Description

Technical Field

[0001] This invention relates to the field of paint dripping machine technology, and in particular to an angle grinder motor rotor paint dripping machine and its usage method. Background Technology

[0002] In the manufacturing process of angle grinder motors, the rotor, as the core power component, directly determines the motor's operational stability and service life through its insulation performance. To improve the rotor's insulation level and reduce energy loss during operation, the industry commonly employs a drip-painting process to treat the rotor windings. By precisely dripping insulating varnish and following a subsequent curing process, a uniform and dense insulating coating is formed on the winding surface, thereby isolating the windings from moisture, dust, and other impurities, while also enhancing the windings' mechanical strength.

[0003] Currently, the coating equipment used for angle grinder motor rotors on the market has developed relatively mature technical solutions in the core coating action control. However, there is still a significant lack of automation in the rotor loading and unloading process. Most existing equipment uses a manual loading and unloading mode. Before the coating operation starts, the operator must manually grab the rotor workpiece, accurately align it with the equipment's positioning fixture, and complete the installation and fixation using bolts, clips, etc., to ensure the rotor maintains a stable rotational posture during the coating process. After the coating process is completed, the operator must first remove the fixing structure and then manually remove the coated rotor from the fixture and transfer it to the subsequent drying or inspection station. This manual loading and unloading method first and foremost hinders production efficiency. The loading and unloading process consumes a significant amount of the operator's time, especially in batch production scenarios, where the cycle speed of manual operation is far lower than that of automatic coating, creating a significant production bottleneck and failing to meet the high-efficiency operation requirements of modern production lines. Secondly, the consistency of manual operation is poor. Different operators may vary in the tightening force and positioning accuracy during rotor installation, potentially causing slight displacement or shaking of the rotor during the paint dripping process. This results in uneven paint dripping, affecting the consistency of the rotor's insulation performance and increasing the product defect rate. Furthermore, improper manual handling of the rotor can damage the incompletely cured insulating paint coating, further reducing product quality. In addition, from the perspective of production safety and labor costs, operators need to repeatedly perform mechanical actions such as picking up, placing, and fixing the equipment for extended periods. This is not only physically demanding but also poses a safety hazard of being scratched by moving parts. Moreover, with the continuous rise in labor costs, the company's production and operating costs also increase. Therefore, this invention proposes a paint dripping machine for an angle grinder motor rotor and its usage method. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the background art where the loading and unloading of angle grinders relies on manual labor, resulting in low production efficiency, poor operational consistency leading to high product defect rates, high labor intensity and safety hazards, and increased enterprise operating costs. The invention proposes an angle grinder motor rotor paint dripping machine and its usage method.

[0005] On one hand, the present invention proposes a paint-dripping machine for an angle grinder motor rotor, including a worktable and support legs for supporting it, a moving mechanism mounted on the worktable for driving the rotor to move; a self-rotating component mounted on the worktable for driving the rotor to rotate; a connecting mechanism mounted on the side of the moving mechanism away from the self-rotating component for fixing the rotor to the moving mechanism; loading and unloading mechanisms located on both sides of the worktable for automatically loading and unloading the rotor; a connecting component mounted on the side of the loading and unloading mechanism closer to the moving mechanism for driving the connecting mechanism to clamp the rotor; and a paint-dripping component mounted on the worktable for dripping paint onto the rotating rotor.

[0009] Optionally, the loading and unloading mechanism includes a mounting plate fixedly connected to the side of the support leg. A first push rod motor is mounted on the side of the mounting plate.

[0010] Optionally, the connecting assembly includes a synchronization frame fixedly connected to the bottom of the placement frame.

The second spring is located between the placement frame and the fourth gear. A limit plate is fixedly connected to the end of the fixed shaft away from the placement frame.

[0011] Optionally, a limiting mechanism is also included, located on the side of the moving mechanism away from the loading and unloading mechanism. The limiting mechanism is used to prevent the synchronous rod from rotating when the second gear rotates to lock the rotor. The limiting mechanism includes a mounting frame fixedly connected to the support leg. A third push rod motor is mounted on the side of the mounting frame. A lifting plate is fixedly connected to the output end of the third push rod motor. Multiple sets of limiting rods are slidably connected in the lifting plate.

A third spring is sleeved on the outer ring of the limiting rod. The third spring is located between the lifting plate and the top plate. A sliding sleeve is slidably sleeved on the limiting rod. The sliding sleeve is fixedly connected to the mounting frame.

