Patent ID: 7200925

Claim:
A component mounting method comprising: providing component mounting stations positioned along a board transfer path, each of said mounting stations including first and second mounting head sections and first and second component supply tables, each of said first mounting head sections having first nozzles, and each of said second mounting head sections having second nozzles; delivering a board to said board transfer path; at one of said component mounting stations, moving a corresponding one of said first mounting head sections in first and second orthogonal directions, rotating said corresponding one of said first mounting head sections such that said first nozzles of said corresponding one of said first mounting head sections rotate, and successively picking up components from a corresponding one of said first component supply tables arranged on one side of said board transfer path, with said first direction being perpendicular to said board transfer path and said second direction extending along said board transfer path; then successively mounting onto said board, positioned in said board transfer path, the components picked up by said first nozzles of said corresponding one of said first mounting head sections; at said one of said component mounting stations, moving a corresponding one of said second mounting head sections in third and fourth orthogonal directions, rotating said corresponding one of said second mounting head sections such that said second nozzles of said corresponding one of said second mounting head sections rotate, and successively picking up components from a corresponding one of said second component supply tables arranged on an opposite side of said board transfer path, with said third direction being parallel to said first direction and said fourth direction being parallel to said second direction; then successively mounting onto said board, positioned in said board transfer path, the components picked up by said second nozzles of said corresponding one of said second mounting head sections, wherein (i) rotating said corresponding one of said first mounting head sections comprises rotating said corresponding one of said first mounting head sections around a horizontal axis, or (ii) rotating said corresponding one of said second mounting head sections comprises rotating said corresponding one of said second mounting head sections around a horizontal axis.
