Description

Technical Field

[0002] With the rapid development of intelligent manufacturing technology, the current level of social automation is steadily improving. The demand for key power motor components in automation design is growing rapidly, and the demand for different types of motors is also growing rapidly. Both the output and type of motors are showing a rapid growth trend.

[0003] The rotor and stator are the two most important structures in the motor; the rotor generally includes the rotor and the rotor winding, wherein the rotor core is formed by stacking rotor stampings, and the rotor winding is arranged on the rotor core; the rotor stampings need to be fixed after stacking to form a complete rotor core, and the stacking uniformity of the rotor stampings and the firmness of the fixing of the rotor stampings will affect the overall performance of the rotor.

[0004] The viscose cores that appear on the market, especially the viscose cores for new energy vehicle drive motors, are formed by forming multiple iron core sheets using production equipment, and using the viscose coated on the surface of the iron core sheets in advance to make the multiple iron core sheets bonded to each other to form the viscose core. Generally, the viscose is cured by auxiliary electromagnetic induction heating during production. However, when applying the viscose, it is necessary to use a dispersed multiple glue point coating, and have multiple glue spraying ports. When this type of glue spraying mechanism is set on a narrow tooth part for glue spraying, the glue amount is difficult to control, and glue overflow is prone to occur. In addition, since the in-mold auxiliary heating curing requires a large amount of electrical energy consumption, and it is necessary to wait for a period of time before the viscose curing can be realized, the production efficiency is low and the electrical energy consumption is large.

[0045] The reversing mechanism includes a second motor 11 and a reversing shaft 12. The second motor 11 is fixedly mounted on the top surface of the equipment base 1. The reversing shaft 12 is connected to the top surface of the output end of the second motor 11. Reversing side plates 13 are fixedly mounted on the outer two side surfaces of the reversing shaft 12. The processing station 2 is fixedly mounted on the end surface of the reversing side plate 13.

[0046] The limiting mechanism includes a limiting plug shaft 15 and a control component. A plurality of through long grooves 14 are opened on the top surface of the processing station 2. The limiting plug shaft 15 is movably connected to the inner wall of the through long groove 14. A magnet block 16 is fixedly provided on the bottom surface of the limiting plug shaft 15. A reset spring 17 is commonly connected between the magnet block 16 and the through long groove 14. A movable cavity 18 is opened inside the processing station 2, and the control component is fixedly provided on the inner wall of the movable cavity 18.

[0047] The control component includes a third motor 19 and a swing shaft 21. The third motor 19 is fixed to the inner wall of the movable cavity 18. A rotating shaft 20 is fixed to the outer surface of the output end of the third motor 19. One end of a plurality of swing shafts 21 is connected to the outer surface of the rotating shaft 20, and the other end of the swing shaft 21 is connected to a magnetic block 22.

[0048] The cooling circulation mechanism includes a cooling channel 23 and a preheating channel 24, which are respectively fixed on the top surface of the equipment base 1, and a circulation pipe 25 is commonly connected between the cooling channel 23 and the preheating channel 24. An air cooler 26 is fixed on the bottom surface of the equipment base 1, and a cold air delivery pipe 27 is connected to the outer surface of the output end of the air cooler 26, and the end surface of the cold air delivery pipe 27 is connected to the inside of the cooling channel 23. The outer surface of the input end of the air cooler 26 is connected to the hot air delivery pipe 28, and the end surface of the hot air delivery pipe 28 is connected to the inside of the preheating channel 24.

[0049] An annular groove is formed on the bottom surface of the equipment support 3, and a plurality of guide shafts 29 are evenly distributed on the top surface of the glue injection turntable 6. The end surface of the guide shaft 29 is movably connected to the inner wall of the annular groove.

