Abstract

The invention discloses a Scara robot which comprises a first rotation joint, a second rotation joint, a rotation and movement compound motion joint and a spline lead screw. The first rotation joint is connected with the second rotation joint, the other end of the second rotation joint is connected with the rotation and movement compound motion joint, the rotation and movement compound motion joint comprises a rotation joint and a movement joint, the rotation joint is output through a third servo motor, decelerated through a third harmonic reducer and driven to a ball spline inner ring through a synchronous belt, and a deep groove ball bearing is added in the third harmonic reducer to be used as an auxiliary support. According to the Scara robot, the deep groove ball bearing is added in the third harmonic reducer in the rotation and movement compound motion joint, therefore, the operation rigidity of the robot is effectively improved, the structure is compact, and the accuracy is high.

Description

technical field [0001] The invention relates to a robot capable of grasping in a plane, in particular to a Scara robot. Background technique [0002] In the current industrial field, including the automobile industry, electronic and electrical industry, construction machinery industry, etc., a large number of industrial robot automation production lines have been used. Industrial robots are advanced manufacturing technologies integrating precision, flexibility, intelligence, and software application development. Resource consumption and environmental pollution are the highest manifestations of industrial automation. [0003] The Scara robot belongs to a special type of industrial robot with cylindrical coordinates. It has three rotary joints whose axes are parallel to each other, and is positioned and oriented in a plane. Another articulated movement joint is used to complete the movement of the end piece in a perpendicular plane. This type of robot has a light structure ...
