The automated process can accurately control the length, spacing and welding quality of the steel bars, reduce human errors, and ensure the consistency and quality of the prestressed positioning mesh. Automation reduces the direct contact between workers and mechanical operations, reduces the risk of work-related injuries, and improves the safety of the working environment. The application of image acquisition technology enables every link in the production process to be monitored in real time. Once a problem is found, a feedback signal can be immediately issued to facilitate timely adjustment and correction. The laying position of the steel bars can be accurately controlled to ensure the accuracy of the mesh. Through the refined automated process, not only the production efficiency and product quality are improved, but also the controllability and safety of the production process are enhanced.
[0050] By monitoring and evaluating the actual longitudinal spacing of a single point, it is possible to ensure that the length between each pair of adjacent target longitudinal reinforcements is qualified, thereby ensuring the accuracy and quality of the entire prestressed positioning mesh. The calculation of the point longitudinal spacing difference and the root longitudinal spacing difference helps to ensure that the position of each reinforcement in the prestressed positioning mesh is uniform and consistent, avoiding structural weaknesses caused by uneven material distribution. The real-time judgment and feedback signal mechanism can quickly identify and respond to any deviations in the material distribution process, so as to make timely adjustments. Through detailed analysis of the material distribution parameters, it can ensure that only qualified products can enter the next production stage, thereby improving the overall quality of the final product. By analyzing the abnormal change trend of the spacing difference , can distinguish whether the error is caused by abnormal material operation or abnormal straightening of the steel bar coil, which helps to quickly locate the source of the problem. The automated judgment process reduces the need for manual inspection, speeds up production, and improves production efficiency. Through continuous monitoring of the production process, it helps to maintain a safe working environment and reduce safety risks caused by equipment failure or operating errors. It records the judgment results and feedback signals of each step, and provides valuable data support for subsequent quality control and production improvements. The implementation of a one-time judgment process has brought a higher level of automation, better quality control, faster fault response and higher production efficiency to the production of prestressed positioning mesh.
[0051] By acquiring the actual layout image and marking the intersection position, the intersection of the transverse and longitudinal steel bars can be accurately identified, providing accurate position information for the welding operation. By fitting the intersection centerline and determining the actual fitting angle, the accuracy of the intersection welding is ensured, thereby improving the welding quality. The automatic determination of whether to start the intersection welding operation reduces manual judgment and operation, improves production efficiency, monitors the quality of the material distribution at the intersection in real time, and quickly responds to any deviation through the second-class feedback signal, allowing timely adjustments to avoid production delays. By ensuring that all intersections are properly distributed before welding, the process reduces rework and material waste caused by improper distribution. By analyzing the number of unqualified angles, the process can distinguish different types of abnormalities, such as abnormal straightening of the transverse steel bar coil or abnormal secondary distribution operation, which helps to solve the problem in a targeted manner. Accurate intersection welding reduces structural weaknesses caused by improper welding, improves the safety and reliability of the final product, ensures that the material distribution and welding quality of all intersections are consistent, and improves the uniformity and consistency of the entire prestressed positioning mesh product. The implementation of the secondary determination process brings accurate welding preparation, efficient automation control, real-time quality monitoring and effective fault diagnosis to the production of prestressed positioning mesh.

[0065] Step S600, welding is performed based on the intersection welding operation to obtain a target prestressed positioning mesh.
