Aluminum substrate lossless placing rack

The utility model relates to the technical field of aluminum substrate processing, in particular to an aluminum substrate lossless placing frame which comprises a frame body, a plurality of placing plates are transversely arranged on the frame body, a plurality of placing grooves are formed in the upper surfaces of the placing plates, chamfering plates are arranged at the corners in the placing grooves, compression springs are oppositely arranged on the inner side walls of the placing grooves, and the compression springs are arranged on the inner side walls of the placing grooves. The aluminum substrate body is placed in the placing groove, the opposite side faces of the limiting block are the cambered surfaces, the radian of the cambered surfaces is matched with that of the aluminum substrate body, and meanwhile, the compression spring plays a buffering role, so that the outer side of the aluminum substrate body can be protected. Damage to the outside of the aluminum substrate body during carrying of the pla
