Three-degree-of-freedom parallel material vibration sorting platform

Abstract

The invention discloses a three-degree-of-freedom parallel material vibration sorting platform and relates to material vibration sorting machinery. The three-degree-of-freedom parallel material vibration sorting platform consists of a movable platform, a fixed platform, a first kinematic chain, a second kinematic chain, a third kinematic chain and an extension spring. The vibration mechanism consists of two PRU kinematic chains and a PRC kinematic chain, and translation of the platform along the X-axis and Z-axis directions and rotation of the platform along the X-axis direction can be realized. According to the traditional vibration sorting platform, one-dimensional material vibration can be realized only, and multi-dimensional vibration cannot be finished. Therefore, the shape and the size of the sorted materials are greatly limited, so that the product does not have the universality. The material vibration sorting platform has the advantages of high decoupling performance, fast dynamic response, convenience in control, simple structure and the like, can meet the multi-dimensional vibration sorting requirements of different materials and is high in universality.

Description

technical field [0001] The invention relates to the field of parallel mechanisms and automatic assembly, and is particularly suitable for sorting and grabbing functional modules of materials on automatic production lines. The vibration sorting platform cooperates with the material grabbing manipulator and the CCD vision system to realize the sorting and supply of materials that are easy to cross and overlap each other or have no obvious structural features, etc., which are not suitable for automatic feeding by vibrating discs. Background technique [0002] At present, the vast majority of domestic devices that realize automatic feeding are vibrating discs. The purpose of the vibrating plate is to automatically and orderly arrange the disordered workpieces in a neat and accurate manner to the next process through vibration. It requires that the parts to be fed do not intersect in the hopper, and have relatively obvious structural features, and the shape of the vibrating pla...
