Description

Technical Field

[0001] This invention relates to the field of laser paint removal technology, and in particular to a laser paint removal fixture and method for enameled wire. Background Technology

[0002] Ultra-fine enameled wire (typically referring to wire diameters below 0.1mm, and even as low as 0.01mm) is widely used in high-precision electronic components such as miniature transformers, precision sensors, VCM voice coil motors, miniature inductors, and medical devices. During the manufacturing process of these components, it is often necessary to remove the insulating enamel layer from both ends of the enameled wire for soldering. Therefore, reliable and non-destructive enamel removal is a critical process.

[0003] The main technical methods for removing the enamel coating from enameled wires are as follows: (1) Mechanical scraping method. This method mainly uses tools such as blades, scrapers, or sandpaper to fix the wire on a simple fixture. The mechanical force of scraping with the blade or polishing with sandpaper is used to forcibly destroy and remove the enamel film on the surface of the enameled wire to achieve the purpose of removing the enamel. However, this method is not suitable for removing the enamel from extremely fine enameled wires. The copper conductor of extremely fine enameled wires is extremely fragile and has very low mechanical strength. Any uneven scraping force can easily cause the conductor to be scratched, cut, or even broken directly.

[0004] (2) Chemical dissolution method. This method requires a container filled with organic solvent. The wire is fixed to a bracket with a clip, and the end of the wire is immersed in the solvent. The insulating varnish is removed by chemically dissolving it. However, this method has the problem of difficulty in controlling the diffusion of the chemical solvent when processing extremely fine enameled wires, which makes it difficult to control the accuracy of varnish removal. During the immersion process, the solvent will spread upward along the enameled wire through capillary action, resulting in a varnish removal area that is much longer than expected, affecting the insulation performance of the coil. In addition, most high-efficiency varnish removal solvents are toxic and volatile, which is unfriendly to operators and the environment, and has poor environmental performance.

[0005] (3) Laser paint removal. Laser paint removal utilizes high-frequency, high-energy-density laser pulses to instantaneously irradiate the paint layer surface. The coating layer can instantly absorb the focused laser energy, causing surface oil, rust, or coatings to evaporate or peel off instantly. This high-speed and efficient cleaning method removes surface deposits or coatings, achieving non-contact, high-precision removal of the enameled wire paint layer. The very short laser pulse, under appropriate parameters, will not damage the metal substrate. The main structure includes a laser, a galvanometer system, a focusing field lens, and a set of fixtures for fixing and positioning the wire. Compared to traditional paint removal methods, laser paint removal is more energy-efficient, environmentally friendly, safe, and efficient, especially in the removal of paint from extremely fine enameled wires.

[0006] Currently, in the field of laser coating removal fixtures, existing technologies mainly address enameled wires with relatively large diameters, which may not be suitable for extremely fine enameled wires. Chinese Patent CN114217382A discloses a fixture for optical fiber rotation and an optical fiber fixing method. This patent uses a clamping structure to fix one end of the optical fiber to be cleaned to a corresponding support, and another clamping structure in the same group to fix the optical fiber to be cleaned to the corresponding support, so that the position on the optical fiber to be cleaned is exactly between the two clamping structures in the same group. The part to be cleaned is then cleaned. After cleaning, a driving structure drives the two clamping structures in the same group and the optical fiber between the two clamping structures to rotate by a set angle, continuing to clean the part to be cleaned until the cleaning of the optical fiber is completed. The driving structure then drives the two clamping structures to rotate back to their initial positions, opens the clamping structures, and removes the cleaned optical fiber from the support. This fixture can conveniently realize the placement and removal of optical fibers, the process of clamping and releasing loose optical fibers is relatively simple, and it can achieve batch cleaning of optical fibers to a certain extent. In terms of wire diameter, a single optical fiber (multimode fiber) typically has a diameter of 50 micrometers or 62.5 micrometers. Therefore, replacing the optical fiber with extremely fine enameled wire should also be applicable, and this patented fixture has many advantages. However, in this patented fixture, the optical fiber in the middle of the clamping structure at both ends of the support is manually straightened before the flip plate is closed. If the force applied during manual pulling is too great, the optical fiber may break or be damaged. If the force is insufficient, the optical fiber in the middle section of the two clamping structures may become wavy, thus affecting the laser processing effect.

[0007] Therefore, there is a need to provide a laser stripping fixture and method for enameled wires, so that extremely fine enameled wires can be elastically and adaptively clamped and tensioned, thereby avoiding damage to the enameled wires by manual pulling or affecting the laser processing effect. Summary of the Invention

[0008] The purpose of this invention is to provide a laser stripping fixture and method for enameled wires, in order to solve the problem that manual pulling during laser processing of ultra-fine enameled wires leads to damage to the enameled wires and poor laser processing results.

[0009] To solve the above-mentioned technical problems, the present invention provides a laser stripping fixture for enameled wire, comprising a support device, a driving device, and at least one fixing device. The fixing device includes a wire clamp transfer structure and two rotating shaft structures. The two rotating shaft structures are arranged at intervals along the axial direction of the enameled wire, and the rotating shaft structures are rotatably mounted on the support device around the axis of the enameled wire. The wire clamp transfer structure includes a base plate, a moving end transfer component, and a fixed end transfer component. The two ends of the base plate are respectively fixed to the two rotating shaft structures. The moving end transfer component and the fixed end transfer component are arranged at intervals along the axial direction of the enameled wire on the base plate. The fixed end transfer component is used to clamp the enameled wire, and the moving end transfer component is used to clamp and pull the enameled wire away from the fixed end transfer component. The position of the enameled wire to be stripped is located between the moving end transfer component and the fixed end transfer component. The driving component is used to drive the rotating shaft structure, the base plate, the moving end transfer component, the fixed end transfer component, and the enameled wire clamped by the moving end transfer component and the fixed end transfer component to rotate.

