Example Embodiment

[0023] In order to better understand the present invention, the present invention is further described below with reference to the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0024] like figure 1 As shown, the two-dimensional translation two-degree-of-freedom plane parallel robot mechanism of the present invention includes a static platform 1, a moving platform 2 and a branch chain connecting the static platform 1 and the moving platform 2, and the moving platform 2 is connected to the static platform through four branch chains. The platform 1 is connected, two of which are active branches 3 and 4, and the other two are passive branches 5 and 6; the active branch 3 (4) includes a driving arm 3.1 (4.1) and a driven arm 3.2 (4.2) , one end of the driving arm 3.1 (4.1) is connected with the static platform 1 through the rotating pair, the other end is connected with the driven arm 3.2 (4.2) through the rotating pair, and the ...

Abstract

A two-freedom robot mechanism with 2D translation and planar parallel connection is composed of a static plat form, a dynamic platform, and 4 branches including 2 active branches and 2 passive branches for linking dynamic platform with static platform. Said active branch consists of a drive arm and a driven arm.

Description

technical field [0001] The invention belongs to the field of robot mechanisms, in particular to a two-dimensional translational two-degree-of-freedom plane parallel robot mechanism suitable for pick-and-place operations. Background technique [0002] In the existing robot of robotization operation, there are two types of mechanisms: series mechanism and parallel mechanism. The tandem mechanism has the advantages of large working space and high flexibility. At the same time, it also has some disadvantages: not only the error accumulation of each member, the end precision is low, but also the inertia is large, the stiffness is low, and the dynamic performance is poor. [0003] Parallel mechanism is a closed multi-loop mechanism with multiple degrees of freedom of motion and drives distributed on different loops. Compared with serial robots, parallel robots have a series of advantages such as high rigidity, strong load-carrying capacity, no accumulation of position errors, hig...
