“企业产品的精度已不能达到客户需求，这次来到展会现场，重点关注国产品牌高精度、智能化的生产设备。”来自广州中型制造企业的负责人张鹏认为，“国内机器人拥有高性能兼高性价比的整体优势，能够帮助更多像我们这样的中小企业实现工业转型升级。”5月22~24日2019中国（华南）国际机器人与自动化展览会期间，一众国内本土企业打卡亮相，展示企业设备智能化的实力，也为更多传统的制造企业能够尽早实现自动化、智能化制造提供方案。

机器人国产化基本实现

近几年，不少国内自主品牌相继“杀出重围”，从内销，到核心技术研发，出口海外，再到产业链的垂直整合，走出了自己的创新之路。

“相比较进口机器人品牌，我们的研发团队在应对国内市场上，能够快速、直观地理解本土企业的痛点，提供更具针对性的解决方案，并做到更加快速的响应。”展览会上，东莞市必地机器人有限公司销售经理张鹏向记者表示，不同于五年前进口机器人占领大部分市场份额，现如今我国工业机器人基本实现国产化，趋势已扭转。

“将核心部分研发出来，就降低了成本。”欢颜自动化设备（上海）有限公司华南区销售总监杨育磊向记者介绍：“对于工业机器人的作用可以用“核心中的核心”来形容的RV精密减速机，欢颜已用自研产品代替了进口，并在17年就开始批量生产使用。”杨育磊还提到：“进口国外RV精密减速机，不仅采购量受限，受到爱答不理的待遇，并且往往要用数倍的价钱才能买到。”据行业人士介绍，一台精密减速器四大国际巨头采购价为3万元~5万元，卖给国内采购量大的客户约7万元，普通客户约12万元，大多内资企业采购精密减速机的成本比国际巨头贵一倍还多。“在实现了RV精密减速机国产化生产后，优势机器人设备还打开了国外市场。”杨育磊表示。

如今，3C制造业、汽车制造业依然是国产机器人的主要市场，“在汽车零部件和3C自动化的终端落地应用上，最难的部分在于如何将上游机器人、中游的工艺设备和下游的系统集成的产业链打通，而我们已在螺丝拧紧等优势领域上做了最终产业链的垂直整合。这对终端用户来说，更能够提高效率并一站式解决别人单一方面不能解决的问题。”本土企业苏州铂电自动化科技有限公司总经理邓毅对记者说。

据行业专家表示，中国有大量的行业应用场景是国外没有的，很多传统行业劳动密集度高，工人劳动强度大、劳动环境恶劣，但是对技术要求却并不低，这是国产机器人发展的突破点，也给我们带来大量的潜在机会。

核心技术仍是软肋

“市场是决定产品的惟一标准，我国核心零部件长期依赖进口局面仍亟待突破。”业内人士指出。

“虽然拥有自主产权的RV精密减速机，但研发设备还是需要进口，用国内设备目前还做不出高精度的RV。”欢颜杨育磊坦言。

“想要有客户对产品的认可，需要有客户认可的零件，郑州领航机器人有限公司相关负责人王坤表示，“由我们自主研发的机器人工具快换装置中的传感器仍需要进口，这主要在于大多数客户对国外品牌稳定性的认可度。”

另一家企业深表认同，就算是由国内的工业机器人企业为国内的工业企业提供解决方案，工业企业也会在常常要求：某某设备一定要用某某厂家的。
