Description

Auxiliary winder for annular coil

The utility model relates to the device of coiling, particularly a kind of auxiliary bobbin winoler with toroidal electric component that is used in.

Tradition has toroidal electric component such as transformer and inductor, wherein the number of turn of coil is often up to thousands digit, and before automatic coil winding machine is not asked the city as yet, just can finish one the man-hour (manually) that the winding operation of this kind coil all needed to spend about one day, therefore, have a strong impact on the efficient that produces, more limited the progress of industry, ask that until a kind of exploitation of automatic coil winding machine afterwards the city has just improved this disappearance a little;

Loop coil is essential one deck insulating material that coats before the coiling enamelled wire, early stage system is to twine adhesive tape as the insulation material, now then replace with mass-produced insulating cover, this kind insulating cover is two symmetries and the ring that can coat annular core, but use discovery still to have inconvenience through reality, so that toroidal winding efficiency is still desirable not to the utmost, and its reason can be described as follows with reference to the toroidal circle line layout of commonly using shown in the accompanying drawing 1:

First the end of a thread 1 of coil is after winding operation is finished; to be covered by the circle line pressure of follow-up winding; cause first line end to depart from the phenomenon of initial point; returning traces it to its cause is just the end of a thread 1 and is not located when tap; so that the circle line is when intact one encircles (i.e. 360 degree) and gets back to starting point; the circle line of follow-up stack will be overlaid on a part of line body of the end of a thread 1 just successively; eventually to the phenomenon that causes multiple spot heavily to cover and be offset; this kind coil goods still can be accepted in safety regulations not tight domestic; but in industrial advanced country such as Germany; the U.S. etc. then never allow; because; the phenomenon that this a kind of multiple spot heavily covers will easily cause short circuit risk and influence its useful life; in view of this; the solution of dealer when producing now; it is the active configuration mode of a people one machine; and at the circle line whenever when a full ring when spending (promptly 360); the temporary transient shutdown again of automatic coil winding machine crossed the end of a thread 1 just with artificial with the follow-up enamel-cover tape that will twine; again start coiling then; though this measure can be got rid of aforesaid shortcoming, under this interrupted operational scenario of shutting down, influence the efficient of its winding operation also.

The purpose of this utility model; to provide a kind of exactly and both can guarantee the coil quality; can once start shooting again and just finish the auxiliary bobbin winoler of omnidistance winding operation; the auxiliary bobbin winoler of this kind will provide the positioning reference of the end of a thread just; and follow-up circle line is when being circulated back to the anchor point of this first the end of a thread; should assist bobbin winoler also can guide enamelled wire to slip over automatically and become entangled in the first the end of a thread of fixing a point on the auxiliary bobbin winoler; the another side of the end of a thread twines operation with the circle line that continues next circulation and move to just; the traditional work of forgoing fully need be shut down and with the artificial practice of crossing line, be increased the speed that produces.

The technical solution of the utility model is as follows: a kind of toroidal auxiliary bobbin winoler, particularly a kind of being used in has toroidal electric component, as transformer, the auxiliary bobbin winoler of iron cores such as inductor, system is made up of the insulating cover that two symmetries are coating annular core, and especially, wherein an insulating cover is being parallel on the axis direction of its annular core, outwards be extruded with an outlet stator, the height of this outlet stator fixes on winding operation finish after just and the contour condition of circle line; The edge crestal line of this outlet stator is the slick and sly shape that can slip over smoothly for enamelled wire, to form a kind of coil benchmark of wire jumper when the setting element of the end of a thread and automatic winding just.According to embodiment of the present utility model, this outlet stator can be coniform or square, triangle.

The utlity model has following advantage: 1. because the design of outlet stator makes that just the end of a thread can be positioned a certain fixed point, the not displacement that enamelled wire affects that can be repeated to twine in winding process; 2. owing to the slick and sly crestal line of outlet stator, first the end of a thread can be crossed easily and do not fractureed, and winding operation can be accomplished without any letup, and has improved winding efficiency, and has guaranteed the coil part quality.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, and be described in further detail:
