[0002] The 10kV cable is an important part of the urban power distribution system. During the installation, maintenance and laying process of the cable, the demand for cable joints is huge, and the processing of cable joints involves the process of stripping the insulating layer and semi-conductive layer of the cable joints.

[0042] In the embodiments of the present invention, reference is made to Figure 1As shown in the figure, the cable stripping device may include a support mechanism, a feeding mechanism, a cutting mechanism, a temperature adjusting mechanism, and a depth adjusting mechanism; a stripping through hole 201 is provided on the support mechanism for the cable 100 to be stripped to pass through; the feeding mechanism is arranged on the support mechanism, and the working end of the feeding mechanism is located in the stripping through hole 201 for driving the cable 100 to be stripped to move along the axial direction of the stripping through hole 201; the cutting mechanism includes a rotating tool holder 410 and a tool body 420, the rotating tool holder 410 is movably arranged on the support mechanism along the circumferential direction of the stripping through hole 201, the tool body 420 is adjustably arranged on the rotating tool holder 410 along the radial direction of the stripping through hole 201, and the tool body 420 faces the stripping through hole 201 for stripping the cable 100 to be stripped; the temperature adjusting mechanism is arranged on the tool body 420 for adjusting the temperature of the tool body 420; the depth adjusting mechanism includes a current detection component and a first controller, the current detection component is used for monitoring the change of the current signal of the tool body 420, and the first controller is used for adjusting the stripping depth of the tool body 420 according to the change of the current signal of the tool body 420.

[0043] In an embodiment of the present disclosure, on the one hand, the feeding mechanism arranged on the support mechanism drives the cable 100 to be stripped to move along the axial direction of the stripping through hole 201, and the rotating tool holder 410 drives the tool body 420 to rotate around the cable 100 to be stripped, so that while the cable 100 to be stripped moves along the axial direction of the stripping through hole 201, the tool body 420 is used to perform circumferential stripping on the cable 100 to be stripped to ensure that the cable 100 to be stripped is stripped clean; on the other hand, the stripping depth of the tool body 420 cutting into the cable 100 to be stripped is also regulated in cooperation with the depth adjusting mechanism to ensure accurate stripping depth, and the temperature of the tool body 420 is adjusted in cooperation with the temperature adjusting mechanism to more efficiently strip cable material layers of different hardnesses.

[0044] Next, reference will be made to Figures 1 to 3 to describe the above device in the present exemplary embodiment in more detail.

[0045] In one embodiment, the cable stripping device further includes a housing 500, the housing 500 has a receiving cavity 501, the support mechanism, the feeding mechanism, and the cutting mechanism are located in the receiving cavity 501, and by arranging the support mechanism, the feeding mechanism, and the cutting mechanism in the receiving cavity 501 of the housing 500, the housing 500 provides a protective effect for the operator.

[0046] Furthermore, an observation window 520 is provided on the housing 500, and the observation window 520 can be a plastic shell made of a transparent material, so that while the operator can observe the operation situation inside the housing 500, it can also play a protective role.

[0047] Optionally, a handle 510 is provided on the outer wall of the housing 500. By providing the handle 510, it is convenient for the operator to carry the cable stripping device.

[0048] Exemplarily, the support mechanism includes a first support ring seat 210, a second support ring seat 220, and a third support ring seat 230 that are coaxially arranged. The inner cavities of the first support ring seat 210, the second support ring seat 220, and the third support ring seat 230 form the above-mentioned stripping through-hole 201. Among them, the first support ring seat 210 is connected to the inner wall of the housing 500 through a support arm 240, and the second support ring seat 220 and the third support ring seat 230 are arranged at both ends of the first support ring seat 210 along its axial direction.