[0010] Optionally, the mobile end transfer assembly includes a mobile end base, a sliding clamping component, and an elastic pulling component. The mobile end base is disposed on the substrate. The sliding clamping component is slidably disposed on the mobile end base along the axial direction of the enameled wire. The elastic pulling component elastically pulls the sliding clamping component on the mobile end base. The sliding clamping component is used to clamp the enameled wire, and the position of the enameled wire to be de-enameled is located between the sliding clamping component and the fixed end transfer assembly.

[0011] Optionally, the elastic tensioning component includes a spring support, a tension spring, and a spring fixing member. The spring support is fixed on the movable end base, one end of the tension spring is fixed on the spring support, and the other end is fixed on the sliding clamping component through the spring fixing member.

[0012] Optionally, the sliding clamping component includes a sliding pivot, a sliding terminal cover, a moving end magnet, and a sliding clamping base. The sliding clamping base is slidably connected to the moving end base. The sliding pivot is disposed on the sliding clamping base. The sliding terminal cover is rotatably connected to the sliding pivot. The moving end magnet is located on the sliding clamping base and the sliding terminal cover.

[0013] Optionally, the fixed end transfer assembly includes a fixed rotating shaft, a fixed terminal cover, a fixed end magnet, and a fixed clamping base. The fixed clamping base is fixedly connected to the substrate, the fixed rotating shaft is disposed on the fixed clamping base, the fixed terminal cover is rotatably connected to the fixed rotating shaft, and the fixed end magnet is located on the fixed clamping base and the fixed terminal cover.

[0014] Optionally, the wire clamp transfer structure further includes at least one intermediate section transfer component. The intermediate section transfer component is sequentially disposed on the substrate along the axial direction of the enameled wire and is located between the moving end transfer component and the fixed end transfer component. The intermediate section transfer component is used to clamp the enameled wire. The position of the enameled wire to be de-enameled is located between adjacent intermediate section transfer components, between the moving end transfer component and the intermediate section transfer component, and between the fixed end transfer component and the intermediate section transfer component.

[0015] Optionally, the rotating shaft structure includes a connecting shaft, a swing connector, and a pin. The connecting shaft is partially rotatably connected to the support device and partially fixedly connected to the substrate. The swing connector is fixedly connected to the connecting shaft. The pin is disposed on the swing connector, and the swing plane of the swing connector is perpendicular to the axial direction of the enameled wire. The pin is disposed parallel to the axial direction of the enameled wire. The driving assembly is used to drive the pin to swing.

[0016] Optionally, the support device includes a female fixture assembly, a female fixture assembly, and a transmission assembly. The female fixture assembly is used for positioning and clamping the female fixture assembly. The female fixture assembly is rotatably connected to the rotating shaft structure. The drive device is mounted on the female fixture assembly. The transmission assembly is disposed on the female fixture assembly. The input end of the transmission assembly is connected to the output end of the drive device. The output end of the transmission assembly is used to drive the rotating shaft structure to move.

[0017] Optionally, the transmission assembly includes two synchronous moving rods, which are slidably connected to the sub-fixture assembly along an axis perpendicular to the enameled wire. Each synchronous moving rod has at least one groove along a direction perpendicular to the sliding direction of the synchronous moving rod and the axis of the enameled wire. The groove is slidably connected to the rotating shaft structure. The driving device is used to drive the synchronous moving rod to slide.

[0018] The present invention also provides a method for laser decoating of enameled wire using the above-mentioned laser decoating fixture, comprising: loading one end of the enameled wire to be decoated onto a fixed-end transfer assembly; loading the other end of the enameled wire to be decoated onto a movable-end transfer assembly, and pulling the enameled wire away from the fixed-end transfer assembly by the movable-end transfer assembly to tension the enameled wire, and positioning the position of the enameled wire to be decoated between the movable-end transfer assembly and the fixed-end transfer assembly; and removing the enameled wire from the support device from two opposite predetermined directions using a laser. A portion of the enamel coating is removed; the rotating shaft structure, the substrate, the moving end transfer component, and the fixed end transfer component are driven by a drive assembly, and the enameled wire held by the moving end transfer component and the fixed end transfer component rotates 90 degrees; a laser removes the remaining enamel coating on the enameled wire from two opposite predetermined directions facing the support device; the rotating shaft structure, the substrate, the moving end transfer component, and the fixed end transfer component are driven by a drive assembly, and the enameled wire held by the moving end transfer component and the fixed end transfer component rotates 90 degrees in the opposite direction.

