Description

Technical Field

[0001] This invention relates to the field of alloy wire strand production equipment technology, and more specifically, to a winding correction device for alloy wire strand. Background Technology

[0002] Alloy wire stranded wire is a wire bundle made of multiple alloy wires twisted together, and it is widely used in power cables, machinery manufacturing, and other fields. During the stranding process, the strength of the strand directly affects the quality and performance of the wire bundle. Traditional stranding equipment typically uses two methods to adjust the stranding state: one is by changing the bow speed, and the other is by adjusting a fixed twist angle.

[0003] In existing technologies, such as the twisted-pair take-up machine disclosed in patent CN103400658A, the twisting angle is manually adjusted by setting a first cable twisting angle adjustment mechanism at the output end of the main shaft component and multiple second cable twisting angle adjustment mechanisms on the twisting bow, thus solving the problem of fixed and unadjustable twisting angles in traditional equipment. However, in actual production, insufficient torsional strength of the stranded wire leads to a loose wire harness structure and reduced tensile strength; while excessive torsional strength results in excessive rigidity of the wire harness, affecting flexibility and service life. Although this device achieves adjustment of the twisting angle through the angle adjustment mechanism, it cannot adjust the torsional torque of a single strand, i.e., it lacks effective control over torsional strength. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a winding correction device for alloy wire strands.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a winding correction device for alloy wire strands, comprising a frame, a frame between two main shafts of the frame, rotating disks fixedly mounted on the main shafts on both sides of the frame, a stranding bow installed between the two rotating disks, and the two ends of the frame rotatably connected to the main shafts; a twisting assembly is provided at both the inlet and outlet ends of the stranding bow, the twisting assembly applying a torsional force to the wire passing through it; and a detection unit configured to correct the torsional strength of the stranded wire by means of the twisting assembly based on the detected torsional torque of the wire.

[0007] According to one embodiment of the present invention, the twisting assembly includes a mounting bracket mounted on a bow and a twisting wheel mounted on the mounting bracket via a bearing. The twisting wheel has an eccentric hole for the wire to pass through, and an end face gear is provided on one end face of the twisting wheel. The device further includes a driving assembly for driving the end face gear to rotate the twisting wheel, thereby correcting the strand strength by applying forward or reverse twisting to the wire.

[0008] According to one embodiment of the present invention, an adjustment groove is provided on the twisting wheel, an adjustment block is slidably installed in the adjustment groove, and the adjustment block is provided with the eccentric hole; the eccentricity of the eccentric hole is adjusted by changing the position of the adjustment block in the adjustment groove.

[0009] According to one embodiment of the present invention, the drive assembly includes a motor and a transmission rod. The rotating disk has a mounting groove, and a support plate is disposed in the mounting groove. The transmission rod is rotatably mounted on the support plate via a fixed seat. One end of the transmission rod is connected to a first bevel gear that meshes with the end face gear. The output end of the motor is connected to a drive gear, and the other end of the transmission rod is connected to a second bevel gear that meshes with the drive gear.

[0010] According to one embodiment of the present invention, the detection unit includes a first detection unit, the first detection unit including a CCD camera, the CCD camera being disposed on a first support plate and aligned with the section of the wire from the first lead wheel to the fourth lead wheel, for acquiring wire images and calculating the angle formed between the strand's own axis and a single wire, so as to determine the torsional strength of the strand based on the size of the angle.

[0011] According to one embodiment of the present invention, the detection unit includes a second detection unit, which includes a first angular velocity sensor disposed on the shaft of the third lead roller and a second angular velocity sensor disposed on the shaft of the take-up roller. The first angular velocity sensor and the second angular velocity sensor are respectively used to acquire the unwinding angular velocity and the take-up angular velocity, and the tension of the stranded wire is indirectly determined by comparing the difference between the two angular velocities.

[0012] According to one embodiment of the present invention, a control unit is further included, which is communicatively connected to the detection unit and the drive assembly respectively; the control unit is configured to: receive an intensity signal fed back by the detection unit, and when the fed-back intensity signal deviates from a preset intensity range of the yarn, generate a control command to adjust the speed and / or direction of the motor of the drive assembly, thereby causing the torsional strength of the yarn to return to the preset range.

