The laser wire stripping device uses a laser beam to strip the insulation layer of the high-voltage wire. It can accurately control the focal position and energy density of the laser beam to achieve precise stripping of the thickness of the insulation layer. The entire processing process does not require contact with the wire, avoiding wire damage caused by mechanical friction or extrusion in traditional wire stripping methods.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] Combination Figure 2 , 3 As shown, this embodiment provides a laser wire stripping device, including: a machine table 1, a laser engraving machine 2, a fixture assembly 3, a Z-axis linear module 4 and a Y-axis linear module 5, wherein the Z-axis linear module 4 is vertically arranged on the table of the machine table 1, the Y-axis linear module 5 is horizontally arranged on the table of the machine table 1 along the Y-axis direction, the laser engraving machine 2 is horizontally arranged at the driving end of the Z-axis linear module 4, and can be vertically lifted and lowered under the drive of the Z-axis linear module 4, and the fixture assembly 3 is horizontally arranged at the driving end of the Y-axis linear module 5, and can be shifted along the Y-axis direction under the drive of the Y-axis linear module 5. In particular, there is a loading station and a wire stripping station above the Y-axis linear module 5, and the laser engraving head 22 of the laser engraving machine 2 is located directly above the wire stripping station; the fixture assembly 3 can be reciprocatedly switched between the loading station and the wire stripping station under the drive of the Y-axis linear module 5. Therefore, when the clamp assembly 3 is located at the loading station, the wire is manually clamped on the clamp assembly 3; after clamping is completed, the Y-axis linear module 5 moves the clamp assembly 3 to the wire stripping station, and then the laser engraving machine 2 laser strips the insulation layer on the outside of the wire. The operation is simple, efficient and fast.

[0035] Specifically, the laser engraving machine 2 includes an optical base 21, a laser engraving head 22, and a distance sensor 23. The optical base 21 is horizontally arranged at the driving end of the Z-axis linear module 4, and the laser engraving head 22 and the distance sensor 23 are respectively fixedly arranged at the ends of the optical base 21. It should be noted here that the laser wire stripping device of this embodiment also includes an industrial computer and a display connected to the industrial computer for communication. The industrial computer is installed with control software, and the control software can set, edit, and program various process parameters, such as wire stripping length, wire stripping thickness, and clamping length of the wire. The control end of the industrial computer is respectively connected to the laser engraving machine 2, the distance sensor 23, the Z-axis linear module 4, the Y-axis linear module 5, and the X-axis linear module 35, the servo motor 371, and the tension cylinder 363 to be described below. The control software can control the displacement of each linear module and the laser energy emitted by the laser engraving machine 2 according to the set process parameters and the height measured by the distance sensor 23, and control the servo motor 371 and the tensioning cylinder 363 to complete the automatic laser wire stripping of the device. First, the control software will control the displacement of each linear module to a suitable position according to the set process parameters. Specifically, the Y-axis linear module 5 drives the clamp assembly 3 to move to the loading station to facilitate manual threading and loading; after the wire is clamped, the Y-axis linear module 5 drives the clamp assembly 3 to shift to the bottom of the distance sensor 23, and the height of the wire clamped by the clamp assembly 3 is measured by the distance sensor 23. Furthermore, the control software will control the position of the Z-axis linear module 4 in the Z-axis direction according to the height measured by the distance sensor 23 to achieve a suitable focal length and ensure the accuracy of the laser wire stripping process. Finally, the control software controls the laser energy emitted by the laser engraving machine 2 according to the set wire stripping thickness, so that the laser wire stripping device of this embodiment can achieve multi-step wire stripping and ensure that the roundness of the wire after stripping is ≤0.3mm.

