Description

Technical Field

[0001] This invention belongs to the field of deformation monitoring technology, and in particular relates to a deformation monitoring device for cable production. Background Technology

[0002] During cable production, cables are often deformed. The geometric shape and structural stability of cables directly affect their electrical performance, mechanical performance, and service life. Excessive cable deformation (such as excessive stretching or flattening) can lead to changes in the cross-sectional area of ​​the cable conductor, affecting its current carrying capacity. Insulation damage can cause short circuits. Cables are also prone to breakage during laying or use due to stress concentration at deformed areas. Therefore, it is necessary to conduct deformation monitoring on cables during production to ensure the quality of cable production. For example, a deformation monitoring device for cable production is disclosed in patent publication number CN117329984B.

[0003] During routine storage, cables are prone to natural bending or loosening due to factors such as accumulated weight and improper winding methods. This morphological change not only leads to distortion of geometric parameters such as local outer diameter and curvature of the cable, but also causes significant errors in the circumferential inspection process. When using laser ranging, the offset and sway of the central axis of the bent cable will interfere with the vertical projection of the laser beam and accurate ranging, resulting in drastic data fluctuations. While traditional caliper measurement can quickly obtain diameter values, it has obvious limitations. If the cable is non-uniformly deformed (such as local concavity and convexity), even if the measured diameter is still within the standard range, it cannot accurately reflect the actual deformation of the cable, thus causing misjudgment of quality inspection results and affecting accurate decision-making in production and application. Summary of the Invention

A rotating screw is rotatably connected between the two horizontal plates. A drive motor for driving the rotating screw to rotate is fixedly mounted on the outer wall of one of the horizontal plates. A movable seat is threaded onto the rod wall of the rotating screw. An extension plate is fixedly connected to the side wall of the movable seat. A transmission plate is provided on the lower side of the extension plate. Multiple compensating rods are symmetrically fixedly connected to the lower end of the extension plate. The compensating rods are slidably sleeved with the transmission plate. Multiple compensating springs sleeved on the compensating rods are fixedly connected to the opposite side of the extension plate and the transmission plate. A pressure sensor is fixedly mounted on the lower side of the extension plate. The cable clamping mechanism located on the lower side is fixedly mounted on the front side of the transmission plate.

[0013] In the aforementioned deformation monitoring device for cable production, the cable clamping mechanism includes a clamping ring, two electric push rods are symmetrically fixedly inserted into the side wall of the clamping ring, an arc-shaped clamping plate is fixedly connected to the moving end of the electric push rod, and a torque sensor is installed at the power end of the electric push rod.

[0014] In the aforementioned deformation monitoring device for cable production, the cable diameter detection feedback mechanism includes a transmission rack fixedly connected to the outer wall of the arc-shaped clamping plate. One end of the transmission rack away from the arc-shaped clamping plate extends through and out of the clamping ring. An optical encoder and a reduction gearbox are fixedly mounted on the outer wall of the clamping ring. A transmission gear meshing with the transmission rack is fixedly connected to the input end of the reduction gearbox. The center of the rotating end of the optical encoder is fixedly connected to the output end of the reduction gearbox.

[0015] In the aforementioned deformation monitoring device for cable production, the laser detection mechanism includes a vertical electric slide rail fixedly installed on the side wall of the fixed plate. A positioning ring is fixedly connected to the moving end of the vertical electric slide rail. A circular electric slide rail is fixedly installed on the inner wall of the positioning ring.

[0016] In the aforementioned deformation monitoring device for cable production, the non-conforming detection and counting mechanism includes a counting shell. A synchronous screw is rotatably connected to the inner wall of the counting shell. A synchronous motor for driving the synchronous screw to rotate is fixedly installed on the outer wall of the counting shell. A synchronous plate is threaded onto the rod wall of the synchronous screw. A non-conforming feedback switch is fixedly installed on one side of the inner wall of the counting shell, opposite to the synchronous plate. An adjusting resistance rod parallel to the synchronous screw is also fixedly installed on the inner wall of the counting shell.

[0019] Compared with existing technologies, the advantages of this invention are as follows:

[0020] By using a fixed plate, traction and tension mechanism, and cable clamping mechanism, a constant tension is applied to keep the cable straight. This ensures that the geometric parameters (such as straightness and outer diameter uniformity) measured during testing are under stress-free deformation conditions, avoiding deviations in cable deformation monitoring data caused by bending. It also ensures that the central axis of the cable being tested coincides with the central axis of the testing position, ensuring accurate cable testing.

