Linear driving mechanism and electronic component mounting apparatus using the same

摘要

In a linear driving mechanism which is arranged in electronic component mounting apparatus that performs mounting operation for mounting an electronic component on a substrate and linearly drives a transfer beam 8 in a Y direction using a linear motor, an object to be driven and the linear motor are disposed such that a position P of thrust generated by the linear motor for driving the transfer beam 8 in the Y direction approximately corresponds to a central position D 1 of inertial resistance of the object to be driven comprising movable portions such as transfer beam 8 , loading head 9 , and transfer plate 12 . Accordingly, twisting moment applied to the transfer beam 8 due to inertial force is eliminated in acceleration/deceleration, and loading position accuracy is ensured and a component life can be lengthened.
