Description

Technical Field

[0001] This invention relates to the field of motor manufacturing and processing technology, specifically to a motor stator processing equipment. Background Technology

[0002] The stator is an important component of motors such as generators and starters. It is a crucial part of the electric motor. The stator consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating (output) current.

[0003] The motor stator needs to be polished, usually using sandpaper. The ring-shaped sandpaper is tensioned by two rotating wheels. The rotation of the wheels will drive the sandpaper to grind and polish the motor stator. Because the sandpaper wears out quickly, it needs to be replaced frequently. The sandpaper is usually replaced manually. However, because the two rotating wheels need to be tensioned to keep the sandpaper in place, the two rotating wheels are relatively large. The ring-shaped sandpaper is relatively soft, making it difficult for a person to align and fit it onto the two rotating wheels. This results in a long time consumption and low efficiency when replacing the sandpaper. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a motor stator processing equipment.

[0005] One embodiment of the present invention provides a motor stator processing equipment, including: a machine base, a conveying mechanism, and a polishing mechanism;

The first rotating drive module is drivenly connected to the rotating wheel.

[0010] The sandpaper replacement assembly includes a guide, a first translation drive module, an ejector, and a second translation drive module. The guide is located on one side of the lifting seat and corresponds to the positions of the tension wheel and the rotating wheel. A spare piece of sandpaper is fitted on the guide. The first translation drive module is driven to the guide and is used to drive the guide to move closer to or away from the lifting seat. The ejector is arranged around the guide. The second translation drive module is driven to the ejector and is used to drive the ejector to move closer to or away from the lifting seat. When the ejector moves toward the lifting seat, it pushes the spare piece of sandpaper on the guide onto the tension wheel and the rotating wheel.

[0013] In some alternative embodiments, a mounting bracket is rotatably mounted on the machine base, the mounting bracket is located on one side of the lifting seat, and a plurality of sandpaper replacement components are mounted on the mounting bracket. After the mounting bracket is rotated, the guide of one of the sandpaper replacement components corresponds to the position of the tension wheel and the rotating wheel.

The drive wheel is provided with a plurality of elastic drive parts, which are arranged around the rotation axis of the drive wheel. The second rotary drive module is drivenly connected to the drive wheel. When the drive wheel rotates, it drives the stator of the motor on the conveying mechanism to rotate through the elastic drive parts.

[0017] In some alternative embodiments, the motor stator processing equipment also includes a coating mechanism;

[0018] The coating mechanism includes a lifting frame, a roller brush, and a second lifting drive module. The lifting frame is vertically and vertically disposed above the conveying mechanism. The lifting seat and the lifting base are arranged sequentially along the conveying direction of the conveying mechanism. The second lifting drive module is drivenly connected to the lifting frame.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] Please see Figure 1 One embodiment of the present invention provides a motor stator processing equipment, including: a machine base 10, a conveying mechanism 20 and a polishing mechanism 30.

[0038] The conveying mechanism 20 is mounted on the machine base 10 and is used to convey the motor stator 70; the polishing mechanism 30 is mounted on the machine base 10 and is used to polish the motor stator 70. The polishing mechanism 30 includes a sanding component 40 and a sandpaper replacement component 50.

[0039] Please see Figure 2 and Figure 3 The abrasive assembly 40 includes a lifting seat 41, a first lifting drive module 42, a tension wheel 43, a rotating wheel 44, sandpaper 45, and a first rotating drive module 46. The lifting seat 41 is vertically and vertically mounted above the conveying mechanism 20. The first lifting drive module 42 is drivenly connected to the lifting seat 41. The tension wheel 43 and the rotating wheel 44 are mounted on the lifting seat 41. The sandpaper 45 is arranged around the tension wheel 43 and the rotating wheel 44. The first rotating drive module 46 is drivenly connected to the rotating wheel 44.

[0040] After the motor stator 70 is moved to the lower part of the lifting seat 41 by the conveying mechanism 20, the first lifting drive module 42 drives the lifting seat 41 to descend until the sandpaper 45 abuts against the motor stator 70. Then the first rotation drive module 46 drives the rotating wheel 44 to rotate, thereby driving the sandpaper 45 to move at high speed around the tension wheel 43 and the rotating wheel 44, so as to polish the electrode stator with the sandpaper 45. After polishing is completed, the first lifting drive module 42 drives the lifting seat 41 to rise.

