The straightness detection module is provided with a straightness eccentricity threshold and a straightness calculation algorithm. The straightness detection component performs the following steps for detecting the straightness of the cable:

[0028] S1: Reduce the pressure of the heating blanket on the cable surface;

[0029] S2: Start the laser distance meter to measure the distance between the cable surface and the card block;

[0030] S3: Based on the collected spacing data, the straightness of the cable after heating and straightening is obtained by using a straightness calculation algorithm, and the straightness obtained by the detection calculation is compared with the straightness eccentricity threshold;

[0031] S4.1: When the detected straightness is within the straightness eccentricity threshold, the reminder module is triggered;

[0032] S4.2: Detecting that the straightness exceeds the straightness eccentricity threshold interval triggers the control system to cyclically heat the heating blanket repeatedly.

[0033] The beneficial effect of this technical solution is that when it is detected that the straightness of the cable does not meet the standard, the cable is heated and straightened for a second time to avoid secondary damage to the cable caused by repeated loading and unloading.

[0034] A method for using an intelligent device for heating and straightening a cable, based on the intelligent device for heating and straightening a cable described in the above technical solution, the method for using the intelligent device is as follows:

[0035] a: Clean the surface of the cable end to be heated;

[0036] b: Rotate the head end movable plate and the end movable plate relative to the mutually hinged support plates to open the fixing device, and place the cable to be heated on the heating blanket in the fixing device;

[0037] c: Insert the pin at the end of the main buckle chain into the slot at the end of the secondary buckle chain. As the pin goes deeper into the slot, the locking plate pops into the plate slot to fix the pin relative to the slot. Turn the rotating self-locking switch on the secondary self-locking plate, pull the pull head along the secondary self-locking plate from the slot to the limit block, wrap the part to be heated in the heating blanket, wrap the sealing strips at both ends, and perform heat preservation and sealing on both ends of the heating cable;

[0038] d: Start the control device, and the pressure sensor on the surface of the heating blanket begins to record the pressure data on the surface, and compares the collected pressure data with the calculated pressure data. The control system controls the winding wheel to tighten and roll the pull rope and the heating blanket to adjust the heating blanket and the fixing device to evenly hold the cable surface;

[0039] e: After adjusting the heating blanket to evenly hold the cable surface, the control system controls the heating blanket to heat the cable surface. The heating temperature is 75℃-80℃ and the heating time is 3 hours. During the heating process, the micro electromagnetic vibrator is intermittently started to intermittently vibrate the cable being heated.

[0040] f: After the heating time is over, the heating is stopped and the cable enters the straightening cooling time. The straightening cooling time of the cable is 8 hours. At the same time, the control system starts the card tip to penetrate the cable surface. At the same time, the penetration depth displacement sensor measures the depth of the card tip penetrating the cable surface. The control system releases the restriction and fixation of the detection slider relative to the detection slide rail. As the straightening cooling progresses, the card tip begins to move along the detection slide rail as the cable surface retracts;

[0041] g: When the cooling time is over, the clamp tip is retracted relative to the clamp block, and the detection slide returns to the initial position relative to the detection slide rail. The cable retraction degree is calculated based on the displacement sensor's movement distance data in the detection slide rail and the compensation algorithm module. At this time, the heating blanket reduces the extrusion of the cable surface, and the straightness of the cable is detected with the help of the straightness detection component.

[0042] h: Start the laser distance meter to measure the distance between the cable surface and the block. Based on the collected spacing data, use the straightness calculation algorithm to obtain the straightness of the cable after heating and straightening, and compare the straightness calculated by the detection with the straightness eccentricity threshold;

[0043] h1: When the detected straightness is within the straightness eccentricity threshold, the reminder module is triggered to remind the technician;

[0044] h2: The detection straightness exceeds the straightness eccentricity threshold interval, triggering the control system to repeat step d and subsequent operations;

[0045] i: Following h1, turn off the control system, disassemble the device, remove the sealing strips wrapped around both ends of the fixing device, turn the rotating self-locking switch on the main self-locking plate, pull the pull head along the direction from the limit block to the pin, press the control button to unlock the pin in the slot, pull the pin out relative to the slot, and separate the fixing device as a whole from the cable.