[0012] Optionally, the paint dripping assembly includes multiple sets of paint dripping cylinders disposed above the workbench. The multiple sets of paint dripping cylinders are distributed in an equidistant array. The bottom of each paint dripping cylinder is provided with multiple sets of paint outlets. The positions of the paint outlets at the bottom of adjacent sets of paint dripping cylinders are staggered. A fixing frame is fixedly connected to each paint dripping cylinder. A central frame installed on the top of the workbench is disposed below the multiple sets of paint dripping cylinders. A collection box installed on the bottom of the workbench is disposed at the position of the central frame. A through hole is opened at the corresponding position of the workbench and the collection box. The through hole is located inside the central frame. An output pump is installed on the side of the collection box. The output end of the output pump is connected to the multiple sets of paint dripping cylinders through a pipe.

[0013] Optionally, it also includes a protective plate installed on the top of the workbench. The protective plate is L-shaped, and multiple sets of the fixing brackets are fixedly connected to the protective plate. A drying box is fixedly connected to the protective plate. The moving mechanism and the self-rotating component are both installed in the drying box, and a drying module is provided in the drying box.

[0014] On the other hand, this invention proposes a method for using an angle grinder motor rotor paint spraying machine, comprising the following steps:

[0015] Step 1: The robotic arm places the angle grinder motor rotor to be dripped with paint into the placement frame of the loading and unloading mechanism on one side of the worktable, and the shafts at both ends of the rotor are inserted into the arc grooves at the top of the placement frame.

[0016] Step 2: The first push rod motor starts, pushing the moving plate along the first guide rail, causing one end of the rotor to align with the connecting cylinder of the connecting mechanism in the moving mechanism;

[0017] Step 3: The third servo motor starts and drives the third gear to rotate. The third gear meshes with and drives the fourth gear to rotate, achieving stable meshing with the second gear.

[0018] Step 4: The output end of the third push rod motor pushes the lifting plate to rise. The lifting plate drives the top plate to rise through the third spring until the rack at the top of the top plate meshes with the first gear. Then, the second gear rotates under the drive of the fourth gear, causing the threaded sleeve to move along the thread of the connecting cylinder. The sleeve drives multiple sets of inclined blocks to move synchronously. The inclined blocks squeeze the inclined groove and push the pressure block to gather towards the center of the connecting cylinder until one end of the rotor is clamped.

[0019] Step 5: The second push rod motor starts and drives the placement frame to descend along the second guide rail. After the placement frame is separated from the rotor, the first push rod motor drives the moving plate and related components to reset, completing the loading. Step 6: The first servo motor starts and drives the first rotating shaft to rotate. The first rotating shaft drives the turntable to rotate synchronously. The two sets of turntables drive the synchronous rod to move through the conveyor chain sleeved on the outside. The synchronous rod drives the clamped rotor to move towards the paint dripping assembly through the connecting mechanism.

[0020] Step 7: The second servo motor starts, and its output drives a set of sprockets to rotate. The two sets of sprockets drive the toothed chain on the outer side to move synchronously. The toothed chain meshes and drives the first gear to rotate. The first gear drives the synchronizing rod, connecting cylinder and rotor to rotate synchronously.

[0021] Step 8: The output pump starts and transports the insulating varnish in the collection box to the dripping tube through the pipeline. The insulating varnish drips from the outlet at the bottom of the dripping tube onto the rotating rotor winding, achieving full dripping.

[0022] Step 9: The rotor, after the paint dripping is completed, enters the drying chamber with the protective plate fixed under the drive of the moving mechanism. The drying module in the drying chamber is activated to dry the insulating paint on the surface of the rotor. During the drying process, the rotor continues to rotate.

[0023] Step 10: The dried rotor is transported by the moving mechanism to the loading and unloading mechanism on the other side of the worktable. The loading and unloading mechanism on this side repeats the reverse action of the loading stage. The robotic arm removes the dried rotor to complete the unloading.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] This invention completely replaces traditional manual loading and unloading operations through the coordinated operation of the loading and unloading mechanism, the connecting mechanism, and the connecting components. During loading, the first push rod motor drives the placement frame to precisely push the rotor to the connecting cylinder, and the third servo motor drives the pressure block to automatically clamp the rotor through gear transmission. The limiting mechanism clamps the first gear through a rack and pinion to ensure stable clamping. During unloading, the rotor can be automatically released and transferred by simply driving the relevant components in reverse. The entire process does not require manual installation, fixing, or disassembly of the rotor, which significantly improves the efficiency of mass production, reduces labor intensity, avoids the safety hazard of being scratched by moving parts of the equipment, and reduces labor input, effectively controlling the company's operating costs.

