Abstract
Description
Technical Field
[0001] This invention belongs to the field of metal wire processing technology, and particularly relates to equipment and method for peeling off the coating of amorphous alloy wires. Background Technology
[0002] Currently, with the increasing demand for high-precision magnetic field detection technology in the fields of IoT, smart sensing, aerospace, and industrial inspection, giant magnetoresistance (GMI) sensors have become core components in this field due to their unique technological advantages. Compared with traditional magnetic field detection devices such as Hall sensors and fluxgate sensors, GMI sensors have outstanding advantages such as high sensitivity (magnetic field resolution up to the nT level), fast response speed (microsecond-level response time), low power consumption, small size, and strong anti-interference ability. They can be widely used in geomagnetic navigation, non-destructive testing, biomedical magnetic signal monitoring, smart grid current detection, and other fields.
[0003] The core sensing material of GMI sensors is amorphous alloy wire. The disordered microstructure of this wire endows it with excellent magnetic properties, which is the core foundation for ensuring the sensor's high sensitivity and stability. Among the various methods for preparing amorphous alloy wire, glass coating is currently the mainstream approach.
[0004] However, a dense and insulating glass cladding layer adheres to the surface of amorphous alloy wires prepared by the glass-cladding method. While this layer protects the wire's morphology and prevents oxidation during fabrication, it becomes a key technical bottleneck restricting its application in GMI sensors. This is because the glass cladding layer blocks effective conduction between the amorphous alloy wire and external electrodes, affecting magnetic signal transmission and induction, significantly reducing the detection accuracy and response efficiency of the GMI sensor. Therefore, precise removal of the glass cladding layer is necessary to enable the functional application of the amorphous alloy wire. Currently, the mainstream method for removing the glass cladding layer in the industry is chemical etching, which uses hydrofluoric acid to etch and peel off the glass layer.
[0005] However, this method has the following drawbacks: Hydrofluoric acid is a highly dangerous and corrosive reagent with extreme toxicity and strong permeability. It not only poses extremely high safety hazards during storage, transportation, and operation, but also easily causes irreversible damage to the health of operators and seriously pollutes the production environment, failing to meet the requirements of green and safe industrial production. Furthermore, the degree of corrosion is difficult to control precisely during the hydrofluoric acid etching process, which can easily cause chemical damage to the surface of the amorphous alloy wire, leading to a decrease in the magnetic properties of the amorphous alloy wire and even wire breakage, thus reducing the yield of finished products and the stability of sensor devices. Summary of the Invention
[0006] The purpose of this application is to provide a device for peeling off the coating layer on amorphous alloy wires, aiming to solve the problem of how to remove the coating layer on amorphous alloy wires and improve safety and reliability.
[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, this application provides a peeling device for amorphous alloy wire cladding, used for processing wire bodies, the wire body comprising a wire core and a cladding layer covering the wire core and made of a brittle material, the peeling device for amorphous alloy wire cladding comprising: A vibration structure includes a vibrating head, a support platform located below the vibrating head, and a vibration generator for driving the vibrating head to reciprocate vertically; and The winding structure includes a drive assembly, a feed roller on which the wire is wound, and a winding roller spaced apart from the feed roller. Both the feed roller and the winding roller are rotatable. The drive assembly is used to drive the feed roller and the winding roller to rotate synchronously. The support platform is located between the unloading wheel and the winding wheel. During rotation, the unloading wheel releases the wire onto the support platform. The vibration generator drives the vibration head to abut against and break the coating layer of the wire on the support platform, so that the wire core can be wound onto the winding wheel. In some embodiments, the feeding roller, the support platform, and the winding roller are arranged linearly and at intervals in the horizontal direction, and the support platform has an upward-facing support surface for supporting the wire body.
[0008] In some embodiments, the support surface is arranged horizontally, and the highest point of both the winding reel and the unwinding reel is located on the horizontal plane defined by the support surface.
[0009] In some embodiments, the support surface is arranged in the form of a convex arc surface, the line is supported at the apex of the convex arc surface, and the apex of the convex arc surface, the highest point of the winding wheel and the highest point of the unwinding wheel are all located on the same horizontal plane.
