Embodiment Construction

[0050] Hereinafter, a balance link mechanism according to an exemplary embodiment in the present disclosure will be described in detail with reference to the accompanying drawings.

[0051] The balanced linkage mechanism of the present disclosure can be implemented as a robotic arm. However, the scope of the present disclosure is not limited thereto, and it can be implemented in various ways. A balanced linkage mechanism according to the present disclosure will be described as a robotic arm having a plurality of links connected in series.

[0052] The balance link unit according to the present disclosure has a structure in which a plurality of links and joints are continuously connected. When the balance linkage maintains a specific position in a space, the required gravitational torque needs to be generated by a motor and a reducer installed at each joint. If the position of the balance linkage changes, the gravitational torque produced by its own weight also changes. Ther...

Abstract

A counterbalancing linkage mechanism includes a base link including a first joint; a second link forming a second joint to be rotatably connected to the base link; and a counter balancer having one portion disposed at the second joint and another portion movably disposed at the base link along a length direction of the second link. The counter balancer compensates a gravitational torque generated due to a weight of the second link when the second link rotates on the second joint. A third link is connected to the second link. The counter balancer comprises a counter balancer delivery portion connected to the second link and rotating by the rotation of the second link. A counter balancer driving portion is in contact with the counter balancer delivery portion, linearly moves by the rotation of the counter balancer delivery portion, and compensates the gravitational torque and a load capacity due to interaction with the counter balancer delivery portion.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0021591 filed with the Korean Intellectual Property Office on February 12, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a balance linkage mechanism (counterbalancing linkage mechanism, counterbalancing linkage mechanism) that can cooperate with people. More specifically, the present invention relates to a balance linkage mechanism which minimizes the torque required for driving the balance linkage mechanism and generates additional compensating torque by installing a mechanical compensating device for compensating gravity torque . Background technique [0004] Various robots have been used to improve especially production efficiency. Therefore, cooperation between workers and robots is required. However, because there are many problems such as collis...
