Description

Technical Field

[0001] The present invention relates to the technical field of motor production, and particularly to a magnetic steel misalignment detection system for the production of nano-permanent magnet disc motors. Background Art

[0002] When a motor is being produced and processed, magnetic steel needs to be installed around the rotor. When installing the magnetic steel in a disc motor, it is necessary to ensure that the magnetic steel is misaligned by 7.5° relative to the center of the rotor during installation, so as to ensure that the motor has optimal performance.

[0003] Currently, after the magnetic steel of the motor is installed, a magnetic steel sheath is often directly sleeved on the outside of the motor, which increases the difficulty of detecting the misalignment of the magnetic steel in the later stage. The magnetic steel is mostly installed on the outside of the rotor by coating magnetic steel glue on the outside of the rotor and then sticking the magnetic steel on the outside of the rotor. The magnetic steel sheath is generally installed by a hydraulic sleeving method. For some magnetic steels with unstable installation, during the installation process of the magnetic steel sheath, the magnetic steel will shift, affecting the production quality of the motor.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the present invention, by providing a laser detection head, a turning plate and an arc-shaped block, the turning plate is driven to rotate by a first rotating shaft. Combining with the second rotating shaft driving the fixed frame to rotate by a preset angle and the third rotating shaft driving the laser detection head to rotate by a preset angle, through this operation mode, the system can perform misalignment detection on the magnetic steels of different types of motors, increasing the functional applicability of the system;

[0018] The motor rotor moves closer to the arc-shaped block. After moving to the preset position, the air outlet jets air, and the second rotating motor drives the lifting disc to rotate, enabling the motor rotor to rotate. During the rotation of the motor rotor, by blowing air on the motor rotor through the air outlet and brushing the motor rotor with the cleaning brush on the arc-shaped block, the motor rotor can be cleaned, ensuring the production quality of the motor rotor.

[0019] In the present invention, by providing an abutting block and a clamping plate, the clamping plate moves above the top of the magnetic steel of the motor rotor. The abutting block moves downward through the sliding of the lifting slider in the lifting chute. When the top of the clamping plate abuts against the top of the magnetic steel, the abutting block continues to move downward. As the abutting block moves downward, the movable block slides downward inside the first slot. The movable block squeezes the telescopic connecting rod, and the telescopic connecting rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system. The abutting block continues to press down until the pressure value measured by the pressure sensor reaches the preset pressure value. During this period, the change of the magnetic steel is observed through the camera. Through this operation mode, the installation stability of the magnetic steel can be detected;

[0020] The abutting block moves to the preset height position of the magnetic steel of the motor rotor, and then the magnetic steel is fixed by the abutting block abutting against the magnetic steel. The magnetic steel sheath installation machine starts to sleeve the magnetic steel sheath on the outer side of the motor rotor. Through this operation mode, it can prevent the magnetic steel on the outer side of the motor rotor from shifting during the downward sleeving process of the magnetic steel sheath when the motor rotor is sleeved with the magnetic steel sheath, affecting the production quality of the motor.

[0021] In the present invention, by providing a lifting disc and a first electric slider, the fixing plate on the lifting disc can complete the clamping and fixing of the rotating shaft of the motor rotor, increasing the detection stability of the system for the motor rotor. By driving the movable disc to move on the fixed base through the first electric slider, the classification and blanking of the qualified and unqualified motor rotors can be completed, increasing the convenience of using the system.

Specific implementation manner

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Referring to Figures 1 - 14 , a magnetic steel misalignment detection system for the production of a nano-permanent disk motor, includes a fixed base 1.

By providing a detection mechanism, the misalignment detection of the magnetic steel of the motor can be completed. The cleaning mechanism can complete the cleaning of the outer side of the motor rotor and the outer magnetic steel, ensuring the production quality of the motor. The auxiliary mechanism can complete the detection of the installation stability of the magnetic steel and fix the magnetic steel when installing the magnetic steel sheath of the motor, preventing the magnetic steel from running off. The fixing mechanism can complete the fixation of the motor.

[0039] As a technical optimization scheme of the present invention, a first rotating motor 9 is embedded and installed at the top of one end of the fixed base 1. The output end of the first rotating motor 9 faces upward. The output end of the first rotating motor 9 is connected to the bottom of the electric lifting rod 4. The first rotating motor 9 can drive the electric lifting rod 4 to rotate according to the use requirements, so that the mechanisms connected to the electric lifting rod 4 will not interfere with the operation of other mechanisms on the system when not in use, increasing the operation stability of the system.

