Description

Technical Field

[0001] This application relates to the field of stator manufacturing technology, and in particular to a brushless motor stator oil injection device. Background Technology

[0002] The stator of a brushless motor is the fixed core component of the motor. It mainly consists of an iron core made of laminated silicon steel sheets, windings (copper wire coils) wound in the slots of the iron core, and a fixing structure. Its core function is to generate a rotating magnetic field by passing alternating current through it, thereby driving the motor rotor to rotate. In applications, brushless motor stators are widely used in various devices that rely on brushless motors, such as drive motors for household air conditioners and washing machines, drive and auxiliary motors for new energy vehicles, servo motors and water pump motors in the industrial field, and the power core of small devices such as drones and power tools.

[0003] Rust-preventive oil is injected during stator production because components such as the silicon steel core and metal joints of the winding leads are prone to oxidation and rusting during storage after production and before assembly, due to exposure to air and moisture. This not only affects the motor's conductivity and operational stability but may also shorten its lifespan. Therefore, rust-preventive oil is needed to form a protective film. The oiling process typically begins with cleaning the stator to remove surface oil, dust, and other impurities. Then, a suitable oiling method is selected based on the stator's specifications—small stators often use an immersion method (completely immersing the stator in rust-preventive oil for a certain period to ensure sufficient oil coating on critical areas), while large or precision stators commonly use a spraying or dripping method (precisely spraying or dripping rust-preventive oil onto easily rusted areas such as the core slots and metal joints). After oiling, excess grease is drained or the stator is dried at low temperature to ensure a uniform oil film that does not affect subsequent assembly.

[0004] An existing brushless motor stator oiling device involves workers placing the stator into a testing structure for testing, followed by placing it into the oiling structure for oiling. However, the testing and oiling process requires manual insertion and removal of the stator, which wastes considerable time and results in low stator oiling efficiency, hindering stator production. Summary of the Invention

[0005] The purpose of this application is to solve the problem in the above-mentioned background technology that when testing and lubricating the stator, it is necessary to manually insert and remove the stator to make corresponding changes, which wastes a lot of time and results in low stator lubrication efficiency, which is not conducive to the production of motor stators. This application provides a brushless motor stator lubrication device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A brushless motor stator oiling device includes a workbench, an operating cover fixedly connected to the top of the workbench, an oiling component fixedly connected to the middle of the top of the workbench, a clamping component fixedly connected to the rear side of the middle of the top of the workbench, a feeding component fixedly connected to one side of the top of the workbench, and a finished product conveyor belt fixedly connected to the other side of the top of the workbench. A start button is fixedly connected to one end of the workbench. A controller is installed on the operating cover. A vision sensor is fixedly connected to one side of the top of the workbench, located above the initial feeding end of the feeding component. A power supply is provided at the feeding end of the feeding component. An oil receiving component is installed on the top of the oiling component, and fixing components are installed on both sides of the top of the oiling component. The controller is electrically connected to the oiling component, the feeding component, the power supply, the clamping component, and the vision sensor.

[0007] By adopting the above technical solution, the stator is placed on the feeding component, and the model and position of the stator are detected by a vision sensor. Then, the stator is conveyed to the power supply unit by the feeding component for power-on testing. After passing the test, the stator is clamped by the clamping component and conveyed to the oiling component for oiling. After oiling, the stator is clamped by the clamping component and placed on the finished product conveyor belt. This completes the testing and oiling of the stator, thereby realizing the automated processing of the stator and improving the production efficiency of the stator.

[0008] Furthermore, the feeding component includes an L-shaped connecting plate disposed on one side of the top of the workbench, a slide rail is mounted on the top of the L-shaped connecting plate, a sliding seat is mounted on the slide rail, an energized clamp is fixedly connected to the top of the sliding seat, and an energized head is fixedly connected to one side of the top of the sliding seat. A telescopic cylinder is fixedly connected to one side of the L-shaped connecting plate, and the output end of the telescopic cylinder is connected to the sliding seat.

