Latest Patents

Nakao's latest patents include a "Component mounting method and apparatus." This invention involves a component handling tool that is moved linearly up and down on a moving mechanism by feedback control of a linear motor. The system is designed to perform pickup and mounting actions of components efficiently. The linear motor is controlled to effect a downward movement of the component handling tool, bringing it closer to the component or mounting object. Upon detecting changes in control information when contact is made, the control of the linear motor switches to a pressing operation, ensuring the component is held or mounted in a prescribed pressed condition.

Another notable patent is the "System for inspecting an apparatus of a printed circuit board." This system detects the motion of a printed circuit board using an encoder arranged alongside a belt conveyor. The encoder generates a detection signal that activates a timing signal generator unit, which in turn generates an image pickup start timing signal. This signal is fed to a time measuring unit to measure the image storing time corresponding to the image pickup start signal. The image signal generated by a line CCD camera is normalized, and the mounting condition of the printed circuit board is judged using image data, resulting in a simple, convenient, low-cost, and high-precision mechanism.
