Description

[Technical Field]

[0001] The present invention relates to a motor coil winding device with an expanded winding range, and more particularly to a coil winding device that can wind a large amount of wire by improving the former structure, without expanding the blade length of the upper tool that accommodates the coil. [Background technology]

[0002] Generally, an electric motor is a device that converts electrical energy into mechanical energy by using the force that a current-carrying conductor receives in a magnetic field, and generally includes the term motor.

[0003] Here, electric motors are classified into DC motors and AC motors depending on the type of power source supplied, and AC motors are again classified into three-phase AC and single-phase AC motors, but three-phase AC motors are mainly used today.

[0004] In addition, there are two methods for winding coils around the stator inside the motor: winding the coil directly onto the stator, or winding the coil in a specific shape first and then inserting it into slots formed between the teeth on the inner wall of the stator. The higher the performance of the motor, the more coils need to be wound, which creates a limit to the amount of manual labor that can be used.

[0005] Therefore, in order to wind the coils mechanically instead of manually, Korean Patent No. 10-1632361, "Motor Coil Winding Device and Method," has proposed a technical configuration that not only automates winding but also winds two polarities with one device. However, this increases the number of turns of wire that make up the core used in motor manufacturing, and manufacturing coils using existing equipment limits the length of the former on which the wire is wound, which limits the number of turns of wire that can be wound on one former.

[0006] To solve the above problems, the length of the former was extended to allow for a longer winding length of wire, thereby increasing the area on which the wire is wound. In response to this, the length of the upper tool blades that transport the wire wound on the former was also increased. However, as the length of the upper tool blades increased, the problem of the wire not being able to rest between the blades remained.

[0007] Therefore, there is a need for a method for winding a large number of wires onto a former without increasing the length of the upper tool blade and for receiving the wound wires on the upper tool. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Korean Patent Registration No. 10-1632361 Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been devised to solve the above problems, and its object is to mount a coil with an increased number of turns on the upper tool by changing the length of the bubble on which the wire is wound without changing the length of the upper tool.

[0010] In addition, the process can be carried out without changing the coil device former and upper tool depending on the type of motor being manufactured.

[0011] The objects of the present invention are not limited to the above objects, and other objects not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0012] To achieve the above object, the present invention provides a motor coil winding device for inserting a coil with an expanded wire winding range into an upper tool (U), comprising a former section (10) located above the upper tool (U) and having a multi-stage former on whose outer periphery the wire is wound; a load section (21) installed above the former section (10) and extending downward, comprising a former cylinder (20) connected to one end of the former section (10) and a length for controlling the length of the load section (21).

[0013] The former section (10) is provided with a moving former (11) that slides along a rail (12) formed on the inner surface, and the moving former (11) is connected to one side of the load section (21). The control unit contracts the load unit (21) in response to the rise of the insert tool, thereby causing the upper tool (U) to rise and seat the wire wound on the former unit (10) inside.

[0014] In addition, the maximum length of the former section (10) is longer than that of the upper tool (U).

[0015] In addition, the former section (10) is characterized by having an inclined surface on one side of the outer periphery of the former section (10) so that the wire wound on the moving former (11) is not pinched between the steps formed by the former section (10) and the moving former (11) when the moving former (11) rises.

[0016] The size of the former section (10) is larger than the size of the moving former (11), so that the moving former (11) is inserted inside the former section (10). [Effects of the Invention]

[0017] The coil winding device according to the present invention has the effect of seating a coil with an increased number of turns on the upper tool by changing the length of the former on which the wire is wound without changing the length of the upper tool. In addition, there is an advantage that the process can be carried out without changing the former and upper tool of the coil device depending on the type of motor being manufactured.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The advantages and features of the present invention, as well as methods for achieving them, will become more apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various different forms. These embodiments are provided solely to fully explain the scope of the invention and to fully convey the scope of the invention to those skilled in the art. The present invention is defined only by the scope of the claims.

[0020] The following detailed description of specific embodiments of the present invention will be given with reference to the accompanying drawings, in which the same reference numerals refer to the same elements regardless of the drawings, and "and / or" includes each and every combination of one or more of the referenced items.