[0010] In some embodiments, the drive assembly includes two rotating shafts, two worm gears, a worm, and a rotary driver for driving the worm to rotate. The two rotating shafts are respectively connected to the feed wheel and the winding wheel, and the two worm gears are respectively connected to the two rotating shafts and are both engaged with the worm.
[0011] In some embodiments, the drive assembly further includes a fixed plate and a fixed seat disposed on the fixed plate and having a rotating groove. Two fixed seats are arranged at intervals along the axial direction of the worm. Two rotating shafts are rotatably connected to the two fixed seats respectively. Two worm wheels are located in the two rotating grooves respectively. The support platform is connected to the fixed plate.
[0012] In some embodiments, the device for peeling off the coating layer of amorphous alloy wire further includes a position adjustment structure. Two position adjustment structures are stacked in a vertical direction. The two position adjustment structures are used to drive the fixing plate to move along a first direction and a second direction, respectively. The first direction is orthogonal to the second direction. The fixing plate is connected to the position adjustment structure located above.
[0013] In some embodiments, the vibration structure further includes an adjustment plate, an adjustment seat connected to the adjustment plate, guide posts fixedly arranged in the vertical direction, and guide sleeves slidably connected to the guide posts. Multiple guide posts are spaced apart, and each guide post is provided with a guide sleeve. Each guide sleeve is arranged circumferentially along the adjustment plate and connected to the adjustment plate. The vibration structure also includes an adjustment driver disposed on a positioning plate spaced apart from the adjustment plate in the vertical direction. The positioning plate is connected to each guide post, and the two ends of the adjustment seat are respectively connected to the vibration generator and the adjustment driver.
[0014] Secondly, this application also provides a peeling method using the aforementioned peeling equipment for amorphous alloy wire coatings, the peeling method comprising the following steps: Prepare a vibration structure and a winding structure, and place the vibration head directly above the support platform, and connect the vibration head to the output shaft of the vibration generator; The wire to be stripped is wound around the unwinding wheel, and one end of the wire is stretched across the support platform and connected to the winding wheel, so that the support platform supports the portion of the wire located on the unwinding wheel and the winding wheel; The vibration generator drives the vibration head to abut against the cladding layer and apply a predetermined value of shear stress to the cladding layer to break and remove the cladding layer and expose the wire core at the corresponding position; The drive assembly drives the unloading wheel and the winding wheel to rotate synchronously, so that the unloading wheel releases the wire to be stripped onto the support platform and the exposed wire core is wound around the winding wheel.
[0015] In some embodiments, the shear stress is less than the yield strength of the wire core and greater than the adhesion between the cladding layer and the wire core.
[0016] The beneficial effects of this application are as follows: By combining the vibration structure and the winding structure, and utilizing the difference in elastic modulus and thermal expansion properties between the flexible core and the brittle sheath, a vibration generator drives a vibrating head to vibrate at high frequency. This allows the vibrating head to continuously and precisely impact the sheath, causing it to break and detach from the core. During this breaking process, the vibrating head does not contact the core, thus preventing damage. Furthermore, the detachment of the sheath from the core eliminates the need for hazardous, highly polluting, and difficult-to-control hydrofluoric acid, improving the safety, reliability, and environmental friendliness of the processing.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of this application.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.
[0022] Please see Figures 1 to 3This application provides an amorphous alloy wire cladding layer peeling device 100 and a peeling method. The amorphous alloy wire cladding layer peeling device 100 is used to peel the wire body. The wire body includes a wire core made of flexible and conductive material and a cladding layer covering the wire core made of brittle material. In this embodiment, the wire core can be an amorphous alloy wire, which can be iron-based amorphous alloy wire, cobalt-based amorphous alloy wire, or nickel-based amorphous alloy wire, etc., and is not limited here; it can be selected according to the actual situation. The diameter of the wire core ranges from 1 to 100 μm, the material of the cladding layer can be borosilicate glass or high borosilicate glass, and the thickness of the cladding layer ranges from 0.5 to 50 μm.
[0023] The device 100 for peeling off the coating of amorphous alloy wire includes a vibration structure 10 and a winding structure 20.
