AI Technical Summary

Problems solved by technology

Different from the series mechanism, the robot is a closed-loop structure composed of two or more kinematic branch chains, which has the advantages of compact structure, high rigidity, and large load-carrying capacity, and has become one of the ideal choices for robot and machine tool design. There are still some problems to be solved in the robot, such as the kinematics and structural complexity caused by redundant and passive restraint branch chains.

Abstract

The invention discloses a high-speed high-load parallel robot. The high-speed high-load parallel robot comprises a fixed platform, a first driving unit, a second driving unit, a third driving unit, afirst connecting rod, a second connecting rod, a third connecting rod and a movable platform, wherein the fixed platform, the first driving unit, the second driving unit, the third driving unit, the first connecting rod, the second connecting rod, the third connecting rod and the movable platform form a spatial closed loop structure. According to the embodiment, the high-speed high-load parallel robot is more compact and concise in structure, flexible in control and high in rigidity, and is suitable for the fields of precision operation, production line sorting, processing and the like.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a high-speed and high-load parallel robot. Background technique [0002] With the development of the industrial level, the application requirements of robots and machine tools continue to increase, such as the rapid packaging, sorting and handling of light materials in the plastics industry, electronics industry, pharmaceutical industry and food industry; personalized small-scale plane CNC operation Such as cutting, printing and engraving; metal cutting, material welding and surface spraying in the manufacturing field. [0003] Traditional robots are mostly implemented in series, which has problems such as error accumulation and large mass of moving parts. Different from the series mechanism, the robot is a closed-loop structure composed of two or more kinematic branch chains, which has the advantages of compact structure, high rigidity, and large load-carrying capacity, and has become on...