[0049] In one embodiment, the feeding mechanism includes a first driving gear 310, a rotating shaft body 320, and a feeding wheel 330. The first driving gear 310 and the rotating shaft body 320 are installed on the support mechanism. The axial direction of the first driving gear 310 is arranged parallel to the axial direction of the stripping through-hole 201, and the axial direction of the rotating shaft body 320 is arranged along the radial direction of the stripping through-hole 201. One end of the rotating shaft body 320 is engaged with the first driving gear 310, and the other end is provided with a feeding wheel 330. The feeding wheel 330 serves as the working end and is used to drive the cable 100 to be stripped to move.

[0050] With the above structural arrangement of the feeding mechanism, during operation, the rotating shaft body 320 can be driven to rotate by rotating the first driving gear 310 to adjust the direction of the feeding wheel 330 on the rotating shaft body 320. When it is necessary to use the feeding wheel 330 to drive the cable 100 to be stripped to move, the axial direction of the feeding wheel 330 can be adjusted to be perpendicular to the direction of the cable 100 to be stripped. In this way, the rotation of the feeding wheel 330 can be used to drive the cable 100 to be stripped to move along the axial direction of the stripping through-hole 201. It should be noted that the feeding wheel 330 can also be used as a clamping member to clamp the cable 100 to be stripped when the cable 100 to be stripped only needs to be fixedly clamped, that is, even when the feeding wheel 330 remains stationary, a clamping effect can be provided on the cable 100 to be stripped.

[0051] Optionally, a driven gear 340 is fixedly provided at one end of the rotating shaft body 320, and the driven gear 340 is engaged with the first driving gear 310. By providing the driven gear 340 at one end of the rotating shaft body 320, the engagement between one end of the rotating shaft body 320 and the first driving gear 310 is realized.

[0052] Specifically, on the support mechanism, multiple groups of feeding mechanisms are arranged, and each group of feeding mechanisms includes three feeding mechanisms. For example, two groups of feeding mechanisms are arranged, and each group of feeding mechanisms includes three feeding mechanisms; among them, the first driving gears 310 of the two groups of feeding mechanisms are both arranged on the first support ring seat 210, and the multiple first driving gears 310 of each group of feeding mechanisms are arranged at intervals along the circumferential direction of the first support ring seat 210; the rotating shaft body 320 of one group of feeding mechanisms is arranged on the second support ring seat 220, and the rotating shaft body 320 of the other group of feeding mechanisms is arranged on the third support ring seat 230. By arranging multiple groups of feeding mechanisms, it can ensure that the feeding speed of the cable 100 to be stripped is evenly controllable and improve the stripping stability.

[0053] In one embodiment, the cutting mechanism further includes a second driving gear 430 installed on the support mechanism. The axial direction of the second driving gear 430 is parallel to the axial direction of the stripping through hole 201. The rotating tool holder 410 is connected to the output end of the second driving gear 430 to move along the circumferential direction of the stripping through hole 201.

[0054] With the above structural arrangement of the cutting mechanism, by rotating the second driving gear 430 to drive the rotating tool holder 410 to move along the circumferential direction of the stripping through hole 201, the tool body 420 can rotate around the cable 100 to be stripped, so that while the cable 100 to be stripped moves axially along the stripping through hole 201, the tool body 420 is used to perform circumferential stripping on the cable 100 to be stripped.

[0055] Optionally, a connecting seat 440 is provided on the end face of the second driving gear 430 along its axial direction, and the rotating tool holder 410 is installed on the connecting seat 440. That is, the connecting seat 440 can be used as the output end of the second driving gear 430. When the second driving gear 430 rotates, it drives the rotating tool holder 410 to move along the circumferential direction of the stripping through hole 201.

[0056] In one embodiment, the temperature regulating mechanism includes a temperature sensor, a heating element and a second controller. The temperature sensor and the heating element are respectively connected to the second controller. The temperature sensor is used to monitor the real-time temperature of the tool body 420, and the heating element is used to heat the tool body 420 under the control of the second controller.

[0057] With the above setting of the temperature regulating mechanism, during operation, the real-time temperature of the tool body 420 is collected by the temperature sensor and transmitted to the second controller. The first controller can compare the collected real-time temperature with the corresponding preset temperature. Thus, when the temperature of the tool body 420 needs to be increased, the heating element is controlled by the second controller to heat the tool body 420.

