TECHNICAL FIELD

[0002] In today's rapid development of informatization and intelligence, high-speed data transmission has become the core demand in modern communication, electronics, aerospace and other fields. With the popularization of 5G communication, big data center, automatic driving, Internet of Things and other technologies, the data transmission rate is rising, and the performance of the transmission line bundle is facing unprecedented challenges. The structural stability, signal integrity, electromagnetic compatibility (EMC) and other indicators of the existing bend-resistant high-speed transmission line, as a key carrier for signal and energy transmission, directly affect the reliability and efficiency of system operation. However, in the actual production, processing, transportation and installation process, the line bundle is prone to deformation due to external force (such as bending, extrusion, stretching) or environmental changes (such as temperature, humidity), which may cause signal attenuation, crosstalk, reflection and other signal integrity problems during use, and even cause system failure.

[0049] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0050] Reference Figure 1 A bending-resistant high-speed transmission line straightening device includes: a base 100, a turntable 200, and several straightening mechanisms 300. The turntable 200 has a first through hole 230 in the center for the wire harness to pass through. The turntable 200 can be driven to rotate around the wire harness, and the wire harness is driven to pass through the first through hole 230 at a uniform speed. The base 100 is used to mount the turntable 200. Several straightening mechanisms 300 are evenly distributed circumferentially around the first through hole 230. Each straightening mechanism 300 includes: a pressing roller 310 and an elastic component. The axial direction of the pressing roller 310 is perpendicular to the direction of wire harness passage. With an angle of less than 90 degrees, the rolling roller 310 can be driven to rotate along its own generatrix. The spiral combing trajectory of the rolling roller 310 straightens the wire harness. The rolling roller 310 is subjected to dynamic elastic force by the elastic component to squeeze the wire harness. As the turntable 200 rotates, it drives several straightening mechanisms 300 to rotate around the wire harness. Several rolling rollers 310 continuously roll and comb the entire outer circumference surface of the wire harness in a spiral manner. The straightening force in the combing process can quickly and effectively eliminate the internal stress in all directions of the wire core inside the wire harness, and at the same time straighten the wire harness, improving the working efficiency of wire harness straightening.
[0051] It is important to note that, for example Figure 1 As shown, the device base 100 has a circular channel for the wire harness to pass through, and the channel is concentric with the first through hole 230.
[0052] In order for the turntable 200 to rotate, in one specific implementation, such as Figure 5 As shown, the equipment base 100 has a circular channel for the wire harness to pass through. The channel is concentric with the first through hole 230. A first groove 110 is formed around the channel, and the turntable 200 is rotatably installed in the first groove 110 (see...). Figure 1 The base 100 of the equipment is provided with a third drive assembly 700 for driving the turntable 200 to rotate (see...). Figure 6 ).
[0053] More specifically, such as Figure 6 As shown, the third drive assembly 700 includes a driven pulley 710 and a driving pulley 740, both of which are rotatably mounted on the surface of the equipment base 100. The driven pulley 710 has a hollow internal structure. A transmission belt 720 is sleeved between the driving pulley 740 and the driven pulley 710. The transmission belt 720 can be a toothed synchronous belt. The driving pulley 740 and the driven pulley 710 are matched with it and are provided with a tensioning device that acts on the transmission belt 720, through the meshing of the belt teeth with the tooth grooves of the pulley. To transmit power, a third motor 730 is fixedly installed on the surface of the equipment base 100. The output end of the third motor 730 is fixedly installed at the rotation center of the drive pulley 740. The third motor 730 drives the drive pulley 740 to rotate, and then drives the driven pulley 710 to rotate through the transmission belt 720, which in turn drives the turntable 200 to rotate in the first groove 110. This enables multiple straightening mechanisms 300 to rotate around the wire harness and straighten it, thereby improving the coverage of the straightening mechanism 300 in straightening the wire harness.
[0054] In order for the rolling roller 310 to apply a radially elastic shaping force to the wire harness, in one specific embodiment, such as Figure 2 As shown, the elastic component includes: a second bracket 320, a slider 350, and a second shaft 370. Both the slider 350 and the second shaft 370 are slidably connected to the turntable 200, and their sliding direction points to the center of the first through hole 230. An elastic element 360 is provided between the second shaft 370 and the slider 350. The second bracket 320 has a U-shaped structure with the opening facing downward. The rolling roller 310 is rotatably installed in the second bracket, and the axial direction of the rolling roller 310 forms a settable angle (denoted as α) with the axial direction of the wire harness. The first shaft 330 is fixedly installed on the surface of the second bracket 320. The slider 350 is rotatably connected to the first shaft 330, which facilitates setting the axial direction of the rolling roller 310.
[0055] More specifically, the elastic element 360 is a spring, with its two ends connected to the second shaft 370 and the slider 350 respectively. When no wire harness passes through the equipment, the spring is in a preliminary compressed state. When a wire harness passes through the first through hole 230 for shaping, the spring is further compressed. At this time, the radial force (shaping force) applied by the rolling roller 310 to the wire harness comes from the spring's rebound force, and this shaping force can automatically increase or decrease according to the outer diameter of the wire harness, thus improving the adaptability of the equipment.
