Gold lacquer coating equipment for end surface of cast-aluminum rotor of plastic package motor

Abstract

The invention discloses gold lacquer coating equipment for an end surface of a cast-aluminum rotor of a plastic package motor. The gold lacquer coating equipment comprises a rack, a coating box, a drying box, a gold lacquer supply box, a hot fan, toothed plates, bearing devices and gears, wherein placement table devices are arranged on a conveying belt and are used for placing the cast-aluminum rotor, each placement table device comprises the bearing device, the gear, an installation seat and a rotation shaft, electric telescopic rods are symmetrically and fixedly arranged at the top of an inner cavity of the coating box, sponges are arranged at the bottoms of the two electric telescopic rods, a plurality of brushes are arranged at the bottoms of the sponges, a gold lacquer transmission pipe communicates with the bottom of an inner cavity of the gold lacquer supply box, the bottom of the gold lacquer transmission pipe is connected with the two sponges via two liquid transmission hoses,and the toothed plates are fixedly arranged at inner walls of a front side plate and a rear side plate of the coating box. By the gold lacquer coating equipment, gold lacquer on the brushes can be uniformly coated on the cast-aluminum rotor, uniform coating is achieved, the drying of the cast-aluminum rotor is convenient, the labor and the material are greatly reduced, and the gold lacquer coating equipment is suitable for promotion and application.

Description

technical field [0001] The invention relates to motor production equipment, in particular to a device for smearing the end face of a cast aluminum rotor of a plastic-encapsulated motor with light gold water. Background technique [0002] The plastic-encapsulated motor uses plastic packaging technology to package the stator core and winding of the motor with engineering plastics, which can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. This kind of micro motor is used in household appliances such as vacuum cleaners, range hoods, air conditioners, washing machines and instrument fans. There will be cast aluminum end rings at both ends of the rotor of the plastic-encapsulated motor. This cast aluminum end ring has three functions. First, it is used as the terminal wire of the rotor conductor, also known as the short-circuit ring, to connect the rotor winding; second, it also serves as A simple fan acts as a heat sink; ...

AI Technical Summary

Problems solved by technology

[0003] The end surface of the cast aluminum rotor will be coated with light gold water treatment after casting aluminum. The existing coating process is to apply one by one by manual hand-held brushes. The efficiency of this coating method is very low, and the existing This application method is very easy to apply the light gold water to the end ring or to the hands, which wastes a lot of light gold water and causes a lot of waste