[0024] Please see Figures 1 to 3 The vibration structure 10 includes a vibration head 14, a support platform 15 located below the vibration head 14, and a vibration generator 11 for driving the vibration head 14 to reciprocate in the vertical direction. It is understood that the vibration head 14 is located directly above the support platform 15, and the vibration generator 11 can drive the vibration head 14 to reciprocate in the vertical direction, causing the vibration head 14 to move closer to and away from the support platform 15. The vertical direction can be represented as Z.
[0025] The winding structure 20 includes a drive assembly 23, a feed roller 21 on which the wire is wound, and a winding roller 22 spaced apart from the feed roller 21. Both the feed roller 21 and the winding roller 22 are rotatably arranged. The drive assembly 23 is used to drive the feed roller 21 and the winding roller 22 to rotate synchronously, and the feed roller 21 and the winding roller 22 rotate in the same direction. For example, the feed roller 21 and the winding roller 22 both rotate clockwise so that the wire is released from the feed roller 21 and wound onto the winding roller 22.
[0026] Please see Figures 1 to 3 The support platform 15 is located between the feeding wheel 21 and the winding wheel 22. During the rotation of the feeding wheel 21, the wire is released to the support platform 15. The vibration generator 11 drives the vibration head 14 to abut against and break the coating layer of the wire on the support platform 15 so that the amorphous alloy wire can be wound around the winding wheel 22.
[0027] Please see Figures 1 to 3 Understandably, the wire with the coating layer to be removed is wound on the unloading wheel 21. The drive assembly 23 drives the unloading wheel 21 and the winding wheel 22 to rotate synchronously, so that the wire can be continuously released to the support platform 15. After the coating layer of the wire is broken and removed by the vibrating head 14, the exposed amorphous alloy wire can be wound on the winding wheel 22. Through the cyclic rotation of the winding wheel 22, the amorphous alloy wire can be continuously wound onto the winding wheel 22.
[0028] Please see Figures 1 to 3 This application utilizes the difference in elastic modulus and thermal expansion properties between the flexible amorphous alloy wire and the brittle cladding layer through the cooperation of the vibration structure 10 and the winding structure 20. The vibration generator 11 drives the vibration head 14 to perform high-frequency vibration, causing the vibration head 14 to continuously and precisely impact the cladding layer, resulting in its breakage and detachment from the amorphous alloy wire. During this breakage process, the vibration head 14 does not contact the amorphous alloy wire, thus preventing damage. Furthermore, the detachment process eliminates the need for hazardous, highly polluting, and difficult-to-control hydrofluoric acid, improving the safety, reliability, and environmental friendliness of the processing.
[0029] Optionally, the vibration generator 11 can be an ultrasonic transducer. The vibration generator 11 can drive the vibration head 14 to perform ultrasonic vibration. The vibration frequency of the vibration generator 11 is in the range of 15~60KHz, the vibration amplitude of the vibration head 14 is in the range of 0~100μm, and the vibration pressure applied by the vibration head 14 to the coating layer is in the range of 0~4000N.
[0030] Please see Figures 1 to 3 It is understandable that the glass cladding layer and the amorphous alloy wire have different coefficients of thermal expansion and modulus of elasticity. The cladding layer is brittle and has low shear resistance, while the amorphous alloy wire has toughness and high vibration resistance. By adjusting and setting the vibration pressure and amplitude of the vibrating head 14, the high-frequency and low-amplitude vibration of the vibrating head 14 can transmit the vibration pressure precisely to the cladding layer without contacting the surface of the amorphous alloy wire. During vibration, the distance from the lower end face of the vibrating head 14 to the upper surface of the support platform 15 is greater than the outer diameter of the amorphous alloy wire but slightly smaller than the outer diameter of the cladding layer. This allows the vibrating head to break the cladding layer without damaging the amorphous alloy wire. The vibrating head 14 can generate precise and controllable instantaneous shear stress at the interface between the cladding layer and the amorphous alloy wire. This shear stress is sufficient to destroy the adhesion between the cladding layer and the amorphous alloy wire. Furthermore, the glass cladding layer is a brittle material with weak shear resistance, thus enabling the cladding layer to break and be quickly peeled off.
