  • Automatic insertion machine for inserting radial lead electronic components
    Patent number: 4070753
    Abstract: This invention relates to a high speed machine which can automatically insert radial lead electronic components onto the printed circuit board one-by-one. A combination of such machines installed at a work station can automatically insert many components onto one printed circuit board at the same time. In a similar way, the combination of such machines installed at many work stations can be arranged into a conveyorized assembly line which can automatically insert many components onto many printed circuit boards simultaneously. The apparatus and method for producing this result will significantly save labor in manufacturing electronic equipment.