[0019] The laser stripping fixture and method for enameled wire provided by this invention have the following beneficial effects: Since the fixing device includes a wire clamp transfer structure and two rotating shaft structures, with the two rotating shaft structures spaced apart along the axial direction of the enameled wire, and each rotating shaft structure is rotatably mounted on the support device about the axis of the enameled wire, the wire clamp transfer structure includes a base plate, a moving end transfer assembly, and a fixed end transfer assembly. Both ends of the base plate are respectively fixed to the two rotating shaft structures. The moving end transfer assembly and the fixed end transfer assembly are spaced apart on the base plate along the axial direction of the enameled wire. Therefore, the fixing device can rotate relative to the support device; that is, the rotating shaft structure, the base plate, the moving end transfer assembly, the fixed end transfer assembly, and the component transferred by the moving end... The enameled wire held by the component and the fixed-end transfer component can rotate relative to the support device. Since the position of the enameled wire to be de-enameled is between the moving-end transfer component and the fixed-end transfer component, effective de-enameling of the enameled wire can be achieved. Since the fixed-end transfer component is used to clamp the enameled wire, and the moving-end transfer component is used to clamp and pull the enameled wire away from the fixed-end transfer component, the moving-end transfer component and the fixed-end transfer component can cooperate to clamp and pull the enameled wire, which can automatically straighten the enameled wire. This can achieve elastic adaptive clamping and tensioning of extremely fine enameled wire, avoiding damage to the enameled wire or affecting the laser processing effect due to manual pulling.

Figure 16 This is a schematic diagram of the wire clamp transfer structure 31 of the laser coating removal fixture for enameled wire in an embodiment of the present invention. This embodiment provides a laser coating removal fixture for enameled wire, including a support device 1, a driving device 2 and at least one fixing device 3. The fixing device 3 includes a wire clamp transfer structure 31 and two rotating shaft structures 32. The two rotating shaft structures 32 are arranged at intervals along the axis of the enameled wire 4, and the rotating shaft structures 32 are rotatable around the axis of the enameled wire 4 and are mounted on the support device 1; The wire clamp transfer structure 31 includes a base plate 311, a moving end transfer component 312, and a fixed end transfer component 313. The two ends of the base plate 311 are respectively fixed on the two rotating shaft structures 32. The moving end transfer component 312 and the fixed end transfer component 313 are spaced apart on the base plate 311 along the axial direction of the enameled wire 4. The fixed end transfer component 313 is used to clamp the enameled wire 4, and the moving end transfer component 312 is used to clamp and pull the enameled wire 4 away from the fixed end transfer component 313. The position of the enameled wire 4 to be de-enameled is between the moving end transfer component 312 and the fixed end transfer component 313. The driving component 21 is used to drive the rotating shaft structure 32, the substrate 311, the moving end transfer component and the fixed end transfer component, and the enameled wire 4 held by the moving end transfer component and the fixed end transfer component to rotate.

[0029] Since the fixing device 3 includes a wire clamp transfer structure 31 and two rotating shaft structures 32, the two rotating shaft structures 32 are arranged at intervals along the axial direction of the enameled wire 4. The rotating shaft structures 32 are rotatably mounted on the support device 1 around the axis of the enameled wire 4. The wire clamp transfer structure 31 includes a base plate 311, a moving end transfer component 312, and a fixed end transfer component 313. The two ends of the base plate 311 are respectively fixed to the two rotating shaft structures 32. The moving end transfer component 312 and the fixed end transfer component 313 are arranged at intervals along the axial direction of the enameled wire 4 on the base plate 311. Therefore, the fixing device 3 can rotate relative to the support device 1. That is, the rotating shaft structure 32, the base plate 311, the moving end transfer component and the fixed end transfer component, and the object being transferred can rotate relative to the support device 1. The enameled wire 4 held by the mobile end transfer component and the fixed end transfer component can rotate relative to the support device 1. Since the position of the enameled wire 4 to be de-enameled is between the mobile end transfer component 312 and the fixed end transfer component 313, effective de-enameling of the enameled wire 4 can be achieved. Since the fixed end transfer component 313 is used to clamp the enameled wire 4, and the mobile end transfer component 312 is used to clamp and pull the enameled wire 4 away from the fixed end transfer component 313, the mobile end transfer component 312 and the fixed end transfer component 313 can cooperate to clamp and pull the enameled wire 4, which can automatically straighten the enameled wire 4 and achieve elastic adaptive clamping and tensioning of the extremely fine enameled wire 4, avoiding damage to the enameled wire 4 by manual pulling or affecting the laser processing effect.

[0030] refer to Figure 10 , Figure 11 , Figure 12 and Figure 13The mobile end transfer assembly 312 includes a mobile end base 3121, a sliding clamping component 3122, and an elastic pulling component 3123. The mobile end base 3121 is disposed on the substrate 311. The sliding clamping component 3122 is slidably disposed on the mobile end base 3121 along the axial direction of the enameled wire 4. The elastic pulling component 3123 elastically pulls the sliding clamping component 3122 on the mobile end base 3121. The sliding clamping component 3122 is used to clamp the enameled wire 4, and the position of the enameled wire 4 to be de-enameled is located between the sliding clamping component 3122 and the fixed end transfer assembly 313. Since the sliding clamping component 3122 is slidably disposed on the moving end base 3121 along the axial direction of the enameled wire 4, and the elastic pulling component 3123 elastically pulls the sliding clamping component 3122 onto the moving end base 3121, the sliding clamping component 3122 is used to clamp the enameled wire 4. Therefore, the sliding clamping component 3122 can slide relative to the moving end base 3121 along the axial direction of the enameled wire 4. The elastic pulling component 3123 can elastically pull the sliding clamping component 3122 onto the moving end base 3121, and the enameled wire 4 can be clamped by the sliding clamping component 3122. Thus, after the enameled wire 4 is clamped by the fixed end transfer component 313, the enameled wire 4 can be clamped by the sliding clamping component 3122 and straightened under the pull of the elastic pulling component 3123, thereby achieving elastic adaptive clamping tension.