[0040] As a technical optimization solution of the present invention, the detection mechanism includes a flipping plate 31 and a laser detection head 32. A third slot 30 is opened at the bottom of the support plate 5. The flipping plate 31 is movably installed inside the third slot 30. A plurality of fourth slots 34 are opened at the bottom of the flipping plate 31. A fixing frame 35 is movably installed inside the fourth slots 34. A fifth slot 37 is opened at the bottom of the fixing frame 35. The laser detection head 32 is movably installed inside the fifth slot 37. The laser detection head 32 moves above the motor rotor, and the laser detection head 32 rotates at a preset angle. The laser detection head 32 can detect the inclination angle of the magnetic steel on the motor rotor. Through this operation method, the misalignment detection of the magnetic steel of the motor can be completed.

[0041] As a technical optimization solution of the present invention, first rotating shafts 33 are embedded and installed on both side walls of the third slot 30 at the end far from the electric lifting rod 4. One end of the first rotating shaft 33 close to the flipping plate 31 is connected to the flipping plate 31. Second rotating shafts 36 are embedded and installed on both side walls of the fourth slots 34. One end of the second rotating shaft 36 close to the fixing frame 35 is connected to the fixing frame 35. Third rotating shafts 38 are embedded and installed on both side walls of the fifth slot 37. One end of the third rotating shaft 38 close to the laser detection head 32 is connected to the laser detection head 32. The flipping plate 31 is driven to rotate by the first rotating shaft 33. Combining the preset-angle rotation of the fixing frame 35 driven by the second rotating shaft 36 and the preset-angle rotation of the laser detection head 32 driven by the third rotating shaft 38, through this operation method, the system can detect the misalignment of the magnetic steel of different types of motors, increasing the functional applicability of the system.

[0042] As a technical optimization solution of the present invention, the cleaning mechanism includes an arc-shaped block 6. A cleaning brush is provided on the side of the arc-shaped block 6 away from the support plate 5. A plurality of air outlets 29 are evenly opened at both ends of the side of the arc-shaped block 6 away from the support plate 5. An air groove 39 is opened inside the arc-shaped block 6. An air inlet 40 is penetrated and opened on the side of the arc-shaped block 6 close to the support plate 5. The air inlet 40, the air groove 39 and the air outlets 29 are communicated. The motor rotor moves close to the arc-shaped block 6. After moving to a preset position, the fan connected to the air inlet 40 starts. The wind of the fan enters the air groove 39 through the air inlet 40 and then is ejected through the air outlets 29. The second rotating motor 23 drives the lifting disc 25 to rotate, so that the motor rotor can rotate. During the rotation of the motor rotor, the motor rotor can be cleaned by blowing the motor rotor through the air outlets 29 and brushing the motor rotor with the cleaning brush on the arc-shaped block 6, ensuring the production quality of the motor rotor.

[0043] As a technical optimization solution of the present invention, a first sliding groove 7 is horizontally opened at the top of the fixed base 1 along the length direction. A first electric slider 8 is installed at the bottom of the movable disk 2, and the first electric slider 8 is slidably installed inside the first sliding groove 7. By sliding the first electric slider 8 in the first sliding groove 7, the movable disk 2 can be moved on the fixed base 1.

[0044] As a technical optimization solution of the present invention, a second sliding groove 10 is opened at the top of the movable disk 2 near the movable plate 3. A second electric slider 11 is installed at the bottom of the movable plate 3, and the second electric slider 11 is slidably installed inside the second sliding groove 10. By sliding the second electric slider 11 in the second sliding groove 10, the movable plate 3 can be moved on the movable disk 2.

[0045] As a technical optimization solution of the present invention, the auxiliary mechanism includes an abutting block 12. A lifting sliding groove 20 is vertically opened on one side of the movable plate 3 close to the center of the movable disk 2. A lifting slider 21 is slidably installed inside the lifting sliding groove 20. A first slot 15 is opened on one side of the abutting block 12 close to the movable plate 3. A movable block 16 is slidably installed inside the first slot 15. A support rod 17 is installed at the top end of the inner wall of the first slot 15. The bottom of the support rod 17 abuts against the top of the movable block 16. A telescopic connecting rod 18 is installed at the bottom of the movable block 16. A pressure sensor 19 is installed at the bottom end of the inner wall of the first slot 15. The bottom of the telescopic connecting rod 18 abuts against the top of the pressure sensor 19. One side of the lifting slider 21 close to the abutting block 12 is connected to the movable block 16. When the clamping plate 14 moves above the top of the motor rotor magnet, the abutting block 12 moves downward by sliding the lifting slider 21 in the lifting sliding groove 20. When the top of the clamping plate 14 abuts against the top of the magnet, the abutting block 12 continues to move downward. As the abutting block 12 moves downward, the movable block 16 slides downward inside the first slot 15. The movable block 16 squeezes the telescopic connecting rod 18, and the telescopic connecting rod 18 squeezes the pressure sensor 19. The pressure sensor 19 transmits the measured pressure value to the background control system. The abutting block 12 continues to press down until the pressure value measured by the pressure sensor 19 reaches the preset pressure value. During this period, the change of the magnet is observed through a camera. By this operation method, the installation stability of the magnet can be detected; the abutting block 12 moves to the preset height position of the motor rotor magnet, and then the magnet is fixed by the abutting block 12 against the magnet. The magnet sheath installation machine starts to sleeve the magnet sheath on the outside of the motor rotor. By this operation method, it can be prevented that when the magnet sheath is sleeved on the motor rotor, the magnet on the outside of the motor rotor is displaced during the downward sleeving of the magnet sheath, affecting the production quality of the motor.

