[0002] During the production and processing of the motor, magnets need to be installed around the rotor, and when installing the magnets on the disc motor, it is necessary to ensure that the magnets are installed 7.5° offset from the center of the rotor to ensure that the motor has optimal performance.

In the process of the rotation of the motor rotor, the motor rotor can be cleaned by blowing air to the motor rotor through the air outlet 29 and brushing the motor rotor by the cleaning brush on the arc block 6, thereby ensuring the production quality of the motor rotor.

[0043] As a technical optimization solution of the present invention, a first slide groove 7 is horizontally opened at the top of the fixed base 1 along the length direction, and a first electric slider 8 is installed at the bottom of the movable disk 2. The first electric slider 8 is slidably installed inside the first slide groove 7.

When the top of the clamping plate 14 abuts the top of the magnet, the abutment block 12 continues to move downward. As the abutment block 12 moves downward, the movable block 16 slides downward inside the first slot 15, and the movable block 16 squeezes the telescopic connecting rod 18. 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 abutment block 12 continues to press down until the pressure sensor 1 9 The measured pressure value reaches the preset pressure value. During this period, the change of the magnetic steel is observed by the camera. Through this operation mode, the installation stability of the magnetic steel can be detected; the abutment block 12 moves to the preset height position of the motor rotor magnetic steel, and then the abutment block 12 abuts the magnetic steel to fix the magnetic steel, and the magnetic steel sheath installation machine starts to sleeve the magnetic steel sheath on the outside of the motor rotor. Through this operation mode, it can be prevented that when the motor rotor is sleeved and installed with the magnetic steel sheath, the magnetic steel on the outside of the motor rotor is shifted during the process of the magnetic steel sheath being sleeved downward, thereby 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 abutment 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 clamping plate 14 can be driven to move by the electric push rod 13.

[0047] As a technical optimization solution of the present invention, the fixing mechanism includes a lifting plate 25 and a fixed plate 28.

The telescopic end of the electric telescopic rod 24 faces upward. The lifting plate 25 is installed at the telescopic end of the electric telescopic rod 24. A plurality of moving slides 26 are evenly provided on the top of the lifting plate 25. A moving slider 27 is installed inside the moving slide 26 for sliding movement. A fixed plate 28 is installed on the top of the moving slider 27. The sliding of the moving slider 27 in the moving slide 26 can drive the fixed plate 28 to move, thereby completing the clamping and fixing of the motor rotor shaft. The lifting plate 25 can be driven to rotate by the second rotating motor 23, and the lifting plate 25 can be driven to rise and fall by the electric telescopic rod 24.

[0048] When the present invention is in use, the driving devices used in the system are all electric driving devices, and the electric driving devices used in the system are all powered by wires, external power supplies or built-in power supplies. In the system, the electrical equipment in the system is controlled by setting a background control system. The fixed base 1 is provided with a magnetic steel sheath installation machine above one end close to the electric lifting rod 4. The magnetic steel sheath installation machine is an existing mature technology, so it will not be elaborated on in detail. The fixed base 1 is provided with a loading manipulator above one end close to the electric lifting rod 4. The fixed base 1 is provided with a loading manipulator above one end close to the electric lifting rod 4. Two unloading robots are provided above one end, one is a unloading robot for qualified products and the other is a unloading robot for unqualified products. Both the loading robot and the unloading robot are existing mature technologies, so they will not be elaborated in detail. The laser detection head 32 is an existing mature technology, so its specific working form and principle will not be elaborated in detail. Cameras are installed on both sides of the electric push rod 13 at the bottom of the abutment block 12, and 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 needed to detect the misalignment of magnetic steel, the loading robot clamps the motor rotor with the magnetic steel attached to the top of the fixed base 1, and then the movable plate 2 is moved to the bottom of the loading robot by the sliding of the first electric slider 8 in the first slide groove 7. The loading robot lowers the clamped motor rotor. At the same time, the electric telescopic rod 24 drives the lifting plate 25 to rise. The lifting plate 25 stops rising after rising to a preset height position. At this time, the bottom of the motor rotor shaft abuts the top of the lifting plate 25, and then the sliding of the moving slider 27 in the moving slide groove 26 makes the multiple fixed plates 28 move close to the motor rotor shaft. The fixed plates 28 clamp the motor rotor shaft to complete the system's fixation of the motor rotor, and then the loading robot performs 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, and 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, and then the first rotating motor 9 drives the electric lifting rod 4 to rotate, so that the support plate 5 rotates to the top of the motor rotor, and then drives the fixed frame 35 to rotate at a preset angle through the second rotating shaft 36, and drives the laser detection head 32 to rotate at a preset angle in combination with the third rotating shaft 38, so that the laser detection head 32 can perform inclination detection on the magnetic steel on the motor rotor. Through this operation mode, the magnetic steel misalignment detection of the motor can be completed; when the motor needs to perform magnetic steel misalignment detection on the side of the magnetic steel, at this time, the first rotating shaft 33 drives the flip plate 31 to rotate, so that the flip plate 31 flips downward until it flips to a preset state. Through this operation mode, the system can detect the magnetic steel of different types of motors, thereby increasing the functional applicability of the system.