[0026] By further coordinating the design of the rotation component and the paint dripping component, the quality of the rotor's paint dripping can be ensured and material loss reduced. The rotation component is driven by a second servo motor to drive the gear chain, which in turn drives the first gear to rotate synchronously with the rotor. At the same time, the staggered paint outlets at the bottom of the paint dripping cylinder can drip the rotating rotor windings from all directions, avoiding the problem of uneven paint layer thickness caused by traditional fixed paint dripping. In addition, the rotor continues to rotate during the drying stage, which can ensure uniform drying of the paint layer, further improving the consistency of insulation performance and reducing the product defect rate. Excess insulating paint during the paint dripping process can be collected through a central frame, flow back to the collection box through the through hole, and then be transported back to the paint dripping cylinder by the output pump for recycling. This avoids the waste caused by the paint dripping directly, reduces production material costs, and reduces the pollution of the paint to the workbench and the surrounding environment, meeting the requirements of green production.

[0027] In summary, this invention significantly improves mass production efficiency, reduces labor intensity, avoids safety hazards caused by scratches from moving parts of equipment, and effectively controls enterprise operating costs. Attached Figure Description

[0052] like Figures 1 to 3 As shown, the present invention discloses an angle grinder motor rotor paint dripping machine, comprising a worktable 1 and support legs 11 supporting it. It also includes a moving mechanism 2 mounted on the worktable 1, which drives the rotor to move. The moving mechanism 2 includes multiple sets of mounting seats 21 fixedly connected to both ends of the worktable 1. A first rotating shaft 22 is rotatably connected to each mounting seat 21, and a turntable 23 is fixedly connected to the first rotating shaft 22. The turntable 23 maintains its original position and rotates through the mounting seats 21 and the first rotating shaft 22. A conveyor chain is sleeved on the outer side of the two sets of turntables 23. When the turntables 23 rotate, they drive the conveyor chain to move, thereby driving the rotor to move. The conveyor chain includes multiple sets of connecting pieces 24 and a rotating cylinder 25 rotatably connected between adjacent sets of connecting pieces 24. The rotating cylinder 25 rotatably connects the two sets of connecting pieces 24. When the turntables 23 rotate, they drive the connecting pieces 24 and the rotating cylinder 25 to move. A synchronizing rod 26 is rotatably connected to each of the multiple sets of rotating cylinders 25. A first servo motor 27 is mounted on the side of a set of mounting bases 21. The output end of the first servo motor 27 is fixedly connected to the first rotating shaft 22. The first servo motor 27 drives the turntable 23 to rotate through the set of first rotating shafts 22 fixedly connected to it, thereby driving the rotor connected to one end of the synchronizing rod 26 to move through the connecting mechanism 4.

[0053] In one embodiment, the above-mentioned paint dripping machine includes a self-rotating assembly 3 mounted on a worktable 1, which drives the rotor to rotate. The self-rotating assembly 3 includes two sets of sprockets 31 rotatably connected to both ends of the worktable 1, with the sprockets 31 rotating in their original positions. A toothed chain 32 is fitted around the outer side of each of the two sets of sprockets 31, and the sprockets 31 drive the toothed chain 32 to move when rotating. Multiple sets of synchronizing rods 26 each have one end fixedly connected to a first gear 33, which meshes with the toothed chain 32. When the toothed chain 32 moves, it drives the synchronizing rods 26 to rotate via the first gear 33, thereby driving the rotor connected to one end of the synchronizing rod 26 to rotate via the connecting mechanism 4. A second servo motor 34 is also mounted on the worktable 1, and the output end of the second servo motor 34 is fixedly connected to a set of sprockets 31, which drives the sprockets 31 to rotate.

