Description

Technical Field

[0001] This invention relates to the field of high-altitude cable operations, and more particularly to an automated stripping and connection device for overhead cables. Background Technology

[0002] As a core component of the power system, the reliability of overhead transmission lines directly affects the safety and stability of the entire power grid. Cable connection is an essential part of power grid construction, maintenance, and fault repair. Whether it is the erection of new lines, the extension of old lines, or the repair of locally damaged sections, precise stripping of cable ends is required. This involves removing a certain length of the outer insulation of the cable to expose the internal conductors for reliable crimping or bolting.

[0003] To address these issues, automated wire stripping devices have emerged. Existing automated wire stripping devices typically employ a modular design, integrating clamping, cutting, and stripping functions. However, these devices cannot adapt to varying cable diameters and insulation thicknesses, requiring a separate stripping device for each type of cable, resulting in low adaptability. Furthermore, existing technologies severely neglect the impact of surface contaminants on cables in high-altitude environments. Overhead cables, exposed to the elements for extended periods, accumulate dust, salt, metal debris, bird droppings, and other contaminants on their surfaces, forming a contamination layer of considerable thickness and hardness. During traditional stripping processes, these contaminants are dispersed by mechanical vibrations and operational disturbances, easily adhering to the newly exposed conductor surface. Existing devices lack effective contaminant treatment mechanisms, failing to guarantee the cleanliness of the connection surfaces. Contaminated contact surfaces lead to significantly increased contact resistance, causing localized overheating during long-term operation and posing a potential safety hazard to the power grid.

[0004] In conclusion, there is an urgent need to develop a new wire stripping device to solve the above problems. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides an automated stripping and connection device for overhead cables.

[0006] To achieve the above objectives, on one hand, the present invention provides an automated stripping and connection device for overhead cables, comprising a device body, the device body comprising: connecting shells located at both ends of the device body, a clamping device and a ring-cutting device sequentially arranged inside the connecting shells along the direction from one side of the connecting shell to the other side, a decontamination device, a wire cutting device, and a wire stripping device slidably connected between the two ring-cutting devices and the connecting shells; wherein, the decontamination device comprises a decontamination positioning mechanism and a decontamination cleaning mechanism, the decontamination positioning mechanism comprising a decontamination positioning motor, a decontamination lead screw disposed at the output end of the decontamination positioning motor, a decontamination slider threadedly engaged with the decontamination lead screw, and a first mounting box for the decontamination assembly fixedly connected to one end of the decontamination slider extending out of the connecting shell;

[0007] The cleaning mechanism includes: a mounting plate disposed in the first mounting box; a plurality of electromagnetic coils fixedly connected to the mounting plate; a plurality of permanent magnets surrounding the electromagnetic coils; two fixed connecting columns fixedly connected between the two mounting plates and offset from the center of the rotating plate by a certain distance; and two sliding connecting columns connected to the two fixed connecting columns on one side of the mounting plate offset from the center of the mounting plate by elastic telescopic members; wherein, a cleaning sheet is wrapped between the two fixed connecting columns and the two sliding connecting columns;

[0008] The decontamination positioning motor is used to drive the first mounting box to slide on the connecting shell for positioning. When the electromagnetic coil is energized, it generates a magnetic field that interacts with the permanent magnet to drive the mounting plate to rotate for cable surface decontamination treatment.

[0009] The clamping device is used to clamp the overhead cable. When the decontamination positioning motor drives the first mounting box to move closer to the cable, the decontamination plate surrounding the fixed connecting column and the sliding connecting column is pressed tightly against the cable. The sliding connecting column is compressed towards the fixed connecting column due to the obstruction of the cable, so that the decontamination plate is pressed tightly against the cable. When the electromagnetic coil is energized, the rotating disk drives the decontamination plate to rotate around the cable to achieve decontamination of the cable surface.

[0010] In a preferred embodiment of the present invention, the stain-removing sheet is a non-woven fabric with a brush attached to its outer surface.

[0011] In a preferred embodiment of the present invention, the clamping device includes a clamping drive motor, a clamping screw connected to the output shaft of the clamping drive motor, a clamping slider that cooperates with the clamping screw and is slidably connected in the connecting housing, and a V-shaped clamping block fixedly connected to the end of the clamping slider by a connecting rod; the clamping drive motor controls the two V-shaped clamping blocks to open and close synchronously through the cooperation of the clamping screw and the clamping slider, so as to realize the clamping and release of the cable.

