Abstract
Description
Technical Field
[0001] This invention relates to the field of cable manufacturing technology, and in particular to a cable winding flexible shielding manufacturing device. Background Technology
[0002] Copper mesh shielded cable is a type of cable in which a tinned copper wire braided mesh or a bare copper wire braided mesh is wrapped around the core using a manufacturing process. Its shielding performance mainly relies on the outer braided mesh. However, because existing manufacturing equipment uses multiple copper wires to interweave and interlock during the wrapping process, the copper wires are tightly arranged together. As a result, this type of cable is not easy to bend and has poor flexibility. It is difficult to meet the requirements in some scenarios that require frequent bending or movement, highlighting the shortcomings of existing technology. Summary of the Invention
[0003] The purpose of this invention is to provide a cable winding flexible shielding preparation device to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A flexible shielding fabrication device for cable winding includes a support base, a cable dragging mechanism, a support cylinder, an upper rotating cylinder, a lower rotating cylinder, a first support frame, a second support frame, a first hoisting mechanism, a second hoisting mechanism, a bevel gear ring, a mounting base, a third servo motor, and a bevel gear. The support base is equipped with a cable dragging mechanism for dragging the cable and has a fixed vertical support cylinder. The support cylinder is cylindrical and coaxially rotatably connected to the upper and lower rotating cylinders. The upper rotating cylinder has a first support frame fixed to it, and the lower rotating cylinder has a second support frame fixed to it. The first support frame has a first hoisting mechanism installed, and the second support frame has a second hoisting mechanism installed. The No. 1 and No. 2 winches are used to winch the shielded wire. The upper and lower rotating cylinders are respectively rigidly connected to bevel gear rings on the same axis. The support cylinder is radially fixed with a mounting base. The mounting base is rigidly connected to a No. 3 servo motor. The shaft of the No. 3 servo motor is rigidly connected to a bevel gear on the same axis. The No. 3 servo motor has a braking function and is electrically connected to an external electrical control system. When the No. 3 servo motor is energized and rotates, the meshing of the bevel gear and the bevel gear ring enables the upper and lower rotating cylinders to rotate in opposite directions, thereby driving the No. 1 and No. 2 support frames to move circumferentially in opposite directions without interfering with each other.
[0006] Based on the above technical solution, the cable dragging mechanism includes a No. 4 servo motor, a bidirectional lead screw, a slider, a No. 5 servo motor, a rubber roller, and a V-groove. The support base has two rigidly connected No. 4 servo motors at its left end, one at the front and one at the back. The shafts of the two No. 4 servo motors are coaxially rigidly connected to the bidirectional lead screws. The two bidirectional lead screws are rotatably connected to the support base laterally, and their external threads are symmetrically arranged. The two bidirectional lead screws have sliders threaded through their left and right sides. The sliders containing the two bidirectional lead screws are oriented front to back. One of the two corresponding sliders has a No. 5 servo motor fixed laterally along its front to back. The No. 5 servo motor has a braking function. The shafts of the two No. 5 servo motors are rotatably connected to the corresponding sliders of their respective sliders. The shafts of the two No. 5 servo motors are coaxially fixed to rubber rollers, which are symmetrically arranged left to right, and each has an annular V-groove on its outer wall. The No. 4 and No. 5 servo motors are electrically connected to an external electrical control system.
[0007] Based on the above technical solution, the first winch mechanism includes a first servo motor and a first guide component; the second winch mechanism includes a second servo motor, a second guide component, and a third guide component; both the first and second winch mechanisms include winch components, each including a winch; the first support frame is rigidly connected to the first servo motor along the front-rear direction; the second support frame is rigidly connected to the second servo motor along the front-rear direction; the shafts of the first and second servo motors are coaxially rigidly connected to detachable winches; and the first guide component... The No. 1 and No. 3 guide components each include a wire reel that rotates freely relative to the winch. The outer periphery of the middle of the wire reel is provided with a circular concave wire groove. The winch is wound with shielded wire. The shielded wire released by the winch in the No. 1 winch mechanism passes through the wire reel and wire groove of the No. 1 guide component and then passes through the support cylinder from top to bottom. The shielded wire released by the winch in the No. 2 winch mechanism passes through the wire reels and wire grooves of the No. 2 and No. 3 guide components and then passes through the support cylinder from top to bottom. The No. 1 servo motor and the No. 2 servo motor are electrically connected to an external electrical control system.