[0054] For further details, please refer to Figures 3 to 5 The aforementioned paint dripping machine also includes a connecting mechanism 4 installed on the side of the moving mechanism 2 away from the rotating component 3. The connecting mechanism 4 is used to fix the rotor to the moving mechanism 2. The connecting mechanism 4 includes a connecting cylinder 41 fixedly connected to the end of the synchronizing rod 26 away from the first gear 33. The connecting cylinder 41 rotates synchronously with the synchronizing rod 26. Multiple sets of sliding grooves 42 are provided in the connecting cylinder 41, and the multiple sets of sliding grooves 42 are distributed in a circular array. Pressure blocks 43 are slidably connected in the sliding grooves 42. When the multiple sets of pressure blocks 43 converge towards the center, they clamp and fix one end of the rotor, so that the rotor rotates synchronously with the connecting cylinder 41. An inclined groove 44 is provided on the side of the pressure block 43 away from the synchronizing rod 26. An inclined block 45 is slidably connected in the inclined groove 44. When the inclined block 45 moves, it presses the position of the inclined groove 44, thereby driving the pressure block 43 to move towards the center position of the connecting cylinder 41. Multiple sets of inclined blocks 45 are fixedly connected to a sleeve 46 on their outer sides. When the sleeve 46 moves, it drives the multiple sets of inclined blocks 45 to move synchronously. The limiting effect of the multiple sets of inclined blocks 45 makes the movement of the sleeve 46 smooth. A synchronizing cylinder 47 is rotatably connected to the outer ring of the sleeve 46. The synchronizing cylinder 47 has an L-shaped cross-section. A threaded sleeve 48 is fixedly connected to the end of the synchronizing cylinder 47 away from the rotating cylinder 25. The threaded sleeve 48 is threadedly connected to the connecting cylinder 41. When the threaded sleeve 48 rotates, it moves along its own length direction. At the same time, when the threaded sleeve 48 rotates and moves, it drives the sleeve 46 to move through the synchronizing cylinder 47. A second gear 49 is fitted on the outer ring of the threaded sleeve 48. The second gear 49 rotates synchronously with the threaded sleeve 48. A spring groove 410 is provided in the pressure block 43, and a limit block 411 is slidably connected in the spring groove 410. The limit block 411 is fixedly connected to the inner wall of the slide groove 42. A first spring 412 is provided on the side of the limit block 411 away from the synchronous rod 26. When the inclined block 45 is reset and no longer presses the inclined groove 44, the elastic force of the first spring 412 can make the pressure block 43 move away from the middle position of the connecting cylinder 41, no longer press the fixed rotor, and make it easy for one end of the rotor to be taken out from the connecting cylinder 41.

[0055] Furthermore, such as Figure 6 and Figure 7 As shown, the above-mentioned paint dripping machine includes loading and unloading mechanisms 5 located on both sides of the worktable 1. The loading and unloading mechanisms 5 are used to realize the automatic loading and unloading of the rotor. The loading and unloading mechanism 5 includes a mounting plate 51 fixedly connected to the side of the support leg 11. The position of the mounting plate 51 is fixed. A first push rod motor 52 is mounted on the side of the mounting plate 51. A moving plate 53 is fixedly connected to the output end of the first push rod motor 52. After the first push rod motor 52 is started, it drives the moving plate 53 to move. The moving plate 53 is L-shaped. A second push rod motor 54 is mounted on the moving plate 53. A placement frame 55 is fixedly connected to the output end of the second push rod motor 54. After the second push rod motor 54 is started, it drives the placement frame 55 to rise and fall, thereby driving the rotor to rise and fall. In conjunction with the extension and retraction of the first push rod motor 52, it drives the rotor to move away from the connecting mechanism 4, which facilitates the automatic installation and disassembly of the rotor. The placement frame 55 is U-shaped, with two sets of coaxial arc grooves 56 on its top. These grooves allow the rotor shafts at both ends to engage, preventing the rotor from rolling on the frame. The placement and removal of the rotor are automatically controlled by a robotic arm, a mature existing technology that will not be elaborated upon here. Multiple sets of first sliders 57 are fixedly connected to the side of the moving plate 53 closest to the mounting plate 51. These first sliders 57 are slidably connected to first guide rails 58. These first guide rails 58 are collectively fixedly connected to a fixed frame 59, which is U-shaped and fixedly connected to the mounting plate 51. The fixed frame 59's position is fixed, thus fixing the position of the first guide rails 58. Combined with the limiting effect of the first sliders 57, this ensures smooth movement of the moving plate 53. A side plate 510 is fixedly connected to one side of the placement frame 55, and the side plate 510 moves synchronously with the placement frame 55. Multiple sets of second sliders 511 are installed on the side of the side plate 510. The second sliders 511 are slidably connected to the second guide rails 512, and the second guide rails 512 are fixedly connected to the moving plate 53. The limiting effect of the second sliders 511 and the second guide rails 512 ensures that the movement of the placement frame 55 is smooth. When installing the rotor, the rotor is placed on the placement frame 55. The first push rod motor 52 extends and drives one end of the rotor into the connecting cylinder 41. After the pressure block 43 locks the rotor, the second push rod motor 54 drives the placement frame 55 to move downward, which facilitates the movement of the rotor by the moving mechanism 2. Through two sets of loading and unloading mechanisms 5, loading is completed when the moving mechanism 2 is about to enter the position above the worktable 1, and unloading is carried out from below the worktable 1, realizing automation.