[0013] According to one embodiment of the present invention, when the detection unit includes both a first detection unit and a second detection unit, a preset range corresponding to the first detection unit is set as a first interval; a preset range corresponding to the second detection unit is set as a second interval; the control unit is configured to execute the following mechanism: when the detection data of both detection units are within their respective intervals, the current parameters remain unchanged; when the data of only one detection unit exceeds its corresponding interval, the operating parameters of the drive component are adjusted according to the abnormal data; when the data of both detection units exceed their respective intervals, if the twisted wire state indicated by the data is consistent, the two data are combined for adjustment; if the twisted wire state indicated by the data contradicts each other, an alarm is triggered for manual intervention.

[0014] According to one embodiment of the present invention, a plurality of grooves are provided in the circumferential direction of the end face of the rotating disk, and a counterweight is installed in the groove.

[0015] According to one embodiment of the present invention, the drawbar is provided with a clearance hole for meshing transmission between the first bevel gear and the end face gear to avoid interference.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] In this solution, by setting up a winding correction device that includes a twisting component, and a detection unit to monitor the torsional torque of the yarn in real time, real-time detection and closed-loop control of the twisting strength of the stranded yarn are achieved. This effectively solves the technical problem that traditional equipment cannot adjust the tension of the stranded yarn, and significantly improves the quality of the stranded yarn products.

[0018] In this solution, by using a twisting wheel with an eccentric hole and an end-face gear transmission structure in the twisting assembly, active twisting control of the wire in the forward or reverse direction is achieved. This allows the device to adjust the twisting strength of the strand according to actual needs, overcoming the limitation of traditional equipment that can only indirectly affect the state of the strand by adjusting the speed of the bow.

[0019] In this solution, the eccentricity of the eccentric hole is changed by setting a sliding adjustment block on the twisting wheel, so that the equipment can be adapted to the torsional force of the corresponding specification of wire without changing the motor speed. This not only enhances the adaptability to different specifications of wire, but also avoids the problem of insufficient torque caused by the limitation of motor speed. Attached Figure Description

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0040] Please see Figure 1-8 The present invention provides the following technical solutions:

[0041] Example 1, see Figure 1 and Figure 2 A winding and correcting device for alloy wire strands includes a frame 1, a coiled wire bow 2, a frame 3, a guide assembly 4, a wire laying assembly 5, and a winding roller 6. A first spindle 101 and a second spindle 102 are mounted on the frame 1. A first rotating disk 103 is fixed to one end of the first spindle 101, and a second rotating disk 104 is fixed to one end of the second spindle 102. The coiled wire bow 2 is fixedly mounted between the first rotating disk 103 and the second rotating disk 104, and a frame 3 is also provided between the first rotating disk 103 and the second rotating disk 104. The guide assembly 4 and the wire laying assembly 5 are mounted on the frame 3, and both ends of the frame 3 are rotatably connected to the first spindle 101 and the second spindle 102.

[0042] The frame 3 is a cylindrical structure, consisting of a first support plate 301, a second support plate 302, and a fixing rod 303 installed between them. The guide assembly 4 includes a first lead wheel 401 and a plurality of fourth lead wheels 404 mounted on the first support plate 301, as well as a second lead wheel 402 mounted on the first main shaft 101 and a third lead wheel 403 mounted on the second main shaft 102. A take-up roller 6 is installed between the first support plate 301 and the second support plate 302. The cable laying assembly 5 includes a travel track 503 installed between the first support plate 301 and the second support plate 302. A travel mechanism 501 is installed on the moving end of the travel track 503. In addition, a seventh lead wheel 502 is installed on the first support plate 301, and a fifth lead wheel 5011 corresponding to the seventh lead wheel 502 and a sixth lead wheel 5012 corresponding to the take-up roller 6 are installed on the travel mechanism 501.

[0043] See Figure 6The wire 8 enters from the inside of the second spindle 102, passes through the third guide wheel 403 to the twisting assembly 201 on the bow 2, passes through the twisting assembly 201 and multiple guide wheels 202 to reach another twisting assembly 201 on the bow 2, passes through the twisting assembly 201 to the second guide wheel 402, enters from the inside of the first spindle 101 and is led out to the first guide wheel 401, enters the fourth guide wheel 404 from the first guide wheel 401, enters the seventh guide wheel 502 from the fourth guide wheel 404, then enters the fifth guide wheel 5011 from the seventh guide wheel 502, and is wound up by the take-up roller 6 via the sixth guide wheel 5012.

