[0002] In the process of automobile manufacturing and maintenance, the spraying of auto parts is a crucial link. Most of the existing auto parts spraying devices have many shortcomings. Traditional spraying devices can usually only spray from a single angle. For auto parts with complex shapes, it is difficult to achieve full coverage, which can easily lead to uneven spraying, too thick or too thin areas, and even dead angles. In addition, the operating efficiency of existing devices is low. During the spraying process, the position of the parts and the angle of the spray gun need to be adjusted frequently, which takes a lot of time. Another way is to use a robotic arm. Although the multi-angle spraying of the robotic arm has improved some of the problems of traditional multi-angle spraying to a certain extent, the cost of industrial robotic arms for high-precision auto parts spraying is very high. For some small auto parts manufacturers or repair shops, the equipment cost is a huge burden. At the same time, the internal structure of the robotic arm is complex, including multiple joints, motors, sensors, etc. Once a fault occurs, diagnosis and repair are difficult. For example, if the joints of the robotic arm are worn or malfunction, professional technicians are needed to disassemble, inspect and replace parts. The replacement cost of the robotic arm's vulnerable parts, such as the nozzle and joint seals, is high. These parts are usually specially designed for the robotic arm, have poor versatility, and are more expensive than parts of ordinary spraying equipment. Summary of the invention
