Domestic research and development NdFeB automatic quality inspection equipment will be more than 300 pieces / minute
Recently, in the mobile phone parts industry, Beijing State Bond Instrument Company, which has been exerting great force, has another big move. According to the size appearance inspection of the NdFeB parts, after several months of research and development, the company's engineering team constantly updated the working efficiency of testing equipment. Can achieve 300 tests per minute. According to the person in charge of the state, the expansion of this equipment is very adaptable. In addition to the expected improvement in detection efficiency, it can also be widely applied to the inspection of the dimensional appearance of other sheet-like workpieces or small parts. NdFeB materials are rare earth permanent magnet materials in an important category, because of its superior performance and known as the "magnetic king." This material has been widely used in the field of consumer electronics (especially mobile phone parts) and the output has been increasing year by year. And in sharp contrast with this is that the industry's product quality testing is very inefficient. Spray-yield and detection of low efficiency of the contradiction, a serious impediment to the development of the NdFeB industry has become a long-standing NdFeB heart disease manufacturers. NdFeB workpiece is generally flaky, smaller, manual testing difficult. In many NdFeB factory testing workshop, workers everywhere wearing gloves, holding tweezers, facing the dense NdFeB parts, intently watching small pieces of the workpiece for testing. This way is more affected by subjective emotions, difficult to grasp the accuracy of the product manufactured pass rate is difficult to protect. In order to solve this industrial problem, Beijing Ling Bang Instrument Technology Co., Ltd. successfully developed the "NdFeB workpiece size appearance inspection equipment", the machine uses machine vision technology, can quickly detect the size and appearance of NdFeB permanent magnet products defects . The device can detect NdFeB workpiece shape wafer, ring, square, square, runway, fan, etc .; product size detection range: diameter or length and width 2 ~ 20mm, the maximum detection accuracy of up to 10 microns; Can effectively identify the appearance defects of the workpiece, such as cracks, scratches, material residue, hole residue, residual work, knock and so on, can replace the artificial naked eye to judge, and the accuracy is higher. The device is highly scalable and, to a limited extent, suitable for the inspection of the dimensions and appearance of other sheet-like workpieces or similar shaped small parts, including gaskets, nuts, magnetic tiles and the like. During the testing process, the equipment can finish the automatic nesting and automatically sort according to the qualified standards set by the user, and classify the qualified products and the unqualified products. Test data can be automatically stored, the software system will be statistics of each batch of products such as pass rate data, but also automatically generate reports, in order to facilitate the quality of traceability and control. The device uses less wear and tear, low maintenance costs after the insured. Can be linked to "after-sale cloud server", with remote diagnosis, remote software upgrades and other services, with the site engineers, to carry out remote maintenance. Equipment R & D engineers, said, "The current size data and appearance defects determine the standard is based on current project needs set, if the user needs to detect different types of products, or set different acceptance criteria, the device can also be based on Needs to be modified or upgraded to provide users with 'tailored' services. " It is understood that the research and development of this new equipment, Beijing Ling Bang company for the national high-tech enterprises, to provide customized testing equipment and services in the country, before the field of defense in the field of a number of successful research and development experience. Cui Zhongwei, chairman of the mechanical and electrical engineering Ph.D., national senior engineer. According to him, this new type of equipment has poured into the endeavor of many well-known talents in the state. This effectively ensured the successful realization of the previous equipment concept. This equipment will provide the entire NdFeB industry (including the mobile phone component industry) Have a positive impact, the state will further promote it. In another development, after minor changes and upgrades to adjust, the device can also flake-like workpieces and similar small parts size and appearance defects detection, with a strong expansion of adaptability. This modern ceiling fan has LED module which has different color temperature can suit your request. Remote control make sure this ceiling fan can be easily control by the owner. Silent motor make no noise which make sure it be quite when it work. The place will look more modern when it has this modern ceiling fan.