[0012] In a preferred embodiment of the present invention, the inner side of the V-shaped clamping block is provided with anti-slip texture or flexible pad.

[0013] In a preferred embodiment of the present invention, the circumferential cutting device includes a depth control mechanism and a circumferential cutting mechanism; wherein, the depth control mechanism includes a depth control motor, an open gear disk meshing with the output end of the depth control motor, a plurality of blade limiting members disposed at one end of the open gear disk, and a pressure feedback unit mounted on the blade limiting members; a plurality of arc-shaped sliding rails are arranged circumferentially along the central axis of the open gear disk, and blade mounting rods are disposed at both ends passing through the arc-shaped sliding rails, one end of the blade mounting rod is slidably connected to the blade limiting member and is limited by the sliding of the blade limiting member, and one end of the blade limiting member is fixedly connected to a circumferential cutting blade; when the depth control motor drives the open gear disk to rotate, under the contact of the arc-shaped sliding rails and the blade limiting members, the blade mounting rod moves away from or closer to the central axis of the blade disk mounting plate, thereby controlling the cutting depth of the blade.

[0014] In a preferred embodiment of the present invention, the circumferential cutting mechanism includes a circumferential cutting drive disk rotatably connected to the connecting shell and having teeth on both its inner and outer ring surfaces; a circumferential cutting drive motor meshing with the outer gear surface of the circumferential cutting drive disk; and a planetary gear meshing around the inner gear surface of the circumferential cutting drive disk and the outer gear surface of the open gear disk. The depth control motor is fixedly connected to the circumferential cutting drive disk, and the blade limiting member is fixedly connected to the circumferential cutting drive disk. When the circumferential cutting drive motor is running, the circumferential cutting drive disk drives the planetary gear and the open gear disk to rotate as a whole, thereby achieving circumferential cutting of the cable insulation layer.

[0015] In a preferred embodiment of the present invention, the wire cutting device includes a wire cutting drive motor, a wire cutting screw disposed at the output end of the wire cutting drive motor, a wire cutting slider threadedly engaged with the wire cutting screw, and a wire cutting head fixedly connected to the wire cutting slider; the wire cutting drive motor drives the wire cutting head to move axially along the cable through the threaded wire cutting screw and the wire cutting slider, for longitudinal cutting between the annular cuts completed by the circumferential cutting device; wherein, the starting point of the wire cutting device coincides with the circumferential cutting position of the circumferential cutting device.

[0016] In a preferred embodiment of the present invention, the wire stripping device includes a wire stripping drive motor, a wire stripping screw disposed at the output end of the wire stripping drive motor, a wire stripping slider threadedly engaged with the wire stripping screw, and a V-shaped wire stripping plate fixedly connected to the wire stripping slider; the wire stripping drive motor drives the V-shaped wire stripping plate to move along the cable axial direction to strip the insulation segments that have been circumferentially cut and longitudinally cut from the cable conductor.

[0017] In a preferred embodiment of the present invention, an adjustment device is further provided on the side of the decontamination device on the connecting shell. The adjustment device includes: a second mounting box disposed on the side of the connecting shell away from the first mounting box; a first adjustment motor for driving the second mounting box away from or closer to the cable; and a second adjustment motor for adjusting the stripping device and the cutting device to move closer to or further away from the cable in the longitudinal direction to switch the working mode.

[0018] On the other hand, this application provides an automated stripping method for overhead cables, based on an automated stripping and connection device for overhead cables as described in any of the above claims, characterized by comprising the following steps:

[0019] S1. Move the device to the cable working position and drive the clamping device to firmly clamp the cable;

[0020] S2. Drive the cleaning device close to the cable, so that the cleaning pad adaptively covers and adheres tightly to the cable surface before rotating to clean.

[0021] S3. The ring cutting device is started, driving the ring cutting disc to rotate, and simultaneously controlling multiple ring cutting blades to feed radially in sync, cutting a ring-shaped cut of a predetermined depth in the cable insulation layer;

[0022] S4. By adjusting the device, the cutting device is brought closer to the cable, and the cutting device is driven to move along the cable axis to make longitudinal cuts between the two annular cuts.

[0023] S5. By adjusting the device, the stripping device replaces the cutting device and approaches the cable, driving the stripping device to slide along the cut insulation section and peel it off from the cable conductor.