[0056] In one embodiment, the above-mentioned paint dripping machine also includes a connecting component 6 installed on the side of the loading and unloading mechanism 5 near the moving mechanism 2. The connecting component 6 is used to drive the connecting mechanism 4 to clamp the rotor. The connecting component 6 includes a synchronization frame 61 fixedly connected to the bottom of the placement frame 55. The synchronization frame 61 is U-shaped and moves synchronously with the placement frame 55. The synchronization frame 61 is located on the side near the second gear 49. A third servo motor 62 is installed on the side of the synchronization frame 61. The output end of the third servo motor 62 is fixedly connected to a third gear 63. After the third servo motor 62 starts, it drives the third gear 63 to rotate. A fourth gear 64 is provided above the third gear 63 and meshes with it. The fourth gear 64 meshes with the second gear 49. When the third gear 63 rotates, it drives the second gear 49 to rotate through the fourth gear 64, thereby driving the pressure block 43 to move towards the middle position of the connecting cylinder 41 to clamp one end of the rotor. A fixed shaft 65 is slidably connected to the fourth gear 64. The fixed shaft 65 is fixedly connected to the side of the placement frame 55. A second spring 66 is sleeved on the outer ring of the fixed shaft 65. The second spring 66 is located between the placement frame 55 and the fourth gear 64, allowing the second spring 66 to slide along the length of the fixed shaft 65 while rotating on it. The elastic force of the second spring 66 facilitates the reset of the fourth gear 64. A limiting plate 67 is fixedly connected to the end of the fixed shaft 65 away from the placement frame 55. The limiting plate 67 prevents the fourth gear 64 from disengaging from the fixed shaft 65.

[0057] It is worth mentioning that the thickness of the second gear 49 and the third gear 63 are both greater than the thickness of the fourth gear 64. When the first push rod motor 52 drives one end of the rotor into the connecting cylinder 41, the fourth gear 64 may be in a non-meshing state with the second gear 49. At this time, after the fourth gear 64 contacts the side of the second gear 49, it is blocked and cannot move forward. As the first push rod motor 52 continues to extend, the second spring 66 is compressed. When the third servo motor 62 starts and drives the fourth gear 64 to rotate slowly through the third gear 63, when the fourth gear 64 rotates to the meshing position with the second gear 49, the second spring 66 releases its elastic force, causing the fourth gear 64 to slide to the outside of the second gear 49 and mesh with it. When the second gear 49 rotates, it drives the threaded sleeve 48 to rotate synchronously. The threaded sleeve 48 moves along its own length direction, and the second gear 49 moves synchronously. However, because the thickness of the second gear 49 is greater than that of the fourth gear 64, the second gear 49 is always meshed with the fourth gear 64.

[0058] The third servo motor 62 is equipped with a torque sensor. After the threaded sleeve 48 drives the pressure block 43 to clamp, the torque sensor reaches a preset value, preventing excessive torque when the pressure block 43 locks one end of the rotor. The torque sensor is existing technology and will not be described in detail here.

