Description

Technical Field

[0001] The present invention relates to the technical field of information management, and in particular to an information management device for assembled steel structure components and a management method thereof. Background Art

[0002] Prefabricated steel structure is a composite steel structure component made of steel plates, angle steels, channel steels, I-beams, and welded H-shaped steels that can bear and transfer loads. Due to the different designs of building structures, the required steel structure design is relatively complex and special. For example, large-span and high-load-bearing welded H-shaped steel is made by welding a web between two wing plates using welding technology. The production process of the welded H-shaped steel is simple, the cost is lower than that of hot-rolled H-shaped steel, and the size and model can be customized at will. Therefore, this type of steel component is reasonably and widely used in the field of prefabricated building projects.

[0003] With the advancement of automatic welding technology, when welding H-beams, a welding trolley is used to drive the welding gun head to move at a constant speed. This is suitable for long-distance welding of the weld between the web and the wing plate. After welding is completed, a weld flaw detector is used to detect the weld, and the welded workpiece is measured and compared with the workpiece design parameters to ensure the welding quality. The welding defects usually detected at the weld are mainly defects such as lack of fusion, slag inclusions, and pores. At this time, the detected defective points need to be manually repaired.

[0004] At present, although automated welding has been achieved in the production of steel components, the quality of welding cannot be monitored, and the approximate area where welding defects occur cannot be analyzed. Therefore, when inspecting the welding quality of welds, it is necessary to manually use a weld flaw detector to conduct a full-length inspection. The inspection process is time-consuming and slow. In addition, the specific production information and product information of the steel structure cannot be managed, which is not conducive to the technicians using the same technical means to deal with welding defects during rework, nor is it conducive to the maintenance of steel components after use. Summary of the invention

[0005] Technical issues solved

[0006] In view of the deficiencies in the prior art, the present invention provides an information management device and a management method for prefabricated steel structure components, which can analyze and determine the approximate fault point location of welding defects during the welding process, and can also record and manage the specific production information and product information of the steel structure, so as to facilitate technicians to inquire about the welding process for rework and the subsequent maintenance of the steel components. It solves the problem that the quality of welding cannot be monitored during the automated welding production of steel components, and the approximate area where welding defects occur cannot be analyzed, and manual full-length inspection with a weld flaw detector is required. In addition, the specific production information and product information of the steel structure cannot be managed, which is not conducive to technicians using the same technical means to deal with welding defects during rework, and is also not conducive to the maintenance of the steel components after use.

[0007] Technical Solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an assembled steel structure component information management device, applied to an automatic welding mechanism, comprising:

[0009] An industrial computer, wherein the industrial computer stores the workpiece design parameters obtained when welding the workpiece and the optimal welding process scheme required to be adopted when welding the workpiece;

[0010] An optical and visual monitor, which optically monitors the welded workpiece throughout the entire process and obtains an overall image of the workpiece after welding;

[0011] The welding information manager collects the circuit information of the automatic welding mechanism during welding through the welding parameter collector, and synchronously monitors the position change information of the automatic welding mechanism through the welding position positioning module, compares the workpiece design parameter data obtained from the industrial computer with the actual data of the workpiece collected by the optical and visual monitor, and gives the comparison results and processing solutions.

[0012] Preferably, the industrial computer is provided with a database for acquiring and storing workpiece design parameters and workpiece groove geometric parameters, and is provided with a knowledge base for storing the welding process selected before the workpiece is welded, including the process number, welding process specification, welding materials, welding equipment, welding fixtures, the shape and size of the workpiece groove, and the change record of the welding process during the welding process. The industrial computer receives the data collected by the optical and visual monitor and transmits it to the welding information manager for processing.

[0013] Preferably, the optical and visual monitor controls the laser sensor and the industrial camera by the laser and visual sensor control system to monitor the whole process of welding the workpiece. The laser sensor first collects the material, shape, size, groove position, angle, gap, misalignment and cross-sectional area of ​​the welding workpiece components and transmits them to the industrial computer and compares them with the data in the database. According to the comparison result, the corresponding welding scheme is selected, and the wire feeding speed and welding current of the automatic welding mechanism are controlled accordingly. During the welding process, the laser sensor collects the geometric parameters of the groove of the workpiece in real time, and together with the welding parameter library, establishes the quantitative relationship between the welding dynamic parameters and the geometric shape of the groove to be welded and the weld formation quality, so as to realize the weld formation quality control;

[0014] The industrial camera is used to collect the appearance picture of the workpiece after welding, and extract the 3D size of the workpiece in the picture to generate a 3D model. The welding information manager compares the model with the workpiece model in the database, and gives the analysis result to judge the defects of the workpiece.

[0015] Preferably, the welding information manager is provided with a basic information management unit, a monitoring data processing unit and a rework quality recording unit. The basic information management unit records the use of the process when welding the workpiece, and is also used to query the welding process, user management and query the workpiece number information. The rework quality recording unit is used to store the defect record, rework processing record and manual inspection record of the workpiece;

[0016] The monitoring data processing unit is used to process the monitoring data of the optical and visual monitors, and records the data of circuit information changes and the time nodes when the changes occur according to the circuit information data of the automatic welding mechanism collected by the welding parameter collector during welding, and records the position of the automatic welding mechanism through the welding position positioning module when the time node occurs, so as to generate a fault point, record the fault point in the workpiece defect record, and focus on troubleshooting and repair after welding.

[0017] Preferably, the welding parameter collector collects circuit information data including welding current and welding voltage through the sensor component. The welding current and welding voltage are transmitted to the database together with the groove information collected by the optical and visual monitor. According to the welding process records in the database, the corresponding welding process is selected again, and the welding speed and wire feeding speed of the automatic welding mechanism are adjusted to adapt to the corresponding current.

[0018] The present invention also provides a method for managing information of assembled steel structure components, which is applied to an automatic welding mechanism and includes the following steps:

[0019] Before welding, the workpiece design parameters stored in the industrial computer are used to select the best welding process plan when welding the workpiece;

[0020] During welding, the optical and visual monitor collects the circuit information of the automatic welding mechanism during welding through the welding parameter collector, and synchronously monitors the position change information of the automatic welding machine through the welding position positioning module, and performs optical inspection on the welded workpiece throughout the process;

[0021] After welding, the welding information manager is used to compare the workpiece design parameter data obtained from the industrial computer with the actual workpiece data collected by the optical and visual monitor, and the comparison results and processing solutions are given.

[0024] 1. When the present invention is in use, by comparing the workpiece design parameter data obtained from the industrial computer with the actual data of the workpiece during welding collected by the optical and visual monitor, a comparison result and a processing scheme are given, that is, when the current and voltage fluctuate, the welding information manager controls the wire feeding speed and the walking speed of the automatic welding mechanism to ensure the best welding effect, and makes corresponding time and position records at the starting point and the end point of the current and voltage fluctuations as the locations where welding defects may occur, and focuses on manual inspection and rework after welding.

[0025] 2. The welding information manager provided in the present invention, when in use, records the data of changes in voltage and current and the time nodes of the changes, that is, the starting point and end point of the changes, based on the circuit current and voltage data of the automatic welding mechanism during welding collected by the welding parameter collector, and records the position of the automatic welding mechanism through the welding position positioning module when the time node occurs, thereby generating a fault point, recording the fault point in the workpiece defect record, and focusing on troubleshooting and repair after welding.
