摘要:
The present invention is a part mounting device for mounting chip parts on a substrate, comprising a linear motor having a columnar yoke with upper and lower ends thereof pivotably supported on the device, permanent magnets disposed in the vicinity of the columnar yoke and forming with the columnar yoke a magnetic circuit, and a bobbin disposed in the vicinity of the columnar yoke and slidable in the columnar direction of the yoke;a chip part holder fixedly secured to the bobbin and having a vacuum nozzle for picking up and holding chip parts;a mechanism connected to said linear motor for controlling the driving of the linear motor for driving the part holder rapidly for moving chip parts quickly from a first position remote from the position of the substrate on which the chip parts are to be mounted to a third position just before the chip parts are on the substrate and then driving the part holder slowly to move the chip parts from the third position to a second position where the chip parts are on the substrate; anda mechanism connected to the yoke for rotating the yoke in a plane transverse to the columnar direction of the yoke.
