Automated Welding In The Automotive Field
Looking at the welding status of the entire automotive industry, it is not difficult to analyze the development trend of the automotive industry's welding: development of automated flexible production systems. Industrial robots, because of the combination of automated production and flexible production characteristics, have been used in large and rapid use of robots in recent years. In terms of welding, spot welding robots and arc welding robots are mainly used. Especially in recent years, domestic automobile manufacturers pay great attention to the automation of welding. For example, the automation rate of 13 production lines of the Jetta body welding shop introduced by FAW is over 80%, and each line is controlled by a computer (programmable controller PLC-3) to automatically complete the workpiece transfer and welding. The robot's action uses a point-to-point sequence trajectory with a high level of welding automation, which improves working conditions, improves product quality and productivity, and reduces material consumption.
In modern vehicles, whether it is exterior decorative parts (such as bumpers, fenders, wheel covers, deflectors, etc.), interior decorative parts (such as instrument panels, door inner panels, sub-dashboards, glove compartment covers, seats) Chairs, rear guards, etc.), or functional and structural parts (fuel tank, radiator water chamber, air filter cover, fan blades, etc.), the shadow of plastic parts can be seen everywhere. At present, 100kg plastic materials on modern cars replace the traditional metal materials that originally required 200-300kg, and the weight-reduction effect is very prominent, which is of great significance for saving energy and reducing greenhouse gas emissions. For example, the replacement of metal by automobile plastic intake manifold can reduce the quality by 40% to 60%, and the surface light clear flow resistance is small, which can improve engine performance and play a certain role in improving combustion efficiency, reducing fuel consumption, vibration and noise reduction. According to statistics, there are dozens of plastics for automobiles, and the average amount of plastics per vehicle has accounted for 5% to 10% of the weight of automobiles. With the development of lightweight vehicles and the expansion of automotive plastics, automotive plastics The consumption of bicycles will further increase in the future.