[0059] As one implementation method, please refer to Figures 6 to 9 The aforementioned paint dripping machine also includes a limiting mechanism 7 located on the side of the moving mechanism 2 away from the loading and unloading mechanism 5. The limiting mechanism 7 is used to prevent the synchronous rod 26 from rotating when the second gear 49 rotates to lock the rotor. The limiting mechanism 7 includes a mounting frame 71 fixedly connected to the support leg 11, and the mounting frame 71 is fixed in position. A third push rod motor 72 is mounted on the side of the mounting frame 71, and a lifting plate 73 is fixedly connected to the output end of the third push rod motor 72. After the third push rod motor 72 is started, it drives the lifting plate 73 to rise and fall. Multiple sets of limiting rods 74 are slidably connected in the lifting plate 73, and a top plate 75 is fixedly connected to the top of the multiple sets of limiting rods 74. A third spring 77 is sleeved on the outer ring of the limiting rods 74. The third spring 77 is located between the lifting plate 73 and the top plate 75. When the lifting plate 73 moves upward, it drives the top plate 75 to move upward synchronously through the third spring 77. A rack 76 is installed on the top of the top plate 75. The rack 76 meshes with the first gear 33 to prevent the first gear 33 from rotating, thereby ensuring that the connecting cylinder 41 will not be affected by friction when the second gear 49 and the threaded sleeve 48 rotate. A sliding sleeve 78 is slidably fitted on the limiting rod 74. The sliding sleeve 78 is fixedly connected to the mounting frame 71. The limiting action of the limiting rod 74 and the sliding sleeve 78 allows the lifting plate 73 and the top plate 75 to move smoothly.

[0060] When the first gear 33 is in a non-meshing position with the rack 76, the rack 76 moves upward and contacts the first gear 33. At the same time, the third push rod motor 72 continues to extend and drives the lifting plate 73 to move upward, compressing the third spring 77. When the second gear 49 and the threaded sleeve 48 rotate, the frictional force drives the synchronizing rod 26 to rotate, thereby driving the first gear 33 to rotate. When the first gear 33 rotates to the meshing position with the rack 76, the third spring 77 releases its elastic force, causing the rack 76 to be stuck under the second spring 66. Because the rack 76 is unable to move laterally due to the action of the limiting rod 74 and the sliding sleeve 78, the second spring 66 cannot rotate, ensuring that the position of the connecting cylinder 41 is fixed when the second gear 49 and the threaded sleeve 48 rotate.

[0061] In one embodiment, the above-mentioned paint dripping machine includes a paint dripping assembly 8 disposed on a worktable 1, which is used to drip paint onto a rotating rotor. The paint dripping assembly 8 includes multiple sets of paint dripping cylinders 81 disposed above the worktable 1, the multiple sets of paint dripping cylinders 81 being equidistantly arranged in an array, the positions of the paint dripping cylinders 81 corresponding to the rotor positions. Multiple sets of paint outlets are provided at the bottom of the paint dripping cylinders 81, the positions of the paint outlets at the bottom of adjacent sets of paint dripping cylinders 81 being staggered to facilitate comprehensive paint dripping operation on the rotor. A fixing frame 82 is fixedly connected to the paint dripping cylinders 81, and a collection frame 83 installed on the top of the worktable 1 is disposed below the multiple sets of paint dripping cylinders 81 to collect the paint dripping down the rotor. A collection box 84 is installed at the bottom of the worktable 1 below the collection frame 83, and a through hole 85 is provided at a corresponding position on the worktable 1 and the collection box 84. The through hole 85 is located inside the collection frame 83, and the paint above the worktable 1 enters the collection box 84 for storage through the through hole 85. An output pump 86 is installed on the side of the collection box 84. The output end of the output pump 86 is connected to multiple sets of paint dripping cylinders 81 through a pipe. The output pump 86 is used to transport the paint in the collection box 84 to the paint dripping cylinders 81 for recycling.

[0062] Furthermore, the aforementioned paint-dispensing machine also includes a protective plate 9 installed on top of the workbench 1. The protective plate 9 is L-shaped and provides protection above the workbench 1. Multiple sets of fixing brackets 82 are fixedly connected to the protective plate 9, thus fixing the position of the paint-dispensing cylinder 81. A drying chamber 91 is fixedly connected to the protective plate 9. The moving mechanism 2 and the rotating component 3 are both installed in the drying chamber 91. The drying chamber 91 is equipped with a drying module to facilitate the drying of the paint on the rotor. This is existing technology and will not be described in detail here.

[0063] It is worth mentioning that in this embodiment, all electrical devices are controlled collaboratively through the control module to achieve automated control.

