This paper deals with the design, fabrication and characterization of a tool changer for micromanipulation cells. This tool changer is part of a manipulation cell including a three linear axes robot and a piezoelectric microgripper. All these parts are designed to perform micromanipulation tasks in confined spaces such as a microfactory or in the chamber of a scanning electron microscope (SEM). The tool changer principle is to fix a pair of tools (i.e. the gripper tips) either on the tips of the microgripper actuator (piezoceramic bulk) or on a tool magazine. The temperature control of a thermal glue enables one to fix or release this pair of tools. Liquefaction and solidification are generated by surface mounted device (SMD) resistances fixed on the surface of the actuator or magazine. Based on this principle, the tool changer can be adapted to other kinds of micromanipulation cells. Hundreds of automatic tool exchanges were performed with a maximum positioning error between two consecutive tool exchanges of 3.2 µm, 2.3 µm and 2.8 µm on the X, Y and Z axes respectively (Z refers to the vertical axis). Finally, temperature measurements achieved under atmospheric pressure and in a vacuum environment and pressure measurements confirm the possibility of using this device in the air as well as in a SEM.

“…Among the micromanipulation tools based on a mechanical contact with the component, we can cited the principles based on the following forces: the vacuum [5,40,41,55], the electrostatic force [20,27,33,43], the capillary force [3,8,32], the adhesion force in general [4,19,22,42,49], the inertial effect [24], or even the force generated during a phase change like in cryogenics [31,34]. However, the manipulation can also be performed without mechanical contact as with magnetic, optical, aerodynamic, or acoustical levitation methods [52].…”

“…Of course, the choice of one handling principle over another depends on many parameters such as cycling time, accessibility to the components (mechanically but also optically), and compatibility with the ambient conditions of manipulation. Additional functionalities were also sometimes integrated as, for instance, a force sensor [11,21,23,30,41].Among the micromanipulation tools based on a mechanical contact with the component, we can cited the principles based on the following forces: the vacuum [5,40,41,55], the electrostatic force [20,27,33,43], the capillary force [3,8,32], the adhesion force in general [4,19,22,42,49], the inertial effect [24], or even the force generated during a phase change like in cryogenics [31,34]. This chapter presents theoretical models of micromanipulation tasks allowing optimizing the strategies to get precise and reliable operations and taking into account adhesion effects.…”

Assembly of optical fibers for the connection of polymer-based waveguide

et al. 2003

View full text Add to dashboard Cite

This paper describes the realisation of polymer-based optical structures and the assembly and packaging strategy to connect optical fibre ribbons to the waveguides. For that a low cost fabrication process using the SU-8™ thick photo-resist is presented. This process consists in the deposition of two photo-structurized resist layers filled up with epoxy glue realising the core waveguide. For the assembly, a new modular vacuum gripper was realised and installed on an automatic pick & place assembly robot to mount precisely and efficiently the optical fibres in the optical structures. First results have shown acceptable optical propagation loss for the complete test structure.
