Embodiment 1

[0060] Such as image 3 As shown, the automatic generation system of the resistance spot welding process parameters includes: a data acquisition unit 1, the data acquisition unit 1 communicates with the data server in the resistance spot welding workshop through the Internet of Things, and is used to obtain the plate information parameters stored in the data server, Welding process parameters and welding result parameters;

[0061] The evaluation function construction unit 2 is used to establish the welding result evaluation function according to the welding result parameters; specifically, the welding result evaluation function is constructed by the following calculation formula;

[0062]

[0063] Among them, F is the welding result evaluation value; UIP is the quality factor; f is the spatter value; PSF is the process stability factor;

[0064] The model building unit 3 is used to use the plate information parameters and welding process parameters as input, and use the w...

Embodiment 2

[0087] Such as figure 2 As shown, the technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that the welding result prediction value of the specific plate information parameter is predicted according to the welding result prediction model, and then the corresponding specific plate information parameter is generated. After the welding process parameters with the highest welding result prediction value, it also includes:

[0088] The welding process parameters with the highest welding result prediction value are integrated to form a database of optimal welding process parameters under different plate information parameters. The establishment of the database can directly obtain the optimal welding process parameters according to the plate information parameters in the later use. The itinerary of the database can also be used as the initial setting value of the welding process parameters when the welding commissi...

Abstract

The invention provides a resistance spot welding process parameter automatic generation method and system, and belongs to the technical field of automobile welding manufacturing. The problems that in the prior art, obtained welding parameters cannot be determined to be optimal parameters, and the welding quality of each welding spot cannot be guaranteed are solved. The resistance spot welding process parameter automatic generation method comprises the following steps that plate information parameters, welding process parameters and welding result parameters are obtained; a welding result evaluation function is established according to the welding result parameters, and then a welding result evaluation value is obtained through calculation according to the welding result evaluation function; the plate information parameters and the welding process parameters serve as input, the welding result evaluation value serves as output, and therefore a welding result prediction model is established; and a welding result prediction value of the specific plate information parameter is predicted according to the welding result prediction model, and a welding process parameter with the highest welding result prediction value corresponding to the specific plate information parameter is further generated. According to the method, high-quality welding process parameters can be obtained, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile welding and manufacturing, and relates to a method for determining resistance spot welding process parameters and a system thereof. Background technique [0002] At present, there are more and more new models launched by major automobile manufacturers, and the time interval between launches is getting shorter and shorter. At the same time, users have higher and higher requirements for quality. As far as manufacturing plants are concerned, various innovative process technologies must be used to win. Resistance spot welding (hereinafter referred to as welding) can realize high-strength connections between plates. In automobile manufacturing, a car contains 3000-5000 resistance spot welding spots, and the welding quality of each spot directly affects the vehicle. safety performance. Therefore, welding is one of the most core processes in vehicle manufacturing, and how to quickly debug the parame...
