Electric-component mounting system
First Claim
1. An electric-component mounting system for mounting electric components on a circuit substrate, comprising:
- a component supply device having a component-supply portion from which said electronic components are supplied one after another;
a circuit-substrate support device that supports said circuit substrate;
a component-holding head rotatable about an axis of rotation thereof and arranged to removably hold a suction nozzle having a sucking surface such that said suction nozzle extends in an axial direction of said component-holding head, said suction nozzle holding each one of said electric components supplied from said component-supply portion of said component supply device, and mounting said each one electric component on said circuit substrate supported by said circuit-substrate support device;
a head rotating device operable to rotate said component-holding head;
a relative-movement device operable to move at least one of said component-holding head and said component supply device relative to an other of said component-holding head and said component supply device, in a direction intersecting said axis of rotation of said component-holding head;
an axial-movement device operable to move at least one of said component-holding head and said component supply device in said axial direction toward and away from an other of said component-holding head and said component supply device;
an image-taking device operable to take an image of said sucking surface in said axial direction toward said sucking surface; and
a control device operable to control said head rotating device, said relative-movement device, said axial-movement device and said image-taking device, and wherein said control device includes a relative-position obtaining portion operable to obtain a relative position between said sucking surface and said axis of rotation of said component-holding head;
a relative-movement control portion operable to control said relative-movement device, for effecting a relative movement between said component-holding head and said component supply device on the basis of said relative position obtained by said relative-position obtaining portion, so as to minimize an error of relative positioning between said sucking surface and a predetermined sucking position of said each one electric component positioned at said component-supply portion of said component supply device; and
a component-transfer control portion operable after said relative movement between said component-holding head and said component supply device by said relative-movement device, to control said axial-movement device to move said at least one of said component-holding head and said component supply device toward said other of said component-holding head and said component supply device, for transferring said each one electric component from said component-supply portion of said component supply device to said suction nozzle.

Abstract
A mounting system for an electric component operates by transferring the electric component from a component supply device to a suction nozzle of a component-holding head on a circuit substrate. A relative position between a sucking surface of the suction nozzle and an axis of rotation of the component-holding head is obtained. A component-holding head and the component supply device are moved relative to each other on the basis of the obtained relative position, so as to minimize an error of relative positioning between the sucking surface and a predetermined sucking position of the electric component positioned at the component-supply portion. The head and the component supply device are then moved toward each other, for transferring the electronic components from the component supply device to the suction nozzle.
