[0002] In the automobile painting line, intelligent spraying equipment is the key equipment to achieve automated and precise painting.

[0003] Traditional spraying equipment often only includes a robot arm and a nozzle. The robot arm is responsible for moving the nozzle to the specified position, and the nozzle is responsible for spraying the paint. However, in practical applications, this simple structure has some problems. When the nozzle is repainting a specific part of the car, if there are no proper protective measures, it may spray to the area that does not need to be sprayed, resulting in a decrease in the quality of the coating. Not only will it waste spraying materials, but it is also easy to cause the part next to the paint to be oversprayed, thus affecting the overall appearance. Therefore, an intelligent spraying equipment for an automobile painting line is proposed. Utility Model Content
