Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic coating machines, in particular to an electrostatic coating machine for motor manufacturing. Background Art

[0002] Electrostatic spraying is an advanced coating method that utilizes the principles of electrostatics. This technology generates an electrostatic field by applying a high voltage direct current (DC) between a grounded workpiece and the spray gun. When negatively charged paint particles are sprayed into this field, they are affected by the electric force, causing them to collide with each other and adhere evenly to the workpiece surface. This field also applies to any paint particles scattered near the workpiece, ensuring perfect coverage of all surfaces, including complex geometries and small surface areas.

[0003] Electrostatic spraying technology can quickly and accurately spray every detail of the workpiece, improving production efficiency. The spraying effect is superior to traditional spraying processes in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., which helps to produce high-quality products. Although the initial equipment investment may be high, in the long run, electrostatic spraying technology is cost-effective because it can reduce paint waste, reduce labor costs and improve product qualification rate. This technology helps to reduce the emission of volatile organic compounds (VOCs), which meets the environmental protection requirements of modern industry.

[0004] Electrostatic coating machines for motor manufacturing are designed based on the principles and characteristics of electrostatic spraying technology. They are widely used to coat slot insulation in various miniature motor rotors, such as those found in automobiles, motorcycles, mopeds, toys, and household appliances. Using electrostatic spraying technology, these machines evenly coat the rotor surface with insulating powder, forming a high-quality insulation layer that improves motor performance and reliability.

[0005] Existing electrostatic coating machines used in motor manufacturing process the motor rotor by fixing the rotor on a rotating shaft and placing the two ends of the rotating shaft on two conveyor rollers, which drive the rotor to rotate forward inside the coating machine. However, during the coating process, coating powder will also adhere to the surface of the conveyor roller, increasing the friction between the conveyor roller and the rotating shaft, resulting in the conveyor roller's rotation on the rotating shaft being unstable, and the rotating shaft cannot truly rotate at a uniform speed inside the coating machine.
