[0026] A leak-sensing cable, also known as a leak detection rope or leak detection line, is a safety device used for real-time monitoring of liquid leaks. It is typically used in conjunction with a controller to form a water immersion sensor, primarily for detecting liquid leaks in various environments.
[0027] The working principle of leakage induction wire is based on the principle of electrical conductivity. When using leakage induction wire, the outer braided shielding layer needs to be peeled off to expose the inner wire core, allowing the wire core to come into contact with the liquid, causing a change in current, thereby triggering the alarm system.
[0028] The most common method for stripping the insulation layer of existing leakage inductors is the mechanical splitting method. However, the mechanical splitting method may scratch the wire core, which poses a risk of leakage.
[0029] This invention proposes an insulation layer stripping system, which aims to achieve precision and safety in insulation layer stripping. By using high-precision laser stripping technology, it ensures that the insulation layer is completely removed while avoiding damage to the conductor inside the inductor, thus maintaining the functional integrity of the cable.
[0030] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the insulation layer stripping system 100 is used to strip the insulation layer of the leakage wire 1. The insulation layer stripping system 100 includes a base, a laser stripping component 2 and a clamping component. The laser stripping component 2 is movably disposed on the base and is used to emit a laser to the stripping position to strip the insulation layer. The clamping component is used to support and fix the leakage wire 1.
[0031] In this embodiment, the base serves as a rigid platform supporting all components of the system. Specifically, it can be implemented using a cast iron or welded steel frame, providing a stable mounting foundation for the equipment. The laser stripping assembly 2 is an optical device that generates the energy required for stripping. Specifically, it can be implemented using a carbon dioxide laser with a focusing lens group, and the stripping depth is controlled by adjusting the output power and the spot diameter. The clamping assembly is used to support and fix the leakage wire; its specific structure can be a mounting groove or a clamping mechanism.
[0032] During operation, the leakage sensing wire 1 is placed inside the clamping assembly, and the wire is fixed by a pneumatic or electric actuator or a snap-fit mechanism. The laser stripping assembly 2 moves along a preset path, and the emitted laser beam acts on the interface between the insulation layer and the wire core, causing a pyrolysis reaction in the polymer material. The spaced clamping points form a stable three-point support structure, effectively suppressing lateral displacement of the wire during processing and ensuring the accuracy of the laser's position.
[0033] The present invention provides an insulation layer stripping system 100 and method, which uses a laser stripping component 2 to strip the insulation layer non-contactly, and combines it with a clamping component to stably fix the leakage wire 1, avoiding damage to the wire core and stress caused by mechanical cutting. It has the advantages of avoiding scratching the wire core, improving stripping accuracy, preventing the insulation layer from spreading, and improving safety and versatility.
[0034] Specifically, in an embodiment of this utility model, the clamping component is a mounting groove, and the leakage sensing wire 1 is disposed in the mounting groove.
[0035] In this embodiment, the clamping component is a groove structure formed in the base, the size of which is adapted to the size of the leakage sensing wire 1 so that the leakage sensing wire 1 can be stably installed in the mounting groove for subsequent peeling operations.
[0036] Furthermore, in an embodiment of this utility model, the insulation layer peeling system 100 further includes two limiting blocks, which are disposed on the two side walls of the mounting groove.
[0037] In this embodiment, two additional limiting blocks are added inside the mounting groove. The connection between these limiting blocks and the sidewall of the mounting groove can be welding or integral design to ensure the stability of the connection. The two limiting blocks can provide additional fixation for the leakage sensing wire 1 from the side, further improving the installation stability of the leakage sensing wire 1.
[0038] In other embodiments of the present invention, the clamping assembly includes a first clamping assembly 31 and a second clamping assembly 32. The first clamping assembly 31 and the second clamping assembly 32 are spaced apart on the base along the extension direction of the leakage line 1, and the first clamping assembly 31 and the second clamping assembly 32 together clamp the leakage line 1.
