Description

Technical Field

[0001] This invention relates to the field of power component processing technology, specifically to an adaptive anti-damage peeling device for indoor power facility installation. Background Technology

[0002] In indoor electrical installation, cable stripping is a crucial step in ensuring reliable cable connections and stable electrical performance. With the increasing intelligence and sophistication of power systems, the requirements for cable stripping quality are becoming increasingly stringent. It's not enough to simply strip the insulation layer efficiently; damage to the copper core, shielding layer, and other internal structures must be avoided to accommodate complex and varied indoor wiring scenarios, such as confined spaces in ceilings or environments with numerous cables running through conduits. However, traditional stripping devices have significant shortcomings in structural design and functional adaptability, making it difficult to meet the high precision and adaptability demands of modern indoor electrical installation.

[0003] Traditional cable stripping devices often employ rigid clamping structures, using simple lead screws and sliders to fix cables. However, these structures have poor adaptability to cables of different diameters, and manual adjustment is time-consuming and inaccurate. During clamping, the movable mounting bracket is prone to shaking, causing the perpendicularity deviation between the cable axis and the stripping component to exceed the range. This leads to misalignment during insulation cutting and stripping, resulting in cable damage. Furthermore, there is a lack of effective means to adjust the cable's torsion state and axial straightness. When dealing with multi-core shielded cables or thin-walled cables, stress concentration can easily cause problems such as shielding layer breakage and loosening of the wire cores. Summary of the Invention

The front and rear sides of the surface of the drive screw are provided with external threads with opposite directions, and the interiors of the two drive sliders are respectively connected to the front and rear threads of the surface of the drive screw.

[0007] Furthermore, the top left and right sides of the peeling base are provided with sliding grooves that cooperate with the connecting sliders, and the bottoms of the two connecting sliders are respectively slidably connected to the inside of the two sliding grooves.

[0008] Furthermore, both of the peeling fixing brackets have semi-circular grooves inside, and when the opposite sides of the two peeling fixing brackets are attached, the two semi-circular grooves form a complete circular groove.

[0009] Furthermore, the peeling assembly includes an internal toothed groove located in the middle of the inner wall of the peeling fixing frame and a drive block slidably disposed inside the internal toothed groove. A drive gear is rotatably disposed at the bottom of the drive block, and one end of the drive gear is driven to rotate by a servo motor built into the drive block. A servo electric cylinder is fixedly disposed inside the drive block, and three servo electric cylinders are disposed inside the internal toothed groove of the drive block.

[0010] Furthermore, the detector includes a detection frame, and the detection frame is fixedly installed at one end of the drive shaft of the servo electric cylinder. A detection groove is provided on one side of the detection frame, and a shape memory alloy skeleton is fixedly installed on one side of the inner wall of the detection groove. A copper foil layer is also fixedly installed on one side of the shape memory alloy skeleton.

[0011] Furthermore, several servo electric cylinders are fixedly installed on both the left and right sides of the inner wall of the peeling and fixing frame, and the several servo electric cylinders are distributed at equal angles on the inner wall of the peeling and fixing frame. A cable clamping block is fixedly installed at the top of the drive shaft of each of the several servo electric cylinders. The cable clamping block includes a connecting block.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Example 1: Please refer to Figures 1 to 6 As shown, an adaptive anti-injury peeling device for indoor electrical facility installation includes: The peeling base 1 has two movable mounting brackets 2 symmetrically slidably mounted on the front and rear sides of its top. A drive slider 5 is fixedly mounted at the center of the bottom of each of the two movable mounting brackets 2, and connecting sliders 7 are fixedly mounted on both sides of the bottom of each of the two movable mounting brackets 2. A drive groove 3 is also provided in the center of the top of the peeling base 1, and a drive screw 4 is rotatably mounted inside the drive groove 3. One end of the drive screw 4 is driven by a servo motor built into the peeling base 1. The bottoms of the two drive sliders 5 are slidably connected inside the drive groove 3, and each drive slider 5 has an internal threaded hole that mates with the drive screw 4. The front and rear sides of the surface of the drive screw 4 have external threads with opposite directions, and the interiors of the two drive sliders 5 are respectively connected to the front and rear threads of the surface of the drive screw 4. When the drive screw 4 is driven to rotate clockwise by the servo motor built into the peeling base 1, the two drive sliders 5 slide relative to each other along the drive screw 4 inside the drive groove 3; conversely, the two drive sliders 5 slide in opposite directions along the drive screw 4 inside the drive groove 3. The top left and right sides of the peeling base 1 are also provided with sliding grooves 6 that cooperate with the connecting sliders 7, and the bottoms of the two connecting sliders 7 are respectively slidably connected to the inside of the two sliding grooves 6. The two connecting sliders 7 at the bottom of the movable mounting frame 2 slide inside the sliding grooves 6 to ensure the stability of the movable mounting frame 2 during the sliding process.

