9. A method for unmanned concrete specimen strength testing according to any one of claims 1-8, characterized in that, Includes the following steps: S1. Concrete block sampling: The sampling trolley moves and places the sampling hopper at the designated position below the discharge port of the mixing host. The mixing host discharges the material, and the weighing sensor weighs the material. The mixing host stops discharging the material after the set weight is reached. S2. Concrete Specimen Molding: The transport trolley inserts the painted and pasted mold box into the receiving hopper of the molding device. The molding cylinder pushes the feeding hopper into position. The sampling hopper of the sampling trolley moves past the closing trigger wheel to the feeding hopper and makes the sampling hopper face the feeding hopper. During this process, the discharge trigger rod pushes the upper part of the hook, so that the hook head disengages from the hanging rod, the blocking plate opens, and the concrete in the sampling hopper falls from the feeding hopper into the mold box. At the same time, the vibrator works to make the concrete vibrate evenly. Then the molding cylinder pushes the feeding hopper to move. After the screed plate smooths the concrete in the mold box, the molding cylinder resets, completing the feeding into the molding device. After feeding is completed, the sampling trolley moves backward, the closing trigger wheel lifts the blocking plate, and the hook head is hooked on the hanging rod. The transport trolley inserts the mold box again and transports it to the temperature and humidity controlled curing room for static treatment for 24 hours. S3. Concrete Specimen Demolding: The transport trolley picks up the mold box containing the settled concrete specimens and transports it to the demolding platform in the demolding device. Then, the transport trolley picks up the pallet and moves it to the demolding device, positioning the pallet below the top plate. The tilting cylinder extends to make the demolding platform vertical. The top plate moves up and down through the demolding linear module to hold the mold box in place. Compressed air is sprayed from the nozzles corresponding to the concrete specimens not blocked by the top plate, blowing the concrete specimens out and onto the pallet. The transport trolley adjusts the position of the pallet through the lifting linear module, positioning the concrete specimens between the two clamping plates. The screw slide module moves to clamp the concrete specimens and prevent them from falling. The transport trolley then transports the pallet to the curing room for curing the concrete specimens and picks up a new pallet to continue demolding. After all the concrete specimens in the mold box have been sent to the curing room, the tilting cylinder resets, and the transport trolley picks up the empty mold box after demolding and transports it to the cleaning device. S4. Concrete Specimen Pressure Testing: The transport trolley picks up a pallet containing cured concrete specimens and transports it to the rotating platform of the pressure testing device. The rotating cylinder moves the pallet from horizontal to vertical. The gripper picks up a concrete specimen and places it on the testing platform through the dual-axis linear module. The cylinder moves to push the pusher plate to push the concrete specimen under the pressure testing machine for pressure testing. After the test is completed, the cylinder pushes the waste and residue to the other end of the testing platform. Then the transport trolley picks up the empty pallet and picks up another pallet containing cured concrete specimens for testing. S5. Cleaning of the mold box: After the mold box from step S3 is transported to the cleaning device, the cleaning gripper grabs the mold box, and the cleaning rotary cylinder flips the mold box. Under the action of the cleaning dual-axis linear module, the mold box is placed in the cleaning tank with the opening facing down. After the ultrasonic cleaning in the cleaning tank is turned on for a period of time, the mold box is sent to the brushing tank. The brush is inserted into the nine-square grid structure of the mold box and is brushed by the up and down movement of the cleaning dual-axis linear module. Then the mold box is sent to the drying tank, and the drying nozzle sprays air to dry the mold box. Then the cleaning gripper places the cleaned mold box on the transfer cart and transports it to the storage location. S6. Spraying and Labeling the Mold Box: Before step S2, the transfer trolley picks up the mold box from the storage area and transports it to the positioning frame of the spraying and labeling device. A label box containing the label is placed under the spray nozzle. The spraying cylinder is activated, causing the spray nozzle to rise and pass through the vent. Then, the spray nozzle atomizes and sprays concrete block release agent onto the four walls inside the mold box. The spraying cylinder then resets, and at the same time, the suction cup, driven by the paper suction cylinder, picks up the label and then resets. The shifting cylinder is activated, pushing the positioning frame to move the mold box under the suction cup. The spraying cylinder is activated again to insert the suction cup into the mold box to place the label and then resets. After completing the spraying and labeling operation, the transfer trolley sends the mold box to the molding device for molding.
