Abstract:[Purpose/Significance]With the complexity of industry and technology, it needs to integrate multiple technical fields in order to innovate effectively. The research on the trend of technology convergence is helpful to provide the path of industrial innovation, promote technology convergence and identify emerging technologies.[Method/Process]The research uses LDA and social network method and takes joint robot patent as an example to classify topics from patent literature, refine technical keywords, construct the topics co-occurrence matrix between technical keywords, measure and analyze the trend of technology convergence. [Result/Conclusion]The results show that the patent technology convergence of joint robot present a small world, the convergence trend of mechanical body and drive structure, control system and drive structure is not obvious, sensor is the key core technology, the combination of robot and artificial intelligence is an emerging field of industrial technology development.
Keywords:joint robot patent; LDA; technology convergence; industrial technology development
高新技术产业创新过程中累积了大量的专利,专利的急聚增加一方面说明了创新十分积极活跃,技术的进步更新换代十分迅猛;但另一方面,带来竞争的日益激烈和技术构成的复杂化,需要多个细分的技术领域融合和制造而来,例如,关节机器人产业,又称“关节手臂机器人”或者“关节机械手臂”。随着人机共融技术不断深化,关节机器人技术得到了广泛的应用。《国家中长期科学和技术发展规划纲要(2006-2020年)》提出加强我国自主创新能力,为我国企业自主创新提供政策环境支持,国家“十三五”提出“创新驱动发展”,把创新战略上升到了国家级层面。因此,我国有一大批企业、高校、科研院所投入或者转型对关节机器人进行研发创新,如,清华大学、广西大学、国家电网、科沃斯、百度等,产销规模进一步扩大,根据中国电子学会发布的《中国机器人产业发展报告(2017年)》指出,全球机器人市场规模将达到232亿美元,据预测,关节机器人市场规模将达到88亿美元。全球竞争加剧,我国机器人市场潜力巨大,据统计,我国关节机器人销量将要超过6成。创新主体掌握大量的专利技术,这些专利技术融合在一起共同促进企业的技术创新。关节机器人产业作为早期单一的技术到如今多元化知识技术交叉、融合的高新技术产业,产业的技术创新进步需要多种学科知识和技术集成在一起进行创新应用,一个技术领域的发展往往依赖于其他技术领域的技术融合渗透,驱动发展。……