[0031] By flexibly adjusting the vibration frequency of the vibration generator 11, the vibration amplitude and vibration pressure of the vibration head 14, the processing requirements of wires with different diameters and different coating thicknesses can be met. At the same time, it can be ensured that the vibration energy only acts on the coating layer and is not transmitted to the amorphous alloy wire. Under the premise of not damaging the amorphous alloy wire, the rapid peeling of coating layers of different specifications can be achieved. There is no medium involved, no chemical medium, no high temperature, no high pressure, and no cavitation effect or bubbles.
[0032] Please see Figures 1 to 3In some embodiments, the feeding wheel 21, the support platform 15 and the winding wheel 22 are arranged linearly and at intervals in the horizontal direction, and the support platform 15 has an upward-facing support surface 151 for supporting the line.
[0033] Optionally, the unloading roller 21, the support platform 15, and the winding roller 22 are arranged sequentially and linearly in a horizontal direction, allowing the wire to move in a straight line from the unloading roller 21 to the support platform 15, and then the amorphous alloy wire to the winding roller 22, finally winding onto the winding roller 22. When the wire moves linearly on the support surface 151, the influence of gravity on the wire tension is reduced, ensuring the wire remains straight and stable during linear conveying and stripping, avoiding additional stress and twisting, thereby ensuring that the vibrating head 14 can deliver continuous and stable impacts at the same height on the wire.
[0034] Please see Figures 1 to 3 In some embodiments, the support surface 151 is arranged horizontally, and the highest point of the winding wheel 22 and the highest point of the unwinding wheel 21 are both located on the horizontal surface defined by the support surface 151.
[0035] Understandably, the highest point of the unloading roller 21 is where the wire leaves the unloading roller. The portion of the wire to be stripped is bent and wound around the unloading roller 21, while the other portion is arranged in a straight line, extending from the highest point of the unloading roller 21 to the support surface 151. Since the highest point of the unloading roller 21 is located on the plane defined by the support surface 151, the straight portion of the wire is horizontal and has no pre-tension stress, which reduces the influence of gravity on the wire tension and ensures that the wire maintains a near-linear translation between the unloading roller 21 and the support platform 15. After the coating layer is removed, the exposed amorphous alloy wire begins to wrap around the winding roller 22 from the highest point of the winding roller 22. During the winding process, the amorphous alloy wire can also maintain a straight translation, reduce the influence of gravity on the tension of the amorphous alloy wire, and be evenly stressed, allowing it to be neatly arranged on the winding roller 22.
[0036] Please see Figures 1 to 3 It is understandable that the wire can be transported at zero angle throughout the entire stripping working area, allowing the wire to move in a straight line between the unloading wheel 21 and the winding wheel 22. This can minimize the bending stress caused by the angle change when the wire enters and leaves the bearing platform 15, reduce the damage to the amorphous alloy wire caused by external force during the stripping process, and protect the internal structure and magnetic properties of the amorphous alloy wire.
[0037] Please see Figures 1 to 3 In some embodiments, the support surface 151 is arranged in the form of a convex arc surface, and the line is supported at the apex of the convex arc surface. The apex of the convex arc surface, the highest point of the winding wheel 22 and the highest point of the unwinding wheel 21 are all located on the same horizontal plane.
[0038] Optionally, the support surface 151 is designed as a convex arc surface, with the wire supported at its apex. The apex has sufficient flatness to allow the vibrating head 14 to break the coating layer. When the vibrating head 14 impacts downwards, the support surface 151 below the wire provides almost point support, allowing the impact energy to be highly concentrated. This enables the brittle coating layer to be broken instantly at the contact point with less vibration energy, improving peeling efficiency. Furthermore, due to the reduced contact area between the wire and the support surface 151, the amorphous alloy wire located between the vibrating head 14 and the winding wheel 22 has almost no contact with the support surface 151, reducing the impact energy transmitted to other locations and enhancing the protection of the amorphous alloy wire.
