Description
Technical Field
The invention relates to the technical field of stator potting, in particular to a vacuum glue filling method for a disc type motor stator.
Background
An axial magnetic field motor is also called a disc motor, a stator core of the axial magnetic field motor is usually formed by winding a silicon steel strip, glue permeates along a place with small resistance under the action of vacuum and capillary during potting, and because an air gap is inevitably formed between winding layers, in the current potting process, after a predetermined amount of glue is filled into the inner end and the outer end of an iron core coil by a potting machine, most of structural air bubbles generated by the glue can be extracted from an iron core groove with relatively small resistance, but one part of the structural air bubbles can be extracted from the gap between the winding layers, and the process causes that the iron core groove is difficult to be filled with the glue, and finally influences the insulation quality of a stator product.
Disclosure of Invention
In view of the above, the invention provides a vacuum glue filling method for a disc motor stator, which can avoid the problem that the iron core slot is not filled with glue, thereby effectively ensuring the insulation quality of a product.
In order to achieve the purpose, the invention provides the following technical scheme:
a vacuum glue pouring method for a disc type motor stator is characterized in that after a stator core is fixed in a containing groove of a motor shell, before pouring glue, an annular cover plate is attached to the other surface, opposite to the motor shell, of the stator core, and after the pouring glue is poured, the cover plate is taken down from the surface of the stator core.
Optionally, in the vacuum glue filling method, a circular groove is formed in one surface of the cover plate, which is used for attaching the stator core, and the depth of the groove is 2mm to 3 mm.
Alternatively, in the above vacuum potting method, after the cover plate is removed from the surface of the stator core, the potting adhesive is cured by baking.
Optionally, in the vacuum glue filling method, the cover plate is provided with a plurality of air leakage holes, plugs are installed in the air leakage holes, and before the cover plate is taken down from the surface of the stator core, the plugs are taken away from the air leakage holes, so that air can enter gaps between the cover plate and the stator core through the air leakage holes.
According to the technical scheme, the disc type motor stator vacuum glue pouring method provided by the invention has the advantages that before the pouring of the pouring glue, the annular cover plate is attached to the other surface, opposite to the motor shell, of the stator core, so that although an air gap exists between the winding layers of the stator core, the cover plate can seal and block a gap opening on the upper surface of the stator core under the vacuum action, when the pouring glue is filled, the path of air in the air gap is blocked by the cover plate, and the pouring glue cannot seep into the air gap between the winding layers during vacuumizing due to the gas resistance.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.
Fig. 1 is a schematic diagram illustrating a vacuum glue pouring method for a stator of a disc motor according to an embodiment of the present invention.
Labeled as:
1. a workpiece; 2. pouring a sealant; 3. and (7) a cover plate.
Detailed Description
For the purpose of facilitating understanding, the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, a workpiece 1 is a stator core (provided with windings) of a disc motor, it should be noted that fig. 1 omits a motor housing under the workpiece 1, not shown, the stator core is fixed in a receiving groove of the motor housing before potting adhesive, fig. 1 shows a state after the potting adhesive 2 has been filled, but before the potting adhesive 2 is filled, an annular cover plate 3 is firstly attached to an upper surface of the stator core (i.e. the other surface opposite to the motor housing), although there is an air gap between winding layers of the stator core, as can be seen from fig. 1, the cover plate 3 can seal a gap opening on the upper surface of the stator core under the vacuum action, so that when the potting adhesive 2 is filled, an outward path of air in the air gap is blocked by the cover plate 3, due to the gas resistance, the potting adhesive 2 does not seep into the air gap between the winding layers again during vacuum pumping, thereby avoiding the problem that the iron core groove is not filled with glue and effectively ensuring the insulation quality of the product.
It should be understood that after the pouring of the potting compound 2 is completed, the cover plate 3 needs to be removed from the surface of the stator core for the next use. For making apron 3 take off easily, can set up a plurality of disappointing hole on apron 3 to be equipped with the end cap for disappointing hole, the end cap is installed in disappointing hole when filling casting glue 2, and after casting glue 2 solidification, takes off the end cap from disappointing hole earlier, lets the air can enter into the gap between apron 3 and the stator core by disappointing the hole, then will be easier when taking off apron 3 from the stator core again. In specific practical application, the air release hole can be provided with an internal thread, the plug is provided with an external thread, and the plug is screwed and installed in the air release hole. It should be noted that, after the plug is installed in the air release hole, the plug should be flush with the lower surface of the cover plate 3 to ensure that the cover plate 3 can be tightly attached to the surface of the stator core.
In the vacuum potting method of the present invention, after the cover plate 3 is removed from the surface of the stator core, the potting adhesive 2 is cured by baking.
In order to better enable the pouring sealant 2 to fill the core groove, a circular groove can be formed in one surface of the cover plate 3, which is used for attaching the stator core, as shown in fig. 1, the depth of the groove is generally 2mm to 3mm, the bottom of the groove is tightly attached to the surface of the stator core, and the groove wall has a certain blocking effect on the pouring sealant 2, so that the acting force between the cover plate 3 and the pouring sealant 2 is enhanced, and the pouring sealant 2 before curing is favorably kept in the core groove.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