[0041] Please see Figure 4 and Figure 5 The sandpaper replacement assembly 50 includes a guide 51, a first translation drive module 54, an ejector 55, and a second translation drive module 56. The guide 51 is located on one side of the lifting seat 41 and corresponds to the positions of the tension wheel 43 and the rotating wheel 44. A spare piece of sandpaper 511 is fitted on the guide 51. The first translation drive module 54 is driven to the guide 51 and is used to drive the guide 51 to move closer to or away from the lifting seat 41. The ejector 55 is arranged around the guide 51. The second translation drive module 56 is driven to the ejector 55 and is used to drive the ejector 55 to move closer to or away from the lifting seat 41. When the ejector 55 moves toward the lifting seat 41, the ejector 55 pushes the spare piece of sandpaper 511 on the guide 51 onto the tension wheel 43 and the rotating wheel 44.

[0042] When the sandpaper 45 on the tensioning wheel 43 and the rotating wheel 44 needs to be replaced, the operator removes the sandpaper 45. The removal can be done by tearing or cutting the sandpaper 45, which is a simple operation. Then, the first translation drive module 54 drives the guide 51 to move towards the lifting seat 41 until the guide 51 is close to the tensioning wheel 43 and the rotating wheel 44, or until the guide 51 abuts against the tensioning wheel 43 and the rotating wheel 44. Then, the second translation drive module 56 drives the ejector 55 to move towards the lifting seat 41, so that the ejector 55 pushes the spare sandpaper 511 on the guide 51 onto the tensioning wheel 43 and the rotating wheel 44, thus replacing the sandpaper 45. Then, the first translation drive module 54 drives the guide 51 away from the lifting seat 41, and the second translation drive module 56 drives the ejector 55 away from the lifting seat 41. Then the staff can place the next spare sandpaper 511 on the guide 51. While the staff is placing the spare sandpaper 511, the abrasive assembly 40 can still polish the electrode stator, thereby avoiding affecting production efficiency.

[0043] In some optional embodiments, the guide member 51 includes a base 52 and two guide posts 53 disposed on the base 52. The two guide posts 53 are respectively arranged opposite to the tension wheel 43 and the rotating wheel 44. Spare sandpaper 511 is sleeved on the outside of the two guide posts 53. A first translation drive module 54 is drivenly connected to the base 52, and an ejector 55 is arranged around the two guide posts 53. When the sandpaper 45 on the tension wheel 43 and the rotating wheel 44 needs to be replaced, the first translation drive module 54 drives the guide member 51 to move towards the lifting seat 41 until the two guide posts 53 of the guide member 51 abut against the tension wheel 43 and the rotating wheel 44 respectively, thereby facilitating the movement of the spare sandpaper 511 on the guide posts 53 to the tension wheel 43 and the rotating wheel 44, and preventing the sandpaper 45 from getting stuck or falling off.

[0044] In some alternative embodiments, the diameter of the guide post 53 gradually decreases towards the tension wheel 43 or the rotating wheel 44, thereby facilitating the detachment of the spare sandpaper 511 from the guide post 53. Since the two guide posts 53, like the tension wheel 43 and the rotating wheel 44, also tension the spare sandpaper 511, the guide posts 53 are designed to gradually decrease in size to prevent the ejector 55 from having difficulty ejecting the spare sandpaper 511 smoothly, making it easier for the spare sandpaper 511 to detach from the guide posts 53. Additionally, this also makes it easier for workers to place the spare sandpaper 511 onto the two guide posts 53.

