[0043] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0044] Figure 1 A flow chart of a solder joint automatic management method provided by the present invention, such as Figure 1 As shown, the method includes:

[0045] S1. Create multiple areas according to the vehicle and number each area, create the three-dimensional coordinate points of the required welding points in each area, and assign corresponding welding point attribute information to each welding point;

[0046] S2. Associating each soldering point with its related connector, and assigning the connector attribute information corresponding to each soldering point;

[0047] S3. Determine in turn whether the number of solder joints at each of the three-dimensional coordinate points is accurate. If the number of solder joints is inaccurate, output an error data list, correct the number of solder joints at the corresponding three-dimensional coordinate points according to the error data list, and then re-determine until the number of solder joints at all three-dimensional coordinate points is accurate;

[0048] S4. Number all solder joints according to the region number, and output the number, solder joint attribute information and connector attribute information corresponding to each solder joint.

[0049] It is understandable that based on the defects in the background technology, the embodiment of the present invention proposes a method for automatic management of welding points. Based on this method, the present embodiment can realize automatic processing of welding point information through CATIA software, standardize welding point numbers, and the upstream and downstream processes can know the welding point positions of various parts of the automobile according to the welding point numbers; at the same time, the accuracy of welding points is guaranteed, ensuring that all points have welding points, and avoiding the situation of multiple welding points in one coordinate; the present invention also greatly improves the efficiency of welding point writing and processing, and the welding point list of the whole vehicle can be output in a few minutes to avoid manual maintenance errors.

[0050] In a possible embodiment, Figure 2 As shown, step S1 includes:

[0051] S101. Create multiple regions in CATIA according to the vehicle information, each region corresponds to a PART file, and set a region number for each region, for example, the multiple PART files are numbered as FF10, RF10, etc.;

[0052] S102. Select the connectors to be welded in each area in turn, determine the three-dimensional coordinate points of the required welding points according to the positions of the connectors, and set welding point attribute information for each welding point.

[0053] It can be understood that in step S1, the connecting parts here correspond to the parts that need to be welded on the car, such as part 1 and part 2 that need to be connected through the current welding point.

[0054] In a possible implementation manner, the weld point attribute information includes: welding type and / or number of welding layers, wherein the welding type includes at least any one of spot welding and arc welding.

[0055] It is understandable that in step S1 of this embodiment, the welding type (such as spot welding, arc welding) and the number of welding layers of the current welding point are assigned to the current welding point as the attribute information of the welding point. All welding points are traversed until the corresponding attribute information is assigned to all welding points.

[0056] In a possible implementation manner, step S2 includes:

[0057] A three-dimensional model of the welding points is generated according to the three-dimensional coordinate points of all welding points, the connecting parts to be welded are associated with the three-dimensional model, and the connecting part attribute information of the connecting parts is assigned to the corresponding welding points.

[0058] It is understandable that in this embodiment, the welding points and the connecting parts to be welded are associated with the same three-dimensional model, and then the attribute information of the connecting parts is assigned to the corresponding welding points, so as to facilitate the unified management of the connecting parts and welding points in subsequent processes.

[0059] In a possible implementation manner, the above-mentioned connector attribute information includes at least but is not limited to: any one or more of the connector number, connector name, connector material brand, connector material thickness, connector plating, connector process code, and connector appearance requirements.

[0060] In a possible embodiment, in step S3, determining in turn whether the number of welding points at each of the three-dimensional coordinate points is accurate includes:

[0061] Confirm the number of welding points on the three-dimensional coordinate point corresponding to the required welding points in each area respectively. If the number of welding points on the three-dimensional coordinate point is one, it is determined that the number of welding points on the three-dimensional coordinate point is accurate; if the number of welding points on the three-dimensional coordinate point is multiple or there is no welding point on the three-dimensional coordinate point, it is determined that the number of welding points on the three-dimensional coordinate point is inaccurate;

[0062] Traverse all the solder joints in all areas until the number of solder joints at the three-dimensional coordinate points of all required solder joints is confirmed.

[0063] It is understandable that judging whether the number of welds at each of the three-dimensional coordinate points is accurate is to ensure the accuracy of the welds, ensure that all points have welds, and avoid the situation of multiple welds at one coordinate, thereby standardizing the weld numbering in subsequent steps.

[0064] In a possible embodiment, Figure 3 As shown, step S4 includes:

[0065] S401. Determine whether the current solder joint is numbered for the first time. If it is numbered for the first time, execute step S402. If it is not numbered for the first time, execute step S403.

[0066] S402. Clear the historical data on the three-dimensional coordinate point corresponding to the current solder joint, and number the solder joints according to the area number and serial number corresponding to the current solder joint;

[0067] S403. Specify the storage path in the Excel table for the new number, number the solder joints according to the area number and serial number corresponding to the current solder joint, calculate the number addition, modification, deletion, and mark;

[0068] S404. Output the number, solder point attribute information and connector attribute information corresponding to each solder point in the form of an Excel spreadsheet.

[0069] It can be understood that this step is to standardize the numbering of each solder joint. After numbering all solder joints, a table file corresponding to the number of each solder joint, solder joint attribute information, and connector attribute information is generated, and the number update is marked to achieve unified management of solder joints. In subsequent processes, this table can be used to intuitively understand the corresponding situation of all solder joints and connectors, which is convenient for automated management of solder joints.

[0071] The welding point creation module is used to create multiple areas according to the whole vehicle and number each area, create the three-dimensional coordinate points of the welding points required in each area, and give each welding point its corresponding welding point attribute information;

[0072] An information association module is used to associate each soldering point with its related connectors and assign corresponding connector attribute information to each soldering point;

[0073] An error correction module is used to determine in turn whether the number of solder joints at each of the three-dimensional coordinate points is accurate. If the number of solder joints is inaccurate, an error data list is output, and the number of solder joints at the corresponding three-dimensional coordinate points is corrected according to the error data list, and then the judgment is repeated until the number of solder joints at all three-dimensional coordinate points is accurate.

[0074] The number output module is used to number all solder joints according to the area number and output the number, solder joint attribute information and connector attribute information corresponding to each solder joint.