[0039] Please see Figures 1 to 3 It is also understandable that, since the support surface 151 is set with a convex arc surface, and the wire is peeled off at the apex of the convex arc surface, as the vibrating head 14 drives the bearing platform 15 to vibrate, the broken coating layer debris can slide down from top to bottom under the dual action of gravity and the vibration of the bearing platform 15. This is conducive to chip removal during the crushing process, avoids the accumulation of shards of coating layer around the wire, avoids damage to the amorphous alloy wire, and improves the reliability of amorphous alloy wire peeling.
[0040] Optionally, before the vibrating head 14 impacts the wire, a focused laser beam or a rapid flow of hot air can be used to momentarily and locally heat the wire. Utilizing the difference in thermal expansion coefficients between the cladding layer and the amorphous alloy wire, the thermal stress generated at their interface reduces the adhesion at the interface.
[0041] Please see Figures 2 to 4 In some embodiments, the vibrating head 14 includes a vibrating rod 141 arranged in a vertical direction and a vibrating block 142 connected to the lower end of the vibrating rod 141. The upper end of the vibrating rod 141 is connected to the output shaft of the vibration generator 11, and the vibrating block 142 is used to abut and break the coating layer.
[0042] The vibrating block 142 has an air passage 143, and the surface of the vibrating block 142 facing the support surface 151 has a cooling hole 144. Multiple cooling holes 144 are arranged at intervals, and each cooling hole 144 is connected to the air passage 143.
[0043] Please see Figures 2 to 4 During the vibration of the vibrating block 142, the air passage 143 can be connected to a cooling gas source, such as low-temperature nitrogen. The temperature range of low-temperature nitrogen can be -100 to 0 degrees Celsius. Of course, high-pressure room-temperature air can also be filled into the air passage 143. There are no restrictions here, and the choice can be made according to the actual situation.
[0044] Please see Figures 2 to 4Low-temperature nitrogen flows out from each cooling hole 144 and blows onto the wire located on the support surface 151. The high-speed nitrogen can quickly cool the wire, and the cooled cladding layer becomes more brittle and more easily broken under vibration. Since the cladding layer and the amorphous alloy wire have different shrinkage rates, the shrinkage rate of the cladding layer is less than that of the amorphous alloy wire, which can reduce the bonding force between the cladding layer and the amorphous alloy wire. At the same time, the high-pressure nitrogen can also press the wire onto the support surface 151, so that the wire maintains a certain lateral stability during vibration. In addition, the high-speed nitrogen can also blow away the debris located on the support surface 151, preventing debris from accumulating and damaging the amorphous alloy wire.
[0045] Please see Figures 2 to 4 Optionally, the surface of the vibrating block 142 facing the support surface 151 is smaller than the area of the support surface 151. For example, the area of the support surface 151 is 5 times the area of the corresponding surface of the vibrating block 142, and the vibrating block 142 is located directly above the center of the support surface 151.
[0046] Please see Figures 5 to 6 In some embodiments, the drive assembly 23 includes two rotating shafts 231 that are rotatably arranged, two worm gears 232, a worm 233 that is rotatably arranged, and a rotary driver 234 for driving the worm 233 to rotate. The two rotating shafts 231 are respectively connected to the feed wheel 21 and the winding wheel 22, and the two worm gears 232 are respectively connected to the two rotating shafts 231 and are both engaged with the worm 233.
[0047] Please see Figures 5 to 6 Optionally, the rotary driver 234 can be a motor, such as a servo motor. The rotary driver 234 drives the worm gear 233 to rotate, which in turn drives the two worm wheels 232 to rotate synchronously. The two worm wheels 232 then drive the two rotating shafts 231 to rotate, thereby achieving synchronous rotation of the unwinding wheel 21 and the winding wheel 22. The worm gear 233 transmission features high precision and high rigidity, ensuring speed matching between the take-up end and the unwinding end.
[0048] Optionally, in the working state, the worm 233 drives the two rotating shafts 231 to rotate synchronously through the two worm wheels 232, so that the two rotating shafts 231 can maintain synchronous rotation.
[0049] Please see Figures 5 to 6 The amorphous alloy wire moves in translation between the unloading wheel 21 and the winding wheel 22. The amorphous alloy wire with the coating is released from the annular groove of the unloading wheel 21 onto the support platform 15. After the coating is removed, the amorphous alloy wire is wound into the annular groove of the winding wheel 22 and moves in a circular motion with the winding wheel 22.
