Description

Technical Field

[0001] This invention relates to the field of rotor technology, and in particular to a rotor coating device. Background Technology

[0002] The rotor and stator together form a motor. When the motor is powered on, it generates an electromagnetic field. The electromagnetic induction between the stator and rotor causes the rotor to rotate, thus driving other equipment to work. After the rotor is processed, its surface needs to be coated with insulating and anti-rust paint. Some manufacturers manually brush the paint onto the surface of the motor rotor. This method is labor-intensive, cannot guarantee that the insulating paint is evenly applied to the rotor surface, and has low work efficiency. Other manufacturers place the rotor on a track and set up a paint dripping device above the track. As the rotor rotates on the track, the paint dripping device drips paint onto the rotor, so that the surface of the rotor can be coated with paint. This method improves efficiency compared to manual painting. However, due to uneven paint dripping or the rotor rotation speed being difficult to be uniform, the anti-rust paint on the rotor surface is also uneven. Summary of the Invention

[0022] Reference Figure 1 and Figure 2The rotor coating device of this invention includes a frame 10 and a clamping and rotating mechanism mounted on the frame 10. The frame 10 is provided with a coating groove 11 and a guide rail 12 mounted on the side of the coating groove 11. The coating groove 11 is filled with anti-rust paint, and the rotor can roll along the guide rail 12. The clamping and rotating mechanism includes a support frame 20, a clamping part for clamping the rotor shaft, and a drive assembly capable of driving the clamping part to lift, translate, open, close, and rotate. The clamping part and the drive assembly are respectively mounted on the support frame 20. The drive assembly and the clamping part are connected. The connection is as follows: the drive assembly drives the clamping part to move horizontally to the side of the rotor, then drives the clamping part to close to clamp the rotor shaft, then drives the clamping part to move horizontally above the paint roller trough 11, then drives the clamping part to descend so that the rotor surface comes into contact with the anti-rust paint, then drives the clamping part to rotate at a constant speed so that the rotor surface is evenly coated with anti-rust paint, and finally drives the clamping part to rise sequentially, move horizontally to the guide rail 12, and release the rotor shaft. The rotor that has completed the paint roller coating is placed on the guide rail 12 to facilitate the next processing procedure. The paint roller coating is uniform and the processing efficiency is improved.

[0023] In some embodiments, the guide track 12 is inclined downward in a direction away from the paint roller trough 11, so that the rotor that has finished painting can roll along the guide track to the next process.

[0024] In some embodiments, the guide rail 12 is connected to the paint roller trough 11, which facilitates the clamping part to place the rotor that has completed the paint roller onto the guide rail 12 nearby, thereby improving efficiency.

[0025] In some embodiments, the driving assembly includes a translation assembly, which includes a first motor 21 mounted on the support frame 20 and a first lead screw connected to the motor shaft of the first motor 21. The first lead screw includes a first screw rod 211 and a first nut 212 sleeved on the first screw rod 211. The first screw rod 211 is horizontally positioned, and the first nut 212 is connected to the clamping part. When the first motor 21 is started, the first screw rod 211 rotates with the motor shaft, thereby driving the first nut 212 to translate, realizing the translation of the clamping part. The forward and reverse rotation of the first motor corresponds to different translation directions, thereby enabling the clamping part to reciprocate and translate. The structure is simple and easy to implement.

[0026] In some embodiments, the translation assembly further includes a drive wheel 213, a driven wheel 214 disposed on the side of the support frame 20, and a conveyor belt 215 connected to the drive wheel 213 and the driven wheel 214 respectively. The motor shaft of the first motor 21 is connected to the drive wheel 213, and the driven wheel 214 is connected to the first screw 211. The rotation of the first motor 21 is transmitted to the first screw 211 through the drive wheel 213, the driven wheel 214 and the conveyor belt 215, avoiding the direct connection between the first screw 211 and the motor shaft, and reducing the failure rate of the first screw 211.

[0027] In some embodiments, the drive assembly further includes a lifting assembly, which includes a second motor 22 mounted on the support frame 20 and a second lead screw connected to the motor shaft of the second motor 22. The second lead screw includes a second screw 221 and a second nut 222 sleeved on the second screw 221. The second screw 221 is vertically arranged, and the second nut 222 is connected to the clamping part, thereby driving the clamping part to move up and down in the vertical direction. The structure is simple and easy to implement.

[0028] In some embodiments, the drive assembly further includes a third motor 23, and the clamping part includes a gripper 24 and a cylinder 25 connected to the gripper 24. The cylinder 25 is located between the gripper 24 and the third motor 23. The motor shaft of the third motor 23 is connected to the cylinder 25 to drive the cylinder 25 to rotate and drive the gripper 24 to rotate. An external drive device is electrically connected to the cylinder 25 to control the cylinder to open and close. First, the cylinder 25 operates to control the gripper 24 to close to grip the rotor shaft. Then, the third motor 23 operates to make the gripper 24 rotate to achieve rotor coating. Then, the cylinder 25 operates to control the gripper 24 to release so that the rotor rolls along the guide track 11.

[0029] In some embodiments, the clamping part includes a horizontally arranged first connecting part 26 and a vertically arranged second connecting part 27. A first nut 212 is connected to the first connecting part 26, and a second nut 222 is connected to the second connecting part 27. A second motor 22 is arranged above the first connecting part 26, and a first through hole is provided on the first connecting part 26. The motor shaft of the second motor 22 passes through the first through hole and is connected to the second screw 221. The structure is simple and facilitates the vertical arrangement of the second motor, enabling the clamping part to move in both horizontal and vertical directions.

[0030] In some embodiments, the third motor 23, the gripper 24, and the cylinder 25 are respectively connected to the second connecting part 27, and the third motor 23 is located on the back of the second connecting part 27, while the gripper 24 and the cylinder 25 are located on the front of the second connecting part 27. The second connecting part 27 is provided with a second through hole, and the motor shaft of the third motor 23 passes through the second through hole and is connected to the cylinder 25. The structure is compact and easy to implement.