[0009] By adopting the above technical solution, the operation of the telescopic cylinder one drives the L-shaped connecting plate to move, which in turn drives the sliding seat to slide on the guide rail, thereby driving the energized head to move towards the energizer, which in turn drives the stator to move below the energizer.

[0010] Furthermore, the oiling component includes an oiling seat fixedly connected to the top of the workbench, an oiling platform fixedly connected to the top of the oiling seat, an oil pump installed inside the oiling seat, an oiling clamp fixedly connected to the top of the oiling platform, an oiling port opened on the oiling clamp, the oiling clamp is connected to the output end of the oil pump, and a touch sensor is provided on the oiling clamp.

[0011] By adopting the above technical solution, the rust-preventive oil inside the external oil tank can be injected into the stator through an oil pump, thereby achieving the oil injection treatment of the stator.

[0012] Furthermore, the clamping component includes a connecting plate fixedly connected to the top of the workbench, a track fixedly connected to the top of the connecting plate, a telescopic cylinder two fixedly connected to one end of the track, and a movable seat slidably connected to the track. The output end of the telescopic cylinder two is connected to the movable seat, a telescopic cylinder three fixedly connected to the movable seat, a movable plate fixedly connected to the output end of the telescopic cylinder three, and pneumatic grippers fixedly connected to both ends of the movable plate.

[0013] By adopting the above technical solution, the operation of the telescopic cylinder two drives the moving seat to move on the track, thereby moving the moving seat towards the position of the stator. The operation of the telescopic cylinder three drives the moving plate to press down, and then the pneumatic gripper clamps the stator.

[0014] Furthermore, the fixing component includes a mounting rod fixedly connected to one side of the top of the oil filling platform, an L-shaped drive plate rotatably connected to the mounting rod, an arc-shaped clamping plate fixedly connected to one side of the top of the L-shaped drive plate, and an electric push rod rotatably connected to one side of the top of the oil filling platform, with one end of the electric push rod rotatably connected to the L-shaped drive plate.

[0015] By adopting the above technical solution, the stator can be clamped by two arc-shaped clamps against the outer wall of the stator, thereby further fixing the stator.

[0016] Furthermore, the oil receiving component includes an annular oil receiving plate slidably mounted on the oil injection head, with sliders fixedly connected to both sides of the annular oil receiving plate, and linkage components installed on both sides of the oil injection platform, with the sliders located inside the linkage components.

[0017] By adopting the above technical solution, when the stator is oiled, if the anti-rust oil leaks out from the stator, it can naturally fall into the annular oil receiving plate.

[0018] Furthermore, an oil guide slope is provided on the inner side of the annular oil receiving plate, and the inner bottom of the oil guide slope is connected to mutually symmetrical return pipes.

[0019] By adopting the above technical solution, the rust-preventive oil can be introduced into an external oil tank through the return pipe, thereby collecting and treating any leaked rust-preventive oil.

[0020] Furthermore, the linkage includes a U-shaped frame fixedly connected to one side of the top of the oil filling platform, the slider slidably connected inside the U-shaped frame, a guide rope pulley installed on the top of the U-shaped frame, a tension spring fixedly connected between the oil filling platform and the slider, a pull rope fixedly connected to the top of the slider, the pull rope being wound around the guide rope pulley, and one end of the pull rope being connected to one end of the L-shaped drive plate.

[0021] By adopting the above technical solution, when the L-shaped drive plate rotates, it can pull the pull rope, so that one end of the pull rope pulls the slider, causing the slider to drive the annular oil receiving plate to move upward.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, the stator is placed on the feeding component, and the model and position of the stator are detected by a vision sensor. Then, the stator is conveyed to the power supply unit by the feeding component for power-on testing. After passing the test, the stator is clamped by the clamping component and conveyed to the oiling component for oiling. After oiling, the stator is clamped by the clamping component and then conveyed to the finished product conveyor belt. This completes the testing and oiling of the stator, thereby realizing the automated processing of the stator and improving the production efficiency of the stator.

