A flexible packaging station for micro-bulk-forming applications based on a standard carrier

Abstract

Machine material handling is complicated in micromanufacturing since standards are not applied and existing handling systems are not flexible. Usually, machine handling systems are highly dependent of microcomponent properties. If the microcomponent is changed, the handling system is also changed. The aim of this paper is to propose a packaging station based on a standard carrier to provide a product-independent inter-machine handling system. Microcomponents are arranged into standard carriers for unifying transport systems. This packaging station was designed to accomplish micro-bulk-forming requirements, but its modular design and its low microcomponent dependencies permit to easily adapt the station to new applications.

Flexibility in metal forming

“…It opens the possibility to customize products and shift geometrical limits of existing processes by using tool paths which lead to advantageous states of stresses or forming zones. Customization is achievable without mechanical changes but only by changing parameters in the CNC control According to the previous study [167], this property of a manufacturing system is called "reusability". Since the product geometry is determined by the tool´s geometry and the relative movement between tool and workpiece tools can be kept geometrically simpler and do not have to include all geometrical features of the product geometry.…”

Dynamic modeling and control of a novel XY positioning stage for semiconductor packaging

“…Most traditional XY stages equipped with rotational motors and ball screws have disadvantages of reduced accuracy, complex mechanical structure and low reliability, and it can not meet the stringent requirements of precision manufacturing and assembly industry (Hace et al, 2011;Liu et al, 2003). Direct-drive motors have the advantages of low friction and high mechanical stiffness, and thus they have been increasingly used in the high speed precision positioning XY stage (Dejima et al, 2005;Sanchez-Salmeron and Ricolfe-Viala, 2012). Consequently, it is very essential to study on the dynamic modeling and controller design of the direct-drive stage to cope with the increasingly demanding requirements.…”
