Description

Technical Field

[0001] This invention relates to the technical field of automated cable processing equipment, and more specifically, to a cage stranding machine and a cable stranding guidance control method. Background Technology

[0002] A cable cage stranding machine is a core piece of equipment widely used in the cable processing industry. It is mainly used to strand multiple cables into a single cable bundle according to a certain pitch and rules. As the cable industry continues to raise its requirements for the appearance and performance of cable bundles, especially for flat cables or cables with requirements for distinguishing the front and back sides (such as color strips or shielding layers on the front), the consistency of tension and posture during the stranding process has become a key indicator for measuring the quality of the cable.

[0003] However, existing cage winches still have the following significant drawbacks in actual production: First, during high-speed stranding, the cable tension is highly susceptible to fluctuations due to the continuous changes in the amount of remaining cable on each pay-off shaft and the centrifugal force generated by mechanical rotation. Most existing cage stranding machines lack real-time, precise closed-loop monitoring and adjustment mechanisms for tension. When the tension is too low, the cable is prone to loosening, tangling, or skipping; when the tension is too high, it can cause plastic tensile deformation or even breakage of the cable, seriously affecting the structural tightness and electrical performance of the final wire harness.

[0004] Secondly, for flat cables requiring a specific orientation (front and back), traditional equipment easily causes the cables to twist during the laying and stranding process, resulting in inconsistent front and back orientations in the final cable. This not only severely damages the appearance consistency of the cable bundle but may also lead to inconsistent identification of markings or shielding failure. Currently, the industry mainly relies on manual adjustment of the cable orientation during threading or manual intervention to flip the cables during production. This method is not only inefficient and labor-intensive but also cannot meet the demands of high-speed continuous production, making it difficult to fundamentally eliminate the quality risks associated with inconsistent front and back orientations. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cage stranding machine and a cable stranding guidance control method to address the above-mentioned deficiencies of the prior art.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: On one hand, the present invention provides a cage winch, which includes a main shaft and a fixed shaft coaxial with the main shaft and extending outward from one end of the main shaft; The main shaft is driven to rotate by a drive mechanism, and a mounting frame is fixedly mounted on the main shaft. Multiple sets of wire feeding shaft modules are arranged around the main shaft on the mounting frame. A guide monitoring module is provided at one end of the main shaft near the fixed shaft to guide the cable on the wire feeding shaft module to move outward and monitor the current cable tension. The wire feeding shaft module includes a feeding roller and a tension adjustment component to adjust the wire feeding tension of the feeding roller. The fixed shaft is equipped with a visual monitoring module for identifying preset markings on the cable surface to monitor the cable's orientation, a cable straightening module for rotating the cable to face upwards, and a guide module for guiding the straightened cable to move towards the free end of the fixed shaft; the free end of the fixed shaft is also fixed with a gathering head for gathering and twisting multiple cables into a cable bundle. The cage winch also includes a control module; the guide monitoring module, the tension adjustment component, the vision monitoring module, and the cable straightening module are all electrically connected to and controlled by the control module; the control module controls the tension adjustment component to adjust the tension of the feed roller according to the tension feedback information from the guide monitoring module, and controls the cable straightening module to perform a flipping and straightening action on the cable according to the reverse status information fed back by the vision monitoring module.

[0007] The cage winch of the present invention includes a mounting frame comprising two parallel and spaced first mounting plates sleeved on the main shaft; a plurality of partitions are circumferentially arranged between the two first mounting plates; a mounting cavity is formed between the two partitions; and two sets of the wire feeding shaft modules are arranged in the mounting cavity.

[0008] In the cage winch of the present invention, in the two sets of wire feeding shaft modules in the mounting cavity, the two feeding rollers are coaxially arranged; one end of each feeding roller is rotatably connected to the partition plate through a rotating seat, and the other end of each feeding roller can rotate relative to each other through a rotating bearing; the two tension adjustment components are respectively installed on the inner sidewalls of the two partition plates.

