Abstract

PURPOSE:To form a coil having high space factor by constructing to wind the coil from outside toward inside while urging the coil to the inner periphery of a winding jig, thereby eliminating the expansion of the coil toward the outside. CONSTITUTION:A magnet wire 7 is pulled out from the ed of a flier 4, wound on a pressing jig corresponding to an arm 21, the arm 21 is moved by the tension of a compression coil spring 23, and a magnet wire 7 which is wound on the jig is urged to the deep wall surface 13a of a winding jig 13. Then, when a motor is energized to rotate the flier 4 around the jig 13, the wire 7 is fed out of the flier 4 to be wound around four pressing jigs 18. Thus, the wire is wound and superposed in the prescribed number from outside to inside of the coil by the guiding action of the arm 21 to the magnet, and sequentially densely wound by the jig 18 toward the inner periphery.

Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to a coil μ winding device used for an armature coil or the like of a V-ya μ gap type motor. [Technical Background of the Invention] The armature of the μ-gap cage-I is constructed by radially disposing coils wound around a printed circuit board. The winding device of the carp μ has a structure in which a magnet wire is wound around the outer periphery of a substantially trapezoidal bobbin to form a substantially trapezoidal wire. [Problems with the background art] The starting part of the magnet wire is wound along the bobbin shape, but as the number of turns increases, the outer periphery of the coil swells, resulting in a trapezoidal coil with each side bulging outward in an arc. That's it. For this reason, when the coil μ is arranged on a printed circuit board, the positions of the coils must be taken into consideration so that each side of the coil does not interfere with each other, which makes the work extremely troublesome. Furthermore, the magnet wire of the carp μ is in a loose state due to bulge, and there is a problem that the space factor of the carp μ is low. [Object of the Invention] The object of the present invention is to provide a winding device that can wind a carp without causing a bulge on the outer side of the carp. Through the cooperative action of a pressing jig that forces the wire to follow the inner circumference of the winding jig and a guide mechanism that guides the magnet wire to a predetermined position within the winding jig,
It is characterized by winding the carp /&/ from the outer circumference toward the inner circumference. [Embodiment of the Invention] An embodiment of the present invention will be described below with reference to Figures wi1 to 3WJ. Reference numeral 1 denotes the main body of the winding device, on which a hollow shaft 2t driven by a motor is supported, and a rod-shaped wire 4 is eccentrically attached to a circle s13 fixed to the tip of the hollow shaft 2, and a magnet is attached. A gloss supply mechanism 5 is configured. A hollow boss body 6 is fixed to the center of the disk 5,

This is a fixed shaft supported through a bearing 11 at the center of the shaft, which is connected to an appropriate stationary part by a connecting rod 12 so that it remains stationary even when the boss body 6 rotates.

[It is configured to keep. Reference numeral 13 denotes a winding jig, which is formed in the shape of a bottomed cylinder having a substantially trapezoidal shape, for example, and this winding jig 13i
Insert into fixed shaft 10 and screw 1 through shaft 14'j.
5, the tightening is fixed. 16 and 17 are large diameter cylinders 16a, respectively. 17& and small diameter 16b, 17b are extendable and retractable and are made up of 94 sets of long side and short side support cylinders, and these supports 1i116.17t - l inside of the winding jig 15.
! Two sets of each are arranged in pairs so as to face the I angle and fixed to the large diameter cylinder 166117ak cap 14, and a round bar-shaped pressing jig 1 is attached to the tip of the small diameter cylinders 16b and 17b.
8ffi[i! d is fixed. A compression coil μ spring 19 as an elastic body is housed in the supports 11i16 and 17, and is biased toward the angle 1sK of the pressing oil JNBt winding jig 13. Reference numeral 20 denotes an index section, which includes an arm 21t-[which is configured to move the arm 21 in the axial direction and in the radial direction from one corner of the winding jig 15 toward the center by an index mechanism (not shown); This constitutes a guide mechanism 22t. The arm 21 is biased by a compression coil and a spring 23 in the direction of the arrow mark, that is, from the open end side of the winding jig 13 toward the back wall surface 15a side, and always has a flat guide portion 21a1 at the tip.
It is located between one corner of the winding jig 13 and the corresponding pressing jig 18. Next, the operation of the above configuration will be explained. The arm 21 is moved in the opposite direction of the arrow 23 against the spring force of the compression coil spring 23, and in this state, the magnet wire 7t is pulled out from the tip of the wire 4 to create a suppression jig corresponding to the arm 21. After that, the arm 21 is moved in the direction of the arrow P by the spring force of the compression coil μ spring 23, and the arm 21 is wound around the pressing jig. Next, when the motor is energized and the wire winding jig 150 is rotated, the magnet wire 7 is drawn out from the wire winding jig 150 and the four pressing jig 1
It is wound around 8 times. In this case, magnet wire 7
Each time the arm 21 is wound once, the magnet wire 7 is pressed in the direction of the arrow M by the spring force of the compression coil spring 23 while moving intermittently in the direction opposite to the direction of the arrow M. The winding oil AI SC) is sequentially wound around the circumference 9 of the member 18 from the back toward the open end side, and the wound magnet wire 7 is coated with the winding oil X15 by the compression coil spring 19. The winding jig 130 is pressed against the scrap wall surfaces 1 and 5b by the pressing jig 18 which is biased toward the corner of the wire. When winding of the outermost circumference of the coil is completed in this manner, the arm 21 moves by a predetermined pitch in the direction of arrow B, and the compression coil moves in the direction of arrow M by the spring force of the spring 23, so that the magnet wire 71 The second winding is performed from the outermost part of the %t) which was previously wound. Afterwards, the guide action of the arm 210 on the magnet wire 7 causes the second winding to be carried out from the outside to the innermost part of the magnet wire 7. The material is wound in layers 11 a predetermined number of times, and is sequentially pressed against the inner periphery of the previously wound material by a pressing jig 18 to tightly wind it. ] After completing μ, blow hot air onto the carp μ or energize the carp μ to generate heat, and pre-coat the magnet wire 7 with heat-sensitive adhesive [After fusion, cooling and solidification, screw 151 Loosen the cap 14 and remove it together with the support tubes 16 and 17 and the pressing jig 18, and remove the coil tube winding jig 13.
Take it out from inside. The thus formed carp μC has an outer shape as shown in FIG. 5 as a winding jig 1! It matches the shape of the inner circumferential wall surface 15b of S, and there is no bulge on each side. Therefore, when arranging the carps μ on a printed circuit board, the carps μ can be placed with a margin between each other, which makes the work easier, unlike the conventional method in which there is a risk that the bulges may interfere with each other. And the space t created by the disappearance of the bulge
If - is also utilized, the amount of winding t-◆ can be reduced, and a higher output product t can be manufactured without increasing the size. Furthermore, since the space factor of the carp μ is improved, copper loss is reduced and operational efficiency is improved. It should be noted that the winding jig does not need to be formed into a cylindrical shape, and may be constructed from four frames 24 in an abbreviated shape that are provided corresponding to the four corners as shown in FIG. Further, the shape of the winding jig is not limited to the trapezoidal shape, but can be changed to various shapes according to the required external shape of the carp μ. 11! In the above embodiment, a total of four arms 21 may be provided, corresponding to each pressing jig 18KM. [Off @O effect] As is clear from the above description, the present invention has a structure in which the carp μ is pressed against the inner periphery of the winding jig and wound from the outside to the inside, so that the carp μ is It has an excellent effect of being able to form a carp that does not bulge outward and has a high space factor.