[0023] 2. In this application, when the stator is conveyed to the oiling component by the clamping component, the stator can contact the touch sensor on the oiling component. After contact, the touch sensor can transmit a signal to the controller, which then drives the fixing component to rotate, thereby causing the internal components of the fixing component to contact the outer wall of the stator and clamp and fix it, thus further fixing the stator on the oiling component, preventing the stator from shaking during oiling, improving the stability of stator oiling, and reducing the risk of oil leakage.

[0024] 3. In this application, while the fixing component is running, its internal components can be simultaneously driven to connect to the oil receiving component, so that the internal components of the oil receiving component operate, thereby driving its internal structure to fit against the bottom and outer bottom of the stator, thus achieving the sealing of the bottom of the stator. When the rust-preventive oil leaks during oiling, it can be received through the oil receiving component and flowed back into the external oil tank, thereby protecting the stator from oiling, further improving the stability of oiling, preventing oil leakage from polluting the surrounding environment, and reducing the consumption of rust-preventive oil when oil leakage occurs.

[0027] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0028] This application discloses a brushless motor stator oil injection device.

[0029] Reference Figure 1 and Figure 2 A brushless motor stator oiling device includes a workbench 1, an operating cover 2 fixedly connected to the top of the workbench 1, an oiling component 3 fixedly connected to the middle of the top of the workbench 1, a clamping component 7 fixedly connected to the rear side of the middle of the top of the workbench 1, a feeding component 4 fixedly connected to one side of the top of the workbench 1, and a finished product conveyor belt 11 fixedly connected to the other side of the top of the workbench 1. A start button 6 is fixedly connected to one end of the workbench 1. A controller 12 is installed on the operating cover 2. A vision sensor 10 is fixedly connected to one side of the top of the workbench 1. The vision sensor 10 is located above the initial feeding end of the feeding component 4. A power supply 5 is provided at the feeding end of the feeding component 4. An oil receiving component 9 is installed on the top of the oiling component 3, and fixing components 8 are installed on both sides of the top of the oiling component 3. The controller 12 is electrically connected to the oiling component 3, the feeding component 4, the power supply 5, the clamping component 7, and the vision sensor 10.

[0030] When testing and lubricating the motor stator, the stator is first inserted into the feeding component 4. After insertion, the model and position of the stator can be visually detected by the vision sensor 10. Then, by manually pressing the start button 6, the start button 6 transmits a signal to the controller 12, which operates the feeding component 4 to transport the stator to the power supply 5. The power supply 5 performs an electrical test on the stator. When the test is passed, the feeding component 4 drives the stator to reset. Then, the clamping component 7 clamps the stator at the feeding component 4 and transports it to the lubrication component 3. If the test fails, the controller 12 issues an alarm to alert nearby personnel so that the unqualified stator can be removed. When the qualified stator is transported to the lubrication component 3 by the clamping component 7, it touches the contact sensor on the lubrication component 3. The sensor 35 contacts the stator, and the sensor 35 transmits a signal to the controller 12, which then drives the fixing component 8 to rotate. This causes the internal components of the fixing component 8 to contact the outer wall of the stator and clamp and fix them. The oiling component 3 can be used to inject rust-preventive oil into the stator. While the fixing component 8 is running, its internal components can be driven to connect to the oiling component 9, causing the internal components of the oiling component 9 to rotate. This causes its internal structure to fit against the bottom and outer bottom of the stator, thus sealing the bottom of the stator. If rust-preventive oil leaks during injection, it can be collected by the oiling component 9 and returned to the external oil tank, thus protecting the stator from oiling. After oiling, the stator can be clamped again by the clamping component 7 and sent to the finished product conveyor belt 11, thus realizing the testing and oiling treatment of the stator.