[0050] Please see Figures 5 to 6In some embodiments, the drive assembly 23 further includes a fixed plate 25 and a fixed seat 24 disposed on the fixed plate 25 and having a rotating groove 241. Two fixed seats 24 are arranged at intervals along the axial direction of the worm 233. Two rotating shafts 231 are rotatably connected to the two fixed seats 24 respectively. Two worm wheels 232 are located in the two rotating grooves 241 respectively. The support platform 15 is connected to the fixed plate 25.
[0051] Optionally, the support platform 15 and the fixed seat 24 that carries the worm gear 232 and the rotating shaft 231 are both mounted on the same fixed plate 25, forming a core motion module with high rigidity and high integration, ensuring that the relative positional relationship between the winding structure 20 and the support platform 15 remains unchanged and is not affected by external environmental vibration or long-term operation.
[0052] Please see Figures 5 to 6 In some embodiments, the amorphous alloy wire coating peeling device 100 further includes a position adjustment structure 30. Two position adjustment structures 30 are stacked in the vertical direction. The two position adjustment structures 30 are used to drive the fixing plate 25 to move in a first direction and a second direction, respectively. The first direction is orthogonal to the second direction. The fixing plate 25 is connected to the position adjustment structure 30 located above.
[0053] Please see Figure 1 Optionally, both the first and second directions are horizontal, and the first direction can be represented as X and the second direction can be represented as Y.
[0054] Please see Figures 5 to 6 The position adjustment structure 30 includes two spaced guide rails 33, two sliders 32 respectively set on the two guide rails 33, a slide plate 31 connected to the two sliders 32 at both ends, a drive motor 34 connected to the guide rails 33, and a screw mechanism 35 connected to the drive motor 34 and the slide plate 31 at both ends. The drive motor 34 can drive the slide plate 31 to reciprocate along the length direction of the guide rails 33 through the screw mechanism 35.
[0055] Optionally, the two guide rails 33 of the upper position adjustment structure 30 are connected to the slide plate 31 of the lower position adjustment structure 30, with one guide rail 33 of the position adjustment structure 30 arranged along a first direction and the other guide rail 33 of the position adjustment structure 30 arranged along a second direction. The fixing plate 25 is fixed to the slide plate 31 of the upper position adjustment structure 30. Through the two position adjustment structures 30, the position of the support platform 15 can be adjusted along the X and Y directions in the initial stage, so that the support platform 15 is moved directly below the vibrating head 14 to ensure that the impact force is applied vertically and accurately to the line.
[0056] Please see Figure 1 , Figure 2 and Figure 5In some embodiments, the vibration structure 10 further includes an adjustment plate 17, an adjustment seat 123 connected to the adjustment plate 17, guide posts 121 fixedly arranged in the vertical direction, and guide sleeves 122 slidably connected to the guide posts 121. Multiple guide posts 121 are arranged at intervals, and each guide post 121 is provided with a guide sleeve 122. Each guide sleeve 122 is arranged along the circumference of the adjustment plate 17 and is connected to the adjustment plate 17. The vibration structure 10 also includes a positioning plate 13 arranged at intervals relative to the adjustment plate 17 in the vertical direction. An adjustment driver 16 is disposed on the positioning plate 13. The positioning plate 13 is connected to each guide post 121. The two ends of the adjustment seat 123 are respectively connected to the vibration generator 11 and the adjustment driver 16.
[0057] Please see Figure 1 , Figure 2 and Figure 5 Optionally, the guide sleeve 122 can be a linear bearing, and the adjustment driver 16 can be a cylinder or other mechanism that can output linear motion. The cylinder drives the adjustment seat 123, thereby causing the adjustment plate 17 to move downward under the guidance of multiple guide sleeves 122, which in turn causes the vibration head 14 and the vibration generator 11 to move downward together until the vibration head 14 abuts against the covering layer on the support surface 151. By fixing the position of the adjustment plate 17, the vibration generator 11 drives the vibration head 14 to perform high-frequency vibration.
