Description

Technical Field

[0001] The present application relates to the technical field of steel bar detection, and in particular to an inspection method and system integrating three detection units of stretching, reverse bending and weight deviation. Background Art

[0002] Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs is spiral, herringbone, and crescent. It is expressed in millimeters of nominal diameter. The nominal diameter of ribbed steel bars is equivalent to the nominal diameter of plain round steel bars with equal cross-sections. The nominal diameter of steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm. The full diameter is 6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, and 50. Ribbed steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, ribbed steel bars have a greater bonding ability with concrete, so they can better withstand the effects of external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. Due to the effect of the ribs, deformed steel bars have a greater bonding ability with concrete, so they can better withstand the effects of external forces. Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

[0003] Since steel bars are widely used in various building structures, their quality needs to be tested. However, in the prior art, inspection items are scattered, and tensile inspection, weight deviation measurement and bending inspection are independent units. Inspection items form local islands, and there are breakpoints in the inspection process. There is available waiting time or actions between inspection item actions, which causes a waste of time and makes the inspection efficiency low. Summary of the invention

[0035] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0036] First, the application scenarios to which this application can be applied are introduced. This application can be applied to steel bar detection scenarios.

[0037] After research, it was found that in the existing technology, the inspection items are scattered, and the tensile test, weight deviation measurement and bending test are independent units. The inspection items form local islands, there are breakpoints in the inspection process, and there is available waiting time or actions between the inspection item actions, which causes a waste of time and makes the inspection efficiency low.

[0038] Based on this, an embodiment of the present application provides an inspection method that integrates three detection units: stretching, reverse bending, and weight deviation. Other inspections of the target to be inspected are completed during the waiting period when the target to be inspected is undergoing stretching processing. The inspection items are changed from the original series form to a parallel and simultaneous mode, thereby shortening the overall inspection time.

[0039] like Figure 1 As shown in , the inspection method of the three integrated detection units of stretching, bending and weight deviation provided in the embodiment of the present application includes:

[0040] S101, obtaining basic attribute information of a target to be detected, wherein the basic attribute information includes type data, length data, and width data of the target to be detected;

[0041] Steel type (steel varieties HRB400E B500B 30MnSi, etc.), steel specifications (steel diameter), steel furnace number, test serial number, test execution product standard (GB / T228.1-2010, etc.).

[0042] S102, determining a detection scheme for the target to be detected based on the basic attribute information and the detection standard;

[0043] S103, performing stretching processing on the first target to be detected according to the detection scheme to obtain detection data of the first target;

[0044] S104, while the first target to be detected is being stretched, measuring the length, weighing and bending the second target to be detected to obtain detection data of the second target, wherein the first target and the second target belong to the same batch of samples to be detected;

[0045] S105: Import the detection data of the first target and the detection data of the second target into the trained recognition model to obtain the detection result of the target to be detected.

[0046] In a possible implementation, the detection scheme includes: an information entry step, a length measurement and weighing step, a stretching step, a bending step, and a result reporting step.

[0047] The test items are changed from the original series form to a parallel and simultaneous mode to shorten the overall test time. The tensile test time is used to complete the weight deviation test (length measurement, weighing) and the reverse bending test of the sample, shortening the test cycle.

[0048] like Figure 3 As shown, in a possible implementation manner, the step of determining the detection scheme of the target to be detected based on the basic attribute information and the detection standard includes:

[0049] The information input step, the length measurement and weighing step, the stretching step, the bending step and the result reporting step are divided into 43 actions;

[0050] The 43 actions are reorganized based on the ECRS principle to determine the detection scheme of the target to be detected, wherein the reorganization condition satisfies that the target to be detected is subjected to length measurement, weighing and bending during the waiting stage for the stretching treatment of the target to be detected.

[0051] Combining the distribution of the inspection items and the distribution of the main experimental action rhythm time, the longest time is the stretching test, which takes longer than the sum of the weight deviation and bending tests;

[0052] Inspection process disassembly and reconstruction: The inspection items and 5 steps within the system were disassembled into 43 actions and reorganized according to the ECRS principle, making full use of the time of the tensile test to conduct weight deviation and reverse bending experiments, so that the tests that were conducted in series sequence can be converted into parallel synchronous tests, which can shorten the cycle by 32%.

[0053] After ECRS analysis, the inspection process was broken down into 43 actions, of which 7 actions were canceled, 8 actions were merged, 10 actions were rearranged, and 17 actions were simplified. The actions that can be replaced by the robot include: moving samples, taking and placing samples, assisting in weighing, automatic length measurement, retaining samples, discarding samples, etc.

[0054] The ECRS principle (cancel, merge, adjust, simplify) splits the entire experimental process into 43 actions, removes unnecessary actions and steps, merges some steps, adjusts and simplifies, and organizes it into 29 actions.

[0055] Restructure the process and integrate all tests into one test loop

[0056] The robot replaces the manual inspection part, makes different judgments according to different needs, and then executes the current priority program. It will also judge whether to throw away or keep the samples for review and retesting.

[0057] In a possible implementation manner, the step of reorganizing the 43 actions based on the ECRS principle to determine the detection scheme of the target to be detected includes:

[0058] Based on the ECRS principle, the 43 actions are deleted, merged, rearranged and simplified to determine the detection scheme for the target to be detected.

[0059] In a possible implementation manner, the step of reorganizing the 43 actions based on the ECRS principle to determine the detection scheme of the target to be detected further includes:

[0060] The 43 actions are screened to obtain actions that can be replaced by the robot;

[0061] The robot is controlled based on the replaceable actions of the robot to complete the replacement.

[0062] In a possible implementation, Figure 2 As shown, the present application provides an inspection system integrating three detection units of stretching, bending and weight deviation, including:

[0063] The information acquisition module 201 is used to acquire basic attribute information of the target to be detected, wherein the basic attribute information includes type data, length data and width data of the target to be detected;

[0066] The second detection module 204 is used to measure the length, weigh and bend the second target to be detected when the first target to be detected is stretched, so as to obtain detection data of the second target, wherein the first target and the second target belong to the same batch of samples to be detected;

[0067] The data analysis module 205 is used to import the detection data of the first target and the detection data of the second target into a trained recognition model to obtain the detection result of the target to be detected, wherein the recognition model is a visual model through a recognition map.

[0068] Optional, such as Figure 4 As shown, the detection module includes: a tensile testing machine 1, a repeated bending testing machine 2, an electric dotting machine 3, an electronic balance 4 and a length ruler 5;

[0069] Among them, the electric dotting machine 3, the electronic balance 4 and the length ruler 5 are located on the length measuring and weighing device. The length measuring and weighing device, the tensile testing machine 1 and the repeated bending testing machine 2 are integrated in the same space, and the sampling and transfer process of the samples to be tested are completed by a robotic arm.