[0058] It should be noted that since the cable 100 to be stripped includes multiple material layers, such as an outer skin layer, a semiconductor layer, and a conductor layer, and the hardness of these different material layers is different, the resistance encountered by the tool body 420 when stripping different material layers is different. In order to strip the cable better and more efficiently, corresponding preset temperatures are set for stripping different material layers in this embodiment. For example, for a material layer with a relatively high hardness, a relatively high preset temperature is set, so that the material layer with a relatively high hardness can be softened during stripping, thereby reducing the cutting resistance to a certain extent and facilitating the tool body 420 to strip the cable.

[0059] In one embodiment, the current detection assembly includes a current sensor and a power supply module. The current sensor is disposed on the tool body 420 and electrically connected to the first controller. The power supply module is disposed on the support mechanism and electrically connected to the tool body 420 and the feed wheel 330.

[0060] Wherein, the tool body 420 generates a current under the action of the power supply module, and the current sensor is used to collect the real-time current signal of the tool body 420.

[0061] It should be noted that the first support ring seat 210, the second support ring seat 220, and the third support ring seat 230 of the support mechanism in this embodiment are made of metal. When the power supply module works, a current loop can be formed among the support mechanism, the tool body 420, the cable 100 to be stripped, and the feed wheel 330. Furthermore, the real-time current signal of the tool body 420 can be collected through the current sensor, so as to obtain the change of the current signal of the tool body 420.

[0062] It should be noted that the cable 100 to be stripped includes multiple material layers, such as an outer skin layer, a semiconductor layer, and a conductor layer. Based on the different conductivities of the outer skin layer, the semiconductor layer, and the conductor layer, when the tool body 420 cuts different cable material layers, the resistance in the above current loop will be different. Therefore, the real-time current signal of the tool body 420 collected by the current sensor will change. By obtaining this change in the current signal, it can be determined whether the tool body 420 is always in the cable material layer that needs to be cut during the stripping process, so that the stripping accuracy can be further adjusted. The device provided in this embodiment, especially for cables with non-standard internal specifications, has the problem that the set initial target stripping depth cannot meet the stripping accuracy of the entire cable, and the stripping depth needs to be appropriately adjusted.

[0063] Exemplarily, a driving motor electrically connected to the first controller is provided on the rotating tool holder 410, and the tool body 420 is connected to the output end of the driving motor. When the first controller adjusts the stripping depth of the tool body 420 according to the change of the current signal of the tool body 420, the first controller can control the driving motor to adjust the position of the tool body 420, so as to realize adjusting the stripping depth of the tool body 420 cutting into the cable 100 to be stripped.

[0064] In this exemplary embodiment, a cable stripping method is first provided. Referring to Figure 4 as shown, the cable stripping method may include the following steps:

[0065] Step S101: Place the cable to be stripped at the stripping through hole, and drive the cable to be stripped to move through the feeding mechanism;

[0066] Step S102: Rotate the tool holder to drive the tool body to rotate around the cable to be stripped, and use the tool body to strip the cable to be stripped;

[0067] Step S103: Monitor the change of the current signal of the tool body, and adjust the stripping depth of the tool body cutting into the cable to be stripped or the feeding speed of the feeding mechanism according to the change of the current signal;

[0068] Step S104: Monitor the real-time temperature of the tool body, and control the temperature of the tool body according to the preset temperature, stripping depth and real-time temperature;

[0069] Step S105: When the cable to be stripped is stripped in place, the feeding mechanism stops working, and the rotating tool holder continues to drive the tool body to rotate around the cable to be stripped to cut off the cable to be stripped;

[0070] Step S106: The rotating tool holder and the tool body stop working.

[0071] Next, in combination with Figures 1 to 3 the above method in this exemplary embodiment will be described.

