[0002] The motor rotor, that is, the rotating part in the motor, is used to realize the conversion between electrical energy and mechanical energy. As a key component in the motor, it carries important functions and roles. When processing the motor rotor, in order to prevent the electronic rotor from corrosion and oxidation, the motor rotor surface after cutting will be evenly sprayed with protective liquid. At the same time, the motor rotor after spraying needs to be naturally dried or dried.

[0003] During the process of spraying and coating the rotor, since the rotor is in a ring-shaped state, it is easy to roll. In order to ensure the coating effect, the rotor itself needs to be limited. In order to overcome the above-mentioned defects, prior art 1 (publication number: CN112691827A, Chinese patent with publication date of 2021-04-23) is a ferrite rotor surface treatment device for motor processing, which belongs to the field of motor processing technology. A ferrite rotor surface treatment device for motor processing includes a moving component, an adjusting component, a rotating component, a fixed component, a lifting component, a drying component, a sprayer and a gantry.

Through the cooperation between the above components, the motor rotor can be automatically sprayed and dried, and the spraying effect is better.

[0004] There is also prior art 2 (publication number: CN106984469A, Chinese patent with publication date of 2017-07-28) a motor rotor spray paint room, in which the water collecting trough and the water retaining trough are arranged in parallel in the room body, and the lower end of the water retaining trough is placed in the inner cavity of the water collecting trough, the liquid inlet end of the circulating pump extends into the water collecting trough, the liquid outlet end of the circulating pump is connected with the water spray pipe, a plurality of water spray heads are arranged on the water spray pipe, an exhaust pipe is arranged at the top of the room body, and the exhaust pipe is connected with the inner cavity of the water retaining trough, and an exhaust fan is arranged in the exhaust pipe; a supporting bottom plate is arranged in the room body, two supporting uprights are fixed on the supporting bottom plate in parallel to each other, two turntables are respectively rotatably connected to the two supporting uprights, and the two turntables are fixedly connected by a connecting shaft, and a plurality of fixing buckles are fixed on the outer circumferential wall of each turntable. The present invention can support multiple rotors at one time, so that the spraying efficiency is improved; the paint mist generated during the painting process is filtered by water before entering the exhaust pipe, and then is adsorbed and filtered again by the activated carbon in the exhaust pipe, thereby reducing the harmful substances entering the atmosphere.

[0005] And prior art 3 (publication number: CN110252567B, Chinese patent with publication date of 2020-12-08) A rotor painting and dynamic balancing processing line, including a paint spraying room and a drying room, a guide rail is connected between the paint spraying room and the drying room, a placement plate for placing the rotor is arranged above the guide rail, the placement plate is connected to the guide rail by sliding through the guide rail roller, the direction in which the placement plate moves from the paint spraying room to the drying room along the guide rail through the guide rail roller is the normal direction, a motor for driving the guide rail roller to rotate is arranged on the placement plate, and a limit assembly for limiting the position of the placement plate is arranged between the placement plate and the guide rail. The rotor to be painted is placed on the placement plate, and then the motor is driven so that the guide rail roller drives the placement plate to move along the guide rail into the paint spraying room for painting. After the painting is completed, the motor is driven so that the placement plate moves along the guide rail into the drying room to dry the rotor. After the paint on the outer wall of the rotor is dried, the placement plate moves along the guide rail to the next processing link. The present invention has the effect of improving work efficiency.

[0006] Although the existing technologies 1, 2 and 3 can be used to spray paint and prevent rust on the rotor, the rotor cannot be quickly dried after the painting is completed. During the storage and placement of the rotor, the undried paint may become sticky, thereby damaging the sprayed outer layer and affecting subsequent use.