[0009] In the cage winch of the present invention, at least one of the two tension adjustment components includes a U-shaped fixing frame fixedly connected to the first mounting plate, a transmission belt driven by the rotating seat, a telescopic spring, and a telescopic cylinder fixed to the outside of the first end of the U-shaped fixing frame; one end of the transmission belt is fixedly connected to the second end of the U-shaped fixing frame, and the other end passes around the rotating seat and is connected to the drive end of the telescopic cylinder through the telescopic spring.

[0010] The cage winch of the present invention includes a groove on the outer surface of the rotating seat for accommodating the transmission belt; a positioning groove is also provided in the groove; and a protrusion along the length of the transmission belt is provided to slide and position itself in cooperation with the positioning groove.

[0011] The cage winch of the present invention includes a guiding monitoring module comprising a second mounting plate fixedly connected to the main shaft; the second mounting plate is circumferentially provided with a plurality of guide wheels corresponding one-to-one with the wire feeding shaft module and for guiding the winding of the cable, and a tension sensor disposed on one side of the guide wheels; the guide wheels are rotatably connected to the second mounting plate; the tension sensor is fixedly connected to the second mounting plate; the cable is within the monitoring range of the tension sensor, and the tension sensor obtains the tension magnitude by detecting the displacement or tension change of the cable.

[0012] The cage winch of the present invention includes a cable straightening module comprising a third mounting plate fixedly connected to the fixed shaft, and a plurality of straightening units circumferentially mounted on the third mounting plate and corresponding one-to-one with the wire feeding shaft module; the straightening unit includes a base, an elastic pressure head assembly, a first straightening block, and a first drive assembly; The base is fixedly installed on the third mounting plate and has a correction channel for the cable to pass through. The left and right side walls of the correction channel are semi-circular arc-shaped side guide surfaces, and the inner bottom surface of the correction channel is a flat surface. The bottom of the base has a groove that is perpendicular to and connected to the correction channel. The elastic pressure head assembly is disposed above the correction channel and is used to apply downward elastic pressure to the cable located in the correction channel, so that the cable remains in a lateral state and lies flat at the bottom of the correction channel when not interfered with. The first guide block is slidably disposed at the lower end of the base along the groove, and has an action part that extends into the correction channel. The upper surface of the action part is a semi-circular bottom guide surface. A gap is provided between the bottom guide surface and the inner top surface of the correction channel, and the height of the gap is not less than the thickness of the transverse cable. The first driving component is connected to the first guide block and is used to drive the first guide block to perform reciprocating linear motion along the groove; When it is detected that the current cable is facing upwards in reverse, the first drive component drives the first guide block to move. The first guide block pushes the cable to move toward any of the side guide surfaces of the correction channel. Under the joint guidance of the side guide surface, the bottom guide surface, and the two arc surfaces on both sides of the cable, the cable flips to a horizontal posture facing upwards.

[0013] The cage winch of the present invention includes two parallel straightening channels on the base; a groove connecting the two straightening channels; the guiding unit further includes a second guiding block and a second driving assembly; the first guiding block and the first driving assembly are disposed at the front end of the base and located on one side of one of the straightening channels; the second guiding block and the second driving assembly are disposed at the rear end of the base and located on one side of the other straightening channel; the elastic pressure head assembly is located between the first guiding block and the second guiding block, and simultaneously applies elastic pressure to the cables in the two straightening channels.

[0014] The cage winch of the present invention includes a collection head comprising a fixed seat fixedly connected to the fixed shaft; the free end of the fixed seat is provided with a plurality of inclined surfaces that converge toward the central axis of the fixed shaft, and the plurality of inclined surfaces surround to form a conical end; each of the inclined surfaces is provided with a limiting block that matches and fits to it; the limiting block is provided with a rotation limiting groove for at least one cable to pass through in a flat state.

