1. A component mounter comprising:
- (a) a component feeder carriage;
(b) a mounting head having a plurality of suction nozzles for picking up a plurality of components from said feeder carriage;
(c) image capturing means for taking an image of each component held by said suction nozzles after said plurality of suction nozzles have picked up said plurality of components; and
(d) a recognizer for sequentially recognizing each component using image data obtained by said image capturing means according to a mounting sequence of each component;
wherein a recognized component is individually mounted on a mounting target in turn.

Abstract
A component mounter which includes a component feeder carriage; mounting head having two or more suction nozzles for picking up a component from the feeder carriage; image capturing means for taking an image of each component held by the suction nozzles; and a recognizer for recognizing each component based on image data obtained by the image capturing means according to a mounting sequence of each component. Each component is immediately and individually mounted on a mounting target after recognition. This configuration allows to eliminate wasteful standby time, thus offering efficient component mounting.

8. A component mounting method comprising:
-
(a) picking up a plurality of components from a component feeder carriage by a mounting head having a plurality of suction nozzles;
(b) taking an image of each component held by said suction nozzles, by image capturing means, after said plurality of suction nozzles have picked up said plurality of components;
(c) sequentially recognizing each component by a recognizer using said image taken according to a mounting sequence of each component; and
(d) mounting the recognized component individually on a mounting target in turn. - View Dependent Claims (9, 10, 11, 12, 13, 14)
calculating compensation for correcting positional deviation of said each component; and
correcting positional deviation according to said compensation for correcting positional deviation while moving said mounting head.

11. The component mounting method as defined in claim 8, wherein a position of a next component is recognized during mounting of said recognized component.
-
12. The component mounting method as defined in claim 8 further comprising a next step before said step of recognizing each component:
- detecting a suction error for checking the presence of the component on each of said suction nozzles.
-
13. The component mounting method as defined in claim 12, wherein said step of suction error detection is implemented using the image taken by said image capturing means.
-
14. The component mounting method as defined in claim 12, wherein position recognition and mounting are abandoned for a particular suction nozzle in which a suction error is found in said step of detecting a suction error.