[0046] The beneficial effects of adopting the above technical solution are:

[0047] 1. The cable surface is wrapped with an expandable or closable hinged fixture to avoid the cumbersome operation steps caused by manual winding in traditional technical solutions and the phenomenon of uneven heating of the cable and insufficient subsequent retraction. The fixture is wrapped and connected with an open-tail buckle device, which makes the overall wrapping operation simpler and completely wraps the surface of the cable to be heated. The equipment is more flexible and the overall neatness and beauty are higher, which simplifies the winding and wrapping operation on the cable surface and makes the overall disassembly and assembly more convenient.

[0048] 2. Abandon the traditional technical solution of using analysis and calculation, detect the cable shrinkage inside the fixture, detect and judge the thermal shrinkage properties of the cable insulation, and optimize the heating and straightening process. When it is detected that the cable straightness does not meet the standard, the cable is heated and straightened again to avoid secondary damage to the cable caused by repeated loading and unloading.

[0049] 3. The flexible fixing device makes the whole device suitable for cables of various radii, reducing the limitation of use. At the same time, the micro electromagnetic vibrator in the heating blanket can help the cable surface to heat evenly during heating, increase the cable's tolerance and reduce stress concentration.

[0082] When the rotation self-locking switch 665 on the main self-locking plate 61 is turned, the pull head 56 can be pulled along the main self-locking plate 61 from the limit block 57 to the latch 54, and cannot be pulled in the opposite direction; when the rotation self-locking switch 665 on the secondary self-locking plate 62 is turned, the pull head 56 can be pulled along the secondary self-locking plate 62 from the slot 55 to the limit block 57, and cannot be pulled in the opposite direction. The self-locking device 6 enhances the safety and durability of the open-end buckling device 5, and plays a double protection role for the cable surface wrapping.

[0083] Furthermore, the retraction detection device 4 is only arranged at one end of the fixing device 1 and has no installation direction restriction (see FIG. Figure 3The retraction detection device 4 is located at the end of the fixing device close to the latch 54), and the spacing between the end is about 5-8 cm. The retraction detection device 4 includes a detection rail 41, a detection slider 42 slidably installed in the detection rail 41 and connected to the control system, a clamping tip 43 installed on the detection slider 42 and capable of reciprocating relative to the detection slider 42, a displacement sensor fixed on the detection rail 41 for measuring the movement of the detection slider 42 in the detection rail 41, and a penetration depth displacement sensor fixed on the detection slider 42 for detecting the side penetration depth of the clamping tip 43 into the cable surface. The friction coefficient of the detection slider 42 in the detection rail 41 is 0.05-0.15;

[0084] The control system can release and start the fixation and movement of the detection slider 42 relative to the detection rail 41. The retraction detection device 4 includes a compensation algorithm module connected to the control system data. The compensation algorithm module includes a friction influence algorithm and a thermal expansion influence algorithm.

[0085] The working principle of the retraction detection device 4 is as follows: by detecting the movement of the slider 42 in the detection rail 41, the retraction of the cable surface after the clamping tip 43 penetrates the cable surface is measured. This method can realize real-time monitoring, and the principle is relatively simple. However, the friction of the slider 42 in the detection rail 41, the penetration depth of the clamping tip 43 and the cable material characteristics will affect the measurement result.

[0086] The impact of slider movement on detection accuracy includes friction: if the friction coefficient between the slider and the slide rail is too high, the slider will not accurately reflect the actual retraction of the cable; dynamic response: whether the response speed of the slider is fast enough also affects the accuracy within the measurement time; needle tip penetration depth: the consistency of the penetration depth is directly related to the measurement accuracy of the retraction degree. If the needle tip penetration depth is uneven, it may cause errors.

[0087] Therefore, the compensation algorithm module involves the friction effect algorithm and the thermal expansion effect algorithm as well as the relevant parameters involved in these two algorithms:

[0088] Slider displacement (D_s): displacement of the detection slider 42 in the detection rail 41,

[0089] Cable retraction (D_r): Cable retraction due to heating.

