Vehicle body paint spraying system and method

Abstract

The invention discloses a vehicle body paint spraying system and method, relates to the technical field of vehicle manufacturing and aims at solving the quality problem that less paint, sagging and the like on vehicle body paint finish caused by offset of the position of a vehicle body to be painted in the vehicle body paint spraying process in the prior art. The system comprises a vehicle body transferring unit, a vision sensing unit, a calculation unit and a paint spraying robot which are sequentially connected with one another; the vehicle body transferring unit is used for bearing the vehicle body to be painted to sequentially move to a coordinate generation region, a paint spraying region and a detection region according to a transferring signal; the vision sensing unit is used for acquiring a current position coordinate of the vehicle body to be painted in the coordinate generation region; the calculation unit is used for generating a track coordinate system according to the current position coordinate, a standard position coordinate and the transferring signal; and paint spraying robot obtains a corrected spraying path based on the track coordinate system and finishes paintspraying of the vehicle body to be painted in the paint spraying region. The vehicle body paint spraying system provided by the invention is used for a vehicle paint spraying booth.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile body painting system and method. Background technique [0002] With the improvement of people's living standards, car consumption has entered the homes of ordinary people. For automobile manufacturing, body painting is an important process in the production of complete vehicles. In the existing body painting production line, the conveyor chain is usually used to transport the body to the painting area of ​​the painting robot, so that the body Driven by the conveyor chain, it moves correspondingly, and then the spraying robot completes the spraying of various parts of the car body according to the preset program. [0003] However, in the process of conveying the car body by the conveyor chain, the movement of the conveyor chain is usually caused by mechanical stop and other reasons, which will cause the conveyed car body to deviate from the preset s...
