparent high-temperature resistant material to ensure that a clear view can still be provided in a high-temperature or complex production environment. In addition, the size and position of the observation port 110 should ensure that the operator can clearly see the key parts inside the glue container 108 without affecting the sealing performance of the glue container 108. To avoid splashing of the glue or dust in the production environment from contaminating the observation port 110, the surface of the observation port 110 is usually coated with an anti-fouling coating and is equipped with a detachable protective cover. The protective cover can protect the observation port 110 from damage when not in use. Secondly, the observation port 110 can also be equipped with a lighting device to enhance internal visibility, especially during low-light or night operations. Through this lighting device, the operator can more clearly observe the glue coating situation and the cable operation status inside the glue container 108, thereby better controlling the production process.
