Varnish dipping device of stator coil winding

The present disclosure relates to a varnish impregnation device comprising: a lower housing in which a stator is seated in an interior space, the stator comprising a stator core having a plurality of teeth projecting inward or outward and having slots as spaces between the teeth, an upper insulator and a lower insulator, and a coil winding; the upper insulator and the lower insulator are respectively connected with the upper part and the lower part of the stator core, and the coil winding passes through the slots and is wound around the teeth; a lower sealing portion coupled with a lower portion of the inner space of the stator seated in the inner space of the lower housing; a central sealing portion on the lower sealing portion; an upper sealing portion on the central sealing portion; a first cover member coupled with an upper portion of the upper sealing portion and an inner upper portion of the upper insulator; and a second cover member coupled with an upper outer portion of the stator core and an outer pe
