Electronic parts mounting apparatus and electronic parts mounting method
View Patent ↗It is an objective to provide an electronic parts mounting apparatus and an electronic parts mounting method for making it possible to mount various types of electronic parts having equivalent electric characteristics on a single substrate. Before a mount head 15 starts mounting LED parts 4 on substrates 3 positioned by substrate conveyance paths 12 , the number of LED parts 4 still remaining on a plurality of tape feeders 13 is compared, according to the type of the LED part 4 , with target number of LED parts 4 to be mounted on the substrates 3 . When the number of remaining LED parts 4 of at least one type becomes smaller than the target number of LED parts 4 to be mounted, the mount head 15 is deactivated.
1. An electronic parts mounting method under which a plurality of types of electronic parts are mounted on a single substrate according to a defined combination of characteristics of the plurality of types of electronic parts by an electronic parts mounting apparatus that includes a substrate conveyance path for conveying and positioning a substrate on which the plurality of types of electronic parts are to be mounted; a plurality of parts feeders that feed, according to the type, the plurality of types of electronic parts to be mounted on the substrate; a mount head that picks up the plurality of types of electronic parts fed from the respective parts feeders and mounts the thus-picked-up electronic parts to the substrate positioned by the substrate conveyance paths; a remaining parts number calculation unit that calculates a number of electronic parts still remaining on the plurality of parts feeders for each of the plurality of types of the electronic parts; and a target parts-to-be-mounted number memory unit that stores a target number of electronic parts to be mounted on the substrate for each of the plurality of types of the electronic parts, the method comprising:
comparing for each of the plurality of types of the electronic parts, before the mount head starts mounting the electronic parts on the substrate positioned by the substrate conveyance path, the number of electronic parts still remaining on the plurality of parts feeders calculated by the remaining parts number calculation unit with the target number of electronic parts to be mounted on the substrate stored in the target parts-to-be-mounted number memory unit;
determining whether a number of remaining electronic parts still remaining on the plurality of parts feeders calculated by the remaining parts number calculation unit of at least one type is smaller than the target number of electronic parts to be mounted on the substrate stored in the target parts-to-be-mounted number memory unit;
deactivating the mount head when the number of remaining electronic parts of at least one type is determined to be smaller than the target number of electronic parts to be mounted; and
replacing all of the plurality of types of electronic parts in all the plurality of parts feeders, when the number of remaining electronic parts of at least one type of the plurality of types of electronic parts of the defined combination is smaller than the target number of electronic parts to be mounted.
