Description

Technical Field

[0001] The utility model relates to the field of devices for manufacturing coils, in particular to a rotary wire-releasing mechanism used in conjunction with a winding machine. Background Art

[0002] Film-wrapped wire is a copper wire covered by multiple layers of insulating film, while silk-wrapped wire is a copper wire covered by insulating materials such as polyamide or polyamide-imide. In the production process of flat film-wrapped wire and flat silk-wrapped wire coils, the wire is wound by a winding machine, and a pay-off mechanism is used in conjunction with the winding machine to pay off the wire. Some existing Alpha winding machines used for flat film-wrapped wire and flat silk-wrapped wire coils include a left spindle mechanism and a right spindle mechanism. The wire released by the pay-off mechanism passes through the left spindle and the wire mouth sleeve, passes around the guide wheel, and then passes around the mold core of the right spindle mechanism. The flying fork mechanism set on the left spindle rotates around the axis with the wire, so that the wire is wound on the mold core of the right spindle mechanism to form a coil. However, the existing pay-off mechanism often adopts a simple pay-off shaft structure, and the pay-off shaft can only rotate along its own axis to pay off the wire. When the flying fork mechanism rotates with the wire to wind the wire, the pay-off shaft cannot simultaneously follow the flying fork mechanism to perform corresponding rotational movement, which causes the wire wound by the winding machine to become tangled, and the tangling may cause the wire to break. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a rotating wire-releasing mechanism, which can prevent the problem of kinking of wires during the winding process.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A rotary wire-paying mechanism comprises a frame, a support plate, a rotating disk, a horizontal wire-paying frame, a wire-paying shaft and a servo motor; the support plate is vertically fixed on the frame; the rotating disk is arranged parallel to the front side of the support plate; the horizontal wire-paying frame is vertically fixed on the rotating disk; one end of the rotating shaft of the wire-paying shaft is rotatably connected to the horizontal wire-paying frame, and the axis of the wire-paying shaft is parallel to the disk surface of the rotating disk; the servo motor is fixedly connected to the rear side of the support plate, and the servo motor is used to drive the rotating disk to rotate around the axis.

[0006] In some embodiments, a magnetic brake is fixedly connected to the horizontal pay-off stand, and the magnetic brake is coaxially connected to the rotating shaft of the pay-off shaft. In at least one embodiment, the rotating shaft of the pay-off shaft passes through the horizontal pay-off stand, and the rotating shaft of the pay-off shaft and the horizontal pay-off stand are connected via a bearing; the output shaft of the magnetic brake is connected to the rotating shaft of the pay-off shaft via a coupling.

[0007] Compared with the prior art, the present invention achieves at least the following beneficial effects:

[0008] The rotating pay-off mechanism is matched with a winding machine to perform pay-off operations. The servo motor is set to the same rotation speed and direction as the flying fork mechanism of the winding machine. The servo motor is used to drive the rotating disk to rotate around the axis, and the rotating disk drives the horizontal pay-off frame and the pay-off shaft to rotate as a whole. When the winding machine is winding, the pay-off shaft rotates along its own axis for each circle of pay-off. At the same time, the rotating disk drives the horizontal pay-off frame and the pay-off shaft to rotate as a whole, and the horizontal pay-off frame and the pay-off shaft have the same rotation direction and speed as the flying fork mechanism as a whole, thereby preventing the wire from being tangled.

[0014] The present invention will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0015] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "several" and "multiple" mean two or more, unless otherwise clearly and specifically defined. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In this application, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature can include the first and second features directly contacting, or it can include the first and second features not being in direct contact but contacting through another feature between them. Moreover, the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0016] like Figures 1 to 3 As shown, in one embodiment of the utility model, the rotary pay-off mechanism includes a frame 1, a support plate 2, a rotating disk 3, a horizontal pay-off frame 4, a pay-off shaft 5 and a servo motor 6; the support plate 2 is vertically fixed on the frame 1; the rotating disk 3 is arranged parallel to the front side of the support plate 2; the horizontal pay-off frame 4 is vertically fixed on the rotating disk 3; one end of the rotating shaft of the pay-off shaft 5 is rotatably connected to the horizontal pay-off frame 4, and the axis of the pay-off shaft 5 is parallel to the disk surface of the rotating disk 3; the servo motor 6 is fixedly connected to the rear side of the support plate 2, and the servo motor 6 is used to drive the rotating disk 3 to rotate around the axis.

[0017] Furthermore, a magnetic brake 7 is fixedly connected to the horizontal pay-off frame 4, and the magnetic brake 7 is coaxially connected to the rotating shaft of the pay-off shaft 5. The magnetic brake 7 transmits a constant torque through a magnetic field, which has the effect of controlling the wire tension on the pay-off shaft 5 to stabilize the wire, so that the wire is more compact during winding. Furthermore, the rotating shaft of the pay-off shaft 5 passes through the horizontal pay-off frame 4, and the rotating shaft of the pay-off shaft 5 is connected to the horizontal pay-off frame 4 through a bearing; the output shaft of the magnetic brake 7 is connected to the rotating shaft of the pay-off shaft 5 through a coupling.

[0018] Furthermore, the output shaft of the servo motor 6 is connected to a planetary reducer 8, which is used to reduce the number of revolutions of the output shaft of the servo motor 6 to a required number of revolutions and obtain a larger torque. Specifically, a rotating main shaft 31 is provided along the axis of the rotating disk 3, and the rotating main shaft 31 passes through the support plate 2, and the rotating main shaft 31 is connected to the support plate 2 through a bearing; the output shaft of the planetary reducer 8 is connected to the rotating main shaft 31 through a coupling.

[0019] The rotating wire-paying mechanism is matched with a winding machine to perform wire-paying operations. The servo motor 6 is set to the same rotation speed and direction as the flying fork mechanism of the winding machine. The servo motor 6 drives the rotating disk 3 to rotate around the rotating main shaft 31, and the rotating disk 3 drives the horizontal wire-paying frame 4 and the wire-paying shaft 5 to rotate as a whole. When the winding machine is winding, the wire-paying shaft 5 pays off the wire. The wire-paying shaft 5 rotates along its own axis for each circle of wire-paying. At the same time, the rotating disk 3 correspondingly drives the horizontal wire-paying frame 4 and the wire-paying shaft 5 to rotate as a whole, and the horizontal wire-paying frame 4 and the wire-paying shaft 5 have the same rotation speed and direction as the flying fork mechanism as a whole, thereby preventing the wire from being tangled.

[0020] It should be understood that all the above embodiments are illustrative rather than restrictive, and any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the conception of the present invention are still within the scope of the technical solution of the present invention.
