June 26, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor YANG, Guk Jin (Yongin, KR), filed on November 23, 2013, was made available online on June 12, 2014.

No assignee for this patent application has been made.

Reporters obtained the following quote from the background information supplied by the inventors: "The present invention relates to a multi-parallel manipulator system, and, more particularly, to a multi-parallel manipulator system capable of controlling two or more movable members in a narrow space.

"A parallel manipulator is an apparatus that is used in precision industry such as semiconductor industry, electronic parts, etc. In general, the parallel manipulator serves to move an object from space A to space B. As shown in FIG. 1, a conventional parallel manipulator 10 is configured to couple an object to a movable member 14 and move the object using a plurality of robot arms 13 and a movable member 14 attached to an end of one of the robot arms 13. A drive unit 12 is coupled respectively to the plurality of robot arms 13. The drive unit 12 includes motor devices to correspond to the robot arms 13, respectively. Each of the motor devices includes a motor and a gear module.

"Because the parallel manipulator 10 includes the plurality of robot arms 13, when a worker want to work in a narrow space using two neighboring parallel manipulators, interference with the robot arms of the two parallel manipulators makes it difficult for the worker to work.

"Although the parallel manipulator has an advantage in that it is stable in structure, it has a problem in that it is difficult to use several parallel manipulators together to work in a narrow space due to the problems as described above.

"One example of technology associated with the present invention is Korean Patent Application No. 10-2011-0054463."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "The present invention is designed to solve the problems of the prior art, and therefore it is an object of the present invention to provide a multi-parallel manipulator system capable of independently applying two or more movable members so as to apply two or more parallel manipulators as if the parallel manipulators are present in the same space.

"One aspect of the present invention provides a multi-parallel manipulator system including a first parallel manipulator composed of two or more first drive modules and first movable members coupled to ends of the first drive modules, a second parallel manipulator composed of three or more second drive modules and second movable members coupled to ends of the second drive modules, and a fixture module serving as a fixture member configured to couple the first drive modules to the second drive modules. Here, the first drive modules and the second drive modules are alternately arranged with each other

"In this case, the numbers of the first drive modules and the second drive modules may be less than or equal to 16, each of the first drive modules may include a first motor device, and a first robot arm having a joint structure in which one end thereof is coupled to the first motor device and the other end thereof is coupled to the first movable member, and each of the second drive modules may include a second motor device, and a second robot arm having a joint structure in which one end thereof is coupled to the second motor device and the other end thereof is coupled to the second movable member.

"Also, the multi-parallel manipulator system may further include a connection member bound between the first movable member and the second movable member.

BRIEF DESCRIPTION OF THE DRAWINGS

"The above and other objects, features and advantages of the present invention will become more apparent to those of ordinary skill in the art by describing in detail exemplary embodiments thereof with reference to the attached drawing, in which:

"FIG. 1 is a perspective view showing a conventional parallel manipulator in the present invention;

"FIG. 2 is a perspective view showing a multi-parallel manipulator according to one exemplary embodiment of the present invention; and

"FIG. 3 is a perspective view showing the multi-parallel manipulator according to one exemplary embodiment of the present invention (with a connection member being coupled thereto)."