[0051] After the motor's magnetic steel misalignment detection is completed, the motor rotor that fails the detection is directly moved to the bottom of the unqualified unloading robot through the movable plate 2, and then the unqualified product is grabbed by the robot to complete the unloading of the unqualified product; after the motor magnetic steel misalignment detection is qualified, the lifting plate 25 is lowered until the top of the lifting plate 25 drops to a position at the same horizontal height as the top of the movable plate 2. At this time, the second electric slider 11 slides in the second slide groove 10, so that the movable plate 3 moves close to the motor rotor until the movable plate 3 moves to the preset position, and then the electric push rod 13 drives the clamping plate 14 to move close to the motor rotor. When the clamping plate 14 moves to the preset position, the clamping plate 14 is located at the top of the motor rotor magnetic steel. Above the part, the lifting slider 21 slides in the lifting slot 20 to make the abutment block 12 move downward. When the top of the clamping plate 14 abuts the top of the magnetic steel, the abutment block 12 continues to move downward. As the abutment 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 abutment 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 changes of the magnetic steel are observed by the camera. Through this operation method, the installation stability of the magnetic steel can be detected.

[0052] After the magnetic steel installation stability test is qualified, the movable disk 2 moves away from the electric lifting rod 4 until the motor rotor moves out from under the arc block 6, and then the motor rotor is driven to rise by the lifting disk 25 until the bottom of the motor rotor rises above the top of the movable plate 3, and then the support plate 5 is driven to rise and fall by the electric lifting rod 4, so that the bottom of the arc block 6 and the bottom of the motor rotor are in the same horizontal plane. At this time, the movable disk 2 drives the motor rotor to move close to the arc block 6. After moving to the preset position, the fan connected to the air inlet 40 is started, and the wind 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 disk 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 air to the motor rotor through the air outlet 29 and brushing the motor rotor with the cleaning brush on the arc block 6, thereby ensuring the production quality of the motor rotor.

[0053] After the motor rotor is cleaned, the electric lifting rod 4 is driven to rotate by the first rotating motor 9, so that the electric lifting rod 4 moves to Figure 1The movable plate 2 then moves to the bottom of the magnetic steel sheath installation machine, and the lifting plate 25 drives the motor rotor to descend to the preset position. At this time, the abutment block 12 moves to the preset height position of the motor rotor magnetic steel, and then the abutment block 12 abuts the magnetic steel to fix the magnetic steel, and the magnetic steel sheath installation machine begins to sleeve the magnetic steel sheath on the outside of the motor rotor. Through this operation method, it can be prevented that when the motor rotor is sleeved and installed with the magnetic steel sheath, the magnetic steel on the outside of the motor rotor is shifted during the process of the magnetic steel sheath being sleeved downward, thereby affecting the production quality of the motor. In this process, the movable plate 3 is moved away from the motor rotor, and then the abutment block 12 moves downward, so that the abutment block 12 can abut and fix different positions of the magnetic steel, thereby increasing the convenience of using the system.

[0054] After the magnetic steel sheath is installed, the movable plate 2 drives the motor rotor to move to the bottom of the qualified product unloading robot, and then the lifting plate 25 drives the motor rotor to rise to the preset height position, and the qualified product unloading robot completes the unloading of the motor rotor; during the magnetic steel installation stability detection and the magnetic steel misalignment detection, if one of the two is unqualified, it can be directly transferred to the unqualified unloading robot for unloading. Through this operation method, the classified unloading of qualified and unqualified products can be completed, which increases the convenience of using the system.