[0072] In an embodiment of the present disclosure, on the one hand, the feeding mechanism drives the cable 100 to be stripped to move axially along the stripping through-hole 201, and the rotating tool holder 410 drives the tool body 420 to rotate around the cable 100 to be stripped, so that while the cable 100 to be stripped moves axially along the stripping through-hole 201, the tool body 420 is used to perform circumferential stripping on the cable 100 to be stripped, ensuring that the cable 100 to be stripped is stripped cleanly; on the other hand, by monitoring the change of the current signal of the tool body 420 and adjusting the stripping depth of the tool body 420 cutting into the cable 100 to be stripped or the feeding speed of the feeding mechanism according to the change of the current signal, to ensure accurate stripping, and also by monitoring the real-time temperature of the tool body 420 and controlling the temperature of the tool body 420 according to the preset temperature, stripping depth and real-time temperature, so as to strip the cable material layers of different hardness more efficiently.

[0073] Next, each step of the above method in this exemplary embodiment will be described in more detail.

[0074] Exemplarily, in step S101, the cable 100 to be stripped is placed at the stripping through-hole 201, and the feeding mechanism drives the cable 100 to be stripped to move axially along the stripping through-hole 201, so that when subsequent stripping operations are performed, while the cable 100 to be stripped moves axially along the stripping through-hole 201, the tool body 420 is used to perform circumferential stripping on the cable 100 to be stripped.

[0075] In one embodiment, before using the tool body 420 to strip the cable 100 to be stripped in step S102, the following steps are further included:

[0076] Set the cutting path and the initial target stripping depth according to the specification of the cable 100 to be stripped, and adjust the initial stripping position of the tool body 420 according to the initial target stripping depth;

[0077] Obtain the position of the cable material layer where the tool body 420 is located according to the current signal of the tool body 420;

[0078] Adjust the current temperature of the tool body 420 according to the position of the cable material layer where the tool body 420 is located and the preset temperature corresponding to the cable material layer.

[0079] It should be noted that, based on the different specifications of the cable 100 to be stripped, corresponding initial target stripping depths need to be set for different specifications of the cable 100 to be stripped, so as to ensure that in the initial state, the tool body 420 can cut into the cable 100 to be stripped from the outer surface of the cable 100 to the initial target stripping depth. In addition, since the cable 100 to be stripped includes multiple cable material layers, and the material hardness and cutting characteristics of the multiple cable material layers vary greatly, corresponding cutting paths need to be preset for different cables 100 to be stripped. The cutting characteristics are, for example, the temperature during cutting, etc.

[0080] In addition, the cable 100 to be stripped includes multiple material layers, such as an outer skin layer, a semiconductor layer, and a conductor layer. The hardness of these different material layers is different, so the resistance encountered by the tool body 420 when stripping different hardness material layers is different. In order to strip the cable better and more efficiently, corresponding preset temperatures are set for stripping different cable material layers in this embodiment. For example, for a cable material layer with a relatively large hardness, a relatively high preset temperature is set, so that the cable material layer with a relatively large hardness can be softened during stripping, thereby reducing the cutting resistance to a certain extent and facilitating the tool body 420 to strip the cable.

[0081] By adjusting the current temperature of the tool body 420 according to the position of the cable material layer where the tool body 420 is located and the preset temperature corresponding to the cable material layer, different degrees of softening can be achieved for cable material layers with different hardnesses during stripping, thereby controlling the cutting resistance and facilitating the tool body 420 to strip the cable.

[0082] In one embodiment, to monitor the change in the current signal of the tool body 420 in step S103, a current sensor provided on the tool body 420 can be used to monitor the current signal of the tool body 420, so as to obtain the current change amount of the tool body 420. According to the obtained current change amount, the current difference value between the front and rear moments can be determined.

[0083] In one embodiment, according to the current change in step S103 to adjust the stripping depth of the tool body 420 cutting into the cable 100 to be stripped or the feeding speed of the feeding mechanism may further include the following steps:

[0084] When the change in the current signal is greater than the first set threshold, reduce the feeding speed of the feeding mechanism and control the stripping depth of the tool body 420 cutting into the cable 100 to be stripped to the preset maximum depth value;

[0085] When the change in the current signal is less than or equal to the first set threshold, reduce the feeding speed of the feeding mechanism and increase the stripping depth of the tool body 420 cutting into the cable 100 to be stripped.