[0039] In this embodiment, the base serves as a rigid platform supporting all components of the system. Specifically, it can be implemented using a cast iron or welded steel frame, providing a stable mounting foundation for the equipment. The laser stripping assembly 2 is an optical device that generates the energy required for stripping. Specifically, it can be implemented using a carbon dioxide laser with a focusing lens group, and the stripping depth is controlled by adjusting the output power and the spot diameter. The spacing in the clamping assembly is set so that the two clamping points maintain a predetermined distance along the wire axis. This can be achieved through a slide rail mechanism with a graduated scale, ensuring that the clamping spacing adapts to different wire specifications.
[0040] During operation, the leakage sensing wire 1 is placed between two clamping components, and the wire is fixed by a pneumatic or electric actuator. The laser stripping component 2 moves along a preset path, and the emitted laser beam acts on the interface between the insulation layer and the wire core, causing a pyrolysis reaction in the polymer material. The spaced clamping points form a stable three-point support structure, effectively suppressing lateral displacement of the wire during processing and ensuring the accuracy of the laser's position.
[0041] In other embodiments of the present invention, the first clamping assembly 31 includes a first base and a first clamping part. The first base is disposed on the base, and the first clamping part is disposed on the first base. The first clamping part is used to clamp the leakage wire 1.
[0042] The second clamping assembly 32 includes a second base and a second clamping part. The second base is disposed on the base, and the second clamping part is disposed on the second base. The second clamping part is used to clamp the leakage wire 1.
[0043] In this embodiment, when the leakage sensing wire 1 is placed on the base, the first clamping part and the second clamping part are spatially positioned by their respective bases. By independently controlling the clamping actions of the two clamping parts, both ends of the leakage sensing wire 1 are simultaneously clamped to form a two-point fixation. During the laser stripping process, the two clamping parts are rigidly connected to the base through the base, which can effectively resist the vibration generated by the laser impact and prevent the leakage sensing wire 1 from axially shifting or radially sliding.
[0044] In other embodiments of this utility model, both the first clamping part and the second clamping part are gripper cylinders.
[0045] In this embodiment, the gripper cylinder is a pneumatic actuator that drives the gripper to perform the gripping action via air pressure. Specifically, it can be implemented using a double-acting cylinder in conjunction with a gripper structure with adjustable stroke. The gripper cylinder controls the opening and closing of the gripper through an air circuit, enabling it to apply a uniform gripping force to the leakage sensing wire 1 during the gripping process. The gripping part is a mechanical structure that directly contacts and fixes the position of the leakage sensing wire 1; specifically, it can be implemented using a gripper surface with anti-slip texture. Driven by the gripper cylinder, the gripping part forms a closed space, ensuring the axial stability of the leakage sensing wire 1 during the peeling process.
[0046] In other embodiments of the present invention, the first clamping assembly 31 further includes a first driving part, which is connected between the first base and the first clamping part. The driving end of the first driving part drives the first clamping part so that the first clamping part can rotate in the circumferential direction of the leakage line 1.
[0047] In this embodiment, the first driving unit is a power device for controlling the movement of the clamping unit. Specifically, it can be implemented by a rotary motor. By driving the first clamping unit to rotate around the circumferential direction of the leakage wire 1, it is possible to perform a one-circumference cutting operation on the leakage wire 1, thereby improving the cutting efficiency.
[0048] In other embodiments of the present invention, the second clamping assembly 32 further includes a second driving part and a guide rail. The guide rail is disposed on the second base, and the second driving part drives the connection between the second clamping part and the guide rail so that the second clamping part can move along the extension direction of the guide rail.
[0049] In this embodiment, the guide rail is a guide structure mounted on the second base, which can be implemented using a linear guide rail or a ball screw structure. Its extension direction is parallel to the extension direction of the leakage sensing wire 1, providing a linear movement path for the second clamping part. The second drive unit is a power device that drives the movement of the second clamping part, which can be implemented using a servo motor or a pneumatic push rod, used to control the displacement of the second clamping part on the guide rail. Through the cooperation of the second drive unit and the guide rail, the second clamping part can move along the extension direction of the leakage sensing wire 1. After the stripping operation is completed, the second clamping part moves under the action of the second drive unit and the guide rail, taking the stripped insulation layer away from the leakage sensing wire 1 to expose the wire core, reducing manual operation and improving efficiency.
