摘　　要：微夹持器广泛应用于微装配、生物、医疗等领域。目前复杂武器装备生产中的微小型结构件及系统的夹持和装配还是依靠现场工作人员的经验决定,因此,有必要对微夹持器进行研究。以双晶片微夹持器为例,针对复杂三维微小型结构件及系统,提出了集成微力检测与反馈的组合式微夹持技术并研制了相应的微夹持器;阐述了微力检测与反馈的基本原理,搭建了面向双晶片压电陶瓷微夹持器的基于半导体应变片的微力检测与反馈电路。通过夹持实验实现了微力信号的测量与检测,为夹持、移动和装配过程中的微力测量提供了条件。The microgripper is widely used in microassembly,biology and medical applications.Considering that the gripping and assembling micro structural parts and systems in complex weapon production depends on the experience of staff,it is necessary to discuss the issue in detail.Taking a bimorph piezoelectric ceramic microgripper for instance,aiming at complex 3D micro structure and system,a bimorph piezoelectric ceramic microgripping technology integrating micro-force detecting and feedback was proposed,and corresponding microgripper was developed;the theory of micro-force detecting and feedback was discussed in detail,and the micro-force detecting and feedback circuit based on semiconductor-strain was established.The function was realized by experiments,which provides the conditions for micro-force measurement during the clamping,displacing and assembling process.