[0031] Specifically, one end of the enameled wire 4 can be clamped by the fixed end transfer component 313 first, and then the sliding clamping component 3122 can be slid a distance away from the fixed end transfer component 313 relative to the moving end base 3121. Then, the other end of the enameled wire 4 can be clamped by the sliding clamping component 3122. Then, the sliding clamping component 3122 can be released, so that the sliding clamping component 3122 can slide a distance away from the fixed end transfer component 313 under the action of the elastic pulling component 3123. The sliding clamping component 3122 can be fixed in position relative to the moving end base 3121 under the pull of the elastic pulling component 3123 and one end of the enameled wire 4. In this way, the automatic pulling and tensioning of the enameled wire 4 can be realized, that is, adaptive clamping and tensioning can be achieved.

[0032] Furthermore, the elastic tensioning component 3123 includes a spring support 3123-a, a tension spring 3123-b, and a spring fixing member 3123-c. The spring support 3123-a is fixed on the movable end base 3121. One end of the tension spring 3123-b is fixed on the spring support 3123-a, and the other end is fixed on the sliding clamping component 3122 through the spring fixing member 3123-c.

[0033] Specifically, the mobile end base 3121 has multiple threaded holes for installing the spring support 3123-a, so that the position of the tension spring 3123-b installed on the mobile end base 3121 can be adjusted through the threaded holes.

[0034] The tension spring 3123-b has hooks at both ends, which are threaded through small holes at the top of the spring column and on the spring fixing member 3123-c.

[0035] The spring fixing component 3123-c can be a flat-head screw, which can be used to adjust the hook position at one end of the tension spring 3123-b.

[0036] Preferably, the mobile terminal transfer component 312 further includes a mobile terminal slide rail 3124, which is disposed on the mobile terminal base 3121, and the sliding clamping component 3122 is slidably connected to the slide rail.

The sliding clamping base 3122-e is slidably connected to the moving end base 3121. The sliding shaft 3122-a is disposed on the sliding clamping base 3122-e. The sliding terminal cover plate 3122-b is rotatably connected to the sliding shaft 3122-a. The moving end magnet 3122-d is located on the sliding clamping base 3122-e and the sliding terminal cover plate 3122-b. The moving end magnets 3122-d attract each other, causing the sliding terminal cover plate 3122-b to cover the sliding clamping base 3122-e. The enameled wire 4 is clamped by the sliding clamping base 3122-e and the sliding terminal cover plate 3122-b.

[0039] Preferably, the sliding clamping component 3122 further includes a sliding wire groove insert 3122-f, which is embedded in the sliding clamping base 3122-e and is used to guide and position the enameled wire 4.

[0040] refer to Figure 14 The sliding groove insert 3122-f has a first groove 3122-g along the axial direction of the enameled wire 4.

[0041] Specifically, the first groove 3122-g is inverted trapezoidal.

[0042] The sliding groove insert 3122-f is also provided with a first guide notch 3122-h, which is located at both ends of the first groove 3122-g along the direction of the enameled wire 4. The bottom surface of the first guide notch 3122-h is two intersecting triangular planes that intersect with the first groove 3122-g, and the two triangular planes are symmetrically arranged about the first groove 3122-g. In this way, the enameled wire 4 can be easily inserted into the first groove 3122-g.

[0043] The sliding terminal cover plate 3122-b is provided with a first elastic pad 3122-c, which cooperates with the first wire groove 3122-g to clamp the enameled wire 4.

[0044] refer to Figure 12 The fixed-end transfer assembly 313 includes a fixed rotating shaft 3131, a fixed terminal cover plate 3132, a fixed-end magnet 3135, and a fixed clamping base 3136. The fixed clamping base 3136 is fixedly connected to the substrate 311. The fixed rotating shaft 3131 is disposed on the fixed clamping base 3136. The fixed terminal cover plate 3132 is rotatably connected to the fixed rotating shaft 3131. The fixed-end magnet 3135 is located on the fixed clamping base 3136 and the fixed terminal cover plate 3132. The fixed terminal cover plate 3132 is covered on the fixed clamping base 3136 by mutual attraction between the fixed end magnets 3135, and the enameled wire 4 is clamped by the fixed clamping base 3136 and the fixed terminal cover plate 3132.

[0045] The fixing clamping component also includes a fixing wire groove insert 3137, which is embedded in the fixing clamping base 3136 and is used to guide and position the enameled wire 4.

[0046] The fixed wire groove insert 3137 has a second wire groove.

[0047] Specifically, the second groove is in the shape of an inverted trapezoid.

[0048] The fixing slot insert 3137 is also provided with a second guide notch. The second guide notch is located at both ends of the second slot along the direction of the enameled wire 4. The bottom surface of the second guide notch is two intersecting triangular planes. The triangular planes intersect with the second slot, and the two triangular planes are symmetrically arranged about the second slot. In this way, the enameled wire 4 can be easily inserted into the second slot.

[0049] The fixed terminal cover plate 3132 is provided with a second elastic pad 3134, which cooperates with the second wire groove to clamp the enameled wire 4.

[0050] Preferably, the wire clamp transfer structure 31 further includes at least one intermediate section transfer component 314. The intermediate section transfer component 314 is sequentially arranged on the substrate 311 along the axial direction of the enameled wire 4 and is located between the moving end transfer component 312 and the fixed end transfer component 313. The intermediate section transfer component 314 is used to clamp the enameled wire 4. The position of the enameled wire 4 to be de-enameled is between adjacent intermediate section transfer components 314, between the moving end transfer component 312 and the intermediate section transfer component 314, and between the fixed end transfer component 313 and the intermediate section transfer component 314. The intermediate section transfer component 314 can provide auxiliary support for the tensioned ultra-fine enameled wire 4. When the ultra-fine enameled wire 4 is cut to a preset length after de-enameling, the ultra-fine enameled wire 4 can still maintain a clamped and tensioned state, expanding the function of the laser de-enameling fixture and greatly saving time in the wire processing process.