[0008] Based on the above technical solution, the first guide component includes a first lifting frame and a first pressure sensor; the second guide component includes a second lifting frame and a second pressure sensor; the third guide component includes a third lifting frame and a third pressure sensor; the first support frame is slidably connected to the first lifting frame and rigidly connected to the first pressure sensor; the first pressure sensor is used to detect the downward pressure of the first lifting frame moving downwards; the second support frame is slidably connected to the second and third lifting frames and rigidly connected to the second and third pressure sensors; the second pressure sensor is used to detect the downward pressure of the second lifting frame moving downwards; the third... The pressure sensor is used to detect the downward pressure of the No. 3 lifting frame moving downward. The No. 1, No. 2 and No. 3 pressure sensors are electrically connected to the external electrical control system. The bottom of the No. 1, No. 2 and No. 3 lifting frames are rotatably connected to guide reels. The axis of the guide reel is parallel to the axis of the winch. The guide reels of the No. 2 guide component, the No. 1 guide component, and the No. 3 guide component are arranged in order from near to far from the axis of the support cylinder. The position of the guide reel of the No. 2 guide component is higher than the positions of the guide reels of the No. 1 guide component and the No. 3 guide component.
[0009] Based on the above technical solution, the hoisting component further includes a support shaft, a regular hexagonal prism, a regular hexagonal cylinder, a front limiting plate, a rear limiting plate, limiting bolts, and limiting holes. The rotating shafts of the first and second servo motors are coaxially fixed with circular front limiting plates. Regular hexagonal inserts are coaxially fixed to the rear ends of the two front limiting plates. Support shafts are rotatably connected to the rear parts of the first and second support frames, respectively. The two support shafts are coaxially arranged with the rotating shafts of the first and second servo motors, respectively. Regular hexagonal prisms are coaxially fixed to the front parts of the two support shafts. Regular hexagonal cylinders are axially slidably connected to the two regular hexagonal prisms. The outer surfaces of the two regular hexagonal cylinders... Each wall is radially fixed with a rear limiting plate, and each is radially threaded with a limiting bolt. The two regular hexagonal prisms are radially opened with limiting holes. The limiting bolts can be inserted into the limiting holes. When the limiting holes are inserted into the limiting bolts, the regular hexagonal rod and the regular hexagonal cylinder can be simultaneously inserted into the coaxial parts of the front and rear of the winch to achieve synchronous rotation. When the regular hexagonal rod and the regular hexagonal cylinder are simultaneously inserted into the coaxial parts of the front and rear of the winch, the front limiting plate and the rear limiting plate can respectively abut against the front and rear ends of the winch. The distance between the rear end of the regular hexagonal rod and the front end of the regular hexagonal prism is greater than the radial length of the winch. When the regular hexagonal cylinder moves backward to a certain extent, the regular hexagonal prism can protrude from its front end.
[0010] Based on the above technical solution, the transmission ratio of the bevel gear is the same as that of the two bevel gear rings, and the first support frame and the second support frame are located on the front and rear sides of the support cylinder when they intersect relative to the support cylinder.
[0011] Compared with the prior art, the present invention has the following advantages: When using the present invention, the cable that needs to be wrapped with a shielding layer is introduced into the cable dragging mechanism from top to bottom. The cable dragging mechanism is used to controllably drag the cable. During this process, the No. 3 servo motor is controlled to rotate, thereby driving the upper and lower rotating drums to rotate in opposite directions. The No. 1 and No. 2 winch mechanisms are controlled to work, so that the shielding wires can be released in an orderly manner, so that the two shielding wires are spirally intertwined. Since the amount of copper wire used is reduced, the two copper wires at the same height only have one overlapping contact. Therefore, the overlapping and interweaving between them is not complicated. The wrapped cable is more flexible than the traditional copper mesh shielded cable, and at the same time has a certain shielding performance.