[0086] By introducing the set threshold to judge the change of the current signal and regulating the feed speed of the feed mechanism and the stripping depth of the tool body 420 according to the judgment result, corresponding adjustment measures can be selected to ensure the accuracy of the entire stripping process. It should be noted that the above adjustment of the stripping depth of the tool body 420 cutting into the cable 100 to be stripped or the feed speed of the feed mechanism according to the current change is for the deep cutting condition. Taking the cable to be cut including the outer skin layer, the semiconductor layer and the conductor layer as an example, the deep cutting condition is: preset to cut to the contact part between the semiconductor layer and the conductor layer without damaging the conductor layer.

[0087] Furthermore, a second set threshold greater than the first set threshold can be further introduced to more optimally control the cutting accuracy of the above deep cutting condition;

[0088] Among them, when the change of the current signal is greater than the first set threshold and less than the second set threshold, it is necessary to significantly reduce the feed speed of the feed mechanism and control the stripping depth of the tool body 420 cutting into the cable 100 to be stripped to the preset maximum depth value;

[0089] When the change of the current signal is greater than the second set threshold, the feed speed is adjusted to be close to 0, and the stripping depth of the tool body 420 cutting into the cable 100 to be stripped is controlled to be the preset maximum depth value.

[0090] It should be noted that in the above deep cutting condition, by introducing the first set threshold and the second set threshold, the deep cutting is controlled.

[0091] To more clearly explain the adjustment effect of the set threshold on the stripping depth, the following further gives a comparison and explanation of the shallow cutting condition and the third set threshold. Among them, the third set threshold is less than the first set threshold, and the above shallow cutting condition is: preset to cut to the outer skin layer of the cable.

[0092] When the change of the current signal is less than the third set threshold, the feed mechanism can maintain a high feed speed and control the stripping depth of the tool body 420 cutting into the cable 100 to be stripped to the preset minimum depth value; this can ensure that the tool body 420 maintains a high rate of shallow cutting of the cable to be stripped. Among them, the preset minimum depth value can be set according to the thickness of the outer skin layer of different cables.

[0093] It should be noted that since the cable 100 to be stripped includes multiple material layers, such as an outer skin layer, a semiconductor layer, and a conductor layer, based on the different electrical conductivities of the outer skin layer, the semiconductor layer, and the conductor layer, when the tool body 420 cuts into different cable material layers, the real-time current signal of the tool body 420 collected by the current sensor will change. By obtaining such a change in the current signal, it can be determined whether the tool body 420 has been cutting into the cable material layer that needs to be cut during the stripping process, so that the stripping accuracy can be further regulated.

[0094] Therefore, in this embodiment, in combination with the limitation that the above third set threshold is less than the first set threshold, and the first set threshold is less than the second set threshold, by comparing the change in the current signal with the first set threshold, the second set threshold, and the third set threshold, the cable material layer where the tool body 420 is located can be obtained, and then the regulation that affects the stripping depth of the tool body and the feeding speed of the feeding mechanism can be performed.

[0095] Among them, when the change in the current signal is less than the third set threshold, it indicates that the tool body 420 is in the outer skin layer of the cable. At this time, the shallow cutting condition can be maintained, and the cable can be shallowly cut at a relatively high feeding speed and the preset minimum depth value D min for shallow cutting of the cable;

[0096] The feeding speed of the feeding mechanism can be specifically regulated according to the following rules:

[0097] The smaller the change value of the current signal, the higher the feeding speed of the feeding mechanism.