[0021] Although terms such as "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are used only to distinguish one component from another. Therefore, it goes without saying that the first component referred to below may also be the second component within the technical concept of the present invention.

[0022] The terms used in this specification are for the purpose of describing the embodiments and are not intended to limit the present invention. In this specification, the singular form includes the plural form unless otherwise stated in the phrase. When used in this specification, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other elements in addition to the elements mentioned.

[0023] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in a manner commonly understood by those skilled in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless they are clearly and specifically defined.

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] The winding device for inserting the coil with an expanded winding range into the upper tool (U) according to the present invention is roughly divided into a former section (10), a former cylinder (20) and a control section (unknown).

[0026] FIG. 1 is a schematic diagram of a coil winding apparatus according to the present invention, and FIG. 2 is a schematic diagram of a coil winding apparatus according to a correct embodiment of the present invention.

[0027] As shown in the figure, the former section (10) is located above the upper tool (U), and the body section around which the wire is wound is formed in multiple stages.

[0028] The former cylinder (20) is installed on the top of the former section (10), and the downwardly extending load section (21) is connected to the end of the former section (10). The length of the former section (10) is adjusted by moving the load of the former cylinder (20) back and forth.

[0029] Next, when the winding of the wire is completed on the former section (10), the upper tool (U) is raised and a control section is provided to control the wire to be inserted between the blades of the upper tool (U).

[0030] Furthermore, since the maximum length of the former section (10) of the present invention is longer than the blade of the upper tool (U), if the upper tool (U) is raised without adjusting the length of the former section (10), the wire wound on the former section (10) will not be inserted into the upper tool (U).

[0031] Therefore, it is desirable that the control unit of the present invention shortens the load length of the poma cylinder (20) in response to the elevation height of the upper tool (U) so that the entire coil with the expanded wire winding range can be inserted inside the upper tool (U).

[0032] However, the former section (10) rotates on one side by a drive section attached to one side of the frame, and the wire is wound along the body section. However, since this has been sufficiently explained in the prior art presented, the operation of winding the wire around the former will be omitted and only the multi-stage shape of the former section, which is a feature of the present invention, will be explained.

[0033] FIG. 3 is a schematic diagram of the maximum length of a former in accordance with a correct embodiment of the invention, and FIG. 4 is a schematic diagram of the minimum length of a former in accordance with a correct embodiment of the invention.

[0034] As shown in the figure, one side of the rod portion 21 of the former portion 10 is connected to the rod of the former cylinder 20, and the rod portion 21 is formed at the center of the former portion 10.

[0035] The former section (10) has a movable former (11) inside, and the movable former (11) has a rail (12) on the inside, and the rail (12) has a plurality of bolts at predetermined intervals in the length direction, and is connected to the former section (10).

[0036] In addition, the rail (12) is located on the inner surface of the former section (10) and extends to the end, and it is desirable to form a locking step (unintentional step) at the end of the rail (12) so that the moving former (11) does not slip out of the former section (10) and the moving former (11) can be hooked onto it.

[0037] Therefore, as shown in Figure 3, the maximum length of the former section (10) is longer than that of the upper tool (U), so even if the upper tool (U) rises to insert the coil wound on the former section (10), the entire coil cannot be inserted into the upper tool (U). Therefore, as shown in Figure 4, the movable former section (11) is inserted inside the former section (10) to reduce the total length of the former section (10), so that the entire wound coil on the former section can be inserted into the upper tool (U).

[0038] Here, it is preferable that the size of the former section (10) is larger than that of the moving former (11) so that the moving former (11) can be inserted inside the former section (10) to minimize pinching of the wound wire.

[0039] In addition, the former section (10) has an inclined surface on one side of the outer periphery of the former section (10) so that the wire wound on the moving former (11) is not pinched between the steps formed by the former section (10) and the moving former (11) when the moving former (11) rises.

[0040] That is, it is desirable to form the wire wound on the moving former (11) on the underside of the former section (10) so that it can straddle the inclined surface when the moving former (11) rises and enters the inside of the former section (10).

[0041] Therefore, the coil winding device of the present invention can insert a coil with an expanded winding range into the upper tool (U) through the moving former (11), but the coil can be inserted without adjusting the length of the upper tool (U). [Explanation of symbols]