[0012] Because the V-groove squeezes and rubs the cable, it can drag and squeeze the outer shielding layer downwards, which can reduce the gaps between the copper wires outside the cable to a certain extent, thereby improving the signal shielding effect of the cable. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1-5 As shown, a flexible shielding fabrication device for cable winding includes a support base 1, a cable dragging mechanism, a support cylinder 3, an upper rotating cylinder 4, a lower rotating cylinder 5, a first support frame 6, a second support frame 7, a first hoisting mechanism, a second hoisting mechanism, a bevel gear ring 10, a mounting base 11, a third servo motor 12, and a bevel gear 13. The support base 1 is equipped with a cable dragging mechanism for dragging cable B and has a fixed vertical support cylinder 3. The support cylinder 3 is cylindrical and coaxially rotatably connected to the upper rotating cylinder 4 and the lower rotating cylinder 5. The upper rotating cylinder 4 has the first support frame 6 fixed to it, and the lower rotating cylinder 5 has the second support frame 7 fixed to it. The first support frame 6 has a first hoisting mechanism installed, and the second support frame 7 has a second hoisting mechanism installed. The No. 1 and No. 2 winches are used to winch the shielded wire A. The upper rotating cylinder 4 and the lower rotating cylinder 5 are respectively rigidly connected to the bevel gear ring 10 on the same axis. The support cylinder 3 is radially fixed with the mounting base 11. The mounting base 11 is rigidly connected to the No. 3 servo motor 12. The rotating shaft of the No. 3 servo motor 12 is rigidly connected to the bevel gear 13 on the same axis. The No. 3 servo motor 12 has a braking function and is electrically connected to the external electrical control system. When the No. 3 servo motor 12 is powered on and rotates, the meshing of the bevel gear 13 and the bevel gear ring 10 enables the upper rotating cylinder 4 and the lower rotating cylinder 5 to rotate in opposite directions, thereby driving the No. 1 support frame 6 and the No. 2 support frame 7 to move circumferentially in opposite directions without interfering with each other.
[0021] In use, the cable B, which needs to be wrapped with a shielding layer, is introduced from top to bottom into the cable dragging mechanism. The cable dragging mechanism is used to controllably drag the cable. During this process, the No. 3 servo motor 12 is controlled to rotate, thereby driving the upper rotating drum 4 and the lower rotating drum 5 to rotate in opposite directions. The No. 1 winch mechanism and the No. 2 winch mechanism are also controlled to work, so that the shielding cable A can be released in an orderly manner, so that the two shielding cables A are spirally intertwined. Because the amount of copper wire used is reduced, the two copper wires at the same height only have one overlap contact. Therefore, the overlapping and interweaving between them is not complicated. The wrapped cable B is more flexible than traditional copper mesh shielded cables, while also having a certain shielding performance.
[0022] The cable dragging mechanism includes a fourth servo motor 14, a bidirectional lead screw 15, a slider 16, a fifth servo motor 17, a rubber roller 18, and a V-groove 19. The support base 1 has a fourth servo motor 14 rigidly connected to both the front and rear ends of its left side. The shafts of the two fourth servo motors 14 are coaxially rigidly connected to the bidirectional lead screw 15. The two bidirectional lead screws 15 are laterally rotatably connected to the support base 1, and their external threads are symmetrically arranged. The left and right sides of each bidirectional lead screw 15 are threadedly connected to a slider 16. The sliders 16 containing the two bidirectional lead screws 15 are arranged in a... Two corresponding sliders 16 are arranged in a front-to-back manner. One of the sliders 16 is fixed with a No. 5 servo motor 17 in the front-to-back direction. The No. 5 servo motor 17 has a braking function. The rotating shafts of the two No. 5 servo motors 17 are rotatably connected to the corresponding sliders 16. The rotating shafts of the two No. 5 servo motors 17 are coaxially fixed with rubber rollers 18. The two rubber rollers 18 are symmetrically arranged on the left and right sides, and the outer wall of the middle part is provided with annular V-shaped grooves 19. The No. 4 servo motor 14 and the No. 5 servo motor 17 are electrically connected to the external electrical control system.
