Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a wire hook and guide wire device for a winding machine. Background Art

[0002] Differential-mode inductance is a property of a closed circuit: when the current flowing through the circuit changes, an electromotive force (EMF) is generated to resist the change. This inductance, called self-inductance, is a property of the closed circuit itself. Most electrical products require copper wire wound around a magnetic ring to create an inductor coil. During the differential-mode inductor production process, a winding machine is used to wind the coil.

[0004] However, there is still room for improvement in the wire hooking mechanism of the aforementioned winding machine. For example, when the wire pulley of the wire guide mechanism guides the end of the copper wire above the magnetic ring, the wire may hit other components due to its large swing range and amplitude, potentially damaging them and ultimately the machine.

[0005] Therefore, there is a need to improve the existing technology. Utility Model Content

[0028] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0029] like Figures 1-6 As shown, a wire hooking and conducting device for a winding machine includes a frame 1 and a limit box 2, a wire hooking mechanism 3, a conducting mechanism 4 and a wire pushing mechanism 5 respectively located on the frame 1.

[0030] like Figure 1-Figure 5As shown, a limiting cavity 21 with an upper end opening is provided inside the limiting box 2, specifically, the wire guide mechanism 4 is located above the limiting cavity 21; the wire hook mechanism 3 can be used to pull the copper wire end above the magnetic ring from the center of the magnetic ring downward to the limiting cavity 21; the wire guide mechanism 4 can be used to guide the copper wire end in the limiting cavity 21 to above the magnetic ring; the wire pushing mechanism 5 includes a push rod 51 located on one side of the wire hook mechanism 3 and extending left and right and movable forward and backward, and a wire pushing drive assembly for driving the push rod 51 to move forward and backward and installed on the limiting box 2; in the process of the wire guide mechanism 4 pulling the copper wire upward, the push rod 51 can be used to push the copper wire to one side of the limiting cavity 21 to limit the swing range of the copper wire, thereby preventing the copper wire from swinging greatly, and further preventing the copper wire from damaging other components.

[0031] It can be seen that the utility model utilizes the setting of the limit box 2, and cooperates with the wire pushing mechanism 5 that can be used to push the copper wire to move to one side of the limit cavity 21, so that the push rod 51 can be used to well limit the swing range and swing amplitude of the copper wire, thereby preventing the copper wire from damaging other components due to large-scale swinging during the process of being pulled up by the wire mechanism 4, that is, the utility model can play the effect of protecting components.

[0032] like Figure 3-Figure 5 As shown, preferably, the wire pushing drive assembly includes a wire pushing motor 52 and a transmission assembly; the wire pushing motor 52 is mounted on the side plate of the limit box 2, and the wire pushing motor 52 can drive the push rod 51 to move forward and backward through the transmission assembly. Therefore, the wire pushing motor 52 and the transmission assembly can be used to conveniently and quickly realize the driving of the push rod 51 to move forward and backward.

[0033] like Figure 3-Figure 5 As shown, specifically, the transmission assembly includes a first transmission rod 53, a second transmission rod 54, and a third transmission rod 55; the first end of the first transmission rod 53 is fixed to the output shaft of the wire-pushing motor 52, the second end of the first transmission rod 53 is hinged to the first end of the second transmission rod 54, and the second end of the second transmission rod 54 is hinged to the first end of the third transmission rod 55, and the third transmission rod 55 is arranged to move forward and backward; the first end of the push rod 51 is mounted on the second end of the third transmission rod 55. Therefore, by utilizing the above-mentioned three transmission rods, the output shaft of the wire-pushing motor 52 can be driven to move forward and backward by the sequential transmission of the above-mentioned three transmission rods during its rotation, and the transmission method is convenient and efficient.

[0034] like Figure 3-Figure 5As shown, preferably, the transmission assembly further includes a mounting bracket 56 and a positioning seat 57; the mounting bracket 56 is mounted on the side panel of the limit box 2; the positioning seat 57 is mounted on the mounting bracket 56; and the third transmission rod 55 is movably disposed on the positioning seat 57. Therefore, the mounting bracket 56 can be used to facilitate positioning of the wire pushing mechanism 5, while the positioning seat 57 is provided to facilitate limiting the position of the third transmission rod 55, thereby preventing the third transmission rod 55 and the push rod 51 from deviating from the preset route.