[0036] Furthermore, since the laser wire stripping device generates a large amount of heat during operation, if the heat is not dissipated and cooled in time, the stability and service life of the laser engraving machine 2 will be affected, and even a malfunction may be caused. The laser wire stripping device of this embodiment is also provided with a water cooler 6 and an air knife assembly 7 connected to the water cooler 6. The air knife assembly 7 is arranged on the fixture assembly 3, which is used to take away the heat generated by the laser engraving head 22 during the laser wire stripping process in time, ensuring that the laser engraving machine 2 can maintain stable performance under long-term and high-efficiency working conditions and extend its service life. In addition, since the laser wire stripping device generates a large amount of smoke and dust during operation, these smoke and dust will not only pollute the production environment, but also cause harm to the health of the operator. The laser wire stripping device of this embodiment is also provided with a smoke purifier 8 and an air suction assembly 9 connected to the smoke purifier 8. The air suction assembly 9 is arranged at the end of the optical bench 31, which can filter and purify the smoke and dust generated by the laser engraving head 22 during the laser wire stripping process.

[0037] Furthermore, combined with Figure 4 , 5 As shown, the clamp assembly 3 includes a first base 31, a chuck assembly 32, a first fixed frame 33 and a second fixed frame 34, the first base 31 is horizontally arranged at the driving end of the Y-axis linear module 5; the first fixed frame 33 and the second fixed frame 34 are respectively arranged on the first base 31 along the Y-axis direction; the chuck assembly 32 has multiple groups, including a first pneumatic chuck 321 and a second pneumatic chuck 322 arranged relatively, wherein the first pneumatic chuck 321 is rotatably arranged on the first fixed frame 33, and the second pneumatic chuck 322 is respectively rotatably arranged on the second fixed frame 34. It should be noted here that the centers of the first pneumatic chuck 321 and the second pneumatic chuck 322 both have a central through hole, so that the wire can pass through the central through hole of the second pneumatic chuck 322, and then the end of the wire is fixed at the first chuck 3211 of the first pneumatic chuck 321. Optionally, the chuck assembly 32 of this embodiment is provided with two groups, which can simultaneously feed and strip two wires, greatly improving the production and processing efficiency of the equipment.

[0038] Specific, combined Figure 6 As shown, the first pneumatic chuck 321 includes a first chuck 3211, a first sleeve 3212 and a first chuck 3213 which are coaxially arranged. A first rotating shaft 3214 is convexly arranged in the central axial direction of the first chuck 3213. The first rotating shaft 3214 is rotatably arranged on the first fixing frame 33. The first sleeve 3212 is fixedly arranged on the first chuck 3213. The first chuck 3211 is axially inserted in the first sleeve 3212. In particular, an ejector pin 3215 is inserted in the central through hole of the first pneumatic chuck 321, so that the clamping length of the wire end can be adjusted as needed.

[0039] The second pneumatic chuck 322 includes a coaxially arranged second chuck 3221, a second sleeve 3222, and a second chuck 3223. The second chuck 3223 is axially protruded with a second shaft 3224, which is rotatably arranged on the second fixed frame 34. The second sleeve 3222 is fixedly arranged on the second chuck 3223, and the first chuck 3221 is axially inserted into the second sleeve 3222. In particular, a wire barrel 39 is coaxially arranged at the wire input end of the second pneumatic chuck 322, and the wire barrel 39 is fixedly arranged on the second fixed frame 34 through a fourth fixed frame 38, so that the wire barrel 39 can keep synchronous movement with the second pneumatic chuck 322. The setting of the wire tube 39 plays a guiding and protective role. After the end of the wire passes through the wire tube 39, it passes through the central through hole of the second pneumatic chuck 322, which not only facilitates the clamping of the wire, but also prevents external force from directly acting on the second pneumatic chuck 322 and affecting the service life of the second pneumatic chuck 322.

[0040] Furthermore, the fixture assembly 3 further includes an X-axis linear module 35, and the second fixing frame 34 is displaceably arranged on the first base 31 through the X-axis linear module 35, so that the position of the second pneumatic chuck 322 can be adjusted relative to the first pneumatic chuck 321. The arrangement of the X-axis linear module 35 in this embodiment enables the width between the first pneumatic chuck 321 and the second pneumatic chuck 322 to be adjusted as needed to meet the needs of different wire stripping lengths, which is convenient for the staff to quickly change the model and improve production efficiency.