[0031] Reference Figures 3 to 5The feeding component 4 includes an L-shaped connecting plate 41 disposed on one side of the top of the workbench 1. A slide rail is installed on the top of the L-shaped connecting plate 41, and a sliding seat 43 is installed on the slide rail. A power-conducting clamp 44 is fixedly connected to the top of the sliding seat 43, and a power-conducting head 45 is fixedly connected to one side of the top of the sliding seat 43. A telescopic cylinder 42 is fixedly connected to one side of the L-shaped connecting plate 41, and the output end of the telescopic cylinder 42 is connected to the sliding seat 43. The oiling component 3 includes an oiling seat 31 fixedly connected to the top of the workbench 1. An oiling platform 32 is fixedly connected to the top of the oiling seat 31, and an oil pump is installed inside the oiling seat 31. An oiling clamp is fixedly connected to the top of the oiling platform 32. The head 33 has an oil inlet 34 and is connected to the output end of the oil pump. The oil inlet 33 is equipped with a touch sensor 35. The clamping component 7 includes a connecting plate 71 fixedly connected to the top of the workbench 1. A track 72 is fixedly connected to the top of the connecting plate 71. A telescopic cylinder 73 is fixedly connected to one end of the track 72, and a movable seat 74 is slidably connected to the track 72. The output end of the telescopic cylinder 73 is connected to the movable seat 74. A telescopic cylinder 75 is fixedly connected to the movable seat 74. A movable plate 76 is fixedly connected to the output end of the telescopic cylinder 75. Pneumatic grippers 77 are fixedly connected to both ends of the movable plate 76.

[0032] The stator is inserted into the energizing clamp 44. Then, the operation of the telescopic cylinder 42 moves the L-shaped connecting plate 41, causing the sliding seat 43 to slide on the guide rail. This, in turn, moves the energizing clamp 44 towards the power supply 5, thus moving the stator below the power supply 5. During this process, the stator is energized for testing in cooperation with the power supply 5. After the power supply 5 energizes the stator for testing, the operation of the telescopic cylinder 73 moves the moving seat 74 on the track 72. The moving seat 74 is moved toward the stator, and the operation of the telescopic cylinder 3 75 causes the moving plate 76 to press down. The pneumatic gripper 77 then clamps the stator, and the telescopic cylinder 2 73 drives the moving seat 74 to move the stator toward the oiling part 3. The stator is then placed on the oiling head 33. After that, the oil pump delivers the rust-preventive oil from the external oil tank to the oiling head 33, and the rust-preventive oil is injected into the stator through the oiling port 34, thus completing the oiling process for the stator.

[0033] Reference Figure 6 The fixing component 8 includes a mounting rod 81 fixedly connected to one side of the top of the oil filling platform 32. An L-shaped drive plate 82 is rotatably connected to the mounting rod 81. An arc-shaped clamping plate 84 is fixedly connected to one side of the top of the L-shaped drive plate 82. An electric push rod 83 is rotatably connected to one side of the top of the oil filling platform 32. One end of the electric push rod 83 is rotatably connected to the L-shaped drive plate 82.

[0034] The electric actuator 83 extends under the operation of the electric actuator 83, which in turn pushes the L-shaped drive plate 82, causing the L-shaped drive plate 82 to rotate on the mounting rod 81. This drives the arc-shaped clamping plate 84 to move towards the stator. The two arc-shaped clamping plates 84 can abut against the outer wall of the stator, thereby clamping the stator and further fixing it.

[0035] Reference Figure 7 and Figure 8 The oil receiving component 9 includes an annular oil receiving plate 91 slidably mounted on the oil filling head 33. Sliders 93 are fixedly connected to both sides of the annular oil receiving plate 91. Linkage components are installed on both sides of the oil filling platform 32. The sliders 93 are located inside the linkage components. An oil guide slope 92 is provided on the inner side of the annular oil receiving plate 91. The bottom of the oil guide slope 92 is connected to mutually symmetrical return pipes 94. The linkage component includes a U-shaped frame 95 fixedly connected to one side of the top of the oil filling platform 32. The slider 93 is slidably connected inside the U-shaped frame 95. A guide rope pulley 97 is installed on the top of the U-shaped frame 95. A tension spring 96 is fixedly connected between the oil filling platform 32 and the slider 93. A pull rope 98 is fixedly connected to the top of the slider 93. The pull rope 98 is wound around the guide rope pulley 97, and one end of the pull rope 98 is connected to one end of the L-shaped drive plate 82.