[0045] In some optional embodiments, a mounting bracket 11 is rotatably mounted on the machine base 10. The mounting bracket 11 is located on one side of the lifting seat 41. Multiple sandpaper replacement components 50 are mounted on the mounting bracket 11. After the mounting bracket 11 rotates, the guide 51 of one of the sandpaper replacement components 50 aligns with the tension wheel 43 and the rotating wheel 44. This ensures that the guide 51 of the sandpaper replacement component 50, after moving towards the lifting seat 41, can align with the tension wheel 43 and the rotating wheel 44. Then, the ejector 55 can push the spare sandpaper 511 onto the tension wheel 43 and the rotating wheel 44. Multiple sandpaper replacement components 50 can be placed on the mounting bracket 11. Switching between different sandpaper replacement components 50 is achieved by rotating the mounting bracket 11. Since each sandpaper replacement component 50 can store one spare sandpaper 511, more spare sandpaper 511 can be stored simultaneously. Workers can place more spare sandpaper 511 at once, saving time and effort. The mounting bracket 11 can be rotated by a motor.

[0046] In some alternative embodiments, both the tensioning wheel 43 and the rotating wheel 44 are provided with limiting grooves 47. The limiting grooves 47 of the tensioning wheel 43 are arranged around the rotation axis of the tensioning wheel 43, and the limiting grooves 47 of the rotating wheel 44 are arranged around the rotation axis of the rotating wheel 44. A portion of the sandpaper 45 is located within the limiting grooves 47. The limiting grooves 47 can restrict the sandpaper 45 on the tensioning wheel 43 and the rotating wheel 44, preventing the sandpaper 45 from falling off the tensioning wheel 43 and the rotating wheel 44.

[0047] In some alternative embodiments, a positioning wheel 48 is rotatably provided on the lifting seat 41. The positioning wheel 48 is located on one side of the sandpaper 45. After the lifting seat 41 is lowered, the sandpaper 45 and the positioning wheel 48 abut against both sides of the motor stator 70. The positioning wheel 48 helps to maintain the position of the motor stator 70, so that the sandpaper 45 can stably apply pressure to the motor stator 70.

[0048] In some optional embodiments, the motor stator processing equipment further includes a coating mechanism 60. The coating mechanism 60 includes a lifting frame 61, a roller brush 62, and a second lifting drive module 63. The lifting frame 61 is vertically and movably positioned above the conveying mechanism 20. Lifting seats 41 and 42 are arranged sequentially along the conveying direction of the conveying mechanism 20. The second lifting drive module 63 is driven to connect with the lifting frame 61, and the roller brush 62 is rotatably mounted on the lifting frame 61. After the motor stator 70 moves below the lifting frame 61 under the transmission of the conveying mechanism 20, the second lifting drive module 63 drives the lifting frame 61 to descend until the roller brush 62 abuts against the motor stator 70. The roller brush 62 then coats the motor stator 70 with a liquid. After coating, the second lifting drive module 63 drives the lifting frame 61 to rise. The liquid coated on the motor stator 70 by the roller brush 62 can be a light gold solution or other liquid used for cleaning and rust prevention, thereby protecting the motor stator 70.

[0049] In some optional embodiments, the coating mechanism 60 further includes a hopper 64 and a third translation drive module 65. The hopper 64 is disposed on one side of the lifting frame 61, and the third translation drive module 65 is driven to move the hopper 64 to below or away from the lifting frame 61. When the roller brush 62 is low on material, the second lifting drive module 63 drives the lifting frame 61 to rise, and then the hopper 64 moves to below the lifting frame 61 under the drive of the third translation drive module 65. The second lifting drive module 63 then drives the lifting frame 61 to descend, causing the roller brush 62 to extend into the liquid in the hopper 64, thus replenishing the roller brush 62. The second lifting drive module 63 then drives the lifting frame 61 to rise again, and the third translation drive module 65 drives the hopper 64 away from the lifting frame 61 to avoid it. The hopper 64 is equipped with two feed inlets, which are connected to the same feed box. This allows the liquid in the hopper 64 to automatically flow back into the feed box when there is too much liquid, thus preventing the hopper 64 from becoming too full.

[0050] Please see Figures 6 to 8 In some optional embodiments, the machine base 10 is provided with two stator drive mechanisms 12. The stator drive mechanism 12 includes a drive wheel 13 and a second rotary drive module 14. The drive wheel 13 is rotatably disposed at the bottom of the conveying mechanism 20. The drive wheels 13 of the two stator drive mechanisms 12 are respectively located below the lifting seat 41 and the lifting frame 61. The drive wheel 13 is provided with a plurality of elastic drive parts 15, which are arranged around the rotation axis of the drive wheel 13. The second rotary drive module 14 is drivenly connected to the drive wheel 13. When the drive wheel 13 rotates, it drives the motor stator 70 on the conveying mechanism 20 to rotate through the elastic drive parts 15.