[0041] Further, the clamp assembly 3 also includes a tensioning assembly 36, which includes a second base 361, a guide assembly 362 and a tensioning cylinder 363. The second base 361 is horizontally arranged at the driving end of the X-axis linear module 35, the guide assembly 362 is arranged on the second base 361 along the X direction, the second fixed frame 34 is slidably arranged on the guide assembly 362, the tensioning cylinder 363 is arranged on the second base 361, and the output end of the tensioning cylinder 363 is connected to the second fixed frame 34. The setting of the tensioning assembly 36 of this embodiment can straighten the wire fixed between the first pneumatic chuck 321 and the second pneumatic chuck 322, so that the internal structure and the external insulation layer of the wire can better withstand the heat and pressure in the laser wire stripping process, thereby improving the accuracy of the laser wire stripping and ensuring the quality of the laser wire stripping.

[0042] Furthermore, the clamp assembly 3 also includes a rotation drive module 37, which is arranged in parallel on one side of the chuck assembly 32, including a servo motor 371, a spline shaft 372, a sleeve 373, a third fixed frame 374 and a synchronous belt 375, wherein the third fixed frame 374 is arranged on the first base 31 and is located on the side of the second fixed frame 34 away from the first fixed frame 33; one end of the spline shaft 372 is rotatably arranged on the third fixed frame 374, and the other end is rotatably arranged on the first fixed frame 33; the sleeve 373 is slidably sleeved on the spline shaft 372, and the sleeve 373 is rotatably arranged on the second fixed frame 34; the output end of the servo motor 371 is connected to the spline shaft 372 for driving the spline shaft 372 to rotate; the synchronous belt 375 has multiple groups for connecting the spline shaft 372 and the chuck assembly 32, so that the first pneumatic chuck 321 and the second pneumatic chuck 322 of the chuck assembly 32 rotate synchronously. The setting of the rotating drive module 37 in this embodiment can drive the first pneumatic chuck 321 and the second pneumatic chuck 322 of the multiple groups of chuck assemblies 32 to rotate synchronously, so that the laser beam can cut the wire evenly along the circumference, realize continuous wire stripping processing of the wire, and improve the overall stripping accuracy.

[0043] Further, combined with Figure 1As shown, the machine 1 is also provided with a protective cover 10 for protection, and the protective cover 10 is provided with components such as a cylinder door, a display bracket, an observation window, an alarm light and a button. Among them, the cylinder door can be raised and lowered and is arranged near the loading station, which is convenient for manual clamping of the wire. In particular, a feeding port is opened on the side of the protective cover 10, near the loading station, and a feeding bracket 11 is arranged below the feeding port, and the feeding bracket 11 is used to support the wire.

[0045] 1. Manually level the feeding bracket 11 and support the feeding bracket 11 with a gas strut;

[0046] 2. Press the power button and the industrial computer button to connect the smoke purifier 8 to the power supply and gas source, and turn on the computer monitor;

[0047] 3. Open the intelligent control software, input parameters or adjust the product formula that needs to be processed, and each linear module will reach the initial position set by the formula. For example: the Y-axis linear module 5 carries the fixture assembly 3 to the loading station to facilitate manual threading and loading; the X-axis linear module 35 carries the second pneumatic chuck 322 to the corresponding position to meet the clamping length requirements of the wire;

[0048] 4. Manually pass the first wire through the second clamp 3221 of the second pneumatic clamp 322, and then insert the end of the first wire into the first clamp 3211 of the first pneumatic clamp 321.

[0050] 6. The Y-axis linear module 5 drives the fixture assembly 3 to the bottom of the distance measuring sensor 23 to measure the height of the wire. The Z-axis linear module 4 adjusts the position of the laser engraving head 22 in the Z-axis direction according to the measured height to achieve a suitable focal length;

[0051] 7. The Y-axis linear module 5 drives the first wire to the bottom of the laser engraving head 22, starts to emit light, and cooperates with the servo motor 371 to drive the first wire to rotate, and the first wire stripping process is performed; after the first wire stripping is completed, the Y-axis linear module 5 drives the second wire to the bottom of the laser engraving head 22, starts to emit light, and cooperates with the servo motor 371 to drive the second wire to rotate, and the second wire stripping process is performed;

[0052] 8. After the laser engraving is finished, the laser stops, the Y-axis linear module 5 drives the fixture assembly 3 back to the loading station, and at the same time the cylinder door rises, and the tension cylinder 363 is released;
