Description

technical field [0001] The invention relates to the technical field of spraying robot spraying processing, and more particularly, relates to an off-line simulation processing method and system for a spraying robot of a high-speed rail vehicle body. Background technique [0002] As intelligent equipment, spraying robots have obvious effects on improving spraying efficiency and spraying quality, and can effectively reduce labor costs, so they are widely used in modern manufacturing industries. [0003] However, the traditional spraying robot mainly adopts the "teaching-reproduction" method to complete the spraying operation. The quality of the spraying trajectory of the spray gun depends heavily on the worker's experience, and it is difficult to ensure the optimal spraying effect; the robot cannot be used in production during the teaching process. Moreover, the teaching period is long, which reduces the production efficiency of the robot. [0004] Domestic offline programming...

[0003] However, the traditional spraying robot mainly adopts the "teaching-reproduction" method to complete the spraying operation. The quality of the spraying trajectory of the spray gun depends heavily on the worker's experience, and it is difficult to ensure the optimal spraying effect; the robot cannot be used in production during the teaching process. And the teaching cycle is long, which reduces the production efficiency of the robot

[0004] The off-line programming and simulation system for spraying robots is still in the research stage in China, and there are no mature products on the market. The off-line programming systems proposed by many well-known universities are mostly for welding, cutting and other fields. Research on the automatic programming of spraying robots and other aspects; the spraying process is a relatively complex system, and there is currently no relatively complete offline programming system for spraying processing in China, and the spraying offline programming system still has a long way to go before it is practically applied
