Abstract

The invention relates to an automated monitoring system of resistance spot welding process of a sedan body, which is realized by a hardware system and a software system and is characterized in that a hardware terminal acquiring display device comprises two parts, namely a spot welder monitor host and an actual parameter display extension set after welding operation, wherein the spot welder monitor host is provided with a Hall sensor for acquiring electrical parameters, executes acquiring treatment of the electrical parameters in the welding process and uploads the treated data results to a network personal computer for secondary treatment. The invention has the advantages as follows: the production progress is not stopped, and the quality of each welding point is endowed with traceability; the quality state of wielding points can be fed back in time and be informed to operators by voices in time, and the welding sealing-off phenomenon can be avoided by tracing and controlling current compensation in the welding process; the operators are informed timely to repair electrodes so as to realize management of electrode end surface and reduction of welding quality defects; and the system provides service for production management visualization.

Description

technical field [0001] The invention relates to an automatic monitoring system for the resistance spot welding process of a car body, which aims at eliminating the welding quality defects of missing welding and open welding in the spot welding welding process in the production process of the car body, and belongs to the field of car body monitoring. Background technique: [0002] The body is an important part of the whole car, and the quality of the body directly affects the service life of the car. The quality of body assembly and welding depends on the welding process mainly based on resistance spot welding (accounting for about 96% of the welding process of car body-in-white). Affected by many complicated factors such as human operation and human operation, quality defects are prone to occur, mainly manifested as open welding and missing welding of solder joints. According to the search in the same industry, the current domestic and foreign automobile industries generall...
