Vorrichtung und Verfahren zur automatischen Bestückung elektronischer Teile

摘要

An apparatus for automatically mounting electronic parts in which chip-like electronic parts supplied from a parts feeding device are mounted at predetermined positions on a printed substrate. For efficiently and accurately carrying out parts mounting operation by detecting the picked-up state of the electronic parts, the lower end position of the electronic part being held by a holding nozzle is identified at a plurality of points by a lower end position detecting section, while the lower end position memory section stores the detected lower end position. A selecting section selects the lowest end position among the lower end positions detected by the lower end position detecting section, and compares the obtained lowest end position data to data stored in the data memory section including lowest end position data for each sort of electronic part, and a judging section judges if the held state of the electronic part is normal or abnormal.
