[0002] At present, the electrostatic powder spraying process is widely used at home and abroad. Because iron bracket products themselves have many angles and relatively complex shapes, the existing spraying process is difficult to achieve efficient automatic spraying, and cannot fully realize automatic unmanned spraying. Manual assistance is required to spray the workpiece with powder, which increases the manufacturing cost and the unstable quality of the surface coating, thus affecting efficiency, uneven surface spraying, and high production costs.

[0003] The traditional spraying assembly line uses a spray gun to carry static electricity to the powder and spray it onto the surface of the workpiece. Due to the complex shape of the workpiece and the obstruction of the static electricity powder at the dead corners, the spray gun can only spray from both sides, so the thickness of the static electricity powder sprayed on the workpiece surface is uneven, which greatly affects the surface quality.