[0064] In this embodiment, a robotic arm places the angle grinder motor rotor to be dripped with paint into the placement frame 55 of the loading / unloading mechanism 5 on one side of the worktable 1. The shafts at both ends of the rotor are engaged in the arc grooves 56 at the top of the placement frame 55 to prevent the rotor from rolling. At this time, the first push rod motor 52 starts, and its output end pushes the moving plate 53 to move along the first guide rail 58. During the movement, the first slider 57 cooperates with the first guide rail 58 to ensure smooth movement. The moving plate 53 drives the second push rod motor 54 and the placement frame 55 to move synchronously until one end of the rotor is aligned with the connecting cylinder 41 of the connecting mechanism 4 in the moving mechanism 2. While the first push rod motor 52 pushes the rotor closer to the connecting cylinder 41, the synchronization frame 61 at the bottom of the placement frame 55 drives the connecting assembly 6 to move synchronously. Then, the third servo motor 62 starts, and its output end drives the third gear 63 to rotate. The third gear 63 meshes with the fourth gear 64 to rotate. If the fourth gear 64 is not meshed with the second gear 49 in the initial state, the fourth gear 64 will compress the second spring 66 after contacting the side of the second gear 49. When the fourth gear 64 rotates to the meshing position with the second gear 49, the second spring 66 releases its elastic force to push the fourth gear 64 to slide along the fixed shaft 65, thereby achieving stable meshing with the second gear 49.

[0065] Simultaneously, the output of the third push rod motor 72 pushes the lifting plate 73 to rise along the limiting rod 74 inside the sliding sleeve 78. The lifting plate 73 drives the top plate 75 to rise via the third spring 77 until the rack 76 at the top of the top plate 75 contacts the first gear 33. If the first gear 33 is not initially engaged with the rack 76, the third push rod motor 72 continues to extend and compress the third spring 77. When the second gear 49 drives the synchronizing rod 26 to rotate slightly, aligning the first gear 33 with the rack 76, the third spring 77 releases its elasticity, causing the rack 76 to clamp the first gear 33, preventing the synchronizing rod 26 from rotating. Subsequently, the second gear 49 rotates under the drive of the fourth gear 64, causing the threaded sleeve 48 to move along the thread of the connecting cylinder 41. The sleeve 46 drives multiple sets of inclined blocks 45 to move synchronously. The inclined blocks 45 press against the inclined groove 44, pushing the pressure block 43 towards the center of the connecting cylinder 41 until one end of the rotor is clamped. When the torque sensor of the third servo motor 62 detects that the torque has reached the preset value, the motor stops running to avoid over-clamping and damaging the rotor. Then, the second push rod motor 54 starts, and its output end drives the placement frame 55 to descend along the second guide rail 512. The descent is ensured to be smooth by the cooperation between the second slider 511 and the second guide rail 512. After the placement frame 55 is separated from the rotor, the first push rod motor 52 drives the moving plate 53 and related components to reset, completing the loading.

[0066] Then, the first servo motor 27 starts, and its output drives the first rotating shaft 22 to rotate. The first rotating shaft 22 drives the turntable 23 to rotate synchronously. The two sets of turntables 23 are connected by a conveyor chain on the outside, consisting of a connecting piece 24 and a rotating cylinder 25, which drives the synchronous rod 26 to move. The synchronous rod 26 drives the clamped rotor to move towards the paint dripping assembly 8 through the connecting mechanism 4. After the rotor is delivered to the position, the second servo motor 34 starts, and its output drives a set of sprockets 31 to rotate. The two sets of sprockets 31 are connected by a toothed chain 32 on the outside to move synchronously. The toothed chain 32 meshes and drives the first gear 33 to rotate. The first gear 33 drives the synchronous rod 26, the connecting cylinder 41, and the rotor to rotate synchronously. At this time, the output pump 86 of the paint dripping assembly 8 starts, and the insulating varnish in the collection box 84 is transported to the paint dripping cylinder 81 through the pipeline. The insulating varnish is dripped onto the rotating rotor winding through the varnish outlet at the bottom of the paint dripping cylinder 81, achieving comprehensive paint dripping. During the dripping process, excess insulating varnish drips into the collection frame 83 and flows back to the collection box 84 through the through hole 85 of the workbench 1, thus realizing the recycling of the varnish.

[0067] The rotor, after the paint has been applied, enters the drying chamber 91, which is fixed by the protective plate 9, driven by the moving mechanism 2. The drying module inside the drying chamber 91 is activated to dry the insulating paint on the surface of the rotor. During the drying process, the rotor continues to rotate to ensure that the paint layer dries evenly.

