Problems solved by technology

[0009] Also, this cable is inserted through a body part, so it is used as a non-recyclable disposable product in order to prevent patient infection
After the cable is separated from the drive unit after use, it needs to be replaced with a new one, but there is an inconvenience that the cable needs to be coupled to the drive unit again

Abstract

Provided is a power transmission system for driving a robot joint. A power transmission system for driving a robot joint according to an exemplary embodiment of the present invention is a system for driving a joint of a robot, comprising: a driving unit including a first driving unit and a second driving unit;; a first force transmission unit including a first sheath having a predetermined length, having flexibility, and being formed into a hollow shape, and a first wire which is inserted into the first sheath and has one end fixed to the joint of the robot and another end connected to the first driving unit; and a second force transmission unit including a second sheath which has a predetermined length, has flexibility, and is formed into a hollow shape, and a second wire which is inserted into the second sheath and has one end fixed to the joint of the robot and another end connected to the second driving unit. When the first driving unit provides, to the first wire side, a force in a first direction, the second unit provides, to the second wire side, a force in a second direction that is opposite to the first direction.

Description

Technical field [0001] The present invention relates to an surgical robot, in more detail, relates to a power transmission system for a robot joint drive. Background technique [0002] Recently, with the development of robots in various fields in the industry, the application of the robot in the field, various drivers are developed. In addition to the actuators directly attached to the robot joint, power is also transmitted through various methods of strip, chain, line, etc. [0003] In this driving method, the easiest way is a method of directly attaching an actuator at the link structure, but has a very heavy point of weight of the actuator itself. [0004] To make up for it, a dual input cable drive method is proposed to fix the actuator on the ground and utilize two cable transmission power. [0005] However, the conventional cable driving method as described above is only driven only in the case where the two motors pull the cable, so in order to transmit the driving force t...
