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...

Examples

Embodiment 1

[0054] see figure 1 , the automobile body painting system provided in this embodiment is applied in the automobile painting booth. The automobile painting booth includes a coordinate generation area, a painting area and a detection area. 3 and the painting robot 4; the vehicle body transmission unit 1 is used to carry the vehicle body to be painted and move to the coordinate generation area, the painting area and the detection area in sequence according to the transmission signal; the visual sensing unit 2 is used to obtain the current position of the body to be painted in the coordinate generation area Position coordinates; the calculation unit 3 is used to generate a tracking coordinate system according to the current position coordinates, standard position coordinates and transmission signals; the painting robot 4 obtains a corrected spraying path based on the tracking coordinate system, and completes the painting of the vehicle body to be painted in the painting area.

Embodiment 2

[0069] see figure 2 , another embodiment of the present invention provides a kind of painting method of automobile body, comprises:

[0070] According to the transmission signal, the car body to be painted is moved to the coordinate generation area, the painting area and the detection area in sequence;

[0071] Obtain the current position coordinates of the body to be painted in the coordinate generation area;

[0072] generating a tracking coordinate system according to the current position coordinates, the standard position coordinates and the transmission signal;

[0073] The corrected spraying path is obtained based on the tracking coordinate system, and the painting of the vehicle body to be painted is completed in the painting area.

[0074] Compared with the prior art, the beneficial effect of the automobile body painting method provided by the embodiment of the present invention is the same as that of the automobile body painting system provided in the first embodim...
