Problems solved by technology

The upper platform (mobile platform) and the lower platform (frame) of the above-mentioned parallel robot are usually connected by six branches, each branch is provided with a driver to change the length of each branch, so that the position and posture of the upper platform can be changed. Complex structure, high manufacturing cost, and difficult to control
In the automated production lines of light industry, food and electronics industries, operations such as sorting, packaging, and packaging require manipulators with end effectors that can perform high-speed operations in a plane. It is unnecessary, or the manufacturing cost is too high

Embodiment Construction

[0014] The parallel robot of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] see figure 1 , the parallel robot 100 according to the embodiment of the present invention includes a frame 10 , a mobile platform 20 , two connecting branch structures 30 a, 30 b connected between the frame 10 and the mobile platform 20 , and a rotating branch structure 40 . The output end (not shown) of the rotating branch structure 40 is rotatably mounted on the mobile platform 20 , and end effectors such as clamps and suction cups can be mounted on the output end to perform corresponding tasks. The coordinated movement of the two connecting branch structures 30a and 30b can drive the mobile platform 20 to translate in a preset plane, and the rotating branch structure 40 can drive the end effector to rotate, so that the end effector can move in three degrees of freedom.

Abstract

A parallel robot comprises a frame, a movable platform and two connection branch structures, wherein, the two connection branch structures are connected between the frame and the movable platform and can move in the same plane. Each connection branch structure comprises a parallel motion mechanism and a parallelogram rod group, wherein, the parallel motion mechanism is connected with the frame, and the parallelogram rod group is driven by the parallel motion mechanism. The parallelogram rod group comprises a first connecting rod and a second connecting rod which are arranged in parallel, and the first connecting rod and the second connecting rod are articulated with the parallel motion mechanism and the movable platform. The parallel robot has the advantages of simple structure and lower cost, and is convenient to control.

Description

technical field [0001] The invention relates to a parallel robot. Background technique [0002] Most of the existing parallel robots adopt a symmetrical structure with three to six degrees of freedom, and generally use spherical joints, Hookee hinges or moving pairs as kinematic pairs to realize spatial motion with three to six degrees of freedom. The upper platform (mobile platform) and the lower platform (frame) of the above-mentioned parallel robot are usually connected by six branches, each branch is provided with a driver to change the length of each branch, so that the position and posture of the upper platform can be changed. The structure is complex, the manufacturing cost is high, and it is difficult to control. In the automated production lines of light industry, food and electronics industries, operations such as sorting, packaging, and packaging require manipulators with end effectors that can perform high-speed operations in a plane. Then it seems unnecessary,...