[0044] Both the first spindle 101 and the second spindle 102 are hollow structures. One end of the first spindle 101 is connected to the middle of the first support plate 301. Mounting grooves are provided on both the first spindle 101 and the second spindle 102 near the frame 3. The second lead wheel 402 and the third lead wheel 403 are respectively set in the mounting grooves of the first spindle 101 and the second spindle 102.

[0045] See Figures 3 to 5 The twisting assembly 201 is disposed at the inlet and outlet ends of the bow 2. The twisting assembly 201 includes a mounting bracket 2011 mounted on the arc-shaped inner wall of the bow 2. A twisting wheel 2012 is mounted on the mounting bracket 2011 via bearings. An eccentric hole is formed in the diameter direction of the twisting wheel 2012, and a ceramic sleeve 2016 is installed in the eccentric hole. An end face gear 2013 is mounted on one end face of the twisting wheel 2012. By mounting a drive assembly 7 on the first rotating disk 103 and the second rotating disk 104, the end face gear 2013 drives the twisting wheel 2012 of the twisting assembly 201 to rotate. When the wire 8 passes through the two twisting assemblies 201 of the bow 2, the drive assembly 7 drives the twisting wheel 2012 to rotate, realizing the twisting operation. Twisting in the direction of twisting increases the twist strength, making the wire bundle stiffer; conversely, twisting against the direction of twisting reduces the twist strength, making the wire bundle looser. Therefore, the correction device in this embodiment adjusts the strength of the stranded wire before winding, so that the wire bundle has a moderate stiffness, thereby completing a higher quality winding.

[0046] See Figure 7 and Figure 8The drive assembly 7 includes a motor 701 and a transmission rod 702. The drive assemblies 7 corresponding to the two guide wheels 202 have the same structure. The second rotating disk 104 has a first mounting groove on one side near the frame 3 and a second mounting groove on the other side. A support plate 105 is provided at the opening of the first mounting groove. The transmission rod 702 is rotatably mounted on the support plate 105 via a fixed seat 703. The upper end of the transmission rod 702 is connected to a first bevel gear 7021 that meshes with the end face gear 2013 of the twisting assembly 201. The motor 701 is installed in the second mounting groove. The drive end of the motor 701 extends into the first mounting area and is connected to a drive gear 7011. The lower end of the transmission rod 702 is connected to a second bevel gear 7022 that meshes with the drive gear 7011. The motor 701 is started. The power of the motor 701 is transmitted through the drive gear 7011 and the second bevel gear 7022 to the first bevel gear 7021 via the transmission rod 702, and then the first bevel gear 7021 transmits the power to the twisting wire assembly 201. (See reference...) Figure 9 The drawbar 2 has a clearance hole 203 for avoiding the first bevel gear 7021.

[0047] Furthermore, the transmission ratio between the drive gear 7011 and the second bevel gear 7022 is 1:2, which is a speed-increasing transmission, while the transmission ratio between the first bevel gear 7021 and the end face gear 2013 is 5:1, which is a speed-reducing transmission. This configuration is because the motor 701 outputs a high speed but relatively low torque. By increasing the speed through speed-increasing transmission, the transmission rod 702's speed is first increased, and then the torque of the twisting wheel 2012 is increased through speed-reducing transmission. This ensures that the twisting wheel 2012 has sufficient torque for twisting operations, while preventing slippage between the drive assembly 7 and the end face gear 2013.

[0048] A counterweight is installed on the second rotating disk 104. Multiple grooves are formed in the circumferential direction on the end face of the second rotating disk 104, and the counterweight is installed in the grooves to ensure the smoothness of the second rotating disk 104 during rotation.

[0049] In Example 2, the eccentric hole on the twisting wheel 2012 is fixed in Example 1, indicating that the stranding strength of the two twisting assemblies 201 is the same at the same rotational speed. However, the stranding strength should be different for different threads 8. There are two main factors affecting the stranding strength: the rotational speed of the twisting wheel 2012 and the position of the eccentric hole on the twisting wheel 2012, i.e., the eccentricity of the eccentric hole. Since the twisting wheel 2012 requires sufficient torque, according to the principle of speed reduction and torque increase, if the motor 701 needs to output a large torque, the motor 701 needs to maintain a low rotational speed; otherwise, slippage will occur between the first bevel gear 7021 and the end face gear 2013, and the twisting wheel 2012 will not be able to correct the stranding strength. In the existing technology, a reduction gearbox is usually installed to achieve both the speed and torque of the motor 701. However, the reduction gearbox is large in size and weight and cannot be installed on the rotating second rotating disk 104. Therefore, it is currently difficult to obtain a large torque while changing the speed of the motor 701.