[0021] It should be noted that by using the opposite external threads on the surface of the drive screw 4, in conjunction with the internal threaded hole of the drive slider 5, the two movable mounting brackets 2 can slide precisely relative to each other or back to back under the drive of the servo motor. This allows for quick adaptation to clamping power facility cables of different diameters, eliminating the need for frequent manual adjustments and effectively improving operational efficiency. This solves the problems of time-consuming and inaccurate traditional manual adjustments.

[0022] The connecting slider 7 at the bottom of the movable mounting bracket 2 is embedded in the sliding groove 6 of the stripping base 1 to form a double-rail guide, which controls the amount of shaking of the movable mounting bracket 2 during sliding within ±0.1mm, ensuring that the perpendicularity error between the cable axis and the stripping component during clamping is ≤0.5°, ensuring stripping accuracy, and avoiding cable damage caused by shaking.

[0023] The stripping fixing frame 11 is fixedly installed in the middle of the opposite side of the two movable mounting frames 2, and the stripping fixing frame 11 is provided with stripping components inside the two stripping fixing frames 11. The interior of the two stripping fixing frames 11 is provided with semi-circular grooves, and when the opposite sides of the two stripping fixing frames 11 are attached, the two semi-circular grooves form a complete circular groove. When stripping the cables of power facilities, the cables are placed between the two stripping fixing frames 11, and the two movable mounting frames 2 are controlled to move relative to each other, so that the outer surface of the cables is covered by the two stripping fixing frames 11.

[0024] It should be noted that the two stripping fixing brackets 11 form a complete circular groove after they are attached together. The inner wall adopts an adaptive structure, which can closely fit the outer surface of the cable, providing stable support for the stripping operation, controlling the insulation layer indentation depth to ≤0.05mm, reducing the risk of damage caused by cable loosening, and solving the problem of stress concentration in traditional clamping.

[0025] The positioning connection frame 12 is movably mounted on the left and right sides of the two movable mounting frames 2 on opposite sides. An adjusting slider 10 is fixedly mounted on one side of each of the two positioning connection frames 12. An adjusting groove 8 is provided on the opposite side of each of the two movable mounting frames 2, and an adjusting screw 9 is rotatably mounted inside each adjusting groove 8. Both adjusting screws 9 are driven by a servo motor built into the movable mounting frame 2. One side of the adjusting slider 10 is slidably connected to the inside of the adjusting groove 8, and the inside of the adjusting slider 10 is threadedly connected to the surface of the adjusting screw 9. The positioning connection frame 12 also contains auxiliary components for straightening and stripping the cable stripping area on both sides.

[0026] It should be noted that the servo motor drives the adjusting screw 9 to rotate, which in turn moves the adjusting slider 10 within the adjusting groove 8, flexibly controlling the position of the positioning connecting frame 12. Its built-in auxiliary components can apply a 0.1-2N straightening tension to both sides of the cable stripping area, thereby improving the uniformity of the shielding layer unfolding, preventing the cable from twisting or deforming during stripping, and ensuring the quality and safety of stripping.

[0027] Furthermore, the peeling assembly includes an internal toothed groove 13 located in the middle of the inner wall of the peeling fixing frame 11 and a drive block 14 slidably disposed inside the internal toothed groove 13. A drive gear 15 is rotatably disposed at the bottom of the drive block 14, and one end of the drive gear 15 is driven to rotate by a servo motor built into the drive block 14. A servo electric cylinder 16 is fixedly disposed inside the drive block 14, and three servo electric cylinders 16 are disposed inside the internal toothed groove 13. A peeling knife 17, a laser cutter 18, and a detector 19 are respectively fixedly disposed at the drive ends of the three servo electric cylinders 16. The detector 19 includes a detection frame 20. The detection frame 20 is fixedly disposed at one end of the drive shaft of the servo electric cylinder 16, and a detection groove 21 is disposed on one side of the detection frame 20. A laser cutter 18 is fixedly disposed on one side of the inner wall of the detection groove 21. The shape memory alloy skeleton 22 has a copper foil layer 23 fixedly disposed on one side. A detection gap of 0.5 mm is provided between one side of the copper foil layer 23 and the outer side of the detection groove 21. The copper foil layer 23 is made of electrolytic copper foil with a thickness of 50 μm and a surface roughness of less than 0.5 μm. As the electrode body for capacitance detection, the shape memory alloy skeleton 22 is made of Ti-Ni-Cu alloy sheet with a thickness of 0.3 mm, which is laser-cut into an arc structure. Its inner side is bonded to the copper foil layer 23 with thermally conductive silicone grease to ensure that heat is quickly conducted to the copper foil during heating and to avoid deformation lag caused by temperature difference. At the same time, an insulating coating is provided on the inner surface of the detection groove 21. The insulating coating is made of polyimide film to prevent the shape memory alloy skeleton 22 from short-circuiting with the external circuit.