[0046] As a technical optimization solution of the present invention, an electric push rod 13 is installed at the bottom of the abutting block 12. The telescopic end of the electric push rod 13 is away from the movable plate 3, and a clamping plate 14 is installed at the telescopic end of the electric push rod 13. The electric push rod 13 can drive the clamping plate 14 to move.

[0047] As a technical optimization solution of the present invention, the fixing mechanism includes a lifting disc 25 and a fixing plate 28. A second slotted groove 22 is opened at the center of the top of the movable disc 2. A second rotary motor 23 is installed at the bottom of the second slotted groove 22. The output end of the second rotary motor 23 faces upward. An electric telescopic rod 24 is installed at the output end of the second rotary motor 23. The telescopic end of the electric telescopic rod 24 faces upward. A lifting disc 25 is installed at the telescopic end of the electric telescopic rod 24. A plurality of moving sliding grooves 26 are evenly opened at the top of the lifting disc 25. A moving slider 27 is slidably installed inside the moving sliding groove 26. A fixing plate 28 is installed at the top of the moving slider 27. By the sliding of the moving slider 27 in the moving sliding groove 26, the fixing plate 28 can be driven to move, so as to complete the clamping and fixing of the motor rotor shaft. The lifting disc 25 can be driven to rotate by the second rotary motor 23, and the lifting disc 25 can be driven to lift by the electric telescopic rod 24.

[0048] When the present invention is in use, all the driving devices used in this system are electric driving devices, and all the electric driving devices used in this system are powered by connecting to an external power supply or an internal power supply through wires, etc. In this system, the electrical equipment in the system is controlled by setting a background control system. A magnetic steel sheath installation machine is provided above one end of the fixed base 1 close to the electric lifting rod 4. The magnetic steel sheath installation machine is a mature existing technology, so no more elaboration will be made on it. A feeding manipulator is provided above one end of the fixed base 1 close to the electric lifting rod 4. Two discharging manipulators are provided above the other end of the fixed base 1 away from the electric lifting rod 4, one is a qualified product discharging manipulator and the other is an unqualified product discharging manipulator. The feeding manipulator and the discharging manipulator are both mature existing technologies, so no more elaboration will be made on them. The laser detection head 32 is a mature existing technology, so no more elaboration will be made on its specific working form and principle. Cameras are installed on both sides of the electric push rod 13 at the bottom of the abutting block 12. The air inlet 40 is connected to a preset fan outside the system through a flexible conduit (which can be a conduit made of rubber or plastic), and the reserved length of the flexible conduit is sufficient for the support plate 5 to move.

[0049] When multiple motors are required for magnet misalignment detection, the feeding manipulator clamps the motor rotor with the magnet attached above the fixed base 1. Subsequently, the movable plate 2 moves below the feeding manipulator through the sliding of the first electric slider 8 in the first chute 7. The feeding manipulator lowers the clamped motor rotor. At the same time, the electric telescopic rod 24 drives the lifting plate 25 to rise. After the lifting plate 25 rises to the preset height position and stops rising, the bottom of the rotating shaft of the motor rotor abuts against the top of the lifting plate 25. Subsequently, through the sliding of the moving slider 27 in the moving chute 26, multiple fixing plates 28 move closer to the rotating shaft of the motor rotor. By clamping the rotating shaft of the motor rotor with the fixing plates 28, the system completes the fixation of the motor rotor. Subsequently, the feeding manipulator makes a reset movement away from the fixed base 1;

[0050] The lifting plate 25 continues to rise until the top of the lifting plate 25 rises above the top of the movable plate 3. The electric lifting rod 4 drives the support plate 5 to rise until the bottom of the support plate 5 rises above the top of the motor rotor. Subsequently, the first rotating motor 9 drives the electric lifting rod 4 to rotate, causing the support plate 5 to rotate above the motor rotor. Subsequently, through the second rotating shaft 36, the fixed frame 35 is driven to rotate by a preset angle, and in combination with the third rotating shaft 38, the laser detection head 32 is driven to rotate by a preset angle, enabling the laser detection head 32 to detect the inclination angle of the magnet on the motor rotor. Through this operation method, the magnet misalignment detection of the motor can be completed; when the motor needs to perform magnet misalignment detection on the side of the magnet, at this time, the first rotating shaft 33 drives the turning plate 31 to rotate, causing the turning plate 31 to make a downward turning movement until it turns to the preset state. Through this operation method, the system can detect the magnets of different types of motors, increasing the functional applicability of the system.

