Study Of Key Techniques On Manipulator Of RFID Packaging Machine

Because RFID chips become smaller and wider application, it has more and more demands on RFID packaging machine, especially in accuracy and work efficiency. One of the bottlenecks restricting the accuracy and efficiency is the capability of manipulator of RFID packaging machine, which is used to pick up chips, and then transfer the chip to the carrier tape precisely.This paper presents the way to build virtual prototype of manipulator. And Parameters of bonding head in x and y directions, including displacement, velocity, acceleration, driving force, are calculated by motion simulation and dynamic analysis.The results prove that the linear motor can meet the design requirements and no interference or sudden stop occurs.Based on Huston method of multi-body system theory, this paper presents error modeling of manipulator .Transformation matrix between two adjacent bodies with errors is described. The author summarizes all factors which contribute to error and calculate comprehensive error and systematic error. The results offer to error distribution and error compensation.Finally, the key structures of the manipulator are analyzed in static and modal by finite element method .At end of the paper, an improved structure design is discussed. The research to manipulator is useful to promote the research of RFID packaging machine.
