Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of coil impregnation, in particular, to an impregnation device for motor production. BACKGROUND

[0002] Motor coils are one of the main components of a motor, and are usually made of insulated wires. For example, a plurality of motor coils are usually wound on a stator, and the plurality of coils are arranged and connected according to certain rules to form a winding. During the operation of the motor, a magnetic field is generated around the coil when current passes through the coil, and this magnetic field interacts with the magnetic field generated by the stator or other coils to drive the rotor to move.

[0003] The motor coil is made of a plurality of wires (enameled wires). Since there are small gaps between the wires, between the coil and the slot wall of the core, and between the layers, the motor coil needs to be impregnated to improve the insulation strength, eliminate air gaps, and increase the mechanical strength and rigidity of the motor coil.

[0004] In the prior art, when impregnating the motor coil, the moisture and low molecular volatile substances inside the motor coil are first removed by baking to allow the insulation paint to penetrate better. Then, the motor coil is cooled to the required impregnation temperature (usually set to 50°C to 80°C) of the insulation paint, and then the pre-baking cooled motor coil is immersed in a paint tank containing insulation paint for a period of time. In this process, the insulation paint penetrates into the motor coil through capillary action. Alternatively, the motor coil can be placed in a sealed impregnation tank, and then the impregnation tank is evacuated to a vacuum state to extract the air and residual volatile substances inside the motor coil. Then, the pressure is maintained for a period of time to ensure sufficient penetration. After impregnation, the motor coil is left to stand for a period of time to allow the excess paint to naturally drip off, and then the impregnated motor coil is placed in an oven for drying.

The output ends of the nozzles 26 are downwardly inclined. The supply part is installed on the oil immersion cylinder 1 and used for supplying the insulating paint to the arc-shaped pipes 24.

[0041] Specifically, after the stator winding is placed in position, the insulating paint can be poured into the oil immersion area 101. At this time, the relative positions between the extension cylinders 25 and the discharge cylinders 23 are adjusted according to the size of the stator winding, and then fixed after being adjusted to the appropriate positions.

[0046] The working principle or use process of the present application is: When the stator winding is immersed in paint, first, the moisture and low molecular volatile substances inside the stator winding are removed by baking, so that the insulating paint can better penetrate, and after baking is completed, the pre-baking cooled stator winding is placed in the oil immersion area 101 by hoisting until the outer side of the stator part of the stator winding abuts against the supporting roller 7 and the driving roller 8, at this time the stator winding is located at the center position of the bearing frame 6, then the positions between the sliding frame 18 and the slide rail 17 on both sides are adjusted respectively, and the vertical position of the positioning frame 19 on the sliding frame 18 is adjusted until the positioning wheel 20 at the end of the positioning frame 19 abuts against the end of the stator part in the stator winding, then the positioning screw 22 is screwed into the positioning nut 21 on the side of the sliding frame 18 through the positioning nut 21 and the positioning screw 22, until the tail of the positioning screw 22 abuts against the slide rail 17, that is, the relative position between the slide rail 17 and the sliding frame 18 is fixed, and the positioning screw 22 is screwed into the positioning nut 21 on the side of the positioning frame 19, until the tail of the positioning screw 22 abuts against the slide rail 18, that is, the relative position between the slide rail 18 and the positioning frame 19 is fixed, thereby preventing the stator winding from shifting during the immersion in paint, thereby affecting the immersion in paint.

[0047] After the stator winding is placed in position, the insulating paint can be poured into the oil immersion area 101, at this time the relative position between the extension cylinder 25 and the discharge cylinder 23 is adjusted according to the size of the stator winding, and after adjustment to the appropriate position, the relative position between the extension cylinder 25 and the discharge cylinder 23 is fixed, at this time the two second valves 35 are closed, the two first valves 34 are opened, and then the first water pump 27 is opened, the first water pump 27 draws the insulating paint in the oil storage tank 3 through the first water inlet pipe 29, and then sends it into the arc-shaped pipe 24 through the first water outlet pipe 30, the insulating paint entering the arc-shaped pipe 24 enters the two discharge cylinders 23 respectively, and then enters the corresponding extension cylinders 25, at this time the spray head 26 is opened, the insulating paint entering the extension cylinder 25 is discharged, and the output end of the spray head 26 is inclined downward, and the discharged insulating paint is sprayed on both ends of the stator winding.

[0048] Meanwhile, the driving motor 10 is started, the driving motor 10 drives the driving gear 9 to rotate, the driving gear 9 drives the driven gear 11 to rotate, with the rotation of the driven gear 11, the driven gear 11 drives the transmission shaft 14 to rotate, the transmission shaft 14 drives the driving bevel gear 15 to rotate, thereby driving the driven bevel gear 13 to rotate, that is, the driving roller 8 is driven to rotate, through the setting of the anti-skid pattern 16, the possibility of the support roller 7 and the driving roller 8 slipping with the stator winding in the rotating process is reduced, thereby driving the stator winding to rotate through the rotation of the driving roller 8, with the rotation of the stator winding, the insulating paint is uniformly sprayed on the coil of the stator winding, the stator winding is fully contacted with the insulating paint, thereby improving the penetration efficiency of the insulating paint, until the insulating paint is immersed in the whole stator winding, the insulating paint is stopped to be discharged, when the insulating paint is not needed to be supplied, the first water pump 27 is closed, and the two first valves 34 are closed.

[0049] The driving member 4 is driven to move the vacuum cover 2 to the closed position, the oil immersion area 101 forms a closed space, at this time, the driving part is closed, then the vacuumizing equipment is connected with the joint on the vacuum cover 2, then the oil immersion area 101 is vacuumized, thereby the air and residual volatile matters in the motor coil are extracted, then the pressure is kept for a period of time to ensure the full penetration, the insulating paint is penetrated into the stator winding, after a period of time, the insulating paint is fully penetrated into the stator winding, then the pressure is released and the vacuum cover 2 is opened, at this time, the two second valves 35 are opened, and the two first valves 34 are in the closed state, then the second water pump 28 is started, through the setting of the second water inlet pipe 33, the insulating paint in the oil immersion area 101 is sent into the filter 32 to be filtered, then the filtered insulating paint is sent back to the oil storage tank 3 through the second water outlet pipe 31, then the stator winding is taken out through the hoisting equipment, then a period of time is kept to let the excess paint naturally drop, then the stator winding is put into the oven to dry the motor coil after the insulating paint is immersed, thereby the insulating paint process is completed.
