Description

Technical Field

[0001] The invention belongs to the technical field of magnetic winding equipment, and in particular relates to an automatic wire feeding and hanging device of a magnetic winding machine. Background Art

[0002] Electromagnetic components are widely used in various fields and are inevitably often used in various types of electronic products. Therefore, the quality of their production is closely related to the service life and quality of the electronic products.

[0003] The magnetic ring winding process of the inductor coil is generally completed by a winding machine. Wire storage and wire winding are very critical steps. At present, the wire storage and wire winding on the winding machine are manually hung with holes on the wire storage ring. The wire winding is also manually hung on the wire hanging groove of the side slider, which is very inconvenient to operate and tests the proficiency of the operator, which is not conducive to the automation of the entire process.

[0004] In order to solve the above problems, the invention patent with application number 201611093584.7 discloses a fully automatic wire hanging device for a magnetic winding machine, wherein the wire storage ring of the fully automatic wire hanging device is provided with a wire storage hanging port and a side slider, and the side slider is provided with a winding hanging port. When the wire needs to be stored and hung, the copper wire is pressed against the edge of the wire storage ring, and then the wire storage ring driving device is started to rotate the wire storage ring in the opposite direction of the opening of the wire storage hanging port, so that the copper wire can be hung tightly in the wire storage hanging port; when the wire needs to be wound and hung, the copper wire is pressed against the winding hanging port, and then the copper wire is further folded and pushed to complete the winding and hanging. Such a device can realize fully automatic wire hanging and improve production efficiency. However, such a fully automatic wire hanging device also has the following problems: first, the wire is hung by the wire winding hanging mouth on the side slider for winding, and the wire hanging force is relatively small, which is only suitable for the winding of thin wires, but not for the winding of thick wires; second, the existence of the side slider makes the positioning requirements of the magnetic ring when it is put on the wire storage ring higher, and it is easy to cause inaccurate positioning and cause collision between the side slider and the magnetic ring.