[0028] Furthermore, several servo cylinders 24 are fixedly installed on both the left and right sides of the inner wall of the stripping and fixing frame 11. These servo cylinders 24 are equidistantly distributed on the inner wall of the stripping and fixing frame 11. A cable clamping block 25 is fixedly installed at the top of the drive shaft of each servo cylinder 24. The cable clamping block 25 includes a connecting block 26. A connecting block 26 is fixedly installed at the top of the drive shaft of each servo cylinder 24. A shape memory alloy skeleton 27 is fixedly installed on one side of the connecting block 26. A hydraulic joint layer 28 is fixedly installed on one side of the shape memory alloy skeleton 27. A clamping gel layer 29 is also fixedly installed on one side of the hydraulic joint layer 28. The clamping gel layer 29 is made of temperature-sensitive PU material. The hydraulic joint layer 28 consists of six sets of micro-cylinders used to drive the clamping gel layer 29 to deform. The clamping force of the power cable can be precisely adjusted, and a pressure sensor is also installed inside the clamping gel layer 29 to monitor the contact pressure between the inner gel layer and the power cable in real time. When clamping a multi-core shielded cable, the hydraulic system can independently adjust the pressure of each joint, so as to improve the uniformity of the stress on the insulation layer of the power cable during the stripping process. The clamping gel layer 29 and the hydraulic joint layer 28 are fixed with medical-grade silicone adhesive to ensure that the hydraulic driving force is evenly transmitted to the clamping gel layer 29, while allowing the clamping gel layer 29 to produce elastic deformation of 0.5-1mm under pressure, avoiding stress concentration caused by rigid connection. The hydraulic joint layer 28 and the shape memory alloy skeleton 27 are connected by a flexible metal bellows, which can transmit the electric cylinder driving force and allow the skeleton to bend freely when heated and deformed.

[0029] It should be noted that during the stripping process of power cables, after the power cable is wrapped between two stripping fixing frames 11, the two sides of the power cable are straightened. Then, the servo electric cylinders 24 on both sides of the inner wall of the stripping fixing frame 11, together with the cable clamping block 25, are used to clamp the two sides of the stripped area of ​​the power cable. The clamping gel layer 29 is in direct contact with the surface of the insulation layer of the power cable to flexibly clamp the two sides of the stripped area of ​​the power cable. Then, the drive block 14, together with the servo electric cylinder 16, drives the detector 19 to clamp the power cable. The insulation layer thickness is monitored in a ring. The drive shaft of the servo cylinder 16 controls the detection frame 20 to approach the surface of the power cable. One side of the detection frame 20 contacts the insulation layer surface of the power cable. At the same time, the curvature of the copper foil layer 23 is adjusted according to the curvature of the power cable. By energizing the shape memory alloy skeleton 22, the shape memory alloy skeleton 22 drives the copper foil layer 23 to change the curvature. Then, the drive gear 15 meshes and drives the copper foil layer 23 to perform a ring detection on the insulation layer thickness of the power cable.

[0030] Specifically, the method for testing the thickness of the insulation layer of power cables is as follows: the relative permittivity of the insulation material of the power cables is calibrated in advance. PE≈2.3, PVC≈3.5; Obtain the contact area of ​​the electrolytic copper foil in copper foil layer 23. The total capacitance is measured and collected through the sensor circuit. ,pass The thickness of the insulation layer of the power cable was calculated. , is the vacuum permittivity.

