Title: Hiroshi Hohrai: Innovator in Work and Parts Mounting Technology
Introduction
Hiroshi Hohrai is a notable inventor based in Kuwana, Japan. He has made significant contributions to the field of work and parts mounting technology, holding a total of 2 patents. His innovative designs have improved efficiency in various manufacturing processes.
Latest Patents
Hohrai's latest patents include a work mounting apparatus and a parts mounting apparatus. The work mounting apparatus features a head drum that rotates in one direction, with work heads arranged on its outer periphery. Each work head includes a suction nozzle that projects toward a circular travel path, allowing for a cycloidal motion during the drum's rotation. This design enables the suction nozzle to pick up work from a feeder and release it at a desired position on a printed board. The movable table's movement along an intersecting line ensures precise placement of the work.
The parts mounting apparatus utilizes suction nozzles mounted on a rotating carrier driven by a motor. As the carrier rotates, parts are picked up at a feed station and transported to a mounting station, where they are affixed to substrates. A microcomputer controls the timing of the nozzles' pneumatic states based on the rotational speed and position of the carrier, enhancing the accuracy of the mounting process.