[0056] In order to allow both the slider 350 and the second shaft 370 to slide in connection with the turntable 200, in one specific embodiment, such as Figure 4As shown, the surface of the turntable 200 is provided with a plurality of second grooves 210 for mounting the slider 350. The end of the second groove 210 near the center of the first through hole 230 is designated as the proximal end, and the other end is designated as the distal end. The four edges of the turntable 200 are provided with fourth grooves 220. The distal end of each second groove 210 is provided with a circular hole that communicates with the fourth groove 220. The second shaft 370 is slidably mounted in the circular hole.
[0057] It is important to note that the position of the second shaft 370 away from the first through hole 230 can be restricted. In other words, the maximum distance (denoted as a1) between the second shaft 370 and the center of the first through hole 230 can be limited. The larger the value of a1, the smaller the initial compression of the spring, and the smaller the shaping force when the wire harness of the same outer diameter passes through the equipment. Conversely, the smaller the value of a1, the greater the shaping force. By adjusting the value of a1, wire harnesses of the same outer diameter but different materials can be handled, which improves the targeting of the equipment's shaping and helps to enhance the shaping effect.
[0058] If the radial straightening force applied to the wire harness during the straightening process remains constant, the following problems will occur: First, using the large pressure set for the thick wire harness to straighten the thin wire harness will cause the insulation layer of the thin wire harness to crack or be permanently deformed. In severe cases, the internal copper wires will be damaged, changing their electrical characteristics (such as increased resistance). Second, using the small pressure set for the thin wire harness to straighten the thick wire harness will result in insufficient radial force to correct the out-of-roundness of the wire harness and insufficient effective combing force to eliminate internal stress. After straightening, the wire harness may still be bent, or the internal stress may not be eliminated, leading to later springback.
[0059] By setting up a straightening mechanism 300 with elastic straightening force, it can not only apply appropriate straightening force according to the diameter of the wire harness, but also further compress the spring when dealing with stubborn protrusions in the wire harness that are not easy to smooth out (or straighten). The rolling roller 310 rolls over the surface of the protrusion, avoiding equipment overload or damage to the surface of the wire harness. More specifically, a pressure sensor is set to monitor the change in the elastic force of the spring during the straightening process and a warning value is set. When the force of the wire harness on the rolling roller 310 reaches or exceeds this value, the rolling roller 310 can no longer smooth out the protrusion, but rolls over the surface of the protrusion. To prevent the defect from being missed, a corresponding device can be set to mark it and warn the staff, which facilitates further processing of the defect in the wire harness and improves the quality of wire harness straightening.
[0060] In one embodiment, if a1 is set, the spring, in a compressed state, applies a reaction force (denoted as F1) to the second shaft 370 and the slider 350 respectively. At this time, the slider 350 is located at the proximal end. When the wire harness passes through the first through hole 230, the spring can be further compressed according to its outer diameter (denoted as L1). The increased elastic force of the spring is denoted as F2, thus obtaining the radial rolling pressure on the wire harness as F (F=F1+F2). When the outer diameter of the wire harness changes, the magnitude of F increases or decreases simultaneously with L1.
[0061] However, in reality, there are many different types of wire harnesses. Even wire harnesses with the same outer diameter may have different insulation materials. Therefore, the size of F must also take into account F1. However, the size of F1 is related to a1. The smaller a1 is, the larger F1 is.
[0062] In order to control the size of F1 in real time and apply precise correction force, in a specific implementation scheme, such as Figure 3 and Figure 7 As shown, the surface of the turntable 200 is provided with a first drive assembly 400 for adjusting the pre-compression amount of the elastic element 360.
[0063] More specifically, such as Figure 3 As shown, the first driving component 400 includes a plurality of pressure regulating blocks 410. Each pressure regulating block 410 has a bevel 411 on its surface. The plurality of pressure regulating blocks 410 are circumferentially and uniformly slidably installed in the fourth groove 220, and the bevel 411 on the surface abuts against the end of the corresponding second shaft 370. The value of a1 can be defined according to the position of the end of the second shaft 370 abutting against the bevel. Therefore, the value of F1 can be determined by simply changing the position of the pressure regulating block 410 in the fourth groove 220.
[0064] In order to synchronously adjust multiple voltage regulating blocks 410, the first drive assembly 400 further includes: a connecting ring 450, a second gear 430, and a first motor 420. The connecting ring 450 is rotatably mounted on the surface of the turntable 200 and is fixedly connected to multiple voltage regulating blocks 410. A first rack 440 with an arc-shaped structure is fixedly mounted on the inner ring surface of the connecting ring 450. The second gear 430 is rotatably mounted on the surface of the turntable 200 and meshes with the first rack 440. The first motor 420 is fixedly mounted on the surface of the turntable 200, and its output end is fixedly connected to the rotation center of the second gear 430. A battery is set to power the first motor 420, and wireless control technology is used to control the start, stop, and output of the first motor 420.