[0023] Furthermore, by controlling the forward and reverse rotation of the fourth servo motor 14, the left and right distance between the sliders 16 on the left and right sides of the bidirectional lead screw 15 can be adjusted, thereby adjusting the left and right distance between the two V-grooves 19. By squeezing and rubbing the V-grooves 19 with the cable B, cables of different diameters can be dragged. Since the V-grooves 19 squeeze and rub the cable B and drag it, the outer shielding layer can be dragged downward and squeezed, which can reduce the gaps between the copper wires outside the dragged cable to a certain extent, thereby improving the signal shielding effect of the cable B.
[0024] The first winch mechanism includes a first servo motor 20 and a first guide component 21. The second winch mechanism includes a second servo motor 22, a second guide component 23, and a third guide component 24. Both the first and second winch mechanisms include winch components, each including a winch 26. The first support frame 6 is rigidly connected to the first servo motor 20 along the front-rear direction. The second support frame 7 is rigidly connected to the second servo motor 22 along the front-rear direction. The shafts of the first and second servo motors 20 and 22 are coaxially rigidly connected to the detachable winch 26. The first guide component 21, the second guide component 23, and the third guide component 24... Each component 24 includes a wire reel 27 that rotates freely relative to the winch 26. The outer periphery of the middle of the wire reel 27 is provided with a circular concave wire groove 28. The winch 26 is wound with shielded wire A. In the first winch mechanism, the shielded wire A released by the winch 26 passes through the wire reel 27 and wire groove 28 of the first guide component 21 and then passes through the support cylinder 3 from top to bottom. In the second winch mechanism, the shielded wire A released by the winch 26 passes through the wire reel 27 and wire groove 28 of the second guide component 23 and the third guide component 24 and then passes through the support cylinder 3 from top to bottom. The first servo motor 20 and the second servo motor 22 are electrically connected to the external electrical control system.
[0025] By controlling the orderly rotation of servo motor 20 and servo motor 22, the shielded wire A can be released in an orderly manner. Then, in conjunction with the downward-pulled cable B, winding is achieved. The use of wire reel 27 and wire groove 28 enables the control of the position of shielded wire A to ensure accurate winding.
[0026] The first guide component 21 includes a first lifting frame 29 and a first pressure sensor 30; the second guide component 23 includes a second lifting frame 31 and a second pressure sensor 32; the third guide component 24 includes a third lifting frame 33 and a third pressure sensor 34; the first support frame 6 is slidably connected to the first lifting frame 29 and rigidly connected to the first pressure sensor 30; the first pressure sensor 30 is used to detect the downward pressure of the first lifting frame 29 moving downwards; the second support frame 7 is slidably connected to the second lifting frame 31 and the third lifting frame 33 and rigidly connected to the second pressure sensor 32 and the third pressure sensor 34; the second pressure sensor 32 is used to detect the downward pressure of the second lifting frame 31 moving downwards; the third pressure sensor 34 is used to detect the downward pressure of the second lifting frame 31 moving downwards; and the third pressure sensor 34 is used to detect the downward pressure of the second lifting frame 31 moving downwards. The downward pressure of the third lifting frame 33 is detected. The first pressure sensor 30, the second pressure sensor 32, and the third pressure sensor 34 are electrically connected to the external electrical control system. The bottom of the first lifting frame 29, the second lifting frame 31, and the third lifting frame 33 are rotatably connected to the guide reel 27. The axis of the guide reel 27 is parallel to the axis of the winch 26. The guide reel 27 where the second guide component 23 is located, the guide reel 27 where the first guide component 21 is located, and the guide reel 27 where the third guide component 24 is located are arranged from near to far relative to the axis of the support cylinder 3. The position of the guide reel 27 where the second guide component 23 is located is higher than the positions of the guide reel 27 where the first guide component 21 is located and the guide reel 27 where the third guide component 24 is located.