[0068] After drying, the rotor is conveyed by the moving mechanism 2 to the loading / unloading mechanism 5 on the other side of the worktable 1. The loading / unloading mechanism 5 on this side repeats the reverse action of the loading stage. The second push rod motor 54 drives the placement frame 55 to rise below the rotor, and the first push rod motor 52 pushes the placement frame 55 closer to the rotor, and the arc groove 56 clamps the other end of the rotor. Subsequently, the third servo motor 62 rotates in the reverse direction, driving the second gear 49 and the threaded sleeve 48 to move in the reverse direction. The inclined block 45 disengages from the inclined groove 44, and the pressure block 43 resets to both sides of the slide groove 42 under the elastic force of the first spring 412, releasing the rotor. Finally, the first push rod motor 52 drives the placement frame 55 and the rotor away from the connecting mechanism 4, the second push rod motor 54 drives the placement frame 55 to descend, and the robotic arm removes the dried rotor, completing the unloading.

[0069] This invention proposes a method for using an angle grinder motor rotor paint spraying machine, comprising the following steps:

[0070] Step 1: The robotic arm places the angle grinder motor rotor to be dripped with paint into the placement frame 55 of the loading and unloading mechanism 5 on one side of the worktable 1, and the shafts at both ends of the rotor are inserted into the arc groove 56 at the top of the placement frame 55.

[0071] Step 2: The first push rod motor 52 is started, pushing the moving plate 53 to move along the first guide rail 58, causing one end of the rotor to align with the connecting cylinder 41 of the connecting mechanism 4 in the moving mechanism 2;

[0072] Step 3: The third servo motor 62 starts and drives the third gear 63 to rotate. The third gear 63 meshes with and drives the fourth gear 64 to rotate, achieving stable meshing with the second gear 49.

[0073] Step four: The output end of the third push rod motor 72 pushes the lifting plate 73 to rise. The lifting plate 73 drives the top plate 75 to rise through the third spring 77 until the rack 76 at the top of the top plate 75 meshes with the first gear 33. Subsequently, the second gear 49 rotates under the drive of the fourth gear 64, causing the threaded sleeve 48 to move along the thread of the connecting cylinder 41. The sleeve 46 drives multiple sets of inclined blocks 45 to move synchronously. The inclined blocks 45 squeeze the inclined groove 44 and push the pressure block 43 to gather towards the center of the connecting cylinder 41 until one end of the rotor is clamped.

[0074] Step 5: The second push rod motor 54 starts and drives the placement frame 55 to descend along the second guide rail 512. After the placement frame 55 is separated from the rotor, the first push rod motor 52 drives the moving plate 53 and related components to reset, completing the loading.

[0075] Step 6: The first servo motor 27 starts and drives the first rotating shaft 22 to rotate. The first rotating shaft 22 drives the turntable 23 to rotate synchronously. The two sets of turntables 23 drive the synchronous rod 26 to move through the conveyor chain sleeved on the outside. The synchronous rod 26 drives the clamped rotor to move towards the paint dripping assembly 8 through the connecting mechanism 4.

[0076] Step 7: The second servo motor 34 starts, and its output drives a set of sprockets 31 to rotate. The two sets of sprockets 31 drive the toothed chain 32 on the outer side to move synchronously. The toothed chain 32 meshes and drives the first gear 33 to rotate. The first gear 33 drives the synchronizing rod 26, the connecting cylinder 41 and the rotor to rotate synchronously.

[0077] Step 8: The output pump 86 is started, and the insulating varnish in the collection box 84 is transported to the dripping tube 81 through the pipeline. The insulating varnish is dripped onto the rotating rotor winding through the varnish outlet at the bottom of the dripping tube 81, so as to achieve full dripping.

[0078] Step 9: The rotor that has completed the varnishing process enters the drying chamber 91 fixed by the protective plate 9 under the drive of the moving mechanism 2. The drying module in the drying chamber 91 is activated to dry the insulating varnish on the surface of the rotor. During the drying process, the rotor continues to rotate.

[0079] Step 10: The dried rotor is transported by the moving mechanism 2 to the loading and unloading mechanism 5 on the other side of the workbench 1. The loading and unloading mechanism 5 on this side repeats the reverse action of the loading stage. The robotic arm removes the dried rotor and completes the unloading.

[0080] The above specific embodiments are merely optional embodiments of the present invention.
