Akihiro Urakawa has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electronic component mounting apparatus and electronic component mounting method
    Patent number: 7367117
    Abstract: The invention prevents mismounting of an electronic component caused by missetting of a component feeding unit in an apparatus. A recognition process of an electronic component is performed according to component library data stored in a RAM. According to “normal” data as a check condition in the component library data, a recognition processing device checks whether leads indicated by group numbers “1” and “2” exist or not in the electronic component, on command of a CPU. When all the leads are detected, the CPU commands the recognition processing device to calculate an amount of shifting from a proper position based on an image taken by a component recognition camera, and a position and an angle of the electronic component are calculated. Next, the recognition processing device performs an absence check of leads which must not exist in the electronic component.