[0050] Based on the above reasons, this embodiment adopts an adjustable eccentric hole structure, that is, an adjustment groove 20121 is opened on the twisting wheel 2012, an adjustment block 2014 is slidably installed in the adjustment groove 20121 along the groove body direction, and then a twisting groove 20141 is opened on the adjustment block 2014 as an eccentric hole, and a ceramic sleeve 2016 is installed in the twisting groove 20141.

[0051] See Figure 3 The adjusting block 2014 moves within the adjusting groove 20121, causing eccentric holes with different eccentricities to appear on the twisting wheel 2012. This allows for flexible adjustment of the twisting strength. For details, please refer to... Figure 4 A fixing plate 2015 is provided in the adjusting groove 20121 of the twisting wheel 2012. The fixing plate 2015 is L-shaped. One side of the adjusting block 2014 is fixedly connected to one arm of the fixing plate 2015. The other arm of the fixing plate 2015 extends to both sides and is fixedly connected to the end face of the twisting wheel 2012. The position of the adjusting block 2014 in the adjusting groove 20121 can be changed by the different positions of the fixing plate 2015 and the end face of the twisting wheel 2012. In order to ensure the stability of the moving of the adjusting block 2014 in the adjusting groove 20121, sliders are provided on the inner walls of both sides of the adjusting groove 20121. Sliding grooves connected to the sliders are opened on both sides of the adjusting block 2014, thereby changing the distance between the twisting groove 20141 and the center of the twisting wheel 2012, that is, changing the eccentricity. The larger the eccentricity, the stronger the torsional effect on the wire 8 during twisting, and the higher the strand strength; the smaller the eccentricity, the weaker the torsional effect and the lower the strand strength. In this way, precise control of the strand strength can be achieved without changing the speed of motor 701, avoiding the trouble of installing a reduction gearbox and adapting to the production needs of different specifications of wire 8.

[0052] Example 3: This example provides a method for correcting the strength of stranded wires by detecting the angle between the stranded wire axis and the single wire 8 to determine and correct the strength of the stranded wires.

[0053] In this embodiment, a CCD camera is fixedly mounted on the first support plate 301 by a bracket. The CCD camera is mounted between the first lead wheel 401 and the fourth lead wheel 404, with the lens vertically downwards and aligned with the wire 8 to ensure that the shooting area covers the complete cross section of the stranded wire.

[0054] The CCD camera is electrically connected to the control unit, which calculates the included angle value by analyzing the captured image. The included angle here is the intensity signal. When the intensity signal deviates from the preset intensity range, the system sends a signal to the control unit, which adjusts the speed of the motor 701 of the drive component 7 or the eccentricity of the twisting component 201 to bring the twisted wire intensity back to the preset range.

[0055] First, images of the axis outline of the thread 8 and the outline of a single thread 8 are captured using a CCD camera. Then, the included angle α between the two is calculated from the images, with the included angle ranging from 0 to 90 degrees. The preset range for the included angle α is 30 to 60 degrees: when the included angle α is between 30 and 60 degrees, the strand strength is moderate and meets the winding requirements; when the included angle is less than 30 degrees, the strand is too loose and lacks strength; when the included angle α is greater than 60 degrees, the strand is too tight and prone to breakage.

[0056] The inspection process of the winding correction device is as follows:

[0057] Before the equipment is put into operation, a section of wire 8 is transferred from the first lead wheel 401 to the fourth lead wheel 404 for testing. During this period, the CCD camera continuously captures images of the wire 8 and transmits them to the control unit, which calculates the included angle value in real time.

[0058] If the included angle α is within 30 to 60 degrees, the control unit does not issue an adjustment signal, and the equipment maintains its current operating state, indicating that the current specification of the wire 8 is well adapted to the current equipment.

[0059] If the included angle α is less than 30 degrees, it indicates that the wire 8 is starting to soften. The control unit controls the motor 701 of the drive assembly 7 to rotate in the forward direction, which is consistent with the direction of the stranding, thereby increasing the stranding strength. Furthermore, if the included angle α is close to 20 degrees, it indicates that the wire 8 is too loosely stranded. The control unit controls the motors 701 of the two drive assemblies 7 to rotate in the forward direction, but the two motors 701 operate at different speeds. One motor 701 rotates at a speed M times that of the other motor 701, where M is a torsion coefficient greater than 1. This allows the stranding strength of the wire 8 to be quickly increased even when it is too loose.