[0050] In other embodiments of the present invention, the insulation layer peeling system 100 further includes a control component 4, which is disposed on the base and electrically connected to the first driving part, the first clamping part, the second driving part, and the second clamping part.
[0051] In this embodiment, the control component 4 coordinates the rotation of the first clamping part driven by the first driving unit, the movement of the second clamping part along the guide rail driven by the second driving unit, and the clamping state of the clamping part on the leakage line 1 through a preset program. During the laser stripping process, the control component 4 synchronously adjusts the rotation angle and movement distance of the clamping part according to preset parameters, so that the leakage line 1 remains in a stable state at the stripping position.
[0052] In an embodiment of this utility model, the insulation layer stripping system 100 further includes a photo recognition component 5, which is electrically connected to the control component 4. The photo recognition component 5 is used to capture and recognize the location information of the leakage line 1 and transmit the location information to the control component 4.
[0053] In this embodiment, the image recognition component 5 is a device that acquires the surface and insulation layer status of the leakage wire 1 through an image acquisition device. Specifically, it can be implemented using an industrial camera combined with image processing algorithms to capture the spatial coordinates of the leakage wire 1 and the morphological features of the stripping area in real time. The control component 4 is an electronic module that receives and processes external signals. Specifically, it can be implemented using an embedded controller or a PLC system to adjust the movement trajectory of the laser stripping component 2 according to the position information.
[0054] In an embodiment of this utility model, the insulating layer has a braided structure;
[0055] The leakage line 1 also includes a braided layer, which is a braided structure and is located outside the insulation layer;
[0056] The laser ablation component 2 is a carbon dioxide laser.
[0057] In this embodiment, the braided structure is a layered structure formed by cross-weaving of fibers. Specifically, it can be achieved using materials such as polyester fibers. This structure has loose and porous characteristics, facilitating the penetration of laser energy through the outer layer and focusing it onto the insulating layer. The braided layer is a protective layer covering the outside of the insulating layer, and can be made of a plastic woven mesh, serving a protective function. The carbon dioxide laser is a mid-infrared laser device with an output wavelength of 10.6 micrometers. Specifically, it can be implemented using a radio frequency excited sealed laser tube. Using the carbon dioxide laser to cut the insulating layer and the braided layer allows for simultaneous cutting and fusing of the insulating layer and the braided layer, preventing the braid from unraveling.
[0058] In an embodiment of this utility model, the insulation peeling system 100 further includes a quality detection component 6, which is disposed on the base and is used to detect the state of the wire core and whether the insulation layer has spread out at the peeling position.
[0059] In this embodiment, after the laser stripping assembly 2 completes the insulation layer removal, the quality inspection assembly 6 scans the stripped area. The core condition detection module acquires core surface information through the image acquisition unit. If scratches or deformation are detected, an alarm is triggered and the process is paused. The insulation layer loosening detection module analyzes the morphological characteristics of the insulation layer edge. If loose or residual fibers are identified, the stripping is deemed incomplete. The detection results are fed back to the control assembly 4 in real time to determine whether secondary processing or adjustment of the stripping parameters is necessary.
[0060] In an embodiment of this utility model, the insulation layer peeling system 100 further includes a melting component 7, which is disposed on the base and is used to melt the dispersed insulation layer into a single unit for secondary processing.
[0061] In this embodiment, when the quality inspection component 6 detects that the insulation layer has spread at the peeling location, the melting component 7 is activated and performs targeted heating on that area. For example, when the remaining insulation fibers are dispersed after the core is exposed, the melting component 7 moves around the core in a circular path, and remelts the dispersed insulation material through thermal radiation to form a continuous wrapping layer. Furthermore, the operating parameters of the melting component 7 can be automatically adjusted according to the insulation layer thickness. For example, for a multi-layer braided insulation layer, a staged gradient heating operation can be implemented.
[0062] In the embodiments of this utility model, the internal cores of the leakage sensing wire 1 after stripping are in a bonded state.
[0063] In this embodiment, the cores inside the stripped leakage wire 1 are closely attached to each other, preventing them from coming apart and causing poor contact, while also preventing damage to the conductor and saving processing costs.
[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
