A four-degree-of-freedom high-speed parallel manipulator

Abstract

The invention relates to a robot, provides a four-degree-of-freedom high-speed parallel-connection manipulator which is high in stability and high in sorting precision, and achieves three-dimensional translation and one-dimensional rotating of a space, and aims at solving the technical problems of poor operation stability, low sorting precision and influence on mechanism efficiency of the manipulator in the prior art. The manipulator comprises a static platform, and a dynamic platform which is lifted on the static platform through four lifting arms; the dynamic platform comprises a lead screw of which one end is provided with a performing device; an upper platform, a medium platform and a lower platform are screwed to the corresponding lead screw above the performing device; a vertical guide rod is arranged on the medium platform; two ends of the vertical guide rod glidingly pass through the upper platform and the lower platform; one end of an upper connecting rod is respectively rotatably connected to one opposite side edge of the upper platform; one end of a lower connecting rod is respectively rotatably connected to the side edge of the lower platform at the same side; a horizontal guide rod horizontally outwards extends on the medium platform at the same size; a sliding sleeve is glidingly connected to the horizontal guide rod; the other one of the ends of the upper connecting rod and the lower connecting rod is respectively rotatably connected to the corresponding sliding sleeve; the lower ends of the lifting arms are respectively hinged to the sliding sleeve and the side edge of the medium platform.

Description

technical field [0001] The invention relates to a robot, in particular to a four-degree-of-freedom high-speed parallel manipulator with good stability and high sorting precision, which realizes three-dimensional translation and one-dimensional rotation in space. Background technique [0002] With the rapid development of the automation industry, in industries such as electronics, light industry, food, and medicine, the operating objects are usually characterized by small size and light weight, and it is often necessary to complete pick-and-place operations such as handling and sorting at a high speed . Especially in the production line of the food and pharmaceutical industries, the materials are relatively light and small, and pollution needs to be avoided. In order to improve the degree of automation and ensure product quality, high-speed robots are usually required for handling, sorting and other operations. [0003] Scholars at home and abroad have also done relevant res...
