Abstract
In a linear driving mechanism for electronic component mounting apparatus that performs mounting operation for mounting an electronic component on a substrate and linearly drives a transfer beamin 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 beamin the Y direction approximately corresponds to a central position Dof inertial resistance of the object to be driven comprising movable portions such as transfer beam, loading head, and transfer plate. Accordingly, twisting moment applied to the transfer beamdue to inertial force is eliminated in acceleration/deceleration, and loading position accuracy is ensured and a component life can be lengthened.
