Description

Technical Field

[0001] This utility model relates to an AC motor, and more particularly to an automatic coating device for an AC motor rotor, belonging to the field of motor processing technology. Background Technology

[0002] After the rotor core, magnets, rotor windings, and motor shaft of an AC motor are assembled, an insulating varnish needs to be applied to the outer surface of the rotor. This varnish is then heated to cure. The varnishing process is a crucial step in motor rotor manufacturing, directly impacting the motor's lifespan. Currently, rotor surface varnishing is typically achieved through manual spraying or brushing.

[0003] Manual spray painting typically involves operators using spray guns or atomizers to coat the rotor surface. During spraying, the insulating varnish is applied to the rotor surface in a mist form, and large amounts of paint mist can be harmful to human health. When the paint mist concentration is too high or air circulation is poor, it can also easily lead to safety accidents such as fires.

[0004] Manual painting typically involves operators using brushes to apply paint to the rotor surface. This method is labor-intensive, inefficient, and results in uneven paint thickness and poor consistency on the rotor surface. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic paint roller device for AC motor rotors that has high working efficiency, uniform and consistent paint thickness on the surface of AC motor rotors, and can avoid safety accidents such as fires and will not cause harm to the human body.

[0006] To solve the above-mentioned technical problems, this utility model adopts an automatic AC motor rotor painting device, including a first roller, a second roller, a roller drive mechanism, a paint box for holding paint, a paint box vertical lifting mechanism, and a frame. The first roller and the second roller are arranged horizontally and parallel to each other with a front-to-back gap. The left and right ends of the first roller are rotatably connected to the frame, and the left and right ends of the second roller are also rotatably connected to the frame. The roller drive mechanism includes a motor and a transmission mechanism. The first roller or the second roller is driven to rotate by the motor through the transmission mechanism. The AC motor rotor is located above the first roller and the second roller and positioned between them. The paint box is located below the first roller and the second roller. The paint box vertical lifting mechanism is mounted on the frame, and the paint box is driven to move up and down by the paint box vertical lifting mechanism.

[0007] In a preferred embodiment of the present invention, the frame includes at least two profiles with grooves. The left and right ends of the first roller are rotatably mounted on the first bearing seat, and the first bearing seat is slidably connected to the profile in the front-back direction and fixed by bolts. The left and right ends of the second roller are rotatably mounted on the second bearing seat, and the second bearing seat is slidably connected to the profile in the front-back direction and fixed by bolts.

[0008] In a preferred embodiment of this utility model, the transmission mechanism is a synchronous pulley and synchronous belt transmission mechanism, and the vertical lifting mechanism of the paint box is a manual or electric scissor-type lifting mechanism.

[0009] In a preferred embodiment of the present invention, the roller drive mechanism further includes a motor speed regulator, which is electrically connected to the controller of the motor.

[0010] In a preferred embodiment of this utility model, the outer circular walls of the first roller and the second roller are covered with a rubber sheet made of acrylic fiber and polyurethane.

[0011] By adopting the above structure, this utility model has the following beneficial effects:

[0012] When this invention is in operation, the paint box is raised to the bottom of the first and second rollers by a vertical lifting mechanism, preferably a manual or electric scissor-type lifting mechanism, so that the bottoms of the first and second rollers are immersed in the paint in the paint box. The motor is started, and the first or second roller is driven to rotate by the motor through a transmission mechanism, preferably a synchronous pulley and synchronous belt transmission mechanism. Preferably, the first roller is the driving roller and the second roller is the driven roller. When the AC motor rotor rolls between the first and second rollers, the paint is evenly transferred to the surface of the AC motor rotor, avoiding the problem of uneven thickness caused by manual painting and ensuring the consistency of the paint thickness on the rotor surface.

[0013] The distance between the first and second rollers of this invention is adjustable. By sliding the first and second bearing seats and fixing them with bolts, it can adapt to AC motor rotors of different sizes.

[0014] The paint box of this utility model is driven by a vertical lifting mechanism to move up and down, which can precisely control the amount of contact between the first roller and the second roller and the paint, and adapt to different paint application requirements.

[0015] This invention allows the speed of the first and second rollers to be adjusted by a motor speed regulator according to the diameter of the AC motor rotor. The larger the rotor diameter, the lower the roller speed, thus further optimizing the coating effect.

[0016] The outer circular walls of the first and second rollers of this invention are covered with rubber made of acrylic fiber and polyurethane, which not only improves the coating effect but also protects the rotor surface and extends the service life of the rollers.

