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.

Apparatus and method for automatically mounting electronic parts

An improved apparatus for automatically mounting electronic components includes a take-out nozzle which is rotated by a nozzle rotating unit based on data on an angular position assumed by each chip-shaped electronic component firmly held on the take-out nozzle, in order to perform a correcting operation so as to allow the electronic component to assume an adequate angular position and, after completion of the correction operation, the respective electronic components are mounted on a printed-circuit board. The apparatus includes a storing unit in which an allowable error range is stored, a comparing unit for determining whether or not the present angular positions assumed by the respective electronic components and recognized by a recognized unit remain within the allowable error range, and a controlling unit for controlling the nozzle rotating unit so as to allow a correcting operation to be repeatedly performed based on results derived from the determination made by the comparing unit, until the respective recognized angular positions remain within the allowable error range.
