Sintered brick blank grouping method and device

The invention discloses a sintered brick blank grouping method and device. A blank cutting machine, a blank conveying machine, a grouping belt conveyor I, a grouping belt conveyor II and a grouping belt conveyor III are included. The blank conveying machine is adopted to be supported above the grouping belt conveyor I and the grouping belt conveyor II. According to the blank conveying machine, a rack is provided with a longitudinal guide rail assembly, a moving beam longitudinally moves along a longitudinal guide rail, a transverse guide rail assembly is arranged on the moving beam, a moving frame transversely moves along a transverse guide rail and is provided with a vertical lifting mechanism and a rotation mechanism, and the up-down motion and 90-degree turning are achieved. A clampinghand component is arranged below the rotation mechanism, and brick blanks on the grouping belt conveyor I are rapidly transferred to the grouping belt conveyor II, meanwhile, gaps between the brick blanks are adjusted through