[0027] Furthermore, the pressure sensors 30, 32, and 34 can detect the downward pressure applied to the wire reel 27, lifting frame 29, lifting frame 31, and lifting frame 33 by the shielded wire A as it moves downward toward the support cylinder 3 after passing through the wire grooves 28. This reflects the tension of the shielded wire A and feeds it back to the electrical control system to reasonably control the rotation speed of the servo motors 20 and 22, i.e., to reasonably and dynamically control the release speed of the shielded wire A. This ensures that the shielded wire A is tightly wound without being too tight and causing damage to the shielded wire A or deformation of the cable B. The position of each wire reel 27 ensures that the shielded wire A does not interfere with the cable B when it is wound around the cable.
[0028] The hoisting component also includes a support shaft 35, a regular hexagonal prism 36, a regular hexagonal cylinder 37, a front limiting plate 38, a rear limiting plate 39, a limiting bolt 40, and a limiting hole 41. The rotating shafts of the first servo motor 20 and the second servo motor 22 are coaxially fixed with circular front limiting plates 38. Regular hexagonal inserts 42 are coaxially fixed to the rear ends of the two front limiting plates 38. Support shafts 35 are rotatably connected to the rear parts of the first support frame 6 and the second support frame 7, respectively. The two support shafts 35 are coaxially arranged with the rotating shafts of the first servo motor 20 and the second servo motor 22, respectively. Regular hexagonal prisms 36 are coaxially fixed to the front parts of the two support shafts 35. Regular hexagonal cylinders 37 are axially slidably connected to the two regular hexagonal prisms 36, respectively. The outer walls of the two regular hexagonal cylinders 37 are radially... A rear limiting plate 39 is fixed, and limiting bolts 40 are radially threaded through it. The two regular hexagonal prisms 36 are radially opened with limiting holes 41. The limiting bolts 40 can be inserted into the limiting holes 41. When the limiting holes 41 are inserted into the limiting bolts 40, the regular hexagonal insert rod 42 and the regular hexagonal cylinder 37 can be simultaneously inserted into the coaxial parts of the front and rear of the winch 26 to achieve synchronous rotation. When the regular hexagonal insert rod 42 and the regular hexagonal cylinder 37 are simultaneously inserted into the coaxial parts of the front and rear of the winch 26, the front limiting plate 38 and the rear limiting plate 39 can respectively abut against the front and rear ends of the winch 26. The distance between the rear end of the regular hexagonal insert rod 42 and the front end of the regular hexagonal prism 36 is greater than the radial length of the winch 26. When the regular hexagonal cylinder 37 moves backward to a certain extent, the regular hexagonal prism 36 can protrude from its front end.
[0029] Furthermore, when the shielding wire A wound on the winch 26 is exhausted or needs to be replaced, the connection between the limiting bolt 40 and the limiting hole 41 can be released by manually rotating the limiting bolt 40 with a wrench or other tools. Then, the hexagonal cylinder 37 can be moved backward to disengage it from the winch 26. Then, the winch 26 can be disassembled and replaced with another winch 26. Then, the winch 26 is connected to the hexagonal insert rod 42 and the hexagonal cylinder 37. Then, the connection between the limiting bolt 40 and the limiting hole 41 is restored. The position of the winch 26 is then stabilized and limited by the front limiting plate 38 and the rear limiting plate 39.
[0030] The bevel gear 13 has the same transmission ratio as the two bevel gear rings 10. When the first support frame 6 and the second support frame 7 intersect with the support cylinder 3, they are located on the front and rear sides of the support cylinder 3.
[0031] Furthermore, by setting the positions of the first support frame 6 and the second support frame 7 relative to the support cylinder 3 when they intersect, the positions of the two shielded wires A when they overlap are the front and rear sides of the cable B. This ensures that the wires do not come into contact with the overlapping area as much as possible when they are squeezed by the rubber roller 18, thereby reducing the asymmetry when the cable B is squeezed and dragged, reducing the deformation of the cable B, and ensuring quality.
[0032] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
