The invention provides a full-automatic intelligent maintenance and strength detection system for concrete test blocks. The full-automatic intelligent maintenance and strength detection system comprises a warehousing unit, a maintenance unit and a compression resistance testing unit. The warehousing unit comprises a first conveying line, a first tray and a code spraying/scanning assembly; the maintenance unit comprises a maintenance bin, a track, a maintenance frame and a stacking machine. According to the system, by adopting the technical means of an image recognition technology, the Internet of Things, automation, intelligent control, a robot and the like, the concrete test blocks can be automatically maintained and conveyed, and after compression resistance test units are integrated, the concrete test blocks can be automatically detected, so that the integration, automation and intelligentization of the concrete test block maintenance and strength detection process are realized, and the working efficiency is improved. The maintenance quality of the concrete test block is guaranteed, the detection process is managed and protected more finely, the detection efficiency is greatly improved, the detection quality is guaranteed, and the manual dependence is reduced.
