In the last few decades, industrial sectors such as smart manufacturing and aerospace have rapidly developed, contributing to the increase in production of more complex electronic boards based on SMT (Surface Mount Technology). The assembly phases in manufacturing these electronic products require the availability of technological solutions able to deal with many heterogeneous products and components. The small batch production and pre-production are often executed manually or with semi-automated stations. The commercial automated machines currently available offer high performance, but they are highly rigid. Therefore, a great effort is needed to obtain machines and devices with improved reconfigurability and flexibility for minimizing the set-up time and processing the high heterogeneity of components. These high-level objectives can be achieved acting in different ways. Indeed, a work station can be seen as a set of devices able to interact and cooperate to perform a specific task. Therefore, the reconfigurability of a work station can be achieved through reconfigurable and flexible devices and their hardware and software integration and control For this reason, significant efforts should be focused on the conception and development of innovative devices to cope with the continuous downscaling and increasing variety of the products in this growing field. In this context, this paper presents the design and development of a multi-mode hybrid micro-gripper devoted to manipulate and assemble a wide range of micro- and meso-SMT components with different dimensions and proprieties. It exploits two different handling technologies: the vacuum and friction.
在过去几十年中，智能制造和航空航天等工业领域迅速发展，促使基于表面贴装技术（SMT）的更复杂电子电路板产量增加。制造这些电子产品的组装阶段需要能够处理多种异质产品和组件的技术解决方案。小批量生产和试生产通常手动进行或使用半自动工作站。目前可用的商用自动化机器性能很高，但刚性很强。因此，需要付出巨大努力来获得具有更高可重构性和灵活性的机器和设备，以尽量减少设置时间并处理组件的高度异质性。这些高层次目标可以通过不同方式实现。实际上，一个工作站可以看作是一组能够相互作用和协作以执行特定任务的设备。因此，工作站的可重构性可以通过可重构和灵活的设备及其硬件和软件集成与控制来实现。出于这个原因，应将大量精力集中在创新设备的构思和开发上，以应对这一不断发展的领域中产品持续缩小尺寸和增加种类的情况。在此背景下，本文介绍了一种多模式混合微夹爪的设计与开发，该微夹爪致力于操作和组装各种不同尺寸和特性的微型和中微型SMT组件。它利用了两种不同的处理技术：真空和摩擦。
