Electronic part mounting method
First Claim
1. In a method of mounting electronic components implemented in an electronic component mounting apparatus which includes an electronic component mounting means having a plurality of nozzles for attracting by suction and mounting electronic components, an imaging means for shooting an image of the electronic component held by one of the nozzles, and a recognition controlling means for analyzing images recorded by the imaging means to inspect the condition of the electronic component, the improvement of a method of determining the status of a nozzle, comprising the steps of:
- storing brightness data representative of a functional nozzle tip;
determining if a suction error for mounting the electronic components has occurred;
taking an image of a nozzle tip which has experienced a suction error for a specific number of times with the imaging means to provide brightness data;
analyzing the brightness data of the image taken of the nozzle tip by comparing the stored brightness data with the image brightness data; and
judging if the nozzle is a definitive nozzle as a result of the analyzing step.

Abstract
The maintenance of nozzles is carried out efficiently and smoothly by automatically identifying a defective nozzle, hence contributing to the increase of productivity. A method of mounting electronic components implemented in an electronic component mounting apparatus which includes an electronic component mounting means (7) provided with a plurality of nozzles (13) for attracting by suction and mounting electronic components (14), an imaging means (15) for shooting an image of the electronic component (14) held by the nozzle (13), and a recognition controlling means (16) for analyzing the image of the electronic component (14) recorded by the imaging means (15) to inspect the condition of the electronic component (14) being attracted, comprises the steps of taking an image of a tip surface of the nozzle (13) with the imaging means (15) which has repeated a suction error by a specific number of times, analyzing the image with the recognition controlling means (16) to inspect the condition of the tip surface of the nozzle (13), and judging the said nozzle (13) as a defective nozzle.