[0035] like Figure 2-Figure 5 As shown, in this embodiment, the mounting bracket 56 is installed on the outside of the side plate (not shown) of the limit box 2. In addition, a through hole 22 is provided on the side plate of the limit box 2 for communicating with the limit cavity 21. The second end of the push rod 51 is inwardly inserted into the through hole 22. However, those skilled in the art will appreciate that if there is sufficient space, the mounting bracket 56 can also be installed on the inside of the side plate of the limit box 2.

[0036] like Figure 3-Figure 5 As shown, preferably, the end portion of the second end of the push rod 51 is provided with a bent portion (not shown) bent backward. Therefore, the second end of the push rod 51 is specifically "L"-shaped to prevent the push rod 51 from slipping out of the copper wire during the wire pushing process. In other words, this design can ensure the stability of the push rod 51 when pushing the copper wire.

[0037] like Figure 3-Figure 5 As shown, preferably, a connecting hole 58 is provided on the second end of the third transmission rod 55, and the second end of the push rod 51 is connected to the connecting hole 58, so that the push rod 51 can be conveniently and stably installed. In addition, those skilled in the art will appreciate that the third transmission rod 55 and the connecting hole 58 can also be connected by a threaded connection to facilitate adjustment of the position of the push rod 51 on the third transmission rod 55.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, two limit boxes 2 and two wire pushing mechanisms 5 are symmetrically provided, respectively; the wire hooking mechanism 3 and the wire guiding mechanism 4 can be used to cooperate with the two limit boxes 2 and the two wire pushing mechanisms 5. Therefore, through the above arrangement, the winding efficiency of the utility model can be improved.

[0039] like Figure 1-Figure 3As shown, as a specific embodiment, the hooking mechanism 3 includes a movable plate 31 that can move up and down and whose end extends into the limiting cavity 21, a hook needle 32 mounted on the movable plate 31, and a hooking drive assembly 33 for driving the movable plate 31 to move up and down. Specifically, a strip hole for the movable plate 31 to move is provided on the side plate of the limiting box 2, but the strip hole should not be too wide; each hook needle 32 is provided with a hook groove corresponding to the copper wire; and the push rod 51 is located on the front side of the hook needle 32. Therefore, the hook needle 32 can be stably pushed to move up and down using the hooking drive assembly 33. In addition, since the overall structure of the hooking drive assembly 33 is prior art, it will not be described in detail here.

[0040] like Figure 1-Figure 3 As shown in FIG. 1 , as a specific embodiment, the wire guide mechanism 4 includes a wire pulley 41 for guiding the end of the copper wire above the magnetic ring, and a wire drive assembly 42 for driving the wire pulley 41. Specifically, the wire drive assembly 42 is configured to drive the wire pulley 41 in forward, backward, left-right, and vertical directions. Similarly, since the overall structure of the wire guide mechanism 4 is also conventional, it will not be further described here.

[0041] In this embodiment, the two ends of the movable plate 31 extend into the two limiting cavities 21 respectively; two hooks 32 are also provided correspondingly and the two hooks 32 are respectively provided at the two ends of the movable plate 31. Of course, two wire wheels 41 are also provided correspondingly.

[0042] The specific operating principle of the utility model is introduced below to facilitate understanding of the utility model:

[0043] refer to Figure 6 First, the various mechanisms of the utility model are set at corresponding positions of the winding machine;

[0044] Next, when the first end of the copper wire is located at the preset position of the magnetic ring, the hook wire driving assembly 33 drives the movable plate 31 and the hook needle 32 to move upward to the preset position;

[0045] Next, the hook wire driving assembly 33 drives the movable plate 31 and the hook needle 32 to move downward until the copper wire is pulled into the preset position of the limit cavity 21, and the hook needle 32 finally stops below the push rod 51; at this time, the push rod 51 is in the original position, specifically, at the rear side of the hook needle 31, so as to prevent the push rod 51 from affecting the normal downward movement of the hook needle 31;

[0046] Next, the wire pushing motor 52 drives the push rod 51 to move backward through the transmission assembly until it pushes the copper wire to the rear side of the limiting cavity 21 (i.e. Figure 3At the same time, the wire driving assembly 42 is actuated and drives the wire wheel 41 to gradually guide the copper wire in the limiting cavity 21 to the top of the magnetic ring;

[0047] Next, when all the copper wires are moved into place, the wire pushing motor 52 drives the push rod 51 to move forward and reset;

[0048] Next, the hook line driving assembly 33 drives the movable plate 31 and the hook needle 32 to move upward to the preset position again, and then continues to repeat the above steps.

[0049] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