[0090] The penetration depth of the tip 43 (D_p): the depth of the tip 43 penetrating into the cable surface,

[0091] Friction coefficient (μ): the friction coefficient between the detection slider 42 and the detection rail 41,

[0092] Thermal expansion coefficient of cable material (α): affects the changes of the cable during heating.

[0093] Ambient temperature change (ΔT): affects the physical properties of the cable,

[0094] Initial length (L_0): The original length of the cable.

[0095] Friction affects the algorithm formula to estimate the actual retraction of the cable:

[0096] [D_r=D_s-(D_p\cdot\mμ)]

[0097] D_r: Actual cable retraction.

[0098] D_s: Slider displacement (i.e. measured displacement).

[0099] D_p: needle tip penetration depth.

[0100] μ: Influence of friction coefficient.

[0101] The above formula is a derivation based on mechanics and friction models. When the slider moves in the slide rail and is affected by friction, the movement of the slider is not completely equivalent to the retraction of the cable. When the tip 43 pierces the cable, part of the displacement (i.e. (D_p)) will not be effectively transmitted to the slider due to friction. Therefore, this part needs to be deducted to obtain the actual retraction amount. This compensation takes into account the displacement loss caused by friction, making the final calculation closer to the actual state of the cable.

[0102] Calculation example:

[0103] Assume that the measured slider displacement (D_s=10,mm)

[0104] Needle tip penetration depth (D_p=1,mm)

[0105] Friction coefficient (μ=0.1)

[0106] Then: [D_r=10,mm-(1,mm\cdot 0.1)=10,mm-0.1,mm=9.9,mm]

[0107] Compensation taking into account cable properties

[0108] Thermal expansion effect algorithm: needs to be adjusted according to the thermal expansion coefficient of the cable material. When the temperature changes (ΔT), the change in cable length can be calculated:

[0109] [\Delta L=L_0\cdot\alpha\cdot\Delta T]

[0110] Incorporate this length change into the calculation of the retraction amount and, if the cable shortening is due to heating, further corrections can be made using the above formula.

[0111] The calculation formula of the thermal expansion effect algorithm provides the theoretical length change of the cable due to temperature change, which provides a basis for the design and safety of the cable; the calculation formula of the friction effect algorithm supplements the error correction caused by factors such as friction in actual applications, making the final retraction measurement more accurate. The compensation algorithm module can effectively improve the accuracy of cable retraction measurement.

[0112] At the same time, the friction coefficient of the detection slider 42 in the detection rail 41 is 0.05-0.15. This range can ensure that the slider encounters less resistance when moving on the rail, so as to accurately reflect the retraction of the cable. Resistance control: This friction coefficient range can ensure that the slider encounters less resistance when moving on the rail, so as to avoid affecting the retraction of the cable. Accurate measurement: The appropriate friction coefficient helps to improve the accurate response of the sensor or measuring equipment to the retraction state of the cable and ensure the reliability of the data. Smoothness and stability: A friction coefficient that is too high may cause the slider to get stuck, while a friction coefficient that is too low may cause the slider to lose control. Selecting this range helps maintain the stability of the detection slider 42 in the detection rail 41. It is to ensure the smoothness and stability of the slider when moving on the rail to ensure accurate reflection of the cable retraction.

[0113] Example 3

[0114] A further technical solution based on Example 2: Fig. 9 As shown, the retraction detection device 4 includes a straightness detection component, which includes a laser rangefinder fixed on the detection slider 42 to detect the depth of the clamp tip 43 penetrating the cable surface, a straightness detection module connected to the laser rangefinder data, and a reminder module fixed on the support plate 14. The straightness detection module is provided with a straightness eccentricity threshold and a straightness calculation algorithm. The straightness detection component performs the following steps for detecting the straightness of the cable:

[0115] S1: reducing the pressure of the heating blanket 13 on the cable surface;

[0116] S2: Start the laser distance meter to measure the distance between the cable surface and the card block;

[0117] S3: Based on the collected spacing data, the straightness of the cable after heating and straightening is obtained by using a straightness calculation algorithm, and the straightness obtained by the detection calculation is compared with the straightness eccentricity threshold;

[0118] S4.1: When the detected straightness is within the straightness eccentricity threshold, the reminder module is triggered;

[0119] S4.2: Detecting that the straightness exceeds the straightness eccentricity threshold interval triggers the control system to cyclically heat the heating blanket 13 repeatedly.

