【摘要】：随着德国“工业4.0”,“中国制造2025”等战略的提出,世界范围内新一轮制造业升级就在眼前。激光加工作为一种先进的制造技术,以其加工应用的广泛性、灵活性、非接触等特点,必将起到越来越重要的作用。因此分析激光加工技术的发展现状,梳理激光加工技术的发展轨迹,研究激光加工技术的发展趋势对我国的激光加工产业以及激光加工设备生产企业具有重要的意义。当前全球已有超过4000万条专利,专利作为技术创新成果的重要载体,包含了众多有价值的信息,在基于特定技术领域大规模专利信息的基础上,专利分析方法在研究相应技术领域的发展现状及趋势时有别的方法无法比拟的优势。本文以激光加工领域专利信息为基础,结合专利分析、社会网络分析以及主路径分析方法提出研究框架,对激光加工领域技术发展趋势进行了研究。首先,基于激光加工领域大量专利,从专利数量发展、主要专利权国家、主要专利权人等角度分析了激光加工技术的发展现状。其次,根据基于技术网络的技术发展趋势研究方法,利用Logistic模型划分技术发展阶段,分阶段构建了激光加工领域技术网络,通过对网络结构变化分析以及技术节点核心性指标的计算,得到了激光加工领域的技术发展趋势和核心技术领域。最后,构建专利引用网络,基于SPLC算法提取出核心专利发展轨迹,利用主路径分析结合相关文献分析了主流研发路线,并深入专利个体,识别出专利发展路径上的核心专利。利用上述研究框架,对整个激光加工技术的发展现状及趋势有了清晰的研究,能够为我国激光加工产业以及相关企业的发展战略,研发策略等的制定提供依据和支撑。
[Abstract]:With the development of Germany's "Industry 4.0" and "made in China 2025" strategy, a new round of manufacturing upgrading in the world is at hand. Laser processing, as an advanced manufacturing technology, will play a more and more important role because of its wide range of applications, flexibility, non-contact and so on. Therefore, it is of great significance to analyze the current situation of laser processing technology, to sort out the development track of laser processing technology, and to study the development trend of laser processing technology for the laser processing industry and laser processing equipment production enterprises in China. At present, there are more than 40 million patents in the world. As an important carrier of technological innovation achievements, patents contain a lot of valuable information, which is based on the large-scale patent information in a specific field of technology. Patent analysis methods have unparalleled advantages over other methods in studying the development status and trend of corresponding technical fields. On the basis of patent information in laser processing field, combining patent analysis, social network analysis and main path analysis method, this paper puts forward a research framework, and studies the development trend of laser processing technology. Firstly, based on a large number of patents in the field of laser processing, the development of laser processing technology is analyzed from the perspectives of the number of patents, the main patent countries and the main patentee. Secondly, according to the research method of technology development trend based on technology network, the Logistic model is used to divide the technology development stage, and the technology network in laser processing field is constructed in stages. Based on the analysis of the network structure change and the calculation of the core index of the technical node, the technical development trend and the core technical field of laser processing are obtained. Finally, the patent citation network is constructed, the core patent development path is extracted based on SPLC algorithm, the mainstream research and development route is analyzed by using the main path analysis combined with the related literature, and the patent individual is deeply explored to identify the core patent in the patent development path. Using the above research framework, the present situation and trend of laser processing technology are clearly studied, which can provide the basis and support for the development strategy, research and development strategy of China's laser processing industry and related enterprises.