[0051] During polishing of the motor stator 70, the drive wheel 13 located below the lifting seat 41 rotates under the drive of the second rotary drive module 14. The drive wheel 13 drives the motor stator 70 to rotate through the friction of the elastic drive part 15, so that different positions of the motor stator 70 can be polished evenly. Because the elastic drive part 15 is elastic, it can generate elastic deformation when pressing the motor stator 70, thereby driving the motor stator 70 to rotate without damaging it. Since the sandpaper 45 is pressed on the motor stator 70 near the top, and the elastic drive part 15 abuts against the motor stator 70 near the bottom, it can clamp the motor stator 70. In this embodiment, the sandpaper 45 and the positioning wheel 48 are pressed on the two sides of the motor stator 70 near the top, respectively, and together with the elastic drive part 15, three-point positioning can be achieved, making the position of the motor stator 70 stable and not easy to shift.

[0052] Similarly, when the roller brush 62 coats the motor stator 70 with liquid, the drive wheel 13 located below the lifting frame 61 rotates under the drive of the second rotary drive module 14. The drive wheel 13 drives the motor stator 70 to rotate through the friction of the elastic drive part 15 against the motor stator 70, so that different positions of the motor stator 70 can be uniformly coated with liquid, preventing excessive liquid dripping. Because the elastic drive part 15 is elastic, it can produce elastic deformation when the motor stator 70 is squeezed, thereby driving the motor stator 70 to rotate without damaging it. Since the roller brush 62 presses against the motor stator 70 near the top, and the elastic drive part 15 abuts against the motor stator 70 near the bottom, it can clamp the motor stator 70. Of course, the method of uniformly coating the motor stator 70 is not limited to this. Those skilled in the art can also choose other suitable methods according to the teachings of this invention. For example, a drive motor can be provided on the lifting frame 61, and the drive motor can drive the roller brush 62 to rotate, and the roller brush 62 can also drive the motor stator 70 to rotate.

[0053] The specific structures of the first lifting drive module 42 and the second lifting drive module 63 can be designed according to actual needs. For example, the first lifting drive module 42 and the second lifting drive module 63 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly. In this embodiment, the first lifting drive module 42 and the second lifting drive module 63 are driven by cylinders.

[0054] The specific structures of the first translation drive module 54, the second translation drive module 56, and the third translation drive module 65 can be designed according to actual needs. For example, the first translation drive module 54, the second translation drive module 56, and the third translation drive module 65 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly. In this embodiment, the first translation drive module 54, the second translation drive module 56, and the third translation drive module 65 adopt a drive cylinder.

[0055] The specific structure of the first rotary drive module 46 and the second rotary drive module 14 can be designed according to actual needs. For example, the first rotary drive module 46 and the second rotary drive module 14 can be driven by a drive motor.

[0056] The specific structure of the conveying mechanism 20 can be designed according to actual needs. For example, the conveying mechanism 20 can be a mesh belt conveying mechanism 20, a roller conveying mechanism 20, a chain plate conveying mechanism 20, and a belt conveying mechanism 20. In this embodiment, the conveying mechanism 20 includes multiple material conveying racks, two transmission chains, and a drive motor. The two transmission chains are respectively connected to both sides of the material conveying racks. The multiple material conveying racks are arranged sequentially along the transmission chains. There is a through groove in the middle of the material conveying rack. Two parallel rollers are arranged on both sides of the through groove. The middle part of the motor stator 70 is arranged in the middle position of the through groove. The two sides of the motor stator 70 are respectively arranged between the two rollers, so that the motor stator 70 can rotate on the material conveying rack. The elastic drive part 15 of the drive wheel 13 can extend into the through groove and abut against the motor stator 70. The drive motor is connected to the transmission chain and drives the transmission chain to move.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
