This system magnetostrictive actuator as driving parts, introduction of flexible hinge displacement amplification mechanism of giant magnetostrictive actuators output amplification, and to decrease the displacement of giant magnetostrictive actuator design requirements and cost to microcontroller as control core, complete the corresponding hardware and software design. In the whole circuit nozzle along the x, y above without direction, along the Z axis movement, so as to increase the production efficiency, this system also has the jet frequency high, apply glue broad and convenient cleaning, etc. Keywords: giant magnetostrictive actuators； Injection system； Displacement amplification mechanism目录第 1 章绪论 11.1 本文的讨论背景 11.2 点胶机 11.2.1 点胶机的介绍 11.2.2 点胶机的分类 21.2.3 常见的问题 5第 2 章新型微量胶液喷射系统 8针头点胶技术 82.2 无接触喷射式点胶技术 8喷射式点胶技术的推出 82.2.2 喷射式点胶技术的优点 8无接触喷射式点胶技术的工艺参数及优化 92.3 系统总体设计 122.3.1 设计思路 122.3.2 结构设计 132.4 本...
