As a key component of a car, because of its complex appearance, the domestic axle painting process mainly relies on manual work. In recent years, with the increase of production capacity and the improvement of quality standards, the shortcomings of unstable quality, low efficiency and poor environmental performance of manual work have been exposed, which has severely restricted the production of axles. How to improve the quality of axle spraying and production efficiency , To improve environmental performance has become an urgent problem for axle manufacturers to solve.
As the most advanced automatic spraying equipment at present, the spraying robot has a flexible wrist structure and precise control of the spraying process. It also has outstanding performance in terms of equipment environmental protection performance. It is a solution to the automatic It is an important equipment for spraying problems. Therefore, we have formulated a spraying robot solution for the axle painting line according to the characteristics and process of the axle spraying process.
The axle spraying robot system is used to spray the primer and topcoat of the automobile axle coating line. The axle primer is sprayed once, and the topcoat is sprayed twice. Three spraying workstations (primer spraying workstation, topcoat 1 spraying) can be set up. Workstation, topcoat 2 spraying workstation), each spraying workstation is equipped with a robot spraying station and a manual paint retouching station. Through the understanding of the production process of the axles, the axles flow from the 6 assembly lines to the painting line. The axle painting is divided into primer and topcoat. The primer is sprayed once, and the topcoat is sprayed twice, using wet-on-wet spraying. Craft. Each axle spraying station is equipped with 2 spraying robots, which are placed on both sides of the conveyor line. The robots are equipped with electrostatic air spray guns, which can automatically clean and change colors. After each robot spraying station, a manual touch-up station is set up. Because it is a mixed-flow production, in order to improve the automation and reliability of the axle painting system, the identification problem of the axle model must be solved. This system mainly uses the radio frequency identification system to solve the identification problem of multiple models of axles. The conveyor chain is a continuous chain, and the vehicle bridge needs to be painted during the walking process. The spraying robot needs to track the operation of the vehicle bridge. In order to solve the synchronization problem between the robot and the vehicle bridge, the system is equipped with a conveyor chain tracking system. In the later period, the axle spraying robot will also be continuously updated and transformed to keep up with the development trend of the axle industry.