[0031] In one specific embodiment, by controlling the drive block 14 to slide along the inner tooth groove 13, in conjunction with the servo motor drive of the drive gear 15, the circumferential positioning of the stripping tool can be precisely achieved, with a positioning accuracy of ±0.5mm. This ensures that the stripping blade 17, laser cutter 18, and detector 19 cover the entire circumference of the cable as needed, adapting to the stripping requirements of cables of different diameters. The drive gear 15 is driven by the servo motor built into the drive block 14, meshing and rotating along the inner tooth groove 13, providing stable circumferential power to the drive block 14, thus enabling the tool switching and positioning process to be precise. Vibration ≤0.1mm ensures the accuracy of laser cutting and capacitance detection; servo electric cylinder 16 drives peeling knife 17, laser cutter 18, and detector 19 to extend and retract as needed, realizing an automated process of "detection → cutting → peeling": detector 19 first obtains the insulation layer thickness by capacitance detection between shape memory alloy skeleton 22 and copper foil layer 23; laser cutter 18 pre-cuts the insulation layer with a power of 5-30W according to the detection data; finally, peeling knife 17 completes the peeling, avoiding errors and efficiency losses caused by manual tool switching.

[0032] The shape memory alloy skeleton 22 and copper foil layer 23 inside the testing frame 20 are bonded by thermally conductive silicone grease and polyimide insulating coating to achieve non-destructive thickness measurement by capacitance method. The 50μm electrolytic copper foil and ≤0.5μm roughness of the copper foil layer 23 ensure the uniformity of the air gap, so that the insulation layer thickness detection error is ≤±0.03mm, and the risk of overcut / undercut is warned in advance. The servo electric cylinder 24 drives the cable clamping blocks 25 to clamp at equal angles. Through the thermal deformation of the shape memory alloy skeleton 27 and the pressure closed-loop control of the hydraulic joint layer 28, combined with the temperature-sensitive buffer of the clamping gel layer 29, the uniformity of force on the cable insulation layer is improved by 70%, and the indentation depth is ≤0.05mm, avoiding shielding layer breakage and wire core loosening caused by rigid clamping.

[0033] Example 2: Specifically, this example also discloses the specific structure of the auxiliary component: the auxiliary component includes a rotating frame 30, which is rotatably mounted inside the positioning connecting frame 12, and a rotary motor for driving the rotating frame 30 to rotate is fixedly mounted on one side of the positioning connecting frame 12. The rotating frame 30 has an external tooth groove on its outer side, and a drive gear is fixedly mounted on the output shaft of the rotary motor. The tooth surface of the drive gear meshes with the external tooth groove on the outer side of the rotating frame 30. A plurality of servo electric cylinders 31 are fixedly mounted on the inner wall of the rotating frame 30, and the plurality of servo electric cylinders 31 are arranged at equal angles. Adsorption blocks 32 and peeling knives 33 are fixedly mounted on the driving ends of two adjacent servo electric cylinders 31, respectively. Therefore, adsorption blocks 32 and peeling knives 33 are spaced apart at the driving ends of the plurality of servo electric cylinders 31.

[0034] It should be noted that the blade direction of the second stripper 33 is horizontal with respect to the cable. The second stripper 33 is used to perform horizontal cutting of the cable, while the first stripper 17 and the laser cutter 18 are both used to perform circular cutting of the cable. When stripping the insulation of power cables, the power cables are attracted and positioned by the suction blocks 32 on both sides. The adjusting screw 9 controls the two positioning connecting frames 12 to move to both sides to straighten the power cables to be stripped. The rotating frame 30 is controlled to rotate to adjust the twisting state of the power cables and ensure that the power cables are in a straight state. The detector 19 comprehensively detects the thickness of the insulation layer of the power cables to be stripped. Then, the laser cutter 18 first performs a circumferential cut on the cutting area of ​​the power cables. After the laser cut, a 5mm cutting allowance is left on the power cables. The stripping knife 17 is then used to completely cut off the cutting allowance. Finally, the stripping knife 33 on the positioning connecting frame 12 slides and cuts the power cables to the side where they are to be stripped. At this time, the suction blocks 32 only provide a sliding limit function and do not provide an adsorption positioning function. The surface of the power cable is transversely cut by several stripping blades 33 until one end of the power cable is cut, and the insulation layer of the stripped area on the power cable is cut into several strip-shaped insulation layers, thus completing the non-destructive stripping process of the power cable.

[0035] In one specific embodiment, the rotating frame 30 of the present invention is driven by a rotary motor. Through the meshing transmission of the drive gear and the external tooth groove, the rotating frame 30 can rotate ±180°, which can dynamically adjust the cable twist state. Combined with the straightening function of the adsorption block 32, the cable twist amount is corrected from ≤5mm to ≤1mm, ensuring the axial consistency of laser cutting and stripping operations. The servo electric cylinders 31, which are distributed at equal angles, drive the adsorption block 32 and the stripping blade 33 to extend and retract at intervals, realizing the streamlined operation of "adsorption positioning → cross-cutting stripping". The extension and retraction response time of the electric cylinders is ≤50ms, ensuring the synchronization of tool switching and cable movement, and avoiding cutting deviation caused by delay.

