Multi-station SCARA industrial robot

Abstract

The invention discloses a multi-station SCARA industrial robot. The industrial robot includes a SCARA robot mechanism and a displacement drive mechanism, and the SCARA robot mechanism comprises a base, a first arm, a first arm drive device, a second arm, a second arm drive device, a ball spline wire rod and a power supply cable; a first motor and a second motor on the first and second arm drive devices are arranged inside the base, the rotation and lifting of the ball spline screw rod are driven by a third motor through a third drive component, and the SCARA robot mechanism can move under thedrive of the displacement drive mechanism. When the multi-station SCARA industrial robot is produced, multiple workstations require sharing only one SCARA robot mechanism, and thus the occupied spaceand the acquisition costs of equipment are reduced. Additionally, in the SCARA robot mechanism, the first and second motors are arranged inside the base, only the third motor is arranged on the secondarm, the weight of the load on the second arm can be reduced, the cost of spare parts is reduced, and the motion accuracy is improved.

Description

technical field [0001] The invention relates to a multi-station SCARA industrial robot. Background technique [0002] The SCARA robot has 3 revolving joints whose axes are parallel to each other for positioning and orientation in the plane. The other joint is the movement joint, which is used to complete the movement of the end piece in a plane perpendicular to the plane. Because of its fast action, high precision, few parts, and high reliability, it is widely used in high-efficiency assembly, welding, sealing, and handling. [0003] During the use of the existing SCARA robot, there are still the following problems: 1. When each moving component is moving, the positioning and repeat positioning accuracy of the SCARA robot will be affected due to the influence of inertia and gravity. The heavier the moving part, the higher the motor and power requirements, and the higher the operating costs. At the same time, the greater the weight, the greater the inertia when it moves, a...

Problems solved by technology

[0003] During the use of existing SCARA robots, there are still the following problems: 1. When the moving components are in motion, the positioning and repeat positioning accuracy of the SCARA robot will be affected due to the influence of inertia and gravity

2. In industrial production, such as assembly production, each station needs to be equipped with a SCARA robot. In this way, for the assembly workshop, the required production space occupies a large area and the purchase cost of equipment is high

3. When the SCARA robot is moving, the cables that provide power to the motors also move accordingly. The wires are easily damaged due to repeated bending, which reduces the reliability of the SCARA robot.