[0098] When the change in the current signal is greater than the third set threshold and less than the first set threshold, it indicates that the tool body 420 has cut from the outer skin layer of the cable into the harder semiconductor layer. At this time, in order to avoid uneven cutting and overloading of the tool body 420, it is necessary to appropriately reduce the feeding speed of the feeding mechanism and gradually increase the stripping depth of the tool body 420 cutting into the cable 100 to be stripped. The stripping depth of the tool body 420 can be controlled by the formula (1):

[0099] D = D min + k1·(ΔI - ΔI low )(1)

[0100] Among them, D represents the stripping depth, D min represents the preset minimum depth value, k1 represents the first adjustment coefficient, ΔI represents the change value of the current signal, and ΔI low represents the third set threshold;

[0101] The feeding speed of the feeding mechanism can be specifically regulated according to the following formula (2):

[0102]

[0103] Among them, V feed represents the feed speed, V max represents the preset maximum feed speed, k2 represents the second adjustment coefficient, and ΔI medium represents the first set threshold value.

[0104] When the change in the current signal is greater than the first set threshold value and less than the second set threshold value, it indicates that the tool body 420 has cut into the hard conductor layer from the semiconductor layer of the cable. At this time, in order to avoid overcutting of the tool body 420 and overload damage of the tool body 420, it is necessary to significantly reduce the feed speed of the feed mechanism and control the stripping depth of the tool body 420 cut into the cable 100 to be stripped;

[0105] The stripping depth of the tool body 420 can be controlled by formula (3):

[0106] D = D max - k3·(ΔI - ΔI medium )(3)

[0107] Among them, D represents the stripping depth, D max represents the preset maximum depth value, D max > D min , k3 represents the third adjustment coefficient, ΔI represents the change value of the current signal, and ΔI medium represents the first set threshold value;

[0108] The feed speed of the feed mechanism can be specifically adjusted according to the following formula (4):

[0109] V feed = V min + k4·(ΔI - ΔI medium )(4)

[0110] Among them, V feed represents the feed speed, V min represents the preset minimum feed speed, V min < V max , k4 represents the fourth adjustment coefficient, and ΔI medium represents the first set threshold value.

[0111] When the change in the current signal is greater than the second set threshold value, it indicates that the tool body 420 has cut into the hard conductor layer. At this time, the increase in the stripping depth should be restricted and the feed speed should be slowed down. To avoid overcutting and damage of the tool body 420, the feed speed can be adjusted to be close to 0 or adjusted to the preset minimum feed speed V min , and the stripping depth of the tool body 420 cut into the cable 100 to be stripped is controlled to be the preset maximum depth value D max .

[0112] It should be noted that the first adjustment coefficient, the second adjustment coefficient, the third adjustment coefficient, and the fourth adjustment coefficient need to be optimized through actual test data. Since the cutting characteristics of each cable are different, these adjustment coefficients should be adjustable according to the current response and cutting performance of different cables.

[0113] Optionally, for the cable 100 to be stripped with an outer sheath, a semiconductor layer, and a conductor layer, the cutting path can be set as follows: starting from the outer sheath, gradually penetrate into the semiconductor layer until the critical position where the semiconductor layer contacts the conductor layer is cut. When cutting layer by layer, when cutting different cable material layers, the cutting can be performed according to step S103; at the same time, during the process of adjusting the stripping depth in real time according to step S103, the cutting path can be updated according to the real-time changing stripping depth.

[0114] Optionally, the cutting path should follow hierarchical segmentation and adjust the path for different cable material layers. For example, when peeling the outer sheath, the cutting path of the outer sheath needs to ensure that the rotation speed of the tool body 420 is uniform, and the feeding mechanism maintains a uniform feeding speed. When cutting to the conductor layer, the stripping depth can be adjusted in real time according to step S103, and the cutting path can be updated in a timely manner to avoid the tool body 420 accidentally cutting into the conductor layer and ensure that the conductor layer is as intact as possible.