[0051] The intermediate section transfer assembly 314 includes an intermediate rotating shaft 3141, an intermediate terminal cover plate 3142, an intermediate magnet 3143, and an intermediate terminal base 3144.

The intermediate terminal cover plate 3142 is covered on the intermediate clamping base by the mutual attraction between the intermediate magnets 3143, and the enameled wire 4 is clamped by the intermediate clamping base and the intermediate terminal cover plate 3142.

[0052] The intermediate section transfer assembly 314 also includes a third elastic pad 3145, which is disposed on the intermediate terminal cover plate 3142 and is used to cooperate with the intermediate terminal base 3144 to clamp the enameled wire 4.

[0053] In this embodiment, the sliding clamping base 3122-e is fitted with the sliding rotating shaft 3122-a in a transitional fit, allowing the sliding terminal cover 3122-b to rotate around the sliding rotating shaft 3122-a to open and close; the fixed clamping base 3136 is fitted with the fixed rotating shaft 3131 in a transitional fit, allowing the fixed terminal cover 3132 to rotate around the fixed rotating shaft 3131 to open and close; and the intermediate terminal base 3144 is fitted with the intermediate rotating shaft 3141 in a transitional fit, allowing the intermediate terminal cover 3142 to rotate around the intermediate rotating shaft 3141 to open and close.

[0054] In this embodiment, the moving end magnets 3122-d on the sliding terminal cover 3122-b and the sliding clamping base 3122-e have opposite magnetic properties. When the sliding terminal cover 3122-b is closed, the two opposing magnets attract each other, providing an adsorption force to ensure that the first elastic pad 3122-c firmly clamps the ultra-fine enameled wire 4. The fixed end magnets 3135 on the fixed terminal cover 3132 and the fixed clamping base 3136 have opposite magnetic properties. When the fixed terminal cover 3132 is closed, the two opposing magnets attract each other, providing an adsorption force to ensure that the second elastic pad 3134 firmly clamps the ultra-fine enameled wire 4. The intermediate magnets 3143 on the intermediate terminal cover 3142 and the intermediate terminal base 3144 have opposite magnetic properties. When the intermediate terminal cover 3142 is closed, the two opposing magnets attract each other, providing an adsorption force to ensure that the third elastic pad 3145 firmly clamps the ultra-fine enameled wire 4.

[0055] In this embodiment, the sliding clamping base 3122-e and the sliding wire groove insert 3122-f are in clearance fit and locked by fastening screws. The fixed clamping base 3136 and the fixed wire groove insert 3137 are in clearance fit and locked by fastening screws.

[0056] In this embodiment, the mobile terminal base 3121, the fixed clamping base 3136 and the intermediate terminal base 3144 are all positioned on the substrate 311 by the first pin 315 and fixed on the substrate 311 by the first screw.

[0057] In this embodiment, a first window 317 is provided at the position between the substrate 311 and the adjacent intermediate section transfer assembly 314, the position between the moving end transfer assembly 312 and the intermediate section transfer assembly 314, and the position between the fixed end transfer assembly 313 and the intermediate section transfer assembly 314. The first window 317 facilitates laser processing.

[0058] The substrate 311 is also provided with a second pin 318 for limiting the position between itself and the rotating shaft structure 32, and a second screw for connecting with the rotating shaft structure 32.

[0059] refer to Figure 5 , Figure 6 , Figure 8 and Figure 9The rotating shaft structure 32 includes a connecting shaft 321, a swing connector 322, and a pin 323. The connecting shaft 321 is partially rotatably connected to the support device 1 and partially fixedly connected to the substrate 311. The swing connector 322 is fixedly connected to the connecting shaft 321. The pin 323 is disposed on the swing connector 322, with its swing plane perpendicular to the axial direction of the enameled wire 4 and its arrangement parallel to the axial direction of the enameled wire 4. The driving assembly 21 drives the pin 323 to swing, thereby driving the swing connector 322 to swing, which in turn drives the connecting shaft 321 to rotate, thus driving the substrate 311, the moving end transfer assembly 312, the fixed end transfer assembly 313, and the enameled wire 4 to rotate. The pin 323 and the swing connector 322 are in a transition fit and are locked by a first set screw 324 to prevent the pin 323 from loosening.

[0060] Preferably, the connecting shaft 321 has a first opening groove 3211 along the axial direction of the enameled wire 4 for the enameled wire 4 to pass through.

[0061] Preferably, the connecting shaft 321 includes a rectangular portion 3212 and a cylindrical portion 3213, which are fixedly connected. The rectangular portion 3212 is fixedly connected to the base plate 311, and the cylindrical portion 3213 is rotatably connected to the support device 1. The swing connector 322 is sleeved on the cylindrical portion 3213 and fixedly connected by a second set screw 325. The swing connector 322 and the cylindrical portion 3213 are clearance-fitted.

[0062] Preferably, the first opening groove 3211 penetrates the rectangular portion 3212 and the cylindrical portion 3213.

[0063] Preferably, the two sets of rotating shaft structures 32 are symmetrically arranged.

