Description

Technical Field

[0002] Nano rare earth material is a material with special structure and properties, and its grain size is at the nanometer level. Compared with traditional materials, nano rare earth materials have a higher surface area and more grain boundaries, which give them better electromagnetic properties and thermal stability. Therefore, nano rare earth material ironless disc motor can achieve higher power density and efficiency. Nano rare earth material ironless disc motor adopts a disc structure, which has a smaller size and lighter weight than traditional iron core motors. This makes nano rare earth material ironless disc motor have greater advantages in space-constrained occasions, such as in drones, machinery production, medical equipment and other fields.

[0003] In order to make the manufactured motors achieve the preset functions, it is necessary to conduct sampling tests after the motors are manufactured to simulate various actual working conditions, so as to efficiently and accurately verify and test the actual performance of the motors.

In the process of the moving plate 11 moving away from the motor, the sliding block 28 slides inside the fixed block 20 and squeezes the telescopic rod 27. The telescopic rod 27 squeezes the pressure sensor 26. The pressure sensor 26 transmits the pressure value to the background control system.

[0044] When the present invention is in use, the equipment used in the device is all electric drive equipment, and the electrical equipment in the device is powered by connecting the power supply through a wire. The electrical equipment in the device is controlled by setting a control system in the device. The opening 4 is connected to the air pump preset outside the device through a conduit, and a control valve is provided at the connection between the opening 4 and the conduit. The top of the protective cover 2 is sealed by the top cover 3. Three manipulators are preset on the upper outer side of the protective cover 2, one of which is a loading manipulator, and the other two are good product unloading manipulators and defective product unloading manipulators. The manipulator is an existing mature technology, so it will not be described in detail. The bottom of the top cover 3 is provided with lighting equipment and a camera to record the test process. The speed sensor 24, temperature sensor 39, air pressure sensor 40 and sound sensor 41 used in the device are all existing mature technologies, so it will not be described in detail.

The structure proposed by the motor reduces the use of rare earth materials of the permanent magnet motor, reduces the loss of no-load back electromotive force before and after demagnetization, and improves the anti-demagnetization performance of the motor.

[0045] When the device is in use, the electric lifting rod 43 drives the top cover 3 to extend upward to a preset height position, and the rotating motor 44 drives the top cover 3 to rotate to a preset position, so that the top cover 3 will not affect the use of the preset manipulator outside the device, and then the two clamping rods 9 slide to the preset position through the first electric slider 8 in the first slide groove 7, and then the feeding manipulator lowers the clamped motor.

The motor output shaft drives the roller 22 to rotate during the rotation process, and the rotation of the roller 22 drives the connecting shaft 23 to rotate synchronously, and then the speed sensor 24 detects the speed of the connecting shaft 23, and transmits the detected speed value to the background control system. The speed detection of the motor is completed through this operation method.

[0047] When the motor speed is detected, the vibration generated by the motor output shaft will be transmitted to the movable rod 19 through the roller 22, and the movable rod 19 will shake inside the first slot 29. When the movable rod 19 shakes, the vibration sensor 33 detects the shaking value of the movable rod 19 and transmits it to the background control system, and then the rotating motor 18 drives the rotating rod 17 to rotate, so that the rotating rod 17 rotates to a vertical state with the connecting rod 16, and then the sliding of the telescopic slider 36 in the telescopic slide groove 35 drives the telescopic block 31 to move toward the inside of the third slot 34, until the roller 22 moves to the inside of the third slot 34, and then through The up and down movement of the lifting slider 15 in the lifting slide groove 14 combined with the movement of the movable plate 11 allows the end of the movable rod 19 to abut against multiple positions of the motor. At this time, when the motor is in use, the vibration generated outside the motor can be detected by the vibration sensor 33, and the vibration value is transmitted to the background control system for comparison. This operation method can complete the vibration detection of the motor; by rotating the motor 18 to drive the rotating rod 17 to rotate in different directions, combined with the movement of the movable plate 11 in the protective cover 2, the device can perform vibration detection on both sides of the motor. This operation method can increase the accuracy of the detection results of the device.

[0048] The rotating rod 17 rotates to the side of the fixed block 20 facing the motor output shaft, and the connecting rod 16 is extended by the electric extension rod 25, so that the two clamping blocks 21 abut against the outside of the motor output shaft, and then the moving plate 11 moves away from the motor. In the process of the moving plate 11 moving away from the motor, the sliding block 28 slides inside the fixed block 20 and squeezes the telescopic rod 27. The telescopic rod 27 squeezes the pressure sensor 26. The pressure sensor 26 transmits the pressure value to the background control system. The moving plate 11 continues to move until the measured pressure value reaches the preset pressure value. During this period, the changes in the motor output shaft are observed. Through this operation method, the tensile strength of the motor output shaft can be tested.

[0049] During the process of testing the motor, the temperature sensor 39 can detect the temperature of the motor when it is running, and by increasing the rated voltage of the motor to make the motor run under load, and then detecting the temperature of the motor, the temperature rise test of the motor can be completed; the sound sensor 41 can detect the noise when the motor is running, the air pump connected to the opening 4 is started, and the interior of the protective cover 2 is inflated and pressurized, the air pressure sensor 40 can detect the pressure inside the protective cover 2, and when the pressure value inside the protective cover 2 reaches the preset value, the valve installed at the opening 4 is closed, and the state of the motor running under the preset air pressure is observed at this time, and the above-mentioned vibration detection, speed detection and other functional detection of the motor are performed, and compared with the values ​​detected under normal working conditions. Through this operation method, the running state of the motor under high pressure environment can be completed.

[0050] Start the heating plate 6, and the inside of the protective cover 2 can be heated by the heating plate 6. At this time, the temperature inside the protective cover 2 can be detected by the temperature sensor 39. In the process of the heating plate 6 heating the inside of the protective cover 2, the clamping rod 9 drives the motor to move left and right, so that the temperature inside the protective cover 2 can be more uniform, and the heating effect of the heating plate 6 is increased. When the temperature inside the protective cover 2 rises to the preset temperature, the above-mentioned multiple function tests are performed on the motor, and the test results are compared with the test data during normal operation. Through this operation method, the high-temperature working state of the motor can be detected.

[0051] After the detection is completed, the top cover 3 moves upward to the preset position, and then the air pump connected to the opening 4 is started. At this time, the air pump quickly inflates the inside of the protective cover 2, so that the hot air inside the protective cover 2 can be quickly discharged, and the motor and various equipment in the device can be quickly cooled down, thereby increasing the convenience of using the device.

[0052] When the device is unloading the motor, the motor that has passed the inspection is moved to the bottom of the good product unloading robot through the clamping rod 9 for unloading, and the motor that has failed the inspection is moved to the bottom of the defective product unloading robot through the clamping rod 9 for unloading. This operation method can complete the classified unloading of the motor, increasing the convenience of using the device.