[0115] Optionally, the cutting path can be generated by using the spline interpolation algorithm, generating a smooth curve based on multiple data points and ensuring that the tangent of the curve at the data points is continuous. This smooth curve is the cutting path and can be expressed by the following formula:

[0116] f(x) = a n x 3 + b n x 2 + c n x + d n (5)

[0117] where f(x) represents the cutting path, a n represents the coefficient of the polynomial, b n represents the coefficient of the polynomial, c n represents the coefficient of the polynomial, d n represents the coefficient of the polynomial, x represents the variable to be interpolated, and n represents the segmentation number, used to distinguish polynomials in different intervals.

[0118] The above spline interpolation algorithm can generate a cubic polynomial function near each data point to ensure the smoothness of the generated cutting path. The cutting path generated by the spline interpolation algorithm can ensure that the movement of the tool body 420 remains continuous and stable, avoiding mechanical vibrations or damages caused by too sharp a cutting path.

[0119] It should be noted that the multiple data points used for generating the cutting path include the stripping start position data, the stripping end position data, the stripping depth data, the turning position data, the cutting angle data, etc. Through the spline interpolation algorithm, a smooth and continuous cutting path can be generated based on the above-mentioned various data points, ensuring that the tool body 420 moves precisely along a predetermined trajectory during the stripping process. It should also be noted that these data points can be obtained through sensors or other monitoring devices, which is more conducive to fitting a cutting path that conforms to the actual cutting situation. Of course, the cutting path can also be adjusted based on these real-time obtained data points. Of course, in other embodiments, especially in the case of complex geometric shapes or high-precision control requirements, these data points can also be determined in advance through 3D modeling and adjusted in real time during actual cutting.

[0120] It should be explained that the above-mentioned stripping start position data and stripping end position data can be understood as the coordinate positions where the tool body 420 starts and ends cutting, usually determined by preset cable cutting start points or cutting end points. The above-mentioned stripping depth data can be understood as the depth of stripping the cable surface layer, which can be measured by a sensor. The above-mentioned turning position data can be understood as: in the case where the cutting path has a turn or bend, the turning position needs to be determined through a path planning algorithm or an actual monitoring device. The above-mentioned cutting angle data can be understood as: usually based on the cable shape and the area to be stripped, the cutting angle can be determined through path interpolation or dynamic control.

[0121] It should also be noted that the steps for generating the above-mentioned cutting path may include: obtaining multiple data points; generating a preliminary cutting path using the spline interpolation algorithm based on the obtained data points; and dynamically adjusting the cutting path according to real-time feedback and the collected data points.

[0122] In step S104, the real-time temperature of the tool body 420 can be monitored through a temperature sensor, and the temperature of the tool body 420 can be regulated according to the corresponding preset temperature, the stripping depth of the tool body 420, and the real-time temperature. Among them, the stripping depth of the tool body 420 in step S104 can be determined by the stripping depth adjusted in real time according to the change of the current signal in step S102. In this way, the position of the cable material layer where the tool body 420 is located can be obtained, and then combined with the corresponding preset temperature and the monitored real-time temperature of the tool body 420 to regulate the temperature of the tool body 420 to ensure that the tool body 420 can be in a temperature range that is more conducive to stripping the cable.

[0123] Specifically, when it is necessary to increase the temperature of the tool body 420, the heating element can be used to heat the tool body 420, and the heating power of the heating element can be increased to quickly raise the temperature of the tool body 420; when it is necessary to lower the temperature of the tool body 420, the heating power of the heating element can be reduced or the heating element can be turned off.

[0124] In addition, it should be noted that the current signal change result of monitoring the tool body 420 in step S103 can also be directly used to regulate the temperature of the tool body 420 in step S104. For example, when the change in the current signal is greater than the set threshold, it indicates that the tool body 420 enters a cable material layer with a greater hardness. At this time, the corresponding preset temperature is relatively high. If the real-time temperature of the tool body 420 is relatively low, the heating power of the heating element can be increased to raise the temperature of the tool body 420, soften the cable material layer, and reduce the cutting resistance; when the change in the current signal is less than the set threshold, it indicates that the tool body 420 is close to the target stripping depth or the tool body 420 has been in the same cable material layer, and the heating power of the heating element can be appropriately reduced to avoid overheating of the tool body 420.