[0064] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The support device 1 includes a female fixture assembly 11, a female fixture assembly 12, and a transmission assembly 13. The female fixture assembly 11 is used for positioning and clamping the female fixture assembly 12. The female fixture assembly 12 is rotatably connected to the rotating shaft structure 32 (connecting to the rotating shaft 321). The drive device 2 is mounted on the female fixture assembly 11, and the transmission assembly 13 is disposed on the female fixture assembly 12. The input end of the transmission assembly 13 is connected to the output end of the drive device 2, and the output end of the transmission assembly 13 is used to drive the rotating shaft structure 32 to move (the pin 323 swings). Thus, the drive device 2 drives the transmission assembly 13, and the transmission assembly 13 drives the rotating shaft structure 32 to move (the pin 323 swings). The rotating shaft structure 32 rotates relative to the sub-fixture assembly 12, thereby realizing the rotation of the fixing device 3 and the enameled wire 4. Since the mother fixture assembly 11 is used for positioning and clamping the sub-fixture assembly 12, the drive device 2 is mounted on the mother fixture assembly 11, and the transmission assembly 13 is disposed on the sub-fixture assembly 12, the sub-fixture assembly 12 and the transmission assembly 13 can be separated from the mother fixture assembly 11 and the drive device 2, so that the sub-fixture assembly 12 and the transmission assembly 13 can be used as separate fixtures, which facilitates the loading and unloading of the enameled wire 4 and the circulation of the enameled wire 4 in the workshop, thereby improving production efficiency and saving the cost of the mother fixture assembly 11 and the drive device 2.

[0065] The mother fixture assembly 11 includes a mother fixture base plate 111, a front positioning strip 112, a left positioning strip 113, a right positioning strip 114, a plurality of first magnets 115, and a plurality of second magnets 116. The front positioning strip 112 is used to position the sub-fixture assembly 12 along the axial direction of the enameled wire 4. The left positioning strip 113 and the right positioning strip 114 are used to position the sub-fixture assembly 12 in a direction perpendicular to the axial direction of the enameled wire 4. The plurality of first magnets 115 are respectively mounted on the left positioning strip 113 and the right positioning strip 114, and the plurality of second magnets 116 are respectively mounted on the front positioning strip 112. The first magnets 115 and the second magnets 116 are used to attract the sub-fixture assembly 12.

[0066] Preferably, the first magnet 115 and the second magnet 116 are circular magnets.

[0067] Preferably, the female fixture assembly 11 further includes a plurality of positioning beads 117, and the plurality of positioning posts are mounted on the left positioning strip 113 and the right positioning strip 114 to facilitate the sliding of the child fixture assembly 12 relative to the female fixture assembly 11.

[0068] Preferably, the left positioning strip 113 and the right positioning strip 114 are L-shaped, and are installed upside down on the base plate 111 of the female fixture. Positioning beads 117 on the left positioning strip 113 are installed on a plane parallel to the base plate 111, and positioning beads 117 on the right positioning strip 114 are installed on a plane perpendicular to the base plate 111. Thus, a stepped surface is formed on both the left and right positioning strips for guiding and limiting the sub-fixture assembly 12.

[0069] Preferably, the base plate 111 of the mother fixture is provided with a second window 1111 to avoid obstructing the laser from focusing on the extremely fine enameled wire 4 of the daughter fixture during the paint removal operation.

[0070] refer to Figure 5 and Figure 6 The sub-fixture assembly 12 includes a sub-fixture base plate 121 and two sub-fixture upright plates 122. The two sub-fixture upright plates 122 are spaced apart on the sub-fixture base plate 121 along the axial direction of the enameled wire 4. A third window 1211 is provided on the sub-fixture base plate 121. The transmission assembly 13 is installed on the sub-fixture upright plate 122. The rotating shaft structure 32 is rotatably installed on the sub-fixture upright plate 122.

[0071] The sub-fixture assembly 12 further includes a rotating shaft bushing 123 and a cylindrical pin 124. The rotating shaft bushing 123 is mounted on the sub-fixture upright plate 122 along the axial direction of the enameled wire 4. The rotating shaft bushing 123 has a second opening groove 1231. The cylindrical pin 124 is mounted on the sub-fixture upright plate 122 for positioning the rotating shaft bushing 123. The upper part of the sub-fixture upright plate 122 has several sets of equally spaced through circular holes and a third opening groove, which transitionally fit with the rotating shaft bushing 123. At the same time, the cylindrical pin 124 positions the rotating shaft bushing 123, ensuring that the second opening groove 1231 of the rotating shaft bushing 123 is aligned with the direction of the third opening groove on the upper part of the sub-fixture upright plate 122. The rotating shaft bushing 123 and the opening groove on the sub-fixture upright plate 122 have similar shapes, both for the purpose of facilitating the placement of the enameled wire 4 into the wire clamp transfer structure 31.

[0072] The sub-fixture assembly 12 also includes a vertical plate reinforcing strip 125, which is axially arranged along the enameled wire 4 to connect the two sub-fixture vertical plates 122. The vertical plate reinforcing strip 125 is installed at both ends of the terminal fixture vertical plate 122 to enhance the stability of the sub-fixture vertical plate 122. The handles 126 at both ends are fixed to the vertical plate reinforcing strip 125 for easy gripping when manually handling the sub-fixture.

[0073] The sub-jig base plate 121 has a stepped surface on each of its left and right sides, which is used to cooperate with the mother jig assembly 11 to facilitate the sub-jig assembly 12 to be guided and pushed into the mother jig assembly 11 for positioning.

