Problems solved by technology

[0004] However, since the upper platen and the glue liquid plane required for the glue filling in the above-mentioned patent are in contact with each other and both are parallel to the horizontal plane, the highest surface where the gas floats with the glue as the matrix is ​​the upper platen and the glue liquid plane required for the glue filling. On the contact surface of the obtained glue liquid plane, it is difficult to ensure that the gas in the glue liquid floats up to the position corresponding to the exhaust port so that the gas is discharged from the exhaust port, and part of the gas that has not floated up to the position corresponding to the exhaust port may remain On the contact surface between the upper platen and the glue liquid plane required for glue filling, the exhaust is not complete, which affects the performance of the finished product
Especially for hydrogen energy motors, the working environment is usually immersed in water for a long time. The water resistance and impermeability of the motor stator after sealing with glue are relatively high. When the gas bubbles burst, the stator coils may be exposed, which may cause damage to the hydrogen energy motor operating in water and affect the operating efficiency.

Embodiment 1

[0035] like figure 1 and image 3 As shown, this embodiment provides a glue-filling mold for a motor stator 1. The glue-filling mold includes an upper mold 2 and a lower mold 3. When the motor stator 1 is fixed between the upper mold 2 and the lower mold 3, the upper mold 2 and the lower mold The mold 3 is formed with a cavity 4 for pouring glue on the motor stator 1 , and the motor stator 1 is located in the cavity 4 . The shape of the upper mold 2 and the lower mold 3 and the motor shape are preferably disc-shaped, and in order to ensure the separation of the glue and the mold during glue filling and demolding, it is preferable to use PTFE (polytetrafluoroethylene) material to make the mold , or apply a release agent on the contact surfaces of the upper mold 2 and the lower mold 3 near the cavity 4 or the upper mold 2 and the lower mold 3 and the glue to form a mold release layer (not shown in the figure) before the glue is poured. , such as silicone grease, to ensure that...

Embodiment 2

[0050] This embodiment provides a method for pouring glue into the stator 1 of a motor, and the method includes:

[0051] 1. Glue preparation steps:

[0052] The pre-prepared glue solution is decompressed and defoamed, and after the decompression and deaeration treatment, the glue solution is kept warm for later use.

[0053] Specifically, the glue solution is put into a vacuum oven for decompression and defoaming, the oven temperature is 60° C., the vacuum degree is ≧ 0.09 MPa, and the processing time is 15 to 30 minutes. When the temperature increases, the viscosity of the glue will decrease relatively, and the fluidity will increase, so that the gas existing in the glue can be foamed and discharged in advance, and the glue with less gas foaming rate can be provided for the subsequent glue filling.

[0054] 2. Mold preparation:

[0055] Firstly, the motor stator 1 is placed in the cavity 4 after the lower mold 3 and the lower mold 3 are closed, and the upper mold 2 and the...

Abstract

The invention discloses a motor stator glue pouring mold and a method thereof, and relates to the technical field of motor sealing, the mold comprises an upper mold and a lower mold, a cavity used for carrying out glue pouring on a motor stator is formed between the upper mold and the lower mold, and the upper mold is provided with an exhaust port and a glue injection port which are communicated with the cavity; during glue filling, the exhaust port corresponds to the highest point of the glue filling glue surface of the motor stator in the height direction, so that gas bubbles in glue liquid can float to the highest point in the height direction and are discharged from the exhaust port corresponding to the highest point, and the gas bubbles are discharged to the maximum extent; and the integrity of glue filling forming and the working performance of subsequent motor operation are ensured.

Description

technical field [0001] The invention relates to the technical field of motor encapsulation, in particular to a motor stator glue filling mold and a method thereof. Background technique [0002] The motor stator mainly includes three parts: coil winding, stator core and frame. The main function of the stator is to generate a rotating magnetic field, so that the rotor is cut by magnetic lines of force in the rotating magnetic field to generate or output current. The existing method of potting the motor stator is usually potting from one end of the stator, and the potting glue is immersed in the gap of the stator assembly, thereby improving the moisture resistance of the stator, and improving the protection level, electrical strength, mechanical strength and service life of the stator. [0003] The existing Chinese invention patent with the publication number CN104868667B discloses a motor stator winding glue filling mold. During the pressure filling process, the air in the inn...