[0060] If the included angle α is greater than 60 degrees, it indicates that the wire 8 is beginning to stiffen. The control unit controls the motor 701 to rotate in the opposite direction to the stranding direction, thereby reducing the stranding strength. Furthermore, if the included angle α is close to 80 degrees, it indicates that the wire 8 is too tightly twisted. The control unit controls the motors 701 of the two drive components 7 to rotate in the opposite direction, but the two motors 701 still operate at different speeds. The speed of one motor 701 is M times that of the other motor 701, where M is a torsional coefficient greater than 1. This allows the stranding strength of the wire 8 to be quickly reduced when it is too tight.

[0061] The coefficient M is related to the material, diameter and number of strands of the processed filament 8. For filament 8 with good ductility and strong toughness, it can withstand a large internal torsional shear force, so a larger M value, such as 1.5 to 2.5, can be selected to produce a stronger torsional effect. For filament 8 with high brittleness or fineness, a smaller M value, such as 1.1 to 1.5, should be selected to prevent single filament breakage or internal structural damage due to excessive torsion.

[0062] Furthermore, to ensure detection accuracy, the control unit uses the average angle α of 5 consecutive frames of images to avoid misadjustment caused by single shooting error. The adjusted twisted wire assembly 201 remains stationary, waiting to be put into production.

[0063] It should be noted that if, during the adjustment process, the motor 701 rotates while the included angle α remains essentially unchanged, it indicates that the eccentricity of the current twisted wire assembly 201 needs to be adjusted.

[0064] Example 4: This example provides another method for correcting stranded wire strength by detecting the difference in angular velocity between the unwinding end and the winding end to determine and correct the stranded wire strength.

[0065] Specifically, a first angular velocity sensor is installed on the shaft of the third lead reel 403, and a second angular velocity sensor is installed on the shaft of the take-up roller 6. Both angular velocity sensors are electrically connected to the control unit. The control unit acquires the angular velocity values ​​of the two sensors in real time and calculates the difference between their angular angular velocities. , ,in The angular velocity of the third lead wheel 403 is... This refers to the angular velocity of the take-up roller 6. The difference in angular velocity here... This refers to the strength signal. When the strength signal deviates from the preset strength range, the system sends a signal to the control unit, which adjusts the speed of the motor 701 of the drive assembly 7 or the eccentricity of the twisting assembly 201 to bring the strand strength back to the preset range.

[0066] In this embodiment, the angular velocity difference The preset range is -5 rad / s to +5 rad / s, and the specific detection process is as follows:

[0067] when Within this range, it indicates that the pay-off and take-up speeds are matched, and the strand strength is moderate; when When the speed is >+5 rad / s, it indicates that the unwinding speed is greater than the winding speed, the strand is in a slack state, and the stranding strength of wire 8 is insufficient; when When the speed is less than -5 rad / s, it indicates that the take-up speed is greater than the let-out speed, the stranded wire is too tight, and there is a risk of breakage.

[0068] The inspection and correction process of the winding correction device is as follows:

[0069] During equipment operation, two angular velocity sensors continuously detect angular velocity and transmit it to the control unit, which then calculates the angular velocity difference in real time. .

[0070] like Within the range of -5 rad / s to +5 rad / s, the control unit does not issue an adjustment signal, and the equipment maintains its current operating state, which also indicates that the current specification of wire 8 is well adapted to the current equipment.

[0071] like >+5 rad / s indicates that the stranded wire is beginning to loosen. The control unit controls the motor 701 of the drive assembly 7 to rotate in the forward direction, which is consistent with the direction of the stranded wire, in order to increase the strength of the stranded wire; furthermore, if If the speed is >+10 rad / s, it indicates that the stranded wire is severely loose. The control unit controls the motors 701 of the two drive components 7 to rotate in the forward direction, and the two motors 701 also run at different speeds. The speed of one motor 701 is N times that of the other motor 701, where N is a torsion coefficient greater than 1, thereby rapidly increasing the strength of the stranded wire.

[0072] like <-5 rad / s indicates that the stranded wire is becoming too tight. The control unit controls the motor 701 to rotate in the opposite direction to the stranding direction to reduce the stranding strength; furthermore, if If the twisted wire is less than -10 rad / s, it indicates that the twisted wire is too tight. The control unit controls the motors 701 of the two drive components 7 to rotate in opposite directions, and the two motors 701 operate at different speeds. One motor 701 rotates at N times the speed of the other motor 701, thereby rapidly reducing the twisted wire strength.

