Traditional inspections are mostly manually operated equipment inspections, but with the development of the construction industry, the inspection workload of the testing center is increasing. The steel bar inspection projects are mainly weight deviation inspections and tensile tests.

The shell is driven by the first motor to slide upward, and the test piece support groove completely lifts the test piece, so that the test piece is separated from the test piece placement groove. The weighing instrument at the bottom of the test piece support groove directly weighs the actual weight information of the test piece, and then the shell falls to put the test piece back into the test piece placement groove, and the detection pen slides outward to return to the initial position. The control system calculates the theoretical weight value and the allowable deviation value of the test piece through the actual length information and the test piece information, compares the actual weight value with the theoretical weight value to obtain the actual deviation value, and compares the actual deviation value with the allowable deviation value. If the actual deviation value is within the allowable deviation value, the weight deviation detection data of the test piece is recorded as qualified; if the actual deviation value exceeds the allowable deviation value, the weight deviation detection data of the test piece is recorded as unqualified; After the weight deviation detection is completed, the specimen fixture of the multi-axis robotic arm clamps the specimen, and after rotating the rotating head, the specimen is adjusted from a horizontal posture to a vertical posture, and then sent to the tensile testing machine for tensile testing. There are three groups of tensile testing machines. When the specimen is undergoing a tensile test in the first group of tensile testing machines, the weight deviation detection machine and the material taking mechanism can continue to detect the next group of specimens, and place the next group of specimens in the second group of tensile testing machines for tensile testing. Multiple groups of tensile testing machines can work in a staggered manner without waiting for the tensile testing machine to complete the stretching process, which greatly reduces the time for steel bar detection and improves efficiency.
