The invention relates to an elastic abrasive block assembly line. The elastic abrasive block assembly line comprises an automatic assembly line and an automatic air drying press-fixing line. A conveying system of the automatic assembly line conveys abrasive block assemblies to different stations, and different kinds of assembly operation are conducted at the same time. The abrasive block assemblies are grabbed, glued, placed and assembled together by an adsorption mechanical arm of the automatic assembly line, then the abrasive block assemblies are conveyed to a press-fitting system of the automatic air drying press-fixing line through a taking-out mechanical arm of the automatic air drying press-fixing line to be pressed and fixed, the abrasive block assemblies are subjected to air drying through an air drying system of the automatic air drying press-fixing line, and finished abrasive blocks obtained after air drying are pushed out by a pushing device to fall onto a finished product skip car or a belt conveyor. According to the elastic abrasive block assembly line, the labor intensity of workers is effectively relieved, and the carrying frequency is reduced; due to assembly production of products is achieved, overstock of field products to be manufactured is reduced, and a solid foundation is laid for assembly line production; and the three-dimensional mechanical arms are adopted for assisting assembly line production, full automation is achieved, consistency is guaranteed, and the product quality is guaranteed.