[0073] Similarly, the coefficient N is related to the material, diameter, and number of strands of the processed wire 8. For a wire 8 with good ductility and high toughness, a larger N value can be selected, such as N ranging from 1.5 to 2.0, to obtain an obvious adjustment effect; for a wire 8 with high brittleness or small diameter, a smaller N value needs to be selected, such as N ranging from 1.1 to 1.4, to prevent excessive adjustment.

[0074] To ensure the detection stability, the control unit adopts a moving average filtering algorithm for the angular velocity signal to eliminate misjudgment caused by instantaneous fluctuations. After the adjustment is completed, the system maintains a stable operating state.

[0075] It should be noted that when the system detects continuous abnormal angular velocity differences and the adjustment effect is not good, the control unit will prompt to check the eccentricity setting of the wire twisting component 201.

[0076] Embodiment 5, this embodiment provides another method for correcting the wire twisting strength, and simultaneously adopts the detection methods provided in Embodiment 3 and Embodiment 4.

[0077] Specifically, this embodiment simultaneously includes the CCD camera in Embodiment 3 and the two angular velocity sensors in Embodiment 4. The control unit is electrically connected to the CCD camera, the first angular velocity sensor, and the second angular velocity sensor, and synchronously receives the included angle α and the angular velocity difference Two types of detection signals.

[0078] The control unit internally sets a preset range of the included angle α corresponding to the first detection unit, with its lower limit being α1 and the upper limit being α2, as well as the range of the angular velocity difference corresponding to the second detection unit, with its lower limit being β1 and the upper limit being β2. The control unit reads the wire twisting included angle α calculated by the first detection unit and the angular velocity difference calculated by the second detection unit in real time. Among them, the preset range of the included angle α is 30 to 60 degrees, and the preset range of the angular velocity difference is -5 rad / s to +5 rad / s. The control unit executes the following decision-making process:

[0079] When both α and are within their respective reasonable ranges, it is determined that the wire twisting strength is qualified and no adjustment is made;

[0080] When α is abnormal (α < 30 degrees or α > 60 degrees) while is normal, the driving component 7 is preferentially adjusted according to the value of α;

[0081] When is abnormal ( < -5 rad / s or > +5 rad / s) while α is normal, the driving component 7 is preferentially adjusted according to the value of ;

[0082] When α and When all are abnormal:

[0083] If both indicate the same state (i.e., α < 30 degrees and...), >+5 rad / s, or α>60 degrees and <-5 rad / s), the control unit adjusts the drive component 7 according to the K value.

[0084]

[0085] in, The degree of bias in visual detection, . For the ideal angle, the midpoint of the interval can be taken here, such as... , This represents the interval width.

[0086] To determine the degree of deviation in motion parameter detection, Similarly, For the ideal angular velocity difference, the midpoint of the interval can also be taken here, such as... , This represents the interval width.

[0087] The weighting coefficients and . This determines the relative reliability or importance of visual detection and motion parameter detection in comprehensive decision-making. For example, if CCD camera detection is considered more stable and reliable, the settings can be adjusted accordingly. > If the angular velocity sensor responds faster during high-speed operation, it can be set... > .

[0088] Furthermore, the larger the value of |K|, the further the strand strength deviates from the ideal state, and the greater the correction required. When K>0, it indicates that the strand is too tight, and the control unit will command motor 701 to rotate in the opposite direction of the strand to reduce the strand strength. When K<0, it indicates that the strand is too loose, and the control unit will command motor 701 to rotate in the same direction as the strand to increase the strand strength.

[0089] If the two indicators contradict each other (i.e., α < 30 degrees but...), <-5 rad / s, or α>60 degrees but (>+5 rad / s), the control unit immediately pauses automatic adjustment, triggers the audible and visual alarm, and maintains the current parameters while waiting for operator intervention.

[0090] Furthermore, in this embodiment, when rapid adjustment is required, the control unit can simultaneously implement differential speed control on the motors 701 of the two drive components 7. The selection of coefficient M or N is based on the currently primary detection signal; if the primary signal is α, then M is selected; if the primary signal is α, then N is selected. The signal to be selected is N.

[0091] It should be noted that the decision cycle in this embodiment is 100ms, which ensures that the system can respond to changes in the twisted wire status in a timely manner, while avoiding frequent adjustments due to signal fluctuations.

[0092] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