[0036] The adsorption block 32 uses negative pressure to adsorb and fix the cable, and in conjunction with the adjusting screw 9, it drives the positioning connecting frame 12 to move to both sides, providing 0.5-2N axial tension to the area to be stripped, so that the axial straightness error of the cable is ≤0.2mm / m, ensuring the path accuracy of the ring cutting and cross cutting.

[0037] The blade is horizontally attached to the cable and achieves circumferential transverse cutting under the drive of the rotating frame 30, dividing the insulation layer into several strips. Combined with the 5mm cutting allowance of laser cutting and the complete cutting of the stripping blade, the peeling force of the insulation layer is reduced by 30%, avoiding the pulling of the shielding layer caused by traditional whole-circle peeling.

[0038] Example 3: Specifically, this example discloses the working method of an adaptive anti-damage peeling device for indoor power facility installation, including the following steps: Step 1: Start the built-in servo motor of the stripping base 1 to drive the drive screw 4 to rotate. Because the external threads on the front and rear sides of the drive screw 4 rotate in opposite directions, they cooperate with the internal thread hole of the drive slider 5 to make the two movable mounting brackets 2 slide relative to each other / backward along the drive groove 3. At the same time, the bottom connecting slider 7 of the movable mounting bracket 2 slides in the sliding groove 6 to form a double-rail guide, controlling the wobbling of the movable mounting bracket 2 within ±0.1mm to ensure subsequent clamping accuracy. Adjust the distance between the two movable mounting brackets 2 according to the cable diameter to adapt to the cable specifications. Step 2: Place the power cable between the two stripping and fixing brackets 11, control the relative movement of the movable mounting bracket 2 so that the two stripping and fixing brackets 11 fit together, and their semi-circular grooves form a complete circular groove to cover the cable. Then, the servo electric cylinder 24 on the inner wall of the stripping and fixing bracket 11 drives the cable clamping block 25 to extend, and uses the clamping gel layer 29 to contact the cable insulation layer. The hydraulic joint layer 28 independently adjusts the pressure of each joint according to the feedback of the pressure sensor. Step 3: On the movable mounting bracket 2, the adjusting screw 9 is driven to rotate by the built-in servo motor, which moves the adjusting slider 10 within the adjusting groove 8 to adjust the position of the positioning connecting bracket 12. The rotating motor inside the positioning connecting bracket 12 starts, and the driving gear meshes with the outer tooth groove of the rotating bracket 30, causing the rotating bracket 30 to rotate. With the help of the suction block 32, the negative pressure suction moves the positioning connecting bracket 12 to both sides, providing 0.5-2N axial tension to the area of ​​the cable to be stripped, correcting the cable twist from ≤5mm to ≤1mm, straightening the cable and adjusting the twist state to ensure the subsequent cutting accuracy. Step 4: The drive block 14 slides along the inner tooth groove 13 of the stripping fixing frame 11. The drive block 14 has a built-in servo motor that drives the drive gear 15, which meshes with the inner tooth groove 13 to achieve precise circumferential positioning. The servo electric cylinder 16 drives the detector 19 to approach the cable. One side of the detection frame 20 contacts the cable insulation layer. By energizing the shape memory alloy skeleton 22, it drives the copper foil layer 23 to adapt to the cable curvature. Using the capacitance detection principle, the insulation layer thickness is detected with an error of ≤ ±0.03mm, and the risk of overcutting / undercutting is warned. Step 5: Based on the detection data of detector 19, servo cylinder 16 drives laser cutter 18 to extend and perform circumferential cutting on the cable cutting area with a power of 5-30W, leaving a 5mm cutting allowance; then drive stripping blade 17 to extend and completely cut off the cutting allowance to complete the circumferential cutting process. Drive block 14 moves along inner tooth groove 13 to ensure that the cutting tool covers the cable circumferentially. Drive gear 15 drives the tool to switch and position vibration ≤0.1mm to ensure cutting accuracy. Step 6: The servo cylinder 31 inside the positioning connector 12 drives the stripping blade 33 to extend, with its blade horizontally aligned with the cable. The rotating frame 30 rotates, causing the stripping blade 33 to make a circumferential cut, dividing the insulation layer into several strips. Combined with the ring cut to leave a margin and completely cut off, the peeling force of the insulation layer is reduced, completing the stripping without damage. This method is suitable for stripping complex cable structures such as multi-core shielded cables and thin-walled cables.
