Title: The Innovative Contributions of Toshio Tsubota
Introduction
Toshio Tsubota is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of robotics, particularly in the development of balance mechanisms for industrial robots. With a total of 3 patents to his name, Tsubota's work has had a lasting impact on robotic technology.
Latest Patents
Tsubota's latest patents include a balance mechanism of an industrial robot. This invention features a first balance mechanism for a first arm that is swingably mounted to the robot's stand, and a second balance mechanism for a second arm attached to the distal end of the first arm. The first balance mechanism utilizes a flexible coupling device, such as a chain, which connects a coupling element to a spring fixed to the stand. This design allows for movement in the direction of deformation when the first arm is angularly moved. The second balance mechanism includes a counterbalancer positioned opposite the operation side of the second arm, with the center of angular movement serving as a fulcrum. These balance mechanisms can be integrated into robots without significant part exchanges, making them versatile for various installations.
Another of Tsubota's inventions is a balancing mechanism that features a vertical robot arm and a horizontal robot arm pivotally mounted to the vertical arm. Each robot arm is equipped with a link mechanism that includes a lever and a spring, which adjusts in response to the movement of the robot arm. This innovative design ensures that the robot arm remains balanced during operation.
