Four-axis swing-arm articulated robot

Abstract

The invention relates to a robot applied to industrial manufacture and the related technical fields, in particular to a four-axis swing-arm articulated robot. The four-axis swing-arm articulated robot comprises a serial machine structure composed of a base component, a biaxial component, a triaxial component and a four-axis component used for picking and placing workpieces, the biaxial component is fixed on the base component vertically, the base component drives the biaxial component to rotate axially, the triaxial component is arranged horizontally with one end slidably connected to the biaxial component, the triaxial component can move on the biaxial component vertically, the four-axis component is arranged horizontally as well with one end rotationally connected to one end, away from the biaxial component, of the triaxial component, and the position, around the joint of the four-axis component and the triaxial component, of the four-axis component is in axial horizontal rotation. By the four-axis swing-arm articulated robot, the problems that conventional four-axis robots are low in safety factor during working, communication lines between axes are damaged easily and the robots cannot work normally in narrow working places and are unsuitable for popularization during production operation on assembly lines for low-price products due to high cost are solved.

Description

Technical field [0001] The invention relates to an industrial robot, in particular to a robot applied in industrial production and manufacturing and related technical fields, that is, a four-axis swing arm joint robot. Background technique [0002] The four-axis robots on the market have the advantages of simple structure, stable operation and high efficiency. They are widely used in various industries. The end of the robot must realize vertical movement up and down and horizontal rotation, so that the end fingers can realize the function of assembly and light handling. In the prior art, this key function relies on the use of a composite screw and hollow reducer. The technical disadvantages of the combination of a composite screw rod and a hollow motor are high cost, complex technology, and long processing time. When it needs to be applied to the production line of some low-priced products, if a six-axis swing arm joint robot or a general four-axis robot is used, the cost is too...