[0036] When the L-shaped drive plate 82 rotates, it can pull the pull rope 98, causing one end of the pull rope 98 to pull the slider 93. This causes the slider 93 to move the annular oil receiving plate 91 upward, thus fitting it against the bottom of the stator. When the stator is being oiled, if rust-preventive oil leaks from the stator, it will naturally fall into the annular oil receiving plate 91. During this process, it will be guided by the oil guide slope 92 and flow into the return pipe 94. The return pipe 94 can then guide the rust-preventive oil into an external oil tank, thus collecting and treating the leaked rust-preventive oil, preventing it from polluting the surrounding environment, and avoiding waste.

[0037] Working Principle: First, the operator inserts the stator to be processed onto the energized clamp 44. After insertion, the vision sensor 10 is activated to visually inspect the stator's model, specifications, and installation position, ensuring accurate execution of subsequent processes. After inspection, the operator manually presses the start button 6, which sends a trigger signal to the controller 12. The controller 12 then issues an action command to the feeding component 4, driving the telescopic cylinder 42 to rotate. The telescopic cylinder 42 moves the L-shaped connecting plate 41 linearly, which in turn moves the sliding seat 43 synchronously along the guide rail, ultimately pushing the energized clamp 44 along with the stator towards the power supply 5, bringing the stator directly below the power supply 5. During this movement, the energized head 45 and the power supply 5 cooperate to perform an energization performance test on the stator. If the test fails, the controller 12 immediately issues an alarm signal, alerting nearby personnel to remove the defective stator. If the test passes, the feeding component 4 drives the stator back to its initial position.

[0038] After the stator passes the test, the controller 12 activates the clamping component 7, the telescopic cylinder 2 73 operates and drives the moving seat 74 to slide along the track 72, bringing the moving seat 74 closer to the stator. Then, the telescopic cylinder 3 75 drives the moving plate 76 to press down, and the pneumatic gripper 77 moves synchronously to stably clamp the stator. After clamping, the telescopic cylinder 2 73 drives the moving seat 74 to slide in the opposite direction, moving the stator towards the oiling component 3, and finally accurately inserting the stator into the oiling clamp head 33. When the stator contacts the touch sensor 35 on the oiling component 3, the touch sensor 35 sends a positioning signal to the controller 12. The controller 12 then drives the fixing component 8 to move, the electric push rod 83 extends after being energized, and applies a pushing force to the L-shaped drive plate 82, causing the L-shaped drive plate 82 to rotate around the mounting rod 81, thereby driving the two arc-shaped clamping plates 84 to move towards the stator. The contact between the arc-shaped clamping plates 84 and the outer wall of the stator achieves a firm clamping of the stator. Meanwhile, when the L-shaped drive plate 82 rotates, it pulls the pull rope 98. The other end of the pull rope 98 drives the slider 93 to move. The slider 93 drives the annular oil receiving plate 91 to move upward and fit against the bottom of the stator, achieving a sealed protection at the bottom of the stator. Then, the oil pump starts, injecting the anti-rust oil from the external oil tank into the stator to complete the oiling process. If anti-rust oil leaks during the oiling process, the annular oil receiving plate 91 can collect the leaked oil and return it to the external oil tank, avoiding resource waste and environmental pollution. After the oiling operation is completed, the clamping component 7 moves again to clamp the stator and transport it to the finished product conveyor belt 11, finally completing the entire process testing and oiling treatment of the stator.