[0017] This invention avoids the health hazards caused by paint mist diffusion during manual painting, such as inhalation of toxic substances and fire risks, while also reducing safety hazards in the work environment.

[0018] This invention replaces traditional manual spraying or brushing with an automatic roller painting device, significantly reducing operation time and improving painting efficiency. It solves the problems of low efficiency, poor uniformity, and numerous safety hazards associated with traditional painting methods, significantly improving the manufacturing process quality and production safety of motor rotors. Furthermore, it has a simple structure, is easy to implement, and is convenient for widespread application. Attached Figure Description

[0025] See Figures 1 to 5The diagram illustrates an automatic paint roller device with an AC motor rotor, comprising a first roller 1, a second roller 2, a roller drive mechanism 3, a paint container 4, a paint container vertical lifting mechanism 5, and a frame 6. The first roller 1 and second roller 2 are preferably cylindrical bodies with short shafts at both ends. The frame 6 is preferably a frame box structure made of steel plates or similar materials. The first roller 1 and second roller 2 are arranged horizontally and parallel to each other, with the left and right ends of the first roller 1 and the second roller 2 rotatably connected to the frame 6. The roller drive mechanism 3 includes a motor 3-1 and a transmission mechanism 3-2. The first roller 1 or the second roller 2 is driven to rotate by the motor 3-1 through the transmission mechanism 3-2. Figure 1 , 2 The first roller 1 shown is driven to rotate by the motor 3-1 through the transmission mechanism 3-2. The AC motor rotor 7 is located above the first roller 1 and the second roller 2 and placed between them. The paint box 4 is located below the first roller 1 and the second roller 2. The paint box vertical lifting mechanism 5 is installed on the frame 6. The paint box 4 is driven to move up and down by the paint box vertical lifting mechanism 5.

[0026] As a preferred embodiment of this utility model, such as Figure 3 As shown, the frame 6 includes at least two profiles 6-1 with sliding grooves 6a. The left and right ends of the first roller 1 are rotatably mounted on the first bearing seat 8, and the first bearing seat 8 is slidably connected to the profile 6-1 in the front-back direction and fixed by bolts. The left and right ends of the second roller 2 are rotatably mounted on the second bearing seat 9, and the second bearing seat 9 is slidably connected to the profile 6-1 in the front-back direction and fixed by bolts. In this invention, it is preferable to install sliders at the bottom of the first bearing seat 8 and the second bearing seat 9, so that the sliders slide within the sliding grooves 6a, thereby forming a slidable connection with the profile 6-1 in the front-back direction. The sliders are not shown in the figure.

[0027] In a preferred embodiment of this utility model, the transmission mechanism 3-2 is a synchronous pulley and synchronous belt transmission mechanism, such as... Figure 1 , 3 As shown, a synchronous pulley is installed at the output shaft end of motor 3-1 and the right end of the first roller 1. The transmission mechanism 3-2 can also be a coupling, and the output shaft of motor 3-1 is connected to the right end of the first roller 1 through the coupling. The vertical lifting mechanism 5 of the paint box is a conventional manual or electric scissor-type lifting mechanism. Of course, the vertical lifting mechanism 5 of the paint box can also adopt conventional mechanisms such as cylinders or linear motors.

[0028] In a preferred embodiment of the present invention, the roller drive mechanism 3 further includes a motor speed regulator 3-3, which is electrically connected to the controller of the motor 3-1.

[0029] In a preferred embodiment of the present invention, the outer circular walls of the first roller 1 and the second roller 2 are covered with rubber made of acrylic fiber and polyurethane.

[0030] When this utility model is in operation, see Figure 1 The paint box 4 is raised to the bottom of the first roller 1 and the second roller 2 by a manual or electric scissor-type lifting mechanism 5, and the bottom of the first roller 1 and the second roller 2 are immersed in the paint in the paint box. The motor 3-1 is started, and the first roller 1 is driven to rotate by the motor 3-1 through the synchronous pulley and synchronous belt transmission mechanism. The second roller is a passive roller. When the AC motor rotor 7 rolls between the first roller 1 and the second roller 2, the paint is evenly transferred to the surface of the AC motor rotor 7, avoiding the problem of uneven thickness caused by manual painting and ensuring the consistency of the paint thickness on the surface of the AC motor rotor 7.

[0031] After trial use, this utility model has a simple structure, uniform and consistent paint thickness on the surface of the AC motor rotor, high working efficiency, and avoids safety accidents such as fires, achieving good practical results.
