Description

Technical Field

[0001] The invention relates to the technical field of automatic spraying of motor rotors, in particular to an automatic spraying device for motor rotors. Background Art

[0002] In the manufacturing process of motor rotors, spraying insulating coating is an important step, which helps to protect the iron core of the motor rotor from damage by current, moisture and other environmental factors. At the same time, the iron core on the rotor is one of the core structures in the motor rotor. Often, when the rotor is sprayed, the iron core has been installed on the rotor for synchronous spraying of insulating coating. At present, in the process of automatic spraying of motor rotors, electrostatic spraying of insulating paint is adopted, and the motor rotor is conveyed to the spraying equipment along with two advancing screws to spray the insulating paint. In order to make the sprayed paint adhere to the motor rotor more stably, the spraying equipment is provided with a primary heating mechanism and a secondary heating mechanism to heat the sprayed insulating paint so that the paint particles can adhere to the surface of the rotor more stably. However, before heating, in order to prevent excessive application of insulating paint and to ensure that the coating is more uniform and smooth, a nozzle is used to spray the rotor, and then a scraper is used to scrape the paint on the surface of the rotor core. However, in the process of multiple scrapers scraping the cores on multiple rotors in turn, more insulating paint is easily adhered to the scraper for a long time, which not only easily causes the paint on the scraper to adhere to the surface of the rotor core on the rotor, but also fails to fully scrape off the excess coating on the surface of the rotor core, further affecting the spraying effect of the motor rotor.
