Abstract

A component lack at a component arrangement position designated by a mounting program at a component feed part which feeds components to be mounted is detected, whether a spare component for the lacking component to be mounted is present in a spare component feed area (16s) of the component feed part is detected, and the supply of the component to be mounted from the designated component arrangement position in the component feed part is switched to the supply of the spare component from the spare component feed area.

Claims

1. A component mounting method, which includes a component mounting order reorganization process wherein after the spare component is automatically switched in the spare component switch process subsequent to the component lack in a component feed method a mounting order is operated in conformity with a component feed state switched for the spare component, thereby re-generating the mounting program.

2. A component mounting apparatus which takes out a component from a component arrangement position designated by a mounting program of a component feed part on the basis of the mounting program and mounts the component to a mounting position on a printed board,

said apparatus comprising:

a component lack detection means for detecting a lack of the component to be mounted at the component arrangement position of the component feed part designated by the mounting program;

a spare component detection judgment means for detecting whether or not a spare component for the lacking component to be mounted is loaded in a spare component feed area of the component feed part, and judging whether or not the spare component is located within the spare component feed area; and

a spare component switch means for switching supply of the component to be mounted from the designated component arrangement position of the component feed part to supply of the spare component from the spare component feed area when the spare component is judged to be present within the spare component feed area by the spare component detection judgment means.

3. A component mounting apparatus according to claim 2, wherein the spare component feed area of the component feed part judged by the spare component detection judgment means is an area other than a component feed area whereat the component supply is designated in the mounting program designed for mounting the component to the printed board of an optional type, so that the supply of the component to be mounted from the component feed area of the component feed part is switched by the spare component switch means to the supply of the spare component from the spare component feed area when the spare component is judged to be present in the spare component feed area by the spare component detection judgment means.

4. A component mounting apparatus according to claim 2, wherein the spare component feed area of the component feed part judged by the spare component detection judgment means is an area overlapping with a component feed area whereat the component supply is designated in the mounting program designed for mounting the component to the printed board of an optional type, so that the supply of the component to be mounted from the component feed area of the component feed part is switched by the spare component switch means to the supply of the spare component from the spare component feed area when the spare component is judged to be present in the spare component feed area by the spare component detection judgment means.

5. A component mounting apparatus according to claim 2, wherein whether or not the spare component for the lacking component to be mounted is loaded in the spare component feed area of the component feed part is detected by the spare component detection judgment means within a component data which stores beforehand information on types or characteristics and arrangement positions of components arranged in the spare component feed area of the component feed part, thereby judging whether or not the spare component is present in the spare component feed area.

6. A component mounting apparatus according to claim 2, which comprises a spare component designation means for preliminarily designating and registering, prior to the spare component detection judgment, a component arrangement position of the spare component at the component feed part which can replace the component to be mounted if the component feed part lacks the component, while the spare component detection judgment means detects the spare component corresponding to the lacking component to be mounted from spare components at the component feed part designated and registered by the spare component designation means, thereby judging the presence/absence of the spare component corresponding to the lacking component to be mounted.

7. A component mounting apparatus, which includes a component mounting order reorganization means for, after the spare component is automatically switched by the spare component switch means subsequent to the component lack in the component feeding apparatus according to claim 2, operating a mounting order in conformity with a component feed state switched for the spare component, and thereby re-generating the mounting program.