[0015] On the other hand, the present invention also provides a cable stranding guidance control method, using a cage stranding machine as described above, wherein the method includes the following steps: S1. The cable is sequentially passed through the pay-off shaft module, guide monitoring module, cable straightening module, visual monitoring module, guide module, and assembly head. During the cable movement, the guide monitoring module acquires the current cable tension in real time and generates tension feedback information, which is transmitted to the control module. The control module compares the current tension value with the preset tension threshold. If the current tension deviates from the preset threshold, the control module outputs an adjustment signal to the corresponding tension adjustment component based on the deviation, dynamically adjusting the braking friction force on the feeding roller to keep the pay-off tension of each cable within a constant range. S2. The visual monitoring module identifies the preset markings on the surface of the cable passing through its detection area in real time, determines whether the current cable is facing up or down, and feeds back the forward and reverse status information to the control module. S3. The control module receives the status information from step S2. If it determines that the current cable is facing up, the control module does not trigger the cable alignment module, and the cable continues to be conveyed in a straight line while maintaining its current posture. If it determines that the current cable is facing down, the control module sends a flip command to the cable alignment module, and the cable alignment module drives the cable to flip, so that the cable changes from facing down to facing up. S4. After being straightened, multiple cables with their front faces facing upwards move smoothly along the axis of the fixed shaft towards its free end under the guidance of the guide module, maintaining their front-facing orientation during the movement. After the multiple cables move to the junction head at the free end of the fixed shaft and converge, they are twisted together to form a wire harness output under the action of the external rotation drive component.

[0016] The cage stranding machine and cable stranding guidance control method provided by this invention have the following detailed beneficial effects: 1. This invention incorporates a guide monitoring module at the spindle end, which can acquire real-time tension changes during cable movement and generate feedback information. Upon receiving the feedback, the control module compares it with a preset threshold and immediately outputs an adjustment signal to the tension adjustment component, dynamically adjusting the braking friction of the feeding rollers. This closed-loop mechanism of "monitoring-comparison-adjustment" ensures that each cable maintains constant tension during high-speed cable feeding, preventing cable loosening, tangling, and skipping caused by insufficient tension, while also preventing tensile deformation or even breakage caused by excessive tension. This guarantees the final wire harness's structural tightness and electrical performance.

[0017] 2. This invention innovatively introduces a visual monitoring module and a cable alignment module. The visual monitoring module accurately determines the current posture of the cable by recognizing preset markings on the cable surface. Once it detects that the reverse side is facing up, the control module controls the cable alignment module to perform a flipping action, forcing the cable to face up. This process is fully automated, requiring no machine downtime or manual intervention, greatly reducing labor costs and ensuring a high degree of uniformity in the posture of multiple cables before twisting, fundamentally eliminating the quality risks of reverse side misalignment.

[0018] 3. The cable feeding module, guide monitoring module, vision monitoring module, cable straightening module, guide module, and assembly head are tightly connected in series on the same rotation axis. This integrated coaxial layout greatly shortens the cable's path from feeding to stranding, allowing the cable to immediately achieve tension setting and attitude correction after feeding, and then directly reach the assembly head under the guidance of the guide module. Due to the seamless connection between processes, secondary twisting and tension attenuation of the cable caused by long-distance transmission or process transitions are effectively avoided, ensuring that the cable's attitude is perfectly locked before entering the assembly head.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0034] Example 1: This invention provides a cage winch, such as Figure 1 As shown, the device includes a main shaft 01 and a fixed shaft 02 coaxial with the main shaft 01 and extending outward from one end of the main shaft 01. The main shaft 01 and the fixed shaft 02 are fixedly connected. When the device is running, a drive mechanism (not shown in the figure) drives the main shaft 01, the fixed shaft 02 and the mounting frame 11 to rotate at high speed to feed the cables, which facilitates the subsequent twisting of multiple cables 20 into a bundle. This drive mechanism is a rotary motor in the prior art.

[0035] A mounting frame 11 is fixedly installed on the main shaft 01; multiple sets of wire feeding shaft modules 12 are arranged around the main shaft 01 in a circumferential direction on the mounting frame 11; a guide monitoring module 13 is provided at one end of the main shaft 01 near the fixed shaft 02 for guiding the cable 20 on the wire feeding shaft module 12 to move outward and monitoring the current cable tension; the wire feeding shaft module 12 includes a feeding roller 121 and a tension adjustment component 122 for adjusting the wire feeding tension of the feeding roller 121.