[0021] With the established cable diameter detection feedback mechanism, traction tension mechanism, and laser detection mechanism, comprehensive deformation detection of the cable can be performed. The tension force and detection speed of the cable can be automatically adjusted based on the cable diameter. The larger the cable diameter, the greater the tension force is set to help the cable better overcome its bending stiffness and keep it straight. The larger the cable diameter, the lower the detection speed is set in the circumferential direction of cable deformation, ensuring detection accuracy.

[0022] By setting up a non-compliance statistical mechanism and a monitoring frequency self-regulation mechanism, the system can automatically count non-compliance tests during cable deformation testing, and promptly issue warnings to staff when non-compliance tests reach a threshold to remind them to take appropriate action. Furthermore, it can automatically adjust the frequency of the next cable sampling test based on the degree of non-compliance in the previous test, making the testing work more timely and accurate.

[0039] The monitoring frequency self-adjustment mechanism 7 is fixedly installed on the side wall of the fixed plate 1. It is used to control the operation of the laser detection mechanism 5 and is electrically connected to the detection failure statistics mechanism 6.

An arc-shaped pressing block 76 corresponding to the position of the start switch 74 is fixedly installed on the lower side of one end of the connecting plate 75.

[0040] The operating principle of the present invention is described as follows: The electric roller conveying assembly 8 drives the cable body 9 to move and convey. When it is necessary to perform sampling deformation detection on the cable body 9, the PLC controller controls the electric roller conveying assembly 8 to pause its operation and simultaneously drives the two cable clamping mechanisms 3 to operate. The electric push rod 32 pushes the arc-shaped clamping plate 33 to move, so that the two arc-shaped clamping plates 33 firmly clamp and fix the cable body 9 until the torque sensors in the two electric push rods 32 both detect the threshold value, indicating that the arc-shaped clamping plate 33 clamps the cable body 9 sufficiently firmly. At this time, the PLC controller controls the electric push rod 32 to stop its operation.

[0041] The PLC controller then controls the action of the traction and tensioning mechanism 2. The drive motor 23 drives the rotating screw 22 to rotate. Through the threaded connection between the rotating screw 22 and the moving seat 24, and the limiting guide effect of the limiting slide rod 210 on the moving seat 24, the moving seat 24 drives the extension plate 25 to move down. The extension plate 25 drives the transmission plate 26 to move down synchronously through the compensation rod 27 and the compensation spring 28, which in turn drives the cable clamping mechanism 3 located on the lower side to move down, thereby stretching the part of the cable body 9 to be tested, so that the cable body 9 remains straight. Due to the action of the cable clamping mechanism 3, the cable body 9 will eventually be located on the central axis of the clamping ring 31 and the positioning ring 52, ensuring accurate detection position. By applying constant tension to keep the cable body 9 straight, it can be ensured that the geometric parameters (such as straightness and outer diameter uniformity) under stress-free deformation state are measured during the test, avoiding data deviation caused by bending in subsequent deformation detection.

[0042] Furthermore, when the cable body 9 is fixed by the cable clamping mechanism 3, the movement of the arc-shaped clamping plate 33 will drive the transmission rack 41 to move synchronously. Through the meshing of the transmission rack 41 and the transmission gear 44, and in conjunction with the reduction gearbox 43, the rotating end of the optical encoder 42 is driven to move synchronously. The optical encoder 42 feeds back its angle change value to the PLC controller. Specifically, when the diameter of the cable body 9 is larger, the moving distance of the arc-shaped clamping plate 33 is relatively smaller, which in turn makes the rotation angle of the optical encoder 42 smaller. The PLC controller controls the pressure sensor. The higher the threshold value set by pressure sensor 29, the greater the traction force required on the cable body 9. Only when pressure sensor 29 reaches the set threshold will the PLC controller control the drive motor 23 to stop, completing the stretching work on the cable body 9. This is because the larger the diameter of the cable body 9, the higher its bending stiffness. The bending stiffness of the cable (its ability to resist bending deformation) is proportional to the fourth power of its diameter (based on the beam bending theory in mechanics of materials, the formula is EI, where E is the elastic modulus and I is the moment of inertia of the cross section). For a circular cross section cable, the moment of inertia I = πd 4 / 64 (d is the diameter). The larger the diameter, the more exponentially I increases, resulting in the cable body 9 having a stronger ability to resist natural bending. It requires a greater tensile force to overcome its bending stiffness and keep it straight.

