Electrostatic rotatine bell robotic spraying is an advanced coating process that combines electrostatic spraying technology with robot automation control. It is mainly used for efficient spraying of workpieces in fields such as automobiles, furniture, and hardware. The core equipment is an electrostatic rotary cup spray gun, which atomizes the coating into charged particles and uniformly adsorbs them onto the surface of the workpiece through high-speed rotation (up to 25000 rpm under no-load and 30000-60000 rpm under load) combined with a high-voltage electrostatic field (-50~-120 kV)