[0051] After the misalignment detection of the motor magnets is completed, the unqualified motor rotors are directly moved to the lower part of the unqualified blanking manipulator through the movable plate 2, and then the blanking of the unqualified products is completed through the grasping of this manipulator; after the misalignment detection of the motor magnets is qualified, the lifting plate 25 descends until the top of the lifting plate 25 descends to the position where it is at the same horizontal height as the top of the movable plate 2. At this time, through the sliding of the second electric slider 11 in the second chute 10, the movable plate 3 moves closer to the motor rotor until the movable plate 3 moves to the preset position. Subsequently, the electric push rod 13 drives the clamping plate 14 to move closer to the motor rotor. When the clamping plate 14 moves to the preset position, at this time, the clamping plate 14 is located above the top of the motor rotor magnets. Through the sliding of the lifting slider 21 in the lifting chute 20, the abutting block 12 moves downward. When the top of the clamping plate 14 abuts against the top of the magnets, the abutting block 12 continues to move downward. As the abutting block 12 moves downward, the movable block 16 slides downward inside the first slot 15. The movable block 16 squeezes the telescopic connecting rod 18, and the telescopic connecting rod 18 squeezes the pressure sensor 19. The pressure sensor 19 transmits the measured pressure value to the background control system. The abutting block 12 continues to press down until the pressure value measured by the pressure sensor 19 reaches the preset pressure value. During this period, the change of the magnets is observed through the camera. Through this operation method, the installation stability of the magnets can be detected.

[0052] After the detection of the installation stability of the magnets is qualified, the movable plate 2 moves away from the electric lifting rod 4 until the motor rotor moves out from under the arc-shaped block 6. Subsequently, the motor rotor is driven to rise by the lifting plate 25 until the bottom of the motor rotor rises above the top of the movable plate 3. Then, the electric lifting rod 4 drives the support plate 5 to lift and lower, so that the bottom of the arc-shaped block 6 is at the same horizontal plane as the bottom of the motor rotor. At this time, the movable plate 2 drives the motor rotor to move closer to the arc-shaped block 6. After moving to the preset position, the fan connected to the air inlet 40 starts. The air of the fan enters the air groove 39 through the air inlet 40 and then is ejected through the air outlet 29. The second rotating motor 23 drives the lifting plate 25 to rotate, so that the motor rotor can rotate. During the rotation of the motor rotor, by blowing air on the motor rotor through the air outlet 29 and brushing the motor rotor with the cleaning brush on the arc-shaped block 6, the motor rotor can be cleaned, ensuring the production quality of the motor rotor.

[0053] After the motor rotor is cleaned, the first rotating motor 9 drives the electric lifting rod 4 to rotate, so that the electric lifting rod 4 moves to Figure 1In the state shown, the movable disk 2 then moves below the magnet sheath installation machine, and the lifting disk 25 drives the motor rotor to descend to a preset position. At this time, the abutting block 12 moves to the preset height position of the magnet of the motor rotor. Subsequently, the magnet is fixed by abutting the magnet with the abutting block 12. The magnet sheath installation machine starts to sleeved the magnet sheath on the outside of the motor rotor. By this operation method, it can prevent the magnet on the outside of the motor rotor from shifting during the process of sleeving and installing the magnet sheath downward, which affects the production quality of the motor. During this process, the movable plate 3 moves away from the motor rotor, and then the abutting block 12 moves downward, so that the abutting block 12 can abut and fix different positions of the magnet, increasing the convenience of use of the system.

[0054] After the magnet sheath is installed, the movable disk 2 drives the motor rotor to move below the qualified product blanking manipulator. Subsequently, the lifting disk 25 drives the motor rotor to rise to a preset height position, and the qualified product blanking manipulator completes the blanking of the motor rotor; when detecting the installation stability of the magnet and the misalignment of the magnet, if one of them is unqualified, it can be directly transferred to the unqualified blanking manipulator for blanking. By this operation method, the classification blanking of qualified products and unqualified products can be completed, increasing the convenience of use of the system.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
