The existing steel bar detection flow is required to cut the two ends of the steel bar flat by a cutting machine according to the standard requirements, then the length of the sample is measured by a steel ruler one by one, the length is accurate to 1mm, and the steel bars are respectively measured and manually input into a computer. The weight of the bar is weighed by a balance and manually entered into a computer. The method has poor efficiency and low accuracy, the length measurement needs to be read manually, and the error of manual operation is large.
In the prior art, the length of the steel bar is generally measured by using an advanced digital display type displacement sensor, the length of the steel bar is equal to the initial length minus the displacement, the steel bar is then connected with an electronic weighing scale data line, weight data are transmitted in real time, the diameter of the steel bar is input into a display screen, and then the detection result is calculated; however, the method also needs manual work to move the steel bars for many times, and the input process of the diameter of the steel bars is also manual input, so that errors are easy to occur, and only about 5 to 10 steel bars can be measured at one time, so that the efficiency of the method is not high. In addition, CN106706090a discloses a steel bar weight deviation detecting instrument, and the measuring module of the device is combined with the weighing module, so that the length and the weight can be measured at one time, but only one piece can be measured at one time, and the efficiency is not high. CN214277773U discloses a digital detecting system for weight deviation of steel bar, which combines measurement and weighing together and transmits the data measured in real time to a computer, however, the system can only measure the weight deviation data of one steel bar at a time, and the length measurement process can have a certain influence on the weight measurement due to the combination of measurement and weighing together, so the efficiency of the method is not high; and the device can only measure the length and the weight of the reinforcing steel bars with fixed diameters. CN210862870U also discloses a steel bar weight deviation detector, which can test the lengths of a plurality of steel bars at a time, however, more than 5 distance meters and weighing devices need to be provided, and one steel bar corresponds to one distance meter and one weighing device; and the diameters of the reinforcing steel bars in each group are required to be the same, the arrangement is heavy and complicated, and the cost is high. CN217586007U discloses an intelligent steel bar weight deviation detecting system, and this system is through weighing assembly and measuring assembly's cooperation, carries out whole weighing to the reinforcing bar, and the batch length measurement, however this system also has some drawbacks, namely: 1) In the length measurement process, the millimeter is taken as the minimum unit of measurement, the fixed pitch of the ball screw is set to be 10mm, and the rotation number is multiplied by the pitch to obtain the length of the steel bar test piece, wherein the accuracy of the length is poorer than that of the laser range finder; 2) When the total weight of the steel bars is measured, manual real-time recording and comparison are also needed, and efficiency is reduced; 3) The system equipment is provided with a plurality of sensors, the structure is extremely complex, the manufacturing cost is high, and the economy is poor.