[0036] The fixed shaft 02 is provided with a visual monitoring module 14 for identifying preset markings on the cable surface to monitor the forward and reverse states of the cable, a cable straightening module 15 for driving the cable to flip so that it faces upward, and a guide module 16 for guiding the straightened cable to move toward the free end of the fixed shaft 02; the free end of the fixed shaft 02 is also fixedly provided with a gathering head 17 for gathering and twisting multiple cables into a cable bundle.

[0037] In this embodiment, cable 20 is a traditional flat cable with a flat cross-section and rounded surfaces on both sides. The front of the cable typically has a color-coded marking strip (or raised ribs, printed characters), while the back does not. The visual monitoring module 14 consists of multiple cameras corresponding to each cable; these cameras are industrial cameras from the prior art. It monitors the cable's orientation by recognizing the color-coded marking strips on the cable surface.

[0038] In this embodiment, the cage winch also includes a control module (not shown in the figure), which adopts a PLC controller or microprocessor in the prior art; the guide monitoring module 13, the tension adjustment component 122, the vision monitoring module 14, and the cable straightening module 15 are all electrically connected to and controlled by the control module; the control module controls the tension adjustment component 122 to adjust the tension of the feed roller 121 according to the tension feedback information of the guide monitoring module 13, and controls the cable straightening module 15 to perform a flipping and straightening action on the cable according to the reverse state information fed back by the vision monitoring module 14.

[0039] In this embodiment, the mounting frame 11 includes two parallel and spaced-apart first mounting plates 111 sleeved on the main shaft 01; a plurality of partitions 112 are circumferentially arranged between the two first mounting plates 111; a mounting cavity 03 is formed between the two partitions 112; and two sets of wire feeding shaft modules 12 are disposed in the mounting cavity 03. The structure of double mounting plates and partitions not only enhances the structural strength of the entire rotating frame and reduces vibration during high-speed rotation, but also independently separates one or two wire feeding shaft modules 12 within their respective mounting cavities 03; effectively avoiding mutual interference and entanglement of more than four cables during high-speed wire feeding.

[0040] In this embodiment, in the two sets of wire feeding shaft modules 12 within the mounting cavity 03, the two feeding rollers 121 are coaxially arranged; one end of each feeding roller 121 is rotatably connected to the partition 112 via a rotating seat 123, and the other end of each feeding roller 121 can rotate relative to each other via a rotating bearing 124; the two tension adjustment components 122 are respectively installed on the inner sidewalls of the two partitions 112. The coaxial double roller design greatly saves the circumferential space of the mounting frame, allowing the equipment to accommodate more wire feeding shaft groups within a limited volume, increasing the core count of the stranded wire harness; simultaneously, the structure with independent support at both ends and relative rotation via a bearing 124 in the middle ensures that the two coils of cable can be fed independently at different speeds and tensions without dragging each other.

[0041] like Figure 1-2As shown, in this embodiment, at least one of the two tension adjustment components 122 includes a U-shaped fixing frame 1221 fixedly connected to the first mounting plate 111, a transmission belt 1222 drivenly connected to the rotating seat 123, a telescopic spring 1223, and a telescopic cylinder 1224 fixed to the outside of the first end of the U-shaped fixing frame 1221; one end of the transmission belt 1222 is fixedly connected to the second end of the U-shaped fixing frame 1221, and the other end passes around the rotating seat 123 and is connected to the drive end of the telescopic cylinder 1224 through the telescopic spring 1223.

[0042] The working principle of the tension adjustment component 122 is as follows: the transmission belt 1222 is similar to a brake band, tightly gripping the outside of the rotating seat 123. When the guide monitoring module 13 detects that the tension is too low (cable loosening), the control module controls the telescopic cylinder 1224 to retract, pulling the telescopic spring 1223 and the transmission belt 1222, increasing the gripping friction of the transmission belt 1222 on the rotating seat 123, thereby increasing the rotational resistance of the feeding roller 121 and improving the wire feeding tension; conversely, the cylinder extends, releasing the friction. The telescopic spring 1223 provides flexible buffering, avoiding rigid impact on the rotating seat 123 when the cylinder moves, ensuring a smooth and stable tension adjustment process, and preventing the cable from breaking due to excessive instantaneous tension.