[0120] When it is detected that the straightness of the cable after straightening and cooling does not meet the standard, the cable is heated and straightened again to optimize the heating and straightening process and avoid secondary damage to the cable caused by repeated loading and unloading.

[0121] Example 4

[0122] This embodiment requests to disclose a method for using an intelligent device for heating and straightening cables, based on the technical solutions of embodiments 1-3: Fig. 9 As shown, the specific steps are as follows:

[0123] a: Clean the surface of the cable end to be heated;

[0124] b: The head end movable plate 16 and the end movable plate 17 are rotated relative to the mutually hinged support plate 14 to open the fixing device 1, and the cable to be heated is placed on the heating blanket 13 in the fixing device 1;

[0125] c: Insert the latch 54 at the end of the main buckling chain 51 into the slot 55 at the end of the secondary buckling chain 52. As the latch 54 goes deeper into the slot 55, the locking plate 63 pops into the plate groove 64 to fix the latch 54 relative to the slot 55. Turn the rotating self-locking switch 665 on the secondary self-locking plate 62, and pull the pull head 56 along the secondary self-locking plate 62 from the slot 55 to the limit block 57. Wrap the part to be heated in the heating blanket 13, wrap the sealing strips 12 at both ends, and perform heat preservation and sealing on both ends of the heating cable.

[0126] d: Start the control device, the pressure sensor on the surface of the heating blanket 13 starts to record the pressure data on the surface, and compares the collected pressure data with the calculated pressure data. The control system controls the winding wheel 1010 to tighten and roll the pull rope 19 and the heating blanket 13 to adjust the heating blanket 13 and the fixing device 1 to evenly hold the cable surface;

[0127] e: After adjusting the heating blanket 13 to hold the cable surface evenly, the control system controls the heating blanket 13 to heat the cable surface at a temperature of 75°C-80°C for 3 hours. During the heating process, the micro-electromagnetic vibrator is intermittently started to vibrate the cable being heated;

[0128] f: After the heating time is over, the heating is stopped and the cable enters the straightening cooling time. The straightening cooling time of the cable is 8 hours. At the same time, the control system starts the clamp tip 43 to penetrate the cable surface. At the same time, the penetration depth displacement sensor measures the penetration depth of the clamp tip 43 into the cable surface. The control system releases the restriction and fixation of the detection slider 42 relative to the detection slide rail 41. As the straightening cooling proceeds, the clamp tip 43 begins to move along the detection slide rail 41 as the cable surface retracts;

[0129] g: When the cooling time is over, the clamping tip 43 is retracted relative to the clamping block, and the detection slide 42 returns to the initial position relative to the detection slide rail 41. The cable retraction degree is calculated according to the moving distance data of the clamping tip 43 in the detection slide rail 41 detected by the displacement sensor and the compensation algorithm module. At this time, the extrusion of the heating blanket 13 on the cable surface is reduced, and the straightness of the cable is detected with the help of the straightness detection component;

[0130] h: Start the laser distance meter to measure the distance between the cable surface and the block. Based on the collected spacing data, use the straightness calculation algorithm to obtain the straightness of the cable after heating and straightening, and compare the straightness calculated by the detection with the straightness eccentricity threshold;

[0131] h1: When the detected straightness is within the straightness eccentricity threshold, the reminder module is triggered to remind the technician;

[0132] h2: The detection straightness exceeds the straightness eccentricity threshold interval, triggering the control system to repeat step d and subsequent operations;

[0133] i: Following h1, turn off the control system, disassemble the device, remove the sealing strips 12 wrapped around both ends of the fixing device 1, turn the rotating self-locking switch 665 on the main self-locking plate 61, pull the pull head 56 along the direction of the limit block 57 to the pin 54, press the control button 65, unlock the fixation of the pin 54 in the slot 55, pull the pin 54 out relative to the slot 55, and separate the fixing device 1 as a whole from the cable.

Although the present application has been disclosed as a preferred embodiment as above, it is not intended to limit the present application. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present application. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