[0024] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0025] (1) This device achieves stable and adaptive clamping of the cable by adopting a clamping device consisting of a clamping drive motor, a clamping screw, a clamping slider and a V-shaped clamping block. This design allows the two V-shaped clamping blocks to converge towards the center of the cable synchronously, ensuring a symmetrical distribution of clamping force, effectively preventing the cable from shifting or twisting during operation, and adapting to cables of different sizes. Compared with the prior art, the solution of this application not only improves the reliability of clamping, but also adapts to cables of different sizes.

[0026] (2) This device is designed with a decontamination device including a decontamination positioning mechanism and a decontamination cleaning mechanism. The decontamination positioning motor drives the decontamination cleaning mechanism to approach the cable, so that the decontamination sheet wrapped on the fixed connecting column and the sliding connecting column can adaptively cover the cable surface, so that the decontamination sheet can closely fit the curved surface of the cable with different diameters. Then, by energizing the electromagnetic coil on the outer ring surface of the mounting plate, it generates an interaction force with the peripheral permanent magnet, thereby realizing the rotation of the mounting plate, which in turn drives the decontamination sheet to perform circumferential cleaning motion. This design overcomes the defect of neglecting the treatment of contaminants on the cable surface in the existing technology, realizes the effective removal of contaminants such as dust, oxides, and salt crystals, avoids the impact of contaminants on the subsequent connection quality, and significantly improves the reliability and safety of cable connection.

[0027] (3) By setting up a depth control mechanism including a depth control motor, an open gear disk, an arc-shaped sliding rail, and a pressure feedback unit, the circumferential cutting depth is controlled. Compared with the open-loop control in the prior art, which is difficult to adapt to cable diameter fluctuations and material inhomogeneity, this device can ensure that the circumferential cutting blade cuts into the insulation layer with constant pressure, which not only ensures the consistency of the circumferential cut depth, but also avoids damage to the internal conductor of the cable, greatly improving the quality and stability of the wire stripping operation.

[0028] (4) This device adopts a design in which the wire cutting device and the wire stripping device share a positioning device. The first adjusting motor drives the second mounting box to move the two devices synchronously, and the second adjusting motor realizes the switching of the working modules. This design ensures that only one functional module is in the working position at the same time, which avoids interference between mechanisms and simplifies the complexity of the control system. Compared with the existing technology where each functional module is driven and positioned independently, this design significantly reduces the space occupied by the device, improves the coordination between each functional module, and makes the whole wire stripping process more compact and efficient. It is especially suitable for automated operation in high-altitude confined spaces.

[0029] (5) This application integrates the clamping device, decontamination device, ring cutting device, wire cutting device and wire stripping device into the same device body according to the predetermined working procedure and is equipped with a unified control system. This realizes full-process automation from positioning and clamping, surface cleaning, ring cutting operation, longitudinal cutting to insulation stripping. This highly integrated design overcomes the shortcomings of low efficiency of traditional manual wire stripping and single function of existing automated equipment, significantly improves work efficiency, and is particularly suitable for cable maintenance operations in harsh environments at high altitudes.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0045] Example:

[0046] This embodiment provides an automated stripping and connection device for overhead cables, which aims to solve the technical problem of surface contaminants affecting the quality of stripping and connection of overhead cables in high-altitude environments.

[0047] like Figure 1 ,and Figure 3 As shown, an automated stripping and connection device for overhead cables includes a main body with a symmetrical frame structure, comprising two oppositely arranged connection shells. The connection shells are cast from high-strength aluminum alloy, possessing sufficient structural strength and rigidity while maintaining a relatively light weight, facilitating installation and operation in high-altitude environments. The two connection shells are fixedly connected by several transverse connecting rods to form a stable working space.

[0048] Within the working space of the main body of the device, a clamping device and a circumferential cutting device are arranged sequentially along the cable axis. The clamping device is located on the outermost side of the main body of the device and is used to securely clamp and fix the cable at the beginning of the operation. The circumferential cutting device is located on the inner side of the clamping device and is used to make precise circumferential cuts on the cable insulation layer. In the working area between the two circumferential cutting devices, a decontamination device, a wire cutting device, and a wire stripping device are also slidably connected to the connecting shell. These devices enter the working position sequentially according to the predetermined working procedure to complete their respective specific functions.

