Embodiment 1

[0025] combined reference Figure 1~3 As shown, the method for preventing large-area exposure of the insulating frame provided by Embodiment 1 of the present invention specifically includes: setting several mold positioning bumps (not shown) protruding along its radial direction in the plastic sealing mold (not shown), Before plastic sealing, the stator assembly 100 is placed in the plastic sealing mold, and the mold positioning projections are pressed against the stator winding end insulating frame 1 along the radial direction of the plastic sealing mold, so that the mold positioning projections can be insulated from the stator winding end The abutting fit of the frame 1 prevents the large-area exposure of the insulating frame 1 at the end of the stator winding after plastic sealing, and after the plastic sealing is completed, a number of positioning points are formed on the plastic sealing shell 200 to match the positioning protrusions of each mold on the plastic sealing mold...

Embodiment 2

[0042] combined reference Figure 4 As shown, the method for preventing the large-area exposure of the insulating frame provided by the second embodiment of the present invention is as follows: on the insulating frame 1 at the end of the stator winding, a number of frame positioning protrusions 10 protruding along its radial direction are provided, and before plastic sealing, The stator assembly 100 is placed in the plastic sealing mold, and the frame positioning projection 10 is pressed against the plastic sealing mold along the radial direction of the plastic sealing mold, so that the stator winding end after plastic sealing can be prevented from The phenomenon that the external insulating frame 1 is exposed in a large area occurs. The method for preventing the large-area exposure of the insulating frame provided in this embodiment is to set the frame positioning protrusion 10 on the insulating frame 1 at the end of the stator winding, so that in the process of molding the p...

Abstract

The invention is applicable to the field of motors, and discloses a method for preventing large-area exposure of the insulating frame: setting a plurality of mold positioning projections protruding along the radial direction in the plastic sealing mold, and placing the stator assembly in the plastic sealing mold before plastic sealing. And the mold positioning projections are pressed against the insulating frame at the end of the stator winding along the radial direction of the plastic sealing mold, so that the insulation frame at the end of the stator winding after plastic sealing can be prevented from being enlarged by the cooperation between the positioning projections of the mold and the insulating frame at the end of the stator winding. The phenomenon of exposed area occurs, which improves the aesthetics of the product and the production pass rate.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a method for preventing large-area exposure of an insulating frame. Background technique [0002] After the stator winding is wound on the stator core, it generally has two axial ends protruding from both ends of the stator core along the axial direction of the motor. In the traditional technology, the fixing and insulation treatment of the axial ends of the stator winding The method is as follows: first use tape and cotton yarn to bind and fix the axial end of the stator winding, and then perform insulating varnish treatment. This treatment method has complex procedures, cumbersome operations, and long production cycles in specific applications. Defects of automated production operations and high labor costs. [0003] In order to overcome the defects of the above-mentioned traditional technologies, relevant technical personnel proposed a scheme to realize the insulation treatment of the a...