[0043] After stretching and keeping the detection section of the cable body 9 straight, the PLC controller controls the laser detection mechanism 5 to start working. The laser rangefinder 54 detects the distance between itself and the outer surface of the cable body 9, and judges whether the comparison between the detection result and the standard result is within the allowable error range. The PLC controller automatically adjusts the specific data of the standard result based on the feedback of the diameter of the cable body 9 from the optical encoder 42, so as to realize the rapid detection of cable bodies 9 with different diameters. During the detection, the PLC controller controls the circular electric slide rail 53 to drive the laser rangefinder 54 to move around the circumference of the cable body 9, and performs a comprehensive deformation detection of the cable body 9. After completing the 360-degree circumferential detection of one position of the cable body 9, the PLC controller controls the vertical electric slide rail 51 to move, driving the laser rangefinder 54 to the detection position of the next part of the cable body 9, and performs continuous detection.

[0044] The speed at which the circular electric slide rail 53 drives the laser rangefinder 54 is based on the diameter of the cable body 9 fed back by the optical encoder 42. The larger the diameter of the cable body 9, the slower the PLC controller controls the circular electric slide rail 53 to drive the laser rangefinder 54. The larger the diameter of the cable body 9, the longer its circumference. If the same number of sampling points per unit length (e.g., 1 data point per millimeter) is maintained, the scanning time needs to be extended to ensure sufficient data density. Moreover, the response time of the laser rangefinder 54 (e.g., the time for signal transmission-reflection-reception) is a fixed value. If the moving speed is too fast, the distance between adjacent measurement points will be too large, or even "missed measurements" will occur (e.g., the device has moved to the next position before the laser has completed a measurement). Data distortion is especially likely to occur in areas with large diameters and gentle curvature changes.

[0045] Furthermore, whenever the deformation of a single location of the cable body 9 is found to be non-compliant with the standard during the 360-degree circumferential deformation inspection, the PLC controller directly controls the laser rangefinder 54 to move to the next inspection position to continue the inspection. Simultaneously, the synchronous motor 63 is controlled to work for 3 seconds. The synchronous motor 63 drives the synchronous screw 62 to rotate. Through the threaded connection between the synchronous screw 62 and the synchronous plate 64, the synchronous plate 64 moves within the statistical housing 61 until the number of non-compliant cable bodies 9 reaches the preset threshold. At this time, the synchronous plate 64 will press on the non-compliant feedback switch 65, thereby causing the alarm 11 to sound, reminding the staff that there is a quality problem with the inspected cable body 9, and promptly tracing the source.

[0046] When the failure rate of the cable body 9 is within the allowable value after inspection, the synchronous plate 64 does not press on the failure feedback switch 65. After the entire inspection of the cable body 9 is completed, the PLC controller controls the cable clamping mechanism 3 to release the clamp on the cable body 9, drives the traction tensioning mechanism 2 to reset to the initial position, and controls the reduction motor 73 and the electric roller transfer assembly 8 to continue working. The reduction motor 73 drives the intermediate shaft 72, the connecting plate 75 and the arc-shaped pressing block 76 to move in the trigger housing 71 until the arc-shaped pressing block 76 presses on the start switch 74, indicating that the sampling deformation inspection of the cable body 9 needs to be carried out again. The above actions are repeated for re-inspection.

[0047] Furthermore, based on the number of times the cable body 9 failed the previous inspection, the synchronous plate 64 is driven to move upward. When the number of unqualified positions of the cable body 9's external deformation is greater in the previous inspection, the synchronous plate 64 moves upward relatively further, which in turn causes the adjusting conductive contact 67 to slide a greater distance on the adjusting resistor rod 66, resulting in a smaller resistance value of the adjusting resistor rod 66. The adjusting conductive contact 67 and the adjusting resistor rod 66 are connected in series in the power supply circuit of the geared motor 73. The geared motor 73 is a DC motor, which increases the speed of the geared motor 73, shortens the interval between the pressing action of the arc-shaped pressing block 76 on the start switch 74, and increases the frequency of re-inspection, making the inspection work more timely and accurate. After the start switch 74 is pressed and triggered, the PLC controller will control the synchronous motor 63 to reverse, so that the synchronous plate 64 is reset to the initial position, and the unqualified status of the re-inspection is recorded.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