[0074] refer to Figure 15 The transmission assembly 13 includes two synchronous moving rods 131, which are slidably connected to the sub-fixture assembly 12 (sub-fixture upright plate 122) along an axis perpendicular to the enameled wire 4. Each synchronous moving rod 131 has at least one sliding groove 1311 along a direction perpendicular to the sliding direction of the synchronous moving rod 131 and the axis of the enameled wire 4. The sliding groove 1311 is slidably connected to the rotating shaft structure 32 (pin 323). The driving device 2 is used to drive the synchronous moving rod 131 to slide.

[0075] Specifically, the slide groove 1311 corresponds one-to-one with the through circular hole on the upper part of the jig stand plate 122, and the size of the slide groove 1311 is adapted to the pin 323. When the synchronous moving rod 131 moves, it can drive the pin 323 to move up and down along the slide groove 1311, thereby driving the two rotating shaft structures 32 to rotate synchronously.

[0076] Preferably, the transmission assembly 13 further includes a synchronous shift rod connecting plate 132, a guide shaft support 133, a guide shaft 134, and a compression spring 135. The guide shaft support 133 is mounted on the sub-fixture assembly 12 (sub-fixture stand plate 122). The synchronous shift rod connecting plate 132 connects two synchronous shift rods 131. One end of the guide shaft 134 is slidably mounted on the synchronous shift rod connecting plate 132 along the sliding direction of the synchronous shift rod 131, and the other end is fixedly mounted on the guide shaft support 133. The compression spring 135 is sleeved on the guide shaft 134 and located between the guide shaft support 133 and the synchronous shift rod connecting plate 132. When the driving device 2 drives the synchronous shift rod 131 to move, the synchronous shift rod connecting plate 132 drives the compression spring 135 to compress. This can guide the movement of the synchronous shift rod 131 and also facilitate the synchronous shift rod 131 to reset under the action of the compression spring 135.

[0077] The guide shaft 134 is stepped, with a large optical shaft at one end, a small optical shaft in the middle, and an external thread at the other end, which is locked onto the guide shaft support 133, which is fixed to the inside of the sub-jig stand plate 122. The inner diameter of the compression spring 135 is slightly larger than the outer diameter of the small optical shaft in the middle of the guide shaft 134, but smaller than the outer diameter of the large optical shaft. The compression spring 135 is coaxially mounted on the guide shaft 134, with one end in contact with the guide shaft support 133 and the other end in contact with the synchronous shift rod connecting plate 132. When the synchronous shift rod connecting plate 132 is driven, it can move along the small optical shaft in the middle of the guide shaft 134, thereby compressing the compression spring 135.

[0078] The transmission assembly 13 also includes a side limiting block 136, which is mounted on the sub-jig upright plate 122 to prevent the synchronous moving rod 131 from shifting outside the sub-jig upright plate 122.

[0079] Specifically, one side of the sub-jig plate 122 is provided with a horizontal rectangular groove for guiding and limiting the synchronous moving rod 131.

[0080] The driving device 2 includes a driving component 21 and a driving mounting base 22. The driving mounting base 22 is mounted on the female fixture assembly 11 (female fixture base plate 111), and the driving component 21 is mounted on the driving mounting base 22. The driving component 21 is used to drive the rotating shaft structure 32 to rotate.

[0081] Specifically, the drive component 21 is a cylinder.

[0082] refer to Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21 , Figure 17 This is a diagram showing the first state of the wire clamp transfer structure 31 of the laser stripping fixture for enameled wire in an embodiment of the present invention, which loads the enameled wire 4. Figure 18 This is a second state diagram of the wire clamp transfer structure 31 of the laser stripping fixture for enameled wire in an embodiment of the present invention, which loads the enameled wire 4. Figure 19 This is a diagram showing the third state of the wire clamp transfer structure 31 of the laser stripping fixture for enameled wire in this embodiment of the invention, which loads the enameled wire 4. Figure 20 This is a diagram showing the fourth state of the wire clamp transfer structure 31 of the laser stripping fixture for enameled wire in this embodiment of the invention, which loads the enameled wire 4. Figure 21 This is a fifth state diagram of the wire clamp transfer structure 31 of the laser stripping fixture for enameled wire in this embodiment of the invention, which loads the enameled wire 4. In this embodiment, the process of removing the enameled wire using the laser stripping fixture is as follows: Stp1: In the single wire clamp transfer structure 31, all the sliding terminal cover plates 3122-b, fixed terminal cover plates 3132 and intermediate terminal cover plates 3142 are opened, and then a section of the enameled wire 4 is positioned by the second guide notch in the fixed end transfer assembly 313, and the enameled wire 4 is laid flat along the inverted trapezoidal second wire groove.

[0083] Stp2: Fixed terminal cover 3132 on the closed fixed end transfer assembly 313.

[0084] Stp3: Slide the sliding clamping component 3122 relative to the moving end base 3121 towards the fixed end transfer component 313 to the maximum stroke, so that the tension spring 3123-b is held in a stretched state. At the same time, position the enameled wire 4 by the first guide notch 3122-h on the side away from the fixed end transfer component 313 of the sliding wire groove insert 3122-f on the moving end transfer component 312. Lay the enameled wire 4 flat along the inverted trapezoidal first wire groove 3122-g for precise positioning.

[0085] Stp4: Close the sliding terminal cover 3122-b on the moving end transfer assembly 312 and release the sliding clamping component 3122 to allow the tension spring 3123-b to automatically rebound, and the enameled wire 4 elastically and adaptively straightens and tensions.