[0065] To ensure that the rotation of the pressing roller 310 (both its own rotation and its rotation around the wire harness) generates a spiral, rolling combing force along the wire harness axis, when a wire harness passes through the first through hole 230, the pressing roller 310 applies a shaping force to the wire harness while rolling on its surface. By setting the pressing roller 310 to form an angle α with the wire harness axis, the rotation of the pressing roller 310 can be decomposed into two components: one is the circumferential rotation component, which rolls and smooths the wire harness surface; the other is the axial (wire harness) spiral component. Due to the presence of the angle, the coverage of the wire harness shaping is increased, and the scratching caused by sliding friction is greatly reduced, thus improving the quality of the shaped wire harness.
[0066] In actual production, the axial angle α of the rolling roller 310 needs to be changed accordingly when dealing with wire harnesses of different outer diameters. The contact area between the rolling roller 310 and the wire harness is an elliptical contact area. The larger the diameter of the wire harness, the longer the length of the contact area (along the wire harness axis). Regarding the setting of the α value:
[0067] First, for thick wire harnesses with long contact areas, a larger axial "rubbing" stroke is required to effectively cover the entire contact area and comb it. A smaller included angle α should be selected. A smaller α angle can generate a relatively small but more suitable axial movement amount for the long contact area when the rolling roller 310 rotates around the wire harness once, so as to achieve uniform and continuous combing. If α is too large, the axial movement will be too fast, resulting in uneven combing.
[0068] Secondly, for fine wire bundles, the contact area is short, and combing can be completed without a large axial movement. A larger included angle α can be selected. A larger α value can generate stronger axial traction and combing force, and efficiently straighten the fine wire bundles.
[0069] However, under the same outer diameter conditions, the value of α is selected based on the rigidity and bending degree of the wire harness (i.e. the difficulty of straightening). For wire harnesses with high rigidity and difficulty in straightening (high bending degree), a greater axial straightening force is needed to overcome their internal stress and "straighten" them. A larger included angle α should be selected because increasing α is the most effective means of enhancing axial force. For soft and easy-to-straight wire harnesses, a smaller included angle α should be selected to improve the efficiency of straightening work.
[0070] To facilitate real-time adjustment of the axial direction of the compaction roller 310 and to form an appropriate included angle α, in a specific implementation scheme, such as... Figure 2 and Figure 4As shown, a first gear 340 is fixedly mounted on the surface of each first shaft 330. A third groove 211 with a circular structure is opened in the second groove 210 to facilitate the radial movement of the first gear 340 following the first shaft 330. The third groove 211 communicates with the first through hole 230. To facilitate the disassembly and assembly of the equipment, the third groove 211 also communicates with the first through hole 230. A plug 240 is provided in the third groove 211 (see...). Figure 4 The first shaft 330 passes through and slides through the outer surface of the block 240. When the alignment mechanism 300 is not working, the first gear 340 abuts against the surface of the block 240 (under the elastic force of the initial compression spring). The first bracket 120 is fixedly installed on the surface of the turntable 200 (see...). Figure 8 The surface of the first bracket 120 is provided with a second drive assembly 500 for simultaneously driving multiple first gears 340 to rotate (see...). Figure 7 The second drive assembly 500 is controlled by a wireless control system, which in turn controls multiple rolling rollers 310 to maintain precise axial alignment for different types of wire harnesses, thus improving the applicability of the equipment for wire harness alignment.
[0071] More specifically, such as Figure 8 and Figure 10 As shown, the second drive assembly 500 includes: multiple toothed spurs 510, multiple first bevel gears 520, second bevel gears 530, and a second motor 540. The multiple toothed spurs 510 mesh with the multiple first bevel gears 540 respectively. While meshing with the first bevel gears 540, the first bevel gears 340 can also maintain radial sliding (following the radial movement of the roller 310). The multiple toothed spurs 510 are all rotatably connected to the first bracket 120. The multiple first bevel gears 520 are respectively fixedly installed at one end of the multiple toothed spurs 510, and their rotation centers coincide (see...). Figure 8 The second bevel gear 530 is rotatably mounted on the surface of the first bracket 120. The second bevel gear 530 has a ring structure and meshes with multiple first bevel gears 520. The second motor 540 is fixedly mounted on the surface of the first bracket 120. At the same time, the second motor 540 is also powered by a battery. The output end of the second motor 540 is fixedly connected to the rotation center of one of the first bevel gears 520.
[0072] In use, the second motor 540 drives the first bevel gear 520 to rotate, which in turn drives the second bevel gear 530 to rotate, and then drives multiple first bevel gears 520 to rotate simultaneously, thereby controlling the meshing of multiple toothed columns 510 with the first gear 340, so as to achieve precise control of the axial direction (the size of the included angle α) of the rolling roller 310.
[0073] In a specific implementation plan, such as Figure 9As shown, protective covers 600 are fixedly installed on both opposite sides of the surface of the equipment base 100 to protect related components and prevent injury to personnel during equipment operation. The protective covers 600 have through holes that are consistent with the first through hole 230 to facilitate the passage of wire harnesses.
[0074] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