[0066] In this embodiment, the longitudinal steel bar coil is placed on a straightening machine for straightening. During the straightening process, the longitudinal steel bar passes through a series of straightening wheels to eliminate its internal stress and meet the linearity requirement. The straightened longitudinal steel bar is fed into a cutting machine, and the cutting machine automatically cuts according to the preset length parameters. For example, in the specific implementation process, the preset length of the target longitudinal steel bar is 6000mm and the diameter is 12mm; wherein, the straightening wheel spacing and pressure of the straightening machine are adjusted according to the steel bar diameter to ensure the straightening effect, and the cutting machine is set to cut out 6000mm long steel bars each time; in this embodiment, the straightening and cutting process of the transverse steel bar coil is consistent with the straightening and cutting process of the longitudinal steel bar coil, for example, the preset target transverse steel bar length is 3000mm and the diameter is 10mm, that is, the cutting machine is set to cut out 3000mm long target transverse steel bars each time; wherein, the setting of the longitudinal fixed spacing is affected by the design requirements and the specifications of the prestressed positioning mesh; in actual applications, the conveyable workbench is part of an automated conveyor line, such as a chain conveyor belt, a roller conveyor belt or a pneumatic conveying system, which is not specifically limited in this embodiment.
[0067] Specifically, for example, the longitudinal steel bar coil is straightened and cut to obtain a 6000 mm long longitudinal steel bar, and the transverse steel bar coil is straightened and cut to obtain a 3000 mm long transverse steel bar. The straightened and cut longitudinal steel bars are laid on the chain conveyor belt at a spacing of 200 mm, and the longitudinal laying parameters are obtained through image acquisition technology to make a judgment to determine whether to start the secondary laying operation. Based on the start of the secondary laying operation, the conveyor belt moves the longitudinal steel bars. When it reaches the welding position, the secondary laying of the transverse steel bars is carried out. The transverse steel bars cross the longitudinal steel bars. The transverse laying parameters are obtained through image acquisition technology, and a secondary judgment is made to determine whether to start the intersection welding operation. Based on the completion of all welding operations, the target prestressed positioning mesh is obtained.
[0068] In this embodiment, the intersection points of the transverse steel bars and the longitudinal steel bars are welded together by spot welding or other welding methods to form a mesh structure. The specific welding method is not specifically limited in this embodiment. The image acquisition technology refers to capturing the position and state of the steel bars by using various sensors and cameras, such as a high-resolution camera or a laser scanner, which is not specifically limited in this embodiment.
[0069] Specifically, the embodiments of the present invention significantly improve the production speed of prestressed positioning meshes through automated processes, reduce manual operation time, and thus improve overall production efficiency. The automated process can accurately control the length, spacing, and welding quality of the steel bars, reduce human errors, and ensure the consistency and quality of the prestressed positioning meshes. Automation reduces direct contact between workers and mechanical operations, reduces the risk of work-related injuries, and improves the safety of the working environment. The application of image acquisition technology enables every link in the production process to be monitored in real time. Once a problem is found, a feedback signal can be immediately issued to facilitate timely adjustment and correction. The laying position of the steel bars can be accurately controlled to ensure the accuracy of the mesh. Through a refined automated process, not only the production efficiency and product quality are improved, but also the controllability and safety of the production process are enhanced.

[0115] Specifically, the embodiment of the present invention can accurately identify the intersection of the transverse steel bar and the longitudinal steel bar by acquiring the actual layout image and marking the intersection position, provide accurate position information for the welding operation, and ensure the accuracy of the intersection welding by fitting the intersection center line and determining the actual fitting angle, thereby improving the welding quality. It automatically determines whether to start the intersection welding operation, reduces manual judgment and operation, improves production efficiency, monitors the quality of the material distribution at the intersection in real time, and quickly responds to any deviation through the second type of feedback signal, allowing timely adjustment to avoid production delays. By ensuring that all intersections are qualified before welding, the process reduces rework and material waste caused by improper material distribution. By analyzing the number of unqualified angles, the process can distinguish different types of abnormalities, such as abnormal straightening of the transverse steel bar coil or abnormal secondary material distribution operation, which helps to solve the problem in a targeted manner. Accurate intersection welding reduces structural weaknesses caused by improper welding, improves the safety and reliability of the final product, ensures that the material distribution and welding quality of all intersections are consistent, and improves the uniformity and consistency of the entire prestressed positioning mesh product. The implementation of the secondary determination process brings accurate welding preparation, efficient automation control, real-time quality monitoring and effective fault diagnosis to the production of prestressed positioning mesh.
