SCARA robot

Abstract

The invention discloses an SCARA (Selective Compliance Assembly Robot Arm) robot which comprises a pedestal, a large arm, a small arm, a first speed reducer and a second speed reducer, wherein the first speed reducer is arranged on the pedestal, and the second speed reducer is arranged on the small arm; one end of the large arm is arranged on the output flange surface of the first speed reducer, and the other end of the large arm is arranged on the output flange surface of the second speed reducer; a first wire passing sleeve for communicating an inner cavity of the pedestal with an inner cavity of the large arm is arranged in an axial through hole of the first speed reducer, and is arranged on the large arm; a second wire passing sleeve for communicating an inner cavity of the small arm with the inner cavity of the large arm is arranged in an axial through hole of the second speed reducer, and is arranged on the small arm; a first wire fixing device is arranged above the first wire passing sleeve; a second wire fixing device and a third wire fixing device are respectively arranged below and above the second wire passing sleeve; the first wire fixing device and the second wire fixing device are both arranged on the large arm, and the third wire fixing device is arranged on the small arm; and an air pipe connector is arranged at the top of the small arm. The SCARA robot is safe and attractive, and the running ranges of first and second joints can be effectively enlarged.

Description

technical field [0001] The invention relates to an industrial robot, in particular to a SCARA robot. Background technique [0002] Today, SCARA robots are widely used in fields such as the plastics industry, the automobile industry, the electronics industry, the pharmaceutical industry, and the food industry. Its main function is to pick up parts and assemble them. The SCARA robot has 3 rotary joints whose axes are parallel to each other for positioning and orientation in the plane, in addition, there is a moving joint for completing the motion of the end piece perpendicular to the plane. This robot has compliance in the x, y directions, and has good stiffness in the z-axis direction. This feature is especially suitable for assembly work, such as inserting a round needle into a round hole, so this robot is first used in large quantities for assembly. Printed circuit boards and electronic components; another feature of the robot is its two-bar structure connected in series, ...

AI Technical Summary

Problems solved by technology

At present, most of the SCARA robots on the market use external wiring, that is, the cables and air pipes are all laid on the outer wall of the robot. Swing occurs bending, limited by this, the operating range of the first and second joints is very small