[0125] It should also be noted that a temperature threshold is set for the tool body 420 to avoid damage to the tool body 420 due to overheating.

[0126] For example, in step S105, along the length direction of the cable 100 to be stripped, when the cable 100 to be stripped is stripped in place, the feeding mechanism stops working, and the rotating tool holder 410 continues to drive the tool body 420 to rotate around the cable 100 to be stripped to cut off the cable 100 to be stripped.

[0127] For example, in step S106, after the cable 100 to be stripped is cut off, the rotating tool holder 410 and the tool body 420 stop working.

[0128] It should be noted that it can be confirmed that the cable 100 to be stripped is stripped in place through current monitoring and a contact depth sensor. Stripping in place includes: the cable material layer to be stripped has been peeled off from the cable or the stripping depth has been reached. Among them, the contact depth sensor usually relies on mechanical touch or contact to measure the position of the tool body 420. For example, the contact depth sensor can be a linear variable differential transformer. The linear variable differential transformer is installed near the tool body 420, and the position change of the tool body 420 is fed back by detecting the linear displacement of the tool body 420.

[0129] In one embodiment, before using the tool body 420 to strip the cable 100 to be stripped in step S102, the following steps are further included:

[0130] Start the tool wear monitoring module to monitor the wear of the tool body 420 during the cutting process using the tool wear monitoring module.

[0131] Specifically, the above-mentioned tool wear monitoring can be achieved by installing a vibration sensor on the tool body 420. During the cutting process, the vibration sensor is used to collect the vibration signal and cutting noise of the tool body 420 in real time. By analyzing and processing the collected vibration signal and cutting noise, if it is analyzed that the detected vibration signal and cutting noise are abnormal, it is determined that the tool body 420 is worn, the cutting speed of the tool body 420 is reduced, and a warning message is sent to the operator to indicate that the tool body 420 is worn and needs to be replaced or repaired.

[0132] In one embodiment, before using the tool body 420 to strip the cable 100 in step S102, the following steps are further included:

[0133] Start the tension monitoring module to adjust the feeding speed of the feeding mechanism during the cutting process using the tension monitoring module.

[0134] Specifically, the above-mentioned tension monitoring can be achieved by installing a tension sensor on the feeding wheel 330 of the feeding mechanism. The tension sensor is used to monitor the tension change of the cable 100 to be stripped in real time. If the monitored tension value exceeds the preset normal range, it is determined that the feeding of the cable 100 to be stripped is abnormal. The feeding abnormality includes situations such as cable position deviation or abnormal tension on the cable. At this time, the feeding speed needs to be adjusted or the cutting operation needs to be stopped.

[0135] Optionally, the update and adjustment of the cutting path are mainly based on the real-time monitored data and the preset adjustment rules. That is, by obtaining the real-time tool body position data, current signal change, tension change, and temperature data, the path deviation can be calculated based on the real-time tool body position data and the preset cutting path. The stripping depth adjustment information and feeding speed adjustment information can be obtained based on the current signal change and tension change. When the calculated path deviation exceeds the preset deviation range, it enters the path adjustment mode. Specifically, the spline interpolation algorithm and the real-time tool body position data can be used to generate a new stripping path, and the feeding speed and stripping depth can be dynamically adjusted in combination with the current signal change and tension change to ensure stable cutting.

[0136] It should be noted that before step S102, the above-mentioned various device parameters can be initialized to ensure the normal operation of each sensor and control device. Set the initial stripping parameters according to the specifications of the cable 100 to be stripped and the stripping task. For example, the preset temperature set for each cable material layer of the cable 100 to be stripped, the set threshold set for the current signal change, the initial target stripping depth, and the initial preset cutting path, etc.

[0137] By analyzing the data of each stripping operation, the relationship between current, temperature and stripping depth is evaluated, and aspects such as temperature control, stripping depth adjustment and cutting path during the stripping process are optimized to improve the stripping accuracy and efficiency.
