卡扣式连接被归类为联锁连接，通常用于以快速且经济高效的方式组装两个或多个组件。这一机制简单地基于机械灵活性。因此，这些应用程序涵盖了从汽车工程到手机设计的广泛领域。通过将卡扣机构缩放并转换为微米级，也可以利用其优势来组装复杂的微系统。本文开发了一种基于悬臂梁设计的微卡扣配合，并仅用光学技术进行了研究。利用双光子聚合作为微立体光刻技术制作了微器件，并在全息光钳装置中用光学力分析了机械柔性。对锁定机制进行了理论和实验表征，例如，研究了聚合物相对于设计的柔韧性。可以证明，微部件的组装和拆卸都是可以实现的。这些发现为微型机器人、传感器和机械领域的复杂微系统提供了快速和容易的组装。
Snap-fits are classified as interlocking connections and commonly used to assemble two or more components in a fast and cost efficient way. The mechanism is simply based on mechanical flexibility. Therefore, the applications cover a broad field ranging from automotive engineering to mobile phone design. By scaling and transferring the snap-fit mechanism into micrometer scale, advantages can also be utilized to assemble complex microsystems. In this paper, a microsnap-fit based on a cantilever design is developed and investigated by means of optical techniques only. Two-photon polymerization as micro-stereolithography is utilized to manufacture the microcomponents and the mechanical flexibility is analyzed by optical forces in a holographic optical tweezer setup. The locking mechanism is theoretically and experimentally characterized, e.g, the flexibility of the polymer with regard to the design is studied. It can be demonstrated that assembling as well as disassembling of microcomponents is achievable. These findings provide fast and easy assembling of complex microsystems in the fields of microrobotics, -sensors, and -mechanics.