[0043] In this embodiment, the outer surface of the rotating seat 123 is provided with a groove 1231 for accommodating the transmission belt 1222; a positioning groove 1232 is also provided in the groove 1231; the inner side of the transmission belt 1222 is provided with a protrusion 1225 along its length direction, which cooperates with the positioning groove 1232 for sliding positioning. The groove 1231 restricts the axial movement of the transmission belt, while the cooperation between the protrusion 1225 and the positioning groove 1232 effectively prevents the transmission belt from slipping laterally when it is under tension, ensuring the reliability and durability of the transmission braking of the tension adjustment assembly 122.

[0044] In this embodiment, the guide monitoring module 13 includes a second mounting plate 131 fixedly connected to the main shaft 01; the second mounting plate 131 is circumferentially provided with a plurality of guide wheels 132 corresponding one-to-one with the cable feeding shaft module 12 and for guiding the cable winding, and a tension sensor 133 disposed on one side of the guide wheel 132; the guide wheel 132 is rotatably connected to the second mounting plate 131; the tension sensor 133 is fixedly connected to the second mounting plate 131; the cable is within the monitoring range of the tension sensor 133, and the tension sensor 133 obtains the tension magnitude by detecting the cable displacement or tension change.

[0045] Specifically, after the cable is led out from the pay-off shaft, it passes around the guide wheel 132 and then through the detection end of the tension sensor 133. When the cable tension changes, the force exerted by the cable on the detection end of the tension sensor changes accordingly, or the cable tensioning / slack causes a displacement change in the contact position. The tension sensor 133 converts these physical quantity changes into electrical signals and feeds them back to the control module, forming a closed-loop control. This follow-up monitoring method is highly sensitive and can capture tension fluctuations in the high-speed pay-off process in real time, providing precise control basis for the front-end tension adjustment component 122.

[0046] In this embodiment, as Figure 3 As shown, the cable straightening module 15 includes a third mounting plate 151 fixedly connected to the fixed shaft 02, and a plurality of straightening units 152 circumferentially mounted on the third mounting plate 151 and corresponding one-to-one with the cable feeding shaft module 12; the straightening unit 152 includes a base 1521, an elastic pressure head assembly 1522, a first straightening block 1523 and a first drive assembly 1524; The base 1521 is fixedly installed on the third mounting plate 151; it is provided with a correction channel 1525 for the cable to pass through, the left and right side walls of the correction channel 1525 are semi-circular arc-shaped side guide surfaces A, and the inner bottom surface of the correction channel 1525 is a flat surface; the bottom of the base 1521 is provided with a groove 1526 that is perpendicular to and connected to the correction channel 1525; The elastic pressure head assembly 1522 is disposed above the correction channel 1525 and is used to apply downward elastic pressure to the cable located in the correction channel 1525, so that the cable remains in a lateral state and lies flat at the bottom of the correction channel 1525 when not interfered with. The first guide block 1523 is slidably disposed at the lower end of the base 1521 along the groove 1526, and its top end has an action part that extends into the correction channel 1525. The upper surface of the action part is a semi-circular arc-shaped bottom guide surface B. A gap is provided between the bottom guide surface B and the inner top surface of the correction channel 1525, and the height of the gap is not less than the thickness of the transverse cable. The first driving component 1524 is connected to the first guide block 1523 and is used to drive the first guide block 1523 to reciprocate linearly along the groove 1526; When it is detected that the current cable is facing upwards in the reverse direction, such as Figure 4 As shown, the first drive assembly 1524 drives the first guide block 1523 to move, and the first guide block 1523 pushes the cable to move along any of the side guide surfaces A of the correction channel 1525, such as... Figure 4-9As shown, under the combined guidance of the side guide surface A, the bottom guide surface B, and the two arc surfaces on both sides of the cable itself, the cable flips into a horizontal posture facing upwards.

