Patent ID: 8079138

Claim:
A mounting apparatus for electronic components, comprising: a transport unit for transporting a printed board in a first direction; a component supply device disposed on an outside in a second direction that is perpendicular to the first direction relative to the transport unit; a first y-beam and a second y-beam that extend in the second direction, the first and second y-beams being spaced apart from each other; a first x-beam and a second x-beam that extend in the first direction so as to bridge between the first y-beam and the second y-beam; a first mounting head disposed on the first x-beam and a second mounting head disposed on the second x-beam, the first mounting head and the second mounting head for mounting electronic components from the component supply device on the printed board; a first encoder disposed on the first y-beam or the second y-beam and the first x-beam, the first encoder for detecting the position of the first mounting head; a second encoder disposed on the first y-beam or the second y-beam and the second x-beam, the second encoder for detecting the position of the second mounting head; wherein the first mounting head moves based on a command inputted to a first servo amplifier from a host computer via a first motion controller; the second mounting head moves based on a command inputted to a second servo amplifier from the host computer via a second motion controller; the position information from the first encoder is fed back to the first servo amplifier and the first motion controller; the position information from the second encoder is fed back to the second servo amplifier and the second motion controller; the first motion controller calculates speed information and acceleration information of the first mounting head based on the position information from the first encoder; the second motion controller calculates speed information and acceleration information of the second mounting head based on the position information from the second encoder; and the first motion controller and the second motion controller share the position information, the speed information, and the acceleration information of the first mounting head and the position information, the speed information, and the acceleration information of the second mounting head.
