[0027] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0028] Reference will be made below to Figures 1 - 4 Describe the motor stator curing device 100 according to an embodiment of the present invention, and a potting system including the above-mentioned motor stator curing device 100 is also proposed.

[0029] The stator to be cured can be a high-speed permanent magnet motor stator. The high-speed permanent magnet motor stator needs to be potted. After the potting adhesive is poured into the stator, the potting adhesive is cured by the motor stator curing device 100 to realize the cured stator after potting.

[0030] The motor stator curing device 100 includes: a box body 11. A plurality of mutually independent curing cavities 13 are arranged in the box body 11, and the curing cavities 13 can accommodate the stator to be cured. That is to say, a plurality of openings are formed in the box body 11 to form the curing cavities 13. The curing cavities 13 have a certain depth so that the potted stator can be placed in the curing cavities 13, and the potted stator can enter the curing cavities 13 from the openings of the curing cavities 13.

[0031] Among them, the number of the curing cavities 13 can be three, four, five or six. The number of the curing cavities 13 is selected according to the size of the box body 11 and the size of the stator to be cured.

[0032] In an example of the present utility model, there are four curing chambers 13, and the four curing chambers 13 are respectively arranged in two layers, with two curing chambers 13 arranged at intervals in each layer. Four cured stators can be placed in the four curing chambers 13 respectively.

[0033] The motor stator curing device 100 includes: a plurality of heating modules 21, and the plurality of heating modules 21 are respectively arranged in the plurality of curing chambers 13 for heating the curing chambers 13. That is to say, one heating module 21 can be arranged in each curing chamber 13, and the heating module 21 can be a heating furnace. The heating module 21 can heat the curing chamber 13 to keep the curing chamber 13 at a certain temperature for curing the potted stator.

[0034] As Figure 3 shown, the motor stator curing device 100 includes: a plurality of control modules 22, and the plurality of control modules 22 are respectively electrically connected to the plurality of heating modules 21. The control module 22 is used to control the corresponding heating module 21 to heat the curing chamber 13. Specifically, each curing chamber 13 is electrically connected to the corresponding control module 22, and the control module 22 respectively controls the corresponding heating module 21 to operate to heat the curing chamber 13, so as to complete the curing of the stator to be cured. The plurality of curing chambers 13 can realize separate curing and separate control, which can reduce power consumption, save energy and reduce emissions; reduce production man-hours and improve production efficiency; reduce the floor area of the motor stator curing device 100.

[0035] A control screen, control buttons, switch buttons, etc. are also arranged on the box body 11. The control screen can realize visual operation to improve convenience; the control buttons and switch buttons are convenient for operators to operate.

[0036] Therefore, the plurality of curing chambers 13 can accommodate a plurality of stators, and the heating module 21 in any one of the curing chambers 13 is independently controlled by the corresponding control module 22, and a plurality of stators can be cured simultaneously or successively, improving the efficiency of stator curing.

[0037] Among them, the stator to be cured is a potted stator.

[0038] As Figure 1 shown, a sliding member 14 is arranged in the curing chamber 13, and the sliding member 14 is slidably connected to the stator to be cured so that the stator to be cured slides in the front-rear direction. Specifically, the front side in the front-rear direction corresponds to the outside of the curing chamber 13, and the rear side in the front-rear direction corresponds to the inside of the curing chamber 13. By being slidably connected to the sliding member 14, the stator to be cured can slide in the curing chamber 13 in the front-rear direction, so that the stator to be cured can smoothly enter the curing chamber 13. The sliding member 14 can be a slide rail, and the stator to be cured is slidably matched with the slide rail to realize the sliding of the stator to be cured in the front-rear direction, facilitating the entry and exit of the stator to be cured from the curing chamber 13.

[0039] According toFigure 1 As shown, a limiting member 15 is disposed in any curing chamber 13. The limiting member 15 is disposed inside the sliding member 14 and is used to limit the stator to be cured. Specifically, the stator to be cured moves along the sliding member 14 towards the inside of the curing chamber 13 until the stator to be cured abuts against the limiting member 15. The limiting member 15 limits the stator to be cured, so that there are gaps between the stator to be cured and the inner walls of the curing chamber 13.

[0040] In some embodiments, the motor stator curing device 100 further includes: a plurality of position sensors respectively disposed at the limiting members 15 in the plurality of curing chambers 13, and the plurality of position sensors are respectively electrically connected to the plurality of control modules 22; when the stator to be cured abuts against any one of the limiting members 15, the corresponding control module 22 controls the heating module 21 to start to heat the curing chamber 13. Specifically, the position sensor in any one of the curing chambers 13 is disposed at the limiting member 15, and the position sensor is electrically connected to the corresponding control module 22. After the stator to be cured enters the curing chamber 13, when the stator to be cured abuts against the limiting member 15, the position sensor can transmit a signal to the control module 22, and the control module 22 can drive the chamber door 12 to close and simultaneously turn on the heating module 21 to heat the curing chamber 13 to cure the stator to be cured.