[0047] The working principle of its guidance is as follows: The two ends of the flat cable are arc-shaped. When the cable enters the correction channel 1525 laterally with the reverse side facing upwards, it is pressed to the bottom by the elastic pressure head assembly 1522. After the visual monitoring module 14 detects the reverse side information of the cable, the control module feeds the reverse side information back to the cable guidance module 15, such as... Figure 4 The diagram illustrates the first stage of cable alignment, with the reverse side of the cable facing upwards. A first drive assembly 1524 (e.g., a cylinder) pushes a first alignment block 1523 to move within a groove 1526. The thrust of the first alignment block 1523 forces the transverse cable to move towards the side guide surface A. Figure 5 As shown, this illustrates the second stage of cable alignment. The outer arc surface of the cable curves upward on the side guide surface A, simultaneously overcoming the upward displacement of the elastic pressure head assembly 1522; during this process, as... Figure 6 As shown, this is the third stage of cable alignment. The curved surface of the cable's end contacts the side guide surface A and slides upward along the semi-circular side guide surface A, forcing the cable to change from a horizontal to a vertical position. At this time, the outer curved surface of the cable faces upward. Figure 7 As shown, this is the fourth stage of cable alignment. As the alignment block continues to advance, supported by the bottom guide surface B and pressed down by the elastic pressure head assembly, the cable flips past the highest point and tilts to the other side; as shown... Figure 8 The image shows the fifth stage of cable alignment. As the alignment block continues to advance, the cable becomes horizontal within the gap, with its front side (marked) facing upwards. Figure 9 As shown, this is the sixth stage of cable alignment. As the alignment block continues to advance, the cable gradually loses the force of the first alignment block. Under the reset pressure of the elastic pressure head assembly 1522, the cable remains horizontally positioned with its front facing upwards on the inner bottom surface of the alignment channel 1525. This mechanism cleverly utilizes the cross-sectional geometry of the cable and the motion interference within the confined space to achieve automatic and precise forced flipping, resulting in a compact structure and reliable operation.

[0048] In this embodiment, the elastic pressure head assembly 1522 includes a pressure block and a spring; the spring always applies a downward pushing force to the pressure block, so that the pressure block can adaptively adjust the clamping force according to the thickness of the cable and the amount of lifting during flipping.

[0049] In this embodiment, the base 1521 is provided with two parallel correction channels 1525; the groove 1526 passes through and connects the two correction channels 1525; the guiding unit 152 further includes a second guiding block and a second driving assembly; the first guiding block 1523 and the first driving assembly 1524 are disposed at the front end of the base 1521 and located on one side of one correction channel 1525; the second guiding block and the second driving assembly are disposed at the rear end of the base 1521 and located on one side of the other correction channel 1525; the elastic pressure head assembly 1522 is located between the first guiding block 1523 and the second guiding block, and simultaneously applies elastic pressure to the cables in the two correction channels 1525.

[0050] By using the staggered arrangement of the first and second guide blocks on both sides, the structure is compact and can independently guide multiple cables at the same time. It also shares the central elastic pressure head assembly 1522, making the overall structure more compact.

[0051] Because both the left and right side walls of the correction channel 1525 are semi-circular arc-shaped side guide surfaces A, the first guide block can reciprocate within the groove under the action of the second drive component, thus achieving a bidirectional alternating flipping anti-torsion function. When the cable is initially facing upwards, the first guide block pushes the cable from the left side guide surface A to flip it. When the cable is facing upwards again, the first guide block pushes the cable from the right side guide surface A to flip it. Because the flipping direction alternates (once clockwise and once counterclockwise), it effectively counteracts the internal torsional stress accumulated by continuous unidirectional flipping of the cable, preventing the cable from undergoing plastic deformation or jamming due to excessive unidirectional torsion, and greatly protecting the physical properties of the cable.

[0052] like Figure 10 As shown, in this embodiment, the collection head 17 includes a fixed seat 171 fixedly connected to the fixed shaft 02; the free end of the fixed seat 171 is provided with a plurality of inclined surfaces C that converge toward the central axis of the fixed shaft 02, and the plurality of inclined surfaces C surround to form a conical end; each of the inclined surfaces C is provided with a limiting block 172 that matches and fits to it; the limiting block 172 is provided with a rotation groove 173 for at least one cable to pass through in a flat state.