[0050] Here’s how it works:

[0051] When in use, the starting point of the processing station 2 is the processing loading and unloading point, the iron core monoliths to be processed are placed on the processing station 2 one by one, and the limiting plug shaft 15 is adapted to the opening on the iron core monolith, and then the iron core monolith is fixed, and the reversing shaft 12 is driven to rotate by the second motor 11. At this time, the processing station 2 rotates along the top of the preheating channel 24 to the bottom of the coating mechanism, and the iron core monolith on the processing station 2 is preheated through the preheating channel 24 to prepare for uniform coating;

[0052] After the processing station 2 moves to the bottom of the coating mechanism, it is stationary. At this time, the glue discharging pressure system is controlled by the glue coating control system to extrude the glue in the glue storage tank 7 from the glue discharging nozzle 8 to the surface of the iron core monolithic sheet. The second motor 11 drives the glue injection turntable 6 to rotate, so that the glue is evenly coated on the surface of the iron core monolithic sheet. At the same time, the coating scraper 10 is driven to rotate along the surface of the iron core monolithic sheet to evenly coat the glue. The limiting plug shaft 15 passes through the notch 30 to ensure that the coating scraper 10 can rotate smoothly. After the second motor 11 drives the glue injection turntable 6 to rotate one circle, the glue discharging pressure system stops discharging glue. The second motor 11 drives the glue injection turntable 6 to rotate one and a half circles and then stops rotating. The gluing process is completed to ensure that the glue is evenly coated.

[0053] The first motor 4 drives the steering shaft to rotate further, so that the processing station 2 moves along the cooling channel 23 to reach the processing and loading and unloading point. The low-temperature airflow flows in the cooling channel 23, and the iron core monolithic sheet on the processing station 2 is cooled by heat exchange to accelerate the solidification of the glue. The heated airflow in the cooling channel 23 is led out to the preheating pipeline through the circulation pipeline 25 for heat recovery and reuse, and is cooled again by the air cooler 26 and reused. The cooling effect is good, and the internal circulation is realized, which reduces air pollution.

[0054] After the processing station 2 arrives at the processing and loading and unloading point, the third motor 19 drives the rotating shaft 20 to rotate, so that the magnetic block 22 overlaps with the magnet block 16. Since the magnetic properties of the corresponding surfaces of the magnetic block 22 and the magnet block 16 are opposite, the magnet block 16 moves downward along the long groove 14 under the action of magnetic attraction, and the reset spring 17 is compressed, so that the limit plug shaft 15 retracts downward, and the glue-coated iron core single piece can be removed.

[0055] Embodiment 2:

[0056] like Figure 5 As shown, a glue coating and cooling device for processing induction heating cores of automotive motors includes a device base 1 and a glue coating control system, and the glue coating control system includes a data acquisition unit, a glue output amount estimation unit, a control unit, a feedback analysis unit, and a glue amount calibration unit;

[0059] The specific process of outputting a single glue output value is as follows:

[0060] S101, obtaining historical processing parameters and the cross-sectional area of ​​the single iron core corresponding to the historical processing parameters from a database, wherein the historical processing parameters include the rotation speed of the first motor 4, the single glue discharge value of the glue discharge pressurizing system, and the rotation speed of the second motor 11, and integrating the historical processing parameters and the corresponding cross-sectional area of ​​the single iron core into a training sample;

[0068] The specific process of generating a qualified signal or a calibration signal is as follows:

[0069] S201, obtain several sets of pressure data between the core single piece and the processing tooling, and calculate the glue coating evaluation coefficient Wi according to the following formula: Where i=1, 2, 3, ..., n, n is the number of micro-force sensors arranged at the bottom of the processing tooling, is the initial pressure data between the iron core monolithic sheet and the processing tooling before gluing, and the gluing evaluation coefficient Wi is used to reflect the distribution uniformity of the glue on the iron core monolithic sheet after gluing. The larger the gluing evaluation coefficient Wi is, the worse the gluing effect is, and vice versa, the smaller the gluing evaluation coefficient Wi is, the better the gluing effect is;

[0074] If the coating evaluation coefficient is less than the evaluation judgment threshold Wmax, the glue amount calibration trend is to reduce the glue output.

[0075] The present invention establishes a glue output prediction model according to a deep learning algorithm, and substitutes the cross-sectional area of ​​a single iron core piece to be processed into the glue output prediction model to output a single glue output value, and then adjusts the output power of the glue output pressurization system so that the extrusion amount at the glue output nozzle 8 reaches the single glue output value, calculates the glue coating evaluation coefficient according to the pressure data during the glue coating process, and judges the glue coating evaluation coefficient according to a preset glue coating standard evaluation threshold, and again obtains a new single glue output value from the glue output prediction unit, and sends the single glue output value that meets the glue amount calibration trend to the control unit for secondary glue output calibration.
