Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of machine vision positioning and guiding, and particularly relates to a vision-guided laser deburring device for nanocrystalline magnetic isolation sheets and its application. Background Art
[0002] At present, wireless charging technology has been widely used and promoted in electronic devices such as portable terminals, mobile phones, digital video cameras, etc.
[0003] The working principle of wireless charging technology is that after the coil of the charging base is energized, a magnetic field will be generated around it. When the coil in the mobile phone senses the magnetic field, an induced current will be generated to charge the battery. Therefore, how to ensure effective energy transmission during the charging process and reduce energy loss during wireless charging is the primary problem that domestic electronic manufacturers related to wireless charging production have to face currently.
[0004] In response to this problem, the mainstream solution in the domestic market currently is to attach magnetic isolation materials to the backs of the coils at the transmitting end and receiving end of the wireless charger. The nanocrystalline magnetic isolation sheet is a magnetic material mainly composed of nanocrystalline materials, which has high saturation magnetic induction, low loss, and excellent thermal conductivity. It can effectively reduce energy loss during wireless charging and improve charging efficiency. Its functions of concentrating magnetic field, isolating magnetic field, and guiding magnetic field can help customers improve wireless charging efficiency, reduce heat generation, and reduce electromagnetic interference.
[0005] Since the nanocrystalline magnetic isolation sheet needs to be installed in intelligent devices, very strict requirements are imposed on its thickness and precision. In the manufacturing process of the nanocrystalline magnetic isolation sheet, after several processes such as heat treatment, film laminating, magnetic fragmentation, and die cutting, there will be burr-like residues on the edges of the product. If these residues are not accurately removed, it will affect the overall performance after being assembled into the finished intelligent device. Therefore, it is necessary to introduce a vision system to accurately identify the burr positions and guide the laser process to remove the residual burrs.
[0006] Through the above analysis, the problems and defects existing in the prior art are as follows:

[0048] Combined with the above technical solutions and the solved technical problems, the advantages and positive effects of the technical solution to be protected by the present invention are:
[0049] 1. A breakthrough integration of intelligent defect identification and adaptive laser correction
[0050] The present invention takes the lead in modularly coupling an industrial vision recognition system with a high-energy laser deburring process, and constructs an intelligent system capable of real-time and dynamic recognition of burr boundaries based on a four-level processing mechanism of image acquisition, preprocessing, feature extraction, and edge fitting. Compared with the traditional static laser scanning path, this device can generate a minimum energy path and a dynamic compensation trajectory based on the high-resolution feedback of the workpiece's microscopic morphology, realizing precise repair of irregular or inhomogeneous burr areas, and significantly improving the processing flexibility and response accuracy.
[0051] 2. Cooperative construction mechanism of laser process parameters and material response model
[0052] In view of the thermal sensitivity, magnetic permeability change characteristics of the nanocrystalline magnetic isolation sheet and the differences in burr microstructure, the present invention constructs a non-linear mapping model between multi-dimensional laser parameters such as laser wavelength, single-pulse energy, repetition frequency, and scanning speed and burr stripping behavior through large-sample parameter-response curve training. Based on this model, the system can perform real-time adaptive control of the processing process to ensure that no thermal deformation or structural brittle fracture occurs at the material edge during the burr removal process.
[0053] 3. Closed-loop feedback optimization mechanism under multi-module cooperative control
[0054] The central control module integrates the laser execution unit, the image recognition module, and the data analysis module to achieve full-process closed-loop control from burr positioning, laser processing to result evaluation. By comparing the processed image with the preprocessed image, supplemented by edge residue detection and centroid offset algorithms, the processing accuracy is self-corrected for the second time, promoting the system to form a processing decision logic with autonomous optimization ability, and significantly enhancing the versatility and stability of the system in the processing of multi-batch heterogeneous workpieces.
[0055] 4. Integration of multi-stage environmental protection treatment system for particle purification and aerosol collection
[0056] To control the metal vapor, fine particles, and ozone gas generated during the laser deburring process, the present invention designs an integrated negative-pressure dust collection and triple physical / chemical purification device. Combining a HEPA particle filter element, an activated carbon module, and a UV oxidation treatment unit, it can efficiently remove more than 95% of harmful particles, meet industrial emission standards, and embody the specific implementation of the green manufacturing concept in high-energy processing scenarios.
[0057] 5. Synergistic driving effect of production rhythm optimization and product qualification rate improvement
[0058] Through the embedded image recognition and path automatic correction mechanism, this system can shorten the average processing cycle to less than 60% of the traditional process, while reducing the manual adjustment and detection links. Experimental data shows that on typical nanocrystalline magnetic isolation sheet deburring samples, the burr residue rate is less than 2%, and the qualified product rate is increased to more than 98%, effectively reducing the cost waste caused by secondary rework and scrapping, providing support conditions for large-scale precision production.
[0059] 6. Transformation value of the technical solution and filling of industry gaps
[0060] (1) After the implementation of the present invention, it can be widely applied to high-end equipment manufacturing fields such as new energy, electronic packaging, and precision power device manufacturing, and has significant economic and strategic value in improving product qualification rate, reducing labor costs, and meeting green manufacturing requirements. It can form a complete integrated equipment system of visual inspection - laser processing - feedback evaluation, with the ability of mass production and industrial implementation, and the annual output value can reach the tens of millions level.
[0061] (2) At present, there is no integrated intelligent deburring solution based on the "vision guidance + nanocrystalline property recognition + laser adaptive processing + pollutant collaborative purification" four-in-one at home and abroad. Most of the existing devices rely on fixed-path laser scanning and manual burr confirmation methods, and it is difficult to meet the needs of batch heterogeneous workpieces and high-precision edge quality control. The present invention has broken through the technical bottleneck of unifying multiple objectives of automatic recognition, precise processing, and environmental protection treatment, filling the systematic gap in the field of laser post-treatment of precision electromagnetic materials.
