Abstract

The invention discloses a pseudo-four-degree-of-freedom parallel robot adopting vertical joints. The robot comprises a frame (1), a static platform (2), a rotation driving mechanism and a two-degree-of-freedom parallel mechanism, wherein the two-degree-of-freedom parallel mechanism comprises a parallel driving mechanism, a rotation support seat (5), a first motion branch chain, a second motion branch chain, a mobile platform (10) and a suction nozzle (11); the parallel driving mechanism comprises a first motion branch chain drive (6) and a second motion branch chain drive (8). The first motion branch chain comprises a first driving rod (7), a first driven rod (15) and a second driven rod (14); the second motion branch chain comprises a second driving rod (9), a third driven rod (13) and a fourth driven rod (12). Four-degree-of-freedom motion can be realized through three driving motors, and the manufacturing cost is greatly reduced; due to adoption of the pure parallel mechanism, the working space of the mobile platform is large, and the robot is high in motion speed, easy to control, symmetrically distributed, simple in design and easy to mount and maintain.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a pseudo four-degree-of-freedom parallel robot with vertical joints. Background technique [0002] At present, in the automated production lines of light industry, food, medicine and electronics industries, many operations such as sorting, packaging, packaging, welding, etc. are performed by robots. Among many robots, parallel robots are often used to achieve multi-directional fast movement. Compared with traditional serial robots, parallel robots have the following characteristics: [0003] 1) High movement precision and repeatability; [0004] 2) Fast movement speed and good dynamic response; [0005] 3) Small footprint; [0006] Due to the above characteristics, parallel robots can be widely used. But at the same time, the number of driving motors of traditional robots is equal to the number of robot degrees of freedom. In order to realize the required number of degrees ...