[0053] Its working principle is as follows: Although the cable after being flipped and corrected by the guiding module 15 is facing upwards, it is very prone to spin-back before stranding. The inclined surface C of the tapered end plays a spatial guiding role, smoothly converging multiple circumferentially distributed cables onto the central axis. More importantly, the height of the rotation limiting groove 173 on the limiting block 172 is adapted to the thickness of the flat cable. When the cable passes through the rotation limiting groove 173, it is rigidly restricted and cannot deflect or twist, thus ensuring that the cable always maintains a perfect "face-up" posture when entering the final stranding point. This completely eliminates the quality defect of the cable being cross-sided after cabling and greatly improves the finished product qualification rate of the wire harness.

[0054] Example 2: The present invention also provides a cable stranding guidance control method, using the cage strander as described in Example 1, wherein the method includes the following steps: S1. Pass the cable sequentially through the cable feeding module, guide monitoring module, visual monitoring module, cable straightening module, guide module, and assembly head; During the cable movement and laying process, the tension sensor of the guide monitoring module detects the displacement or tension changes generated when the cable passes around the guide wheel in real time, so as to obtain the current tension of the cable and generate tension feedback information, which is transmitted to the control module. The control module compares the current tension value with the preset tension threshold. If the current tension deviates from the preset threshold, the control module outputs an adjustment signal to the corresponding tension adjustment component according to the deviation, controls the telescopic cylinder to move, and dynamically adjusts the braking friction force on the rotating seat of the feeding roller through the cooperation of the transmission belt and telescopic spring, thereby realizing closed-loop flexible control of the laying tension, so that the laying tension of each cable is always maintained within a constant range, effectively avoiding the cable from loosening and tangling due to insufficient tension or the cable from stretching, deformation or even breakage due to excessive tension. S2. The visual monitoring module acquires images of the cable surface passing through its detection area in real time, identifies preset markings on the cable surface such as color bars, and determines whether the cable is facing up or down, and feeds back the forward and reverse status information to the control module. Since the visual monitoring module is installed on a stationary fixed axis, it can stably and clearly capture the surface posture of high-speed moving cables, ensuring the accuracy of recognition. S3. The control module receives the status information from step S2. If it determines that the current cable is facing upwards, the control module does not trigger the cable straightening module. The cable continues to be conveyed in a straight line under the downward pressure of the elastic pressure head assembly, maintaining its current lateral posture. If it determines that the current cable is facing downwards, the control module sends a flipping command to the cable straightening module. The drive component moves the straightening block along the slide groove into the straightening channel. Since the gap between the bottom guide surface of the straightening block and the top surface of the straightening channel allows the lateral cable to pass through, the cable is pushed by the straightening block and forced to overcome the pressure of the elastic pressure head assembly to move upwards. It slides along the side guide surface on both sides of the cable's arc surface, forcing the cable to change from a lateral to a vertical state. As the straightening block continues to advance, the cable flips past the highest point and tilts to the other side under the support of the bottom guide surface and the downward pressure of the elastic pressure head assembly, completing a 180-degree flip and changing from a downward-facing to a forward-facing lateral posture. After the flip is completed, the first straightening block exits the straightening channel, and the elastic pressure head assembly presses the cable back into place on the inner bottom surface of the straightening channel. S4. After being guided, multiple cables with their front faces facing upwards move smoothly along the axis of the fixed shaft towards its free end under the guidance of the guide module, and maintain their front-facing posture during the movement. The multiple cables move to the collection head at the free end of the fixed shaft, smoothly converge along the inclined surface on the fixed seat, and pass through the rotation limit groove on the limit block. The rotation limiting slot provides rigid constraint to the flat cable, completely preventing the cable from spinning before final stranding. This ensures that multiple cables enter the stranding area with their heads facing upwards, and are finally stranded under the action of the external rotation drive component to form a wire harness output with a consistent appearance and stable structure, which greatly improves the quality and pass rate of cabling.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
