Description

technical field [0001] The invention belongs to the field of auto parts processing, and specifically discloses an auto casting painting device. Background technique [0002] Automobile painting is one of the important contents of automobile beauty. In the process of automobile manufacturing, for the sake of beauty and better protection of castings, many castings need to be painted. [0003] At present, there are two ways to spray paint on automobile castings: [0004] 1. Manual spraying, drying and drying after spraying, that is, spraying the castings with a hand-held paint spray gun, and then manually sending the painted castings to a flat place under the sun for drying. Not only is the labor intensity of the workers high, but also many substances volatilized by the paint are harmful to the human body. The drying condition also depends on the weather, and the drying time is uncontrolled. If you need to spray paint in batches, it is very time-consuming and laborious. [0...

Problems solved by technology

After the teaching work is completed, the robot can repeat the painting operation according to the fixed painting trajectory. This working method of the painting robot has high requirements on the positioning accuracy of the automotive castings. Once the position of the automotive castings is different from the situation when the robot is teaching , the spraying accuracy of the spraying robot will drop sharply, and even cause the spraying failure

However, when painting in batches, it is difficult to ensure the positioning accuracy of automotive castings
