Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", and the like indicate an azimuth or a positional relationship based on the azimuth or the positional relationship shown in the drawings, or the azimuth or the positional relationship in which the inventive product is conventionally put in use, it is merely for convenience of describing the present invention and simplifying the description, and it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus it should not be construed as limiting the present invention.
Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.
As disclosed in the background art, in the prior art, in the process of winding an electric core, after the winding of the electric core is completed, the pole piece needs to be cut off, at this time, the head part and the tail part of the pole piece can be formed, the head part of the pole piece needs to reenter the winding mechanism 170 to wind a new electric core, and because the conventional feeding roller group, namely the related mechanism, is obliquely arranged, the movement path of the pole piece is downwards deflected due to gravity, the head part of the pole piece can collide against the roller, at this time, the position of the positive pole piece needs to be stopped and swung, the pole piece is damaged, the auxiliary time is definitely increased, and the efficiency is influenced.
Further, the conventional pole piece feeding scheme includes two actions:
before the pole piece is fed, the head of the pole piece moves obliquely downwards by inertia after passing through a deviation correcting mechanism and falls on a diaphragm on a passing roller to enter a winding area together with the diaphragm.
Action two: after the pole piece and the diaphragm enter the winding area together, a winding needle on the equipment starts winding the core.
When the pole piece is in action, after passing out of the deviation correcting mechanism, the head of the pole piece keeps the original motion state by inertia, but the motion path of the pole piece is downwards deflected due to the gravity factor, so that the head of the pole piece can collide against the passing roller, the position of the positive pole piece needs to be stopped and the pole piece is damaged.
