Method and device for winding core wire

The present invention relates to a method and apparatus for winding a wire, and more particularly to a method and apparatus for winding a wire of iron core on a core portion having a flange portion between two flange portions.

Generally, when the wire is wound around the core portion between the flange portions of the iron core, the wire is usually inserted into the flange portion of the wire end when the wire is wound, and the wire is first fixed by spot welding on the wire. After the upper flange portion of the electrode, a predetermined number of winding wires are wound on the core portion, and then the other end of the wire is spot-welded to the electrode on the other end of the outlet end flange portion to complete the core. The winding of the wire, the winding method of the iron core is generally referred to as "spinning"; the other winding method uses the wire to enter the flange portion of the wire end, and the wire is first wounded by a predetermined number of turns. The winding wire is wound on the core portion, and then the two ends of the wire are spot-welded and fixed to the electrode on the flange portion to complete the winding of the wire on the iron core. The winding method of the iron core is generally called "opposite winding". A type of iron core wire winding adopts a "shun" mode, for example, the publication No. 201501149 "coil winding method and device", which is used to place the iron core on a fixed jaw when it is fed into the fixture. A movable jaw is clamped and used to hang on the fixture The wire body provides the wire to be wound around, so that the wire passes through a certain path, especially through the electrode on the flange portion of the iron core, and the electrode on the spot welding head can be used from the top to the bottom corresponding to the wire passing through the electrode. Welding; a type of iron core wire winding adopts the "wrap-around" mode. For example, in the case of the coil and coil manufacturing method and device disclosed in No. 201445597, the wire of the second wire is completed after the winding of the wire on the iron core is completed. The end is simultaneously folded and folded on the electrode on the end face of the flange portion on the same side, and the wire end of the two wire is welded to the electrode on the end face of the flange portion on the same side by means of dipping.

For example, in the prior art, the core wire winding of the publication No. 201445597 adopts the "wrap-around" mode, and only the upper end of the flange end face of the wire which is simultaneously folded and folded on the same side can be applied, and then the soldering method is used. The wire end of the two wire is welded to the electrode on the end face of the flange portion on the same side, but the core of the SMD (surface-adhesive) inductor is wound, and since the electrode on the end face of the flange portion must be directly attached to the surface of the substrate, The wire end of the two wire is located on the end face of the flange portion on the same side, which will increase the height of the iron core attached to the surface of the substrate, which is disadvantageous to the requirement of lightness, thinness and shortness, and thus the current winding method of the core wire.

In the method and apparatus for winding a wire of a core according to an embodiment of the present invention, the feeding step of the loading station is to sandwich the core A toward the front end of the first jaw 13 in the Y-axis direction of the first flange portion A2 toward the front. 131 is pushed, and the pushing mechanism G is driven by the pushing member G1 from the other side of the pinch 131 with respect to the blocking portion 137, and the vertical direction of the left side of the first flange portion A2 of the core A is shifted in the X-axis direction. The side edge A22 causes the vertical side edge A22 of the right side of the first flange portion A2 of the core A to abut against the abutting portion 137, so that the core A can be located between the pressing portion 133, the drill portion 134, and the blocking portion 137. The clamping port 131 is effectively and accurately positioned; in addition, the winding member B is wound around the second clamping jaw 14 and the top shaft K1 is abutted against the front clamping jaw 131 of the first clamping jaw 13 before the winding. The end face A31 of the second flange portion A3 of the iron core A can be used to hold the wire B and prevent the core A from being separated from the front end opening 131 of the first jaw 13 by the winding, and the wire B is held by the winding K2 Performing an obliquely moving operation, on the one hand, the wire B is moved into the jaw 141 to be clamped, and on the other hand, the wire wound by the predetermined number of turns is properly tightened; and the winding K2 is replaced. In the step of moving the clamping, the cutting member H1 is driven to obliquely advance the trimming line, so that the core A completes the wire winding and fixes the first wire end B1 and the second wire end B2 on both sides of the first jaw 13 The second clamping jaws 14 are used to weld the first wire end B1 and the second wire end B2 to the two sides of the end face A31 of the second flange portion A3 of the core A and the main electrode portion. A32 is parallel and is bent on the side electrode portion A34 of the side edge A33 of the ninety degree turn.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