[0041] As Figure 3 shown, the motor stator curing device 100 further includes: a plurality of chamber doors 12, the plurality of chamber doors 12 respectively correspond to the plurality of curing chambers 13 one by one and are hinged to the box body 11, and the plurality of chamber doors 12 are respectively electrically connected to the control module 22. Specifically, the plurality of chamber doors 12 respectively cover the openings of the plurality of curing chambers 13, and the chamber door 12 is hinged to the box body 11 so that the chamber door 12 can rotate relative to the box body 11. Any chamber door 12 is electrically connected to the corresponding control module 22. After the stator curing is completed, the control module 22 drives the chamber door 12 to open so as to move the stator out of the motor stator curing device 100 and enter the next process.

[0042] In some other embodiments, a detector may be disposed on the chamber door 12, and the detector is electrically connected to the corresponding control module 22. When there is no stator to be cured in the curing chamber 13, the detector can detect the conveying device. If the detector detects that a conveying device is approaching, the control module 22 drives the chamber door 12 to rotate to open the curing chamber 13. After the conveying device is aligned with the motor stator curing device 100, the conveying device pushes the stator to be cured into the curing chamber 13; when the stator to be cured abuts against the limiting member 15, the position sensor transmits a signal to the corresponding control module 22, and the control module 22 drives the chamber door 12 to close.

[0043] As Figure 1As shown, a temperature sensor 17 is provided in any curing chamber 13, and the temperature sensor 17 is electrically connected to the corresponding control module 22. Specifically, the temperature sensor 17 measures the temperature in the curing chamber 13. The corresponding control module 22 is electrically connected to the temperature sensor 17. The temperature sensor 17 transmits the acquired temperature signal to the control module 22, and the control module 22 controls the operation of the heating module 21 according to the temperature signal.

[0044] Specifically, a target temperature is preset in advance. The motor stator curing device 100 includes: a heating stage, a heat preservation stage, and a cooling stage. In the heating stage, the heating module 21 operates, and the temperature in the curing chamber 13 continuously rises until the temperature in the curing chamber 13 is equal to the target temperature. In the heat preservation stage, the temperature in the curing chamber 13 is maintained at the target temperature to cure the stator to be cured. In the cooling stage, the heating module 21 stops operating, and the temperature in the curing chamber 13 gradually drops to cool the cured stator to be cured.

[0045] Heating stage: When the temperature value acquired by the temperature sensor 17 is less than the target temperature, the heating module 21 heats until the temperature value acquired by the temperature sensor 17 is equal to the target temperature.

[0046] Heat preservation stage: When the temperature value acquired by the temperature sensor 17 is equal to the target temperature, the heating module 21 stops heating. When the temperature value acquired by the temperature sensor 17 is less than the target temperature, the heating module 21 heats. Keep the temperature in the curing chamber 13 at the target temperature. At this time, the potting glue of the stator to be cured begins to cure.

[0047] Cooling stage: When the potting glue of the stator is cured, the control module 22 controls the heating module 21 to stop operating to cool down the stator.

[0048] In some embodiments, the control module 22 may include: a time relay, and a target heat preservation time is preset. When the heat preservation time reaches the target heat preservation time, the control module 22 controls the heating module 21 to stop to cool the cured stator to be cured.

[0049] As Figure 1 shown, a blower 16 is provided in any curing chamber 13. The blower 16 is connected to the box body 11, and the blower 16 is electrically connected to the corresponding control module 22. Specifically, a blower 16 is provided in each curing chamber 13. The blower 16 is connected to the box body 11, and the blower 16 is disposed opposite to the opening. The blower 16 is electrically connected to the corresponding control module 22. The corresponding control module 22 controls the operation of the blower 16, and the blower 16 can evenly mix the gas in the curing chamber 13 to ensure that the temperature in the curing chamber 13 is uniform.

[0050] In some embodiments, the inner wall of any curing chamber 13 is coated with a heat-insulating member. The heat-insulating member can be heat-insulating sponge, which can reduce the heat dissipation to the outside and ensure the heating effect and heat-insulating effect of the heating module 21.

[0051] Combined with Figures 1 - 4 As shown, the potting system includes: a potting device, a motor stator curing device 100, and a conveying device. The potting device is used to inject potting glue into the stator to be potted; the motor stator curing device 100 is used to heat and cure the potted stator; the conveying device is used to convey the stator potted by the potting device to the motor stator curing device 100.

[0052] The potting device injects potting glue into the stator to be potted, and the inside of the potting device maintains a vacuum state to ensure that the potting glue can fully penetrate into the object to be potted, improving the potting quality; the conveying device transports the potted stator (i.e., the stator to be cured) to the motor stator curing device 100; the stator to be cured enters the curing chamber 13, and the control module 22 controls the heating module 21 to heat. After the stator is cured, the conveying device moves the stator out of the curing chamber 13 and into the next process.

[0053] Combined with Figure 2 As shown, a first clamping portion is provided on the conveying device, and a second clamping portion 111 is provided at the opening of the curing chamber 13. The first clamping portion and the second clamping portion 111 are clamped and connected so that the potted stator enters the curing chamber 13 from the conveying device. That is to say, before the stator to be cured enters the curing chamber 13, the first clamping portion and the second clamping portion 111 are clamped and connected to complete the alignment of the conveying device and the motor stator curing device 100, so that the stator can smoothly enter the curing chamber 13. After the stator is cured, the control module 22 drives the box door 12 to open, the first clamping portion and the second clamping portion 111 are clamped and connected, and the alignment of the conveying device and the motor stator curing device 100 is completed, so that the stator can smoothly move out of the curing chamber 13 and into the next process.