[0049] Specifically, the clamping device includes a clamping drive motor, a clamping screw, a clamping slider, connecting rods, and V-shaped clamping blocks. The clamping screw is horizontally positioned in a plane parallel to the cable axis. The clamping slider forms a precise helical transmission pair with the clamping screw through an internal threaded hole. The thread structure of the threaded screw is symmetrically distributed, which causes the two opposing clamping sliders on the clamping screw to move in opposite directions. At the same time, the two sides of the clamping slider slide against the linear guide rails on the connecting shell to limit the slider movement, ensuring that the slider can only move linearly along the axial direction of the clamping screw. Connecting rods are fixedly connected to the ends of the clamping sliders, and the other ends of the connecting rods on both sides are connected to a V-shaped clamping block, thus forming a complete automated cable clamping system.

[0050] Based on the above settings, when the clamping drive motor starts, it drives the clamping screw to rotate, causing the clamping sliders on both sides to move closer to or away from the cable along the linear guide rail. The linear movement of the clamping sliders causes the two V-shaped clamping blocks to move synchronously toward or away from the center of the cable. This design ensures the symmetrical distribution of clamping force, avoids the cable from shifting or twisting during the clamping process, and achieves a stable clamping of the cable.

[0051] Furthermore, the working surface of the V-shaped clamping block is specially designed with anti-slip textures and a flexible pad embedded on its inner side. The anti-slip textures adopt an interlaced sawtooth structure, which can effectively increase the friction coefficient between the clamping block and the cable surface and prevent slippage during operation. The flexible pad is made of rubber material with a high coefficient of friction and has a certain compression deformation capacity, which can not only adapt to the clamping requirements of cables of different diameters, but also avoid mechanical damage to the cable insulation layer.

[0052] Specifically, the decontamination device includes a decontamination positioning mechanism and a decontamination cleaning mechanism. The decontamination positioning mechanism includes a decontamination positioning motor, a decontamination lead screw set at the output end of the decontamination positioning motor, a decontamination slider that is threadedly engaged with the decontamination lead screw, and a first mounting box fixedly connected to one end of the decontamination slider that extends out of the connecting shell. The decontamination slider and the first mounting box are connected by a connecting rod, which is restricted in a groove opened in the connecting shell, thereby limiting the decontamination slider to be able to move only along the axial direction.

[0053] The cleaning mechanism includes: a mounting plate housed in a first mounting box; several electromagnetic coils fixedly connected to the mounting plate; several permanent magnets surrounding the electromagnetic coils; two fixed connecting columns fixedly connected between the two mounting plates and offset from the center of the rotating plate; and two sliding connecting columns connected to the two fixed connecting columns on one side of the mounting plate offset from the center of the mounting plate by elastic telescopic members. Specifically, the permanent magnets are fixedly connected to the first mounting box, and the mounting plate is rotatably connected to the first mounting box. A cleaning sheet is wrapped between the two fixed connecting columns and the two sliding connecting columns. A cleaning positioning motor is used to drive the first mounting box to slide on the connecting shell for positioning. When the electromagnetic coils are energized, they generate a magnetic field that interacts with the permanent magnets, causing the mounting plate to rotate and perform cleaning treatment on the cable surface.

[0054] The clamping device is used to clamp the overhead cable. When the decontamination positioning motor drives the first mounting box to move closer to the cable, the decontamination plate surrounding the fixed connecting column and the sliding connecting column is pressed tightly against the cable. The sliding connecting column is compressed towards the fixed connecting column due to the obstruction of the cable, so that the decontamination plate is pressed tightly against the cable. When the electromagnetic coil is energized, the rotating disk drives the decontamination plate to rotate around the cable circumference to achieve decontamination of the cable surface. The decontamination plate is made of non-woven fabric, and its surface is firmly adhered with densely arranged nylon bristles. This design makes the decontamination plate both flexible enough to adapt to the curvature changes of the cable surface and has sufficient cleaning power to effectively remove various contaminants attached to the cable surface.

[0055] Based on the above setup, when the decontamination device is working, the decontamination positioning motor first drives the first mounting box to move towards the cable, causing the decontamination plates wrapped around the fixed connecting column and the sliding connecting column to gradually approach the cable surface. As the first mounting box continues to advance, the sliding connecting column first passes the cable. Under the reaction force of the cable, the sliding connecting column begins to compress the elastic telescopic component and retracts towards the fixed connecting column. This adaptive motion mechanism ensures that the two sliding connecting columns can automatically adjust their positions according to the actual diameter of the cable, so that the decontamination plates can tightly and evenly cover the entire circumference of the cable. After the decontamination plates completely cover the cable, the electromagnetic coil is energized, causing the mounting plate to rotate slowly. The entire decontamination plate assembly generates a rotating cleaning motion around the cable axis. During this process, the bristles on the surface of the decontamination plates generate relative motion with the cable surface, effectively brushing away contaminants such as dust, oxides, and salt crystals adhering to the cable surface.

