[0043] In order to make the purpose, technical solutions and advantages of the application more clear, the technical solutions in the application will be described clearly and completely in the following with reference to the drawings in the application. Obviously, the described embodiments are some embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the application.

[0044] The following will describe a welding supervision auxiliary method provided by the application, which comprises: Figure 1

[0045] ​S1, after obtaining product drawings of a product to be welded, extract all welding seam information in the product drawings and welding processes corresponding to each of the welding seam information. Specifically, after obtaining product drawings of a product to be welded, welding expert system is used to extract all welding seam information in the product drawings, and all welding seams are divided according to the process flow, and welding processes are generated, so as to obtain welding processes corresponding to each of the welding seam information. Taking a vehicle bogie side beam component as an example, after obtaining product drawings of the side beam component, the product drawings contain all welding seam information of the component from sheet metal to finished product. The side beam welding process is divided into multiple processes in sequence, such as inner rib welding, outer body welding and accessory welding. The component is transferred between different welding stations to gradually form the final product. The objects and welding seams required for each process are different, resulting in that the welding seams to be supervised are distributed in each process. Therefore, it is necessary to first divide the relevant information in the side beam product drawings according to the process, so as to obtain the process of the welding seams to be supervised and carry out subsequent work, and generate welding processes in the expert system. The welding expert system is a data management software based on B / S network structure design mode and using JAVA programming language.

[0046] S2, based on preset welding seam quality level information, mark the welding seams to be supervised in all the welding seam information to obtain all the marked welding seam information. Specifically, the preset welding seam quality level information is, for example, according to the EN15085 standard, the quality level of the welding seam has seven levels of CPA, CPB1, CPB2, CPCA, CP C2, CP C3 and CP D, wherein the three levels of CPA, CPB1 and CPB2 need to be supervised before, during and after welding. The three levels of CPA, CPB1 and CPB2 are marked by the welding expert system to obtain all the marked welding seam information. The omission of the welding seams to be supervised is avoided.

[0047] S3, based on the welding seam information, welding process and preset structure model, build a product process structure. Specifically, based on the welding seam information, welding process and preset structure model, a product lifecycle management system (PLM system) is used to build a product process structure. Preferably, the step S3 is executed simultaneously with or after the step S2.

[0048] S4, based on the product process structure, associate each marked welding seam information with the corresponding station to obtain all the supervision nodes. Specifically, based on the product process structure, a manufacturing execution system (MES system) is used to transmit each marked welding seam information to a mobile terminal of the station corresponding to each marked welding seam information for association to obtain all the supervision nodes. The MES system can form a closed loop control, effectively ensuring the completeness of the supervision.

[0049] S5, acquiring the work station of the component flow of the product by using the identification unit to obtain the work station information of the component flow. In the embodiment, the identification unit uses an RFID system, and the RFID system is responsible for recording the flow information of the components between work stations, and further acquiring the work station of the component flow of the product to obtain the work station information of the component flow.

[0050] S6, if the work station information of the component flow is any of the supervision nodes, activating the supervision node at the flow and sending the work station information at the flow to the supervisor. Specifically, when the component flows to the work station with the supervision node, the RFID system can be used to activate the supervision node and drive the mobile terminal to send the work station information at the flow to the supervisor. The supervisor can always master the situation of the key and important welds, thereby avoiding missed supervision.

[0051] The present application extracts all weld information and welding process corresponding to each weld information, uses a preset structure model to build a product process structure, marks the welds that need to be supervised according to the preset weld quality grade information, thereby obtaining all marked weld information, and then uses the product process structure to associate all marked weld information with the work station to obtain all supervision nodes. After acquiring the work station information of the component flow, the supervision node at the flow is activated, and the work station information at the flow is sent to the supervisor, so as to assist in prompting or reminding the supervisor and avoid missed supervision of the key and important welds by the supervisor.

[0052] On the basis of the above embodiment, based on the weld information, welding process and preset structure model, the product process structure is built, comprising:

[0053] The weld information and welding process are distributed to the process nodes in the preset structure model. In the embodiment, the PLM system is used to transmit the weld information, welding process and other related data to the process nodes of the corresponding preset structure model.

[0054] The distributed process nodes are associated with the work stations in the work station database in the preset structure model to build the product process structure, so that the work station corresponding to each weld is determined.

[0055] On the basis of the above embodiment, after the step of marking the welds that need to be supervised in all the weld information based on the preset weld quality grade information to obtain all the marked weld information, the method further comprises:

[0056] Based on the welding seam information of each of the marks and the welding process corresponding thereto, a supervision template is generated by using preset supervision points and supervision content. Specifically, the supervision points and content are compiled according to the welding seam information and the welding process by using a PLM system. The welding seam information and the welding process include quality requirements in three stages of before, during and after welding of the welding seam, including requirements such as joint form, bevel angle, assembly gap and personnel qualification before welding, corresponding to the content and qualified standards of pre-welding supervision; welding parameters and temperature control requirements during welding, corresponding to the content and qualified standards of welding process supervision; and information such as welding seam size, defect level and inspection level after welding, corresponding to the content and qualified standards of post-welding supervision. The supervision template is generated by using the PLM system, and the supervision template includes part information, supervision content and qualified standards.

[0057] If the work station information of the part flow is any of the supervision nodes, a supervision module is sent to the supervisor so as to generate a supervision report after the supervisor fills in the supervision module. In the embodiment, if the work station information of the part flow is any of the supervision nodes, a supervision module is sent to the supervisor by using a quality management system (QMS system) so as to generate a supervision document after the supervisor fills in the supervision module.

[0058] On the basis of the above embodiment, if the work station information of the part flow is any of the supervision nodes, a supervision module is sent to the supervisor so as to generate a supervision report after the supervisor fills in the supervision module, and the step is further followed by:

[0059] The supervision report is saved by using a quality management system. The supervision document is saved together with the rest of the quality records of the product until the product is decommissioned, so as to realize that each welding seam is subjected to supervision and closed-loop control, and to improve the supervision and management level of important and critical welding seams in the welding process.

[0060] On the basis of the above embodiment, the step of, if the work station information of the part flow is any of the supervision nodes, activating the supervision node at the flow station and sending the work station information at the flow station to the supervisor is further followed by:

[0061] After the supervision report is saved, the activated supervision node is closed. The activated supervision node is closed so as to better supervise the important and critical welding seams of the next part.