[0086] Stp5: Close the intermediate terminal cover 3142 of the intermediate section transfer assembly 314 in sequence. The intermediate section transfer assembly 314 provides auxiliary support for the clamping of the enameled wire 4. At this point, the enameled wire 4 on the single wire clamp transfer structure 31 is loaded.

[0087] Stp6: Repeat steps Stp1 to Stp5 above, placing the remaining enameled wires 4 into the remaining wire clamp transfer structure 31, and keeping the compression spring 135 in its original state. All enameled wires 4 are in the state before rotation, such as... Figure 3 As shown.

[0088] Stp7: Push the entire sub-jib assembly 12 along the guide groove formed by the stepped surfaces of the left positioning bar 113 and the right positioning bar 114 on the mother jig assembly 11 from front to back until it abuts against the reference surface of the front positioning bar 112. At this time, the synchronous moving rod connecting plate 132 is located on the side of the right positioning bar 114.

[0089] Stp8: Start the laser and perform the first laser paint removal operation on each enameled wire 4 from both top and bottom directions at each of the paint removal sections. The length and positioning of each paint removal section are fixed relative to the positioning reference planes of the sub-jig assembly 12.

[0090] Stp9: The drive unit 2 extends to its maximum stroke and remains extended. The drive unit 2 pushes the synchronous shifting rod connecting plate 132 to the left along the guide shaft 134, thereby driving each fixed device 3 to rotate 90 degrees synchronously around the axis of the rotating bushing 123. Figure 4 As shown, at this time, each enameled wire 4 on the sub-jig assembly 12 is in the rotated state, and the compression spring 135 is in the compressed state, maintaining this state unchanged.

[0091] Stp10: Start the laser and perform a second laser paint removal operation on each of the four sections of each enameled wire from both the top and bottom directions.

[0092] Stp11: Activate the laser, such as Figure 16 As shown, each enameled wire 4 is cut at a specific point, including cutting points A, B, and C, until all enameled wires 4 are cut. This process cuts a single enameled wire 4 into four short, extremely fine enameled wire segments 4. The conductors with the enamel removed from the middle two ends are the enameled wires 4 required by the target.

[0093] Stp12: The drive device 2 retracts to its original position and remains in the retracted state. The driving force is withdrawn, and the synchronous moving rod connecting plate 132 moves from left to right under the restoring force of the compression spring 135, thereby driving each fixed device 3 to synchronously rotate 90 degrees in the opposite direction around the axis of the rotating shaft bushing 123, returning to its original state before rotation. Figure 3 As shown.

[0094] Stp13: Grasp the handle 126 of the sub-jig assembly 12 and remove the sub-jig assembly 12 from the mother jig assembly 11 from back to front.

[0095] Stp14: Open all sliding terminal covers 3122-b, fixed terminal covers 3132, and intermediate terminal covers 3142, and remove the enameled wire segment 4 that has undergone the enamel stripping operation. This completes the entire process of using the enamel stripping fixture for the enameled wire 4.

[0096] This embodiment also provides a method for laser coating removal using the laser coating removal fixture for enameled wire described in the above embodiment, including: A section of the enameled wire 4 to be de-enameled is mounted on the fixed end transfer assembly 313; The other end of the enameled wire 4 to be de-coated is loaded onto the mobile end transfer component 312, and the enameled wire 4 is pulled away from the fixed end transfer component 313 by the mobile end transfer component 312 to make the enameled wire 4 taut, and the position of the enameled wire 4 to be de-coated is between the mobile end transfer component 312 and the fixed end transfer component 313. The laser removes a portion of the enamel coating on the enameled wire 4 from two opposite predetermined directions facing the support device 1. The drive assembly 21 drives the rotating shaft structure 32, the substrate 311, the moving end transfer component and the fixed end transfer component, and the enameled wire 4 held by the moving end transfer component and the fixed end transfer component to rotate 90 degrees. The laser removes the remaining enamel on the enameled wire 4 from two opposite predetermined directions facing the support device 1. The drive assembly 21 drives the rotating shaft structure 32, the substrate 311, the moving end transfer component and the fixed end transfer component, and the enameled wire 4 held by the moving end transfer component and the fixed end transfer component to rotate 90 degrees in the opposite direction.

[0097] Specifically, when the laser removes a portion of the enamel on the enameled wire 4 from two opposite predetermined directions facing the support device 1, the laser emission direction is the same as when the laser removes the remaining enamel on the enameled wire 4 from two opposite predetermined directions facing the support device 1. Thus, by removing the enamel once, rotating the enameled wire 4 by 90°, and then performing a second enamel removal, the enamel on the entire outer surface of the enameled wire 4 can be removed.

[0098] Specifically, the other end of the enameled wire 4 to be stripped is loaded onto the moving end transfer assembly 312, and the moving end transfer assembly 312 pulls the enameled wire 4 away from the fixed end transfer assembly 313 to tension the enameled wire 4, including: The sliding clamping component 3122 is slid a certain distance relative to the moving end base 3121 toward the fixed end transfer assembly 313; The other end of the enameled wire 4 is clamped by the sliding clamping component 3122; Release the sliding clamping component 3122, so that the sliding clamping component 3122 slides a distance away from the fixed end transfer assembly 313 under the action of the elastic pulling component 3123, and fixes the position of the sliding clamping component 3122 relative to the moving end base 3121 under the pull of the elastic pulling component 3123 and the enameled wire 4.

[0099] In the above embodiments, the enameled wire 4 is an extremely fine enameled wire (usually referring to a wire diameter of less than 0.1 mm, or even as low as 0.01 mm).