[0056] Specifically, the circumferential cutting device includes a depth control mechanism and a circumferential cutting mechanism. The depth control mechanism includes a depth control motor, an open gear disk meshing with the output end of the depth control motor, several blade limiting members disposed at one end of the open gear disk, and a pressure feedback unit mounted on the blade limiting members. Several arc-shaped sliding rails are arranged circumferentially along the central axis of the open gear disk. Blade mounting rods are disposed at both ends passing through the arc-shaped sliding rails. One end of the blade mounting rod is slidably connected to the blade limiting member and is limited by the sliding motion of the blade limiting member. A circumferential cutting blade is fixedly connected to one end of the blade limiting member. When the depth control motor drives the open gear disk to rotate, the blade mounting rods move away from or closer to the central axis of the blade disk mounting plate due to the contact between the arc-shaped sliding rails and the blade limiting members, thereby controlling the cutting depth of the blade. Referring to existing technology, the pressure feedback unit includes a micro-force sensor and a signal processing circuit, which can monitor the resistance experienced by each circumferential cutting blade during the cutting process in real time and feed the signal back to the control system of the entire device. That is, the pressure feedback unit monitors the cutting force according to the sliding force of the blade mounting rod on the blade limiting member.

[0057] The circumferential cutting mechanism includes: a circumferential cutting drive disk rotatably connected to the connecting shell and having teeth on both its inner and outer ring surfaces; a circumferential cutting drive motor meshing with the outer gear surface of the circumferential cutting drive disk; and a planetary gear meshing between the inner gear surface of the circumferential cutting drive disk and the outer gear surface of the open gear disk. The depth control motor is fixedly connected to the circumferential cutting drive disk, and the blade limiting component is fixedly connected to the circumferential cutting drive disk. When the circumferential cutting drive motor is running, it drives the planetary gear and the open gear disk to rotate as a whole, thereby achieving circumferential cutting of the cable insulation layer.

[0058] Based on the above setup, when the circumcision device is working, the depth control motor starts operating, driving the cutter head mounting plate to rotate. Under the contact of the arc-shaped sliding rail and the blade limiting component, the blade mounting plate moves away from or closer to the central axis of the cutter head mounting plate, thus adjusting the cutting depth. Subsequently, the depth control motor stops rotating, and after the circumcision drive motor starts, it drives the circumcision drive plate to rotate. With the planetary gear setup, this drives the depth control motor, the open gear plate, and the circumcision blades with the set cutting depth to rotate around the cable axis for circumcision at both ends. During this process, because both the circumcision drive plate and the open gear plate are equipped with inlets for inserting the cable from one side, the rotation angle of the depth control motor and the circumcision drive motor is limited. However, due to the multiple circumcision blades, it is sufficient to ensure a complete circumcision around the cable. Simultaneously, the pressure feedback unit monitors the cutting resistance in real time, and the control system dynamically adjusts the feed amount of the depth control motor based on the feedback pressure signal, ensuring that the circumcision blades cut into the insulation layer with constant pressure. This closed-loop control mechanism can effectively compensate for minor changes in cable diameter and the inhomogeneity of the insulation material, ensuring that the depth of the circumcision cut remains consistent.

[0059] Specifically, the wire cutting device includes a wire cutting drive motor, a wire cutting screw located at the output end of the wire cutting drive motor, a wire cutting slider threadedly engaged with the wire cutting screw, and a wire cutting head fixedly connected to the wire cutting slider. The wire cutting drive motor drives the wire cutting head to move axially along the cable through the threaded wire cutting screw and the wire cutting slider, for longitudinal cutting between the annular cuts completed by the circumferential cutting device. The starting point of the wire cutting device is consistent with the circumferential cutting position of the circumferential cutting device.

