Due to workspace limitations, extended working hours, and low efficiency, there is a significant impact on production progress.

(2) Paints containing heavy metals, radioactive substances, and toxic organic solvents pose significant health risks to spray painters in poor working conditions. Therefore, the adoption of robotic spray systems that can replace manual spraying is a great solution to address these drawbacks. However, the existing general-purpose spray robots on the market cannot meet the specific requirements for spraying these special parts and coatings. Consequently, a dedicated robotic spray system must be designed to cater to the complex pipeline and characteristics of the coatings.

(3) The quality of the powder coating is difficult to control due to the lack of mixing and circulation devices, which leads to significant changes in the viscosity and concentration of the paint during the spraying process. Moreover, the spraying distance and speed are also hard to control, often resulting in excessive thickness errors and the need for rework, or even failing to meet quality standards.