[0058] Please see Figure 1 , Figure 2 and Figure 5 The cooperation of multiple guide posts 121 and multiple guide sleeves 122 can provide precise linear guidance for the movement of the vibrating head 14. For wires of different diameters, the position of the adjusting plate 17 can be adjusted by a cylinder to give the vibrating head 14 a corresponding initial height position.
[0059] Optionally, the amorphous alloy wire coating peeling device 100 also includes a housing 103, which includes an outer cover 101 and a bellows cover 102 connected to the outer cover 101. The vibration structure 10, the position adjustment structure 30 and the winding structure 20 are all located inside the housing 103.
[0060] Please see Figure 7 The present invention also proposes a peeling method, which is implemented by the above-described peeling device 100 for amorphous alloy wire coating. The specific structure of the peeling device 100 for amorphous alloy wire coating is as described in the above embodiments. Since this peeling method adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0061] The peeling method includes the following steps: S1: Prepare the vibration structure 10 and the winding structure 20, and place the vibration head 14 directly above the support platform 15, and connect the vibration head 14 to the output shaft of the vibration generator 11; S2: The wire to be stripped is wound around the unloading wheel 21, and one end of the wire is laid across the support platform 15 and connected to the winding wheel 22, so that the support platform 15 supports the part of the wire located between the unloading wheel 21 and the winding wheel 22. S3: The vibration generator 11 drives the vibration head 14 to abut against the cladding layer and apply a predetermined value of shear stress to the cladding layer to break and remove the cladding layer and expose the amorphous alloy wire at the corresponding position; S4: The drive assembly 23 drives the unloading wheel 21 and the winding wheel 22 to rotate synchronously, so that the unloading wheel 21 releases the wire to be stripped onto the support table 15 and the exposed amorphous alloy wire is wound around the winding wheel 22.
[0062] In some embodiments, the shear stress is less than the yield strength of the amorphous alloy wire and greater than the adhesion between the cladding layer and the amorphous alloy wire.
[0063] Optionally, the shear stress ranges from 5 to 500 MPa. The parameters can be adjusted so that the shear stress is always lower than the yield strength of the amorphous alloy wire and higher than the adhesion between the coating layer and the amorphous alloy wire. This allows the coating layer to break and peel off along the interface without damaging the amorphous alloy wire.
[0064] After the vibration ends, the vibrating head 14 rises and resets, removes debris with high-pressure air, and takes out the amorphous alloy wire roll from the winding wheel 22. The whole process is short and efficient.
[0065] Please see Figure 7 In this embodiment, the amorphous alloy wire has a diameter of 2μm and a coating thickness of 0.5μm. The wire is located in the part of the feeding wheel 21 and the winding wheel 22, and both ends are placed horizontally on the support surface 151. It can maintain horizontal and continuous translational movement and has no pre-tightening stress.
[0066] Based on the diameter of the amorphous alloy wire, the thickness and material of the cladding layer, the vibration parameters of the equipment control system are set as follows: vibration frequency 20KHz (adjustable within the range of 15-60KHz), vibration amplitude 3μm (adjustable within the range of 0-100μm), and vibration pressure 50N (adjustable within the range of 0-4000N).
[0067] The vertical height of the vibration generator 11 is adjusted by the cylinder, so that the vibration head 14 is lowered and pressed against the upper surface of the coating layer, and a certain pressure is applied. The pressure is consistent with the set vibration pressure (0-4000N), thereby completing the initial positioning.
[0068] Adjust the rotation speed of the two rotating shafts 231, which ranges from 0 to 4000 r / min, to control the conveying speed of the amorphous alloy wire; start the vibration generator 11 and continue to act for a predetermined time according to the set parameters to peel off the coating layer through the shear stress of the interface. When only a small section needs to be peeled off, the predetermined time ranges from 0.3 to 0.8 seconds. Of course, when continuous operation is required, the predetermined time depends on the overall length of the line.
[0069] Dry compressed air at 0.1 MPa is blown along the axial direction of the amorphous alloy wire to remove the glass fragments after stripping; finally, the amorphous alloy wire is taken out from the winding wheel 22.
[0070] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