[0060] Specifically, the wire stripping device includes a wire stripping drive motor, a wire stripping screw located at the output end of the wire stripping drive motor, a wire stripping slider threadedly engaged with the wire stripping screw, and a V-shaped wire stripping plate fixedly connected to the wire stripping slider; the wire stripping drive motor drives the V-shaped wire stripping plate to move along the cable axis, stripping the insulation segments that have been circumferentially cut and longitudinally cut from the cable conductor.

[0061] Furthermore, an adjustment device is also provided on one side of the connecting housing located on the cleaning device. The adjustment device includes: a second mounting box located on the side of the connecting housing away from the first mounting box; a first adjustment motor for driving the second mounting box away from or closer to the cable; and a second adjustment motor for adjusting the stripping device and the cutting device to move closer to or further away from the cable in the longitudinal direction to switch the working mode.

[0062] Based on the above setup, the wire cutting device and the wire stripping device share a set of adjustment devices. This design ensures that only one functional module is in the working position at any given time, avoiding interference between mechanisms and simplifying the complexity of the control system.

[0063] Working principle: First, the device is moved to the predetermined working position of the overhead cable by external transportation equipment (such as drones or robotic arms); the clamping device starts working first, the clamping drive motor drives the V-shaped clamping block to close through the lead screw, and firmly clamps the cable. During the clamping process, the control system monitors the clamping force in real time to ensure that it provides sufficient clamping stability while avoiding excessive compression of the cable.

[0064] After the cable is reliably secured, the decontamination device begins operation to remove surface contaminants. The decontamination positioning motor activates first, driving the first mounting box, along with the entire decontamination cleaning mechanism, towards the cable via a lead screw drive. When the decontamination plate, tensioned by the fixed and sliding connecting columns, contacts the cable, the sliding connecting column, under the cable's reaction force, compresses the elastic telescopic component, causing it to contract inwards. This adaptive mechanism ensures the decontamination plate tightly and evenly wraps around the circumference of cables of varying diameters. Subsequently, the electromagnetic coil is energized, and its generated magnetic field interacts with the circumferentially fixed permanent magnet, driving the mounting plate to rotate slowly, thereby causing the decontamination plate to perform circumferential brushing around the cable. During this rotational motion, the dense nylon bristles on the surface of the decontamination plate effectively scrape away contaminants, providing a clean working surface for subsequent cutting.

[0065] After surface cleaning is completed, the circumferential cutting device begins operation. First, the depth control motor starts, driving the opening gear disk to rotate slightly. This rotation is converted into synchronous radial feed of all blade mounting rods and their circumferential cutting blades through the arc-shaped sliding rail and blade limiting components, thereby accurately presetting the cutting depth. During this process, the pressure feedback unit integrated on the blade limiting components monitors the resistance of each blade in real time and feeds it back to the control system, dynamically adjusting the feed amount to ensure constant cutting pressure and effectively compensate for the unevenness of the insulation material and diameter. After the depth is set, the circumferential cutting drive motor starts, driving the circumferential cutting drive disk to rotate. The latter drives the entire opening gear disk and blade assembly to revolve around the cable axis once through meshing planetary gears, thereby completing a uniform and completely cut annular slit in the insulation layer.

[0066] After completing the circumferential cuts at both ends, the device performs longitudinal cutting to connect the circumferential cuts. The adjustment device first activates, precisely positioning the cutting device so that the starting point of its cutting head is aligned with the completed circumferential cut position. Subsequently, the cutting drive motor starts, driving the cutting slider carrying the cutting head through the cutting screw, making it move smoothly and precisely in a straight line along the cable axis. During the movement, the cutting head accurately cuts the insulation layer between the two circumferential cuts, forming a continuous longitudinal cutting line, which together with the circumferential cuts constitutes a complete "I"-shaped stripping path.

[0067] After the longitudinal cut is completed, the adjustment device works again to switch the stripping device to the working position, so that its V-shaped stripping blade moves and embeds into the end of the longitudinal cut of the insulation layer; the stripping drive motor then starts, driving the stripping slider and the V-shaped stripping blade to move along the cable axis through the stripping screw; as the V-shaped blade moves forward, it uses its wedge structure to insert into the gap between the insulation layer and the conductor, and relies on continuous axial force to pry up and peel off the entire section of insulation, finally completing the entire stripping process and preparing for cable connection;

[0068] Throughout the entire wire stripping process, the actions of each functional module are coordinated by the same control system. Precision sensors monitor the working status of each stage in real time, ensuring that the entire process is stable, reliable, and efficient.
